Progress Toward Implementing Superfund: Fiscal Year 1987
FOREWORD
We are pleased to submit the Environmental Protection Agency's first Annual
Report on the progress made by the Agency during fiscal year 1987 in implementing
the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA
or Superfund), as amended by the Superfund Amendments and Reauthorization Act
(SARA) of 1986. This Report, and the information it contains, is required by
CERCLA section 301(h). The Report includes a description of minority firm
participation in Superfund contracts, and of our efforts to encourage their
participation, as required by section 105(f). The Report meets the requirement
of section 301(h)(l)(E) for an annual update on progress being made on sites
subject to review under section 121(c) . In addition to satisfying the section
301(h)(l)(E) requirement, this Report satisfies the reporting requirements of
section 121(c). The report of the EPA Inspector General on his findings
concerning the reasonableness and accuracy of the information in this Report
related to EPA's activities, as required by section 301(h)(2), is included as
Appendix F.
EPA made significant progress and accomplished much during fiscal year 1987
in implementing CERCLA as amended. This progress occurred despite adverse
circumstances, including a hiatus in Superfund's funding preceding
reauthorization. The year's accomplishments, in the removal program
particularly, and in the remedial program in most cases, met or exceeded our
targets for 1987. Much of this progress was characterized by efforts to
implement many new provisions. In particular, provisions specific to the long-
term remedial program that are changing the nature of EPA's responsibility, and,
consequently, our relationship with the public, State and local governments,
potentially responsible parties, and other Federal departments and agencies.
In addition to providing an overall perspective on progress in the past
fiscal year, the Report also contains information that Congress specifically
requested in section 301(h)(l), including a detailed description of each of 70
feasibility studies that were completed in fiscal year 1987; a report on the
status of remedial actions, including enforcement activity, in progress at the
end of the fiscal year; and an evaluation of newly developed feasible and
achievable permanent treatment technologies.
This first Annual Report to Congress on Superfund implementation progress
will aerve as the f oundatidfnTtnc subsequent Reports. We welcome your ideas and
suggestions on how we mignt^impifove the Report for future years.

Progress Toward Implementing Superfund: Fiscal Year 1987
1.0 EXECUTIVE SUMMARY
This Annual Report to Congress is required by section 301(h) of CERCLA, as
amended by the Superfund Amendments and Reauthorization Act (SARA) of 1986. The
Report provides an overview of progress made by the Environmental Protection
Agency (EPA) in implementing a wide range of Superfund program activities during
fiscal year 1987. Particularly noteworthy are the field accomplishments
including the number of removal actions, pre-remedial activity completions, and
remedial project starts. The Agency also made progress in improving management
systems, increasing State and local government and public involvement, developing
implementation guidance, and carrying out rulemaking activities.
The Report documents progress made in the removal, pre-remedial, and
remedial programs, including enforcement activities, and also contains specific
information required by section 301(h)(l), such as the status of remedial
projects, the development of new technologies, and estimates of resources
required to complete the Superfund program. The Report also describes the
participation of minority firms in Superfund contracting, as required by section
105(f).
The fiscal year began with the enactment of SARA, which ended an extended
period of steadily declining activity in the Superfund program. This drop in
the level of activity was caused by the near depletion of the Hazardous Substance
Trust Fund (or Superfund) due to the absence of reauthorization legislation. As
a consequence of SARA's passage in October 1986, the Agency's principal
objectives for 1987 were to:
• Accelerate the program after a one-year slowdown;
• Implement CERCLA, as amended by SARA; and
• Undertake improvements to management systems.
This Report describes how EPA achieved these objectives in the various program
areas.
Although this Report is primarily directed to the members of Congress, EPA
anticipates that the public, industry representatives, and persons interested in
the Superfund program will find the Report useful as a basic reference document.
The report required by section 301(h)(2), on the results of the EPA
Inspector General's review of this Report for reasonableness and accuracy, is
included in Appendix F. The final paragraph of this Executive Summary provides
the location in the Report of all information specifically required by statute.
Numbers associated with outputs and resources in this Report may differ
slightly from previously published numbers due to accounting differences by
various EPA offices and corrections and adjustments made following the close of
the fiscal year.

Progress Toward Implementing Superfund: Fiscal Year 1987
Fiscal 1987 Accomplishments
Overall, EPA's accomplishments in the removal and remedial programs equalled
or exceeded those in any previous year. EPA met or exceeded targets set for 23
of 27 Superfund progress measurements used by EPA senior managers. Although EPA
missed targets set for several remedial program measures, the Agency averaged a
78 percent completion rate.
The Agency initiated a record number of removal action starts (254), signed
a significant number of remedy selection decision documents (records of decision
or RODs) (75), started a record number of remedial designs for construction of
selected remedies (94), and began 54 new remedial action construction projects.
The term "start" as used in the Report does not necessarily mean the beginning
of field work. The Agency uses the term "start" to indicate that funds have been
obligated through the contracting process so that field work may begin. Figures
used for accomplishments in the Report, for the most part, are based on national
data. Figures for some activities are shown in more detail, e.g., removal
actions by EPA Region.
On September 30, 1987, the end of the fiscal year, remedial activities were
underway at 533 Superfund sites. There were 642 ongoing remedial projects: 548
remedial investigation/feasibility studies (RI/FSs), 15 FSs, and 79 remedial
actions (RAs). The status of these projects was as follows:
• Of the 563 RI/FS and FS projects, 48 (8.5 percent) were ahead
of schedule; 148 (26.3 percent) were on schedule; 323 (57.4
percent) were behind schedule; and there was no available
completion estimate for 44 (7.8 percent).
• Of the 79 RA projects, 13 (16.5 percent) were ahead of
schedule; 24 (30.4 percent) were on schedule; 31 (39.2
percent) were behind schedule; and there was no available
completion estimate for 11 (13.9 percent).
Project delays can be attributed to many factors, including the hiatus in
program funding during the FY85-86 period, the need to complete contracting
arrangements before projects can begin, and EPA employee turnover. The Agency's
goal is to complete RI/FS projects in 18 to 21 months. Historically, however,
they have taken 24 to 35 months to complete.
The Agency developed numerous management initiatives that are expected to
expedite implementation of Superfund program activities in the future. Some of
the most important include streamlining the RI/FS process, diversifying the
remedial and removal contracts and delegating control of those contracts to the
Regions, and developing a second generation management information tool, the
CERCLA Information System (CERCLIS). Other efforts now underway entail improving
EPA's working relationship with States and the other Federal departments and
agencies, developing and applying a variety of new technologies, and encouraging
the public to participate more actively in the Superfund program.

Progress Toward Implementing Superfund: Fiscal Year 1987
Even before the enactment of SARA, EPA began planning for its
implementation. Several workgroups were formed late in fiscal year 1986 to begin
the analysis required to implement the anticipated major amendments to CERCLA.
The most significant efforts focused on the required revisions to the National
Contingency Plan (NCP) and the Hazard Ranking System (MRS) methodology, and on
the development of regulations to implement the Technical Assistance Grant (TAG)
provision. The TAG interim final regulation was published on March 23, 1988.
On October 24, 1986, one week after SARA was passed, EPA issued a "date of
enactment" memorandum that provided guidance on how to make the transition from
operating procedures under the old law to procedures that would address the
priorities and achieve the objectives under CERCLA, as amended. The highest
priority was initiating construction projects at sites already in the remedial
pipeline. On December 24, 1986, the Assistant Administrator for Solid Waste and
Emergency Response (OSWER) issued important interim guidance on criteria to be
used in selecting Superfund remedies.
Another early initiative involved EPA's participation in drafting the
Executive Order that transferred the authority and responsibility for
implementing CERCLA from the President to EPA and other Executive Branch
organizations. The President signed Executive Order 12580 on January 23, 1987,
following months of work by staff at EPA, the Office of Management and Budget
(OMB), the National Response Team, and other agencies. After receiving its
responsibilities from the President, EPA developed internal policy documents that
redelegated the Administrator's responsibilities to Regional Administrators (RAs)
and Assistant Administrators (AAs).
On February 26, 1987, the Administrator, Lee M. Thomas, signed EPA's interim
delegations of authority, which made implementation of new Superfund provisions
possible, pending final resolution of how authority and responsibility would be
allocated within the Agency. On September 13 and 21, 1987, the Administrator
signed the last two of a series of decision memoranda, completing most of the
internal delegations assigning EPA's CERCLA responsibilities.
As a result of early efforts, EPA met CERCLA's deadlines for revising the
reportable quantity (RQ) regulations and initiated several other RQ rulemakings.
EPA prepared a Report to Congress required by SARA on the transportation of
hazardous materials, and published an important interim final rule on
Reimbursement to Local Governments on October 21, 1987.
Implementing the CERCLA-mandated revisions to the NCP has been a major
effort for the past year, involving a broad and comprehensive rulemaking process
to revise as well as restructure the document. All existing subparts of the NCP
will be revised, (some will be consolidated), and several new subparts will be
added. The principal revisions apply to the removal program and the selection
of remedy process. In addition, other regulations that are major in their own
right are part of the NCP revisions now underway, including State involvement and
Administrative Record regulations. The revised NCP was proposed in December 1988
(53 FR 51394).
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Another key initiative was to issue interim guidance for implementing those
Superfund provisions that became effective with the passage of SARA and were not
dependent upon promulgation of regulations. During the year, EPA issued 10 such
interim guidance documents. As part of the CERCLA enforcement program, several
policy and guidance documents were developed, some in response to CERCLA
provisions, to further the program's goals. Those that have been finalized
include Streamlining the Settlement Process (February 12, 1987) and Nonbinding
Allocations of Responsibility (NBARs) (May 28, 1987); interim guidance on de
minimis settlements was issued on June 19, 1987.
On March 5, 1987, EPA held a national teleconference designed to communicate
CERCLA's provisions to a broad range of EPA Regional and State program staff.
After the teleconference, six 2-day conferences were held to describe and discuss
the implementation issues and policies with EPA staff from the 10 Regional
offices and with State program staff. Also, throughout the year, EPA conducted
a variety of outreach and training activities designed to assist EPA Regional and
State staff. Headquarters' program staff and Regional staff coordinated visits
to all EPA Regions to provide hands-on assistance in developing RODs and
incorporating CERCLA requirements into projects in progress.
With support from EPA, the Agency for Toxic Substances and Disease Registry
(ATSDR) conducted 106 health assessments, published procedures for requesting
health assessments, and issued a manual on conducting health assessments. Of the
106 health assessments conducted, 60 were at National Priorities List (NPL) sites
in 28 States, and 45 were at non-NPL sites in 21 States. One health assessment
was conducted in response to a public petition. In addition, ATSDR also
completed 1,467 health consultations in 50 States, the District of Columbia, and
several territories and foreign countries and awarded 11 cooperative agreements
to States, enabling them to develop the capability to perform their own health
assessments. ATSDR did not issue any health advisories in FY87.
Existing technical support programs were continued and several new research
programs were begun to satisfy the need to better assess the health risks posed
by hazardous substances and to develop treatment technologies that provide
permanent protection of human health and the environment. In response to the
mandate for technology development, EPA carried out research in several areas in
addition to the Superfund Innovative Technology Evaluation (SITE) program. This
research included: treatment technology evaluation, which addressed four major
treatment processes and continued research on ground-water cleanup alternatives;
personnel protection research directed toward safety concerns, such as safety
procedures and protective clothing and equipment; and a university research grant
program to conduct applied research on measurement and monitoring methods and on
in situ treatment of hazardous waste.
In response to CERCLA-authorized health-related research, EPA, ATSDR, and
the National Institute for Environmental Health Sciences (NIEHS) agreed on an
integrated research effort in which each agency will focus on specific research
areas. EPA will concentrate on risk assessment techniques, toxicological test
methods, and exposure assessment methodology. ATSDR1s research will be related
to CERCLA-mandated health assessments, and NIEHS will support multidisciplinary
biomedical research through university grants.
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
The EPA Office of Research and Development (ORD) also provided a range of
technical assistance during the year. Endangerment assessments of 20 sites were
conducted and a risk assessment review group was established. Chemical toxicity
profiles were prepared for 74 chemicals; RQ documentation was prepared for 50
suspected carcinogens, along with draft documentation for 191 others; and 12
rapid response assessments of specific chemicals were made. ORD also provided
engineering assistance to Regional offices for 35 sites and monitoring support
to Regional offices and the National Enforcement Investigations Center (NEIC) for
400 sites.
Because of the potential for adverse ambient air impacts from Superfund
site emissions, the Office of Air Quality Planning and Standards (OAQPS) and the
Regional Air Program Offices were given increased responsibility and resources
to provide technical assistance to the Superfund program in evaluating air
impacts and to advise the Superfund Regional offices on appropriate removal and
remedial actions for Superfund sites where air issues are of concern. An
Air/Superfund Coordinator has been designated at Headquarters and in each
Regional Air Office to facilitate coordination between the Air and Superfund
programs.
The cost recovery program focused on projecting cost recovery revenue for
the next 5 years and on prioritizing sites for cost recovery based on statutes
of limitations and availability of potentially responsible parties (PRPs). EPA
Regional offices referred 37 sites with a combined dollar value of approximately
$30,500,000 to Headquarters for cost recovery action. The Agency completed 62
cost recovery settlements, including settlements that did not require litigation,
with a total reimbursement to the Trust Fund of $18,866,000.
Removal Program Activities
Removal actions are relatively short-term actions designed to protect public
health, welfare, or the environment. Removal actions may be undertaken in
response to an emergency, such as a fire, chemical leak, or explosion. Removal
actions can be quite extensive, involving significant engineering and requiring
several million dollars to complete.
In a program with a high level of success since it began in fiscal year
1981, by far the largest number of removals was conducted this year. Using Fund
resources, 254 removal actions were begun during the year and 195 were completed.
Responsible parties contributed an additional 50 removal action starts and 31
removal completions. Also, the program reached a major milestone this year by
beginning action on its 1,000th removal, ending the year with a 7-year program
total of 1,057 Fund-financed removal action starts. The Agency also oversaw the
removal activities of responsible parties, States, and local governments at 422
sites.
The removal program reissued four Regional Emergency Response Cleanup
Services (ERGS) zone contracts, and awarded the following additional contracts:
two Technical Assistance Team (TAT) contracts; four dioxin contracts; one cleanup
standards 8(a) (minority) contract; two Regional ERCs, both of which are 8(a)
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
(minority) contracts; one site-specific cleanup contract; and two environmental
emergency response unit (EERU) contracts. These contracts in combination provide
the technical assistance and cleanup service that EPA needs to implement an
effective removal program.
In addition, EPA began working to implement the recommendations of the On-
Scene Coordinator (OSC) Management Support Task Force. The recommended changes
are intended to assist the OSCs in meeting current administrative requirements
for financial management, contract management, and documentation for cost
recovery. Five Regions established Administrative Support Units to implement the
recommendations, and the remaining Regions will establish similar units in FY88.
Pre-Remedial Program Activities
Pre-remedial activities are investigative and analytical activities
undertaken to evaluate the threat, or potential threat, to human health or the
environment posed by conditions at a site, and to determine the need for further
action and set priorities for that action. The Agency made substantial progress
toward meeting the statutory goal of completing preliminary assessments (PAs) by
January 1988 on all sites in CERCLIS at the time CERCLA was amended. PAs were
completed on more than 4,000 sites, and site inspections (Sis) on more than 1,340
sites. Ninety-nine sites (including 32 Federal facilities) were listed as NPL
sites, and 64 sites (including one Federal facility) were proposed for listing.
In addition, the pre-remedial program substantially completed development of
Update 7 to the NPL in FY87, and, on June 24, 1988, (53 FR 23988) proposed 229
new sites.
The pre-remedial program also increased the level of effort for conducting
a PA so that lead agencies can more effectively identify sites that require Sis.
Guidance is also being developed to direct more resources to SI activity at sites
most likely to be proposed for the NPL.
As required by section 105 of CERCLA, a major effort to revise the HRS was
undertaken during the year that would ensure, "to the maximum extent feasible,"
that the HRS accurately assesses the relative risk to human health and the
environment posed by potential NPL sites. Accordingly, a number of new
evaluation factors are being added to the HRS, including the threat that the
contamination poses to the human food chain and ambient air quality, and the
effect of contamination of surface water used for human consumption and for
recreational purposes. Although the rule will not become effective in time to
meet the statutory deadline established by section 105(c)(l) (October 1988),
revision to the HRS is on an accelerated schedule, and the final rule is expected
in the second half of fiscal 1989.
Remedial Program Activities
Remedial actions are generally undertaken at complex sites and usually take
longer than removal actions. Considerable study is required to select the most
effective cleanup action, which may cost millions of dollars to implement.
Project accomplishments for the remedial program were significant: 183 RI/FS
starts (123 "first start" RI/FSs and 60 subsequent RI/FSs); 75 RODs (58 initial
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
RODs and 17 subsequent RODs) were signed; 94 remedial design '(ED) starts; 54 RA
starts; 8 RA completions; and 5 sites entered the operation and maintenance
phase.
A significant number of remedial actions were initiated or completed by
PRPs. Of the 123 first-start RI/FSs, 47 are being conducted by PRPs. Twenty-
four of the 94 remedial design starts were begun in accordance with consent
decrees. At the end of the year, several additional consent decrees were in the
final stages of preparation.
To implement the remedy selection provisions of CERCLA, the Agency issued
three interim guidance documents: Interim Guidance on Superfund Selection of
Remedy (December 24, 1986); Interim Guidance on Compliance with Applicable or
Relevant and Appropriate Requirements (July 9, 1987); and Additional Interim
Guidance for FY87 Records of Decision (July 24, 1987).
In addition, throughout FY87 EPA continued to draft guidance for conducting
remedial investigations and feasibility studies under CERCLA and for preparing
RODs and proposed plans. Interim ROD guidance is scheduled for release in FY88;
a final guidance document, however, will not be issued until the revisions to the
NCP are completed.
The decisionmaking process underlying the selection of a remedy for a given
site is a multi-step process. Remedial alternatives analyzed in the feasibility
study are developed by screening the universe of potentially applicable
technologies and process options. By using information on contaminant types and
concentrations and onsite characteristics from the remedial investigation site
characterization, technologies and process options that clearly are not
appropriate are screened out. Each remaining alternative is evaluated with
respect to nine criteria developed to address the statutory requirements of
CERCLA section 121. The criteria include such factors as overall protection of
human health and the environment, long-term effectiveness and permanence, and
reduction of toxicity, mobility, or volume of contaminants. Based on the results
of the evaluation, the Regional Administrator or Assistant Administrator, in
consultation with appropriate State personnel, selects the remedy for a site.
When the remedy has been selected, the ROD is prepared.
There were 75 RODs signed in FY87, involving a total of 119 remedial
components. Thirty-two of these components will employ at least one type of
treatment that will permanently and significantly reduce the volume, toxicity,
or mobility of the hazardous substances, pollutants, and contaminants at the
sites. Thirty-five remedies involve containment components to address non-
residual waste. Ground-water pump and treatment actions are components of 32
of the selected remedies. Finally, thirteen remedies provide for alternative
water supplies, and seven recommend no futher action. (See section 2.3.8 of the
Report for a more detailed explanation.)
EPA has taken several steps toward creating a full-scale program for the
development and evaluation of permanent technologies (i.e., technologies that
provide a permanent solution to contamination problems at a site) by initiating
the SITE program and implementing one of its major components, the SITE
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
demonstration program (DP). Two solicitations for technologies for the DP have
been published -- the first, in February 1986, and the second, in January 1987.
EPA is working with 11 technologies selected during 1986. One demonstration was
completed and five more are planned.
New technologies were also generated by EPA activities riot directed
primarily toward this goal: treatability studies done as part of FSs at
Superfund sites were undertaken to determine the comparative effectiveness of
various remedies; the Superfund Technology Support Project (STSP), a technical
assistance program, was initiated to encourage the use of new technologies; and
a worldwide survey of treatment technologies was conducted. Also, in response
to CERCLA's requirement to establish a program for a 5-year review of sites at
which hazardous substances remain after completion of a remedial action, EPA
developed a draft policy that is included in the proposed NCP.
The remedial program awarded two Field Investigation Team (FIT) contracts
to provide support for the pre-remedial program. In addition, EPA awarded three
contracts to minority business firms; two contracts to perform remedial response
activities and one contract to provide remedial response for a specific site.
Program Management Initiatives
Two major remedial project management support activities were initiated
this year:
(1) The Alternative Remedial Contracts Strategy (ARCS). ARCS
will promote the continuity of contractor performance from
RI/FS through construction management (or RA), increase the
level of competition for contract awards, and facilitate the
delegation of contract management to the Regions. Contract
awards under this program in the two pilot Regions began in
December 1987, and procurement actions will begin in the
remaining Regions next year.
(2) The RI/FS Improvements Initiative. This effort has several
objectives: (i) to contain project planning activities
within a 3-month period after project initiation; (ii) to
ultimately reduce the overall RI/FS process to an 18-month
schedule; (iii) to reduce overall costs; and (iv) to improve
the technical quality of RI/FSs. A report issued to the
Regions on July 23, 1987 discussed several initiatives aimed
at improving performance on RI/FS projects and proposed
implementation strategies for improving project performance
while concurrently streamlining the RI/FS schedule. These
initiatives attempt to provide a realistic strategy for
implementing a phased RI/FS schedule that would meet CERCLA
objectives without requiring major changes to the remedial.
program.
Reorganization and reallocation of program responsibilities was another
significant initiative during the year. Early in the year, in anticipation of
10
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
the CERCLA amendments, EPA decided to restructure the Office of Emergency and
Remedial Response (OERR) to improve management's ability to implement the new
law, to focus efforts on meeting statutory goals and schedules, and to facilitate
the drafting of major rules, such as the NCP and HRS revisions. EPA Regional
offices have assumed an increasingly important role in the Superfund program as
a result of increasing internal delegation of program responsibilities to the
Regional level and expansion of computer capabilities for planning workloads and
tracking program progress.
The removal program, supported by four zone ERGS contractors, developed
several contracts initiatives that will be implemented over the next 2 years.
EPA implemented a strategy for awarding smaller removal contracts, "mini-ERCS,"
on a Regional basis. EPA also plans to provide additional coverage by splitting
one of the ERGS zones into two smaller zones and awarding a new contract for each
of them.
Additionally, EPA is developing a new contracting approach (projected for
FY89) that involves prequalifying contractors within each Region (or an even
smaller geographical area) so that when a specific removal is required within a
certain area, a contractor can be chosen from among the select group of
prequalified firms in that area.
As noted earlier, EPA created a second generation CERCLIS by incorporating
into CERCLIS part of the information and data contained in five different
systems: CERCLIS (first generation); the Superfund Comprehensive Accomplishments
Plan (SCAP); the Removal Tracking System; the Case Management System; and the
Remedial/Removal Financial System Site File. The expanded CERCLIS is the
national Superfund management, tracking, and reporting tool. Site-specific data
files became fully operational on November 1, 1987, and, by January 1, 1988,
CERCLIS was being used to track the SCAP and Agency-wide progress measures.
The SCAP is the planning mechanism that drives the allocation of resources
for remedial activities. With the incorporation of the SCAP into the CERCLIS
management system, the Regions became responsible for the planning and reporting
that determine the adequacy of budgetary allotments and how Regional
accomplishments are reported. To make the SCAP a better planning and site
management tool, EPA used an integrated approach to SCAP development and
maintenance, which was implemented in several ways:
• Target setting and reporting for Fund-financed activities
and enforcement/PRP activities were combined;
• Uniform reporting formats combining removal, remedial, and
enforcement information were developed;
• The enforcement case budget was integrated with the SCAP;
and
• Regions began planning the use of Technical Enforcement
Support contract and interagency agreement resources on a
11
-------

site-specific basis, the basis on which remedial activities
are planned.
Finally, senior OSWER management and staff have spent a significant amount
of time identifying and resolving the complex issues raised by integrating the
Resource Conservation and Recovery Act (RCRA) and CERCLA programs in response to
the requirements of CERCLA section 121, which recognizes the significant impact
the regulations and policies established for one program can have on the other.
Their efforts will be reflected in both the NCP proposal and forthcoming manual
on Superfund compliance with other laws. The current focus of the RCRA/CERCLA
Task Force is the proposed RCRA section 3004 corrective action rule.
Other Implementation Activities
EPA took a number of actions with regard to Federal facilities. EPA added
32 Federal facilities to the NPL, the first Federal facilities to be included,
and another 16 were proposed for listing. In addition, EPA, the U.S. Department
of the Army, and the State of Minnesota signed the first Interagency Agreement.
EPA also established the Federal Facilities Task Force, which works with States
and EPA Regional offices to ensure that Federal facilities comply with the
section 120 provision that Federal facilities satisfy applicable CERCLA and RCRA
requirements. EPA has 16 facilities subject to this provision and began in FY87
to prepare its Report to Congress on progress made to bring the facilities into
compliance with the provisions of section 120.
EPA established the Federal Agency Hazardous Waste Compliance Docket to
make information available to the public about Federal facilities and to give
notice of CERCLA actions concerning Federal facilities. The initial docket
listed 1,094 facilities. In accordance with the 1987 Executive Order 12580,
Federal departments and agencies are responsible for conducting PA/SIs of the
Federal facilities they own or operate. EPA established a deadline of April 17,
1988, for submission of Federal facility pre-remedial activity reports. Also,
EPA proposed regulations implementing section 120 restrictions on the transfer
of U.S. government property on which a hazardous substance was released, disposed
of, or stored for a year or more.
Much of the Superfund program is implemented through contract services, and
EPA is continuing efforts to increase the proportion of contract dollars that is
awarded to minority firm contractors. This year the value of the minority firm
share of Superfund contract dollars was $38,000,000, which is 6 percent of the
$603,900,000 total obligated during the year. Of the total, direct: procurement
contracts represented $31,300,000 (9 percent of the total dollars awarded); the
share of cooperative agreement dollars awarded was $2,100,000 (22 percent); and
the share of interagency agreement dollars was $4,600,000 (2 percent).
During the fiscal year, EPA conducted several activities to promote the
participation of minority firms. The Office of Small and Disadvantaged Business
Utilization (OSDBU) sought the assistance of the Minority Business Development
Agency (MBDA) of the Department of Commerce. EPA issued information on
contracting processes and held conferences, seminars, and training workshops to
inform minority firms about Superfund contracting opportunities. Also, other
12
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Federal departments and agencies involved in the Superfund program were
encouraged to increase awards to minority firms. EPA requires these departments
and agencies to submit reports on contracts that have been awarded.
EPA Superfund implementation activities are funded from the Hazardous
Substance Trust Fund. Executive branch departments and agencies other than EPA
use two sources of funding to implement Superfund activities: the Trust Fund and
monies budgeted independently of Superfund as part of the President's annual
budget submission. During the fiscal year, EPA expended a total of
$1,050,748,900 in Trust Fund monies for CERCLA implementation, including SARA
Title III activities. Other Federal departments and agencies spent $478,193,900
to fund the implementation of their Superfund activities, including $66,148,000
in Trust Fund monies transferred via the EPA Superfund Interagency Budget and
site-specific interagency agreements.
Congress provided EPA with $3,964,000,000 in budget authority for the
implementation of CERCLA, as amended, for the 3-year fiscal period 1987 through
1989. The actual level of funds obligated annually may be slightly less than the
level of budget authority provided. EPA is working to collect the data necessary
to include estimates for completion of CERCLA requirements in the FY88 Report to
Congress. EPA is also developing an estimate of unfunded liability beyond 1991
for projects currently in the remedial pipeline. In FY88, the Agency's ability
to forecast costs should be improved by promulgation of the proposed NCP and by
gaining another year's experience in implementing the provisions that SARA added
to CERCLA. Better coordination with other agencies and departments also should
help refine projections.
Finally, EPA participated in four Congressional hearings before the Senate
Environment and Public Works Committee on Superfund implementation. No
implementation hearings were held by House committees.
Statutory Deadlines and Report Requirements
Congress imposed seven deadlines on EPA in FY87 through provisions added
to CERCLA by SARA. EPA met two of these deadlines: promulgating revisions to
RQ regulations under section 102(a), and soliciting innovative technologies for
research and development as required by section 311(b)(5)(B). The following were
not submitted to Congress by their respective deadlines: this Report on CERCLA
implementation progress, required by section 301(h)(l); the report on progress
in the research, development, and demonstration programs, required by section
311(e); and the study on hazardous waste sites on Indian lands, required by
section 126(c). All of these reports have now been submitted.
Also, statutory deadlines established for promulgating procedures to notify
local and State officials and other interested persons of limitations on the
payment of claims under section lll(o) and for submitting a report to Congress
under section 120(e)(5) on implementing CERCLA at EPA facilities were not met.

2.0 RESPONDING TO RELEASES OF HAZARDOUS SUBSTANCES
CERCLA gives the Federal government authority to respond to uncontrolled
releases of hazardous substances and to develop long-term solutions to the
nation's gravest hazardous waste problems. CERCLA provides for a broad program
of reporting, investigation, and response to releases or threats of releases of
any hazardous substance, or of any pollutant or contaminant that may present an
imminent and substantial danger to public health, welfare, or the environment.
2.1 Notification and Reporting of Hazardous Substances
2.1.1 Overview
Sections 103(a) and 103(b) of CERCLA require that persons in charge of
vessels or facilities from which a hazardous substance is released in quantities
equal to or greater than its RQ immediately notify the National Response Center
(NRG).*
Section 102(b) of CERCLA establishes one pound as the standard RQ for all
releases of hazardous substances, except those for which RQs were established
pursuant to section 311 of the Clean Water Act. Section 102(a) authorizes the
Administrator of EPA to adjust all of these RQs by regulation, thereby allowing
the Federal government to focus its resources on those releases that are most
likely to pose potential threats to public health and welfare and the
environment.
Under section 103(f)(2) of CERCLA, the reporting requirements for certain
continuous releases of hazardous substances may be less stringent than those
otherwise specified under sections 103(a) and (b). Section 103 of CERCLA also
provides a reporting exemption for federally permitted releases, which are
defined as releases permitted under certain other State or Federal programs.
2.12 Past and Ongoing Activities
On May 25, 1983, EPA proposed a rule to clarify procedures for reporting
releases of CERCLA hazardous substances and to adjust RQs for 387 CERCLA
hazardous substances (48 FR 23552). The May 25, 1983, Notice of Proposed
Rulemaking (NPRM) also compiled for the first time the list of hazardous
substances defined under section 101(14) of CERCLA. On April 4, 1985, EPA
promulgated a final rule that clarified reporting procedures and finalized RQ
adjustments for 340 hazardous substances (50 FR 13514). On September 29, 1986,
EPA promulgated RQ adjustments for an additional 102 hazardous substances (50 FR
34534) .
The NRG has the capability to accept release notifications on a 24-hour
basis. Its national toll-free number is (800) 424-8802; in the Washington,
B.C. metropolitan area, the number is (202) 267-2675.

2.13 Progress in Fiscal Year 1987
On March 16, 1987, EPA published two proposed rules to adjust the statutory
RQs for CERCLA potential carcinogens and radionuclides (52 FR 8140 and 52 FR
8172). Substantial effort during the fiscal year culminated in several
rulemakings after the close of FY87. On March 2, 1988, EPA published a proposed
rule to adjust the RQs for lead and lead compounds and to delist ammonium
thiosulfate as a CERCLA hazardous substance (53 FR 6762). A proposed rule
explaining the scope of the reduced reporting requirement for continuous releases
was issued on April 19, 1988 (53 FR 12868). Also, the Agency published a rule
on the reporting exemption for federally permitted releases (53 FR 27268, July
19, 1988).
On October 1, 1987, the Emergency Response Notification System (ERNS) became
operational. Notifications of releases reported directly to EPA Regional offices
and to the U.S. Coast Guard district offices are now entered electronically into
a central data base, along with NRC reports. ERNS provides EPA with a more
comprehensive perspective on release notifications nationwide.
22 The Removal Program
2.2.1 Overview
Removal actions, authorized under CERCLA section 104(a), are generally
short-term actions intended to respond to near-term threats to human health and
the environment. In some cases where additional response action is otherwise
appropriate, removal actions serve to protect the public and the environment
until a long-term solution can be instituted; in others, the removal action
suffices as the solution to the problem.
Removal actions may include the following activities: treatment,
excavation, pumping, incineration, barrier installation, provision of an
alternate water supply, or temporary relocation of residents. Superfund-financed
removals can be conducted at both National Priorities List (NPL) and non-NPL
sites. Removal actions also may be conducted and financed by potentially
responsible parties (PRPs).
SARA mandated two significant changes in the removal program. First, SARA
amended CERCLA section 104(c), increasing the limits on removal actions from 6
months and $1,000,000 to 1 year and $2,000,000. A new exemption to these limits
can apply when "continued response action is otherwise appropriate and consistent
with the remedial action to be taken." Second, CERCLA section 104(a), as
amended, requires that a removal action contribute, to the extent practicable,
to the efficient performance of a long-term remedial action. EPA issued guidance
in April 1987 to implement the section 104(a) provision and the section 104(c)
statutory exemptions. During FY 1987, EPA approved 23 exemptions to the
statutory time limit and 11 exemptions to the $2,000,000 ceiling.

-------
Progress Toward Implementing Superfund: Fiscal Year 1987
222 Progress in Fiscal Year 1987
The Agency initiated a total of 254 Fund-financed removal action starts and
restarts and 195 removal actions were completed using Superfund resources in
FY87. This is the second largest number of completions since the program began
in December 1980. The enforcement program issued 67 administrative orders for
removals, and PRPs started an additional 50 removals and completed 31. Removal
action settlements climbed to 57, totaling more than $27,000,000. At 10
facilities, PRPs undertook independent response actions. A total of 85 removal
sites were cleaned up during the year; 83 were Fund-financed, and two were
financed by PRPs. A site is determined to be cleaned up when no further action
is anticipated. Exhibit 2.2-1 lists, by State, the number of removals financed
by Superfund.
222.1 Polychlorinated Biphenyl (PCB) Removals
Removals conducted in response to PCB and/or dioxin contamination during
FY87 comprised 20 percent of total removals. PCBs were found in soil or oil;
dioxin contamination was usually found only in soil.
In early 1987, PCB compounds were discovered in 68 disposal pits along
natural gas pipelines owned by a private company. In response, EPA appointed a
national task force to investigate the disposal practices of the interstate
natural gas pipeline industry. The task force initiated several actions:
• A nationally coordinated effort to identify other pipeline
companies using earthen disposal pits;
• Preliminary site assessments to determine whether there was
any immediate need for removal actions; and
• Enforcement negotiations with PRPs to compel them to clean
up any contamination.
The task force ultimately identified a total of 78 sites requiring
preliminary site assessments. In all cases, the PRPs undertook the removal
actions.
2222 The 1000th Removal - Moreland Site
EPA initiated the 1000th Superfund emergency removal action in August 1987
at the Moreland site in Commack, New York. The Moreland site typifies EPA's
emergency removal actions.
On July 24, 1987, the New York State Department of Environmental
Conservation (NYSDEC) alerted EPA to two leaking cylinders in a field outside
of Commack, New York. After consulting a cylinder specialist and conferring
with the manufacturer, EPA determined that the cylinders contained hydrogen
fluoride, a highly corrosive substance often fatal to humans when inhaled. One
of the cylinders was leaking through the valve assembly, and the other was
leaking through pinholes in its base. The release of the cylinders' contents

presented an imminent and substantial danger to public health and the
environment.
EPA began the removal action on July 24, 1987 by mobilizing the Emergency
Removal Cleanup Services personnel and stabilizing the two cylinders in two
overpack drums filled with lime. On July 30 and 31 and August 1 and 2, 1987,
EPA emptied the two cylinders by allowing their contents to gravity feed into
an in-ground reactor vessel on site. On August 11, 1987, the empty cylinders
were shipped back to their manufacturer in Cleveland, Ohio, for dismantling.
The removal action was officially completed on September 3, 1987, when the
reactor vessel was removed.
2223 The Environmental Response Team
The Environmental Response Team (ERT) provides training to Regions and
States, as well as technical support for difficult or unusual removal and
remedial actions. Regional offices may request the ERT's assistance if the
Region determines that additional technical expertise is required to remove or
remediate a spill or other site contamination. The ERT assisted all 10 Regional
CERCLA and RCRA offices with 195 instances of spills or site contamination. In
particular, the ERT provided support for the air monitoring conducted in the Love
Canal Habitability Study; the site-safety plan negotiations at the Bloomington,
Indiana, PCB site; the innovative technology demonstration at the Peak Oil Site
in Tampa, Florida; and the remedial activities for ground-water contamination at
the North Road site in Reeders, Pennsylvania.
During FY87, the ERT presented approximately 100 training courses to over
3,500 EPA, State, and local employees. Topics discussed include site safety;
sampling methods (air and other media); first response; incident mitigation; and
ground-water treatment methods.
222A Monitoring of Removal Activities
When CERCLA funds are not used, EPA oversees the cleanup activities of PRPs,
States, localities, or other parties to ensure that adequate cleanup takes place.
By the end of FY87, EPA had conducted on-site monitoring for 422 cleanup actions
involving hazardous substances.
222.5 Policy and Guidance
During FY87, EPA issued seven policy and guidance documents to guide removal
program actions:
• Interim final guidance on State-lead removal actions
(Guidance for State-Lead Removal Actions, OSWER Directive
#9375.1-4-W, July 10, 1987). This guidance sets forth the
policy and procedures for awarding to States the authority
and funds necessary to lead a CERCLA-funded removal action.
The guidance is intended to provide EPA Regions with a new
management tool for handling their workload and will serve
as a mechanism for the further sharing of program
responsibilities via cooperative agreements with States.
20
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Under this program, States may lead all, or part of,
non-time-critical removal actions at NPL and non-NPL sites.
• Interim guidance specifying criteria and procedures for use
of the consistency exemption provided in CERCLA section
104(c), which allows a removal action to continue beyond the
$2,000,000, 12-month statutory limits if continued response
action is "otherwise appropriate and consistent with the
remedial action to be taken" (April 1987).
• Interim guidance on meeting the requirement of CERCLA section
104 that removals contribute to efficient performance of
long-term remedial action (April 1987).
• Interim final guidance regarding new drinking water action
levels. including a new decision model to determine whether
conditions at a site warrant removal action (October 1987).
• Guidance summarizing the land disposal restrictions under
Resource Conservation and Recovery Act (RCRA) section 3004
for the remedial program, and addressing the treatment of
Superfund removal wastes prior to land disposal (August
1987).
• Draft guidance on the use of alternative technologies in
remedial response --to encourage and facilitate the use of
alternatives to land disposal in the conduct of removal
actions (May 1987).
• Draft guidance on engineering evaluation/cost analyses. which
are performed to assess alternative removal actions in terms
of their appropriateness, feasibility, and cost effectiveness
(June 1987).
223 Status of Removal Activities in Fiscal Year 1987 Compared with 1981-86
Since the beginning of the Superfund program, the number of completed
removals has jumped from 18 in FY81 to a high of 201 in FY84. In FY87, EPA
completed 195 removal actions. A several-month delay in receiving the 1987
appropriation caused a reduction of the number of new starts and completed
removals (see Exhibit 2.2-2).
The type of completed removals has varied over time (see Exhibit 2.2-3).
In FY84, 63 (31 percent) of all Fund-financed removals occurred at inactive waste
management facilities. During FY87, 37 (19 percent) of all removals occurred at
inactive waste management facilities. Transportation-related removals have
dropped from 7 (3.5 percent) of all removals in FY84 to zero in FY87. Forty-
eight of the FY84 and 53 of the FY87 removals were in response to midnight
dumping.

23 The Remedial Program
23.1 Overview
A "remedial action" is a longer-term cleanup action intended to address
non-emergency situations and problems more complex than those that can be
addressed by removal actions. The Remedial Program consists of activities that
fall into three categories or phases: (1) the pre-remedial phase, In which the
extent of contamination at a site is assessed and those sites that represent the
highest priority for cleanup are identified; (2) the remedial action phase, in
which the remedy is designed and implemented; and (3) the operation and
maintenance phase, in which site upkeep and monitoring activities occur with the
remedy in place. The steps in the three phases of the program are described in
more detail below.
EPA's enforcement program plays an important role in maximizing Superfund
site cleanups, particularly in the remedial program context. The enforcement
program has two major components: negotiating voluntary settlements with
potentially responsible parties (PRPs) and taking enforcement actions against
PRPs. A fundamental goal of the enforcement program is to facilitate voluntary
settlements with PRPs. When settlement negotiations do not result in agreement,
EPA has two alternative courses of action. The Agency may take an enforcement
action to compel private party cleanup, or it may use Superfund money to finance
a government action and seek recovery of such costs from PRPs throug^h the courts.
SARA strengthened the enforcement program by codifying the existing CERCLA
settlement policy, establishing new authorities and procedures that, facilitate
private-party and Fund cleanups, and adding new authorities for imposing civil
and criminal penalties for failure to comply with the statutory provisions of
CERCLA that pertain to notification and reporting.
232 Inventory of Hazardous Substance Releases
EPA's CERCLA Information System (CERCLIS) includes a national inventory of
all hazardous waste sites potentially appropriate for listing on the NPL. Sites
are proposed for inclusion on the NPL as a result of citizen's petitions, an
incident at the site, or observation by Federal, State, or local officials.
Progress in Fiscal Year 1987
From FY80 through FY86, the number of sites included in CERCLIS grew from
8,000 to 25,194. At the end of FY87, 27,571 sites were inventoried, an increase
of 2,377 sites from October 1986. The annual number of sites in the inventory
from FY80 through FY87 is shown in Exhibit 2.3-1.
233 Preliminary Assessments
For each site in the inventory, EPA uses existing information to evaluate
the magnitude of the potential hazard at a site, identify the source and the
nature of the release, and identify any potentially responsible parties. Based
on the results of this preliminary assessment (PA), EPA determines if the site
merits further investigation. The PA does not normally include a site visit or

sampling. CERCLA section 105(d) specifies that any individual may petition EPA
to perform a PA and that EPA has up to one year to respond to the petition.
Progress in Fiscal Year 1987
Between FY80 and the end of FY87, 24,185 PAs were conducted; 4,001 PAs were
completed in FY87. The annual number of PAs conducted from FY80 through FY87 are
shown in Exhibit 2.3-1.
EPA met the CERCLA section 116 goal for completing PAs by January 1, 1988,
at those sites in CERCLIS as of October 17, 1986. The Agency also developed a
strategy in FY87 to modify the PA to identify more effectively those sites that
require site inspections (Sis). This strategy includes increasing the level of
effort for an average PA from 50 hours to approximately 75 hours to include
activities such as off-site reconnaissance, and the application of technical
evaluation criteria, professional judgment, and other technical factors for
assigning priority to sites needing Sis. Revisions to the guidance on conducting
PAs were made in FY87 to incorporate this strategy. The new PA guidance will be
released to Regions in the second quarter of FY88.
EPA expects that it can meet the requirements of CERCLA section 105(d) for
completing PA petitions within 12 months of their receipt and has developed
guidance on this requirement. EPA Regional offices report fewer than 20 PA
petitions were received during FY87.
23.4 Site Inspections
Site Inspections (Sis) are performed at sites where PAs indicate that
additional studies are warranted to evaluate potential hazards. On average, in
a given year, approximately 80 percent of PAs have indicated the need for an SI.
The SI consists of a visual L 'spection of the site and usually includes
collection and chemical analysis of a limited number of samples of environmental
media, e.g., soil, surface water, or ground water. There are several major
purposes for a SI: (1) to determine which releases pose no current or potential
threat to public health and the environment; (2) to determine if there is any
immediate threat to persons living or working near the release that might
necessitate an immediate removal action; and (3) to collect data, where
appropriate, to determine whether the site should be included on the NPL.
Progress in Fiscal Year 1987
Between FY80 and the end of FY87, 7,785 Sis were completed, with 1,343
completed in FY87 alone. The annual number of Sis conducted from FY80 through
FY87 is shown in Exhibit 2.3-1.
Under section 116, Sis (where warranted) are to be conducted by January
1989 for all sites in CERCLIS as of October 17, 1986. Although the Agency does
not believe it will be able to achieve this goal, guidance was developed in FY87
to enable the Agency to devote more resources to those sites most likely to be
proposed for the NPL. The guidance also includes details on new aspects of the
26
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
SI necessary to support the revised HRS that the Agency is proposing. The
revised guidance will be sent to the Regions in FY88.
23.5 Hazard Ranking System
The Hazard Ranking System (HRS) was designed to be a screening tool that
would allow EPA to rank sites quickly using data and information from the SI.
The current HRS score is a reflection of a site's potential to cause harm to
human health or the environment, as a result of the migration of hazardous
substances through ground water, surface water, or air. The overall HRS score
is a composite of separate scores for each of these contaminant migration routes.
The score for each route is obtained by assigning numerical values (according to
prescribed guidelines) to a set of factors that characterize the potential of the
release to cause harm. Sites with HRS scores of 28.50 or greater are eligible
for inclusion on the NPL. The 28.50 threshold value was initially chosen to
yield an NPL of at least 400 sites, as originally required by CERCLA, not because
it represents any threshold in the significance of the risks presented by sites.
EPA is reviewing the effect of this threshold, and may change it as a result of
the revisions that are now being made to the HRS methodology.
CERCLA, as amended by SARA, mandates that EPA1s revision of the HRS should
be guided by certain specific criteria. Section 105 requires EPA to amend the
HRS to ensure "to the maximum extent feasible, that the HRS accurately assesses
the relative degree of risk to human health and the environment posed by sites
and facilities subject to review." Section 105 also directed EPA to consider a
number of specific factors in its review of the HRS: the effect that
contamination of surface water has on the use of that water for drinking and
recreational purposes and the threat that contamination poses to the human food
chain and to ambient air. Section 118 directs EPA to assign a high priority to
facilities whose releases have led to the closing of drinking water wells or to
contamination of a principal drinking water supply. Section 125 requires EPA to
assess a number of factors in relation to the scoring of sites containing fly ash
wastes.
Progress in Fiscal Year 1987
In FY87, the Agency began revising the HRS to comply with CERCLA
requirements. The revised HRS will be proposed in early FY89. To facilitate
the revision process, an HRS revisions workgroup was established and met monthly
during most of the fiscal year. A testing program was implemented to evaluate
sites according to the revised HRS and three other site evaluation systems. EPA
also convened a site-ranking panel to evaluate and rank 20 sites according to
their perceived risk levels. This exercise was conducted to obtain expert
judgments to serve as the baseline with which to compare site evaluation models
and to gain a better understanding of the relative weights that should be
assigned to certain factors. The workgroup also prepared an economic impact
analysis of the proposed revisions to the HRS, and planned procedures for the
field testing of the revised HRS that EPA will conduct in FY88.

Progress Toward Implementing Superfund: Fiscal Year 1987
23.6 Listing on the National Priorities List
The main purpose of the National Priorities List (NPL) is to identify sites
that appear to present a significant risk to public health or the environment.
The National Contingency Plan (NCP) establishes that a site must be placed on the
NPL before it can undergo Fund-financed remedial action. The NPL does not,
however, determine priorities for removal actions; EPA may take removal actions
at any site, whether listed or not, if the site meets the criteria in section
300.65(b) of the 1985 NCP. Likewise, EPA may take enforcement actions under
CERCLA against PRPs regardless of whether a site is on the NPL. As a practical
matter, however, the focus of EPA's enforcement actions has been on NPL sites.
EPA follows the Administrative Procedure Act (APA) rulemaking procedures
to add sites to the NPL. These procedures involve proposing sites in the Federal
Register, soliciting comments on the proposals, and publishing a list of sites
ultimately chosen for inclusion on the NPL in the Federal Register.
Progress in Fiscal Year 1987
At the end of FY86, 703 sites were listed on the NPL and an additional 184
sites had been proposed for inclusion. In January 1987, EPA proposed 64 sites
for inclusion on the NPL. The proposed update included one Federal facility site
and sites located in 24 of the 50 States, the District of Columbia, and 6
territories. In July 1987, 99 sites (including 32 Federal facilities) were
added, bringing the total number of sites on the NPL to 802, with an additional
149 sites proposed for inclusion.
Of the States and Territories, eight had no sites listed on the NPL as of
July 1987: Alaska, American Samoa, the Commonwealth of the Northern Mariana
Islands, the District of Columbia, Hawaii, Nevada, the Trust Territory of the
Pacific Islands, and the Virgin Islands. New Jersey had the largest number of
listed sites (96), followed by New York (63), Pennsylvania (61), Michigan (58),
and California (48). The map in Exhibit 2.3-2 shows the location of all NPL
sites. Exhibit 2.3-3 shows the number of listed Federal and non-Federal NPL
sites and proposed sites in each State, as of July 1987. The number of sites
that have been added to the NPL each year from FY83 through FY87 is shown in
Exhibit 2.3-4. During FY87, the Agency also began work on Update 7 and, on June
24, 1988, proposed 229 new sites, including 14 Federal sites, for NPL listing (53
FR 23988).
23.7 Remedial Investigation and Feasibility Study
During the remedial investigation (RI), data are collected on all aspects
of the site, including the geologic and hydrologic characteristics of the site,
the nature of the on-site contaminants, and the characteristics and proximity of
the population near the site. Numerous samples of air, ground water, surface
water, soil, and contaminants are analyzed. A Superfund Public Health Assessment
based on these data determines the risks posed to human health and the
environment by the site contamination.

The feasibility study (FS) (often conducted concurrently with the RI) is
conducted to analyze alternative approaches that can be used to clean up a site.
Treatment technologies and non-treatment technologies that meet overall cleanup
objectives also are identified. The alternatives analyzed in the FS are
developed by screening the universe of potentially applicable technologies and
process options. By using readily available information on contaminant types and
concentrations and site conditions from the RI site characterization,
technologies and process options that clearly are not appropriate are screened
out.
Each alternative in the FS is evaluated with respect to the following nine
criteria. These criteria fall into three groups: threshold criteria that every
remedy must meet (1-2); primary balancing criteria that are used to weigh
tradeoffs among remedies (3-7); and modifying criteria that are considered after
public comment has been formally received (8-9).
(1) Overall protection of human health and the environment;
32
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
(2) Compliance with applicable or relevant and appropriate
requirements;
(3) Long-term effectiveness and permanence;
(4) Reduction of toxicity, mobility, or volume;
(5) Short-term effectiveness;
(6) Feasibility;
(7) Cost;
(8) State acceptance; and
(9) Community acceptance.
The results of this analysis provide the rationale for selecting a final remedy
that provides the best balance among the inevitable evaluation criteria trade-
offs.
Treatability studies determine the relative effectiveness of treatment
technologies that are identified as possibilities for the site. The results of
treatability studies also are used as bases for developing new technologies and
helping EPA meet the new statutory preference in CERCLA for remedies that use
treatment to reduce the volume, toxicity, or mobility of hazardous substances at
a site or operable unit within a site.
CERCLA section 104(a)(l) allows PRPs to conduct an RI/FSs, provided the
RI/FSs meet EPA's standards. The lead agency oversees the process to ensure
that the RI/FS is adequate for identifying an appropriate remedy and that it
will meet all relevant requirements. In the event of a PRP-conducted RI/FS, the
Agency develops an oversight plan that includes a schedule for oversight
activities. Generally, activities include reviewing project plans and work
products, overseeing the conduct of field activities, and meeting with PRPs.
Progress in Fiscal Year 1987
The SARA amendments to CERCLA include a number of provisions affecting the
selection of remedies at Superfund sites. EPA sent to the Regions late in
December 1986 and in July 1987 interim guidance on developing and selecting
remedies that comply with CERCLA provisions. EPA also sent to Regional personnel
in July 1987 interim guidance on compliance with applicable or relevant and
appropriate requirements. These interim guidance documents will be superseded
by final guidance documents that are scheduled for distribution to the Regions
in FY88.
The Agency took a number of actions in FY87 to improve the efficiency of
the RI/FS process and to incorporate changes to the RI/FS process in compliance
33
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
with CERCLA requirements. The following two major project management support
activities were initiated in FY87:
• The Alternative Remedial Contracts Strategy (ARCS); and
• The RI/FS improvements initiative.
Key components of ARCS include promoting continuity of performance from
RI/FS to construction management, increasing the level of competition for
contract awards, developing incentives to promote superior performance, and
facilitating the delegation of contract management to the Regions. The ARCS
concept was fully developed and procurement actions were initiated In two EPA
Regions. More details on the ARCS program are provided in Chapter 6 of this
Report.
An RI/FS improvements strategy was forwarded to Regional personnel in July
1987. The strategy includes several initiatives aimed at improving performance
on RI/FS projects and proposes implementation strategies for improving project
performance, while concurrently streamlining the RI/FS schedule. The strategy
is intended to be integrated with concepts from the Data Quality Objectives
guidance, the Compendium of Field Standard Operation Procedures, and the guides
for remedial project managers (RPMs).
The initiative attempts to provide a realistic strategy for implementing a
phased RI/FS that would facilitate compliance with statutory objectives without
requiring major changes to the remedial program. This RI/FS improvements effort
has three main objectives: to limit project planning activities to a 3-month
period following project initiation, with the ultimate goal of reducing the
overall RI/FS process to an 18-month schedule; to reduce overall costs; and to
improve the technical quality of RI/FSs.
Just after the close of FY87, EPA issued interim guidance that set forth
its policy and procedures for PRP participation in RI/FS preparation. EPA plans
to issue guidance that will identify the procedures to be followed by RPMs and
PRPs to properly initiate, control, and monitor PRP conducted RI/FSs.
In FY87, the Agency achieved its targeted goal for RI/FS starts. A total
of 183 RI/FSs were started: 127 Fund-financed RI/FSs and 56 PRP-financed RI/FSs.
Exhibit 2.3-5 shows that 76 of the Fund-financed RI/FSs were first starts; the
remaining 51 were subsequent starts. Forty-seven of the PRP-financed RI/FSs in
FY87 were first starts and nine were subsequent starts. Exhibit 2.3-6 shows the
annual number of RI/FS starts from FY80 through FY87. At the end of FY86, over
600 RI/FSs had been started. Under CERCLA section 116 goals, an additional 275
RI/FSs are to begin by October 1989.
Section 301(h)(l)(A) requires that summaries of each FS conducted during a
fiscal year be submitted to Congress annually. EPA treats records of decision
(RODs) as essentially equivalent to FS summaries. The FS summaries for this
Report, therefore, are based on RODs signed during FY87 and include information
on the major contaminants of concern at a site, the remedial alternatives

considered, and the selected remedy. Appendix C contains the FS summaries for
FY87.
23.8 Record of Decision/Selection of Remedy
The decisionmaking process that culminates in the selection of the remedy
for a site is a multi-step process. The alternatives analyzed in the FS are
developed by screening the universe of potentially applicable technologies and
process options. By using readily available information on contaminant types
and concentrations and site conditions from the RI site characterization,
technologies and process options that clearly are not appropriate are screened
out. Each remaining alternative is evaluated with respect to nine criteria
developed to address the statutory requirements and goals. Based on this
evaluation, the Regional Administrator or Assistant Administrator, in
consultation with relevant State personnel, selects the remedy for a site.
After a remedy is selected, a ROD is prepared. The ROD is a decision
document that identifies the selected remedy from a range of possible remedies
identified in the FS. The centerpiece of the administrative record, the ROD is
the document by which a court may judge the soundness of the Agency's decisions
about appropriate remedial action for a site.
Because the ROD has an important legal and technical role, it must contain
an accurate and complete summary of the site. The ROD, therefore, includes an
assessment of the threat posed by the site, a description of the remedy, a clear
justification for the remedy selected for a site, and a description of the
relative advantages and disadvantages of each alternative considered. The ROD
also contains a brief description of how the selected remedy satisfies the
statutory requirements of CERCLA section 121. The selected remedy must:
• Be protective of human health and the environment;
• Attain applicable or relevant and appropriate requirements
(ARARs) (or provide grounds for invoking a waiver);
• Be cost-effective;
• Use permanent solutions and alternative treatment technologies
or resource recovery technologies to the maximum extent
practicable; and
• Address whether the preference for treatment that reduces
toxicity, mobility, or volume as a principal element is
satisfied, or provide an explanation as to why it is not
satisfied.
Progress in Fiscal Year 1987
In June and July 1987, EPA sponsored three ROD workshops around the country
to advise RPMs on how to prepare FY87 RODs to ensure compliance with CERCLA. The
interim guidance on remedy selection issued in July also included information on
37
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
new components of the ROD required by CERCLA. This interim guidance explains the
nine key criteria to be considered in evaluating and comparing remedial
alternatives and the statutory findings about the selected remedy that must be
included in the RODs.
The Agency also began to revise the ROD guidance in FY87 to incorporate
provisions added to CERCLA by SARA and six years of program experience. The
draft guidance, now in progress, includes procedures to follow in developing the
proposed plan, a new document for promoting public participation required by
CERCLA section 117, and also presents new procedural processes designed to
increase State involvement in remedial decisionmaking. Finally, the guidance
discusses formats for presenting information in the ROD and procedures for the
ROD development process.
Summary of Fiscal Year 1987 Selected Remedies
The 75 RODs signed in FY87 represent approximately 90 percent of the goal
for the fiscal year; 58 were for first-start actions and 17 were for subsequent
starts (Exhibit 2.3-5). Exhibit 2.3-6 shows the annual number of RODs signed,
both for Fund-financed and potentially responsible-party-financed remedial action
through FY87.
Remedies selected in RODs can be divided into three categories: (1) source-
control remedies that use treatment as a principal component (e.g., incineration,
stabilization, solidification, chemical fixation, and biodegradation); (2)
source-control remedies that use containment as a principal component (e.g., on-
site or off-site landfill disposal and soil capping); and (3) non-source control
remedies (including no-action remedies, or those that address only ground water
or provide alternative water supplies).
To address the various types and sources of contamination at a site, the
ROD often involves more than one remedial component. Treatment-based source-
control remedies also may use containment technologies. For example, the ash
from an incinerator may be disposed of in an off-site landfill. In addition,
remedies classified in the containment-based and treatment-based source-control
categories also may have ground-water components. For example, a landfill remedy
may have a ground-water component for pumping and treating an aquifer.
The 75 RODs signed in FY87 involve a total of 119 remedial components that
are summarized in Exhibit 2.3-7. Thirty-two of these remedial components will
employ at least one type of treatment that will permanently and significantly
reduce the volume, toxicity, or mobility of the hazardous substances, pollutants,
and contaminants at a site: 13 will employ thermal destruction; 7
solidification; 2 stabilization; 3 aeration; 2 soil washing and flushing; 1
biodegradation; and 4 will employ other treatments.
Thirty-five remedies involve containment components to address non-residual
waste. On-site containment is involved in 24 remedies; off-site containment in
three; and temporary storage in eight. Ground-water pump and treatment actions
are included in 32 of the selected remedies. Finally, thirteen remedies provide
for alternative water supplies, and seven recommend no further action.

Progress Toward Implementing Superfund: Fiscal Year 1987
A completed RI/FS sometimes results in a ROD recommendation that "no further
action" is required to protect human health and the environment for one or more
operable units, even though the HRS score for the site indicated a site response
was warranted. There may be several possible reasons for such an outcome. The
HRS, as a general screening tool, uses a limited data set, while an RI/FS
collects and generates much more data to more completely characterize the threat.
Alternatively, a previous removal action at the site, or the completion of a
previous operable unit, may reduce the threat so that further response action is
unwarranted.
CERCLA section 121 requires that permanent solutions and alternative
treatment technologies be used at Superfund sites to the maximum extent
practicable. In addition, SARA added a statutory preference for remedies that
use treatment as a principal element to reduce the toxicity, mobility, or volume
of contaminants. The use of treatment-based source control remedies has been
increasing steadily over the history of the Superfund program. Exhibit 2.3-8
illustrates historical data on the use of treatment- and containment-based
remedies.
23.9 Remedial Design/Remedial Action
The selected remedy for a site is refined and specified in the remedial
design (RD) phase of the process. Once designed, the project is let for bids
and the selected contractor implements the project. At Fund-financed sites, EPA
funds 90 percent of the costs of constructing the selected remedy, including on-
site or off-site treatment to restore ground-water or surface-water quality for
up to ten years. At sites where the State or a political subdivision was
responsible for operation of the facility, EPA's contribution to the cost of
construction may be 50 percent or less.
Progress in Fiscal Year 1987
As of October 1986, 77 Fund-financed remedial design projects and 54 Fund-
financed remedial actions had been started. An additional 39 remedial design
projects and 27 remedial actions were started by PRPs over the same period. In
FY87, another 70 Fund-financed remedial design projects and 35 remedial actions
were started. Exhibit 2.3-9 shows that 57 of the Fund-financed remedial designs
and 25 of the remedial actions were first starts. Potentially responsible
parties started 24 remedial design projects and 19 remedial actions in FY87.
Nineteen of the PRP-financed remedial design projects and 16 of the PRP-financed
remedial actions were first starts. Sixty-eight administrative orders for
remedial action also were issued. Exhibit 2.3-10 shows the annual number of
Fund-financed and PRP-financed remedial design projects and remedial actions
(RAs) started from FY80 through FY87.
EPA also laid the groundwork for future increases in the design and
construction program. In this effort, Design and Construction Management
Workshops were held for Regional and State personnel. Revisions to contracting
procedures (such as the ARCS system discussed in Chapter 5 of this Report) were
made to improve design and construction program efficiency. EPA also worked with
the U.S. Army Corps of Engineers and the Department of the Interior, Bureau of

23.10 Operation and Maintenance
As of October 1987, a total of 12 sites had entered the operation and
maintenance (O&M) phase. Five of these sites entered the O&M phase in FY87.
O&M commences at a site after construction of the remedial action is completed.
O&M activities may include collection and treatment of ground water or leachate,
maintenance of water monitoring units, and overall site upkeep. For Fund-
financed actions, the Fund pays up to 90 percent of the costs of such activities
for the first year after an action is implemented to ensure that the remedy is
operational. The State pays the remaining 10 percent. At sites where a State
or political subdivision was responsible for operation of the facility, EPA's
contribution to the cost of operation and maintenance may be 50 percent or less.
After the first year, however, all O&M costs are paid by States.
23.11 Deletion of Facilities
The Agency has established procedures for deleting from the National
Priorities List those sites where conditions no longer threaten human health and
the environment. After remedial work is completed at the site, a site may be
deleted following public comment, review by EPA Regional and Headquarters staff,

and State concurrence. EPA then publishes the deletion decision in the Federal
Register. Sites deleted from the NPL remain eligible for Fund-financed remedial
action should conditions at the site warrant such action.
A notice of intent to delete three sites was published in the Federal Register
in September 1987. As of the end of FY87, a total of thirteen sites had been
deleted from the NPL, eight in FY86 and five in FY82.
23.12 State Assurance of Capacity
Section 104(c)(9) of CERCLA requires that a State assure the Agency that
it has sufficient capacity for hazardous waste treatment or disposal for a period
of 20 years following the date on which EPA and the State enter a contract or
cooperative agreement. For Fund-financed remedial actions, assurances must be
made by October 1989 or Superfund response action funding may be withheld. In
FY87, EPA awarded a grant for $1,200,000 to the National Governors' Association
to develop State-recommended guidance on this issue by November 1988. The
Association's recommendations are expected to serve as the basis for EPA's final
guidance on State capacity assurance.
23.13 Additional Enforcement Activities
The enforcement program accomplishments discussed thus far in this chapter
are complemented by significant additional work finalized since the passage of
SARA and other ongoing efforts.
23.13.1 Negotiated Settlements
A fundamental goal of the enforcement program is to negotiate voluntary
settlements on cleanup responsibilities as early as possible. EPA, in FY87,
negotiated a significant number of settlements related to cleanup activities:
RI/FS settlements worth $48,000,000 and RD and RA settlements worth $112,000,000.
Also, since the passage of SARA, EPA has continued to develop a number of new
mechanisms to facilitate and expedite the settlement process. These include
special notice letters, nonbinding allocations of responsibility (NBARs), mixed
funding settlements, de minimis settlements, covenants not to sue, and arbitration.
Each of these mechanisms is discussed in turn below.
Progress in Fiscal Year 1987
In February 1987, EPA issued interim guidance on streamlining the settlement
decision process. The Agency has also issued guidelines for expediting the
settlement process. The guidance describes modifications that will strengthen
and streamline settlement decisionmaking efforts in the following arejas:
• Negotiation Preparation. EPA will strengthen its negotiating
position with a more comprehensive preparation period. The
Agency will undertake detailed PRP searches earlier in the
remedial process, conduct more complete exchanges of
information, initiate discussions with PRPs at an earlier
44
-------
Progress Toward Implementing Super-fund: Fiscal Year 1987
date, and prepare a negotiation strategy and a draft
settlement document.
• Management Review of Settlement Decisions. EPA established
teams to conduct negotiations and raise issues to the
Regional Administrators and, where necessary, to the
Settlement Decision Committee (SDC). The SDC consists of the
Director of the Office of Waste Programs Enforcement
(Chairman), Associate Enforcement Counsel-Waste, Chief of the
Environmental Enforcement Section at the Department of
Justice, and two Regional representatives. While EPA
develops guidance material and gains experience with this
approach, the SDC will review and oversee certain settlement
issues. Regional Administrators will eventually assume broad
authority for negotiation decisions.
• Deadline Management. EPA recognizes that circumstances arise
requiring extension of negotiations beyond the 30-day
moratorium. Guidance discourages negotiation extensions, but
Regional Administrators may grant extensions of up to 30 days
when they believe settlement is imminent. Further extension
of RD/RA negotiation beyond the 30-day period may be approved
only by EPA Headquarters.
Notice Procedures
CERCLA promotes negotiations between EPA and private parties through the
use of notice letters. Notice letters inform PRPs of their potential liability,
initiate a continuing exchange of information, and provide an opportunity for
PRPs to enter into negotiations to conduct or finance response activities.
In the fourth quarter of FY 1987, 42 special notice letters were issued (31
RI/FS and 11 RA). On October 19, 1987, the Office of Waste Programs Enforcement
issued "Interim Guidance on Notice Letters, Negotiations, and Information
Exchange" (OSWER Directive Number 9834.10).
The notice procedure is a three-step process. General notice is issued to
PRPs early in the process of addressing a site, preferably when a site is
proposed for inclusion on the NPL. It informs PRPs of their potential liability
for future response costs, promotes information exchange, and initiates the
process of "informal" negotiations.
At its discretion, EPA may initiate the second step of the notice process
by issuing the RI/FS special notice. The RI/FS special notice is sent to a PRP
no later than 90 days prior to the scheduled start of the RI/FS. This procedure,
routinely followed by EPA, invokes a moratorium on EPA's RI/FS activities and
triggers a period of formal negotiation. The final step of the notice process,
the RA special notice, similarly begins a period of negotiation and invokes a
moratorium on the Agency's RA activities. For both RI/FS and RA special notices,
the moratoria provide private parties with the opportunity to develop and submit
a proposal to conduct or finance response activities.

Nonbinding Allocations of Responsibility
As mandated by CERCLA, EPA has developed NEAR guidelines. These interim
guidelines were published in the Federal Register on May 28, 1987 (52 FR 19919).
Nonbinding Allocations of Responsibility are notices sent to PRPs under the
authority of CERCLA section 122(e)(3) informing them of the percentage of total
response costs at a facility that EPA considers to be their responsibility.
Major factors considered in determining response cost allocations are the volume,
toxicity, and mobility of waste and the nature of the case against the different
parties. EPA will issue NBARs (normally during the RI/FS) at its discretion if
they are likely to promote settlement. NBARs are not a statement of harm or
causation nor are they admissible as evidence. After receiving an NBAR, PRPs may
offer to undertake or finance a cleanup; they are expected to determine the final
allocation toward settlement among themselves.
Mixed Funding
CERCLA section 122(b) provides explicit authority for mixed funding, which
is the use of both private and Fund resources to finance response actions at a
single site. Mixed funding results from the need for an expeditious cleanup.
EPA's evaluation involves determining both the most effective means of cleanup
and the most efficient use of the Agency's resources. The limited contribution
of waste by a PRP and financial weakness are two factors that may indicate the
appropriateness of mixed funding. Mixed funding is best used in situations
involving a small Fund share, and where there exists a strong case against
nonsettlors that enables EPA to recover its expenditures from other PRPs.
On March 14, 1988 (53 FR 8279), EPA issued guidance that discusses the
factors that are considered in determining whether mixed funding is appropriate
for a given site. Mixed funding can be accomplished through pre-authorized
claims against the Fund and through "cash outs" or "mixed work." EPA has
approved three preauthorized PRP settlements for response actions to date: 79
percent of $44,800,000 ($35,000,000), 75 percent of $3,000,000 ($2,250,000), and
66 percent of $10,000,000 ($6,600,000), and several others are under
consideration.
De Minimis Settlements
Section 122(g) authorizes EPA to enter into expedited settlements with de
minimis parties provided that the settlement is in the public interest and involves
a minor portion of the response costs at the facility. Two types of de minimis
parties are defined by this section: de minimis contributors (generators and
transporters) and de minimis landowners. A party may qualify as a de minimis
contributor when the amounts and toxicity of hazardous substances contributed by
that party are minimal in comparison to other hazardous substances at the
facility. A de minimis landowner is one who did not conduct or permit the
generation, transportation, storage, treatment, or disposal of any hazardous
substance at the facility. In addition, the landowner must not have contributed
to the release or threatened release at the facility.
46
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Parties qualifying for a de minimis settlement may be provided with a covenant
not to sue. Settlements may be embodied in a consent decree or administrative
order. Parties who enter settlements under this provision are entitled to
contribution protection.
In FY87, there was one de minimis settlement for a value of $340,000 at a site
requiring a $2,500,000 remedy and involving $5,500,000 of past costs. The Agency
issued guidance on settlements with de minimis waste contributors on June 19, 1987.
This guidance was published in the Federal Register at 52 FR 24333 (June 30, 1987).
The Agency is presently applying the guidance on de minimis contributor settlement
at several sites.
Covenants Not To Sue
Section 122(f)(l) authorizes EPA to issue a covenant not to sue to
responsible parties for any liability to the United States under CERCLA,
including future liability, resulting from a release or a threatened release
addressed by a remedial action. Such covenants can be used if: the covenant
is in the public interest; it would expedite the response; the settlor is in
full compliance with a consent decree under section 106 addressing the release
or threatened release; and EPA has approved the response action.
Interim guidance on the use of covenants not to sue, including a model
covenant, was issued on July 10, 1987 (52 FR 28038, July 27, 1987). This
guidance covers the implementation of the mandatory and discretionary provisions
of section 122(f) of CERCLA relating to use of covenants. When all necessary
conditions are met, EPA may provide a covenant not to sue, but the covenant may
not take effect until EPA certifies that the remedial action has been completed.
Arbitration
Section 122(h)(2) of CERCLA, as amended by SARA, authorizes the
Administrator, as well as the head of any other department or agency authorized
to undertake a response action under CERCLA, to use arbitration as a method of
settling section 107 cost recovery claims where the total response costs for the
facility concerned do not exceed $500,000, excluding interest. Arbitration may
be used in accordance with regulations promulgated by EPA, or other authorized
agencies or departments, after consultation with the Attorney General.
EPA has begun to develop a regulation that will establish and govern the
procedures by which EPA may use binding arbitration as a method of settling cost
recovery claims. The regulation will establish procedures for the referral of
claims for arbitration, selection and jurisdiction of the arbitrator, conduct of
the pre-hearing conference and arbitral hearing, rendering of the arbitral
decision, appeals from and enforcement of the arbitral decision, and fees.
23.132 Civil and Criminal Litigation
Section 103(a) requires a person in charge of a vessel or facility to notify
immediately the NRC as soon as he or she has knowledge of any release, other than
a federally permitted release, of a hazardous substance in an amount equal to or
47
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
greater than a reportable quantity. Criminal sanctions may be imposed for
failure to comply. The NRC must convey notification expeditiously to all
appropriate agencies, including the Governor of any affected State.
Section 103(b) establishes a notice and reporting requirement for the
storage, treatment, or disposal of hazardous substances. The notice must specify
the type and amount of hazardous substances found at the facility, and any known,
suspected, or likely releases of such substances from the facility. Knowing
failure to provide such notice could result in the imposition of criminal
sanctions. In addition, the violator will not be entitled to any limitation of
liability or to any defenses to liability set out in section 107 of the Act. It
is important to note, however, that notice is not required if the facility has
already been permitted or accorded interim status under Subtitle C of the
Resource Conservation and Recovery Act (RCRA).
Section 103(c) addresses the failure to notify EPA about an unpermitted
facility at which a hazardous substance is treated, stored, or disposed. Section
103(d) addresses destruction or concealment of records that the Act requires to
be maintained. Criminal sanctions may be imposed for failure to comply with the
requirements of these subsections.
SARA amended CERCLA enforcement authority by adding civil penalties and
strengthening the existing criminal penalties. SARA added Class I and Class II
administrative penalties under section 109 for non-notification concerning the
release of a hazardous substance in an amount equal to or greater than its RQ.
Past and Ongoing Criminal Enforcement Activities
Since FY 1983, the EPA's Office of Criminal Investigations, the National
Enforcement Investigations Center (NEIC), has conducted 183 investigations that
have been based in whole or in part on suspected violations of the criminal
provisions of CERCLA. Of these investigations, 136 are closed and 47 remain
active. To date, approximately 20 investigations have resulted in prosecutorial
action taken pursuant to CERCLA. These include two cases involving convictions
and one case involving reversal. An additional four investigations have inspired
criminal cases that remain open pending appeal or further prosecution. These 24
cases include counts for violations of section 103(b) and (c) of the Act.
Progress in Fiscal Year 1987
In August 1987, EPA developed interim guidance on imposing Class I and Class
II penalties for non-notification concerning releases of hazardous substances in
amounts equal to or greater than RQs. These procedures will amend the
Consolidated Rules of Practice at 40 CFR Part 22.
23.133 Enforcement Regulations, Policies, and Guidances
Since the passage of SARA, a number of regulations, policies, and guidances
have been issued or are near completion. These documents support both
enforcement and settlement efforts.
48
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Administrative Record
CERCLA section 113(k) requires EPA to establish an administrative record
for selecting a response action. Regulations allowing interested parties to
participate in the development of the administrative record must also be
promulgated. Use of the record achieves two goals:
• It allows for increased public participation in the selection
of the response action.
• It limits the scope of any judicial review to the available
record in any judicial action concerning the adequacy of
response action, thereby minimizing delay and reducing the
cost of litigation.
The Agency drafted proposed regulations on the administrative record in
conjunction with revisions to the NCP. The regulations are subpart I of the
proposed revised NCP. In May 1987, the Agency issued guidance on the use of the
administrative record in selecting CERCLA response actions. Several training
sessions, workshops, and Regional visits have been conducted to ensure adequate
compilation and maintenance of the administrative record. To date, most Regions
have compiled administrative records for their high-priority sites.
Indemnification of Response Action Contractors
CERCLA section 119 requires that EPA first publish guidance, and then
regulations, concerning EPA indemnification of Superfund Response Action
Contractors (RACs) working for EPA, States, or potentially responsible parties.
Section 119 also requires that EPA guidance be developed and that adequate
opportunity for public comment be provided. To assist with guidance development,
EPA has organized an internal Task Force, an external review panel consisting of
insurance and actuarial experts, and another external review panel consisting of
representatives of the RAG community.
The Task Force has distributed interim guidelines and interim
indemnification contract language to EPA contracting officers for use with EPA
contracts. Interim guidance has also been provided to the Regional Offices
concerning indemnification of RACs working for States and PRPs, as well as more
detailed guidance concerning indemnification of EPA contractors. Final guidance
is currently under development and will be proposed in the Federal Register for public
comment. Following the public comment period, final guidance will be published.
All EPA response action contracts containing indemnification clauses have
been modified to reflect the requirements of section 119. Pursuant to section
119, several RACs working for States at State-lead NPL sites have been offered
indemnification by EPA. To date, EPA has not offered indemnification to any
RACs working for PRPs.
49

Progress Toward Implementing Super-fund: Fiscal Year 1987
Supplementary Enforcement Directives
In addition to the key guidances of the enforcement program discussed above,
OSWER has issued a number of enforcement-related directives in FY 1987. These
directives serve to describe procedures of the enforcement mission and to amplify
CERCLA provisions related to enforcement.
Procedures pertaining to the early phase of an enforcement action are laid
out in directives that cover access to a site and provide guidelines for the PRP
search and off-site response. Other directives describe landowner liability,
limitations on cost recovery, and the reimbursement of abatement costs. A final
directive pertains to changing the status of a site from enforcement to Fund
lead.
2.4 Status of Active Remedial Investigations/Feasibility Studies and Remedial Actions
This section includes a summary status report for all RIs, FSs, and RAs in
progress as of September 30, 1987, the end of the fiscal year. The detail of
the status report, required by subparagraph (B), (C), and (F) of GEORGIA section
301(h)(l), is presented in Appendix D. At the end of FY87, remedial activities
were underway at 533 sites. There were 642 ongoing remedial projects: 548
RI/FSs, 15 FSs, and 79 RAs. The reference date used to determine the status of
the projects is January 1, 1987, which, EPA acknowledges, may not account for
all the time gained or lost in the life cycle of a given project. However, EPA
chose the date because it marked the first update for RI/FS and RA projects after
the hiatus between Superfund authorizations. Choosing an earlier date would have
included time lost due to circumstances beyond EPA's control.
To understand what the status report means, we have included the following
discussion of the EPA approach, based on operable units, to accounting for
cleanup activities at a Superfund site. At many Superfund sites, a number of
remedial activities* may be needed because, in addition to a discrete source of
contamination, soil, ground water, air, or surface water also may be
contaminated. Remedying this degree of contamination is often a complex task,
requiring health and environmental risk assessment and painstaking design of an
engineered solution.
Operable Units
To handle complex problems efficiently, the needed site work is often
divided into several distinct activities or "operable units" that take form at
the start of or during an RI/FS. One operable unit may begin and end at a
different point in time from another, depending on a variety of factors. Most
operable units are specific to a group of activities intended to mitigate some
part of the threat to human health or the environment posed by the site.
Investigations and studies done to determine the extent of a release,
although included in the statutory definition of removal activities Ln CERCLA
section 101(23) by reference to section 104(b), are commonly considered
components of the remedial program and are treated as such in this Report.
50
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
The first operable unit is referred to as the first start; operable units
that follow are referred to as subsequent starts. The first operable unit may
involve replacing a water supply; a second operable unit may control the spread
of contamination from an abandoned municipal waste landfill and the associated
plume of ground-water contaminants that is flowing toward a public water supply
wellfield.
The operable unit approach enables EPA to effectively set priorities for
site cleanup and manage the project overall. After the remedy for an operable
unit is selected in a ROD, the RD phase usually follows, and then construction
of the RA begins. Many events influence the progress of an operable unit through
the Superfund system. The more significant influences include:
(1) Changes in the entity primarily responsible for the project,
which can be EPA, a State, or a potentially responsible party
or parties;
(2) Changes in the number of operable units underway at a site;
operable units are sometimes consolidated or expanded due to
new information or changes in circumstances; and
(3) Complex contracting arrangements involving EPA, the States,
potentially responsible parties, and the availability of
response action contractors.
EPA's system for tracking the status of RI/FSs, FSs, and RAs, illustrated
in Appendix D, reflects the operable unit approach by including the RI/FSs, FSs,
and RAs for each operable unit at a site. Numbers illustrating project status
are presented in Exhibit 2.4-1; project totals by Region and State are
illustrated in Exhibit 2.4-2.
2.4.1 Status of Remedial Investigations and Feasibility Studies
Of the 563 combined RI/FS and FS projects, 48 (8.5 percent) were ahead of
schedule, and 148 (26.3 percent) were on schedule. Approximately 57 percent of
RI/FS and FS projects were behind schedule at the end of the fiscal year: 280
(49.7 percent) of the RI/FSs were 1 to 4 quarters behind schedule; 35 (6.2
percent) were 5 to 8 quarters behind; and 8 (1.4 percent) were more than 8
quarters behind. No estimates of completion for the remaining 44 (7.8 percent)
had been made prior to the estimates made at the end of the fiscal year. Thus,
there is no basis of comparison for these projects.
Project delays can be attributed to many factors including the hiatus in
program funding during the FY85-FY86 period; the necessity to complete complex
contracting arrangements before projects could begin; and a high level EPA
employee turnover. The Agency's goal is to complete an RI/FS and select a remedy
within 18 to 21 months. Historically, however, RI/FSs have taken 24 to 35 months
to complete.

Progress Toward Implementing Superfund: Fiscal Year 1987
RI/FS Initiatives
The Agency has initiated several activities directed specifically toward
acceleration of RI/FS projects. A key step, the RI/FS Improvement Initiative,
includes planning, priority-setting, use of operable units, and streamlining of
the RI/FS process. RI/FS streamlining focuses on tailoring the scope and detail
of the RI/FS to site conditions. The analysis of evaluation criteria and the
development of a range of remedial alternatives will be better suited to the
complexity of the problems at the site. Fewer alternatives will be developed for
sites with straight-forward problems, and clearly impractical alternatives will
not be studied in detail.
OERR revised RI/FS guidance to reflect the new emphasis and provisions of
CERCLA, incorporate aspects of new or revised guidance related to RI/FSs,
incorporate management initiatives designed to streamline the RI/FS process, and
take advantage of experience from previous RI/FS projects, where appropriate.
2.42 Status of Remedial Actions
Of the 79 ongoing RA projects, 13 (16.5 percent) were ahead of schedule;
24 (30.4 percent) were on schedule. A total of 31 (39.2 percent) RA projects
were behind schedule: 26 (32.9 percent) were 1 to 4 quarters behind schedule;
4 (5.1 percent) were 5 to 8 quarters behind; and 1 (1.3 percent) was more than
8 quarters behind. For the remaining 11 (13.9 percent), there were no prior
estimates of completion.
RA Initiatives
A key initiative is OSWER's Strategy for Management Oversight of the
Remedial Action Start Mandate. Although directed primarily toward satisfying
CERCLA's new mandate for RA starts, it also establishes a Headquarters-Regional
management plan that incorporates principles that will be applied throughout the
program to accelerate the response process. Using current Superfund
Comprehensive Accomplishments Plan (SCAP)/Strategic Planning and Management
System (SPMS) accountability systems, the Agency will focus attention on early
portions of project schedules to identify projects that could slip or issues
that could affect project schedules, such as State cost assurances, site access,
disposal capacity, or property acquisition. The program will also use the
upgraded CERCLIS and the Office of Enforcement and Compliance Monitoring (OECM)
docket to track the progress of each project and develop exception reports on
projects that are behind schedule. Appropriate assistance can then be provided
to keep projects on schedule.
Also, OERR is developing model design schedules based on Agency experience
with a variety of remedial alternatives. Model schedules will assist Remedial
Project Managers in preparing accurate site-specific schedules and action plans.
Another important step was the development of the project management concept
under which the program will emphasize the importance of involving only one
contractor in all phases of the response. OERR is implementing the single-
contractor concept through ARCS, which will award numerous remedial contracts
in a Region or group of Regions. ARCS will promote continuity of performance
55
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
from RI/FS through construction management, increase competition for remedial
contract awards, and facilitate the delegation of contract management to the
Regions. Regions will be able to pinpoint and assign additional work to
contractors doing quality work on schedule.
In addition, OERR is considering a construction management support program
that would make a construction management specialist available to assist the
Regions in planning and executing RDs and RAs. OERR is also negotiating with
the Corps of Engineers and the Bureau of Reclamation about their role in meeting
program objectives. Negotiations are focused on working closely with the Regions
and establishing faster contracting procedures for assigned RDs and RAs.
2.43 Initiatives to Meet Schedules
During FY87, the Agency developed a multiple-initiative strategy to
accelerate RI/FS and RA activities and meet schedules for RI/FS and RA initiation
and completion. The objectives of the strategy are to improve EPA's ability to
estimate the duration of projects, to complete projects on schedule, and to meet
the additional responsibilities imposed by amendments to CERCLA that require EPA
to begin 175 first-start RA projects by October 16, 1989, and an additional 200
by October 16, 1991.
Enforcement Initiatives
The enforcement program is working to expedite processes such as settlement
negotiations that may delay response actions. Negotiations will be tracked to
ensure compliance with guidance on streamlining the CERCLA settlement process.
Also, special notice guidance has been completed requiring that moratoria
imposition coincide with release of the FS and proposed plan in order to minimize
delays in remedy implementation after the ROD is signed.
Regional Initiatives
Regional initiatives include the insertion of schedules in all cooperative
agreements, interagency agreements, contracts, work assignments, and consent
decrees to ensure that EPA will meet scheduled targets. In addition, to avoid
slippage in the initiation of remedial construction, the Regions may subject
remedial designs to review for bidability, construetability, and operability.
2.5 Status of Facility Reviews Under CERCLA Section 121 (c)
Section 301(h)(l)(E) of CERCLA requires a report on the progress made in
reducing the number of facilities (or sites) subject to periodic review under
section 121(c) . In addition to satisfying the section 301(h)(l)(E) requirement,
this Report satisfies other and similar requirements in section 121(c) to report
to Congress: (1) a list of facilities for which such review is required; (2)
the results of all such reviews; and (3) any actions taken as a result of such
reviews. The available information on section 301(h)(l)(E) and section 121(c)
requirements is included in this Report, and will be augmented in subsequent
reports as section 121(c) implementation proceeds.

-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Section 121(c) of CERCLA requires a 5-year review of those sites at which
hazardous substances, pollutants, or contaminants remain at a site after remedial
action has been initiated. It is further stipulated that if the results of a
review indicate further action is necessary, the appropriate action should be
taken. The Agency proposed a policy, in the revisions to the NCP, for defining
the sites where reviews must be conducted and describing the purpose of the 5-
year reviews. The application of this policy (summarized in section 2.5.1) will
be affected by the progress made in implementing remedies that adhere to the
cleanup standards specified in section 121.
2.5.1 Facilities Subject to Review
Selected remedial actions permit hazardous substances, pollutants, or
contaminants to remain on site when they do not threaten human health or the
environment. However, if the concentration of contaminants left on site exceeds
established levels, EPA is proposing to conduct a facility review to ensure the
remedy continues to be protective of human health and the environment. This
approach is consistent with clean closure under the Resource Conservation and
Recovery Act. Reviews will be conducted at sites currently considered to have
"safe" levels of contaminants if and when standards defining protective levels
are changed such that these sites are considered to have "unsafe" levels of
contamination.
If a review shows that a remedy is no longer protective, additional actions
shall be taken to mitigate the threat. Sites will become subject to the review
process and enter the inventory upon completion of the remedial action. Sites
deleted from the NPL will still be eligible for review. Facility reviews are
not planned to be conducted at non-NPL sites where removal actions have been
undertaken.
Once EPA finalizes the policy for implementing section 121(c), operating
procedures will be established for:
• Tracking site status, including quantity of wastes remaining
on site, occurrence of releases, integrity of containment
or other remedial measures, and need for further remediation;
• Re-examining site status, including potential application
of newly developed treatment technologies, and procedures
to initiate new remedial action; and
• Collecting information on site status and reporting to EPA
managers and Congress.
Procedures also will be established for determining the progress made in
reducing the number of facilities subject to review under section 121(c).
Progress in this area will be a function of increases in selection of source-
control remedies that include treatment.

2,5.2 List of Facilities Subject to Review
Facilities potentially subject to review under section 121(c) are listed
in Exhibit 2.5-1. The list now includes sites that have been deleted from the
NPL. A review is being conducted to determine at which of these sites remaining
contaminants exceed health-based levels. EPA also will review sites at which
remedial action or operation and maintenance has started for possible inclusion
on the section 121(c) list.
2.6 The Cost Recovery Program Under CERCLA Section 107
During the fiscal year, EPA Regional offices referred 37 cost recovery cases
with a combined dollar value of $30,592,354 to EPA Headquarters. A total of
$18,866,000 was collected and deposited in the CERCLA Trust Fund. Exhibit 2.6-
1 illustrates the key results of the cost recovery program prior to and during
FY87, and also includes the number of actions referred to the Department of
Justice (DOJ), actions filed by DOJ, and the dollar amounts the actions
represent.
Through the end of FY87, EPA had initiated actions to recover $242,000,000
worth of costs incurred at 158 sites and had collected $48,598,000. Exhibit
2.6-2 illustrates the value of cost recovery settlements for each fiscal year.
During FY88, EPA expects to initiate 49 additional cost recovery actions worth
approximately $118,000,000.
EPA's object in the cost recovery program is to pursue reimbursement in
every case where there is a financially viable PRP. The liability imposed on
PRPs by CERCLA section 107 enables EPA to begin response action at a site without
waiting for the outcome of a legal action. In this way, the program allows
response action to go forward and conserves Superfund dollars.
During the pre-remedial investigation, parties identified as being
responsible for the threat posed by a site are given the opportunity to design,
construct, and fund cleanup action. The PRPs, which may include generators and
transporters of the hazardous substances involved in the release as well as
current and former owners or operators of the site, must agree to reimburse EPA
before the start of the RI/FS.
If PRPs initially refuse to pay for site cleanup, EPA can proceed with the
necessary response actions and subsequently sue the PRPs to recovery costs. EPA
can also, under CERCLA section 104, recover the costs of third-party oversight
activities, which are incurred when EPA contractors assist EPA in the oversight
of PRP cleanup activity. For example, EPA contractors may oversee field
activities, such as sampling. The Agency can sue PRPs or recover oversight costs
by administrative order or consent decree.

Progress Toward Implementing Superfund: Fiscal Year 1987
3.0 THE FEDERAL-STATE PARTNERSHIP IN IMPLEMENTING CERCLA
3.1 Overview
The original CERCLA enacted in 1980 provided for State involvement in
response activities by allowing EPA to enter into cooperative agreements (CAs)
with States to undertake Fund-financed response activities. CERCLA, as amended,
extended this opportunity to Indian Tribes and political subdivisions and
included enforcement in the definition of response.
EPA may enter into CAs with States or political subdivisions of States, or
Indian Tribes which: (1) allow a State to take the lead in response activities
at a single site or at several sites in the State; (2) allow EPA and the State
to take the lead for different response activities at a site or number of sites
in the State; and (3) provide funding for States to assist or support EPA-lead
response actions. In addition, EPA uses Superfund State contracts to gain
assurances regarding shares of response costs for which States are responsible,
and State operation and maintenance obligations at EPA-lead sites.
The Agency has developed guidance for entering into CAs with States that
enable the States to take the lead on Fund-financed pre-remedial response (PAs
and Sis), remedial response (RI/FSs, RDs and RAs), removals, and enforcement
activities. EPA has also developed guidance for CAs with political subdivisions.
CERCLA provides for Indian involvement in the Act's implementation by requiring
that Indian Tribes be treated substantially the same as States, and by
authorizing EPA to enter into CAs with Indian Tribes in order that they may take
the lead for CERCLA response.
Federal agreements with States to conduct remedial actions also have been
affected by CERCLA section 104(c)(9). Beginning in 1989, a State must assure
EPA that adequate capacity exists for the destruction, treatment, or secure
dispostion of all hazardous waste expected to be generated within the State.
The assurance must be made for the 20-year period following the signing of a CA
with a State; EPA provides this assurance for agreements involving Indian Tribes.
SARA emphasizes the CERCLA provisions concerning State involvement by
requiring "substantial and meaningful" State involvement in all phases of
response activities. Specifically, the passage of SARA required the Agency to
undertake several initiatives, including promulgation of procedures for State
involvement under CERCLA section 121(f), and the identification of applicable
or relevant and appropriate requirements (ARARs) in the Federal-State
partnership.
Finally, CERCLA requires that EPA develop and implement procedures to
adequately notify concerned State and local officials of limitations on the
payment of claims for CERCLA response costs.
62
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
3.2 Progress in Fiscal Year 1987
EPA's FY87 achievements in the area of State participation in Superfund
consisted of the planning and implementation of CERCLA-mandated measures, and
the enhancement of these measures by several additional EPA initiatives.
32.1 Oversight Policy
Increased State involvement in hazardous substances response will require,
in some instances, changes in EPA's oversight role and more flexibility in Agency
oversight of State implementation of CERCLA and State-lead activities. The
Agency is developing a comprehensive oversight policy for State implementation
of CERCLA and detailed guidance on how to apply this policy. The policy will
address the following components: (1) working with States to reduce or eliminate
duplication of Federal and State efforts; (2) identifying weaknesses and
strengths in State efforts; (3) assisting States in improving their capabilities;
(4) helping States increase their participation in Superfund responses; (5)
improving State environmental programs to focus efforts on tangible cleanup
results, rather than on financial and accounting work; and (6) ensuring that the
oversight effort corresponds to a State's capability, experience, and role in the
particular response activity.
3.2.2 Superfund Memorandum of Agreement
EPA also encourages State involvement beyond the minimum statutory and
regulatory requirements through a Superfund Memorandum of Agreement (SMOA). The
SMOA is an agreement between the EPA Regional Administrator and the head of the
relevant State agency that defines the State's role and EPA's role when each one
acts as the lead or support agency at a hazardous waste site.
The SMOA spells out processes for Federal-State coordination on pre-
remedial, remedial, and enforcement response activities, and on certain aspects
of removal activities. The SMOA clarifies roles and expectations, thereby
improving coordination and reducing misunderstandings. The SMOA provides the
opportunity for all States, as their individual capabilities permit, to become
more active and undertake greater responsibility in response activities. The
SMOA establishes an annual consultation process in which EPA and the State agency
identify the lead agency for various response activities, set priorities, and
provide for State involvement in long-range planning. Individual CAs or multi-
site CAs combine with the SMOA to make the Federal-State partnership as flexible
as possible.
323 State Involvement Regulations
Section 121(f) of CERCLA, which was added by SARA, requires that the Agency
promulgate regulations providing States with an opportunity for "substantial and
meaningful" participation in all aspects of remedial response. CERCLA also
establishes minimum statutory requirements for State involvement.
The Agency has developed proposed revisions to the NCP that include CERCLA-
mandated regulations on State participation in the implementation of the Act.
Under this proposal, Subpart F of the proposed revised NCP addresses all issues
63
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
related to State involvement in hazardous substance response. Subpart F
delineates State involvement in pre-remedial, remedial, and enforcement response
in the manner required by CERCLA section 121(f)(l). The proposed NCP also
defines EPA involvement as a support agency in State-lead response activities.
The proposed revisions to the NCP were published in November 1988.
The Agency provided for significant State participation in the development
of the proposed revisions to the NCP through a State Issues Reauthorization
Workgroup and through State involvement in the NCP Workgroup and other Superfund
Implementation Workgroups. To facilitate State participation in these
Workgroups, EPA provided a grant to the National Governors' Association (NGA)
in 1987 to work closely with the State representatives on the workgroups, and
also with the Association of State and Territorial Solid Waste Management
Officials (ASTSWMO), and the National Association of Attorneys General (NAAG)
to assure that all State views were received.
As part of this process, the NGA staff liaison has: (1) coordinated the
various State concerns and conveyed these concerns to EPA; (2) provided
information on workgroup efforts to ASTSWMO and NAAG for distribution to their
members; (3) ensured that State representatives received materials and advance
notice of workgroup meetings; (4) coordinated the selection of State
representatives to serve on newly formed Superfund workgroups; and (5) served
as a State liaison between the EPA project officer, workgroup chairs, and other
appropriate EPA staff and the States. EPA has provided NGA with a second grant
to continue this work through FY88 and FY89.
CERCLA, as amended, requires EPA to attain State ARARs that are promulgated
and are more stringent than Federal ARARs. Subpart F of the proposed revisions
to the NCP requires Federal-State interaction on identification of ARARs and
will establish an appropriate process. In addition, the Agency is developing
procedural guidance for implementing this requirement that will outline the
procedures and roles of States and EPA when acting as lead or support agency.
The Agency is also developing specific guidance on Federal-State
relationship in identifying ARARs to determine how to address "more stringent"
State standards, particularly under Federal environmental statutes where States
either have delegation or are otherwise authorized to administer the Federal
programs. In addition, the Agency is developing .guidance on how the Agency will
address unique State requirements, such as bans on landfill disposal, siting
requirements, or non-degradation standards.
The Agency includes requirements for State credits toward State cost-share
obligations in the revised NCP. The Agency has prepared interim guidance on
State credits and is improving Agency financial management systems to ensure
proper management and application of State credits.
The Agency is also providing for State involvement in the selection of
remedy process that will depend upon a State's capability and experience, the
EPA-State relationship, and site-specific characteristics. The Agency is
developing comprehensive guidance on the State remedy selection process for
State-lead sites, including the timing and procedures associated with the
64
-------
Progress Toward Implementing Super-fund: Fiscal Year 1987
process, and criteria to determine State eligibility to participate in the
process.
CERCLA and the State involvement regulations that are part of the proposed
changes to the NCP significantly expand State involvement in the remedial
process. In addition to those elements discussed above, the remedial process
includes an annual planning meeting at which the EPA Region and the State
identify the lead agency for a site-specific response, establish priorities and
schedules, and agree on funding requirements. The remedial process requires
lead agency consultation with the "support" agency prior to publication of the
proposed plan and the inclusion of a statement in the notice of the proposed
plan detailing the support agency's position on the plan.
3.2.4 Training
The Agency increased its technical assistance and training efforts during
the year. A training course for Cooperative Agreement Project Officers at EPA
and at State agencies was developed. The Agency also developed a construction
management course for the EPA Regional offices and the States. The Agency will
continue to work with States and State officials' associations to provide
technical assistance to States on how to establish a program to implement CERCLA
and how to develop and enhance State capabilities to participate more fully in
CERCLA implementation.
32.5 Notice of Limitations on the Payment of Response Claims
Section lll(o) of CERCLA, as amended by SARA, provides that the President
shall develop and implement procedures to adequately notify concerned local and
State officials and other concerned persons of limitations on the payment of
claims for necessary response costs. The statute requires that the procedures
be developed no later than 90 days after enactment of the CERCLA amendments.
The notice procedures, once developed, would be utilized as soon as practicable
after a site is included on the NPL.
EPA was delegated the responsibility for implementing notice procedures
under CERCLA section lll(o) by January 17, 1987. Due to time constraints, and
the link with the procedures for filing claims against the Trust Fund under
section 112, EPA notified the public that section lll(o) and section 112
procedures would be proposed jointly.
On February 5, 1987, EPA published in the Federal Register a notice titled
"Limitations on Superfund Response Claims" (52 FR 3699) to advise the public of
the limitations on CERCLA response claims and that adequate opportunity for
comment would be provided before EPA adopted procedures for notice pursuant to
section lll(o) of CERCLA. EPA's Federal Register notice referred the public to the
NCP, at section 300.25(d), that requires that any person who takes a response
action and intends to seek reimbursement from the Fund must (1) notify EPA and
(2) obtain EPA's approval prior to undertaking the response action. EPA's
process of prior approval is known as "preauthorization."
65
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
EPA plans to propose procedures to notify persons of the limitations on
response claims (i.e., section lll(o) procedures) and the procedures for filing
claims against the Fund (i.e., section 112 procedures) in 1989. These
procedures, to be proposed as 40 CFR Part 307, will also serve to advise the
public of the requirements to be complied with in order to obtain
preauthorization.
32.6 Other Initiatives
A key stumbling block to increased State participation in CERCLA
implementation has been the lack of State capability. Thus, EPA is establishing
a core funding cooperative agreement. This non-site-specific funding vehicle
will support State functions necessary to implement CERCLA and build State
capability. Examples of eligible funding categories are general program
management, training, interagency coordination, general legal assistance, and
fiscal and contract management. Three CAs for core programs were funded in FY87.
In order to involve States in the initiation and development of guidance
on the remedial process, the Agency will continue the State Issues Workgroup,
which will provide a forum for State issues and concerns.
The Agency is now developing detailed guidance on how the State capacity
assurance will be made, when, and under what circumstances, it will be required,
and what States must do to provide EPA with an adequate assurance. The Agency
is also providing technical assistance and funding to States to generate the
data necessary to make this assurance (see section 2.3.12 of this Report).
Finally, the Agency is developing guidance for entering into CAs with
federally recognized Indian Tribes and working with the Bureau of Indian Affairs
and the Indian Health Service on how the operation and maintenance assurance can
be provided and how EPA will involve Indians in the response process. The Agency
develop implementing guidance that will address Indian involvement in hazardous
substances response, just as it now does for States. In addition, the revised
NCP includes Indian participation provisions.
66
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
4.0 PUBLIC INFORMATION AND COMMUNITY RELATIONS
4.1 Public Information
EPA has developed several resources that members of the public can use to
obtain information about the program in general, to get an answer to a question
about a particular Superfund site, or to get an update on regulatory development
activities. In addition, EPA has established an Ombudsman to resolve complaints
about Superfund actions.
4.1.1 Superfund Hotline
The Superfund Hotline (1-800-424-9346; 382-3000 in D.C.) is EPA's public
information service for Superfund-related questions. During calendar year 1987,
the Hotline received a total of 19,376 inquiries: 16,346 requests for
information and 3,030 document requests. The number of inquiries has increased
steadily each year.
The Hotline provides help with interpreting CERCLA, as amended by SARA, and
SARA provisions and related regulations, and answers a wide range of questions
on the Superfund program. If an inquiry cannot be answered by the Hotline, the
information specialist will refer the issue to the appropriate office (e.g.,
Office of General Counsel) and will report the information back to the caller.
Document requests are also handled by the Hotline; orders are taken for
publications or the caller is referred to the correct source.
In addition to responding to questions about EPA activities, the Hotline
can refer callers to the correct State or Regional coordinator. Questions about
Title III (Emergency Planning and Community Right-to-Know) were not handled by
this service during FY87.
4.12 Superfund Docket and Information Center
The Superfund Docket and Information Center (SDIC) is the public document
records center for rulemaking actions and regulatory decisions under CERCLA as
amended by SARA, and was established shortly after enactment of Superfund in
1980. Rulemakings and records of proceedings under the Emergency Planning and
Community Right-to-Know Act of 1986 (SARA Title III) are also included. Also
included are CERCLA guidance documents and directives, Records of Decision, and
information supporting rulemaking under section 3012 of the Resource Conservation
and Recovery Act (RCRA). The docket supports EPA staff and management, while
also serving the public right of access.
The rulemaking dockets contain background data, public comments on
regulatory actions, Federal Register notices, transcripts of public hearings, support
documents for regulatory decisions, correspondence/memoranda, and Administrative
Records. The docket also prepares responses to requests under the Freedom of
Information Act (FOIA). Rulemaking records which have had prior Office of
General Counsel (OGC) approval are available to the public for viewing. Copies
of operating directives and RODs and signed decision documents are also
available.
67
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
The public is allowed access to docket materials upon announcement of the
rulemaking in the Federal Register. No access is granted prior to the announcement
because (1) the Federal Register notice needs to be included in the docket index as
part of the Agency's rulemaking rationale, and without it the index would be
incomplete, and (2) visitors would have an unfair advantage over the general
public who rely on the Federal Register for notice of rulemaking. The SD1C responds
to all manner of inquiries; specific requests by the public to view files are
by appointment.
The SDIC is located in Room M-2427 in EPA Headquarters, at 401 M Street,
S.W., Washington, B.C. 20460. The main telephone number for the SDIC is (202)
382-3046 (docket appointments) and (202) 382-6940 (Superfund documents/ROD
information). SDIC hours of operation are Monday through Friday from 9:00 a.m.
to 4:00 p.m. The SDIC is closed on Federal holidays.
4.13 Public Information Center
The EPA's Public Information Center (PIC) distributes a wide variety of
general, non-technical information to the public (202/382-2080). EPA
publications on all major environmental topics, including Superfund, are
available through the PIC.
When the public expresses an interest in a topic on which there are no
publications, the center informs the appropriate EPA Program Office about the
public interest in the topic, so that the office can develop appropriate
publications or fact sheets. In addition to distributing informational
materials, the center refers requests to the appropriate source. The PIC
maintains a limited on-site inventory of publications, and will order other
publications from its Cincinnati warehouse.
4.1.4 Hazardous Waste Ombudsman
EPA has established an Office of Ombudsman at Headquarters (202/475-9361)
and in each Regional office. In FY87, the Ombudsman program handled over 2,000
questions and complaints. An ombudsman is an impartial public official who
investigates questions and complaints about government officials or
administrative actions and seeks to correct problems where warranted. The term
ombudsman originated in Sweden, where an ombudsman was first appointed in 1809.
EPA's Ombudsman program is intended to assist citizens and members of the
regulated community who have been unable to voice a complaint or get their
problems solved through normal channels. The program is not intended to
circumvent existing channels of management authority or established
administrative and formal avenues of appeal.
42 Community Relations
In addition to the general information activities described above, EPA
promotes two-way communication between the communities affected by specific
releases of hazardous substances and the lead government agencies responding to
those releases through its Superfund community relations program. The program
68
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
ensures that the local public is provided with accurate and timely information
about the progress of response plans. This information enables the local public
to comment on and help make decisions about response actions. A thorough,
well-planned community relations effort is an integral part of every Superfund
response.
Even before the CERCLA was enacted in 1980, EPA began development of a
community relations program that would be able to respond to the variety of
interests and information needs of diverse site communities across the country.
42.1 Public Participation Under CERCLA Section 117
Beginning with enactment of SARA, EPA implemented requirements necessary
to comply with CERCLA section 117 public participation provisions and expects
to complete implementation in FY88. The revised NCP will include additional
regulations on community relations that reflect CERCLA requirements and the
experience EPA has gained over the past seven years. Currently, EPA is
developing guidance on community relations for the settlement process, the
litigation process, and for Federal facility sites subject to CERCLA section
120. All guidance and training programs, including the handbook Community Relations
in Superfund, will be updated to comply with the new CERCLA requirements. An
interim version of this manual was completed in October 1987. New community
relations fact sheets are also being developed.
Section 117 of CERCLA, which was added by SARA, provides for public
involvement in the decisions made concerning cleanup actions at Superfund sites.
Section 117 requires that the public be informed of proposed remedial action
plans; be given an opportunity to comment on these proposals; be informed of
final plans, including EPA responses to public comments on the proposals; and
be informed of any actions taken that differ from the final plans, as well as
the reasons for the changes.
Naturally, the efforts made by EPA's community relations program are
assisting in the implementation of the section 117 requirements. Of particular
importance is EPA's long-standing effort to incorporate components of the
Superfund community relations program into Superfund technical activities. This
past year, community relations skills training was completed for more than 500
hazardous waste officials in 14 States as well as technical enforcement and
community relations personnel in the 10 EPA Regional offices. Community
relations training has been incorporated as a module in all of the major
technical training programs, from the CERCLA orientation training to the Record
of Decision Workshops for EPA staff.
As EPA Superfund policy and guidance documents are developed and updated,
discussions of community relations issues and activities are incorporated so
that EPA and State technical, enforcement, and community relations staff are
equally knowledgeable and encouraged to work as a team. The Agency continues
to provide support as well as initiate innovative community relations activities.
This year, EPA produced fact sheets for public distribution and completed a pilot
project on dispute resolution for three EPA Regions.
69
-------
Progress Toward Implementing Super-fund: Fiscal Year 1987
422 Technical Assistance Grants Under CERCLA Section 117(e)
In 1987, EPA requested comments from the public on its proposed regulations
implementing the technical assistance grants (TAG) program. The TAG program is
designed to provide funds to communities for the purpose of their hiring advisors
to interpret technical information related to cleanup of Superfund sites listed
on the NPL. This assistance will provide affected communities with a better
understanding of the nature of the site problems and alternative solutions, thus
allowing them to participate more effectively in the decisions made concerning
Superfund sites. The TAG program can provide grants of up to $50,000 per site.
Only one grant may be issued for each site, and the community is required to
contribute 35 percent of the amount required to obtain the necessary technical
assistance.
The comments received on the proposed TAG regulations were considered in
formulating interim TAG regulations, which were published on March 24, 1988 (53
FR 9736). The interim regulations enabled the Agency to begin accepting
applications and awarding grants, while it continues to receive additional
comments that will be considered in developing the final TAG regulations.
423 Public Participation in Development of Administrative Records Under CERCLA Section 113(k)
On May 29, 1987, EPA issued a directive to its Regional offices that details
initial implementation steps to meet the section 113(k) requirement for
administrative records for the selection of response actions at Superfund sites.
Under section 113(k), EPA must provide for the participation of interested
persons in the development of the administrative record for both removal and
remedial actions. The directive instructs the Regional offices to establish
administrative records (if not already established) at each Superfund site. In
addition, the directive details contractor support and assistance available to
the Regional offices and outlines documents that must be included in
administrative records. The directive was designed to assure that administrative
records would be established and in place in time for FY87 ROD signatures, and
to ensure consistency in the administrative records for different sites.

5.0 PROGRAM AND IMPLEMENTATION SUPPORT
EPA undertook a number of program and implementation support initiatives
to facilitate the implementation of .CERCLA, train workers in health and safety,
and expedite Superfund program progress. A major accomplishment was the creation
of a sophisticated management information system, which was achieved by
consolidating and improving previous administrative support systems. EPA also
assessed its training, technology transfer, and information dissemination needs
and began implementing a program-wide strategy that resulted in more than 200
presentations of 50 different courses to more than 11,000 attendees, as well as
the publication of a number of training documents. Finally, EPA diversified
its contracting program and delegated increased contract management
responsibility to the Regions in order to better meet the needs of the removal
and remedial programs and to expedite completion of response actions.
5.1 Administrative System Support
Access to the information contained in the following seven data bases is
essential for maintaining EPA's ongoing capacity to implement Superfund
activities.
5.1.1 Modification of CERCLIS
The first generation CERCLIS contained pre-remedial data on approximately
27,000 sites, including their identity and location, cost of cleanup, descriptive
data, and Region-specific data. During the year, EPA implemented a second
generation CERCLIS by incorporating into the existing system part of the
information and data contained in the following four systems:
• The Superfund Comprehensive Accomplishments Plan provides
data on all response activities.
• The Removal Tracking System provides a comprehensive removal
data base that includes start date, location, lead agency,
and NPL status.
• The Case Management System contains general information on
all enforcement activities, with information on cost
recovery and settlements.
• The Remedial/Removal Financial System Site File tracks the
actual obligations for operable units for each facility (or
site) and event (e.g., a RI/FS start) for site activities
conducted under lAGs, CAs, or contracts with States, Indian
Tribes, political subdivisions, or other Federal agencies.
This expanded CERCLIS is the national reporting, tracking, and management
tool of Superfund. The pilot test of the national data base was completed by
Region 9 in August 1987. CERCLIS, second generation, became operational at the
end of October 1987.
71
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
5.1.2 Superfund Comprehensive Accomplishments Plan
The Superfund Comprehensive Accomplishments Plan establishes annual
activity and financial targets for the accomplishment of response actions. Each
year, EPA Headquarters works closely with the Regional offices to determine
program targets. These targets are tracked against program accomplishments
throughout the year.
In FY87, EPA improved SCAP's usefulness as a planning and management tool.
First, EPA incorporated SCAP into second generation CERCLIS and, consequently,
the Regions became responsible for the planning and reporting that determine the
adequacy of budgetary allotments and how Regional accomplishments are reported.
Second, EPA began using SCAP to track enforcement activities as well as remedial
and removal activities. This integrated approach to SCAP development was
implemented in the following ways:
• Target setting and reporting for Fund-financed activities
and enforcement/PR? activities were combined;
• Uniform reporting formats combining removal, remedial, aind
enforcement information were developed;
• The enforcement case budget was integrated with the SCAP;
and
• Regions began planning the use of Technical Enforcement
Support contract and interagency agreement resources on a
site-specific basis, the basis on which remedial activities
are planned.
5.13 Strategic Planning and Management System/Action Tracking System
The objective of the Strategic Planning and Management System (SPMS) is to
develop a strong system of integrated planning, guidance, and oversight that
includes the States in EPA's planning and program implementation. The EPA
Administrator establishes long-term strategies and a priority list. SPMS
provides a framework and system for accomplishing the objectives laid out by the
Administrator.
The Action Tracking System (ATS) is one component of SPMS. It follows the
regulatory development of major regulations, guidance, and policies across the
Agency for all programs. The ATS provides the Deputy Administrator with reports
pinpointing potential problems as regulations and guidance are developed.
In September 1987, CERCLA and SARA were incorporated into ATS. OSWER will
be required to track supplemental guidance and regulations listed in the "Agency
Operating Guidance." OSWER must also track any CERCLA or SARA regulations
published bi-annually in the Federal Register' s "Unified Agenda."
72
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
5.1.4 Superfund Enforcement Tracking System
This data base, operated and maintained by the Office of Waste Programs
Enforcement (OWPE), contains the names and addresses of PRPs. In FY87, the data
base was expanded to include the NPL status of each site, the date a notice
letter was sent to all PRPs, and the contact person for each site.
5.1.5 Case Budget System
The Case Budget System tracks enforcement program work assignment activity
and funds for the Technical Enforcement Support contracts. This system was
expanded to include fund requests, actual fund allocations, and work assignment
numbers. As a result, contracts are now more easily and accurately tracked.
5.1.6 Cost Documentation Monitoring System
This data base contains the requirements to support cost documentation for
section 107 case referrals, and the data on documented costs. In FY87,
information on statutes of limitations for section 107 cases began to be
tracked.
5.1.7 OSWER Directives System
The OSWER Directives System provides a systematic process for identifying
and communicating policy and procedures to the Regions. This Directive System
establishes a document numbering system designed to track and manage all current
program policy and guidance related to implementation in the Regions and States.
Additionally, the System permits ease in identification of approval level of
directive documents, provides a central Regional location for all directives,
and maintains a comprehensive index of valid directives.
EPA considers only directives that originate in or are issued by one of the
OSWER offices, Regional offices, or other EPA offices, and that affect at least
one of the Regional Waste Divisions or Environmental Services Divisions
appropriate for inclusion in the system. Also, documents issued by the
Administrator or Deputy Administrator that are not included in the Agency
Directives System will be included in the OSWER Directives System. Each
directive is numbered to identify the originating office. Superfund Directives
are numbered from 9200 through 9399 and 9800 through 9899.
In FY87, EPA offices issued approximately 40 Superfund-related directives
and policies. The following major directives were issued:
• CERCLA Compliance with Applicable or Relevant and
Appropriate Requirements Guidance;
• Selection of Remedy Guidance;
• Hazard Ranking System Revisions;
• Technical Assistance Grants;
• Nonbinding Allocation of Responsibility Guidance; and
73
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
• De Minimis Settlement Guidance.
52 Training Programs
OSWER is responsible, under CERCLA section 311(b), for the coordination of
training in the areas of solid and hazardous waste and emergency response.
Activities related to these responsibilities include long-range planning,
analysis, and evaluation; the identification of training requirements; training
development, delivery, and coordination within and among program offices; and
management and training support to EPA Headquarters, Regions, arid States as
requested. The overall approach to training being implemented by OSWER is one
that will focus training on improving job performance, providing a consistent
format for training development and delivery, and maximizing the effectiveness
of training resources through the use of innovative training methods.
The recently established Office of Program Management and Technology (OPMT)
within the Office of Solid Waste and Emergency Response serves as a focal point
for coordinating research and development, technology transfer, and training.
In conjunction with the Office of Research and Development (ORD), this office
has specific responsibility for the development and implementation of long-term
training and technology transfer strategies for OSWER. Technological innovations
developed through research and demonstration programs (such as the SITE program
described in section 7.2 of this Report) are incorporated into technology
transfer activities and training to ensure that advances in knowledge and skills
are made available to Superfund staff.
52.1 Training Programs in Fiscal Year 1987
OSWER provided a large number of training courses, seminars, and workshops
related to critical training needs as well as in other areas such as health and
safety. Approximately 50 different courses were offered during the fiscal year.
In all, more than 200 sessions were attended by approximately 11,000 individuals.
This represents a substantial increase over the 6,000 to 8,000 persons trained
in FY86. EPA and State and local agency staff were equally represented,
accounting for approximately 80 percent of trainees, with the remaining 20
percent distributed among other Federal agencies, contractors, and industry.
Training courses were offered in EPA Headquarters, EPA Regions, and at
Environmental Response Branch Training Centers in Cincinnati, Ohio, and Edison,
New Jersey.
OSWER's FY87 extramural budget for Superfund training activities included
training funded by EPA Headquarters, continuing training in safety and Superfund
operations operated by OERR's Emergency Response Division, and additional funds
expended by the Regional offices. OSWER awarded more than $43,000,000 in
training contracts.
522 Meeting Critical OSWER Training Needs
OSWER completed a training needs assessment in March 1986 that identified
several areas in which it considers training a high-priority need: ground-water
monitoring, CERCLA regulations, risk, remedial engineering, cleanup technologies,
74
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
community relations, compliance monitoring, contingency planning, and on-scene
coordination. To meet these training needs, EPA developed the following tools:
• A draft Ground Water Curriculum and Implementation Plan that
identified ten critical training needs in this area.
Efforts are underway to develop the required training.
• A National SARA Videoconference that was viewed by over
5,000 persons in March 1987 and was followed by a series of
regional SARA Implementation Meetings in six major cities.
In addition, the CERCLA orientation course was revised to
reflect the new CERCLA provisions.
• A Risk Assessment course focusing on the Superfund Public
Health Evaluation Process that was delivered in all ten EPA
Regional offices during FY87.
• A training module entitled Hazardous Waste Cleanup Tech-
nologies and Their Application at Superfund Sites that was
piloted in early FY87 and covered the existing state-of-the-
art in hazardous waste engineering methods. A seminar on
innovative and emerging cleanup and engineering technologies
was also presented in concert with ORD's Hazardous Waste
Engineering Research Laboratory as a part of OSWER's
technology transfer series.
• A Superfund Community Relations Training Strategy that
included proposed courses for implementation in FY88.
• A focused task analysis for Superfund Enforcement Compliance
Monitoring that concentrated on the functional areas of
ground water and incineration.
• The National Response Team (NRT) Training Strategy, in
coordination with other NRT agencies, to address training
in the areas of contingency planning and hazardous materials
response. The strategy addresses several issues related to
interagency coordination, needs assessment, task analysis
and identification of training target audiences, and it
suggests implementation activities in each area.
• A draft On-Scene Coordinator/Remedial Program Manager
Training Curriculum to provide Superfund on-scene
coordinators (OSCs) and remedial program managers (RPMs)
with task-related training critical to fulfilling Agency
objectives. The curriculum delineates required, optional,
and specialized courses for Superfund employees.
523 OSWER Training Documents
In an effort to implement a comprehensive OSWER training and technology
transfer program and execute the responsibilities of the new Office of Program
75
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Management and Technology, OSWER has developed several training documents.
Among the most significant of these are the following:
• The Technology Transfer Strategy was developed in April 1987 to
assist OSWER in disseminating innovative and emerging
environmental research activities at the leading edge of
technology.
• The OSWER Training Implementation Plan presents a management plan
to address the major recommendations contained in the OSWER
Training Strategy.
• The OSWER Training Policies and Procedures document is intended to
be used by Headquarters and the Regions as a guide to the
conduct of training activities. The document addresses the
areas of curriculum planning and revision, needs definition,
training priorities, course development and deliv€;ry
activities, and training evaluation and program management.
Volumes I and II of the policy document were issued as OSWER
Directive No. 9018.00-2, September 30, 1987.
5.2.4 Organizational Improvements
OSWER has made significant progress in implementing organizational
improvements related to greater coordination and increased management commitment
to training and technology. A brief description of several major program
accomplishments follows.
Superfund Work Force Planning Project
Early in the fiscal year, OSWER created a task force made up of
representatives of the Office of Human Resource Management (OHRM), OSWER, and
several of the Regional offices to implement the recommendations contained in
the Superfund Work Force Planning Study. Efforts to implement the
recommendations of the study and the subsequent GAO Report to Congress on Superfund
Improvements Needed in Work Force Management, dated October 1987, are underway. A plan
is currently being developed and is scheduled for implementation in FY89.
Technology Transfer
The Technology Transfer Strategy, issued jointly by OSWER and ORD in April 1987,
outlines a systematic approach for disseminating information. The strategy
focuses on creating an organizational framework within which the Agency can
better define problems in the field, develop and disseminate technical products,
and evaluate the effects of those products. Proven techniques are then
transferred to Regional, State, local and private sector users through training
and other methods.
76
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
National Response Team Training Committee
The NRT Training Committee is responsible for coordinating training in
contingency planning and hazardous materials response among the member agencies
of the NRT. In FY87, the NRT Training Committee:
• Supported a Hazardous Materials training conference in an
effort to establish Federal, State, and local relationships;
• Developed a concept paper on how best to establish focal
points for coordinating State and local hazardous materials
training;
• Coordinated meetings and conducted briefings for national
trade organizations to increase private industry
participation in a coordinated hazardous materials training
system;
• Provided support for the development of a videoconference
on public health impacts of hazardous materials incidents;
and
• Conducted a focused task analysis for local response teams,
hazardous materials teams, and medical teams to ensure that
training is related to job requirements in this area.
Training for Other Federal Agencies
As part of its coordination with other Federal agencies in hazardous
substance response, OSWER provided specialized training in EPA's hazardous waste
programs and policy to both the National Park Service and the Indian Health
Service. As a part of the Department of the Interior training program for Park
Service Safety Officers, the Technology Staff of OPMT developed and delivered
specialized training that emphasized the handling of hazardous materials and the
responsibilities of Federal facilities under Superfund. For the Indian Health
Service of the Department of Health and Human Services, a course providing an
overview of the Superfund program and EPA's Indian Policy was developed. The
training also reviewed the legislative background of jurisdictional issues
involving hazardous waste releases on Indian land.
5.2.5 Future of Training Programs
OSWER has developed a structured and organized training program to meet
Superfund program needs, and has developed plans and policies to provide focused
and coordinated training, improved training capacity, and a stronger commitment
to training. Future training funds budgeted for Superfund will be used to
implement innovative training methods to increase the effective use of training
resources. OSWER will build upon the accomplishments outlined above to
implement the ideas that have been developed in both the training and technology
transfer areas. The Superfund program will develop the technology assistance
concept, and OSWER will work toward developing the means to expand opportunities
77
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
for the participation of small and minority business enterprises in training and
technology transfer.
53 Contracting Support and Programs
53.1 Overview
EPA used contracts in five categories to implement the Superfund program:
(1) Headquarters/Regional policy and program implementation; (2) removal action;
(3) remedial action; (4) enforcement support; and (5) contract laboratory
services. In FY87, the Superfund program administered 153 active contracts,
with a potential value of $2,363,355,000:
• Six contracts, with a potential value of $63,000,000,
support Headquarters and Regional programs for policy
development and implementation. Under these contracts,
contractors provide both technical and non-technical
assistance.
• One hundred thirteen contract laboratory contracts, with a
potential value of $288,000,000, supported the Contract
Laboratory Program (CLP) to provide laboratory services for
both removal and remedial actions. The greatest number of
Superfund contracts fall into this category.
• Seventeen contracts, with a potential value of $946,255,000,
supported the removal program. Removal program contracts
provide EPA with support in emergency response, other
removal actions, spill prevention, and analytical services.
• Nine remedial action contracts provide EPA with technical
assistance during RI/FS, remedial design, and construction
stages. These contracts have a potential value of
$925,600,000.
• Eight enforcement contracts assist EPA in cost recovery and
litigation support operations. Combined they have a
potential value of $140,500,000; seven of the eight were
awarded in FY87.
Of these 153 active contracts, a total of 136 were awarded during the year,
with a potential value of $1,503,855,000. Exhibit 5.3-1 lists FY87 contract
awards and their potential value.
Two significant contract initiatives are represented among the contracts
awarded in FY87: the Alternative Remedial Contract Strategy (ARCS) and the
Environmental Services Assistance Teams (ESAT) contracts. ARCS contracts
perform the same functions as, and will replace, remedial planning (REM)
contracts. They are, however, awarded on a Regional basis rather than on an
east-west zone basis. The ESAT contracts will provide laboratory services, as
requested, to all areas of the Superfund program.

53.2 Response Support Contracts
Laboratory Support Contracts
During the fiscal year, EPA awarded 110 new contracts to provide sample
analysis services under the Contract Laboratory Program. These contracts have
a potential value of $221,000,000. The CLP provides laboratory service for all
removal, pre-remedial, and remedial actions, and is responsible for analyzing
samples taken at various stages of the cleanup process. EPA awards contracts
for organic, inorganic, and dioxin analytical services. These contracts are
awarded continually, depending on capacity needs.
In FY87, the CLP ran a total of 91,524 Superfund site samples. Most CLP
analysis is done for site samples taken during RI/FSs. Exhibit 5.3-2 shows the
annual number of RI/FS site samples analyzed by the CLP since the inception of
the Superfund program.
Organic and inorganic samples, because of different contractual
requirements, have different result turnaround times. The median processing
time for an organic sample is 32 days and for an inorganic sample it is 31 days.
Sample results are returned to the Region for review, the length of which varies
from several days to several months. With few exceptions, turnaround times on
average have been maintained below the contract-allowed 40 days. Data

EPA's latest awards in support of the laboratory program are two ESAT
contracts worth $35,000,000 each. These two contracts, both awarded at the end
of FY87, provide assistance to EPA's Regional offices in laboratory, analytical,
and review services. The contracts cover different geographical zones (the
eastern zone includes Regions 1, 2, 3, 4, and the western zone includes Regions
5, 6, 7, 8, 9, 10, and HQ). Their periods of performance can extend to 4 years
depending on the number of options exercised.
Removal Support Contracts
The removal program traditionally has been supported by Emergency Response
Cleanup Services (ERGS) contracts. The ERCS contracts were recompeted this year
and awards range in potential value from $60,000,000 to $165,000,000 over a 4-
year period of performance. ERCS contractors operate on a zone basis, with
several EPA Regions included within each of four zones:
Zone I: Regions 1, 2, and 3;
Zone II: Region 4;
Zone III: Region 5; and
Zone IV: Regions 6, 7, 8, 9, and 10.
80
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Also, EPA developed and began implementation of a strategy for awarding smaller
removal contracts, "mini-ERCS, " on a Regional basis. EPA also plans to provide
additional support to the Regions in FY88 by dividing one of the ERGS zones into
two smaller zones and awarding a contract for each of them.
Four contracts were awarded to support the dioxin removals being conducted
at Castlewood and other related sites in the St. Louis, Missouri area. These
contracts have a total potential value of approximately $75,452,000, over a 4-
year period. EPA also awarded a contract with a potential value of $703,000 to
conduct a site-specific removal at the American Steel Drum site in Bedford, Ohio
in EPA Region 5.
EPA awarded two Technical Assistance Team (TAT) contracts in December 1986
to replace the previous sole TAT contract. The combined potential value of both
contracts over a 5-year period of performance is $219,0000,000. Each contract
covers a different portion of the country. The eastern zone contract supports
Regions 1-5, the Emergency Response Team, and EPA Headquarters. The western
zone contract supports Regions 6-10. The TAT contracts serve as adjuncts to the
ERGS contracts and provide for initial site response support, determinations of
the size and nature of the site, and support for On-Scene Coordinators during
actual cleanup.
This year, the Environmental Emergency Response Unit (EERU) contract was
divided into three separate contracts, a Response Engineers and Analytical
contract, an Environmental Response Training contract, and an EERU contract.
These contracts provide emergency response support to hazardous waste sites or
spills posing an immediate threat. These first two contracts were awarded in
FY87. The Training and Response Engineers contracts will run for 5 years and
provide up to $138,000,000 in support, primarily to provide engineering response
for the Environmental Response Team's field activities.
One ERGS contract was awarded to an 8(a) (minority) firm. This contractor
will also be allowed to perform small remedial operations. The contract has a
potential value of $12,253,000 and extends from October 1987 through September
1988. Two Regional ERGS were awarded, both of which are also 8(a) contracts.
Remedial Support Contracts
EPA developed and commenced implementation of the ARCS, a substantial
change in its remedial contracting program. The ARCS concept is aimed at
maximizing competition in the remedial program, providing additional incentive
for improved performance, and promoting project continuity. There will be
numerous smaller remedial response contracts awarded continuously in each Region
or, in some cases, in several Regions combined. Each Region will award six to
ten contracts.
Work will be assigned to these contracts based on quality of performance
and the program will emphasize keeping the same contractor involved in all
phases of the cleanup process. The first awards were made in EPA Regions 3 and
5 in January 1988; coverage in all Regions is planned by the end of FY89.
Contracts will range from $60,000,000 to $250,000,000 in potential value over
81
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
10-year periods. As in the current remedial contracts, the ARCS will contain
large subcontracting pools to maximize the number of contractors participating.
Two Field Investigation Team (FIT) contracts were awarded in FY87 to
provide support for pre-remedial activities; each has a 5-year period of
performance and will expire in November 1991. One of these contracts has a
potential value of $130,000,000 and provides support for Regions 1-4 in the
eastern half of the country. The other contract has a potential value of
$150,000,000 and supports Regions 5-10 in the western half of the country.
Minority business firms were awarded two smaller contracts to perform
remedial response activities. They have a potential value of $21,500,000 each,
and have 4-year periods of performance. EPA also awarded a single contract with
a potential value of $2,600,000 designed specifically to procure support for
remedial response activities at the Wausau, Wisconsin site through 1991.
Enforcement Support Contracts
EPA awarded one contract, with a potential value of $10,500,000, to provide
litigation services for cost recovery, support PRP searches, and fund oversight
for PRP and Federal facility cleanups under both CERCLA and RCRA.
5.4 Superfund Resource Utilization
This section presents data and information on the utilization of resources
from the Hazardous Substance Trust Fund (Superfund) for implementation
activities by EPA and other Executive branch departments and agencies in FY
1987. The data and information included in this section were obtained primarily
from EPA Superfund budget documents. Superfund resource requirements of EPA and
other Executive branch departments and agencies for FY 1988-1991 and beyond FY
1991 are discussed in Chapter 13.
EPA uses Superfund resources in four major areas:
• Hazardous Substance Response;
• Enforcement;
• Management and Support; and
• Research and Development.
Both EPA Headquarters and the Regional offices perform these Superfund
activities. Fiscal year and historical transfers to Regional offices are shown
in Exhibits 5.4-1 and 5.4-2. In addition, EPA transfers resources to other
Federal departments and agencies to assist them in meeting their
responsibilities under CERCLA. The Agency also transfers funds from the
Superfund appropriation to State governments and other private sector
organizations (e.g., the National Governors' Association) to assist EPA in the
implementation of CERCLA.
In FY 1987, the Agency utilized a total of $1,050,748,900 from the
Hazardous Substance Superfund appropriation for CERCLA implementation, including
SARA Title III activities. Superfund implementation activities that EPA
conducted under the four major program areas accounted for $984,600,900. The

Agency utilized a total of $66,148,000 for Superfund general interagency support
to other Federal departments and agencies, including Superfund Interagency
Budget transfers and site-specific interagency agreements.
5.4.1 EPA Superfund Program Activities
EPA utilized a total of $984,600,900 (94 percent of the total amount
obligated from the Trust Fund) to conduct Superfund implementation activities
under the Hazardous Substance Response, Enforcement, Management and Support, and
Research and Development programs. These activities were supported by a total
of 2,174.3 workyears at both EPA Headquarters and in the Regional offices.
Exhibits 5.4-3, 5.4-4, and 5.4-5 illustrate current and historical resource
utilization.
Hazardous Substance Response
The two Hazardous Substance Response programs, Spill and Site Response and
Hazardous Substance Response Support, are utilized to protect public health and
the environment from dangers associated with releases of hazardous substances
into the environment. These programs provide the necessary funding and support
to undertake short-term emergency responses and long-term site cleanups.
Activities include responding to spills and emergency releases of hazardous
substances, conducting remedial work at abandoned hazardous waste sites, and
providing training and technical support to Agency, State, and local government
personnel.
The majority of the work performed under the Spill and Site Response
program was geared toward implementing CERCLA provisions and regaining the
momentum of the Superfund program. The regulatory and guidance framework for
the removal program was completed, including the use of revised removal
authorities and the promulgation of final regulations on CERCLA notification,
reportable quantities, and the designation of additional hazardous substances.
The Agency focused its remedial efforts on initiating Rl/FSs at NPL sites and
beginning design and implementation at sites where planning was completed.
Enforcement
The primary goal of Superfund enforcement activities is to achieve the
maximum possible response from potentially responsible parties. Superfund
enforcement activities are conducted through four programs: Technical Support -
Office of Enforcement and Compliance Monitoring (OECM); Technical Enforcement;
Legal Enforcement; and Criminal Investigations.
The OECM program supports the Superfund activities of the National
Enforcement Investigations Center (NEIC), including special environmental
monitoring work, evidence audit control processes to ensure proper chain-of-
custody procedures, cleanup of Federal facility sites, and nonbinding
preliminary allocations of responsibility. The Technical Enforcement Program
develops the technical documentation for Superfund enforcement and initiates
enforcement actions. The Legal Enforcement program provides the legal staff for
CERCLA enforcement. EPA Headquarters support for judicial enforcement under
this program increased in 1987 as EPA set precedents with new types of

enforcement activities, such as de minimis settlements, consent decrees with
responsible parties to undertake response actions, and civil remedies for
reportable quantity violations. The basic purpose of Criminal Investigation,
under the direction of NEIC, is to initiate and conduct criminal investigations
under CERCLA.
Management and Support
Superfund management and support activities provide the financial,
administrative, and support services necessary to manage and implement the
Superfund program. These activities include: financial management to track and
report on the use of the Hazardous Substance Superfund; administrative
management of contracts personnel, information systems, office and laboratory
services, and safety training; services for space, utilities, and other non-
personnel support needs, including computer services.
Management and support also includes legal services; auditing services;
policy analysis and program evaluation; budget development and oversight;
effective communication with interested parties outside the Agency; and
laboratory support for Superfund research. The Agency performs its Superfund
management and support activities under the following nine program areas:
(1) Financial Management; (2) Administrative Management; (3) Support Services;
(4) Computer Services; (5) Legal Services; (6) Office of the Inspector General;
(7) Office of Policy, Planning, and Evaluation; (8) Office of the Comptroller;
and (9) Office of Research and Development.
Research and Development
Superfund research and development activities support the Agency, States,
and industry in resolving technical problems that inhibit the effective
implementation of removal and remedial actions. Much research focuses on
adapting existing technologies and scientific information for the purpose of
controlling hazardous waste.
Superfund research and development (R&D) activities provide quality
assurance protocols and methods for sampling and analyzing hazardous waste
materials. Superfund R&D also develops techniques for field response personnel
to use in evaluating potential sites, and engineering and other technical
guidance for Federal, State, and local officials to use in conducting site
cleanup operations. Superfund research also includes evaluation of personal
protective devices and engineering controls to protect hazardous waste workers
and improve their efficiency. Superfund research and development activities are
conducted through the following seven programs: (1) Scientific Assessment; (2)
Monitoring and Quality Assurance; (3) Health Effects; (4) Environmental
Engineering and Technology; (5) Environmental Processes and Effects; (6)
Exploratory Research; and (7) Technical Information and Liaison.
5.42 Other Executive Branch Department and Agency Superfund Activities
Two sources of funding meet the resource needs of other Executive branch
departments and agencies for CERCLA implementation: (1) monies obligated to
these departments and agencies by EPA from the Hazardous Substance Superfund
89
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
appropriation, and (2) funds independently budgeted by other Federal departments
and agencies.
In FY87, EPA transferred a total of $66,148,000 from the Hazardous
Substance Superfund appropriation to other Federal departments and agencies.
EPA transfers Trust Fund monies to other Federal departments and agencies
through an interagency budget process under Executive Order 12580 that utilizes
general and site-specific interagency agreements (lAGs). General lAGs, funded
through either transfer allocation or reimbursable accounts, provided
$51,343,100 for ongoing activities that generally are not incident-specific,
such as developing program policies and guidance, training response personnel,
and conducting health research. Site-specific lAGs provided $14,804,900 for
those activities that are episodic in nature and taken in direct support of
specific site or spill response actions. Site-specific activities are generally
paid for on a reimbursable basis. Exhibit 5.4-6 presents data on the FY87
Superfund interagency agreements by department and agency.
The second source of funding used to meet other Federal department and
agency Superfund resource needs is monies that are independently budgeted by
individual departments or agencies for Superfund activities and support as part
of the President's annual budget submission. This source of funding for
Superfund activities is discussed in Chapter 13.
Department of the Interior
The NCP also designates the Department of the Interior (DOI) as Federal
Trustee for certain natural resources either lost or damaged due to hazardous
substance releases. DOI provides scientific and technical support in resource
damage assessments through its participation on the National and Regional
Response Teams.
Department of Transportation
The United States Coast Guard (USCG) is a part of the Department of
Transportation (DOT), except when operating under the Department of the Navy in
time of war. The USCG is the predesignated On-Scene Coordinator in the Coastal
Zone and has the authority under CERCLA to respond to any release or threatened
release of hazardous substances involving the shore, Coastal Zone, Great Lakes
waters, ports, and harbors. The USCG and EPA share responsibility for the
emergency response activities under the NCP. The USCG provides training to
maintain this response capability, conducts enforcement activities as necessary
in its areas of responsibility, maintains the National Response Center (NRG),
and supports the National Response Team and each of the Regional Response Teams.
In addition, the USCG (under section 108(a) of CERCLA) enforces the requirements
that commercial vessels using U.S. waters must provide evidence of financial
responsibility to pay for cleanup in the event of spills.
The Coast Guard utilized 1987 transfer funds to purchase safety equipment,
conduct response training for USCG personnel, upgrade the capabilities of the
NRC, and provide field data systems to support response programs and minimize
the possibility of harm to personnel from exposure to hazardous substances.

Department of Health and Human Services
Within the Department of Health and Human Services (HHS), the Agency for
Toxic Substances and Disease Registry (ATSDR) and the National Institute for
Environmental Health Sciences (NIEHS) have certain Superfund responsibilities.
ATSDR can investigate complaints of illness or disease related to exposure to
hazardous substances, conduct health studies and surveys, develop testing for
exposed individuals, and develop and maintain information on the health effects
of toxic substances. Under CERCLA, ATSDR must perform health assessments by
December 10, 1988 at all sites that were listed on the NPL as of October 17,
1986. HHS develops policies and procedures to ensure a coordinated Federal
approach in conducting the above activities. NIEHS administers a training grant
program in worker protection and a program for basic research, development, and
training to promote better understanding of the effect on human health of
exposure to hazardous substances.
With the funds EPA transferred to it, HHS collected the information and
developed the procedures necessary to provide continuing health-related support
to the Superfund program. Included in these efforts were development of health-
related field guidance in support of EPA emergency response actions; development
of standard guidelines for health and epidemiological studies at NPL sites;
production of worker health and safety technical guidance and field manuals for
individuals involved in response actions; and toxicological testing of chemicals
found at NPL sites.
91
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Department of Commerce
The National Contingency Plan designates the National Oceanographic and
Atmospheric Administration (NOAA) to act on behalf of the Secretary of Commerce
as Federal Trustee for natural resources in coastal and marine areas that are
lost or damaged due to hazardous substance releases. NOAA also provides
scientific and technical support for responses to such releases in coastal and
marine waters. Transfer funds received by NOAA provided training for the
scientific response team, the purchase and maintenance of protective equipment
for personnel, the development and maintenance of field instrumentation, and
the development of computerized contingency plans.
Department of Justice
The Department of Justice (DOJ) is responsible for the conduct and control
of all litigation under CERCLA. EPA is responsible for preparing the required
technical and legal documentation and cooperates with DOJ in negotiating consent
decrees for privately financed response actions. With the transfer funds it
received from EPA, DOJ provided civil and criminal enforcement litigation,
including counseling on and enforcement of administrative orders and warrants
for entry, and institution of suits to compel removal and remedial actions and
to recover Superfund response costs.
Department of Labor
The Occupational Safety and Health Administration (OSHA) of the Department
of Labor is responsible for worker protection at Superfund sites. The OSHA
Health Response Team assists EPA and other on-site personnel in protecting
workers at Superfund sites and in developing guidelines to improve current
methods of worker protection. OSHA utilized transfer funds to provide technical
assistance to EPA, initiate a special program for worker safety at Superfund
sites, support National and Regional Response Teams, and develop a required
worker protection standard.
Federal Emergency Management Agency
The Federal Emergency Management Agency's (FEMA) hazardous materials
(HAZMAT) program involves working with Federal, State, and local governments and
the private sector to provide guidance, deliver technical assistance, facilitate
information sharing, and promote interagency/intergovernmental coordination in
the areas of emergency preparedness, response, and mitigation. The overall goal
of FEMA's HAZMAT program is to reduce the frequency and severity of hazardous
material emergencies by enhancing the prevention and response capabilities of
Federal, State, and local agencies, and of the private sector. Much of FEMA's
HAZMAT program is accomplished through the National Response Team and the
Regional Response Teams. In the event of an emergency, FEMA assists in the
temporary or permanent relocation of individuals whose health is threatened by
the release of hazardous materials.

6.0 EPA RULEMAKING ACTIONS TO IMPLEMENT CERCLA
SARA created many new regulatory authorities under CERCLA. In response to
these new authorities, and as part of ongoing rulemaking activities, EPA and
other Federal agencies involved in the Superfund program initiated a significant
number of rulemakings during FY87.
Rulemaking activities that address specific Report chapter topics are
discussed in the appropriate chapter sections: reportable quantities (2.1);
the remedial program (2.3); and State involvement (3.2). Additional rulemaking
activities were undertaken for the following other regulatory authorities.
6.1 Designation of Hazardous Substances Under CERCLA Section 102 (a)
In the preambles to rulemakings published on March 16, 1987 (52 PR 8140,
8142) and April 22, 1987 (52 FR 13378, 13392), the Agency indicated that it
intends to designate as hazardous substances under section 102(a), 232
substances originally listed as Extremely Hazardous Substances (EHSs) under
section 302 of SARA. Section 102(a) of CERCLA authorizes the Administrator of
EPA to promulgate regulations designating as a hazardous substance any substance
that, when released into the environment, may present substantial danger to
public health or welfare or the environment. The notification and liability
provisions of CERCLA apply only to substances designated as hazardous substances
under the statute. Although EPA may take actions to respond to releases of
pollutants or contaminants that are not CERCLA hazardous substances , the Agency
cannot recover the costs of such response actions pursuant to section 107, as
it can in the case of response actions involving CERCLA hazardous substances.
The proposed rule to designate the non-CERCLA EHSs was published in the Federal
Register on January 23, 1989 (54 FR 3388). Currently, there are 725 CERCLA
hazardous substances.
Past and Ongoing Activities
On May 25, 1983, EPA issued an Advance Notice of Proposed Rulemaking (48
FR 23602) soliciting comments on approaches for determining which substances
should be proposed for designation as hazardous substances under CERCLA section
102(a). EPA continues to examine designation approaches and candidate lists of
substances; once a methodology has been prepared for identifying a candidate
list and for selecting substances from these lists, EPA will propose additional
substances for designation in future rulemakings.
62 Payment of Research Costs Under CERCLA Section 104(i)(5)(D)
EPA took no action to implement CERCLA section 104(i)(5)(D). Under this
section potentially responsible parties are liable for the costs of research
under section 104(i). The existing regulations under the Toxic Substances
Control Act (TSCA) and the Federal Insecticide, Fungicide and Rodenticide Act
(FIFRA) allow EPA to pass the major portion of research costs on to the
potentially responsible parties. In many cases, the costs of research conducted
under these programs are already borne by the manufacturers, processors, and
registrants of the substances. EPA, therefore, has determined that further
regulations are unnecessary.
93

Progress Toward Implementing Superfund: Fiscal Year 1987
63 National Contingency Plan Under CERCLA Section 105
Early in the fiscal year, EPA began a broad and comprehensive rulemaking
process to revise and restructure the NCP. The NCP is the primary regulation
directing government and potentially responsible party response to and cleanup
of discharges of oil and releases of hazardous substances, pollutants, and
contaminants. CERCLA section 105 mandates that the NCP be revised within 18
months of the date of enactment of SARA to incorporate statutory revisions
relating to selection of remedy. To carry out the rulemaking EPA formed a
workgroup that included staff from EPA Headquarters and Regional offices, as
well as representatives of the States and other Federal Agencies. The Agency
formed sub-workgroups for selection of remedy and State-involvement issues. The
NCP workgroup met 16 times during FY87, and numerous sub-workgroup meetings were
held. EPA management was briefed and consulted on a regular basis. EPA held
its closure meeting covering many parts of the NCP revisions in September 1987.
Closure on remaining items occurred in the first quarter of fiscal 1988, at
which time EPA consulted the NRT as required by Executive Order 12580. The
proposed NCP was published in the Federal Register in December 1988 (53 FR
51394).
The primary purposes of the rulemaking is to incorporate changes mandated
by CERCLA, as amended, and to set forth EPA's approach for implementing CERCLA.
In addition, the revisions:
• Reorganize the NCP to coincide more accurately with the
sequence of response actions taken pursuant to the NCP;
• Clarify existing language on roles, responsibilities, and
activities of affected parties; and
• Incorporate changes indicated by program experience since
the last revisions to the NCP in 1982.
When the revised NCP is promulgated all existing subparts will be revised (with
some consolidation), and several new subparts will be added.
The major substantive revisions to the NCP are included in a revised
subpart detailing the response process and new subparts on State involvement and
the administrative record. Among the significant issues being addressed in the
NCP revision are:
• Selection of remedy steps and criteria;
• State involvement in response activities;
• The purpose of the NPL;
• Compliance with ARARs; and
• Development of the administrative record.
94
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Revision of the HRS, an appendix to the NCP, also was undertaken during
FY87. Discussion of activities surrounding that revision is included in section
2.3.5 of this Report.
6.4 Financial Responsibility Under CERCLA Section 108
During the fiscal year, the Office of Solid Waste requested $100,000 from
the Superfund to pursue implementation of CERCLA section 108. SARA supplemented
the existing provisions in CERCLA section 108 on the proof of financial
responsibility to be required from owners and operators of vessels and from
other PRPs and on the handling of claims against their guarantors and insurers.
SARA supplements CERCLA section 108(b)(2) to describe ways in which the
financial responsibility of those involved with the production, transportation,
treatment, storage, or disposal of hazardous substances can be evidenced. The
President is authorized to promulgate regulations to implement these
requirements.
6.5 Awards Regulations Under CERCLA Section 109(d)
The Agency published interim final regulations implementing CERCLA section
109 (d) in the Federal Register in May 1988. SARA amended section 109 (d) to allow for
the payment of an award of up to $10,000 to any individual who provides
information that leads to an arrest and conviction of a person for a criminal
violation under CERCLA. Section 109(d) authorizes the President to promulgate
regulations prescribing criteria for these awards.
6.6 Review of Denied Claims Under CERCLA Section 112(b)(2)
Prior to the enactment of SARA, section 112(b)(4) of CERCLA required
creation of a Board of Arbitrators to review EPA's claim determination if a
claim was denied or a claimant disputed the amount of an award. Section 112(b)
of SARA revoked the statutory authority for an arbitration board and, in its
place, amended CERCLA 112(b)(2) to allow a claimant to request an administrative
hearing if all or part of a claim is denied. Consequently, EPA on September 8,
1987 (52 FR 33812), withdrew its rule at 40 CFR 305 for arbitration and is
currently drafting a rule for administrative hearings of denied claims.
6.7 Indemnification of Response Action Contractors Under CERCLA Section 119(c)
On October 6, 1987, EPA issued interim guidance on indemnification of
Superfund response action contractors (RACs) under section 119 of CERCLA (OSWER
Directive //9835.S). The interim guidance contains general section 119
indemnification guidelines and procedures for EPA Headquarters and Regional
contracting personnel and indemnification contract language. EPA is currently
working on final indemnity guidance and plans to publish (for public comment)
a proposed guidance in the Federal Register in 1988. After reviewing the public
comments, EPA plans to issue a final guidance document and to promulgate
regulations concerning RAG indemnification, as required by section 119.
All RACs have had their contracts modified to reflect the requirements of
section 119. In addition, several contractors working for States at Superfund
sites have entered into indemnity agreements with EPA, pursuant to section 119.
95

6.8 Reimbursement to Local Governments Under CERCLA Section 123(d)
On October 21, 1987 an interim final rule under CERCIA section 123(d) was
published in the Federal Register authorizing reimbursement to local governments.
The costs incurred in providing temporary emergency measures in response to
releases of hazardous substances can be reimbursed for up to $25,000 per
incident. The rule was published just four days beyond the statutory deadline
of October 17.
6.9 Natural Resource Damage Assessment Reimbursement Under CERCLA Section 301(c)(l)
CERCLA section 301(c)(l) authorizes the President to promulgate regulations
prescribing procedures for the reimbursement of costs incurred by Federal and
State officials and Indian tribes in assessing damages resulting from the
injury, destruction, or loss of natural resources. The Department of the
Interior published general, standardized procedures under section 301(c)(2)(A)
on March 20, 1987 (52 FR 9042). Administrative and site-specific procedures
under section 301(c)(2)(B) were published on August 1, 1986 (51 FR 27674). The
proposed rule to provide amendments to the final natural resource damage
assessment regulations, mandated by SARA and required to be promulgated no later
than April 17, 1987, was published on that date (52 FR 12886) by the Interior
Department. The final rule was published on February 22, 1988 (53 FR 5166).
SARA section 517(a), however, amended the Internal Revenue Code to prohibit
expenditures for the purpose of carrying out those provisions of CERCLA section
111 that authorized claims submitted by Federal, State, or Indian Tribe trustees
for reimbursement of the costs of assessing damage to a natural resource, or for
the restoration of a natural resource that had been injured, destroyed, or lost.
Consequently, on September 8, 1987, EPA withdrew the rule (40 CFR 306) and the
regulatory procedures (40 CFR 305) it had promulgated for evaluation and
submission of natural resource claims (52 FR 33812).
6.10 Health and Safety/Worker Protection Standards Under SARA Section 126(a), (e), and (f)
As required by SARA section 126(e), the Secretary of Labor promulgated in
the Federal Register on December 19, 1986 (51 FR 45654), interim final
regulations on standards for the health and safety protection of employees
engaged in hazardous waste cleanup operations. By October 17, 1987, the
Secretary was to have promulgated final regulations under section 126(a), with
an effective date one year later. The Notice of Proposed Rulemaking appeared
in the Federal Register on August 10, 1987 (52 FR 29620); the final rule was
promulgated on March 16, 1989.
Under SARA section 126(f), and within 90 days of the final regulations
promulgated by the Secretary of Labor, the Administrator of EPA must promulgate
identical standards for State and local government employees not covered by
State plans approved under section 18 of the Occupational Safety and Health Act
of 1970.

7.0 DEVELOPMENT AND EVALUATION OF PERMANENT TREATMENT TECHNOLOGIES
7.1 Overview
Section 301(h)(l)(D) of CERCLA requires the Administrator of EPA to submit
as part of his Annual Report to Congress an evaluation of newly developed
feasible and achievable permanent treatment technologies. The technologies
potentially subject to such an evaluation could range from those able to treat
source materials to those designed to deal with contaminated ground water.
Although EPA does not have a comprehensive program that systematically monitors
the commercial and research environment to identify and evaluate such
technologies, several important activities are underway.
In Superfund1s 7-year history, it has become apparent that a premium must
be placed on the use of permanent treatment technologies in conducting response
actions. The most common response method in use today is land disposal; yet,
it is neither completely reliable nor permanent. Continued use of inherently
temporary and potentially unreliable methods such as land disposal can be
expensive and inefficient over the long run because of the recurring need to
monitor and replace defective waste disposal containers. While some alternative
treatment methods are coming into use, overall, the development of new treatment
technologies has proceeded very slowly. SARA included provisions to encourage
EPA to conduct more research and development of hazardous waste treatment
technologies.
During fiscal year 1987, EPA took several steps toward establishing a
steady stream of new treatment technologies in the development pipeline. Most
importantly, the first demonstration of new treatment technologies under the
SITE Program was completed, and five more demonstrations are currently planned.
Also, other EPA activities not specifically directed towards technology
development are, nonetheless, generating new technology uses. These include:
• Treatability studies, undertaken as part of the
feasibility study, to determine the effectiveness of
different remedies;
• The Superfund Technology Support Project (STSP), a
technical assistance program to encourage the use of
new technologies; and
• A survey of treatment technologies used worldwide.
7.2 Superfund Innovative Technology Evaluation Program Design
Section 209(b) of SARA amends Title III of CERCLA by adding Section 311,
which directs the Agency to establish an "Alternative and Innovative Technology
Research and Demonstration Program." This Congressional mandate codified EPA's
existing Superfund Innovative Technology Evaluation (SITE) program, which had
been created the year before. The SITE Program is intended to: (1) accelerate
the development, demonstration, and use of new or innovative treatment
technologies; and (2) demonstrate and evaluate new, innovative measurement and
97
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
monitoring technologies. Section 311(e) of CERCLA requires an annual progress
report (at the time of the annual budget submission) on the demonstration
program the Agency is conducting. EPA submitted its first SITE report to
Congress in February 1988.
There are five components to the SITE program. Three of the components
concern the development of new treatment technologies:
• The Demonstration Program,
• The Emerging Technologies Program, and
• The Innovative Development and Evaluation Program.
Of these three programs, only the demonstration program was operating in
FY 1987. The Emerging Technologies Program and the Innovative Development and
Evaluation Program were expected to begin operation in FY 1988 and are not
discussed in this Report.
Section 7.2.2 of this report discusses the other two SITE program
components:
• The Measurement and Monitoring Techniques Development
Program, and
• The Technology Transfer/Clearinghouse Program.
72.1 Superfund Innovative Technology Evaluation Demonstration Program
The demonstration program is charged with finding new technologies that can
meet the new cleanup standards under CERCLA requiring greater reliance on
permanent remedies. The program's main focus is to provide sound engineering
and cost data on selected new technologies to aid in Superfund decisionmaking.
EPA uses two methods of identifying SITE participants:
• CERCLA section 311(b)(5)(B) solicitations, and
• Evaluation of technologies used by EPA's Regional
offices.
CERCLA section 311(b)(5)(B) requires the Administrator to publish
solicitations for innovative and alternative technologies suitable for full-
scale demonstration at Superfund sites. Two solicitations have been issued; the
first on March 15, 1986 and a second on January 15, 1987. The technologies
chosen must be at pilot or full scale, be innovative, and offer some advantage
over existing technology. Mobile technologies are of particular interest.
After consultation with EPA Regional staff and the developer, the Agency chooses
for these demonstrations sites where the wastes would best illustrate the
capabilities of the new technology.
A second method EPA used to identify SITE participants was an evaluation
of technologies used by EPA's Regional offices during removal and remedial
response actions.
98
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Demonstration Program Reports
Each demonstration program project results in two final reports:
• A technical report that documents the performance data
resulting from the demonstration and summarizes its
findings in terms of effectiveness, reliability, and
cost; and
• A report that evaluates the degree to which each
technology applies to other sites and wastes, the
limitations of the process, and its economics. The
report should provide the decisionmaker with enough
information to make a preliminary decision as to
whether this process can be used to treat a specific
problem.
In general, both reports should be available 6 to 8 months after the
demonstration is completed. These reports are distributed to Federal and State
hazardous waste cleanup offices and are also available through the Center for
Environmental Research Information (CERI) in the Office of Research and
Development, and the hazardous waste collection in the EPA library.
The Fiscal 1987 Demonstration Program
EPA worked with 11 technologies that were selected during FY86; one
demonstration was completed during the year. An additional demonstration was
completed just after the close of the fiscal year, and four more were completed
during the winter of 1987/88. Another five technologies have not yet been
scheduled for demonstration, either because a site could not be found to match
the technology, the technology is not at full scale development, or permitting
requirements have slowed the process.
Although a twelfth developer, Waste-Tech Services, Inc., was selected under
the first solicitation to demonstrate its fluidized bed combustion technology,
Waste-Tech notified EPA in July 1987 of its withdrawal due to indemnification
Issues.
Completed Demonstrations
Two SITE demonstrations have been completed. The first demonstration was
conducted from July 31 to August 6, 1987, at the Peak Oil Superfund site in
Tampa, Florida (EPA Region 4), by Haztech, Inc., of Atlanta, Georgia. This
demonstration used a transportable, 100-ton per day, thermal destruction system
technology developed by Shirco Infrared Systems, Inc. The Shirco process uses
rows of electrically powered silicon carbide rods to bring the waste to
combustion temperatures and then destroys any remaining combustibles in an
afterburner. The full-scale system can process from 100 to 250 tons of waste
a day, depending on the waste characteristics.
During the demonstration, EPA SITE staff conducted a trial burn (three 8-
hour runs) and extensive sampling. All operating conditions during the runs
99
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
were documented. By mid-October, the phase of the removal action involving the
use of the Shirco System was completed. A total of 7,000 cubic yards of waste
material had been processed. A final technical report on the demonstration was
completed in the summer of 1988.
The second demonstration was conducted from October 13 to 16, 1987, at the
Douglasville Disposal Superfund site in Douglasville, Pennsylvania (EPA Region
3), by Hazcon, Inc., of Katy, Texas. A solidification/stabilization process
technology was used in the demonstration.
The Hazcon process blends contaminated soil with cement, pozzolans, and a
proprietary ingredient called chloranan, which aids in the solidification of
organics. Solidified blocks were returned to the excavation hole and will be
monitored for integrity over a 5-year period. A final technical report is
scheduled to be completed in the summer of 1988.
Demonstrations Underway
• American Combustion, Inc. of Norcross, Georgia, completed the
demonstration of the Pyretron, an oxygen-air-fuel burner, which
can be fitted to a conventional rotary kiln. This technology was
demonstrated at EPA's Combustion Research Facility at Jefferson,
Arkansas. Contaminated soil from the Stringfellow Acid Pit site
in Glen Avon, California (EPA Region 9) was processed.
• Shirco Infrared Systems of Dallas, Texas, demonstrated a
portable, one-ton per day, pilot Shirco unit incineration
technology at the Rose Township-Demode Road Superfund site in
Rose, Michigan (EPA Region 5). The one-ton per day unit is
similar to the 100-ton per day unit except for waste capability
and size.
• Demonstration of an in situ vacuum extraction process was completed
at the Groveland Wells Superfund site in Groveland, Massachusetts
(EPA Region 1) by Terra Vac, Inc., of Dorado, Puerto Rico. The
process consists of installing subsurface wells and introducing
a negative pressure gradient through the use of vacuum pumps.
The resulting air-streams that come from the wells are then
extracted and pulled through a separator device and activated
carbon for adsorption of the volatile compounds before the vapor
is discharged to the atmosphere. The process has been applied
to a wide range of volatile compounds, as well as organic and
chlorinated solvents.
• International Waste Technologies (IWT), in conjunction with Geo-
Con, a deep soil mixing equipment company, demonstrated an in situ
stabilization system at the General Electric, Inc., site in
Hialeah, Florida (EPA Region 4). This project demonstrated a
system that treats waste without excavation. The Geo-Con
equipment injects the slurry additive from the bottom of the
shaft of a hollow earth auger. IWT claims the process ti.es up,
or bonds, organic and inorganic compounds, creating
100
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
"macromolecules" in vertical columns that are highly resistant
to acids and other deteriorating factors.
Technologies Selected from First Proposal Solicitation But Not Yet Underway
The following five technologies selected in FY86 were not demonstrated in
FY 1987 either because a site had not yet been selected, the technology was not
yet at full scale, or permitting requirements slowed the process.
• The Basic Extraction Sludge Technology™ was developed by
Resources Conservation Company of Bellevue, Washington. A
chemical plant-like process, it uses differences in chemical
miscibility at different temperatures to break down waste into
three distinct fractions: (1) dischargeable water; (2) reusable
oil and organics; and (3) dry, oil-free solids. The
transportable system was used as part of an EPA removal action
at a Savannah, Georgia, site. The developer collected sampling
and performance data, which ORD is evaluating. If the results
show the unit is able to operate at full scale, a demonstration
will be conducted when a suitable site is selected.
• Detox Industries, Inc. of Sugarland, Texas, developed a
technology involving application of proprietary, naturally
occurring and non-pathogenic organisms for biological degradation
of contaminants. The process involves accelerating the growth
of proprietary microorganisms and inoculating them into the waste
matrix. The result is a systematic biodegradation of the
contaminants over a relatively short time, usually 2 to 4 months.
A SITE demonstration with Detox has been proposed for an EPA
Region 6 Texas Superfund Site. The Agency is assisting the State
of Texas with an investigation of treatment technologies that may
permanently clean up the site.
• A Westinghouse Electric Corporation transportable electric
pyrolyzer unit and a transportable plasma arc unit have also been
selected for demonstration. The transportable electric pyrolyzer
unit transforms a molten mixture of halogens, metals, and other
impurities into a vitrified residue that should be leach
resistant.
The transportable plasma arc unit employs electric arc technology
that uses high temperatures to produce a plasma from pumpable
waste. The waste is reduced in an oxygen-deficient atmosphere
and reforms into hydrogen, carbon monoxide, hydrogen chloride,
nitrogen, particulate carbon, and carbon dioxide. Currently,
both units are undergoing development testing at Westinghouse's
southwestern Pennsylvania facility. Once these units are ready
for demonstration, EPA will select a Superfund site.
• A Pyrolysis Systems, Inc. plasma arc unit designed for thermal
destruction of contaminants was also selected. This smaller
plasma arc unit, owned by the State of New York, was intended to
101
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
treat dioxin-contaminated sludge from the Love Canal site. In
January 1988, New York State advised EPA that it was withdrawing
from the program due to contractual support problems with
Pyrolysis Systems.
• A circulating fluidized bed combustor from Ogden Environmental
Services was selected for demonstration. This combustor operates
at a higher velocity airflow and produces a much higher
combustion efficiency than a conventional fluidized bed. The
unit employs simultaneous limestone injection that captures the
acid gases and eliminates the need for a scrubber. The unit can
recover heat as steam, electricity, hot water, or hot air. EPA
and the State of California planned to use this combustor at
Ogden1s facility near San Diego, California, to run treatability
tests on several Superfund wastes. EPA was to evaluate these
tests under the SITE program.
EPA and the State of California issued the necessary permits for
operation of the facility. The City of San Diego, however,
declined to issue a local use permit. Currently, EPA is working
with Ogden to find a site on which to demonstrate a transportable
unit it has developed.
Plans for Fiscal 1988
EPA has chosen 10 technologies to be demonstrated at Superfund sites from
among the proposals submitted in response to the second solicitation for
proposals. While the first solicitation proposals consisted mainly of various
thermal processes, these 10 technologies are primarily biological and
solidification/ stabilization processes. The EPA Regional offices have
nominated Superfund sites for the 10 new technologies, and final site selections
were made in FY88.
122 Measurement and Monitoring Techniques Development Program and
Technology Transfer Program
Two additional components of the SITE program were developing during fiscal
1987: the Measurement and Monitoring Techniques Development Program and the
Technology Transfer/Clearinghouse Program. Activities related to these two
components are described below.
The Measurement and Monitoring Techniques Development Program has four
goals:
• To assess the extent of contamination at a site;
• To supply data and information to determine the effect
on human health and the environment;
• To supply data to select appropriate remedial action;
and
102
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
• To monitor the success or effectiveness of the selected
remedy.
Through the Environmental Monitoring Systems Laboratory (EMSL) in Las
Vegas, Nevada, EPA has developed the following monitoring/measurement
technologies.
• Immunoassays for toxic substances; and
• Fiber optic sensing for in situ analysis at Superfund sites.
In the immunoassay program in FY87, the Agency participated in the
development and evaluation of a monoclonal-antibody-based immunoassay for
pentachlorophenol. Under the fiber optics program in FY87, resources have been
used to improve the fiber optic sensor for chloroform. The latest modifications
will allow field measurement of chloroform concentrations in soil gases above
contaminated ground water at lower levels than currently used in field methods,
i.e., portable gas chromatography.
123 Technology Transfer/Clearinghouse Program
Recognizing that access to treatment information is essential to the
acceptance and use of alternative technologies, the SITE program has developed
a Technology Transfer/Clearinghouse Program that will collect, synthesize, and
disseminate technology performance data. EPA will document SITE demonstration
results in reports to be made available to Federal, State, and private cleanup
managers and other interested parties. Existing Agency operations will be
utilized to implement clearinghouse operations, e.g., the RCRA/CERCLA hotline,
the OSWER Technology Transfer Bulletin Board, and the EPA library's Hazardous
Waste Collection.
The clearinghouse has three components:
• A Hotline provides callers with up-to-date information
on SITE projects, demonstration schedules, and the
availability of the results, and also refers callers
to other sources of information.
• An electronic bulletin board, part of a planned
computerized data base network, provides summary
information on the SITE projects, demonstration
schedules, and results. Currently, this bulletin board
is available only to Federal and State hazardous waste
cleanup personnel.
• A collection of reports, journals, and other documents
is housed in the EPA library's Hazardous Waste
Collection. This collection is available at EPA's 10
Regional and five laboratory libraries. The
bibliographic data base is accessible using a personal
computer. SITE documents will be added as they become
available.
103
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
EPA is in the second phase of the clearinghouse implementation and plans
to include pertinent data generated by other Agency programs, such as RCRA trial
burn data and ORD's water treatability data base, and other Federal agency and
State hazardous waste cleanup projects.
73 Treatability Studies
Treatability studies are used to evaluate the potential effectiveness of
a technology (or series of technologies) in treating Superfund wastes at an NPL
site. The studies are conducted as part of some RI/FSs at NPL sites, with cost
and reductions in waste volume, toxicity, or mobility the primary factors
influencing an initial selection. For example, the results of a treatability
study will indicate how effective a given technology will be in treating
contaminated soils. If the technology is found effective, it may be proposed
as one of the several remedial alternatives and selected as the final remedy.
Some remedies selected during fiscal year 1987 involved the use of
treatment technologies based on information from preliminary treatability
studies collected during the RI/FS. In these cases, a full treatability study
was deferred until the remedial design phase of the project. The number of
treatability studies conducted during RI/FSs is expected to increase in fiscal
1988. Expanding the application of existing technologies complements the
development of new technologies, and increases the number of waste treatment
alternatives potentially available to Superfund actions.
Special Treatability Studies
At the request of the Superfund program, the Office of Radiation Programs
(ORP) is conducting two special treatability studies on radium contaminated soil
from several Superfund sites. The studies are designed to develop and evaluate
several technologies for possible use in treating radium-contaminated soil at
the Montclair and Glen Ridge Superfund sites. Two major projects are underway,
the Volume Reduction/Chemical Extraction (VORCE) project and the Volume
Reduction Research project (VORRP).
The VORCE project consists of several studies examining methods to
significantly reduce the quantity of radioactive soil that must be disposed of
or shipped offsite. Topics being studied include: the general chemistry of
soils; the distribution of radioactivity in soil particle size fractions; the
mineralogy of particles in selected high-radioactivity fractions; treatment of
larger particles, primarily with dilute washing solutions; and treatment with
complexing agents or high-concentration acid solutions (leaching) to remove
radioactivity. Soils from two New Jersey sites are being used for this project,
which is expected to result in a demonstration program project in mid-1989. The
studies are being done at ORP's Eastern Environmental Radiation Facility.
VORRP uses the "Tru Clean" process and equipment, a Department of Defense
owned jig system, for separating soils by size and specific gravity. The
project is being managed by ORP and operated at the Department of Energy Nevada
Test Site. Contaminated soil from three NPL sites is being used for the VORRP,
which is expected to be completed by mid-1988.
104
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
7.4 Superfund Technology Support Project
An essential complement to the Increased development of new permanent
treatment technologies is an information transfer/technical assistance program
to encourage field use of these new technologies. EPA initiated such a program
in FY 1987: the Superfund Technology Support Project. The project is designed
to provide EPA personnel, State Superfund organizations, potentially responsible
parties, and the public with technical assistance, demonstration, training, and
information about the best demonstrated technologies for application at
Superfund sites as rapidly as possible. The project has six components:
• Contractor Assistance;
• A High Technology Demonstration and Training;
• An Information Clearinghouse;
• Rotational Assignments (to enable EPA personnel to
familiarize themselves with all aspects of Superfund);
• Site Technology Reviews; and
• A Superfund Technology Hotline.
The EPA laboratories at Las Vegas, Nevada, Ada, Oklahoma, and Cincinnati, Ohio,
were given $750,000 each to launch the Technology Support Project. It is
expected that four EPA laboratories will be funded under the Technology Support
Project in FY88.
7.5 International Survey
To ensure that Superfund sites are treated using the best technology
available world wide, EPA has completed an international survey of treatment
technologies. A report on the results of the survey, The Assessment of International
Treatment Technologies Available for Superfund Application, was prepared and will be available
to Regions and States. The report identifies technologies for possible
licensing and use in the United States. These technologies were evaluated on
site during FY 1988.

8.0 TECHNOLOGICAL AND HEALTH-RELATED RESEARCH AND DEVELOPMENT
AND TECHNICAL ASSISTANCE
8.1 CERCLA Authority Related to Research and Development as Amended by SARA
CERCLA authorizes a comprehensive Federal research program, with the
overall objective of improving the scientific and technical basis of the
Agency's risk management decisions at Superfund sites. In FY87, several new
research programs were begun that address the need for better assessment of
health risks posed by hazardous substances and the need for treatment
technologies that provide permanent protection of human health and the
environment. Technical support programs that were developed under the original
CERCLA were also continued.
Superfund research, development, and demonstration activities at EPA and
other Federal agencies were responsive to several CERCLA provisioas:
• Section 209 of SARA amends CERCLA by adding section 311(b),
which authorizes an EPA program of research, evaluation,
testing, development, and demonstration of alternative or
innovative treatment technologies that may be utilized in
response actions to achieve more permanent protection of
human health and welfare and the environment.
• Section 311(c) authorizes EPA to conduct and support,
through grants, cooperative agreements, and contracts,
research on the detection, assessment, and evaluation of the
effects and risks to human health from hazardous substances
and detection of hazardous substances in the environment.
• Section 311(d) authorizes EPA to establish up to 10
hazardous substance research centers to conduct research and
provide training on the manufacture, use, transportation,
disposal, and management of hazardous substances and to
publish and disseminate the results.
• Section 104(i) authorizes a research program at ATSDR to
develop appropriate methods to determine the health effects
of hazardous substances frequently found at Superfund sites.
The research will also seek to develop methods to determine
the health effects of such substances in combination with
other substances (complex mixtures).
• Section 311(a) authorizes a program at NIEHS to develop
advanced techniques for detection and evaluation of the
effects of hazardous substances on human health; methods to
assess the risks to human health presented by hazardous
substances; methods and technologies to detect hazardous
substances in the environment; and basic biological,
chemical, and physical methods to reduce the amount and
toxicity of hazardous substances.
106
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
• Amended Title 10 of the United States Code (Chapter 160,
Environmental Restoration) authorizes the Secretary of
Defense to carry out a program of research, development, and
demonstration with respect to hazardous waste. The
Department of Defense program is directed towards a
reduction in the quantities of hazardous wastes; methods for
treatment, disposal, and management (including recycling and
detoxification); identification of more cost-effective
cleanup technologies; collection of toxicological data and
methodology on risk of exposure; and the testing,
evaluation, and field demonstration of innovative
technologies.
Substantial coordination has occurred between EPA and the two Federal
departments authorized to conduct technology research under CERCLA: HHS and
DOD. A concerted effort has been made to ensure an integrated Federal research
program and to avoid duplication of effort.
8.2 Technology Research, Development, and Demonstration
82.1 Treatment Technology Evaluation
Site-Surface Treatment
For the treatment of site surface contamination, both surface equipment
and in situ treatment technologies are being evaluated. In FY87, four major
processes were addressed: (1) extraction processes that separate contaminants
from the media in which they are found, with emphasis on development of field
systems that minimize costs; (2) immobilization processes that permanently bind
a contaminant to the existing medium or to a modified medium; (3) detoxification
processes that degrade or destroy contaminants using biological, chemical, or
thermal techniques; and (4) delivery and recovery processes that are needed for
both in situ and surface treatment.
Major FY87 accomplishments included: (1) the completion of a handbook on
treatment of hazardous waste leachate; (2) evaluation of the Mobile Soils
Washing System; (3) additional design modifications for the EPA Mobile
Incineration System; (4) preparation of the EPA Mobile Carbon Regenerator for
reactivating spent carbon from physical/chemical treatment systems; and (5)
development of data on CERCLA waste treatment for use in determining the best
demonstrated available technology under RCRA.
Ground-Water Restoration
Two alternatives exist for cleanup of contaminated ground water: pump-
treat- recharge and in situ treatment. Limited research is being conducted on the
conventional water treatment technologies used to treat ground water that is
pumped to the surface, but this research area may be reexamined as new
technologies and approaches are identified. A low level of research also
continues to examine in situ ground-water restoration techniques.
107
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
8.2.2 Personnel Protection
Personnel protection research is directed at specific safety and cost-
efficiency concerns related to use of chemical-protective clothing, equipment,
and procedures. Research priorities for FY87 and FY88 were established at a
workshop attended by EPA Regional offices, EPA Occupational Health and Safety
staff, and Superfund contractors. In FY87, tests were conducted on techniques
for in-the-field assessment of clothing degradation, decontamination and reuse
procedures, use of personnel coolers to reduce worker heat stress, problems with
disposable clothing, and use of robotics and automation.
Interagency coordination is enhanced by a Memorandum of Understanding among
EPA, the Coast Guard, the National Institute for Occupational Safety and Health,
the Occupational Safety and Health Administration, and the Federal Emergency
Management Administration.
823 Superfund Research Grants
In FY87, EPA established a university research grant program to conduct
applied research relevant to Superfund site assessment and cleanup. Grant
applications were solicited in two areas: "Measurement and Monitoring Methods
for use at Superfund Sites" and "In Situ Treatment of Hazardous Waste." In the
monitoring area, 20 applications were received and 9 projects were selected for
funding, including development of rapid screening techniques, more comprehensive
testing protocols, and detection methods that can be used with field-portable
equipment. In the treatment area, 46 applications were submitted and 5 were
selected for funding. A range of treatment techniques are involved, including
biological treatment that focuses on chlorinated organic compounds, polyaromatic
hydrocarbons, and arsenicals. EPA funded five additional applications received
in the general grants program.
83 Health-Related Research and Development
CERCLA authorizes significant new health research programs in EPA and HHS.
Although the statute does not clearly differentiate among research areas and
agencies in the health research area, a broad research agreement was reached on
the scope of each agency program. The EPA research program will focus on the
development and evaluation of toxicological test methods, exposure assessment
methodology, and risk assessment and characterization techniques. The ATSDR
will conduct research related to its health assessment responsibilities under
CERCLA. The NIEHS will support multidisciplinary biomedical research through
grants to universities.
83.1 EPA Health Effects, Risk Assessment, and Detection Research
The Program's objective is to improve the scientific capability for
detecting, assessing, and evaluating the effects on and risks to human health
from hazardous substances, as needed for Superfund removal and remedial cleanup
decisions.
The EPA research program has been developed cooperatively within ORD and
between ORD and OSWER. It has several components organized conceptually in a
108
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
matrix. Three of these components correspond to the steps in the Public Health
Evaluation Process used by the Office of Emergency and Remedial Response:
Toxicity Assessment
Key toxicity data will be developed for use in risk assessment, including
rapid response toxicity testing and field screening of priority compounds,
evaluation of the toxicity of incinerator and other treatment residues,
evaluation of PCB and PCDF carcinogenicity, and human reproductive risks from
chemical mixtures.
Exposure Assessment
To improve the confidence and accuracy of human exposure estimates at
CERCLA sites, this research will characterize parameters needed for exposure
assessment, validate existing models, and develop approaches for assessing
multimedia exposure and integrating exposure assessment.
Risk Characterization
Methods for characterizing health risks and environmental effects of
chemical mixtures will be developed and assistance will be provided in site
assessment.
The other components correspond to major research themes of priority
interest to ORD and OERR:
Internal Dosimetry
To better predict delivered dose, two areas of research will be emphasized:
1. Pharmacokinetics
This initiative will better predict the bioavailability of chemicals.
Research will: define rates of skin, inhalation and oral absorption;
characterize pharmacokinetic parameters of uptake, distribution, and metabolism;
develop physiologically based pharmacokinetic models for multiple routes of
exposure and for multiple compounds; and identify sensitive subpopulations.
2 . Biomarkers of Exposure and Effect
This initiative will focus on methods for measuring dose through different
biologic assays, including a variety of somatic (mutagenicity) and germinal
markers (sperm measures) as well as the application of markers to epidemiologic
methodologies to improve sensitivity and specificity for human disease
endpoints.
Chemical Mixtures
Focus will be on developing toxicological models to predict interactions,
identifying classes of contaminants that may yield additive, synergistic or
109
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
antagonistic responses, and developing statistical methods for analyzing high-
dimensional data sets.
Noncancer Health Effects
Reproductive toxicity is a critical endpoint of interest for OERR and will
be the initial focus. Research will develop sensitive test methods for
detecting effects on male and female reproductive systems, and biological
markers as early indicators of exposure to chemical mixtures. Additional
emphasis is being placed on neurotoxic endpoints with development of new and
more sensitive in vitro and in vivo endpoints.
The research projects vary in length from two to five years. Annual
progress reports or program reviews will be prepared for these projects.
8.3.2 Agency for Toxic Substances and Disease Registry Research and Development Program
The ATSDR research program focuses on assessing the relationship between
exposure to toxic substances and resulting human health effects, and also on
effective ways to inform the public of health risks.
Epidemiologic and Pilot Studies
An epidemiologic study is the evaluation of a specific hypothesis
concerning the relationship between an exposure to a hazardous substance(s) and
a health outcome in a defined population. All studies in FY87 were conducted
by the Center for Environmental Health and Injury Control or by the National
Institute for Occupational Safety and Health, of the Centers for Disease
Control.
Fifteen epidemiological studies were conducted or in progress on dioxin,
PCBs, lead, arsenic, volatile organic compounds, and other substances. Also,
nine pilot studies, which are used to determine if a comprehensive
epidemiological investigation is warranted, were completed in FY87, and five
additional pilot studies are in progress.
Health Surveillance Systems
A health surveillance is the periodic medical screening of a defined
population for a specific disease or biological markers of a disease, for which
the population is at significantly increased risk. The surveillance system
should include a mechanism to refer to for treatment of those individuals who
screen positive for the disease.
State agencies operated four health surveillance systems in FY87 to
determine the impact of hazardous substances in the environment on: (1) chronic
diseases; (2) developmental disabilities; (3) low birthweight and adverse
reproductive outcomes; and (4) tracking workers previously employed, by the Drake
Chemical Company plant in Lock Haven, Pennsylvania, for bladder cancer.
110
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Toxicological Profiles and Testing Needs
CERCLA section 104(i)(2)(A) requires publication of a priority list of 100
hazardous substances found at NPL sites that pose significant human health
risks. ATSDR and EPA published the list of the first 100 priority hazardous
substances in a Federal Register notice (52 FR 12866) and proposed guidelines for
developing the first 25 Toxicological Profiles, effectively meeting the April
17, 1987 deadline. On October 15, 1987, the agencies published 25 draft
toxicological profiles for EPA and they are now undergoing public comment.
A toxicological profile involves an analysis of available toxicological and
epidemiological data to determine health effects from exposure to a substance.
The profile will determine if there are adequate data to set levels of exposure
that cause health risks, and if not, will identify toxicological tests necessary
to determine that level. EPA and the Hazardous Waste Information Evaluation
Subcommittee of HHS nominated 50 chemicals and several chemical mixtures to the
National Toxicology Program (NTP) for toxicological testing. The NTP initiated
testing of the chemicals, using Superfund monies, to fill gaps in information
about the health effects of the chemicals.
Human Exposure Assessment
To determine the baseline amount of soil that children normally ingest, a
human exposure assessment study applied standard formulae to measurements of
trace elements found in the stool specimens of small children. This study will
support development of human exposure assessments, especially among children
residing near sites that have contaminated soil.
Information Dissemination Research
ATSDR is developing, in collaboration with the National Library of
Medicine, an artificial intelligence expert system for use in emergency response
situations. The objective of the system is to provide assistance to emergency
responders to verify, retrieve, and integrate information, to "reason" in some
fashion, to make choices, and to build a precedent file of experiences. The
system will also be used to facilitate training.
Clinical Toxicology
A wide range of clinical toxicological research was conducted in FY87 on
both organic and inorganic toxicants, with specific programs to study the
effects on genes, the liver, the immune system, and the kidney.
Health Education Research
During FY87, ATSDR supported research with the National Academy of
Sciences, National Research Council, on environmental toxicology and
environmental epidemiology, including a project on risk perception and
communication.

Progress Toward Implementing Superfund: Fiscal Year 1987
8.4 Technical Assistance Provided in Fiscal Year 1987
8.4.1 Chemical Fate, Transport, and Ecological Effects
During FY87, ORD provided technical assistance to EPA Regional offices and
the Environmental Response Team, including: (1) application of a bioassessment
protocol to determine bioavailability of hazardous substances in site samples;
(2) evaluation of the efficacy of various disposal scenarios for contaminated
marine sediments; (3) evaluation of ground-water plume movement arid biological
stabilization of subsurface contaminants; (4) assessment of contaminant uptake
by fish in the Great Lakes; and (5) assistance to other Federal agencies with
waste problems at specific Federal facilities.
8.42 Site Risk Assessments
The Office of Research and Development provided assistance to EPA Regional
offices and the Office of Waste Programs Enforcement on the assessment of
exposure, health effects, and risks. ORD provided Endangerment Assessments on
20 sites. A group was established to provide review of risk assessments
prepared by the EPA Regional offices and to serve as a focal point for obtaining
risk assessment information.
8.43 Chemical Assessments
In FY87, ORD began work on 50 Health and Environmental Effects Documents;
15 were completed. ORD assisted ATSDR in preparing Toxicological Profiles. In
addition, 12 rapid response health assessments on specific chemicals were
provided for use in emergency situations. RQ documentation for carcinogenicity
and other chronic health effects were prepared for 50 chemicals and wastes, in
addition to draft RQ documentation for 191 suspected carcinogens on the original
CERCLA hazardous substances list. Chronic toxicity profiles were prepared for
74 additional chemicals.
8.4.4 Engineering Reviews and Assistance
Engineering staff served on technical advisory committees, reviewed site
assessment and feasibility plans, and advised on engineering issues. A report
was completed on data requirements for remedial action technology screening,
evaluation, design, and construction. In concert with several Regional offices,
EPA developed engineering cost models that will improve cost estimates of
remedial action alternatives. Regional offices were provided with engineering
assistance for approximately 35 sites, including the feasibility of using mobile
treatment systems for specific cleanups.
8.4.5 Monitoring Support
Monitoring technical support was provided to EPA Regions and the National
Enforcement Investigation Center on more than 400 sites. Remote sensing,
including topographic mapping and aerial imagery was used to locate old or
buried contamination sources and to create topographic maps. Approximately 30
maps and 400 images were provided in FY87. Advice on the use of geophysical
tools, such as resistivity, magnetometry, ground-penetrating radar, and other
remote sensing devices, was provided in response to specific requests, as was
112
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
assistance on the proper design and quality assurance for sampling protocols.
Performance of the EPA Regional laboratories was evaluated through the use of
reference materials and the review of laboratory data.

9.0 EPA AND AGENCY FOR TOXIC SUBSTANCES AND DISEASE REGISTRY
HEALTH-RELATED ACTIVITIES
9.1 Overview of the Health Assessment Program
To clearly delineate the nature of its activities, the Agency for Toxic
Substances and Disease Registry has established the following definitions for
three of its key functions:
• The ATSDR health assessment is the evaluation of data and
information on the release of toxic substances into the
environment in order to assess any current or future impact
on public health, develop health advisories or other health
recommendations, and identify studies or actions needed to
evaluate and mitigate or prevent human health effects.
• The ATSDR health consultation is a response from ATSDR to
a specific question or specific request for information
about a toxic substance or a facility affected by a toxic
substance. A health consultation is a more limited response
by ATSDR than what is provided by a health assessment.
• The ATSDR health advisory is a communication from the ATSDR
Administrator to the EPA Administrator that states ATSDR1s
concern that a public health threat exists that is of such
importance and magnitude that EPA should intervene
immediately. ATSDR issued no health advisories in FY87.
There are purposeful differences between ATSDR's health assessments and
EPA's risk assessments. The former are usually qualitative and site-specific
and focus on medical and public health perspectives. However, EPA risk
assessments are quantitative and use statistical and biological models to
calculate numerical estimates of current and potential risk to human health.
EPA's risk assessments may also address environmental effects.
92 Progress in Fiscal Year 1987
In FY87, ATSDR established, as one of its primary goals, the use of health
assessments to meet as many public health needs as possible. Toward this end,
ATSDR began the following activities in FY87 and continued these activities
through FY88:
• Reviewing health assessment data gathered through such means
as exposure surveys, epidemiological studies, exposure
registries, and health surveillance to determine the need
for public health followup;
• Reviewing health assessment data to identify gaps in
knowledge (e.g., toxicity information) to guide research
efforts;
• Establishing closer working relationships with State and
local agencies to obtain health-related data not previously
114

Progress Toward Implementing Superfund: Fiscal Year 1987
supplied to ATSDR and to support State efforts in addressing
the public health issues associated with toxic substances;
• Developing a computer-based information system to store and
manage the health assessment data base; and
• Exploring the effectiveness of computer models and graphics
in research related to health assessment activities.
Health Assessments
ATSDR published, in the Federal Register, procedures for requesting a health
assessment. These procedures include minimum requirements for a petition. In
addition, ATSDR and EPA jointly issued a procedural manual on conducting health
assessments. The manual is designed to integrate health assessment provisions
of CERCLA into the remedial program.
Health assessment-related accomplishments include:
• Sixty health assessments of NPL sites in 28 States;
• Forty-five health assessments of non-NPL sites in 21 States;
• One health assessment as a result of an individual's
petition of ATSDR; and
• Cooperative agreements were awarded to Colorado, Florida,
Iowa, Massachusetts, Michigan, Minnesota, New Hampshire, New
Jersey, New York, South Carolina, and Wisconsin, to assist
them in building capacity to perform health assessments.
Health Consultations
There were 1,467 health consultations completed in 50 States and in Puerto
Rico, the Virgin Islands, the District of Columbia, American Samoa, Guam, the
Trust Territory of the Pacific, the Marshall Islands, Palau, Ponape, Quebec, and
Mexico.

10.0 IMPLEMENTATION OF THE FEDERAL FACILITIES REQUIREMENTS
10.1 Overview of the Federal Facilities Program
CERCLA section 120, added in its entirety by SARA., states that, with few
exceptions, CERCLA provisions, guidelines, rules, regulations, and criteria
apply to facilities owned and/or operated by the Federal government, just as
they do to other facilities. To focus attention on these Federal facilities,
and to implement the CERCLA requirements concerning them, EPA established the
Federal Facilities Compliance Task Force in the Office of Waste Programs
Enforcement (OWPE). The Task Force works with EPA Headquarters and Regional
offices and States to resolve issues concerning Federal facilities. The goal
of the Task Force is to establish a nationally consistent enforcement program
that recognizes and encourages the full use of EPA and State enforcement tools
to ensure that Federal facilities comply with CERCLA and RCRA requirements.
OSWER is also creating a division within OWPE to monitor compliance with
environmental laws at Federal facilities. The division will focus on management
of the Federal facilities docket, policy and guidance development, and
compliance monitoring.
102 Federal Facilities Hazardous Waste Compliance Docket
CERCLA section 120(c) requires EPA to establish a Federal Facilities
Hazardous Waste Compliance Docket. The purpose of the docket is three-fold:
• To identify Federal facilities that may be contaminated with
hazardous substances;
• To compile and maintain information submitted to EPA on
these facilities under the provisions of CERCLA section
120(c); and
• To provide a mechanism to make this information available
to the public.
The initial docket was published in the Federal Register on February 12, 1988,
and lists 1,094 Federal facilities; Exhibits 10.2-1 and 10.2-2 illustrate the
numbers of facilities on the initial docket by Federal agency and by EPA Region,
respectively. This docket, available for public inspection, will also contain
notice of all actions taken under CERCLA regarding Federal hazardous waste
facilities and all hazardous substance release notification Information
concerning Federal facilities submitted to EPA under CERCLA section 103 and
under the permitting and activity notification provisions of RCRA sections 3005,
3010, and 3016.
EPA will also furnish information to the public regarding facilities on
the docket. EPA has established information repositories in all 10 Regions.
Each Region will collect the documents submitted by Federal facilities and
organize and index them according to a uniform system. A milestone tracking
system will be developed to indicate each facility's progress in complying with
Superfund and RCRA requirements.

EPA's efforts in establishing the docket in coordination with the other
Federal agencies and departments involved compiling data to produce the initial
docket of Federal facilities and setting up repositories in EPA Regional offices
to hold the collected information. Compiling and verifying the data required
extensive coordination between EPA Headquarters, Regional offices, contractor
staff, and other Federal agencies. EPA expects to publish an updated docket in
the Federal Register every 6 months.
103 Federal Facility Preliminary Assessments/Site Investigations
Executive Order No. 12580 delegates the responsibility for conducting PAs
and Sis at Federal facilities to the Federal agencies that own and/or operate
those facilities. EPA has the responsibility to ensure that these activities
are performed and has provided guidance and training and organized workshops for
other Federal departments and agencies on conducting PA/SIs. To address CERCLA
deadlines, EPA developed a strategy for pre-remedial activities that set an
April 17, 1988, deadline for Federal agencies to submit to EPA a PA report on
each of the facilities listed on the initial Federal facilities docket.
This initial assessment will help determine if a release has occurred or
if there is a significant threat of a release, and whether the facility should
be evaluated for inclusion on the NPL. Thus, the docket is not intended to
serve as an NPL for Federal facilities. When the PA indicated that additional
evaluation of the facility was necessary and the PA data was inadequate to
support an HRS evaluation, EPA requested the responsible agency to provide, by
118
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
April 1988, all the information necessary to perform a full HRS evaluation of
the site. EPA will propose such facilities for inclusion on the NPL if they
meet the established criteria.
10.4 Federal Facilities Proposed for and Listed on the National Priorities List
On July 22, 1987, EPA added 32 Federal facility sites to the NPL (52 FR
27620), the first Federal facilities to be included on the list. One additional
Federal facility was proposed for inclusion on the NPL, pending a complete
review of comments and the resolution of technical and policy issues. Fourteen
additional Federal facilities were proposed for the NPL on June 24, 1988; later
in 1988 a proposal specifically for Federal facilities will be published.
10.5 Federal Real Property Transfer Regulations Under CERCLA Section 120(h)(l)
Anytime the Federal government sells real property at which a hazardous
substance was released, disposed of, or stored for a year or more, the sales
contract must include a notice that discloses the type and quantity of the
hazardous substance and when it was on the property. Additionally, CERCLA
section 120(h)(3) requires any Federal department or agency transferring
federally owned real property to include in the deed a covenant assuring the
transferee that all remedial action necessary to protect human health and the
environment was taken before the transfer, and also that the Federal government
will conduct any remedial action found to be necessary after the property is
transferred.
Section 120 also requires EPA to promulgate regulations on the form and
manner of the notice to be put in sales contracts and deeds. EPA proposed these
regulations on January 13, 1988. Among the proposed rule's key provisions is
the requirement that the contract notice contain the hazardous substance's name
and Chemical Abstracts Service Registry Number, and the time and quantity of its
storage, release, or disposal. The Agency will also propose that the transfer
of some single-family residences acquired through foreclosure by government
agencies such as the Federal Housing Administration and Veterans Administration
be exempted from the notice requirement. Property at which less than 1,000
kilograms of hazardous substances were stored would also be exempt.
10.6 Interagency Agreements Under CERCLA Section 120(e)(2)
EPA, the Department of the Army, and the State of Minnesota signed the
first interagency agreement (IAG) involving a Federal facility, the Twin Cities
Army Ammunition Plant, on August 12, 1987. The final decision on the remedy to
be undertaken at a Federal facility is made jointly by EPA and the responsible
agency, unless there is disagreement, in which case, EPA has authority to make
the decision unilaterally. Agreement on the selected remedy is outlined in an
IAG between EPA and the responsible Federal agency.
EPA views an IAG as a comprehensive document that addresses all hazardous
waste activities that will be conducted at a Federal facility, from the RI/FS
through the implementation of the remedial action. lAGs formalize the procedure
and timing for submittal and review of documents and establish a mechanism to
resolve disputes. lAGs must comply with the public participation requirements
119
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
of GERCLA section 117, and they are enforceable by citizens and States through
citizens suits. Additionally, CERCLA authorizes assessment of civil penalties
against Federal agencies for failure to comply with lAGs.
10.7 Report to Congress on EPA Responsibilities Under CERCLA Section 120(e)(5)
EPA has 14 facilities subject to section 120(e)(5) reporting requirements.
This number differs from the number of EPA facilities listed in Exhibit 10.2-1
due to changes in facility status that occurred after the original Federal Register
notice was published. These 14 facilities are identified in Exhibit 10.7-1.
Section 120(e)(5) requires each Federal department, agency, and instrumentality
to furnish an annual report to the Congress concerning its progress in
implementing CERCLA at its facilities. The report must include information on:
progress in reaching interagency agreements; cost estimates for each IAG; public
comments on lAGs; progress in RI/FSs and RAs initiated at Federal facilities on
the NPL; and progress in RAs at non-NPL facilities.
The Occupational Health and Safety staff of EPA's Office of Administration
and Resources Management is working to prepare the report on these EPA
facilities. At present, these facilities are undergoing PAs; consequently,
there are no RI/FSs or other remedial actions to report as yet.

11.0 MINORITY FIRM PARTICIPATION IN SUPERFUND CONTRACTING
The 1986 enactment of SARA added to CERCLA a new provision, section 105(f),
that requires that the availability of minority businesses be considered in the
Superfund work carried out under contract to the Federal government.
In the fulfillment of this mandate, EPA's Office of Small and Disadvantaged
Business Utilization (OSDBU) has continued and expanded existing programs, begun
new activities, and planned additional efforts to ensure the full and fair
consideration of minority firms for Superfund contracting. EPA meets the
remainder of its section 105(f) responsibilities by describing its minority
contracting program activities and results in this Report.
11.1 EPA Procedures to Identify Qualified Minority Firms
EPA employs a wide variety of procedures to identify minority firms that
may qualify for work as Superfund prime contractors or subcontractors.
Contractors must meet standards of technical and financial ability in order to
qualify for Superfund work. These procedures, which usually involve the
assistance of minority business agencies at the Federal, State, and local level,
are discussed below.
Memorandum of Understanding with the Minority Business Development Agency (MBDA)
One of the tools EPA can use in its implementation of the Superfund program
is a Memorandum of Understanding (MOU) . An MOU is a statement agreed to by two
or more parties (in this case, EPA and another Federal agency) that recognizes
the interrelationship of their two functions and specifies appropriate
interactions between the two parties. EPA is negotiating an MOU with the MBDA,
a unit of the U.S. Department of Commerce, to gain its assistance in identifying
minority business enterprises (MBEs) that may be eligible for work in the
Superfund program. Minority business development centers (MBDCs) , which are
private firms that assist the Federal government in its minority contracting
efforts, will be particularly helpful in this effort. EPA envisions several
ways to use MBDA regional offices and MBDCs to match minority and women's
business enterprises (WBE) with specific Superfund direct procurement needs.
For example, MBDCs can provide technical assistance needed by firms to help them
qualify for Superfund contracting.
MBE Coordinators in EPA Regional Offices
EPA employs MBE Coordinators in each of its 10 Regional offices to act as
liaisons between OSDBU and EPA Regional personnel, State and local officials,
MBDA Regional offices, and MBDCs. Special efforts have been made to apprise MBE
coordinators of the requirements for Superfund minority contracting and how they
may assist EPA's Superfund program officials in complying with these
requirements.
Survey of State and Local Governments
EPA has begun a survey of State and local governments to determine whether
these governments have established goals or objectives for minority firm
participation in government contracting. EPA will use the results of this
122
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
survey, which is targeted for completion in FY88, to inform State and local
government offices of the Superfund minority contracting program. In a related
effort, EPA's Regional MBE Coordinators will solicit information on potential
Superfund minority contractors from State governments in their Regions.
Small Business Administration (SBA) Section 8(a) Program
EPA's Socioeconomic Program Officer will work closely in FY88 with SBA
officials to identify any Superfund contracting needs that may be fulfilled by
minority contractors in the SBA section 8(a) program. The 8(a) program, which
was established by section 8(a) of the Small Business Act, allows SBA to act as
a prime contractor for Federal government contracts and set up subcontracts with
small disadvantaged (minority) firms. The small disadvantaged firms compete for
these subcontracts only against other such firms in the 8(a) program.
EPA Procurement History Files
EPA will undertake a comprehensive search of its Procurement History Files
in FY88 to identify minority firms that have worked on Superfund projects in the
past.
The MBDA PROFILE System
The MBDA maintains a computer-based compilation of data on approximately
31,000 minority firms known as the PROFILE System. The system classifies firms
according to Standard Industrial Classification Code and Zip Code. Minority
businesses listed in another data base, the SBA's Procurement Automated Source
System (PASS), have been extracted from PASS and incorporated into the PROFILE
System. EPA will undertake a search of the PROFILE system in FY88 to identify
potential Superfund minority contractors.
11.2 EPA Efforts to Encourage Participation
Because Superfund contracting opportunities are not always well known, and
because entry into a Superfund contract is voluntary, EPA must publicize the
Superfund minority contracting program in the minority business community, and
must encourage the participation of qualified firms. This subsection describes
the various ways in which EPA brings qualified firms into the Superfund minority
contracting program.
Minority Procurement Conferences
In a collaborative effort with EPA's Procurement and Contracts Management
Division, OSDBU has sponsored several highly successful Minority Procurement
Conferences in various locations throughout the country to help minority
businesses participate more fully in the Agency's competitive procurement
activities. Two of these Conferences were held in FY87; three are planned for
FY88.
MBE/WBE Information Seminars
EPA and State governments co-fund State-run seminars to inform minority
firms of EPA contracting opportunities. Three seminars (one each in Utah,
123
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Florida, and Washington) were held. In FY88, seminars have already been
conducted in Mississippi and New England, and are scheduled for Oregon and New
York.
OSDBU MBE/WBE Training Workshops
OSDBU conducts MBE/WBE Training Workshops for EPA Regional and State
officials; workshops were held in four EPA Regions that involved 23 States and
the District of Columbia. Workshops for the remaining six EPA Regions are
scheduled for FY88. An Annual Workshop for OSDBU Regional MBE Coordinators is
also held.
Minority Business Training
In FY88, EPA will assist the National Association of Minority Contractors
(NAMC) in conducting training programs to prepare potentially qualified minority
firms to compete more effectively for EPA and State prime contracts and
subcontracts. Three weeks of training activities will be conducted in each of
several major cities through a $500,000 contract awarded to NAMC by EPA on
January 14, 1988.
MBDA National and Regional Conferences
MBDA, by agreement with EPA, conducts national and Regional conferences for
MBDCs to encourage minority businesses to participate in the Superfund program.
One national conference and one conference in each MBDA Region are; conducted
each year.
Letters to Other Federal Agencies Participating in the Superfund Program
OSDBU stressed the importance of minority contractors in October 1987
letters it sent to its counterpart OSDBU offices in other Federal agencies
involved in the Superfund program, such as the Army Corps of Engineers. In
order to help ensure that these other agencies comply with section 105(f), EPA
has required them to submit regular, detailed reports on Superfund contracts
they have awarded to minority firms.
Publications on Superfund Participation
EPA issued two publications on contractor participation in Superfund in
FY87: "CERCLA: Getting into the Act," in April 1987, and "Doing Business with
EPA," in August 1987.
113 Participation by Minority Firms in Superfund Contracting
The extent of minority Superfund contracting relative to all Superfund
contracting is shown in Exhibit 11.3-1. As the table shows, minority
contracting accounted for 6 percent of all Superfund contracting on a dollar
value basis. The greatest dollar value of minority firm work on Superfund
projects was obtained through direct procurement by EPA. The types of services
that minority firms provided through direct procurement can be categorized into
three major areas: professional, field support, and construction. Typical
services contracted or subcontracted to these firms are listed below.

CERCLA cooperative agreements (CAs) are contract-type arrangements between
EPA and State government agencies, local governments, and Indian Tribes that
enable EPA to involve these non-Federal governments in response activities at
Superfund sites within their jurisdiction. CAs specify work to be performed and
the funding allocated for the work. Governments with CAs may establish more
specific subagreements, some of which involve minority firms. In FY87, of the
$9,400,000 awarded to non-Federal governments, $2,100,000 in subagreements, or
22 percent, were awarded to minority contractors. These awards ranged from a
low of $350 to a high of $833,345. The services rendered under the
subagreements were primarily professional services such as architectural and
engineering work, and services related to remedial design for Superfund sites.
EPA interagency agreements are similar to cooperative agreements, except
that the former are negotiated between EPA and other Federal agencies, such as
the Army Corps of Engineers. These agencies then allocate specific portions of
their interagency agreements to minority contractors and other contractors.
Interagency transfers of Superfund monies during FY87 amounted to $237,500,000.
Of this amount, $4,600,000 was placed with minority contractors. The range of
minority awards was from $4,755 to $4,200,000. The services provided under
these awards include conference support, automated data processing services, and
services related to the study, design, and implementation of a site remedial
action.
The total $38,000,000 of Superfund program minority firm contracting is
diagrammed in Exhibit 11.3-1 by type: prime contracts; subcontracts; and SBA
8(a) contracts. As shown, 8(a) contracts account for the greatest amount of
Superfund minority contracting, in terms of both the number of contracts awarded
and the dollar value of the contracts.
The data for Exhibit 11.3-1 were obtained from a variety of sources.
Direct procurement figures were obtained from the Federal government's Contract
Information System (CIS) . The total number of awards and the total dollars
awarded through cooperative agreements were obtained through EPA's Grants
Information Control System (GIGS). The number of minority subagreements awarded
and the dollar value of these subagreements were obtained by EPA Regional
offices from Standard Form 334.

Progress Toward Implementing Superfund: Fiscal Year 1987
The total number and dollar value of Interagency Agreements was obtained
from the GIGS. The minority contractors' share of these figures was obtained
from the Federal agency making the award by the use of EPA Form 6005-3. Of the
20 Federal agencies contacted, only two, the Army Corps of Engineers and the
Department of Health and Human Services, reported any use of minority
contractors.

12.0 THE NATIONAL RESPONSE TEAM AND REGIONAL RESPONSE TEAMS
The National Response Team (NRT) and the Regional Response Teams (RRTs)
execute Federal responsibilities in the preparation for and coordination of on-
scene response operations. The NRT, consisting of representatives from 14
Federal agencies, is responsible for- national coordination and planning of
preparedness and response actions. Representatives from the same 14 agencies,
as well as State designees, make up each of the 13 RRTs. The RRTs oversee
regional preparedness planning prior to response and assist in the coordination
and operations of response.
NRT and RRT Accomplishments in Fiscal Year 1987
The NRT promotes Federal preparedness through training coordination,
technical assistance, information exchange, contingency planning, and by
fostering cooperation between the public and private sectors. In particular,
the NRT has assisted EPA with the development of the NCP in accordance with
Executive Order 12580. The NRT helped draft Subpart B of the NCP and reviewed
and commented upon the entire document. In another CERCLA-related area, the NRT
provided the means for the FY89 Interagency Budget Task Force to distribute
CERCLA funds to Executive departments and agencies. Also during FY87, the NRT
established a standing RRT for the Pacific Oceania area.
Established by the NRT in FY87, the following committees have carried out
elements of the NRT's mission:
• The Management Committee developed the FY88 NRT Workplan
and prepared a procedures manual to streamline NRT
operations;
• The Preparedness Committee assisted in the development and
review of the Hazardous Materials Emergency Planning Guide
(NRT-1);
• The Training Committee developed the NRT training strategy;
and
• The Computer Applications Committee began development of a
directory of Federal information resources and other
computer-based tools to enhance preparedness for, prevention
of, and response to chemical incidents.
RRTs
Regional Response Teams, in accordance with their FY87 workplaris, conducted
a variety of preparedness activities, such as simulated response exercises and
training seminars. The RRTs also developed RRT FY88 preparedness workplans
tailored to Regional needs. When requested by Federal on-scene coordinators
during FY87 emergency responses, RRTs were activated to provide information and
technical services.

13.0 EXECUTIVE BRANCH ESTIMATE OF RESOURCES NEEDED TO COMPLETE
SUPERFUND IMPLEMENTATION
13.1 Introduction
CERCLA section 301(h)(l)(G) requires EPA to estimate the resources needed
by the Federal government to complete Superfund implementation. The Agency
interprets this requirement to mean the cost of completing CERCLA1s
implementation through the current authorization (FY91) and beyond. The
preliminary estimate included in this chapter, however, only includes
information up through 1989. Congress provided EPA with $3,964,000,000 in
budget authority for the implementation of CERCLA, as amended, for the three
year period, fiscal 1987 through 1989. The budget authority provided for each
respective fiscal year is:
• FY 1987 - $1,411,000,000
• FY 1988 - $1,128,000,000
• FY 1989 - $1,425,000,000
The actual level of funds obligated in each fiscal year may be slightly less
than the level of budget authority provided. Data on the resources needed
beyond 1989 are in the early stages of development, as part of the 1990 budget,
and thus cannot be included in this Report.
The resources estimate in this chapter is divided between resources needed
by EPA and those needed by other Federal departments and agencies. It is based
primarily upon the responsibilities and duties assigned to EPA and other Federal
departments and agencies by Executive Order 12580, some general assumptions
about the overall size and cost of the Superfund program, and data submitted to
EPA by other Federal departments and agencies. This estimate includes
assumptions about the size and scope of the Superfund program, the nature and
number of response actions, participation by States and private parties, the
increasing use of treatment technologies, and other factors. In the case of
EPA, these assumptions relate to management of the workload already in the
remedial pipeline.
In developing the resource estimate required by section 301(h)(1)(G), EPA
considered several sources:
• EPA Superfund budgets for fiscal years 1987, 1988, and 1989,
including budget requests from other Federal departments and
agencies;
• Data that Federal departments and agencies submitted to EPA
under an approved General Services Administration (GSA)
interagency report control number (IRCN) issued on February
5, 1988 as required under the provisions of 41 CFR 201-45.6
(IRCN 0354 EPA -- Annual);
• The Federal Agency Hazardous Waste Compliance Docket
developed under CERCLA section 120(c) and individual Federal
129
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
department or agency Annual Reports to Congress on Federal
Facilities Implementation required under section 120(e)(5);
• EPA's Report to Congress under CERCLA section 301(a)(1)(C) ,
which is entitled Extent of the Hazardous Release Problem
and Future Funding Needs (December 1984);
• EPA's Annual Report to the Office of Management and Budget:
(OMB) on Pollution Abatement Needs at Federal Installations,
which is submitted under Executive Order 12088; and
• Various EPA information systems, primarily the financial
management system (FMS).
Although these sources will be used for future Reports, the Agency also is
working to identify data requirements, improve data quality, develop cost
estimating methods, and collect additional information. Specifically, EPA is
working to prepare a more complete estimate for the current authorization, in
the out-years of 1990 and 1991, and the unfunded period beyond 1991 by
conducting:
An RI/FS Cost Study
This detailed and comprehensive study is expected to provide information
on completion periods, costs associated with various activities, cost
relationships between NPL EPA-lead and State-lead actions, and other cost
components. The study was completed in fiscal year 1988.
An Analysis of Superfund's Unfunded Liability
This long-term effort will be coordinated with the development of the 1990
budget. In conjunction with the proposal of the NCP and its policies affecting
program direction and scope, EPA should be in a position by fiscal year 1989 to
project a more complete implementation cost estimate.
EPA's ability to project the Federal resource requirement for CERCLA
implementation will improve with the publication of the final NCP and more than
two years of experience implementing CERCLA, as amended by SARA. Better
coordination with other Federal departments and agencies and additional data on
the implementation of the Federal Facilities requirement of section 120 will
also help to improve the estimate.
132 EPA Estimate of Resources Necessary to Complete Superfund Implementation
In estimating the resource requirements of EPA to complete the
implementation of CERCLA, the Agency typically focuses its projections on the
costs of the remedial and removal programs in future years. These two response
program areas are the major components of the Superfund program and account for
the large majority of the Agency's Superfund expenditures. The estimates of
the resource needs for these two program areas are projected for fiscal years
1988 and 1989.
130
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Developing a complete and accurate estimate of the costs to EPA of
completing Superfund implementation is dependent upon a number of factors, many
of which could change in future years. Presently, the most important factors
are:
• Changes in Superfund program policies and procedures -due to
the revised NCP, particularly the cleanup standards
requirements of CERCLA section 121;
• Changes in the remedial program due to the revisions to the
HRS required by CERCLA section 105;
• Changes in the character and size of the CERCLIS inventory
and, as a consequence, the facilities that are added to the
National Priorities List;
• The effects of the long time period required to identify,
develop, select, and construct a remedy, particularly those
using treatment technologies;
• The level of State Superfund program activity;
• The level of potentially responsible party participation in
the program; and
• The nature of and demand for removal actions.
Superfund expenditures support EPA activities in three major categories:
program support, site-related support, and direct site support. Over time, the
distribution of resources among those functions will vary as the program
matures, and with changes in policy, direction, and the inventory and character
of sites. EPA's Superfund budget also supports other Federal department and
agency activities funded from the Hazardous Substance Superfund.
Program Support
In FY87, this category accounted for approximately 12 percent of Superfund
resources, and was used to support:
• Information management;
• Policy and planning;
• General administration;
• Training;
• Community assistance grants;
• Siting capacity grants;
• Office of the Inspector General; and
• Support for other Federal departments and agencies.
Program support resources are used in four principal areas: (1) general
and financial administrative support (24 percent); (2) research and support for
other Federal departments and agencies (25 percent); (3) information management,
policy and planning activities (24 percent); and (4) siting and community
131
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
assistance, EPA Office of the Inspector General support, and miscellaneous other
activities (27 percent).
Site-Related Work
In FY87, this category accounted for approximately 7 percent of Superfund
resources, and was used to support:
• National Response Team and Regional Response Team activities;
• Cost recovery action under CERCLA section 107;
• Health studies and research; and
• Criminal casework.
Site-related work resources are largely accounted for by NRT and RRT
support (36 percent), and preliminary enforcement and cost recovery activities
(41 percent). The remaining 23 percent supports research for program support,
criminal casework, and other miscellaneous activities.
Direct Site Support
In FY87, this category accounted for approximately 81 percent of Superfund
resources, and was used to support activities in two areas:
• Direct Site Work
Removal actions;
Remedial actions;
Pre-remedial/site assessments; and
Engineering and design studies.
• Site Support
Extended remedial actions;
Community relations;
Contract laboratory support;
Contract management;
Enforcement;
Potentially responsible party settlements; and
Superfund Innovative Technology Evaluation (SITE) program.
The bulk of these resources, approximately 77 percent, is; devoted to
removal and remedial actions, including extended remedial actions.
Any improvements which are made in developing a preliminary estimate of
EPA's Superfund implementation resource needs will depend, to a large degree,
on changes involving remedial program costs, cost recovery revenues, and direct
cleanup actions taken by potentially responsible parties.
Potentially responsible parties contribute to the hazardous waste cleanup
effort by undertaking and financing voluntary or enforced remedial activities,
thereby reducing the number of remedial actions requiring government funding.
132
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
EPA is currently developing and implementing policies designed to encourage PRP
cleanups.
132.1 Remedial Program Costs
Remedial actions are currently the single largest category of Superfund
expenditures and are expected to remain so in the future. In order to project
EPA funding needs for the remedial program, several key factors must be
estimated:
• The projected size of the NPL;
• The projected number of RI/FSs, remedial designs, and
remedial actions undertaken;
• The average cost of an RI/FS, RD, and RA; and
• The direct cleanup actions taken by responsible parties.
Exhibits 13.2-1 and 13.2-2 present data on EPA Superfund resource
requirements in workyears and dollars, respectively. Summary data on the
principal elements of EPA's Superfund workload are presented in Exhibit 13.2-3.

approximately $14,804,900 was also transferred to other Federal departments and agencies via site-
specific interagency agreements (lAGs) for support to EPA at Superfund sites. These two sources
provided a total of approximately $66,148,000 or 6 percent of the total obligated Trust Fund amount
of $1,050,749,000.

-------
Progress Toward Implementing Superftind: Fiscal Year 1987
Cost Recovery Revenues
In addition to the direct remedial and removal actions that are undertaken
by PRPs, a portion of the costs of certain Fund-financed response actions will
be recovered from PRPs through enforcement activities. The cost recovery
revenues obtained from PRPs will ultimately reduce the overall costs of both the
remedial and removal programs. In general, it takes about three years from the
time EPA makes an expenditure from the Trust Fund for final site work to the
time these response costs are reimbursed to EPA by PRPs.
The cost recovery rate for remedial expenditures is subject to a range of
possible estimates given varying assumptions about: (1) the probability of
successful litigation; (2) the ability to recover interest costs from
litigation; (3) how many NPL sites will be cleaned up by private parties without
the use of the Fund; and (4) the role of new CERCLA settlement provisions, such
as mixed funding and de minimis settlements. To date, Fund-financed remedial
action generally has been taken at sites where PRPs are potentially capable of
taking on cleanup responsibility. The cost recovery rate for these sites is
likely to be relatively high.
In future years, as the rate of successful EPA enforcement actions
increases, more PRPs are expected to undertake actual cleanups directly. As a
result, more Fund-financed actions may be taken at sites where there are fewer
financially-viable PRPs connected with the sites. The probability of cost
recovery for these sites may be lower than for previous sites.
While the cost recovery revenues obtained from PRPs will reduce the costs
of the two response programs to EPA, the available data for these revenues are
not sufficient to allow for an accurate estimate of the percentage of Fund-
financed remedial and removal costs that will be recovered from PRPs. The
Agency is putting significant effort into improving its cost recovery
performance. The fiscal 1987 cost recovery amount was the highest in the
program's history.
133 Other Executive Branch Department and Agency Estimates of Resources Necessary to Complete
Superfund Implementation
The second element in fulfilling the CERCLA section 301(h)(l)(G)
requirement for this Report is to estimate the resources needed by other Federal
departments and agencies. EPA requested the resource requirement information
from the other Federal departments and agencies under an approved GSA
interagency report control number issued on February 5, 1988, as required under
the provisions of 41 CFR 201-45.6. Although EPA received fairly detailed
information for fiscal 1987, EPA anticipates collection of more comprehensive
information for the fiscal 1988 Report.
The resource needs of the other Executive branch departments and agencies
for Superfund implementation activities are met through two sources:
• Hazardous Substance Superfund (Trust Fund)
137
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Interagency Budget: These funds are transferred to other
departments and agencies by EPA from the Hazardous Substance
Superfund through an interagency budget under Executive
Order 12580.
Site-Specific Agreements: These funds are transferred to other
departments and agencies from the Hazardous Substance
Superfund by EPA through site-specific agreements.
• Individual Federal Department or Agency Budgets
CERCLA-Specific Funds: These funds are budgeted by the
individual departments or agencies specifically for CERCLA
activities and support as part of the President's annual
budget submission.
General Funds: These funds are utilized for CERCLA activities
and support by other departments or agencies and are
obtained from general budget resources or are taken from
resources designated for other programs.
The reported resource needs of other Federal departments and agencies are
summarized in Exhibit 13.3-1. Exhibits 13.3-2 and 13.3-3 present estimates of
CERCLA implementation resource requirements from other Federal department and
agency budgets in dollars and workyears, respectively. Information provided by
other departments and agencies to supplement those numbers is included below.
Department of Defense
Since 1984, there has been an increased emphasis on this Department's
efforts to clean up contamination from hazardous waste sites under the Defense
Environmental Restoration Program. As a sub-element of the Defense Environ-
mental Restoration Program, the Installation Restoration Program's objective is
the cleanup of contamination from past activities in accordance with the
procedures and requirements of the NCP. The preliminary studies and remedial
investigations that have been performed for sites in the past few years under
this program are now leading to the identification of needed response work.
The Department of Defense estimates the total cost of the Installation
Restoration Program work to be between $11,000,000,000 and $14,000,000,000. The
uncertainty in the total funding requirement for this program exists because
there are still many remedial investigations to be completed and many agreements
have not yet been signed with EPA and State agencies.
Department of the Interior
The Fund appropriation under general lAGs for DOI activities will enable
the nine DOI bureaus to participate more effectively on the National Response
Team and will be used for development of State and local contingency plans and
development of procedures for natural resource damage assessments.

The Fund appropriation through general lAGs will enable the USCG to
maintain its response capabilities, ensure that CERCLA financial responsibility
requirements are met, train emergency response personnel using program modules
and simulation drills, staff the CERCLA component of the NRC, and maintain
chemical information systems and records of characteristics for certain
chemicals.
The Department of Transportation estimates that it will use 1988 funding
from its department budget for the USCG and the Research and Special Programs
Administration to completely fulfill their Superfund responsibilities. This
will include Superfund cleanup projects at USCG and Federal Aviation
Administration (FAA) facilities as well as third party liability costs as a
result of the involvement of the Maritime Administration as a de minimis
potentially responsible party at a nuclear waste site in Maxey Flats, Kentucky.
In addition, DOT projects that it will require funding for third party liability
costs from 1989, and perhaps beyond, resulting from the Maritime
Administration's involvement at the Maxey Flats site.
141
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
General Services Administration
Within the 1988 budget request estimate, GSA proposed allocating $100,000
for one Superfund project at its facilities. In addition, GSA is currently
involved in five Superfund site investigations in which it is a PRP. As a
result, GSA estimates that it will incur third-party PRP costs in future years.
Department of Commerce
General IAG monies will allow NOAA to provide and evaluate updated field
monitoring methods for sampling and analyzing contaminants discharged into
marine environments; develop computerized contingency plans for selected ports;
provide updated protective equipment; and participate on Regional Response
Teams. The resource estimates do not include resources necessary to meet NOAA's
role as a Federal trustee for natural resources.
Department of Justice
The FY88 resources for the Department of Justice under general lAGs
represent an increase from 1987 for an expanded Superfund caseload and the
operation of a system that provides automated data support for complex cases.
Department of Labor
Funds appropriated under general lAGs will allow OSHA to continue to
provide EPA and other response personnel with technical assistance in protecting
workers at Superfund sites, implementing the worker safety program at Superfund
sites, and supporting the National and Regional Response Teams.
Federal Emergency Management Agency
Funds appropriated under general lAGs for FEMA's ongoing activities will
enhance State, local, and Federal emergency preparedness and administrative
support. These funds will be used for FEMA's support of the Regional Response
Teams and will provide management support and oversight for temporary and
permanent relocations. Funding for temporary or permanent relocation activities
will be provided from resources under EPA's Hazardous Substance Response
program.

Progress Toward Implementing Superfund: Fiscal Year 1987
14.0 OTHER EPA ACTIONS TO IMPLEMENT CERCLA
EPA undertook several actions to implement provisions added to CERCLA by
SARA to address particular issues.
14.1 Implementation of CERCLA on Indian Lands
Section 207(e) of SARA amended CERCLA to add a new section 126 on Indian
Tribes. In accordance with the mandate that EPA treat Indian Tribes as States,
the Agency is planning to award cooperative agreements to Tribes so that they
may conduct response actions. EPA is developing an administrative regulation
that will establish the requirements Indian Tribes must satisfy in conducting
response actions with EPA funds.
Study of Hazardous Waste Sites on Indian Lands
Section 126(c) requires the President to "conduct a survey, in consultation
with the Indian Tribes, to determine the extent of hazardous waste sites on
Indian lands. Such survey shall be included within a report which shall make
recommendations on the program needs of Tribes under this Act, with particular
emphasis on how Tribal participation in the administration of such programs can
be maximized. Such report shall be submitted to Congress along with the
President's budget request for fiscal year 1988." EPA submitted this Report to
Congress on November 6, 1987.
The Report is based largely on data from an EPA-funded survey completed in
July 1985 by the Council of Energy Resource Tribes (CERT) in consultation with
Indian Tribes. The CERT survey was limited in scope and extended only to a
sample of Indian lands. Because of the brief time between the enactment of SARA
in October 1986 and the date in early 1987 by which submittal of this Report
was required, EPA did not feel it was possible to conduct a comprehensive survey
of hazardous waste sites on Indian lands.
The Report: (1) provides background on the Superfund program and explains
the special status accorded Indian lands under the Federal system; (2) describes
the approach and data sources used for the report; (3) presents findings from
these data sources on the extent of the hazardous waste site problem on Indian
lands; and (4) presents recommendations on program needs of Indian Tribes and
the Agency's commitments to address those needs. A brief summary of the
Report's findings and recommendations follows.
An EPA-funded survey that CERT completed in 1985, in consultation with
Indian Tribes, included 1,196 reports of potential hazardous waste generators
and sites on or near 25 selected Indian reservations. This sample represents
about 10 percent of the 278 Federal Indian reservations. Data from supplemental
sources, including discussions with Tribal representatives and the Department
of the Interior's Bureau of Indian Affairs, confirm that there are potential
hazardous waste sites on Indian lands in need of investigation.
Analysis of the data suggests, however, that the number of potential sites
requiring investigation on the 25 reservations is significantly lower than the
1,196 reports in the CERT survey. Over half of the reports (645) are derived
143
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
from an EPA data base of active hazardous waste generators and waste management
facilities. In addition, sites near but not on reservation land were included
in the survey. EPA's inventory of potential hazardous waste sites due for
assessment under the Superfund program already includes many (467) of the
reports in the CERT data base.
Based on these findings, the following recommendations were offered:
• EPA will conduct preliminary assessments and, if necessary,
site inspections of potential hazardous waste sites on
Indian lands using the Agency's Superfund program resources,
unless a Tribe is willing and able to conduct the
assessments;
• EPA will rely on its own response infrastructure to plan and
conduct response actions wherever needed on Indian lands;
and
• Through education and outreach programs, EPA will heighten
Tribal understanding and awareness of hazardous waste site
problems and provide information on Tribal participation in
the Superfund program.
142 Love Canal: Habitability and Land Use Study
Section 312(e) of CERCLA requires the Administrator to conduct a study to:
• Assess the risks associated with inhabiting the Love Canal
Emergency Declaration Area (EDA);
• Compare the level of hazardous waste contamination in the
EDA to that present in other comparable communities; and
• Assess the potential uses of the land within the EDA,
including but not limited to residential, industrial,
commercial, and recreational uses, and the risks associated
with such potential uses.
As early as November 1983, the New York State Department of Health (DOH)
and the U.S. Department of Health and Human Services, Centers for Disease
Control (CDC), as members of the Love Canal Technical Review Committee, were
asked to develop habitability criteria applicable to the EDA. To assist in
developing such criteria, DOH and CDC sought the opinions and recommendations
of 10 distinguished scientists representing a variety of disciplines.
After evaluating several approaches to determine habitability of the EDA,
the scientific advisors recommended using a combination of relevant Federal and
New York standards, criteria, or guidelines, and comparing levels of Love Canal
indicator chemicals from EDA neighborhoods with levels of these chemicals from
similar neighborhoods that are not near a chemical landfill. The views and
opinions of these advisors were considered in a document prepared by CDC and DOH
entitled Proposed Habitability Criteria for the Love Canal Emergency Declaration Area.
144
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
A comprehensive sampling program is the next step that will be carried out
as part of the full-scale habitability and land use study; the results will help
determine the habitability of the EDA. In addition, the results will be
provided to and discussed with individual homeowners as soon as they become
available; and further investigation will be undertaken, if necessary.

EPA AND EXECUTIVE BRANCH IMPLEMENTATION
OF CERCLA AS AMENDED BY SARA
The Superfund Amendments and Reauthorization Act of 1986 (SARA) was passed
by the Senate and House of Representatives on October 3 and 8, 1986,
respectively, and signed by the President on October 17, 1986.
Section 115 of CERCLA authorizes the President to delegate authorities for
executing the Act. In response to the SARA amendments to CERCLA, the President
issued Executive Order 12580 on January 23, 1987, delegating authorities and
assigning duties to various executive departments and agencies. Primary
authority and responsibility for carrying out the Superfund program was assigned
to the Administrator of EPA.
Other organizations, departments, and agencies received specific authorities
in the Order, e.g., the National Response Team (NRT) plays a role in revision
of the National Contingency Plan (NCP) and other specified regulatory and
response activities; the Coast Guard generally oversees response in the coastal
zone, Great Lakes, ports and harbors; and the Agency for Toxic Substances and
Disease Registry (ATSDR) performs various health assessment functions. Executive
Order 12580 also revoked the previous Order, No. 12316 of 1981, which had
delegated authorities vested in the President by the original Superfund
legislation of 1980.
148
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
EPA Organization and Operations for CERCLA Implementation
The Administrator signed final internal EPA delegations of authority on
December 11, 1986, and on August 14, and September 13 and 21, 1987.
Following delegation from the President, the EPA Administrator may retain
all authorities assigned to him; ordinarily, however, he delegates many specific
Superfund authorities and responsibilities to the program offices of EPA.
Generally, the Administrator delegates authority to senior management officials
that report directly to the Administrator.
The Administrator assigns most responsibilities for carrying out specific
CERCLA provisions to EPA Regional Administrators and to the Assistant
Administrator for the Office of Solid Waste and Emergency Response (OSWER). A
wide variety of other EPA offices also play roles in CERCLA implementation.
These other offices include the Office of Enforcement and Compliance Monitoring
(OECM), the Office of Research and Development (ORD), and the Office of Solid
Waste (OSW). Each internal delegation indicates whether or not the authority
for executing a Superfund provision may be redelegated. If authority is
redelegated, the original delegatee remains accountable to the Administrator for
exercising the authority.
Two program offices work within OSWER to administer the major activities
of CERCLA. OWPE executes the enforcement-related activities of Superfund through
its CERCLA Enforcement Division. OERR is responsible for administering the
Superfund response program.
EPA Interagency Agreements and Memoranda of Understanding with Other Federal Agencies
In coordinating CERCLA's implementation, EPA occasionally exchanges goods
and services with other Federal agencies and with State governments. Such
exchanges are governed by interagency agreements (LAGs).* The IAG is a written
agreement designed to carry out a distinct project whose objective is clearly
defined. All activities under an IAG must serve the objective through the term
of the project. EPA undertook an initiative to promote consistent use of lAGs
and to improve accounting and cost documentation practices. A draft manual
entitled Regional Processing of Superfund lAGs was distributed in July 1987.
EPA lAGs may be divided into two major classes. The first class is
characterized by an exchange of goods or services for monetary reimbursement,
or a sharing of goods and services between two parties. The second class is
characterized by a policy agreement or Memorandum of Understanding (MOU). The
MOU sets forth the policies and procedures governing the relationship of two
parties, or it governs the provision of services without monetary reimbursement.
No funds are exchanged under an MOU.
*Agreements between EPA and States governed by a Superfund Memorandum of
Agreement focus on environmental problems, objectives, and points of
coordination. Such agreements are not considered lAGs.

FISCAL 1987 REMOVAL ACTIONS
Removal actions vary greatly in length and are undertaken on a continuous
basis throughout the year. Consequently, the table shows many FY87 starts that
will be completed in future fiscal years. In addition, some completions noted
are for starts in prior fiscal years. Start dates signify the first day that
the ERCs contractor is onsite. The completion date marks the day that all waste
is at its ultimate disposal location. See section 2.2 of this Report for a
summary of removal actions by State and Region.

Progress Toward Implementing Superfund: Fiscal Year 1987
APPENDIX C
DETAILED ROD DESCRIPTIONS
This appendix provides detailed descriptions of FY87 feasibility studies
(FSs) as required by CERCLA section 301(h)(1)(A). These descriptions are based
on Records of Decision (RODs) signed after 11/17/86, when the section 121 cleanup
standards added by SARA became fully effective. Although a total of 75 RODs were
signed in FY87, four of these were signed before 11/17/86; 70 RODs are summarized
in this appendix (rather than 71) because a single ROD was signed for two
actions: the Environ-Chem and Northside Landfill sites in Indiana.
Each summary provides background information on the Superfund site,
including the type of operation, contaminants of concern, past investigations,
description of operable units, and the enforcement status. The section on site
work provides the date of the remedial investigation (RI) initiation and key
findings of the RI. The third section describes the FS, including the
alternative remedial actions considered, the major Federal or State applicable
or relevant and appropriate requirements (ARARs) identified for the site, and
a summary of community involvement. In the last section, the selected remedial
alternative is described. This section also provides information on the use of
alternative or resource recovery treatment technologies and how well the selected
remedy meets the requirements of CERCLA.
All sites summarized in the appendix are listed below by EPA Region. The
National Priorities List (NPL) number given is the site ranking as of July 30,
1987. Proposed NPL sites are placed in groups (Gr) corresponding to groups of
50 on the final NPL. Federal facility sites are placed in similar groupings and
designated by the letter "F" following the group number. The entity leading the
project is also listed, i.e., Federal lead by the EPA remedial program and Fund-
financed (F); EPA enforcement program lead (ENF); potentially responsible party
lead (PRP).

Progress Toward Implementing Super-fund: Fiscal Year 1987
DAVIS LIQUID SITE
SMITHFIELD, RHODE ISLAND
HRS Score: 4725 NPL Rank: 216
Background
The Davis Liquid site covers 15 acres and is located in a rural section of
the town of Smithfield in Providence County, Rhode Island. Although the site
is bounded by forest and wetlands, the area is under increasing Low-density
residential use; there are 100 homes within one mile of the site. Areas of
natural resource importance in the vicinity of the site include surrounding
wetlands, the aquifers underlying the site damage area, and the Stillwater
Reservoir. The wetlands provide habitat for many plant and animal species and
the aquifers are tapped by local residents as their sole source of water supply.
Stillwater Reservoir is a Class B water body and a potential water supply for
the Town of Smithfield.
The site served as a disposal location for a variety of liquid and solid
wastes throughout the 1970s. Drummed wastes and bulk liquid wastes from tank
trucks were dumped into the unlined pits and lagoons at the site. In L978, after
a tire fire at the site and subsequent investigation, approximately six to eight
residents brought their concerns to the Smithfield Town Council. A court order
in 1978 prohibited the disposal of hazardous waste at the site. At that time,
State efforts to gain access to the site were met with a series of legal
challenges by Mr. Davis, the site owner, which resulted in delays in addressing
the contaminants on site. A group of citizens lobbied the Town Council for
closure of the site and initiated legal and investigative action against the site
owner.
In 1980, the Rhode Island Department of Environmental Management (RIDEM)
conducted a full-scale ground-water contamination study of monitoring wells on
the Davis property and surrounding residential properties. Contaminants were
found in both the ground-water wells on and off site and the surface water
adjacent to the Davis site. A finding of contaminants at concentrations above
EPA health and safety criteria prompted RIDEM to supply bottled water to
residents using the affected wells.
EPA and the State of Rhode Island signed a cooperative agreement to initiate
a State lead remedial investigation/feasibility study (RI/FS). The site was
placed on the NPL in September 1983. The RI was completed by EPA in November
1986, following initial work by RIDEM. The FS was released for public comment
in July 1987. The ROD was signed September 29, 1987. Approximately 26
potentially responsible parties (PRPs) were issued General Notice Letters
encouraging them to perform the response activities necessary to cleanup the
site. Negotiations with the PRPs are currently ongoing.
164
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Site Work
In 1985, the U.S. Government brought action against the members of the Davis
family to ensure access for EPA to complete the RI/FS. During the winter of
1985, EPA removed approximately 600 drums containing hazardous wastes. The
wastes disposed of at the site include neutralized wastes from incinerated toxic
materials, drums containing chemical and sewage sludges, waxes and liquids, and
liquids that included organic solvents.
Data from the RI indicate that significant quantities of hazardous
substances remain on site following the removal actions. Contamination was found
in the soil, ground water, surface water, and sediments on site, in the
overburden and bedrock aquifer, and in the ground water and surface water off
site. Volatile organic contaminants such as trichloroethylene (TCE) toluene and
xylene were found in high concentrations. Inorganic contaminants included lead
and nickel at concentrations in excess of Federal aquatic toxicity criteria for
chronic effects. The filling of wetlands with debris (e.g. tires) has increased
water levels at the site, threatening the wetlands vegetation.
Description of Feasibility Study
The objective of the FS was to develop alternatives for controlling the
source of contamination and preventing further migration of the contaminants.
Alternatives were evaluated with regard to CERCLA criteria. The alternatives
comprised two types of remedies: source control (soil) and management of
migration (ground water, surface water, and sediments). The following
alternatives were considered:
(1) No action alternative;
(2) Source control alternatives --
• on-site low-temperature thermal soil treatment,"
• on-site thermal destruction; and
• off-site thermal destruction.
(3) Management of migration alternatives --
• on-site treatment of the ground water and construction of an
alternate water supply;
• combined treatment of contaminated surface water in the ground-
water treatment system; and
• off-site sediment dredging and treatment.
In general, those commenters that submitted formal written and/or oral
comments supported EPA's preferred alternative (see below). Community interest
was high concerning the investigation of contaminated residential wells and
public meetings were held on the results of the RI and the FS. Since the
165
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
completion of the draft FS, most commenters had major concerns regarding the
safety of air emissions from the incineration process.
Description of Selected Remedy
The selected remedial action is a comprehensive approach for site
remediation. The source control component includes excavation of waste and
soils, treatment by thermal destruction, and disposal in an on-site Resource
Conservation and Recovery Act (RCRA) Subtitle C landfill. Surface-water runoff
and ground-water recharge to the stream on site will be isolated for collection
and treatment. Wetlands disturbed by the remedial action will be restored. The
management of migration component includes the design and construction of an
alternate water supply, and the design and construction of a ground-water
extraction, treatment, and flushing system.
Major applicable or relevant and appropriate requirements (ARARs) considered
included RCRA closure performance standards and ground-water protection
requirements, the Clean Water Act (CWA), Safe Drinking Water Act (SDWA),
Executive Order 11990 for Protection of Wetlands, Toxic Substances and Control
Act (TSCA), and the Clean Air Act (CAA). Also, the remedy must be consistent
with EPA Ground-water Protection Strategy, as the aquifer at the site is Class
II and requires restoration. State ARARs include the RIDEM ground-water
protection rules and regulations, and the Rhode Island Wetland Protection Act.
The selected remedy is expected to meet ARARs, complies with CERCLA's
statutory preference for a remedy that significantly reduces the volume,
toxicity, or mobility of hazardous substances, uses alternative treatment
technologies, is cost-effective, and represents a permanent solution.

OTTATI AND GOSS/
GREAT LAKES CONTAINER CORPORATION SITE
KINGSTON, NEW HAMPSHIRE
HRS Score: 53.41 NPL Rank: 130
Background
The Ottati and Goss/Great Lakes Container Corporation (O&G/GLCC) site is
located on approximately 35 acres in Kingston, New Hampshire. The O&G/GLCC
comprises seven non-contiguous acres on the site. Since the late 1950s, the
site has been used by several companies for the reconditioning of disposal drums
and for the disposal of hazardous waste. Caustic rinse solutions from the
reconditioning operations were released onto the site, and heavy sludges were
brought to the site for processing, beginning in 1978. Volatile organic
compounds (VOCs), acid and base/neutral (ABN) compounds, PCBs, and metals have
contaminated ground water, surface water, and soils on the site. Some of the
contaminants present, such as benzene, arsenic, and TCE, are known or suspected
carcinogens. Individual residential wells derive ground water from aquifers in
the area, although no residential well contamination has been attributed to the
site.
On July 1, 1979, the New Hampshire Bureau of Solid Waste Management ordered
the operators of the site to remove waste drums and to cease processing
operations. A subsequent response action involved excavation and removal of
12,800 tons of drums and contaminated soils. The O&G/GLCC site was placed on
the NPL in September 1981. The remedial investigation (RI) initiated in 1983
indicated contamination of soil, surface water, ground water, and sediments.
In an effort to compel private parties to respond to the contamination, EPA filed
a complaint in May 1980. The court concluded in 1985 that a number of parties
are liable for the hazardous substances present at the site. The outcome of
settlement proceedings, and the determination of responsibility for remediation,
were not known at the time the ROD was signed on January 16, 1987.
Description of Site Work
The State lead RI/FS for the site was completed in August 1986. The RI
indicated high concentrations of VOCs, PCBs, ABNs, metals, and cyanide in soils
at numerous locations on the site. VOCs and metals are the principal
contaminants in the ground water, and evidence suggests these compounds may be
migrating off site. EPA believes that the soil contamination presents a direct
contact risk, along with risks from ingestion of contaminated ground water.
Description of Feasibility Study
The feasibility study (FS) was conducted in 1986 to evaluate remedies for
the O&G/GLCC site. EPA eliminated 12 of the initial 18 remedial alternatives
during an initial screening phase. The remaining six alternatives were evaluated
on the basis of engineering practice, protection of public health (including
extent of compliance with ARARs), the use of alternative technologies, and cost.
These six alternatives were as follows:
167
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
(1) No action, with site monitoring and restricted land
use;
(2) Ground-water interception trench, on-site disposal of
wastes, Resource Conservation and Recovery Act (RCRA)
site cap, and source control;
(3) Alternative 2 plus ground-water extraction and
treatment;
(4) Alternative 3 plus alternate water supply;
(5) Removal of contaminated soils and sediments to a RCRA
facility; and
(6) Treatment of soils and sediments, ground-water
treatment, and site cover.
Evaluation of the alternatives included consideration of their compliance
with potential applicable or relevant and appropriate requirements (ARARs). The
use of a RCRA cap would require compliance with RCRA standards, and the
remaining waste on site would make RCRA closure and post-closure requirements
relevant and appropriate. The Toxic Substances Control Act (TSCA) disposal
standards for PCBs would also apply, as would requirements governing the removal
of sediments from wetlands. The removal of wastes off site would be subject to
RCRA and TSCA transportation and disposal regulations. The treatment of ground
water, or destruction of contaminated soil by incineration, would also have to
conform to Federal standards.
EPA held two public comment periods between September and December 1986 for
interested parties to comment on the draft FS and the preferred alternative (see
below). A third comment period, allowing for public response to a ground-water
model of the site, began in late December 1986. Local citizens and local and
State officials were actively involved with site activities. New Hampshire
environmental authorities have collaborated with EPA personnel since 1981 in
collecting and analyzing data.
Description of Selected Remedy
The preferred alternative, combining elements of several remedial options,
includes excavation and incineration of selected PCB-contaminated soils,
aeration of 14,000 cubic yards of soil to remove VOCs, and ground-water
extraction, treatment, and monitoring. EPA believed that both source control
and ground-water remediation were necessary to protect public health and the
environment. The source control alternative is necessary to minimize the
migration of contaminants into ground water and the risk associated with direct
contact to the soils. This phase of the remedy uses incineration and aeration
of VOCs, the latter of which is considered an innovative technology. EPA
believes that treatment of the hazardous substances will be effective and
reliable over the long term in minimizing risk. EPA's decision is consistent
with the statutory mandate of CERCLA to select permanent solutions and
alternative treatment technologies to the maximum extent practicable.

RESOLVE, INC., SITE
SECOND OPERABLE UNIT
NORTH DARTMOUTH, MASSACHUSETTS
HRS Score: 47.71 NPL Rank: 206
Background
The Resolve, Inc., site is located in North Dartmouth, Massachusetts, about
8 miles west of Fall River. The 6-acre site was used as a waste chemical
reclamation facility from 1956 to 1980. The land surrounding the site primarily
is zoned for residential use, and all of the nearby residences obtain their
drinking water from private wells. The nearby Copicut River drains into Cornell
Pond, a popular sport-fishing area.
During its operation as a chemical reclamation facility, the site received
solvents, waste oils, organic liquids and solids, inorganic liquids and solids,
and PCBs. Resolve disposed of the hazardous byproducts from its reclamation
processes either in one of four unlined lagoons located on the site, or by
landfarming, a method by which wastes are spread into the soils of the site.
In 1974, the Massachusetts Division of Water Pollution Control granted Resolve
a license to collect hazardous waste from 1974 to 1980. However, in December
1980 Resolve surrendered its license after the Department discovered violations
of the license provisions. Investigations conducted by the Department at that
time showed no migration of contaminants from the four lagoons. Resolve removed
drums, buildings, and loading and unloading pads in 1981, but did not empty the
contents of the lagoons. When leaching of wastes was discovered in 1982, EPA
placed the site on the NPL.
EPA initially divided remedial activities at the site into two operable
units. EPA initiated a remedial investigation (RI) for the first operable unit
in the fall of 1982 to assess the extent of on-site source contamination.
Following the completion of this RI in June 1983, EPA undertook a feasibility
study (FS) that recommended source material be excavated and the site be
encapsulated. A ROD for the on-site operable unit was signed on July 1, 1983.
From September 1985 to February 1986, EPA conducted the RI/FS for the second
operable unit to assess off-site contamination. In April 1985, before the ROD
for the off-site operable unit was signed, EPA became aware that on-site PCB
contamination was more extensive than originally believed, and that PCBs were
migrating off site. In September 1985, EPA initiated a comprehensive on- and
off-site RI/FS to determine the extent of the PCB contamination. EPA completed
this comprehensive RI/FS in February 1987 and the ROD was signed in September
1987.
Description of Site Work
The results of the final, comprehensive RI indicated that PCBs were
present in on-site soils in significant concentrations despite the earlier
removal action, and that, as a result of their having dissolved in solvents that
were also located in the soil, PCBs were migrating through ground water toward
the Copicut River. EPA also identified other hazardous constituents of concern,
including methylene chloride, 2-butanone, and toluene. The four major sources
of contamination at the site were located primarily around the lagoons. The RI
169
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
concluded that these sources had contaminated on-and off-site ground water and
off-site surface water, in addition to the soil.
Description of Feasibility Study
The comprehensive FS identified remedial actions that would result in
source control and stop the migration of contaminants. Seven remedial options
remained after a preliminary screening:
(1) No action;
(2) On-site thermal destruction of 64,000 cubic yards of
contaminated soils;
(3) On-site dechlorination of 64,000 cubic yards of contaminated
soils;
(4) Encapsulation of the site, in situ flushing of contaminated
soils, and treatment of source materials having the highest
concentrations of PCB contamination;
(5) Off-site thermal destruction of contaminated soils;
(6) On-site treatment of ground water; and
(7) Heated influent air stripping of ground water.
The FS also identified applicable or relevant and appropriate requirements
(ARARs) for each of the remedial alternatives. These ARARs included Resource
Conservation and Recovery Act (RCRA) disposal and closure requirements, Toxic
Substances and Control Act (TSCA) PCB cleanup standards, Safe Drinking Water Act
(SDWA) Maximum Contaminant Levels (MCLs), and Department of Transportation (DOT)
regulations for the transportation of hazardous wastes.
Citizen involvement in the RI/FS and selection of remedy processes was
substantial. EPA held several public meetings to explain the remedies, and
actively encouraged the development of a Citizen's Advisory Committee. Several
commenters commended EPA for selecting an innovative technology to remediate the
Resolve site (see next section for description). The State of Massachusetts
al-so was consulted and concurred with the remedy selected.
Description of Selected Remedy
The remedy selected (Alternative 3) addressed both source control and
prevention of the migration of contaminants. Specifically, the remedy included:
• Excavation of 22,500 cubic yards of PCB-contaminated soils,
treatment in a mobile dechlorination unit to achieve a level
of cleanliness corresponding to 25 parts per million (ppm)
PCBs, and replacement of the treated soil on site;
170
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
• Excavation of 3,000 cubic yards of PCS-contaminated
sediments in wetland resource areas and treatment in a
dechlorination unit to achieve 1 ppm PCB;
• Restoration of ground water using on-site air stripping and
carbon absorption; and
• Placement of institutional controls on ground water that
cannot be adequately cleaned to achieve a drinking water
standard.
This remedy uses an innovative technology (i.e., dechlorination) and is
expected to satisfy the CERCLA mandate for protecting human health and the
environment, attaining all ARARs, and permanently reducing the toxicity,
mobility, or volume of hazardous substances.

BROWNING-FERRIS INDUSTRIES (BFI) SOUTH BRUNSWICK
LANDFILL SITE
SOUTH BRUNSWICK, NEW JERSEY
HRS Score: 53.42 NPL Rank: 125
Background
The Browning-Ferris Industries (BFI) Landfill Site is located approximately
1/2 mile northwest of Route 1 in South Brunswick, New Jersey. The landfill
occupies approximately 68 acres and is surrounded primarily by wooded land,
although residences and a school are located nearby. The site also is close to
Heathcote Brook, a tributary of the Millstone River, which occasionally serves
as a source of drinking water for the City of New Brunswick at a point 10 miles
downstream.
The BFI site was a solid waste landfill for approximately 20 years before
it was closed in 1978. It received municipal, hazardous, and chemical wastes
and pesticides during the time it was open. BFI acquired the site from G.J.
Spilatore Excavation Company in May 1973; both parties were identified as
potentially responsible parties (PRPs), although BFI took full responsibility
for the remediation process.
EPA conducted an investigation of the site in June 1980. In 1982, EPA and
BFI entered into a three-stage Consent Order agreement to remediate the site.
Phase I of the plan called for BFI to conduct a remedial investigation (RI) of
the site, which was completed during 1982. The site was listed on the NPL in
December 1982. Phase II of the agreement required BFI to develop a remedial
plan and construct an EPA-selected remedy; BFI completed this phase between May
1983 and September 1985. Phase III required BFI to conduct a post-remedial
environmental monitoring program, which BFI proposed in June 1987. Because of
the Consent Order, no feasibility study (FS) was ever conducted for the site.
When BFI proposed Phase III of its program, EPA developed the ROD to determine
whether the remedial action selected in 1983, before the SARA amendments to
CERCLA, was consistent with the new statutory requirements.
Description of Site Work
The RI conducted by BFI indicated that a shallow aquifer beneath the site
was contaminated with total volatile organics (TVOs). Because some of the
bedrock underlying this upper aquifer was fractured, a deeper aquifer also had
become contaminated with TVOs. The RI also discovered that leachate was seeping
from one side of the landfill and migrating toward Heathcote Brook.
Description of Feasibility Study
Because the PRP had developed the remedial actions, EPA did riot develop a
formal FS. Instead, the ROD included EPA's analysis of alternative remedial
actions, in which EPA screened available technologies and identified the
following nine options to be evaluated against the criteria of CERCLA:
(1) No action;
172
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
(2) Leachate collection system;
(3) Leachate collection system and clay cap;
(4) Slurry wall constructed to the depth of bedrock beneath the
site;
(5) Slurry wall constructed to the depth of bedrock and clay cap;
(6) Slurry wall constructed to the depth of residual soil;
(7) Slurry wall constructed to the depth of residual soil and
clay cap;
(8) Slurry wall constructed both to residual soil and to bedrock
and a clay cap; and
(9) Slurry wall constructed both to residual soil and to
bedrock, a clay cap, and a leachate collection system.
The analysis also identified applicable or relevant and appropriate
requirements (ARARs) that remedial actions must meet. ARARs identified for this
site included Resource Conservation and Recovery Act (RCRA) regulations for
closure of hazardous waste landfills, the Clean Water Act (CWA) pretreatment
standards for discharge to publicly owned treatment works (POTWs), and Executive
Order 11990 for the Protection of Wetlands. A New Jersey State Administrative
Code requirement for capping of landfills also was identified as an ARAR for
the site.
The New Jersey Department of Environmental Protection (NJDEP) agreed that
on-site containment of the contamination and monitoring of the site are
protective of human health and the environment, and concurred with the remedy
selected. Concerned citizens were informed of the remedial action and
monitoring requirements of the BFI plan, and EPA held a public meeting on August
6, 1987, to explain the long-term monitoring plan and discuss the success of the
constructed remedy. Overall, the public and local officials have expressed
satisfaction with the selected remedy and the timeframe in which it was
implemented.
Description of Selected Remedy
The remedy selected for the site in 1985 by BFI was Alternative 9,
construction of a slurry wall to the depth of bedrock beneath the portions of
the site where it is relatively shallow and to the depth of residual soil for
the remainder of the site. The remedy also included placement of a clay cap
over the site and the construction of a leachate collection system. Leachate
collected at the site was treated at a nearby wastewater treatment plant. The
treatment was selected on the basis of its implementability and proven
effectiveness. Treatment of the hazardous waste buried at the site was not
feasible because discrete areas of hazardous waste disposal could not be
identified, and excavation and treatment of the entire 68 acres was determined
not to be feasible. The selected remedy complies with the preference for
173
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
treatments that reduce the toxicity, mobility, or volume of hazardous
constituents because the leachate collection and wastewater treatment processes
are reducing the amount of hazardous constituents at the site.
The evaluation of the remedial alternatives in the ROD concluded that this
remedy best meets the requirements of CERCLA. The remedy was judged to be cost-
effective and protective of human health and the environment. The remedy also
meets Federal ARARs for capping and the pretreatment standards for discharge to
POTWs. The remedy does not meet the requirements of the New Jersey
Administrative Code for capping, but EPA waived this State ARAR because the
selected remedy is achieving a standard of performance equivalent to that
required by the State regulation.

CHEMICAL CONTROL CORPORATION SITE
ELIZABETH, NEW JERSEY
MRS Score: 47.13 NPL Rank: 223
Background
The Chemical Control Corporation (CCC) site is located in Elizabeth, New
Jersey, on a peninsula formed by the Elizabeth River and the Arthur Kill.
Despite a ban by the State of New Jersey since 1980, recreational fishing
continues within 3/4 of a mile from the site, and both water bodies are used for
commercial purposes.
Chemical Control Corporation operated between 1970 and 1978 and was
involved in the business of hauling, treating and disposing of industrial
wastes. Throughout its operations, CCC was cited for violations such as
illegally discharging liquids and accumulating drums that contained incompatible
wastes. In 1978, the Corporation was placed into operational receivership by
the Superior Court of New Jersey. The State of New Jersey began a cleanup of
the site in March 1979. The cleanup included removing solids, liquids, nearly
10,000 drums of waste, 10 pounds of infectious wastes, 7 pounds of radioactive
wastes, and 24 gallons of explosive liquids. In April 1980, an explosion and
fire occurred at the site that were not brought under control for more than 10
hours. After the fire, New Jersey continued its cleanup of the site by removing
buildings, drums, tanks, and surface soil. The State also operated a ground-
water recovery and treatment system at the site from November 1980 to July 1981.
In 1981, the site was ranked for inclusion on the Superfund Interim
Priorities List. EPA has conducted two Initial Remedial Measures (IRMs) that
included decontaminating and removing trailers from the site, cleaning a
contaminated sewer line, and recovering containers from the Elizabeth River.
A final IRM has been proposed to remove deteriorating gas cylinders from the
site. Drums of waste currently remain on the site, which is surrounded by a
security fence.
The EPA lead remedial investigation (RI) was completed in July 1986, and
the results of the feasibility study (FS) were released in June 1987. Notice
letters were sent in August 1987 to 31 parties identified as generators of the
wastes or potentially responsible parties (PRPs). Informal discussions with
the PRPs to reach a possible settlement continue. The ROD was signed on
September 23, 1987.
Description of Site Work
Following the first two IRMs, EPA initiated an RI to determine the extent
of soil, ground-water, and river contamination on the site, as well as the human
health risks associated with that contamination.
The RI indicated that soil and river sediments are contaminated with
organic compounds and, to a lesser degree, with metals. The RI also found low
concentrations of contaminants in the ground water.
175
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
The EPA lead feasibility study (FS) was completed in June 1987. The
objectives for the remedial action, developed in the FS, were based on the
findings of the RI. The RI identified the presence of highly contaminated soil
as posing the greatest potential risk to the public health and the environment.
The objective of the remedial action, therefore, was to reduce the mobility and
toxicity of the contaminants in the soil, protect against human exposure to the
contaminated soil, assure that leaching of contaminants from the soil will not
increase, and return the site to a condition consistent with future industrial
development in the area. The following eight remedial alternatives were
considered:
(1) No action;
(2) Containment using a ground-water barrier;
(3) In situ soil washing with a ground-water barrier;
(4) In situ soil fixation;
(5) Excavation and off-site disposal to a landfill;
(6) Excavation, on-site treatment, and off-site disposal;
(7) Excavation, on-site treatment, and on-site disposal; arid
(8) Excavation, off-site incineration, and disposal.
Evaluation of the alternatives considered applicable or relevant and
appropriate requirements (ARARs), and also considered the utilization of
permanent solutions and alternative treatment technologies. Federal and State
ARARs identified included Executive Order 11988 for Management of Floodplains
and discharge limits for surface-water protection. Another ARAR was the
Endangered Species Act because the surface water near the site is within
breeding range of the endangered short-nosed sturgeon. New Jersey has indicated
that State ARARs will be satisfied if a bioassay is performed, and if
contaminants in the soil are found not to exceed State guidelines. Resource
Conservation and Recovery Act (RCRA) regulations were not considered applicable
because the site did not operate under a permit issued pursuant to that act.
However, the selected remedy was evaluated for compliance'with RCRA, as relevant
and appropriate, by considering the hypothetical situation of a site similar to
Chemical Control that was operated under a permit.
Input received during the public comment period was considered in the
decision. Community concern began in 1977 when citizens and local officials
complained about the site. The main concern of local officials is that a
thorough, permanent remedy be implemented expeditiously.
176
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Selected Remedy
The selected remedy is the in situ soil fixation alternative (Alternative
4) that includes repairing berms on the site, removing debris, sealing the sewer
line, and monitoring to evaluate the effectiveness of the remedy. In situ
fixation of the soil meets CERCLA requirements to reduce the mobility of
toxicants, provide a permanent and long-term solution, and use an alternative
treatment technology that offers a cost-effective remedy. The on-site operation
may temporarily violate Executive Order 11988 for the Management of Floodplains
while equipment is located on the site. Both the Department of Commerce and the
Agency for Toxic Substances and Disease Registry concurred that the selected
remedy offers adequate protection of public health.

COOPER ROAD DUMP SITE
VOORHEES TOWNSHIP, NEW JERSEY
HRS Score: 36.79 NPL Rank: 473
Background
The Cooper Road Dump site is located in Voorhees Township in the north
central part of Caraden County, New Jersey. The dump encompasses a surface area
of less than 100 square feet. The area around the site is being developed for
residential use, with the closest house within 300 feet of the site. Aquifers
supplying drinking water underlie the site and there are several potential
surface-water discharge points from the aquifer in the vicinity.
Contamination was discovered in mid-1982 when several dozen broken and
sealed small glass vials containing liquid chemicals were found partially buried
in a soil pit area. An analysis of the vials by the New Jersey Department of
Environmental Protection (NJDEP) indicated the presence of hazardous substances,
including benzene, xylene, and naphthalene. The NJDEP subsequently ordered the
owner of the property to remove the hazardous materials but no reply was
received.
A surface cleanup was completed in May 1984 by a new site owner, the
Cinamerican Company, during which all the vials and soils to a depth of 6 inches
below any vials were removed. Although no further soil contamination was
revealed, the site was placed on the final NPL in November 1984 for
determination by EPA as to whether there had been a release of contaminants into
the underlying soils or ground water. In September 1986, EPA arid the NJDEP
agreed to conduct sampling at the site, and the sampling reports were completed
in August and September 1987. The ROD was signed September 30, 1987.
No additional enforcement actions are anticipated because the generators
of the vials have not been located, the vials appear to have been dumped without
the knowledge of the previous or current property owners, and the current
property owner completed a surface cleanup to the satisfaction of EPA.
Description of Site Work
Results of the soil and ground-water sampling in April 1987 revealed
certain contaminants at concentrations above background levels. However,
because contamination was found at the laboratory where the samples were
analyzed, the validity of the sampling studies was called into question.
Further EPA testing revealed no contaminants in concentrations that would
produce any adverse health effects, based on Federal and State guidelines and
criteria. The risk assessment in the remedial investigation (RI) determined
that there was no potential exposure to contamination.
178
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
Because the field investigations indicated no contamination, no potentially
feasible remedial actions were evaluated. It was also determined that no
monitoring of the shallow underlying aquifer was necessary.
Applicable or relevant and appropriate requirements (ARARs) identified for
the ground water at the site were EPA's Maximum Contaminant Levels (MCLS) under
the Safe Drinking Water Act (SDWA), and NJDEP'S Interim Action Levels for
Selected Organics in Drinking Water. Action levels for certain metals in soil
have been developed by NJDEP and were used as ARARs. No contaminants exceeded
ARARs.
Community involvement was solicited at the conclusion of the RI and a
public meeting was held in September 1987. Town officials and citizens who live
in the vicinity of the site attended the meeting. Since the discovery of the
site in 1982, community concern has focused on potential health effects of
community exposure, potential adverse effects on housing values, and the timing
of the removal of the site from the NPL.
Description of Selected Remedy
The remedy selected for the site calls for no further action. The remedy
is considered to comply with ARARs, to be cost-effective, and to be protective
of human health and the environment.

DIAMOND ALKALI SITE
(ALSO KNOWN AS DIAMOND SHAMROCK SITE)
SOURCE CONTROL OPERABLE UNIT
NEWARK, NEW JERSEY
HRS Score: 35.40 NPL Rank: 523
Background
The Diamond Alkali Site (also known as the Diamond Shamrock Site) is
located in Newark, New Jersey, along the Passaic River. The 3.4-acre site has
been used for industrial purposes since the 1870s. From 1951 to 1969, the
Diamond Alkali Company (subsequently known as the Diamond Shamrock Chemicals
Company) manufactured DDT and other chemicals on the site, including sodium
trichlorophenol (TCP). After 1969, the site was owned or leased by several
companies.
During 1983, as a result of EPA's strategy to inspect all sites known to
have produced TCP, the site was sampled for dioxin contamination. The tests
showed that dioxin contamination was present, and in March 1984, the New Jersey
Department of Environmental Protection (NJDEP) issued an Administrative Order
to Diamond Shamrock to conduct a remedial investigation/feasibility study
(RI/FS). The site was listed on the NPL in September 1984 and Diamond Shamrock
completed the RI/FS in December 1985.
EPA and NJDEP divided the site into operable units based on the results of
the RI conducted by Diamond Shamrock. The first operable unit addressed source
control and remediation of ground water. EPA made public a proposed remedial
action plan in July 1987. After responding to public comments, the ROD for the
first operable unit was signed in September 1987. Subsequent operable units may
address remediation of ground-water contamination, and the remediation of the
sediments of Passaic River.
Description of Site Work
Diamond Shamrock completed the RI in May 1985 under the supervision of the
NJDEP. The RI included sampling of air, ground water, soil, surface water,
buildings on the site, storage drums, arid off-site properties. The RI indicated
that the site was contaminated by a large number of hazardous substances, and
that the greatest risks were posed by DDT and dioxin. The pathways of exposure
determined to cause risk included: migration of hazardous substances to surface
water and sediments of the Passaic River; migration of airborne hazardous
substances from volatilization and dust generation; and migration of hazardous
substances into the ground water.
Description of Feasibility Study
The FS for the first operable unit evaluated remedial alternatives for
source control, including the prevention of further releases of hazardous
substances to the Passaic River. Seven remedial alternatives were developed:
(1) No action;
180
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
(2) On-site containment of wastes with a cap and slurry wall;
(3) On-site containment of wastes with a cap and slurry wall and
ground-water treatment;
(4) Excavation of wastes and on-site thermal destruction,
containment of remaining wastes with a cap and slurry wall,
and on-site ground-water treatment;
(5) Excavation of wastes and construction of an on-site vault
encapsulating all wastes and on-site ground-water treatment;
(6) Excavation of wastes and off-site disposal, containment of
remaining wastes with a cap and slurry wall, on-site ground-
water treatment, and decontamination of buildings; and
(7) Excavation of wastes and off-site thermal treatment,
containment of remaining wastes with a cap and slurry wall,
on-site ground-water treatment, and decontamination of
buildings.
Description of Selected Remedy
The remedy selected was similar to Alternative 3 of the FS, on-site
containment of wastes with a cap and slurry wall and on-site ground-water
treatment. The remedy was expanded to include protection against floods with
the construction of a flood wall, off-site removal of certain drums located on
the site, and requirement for a follow-up FS every 2 years.
The remedy is expected to attain all ARARs except the three that were
waived in accordance with CERCLA section 121(d)(4)(B), that allows a waiver from
meeting an ARAR when attaining the ARAR will result in a greater risk to human
health or the environment. ARARs not met for this reason were RCRA land
disposal restrictions and landfill design requirements, and State landfill
design requirements.
The remedy is expected to be protective of human health and the environment
consistent with the requirements of CERCLA. The State of New Jersey was
consulted and concurred with the selected remedy.

MONTGOMERY TOWNSHIP HOUSING DEVELOPMENT SITE
ALTERNATE WATER SUPPLY OPERABLE UNIT
MONTGOMERY TOWNSHIP, NEW JERSEY
HRS Score: 37.93 NPL Rank: 438
Background
The Montgomery Township Housing Development (MTHD) site is a 72-acre tract
of land located in Montgomery Township, New Jersey, 15 miles northeast of
Trenton. There are 77 homes located on the site. Each home has its own
drinking water well that draws water from the Brunswick Formation aquifer that
underlies the site. Ground water in the Brunswick formation is also used for
industrial purposes.
In 1978, a Rutgers University study of the Rocky Hill Boroug,h well, which
is located nearby but not within the MTHD, revealed that the well was
contaminated with trichloroethene (TCE). In 1979, after continued testing of
this water supply indicated greater TCE concentrations, the New Jersey
Department of Environmental Protection (NJDEP) began sampling commercial and
domestic wells in Montgomery Township. Included in the NJDEP sampling program
were private wells, industrial supply wells, soils, surface waters, and septic
tanks. In August 1980, Montgomery Township authorized the installation of
Elizabethtown Water Company (EWC) water mains in the MTHD, and residents were
advised not to use well water. As of September 1987, 38 residential wells had
been connected to water mains.
In 1984, NJDEP entered into a cooperative agreement with EPA under which
NJDEP would perform the remedial investigation/feasibility study (RI/FS) for the
MTHD and Rocky Hill Municipal Well (RHMW) sites. Because of the proximity of
the sites, and the similarity of the contaminants found, NJDEP performed the
RI/FS for the two sites under one cooperative agreement. Due to the potential
health risks posed by the possible consumption of contaminated ground water, EPA
designated as an operable unit the provision of an alternate water supply for
the 120 residents of the MTHD with private drinking water wells. The State lead
RI/FS for this operable unit was completed in July 1987, and the ROD was signed
in September 1987. Remediation of the aquifer will be addressed in a subsequent
operable unit ROD.
The NJDEP has not: been able to identify the precise source of the TCE
contamination, although several industrial and commercial establishments within
the site area, including an industrial research facility, are believed to be
potential sources. There is no conclusive evidence, however, connecting these
PRPs to the TCE contamination.
Description of Site Work
The NJDEP separated the joint-site RI/FS into two phases. Phase 1, the
geohydrologic investigation, was completed in January 1987. The objective of
this phase was to characterize and determine the boundaries of the ground-water
contaminant plume. Results indicated the ground water was contaminated with
TCE, at levels up to 650 ppb, and with other volatile organic compounds. The
182
-------
Progress Toward Implementing Super-fund: Fiscal Year 1987
TCE-contaminated ground-water plume, which appears to have been in a steady
condition for at least the past 8 years, threatens an area of approximately
25,000 square feet. The RI, however, could not precisely determine the extent
of the plume.
The second phase of the RI is continuing and is attempting to better define
the contaminant plume. Remediation of the aquif e"r will be evaluated in a
subsequent FS.
Description of Feasibility Study
The State lead FS for the alternative water supply operable unit addressed
the health risks to the 120 MTHD residents who continue to utilize contaminated
or threatened private wells. The following remedial alternatives were
developed:
(1) No action, except for ground-water monitoring;
(2) Temporary provision of bottled water to residents (for
2 to 12 years);
(3) Extension of the EWC Distribution System to allow for
service connections to all threatened residents, and
closure of individual residential wells; and
(4) Construction of a new centralized community well and
treatment of well water.
New Jersey Maximum Contaminant Levels (MCLs) and Safe Drinking Water Act
(SDWA) MCLs were determined to be applicable or relevant and appropriate
requirements (ARARs) at this site. Drinking Water Health Advisories and
reference levels for carcinogens are not enforceable requirements, but were
considered in the analysis of remedial alternatives.
MTHD residents showed concern about the site, particularly about the
quality of EWC water. However, EPA and NJDEP have confirmed that this water
supply consistently is in compliance with State and Federal water quality
standards. Several residents also expressed reservations about the permanent
sealing of their private wells because of the expense of using EWC water.
Additionally, the Township and a number of residents believe that some residents
have been compensated insufficiently in the past for the costs of service
connection installations. EPA responded that Superfund is not used for
reimbursement programs, and that future reimbursement of residents is an issue
for the State.
Description of Selected Remedy
The alternative selected for this operable unit (Alternative 3) included
extending the EWC Distribution System, providing service connections to all
residents currently using wells that are or could be contaminated, and sealing
individual contaminated wells. This remedy represents the first operable unit

of a permanent remedy for the MTHD/RHMW sites. Identification of sources of
contamination and possible remediation of the ground-water plume will be
addressed in a subsequent ROD.
The chosen remedy is the most cost-effective solution, is expected to
attain ARARs, is implementable and technically feasible, and will provide a
permanent solution to the problem of potential exposure of MTHD residents to
contaminated ground water.

RENORA, INC., SITE
EDISON TOWNSHIP, NEW JERSEY
HRS Score: 40.44 NPL Rank: 378
Background
The Renora, Inc., site, located in Edison, New Jersey, comprises one acre
of land in an area zoned for light industry. A small commercial complex is
adjacent to the site, and a residential area, containing a nursery school, a
senior citizens' center, and an apartment complex, lies nearby. All ground
water from the site discharges into Mill Brook, which borders the site.
Between 1978 and 1982, the site was used by Renora for storage, and
ultimately disposal, of materials containing hazardous substances. An
inspection of the site by the New Jersey Department of Environmental Protection
(NJDEP) in 1978 detected minor spills. A subsequent spill prompted NJDEP and
the Edison Township Department of Health and Human Resources (DOH) to
investigate the site, resulting in an order to remove all contaminated soil and
drums. In 1980, the NJDEP ordered Renora to cease all operations and implement
remedial actions at the site. Although Renora and the NJDEP agreed on a site
cleanup schedule shortly thereafter, Renora stopped cleanup activities due to
lack of funds. Renora abandoned the site in June 1982 and EPA included it on
the NPL 6 months later.
In 1984, EPA issued to all known potentially responsible parties (PRPs) an
administrative order to cleanup the site. A removal action, conducted by PRPs
between October 1984 and April 1985, removed liquid containerized wastes, PCB-
contaminated waste oil, and visibly contaminated soils. The PRPs conducted a
remedial investigation/feasibility study (RI/FS) of the site between May 1985
and May 1987 under EPA oversight. In support of the RI/FS, EPA conducted an
endangerment assessment to determine risks posed by the site. Based on
discussions following completion of the FS, the PRPs appeared to be willing to
implement the selected remedy. The ROD was signed on September 29, 1987.
Description of Site Work
Results of the RI indicated that the bulk of contamination at the site is
in the soil. Surficial soils (0-2 feet) contain PCBs, polyaromatic hydrocarbons
(PAHs), and to a lesser extent, volatile organic compounds (VOCs) and heavy
metals. Shallow ground water beneath the site is contaminated with low levels
of the VOC chloroethane and heavy metals. Surface-water and sediment samples
show levels of heavy metals, tetrachloroethane, and pesticides. However,
contaminant levels in upstream and downstream surface water and sediment samples
were not significantly different.
EPA's endangerment assessment revealed that the most significant threat to
human health is the possibility of direct contact with contaminated soils.
Trespassers, on-site workers, and future residents of the property are at the
highest level of risk.
185

Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
To address site contamination, EPA evaluated eight alternative remedial
action approaches on the basis of effectiveness, implementability, cost, and
compliance with other CERCLA mandates. EPA chose the following alternatives for
evaluation:
(1) No action, with periodic ground-water monitoring;
(2) Capping the site, with periodic ground-water
monitoring;
(3) Excavation of PCB-contaminated soils, partial
excavation of PAH-contaminated soils, off-site
disposal, and ground-water monitoring;
(4) Excavation of PCB-contaminated soils and off-site
disposal, partial excavation and biodegradation of PAH-
contaminated soils, and ground-water monitoring;
(5) Excavation of PCB-contaminated soils and off-site
disposal, and excavation and biodegradation of P.AH-
contaminated soils;
(6) Excavation of PCB- and PAH-contaminated soils and off-
site disposal, slurry wall installation, and ground-
water pumping and on-site treatment;
(7) Excavation of PCB-contaminated soils and off-site
disposal, excavation and biodegradation of PAH-
contaminated soils, and slurry wall installation; and
(8) Excavation and off-site disposal of all contaminated
soils, slurry wall installation, ground-water pumping,
and on-site treatment.
The alternatives were evaluated according to the extent to which they
attain Federal and State applicable or relevant and appropriate requirements
(ARARs). Remedial actions such as excavation, treatment, and disposal of waste
are subject to a number of requirements under the Resource Conservation and
Recovery Act (RCRA). Ground-water contaminant levels are regulated under the
Safe Drinking Water Act (SDWA) and New Jersey Ground-water Standards. State
criteria, advisories, and guidance governing the soil contaminants, PCBs, and
PAHs, although not strictly ARARs, were utilized in the remedy selection
process.
In choosing an appropriate remedy, EPA tried to maximize public and State
involvement. "Public acceptance" and "State acceptance" were two criteria used
to evaluate each alternative. EPA held a comment period in the fall of 1987 and
a public meeting on September 1, 1987, to address questions concerning the
remedial alternatives.
186
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Selected Remedy
After considering the eight alternatives, EPA selected Alternative 5, which
involved excavation of PCB-contaminated soils, biodegradation of PAH-
contaminated soils, and use of ground water as an irrigation medium in the
bioremediation system. Excavation of PCB-contaminated soils is expected to
reduce PCBs to targeted treatment levels, providing a permanent reduction in the
volume of contaminants to the maximum extent practicable. Remaining
contaminants will be subject to bioremediation, which is considered an
innovative technology. Implementation of the bioremediation system will
significantly and permanently reduce the toxicity, volume, and mobility of the
remaining contaminated soil at the site. The selected remedy is expected to
attain ARARs.

WALDICK AEROSPACE DEVICES SITE
SOURCE CONTROL OPERABLE UNIT
WALL TOWNSHIP, NEW JERSEY
HRS Score: 44.86 NPL Rank: 271
Background
The Waldick Aerospace Devices site is an inactive industrial facility
located in Wall Township, Monmouth County, New Jersey, 60 miles northeast of
Philadelphia. From 1979 to 1984, Waldick Aerospace Devices, Inc., manufactured
and plated metal components at the 1.75-acre site. Based on a referral from a
former Waldick employee, the New Jersey Department of Environmental Protection
(NJDEP), the Monmouth County Division of Criminal Justice (MCDCJ), and the
Monmouth County Board of Health (MCBH) conducted an initial inspection of the
facility in June 1982. This inspection revealed that Waldick was discharging
wastewater containing heavy metals, organic solvents, and oil products directly
onto the ground around the main manufacturing building. In addition, 2,100
square feet of soils at the rear of the plant appeared to be saturated with oil,
and 30 to 40 drums were scattered across the site.
In October 1982, NJDEP ordered Waldick Aerospace to clean up the site. In
January 1983, under the supervision of NJDEP, the company installed four on-site
monitoring wells. Subsequent sampling in early 1983 indicated that soil and
ground water were contaminated with heavy metals and organic compounds. In June
1983, Waldick removed 80 cubic feet of visibly contaminated soil and stored the
excavated material on a polyethylene membrane until it was disposed of off site
in 1984.
In March 1984, the State prosecuted Waldick Aerospace and its sister
company, KLS Industries, for criminal violation of Federal and State
environmental laws. The court ordered both corporations to pay all financial
obligations rendered and to clean up the site by September 1984. In October
1984, MCBH inspectors observed that, despite the removal of the pile of
excavated material and drums, the ground water below the sit€> had become
contaminated with cadmium at levels 300 to 1,200 times higher than National
Primary Drinking Water Standards. MCBH recommended additional downgradient
excavation and another round of soil samples; to date, KLS has neither responded
to MCBH requests nor taken further remedial actions.
MCBH identified and notified five other potentially responsible parties
(PRPs), but none has chosen to become involved in any remedial activities. In
November 1985, EPA initiated a remedial investigation/feasibility study (RI/FS)
to identify source control remedial alternatives. Off-site migration of
contaminants will be addressed in a future operable unit. The RI/FS for the
source control operable unit was completed in July 1987, and the ROD was signed
in September 1987.
188
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Site Work
The EPA lead RI revealed three distinct areas of contamination in the soils
along the west, south, and east sides of the buildings. EPA designated the
western areas as Area 1, and the southern and eastern areas as Area 2. Area 1
was contaminated mainly with volatile organic compounds (VOCs) and petroleum
hydrocarbons (PHCs); Area 2 contained high levels of cadmium and chromium, as
well as VOCs and PHCs. Contaminant pathways for the soil contaminants include
overland flow, ground-water flow through an aquifer beneath the site to a nearby
brook, and direct contact with soil. The brook is known to be contaminated with
a wide variety of compounds, but the RI could not determine the extent of the
contaminated ground-water plume.
Although the RI examined all contaminated media, only the soils and
buildings could be characterized sufficiently to proceed with the FS. EPA
decided to address these sources of on-site contamination in a source control
operable unit.
Description of Feasibility Study
To mitigate contamination of on-site soil and buildings the FS developed
the following remedial alternatives:
(1) No action;
(2) Improvement of site security, and monitoring of ground
water;
(3) Containment of contaminated soil with a slurry wall and
surface cap;
(4) In situ air stripping of Area 1 and excavation and
vitrification of Area 2;
(5) In situ air stripping of Area 1 and excavation and
incineration of Area 2;
(6) In situ air stripping of Area 1 and excavation,
removal, and off-site disposal of Area 2; and
(7) In situ air stripping before excavation and removal of
contaminated soils in Areas 1 and 2 for off-site
disposal.
The applicable or relevant and appropriate requirements (ARARs) identified
for the site include the Coastal Zone Management Act and Resource Conservation
and Recovery Act (RCRA) land disposal restrictions. Because neither Federal or
State contaminant-specific ARARs for soils have been established, NJDEP cleanup
objectives will be utilized as the soil standards for the site.
189

Progress Toward Implementing Superfund: Fiscal Year 1987
EPA held a public meeting in 1985, to present the RI/FS work plan, and in
1987, to present the results of the RI/FS. EPA also conducted numerous informal
meetings to inform the public of the site's history and its current status.
Description of Selected Remedy
The source control operable unit remedy selected for the site (a
modification of Alternative 5) included the following actions:
• In situ air stripping treatment of contaminated soils,
and excavation and off-site disposal of all treated
soils with residual contamination above action levels;
• Appropriate remediation of on-site buildings by
decontamination or demolition; and
• Installation of additional ground-water monitoring
wells, environmental monitoring, site fencing, and well
restrictions.
Ground water, surface water, and stream sediments will be addressed in a future
operable unit, which will focus on the off-site migration of contaminants.
The local community is in agreement with the source control action; some
residents expressed concern about their drinking water and whether the buildings
would be safe for occupancy after decontamination. EPA assured residents that
ground-water investigations would continue, and that decontamination procedures
were expected to make the buildings safe for future use.

WILLIAMS PROPERTY SITE
MIDDLE TOWNSHIP, NEW JERSEY
HRS Score: 40.45 NPL Rank: 377
Background
The Williams property site is located in Middle Township, Cape May County,
New Jersey, 60 miles southeast of Philadelphia. The 5.6-acre tract of wooded
land contains a well and a single residence owned by the Williams family.
Widespread dumping of refuse and construction debris has been occurring at the
site for an unknown period of time. In August 1979, approximately 150 drums of
liquid chemical wastes and sludge were emptied on the property adjacent to the
Williams residence. In response, the New Jersey Department of Environmental
Protection (NJDEP) undertook extensive investigations to determine the
environmental impact of the spill. These investigations revealed that surficial
sludge, underlying soil, and ground water were contaminated with organic
chemicals.
During June 1980, NJDEP initiated an emergency cleanup of the spill site,
removing 1,200 cubic yards of sludge and soil. Subsequent domestic-water
monitoring revealed little or no evidence of contamination until 1984, when
contaminant levels in a well at the Williams site increased sharply. The county
health department subsequently closed the well. The residents located near the
Williams property have been provided with municipal water, and the private wells
at these homes are no longer in use.
Two potentially responsible parties (PRPs) identified for the site included
the property owner and the generator of the hazardous substances. The property
owner is not financially viable, and NJDEP could not reach an agreement with the
generator to conduct the remedial investigation/feasibility study (RI/FS).
Through a cooperative agreement with the EPA, NJDEP completed an RI/FS for the
site in July 1987. The ROD for the site was signed September 30, 1987.
Description of Site Work
The State lead RI revealed a plume of organic contaminants in the ground
water beneath the site. The plume originated from the area of the 1979 spill,
although the RI revealed that the 1979 spill was not the only source of plume
contaminants. The plume extended 600 feet to the northeast in the Holly Beach
Aquifer. Because the ground-water plume was migrating (at a rate of 90 to 200
feet per year), the concentration of contaminants was increasing at downgradient
wells and decreasing at upgradient wells. The population threatened by exposure
to the contaminated plume included all downgradient private well users not
supplied with city water. Downgradient homes in the immediate vicinity of the
site had been connected to a municipal water supply.
The top 2 feet of soil at the site also was found to be contaminated with
phthalate, tetrachloroethane, and xylene at levels exceeding New Jersey soil
cleanup criteria. Populations at risk of exposure from direct contact with the
soil included nearby residents and visitors. The RI estimated that the
permanent population within 1 mile of the site was 485, with a peak summer
campground population of 4,738.
191

Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
Based on the results of the RI, the State lead FS identified the following
remedial response objectives: (1) remediate and mitigate migration of
contaminated ground water; (2) mitigate leaching of contaminated soil into
ground water; and (3) prevent direct contact with contaminated soil.
Technologies were selected and screened based on CERCLA criteria and site-
specific conditions. The following alternatives, in addition to a "no action"
alternative and institutional controls alternative, were developed and retained
for detailed analysis:
(1) Ground-water remedial alternatives:
• Extraction, air stripping, and recharge;
• Extraction, carbon adsorption, and recharge;
• Extraction, air stripping, carbon adsorption, and
recharge;
• Extraction, air stripping, carbon adsorption,
precipitation, flocculation, sedimentation, and
recharge;
• Extraction, air stripping, precipitation, flocculation,
sedimentation, and recharge;
• Extraction, carbon adsorption, precipitation,
flocculation, sedimentation, and recharge; and
• Extraction, air stripping, carbon adsorption, ion
exchange, and recharge.
(2) Soil remedial alternatives:
• Excavation, disposal in off-site permitted landfill,
surface grading, and revegetation;
• Excavation, disposal in on-site landfill, surface
grading, and revegetation;
• Installation of vacuum extraction well and soil
vacuuming system;
• Excavation, off-site incineration, surface grading, and
revegetation;
• Excavation, on-site incineration, surface grading, and
revegetation; and
• In situ destruction.
192

Progress Toward Implementing Superfund: Fiscal Year 1987
Federal applicable or relevant and appropriate requirements (ARARs)
identified for the site included Resource Conservation and Recovery Act (RCRA)
air emission standards and Safe Drinking Water Act (SDWA) Maximum Contaminant
Levels (MCLs). State ARARs included ambient air quality standards, volatile
organic substance standards, air stripping permitting requirements, and ground-
water and soil treatment standards.
In public meetings held concerning RI/FS results, the local community
expressed no strong positive or negative feelings about any of the remedial
alternatives, but were concerned mainly about the time required for site
cleanup. There was virtually no criticism of the selected remedy.
Description of Selected Remedy
The remedy selected for the site included the following activities:
• Ground-water extraction, treatment by air stripping and
carbon adsorption, and discharge to the aquifer; and
• Soil excavation and off-site incineration, site
restoration, and provision of an alternate water supply
for the Williams residence.
This remedy represented a permanent solution for the site and protects human
health by removing the contaminants from the ground water and removing any
residual source of continuing contamination from the site. The remedy is cost-
effective and is expected to attain ARARs.

ENDICOTT VILLAGE WELL FIELD SITE
ALTERNATIVE WATER SUPPLY OPERABLE UNIT
VILLAGE OF ENDICOTT, NEW YORK
HRS Score: 35.57 NPL Rank: 507
Background
The Endicott Village Well Field is located in the Village of Endicott in
Broome County, New York. The site consists of a well and associated ground-
water contamination. The well field site is located near industrial tracts and
landfills including Endicott landfill, which was identified as the probable
source of contamination. No private homes are located in the site area.
The well operated from 1950 to the present, drawing water primarily by
infiltration from the nearby Susquehanna River. Currently, the well delivers
approximately 47 percent of the total water supply to the Endicott municipal
system. In May 1981, following a chemical spill in Endicott, EPA sampled wells
and detected vinyl chloride and trace amounts of other volatile organic
contaminants (VOCs) in the well water. The Public Works Department for the
Village of Endicott undertook several site remediation efforts, including
installation of an aeration system and a purge well to capture the contaminant
plume. Despite the remediation efforts, the Maximum Contaminant Level (MCL) for
vinyl chloride has been exceeded in ground-water discharge on several occasions.
Because of the threat to drinking water supplies, EPA initiated remedial
actions as an operable unit to provide safe drinking water to the community.
The EPA lead remedial investigation/feasibility study (RI/FS) for this operable
unit was completed in July 1987 and the ROD was signed September 25, 1987. A
supplemental RI/FS for a second operable unit has been initiated to evaluate the
nature and extent of contamination, to evaluate possible source control
measures, and to further investigate source areas and companies that have been
identified as contributing hazardous waste to the Endicott landfill. Notice
letters will be sent out to potentially responsible parties (PRPs) after the
supplemental RI/FS, as appropriate.
Description of Site Work
The primary objective of the RI for the first operable unit was to identify
the source of contamination to the well. The RI indicated that the most
probable source was the landfill, particularly when inundated by the Susquehanna
River during floods. The primary potential human health impact at the site was
through ingestion of contaminated ground water. Contaminants of concern were
determined to be various organic compounds. Of these chemicals, only vinyl
chloride was occasionally present at levels exceeding applicable or relevant and
appropriate requirements (ARARs) for the site.
Description of Feasibility Study
The objective of the FS for the first operable unit was to develop short-
term remedial alternatives capable of providing a safe drinking-water supply to
t94
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
the community. Seven alternatives were developed and evaluated against
criteria mandated by CERCLA:
(1) No action;
(2) Installation of purge wells only;
(3) On-site treatment of ground water via air stripping and
discharge to the distribution system of the Village of
Endicott;
(4) Alternative 3 with additional purge wells;
(5) Installation of a new Endicott supply well;
(6) Construction of a new treatment plant; and
(7) Connections to the surrounding community supply.
As mandated by CERCLA, remedies must use permanent solutions and treatment
technologies to the maximum extent practicable, and must also attain ARARs.
ARARs identified for the site include the MCL for vinyl chloride and the Federal
Water Quality Criteria for the other VOCs. Other ARARs include New York State
guidelines for air emissions from air strippers, and the National Emission
Standard for Hazardous Air Pollutants (NESHAPS) for vinyl chloride.
The remediation efforts conducted at the site by community officials has
reduced the level of public concern over the contamination at the well. A
public meeting was held on August 11, 1987, to discuss the results of the RI/FS.
Description of Selected Remedy
The remedy selected for the site (Alternative 3) consists of four
components:
• Treatment of the ground water, by means of air
stripping, and subsequent discharge of the treated
water to the distribution system of the Village of
Endicott for use as drinking water;
• Continued operation of the purge well by the Village;
• Continued monitoring for VOCs by the Village; and
• Initiation of a supplemental RI/FS with the New York
State Department of Environmental Conservation (NYSDEC)
as lead agency.
The selected remedy is designed as a short-term remedial measure operable unit
and utilizes an alternative treatment technology to the maximum extent practi-
cable. The selected remedy is expected to be protective of human health and the
environment, to be cost-effective, and to attain all Federal and State ARARs.

G.E. MOREAU SITE
MOREAU, NEW YORK
HRS Score: 58.21 NPL Rank: 52
Background
The GE Moreau site in Moreau, New York, 30 miles north of Albany, was used
as an industrial waste disposal site from 1958 to 1968. An evaporative pit at
the site received approximately 452 tons of waste material generated by the
General Electric (GE) Company, including trichloroethylene (TCE), PCBs, spent
solvents, oils, sludges, and other miscellaneous waste. The site was included
in a September 1980 Consent Order with the New York State Department of
Environmental Conservation (NYSDEC) whereby GE would conduct investigations at
seven waste disposal sites in the area and contain the waste materials at these
sites.
In late 1982, it was determined that there were elevated levels of TCE in
the ground water at the site. As a result, the Town of Moreau installed
activated carbon filter systems on the drinking water systems of 70 homes
believed to be downgradient from the site. In the summer of 1983, EPA
negotiated with GE to address the off-site contamination problems. These
negotiations resulted in the signing of an Administrative Order in November
1983, under which GE agreed to: 1) install and maintain activated carbon filter
systems on homes whose well contamination exceeded specified levels; 2) sample
and analyze on a monthly basis drinking water in homes downgradient from the
site on a monthly basis until full remediation is completed; 3) conduct a
remedial investigation/feasibility study (RI/FS); 4) design and construct the
EPA-selected remedy; and 5) conduct post-remediation monitoring and operation
and maintenance. GE's RI/FS was completed in August 1985 and the resulting ROD
was signed September 25, 1987.
Description of Site Work
The RI conducted by GE consisted of a complete characterization of the
aquifer, including ground-water flow and contaminant transport phenomena. The
RI indicated that a contaminant plume approximately 4,800 feet long and up to
2,000 feet wide of volatile organic compounds (VOCs) emanated from the site.
The plume originated at the GE Moreau site and followed the regional ground-
water flow, extending to surface-water streams feeding the New Reservoir. TCE
was the most prevalent organic contaminant, found at levels up to 81 ppm. The
RI also showed TCE and dichloroethylene contamination (up to 900 ppb) in Reardon
Brook, which feeds public water supply reservoirs of a nearby town. The RI also
identified 8,600 cubic yards of PCB-contaminated soils in the dirt roads leading
to the GE Moreau site.
Description of Feasibility Study
The primary purpose of the FS was to identify remedies that would ensure
a safe drinking water supply for residents whose drinking water wells had been
adversely impacted by ground-water contamination emanating from the site. Other
objectives of selected remedies would include remediating the water quality of
Reardon Brook and reducing the potential for exposure to PCB-contaminated soils
196

adjacent to the GE Moreau site. Based on these objectives, the following
remedial alternatives were developed:
(1) Surface-water Supply:
• Activated carbon adsorption; and
• Air stripping;
(2) Residential Water Supply:
• No action;
• Ground-water monitoring only;
• Ground-water pumping and recharge;
• Individual whole house treatment; and
• Provision of an alternate water supply;
(3) Aquifer Restoration:
• Source containment, ground-water monitoring, air
stripping, and discharge; and
• Source containment, and ground-water pumping and
recharge;
(4) Soil Remediation:
• Excavation and on-site soil disposal;
* Excavation and off-site soil disposal; and
• Surface sealing of soils.
CERCLA requires that selected remedies attain applicable or relevant and
appropriate requirements (ARARs). The ROD identified several Federal and State
requirements only as "relevant and appropriate," including Safe Drinking Water
Act (SDWA) Maximum Contaminant Levels (MCLs), and New York State Ambient Water
Quality Standards and guidance values.
EPA conducted numerous meetings with citizens groups and public officials.
The Town Board of Moreau requested that EPA require a new or modified RI/FS
report, on the basis that the report was inadequate in three areas: the
provision of alternative water sources; the definition of the contaminated area;
and the restoration of the aquifer. The town asserted that the plume emanating
from the site had migrated from the area defined as "contaminated" by the RI/FS.
EPA informed the town that the contaminated areas had been defined properly.
The Town of Moreau never shared any evidence of the alleged plume migration, and
EPA never revised the mapping of the plume. EPA is completely satisfied with
the results of the RI/FS report prepared by GE and adopts it as conclusive.
Description of Selected Remedy
The selected remedy for the site included the following actions:
• Treating Reardon Brook waters through air stripping;
• Providing an alternative water supply for residences
with potentially contaminated drinking water wells;
197
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
• Restoring the aquifer through source containment,
ground-water monitoring, air stripping, and discharge;;
and
• Excavating PCS-contaminated soil and storing the soil
onsite behind an existing slurry wall.
These activities are expected to be consistent with the technical
requirements of both State and Federal environmental laws, are cost-effective,
and provide adequate protection of public health, welfare, and the environment.

HAVILAND COMPLEX SITE
TOWN OF HYDE PARK, NEW YORK
HRS Score: 33.62 NPL Rank: 607
Background
The Haviland Complex site is located in the Town of Hyde Park in Dutchess
County, New York. The 275-acre site includes an apartment complex, an
elementary school, a shopping center, and a number of private residences. There
are residential and non-residential wells on the site whose water is drawn from
an aquifer that underlies the site.
The Haviland Complex Apartments were constructed in the 1960s, in proximity
to an existing shopping center and local residences. The shopping center
contains a laundromat and dry cleaner, both of which have been in business since
the 1960s. Complaints about the quality of ground water from apartment
residents began in October 1981. Allegations about a failure of the
laundromat's sewage disposal system were the impetus for Dutchess County and the
New York State Department of Environmental Conservation (NYSDEC) to begin
testing the quality of the ground water at the.site. These tests indicated that
the sewage systems of the dry cleaner and of a nearby car-washing business had
deteriorated and that these systems were at least contributing to the site's
ground-water problems.
NYSDEC conducted further tests in 1982 because of the concern about
potential contamination of ground water with volatile organic compounds (VOCs)
from the laundromat's sewage system. As a result of this testing, NYSDEC
recommended that the City disconnect its public water system from a well near
the apartment complex, and that the laundromat implement a pretreatment system.
In June 1985, NYSDEC asked EPA to perform a removal action to provide all
residents with potable water. EPA declined to conduct a removal action because
the site did not meet the necessary criteria (specifically, because
contamination levels at the site did not exceed EPA's 10-day Health Advisory
levels for drinking water). EPA listed the site on the NPL in October 1985 and
in August 1986 began a remedial investigation/feasibility study (RI/FS) of
source control options and of providing an alternative water supply. The ROD
was signed September 30, 1987.
Description of Site Work
The New York State lead RI indicated that the source of contamination was
broader than the NYSDEC tests indicated, and appeared to include several septic
systems in the area, including those of businesses connected to the Haviland
Shopping Center (e.g., car wash and laundromat), Haviland Complex Apartments,
and the Haviland Junior High School. The primary environmental exposure routes
of chemical contamination at the site were drinking ground water and inhaling
VOCs while showering. Vinyl chloride was the contaminant that presented the
highest potential risk to public health.

-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
The objective of the FS was to evaluate and recommend a cost-effective
remedial action that would minimize the risk to public health and the
environment and meet the statutory requirements of CERCLA. Remedial action
alternatives were subjected to a preliminary screening based on technical
feasibility and other criteria. Of the original 11 alternatives, 5 remained
after the screening:
(1) No action;
(2) Source control, including excavation of contaminated
dry wells and septic disposal systems;
(3) Ground-water extraction, treatment, and discharge to
surface waters;
(4) Ground-water extraction, treatment, and discharge to
public water supply; and
(5) Provision of public water supply to all private well
users in the study area.
The FS also identified potential applicable or relevant and appropriate
requirements (ARARS) that the remedial action must meet as mandated by CERCLA.
Federal ARARs included Maximum Contaminant Levels (MCLs) established under the
Safe Drinking Water Act (SDWA), ambient water quality standards set under the
Clean Water Act (CWA), and ground-water discharge standards set under the
National Pollutant Discharge Elimination System (NPDES) . State ARARs included
New York Ground Water Standards and New York Surface Water Quality Standards.
The primary concern of residents expressed throughout the RI/FS process was
that a safe water supply be provided. The public also was concerned about the
possibility that exposure to VOCs might have long-term effects. Some
individuals were extremely active in voicing their concerns by holding meetings
and attending Town Council sessions. EPA held a public meeting on August 17,
1987, to discuss the findings of the RI/FS.
Description of Selected Remedy
The remedy selected for the Haviland Complex site was a combination of
three alternatives: source control (Alternative 2), aquifer restoration
(Alternative 3), and provision of an alternative water supply for area residents
(Alternative 5). Specifically, ground-water extraction wells will be placed on
site to contain the contaminant plume, and VOCs will be extracted from ground
water by means of a packed tower air stripper. Residents also will be connected
to the public water service.
The remedy is expected to meet all Federal and State ARARs within 5 to 10
years. The remedy also is cost effective, protective of human health and the
environment because it reduces public exposure to contaminated ground water, and
uses a combination of permanent and alternative treatment technologies to the
200

maximum extent practicable. Residents and the State of New York were consulted
and concurred with the remedy selected.

KATONAH MUNICIPAL WELL SITE
BEDFORD, NEW YORK
HRS Score: 3535 NPL Rank: 527
Background
The Katonah Municipal Well site is located in the Village of Katonah in the
Town of Bedford in Westchester County, New York. The well itself is located on
a peninsula that extends into the Muscoot Reservoir, a source of drinking water
for New York City. The well supplies water to the residents of Katonah, drawing
water primarily from the reservoir, with some contribution from an aquifer
underlying the village.
The discovery of contaminants in a well supplying the nearby City of
Brewster prompted the Westchester County Department of Health (WCDH) to survey
a number of drinking water wells in the area in the fall of 1978. Samples taken
from the Katonah Well revealed the presence of halogenated organics, including
tetrachloroethylene, at levels exceeding New York State Department of Health
standards for drinking water.
Several sources of the contamination were identified. The New York State
Department of Environmental Conservation (NYSDEC) traced the contamination to
the disposal facility of a waste hauler who had collected wastes from the septic
systems of dry cleaners in the village of Katonah. Also, sampling data later
confirmed claims that Bedford town employees had dumped waste solvents down a
drain located less than 100 feet from the Katonah Well.
The well was closed in December 1978 and the town developed an alternate
water supply by installing another well. In addition, the WCDH began source
control measures. Dry-cleaning establishments were required to pump out the
septic systems and modify their disposal techniques. Initial attempts by the
Town and WCDH to remove contaminants failed, however, and the site was referred
to NYSDEC for evaluation.
Notice letters were sent to four dry-cleaning establishments and three
property owners identifying them as potentially responsible parties (PRPs). A
special notice letter, concerning the solvent dumping by town employees, was
sent to the Town of Bedford. The site was placed on the NPL in June 1986. The
NYSDEC and EPA entered into an agreement in which EPA assumed responsibility for
cleanup of the contamination. The remedial investigation/feasibility study
(RI/FS) was completed in June 1987 and the ROD was signed September 25, 1987.
Description of Site Work
Results of the EPA lead RI/FS indicated that only tetrachloroethylene, the
original contaminant of concern, appeared consistently in the sampling data at
levels that exceeded standards established for the site. Tetrachloroethylene
was found in levels in ground water and soils above the New York State
Department of Health and NYSDEC Technical and Operational Guidance Series and
a Federal Water Quality Criteria Value for any single volatile organic compound.
202
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
The risk assessment in the RI indicated that the primary potential human
health risk was through ingestion of contaminated ground water. The data from
the Katonah Well indicated that there was a lifetime excess cancer risk of
1CT5 associated with ingestion of the water from the Katonah Well. The only
potentially affected surface waters are the Katonah Brook and nearby reservoir.
Sampling indicated that these bodies have not been affected by the contamination
and the potential for future contamination is low.
Description of Feasibility Study
The EPA lead FS identified and evaluated remedial alternatives for the site
with respect to criteria in CERCLA and the NCP. Seven alternatives were
evaluated:
(1) No action;
(2) Excavation of the soils and off-site disposal;
(3) Excavation of the soils and off-site incineration;
(4) Extraction, treatment, and discharge of ground water
to public water distribution system, and containment
of soils with synthetic liner and clean cover material;
(5) Alternate water supply via relocation of new well;
(6) On-site treatment of ground water via air stripper, and
discharge to public water drinking system; and
(7) Renovation of existing Katonah Well and on-site
treatment with air stripper.
Alternatives were evaluated in terms of practicability, implementability,
and cost-effectiveness, and for compliance with the CERCLA requirement that
remedies attain Federal and State applicable or relevant and appropriate
requirements (ARARs) and utilize permanent solutions and alternative treatment
technologies to the maximum extent practicable. ARARs at the site include the
Federal Water Quality Criteria of 10"6 excess cancer risk for
tetrachloroethylene, and a State requirement concerning air emissions from the
packed air stripper.
Community involvement at Katonah was limited. Local officials have
received few complaints regarding the site since the well was shut down in 1978.
Public meeting attendance was limited to town officials and one PRP. Specific
concerns raised during the public comment period included the physical and
financial impacts of the remedial action on Katonah1s Commercial Center, the
relationship of Katonah Well to the current municipal water supply, and Federal,
State, and county jurisdictional issues.
203
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Selected Remedy
The selected remedy for the site is Alternative 6. A new production well
and a ground-water treatment facility that employs air stripping techniques will
be installed at Katonah Well. A water quality monitoring program will be
instituted, and a general cleanup of the area around the pump house was
recommended.
The alternative addresses aquifer restoration and utilizes alternative
treatment technologies to the maximum extent practicable to reduce the toxicity,
mobility and volume of contaminants. It is expected to be protective of human
health and the environment, to be cost-effective, and to attain all Federal and
State ARARs.

SUFFERN VILLAGE WELL FIELD SITE
SUFFERN, NEW YORK
HRS Score: 35.57 NPL Rank: 506
Background
The Suffern Village Well Field site in the Village of Suffern, Rockland
County, New York, encompasses 30 acres in the Ramapo River Valley. Four
production wells in the well field provide water to approximately 12,000 people.
Recharge to the wells is derived mainly from induced infiltration of water from
the Ramapo River. The Ramapo River is categorized by the State as a Class A
water body, best utilized for potable water supply.
In September 1978, volatile organic compounds (VOCs) were detected in tap
water collected from the municipal distribution system. Subsequent monitoring
of the site confirmed that ground water had become contaminated with 1,1,1-
trichloroethane (TCEA) and trace amounts of other VOCs. Three of the four wells
were found to have TCEA at levels above New York Department of Health guidelines
and were shut down. A survey of local industries indicated that the Tempcon
Corporation, a small oil burner reconditioning business, had used TCEA prior to
the contamination discovery. Tempcon subsequently ceased using a seepage
disposal pit as well as TCEA-based cleaning products.
In March 1979, initial remedial activities were conducted under the
guidance of the Rockland County Health Department (RCHD). Waste materials were
removed from the disposal pit and contaminated soil was excavated and
devolatilized. However, these initial remedial activities did not remove the
ground-water contamination. Later that year, the Village constructed a spray
aeration treatment system to remove the TCEA from the municipal water supply.
The site was placed on the NPL in October 1984.
Since Tempcon ceased disposal activities, the water quality of the wells
has gradually improved. Monitoring results in early 1985 indicated that the
aeration treatment was no longer needed, and two wells were brought back into
service. Since May 1985, the TCEA concentrations in all four wells have
remained below State guidelines with only occasional exceptions. Nevertheless,
the complexity of the site hydrogeology led to the belief that even though the
suspected source had been remediated, slugs of contaminants may have been
released into the subsurface, thereby causing the well field to be under the
continual threat of periodic contamination.
EPA signed a cooperative agreement with New York State in March 1985 to
undertake the remedial investigation/feasibility study (RI/FS). Although
Tempcon was identified as a potentially responsible party, it did not
participate in the RI. The ROD was signed September 25, 1987.
205
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Site Work
The RI was initiated in April 1986 and included soil and ground-water
sampling programs. TCEA and associated impurities were detected in several of
the monitoring wells, indicating that the supply wells still contain ground
water with concentrations up to 30 ug/L TCEA. At one location, concentrations
ranged from 30 to 1,500 ug/L. The only pathway of concern identified was
through ground-water migration from Tempcon and the area of high concentration.
Description of Feasibility Study
After an initial screening, five remaining remedial alternatives were
considered:
(1) No action;
(2) Treat the water supply using the existing spray
aeration system;
(3) Treat the water supply using a packed tower aeration
(PTA) system;
(4) Contain the plume, treat with a PTA system, and
discharge to the river; and
(5) Divert the plume, treat with a PTA system, and pump to
Suffern distribution system.
The five alternatives were evaluated based on a number of criteria. Applicable
or relevant and appropriate requirements (ARARs) identified included the Safe
Drinking Water Act (SDWA) and more stringent State guidelines. However, no
ARARs were predicted to be exceeded at the well head.
The local community's initial concern about contamination subsided after
a newspaper article in late 1978 reported that contamination levels had
decreased to a safe level. One public meeting was held in August 1987 to
present the findings of the RI/FS.
Description of Selected Remedy
A "no action" alternative, combined with monitoring of the ground water,
was selected for this site. Because natural processes will contribute to
reducing the toxicity and/or mobility of contaminants, this decision meets the
CERCLA requirement of reducing volume, toxicity, and mobility of contaminants.
In addition, although there is a statutory preference for treatment-based
remedies, the absence of a threat to human health and the environment in this
case renders treatment unnecessary. Furthermore, ARARs at the point, of ground
water are not now, and are not predicted to be, exceeded. In addition, this
alternative is the most cost-effective solution.
Because toxic, mobile contaminants will remain in some locations in the
aquifer for 5 years, the selected remedy includes restricting access to the
206
-------

aquifer. If monitoring of the site indicates contamination that might
jeopardize public health, a second operable unit may be initiated to remediate
further problems.

VOLNEY LANDFILL SITE
CONTAMINATION SOURCE OPERABLE UNIT
VOLNEY, NEW YORK
MRS Score: 32.89 NPL Rank: 627
Background
The Volney Landfill site, located in Volney, New York, 25 miles northwest
of Syracuse in Oswego County, covers 85 acres and includes an inactive, unlined
landfill. Land in the vicinity of the site is agricultural with a small
residential population. Twenty-five single-family residences using individual
wells have been identified as potential receptors of ground water from the
landfill. There is a stream/wetland ecosystem downgradient from the site.
The landfill operated from 1969 to 1983 under the ownership of the Oswego
Valley Solid Refuse Board and, beginning in 1975, Oswego County. Most of the
waste materials disposed of in the landfill consisted of typical residential,
commercial, institutional, and light industrial waste. During 1974 to 1975,
however, disposal of approximately 8,000 drums from the Pollution Abatement
Services (PAS) site was permitted by the New York State Department of
Environmental Conservation (NYSDEC). Allegedly, 50 to 200 of these drums
contained unidentified liquid waste, and their condition and location in the
landfill is unknown.
In the mid-1970s, as the landfill expanded, a leachate collection system
was installed at the site. Collected leachate from the site was treated at
several locations between 1979 and 1986. In March 1979, Oswego County and the
NYSDEC entered into a Consent Order that required the County to take a number
of corrective actions, including ground-water monitoring studies, evaluation of
leachate and sludge treatment, and the development of a closure plan. Waste
disposal continued at the Volney Landfill until September 1983. In the fall of
1985, closure operations for the landfill were completed by Oswego County.
The site was separated into two operable units because of the complexity
of the site conditions. Through a cooperative agreement with EPA, the NYSDEC
completed the first remedial investigation/feasibility study (RI/FS) for the
site in May 1987. This RI/FS addressed the source of contamination in order to
prevent further potential contaminant migration from the site, and to eliminate
the threat of direct contact. The ROD for this operable unit was signed July
31, 1987. A subsequent operable unit RI/FS will be conducted to address the
contamination pathways.
Description of Site Work
The RI conducted by NYSDEC detected a variety of hazardous substances in
ground-water monitoring well samples, including 17 volatile compounds, 14 semi-
volatile compounds, and 10 metals. Of these compounds, eight were detected at
levels in excess of either Safe Drinking Water Act (SDWA) Maximum Contaminant
Levels (MCLs) or Clean Water Act (CWA) Water Quality Criteria (WQC). Analysis
of surface-water samples indicated a generally lower incidence and concentration
of contaminants. In addition, RI analyses performed on stream sediment samples
208
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
indicated the presence of fewer hazardous substances than were found in the
ground-water or surface-water samples, although at somewhat higher
concentration.
The primary potential human health impact of the site is through
contamination of local ground water, which is a source of drinking water for
private well users in the area. No significant violation of drinking water
standards has yet occurred. Sampling conducted during the RI indicated that low
levels of surface-water contamination are not currently a threat to the wetland
and stream environment. However, an RI/FS planned for the surface-water
contaminant pathway will provide more definitive information.
Description of Feasibility Study
The major objective of the FS was to evaluate source control remedial
responses that address the source of contamination, prevent further contaminant
migration from the site, and minimize the threat to human health and the
environment. Technologies found to be compatible with the specific site
conditions and the remedial action objectives for the operable unit were
combined into source control alternatives. After an initial screening, the
following eight remedial action alternatives were subjected to detailed
evaluation:
(1) No action, with site monitoring;
(2) Excavation and off-site waste disposal;
(3) Supplementary capping of landfill side slopes;
(4) Slurry wall with leachate collection and off-site
leachate treatment;
(5) Slurry wall with leachate collection and on-site
leachate treatment;
(6) Supplemental capping and slurry wall with leachate
collection and off-site leachate treatment;
(7) Supplemental capping and slurry wall with leachate
collection and on-site leachate treatment; and
(8) On-site incineration.
Applicable or relevant and appropriate requirements (ARARs) considered in
the evaluation of these alternatives include Resource Conservation and Recovery
Act (RCRA) closure, off-site transportation and disposal, tank storage,
incineration, and technical landfill cover requirements; Occupational Safety and
Health Act (OSHA) regulations; and State pollution discharge elimination system
permitting requirements.
Throughout the Volney Landfill's history, community concern and involvement
have been high. Four principal citizens groups have been organized to address
209
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
the community concerns regarding the alleged disposal of PAS wastes at Volney
Landfill, Fulton Terminals, and the Clothier Disposal sites. The local
community is generally in agreement with the proposed remedy.
Description of Selected Remedy
The recommended alternative for this operable unit consists of leachate
collection, installation of a slurry wall, and capping of the landfill side
slopes. The combination of capping and leachate collection is expected to
provide a significant reduction in the volume and mobility of hazardous wastes,
thus meeting CERCLA statutory preferences for permanence. A recommendation for
leachate disposal was not made; leachate will be treated either on site or off
site. Both on-site and off-site leachate treatment provide the same degree of
remediation and have similar costs. A determination as to which option will be
selected will be made pending the results of the treatability studies to be
conducted during the remedial design.

VEGA ALTA PUBLIC SUPPLY WELLS
GROUND-WATER CONTAMINATION OPERABLE UNIT
VEGA ALTA, PUERTO RICO
MRS Score: 42.24 NPL Rank: 334
Background
The Vega Alta site consists of a public water supply well field located in
the municipality of Vega Alta, approximately 32 kilometers west of San Juan,
Puerto Rico. Ground water is the primary source of the public water supply for
the area. Major activities in the area include agriculture and light industrial
manufacturing which use chlorinated solvents. The Vega Alta municipal landfill,
located within part of the public well field, has been in operation since the
early 1970s and does not employ any leachate containment systems.
Contamination was first discovered in June 1983 during a survey conducted
by the U.S. Geological Survey (USGS). Volatile organic compounds (VOCs),
including trichloroethylene, were detected in the well field, and 2 of the 10
wells in the field were shut down by the Puerto Rico Aqueduct and Sewer
Authority (PRASA). The site was placed on the NPL in September 1983. Between
September 1983 and March 1984, the EPA Technical Assistance Team sampled water
from the field. Results indicated that the VOCs had not migrated and had been
reduced in concentration. An air stripper constructed by PRASA operated from
September 1984 to May 1985 at the Ponderosa well, the site of initial
trichloroethylene contamination.
The EPA lead remedial investigation/feasibility study (RI/FS) was initiated
in 1984. The USGS performed some of the sampling at the site under an
interagency agreement with EPA. The FS identified alternatives to address
ground-water contamination; source control actions will be considered in a
subsequent operable unit FS. Three potentially responsible parties (PRPs) were
identified from the local industrial plants and notice letters were sent in July
1984. None of the companies indicated a willingness to undertake cleanup
action. The ROD for the first operable unit was signed on September 29, 1987.
After the issuance of the ROD, EPA sent notice letters to all PRPs giving them
the opportunity to implement the remedy selected and participate in the second
operable unit RI/FS to investigate and remedy the sources of contamination.
Description of Site Work
The RI was performed from April 1984 to March 1985, and the final RI report
was released in May 1986. Results indicated that the contaminant plume had been
contained by the pumping of the well field, VOCs had decreased over time, and
the contaminant plume decreased by 58 percent in average concentration over the
16-month period. Consequently, VOC levels in the distribution system were below
action levels that would require a removal action.
The risk assessment at the site indicated that the primary exposure
mechanism and health risk is by ingestion of contaminated ground water, which
poses a maximum total carcinogenic risk of 1.5 x 10~A. The major contaminants
in the ground water are VOCs, particularly trichloroethane and
tetrachloroethane. The primary surface discharge points for contaminated ground
211
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
water are a marsh and the Atlantic Ocean. Consequently, no adverse
environmental effects are anticipated as a result of contamination released to
the environment.
Description of Feasibility Study
The major objective of FS was to evaluate remedial alternatives using a
cost-effective approach consistent with the goals and objectives of CERCLA. The
remedial response will address the management of contaminated ground water as
the first operable unit. A detailed analysis of alternatives considered the
following:
(1) No action with monitoring;
(2) Ground-water treatment with discharge to the PRASA
distribution system; and
(3) Ground-water treatment with surface-water discharge and
provision of an alternate water supply.
The alternatives were evaluated for compliance with applicable or relevant
and appropriate requirements (ARARs); reduction of toxicity, mobility or volume
of contaminants; short-term and long-term effectiveness and permanence;
implementability; cost; community and State acceptance; and overall protection
of human health and the environment.
ARARs for the ground-water cleanup included Safe Drinking Water Act (SDWA)
Maximum Contaminant Levels (MCLs), Maximum Contaminant Level Goals (MCLGs),
Ambient Water Quality Criteria (AWQC) adjusted for drinking water, EPA Drinking
Water Health Advisory, EPA Reference Doses, Puerto Rico Health Department
Administrative Order 10, and a cumulative health risk of 1CT6. Surface-water
ARARs included the National Pollution Discharge Elimination System (NPDES), AWQC
for aquatic life, and AWQC for human health. ARARs for air releases included
the Clean Air Act (CAA).
Meetings with citizens and local officials were held by EPA to discuss the
progress of the RI. The public comment period on the FS was extended following
a request by the PRPs. Comments on the FS included technical concerns regarding
the contaminants, PRP and legal issues, and health risks.
Description of Selected Remedy
Alternative 2 was the initial selected remedy for the site. The remedy
included ground-water treatment (by air stripping and carbon adsorption) at four
supply wells and discharge of the treated water to the distribution system.
Treatment would bring the water to the 10~6 ingestion risk level to meet all
ARARs. Comments received from the Puerto Rico Department of Health, PRASA, and
the Water Pollution Control Committee of Puerto Rico, however, resulted in
modification of the selected remedy. In addition to the treatment of four
public wells, two private-well users will be provided an alternate water supply
from the distribution system. Also, due to public concern, water from the
Ponderosa well will not: be discharged to the distribution system but rather to
212
-------
Progress Toward Implementing Super-fund: Fiscal Year 1987
surface water, in accordance with an existing NPDES permit. The alternative is
expected to comply with ARARs and reduces the toxicity, mobility, or volume of
contaminants.

KANE AND LOMBARD SITE
SOURCE CONTROL OPERABLE UNIT
BALTIMORE, MARYLAND
HRS Score: 30.15 NPL Rank: 724
Background
The Kane and Lombard site covers 8.4 acres of undeveloped land in the
southeast quarter of Baltimore, Maryland. The site is adjacent to a high school
and is located near a number of industrial, commercial, and residential
properties. Between 1962 and 1971, the site was excavated and refilled with
hazardous and solid waste; surface dumping of hazardous waste on the site
continued from 1971 to 1984. Several adjacent properties were also found to be
excavated and may have been used for waste disposal.
In 1980, Maryland inspectors observed 400 to 500 drums on the property,
many of which were damaged. After negotiating with the site owners, the State
issued a Complaint in 1983 ordering the owners to clean up the site. The State
was unsuccessful in forcing compliance, however, and in April 1984, requested
assistance from EPA. EPA authorized the immediate removal of over 1,000 drums
and 6 inches of soil beneath the drums. The site was stabilized by regrading
and capping.
In October 1984, the site was included on the NPL. EPA initiated a
remedial investigation/feasibility study (RI/FS) in October 1985, and a ROD
addressing source control was signed September 30, 1987. Adjacent properties
are being investigated by the State of Maryland. Because these other sites
contribute to ground-water contamination, complete ground-water remediation
activities were deferred pending completion of these other studies.
Description of Site Work
The EPA lead RI of ground-water and soil sampling indicated the presence
of over 50 organic compounds, including toluene, PCBs, ethylbenzene,
dichloroethane, vinyl chloride, and polynuclear aromatics. The most likely
routes of potential human exposure to contaminants were identified as use of
contaminated ground water and direct contact with contaminated soil.
Contaminants were detected in the upper two of three water-bearing zones beneath
the site. Because residents were supplied with drinking water from the City of
Baltimore, there was no immediate threat to the community. However, the ground-
water contamination threatened future use of the aquifers. Although there was
a potential threat of direct contact due to the proximity of the high school and
recreational facilities, the clay cap constructed in 1984 reduced that threat.
Description of Feasibility Study
The objective of the EPA lead FS was to identify alternatives that would
eliminate or reduce soil and ground-water contamination to acceptable risk-based
levels. Because the other potential hazardous waste sites in the area were
expected to contribute to ground-water contamination, the FS was limited to
consideration of source control technologies to reduce the problems resulting
from the Kane and Lombard site. Based on this objective, nine remedial
214
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
alternatives were identified, of which the following passed the initial
screening:
(1) No action, with drainage-way maintenance and long-term
monitoring;
(2) Construction of subsurface containment structures to
prevent ground-water migration, and construction of a
multi-layer cap;
(3) Excavation of all waste materials and on-site or off-
site incineration;
(4) Excavation of contaminated fill materials and
extraction (soil washing); and
(5) In situ vitrification.
Each of these alternatives was evaluated with respect to effectiveness,
implementability, and cost, and CERCLA requirements for permanent solutions, use
of treatment technologies to the maximum extent practicable, and ability to
attain applicable or relevant and appropriate requirements (ARARs). The ROD
indicated that because the remedy selected would not address complete ground-
water remediation, it would not attempt to ensure compliance with all ARARs for
the entire site. However, the ROD did not identify any of the ARARs that would
be pertinent to the entire site. Only the action-specific ARARs that would
apply to the selected remedy were presented (described below).
EPA held a public comment period from August 30, 1987 to September 28,
1987, and a public hearing was held on September 10, 1987. The primary concern
expressed by the public was the long-term health effects from contaminants left
on the site.
Description of Selected Remedy
The remedy selected (Alternative 2) involved:
• Removal of drums and contaminated hot-spots of soil;
• Construction of subsurface containment structures to
prevent ground-water migration;
• Construction of a multi-layer cap and drainage system;
and
• Continued ground-water monitoring.
The remedy is an interim measure to control contamination from the Kane and
Lombard site. Ground-water contamination from other sources will be addressed
after investigations of other potential sites in the area are concluded. The
remedy is expected to attain action-specific ARARs, which included Resource
Conservation and Recovery Act (RCRA) capping requirements; RCRA Land Disposal
215

Restrictions; and Clean Water Act (CWA) requirements for discharges to publicly-
owned treatment works. The selected remedy was discussed with the State of
Maryland and City of Baltimore.

PALMERTON ZINC SITE
BLUE MOUNTAIN OPERABLE UNIT
PALMERTON, PENNSYLVANIA
HRS Score: 42.93 NPL Rank: 306
Background
The Palmerton Zinc site, location of the New Jersey Zinc Company smelter,
is in the vicinity of Palmerton, Pennsylvania, approximately 70 miles north of
Philadelphia. Smelting operations have occurred since 1898 at two separate
locations, the west smelter and the east smelter. Until December 1980, primary
smelting of concentrated zinc sulfide ores caused emissions of huge quantities
of zinc, lead, cadmium, and sulfur dioxide that led to the defoliation of
approximately 2,000 acres on Blue Mountain, which is adjacent to the east
smelter.
The Superfund investigation of the Palmerton Zinc site focused on three
problem areas: (1) the deposition of heavy metals throughout the valley as a
result of air emissions from the smelter; (2) the slag pile, approximately 2.5
miles long, consisting of an estimated 33 million tons of smelting waste; and
(3) the defoliation of Blue Mountain. The EPA lead remedial
investigation/feasibility study (RI/FS), completed in April 1987, focused on the
defoliated sections of Blue Mountain. Under a Consent Order signed in September
1985, Gulf and Western, Inc. and Horsehead Industries, Inc., past and current
owners of the smelter, are conducting RI/FSs for the other two problem areas.
EPA gave these potentially responsible parties notice of their potential
liability for the implementation of the Blue Mountain operable unit remedial
action. The ROD for this operable unit was signed September 4, 1987.
Description of Site Work
The EPA lead RI for the Blue Mountain operable unit indicated that surface
soils at the site were heavily contaminated with cadmium (from a range of 264
to 1,300 ppm) , lead (1,200 to 6,475 ppm) , and zinc (13,000 to 35,000 ppm) .
Because the metals were bound in organic materials, most of the metal
contamination was contained within the top 6 to 10 inches of soil.
Water flowing across the defoliated portions of Blue Mountain has eroded
the surface, become contaminated with metals contained in the soil, and carried
the metal-laden soil into a nearby creek. Sampling performed by Horsehead
Industries in March 1986, under the consent agreement with EPA, indicated that
the runoff exceeds EPA's ambient water quality criteria; in some instances, the
levels are 20 times as great. The environmental impacts of the metal
contamination include defoliated vegetation; erosion; the absence of microflora,
lichens, arthropods, and wildlife species; and heavy metal contamination of
fish.
217
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
The RI/FS report, completed in April 1987, listed the following as major
objectives of remedial actions to be taken at the site: (1) minimization of
direct contact with contaminated soil; (2) reduction of the volume of runoff;
(3) reduction of contamination in runoff; and (4) mitigation of environmental
damage. Based on these objectives, source control and mitigation control
technologies were developed and screened. Technologies involving treatment were
eliminated in this initial screening due to their high cost, poor performance,
unreliability, or non-implementability. One alternative, collecting and
treating runoff, was deferred for further study in a subsequent RI/FS.
Technologies retained for further analysis were the following:
(1) No action;
(2) Deed restrictions only - prohibition of residential
development and agricultural use of defoliated portions
of Blue Mountain; and
(3) Soil amendments and revegetation with deed restrictions
- using a mixture of sewage sludge and fly ash to
revegetate defoliated areas.
Applicable or relevant and appropriate requirements (ARARs) identified for
this site included: Clean Water Act (CWA) Best Management Practices dealing
with surface-water discharges, and State of Pennsylvania Department of
Environmental Resources (DER) "Interim Guidelines for Sewage Use for Land
Reclamation." The DER guidance includes guidelines for maximum loading rates
for metals, maximum dry sludge application, soil acidity adjustment, and other
sludge application guidelines.
The community of Palmerton expressed concern about the potential health
effects of the soil and ground-water contamination at the site, and also about
the financial impact on the zinc company. Many of their concerns can be
addressed only when further remedial action for other operable units is taken.
Description of Selected Remedy
The selected remedy for the site includes using sewage sludge and fly ash
cover to revegetate defoliated areas. This is an interim remedy that will be
consistent with the final comprehensive remedy for the site. When the RI/FSs
for the other operable units are completed, RODs will be issued to address all
aspects of the site.
The ROD indicates that although the remedy does not attempt to ensure
compliance with all ARARs for the entire site, it will be consistent, to the
extent practicable, with those action-specific ARARs addressing sludge
application and the CWA Best Management Practice requirements. The rocky
terrain of Blue Mountain precludes compliance with some Pennsylvania DER sludge
application guidelines.

PRESQUE ISLE SITE
ERIE, PENNSYLVANIA
HRS Score: 40.59 NPL Rank: 376
Background
The Presque Isle site is located on the Presque Isle State Park peninsula
within the City of Erie, Pennsylvania, and includes an abandoned natural gas
well and its surrounding contaminated area. The well, known as Presque Isle
Beach No. 7 well, intercepts a geologic formation known as the Bass Island
Formation. In 1982, the well was revealed to be the source of a discharge of
noxious, hydrogen-bearing black liquid that had been observed since the early
1970s. The Pennsylvania Department of Environmental Resources (DER) permanently
capped the well in October 1982, and determined at that time that previous
seepage did not present any health hazards. Presque Isle was included on the
NPL, however, because of concerns that the same fluid might be seeping from
other abandoned gas wells, of similar age and construction, in the area.
Subsequent investigations revealed that the discharge released hydrogen
sulfide into the atmosphere and other hazardous substances into the soil and
shallow ground water. EPA and DER investigations of the source discharge
focused on whether the discharge was a natural phenomenon, or if it was related
to the deep-well injection by Hammermill Paper Company of approximately 1.1
billion gallons of spent pulping liquor into the Bass Island Formation between
1964 and 1971. Currently, Hammermill is the only waste generator that could be
linked to the site as a potentially responsible party (PRP). However, the
injection of pulping wastes has not been conclusively linked to the discharge
at the Beach No.7 well. Hammermill contends that the discharge was a natural
fluid. Even if the fluid was identified as resulting from the pulping wastes,
Hammermill argues, it would be exempted from CERCLA because it was from a State-
permitted disposal operation.
The EPA lead remedial investigation/feasibility study (RI/FS) was completed
in October 1985, and the ROD for the site was signed September 30, 1987.
Description of Site Work
Results from the EPA lead RI suggested that the chemical data concerning
the initial source of the discharge is ambiguous, and the resolution of these
ambiguities at this time is impossible. The most probable conclusion of the RI
is that the injection program forced a possibly naturally occurring fluid near
the surface to seep from the Beach No.7 well.
Investigations determined that the discharge at the well was an unusual
event, and that the threat to the public was eliminated when access to the Bass
Island Formation from this well was permanently plugged in 1982. As a result,
the only known source of the seepage has been capped. Since that time, there
have been no confirmed releases of hydrogen sulfide gas. No migration pathways
have been recognized, and based on a July 1987 DER sampling, no significant
contamination is present at or adjacent to the Beach No. 7 well.
219
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
According to the EPA lead FS, the major remedial action objectives at the
Presque Isle site included: (1) prevention/minimization of direct human
exposure to gaseous and liquid wastes from uncontrolled discharges and (2)
prevention/minimization of potential contamination of surface and ground water
by pressure flow through fractures, gas and oil wells, or other pathways. Based
upon these objectives and site-specific conditions, the following alternatives
were developed and evaluated:
(1) Depressurization of Bass Island Formation;
(2) Installation of monitoring wells in Bass Island
Formation to determine seepage origin;
(3) Installation of monitoring wells in Bass Island
Formation to predict the potential migration pathway
of Hammermill's injected waste; and
(4) No action;
The ROD did not discuss the existence of any applicable or relevant and
appropriate requirements (ARARs) for the site, nor did it discuss CERCLA
statutory preferences for permanent treatment-based remedies.
Currently, there is only a moderate level of community awareness about the
Presque Isle site. At a public meeting held in August 1987 to discuss the RI/FS
and EPA1s recommended alternative, a local environmental group representative
maintained that the decision was premature, because studies performed may not
be sufficient to ascertain the extent of hazard posed by the site now, and
because a natural phenomenon such as an earthquake could cause another seepage
incident.
Description of Selected Remedy
Based on the RI findings that the site currently presents no threat to the
public and that no significant contamination is present, EPA selected "no
action" as the remedy for this site. The high cost and great difficulty of
performing the other remedial alternatives were also factors in this selection.
However, EPA and DER made a number of recommendations for activities outside the
scope of the ROD that Pennsylvania State agencies should implement to minimize
further problems or releases associated with natural formation brines in the
area.

SALTVILLE WASTE DISPOSAL SITE
SALTVILLE, VIRGINIA
MRS Score: 29.52 NPL Rank: 737
Background
The Saltville Waste Disposal Site is located in southwestern Virginia
between the towns of Saltville and Allison Gap, along the North Fork of the
Holston River (NFHR). From 1951 to 1972, the Olin Corporation operated an
electrolytic chlorine and caustic soda plant at the Saltville site that
manufactured chlorine gas and sodium hydroxide. One of the electrodes used in
the chlorine-caustic process contained mercury that was solubilized and passed
into a waste pond in the sludge and brine. Additional mercury was lost as a
result of sloppy operating procedures.
An investigation revealed the presence of severe mercury contamination, and
both Virginia and Tennessee banned fishing in the NFHR. Mercury losses were
estimated by Olin to be 100 pounds per day between 1951 and 1970. After this
discovery, however, Olin modified its procedures to cut mercury losses to 1/4
pound per day.
In 1970, the Virginia State Water Control Board (SWCB) adopted a Total
Dissolved Solids Standard of 500 mg/1 for the river, which Olin was not able to
meet. As a result of this, as well as increased operating costs, Olin closed
its Saltville operations in 1972. Annual sampling of fish and sediment in the
NFHR since 1970 has indicated mercury contamination in the sediments and surface
water near the site and in the tissues of fish up to 80 miles downstream from
the site.
The site was listed on the proposed NPL in December 1982, and the SWCB
issued a Consent Order to the Olin Corporation that required Olin to take
certain remedial measures. Under the Consent Order, the Olin Corporation
dredged the river bed, extracted mercury, spread the sediments over the plant
site, and constructed a cap. Additionally, Olin has continued fish and sediment
sampling to monitor the extent of mercury contamination. The ROD was signed
June 30, 1987.
Description of Site Work
A remedial investigation (RI) was not performed at this site because of the
availability of data and ongoing sampling effort being conducted by Olin under
the Consent Order. Instead, a risk assessment (RA) was conducted using
available data to determine if data gaps existed. Several data gaps were
identified in the RA.
The contaminant of concern at the site is mercury seeping into the NFHR
from the waste pond outfall. Mercury accumulates in fish and other organisms;
its effects become more widespread as it is carried up the food chain. The
NFHR, like other rivers in the area, supports a relatively diverse population
of freshwater mollusks, including species of endangered mussels.
221
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
The EPA and the State of Virginia initiated a feasibility study (FS) in
1986 and identified several remedial alternatives that would reduce the mercury
concentration in the NFHR. However, due to the inadequacy of data, the Fish and
Wildlife Service and EPA decided that a complete bioassessment of potential
effects on the area's environment is necessary to develop remedial actions.
Thus, the FS was used to develop interim remedies only.
Alternatives identified in the FS were separated into two categories: (1)
source controls; and (2) management of contaminant migration in the river.
After screening, four treatment alternatives were considered in detail:
(1) No action;
(2) Upgrading run-on controls with ditches, berms, and
downchutes;
(3) Upgrading run-on controls, treating pond outfall, and
installing ground-water monitoring systems; and
(4) Upgrading run-on controls, capping ponds, arid
installing ground-water monitoring systems.
Several applicable or relevant and appropriate requirements (ARARs) were
considered during the FS process: Resource Conservation and Recovery Act (RCRA)
Subtitle C, Clean Water Act (CWA), Virginia State Water Control Laws and
Regulations, Floodplains and Wetlands Executive Order and Guidance, and Fish and
Wildlife Coordination Act requirements.
Despite the ban on fishing, community interest during the RI/FS process was
low and no public meeting was requested during the comment period. Most
comments on the FS were received from the States of Virginia and Tennessee and
from the Olin Corporation.
Description of Selected Remedy
The selected alternative for the Saltville site consists of upgradient
storm-water control by constructing ditches, berms, and downchutes; treatment
of pond outfall; and ground-water monitoring (Alternative 3). The recommended
alternative is an interim measure because additional studies are needed to
determine the extent of contamination. These studies will include a ground-
water study, a bioassessment, and the implementation of additional sampling
along the NFHR. Once these studies are complete, a final remedial solution will
be developed.

WEST VIRGINIA ORDNANCE WORKS
FIRST OPERABLE UNIT
MASON COUNTY, WEST VIRGINIA
MRS Score: 35.72 NPL Rank: 89
Background
The West Virginia Ordnance Works (WVOW) site covers 8,323 acres along the
east bank of the Ohio River, 58 miles northwest of Charleston. One-third of
this area is occupied by the McClintic Wildlife Station, a fish and migratory
waterfowl management area. From 1942 to 1945, the site was used by the Federal
government to produce trinitrotoluene (TNT) explosives. Operations ceased in
1945, and the land was deeded to West Virginia on the condition that the site
be used for wildlife management. Subsequent limited industrial activity at the
WVOW site may have contributed to the environmental contamination.
In May 1981, the West Virginia Department of Natural Resources (DNR) and
EPA identified the release of TNT processing wastes into a pond in the wildlife
area. Based on subsequent studies by EPA and the DNR, WVOW was placed on the
NPL. Hydrogeologic investigations indicated the potential for migration of
contaminants via surface- or ground-water pathways to deeper levels of the
aquifer or to the Ohio River. Nitro-aromatic residues and other TNT
manufacturing byproducts presented the most serious carcinogenic and migratory
threat. In January 1986, the Department of Defense (DOD) and EPA agreed to
divide projected site work into two geographically separate operable units.
Remedial efforts for the first operable unit, the TNT Manufacturing Area,
Burning Grounds, and Industrial Sewerlines, were initiated, as additional data
were gathered for the second operable unit. The ROD for the first operable unit
was signed March 31, 1987.
Description of Site Work
The remedial investigation (RI) for the first operable unit was completed
in March 1986. The RI indicated that the major sources of nitro-aromatic
contamination were: (1) surface and subsurface soils in the TNT and Burning
Grounds areas; and (2) the industrial sewerlines in the TNT area. Contaminants
in the TNT and Burning Ground areas included residual nitro-aromatic compounds
and contaminated soils. Nitro-aromatic compounds were also observed in the
ground water in the shallow aquifer and in surface water in the TNT area.
However, no nitro-aromatic compounds were detected in ground water from supply
wells near the wildlife station. Residences will not be constructed in the area
nor will the ground water beneath the site be used for drinking.
The endangerment assessment concluded that although contaminants presented the
threat of direct and indirect exposure, the restrictive nature of the wildlife
station reduced the actual risk to human health. Potential risks to human
health were posed by consumption of contaminated wildlife at the site and by
reactive substances in sewerlines.
223
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
The feasibility study (FS) for the first operable unit was completed in
October 1986. The primary objectives were that the selected remedy eliminate
the safety hazards of reactive wastes and stabilize the cancer risk for hunters
and visitors in the wildlife station. For each area to be addressed in the
first operable unit, a variety of remedial alternatives were proposed,
including: multimedia capping, off-site and on-site incineration of
contaminants, off-site and on-site landfilling, placement of a soil cover, and
no action.
Use of any of the above technologies would require compliance with Federal
and State applicable or relevant and appropriate requirements (ARARs). Federal
regulations that are potential ARARs included Resource Conservation and Recovery
Act (RCRA) disposal requirements, National Ambient Air Quality Standards
(NAAQS), transportation requirements, and Federal Water Quality Criteria (WQC).
State ARARs included water quality standards, waste disposal regulations, and
wetlands regulations.
Members of the public residing near the site have shown interest in its
status since 1984, primarily because of contaminated ground water. Public
meetings were held in February and in November 1986 to discuss the RI and the
FS, respectively. The fact that oral comments were in support of the remedy,
and that no written comments were received at the November meeting, suggested
there was little objection to the chosen remedial alternative.
Description of Selected Remedy
EPA recommended a four-part remedial approach for the WVOW site:
• In situ flaming of reactive TNT residues in the Burning
Grounds Area and installation of soil cover over areas
with high nitro-aromatics contamination;
• Installation of soil cover over contamination in the
TNT Manufacturing Area;
• Disposal of asbestos found in the Burning Grounds Area ;
and
• Flushing and backfilling of reactive sewerline with
installation of soil cover in areas of high
contamination.
EPA found this remedial approach to be the least costly alternative that
also protects against direct contact and minimizes exposure pathways. The
technologies involved in the preferred remedy are acceptable and proven; no
alternative offers a significant technical advantage. The preferred remedy does
require long-term care to maintain the integrity of the soil cover.

GOLD COAST OIL CORPORATION SITE
MIAMI, FLORIDA
HRS Score: 57.80 NPL Rank: 67
Background
The Gold Coast Oil Corporation (GCO) site is a 2-acre parcel of land
located in Miami, Florida. The owner of the property, CSX Transportation,
leased it to GCO which, along with Solvent Extraction Incorporated, used the
site as a solvent reclamation facility during the 1970s. The site is within a
commercial, industrial, and residential area having a population greater than
80,000 within a 3-mile radius. The Biscayne Aquifer, which underlies a portion
of the site, is the only ground-water source of drinking water in southeastern
Florida.
During facility operations, the companies sprayed residue directly onto the
ground and stored 53 drums of sludge-contaminated soil on site. There were also
2,500 corroded and leaking drums on site containing sludge from the distilling
operation, contaminated soils, and paint sludges. All wastes generated by the
solvent recovery operations were disposed of or stored on site.
In 1980, the Dade County Department of Environmental Resource Management
(DERM) sampled the illegally dumped and stored wastes. During 1981 and 1982,
the State, DERM, and EPA sought to remedy conditions at the site through various
enforcement actions against the facility, its operator, and the site owner.
When these actions failed, EPA initiated an investigation to determine if a
CERCLA response was necessary. In 1982, in response to potential Federal
enforcement and cleanup actions, CSX evicted GCO and agreed to clean up the
surface of the site voluntarily. Two major sampling efforts were performed
after the voluntary cleanup, and it was determined that the soil and ground
water were still extremely contaminated.
EPA added the Gold Coast Oil site to the NPL in March 1983. EPA identified
a number of potentially responsible parties (PRPs). In addition to the cleanup
by CSX, generators of waste stored at the site joined together to perform the
remedial investigation (RI). The RI was reviewed by EPA and the State, and EPA
followed with the feasibility study (FS), completed in 1984. EPA conducted an
endangerment assessment in late 1986, and the ROD for the site was signed
September 11, 1987. Currently, negotiations with the identified PRPs for
performance of the selected remedial action are ongoing. A settlement is
expected by June 1988.
Description of Site Work
The RI performed by the generators in 1983 and additional studies by EPA
and DERM indicated that soil and ground water were contaminated with organic
compounds and heavy metals. The studies identified leaching of contaminants
from surface and subsurface soils to the ground water and migration of
contaminated ground water to surface water as the primary pathways of concern.
The general contaminants of concern were halogenated solvents, non-halogenated
solvents, still bottoms from the recovery of these solvents, and heavy metals.
Analysis of surface soil in 1983 indicated that the distilling and drum storage
225
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
areas were contaminated with chlorobenzene, 4-nitrophenol, toluene, and di-
phthalate. The 1986 sampling indicated residual surface contamination. The
1986 analysis of subsurface soil samples revealed high levels of toluene, ethyl
benzene, xylene, styrene, and bis(2-ethyl hexyl) phthalate, although levels were
lower than in 1983. Ground-water data indicated an area of significant
trichloroethylene and tetrachloroethylene contamination in the northeast corner
of the site. Concentrations of metals in ground water decreased between the
1983 and 1986 samplings, but organics were still present in 1986.
Description of Feasibility Study
The objective of the FS was to identify a remedy(ies) that would (1)
eliminate the risk of exposure from contaminated soils and (2) remediate
contaminated drinking-water sources before the plume migrated further and
contaminated more of the Biscayne Aquifer. EPA developed and evaluated
technologies that addressed source control and ground-water contamination. The
alternatives that passed the initial screening were:
(1) No action;
(2) Air stripping of soils and ground-water recovery,
treatment, and disposal;
(3) Steam stripping of soils and ground-water recovery,
treatment, and disposal;
(4) On-site incineration of soils and ground-water
recovery, treatment, and disposal;
(5) Stabilization/solidification of soils and ground-water
recovery, treatment, and disposal;
(6) Off-site incineration of soils and ground-water
recovery, treatment, and disposal; and
(7) Off-site disposal of soils and ground-water recovery,
treatment, and disposal.
Each remedial alternative was screened against the CERC1A criteria of
effectiveness, implementability, protectiveness, and cost. The applicable or
relevant and appropriate requirements (ARARs) identified for the site were the
National Environmental Protection Act (NEPA), Department of Transportation (DOT)
Hazardous Material Transport Rules, Resource Conservation and Recovery Act
(RCRA) land disposal ban, Clean Air Act (CAA) National Ambient Air Quality
Standards (NAAQS), Safe Drinking Water Act (SDWA) Maximum Contaminant Levels
(MCLs), Clean Water Act (CWA) pretreatment and discharge standards, and Florida
Administrative Code Chapter 17-3 Water Quality Standards.
Although citizen interest in the Miami area in water quality is very high,
community involvement in the Gold Coast site was limited. EPA held one public
meeting, but the majority of those in attendance were representatives of the
226
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
PRPs. EPA also published newsletters with current information on the site. No
public comments were received during the formal FS comment period.
Description of Selected Remedy
The remedial action alternative recommended for the site included
excavation of contaminated soils with off-site disposal of hazardous waste
sludges at an approved RCRA facility, and stabilization/solidification of the
remaining contaminated soils (Alternative 7) . To address the contamination
found in the ground water beneath the site, the recommended alternative also
included installation of a recovery well field, treatment of recovered ground
water, and disposal of treatment residues. EPA has not yet selected the ground-
water treatment method.
The chosen alternative uses treatment technologies to the maximum extent
practicable, employs a permanent solution that reduces the toxicity and mobility
of the contamination, and is protective of human health and the environment.
EPA also expects the remedy to attain ARARs.

NORTHWEST 58th STREET LANDFILL SITE
BISCAYNE AQUIFER FINAL OPERABLE UNIT
DADE COUNTY, FLORIDA
HRS Score: 49.43 NPL Rank: 181
Background
The Northwest (NW) 58th Street Landfill site is located in northwest Dade
County, Florida. From 1952 to 1982, the one-square mile site was operated as
an open dump. Although it was not operated as a hazardous waste landfill, it
likely received some hazardous waste. Some early wastes were disposed of in
shallow trenches, resulting in waste deposits in the saturated zone of the
Biscayne Aquifer, which underlies the site. The aquifer is the sole source of
drinking water for the Miami/Dade County area.
The site was placed on the NPL in 1981, and in October 1982, EPA ordered
the county to cease accepting municipal wastes. The site is one of three NPL
sites that affect the same general area of the Biscayne Aquifer. The other two
sites are Miami .Drum Services and Miami International Airport. Because the
effects of these sites on the aquifer are interrelated, remedial activities at
the sites are being addressed collectively. EPA completed the remedial
investigation/feasibility study (RI/FS) for the Biscayne Aquifer study area in
1984.
A total of four operable units will be completed as part of the complete
remedy under the Biscayne Aquifer Study. The first operable unit involved soil
and ground-water cleanup at the Miami Drum Services site, and a ROD for source
control was signed in September 1982. A ROD for the second operable unit, the
Varsol spill at the Miami Airport, was signed in March 1985 and required no
action. The ROD for the third operable unit, the Study Area Ground-Water
operable unit, was signed in September 1985 and called for air stripping in the
existing ground-water treatment process. The final operable unit addressed
source control at the NW 58th Street Landfill and provision of alternative water
supply. The ROD for the landfill site operable unit was signed September 21,
1987.
Description of Site Work
Numerous investigations have been conducted at the landfill site, including
the efforts conducted as part of the Biscayne Aquifer RI/FS. Investigations at
this site concentrated on determining the magnitude and extent of ground-water
contamination resulting from the landfill. A study by the U.S. Geological
Survey indicated the presence of a plume of contamination migrating downgradient
from the landfill. The results of the RI indicated that widespread low to
moderate levels of several toxic contaminants, primarily VOCs, were present in
the ground water.
An endangerment assessment in 1986 found eight contaminants of concern in
the monitoring wells both upgradient and downgradient of the site: arsenic,
chromium, zinc, benzene, chlorobenzene, 1,1,2,2-tetrachloroethane,
trichloroethene, and vinyl chloride. The primary route of human exposure to the
228
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
contamination is through ingestion of contaminated water. Of particular concern
are two sets of public drinking water supply well fields located within 2.5
miles of the site. The population served by the well fields is estimated to be
about 750,000.
Description of Feasibility Study
The FS for the landfill operable unit focused on identifying remedies to:
(1) reduce on-site soil contamination; (2) reduce site-related ground-water
contamination; and (3) protect downgradient private well users. The FS
considered several alternatives applicable to the landfill site:
(1) No action;
(2) Installation of on-site recovery wells and treatment
of ground water prior to discharge;
(3) Installation of on-site recovery wells and deep
injection well disposal of recovered ground water;
(4) Containment of contaminants;
(5) Excavation of the landfill; and
(6) Implementation of leachate control measures.
Possible remedies were screened with respect to practicability,
implementability, and cost; CERCLA criteria for employing permanent solutions
and treatment technologies to the maximum extent practicable; and ability to
attain applicable or relevant and appropriate requirements (ARARs). ARARs
identified for the site include the Safe Drinking Water Act (SDWA), Clean Water
Act (CWA), Resource Conservation and Recovery Act (RCRA) Subtitle D landfill
closure requirements, and Florida Administrative Code (FAC) requirements for
resource recovery and management, permitting, water quality, storm water
discharge, and underground injection control.
In July 1984, a community relations plan was completed for the Biscayne
Aquifer area. Under this plan, EPA convened four public meetings, held
workshops on issues of special interest, and printed and distributed a
newsletter. Expressed public interest focused on closure of the landfill.
Description of Selected Remedy
The selected alternative consisted of closing the NW 58th Street Landfill
in accordance with the technical requirements of the State regulations,
providing municipal water to private well users, and collecting the water and
treating it by air strippers at municipal treatment plants. Closure activities
will include leachate control through a combination of grading, drainage
control, and capping. Gas migration and odor controls also will be implemented
as needed, as will long-term monitoring of ground-water quality and operation
and maintenance of the closure.
229
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
The selected remedy will reduce the amount of leachate produced and its
mobility, but will not reduce toxicity. Alternatives involving treatment were
judged to be impracticable and not cost-effective due to the magnitude of waste
to be treated (approximately 27 million cubic yards). The remedy does provide
for long-term protection of the ground water and public health. The remedy is
expected to attain ARARs.

PARRAMORE SURPLUS COMPANY SITE
MT. PLEASANT, FLORIDA
MRS Score: 37.61 NPL Rank: 455
Background
The Parraraore Surplus Company site is located in Mt. Pleasant, Florida,
approximately 30 miles from Tallahassee. The 25-acre site is an active facility
which stores and resells surplus government products. The population within a
one-mile radius of the site numbers less than 100 and the land adjacent to the
site is used primarily for agriculture.
In 1972, drums of paint residue, waste oil, alcohols, and degreasers were
purchased and stored on the site. In 1982, the Florida Department of
Environmental Regulation (FDER) discovered that many of the 400 to 600 drums
were leaking contaminants, thus causing damage to the site vegetation. EPA's
analysis of samples collected from the site indicated PCB contamination in the
soil. The site was placed on the NPL at the request of FDER. In August 1982,
FDER notified the facility that it was in violation of Florida Administrative
Code requirements concerning hazardous waste storage facilities. The owner of
the Parramore Surplus facility, Mr. Houston Parramore, was identified as the
primary potentially responsible party (PRP). Following a meeting with FDER and
EPA, Parramore removed the leaking drums and contaminated soil and shipped them
to an approved hazardous waste disposal facility. Parramore also constructed
a fence around the site and posted warning signs. In July of 1983, additional
areas of contamination were discovered and Parramore was requested to excavate
and contain these areas. In October 1983, FDER conducted an inspection of the
site and found that all conditions of the site cleanup had been met.
EPA conducted a modified remedial investigation (RI) of the site in March
1985 and completed a public health evaluation (PHE) in 1987 to determine whether
further soil remediation was necessary to protect human health. No feasibility
study (FS) was conducted because results of the PHE indicated that residual
levels of soil contamination posed no substantial threat to human health or the
environment. The ROD was signed September 15, 1987.
Description of Site Work
The EPA lead modified RI included soil sampling and installation of
temporary ground-water monitoring well-points. Results of the modified RI
indicated the presence of soil contamination on site. Results of ground-water
samples were considered inaccurate because the ground water contained large
amounts of suspended sediments. The possibility of ground-water contamination,
however, was considered unlikely because of the shallowness of the soil
contamination and the limited area to which it was confined.
The modified RI detected eight contaminants of concern at the site: lead,
zinc, cyanide, Bis(2-ethylhexyl) phthalate, di-n-butyl phthalate, ethylbenzene,
methyl ethyl ketone, and PCB-1254. Those at highest risk from exposure to on-
site contamination, through inhalation or ingestion, included Parramore Surplus
Company employees and wildlife that feed on site vegetation. The PHE, which was
completed after the contaminated soil was removed, detected lead, zinc, and PCB-
231
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
1254 but at such low levels that they did not pose a threat to human health or
the environment. Based on the PHE, therefore, it was concluded that no further
remediation of the soil was necessary.
Description of Feasibility Study
EPA did not complete an FS of alternative remedial actions at the Parramore
site because no need for further remedial action was indicated by the PHE.
Applicable or relevant and appropriate Federal and State requirements (ARARs)
included the Toxic Substances Control Act (TSCA), Federal and State drinking
water standards, and monitoring well installation and construction rules under
the Florida Administrative Code.
EPA established an information repository at a public library near the site
in July 1987 and published notices of the proposed remedial action plan and
requests for public comment. The public was also invited to request a public
meeting with EPA to discuss the site and the remedial action plan. No comments
or requests for a public meeting were received and no public opposition to the
recommended action is expected.
Description of Selected Remedy
No further remedial action is planned at the Parramore Surplus Company
site. A ground-water quality assessment will be conducted to ensure that local
drinking water supplies have not been adversely affected by hazardous substances
on site. If ground-water contaminant levels exceed standards contained in
ARARs, a complete ground-water investigation will be done.

Background
The Tri-City Oil Conservationist Corporation site, a 1/4 acre property
located in Temple Terrace, Florida, 5 miles north of Tampa, was used as a waste
oil collection and distribution center from 1978 to 1983. Operating conditions
during this time led to spills during transfer operations, leaks from tanks and
liners, and accumulation of liquid wastes at the site. The Florida Department
of Environmental Regulation (FDER) received several public complaints regarding
odor problems and "sloppy" practices.
In 1982, a 3,000 gallon waste oil spill occurred. FDER subsequently
analyzed soil and sludge from the site and discovered hydrocarbons and heavy
metals such as lead, chromium, and zinc. Additional sampling in 1984 revealed
high concentrations of benzene, toluene, xylene, and chlorinated hydrocarbons
in soils as deep as 1 to 2 feet below the surface. Contaminated soils posed an
environmental threat both to ground and surface waters because of migration from
the source area to potential water supplies. Both human and animal populations
use the surface waters near the site (such as the Hillsborough River, located
3,000 feet from the site) as drinking water supplies. In addition, eight
private drinking water wells are located within 1/4 mile of the site.
Prior to the remedial investigation/feasibility study (RI/FS), both EPA
and FDER conducted removal actions. The ROD for the site was signed September
11, 1987. A potentially responsible party search report identified several
owner/operators and generators who were potentially responsible parties (PRPs).
One PRP, Tri-City Oil Conservationist Corporation, was dissolved involuntarily
on November 10, 1983, and other owner/operator PRPs are bankrupt. EPA has not
yet initiated a cost-recovery action against the PRPs for the $50,000 spent in
a removal action in February 1984, although it may do so in the future. The
State of Florida currently is pursuing a civil cost-recovery action against the
owner/operators of the site for the $200,000 spent for its contamination
assessment and subsequent removal action.
Description of Site Work
In response to the substantial endangerment to human health and the
environment, EPA conducted an immediate removal of contaminated waste oils,
sludges and contaminated soils in 1984. Because no follow-up sampling was done
immediately after this removal, the FDER assessed the remaining contamination
later that year. The assessment revealed that VOCs and heavy metals still
contaminated the top 1 to 3 feet of soil on the site.
Based on this assessment, FDER initiated a removal effort that reduced
contamination to background levels. This involved the removal of 850 cubic
yards of contaminated soil, removal of two above-ground storage tanks,
excavation of a 16,000 gallon underground storage tank, and removal of 5,000
gallons of organic liquids and sludges. When excavation was completed, clean
233
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
fill was used to bring the site back to its original grade. This action was
completed in May 1985. FDER conducted follow-up ground-water sampling in late
1985 and the first half of 1986.
Upon review of the data generated by the FDER in its sampling efforts, as
well as of other data, it was determined that the Tri-City site no longer was
contaminated. All of the contaminated soil and sludges have been removed to an
EPA-approved hazardous waste facility, and 1986 sampling indicated that no
ground-water contaminants exceeded drinking water standards.
Description of Feasibility Study
The EPA lead RI/FS identified the following technologies for addressing the
site contamination: thermal destruction, capping, aeration, solidification/
stabilization, and surface soil/sediment removal. Applicable or relevant and
appropriate requirements (ARARs) identified for the site included the following:
Florida drinking and surface-water standards, the Safe Drinking Water Act
(SDWA), EPA Ground-Water Protection Strategy, and the Clean Water Act (CWA).
However, because it appeared that the site no longer posed a health-related or
environmental threat, an evaluation of various technologies and their
effectiveness, applicability, and consistency with ARARs was found to be
unnecessary.
No extensive community relations activities have been conducted for the
site due to the lack of interest expressed by the local community. Both EPA and
FDER have received only one inquiry and no complaints since the public notice
outlining EPA's proposed plan for further activities was issued in August 1987.
Description of Selected Remedy
Under the "no action" alternative selected for this site, no additional
remedial actions will be performed. Because all contaminated soils have been
removed and no significant contamination reached ground-water supplies in the
area, additional remedial activities are not necessary.
The ROD indicated that the remedy selected was considered to be the most
effective alternative in terms of removing the threats posed by the site, given
both the clean-up technologies available and the size of the site. Given the
small .volume of contaminated materials, the "no action" remedy utilizes
permanent treatment technologies to the maximum extent practicable. EPA
concurred with the past remedial actions conducted by the State of Florida, and
the State concurred with the "no action" final remedy chosen by EPA for the
site.

TOWER CHEMICAL COMPANY SITE
CLERMONT, FLORIDA
MRS Score: 44.03 NPL Rank: 286
Background
The Tower Chemical Company site is located 15 miles west of Orlando,
Florida, along the eastern edge of Lake County. From 1957 to 1981, the Tower
Chemical Company manufactured, formulated, and stored pesticides at the site.
The main facility included a burn/burial area for solid wastes and a
percolation/evaporation pond for acidic wastewaters. A spray irrigation field
consisted of four parallel strips of land.
Some of the chemicals manufactured at the facility required the use of
dichlorobenzil in the production process. During the last few months of the
company's operation, dichlorobenzil was manufactured in-house using dichloro-
diphenyl-trichloroethane (DDT). Acidic wastewaters from this manufacturing
process were discharged into the unlined percolation/evaporation pond located
at the main facility. In July 1980, the pond overflowed and the spray
irrigation field was then used to discharge acidic wastewaters.
As a result of the overflow, both EPA and the Florida Department of
Environmental Regulation (FDER) initiated studies of the Tower site and the
nearby lake and stream. All production was stopped at the facility in December
1980, and the facility was subsequently decommissioned. The studies indicated
high concentrations of DDT and associated pesticide compounds in the main
facility waste disposal areas, stream, and ground water. Soils at the spray
irrigation field were contaminated by pesticides, primarily within the top foot
of soil.
The Tower site was listed on the NPL in December 1982. A remedial
investigation/feasibility study (RI/FS) was initiated in March 1984 and the ROD
was signed June 30, 1987. Although several potentially responsible parties were
identified, none have made a proposal to undertake any response actions.
Description of Site Work
The EPA initiated the RI/FS after it conducted an immediate removal measure
(IRM) at the site. During the IRM, the burn/burial area was excavated and
covered with a clay cap, and water from the percolation/evaporation pond was
pumped, treated, and discharged. The contaminated sediments from the pond were
excavated, dewatered, and disposed off site. Although the FDER conducted an IRM
at the spray irrigation field, this area was addressed in the RI/FS.
The RI was conducted 8 months after the IRM, and revealed that only a small
volume of soils (approximately 4,000 cubic feet) in the main facility area still
exceeded the cleanup criteria. The RI also showed that no contamination existed
within the spray irrigation field in excess of the established soil cleanup
criteria that were jointly established for the site by EPA and FDER. The
results of ground-water sampling and analysis at the main facility revealed that
the surficial aquifer, which flows northeast toward the unnamed creek, was
235
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
contaminated with xylene, ethyl benzene, gamma-BHC, chlorobenzilate, 4,4'-DDT
with its derivatives, and several other compounds. Contaminant migration had
extended beyond the boundaries of the burn/burial area, with possible
contaminated ground-water discharge occurring into the ditch east of the
facility. Vertically, contaminated ground water in the burn/burial area was
identified at a depth of 35 feet.
Description of Feasibility Study
During the feasibility study (FS) process, potential remedial technologies
were presented in groups targeted at remediating a single aspect of the site,
either surface- and ground-water contamination, soil contamination, or
institutional controls. These remedial units then were combined to develop full
remedial alternatives that would be applied to the conditions existing at the
Tower site. After screening, eight comprehensive remedial alternatives
remained, including the "no action" alternative. The other seven alternatives
included ground-water and surface-water monitoring and various combinations of
the following:
• Municipal water supply extension;
• Individual treatment units;
• Tanks and concrete pad removal;
• Point source runoff diversion;
• Capping;
• Surface regrading and revegetation;
• Surface soil/sediment removal;
• Ground-water removal;
• Excavation;
• Water treatment technologies;
• Soil incineration; and
• Off-site disposal.
Several combinations of technologies resulted in remedial actions that
comply with applicable or relevant and appropriate requirements (ARARs). ARARs
considered in the FS included the Safe Drinking Water Act (SDWA), Clean Water
Act (CWA), the Resource Conservation and Recovery Act (RCRA), and Florida
regulations for surface water, drinking water, and hazardous waste.
Community interest in the Tower site has been limited, although area
residents did express concern about both health and non-health issues. Findings
of the RI/FS were discussed at the public meeting in October, 1986 that served
to initiate a 3-week public comment period.
Description of Selected Remedy
The alternative recommended for the Tower Chemical site consisted of
removal and treatment of contaminated ground water; provision of individual
treatment units for two private wells in the immediate site vicinity; removal
and thermal treatment of contaminated surface soils from both the overflow and
portions of the burn/burial area of the site; pilot excavation of the
burn/burial area to determine the composition of the magnetic anomaly; removal
236
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
of the two tanks, concrete pads, and contaminated soils; and point source runoff
diversion.
This alternative is the most effective in terms of removing the threats
posed by the site and complies with CERCLA. This remedy is also cost-effective,
is expected to meet all ARARs, and uses permanent solutions and treatment
technologies to the maximum extent practicable.

POWERSVILLE LANDFILL SITE
POWERSVILLE, GEORGIA
HRS Score: 35.53 NPL Rank: 517
Background
The Powersville Landfill site occupies approximately 15 acres of rural land
in Powersville, Peach County, Georgia. The surrounding land is used
predominantly for general crop farming, with some acreage devoted to orchards
and cattle grazing. The Providence aquifer, located beneath the site, provides
water for irrigation and consumption.
Originally used as a borrow pit, the site began receiving municipal and
industrial wastes in 1969. In 1973, a portion of the landfill was formally
established as a disposal site for pesticides and other hazardous wastes.
However, citizen complaints and State investigations indicated that pesticide
wastes were also discarded in the municipal section of the landfill prior to
1973. In March 1977, the Georgia Department of Natural Resources Environmental
Protection Division (EPD) recommended that t^e site be closed because of its
location above the Providence aquifer. The site was included on the NPL in
1983.
EPA initiated a remedial investigation/feasibility study (RI/FS) of the
site in December 1984. In support of the RI/FS, EPA conducted an endangerment
assessment to evaluate risks to public health. Preliminary investigations
revealed contamination in the soil and ground water, both of which provide
potential pathways for migration of contaminants. A draft FS for remedial
alternatives was completed in July 1987, and the ROD was signed September 30,
1987.
Description of Site Work
The RI detected the presence of chlorinated organics and pesticides in both
soil and ground water. Contaminants of concern in ground water included benzene
hexachloride (BHC), vinyl chloride, lead, and 1,2-dichloroethane. BHC and 1,2-
dichloroethane were also found to be soluble in the soil. The endangerment
assessment indicated a potential long-term health risk associated with the
consumption of ground water from wells. Minimal risk was found to be associated
with direct contact with landfill surface soils by future residents of the area.
Description of Feasibility Study
EPA developed a number of remedial alternatives to address ground-water,
surface-water, and soil contamination at the site. Alternatives were screened
on the basis of cost, effectiveness, implementability, and compliance with
applicable or relevant and appropriate requirements (ARARs). Preference was
given to permanent solutions and alternative treatment technologies. After an
238
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
initial screening, the following combinations of alternatives were retained for
further evaluation:
(1) No action, with institutional controls on the use of
ground water and on the site itself;
(2) Capping of the hazardous waste and municipal fill
areas;
(3) Excavation and on-site incineration of the hazardous
waste area, and capping of the municipal fill area;
(4) Stabilization/solidification of the hazardous waste
area, with capping of the municipal fill area;
(5) Alternative 2 with ground-water pumping and treatment;
(6) Alternative 3 with ground-water pumping and treatment;
(7) Alternative 4 with ground-water pumping and treatment;
(8) Alternative 2 with provision of an alternative drinking
water supply;
(9) Alternative 3 with provision of an alternative drinking
water supply;
(10) Alternative 4 with provision of an alternative drinking
water supply;
(11) Alternative 5 with provision of an alternative drinking
water supply;
(12) Alternative 9 with ground-water pumping and treatment;
and
(13) Alternative 7 with provision of an alternative drinking
water supply.
ARARs identified in the FS as "applicable or relevant" included the Safe
Drinking Water Act (SDWA), the Resource Conservation and Recovery Act (RCRA),
the Clean Air Act (CAA), the Ground Water Protection Strategy, and the Clean
Water Act (CWA).
Community concern regarding the Powersville site was particularly high
while the landfill was receiving waste during the 1960s and 1970s. Following
the discovery of ground-water contamination in 1983, citizens began requesting
sampling of their wells, and press coverage of the site increased. On August
4, 1987, EPA held a public meeting to discuss findings of the RI/FS . During the
3-week comment period, the major concern expressed by residents was whether the
quality of drinking water was sufficiently high.
239
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Selected Remedy
The remedial action alternative recommended for the Powersville Landfill
is Alternative 8, capping the hazardous waste and municipal landfill areas
coupled with provision of an alternative drinking water supply. Institutional
controls will be established to prohibit drilling of wells in the area.
The caps will be designed to minimize flow of liquids through the landfill
over the long term and should reduce or eliminate the mobility of contaminants
in both disposal areas. The alternative drinking water supply system will
provide a reliable, long-term source of drinking water to nearby residents.
Although adding a new drinking water system will not alleviate site
contamination, it will reduce long-term health risks. The remedy is cost-
effective, uses permanent treatment technologies to the maximum extent
practicable, will protect public health, and is expected to meet ARARs. Capping
and installation of an alternative water supply system are both relatively
simple and established technologies.
The State of Georgia has concurred with EPA's selection of the recommended
alternative. Because the site was operated by a county of the State, the State
must pay 50 percent of remedial costs. If a more costly alternative is
ultimately chosen, the State may disapprove all or some portions of the
approach.

NEWPORT DUMP SITE
WILDER, KENTUCKY
HRS Score: 37.63 NPL Rank: 453
Background
The Newport Dump site is a former municipal landfill located in the City
of Wilder (population 633), about three miles south of Newport, a suburb of
Cincinnati, Ohio. The 39-acre site is bounded on the north and east by a small
industrial park and on the west by the Licking River, a tributary of the Ohio
River. About 250 feet downstream of the site is the main raw water intake for
the Kenton County Taylor Mill water treatment plant, which serves about 75,000
consumers in the nearby counties. A stream on the south of the landfill drains
to the Licking River.
The site was used by the City of Newport for disposal of residential and
commercial wastes from the late 1940s until its closure in 1979. During this
time, the City was cited for numerous permit violations including open burning,
absence of daily cover, on-site ponding of water, uncovered refuse, presence of
leachate, and handling hazardous waste without a permit. The landfill was
closed in 1979 but the final closure plan was never fully implemented.
Ownership was transferred to the Northern Kentucky Port Authority (NKPA) with
the understanding that the NKPA would remediate the site.
NKPA activities included partial construction of collection trenches and
landfill slopes. Although the NKPA made these initial remedial efforts, it
lacked adequate funding to implement the agreed order with the State of Kentucky
for closure. Subsequent site inspections indicated leachate breakouts
containing lead, chromium, and PCBs, seeping into the Licking River. In 1984,
the EPA placed the site on the NPL. A draft remedial investigation/feasibility
study (RI/FS) was submitted in November 1986, and the ROD was signed March 27,
1987.
Description of Site Work
EPA initiated the RI investigation in 1985 and completed it in 1986. The
major concern at the site was that leachate would migrate into the Licking River
and the unnamed stream to the south and enter the raw water intake located
across the Licking River. The RI assessed the nature and extent of on-site and
off-site contamination, and evaluated exposure hazards to human health and the
environment in the area surrounding the Newport Site. Specifically, the RI
assessed the levels and pathways of ground-water contaminants, determined
contaminant levels in the Licking River and the unnamed stream and in surface
and subsurface soils, and evaluated the effect of leachate on aquatic organisms.
Results of the chemical analysis indicated that contaminant levels in the
surface soils, surface water, and sediment downstream all were below accepted
health criteria. However, the shallow on-site ground water, both immediately
below the waste and at the banks of the Licking River and unnamed stream,
contained above health base levels of some heavy metals and organics.
241
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
The purpose of the FS, completed in late 1986, was to identify remedies to
mitigate contamination at the dump site in order to remove potential risks to
human health and the environment. Consideration of the remedial action
alternatives took into account the CERCLA provisions that permanent solutions
and treatment technologies be chosen to the maximum extent practicable, and that
the remedy attain applicable or relevant and appropriate requirements (ARARs).
The major ARARs considered were the Resource Conservation and Recovery Act
(RCRA) requirements for ground-water cleanup, the Floodplain Management
Executive Order, the Clean Water Act (CWA), the Occupational Safety and Health
Act (OSHA), and EPA's Ground-water Protection Strategy.
In addition to "no action" and "no action with monitoring" alternatives,
four remedial action alternatives were evaluated:
(1) Multi-media monitoring, leachate collection, regradirig,
and revegetation;
(2) RCRA capping the entire site, repairing the leachate
collection system, and installing a gas collection aind
treatment system;
(3) Extensive excavation and solidification/stabilization
that would require separation of waste material,
backfilling, and regrading; and
(4) Excavation, disposal of waste in an off-site landfill,
backfilling, regrading, and revegetation.
At a public meeting held in Newport during March 1987 the general concern
was whether had EPA successfully determined the nature and extent of
contamination and had considered practical alternatives to remedy the site.
Description of Selected Remedy
The selected alternative action (Alternative 1) required monitoring,
leachate collection, regrading, and revegetation -- specifically, ground-water,
surface-water and gas monitoring using monitoring wells and sampling uptakes,
repair and replacement of the existing leachate collection system to prevent
migration of leachate, and regrading of the landfill bank to prevent further
erosion. The cost for this remedy was approximately one million dollars.
This alternative is cost-effective and protective, is expected to attain
ARARs, and uses treatment technologies to the maximum extent practicable.
Although this remedy does not include permanent treatment, it was considered
economically viable and technically adequate due to the minimal contamination
found in surface soil and ground-water discharge.

SODYECO SITE
CHARLOTTE, NORTH CAROLINA
HRS Score: 51.93 NPL Rank: 151
Background
The Sodyeco site is located on the Catawba River, 10 miles west of
Charlotte, North Carolina. Approximately 20 to 30 people live within 1/4 mile
of the site. Surface drainage from the west side of the site is directly
discharged into the Catawba River. The 1,300-acre site contains an operational
manufacturing facility consisting of production units and a wastewater treatment
facility, which are currently owned by Sandoz Chemicals Corporation. The
manufacturing facility began producing liquid sulfur dyes in 1936 under the
ownership of Southern Dyestuff Company (Sodyeco) but now produces specialty
chemical products for the agrochemical, electronic, explosive, lithographic,
pigment, plastic, rubber, and general chemical industries. Waste materials were
disposed of in on-site landfills, storage pits, and settling ponds.
In September 1980, organic solvents were detected in the facility's potable
water well and in adjacent water supply wells. Residents of five homes were
evacuated, and the facility water supply source was changed from ground water
to the Catawba River. Results of a site investigation conducted by EPA in June
1982 revealed the presence of volatile organic contaminants (VOCs) in the ground
water and surface water on the site. The site was placed on the NPL in December
1982 because of its proximity to potable water wells and the presence of two
municipal water intakes on the Catawba River.
EPA and Sandoz signed a remedial investigation/feasibility study (RI/FS)
consent agreement in February 1986. Because of the agreement, no potentially
responsible party (PRP) search was necessary. The final RI report and a draft
FS report were prepared by Sandoz under the consent agreement and released to
the public in August 1987. The ROD was signed September 24, 1987.
Description of Site Work
The RI included soil, sediment, surface-water, and ground-water sampling
at five different areas identified as sources of contamination. Results
indicated that some portion of both the upper and lower aquifers had been
contaminated with VOCs. As a result of volatilization and dilution, however,
this contamination did not appear to have affected the Catawba River. Because
the aquifers are not used for drinking water, potential risks to human health
from exposure to on-site organic contaminants via inhalation, ingestion, and
dermal contact are low under present use conditions at the site. There is
potential for increased human health risks, however, if the ground water becomes
a source of drinking water.
Description of Feasibility Study
The purpose of the FS conducted by Sandoz was to identify actions to
mitigate contamination in soil and ground water and to reduce risks to human
243
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
health and the environment. Remedial alternatives under consideration that
passed initial screening were:
(1) No action; ground-water monitoring only;
(2) Ground-water recovery and treatment;
(3) Capping, soil excavation and incineration, and ground-water
recovery and treatment;
(4) Capping, soil excavation and thermal stripping, and ground-
water recovery and treatment;
(5) Capping, innovative soil treatment, excavation, and
incineration, and ground-water recovery and treatment; and
(6) Capping, natural flushing, excavation, and incineration,
and ground-water recovery and treatment.
Federal applicable or relevant and appropriate requirements (ARARs) under
consideration included Maximum Contaminant Levels (MCLs) and MCL goals (MCLGs)
under the Safe Drinking Water Act (SDWA); Water Quality Criteria (WQC) under the
Clean Water Act (CWA); National Ambient Air Quality Standards (NAAQS) under the
Clean Air Act (CAA); permitting and incineration standards under the Resource
Conservation and Recovery Act (RCRA); Hazardous Materials Transportation Act
(HMTA) standards; Occupational Safety and Health (OSHA) planning requirements;
National Pollutant Discharge and Elimination System (NPDES) standards for
treated ground water; and North Carolina MCLs adopted from Federal SDWA
standards.
During public meetings citizens expressed a desire for remedial action at
the site. No public opposition is expected if the remedial alternative
recommended below is implemented.
Description of Selected Remedy
The remedy recommended for the Sodyeco site included extraction, treatment,
and discharge of ground water; possible soil excavation and off-site
incineration; capping; and on-site treatment of contaminated soils left on site
(Alternative 5). The innovative soil treatment technologies to be considered
are flushing, soil washing, thermal processing, and in situ steam stripping.
This recommended remedy permanently and significantly reduces the volume and
mobility of contaminants in the soil and is expected to meet Federal and State
ARARs. Long-term operation and maintenance of the asphalt cap and long-term
ground-water monitoring will be required to ensure the effectiveness and
permanence of the remedy.

GEIGER (C&M OIL) SITE
CHARLESTON COUNTY, SOUTH CAROLINA
HRS Score: 3225 NPL Rank: 640
Background
The Geiger (C&M Oil) site is located in central Charleston County, about
10 miles west of the City of Charleston, South Carolina. The 5-acre site is
located in a sparsely populated rural area that includes environmentally
sensitive wetlands that are a critical habitat for several Federally-listed
endangered and threatened species. The site, which was formerly used to
incinerate waste oil, includes eight unlined lagoons constructed between 1969
and 1971 to hold waste oil prior to recycling and incineration.
In late 1971, in response to complaints from area residents, the South
Carolina Pollution Control Authority (SCPCA) ordered that all incineration and
waste disposal activities be stopped. After several serious oil spills in 1971
and 1974, the Charleston County Health Department closed the site and C&M Oil
Distributors, Inc., purchased all reclaimable oil at the site. In 1982, the
site was purchased by George Geiger, who filled in the lagoons with soil so that
the site could be used to store equipment for his pile driving company.
The EPA, with aid from the South Carolina Department of Health and
Environmental Control, initially investigated the site in February 1980. The
waste oil was found to contain volatile organic compounds (VOCs), heavy metals,
and PCBs. Although samples from two private wells upgradient from the site
indicated no contamination, the ground water near the lagoons was found to
contain heavy metals and VOCs. The site was included on the NPL in September
1983 and EPA assumed lead responsibility. Notice letters were sent out to
potentially responsible parties (PRPs) in 1984; however, because no financially
viable PRPs were identified, EPA initiated a Federal lead remedial investigation
(RI) under Superfund in July 1985. The ROD was signed June 1, 1987.
Description of Site Work
The EPA initiated an RI in 1985 to determine the extent of contamination
in the shallow aquifer and in the soil, and to determine whether contamination
had migrated off site through surface-water runoff. The RI, completed in July
1986, determined that the soil was contaminated with lead, chromium, mercury,
and PCBs; however, these contaminants did not appear to be migrating from the
site. Lead, cadmium, VOCs, and other organic compounds were also found in the
ground water beneath the site. Samples from local residential wells indicated
that contaminants had not migrated into drinking water. However, a public
health evaluation conducted as part of the RI concluded that contaminated ground
water could potentially migrate toward residential wells and the sensitive
wetlands.
245
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
The cleanup objectives of the remedial action were to protect human health
and environment from exposure to contaminated soils, prevent off-site movement
of contaminated ground water, and restore contaminated ground water to levels
protective of human health and the environment. The alternatives were divided
into four groups: ground-water remediation, soil remediation, no action, and
no action with monitoring alternatives. The following alternatives were
considered in the feasibility study (FS):
(1) Ground-water extraction, air stripping, and disposal
at privately-owned treatment works;
(2) Ground-water slurry wall and cap;
(3) Cap or vegetative or gravel cover over the area of
highest soil contamination;
(4) Partial soil excavation, on-site disposal, and cap or
vegetative cover; and
(5) Soil excavation and off-site disposal.
The major applicable or relevant and appropriate (ARARs) considered for
this site were related to ground water. Ground water in the uppermost aquifer
at the site is comparable to Class I water under the EPA Ground-water Protection
Strategy (GWPS). The ground water is highly vulnerable to contamination; is a
source of drinking water for nearby residents; and discharges into wetlands
inhabited by endangered species, for example, the bald eagle, the wood stork,
and the American alligator. Resource Conservation and Recovery Act (RCRA)
regulations require a level of cleanup of contaminated water sufficient to
achieve Maximum Contaminant Levels (MCLs). Other ARARs identified included the
Safe Drinking Water Act (SDWA), Clean Water Act (CWA), National Pollutant
Discharge Elimination System (NPDES), Endangered Species Act (ESA), and National
Ambient Air Quality Standards (NAAQS) for incineration.
Description of Selected Remedy
Based on results of the investigations and the comments received from the
public, EPA selected a remedy that includes pumping and on-site treatment of
ground water and on-site thermal treatment of contaminated soil. This
alternative meets CERCLA preferences for treatment by permanently and
significantly reducing the volume of hazardous substances in the ground water
and reducing the volume of contaminants in the soil. The remedy entails pumping
water from the ground, applying treatment technologies appropriate to remove
metals and VOCs, and discharging treated water into a nearby stream. All
contaminated soil will be excavated, and organic contaminants destroyed in an
on-site mobile thermal destruction unit. Inorganically contaminated soil will
be treated through stabilization and solidification. Treated soil will be
placed back into the excavated area.

INDEPENDENT NAIL COMPANY SITE
FIRST OPERABLE UNIT
BEAUFORT, SOUTH CAROLINA
HRS Score: 57.90 NPL Rank: 62
Background
The Independent Nail Company (INC) site is located near Beaufort, South
Carolina, 40 miles northeast of Savannah, Georgia. From 1969 to 1980, the Blake
and Johnson Company manufactured screws and fasteners on this 25-acre site. As
part of its manufacturing process, the company discharged approximately 33,000
to 75,000 gallons per day of plating wastewater into an unlined infiltration
lagoon. The wastewater contained organic cleaning solvents, phosphate, cyanide,
chromium, cadmium, lead, mercury, nickel, zinc, copper, and iron.
In 1975, the South Carolina Department of Health and Environmental Control
(SCDHEC) discovered that a break in the lagoon allowed wastewater to enter a
drainage ditch located north of the lagoon. Further ground-water investigations
by the State in 1975 and in 1980 indicated that concentrations of chromium and
lead in the ground water exceeded drinking-water standards, and that cadmium,
nickel, and zinc also were contaminating the ground water. The State took no
action. In June 1980, INC purchased the plant and since that time has not
discharged any wastewater into the lagoon. Additional sampling done in 1985,
however, showed no metal contaminants at concentrations exceeding drinking-water
standards.
EPA added the INC site to the NPL in September 1984 and assumed lead
responsibility for the site. Although EPA initially determined that the site
required no action, the SCDHEC stressed the seriousness of land disposal
practices at the site due to its location in a major recharge zone. EPA divided
the site into two operable units. The first operable unit addressed soil,
surface-water, and sediment contamination; the second operable unit will address
ground-water contamination. EPA completed the remedial investigation/
feasibility study (RI/FS) for the first operable unit in July 1987 and signed
the ROD on September 28, 1987. EPA initiated the RI/FS for the second operable
unit in July 1987. Both the Blake and Johnson Company and INC were identified
as potentially responsible parties (PRPs). A notice letter was sent to the PRPs
but they declined to participate.
Description of Site Work
The RI, conducted from September through November 1986, determined the
extent of contamination in the soil, surface water, and sediments on the site
and in the drainage paths from the lagoon. The RI results indicated that soil
contaminated with cadmium, chromium, nickel, and zinc, was found primarily in
the lagoon, in areas within the fence, and in two areas outside the fence.
Surface-water samples taken from the ditches showed that only zinc was present
in detectable quantities. Samples taken from the lagoon revealed elevated
levels of nickel and zinc. EPA detected high concentrations of cadmium,
chromium, nickel, zinc, and cyanide in sediment samples taken at the same
locations where surface-water samples were taken. An endangerment assessment
indicated that the primary exposure pathway for cadmium, chromium, nickel, and
247
-------

zinc was through direct contact with surface soils and inhalation of airborne
dust.
Description of Feasibility Study
The purpose of the FS for the first operable unit was to identify remedial
actions to minimize soil and sediment contamination and prevent further
contamination of ground water. Nine potential remedial alternatives were
identified:
(1) No action;
(2) Soil washing and vegetative cover;
(3) Attenuation of soil contamination and vegetative cover;
(4) Solidification/stabilization of soils;
(5) Immobilization of soil by addition of clay and vegetative
cover;
(6) Immobilization of soil by addition of lime and vegetative
cover;
(7) Vegetative cover over lagoon area;
(8) Capping of lagoon area; and
(9) Off-site disposal of all contaminated soil.
Each alternative was evaluated against the CERCLA mandate of using
permanent solutions and treatment technologies to the maximum extent practicable
and the CERCLA criteria of effectiveness, implementability, and cost-
effectiveness .
Applicable or relevant and appropriate requirements (ARARs) identified for
the site were Occupational Safety and Health Act (OSHA) regulations, Safe
Drinking Water Act (SDWA) Maximum Contaminant Levels (MCLs), Clean Water Act
(CWA), Endangered Species Act (ESA), Clean Air Act (CAA), and State Drinking-
Water Standards.
EPA finalized a Community Relations Plan in January 1987. There were no
requests from residents for a public meeting, and residents did not comment on
the FS.
Description of Selected Remedy
The remedy EPA selected consists of treating contaminated soil by means of
stabilization/solidification (Alternative 4). Following treatment, the
soil/sediment will be placed in the excavated lagoon, covered with 6 inches of
soil, and revegetated. The results of the ground-water investigation in the
second operable unit will determine the necessity for long-term monitoring.
248

This alternative uses permanent treatment to reduce the mobility of the
contamination. It is expected to be protective of human health and the
environment and to attain ARARs.

PALMETTO WOOD PRESERVING SITE
DIXIANA, SOUTH CAROLINA
HRS Score: 38.43 NPL Rank: 420
Background
The Palmetto Wood Preserving (PWP) site is a decommissioned wood preserving
facility located in the rural community of Dixiana, South Carolina, 6 miles
southwest of Columbia. Wood treatment operations at the PWP site began in 1963;
processes utilized there include a fluoride-chromate-arsenate-phenol process and
an acid-copper-chromate process. In 1980, the new owners, Eastern Forest
Products, switched to a chromate-copper-arsenate process.
During late 1981 and early 1982, the South Carolina Department of Health
and Environmental Control (SCDHEC) received complaints of green liquids running
off the PWP site and puddling on the adjacent property and roads during heavy
rains. In response, SCDHEC inspected the PWP site and collected on-site soil
and water samples. The soil was found to be contaminated with hazardous levels
of chromium and pentachlorophenol (PCP).
In April 1983, copper and chromium were discovered during the drilling of
a new drinking water well 200 feet from the site. As a result, SCDHEC issued
a Consent Order requiring PWP to determine the extent of soil and ground-water
contamination and to develop a plan for disposing of the contaminated materials.
PWP's subsequent study confirmed soil and ground-water contamination beneath the
main process area of the plant site. Plans for further investigations of the
problem were developed by PWP's contractor but were never implemented. At the
end of 1983, SCDHEC turned over responsibility for future work on PWP to EPA.
Notice letters were sent to potentially responsible parties (PRPs) in
January 1985. Two PRPs were found but were judged not to be viable after a
financial assessment. PWP ceased operations in 1985. The EPA lead remedial
investigation (RI) was initiated in April 1986 and completed in January 1987;
the feasibility study (FS) was completed in August, and the ROD was signed
September 30, 1987.
Description of Site Work
The RI conducted by EPA revealed metal contamination in the soil, including
elevated concentrations of chromium (2,200 ppm) and arsenic (6,200 ppm). Ground
water below the site also is highly contaminated with copper, chromium, and
arsenic, at levels above standards acceptable for drinking water. This metal
contamination presents potential cancer risks through the following possible
human exposure pathways: inhalation of contaminated dust; irigestion of
contaminated soil; and drinking of contaminated ground water. Upon consultation
with the Agency for Toxic Substances and Disease Registry (ATSDR), cleanup
criteria for soils were set at 627 ppm for chromium and 200 ppm for arsenic.
250
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
The FS, completed by EPA in August 1987, listed the following cleanup
objectives: to protect against exposure to contaminated on-site soils; to
prevent off-site movement of contaminated ground water; and to restore
contaminated ground water to protective levels. Based on these objectives, the
following alternatives were developed and evaluated:
(1) Alternatives for Ground-water Remediation:
• Slurry wall and impermeable cap;
• Slurry wall with an encapsulation cell;
• Ground-water extraction, filtration, ion exchange, and
off-site discharge;
• Ground-water extraction, reduction, precipitation,
filtration, and off-site discharge;
• Ground-water extraction, filtration, ion exchange,
precipitation, filtration, and off-site discharge; and
• No action;
(2) Alternatives for Soil Remediation:
• Surface capping;
• On-site containment/encapsulation;
• Extraction/soil flushing;
• Excavation and off-site disposal; and
• No action.
The following applicable or relevant and appropriate requirements (ARARs)
were identified: Safe Drinking Water Act (SDWA) Maximum Contaminant Levels
(MCLs); National Pollutant Discharge Elimination System (NPDES) regulations;
Resource Conservation and Recovery Act (RCRA) excavation and soil flushing
regulations; Federal and State ambient air quality standards; and State drinking
water standards.
At a public meeting to discuss the remedial alternatives developed in the
FS, the public expressed support for treatment of ground water and flushing of
contaminated soil.
Description of Selected Remedy
The selected remedy will consist of the following activities:
• Extraction of contaminated ground water, treatment on
site to achieve SDWA MCLs, filtering, and discharge off
site;
• Installation of a municipal water line or the drilling
of new wells for nearby residents;
• Excavation of contaminated soils;
251
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
• On-site flushing of soil with an acidic water solution
to remove arsenic and chromium;
• Removal of heavy metal ions in soil through ion-
exchange treatment;
• Testing for decontaminant verification;
• Pumping of flushing solution to an on-site water
treatment facility for processing and recirculation
through soil; and
• Transport of treated soil back to excavated area, where
natural aeration will be supplemented with tilling and
compaction.
This remedy is expected to permanently and significantly reduce the volume
and/or mobility of contaminants in the soil and ground water, and is cost-
effective in comparison with other alternatives. The State of South Carolina
concurred with the selected remedy, but pointed out that its funds for cost
sharing are limited. Although the State presently has funding to cover its part
of this remedial action, it is concerned about funding problems on future
remedial actions at other NPL sites in the State.

JOHNS-MANVILLE SITE
WAUKEGAN, ILLINOIS
HRS Score: 3820 NPL Rank: 428
Background
The Johns-Manville disposal site is located near the City of Waukegan,
along Lake Michigan, in northeastern Illinois. There are approximately 200
homes within 1 mile of the western edge of the site. The site covers
approximately 120 acres of land that is owned by the Manville Services
Corporation (previously the Johns-Manville Sales Corporation). The Manville
Services Corporation produces a wide range of building materials. Waste
materials from the Manville plant have been disposed of in pits on the site
since 1922; wastes present include asbestos, lead, chrome, thiram, and xylene.
An asbestos disposal pit, a sludge disposal pit, and other miscellaneous
disposal pits still are active. Materials from the Manville wastewater
treatment system were also settled out in unlined ponds and waterways at the
site and periodically transferred to the sludge disposal pit.
A 1982 study by EPA indicated that concentrations of asbestos fibers
ranging in size from 2.5 to 15 micrometers were present at the site and downwind
of the site, and asbestos fibers of a size less than 2.5 micrometers were also
present on site in elevated concentrations. The site was listed on the NPL in
December 1982. Enforcement negotiations with the potentially responsible party
(PRP), the Manville Services Corporation, were completed in May 1987. The ROD
was signed June 30, 1987.
Description of Site Work
The EPA lead remedial investigation (RI) at the site was completed in July
1985 and included sampling of air, ground water, soil, and the waters of Lake
Michigan. The RI indicated that concentrations of asbestos fiber exceeded
applicable health-based water quality criteria at all ground-water and surface-
water sampling locations. An air quality survey for lead and total suspended
particulates (TSP) indicated that air emissions from the site were a potential
problem. In addition, elevated levels of metals were found in the soils. The
results of the RI indicated the need to take action to prevent the release of
asbestos and TSPs into the air, and the need to monitor and, if necessary,
remediate contaminants in the site ground water and in Lake Michigan.
Description of Feasibility Study
EPA completed the feasibility study (FS) in January 1987. The objectives
of the remedial action were to ensure that: (1) releases of asbestos to air
were eliminated and that releases of other contaminants to the air are
mitigated; (2) direct contact with waste materials and soils was minimized or
eliminated; and (3) concentrations of contaminants in ground water and surface
water exceeding standards for human health and aquatic life were detected and
effectively remediated.
253
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
An initial screening process narrowed the alternatives to the following:
(1) No action;
(2) Grading and seeding of the waste materials and soils,
closure of the asbestos pit, and air emissions
contingency plans;
(3) Soil covering with vegetation, placement of riprap or
new soil on slopes of the settling basins and waste
disposal area, closure of asbestos disposal pit, and
air emissions contingency plans;
(4) On-site landfilling, including installation of a multi-
layer liner, multi-layer cap, and collection and
treatment of leachate and runoff; and
(5) Off-site landfilling, including removal and disposal
of soils in a landfill.
All alternatives included a ground-water detection monitoring system and a
ground-water/surface-water contingency plan.
Applicable or relevant and appropriate requirements (ARARs) included the
Clean Air Act (CAA) National Emission Standards for Hazardous Air Pollutant
(NESHAP) requirements and National Ambient Air Quality Standards (NAAQs), the
Clean Water Act (CWA), Illinois Water Quality Standards, the Safe Drinking Water
Act (SDWA), the Great Lakes Water Quality Agreement of 1978, the U.S. EPA
Ground-water Protection Strategy, the Resource Conservation and Recovery Act
(RCRA), the Occupational Safety and Health Act (OSHA), and other State of
Illinois requirements.
Approximately 20 people attended a public meeting in February 1987 to
discuss the RI/FS. Ten individuals and organizations submitted comments during
the public comment period on the FS. The Manville Sales Corporation submitted
comments disagreeing with the proposed thickness of the cover. Other commenters
expressed concern about funding for a cleanup, the use of the property after
cleanup, the degree of endangerment, and the public health effects presented by
the site.
Description of Selected Remedy
The recommended alternative contained multiple approaches, including
grading and covering of the waste materials and soils at the site, and
installing a cover of vegetation. The active disposal pits will continue to
operate but the asbestos pit will be closed in June 1989 and covered. Riprap
will be placed on the slopes of the settling basins to prevent erosion, and a
ground-water and surface-water detection monitoring system will be established
on site to detect any leaching of contaminants. In addition, an air monitoring
system will be used to determine whether the remedy reduces airborne contaminant
levels. Miscellaneous remedies, such as the cleanup of debris, fencing, and the
posting of signs, also will be instituted.
254
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
The State of Illinois concurred with the selected remedy. In response to
public comments, an air monitoring program, an associated contingency plan, and
a sampling plan for active waste disposal areas on site were added to the
recommended alternative.
The alternative is expected to meet the ARARs for the site. Presently, the
site achieves the NAAQs for lead. However, initial grading and construction at
the site may temporarily generate levels of contaminants above the NAAQ
standards. Soil covering should reduce the contaminant levels in Lake Michigan
below EPA Ambient Water Quality Criteria and Illinois Water Quality Standards.
Additionally, the alternative fulfills the CERCLA preference for a permanent
remedy.

ENVIRO-CHEM CORPORATION/
NORTHSIDE SANITARY LANDFILL
ZIONSVILLE, INDIANA
ECC HRS Score: 46.44 ECC NPL Rank: 240
NSL HRS Score: 46.04 NSL NPL Rank: 249
Background
The Enviro-Chem Corporation (ECC) and the Northside Sanitary Landfill (NSL)
sites are located in a rural area of Indiana, 10 miles northwest of
Indianapolis. ECC, a former solvent processing and reclaiming facility,
occupies about 7 acres immediately west of NSL, a 70-acre landfill containing
both hazardous and non-hazardous wastes. Farmland borders the sites and about
50 residences are located within a mile of the sites. Finley Creek, which flows
along the eastern and southern edge of the NSL site, eventually feeds into a
reservoir supplying approximately 6 percent of the drinking water for the City
of Indianapolis.
ECC began operations in 1977 involving the recovering, reclaiming, and
selling of primary solvents, oils, and other industrial wastes. ECC was
permitted to dispose of still bottoms and oily wastes at NSL. Accumulation of
contaminated storm water, poor management of drum inventory, and several spills
prompted EPA and State investigations of the ECC site. In 1981, after a number
of violations, the Boone County Circuit Court issued a Consent Decree
prohibiting ECC from using the NSL for disposal of wastes. ECC failed to
satisfy the Consent Decree and was ordered to stop operations. In August 1982,
ECC was found to be insolvent. From 1983 to 1984, surface contaminants were
removed from the site and treated. The ECC site was listed on the NPL in
September 1983.
The NSL site began operations sometime before 1960 and was first ordered
to cease operations in 1974 due to reported operational deficiencies. Use
resumed and reports of disposal of unapproved waste at NSL continued through the
late 1970s. In 1980, the owner filed a Resource Conservation and Recovery Act
(RCRA) Part A application and operated as an existing hazardous waste disposal
facility until November 1985 when EPA denied a RCRA Part B application. The NSL
site was placed on the NPL in September 1984. In February 1987, after a series
of investigations, the Indiana Solid Waste Management Board ordered NSL to
accept no additional solid waste except that needed to contour the site. NSL
has appealed and the results of the hearing are not known at this time.
Because similar remedial actions are required at both sites, a joint ROD
was signed on September 25, 1987. One thousand potentially responsible parties
have been identified and three steering committees exist to organize the effort:
(1) ECC settlors (1983 Decree), (2) ECC non-settlors, and (3) NSL Steering
Committee. The landfill owner represents himself as a separate entity. EPA
will be seeking cleanup funds and reimbursement for previously incurred costs.
The ECC settlors have been released from responsibility for most previously
incurred costs and half of the remedial investigation/feasibility study (RI/FS)
costs.

Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Site Work
Emergency actions at the ECC site have eliminated major surface sources of
contamination. The contamination remaining in the soil includes volatile
organic chemicals (VOCs), polynuclear aromatic hydrocarbons (PAHs), and
polychlorinated biphenyls (PCBs). The EPA lead RI, completed in 1986, also
indicated organic contamination in the ground water off site. Ground-water
contamination appears in a glacial till water-bearing unit below the site due
to leaching.
As of April 1987, NSL was continuing to operate as a solid waste landfill.
The RI for that site revealed contamination in the subsurface soil, surface
water and sediments, leachate, and ground water. Contaminants include volatile
organics, oil and grease, inorganics, and pesticides.
Description of Feasibility Study
Although a separate FS was conducted for each site, a third report,
entitled "Combined Alternatives Analysis (CAA) Report, NSL and ECC," was
prepared to discuss a combined remedy. Remedial goals were identified for each
medium: soil and landfill contents, landfill leachate, ground water, surface
water, and sediment. The goals were to minimize direct contaminant contact,
control migration to ground and surface water, and minimize contaminant
consumption. Nine alternatives were evaluated:
(1) No action;
(2) Soil cover and leachate collection and treatment with
access restrictions;
(3) RCRA cap and leachate collection and treatment, with
access restrictions;
(4) Soil cover, leachate collection, ground-water
interception and treatment, with access restrictions;
(5) RCRA cap, leachate collection, ground-water
interception and treatment, with access restrictions;
(6) RCRA cap, leachate collection, ground-water isolation
and treatment, with access restrictions;
(7) RCRA cap, leachate collection, ground-water isolation
and treatment, ECC soil vapor extraction, with access
restrictions;
(8) RCRA cap, leachate collection, ground-water isolation
and treatment, ECC soil incineration, with access
restrictions; and
(9) On-site RCRA landfill with access restrictions.
257
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
The alternatives were evaluated for compliance with CERCLA cleanup goals,
including preference for treatment that permanently and significantly reduces
the volume, toxicity, or mobility of hazardous substances. The evaluation
considered the following applicable or relevant and appropriate requirements
(ARARS): RCRA closure and post-closure requirements; Indiana closure and post-
closure requirements; State of Indiana Water Quality Criteria; RCRA and Indiana
Environmental Management Act measures to prevent releases of contaminants; RCRA
requirements for corrective action; RCRA ground-water protection standards and
concentration limits; the Clean Water Act (CWA) National Pollutant Discharge
Elimination System (NPDES); Executive Orders 11988 and 11990 for Floodplain
Management and Protection of Wetlands; and the Indiana Department of Natural
Resources Flood Control Act.
Description of Selected Remedy
EPA's recommended alternative (Alternative 5) includes a RCRA-compliant cap
and surface controls, monitoring, leachate collection, ground-water interception
and treatment, and access restrictions. The selected remedy is consistent with
the CERCLA goal of mitigating and minimizing threats to human health and the
environment. The selected remedy is expected to attain ARARs identified for the
two sites. Public comments received on the FS and the CAA Report indicated
residents were concerned that a permanent remedy be introduced as soon as
possible at the sites. The State of Indiana concurred with the selected remedy.

MARION/BRAGG LANDFILL SITE
SOURCE CONTROL OPERABLE UNIT
MARION, INDIANA
HRS Score: 3525 NPL Rank: 530
Background
The Marion/Bragg Landfill, located just outside the city limits of Marion,
Indiana, 65 miles northeast of Indianapolis, was used as a sand and gravel quarry
from 1935 until approximately 1961. From 1949 through 1970, Radio Corporation
of America (RCA) leased and used portions of the site for industrial refuse
disposal. Concurrently, from 1957 to 1975, Bragg Construction leased and used
the site as a municipal landfill. Indiana State Board of Health (ISBH)
inspections indicated that the landfill was operated in an unacceptable manner,
although ISBH never formally closed the site. Flammable drummed waste often was
emptied and mixed with the landfill wastes, causing fires. Drums allegedly were
rinsed and resold. Other violations included lack of daily cover, burning of
waste, and pond encroachment.
Notice letters were issued to potentially responsible parties (PRPs),
including Mr. Delmar Bragg, General Plastics Corporation, RCA, the City of
Marion, and the Marion Utility Services Board, and a meeting was held in November
1985 to provide the PRPs an opportunity to work cohesively and to respond to
EPA's work plan. In December 1985, Enforcement and Regional Counsel determined
that EPA should initiate the remedial investigation/feasibility study (RI/FS).
Little or no interaction has occurred with the PRPs since that time. The RI/FS
was completed in July 1987, and the ROD was signed September 30, 1987. An
interim remedy for source control was selected for this site pending further
ground-water studies.
Description of Site Work
EPA initiated the RI in March 1985 and completed it in June 1987. Results
indicated that surficial soils at the site were contaminated with Bis (2-
ethylhexyl) phthalate, cadmium, lead, mercury, and several polycyclic aromatic
hydrocarbons (PAHs). Two leachate seeps at the site were contaminated with
arsenic and other inorganic metals. PAH and arsenic contamination in the
leachate seep exceeded levels acceptable for direct contact (1 x 1(T6) .
Ground water beneath the site was contaminated with benzene,
trichloroethylene, and arsenic at levels above Clean Water Act (CUA) Water
Quality Criteria (WQC) for human health. Other ground-water contaminants
included phthalate, ammonia, barium, and some heavy metals. The Mississinewa
River, the major receptor of ground water from the site, was found to be
contaminated with ammonia at levels above Indiana WQC. In addition, on-site
ground water contained ammonia at levels that have the potential to harm aquatic
life in the river.
259
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
The FS, completed by EPA in July 1987, identified the following remedial
action goals for the site: (1) minimize risk from direct contact with PAH-
contaminated surface soils and the on-site pond; (2) minimize migration of
arsenic and other contaminants in leachate seeps and surface soils to ground
water and off-site surface water; (3) minimize risk from direct consumption of
contaminated ground water; and (4) minimize migration of contaminated ground
water to surface water. Based on these goals, the following remedial
alternatives were developed and analyzed:
(1) Installation of an Indiana Sanitary Landfill Cap (a 2-
foot clay-type cap and 6 inches of top-soil),
construction of a flood protection levee around the
100-year floodplain, monitoring of ground and surface
waters, and deed restrictions on use of shallow
drinking water wells;
(2) Installation of a Resource Conservation and Recovery
Act (RCRA)-compliant cap (and all the components of
Alternative 1);
(3a) Installation of a slurry wall, ground-water pumping,
and on-site treatment (and all the components of
Alternative 1);
(3b) Installation of a slurry wall, ground-water pumping,
and off-site discharge to local treatment plant (arid
all the components of Alternative 1);
(4a) Similar to Alternative 3a, except construction of a
RCRA-compliant cap rather than a sanitary cap;
(4b) Similar to Alternative 3b, except construction of a
RCRA-compliant cap rather than a sanitary cap; and
(5) No action.
The following applicable or relevant and appropriate requirements (ARARs)
were identified for the site: Indiana Sanitary Landfill requirements, the
Indiana Floodplains Control Act, Indiana WQC, and RCRA surface-water monitoring
requirements.
Description of Selected Remedy
In the remedy selection process, EPA decided that additional ground-water
studies were needed in order to select a ground-water remedy that assures
protection of human health. Therefore, the ground-water treatment alternatives
(3a, 3b, 4a, and 4b) were deferred, and Alternative 1 was selected as an
interim remedy. In concurrence with the execution of the interim remedy, EPA
will conduct fish-sampling, ground-water release studies, and ground- and
surface-water monitoring.
260
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
The selected remedy is implementable and cost-effective. Long-term
effectiveness and permanence will be evaluated best when the ground-water
remediation is completed. Permanent treatment-based solutions, particularly
incineration alternatives, were considered but screened out due to technical and
cost considerations. Such alternatives would take 25 to 100 years to complete,
at a cost of $404 million to $3.4 billion.

SEYMOUR RECYCLING CORPORATION SITE
SEYMOUR, INDIANA
MRS Score: 58.15 NPL Rank: 57
Background
The Seymour Recycling Corporation (SRC) site is located 2 miles southwest
of Seymour, Indiana, in an area used primarily for agriculture. From
approximately 1970 to early 1980, SRC and its corporate predecessor, Seymour
Manufacturing Company, processed, stored, and incinerated chemical wastes at the
site.
In March 1980, 100 homes were evacuated after a chemical reaction released
toxic fumes from the facility. The facility was subsequently closed due to
failure to comply with the terms of a 1978 agreement with the State of Indiana
to improve waste management practices and to cease receiving wastes. In May
1980, the United States filed suit against the owners and operators of the site.
Two potentially responsible parties (PRPs) removed several thousand drums from
the site, and EPA took action to restrict access and control runoff. In 1981,
EPA removed chemicals from tanks at the site and disposed of those wastes at
authorized disposal sites. In the Fall of 1982, the United States and certain
companies that allegedly sent waste to the site reached a settlement agreement.
Under the terms of the consent decree, the settling defendants removed
accumulated wastes and contaminated soil from the site.
From 1982 to 1984, EPA and the State conducted a surface cleanup, removing
drums, tanks, and soil for off-site disposal. Preliminary sampling efforts
indicated that over 70 potential carcinogens, teratogens, mutagens, and acute
and chronic toxicants were present in the soil, surface water, and ground water
at the SRC site.
A case management order was issued in 1984 for negotiations between the
defendants and the EPA. There are approximately 60 defendants, currently named
by the United States in the ongoing suit, who have, in turn, introduced 60
additional third-party defendants. EPA initiated a Remedial Investigation (RI)
that was completed in May 1986. A Phased Feasibility Study (PFS) that, evaluated
the stabilization of the ground-water contamination plume emanating from the
site was completed in August 1986. The ROD was signed September 4, 1987.
Negotiations with PRPs are ongoing.
Description of Site Work
In 1983, EPA initiated an RI to determine the nature and extent of
potential hazards remaining at the site. The endangerment assessment estimated
potential impacts on human health and the environment. The RI identified the
following as major risks associated with the site: 1) off-site migration of
volatile organic compounds (VOCs); 2) potable use by humans of shallow,
contaminated ground water on site; 3) exposure of humans to contaminants in on-
site soils through site use; and 4) on-site and off-site exposure of terrestrial
and aquatic organisms to contaminants from the site.
262
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
EPA collected soil samples during 1984 and 1985 to determine the extent of
the contamination of the soil. Additional sampling was conducted by the U.S.
Fish and Wildlife Service between 1983 and 1985. Ground-water monitoring
conducted at the SRC site by EPA and various contractors detected the presence
of a ground-water contaminant plume containing a high concentration of VOCs.
In addition, analyses of tissues from animals captured in the area surrounding
the SRC site indicated that some contamination from the site migrated to
surrounding land areas and surface waters.
Description of Feasibility Study
The PFS was completed in 1986 to evaluate the stabilization of the ground-
water plume. Remedial alternatives under consideration in the PFS were:
(1) No action;
(2) Off-site soil disposal and ground-water extraction
and treatment;
(3) On-site soil disposal and ground-water extraction
and treatment;
(4) On-site soil incineration and ground-water
extraction and treatment;
(5) Multi-media soil cap and ground-water extraction
and treatment;
(6) In-situ soil washing, multi-media cap, and ground-
water extraction and treatment; and
(7) Vapor extraction, multi-media cap, and ground-
water extraction and treatment.
Federal applicable or relevant and appropriate requirements (ARARs)
considered included Maximum Contaminant Levels (MCLs), MCL goals (MCLGs), and
health advisories under the Safe Drinking Water Act (SDWA); MCLs, Alternate
Concentration Limits (ACLs), and background levels under the Resource
Conservation and Recovery Act (RCRA); verified reference doses (RFDs) for
noncarcinogens developed by an intra-agency EPA workgroup; carcinogen potency
factors (PFs) developed by EPA; and Water Quality Criteria (WQC) under the Clean
Water Act (CWA). Indiana State ARARs considered included narrative and non-
degradation water quality standards, and numerical drinking water standards for
public water supplies. Other State standards considered were closure and post-
closure requirements and land disposal restrictions under RCRA.
The community of Seymour, Indiana, has been concerned about the SRC site
since 1976. The city used a court-held trust fund established as part of a 1983
settlement between EPA and several PRPs to extend the city's municipal water
system to the subdivision on which the site is located. At a public meeting
held by EPA on the October 9, 1986, Seymour community participants expressed the
desire that remedial action be implemented as soon as possible.

Progress Toward Implementing Super-fund: Fiscal Year 1987
Description of Selected Remedy
The remedy selected for the SRC site was a modification of the seventh
alternative listed above: soil vapor extraction, multi-media cap, and ground-
water extraction and treatment. The soil vapor extraction system selected will
remove a substantial amount of the VOCs present in the soil. The application
of soil nutrients will stimulate biodegradation of the remaining non-volatile
organic compounds remaining in the soil. Construction and maintenance of a
multi-media cap will provide protection from direct contact with the remaining
contaminants, reducing the cancer health risk to humans from direct contact with
soil on site and reducing soil exposure risk for terrestrial animals. Capping
will also prevent the small concentrations of slow-moving VOCs remaining in the
soil from further contaminating the ground water. The ground-water pumping and
treatment system will remove nearly all of the VOCs in the ground water, reduce
the cancer risk to humans, and also prevent further contamination of the ground
water. As described above, the selected remedy employs permanent solutions and
treatment technologies and is expected to satisfy ARARs.

LIQUID DISPOSAL INC., SITE
UTICA, MICHIGAN
HRS Score: 6328 NPL Rank: 24
Background
Liquid Disposal Inc., (LDI) is a 6.5-acre site located about 20 miles north
of Detroit in a residential and light industrial area. The site is bordered by
the Clinton River and its floodplain and by a nature study area. LDI operated
from 1968 to 1982 as a commercial incinerator of liquid waste. Major features
of the site include a high-temperature incinerator, a waste liquid lagoon, a
scrubber water lagoon, and numerous above- and below-ground storage tanks.
LDI was closed in 1982 when two workers were killed in an industrial
accident. Since that time, EPA has completed four immediate removal actions to
respond to hazardous substances and waste stored in the waste oil lagoon,
storage tanks and drums, scrubber lagoon, and ash sludge piles. As a result of
these actions, there no longer are surface waste sources at the site. However,
waste sample jars and old equipment and containers do remain at the site. The
on- and off-site soil and ground water in the upper aquifer is contaminated both
by organic and inorganic chemicals, including PCBs, lead, trichloroethylene,
benzene, toluene, and phenol.
In September 1983, the Michigan Department of Natural Resources (MDNR),
through a cooperative agreement with EPA, initiated the remedial
investigation/feasibility study (RI/FS). The final RI was completed in May
1987, the FS report was completed in August 1987, and the ROD was signed
September 30, 1987. EPA has identified approximately 850 potentially
responsible parties (PRPs) for the LDI site. Notice letters pursuant to CERCLA
have been sent to all known PRPs. EPA's National Enforcement Investigation
Center has compiled information received from PRPs into a draft transactional
data base. A PRP Steering Committee has been organized, and EPA is currently
negotiating with PRPs to have them conduct the remedial action.
Description of Site Work
The State lead RI investigated contamination of the soil and ground water.
Results indicated that on-site concentrations of the contaminants generally are
higher than off-site concentrations.
Although there are no current users of ground water downgradient from the
site, the effects of LDI on the bedrock aquifer also were investigated.
Potential sources of aquifer contamination included leaks from the injection
well, migration of contaminants from the surface reaching the aquifer through
a poorly sealed well, and natural causes. There is strong evidence that surface
contaminants have only a slight chance of migrating through an underlying clay
layer. The high levels of downgradient contaminants are not believed to
originate from the site; thus, the ROD only addresses upper aquifer
contamination.
265
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
The RI also included an endangerment assessment and exposure assessment.
Possible routes of exposure that pose health risks include direct contact with
soils and leachate, and ingestion of the ground water. In addition, there is
potential risk to the Clinton River due to acute or chronic contamination of the
organisms in the wetlands.
Description of Feasibility Study
The FS, completed by the State in August 1987, evaluated remedial treatment
and containment technologies. Remedial alternatives were developed from the
technologies that met the criteria of achieving response objectives, controlling
or treating the chemicals present at the site, being applicable to the site
conditions, and meeting performance, reliability, and implementability
standards. Seven alternatives were evaluated in detail:
(1) No action;
(2) On-site land disposal of equipment and debris,
construction of a slurry wall and impermeable cap
containment system, and an air-stripping ion
exchange ground-water extraction and treatment
system;
(3) Off-site disposal of equipment and debris at a
sanitary landfill, off-site land disposal of soil
at a Resource Conservation and Recovery Act (RCRA)
landfill, and installation of an activated carbon
ground-water extraction and treatment system;
(4) Off-site disposal of debris and equipment at a
sanitary landfill, on-site incineration of soil
and waste, and installation of an ultraviolet
ozonation, flocculation, and precipitation ground-
water extraction and treatment system;
(5) Off-site disposal of debris and equipment at a
sanitary landfill, vacuum extraction combined with
solidification and fixation of the soil and waste,
and air stripping and ion exchange ground-water
extraction and treatment;
(6) Off-site disposal of debris and equipment, on-site
biodegradation and solidification and fixation of
soil and waste, and biological ground-water
treatment with flocculation and precipitation; and
(7) On-site land disposal of the debris and equipment,
on-site solidification and fixation of the soil
and waste, on-site ground-water extraction and
treatment using air stripping and ion exchange
technology, and construction of a slurry wall and
impermeable cap system.

Progress Toward Implementing Superfund: Fiscal Year 1987
Major State and Federal applicable or relevant and appropriate requirements
(ARARs) included RCRA, the Occupational Safety and Health Act (OSHA), the Clean
Water Act (CWA) , and the Toxic Substances Control Act (TSCA) . State ARARs
included the Michigan Hazardous Waste Management Act, the Michigan Solid Waste
Act, the Michigan Air Pollution Act, and the Michigan Water Resources Commission
Act.
Community involvement at the site included public meetings held at regular
intervals throughout the RI/FS process. At the request of several PRPs, the
public comment period on the FS was extended. Community concerns at an August
1987 public meeting addressed the solidification and fixation process because
the short-term impacts from them may include toxic air emissions.
Description of Selected Remedy
The recommended remedy is Alternative 7. Other alternatives were
eliminated for not meeting the CERCLA preferences for treatment and the required
compliance with ARARs. The alternative chosen is the most cost-effective and
is designed to meet all ARARs. Hazardous substances in the soil will be
solidified to reduce their mobility and toxicity; however, they will not be
destroyed permanently. Accordingly, the site will be reviewed under CERCLA
section 121(c) every 5 years to ensure that the remedy continues to be
protective. The alternative chosen has been endorsed by the State.

ROSE TOWNSHIP DUMP SITE
OAKLAND COUNTY, MICHIGAN
HRS Score: 50.92 NPL Rank: 166
Background
The Rose Township Dump site covers 110 acres in a wetland area in rural
Rose Township, Oakland County, Michigan. After being farmed in the 1950s, the
site was used illegally as a dump. Operators placed an estimated 5,000 drums
on one portion of the site, contaminated other areas with lead battery sludges,
and discharged bulk waste onto the soil surface and into shallow pits.
In 1968, the Oakland County Health Department (OCHD) was notified of the
illegal dumping. Over the next several years, a number of legal actions were
unsuccessfully brought against the waste hauler and property owner. In 1979,
the Michigan Department of Natural Resources (MDNR) sampled drums and domestic
wells at the site. The results prompted the State Toxic Substance Control
Commission to declare an emergency and to remove more than 5,000 drums of
contaminants from the site. In 1980 and 1982, MDNR conducted hydrogeologic
studies of the site by installing monitoring wells and taking soil samples.'
These initial investigations indicated that organic chemical contamination
extended below the shallowest aquifer and that additional information was
necessary to define the extent of the contamination.
The site was placed on the NPL in 1982. In October 1982, EPA notified
seven potentially responsible parties (PRPs) of their potential liability and
of EPA's intent to conduct a remedial investigation/feasibility study (RI/FS)
at the site. Upon completion of the RI/FS in 1986, EPA issued special notice
letters to 29 PRPs and held an informational meeting with 11 PRP representatives
on July 17, 1987. The ROD was signed September 30, 1987. Negotiations have
been held and a good faith offer from the PRPs was due in late 1987.
Description of Site Work
The purpose of the RI was to assess site conditions, chemical contaminant
distribution, and environmental and health risks at the site. Results of the
RI indicated that ground water, surface soils, and adjacent wetlands were
contaminated. Contaminants of concern found on the site were lead, zinc,' PCBs,
and volatile and semi-volatile organic compounds (VOCs). Ground water was
contaminated with several metals, including lead, iron, and zinc, and sampling
results identified two ground-water contamination plumes containing vinyl
chloride, xylene, toluene, and benzene. The principal threat to surrounding
communities is from potential contamination of nearby wells, the nearest of
which is 1,600 feet from the site. Although access to the site is restricted,
hunters, snow mobile riders, and the abundant wildlife on site are at risk from
potential exposure to high surface soil contamination. There is also a threat
to surrounding wetlands via drainage pathways.
268
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
The FS identified three specific areas of concern: ground-water plumes;
soil contamination; and drainage pathways to the wetlands. Following an initial
screening, five remedial alternatives were compiled:
(1) No action, except for monitoring;
(2) Excavation of contaminated soils, with off-site
land disposal;
(3) Excavation, with on-site thermal destruction of
organics and on-site disposal of ash;
(4) Excavation, with soil aeration to remove VOCs and
off-site land disposal of metals and PCBs; and
(5) Impermeable capping of site with in-situ vacuum
extraction of VOCs.
Each remedial alternative included extraction and treatment of ground water by
air stripping and carbon absorption.
Major Federal and State applicable or relevant and appropriate requirements
(ARARs) identified for the site included: Maximum Contaminant Levels (MCLs) and
the proposed Maximum Contaminant Level Goals (MCLGs) for chlorobenzene under the
Safe Drinking Water Act (SDWA); substantive requirements of the Resource
Conservation and Recovery Act (RCRA) and Michigan Act 64 concerning treatment
and storage of contaminants on site; RCRA regulations concerning design,
construction, operation, and maintenance of incinerators; and Toxic Substance
Control Act (TSCA) requirements for disposal of PCB-contaminated soil.
A public comment period for the RI/FS began on June 29, 1987, and was
extended beyond its 30-day deadline to August 27, 1987, in response to public
request. A public meeting was held on July 1, 1987, to discuss the proposed
remedial plan. The public supported the remedy selected (discussed below).
Description of Selected Remedy
The preferred remedial action alternative consisted of soil excavation, on-
site thermal destruction of contaminants, ground-water extraction and treatment,
and site fencing and monitoring (Alternative 3). Of the alternatives
considered, only the selected remedy is expected to satisfy all ARARs and
provide for permanent destruction of contaminants. Contaminated soils will be
excavated and incinerated to remove the risk of direct contact and further
ground-water contamination. Existing contaminants will be removed from ground
water so that the aquifer will be of potential use for potable water in 6 to 10
years.
An infrared incinerator will be used in a pilot test to destroy
contaminants on site. This technology was chosen because it is demonstrated to
have destruction and removal efficiencies of 99.9999+ 0/0 for wastes with
269
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
elevated PCB concentration and to "fix" heavy metals into the resulting ash.
Also, it is estimated that the infrared unit will have lower associated costs
than a rotary kiln incinerator. If the resultant ash passes EP toxicity test,
it will be backfilled on site. If not, it will undergo further treatment before
burial.

FMC CORPORATION
GROUND-WATER OPERABLE UNIT
FRIDLEY, MINNESOTA
HRS Score: 65.50 NPL Rank: 17
Background
The FMC site is located in Fridley, Minnesota, just north of Minneapolis.
The site lies approximately 1,000 feet east of the Mississippi River, one-half
mile upstream from Minneapolis' drinking water intake, which serves about
500,000 people. The site is divided into several sections, including the 13-
acre FMC lands and the 5-acre Burlington Northern Railroad (BNR) lands. Both
are located immediately south of the FMC Ordnance manufacturing complex. The
Naval Industrial Reserve Ordnance Plant (NIROP) is located directly north of the
FMC and BNR lands.
From 1941 to 1964, Northern Ordnance, Inc., operated a naval ordnance
manufacturing complex, later purchased by FMC. From approximately 1945 to 1969,
the FMC and BNR lands south of the complex were used for the incineration and
disposal of paint, oils, solvents, and other substances. In 1980, the Minnesota
Pollution Control Agency (MPCA) received a complaint regarding past disposal at
the BNR lands. MPCA required FMC to investigate both the FMC and BNR lands.
The FMC investigation revealed that past disposal had resulted in contamination
of ground water and of the Mississippi River.
The FMC site was proposed for inclusion on the NPL in 1982. Under a 1983
Consent Order with EPA, FMC excavated and contained contaminated soil and
initiated a remedial investigation/feasibility study (RI/FS) to evaluate
alternatives for a ground-water remedy. The final FS for the ground-water
operable unit was completed in 1985, and the ROD was signed September 30, 1987.
The U.S. Department of the Navy is conducting a separate RI/FS to address the
NIROP manufacturing facility and surrounding area.
Description of Site Work
The RI indicated that ground water beneath the FMC and BNR lands is
contaminated with trichloroethylene (TCE), benzene, toluene, and other volatile
organic compounds (VOCs) . Because ground water at the site discharges into the
Mississippi River, consumers of drinking water that flows through the
Minneapolis intake could be exposed to an increased health risk. Although
ground water in the contaminated areas currently is not used as a source for
drinking water, the long-term risk of exposure through the potential use of
private wells is a matter of concern.
Data derived from samples taken at the Minneapolis water intake on the
river indicated that TCE contamination, some of which can be traced to the FMC
and BNR lands, threatens to exceed the Maximum Contaminant Level (MCL) for TCE,
as established by the Safe Drinking Water Act (SDWA).
271
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
The purpose of the FS was to identify a remedial alternative that would
minimize potential ingestion of contaminants directly from ground water or from
the Mississippi River. The objective of the proposed response action was to
keep the health risk at any existing receptor under 10~6 additional lifetime
cancer deaths. The following remedial alternatives were formulated:
(1) No action;
(2) Long-term monitoring;
(3) Excavation and off-site disposal or on-site
containment;
(4) Capping;
(5) Physical containment via barrier wall and pumping;
(6) Hydraulic containment of ground water;
(7) Ground-water treatment and/or disposal;
(8) Alternative water supply; and
(9) In-situ biological treatment.
Applicable or relevant and appropriate requirements (ARARs) identified for
this operable unit included Federal and State drinking water standards,
particularly Federal MCLs and levels set forth by the State of Minnesota. The
discharge of treated water may be subject to requirements of the National
Pollutant Discharge and Elimination System (NPDES) program and the Clean Water
Act (CWA). Treatment involving air emissions may be subject to standards of the
Clean Air Act (CAA) and relevant State requirements.
Since 1983, State officials have kept local public officials informed of
events at and proposals for the FMC site. State officials discussed findings
of the RI/FS in meetings held in December 1985 and October 1986. Additionally,
in October 1986, the proposed Consent Order and plan for remedial action were
presented to the public for comment. The proposed remedy (discussed below) has
the broad support of the public and local government officials.
Description of Selected Remedy
EPA's recommended solution is a hybrid approach that combines hydraulic
containment through extraction wells (Alternative 6), discharge of untreated
ground water to a publicly-owned treatment works facility (Alternative 7), and
long-term monitoring (Alternative 2) . The enforcement of existing institutional
controls will ensure that ground water is not used in areas between the site and
the Mississippi River while the extraction system is operating.
272
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Five wells will be used to pump water from the site's aquifers. Upon
implementation, the extraction system will prevent migration of the contaminant
plume from FMC and BNR lands. Extracted ground water will flow to a publicly-
owned treatment facility. The effectiveness of this pump-and-treat system will
be assessed through monitoring of receptors, ground-water levels, contaminant
concentrations, and rates of discharge.
EPA believes that this alternative approach for the ground-water operable
unit will provide a permanent solution to contamination at the FMC site. The
operable unit deals strictly with the FMC and BNR lands and is expected to serve
as a permanent remedy for contaminated ground water in these areas. EPA also
believes that the remedy's expected attainment of State and Federal ARARs and
its monitoring phase will ensure long-term effectiveness in protecting public
health and the environment.

NEW BRIGHTON/ARDEN HILLS/ST. ANTHONY SITE
ST. ANTHONY OPERABLE UNIT
ST. ANTHONY, MINNESOTA
HRS Score: 59.16 NPL Rank: 39
Background
The New Brighton/Arden Hills/St. Anthony site is located immediately north
of Minneapolis and St. Paul, Minnesota, in the adjacent communities of New
Brighton, Arden Hills, and St. Anthony. The site consists of more than 18
square miles of ground water contaminated with volatile organic compounds
(VOCs) .
Approximately 75 to 80 percent of all Twin City communities that use ground
water for drinking water receive it from the Prairie du Chien-Jordan aquifer
system. In June 1981, the Minnesota Pollution Control Agency (MPCA) and the
Minnesota Department of Health (MDH) detected volatile organic solvent
contamination in the Prairie du Chien/Jordan aquifer system used for drinking
water in New Brighton. The nearby City of St. Anthony subsequently detected VOC
contamination in its three Prairie du Chien/Jordan aquifer wells.
In cooperation with EPA, the State conducted a preliminary Remedial
Investigation (RI) of the site in 1983. Because the RI did not provide
sufficient information on the contamination in the St. Anthony area, a further
RI is being conducted. To provide sources of drinking water for affected
residents in St. Anthony until the final remedial response is selected, EPA
completed a Phased Feasibility Study (PFS). The resulting ROD for the St.
Anthony operable unit was signed March 31, 1987. The final response action will
be recommended in a subsequent ROD when the RI/FS is completed.
Federal and State enforcement activities identified more than ten
potentially responsible parties (PRPs) that conducted some activity at either
of the two major source areas: the Twin Cities Army Ammunition Plant (TCAAP) and
a petroleum refinery. However, because none of the PRPs was willing to
participate at that time, EPA and MPCA proceeded with funding and undertaking
of remedial activities.
Description of Site Work
In 1983, the MPCA and EPA entered into a State lead cooperative agreement
for conducting the RI to determine the extent and source of contamination.
Trichloroethylene (TCE) , the most prevalent VOC, was used as the indicator
chemical. Preliminary results of the RI indicated two plumes of contaminated
ground water in the site area.
The source of the plumes appeared to be several areas in the vicinity of
the TCAAP. In wells in both New Brighton and St. Anthony, levels of TCE exceeded
EPA proposed Maximum Contaminant Level (MCL) for the protection of human health
from contaminants in drinking water. In response to the contamination, the City
of New Brighton closed down its six Prairie du Chien-Jordan aquifer wells and
tapped into a deeper aquifer.
274
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
The RI provided little information on the extent of contamination in the
plumes in the St. Anthony area. To provide more information on the extent of
the contamination, EPA and the State initiated a subsequent RI/FS. The MPCA is
planning to complete the remaining tasks of the comprehensive RI in 1988-1989
in order to evaluate potential final remedial actions. The U.S. Army, the owner
of TCAAP, has agreed in a Federal Facilities Agreement to do a comprehensive FS
for the entire site area upon completion of the EPA and State RI. The U.S.
Army, however, does not feel at this time that there is sufficient information
to place responsibility for the St. Anthony area contamination on the TCAAP.
While the RI was being completed, several initial remedial measures (IRMs)
were taken to provide drinking water for affected residents. The EPA lead IRM
in 1983 involved installing granular activated carbon (GAG) filters in two wells
in New Brighton. The State carried out an IRM to connect private well users in
New Brighton to water mains. In 1984, the State conducted an IRM to temporarily
connect St. Anthony's water supply to the City of Roseville.
Description of Feasibility Study
The primary objective of the St. Anthony operable unit PFS was to provide
safe, potable water to consumers who were dependent upon St. Anthony's municipal
wells. The PFS addressed separately the two primary municipal wells and the
emergency/standby well. For the two municipal wells, three alternatives passed
the initial screening:
(1) Connecting the St. Anthony wells to the Roseville/St. Paul
system;
(2) Treating wells using air stripping process; and
(3) Treating wells using GAG adsorption.
Similar alternatives were developed for the emergency/standby well.
The alternatives were initially proposed before the passage of SARA and
were subsequently reevaluated. Under CERCLA, the remedy must attain applicable
or relevant and appropriate requirements (ARARs). Primary ARARs for this site
were the MCLs set under the Safe Drinking Water Act (SDWA). The PFS assumed
that certain MCLs, which only were proposed when the study was completed, would
be final by June 1987.
Community response was considered a primary criterion in determining which
of the three alternatives to recommend. The EPA presented results of the PFS
at a public meeting and recommended construction of GAG water treatment
facilities. Following public comment, the recommended alternative was amended
to include the construction of a pipeline connecting the emergency/standby well
to the treatment facility.
275
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Selected Remedy
The selected remedy (Alternative 3) consisted of treating two of the St.
Anthony wells at a centralized location using GAG adsorption, and constructing
a transmission line from the emergency well to the proposed central treatment
facility. This remedy is the most cost-effective alternative and is expected
to significantly and permanently reduce the volume of the contaminants of
concern. Additionally, this alternative is expected to attain the ARARs at the
site. To the extent practicable, the operable unit will contribute to the
efficient performance of any long-term remedial actions.

NEW BRIGHTON/ARDEN HILLS/ST. ANTHONY SITE
TWIN CITIES ARMY AMMUNITION PLANT OPERABLE UNIT
NEW BRIGHTON, MINNESOTA
HRS Score: 59.16 NPL Rank: 39
Background
The New Brighton/Arden Hills/St. Anthony site is located in Ramsey County,
Minnesota, north of Minneapolis and St. Paul. The site consists of more than
18 square miles of ground water contaminated with volatile organic compounds
(VOCs). The Twin Cities Army Ammunition Plant (TCAAP) is located at the
northern edge of the NPL site.
In June 1981, the Minnesota Pollution Control Agency (MPCA) and the
Minnesota Department of Health (MDH) detected volatile organic solvent
contamination in the Prairie du Chien/Jordan aquifer system. Approximately 75
to 80 percent of all Twin City communities that use ground water for drinking
water receive it from the Prairie du Chien/Jordan aquifer system. The State
conducted several initial remedial measures to provide drinking water to the
affected communities and private well users.
In 1983, in cooperation with EPA, the State conducted a preliminary
Remedial Investigation (RI) of the site. For the purpose of providing drinking
water to different communities, the site was separated into several operable
units. A ROD for the fourth operable unit was signed in June 1986 to provide
New Brighton with an additional deep well. The ROD for the fifth operable unit
was signed in March 1987 to provide carbon treatment for two wells in St.
Anthony.
Federal and State enforcement activities identified the TCAAP as a major
source of VOC contamination in both the Hillside Sand Aquifer and the deeper
Prairie du Chien/Jordan Aquifer. Preventing migration of the VOC contamination
plume was designated as the sixth operable unit of the site. In June 1987, the
U.S. Army submitted its final proposal for construction of a gradient control
system to intercept the contamination plume. The EPA concurred with this remedy
in a ROD signed on September 25, 1987. Independent of this operable unit, the
U.S. Army, EPA, and MPCA entered into a Federal Facilities Agreement.
The plume interception system is an interim remedial action. The MPCA,
will complete an RI for the portion of the site outside of the Army plant
boundaries that was originally started in 1983 with funding provided by a
Cooperative Agreement between EPA and MPCA. The Army will conduct the on-site
TCAAP RI and area-wide (on- and off-plant) Feasibility Study (FS). Upon
completion of the RI/FS, EPA will evaluate potential final remedial actions in
accordance with section 120 of CERCLA.
Description of Site Work
The ongoing RI conducted by EPA and MPCA and subsequent investigations
indicated the TCAAP as a primary source of contamination. The U.S. Army has
estimated that approximately 26 pounds per day of VOCs were migrating from TCAAP
into the ground water of the Hillside Sand aquifer and the Prairie du
277
-------
Progress Toward Implementing Super-fund: Fiscal Year 1987
Chien/Jordan aquifer. Monitoring wells downgradient from the site showed VOC
levels in excess of 40 ppm. The current MPCA study cannot determine if the
plume of contamination extended beyond the New Brighton municipal well to the
nearby city wells of St. Anthony. The pathway of greatest concern was through
ingestion of drinking water.
Description of Feasibility Study
The U.S. Army document Ground-water Remedial Action Alternative Analysis considered
three alternatives for preventing migration of contamination:
(1) Source removal and no action for the migrating
contaminated water;
(2) Mechanical barriers -- source control and
containment slurry walls, pumping wells, and
capping; and
(3) Ground-water extraction system (referred to as the
Boundary Ground-water Recovery System)
hydraulic barriers with or without source removal
and control.
The ROD does not provide details of the screening criteria used to evaluate
these alternatives. Action-specific and contaminant-specific applicable or
relevant and appropriate requirements (ARARs) pertinent to the selected remedy
are discussed below.
EPA received numerous written and oral comments during the comment period.
The primary concerns expressed at a public meeting were the delay in cleaning
up the site, the possible health impacts, and the fact that the selected remedy
is not a final solution. The public believed that the U.S. Army attempted to
conceal the problem and avoid responsibility.
Description of Selected Remedy
EPA decided (and the U.S. Army concurred) upon the Boundary Ground-water
Recovery System (Alternative 3) as the interim remedy. Ground water will be
pumped from six previous Army-constructed wells, treated by air stripping, and
reinjected into the aquifer via an infiltration basin. Water treated at the
treatment facility is expected to meet Federal and State standards for drinking
water, e.g., a cumulative risk-based criteria of 10"6 for carcinogens. The Army
estimates that the system will stop 90 percent of the migrating VOCs. Based on
information gathered during the first 90 days of pumping, EPA will determine if
the existing well system is adequate for the protection of the aquifer.
The selected alternative is protective of human health and the environment,
but, because it does not address the source of contamination, it is not a
permanent remedy, it does not reduce mobility, volume, or toxicity of the
hazardous constituents, and it does not use treatment to the maximum extent
practicable. The interim remedy is, however, expected to attain ARARs.
Contaminant-specific ARARs for operation of the air stripper include the Clean
278

INDUSTRIAL EXCESS LANDFILL SITE
ALTERNATE WATER SUPPLY OPERABLE UNIT
UNIONTOWN, OHIO
HRS Score: 51.13 NPL Rank: 164
Background
The Industrial Excess Landfill (IEL) site is a closed sanitary landfill in
the unincorporated town of Uniontown in northeastern Ohio. Although the site
currently has a soil cover and vegetation, solid waste material is believed to
lie under approximately 80 percent of the site. There are over 400 residential
homes located within a 1/2 mile radius of the site.
From 1968 to 1980, the site was operated as a landfill for the disposal of
municipal, commercial, industrial, and chemical wastes. In 1980, due to public
concern and the fact that the landfill was reaching its capacity, the landfill
was closed and covered. Complaints by residents prompted investigations of
ground-water contamination because private wells were the source of drinking
water for nearby residents.
In October 1984, the site was included on the NPL. The remedial
investigation/feasibility study (RI/FS) was initiated in December 1984. EPA
implemented interim emergency actions and conducted a Focused Feasibility Study
(FFS) in August 1987 for the provision of safe drinking water. The ROD for the
alternative water supply operable unit was signed September 30, 1987. EPA is
continuing to develop a comprehensive RI/FS for a cleanup of the site, In April
1985, notice letters were sent to potentially responsible parties (PRPs), the
owner/operator of IEL and several tire companies who were generators of the
wastes. Negotiations did not produce a settlement and EPA took the lead in the
cleanup. After the FFS was released for public comments, EPA issued special
notice letters to PRPs concerning the implementation of the FFS.
Description of Site Work
The EPA lead RI indicated that some of the residential wells were
contaminated with organic substances (vinyl chloride and chloroethane) and
inorganic contaminants (barium, copper, cadmium, and nickel) that were
attributable to the landfill. In addition, organic and inorganic substances
were detected in the shallow wells near the border of the site. A risk
assessment concluded that short-term and long-term consumption of ground water
from contaminated residential wells may result in unacceptable health risks.
Description of Feasibility Study
Following emergency actions at the site, EPA initiated an FFS in August
1987. The major objective of the FFS was to provide a supply of safe drinking
water to residents whose ground water was contaminated or has the potential for
being contaminated. Four of eleven alternatives passed an initial screening
based on effectiveness, implementability, and cost:
(1) No action;
280
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
(2) Construction of a new community well supply "into
the Pottsville Group aquifers upgradient from the
site;
(3) Connection to the Village of Lakemore water system; and
(4) Connection to the City of North Canton water
system.
Alternatives were evaluated based on their ability to protect public health
and the environment and to meet applicable or relevant and appropriate
requirements (ARARs). ARARs for drinking water were identified as the Safe
Drinking Water Act (SDWA) Maximum Contaminant Levels (MCLs), Maximum Contaminant
Level Goals (MCLGs), and Ambient Water Quality Criteria (AWQC) adjusted for
drinking water for vinyl chloride. For arsenic contamination, the ARARs were
MCLs and the AWQC. For barium in the drinking water, the ARARs included MCLs,
an Ohio EPA standard, and MCLGs. Because they involved an alternate water
supply, none of the alternatives addressed reduction of the toxicity, mobility,
or persistence of contaminants. The four alternatives provide long-term
effectiveness by replacing the water supply.
Community involvement in the IEL site has been extensive. For example, 200
to 300 residents, the news media, and public officials attended a meeting in
August 1987 following the issuance of the FFS. Many of the comments received
during the public comment period were requests that EPA expand the area
receiving the alternate water supply, and that sources other than that specified
in the chosen remedy be considered.
Description of Recommended Remedy
The recommended remedy (Alternative 3) was the connection of approximately
100 homes to an alternate water supply, specifically, to the Village of Lakemore
water system. The chosen remedial action is cost-effective, is a permanent
remedy, and is expected to meet the ARARs identified; however, due to citizen
concerns regarding water quality and capacity, EPA has deferred the decision on
the alternate source of water. EPA issued a supplement to the ROD in December
1987, in which the water source was selected to be Country Club Village in
Summit County.

LASKIN/POPLAR OIL SITE
SOURCE MATERIAL OPERABLE UNIT
ASHTABULA COUNTY, OHIO
HRS Score: 35.95 NPL Rank: 492
Background
The Laskin/Poplar Oil site is located west of the village of Jefferson in
Ashtabula County, Ohio. The 9-acre site is bounded by Cemetery Creek and the
Ashtabula Fairgrounds. The site was formerly used for a greenhouse operation
beginning in the 1930s. Boilers were installed to heat the greenhouses in the
1950s, and tanks to hold waste oil for burning were built in the 1960s. When
the greenhouse business declined, the owner of the site began collecting,
reselling, and disposing of waste oils, much of which contained PCBs and other
hazardous materials.
The State of Ohio initiated action against the site owner in 1979 for air
and water pollution violations. In late 1980, EPA evaluated the need for
remedial action at the site and in 1982 undertook an emergency action, which
included removing 302,000 gallons of oil, treating 430,000 gallons of
contaminated water, and solidifying 205,000 gallons of sludge. Potentially
responsible parties (PRPs) removed another 250,000 gallons of oil wastewater in
1985 and 1986. EPA issued an Administrative Order of Consent to 12 PRPs between
1984 and 1986, requiring their participation in the remediation process.
EPA divided remedial activities at the site into two operable units and an
overall site investigation. The first operable unit addressed the incineration
of contaminated water and PCB-contaminated oils. The ROD for the second
operable unit, which focused on source material that remained on site, was
signed September 30, 1987. The overall site investigation still is being
conducted and will address ground water, surface water, and soil contamination
as well as the extent of dioxin contamination.
Description of Site Work
When the overall RI was initiated, the site contained 34 tanks, 4 pits, and
treatment and retention ponds. Preliminary sampling indicated large amounts of
seepage from tanks and unlined pits into surrounding soils. Investigations also
identified a threat from contaminants leaching into ground and surface water,
including Cemetery Creek, which runs into the Grand River, a source of drinking
water for 25,000 residents.
Potentially responsible parties, under Consent Order, initiated the study
for the second operable unit in 1985 to characterize the remaining on-site
wastes. Results indicated that waste materials still present at the site after
emergency removal actions posed a serious threat to human health and the
environment through the threat of fire and exposure to PCBs. Major contaminants
of concern at the site are PCBs, polynuclear aromatic hydrocarbons (PAHs), and
volatile organic compounds (VOCs), all of which were present in high
concentrations in waste oil and surrounding soils.
282
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
The Phased Feasibility Study (PFS) for the second operable unit evaluated
remedial alternatives for the removal of source materials, including sludges,
waste oils, wastewaters, and contaminated soils (included in this operable unit
because they were a source of potential contamination of ground and surface
water). All attempts were made during the PFS to ensure that the alternatives
developed for this operable unit were consistent with final remediation for the
site. Remedial alternatives developed, in addition to a "no action"
alternative, included:
(1) Solidification of all liquid wastes and disposal
in licensed waste disposal facilities;
(2) On-site incineration of oils, sludges, and soils,
with off-site treatment of wastewaters;
(3) Off-site incineration of oils, sludges, and soils
and off-site treatment of wastewaters; and
(4) On-site incineration of oils, sludges, and soils
that contained PCBs at concentrations greater than
25 parts per million (ppm) or halogenated organics
at concentrations in excess of 500 ppm;
landfilling of the remaining oils, sludges, and
soils; and off-site treatment of wastewaters.
The PFS identified the Federal and State applicable or relevant and appropriate
requirements (ARARs) that the remedial action must meet, consistent with the
requirements of CERCLA. One technology considered for use on the site was on-
site containment of the wastes. However, because the Resource Conservation and
Recovery Act (RCRA) land disposal restrictions were considered ARARs, this
option was not considered further. Other ARARs identified for this site
included RCRA thermal destruction, incinerator, and off-site transportation
regulations; Ohio Clean Air Act limits on incinerator emissions; and Ohio
regulations for the off-site transportation of hazardous waste.
Public comment on the RI/FS was received during a public availability-
session, a public meeting, and through written comments. Residents and local
officials supported the selected remedy discussed below.
Description of Selected Remedy
The remedy selected was on-site incineration of all oils, sludges, and
contaminated soils and the off-site treatment of contaminated waters
(Alternative 2). This alternative uses a proven technology (i.e., inciner-
ation), and, because contaminated materials are destroyed it satisfies CERCLA1s
preference for permanent solutions and use of treatment technologies. The
remedy also does not involve the off-site transportation of hazardous materials
(i.e., the oils, sludges, and contaminated soils) before treatment; when
implemented, it will provide a high level of protection of human health and the
environment. The remedy is also expected to meet all ARARs for this operable

unit. The State of Ohio was consulted during the remedy selection process and
concurred with the chosen alternative.

NORTHERN ENGRAVING CORPORATION SITE
SPARTA, WISCONSIN
HRS Score: 38.75 NPL Rank: 414
Background
The Northern Engraving Company (NEC) site is located in Sparta, Wisconsin,
23 miles east of LaCrosse, and is bordered on the south by the LaCrosse River.
Areas of the river's floodplain lie within the site area, and a city well is
4,000 feet from the NEC site. The site includes a manufacturing facility that
produces metal name plates and dials for the automobile industry. The
manufacturing process involves metal finishing operations that include
anodizing, chemical etching, and chromate conversion coating. During the 1970s,
NEC discharged rinse water to the on-site sludge lagoon to allow the metal
hydroxides to settle, and effluent from the lagoon ran along a drainage ditch
to the LaCrosse River. By 1980, 2 to 4 feet of metal hydroxide sludge had
accumulated in the lagoon. On several occasions, sludge was removed and
landfilled on site. NEC also used a seepage pit to dispose of rinses and dye
solutions.
EPA investigations of the NEC site resulted in its placement on the NPL in
September 1983 and the identification of NEC as the potentially responsible
party (PRP). Under a Consent Order with EPA, NEC initiated a remedial
investigation/feasibility study (RI/FS) in September 1985. EPA signed the ROD
September 28, 1987.
Description of Site Work
The RI conducted by NEC identified four separate areas as potential
sources of soil, ground-water, and surface-water contamination: the sludge
lagoon, seepage pit, sludge dump site, and lagoon drainage ditch. The sludge
lagoon was contaminated primarily with metal hydroxides. The drainage ditch had
elevated levels of fluoride, aluminum, chromium, and copper. On two occasions
the sludge dump, now backfilled, received contaminated sludge from the lagoon
which totals approximately 930 cubic yards. Metal hydroxides found in the
lagoon are evident in the sludge dump. Ground-water monitoring within and
downgradient from the seepage pit detected trace amounts of volatile organic
compounds (VOCs) and elevated amounts of heavy metals. However, because no
wells were threatened by contamination and the dilution caused by the LaCrosse
River, ground-water contamination was considered to present no exposure risk.
The LaCrosse River water exhibited no contaminants at concentrations exceeding
any surface-water criteria except for zinc which was shown to meet the chronic
toxicity water quality criteria. Thus, the RI concluded that the site presented
few environmental or public health threats. The only considerable potential
human health risks were from direct contact with soils in the drainage ditch and
contaminated sludge in the sludge lagoon, and possible ingestion of contaminated
ground water.
285

The
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
The FS for the site, conducted by NEC under EPA's supervision, evaluated
remedies for each discrete waste unit. Because the site appeared to present
little endangerment to the environment or public health, the remedial action
objectives emphasized the minimization of long-term contact with contaminated
soil and the prevention of ingestion of the contaminated water. Potential
remedial alternatives were screened against the CERCLA criteria of long-term
effectiveness, implementability, and cost, and consideration was given to
treatment technologies that permanently reduce toxicity, mobility, or volume of
the waste.
following remedies proposed for each area passed the initial screening:
(1) Sludge Lagoon:
• No action;
• Capping lagoon;
• Solidification of sludge and capping of lagoon;
• Excavation and off-site disposal of sludge and pumping
and treating of ground water;
• Excavation and off-site disposal of sludge and soil and
pumping and treating of ground water; and
• Excavation and off-site disposal of sludge arid
monitoring of ground water.
(2) Drainage Ditch:
• No action;
• Access restriction through installation of a fence;
• Excavation of contaminated drainage ditch soil and
placement in sludge lagoon; and
• Excavation of contaminated drainage ditch soil and off-
site disposal.
(3) Sludge Dump:
• No action;
• Capping of dump site;
• Excavation of sludge for off-site disposal; and
• Excavation of sludge and soil for off-site disposal;
and
• Excavation of sludge and solidification in sludge
lagoon.
(4) Seepage Pit:
• No action;
• Excavation of soil for off-site disposal;
• Access restrictions and ground-water monitoring; and
• Monitoring excavation of soil for off-site disposal,
and pumping and treating of ground water.
The major applicable or relevant and appropriate requirements (ARARs)
identified for the NEC site were Resource Conservation and Recovery Act (RCRA)
closure and post-closure requirements, the Clean Water Act (CWA), Wisconsin
286
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
State closure and post-closure requirements, and State Ground-Water Protection
Laws.
The NEC site generated little public interest since being identified as a
Superfund site. The public made no comments on the RI/FS or Consent Order and
no party expressed any interest in holding a public meeting.
Description of Selected Remedy
The selected remedy comprises three components: source control, migration
management, and operation and maintenance. For source control, contaminated
materials from the drainage ditch and sludge dump will be excavated and placed
in the sludge lagoon for solidification. After solidification, the sludge
lagoon will be provided with a RCRA cover and monitored for proper closure.
Deed restrictions and long-term monitoring will be implemented for the seepage
pit. Migration management consists of monitoring contaminated water through the
application of alternative concentration limits (ACLs) downgradient from the
sludge lagoon and the seepage pit. For operation and maintenance, the cover
over the sludge lagoon and the seepage pit will routinely be inspected and
monitored. Semi-annual ground-water sampling and analyses at compliance
monitoring wells will also be conducted.
The statutory emphasis on treatment and long-term effectiveness is
fulfilled through the use of solidification. The long-term effectiveness of
RCRA caps placed over the sludge dump and seepage pit can be ensured only as
long as monitoring continues. The remedy reduces the mobility of the
contaminants, but does not reduce their volume or toxicity. The selected
treatment is expected to attain ARARs.

SCHMALZ DUMP SITE
SECOND OPERABLE UNIT
HARRISON, WISCONSIN
HRS Score: 48.92 NPL Rank: 190
Background
The Schmalz Dump site is located on the north shore of Lake Winnebago in
Harrison, Wisconsin, 90 miles north of Milwaukee. The site consists of 7 acres
of wetlands that since 1968 were used as a waste dump for solid waste, car
bodies, pulp chips, and other materials. Between 1972 and 1973, Gerald Schmalz,
the former owner of the site, accepted fly ash and bottom ash from Menasha
Utility. In 1978 and 1979, Schmalz accepted the demolition debris of a building
owned by the Allis-Chalmers Corporation. EPA suspects that these wastes are
sources of present contamination at the site.
The Wisconsin Department of Natural Resources (WDNR) and the U.S. Army
Corps of Engineers conducted on-site soil sampling in early 1979 and found high
concentrations of PCBs in the area of the Allis-Chalmers debris, as well as lead
and chromium throughout the site. In 1979, the State sued Mr. Schmalz, the
waste hauler, and Allis-Chalmers for illegal PCB-disposal, but lost the case
because of lack of evidence. Mr. Schmalz sold the dump to his son in 1983.
In September 1984, the site was placed on the NPL. The EPA lead remedial
investigation/feasibility study (RI/FS) was initiated during April 1985.
Because of the immediate health threat presented by the PCB-contaminated debris,
EPA and WDNR decided to designate an operable unit specifically to address this
contamination. The ROD for this operable unit was signed in August 1985 and
called for removal of PCB-contaminated debris and sediments. The RI/FS for
remediation of the rest of the site has progressed concurrently with the design
of the PCB contamination operable unit remedy. The RI for the entire site was
completed in June 1987. The FS report was finalized in August 1987 and the ROD
signed September 30, 1987.
Eight potentially responsible parties (PRPs) were identified for the site.
Notice letters were sent and a negotiating meeting held to discuss the RI/FS,
but none of the parties committed to perform the RI/FS.
Description of Site Work
The objective of the RI for the entire site was to characterize the areas
of the site that were not addressed by the PCB-contamination operable unit.
Results of the study indicated that lead and chromium were the contaminants of
concern at the site and that direct contact with surface and subsurface soil
were the exposure pathways of greatest risk. PCB contamination is confined to
the area in which demolition debris was disposed; EPA addressed this threat by
removing the debris during the PCB-contamination operable unit remedial action.
Although traces of chromium were found in ground water beneath the site,
EPA determined that this contamination did not pose a health threat because
levels were below Safe Drinking Water Act (SDWA) Maximum Contaminant Levels
(MCLs). Test results indicated that leaching of soils was not likely to
288
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
increase chromium and lead concentrations in the ground water to levels greater
than MCLs. However, the remote possibility exists that this pathway could
become a concern at a later time.
Description of Feasibility Study
The objectives of the FS for the rest of the site were to protect the
public from direct contact with contaminated soils, and to monitor for
degradation of ground-water quality from those soils. The FS developed the
following six alternatives to meet these objectives, all of which met initial
screening criteria and were retained for detailed analysis:
(1) Ground-water extraction; treatment of ground water with
coagulation/flocculation, filtration and ion exchange
to reduce contamination to background levels; and
discharge of the treated ground water to a nearby
stream;
(2) Construction of a slurry wall; placement of a soil,
gravel, and clay cap; and ground-water monitoring;
(3) Construction of a Resource Conservation and Recovery
Act (RCRA) Subtitle C compliant cap, and ground-water
monitoring;
(4) Construction of a low-permeability soil cover, and
ground-water monitoring;
(5) Excavation of contaminated soil,
solidification/stabilization of the soil, and
replacement with treated soil; and
(6) No action.
The following Federal applicable or relevant and appropriate requirements
(ARARs) were identified: SDWA MCLs; Clean Water Act (CWA) Ambient Water Quality
Standards; Water Quality Act of 1987 Great Lakes Protection requirements;
Executive Orders for Protection of Wetlands and Floodplain Management; and RCRA
clean closure and landfill closure requirements. State ARARs included ground-
water protection, shoreland management, and closure requirements.
During the public comment period, a local water-quality planning agency
and one private citizen expressed support for the RCRA compliant cap
alternative. The community does not perceive the site as an immediate danger,
although some residents are concerned about the potential for contamination of
the Appleton water supply. The State expressed support for alternatives that
involve capping of the site, but was concerned that the cap would not adequately
be protected from damage. The State will attempt to obtain a voluntary
agreement from the landowner not to damage the cap once it is installed. The
State is aware that EPA has the legal authority to order further corrective
action should the owner attempt to damage the cap.
289
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Selected Remedy
The remedy selected for the Schmalz Dump site (Alternative 4) included the
following actions: installation of a low-permeability soil cap over the
contaminated soil; implementation of a ground-water monitoring program and a
voluntary well abandonment program for residents; and a recommendation that
adjacent property be analyzed for contamination.
The selected remedy is the most cost-effective alternative, is expected to
attain ARARs, and adequately protects human health and the environment by
eliminating the threat of direct contact with contaminated soils. The remedy
does not reduce the toxicity of lead and chromium in soils or in the ground
water, and provides minimal protection for ground water. It will reduce the
mobility of contaminants in soil, however, and provide long-term protection of
soil.

BAYOU BONFOUCA SITE
SOIL CONTAMINATION OPERABLE UNIT
SLIDELL, LOUISIANA
HRS Score: 29.78 NPL Rank: 731
Background
The Bayou Bonfouca site is located about 7 miles north of Lake
Pontchartrain in Slidell, Louisiana, and has an area of about 55 acres. The
site is an abandoned and dismantled creosote works that is within the designated
100-year flood plain of the bayou. Land use to the east of the site is
primarily commercial, and to the southwest across the bayou is a residential
subdivision.
From 1892 to 1970, the facility was operated under the ownership of various
creosote companies, and is currently owned by the Braselman Corporation. During
its operating history, the facility has had numerous releases of creosote. The
primary contaminants are polynuclear aromatic hydrocarbons (PAH) that have been
found in the soils, surface-water deposits, ground water, and bayou and channel
sediments.
Numerous studies have been conducted to identify and determine the extent
of contamination at the site. An initial investigation in 1976 by the U.S.
Coast Guard was followed by a 1978 study conducted by EPA, the Coast Guard, and
the National Oceanic and Atmospheric Administration. Two potentially
responsible parties (PRPs) were identified: American Creosote Works, the last
wood treating company to operate the site, and Braselman Corporation, the
present owner. In 1981, the State of Louisiana rejected a cleanup proposal
proposed by Braselman Corporation, and the site was included on the NPL in
December 1982.
In 1983, EPA initiated a phased remedial investigation/feasibility study
(RI/FS) for Bayou Bonfouca. The first phase identified and estimated the
surface contaminants which resulted in a focused feasibility study (FFS). Based
on the FFS, a record of decision (ROD) was signed in August 1985 for the removal
and offsite disposal of contaminated materials. Due to further studies in the
second phase and changes in CERCLA as amended by SARA, off-site disposal was
never implemented. A new ROD for the Bayou Bonfouca site was issued in March
1987 as detailed in the following paragraphs. The final remedial investigation
report and feasibility reports were issued in April and June 1986, respectively.
Description of Site Work
The remedial investigations have identified that the contaminated areas
include a major portion of the south half of the site, Bayou and channel
sediments, and the surficial and shallow artesian aquifers. These studies
indicate that Bayou and channel contaminated sediments are estimated at
approximately 47,000 cubic yards.
291
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
The June 1986 FS identified remedial alternatives necessary to reduce or
eliminate the potential for ingestion of carcinogens in ground water, surface
soils, and shellfish; to control the migration of PAH contamination in the
aquifer; and to reduce or eliminate the direct contact threat posed by the
sediments and surficial waste.
After a final screening of alternatives, a total of nine treatment
alternatives for source control were considered:
(1) No action;
(2) Permanent diversion of the bayou with in-place
stabilization of bayou sediments with backfill and cap,
on-site landfill of creosote waste piles, and on-site
cap of soil;
(3) Bayou partition and on-site landfill of sediments, on-
site landfill of creosote waste piles, and on-site soil
cap;
(4) Alternative 3 with off-site landfill of sediments and
waste piles;
(5) Bayou partition and on-site incineration of sediment,
waste piles, and soil;
(6) Alternative 5 using a soil cap instead of incinerating
contaminated soil;
(7) Bayou partition and on-site biological treatment of
sediment, waste piles, and soil;
(8) Bayou partition and off-site landfarming of sediment,
waste piles, and soil; and
(9) Bayou partition and off-site incineration of sediment,
waste piles, and soil.
The eight remedial action alternatives included identical measures for
remediating ground-water contamination through use of slurry walls around the
site.
In July 1986, a public meeting was held in which citizens requested a 3-
month extension of the public comment period until October 31, 1986. During
this time SARA was signed and the proposed remedy for the site did not comply
with the provisions of the Act. Under CERCLA as amended, consideration of
alternatives must demonstrate a preference for permanent solutions, and all
remedial action must attain applicable or relevant and appropriate requirements
(ARARs). Several of the remedies considered in the June 1986 FS were permanent
solutions. The relevant ARARs identified and considered included Executive
292
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Orders 11988 and 11990 for Floodplain Management and Protection of Wetlands, the
Clean Water Act (CWA), and the Resource Conservation and Recovery Act (RCRA).
Description of Selected Remedy
The alternative recommended for the Bayou Bonfouca site (Alternative 6)
includes on-site incineration of the creosote waste deposits and contaminated
sediments in a mobile incinerator. The incinerator ash and contaminated soils
will be covered with a RCRA cap. Ground water will be remediated through a
pump-treat reinjection process.
This alternative is considered protective and cost-effective, is expected
to attain ARARs, and uses permanent solutions and treatment technologies to the
maximum extent practicable. The Louisiana Department of Environmental Quality
concurred with this remedy.

CLEVE REBER SITE
ASCENSION PARISH, LOUISIANA
HRS Score: 48.80 NPL Rank: 196
Background
The Cleve Reber site is located in Ascension Parish, Louisiana, between New
Orleans and Baton Rouge. The 25-acre site is bounded by swamps and semi-
developed agricultural and residential areas. Originally used as a borrow pit,
the site later became a disposal area for municipal and industrial waste between
1970 and 1974. Environmental Controls Company (ECC) , with Cleve Reber as
president, leased the property and operated a landfill before abandoning the
site in 1974.
After numerous site inspections and sampling efforts, the State of
Louisiana declared the area an abandoned hazardous waste site in October 1979.
Information provided by potentially responsible parties (PRPs) suggested that
6,400 drums of waste were buried on site. In response to public concern, EPA
conducted an emergency removal of 1,100 surface barrels and waste piles in 1983.
An EPA lead remedial investigation (RI) completed in May 1985 indicated
that the major concern is the Norco Aquifer, a surface-flowing artesian aquifer
that supplies fresh water to industrial and private consumers. Ground-water
samples collected in early June 1985 provided additional data for evaluating
remedial response. Due to lack of data, a supplemental remedial
investigation/feasibility study (RI/FS) was completed in September 1986, and the
ROD was signed March 31, 1987.
EPA has since issued notice letters to ECC, former owners of the property
and known generators of the hazardous waste. Several PRPs that identified
themselves as waste generators participated in the emergency removal and
expressed interest in participating in remedial actions.
Description of Site Work
Results of the initial RI indicated that industrial waste, consisting
partly of hazardous organic compounds, has migrated and mixed with the municipal
waste. Significant soil contamination has been detected on site, and studies
of ground water in the shallow sand layer beneath the site found elevated levels
of hexachlorobenzene (HCB), hexachloroethane (HCE), and hexachlorobutadiene
(HCBD). Because the contamination was detected in the shallow sand layer, an
additional RI/FS was undertaken to investigate ground-water contamination.
The primary hazards to human health were associated with ingestion of or
direct contact with surface soils, on-site surface water, on-site leachate, and
ground water. The RI found no contamination in the deep sand layer or in the
Norco Aquifer, and contamination appeared to be confined to the site.
294
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
The initial FS was completed in May 1985, and the supplemental RI/FS was
completed in September 1986. Although the original and supplemental RI/FSs
predated SARA, efforts were made to conform the supplemental study to the
anticipated statutory requirements for selecting permanent solutions and
treatment technologies to the maximum extent practicable.
Based on the criteria of effectiveness, implementability, cost, and ability
to meet applicable or relevant and appropriate requirements (ARARs), the
following remedial alternatives were considered:
(1) No action;
(2) Complete removal of all contaminated material with
disposal in an off-site landfill;
(3) Closure of the site with containment of all
contamination;
(4) Alternative 3 with on-site incineration or
disposition of all bulk sludges and materials in
drums;
(5) Alternative 3 with off-site incineration;
(6) Alternative 2 with off-site incineration; and
(7) Alternative 2 with on-site incineration.
ARARs identified in the supplemental FS included the Clean Water Act (CWA),
the Resource Conservation and Recovery Act (RCRA), Executive Orders for
Floodplain Management and Protection of Wetlands, and State laws. At the time
the ROD was signed, the State had not identified any ARARs other than those
identified by EPA.
EPA issued a press release on May 31, 1985, that described the site and
discussed EPA's proposed remedy. At that time, the proposed remedy was a cap-
in-place approach. Sampling results subsequently released prompted EPA to
postpone a decision on the remedy and commence a supplemental RI. After
identifying its preferred alternative (discussed below), EPA conducted another
public meeting in February 1987. Most people attending favored the selected
remedy.
Description of Selected Remedy
EPA recommended Alternative 4 as the approach for remediation of the Cleve
Reber site. Alternative 4 involves the on-site incineration of drummed wastes
and bulk sludges, the removal and backfilling of all ponds, and the use of a
RCRA cap over remaining contamination. The cap will cover only the area of the
site used for disposal of industrial or hazardous waste. The alternative will
295
-------
Progress Toward Implementing Superfuod: Fiscal Year 1987
involve removal of the source of ground-water contamination, thereby reducing
the future volume and mobility of the contaminants.
Residual contamination after the source removal will be attenuated by the
underlying organic clays. The site will be monitored for 30 years to guard
against the migration of contaminants. The alternative chosen is adequately
protective, cost-effective, is expected to comply with ARARs, and uses permanent
solutions and treatment technologies to the maximum extent practicable.
Description of Remedial Design
In September 1987, EPA and the contractor began the remedial design. In
February 1988, field work to gather additional information for the design began.
Trenching was performed to identify specific locations of buried drums and bulk
sludges. Leachate, pond water, and waste were sampled for additional testing.
Design specifications and contract documents are scheduled to be completed by
the spring of 1989.

COMPASS INDUSTRIES LANDFILL SITE
WEST TULSA, OKLAHOMA
HRS Score: 36.57 NPL Rank: 483
Background
The Compass Industries Landfill site is located in West Tulsa, Oklahoma
near the communities of Berryhill and Sand Springs. The site includes a 32-acre
landfill area and is situated on a bluff approximately 200 feet above the
Arkansas River. Surface water from precipitation runoff, springs, and seeps
flows into the River from the bluff through a network of small streams. The
site is underlain by two aquifers, neither of which is known to be used for
drinking water.
The site was initially used as a limestone quarry from the 1930s through
the 1950s. From 1972 to 1976, the site was permitted by the Oklahoma State
Department of Health (OSDH) as a municipal and industrial landfill, although
there is evidence that dumping occurred at the site as early as 1964. During
the 1970s, several fires were reported at the landfill. Following complaints
from residents about air emissions from the fires, the State and EPA
investigated the site. The site was listed on the NPL in September 1984.
EPA provided funding for a State lead Remedial Investigation (RI) in 1984
to determine the extent of ground- and surface-water contamination. The
remedial investigation/feasibility study (RI/FS) was completed in mid-1987 and
the ROD was signed September 29, 1987. Investigations have identified
approximately 20 potentially responsible parties (PRPs), but there has been no
documented involvement by PRPs in the remediation process.
Description of Site Work
The State lead RI identified surface runoff to the Arkansas River as the
most significant pathway of exposure. The RI identified 12 inorganic and 33
organic pollutants in the two aquifers beneath the site and in surrounding
soils. Although the upper aquifer on the site was highly contaminated, the
hydrogeology and topography of the site appeared to have minimized the migration
of the contaminated ground water.
Description of Feasibility Study
The State lead FS developed an initial set of remedial approaches for
limiting surface-water migration. Six alternatives were chosen for a full
evaluation against the criteria specified by CERCLA:
(1) No action;
(2) Capping and on-site ground-water treatment;
(3) Capping and off-site ground-water treatment;
(4) Complete on-site thermal destruction of landfilled
material;
297
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
(5) Partial on-site thermal destruction of landfilled
material and capping of soils; and
(6) Partial off-site thermal destruction of landfilled
material and capping of soils.
The FS also identified the applicable or relevant and appropriate
requirements (ARARs) that the remedial action must meet. Federal ARARs
identified for the site included Resource Conservation and Recovery Act (RCRA)
capping requirements, National Pollution Discharge and Elimination System
(NPDES) requirements, the Clean Water Act (CWA), the Fish and Wildlife
Coordination Act (FWCA), and the Endangered Species Act (ESA). State ARARs
identified included the Oklahoma Clean Air Act and Oklahoma Water Quality
Standards.
There was substantial public involvement during the RI/FS process. EPA
held a public meeting on August 18, 1987, to explain the remedy that was
proposed (discussed below) and to answer questions from the approximately 65
people in attendance. EPA also met with officials from Tulsa and the City of
Sand Springs in order to explain the proposed remedy.
Description of Selected Remedy
The remedy proposed during the public comment period and subsequently
selected was Alternative 2, a cap constructed to meet the specifications of RCRA
closure requirements and treatment of the upper, perched aquifer, if deemed
necessary following placement of the cap. Specifically, the remedy consisted
of site grading, placement of a cap over contaminated soils, diversion of
surface water from the site, monitoring of air emissions in case of further
fires, and installation of security fences and warning signs to restrict access
to the site. EPA decided to defer treatment of the upper, perched aquifer until
after placement of the RCRA cap and evaluation of the cap's effectiveness in
restricting or eliminating the surface-water discharges along the bluff.
This remedy is expected to be protective of human health and the
environment and uses permanent solutions and treatment technologies to the
maximum extent practicable. The remedy is also expected to attain all ARARs.
The State of Oklahoma was consulted during the FS, and concurred with the remedy
selected.

SAND SPRINGS PETROCHEMICAL COMPLEX SITE
SOURCE CONTROL OPERABLE UNIT
SAND SPRINGS, OKLAHOMA
HRS Score: 28.86 NPL Rank: 761
Background
The Sand Springs site is located in an industrial complex on the northern
bank of the Arkansas River in Sand Springs, Oklahoma, 5 miles west of Tulsa.
The site is the former location of the Sinclair oil refinery, which operated
from the turn of the century until 1949. The site encompasses approximately 235
acres and most of the property was conveyed to Sand Springs Home in 1953 to be
developed into an industrial area. In 1969, the remaining 38-acre tract of land
at the site was put under control of the Atlantic Richfield Company (ARCO) in
a merger with Sinclair.
Part of the site developed as an industrial area and was used by a solvent
recycling facility in the late 1960s and early 1970s. During this period,
hazardous substances were stored or disposed of in drums, tanks, unlined pits,
and lagoons, or buried on site. Sulfuric acid sludge pits from the former
refining operation are contaminated with heavy metals and organics.
Construction activities exposing part of one pit resulted in a release of fumes
that necessitated evacuation of a nearby factory, during which several people
required medical attention. Other waste pits have contaminated ground water
with volatile and non-volatile organics and chlorinated solvents. EPA
investigations in 1980 and 1982 revealed that lagoons and a surface impoundment
were also contaminated. A total of approximately 130,000 cubic yards of waste
are present at the site.
EPA proposed the site for the NPL in September 1983. In June 1984, the
Oklahoma State Department of Health (OSDH) agreed to conduct the remedial
investigation/feasibility study (RI/FS) using funds EPA provided. In an attempt
to address the most apparent contamination quickly, EPA established a source
control operable unit to focus on waste in the pits, ponds, and lagoons. OSDH
completed the source control operable unit RI/FS in April 1987, and the ROD was
signed September 29, 1987. The remainder of the site, including ground-water
contamination, was addressed In a final operable unit FS that was completed in
April 1988. A public meeting was held March 24, 1988. The proposed remedy is
no action (monitoring following the source control remedial action). The ROD
is expected to be signed in June 1988.
EPA has identified approximately 300 potentially responsible parties (PRPs)
for the site, two of which have taken actions at the site under administrative
orders.
Description of Site Work
During its source control RI, the OSDH sampled 11 waste disposal locations
on the Sand Springs site. Results indicated that all surface locations were
contaminated with inorganic and organic compounds. The priority pollutants
identified included lead, zinc, chromium, chrysene, phthalate, toluene, trans
1,2-dichloroethene, and tetrachloroethane. The source control RI also
299
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
identified three major risks to human health and the environment from the site:
direct contact with wastes; air emissions from the site; and surface-water
contamination due to runoff from the site during heavy rains.
Description of Feasibility Study
In order to mitigate the on-site soil, surface- water, and air
contamination, the OSDH developed five remedial alternatives, in addition to
the "no action" alternative:
(1) Excavation and on-site thermal destruction of
contaminated sludges and on-site disposal of residual
ash;
(2) Solidification of contaminated sludges and disposal in
an on-site landfill;
(3) Excavation and on-site neutralization, solvent-
extraction, and treatment of hazardous sludges, and
disposal of oil, water, and solid byproducts;
(4) Excavation and off-site thermal destruction of
contaminated sludges; and
(5) Excavation and off-site solvent-extraction treatment
of contaminated sludges.
Alternatives, which utilized any on-site disposal, also included construction
of a RCRA cap over the landfill area. Each alternative also included removal
and treatment of contaminated liquids.
The FS identified the following applicable or relevant and appropriate
requirements (ARARs) for the site: the Resource Conservation and Recovery Act
(RCRA); the Clean Air Act (CAA) National Ambient Air Quality Standards (NAAQS);
National Pollutant Discharge Elimination System (NPDES) requirements; the Clean
Water Act (CWA); Executive Order 11988 for Floodplains; the Fish and Wildlife
Coordination Act; and State solid waste, hazardous waste, clean air, and water
quality regulations.
The local community expressed concern about the construction of an
incinerator on site, particularly about potential air pollution from the
incinerator, potential decline in property values from its presence, and whether
the incinerator would be removed after cleanup. At least 180 people attended
the public meeting held to discuss the source control RI/FS results, during
which EPA agreed to extend the public comment period.
300
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Selected Remedy
After detailed analysis of the alternatives, EPA proposed the on-site
thermal destruction as the source control alternative best satisfying statutory
criteria, although this remedy was costly and neither the State or the local
community preferred it.
During the public comment period, ARCO, as a PRP, made a proposal for a
privately financed remedy for the site that did not include construction of an
on-site incinerator. EPA evaluated ARCO's proposal and decided to allow ARCO
to prove its effectiveness during the remedial design phase of the source
control operable unit. However, if the design of the ARCO remedy fails to
satisfy EPA criteria, the ROD stated that incineration will be the remedy. The
ARCO proposal includes the following actions:
• Excavation and off-site thermal destruction of sludges
in the waste oil and solvent lagoon areas; and
• Solidification/stabilization of all remaining sludges
in a manner meeting EPA criteria, and containment of
the resulting matrix in a cell or cells to be
constructed on site in compliance with RCRA
requirements.
Although ARCO's proposal would reduce greatly the mobility of wastes, the
toxicity of wastes would not be reduced and the volume of wastes would actually
increase. EPA is also concerned about the lack of demonstrated permanence of
the solidification alternative. Unlike thermal destruction, which would
eliminate organic contaminants permanently, the capability of solidification or
stabilization techniques to contain high organic wastes securely and permanently
has not been demonstrated in the pilot studies conducted on site. However, ARCO
has assured EPA that if the remedy fails, the company will take further
corrective action. ARCO has signed a consent decree to conduct the remedial
design and remedial action. Remedial design is anticipated to begin in the
summer of 1988.
This remedy is expected to be technically feasible and to meet ARARs. The
ARCO proposal initially would cost less than thermal destruction, and the State,
local agencies, and residents support it.

CRYSTAL CITY AIRPORT SITE
CRYSTAL CITY, TEXAS
MRS Score: 3226 NPL Rank: 639
Background
The Crystal City Airport site is located in Crystal City, Zavala County,
Texas, approximately 100 miles southwest of San Antonio. Several private
companies conducted aerial pesticide application businesses at the airport until
1982. In response to concerns that agricultural chemicals left by defunct aerial
operators presented a threat to local residents, the Texas Department of Water
Resources conducted a preliminary investigation of the site. The results of this
investigation, and of follow-up investigations, indicated that surface soil was
highly contaminated with pesticides.
In October 1983, EPA initiated an immediate removal action to remove 40
yards of waste and 50 to 70 drums of the most highly contaminated materials.
In a second removal action, initiated in May 1984, EPA transported 19 drums off
site for disposal, constructed a fence with a locked entrance gate, and posted
warning signs. A draft remedial investigation/feasibility study (RI/FS) for the
site was completed in April 1987, and the ROD was signed September 29, 1987.
Five potentially responsible parties (PRPs), including the City of Crystal
City, have been identified. Four PRPs are no longer in business and the City
appears unable to finance the cleanup.
Description of Site Work
Following the immediate removal actions, EPA and the State of Texas entered
into a cooperative agreement in September 1985 to perform an RI/FS at the site.
A draft RI report submitted in April 1987 identified 2 primary areas in which
surficial soil contamination was 1 to 3 feet deep. A combined cleanup level of
100 mg/kg was proposed for the contaminants of greatest concern: toxaphene, DDT,
and arsenic. The RI determined that remedial action would be required to reduce
the potential for public health exposure through direct contact with and
ingestion of contaminated soils and inhalation of contaminated dust particles.
The RI indicated that treatment for surface-water, ground-water, and ambient-
air contamination would not be needed.
Description of Feasibility Study
In order to meet the objectives of reducing soil contamination levels to
100 mg/kg total pesticide (toxaphene, DDT, arsenic), maintaining background air
quality levels, and minimizing surface-water degradation, a number of potentially
applicable remedial technologies were studied. An initial screening based on
the criteria of long- and short-term environmental and health effects,
implementability, and cost was performed, after which eight alternatives
remained:
(1) No action;
302
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
(2) In-place containment of soils with an 8-acre, 9-inch
asphalt cap;
(3) Consolidation of wastes and capping with a multi-
layered cap;
(4) Containment of soil (without treatment) in an off-site
landfill;
(5) Solidification of contaminated soil and placement in
an off-site landfill;
(6) On-site incineration and soil washing of contaminated
soil;
(7) Placement of soil in an off-site landfill; and
(8) Decontamination of soil (soil flushing) through
utilization of a critical pressure fluid extraction
unit.
The following applicable or relevant and appropriate requirements (ARARs)
for the site were identified: Clean Water Act (CWA) water quality standards,
Clean Air Act (CAA) National Ambient Air Quality Standards (NAAQS), the Texas
Solid Waste Disposal Act, and the Texas Clean Air Act.
Some community members attending the public meetings for the site expressed
support for incineration of the contaminants. Some commenters alleged that the
proposed remedy (Alternative 3) was "substandard" and did not meet CERCLA
statutory preferences for permanent remedies and treatment alternatives that
significantly reduce the mobility, toxicity, or volume of the contaminants. EPA
indicated, however, that such soil treatment alternatives would not
significantly reduce the mobility of the contaminants, because of the
characteristics of the contaminants and the impermeable nature of the soils.
Although toxicity of organic contaminants could be reduced through an integrated
incineration system, the technology necessary to remove the arsenic compound
from the soil does not exist.
Description of Selected Remedy
The alternative recommended for the site includes on-site consolidation and
RCRA-approved capping of soil whose contamination exceeds a combined total of
100 mg/kg toxaphene, DDT, and arsenic (Alternative 3). The proposed remedy will
minimize the forces that drive the transport of waste from the site and will
remove the direct contact threat. Although the remedy selected does not involve
permanent treatment, it is expected to attain ARARs.

HIGHLANDS ACID PIT SITE
GROUND-WATER REMEDIATION OPERABLE UNIT
HIGHLANDS, TEXAS
HRS Score: 37.77 NPL Rank: 450
Background
The Highlands Acid Pit site is located on a sparsely populated area 1.4
miles west of Highlands, Texas. Dense vegetation covers the site, except for
a bare area at the site center that is believed to be the primary dumping area.
The site was used for the disposal of industrial waste sludge, protably sulfuric
acid from a refinery process, during the early 1950s. Organic and inorganic
constituents have been found in the site's shallow aquifer.
In 1984, EPA signed a ROD addressing the source of contamination at the
site. The remedy called for excavation and disposal of contaminated soil and
the installation of a ground-water monitoring system. The ground-water
remediation phase is a separate operable unit, for which an independent ROD was
signed June 26, 1987. The ground-water operable unit is based on the remedial
investigation/feasibility study (RI/FS) conducted in preparation for the 1984
ROD, and on subsequent studies of ground-water contamination.
Only one potentially responsible party (PRP), the landowner, has been
identified. This PRP lacks the resources to underwrite ground-water
remediation, and attempts to locate generators of the waste have failed. EPA
therefore proposes to use Fund resources for the ground-water remediation
operable unit.
Description of Site Work
Prior to the 1984 ROD, EPA conducted an RI/FS to assess wastes in the
hydrogeologic system. This RI included information relevant to the ground-water
operable unit. In November 1985, EPA conducted a further ground-water study to
evaluate the potential for shallow contaminants to migrate after the source of
contamination was removed.
Sampling results revealed high concentrations of volatile organic compounds
(VOCs) and metals in the shallow aquifer. Contaminants of major concern
included benzene, pyridine, cadmium, chromium, and lead. No contaminants of
concern were detected in the middle aquifer. Studies of the ground-water flow
indicated that the contaminants will attenuate to nondetectable levels in about
350 years. Inorganics at the site will settle between the top and middle
aquifers; organics, if they reach the middle aquifer, could be detected by
ground-water monitoring before levels of concern are reached.
Description of Feasibility Study
A feasibility study (FS) for the ground-water operable unit was completed
in 1986 to eliminate or reduce the risk of future exposure to the shallow
aquifer contamination. EPA developed five remedial alternatives to be evaluated
304
-------
Progress Toward Implementing Supcrfund: Fiscal Year 1987
during the FS, and subsequently performed ground-water studies to provide the
necessary data for the evaluation. The following alternatives were considered:
(1) Isolation of the upper aquifer;
(2) Recovery and off-site disposal;
(3) Recovery, biological treatment, and discharge/disposal;
(4) Recovery, carbon absorption, and discharge/disposal;
and
(5) No action, with ground- and surface-water monitoring.
As required by CERCLA, EPA considered applicable or relevant and
appropriate requirements (ARARs) in evaluating the alternatives. Water Quality
Criteria (WQC) were judged to be ARARs for contaminants in the upper aquifer
because of the hydrogeologic connection to surface waters. Maximum Contaminant
Level concentrations (MCLs) were determined to be ARARs for the deeper ground
waters.
Description of Selected Remedy
EPA recommended selection of the "no action" alternative (Alternative 5),
which included monitoring of the surface environment and ground water. EPA
determined that this alternative was consistent with legal requirements and was
protective of public health and the environment. This judgment rested on the
finding that although organics and inorganics are present in the shallow
aquifer, they have not affected deeper ground water. Once the source removal
is complete, the migration of contaminants to the shallow aquifer will be
reduced. The natural flow of water will attenuate present contaminants, leaving
the middle aquifer unaffected.
Although CERCLA promotes the selection of permanent remedies that reduce
the toxicity, mobility, or volume of contaminants, the long- and short-term
effects of the preferred remedy compare favorably with the other alternatives.
Because the ground-water recovery alternative would have exposed area residents
to the contaminants over a 7- to 9-year period, it was eliminated as an option.
The 1986 Land Disposal Restrictions prevented the selection of the alternative
to recover and dispose of ground water.
EPA and the Texas Water Commission participated in a public meeting held
on May 12, 1987, to discuss the details of the remedy. Those attending the
meeting generally expressed satisfaction with the remedy.

PETRO-CHEMICAL SYSTEMS INC., SITE
FRONTIER PARK ROAD OPERABLE UNIT
LIBERTY, TEXAS
HRS Score: 29.94 NPL Rank: 728
Background
The Petro-Chemical site is a 296-acre tract of land located in a sparsely
populated area south of Liberty in southeastern Texas, approximately 40 miles
northeast of Houston. In the northwest corner of the site, unspecified waste
oils were stored in several pits. In June 1970, all disposal operations were
discontinued. Waste oils also were spread on Frontier Park Road as a method of
dust control. The road lies within the site boundary and provides the primary
access to persons living at the site. The site has been inhabited by as many
as 11 families since 1974, although only two families remain as of August 1986.
Preliminary sampling performed by the Texas Water Commission (TWC) in 1982
and 1984 revealed elevated concentrations of polyaromatic hydrocarbons (PAHs)
in the disposal pits. The State lead remedial investigation/feasibility study
(RI/FS) for the site was completed in November 1986, and the ROD was signed
March 27, 1987.
Four potentially responsible parties (PRPs) have been identified for the
site, including three landowners and one transporter of the waste. None of the
PRPs has complied with an administrative order to install a fence around the
main disposal area, nor have they indicated any responsibility or willingness
to fund any portion of the cleanup.
Description of Site Work
The State initiated an RI/FS for the site in March 1985, and RI activities
were conducted in February and June of 1986. The sampling efforts identified
several areas of soil that were moderately to highly contaminated with PAHs,
particularly benzene and naphthalene. Because Frontier Park Road has
significant quantities of contaminated soils and is the primary access road for
residents, the risk of exposure through inhalation of dust particles and
volatilization of contaminants during wet periods is very high. For this
reason, the TWC and EPA decided'to address the RI/FS activities relating to the
road as one operable unit, and to consider the storage pits and other site
contamination at a later date.
Description of Feasibility Study
The RI/FS developed the following objectives for the Frontier Park Road
operable unit: (1) prevention of direct contact with highly contaminated soils;
(2) minimization of direct contact with moderately contaminated soils; and (3)
improvement of access to the site for heavy equipment to facilitate RI sampling
and monitoring and future remedial actions.
306

Progress Toward Implementing Superfund: Fiscal Year 1987
During the detailed analysis of alternatives the following eight remedies
were considered:
(1) On-site storage with relocation;
(2) On-site storage with detours;
(3) Off-site disposal with relocation;
(4) Off-site disposal with detours;
(5) Fence around perimeter of contaminated area,
pavement cover on contaminated soils, and
temporary alternative access;
(6) Removal of contaminated soils to attain background
levels of contamination, and off-site disposal;
(7) Construction of surface barrier; and
(8) No action.
The alternatives were evaluated and rated with respect to performance,
reliability, engineering implementability/constructability, environmental
impacts, costs, the requirements of CERCLA for using permanent solutions and
treatment technologies, and ability to meet applicable or relevant and
appropriate requirements (ARARs). The RI/FS identified the following ARARs:
Resource Conservation and Recovery Act (RCRA) Part 264 General Facilities,
Ground-water Protection, and Closure regulations; and the Clean Air Act (CAA)
National Ambient Air Quality Standards (NAAQS). The Federal Water Quality
Criteria (WQC) are also listed in the ROD as ARARs, but the ROD does not
indicate whether any of the proposed remedies will attain these criteria.
Public meetings concerning the site were held in November 1985 and November
1986. Because of the public's interest in the site, a State disposal permit was
revoked in 1974; citizens currently are concerned that the site might be used
for future disposal of waste from other Superfund sites. Residents were also
concerned about drainage and health problems associated with the contamination.
Description of Selected Remedy
The recommended alternative was on-site storage with relocation
(Alternative 1) , and involved excavation and removal of highly contaminated
soil, backfilling with clean soil, temporary on-site storage of soil,
construction of a road over excavated areas and existing roadway, and temporary
relocation of residents during excavation.
EPA indicated that the chosen remedy is expected to comply with ARARs, and
is the lowest-cost remedy that mitigates short- and long-term threats to human
health and the environment. Operation and maintenance of the on-site RCRA
storage area will consist of maintaining and operating a leachate collection
system. EPA will conduct operation and maintenance of the leachate collection

system for the first year after which time the State of Texas will assume full
responsibility. EPA will be responsible for the operation and maintenance of
the road and temporary storage facility until a final remedy is selected.

CONSERVATION CHEMICAL COMPANY SITE
KANSAS CITY, MISSOURI
HRS Score: 29.99 NPL Rank: Group 15
Background
The Conservation Chemical Company (CCC) site is located within the city
limits of Kansas City, Missouri. The 6-acre site is situated on the floodplain
of the Missouri River and is underlain by the Missouri River alluvium, a source
of drinking water both for private residents and public water-supply companies.
From 1960 to 1980, the site was used as a chemical treatment and disposal area,
and it received liquids, solids, and sludges. Operating records indicate that
the CCC facility received as much as 330,000 tons of material, primarily
composed of organics, solvents, acids, metal hydroxides, cyanide, pesticides,
waste oils, and halogenated compounds. Most of the materials reportedly were
disposed of on site, with or without treatment, in large basins or lagoons.
In 1975, the Missouri Department of Natural Resources (MDNR) investigated
the site and requested that CCC cease the disposal of wastes and take remedial
action to clean up the site. In 1977, the Missouri Clean Water Commission
ordered the site closed and covered. CCC submitted a plan for closure in 1979
that called for adding adsorbents and cementing materials to the upper five
feet of waste of each basin as a temporary measure to prevent migration. Tests
conducted on samples in 1985, however, indicated that the desired cement-like
properties had not formed.
EPA and MDNR located potentially responsible parties (PRPs) for the wastes
disposed of at the CCC site. The PRPs, including IBM, AT&T Technologies, Inc.,
Armco, Inc., and FMC Corporation, undertook a Remedial Investigation (RI) in the
early 1980s to determine the extent of ground-water contamination. EPA entered
into a joint agency agreement with the U.S. Army Corps of Engineers (COE) to
complete a Focused Feasibility Study (FFS) in 1985. An Addendum to the FFS was
completed in 1987 after EPA determined that the initial alternative recommended
for the site would be difficult to implement. The ROD for the site was signed
September 30, 1987.
Description of Site Work
The RI conducted by the PRPs identified 21 substances in ground water beneath
the site in concentrations that substantially exceeded the applicable criteria
or standards for water quality. The primary constituents identified were six
metals, cyanide, four phenolic compounds, and 10 volatile organic compounds
(VOCs) . Dioxin also was detected in concentrations as high as 29 parts per
billion (ppb). (A level of 1 ppb is recommended as a guideline for permissible
concentrations where direct contact is likely.) The RI also indicated that the
greatest exposure pathway was associated with wastes buried at the site that
were in contact with the aquifer; the second pathway of exposure was
contaminated surface soils.
309
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
The original joint EPA/COE FFS assembled available technologies into nine
combinations of alternative remedial actions, and also proposed a "no action"
alternative. Of these, the government chose circumference containment of wastes
and on-site ground-water withdrawal and treatment as the preferred option.
Additional geotechnical analysis, however, revealed that implementation of this
remedy would be more difficult than originally believed. Because of this, and
because the SARA amendments to CERCLA in 1986 added new criteria for the
evaluation of remedies, an Addendum to the FFS was prepared to consider
additional remedial action alternatives.
The Addendum to the FFS conducted by the COE developed alternatives for
remedial actions that met the statutory preferences of CERCLA, including use of
permanent solutions and alternative treatment technologies to the maximum extent
practicable, compliance with all Federal and State applicable or relevant and
appropriate requirements (ARARs), and protection of human health and the
environment. In addition to the preferred alternative under the initial FFS,
the Addendum proposed two additional remedies for full evaluation against the
CERCLA criteria:
(1) On-site containment of contaminants by ground-water
pumping and on-site treatment; and
(2) Excavation of hazardous materials, followed by soil
treatment.
ARARs identified during the Addendum to the FFS for ground-water
remediation at this site included Safe Drinking Water Act (SDWA) Maximum
Contaminant Levels (MCLs) and Maximum Contaminant Level Goals (MCLGs); Clean
Water Act (CWA) Water Quality Criteria, health advisories, Potency Factors, and
verified Reference Doses; and Resource Conservation and Recovery Act (RCRA)
ground-water protection standards. ARARs for discharges to the Missouri River
included the CWA and the Missouri Clean Water Law. ARARs for soil remediation
included RCRA closure requirements.
Public notices were issued requesting comments on the draft RI, FFS, and
the addendum to the FS, a court hearing with defendants, the completion of the
Addendum to the FFS, and the selection of the final remedy. However, few
comments were received from the public.
Description of Selected Remedy
The alternative selected was containment of contaminants through an on-site
ground-water pump and treatment system. Specifically, this remedy incorporates
surface cleanup, a protective surface cap, a withdrawal well system, a ground-
water treatment system, and an off-site ground-water quality monitoring system.
This remedy was determined to be protective of human health and the environment,
cost-effective, and in compliance with the statutory mandate to achieve all
ARARs. The State of Missouri concurred with the final remedy selected.

MINKER/STOUT/ROMAINE CREEK SITE
ROMAINE CREEK OPERABLE UNIT
JEFFERSON COUNTY, MISSOURI
HRS Score: 36.78 NPL Rank: 474
Background
The Minker/Stout/Romaine Creek hazardous waste site is located in Jefferson
County, Missouri, approximately 20 miles southwest of St. Louis. Romaine Creek,
located in a rural residential area, starts at the Minker area and flows 4.6
miles to its confluence with Saline Creek, which empties into the Meramec River
0.2 miles down-stream. The water from Romaine Creek is used neither for
domestic water supply nor for municipal or industrial purposes.
Romaine Creek is contaminated with dioxin from the erosion of 120 cubic
yards of soil deposited at the Minker property, which is being addressed as a
separate operable unit. The contaminants in Romaine Creek originated from a
chemical plant in southwest Missouri, that produced hexachlorophene and dioxin
in the late 1960s and early 1970s. In March 1973, dioxin-contaminated soil was
deposited at several locations that now constitute the individual' portions of
the Minker/Stout/Romaine Creek site. Since 1973, a significant quantity of the
Minker fill has eroded into Romaine Creek. The Stout area, which is being
addressed as another operable unit, is nearby, but not adjacent to, the Minker
area. Because of the similarities of the three areas, the remedial action
selection process for all three operable units was conducted simultaneously.
Cleanup actions taken to date include the excavation of soils exceeding 1
ppb dioxin at the Minker area in 1986, and the posting of warning signs along
the contaminated portion of Romaine Creek. The Romaine Creek Operable Unit
Feasibility Study (FS) was completed in July 1987, and the ROD for the interim
remedy was signed September 28, 1987.
Description of Site Work
EPA initially sampled and analyzed Romaine Creek sediments for dioxin in
1982. On the basis of 150 samples, EPA determined the dioxin contamination at
a level of 1 ppb extended approximately 6,000 feet downstream from the Minker
area. In 1985, biota and additional sediment samples were collected, revealing
dioxin concentrations as high as 36.3 ppb 0.5 mile downstream from the site, and
concentrations of 0.3 ppb 4.5 miles downstream from the site. The biota
sampling detected dioxin in all aquatic species sampled (fish, crayfish, and
amphipods) at levels greater than 50 parts per trillion (ppt).
Description of Feasibility Study
The objectives of the EPA lead FS included: (1) preventing or reducing
long-term human contact with soils containing dioxin at concentrations exceeding
1 ppb, the level that is determined to be protective of human health and the
311
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
environment; and (2) minimizing the potential for off-site migration of dioxin.
The following operable unit remedial action alternatives were developed:
(1) No Action;
(2) Limited action -- implementation of site-use
restrictions, and annual monitoring of Romaine Creek
and nearby wells;
(3) Stabilization of sediments to achieve maximum of 1 ppb
dioxin contamination using vegetation and manufactured
erosion-control mats;
(4) Excavation to 1 ppb and temporary on-site storage; and
(5) Complete excavation and storage of all sediments within
Romaine Creek.
Because the operable unit alternatives evaluated for this FS represent only
part of the complete remedy for Romaine Creek, it is not necessary for them to
comply with applicable or relevant and appropriate requirements (ARARs) for the
entire site. All operable unit alternatives evaluated are consistent with final
remedial actions; these final remedial actions potentially could meet all ARARs.
ARARs identified for this operable unit include land disposal restrictions for
dioxin-contaminated wastes and Resource Conservation and Recovery Act (RCRA)
storage requirements.
As with the Stout and Minker operable units, affected residents are in
general agreement that the contaminated soil should be excavated and transported
off site for treatment and disposal. Given the absence of an off-site
management option, the public is expected to accept interim storage as the only
alternative available at this time. Some local objection is expected near the
location where the required on-site storage structures will be built. The state
has indicated its support for excavation and interim storage of sediments with
contamination exceeding 1 ppb dioxin at Romaine Creek.
Description of Selected Remedy
The remedy selected for this operable unit involves excavation of creek
sediments with greater than 1 ppb dioxin contamination by using vacuum equipment
or other appropriate means. Innovative excavation techniques, particle
separation technologies, and other procedures capable of reducing the amount of
material removed from the creek (and reducing environmental disturbance) will
be examined during the design phase. Excavated sediments will be stored in four
fully-enclosed temporary storage structures constructed on-site until a final
treatment, storage, or disposal option can be selected. If a final management
alternative becomes available, it is possible that contaminated soil can be
taken directly to the location where final management is available. The Agency
has proposed off-site thermal treatment of contaminated soils as a final remedy.
Such a remedy would satisfy CERCLA statutory preferences for permanent,
treatment-based remedies.
312
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
This remedy mitigates the potential for human and environmental contact
with contaminated sediments and reduces the possibility of continued erosion of
these sediments. In addition, it is more protective, reliable, and
implementable than other alternatives, and it results in less environmental
disruption than complete excavation of all sediments.

MINKER/STOUT/ROMAINE CREEK SITE
STOUT OPERABLE UNIT
JEFFERSON COUNTY, MISSOURI
HRS Score: 36.78 NPL Rank: 474
Background
The Minker/Stout/Romaine Creek hazardous waste site is located in Jefferson
County, Missouri, approximately 20 miles southwest of St. Louis. The Stout
site, comprises five properties (the Vogt property, the Sutton property, and the
former Hutchinson, Cisco, and Baczynski properties) and is located near the top
of a steeply sloping hillside in an unincorporated, low-density area near
Imperial, Missouri.
Dioxin contamination exists in surficial soils on most of the Sutton
property and on adjacent portions of the Vogt and Hutchinson properties. The
contaminants originated from a chemical plant in southwest Missouri, which
produced hexachlorophene and dioxin in the late 1960s and early 1970s. In March
1973, dioxin-contaminated soil was deposited at several locations that now
constitute the individual portions of the Minker/Stout/Romaine Creek site.
Approximately 700 cubic yards of this soil were deposited at the Stout area.
The Minker/Stout/Romaine Creek site also includes the Minker area, a tract of
land nearby, but not adjacent to, the Stout area, and Romaine Creek, a
contaminated creek running from the Minker area. Each of these areas is being
addressed as a separate operable unit. Because of the similarities of the three
areas, however, the remedial action selection process for all three operable
units was conducted simultaneously.
Remedial actions performed by EPA to date include the permanent relocation
of three residences following discovery of dioxin contamination in 1982. The
Stout Operable Unit Feasibility Study (FS) was completed in July 1987, and the
ROD for the interim remedy selected was signed September 28, 1987.
Description of Site Work
Several investigations of soil contamination at the Stout area were
conducted during 1982, 1983, and 1986. These investigations indicated that
dioxin levels in the soil (up to 241 ppb) require remediation to assure
protection of human health and the environment. According to 1983 sampling,
contamination was limited to the Stout area and approximately 800 feet along an
unnamed intermittent stream. A maximum dioxin concentration of 11 ppb has been
detected in this portion of the stream. The 1986 sampling indicated that the
areal extent of contamination exceeding 1 ppb is approximately 1.1 acres.
Description of Feasibility Study
The objectives of the FS conducted by EPA included: (1) prevention or
reduction of long-term human contact with soils containing dioxin at
concentrations exceeding 1 ppb, the level at or below that which is determined
to be protective of public health and the environment; and (2) minimization of
314
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
the potential for off-site migration of dioxins. The following five remedial
action alternatives were developed for the site:
(1) No action;
(2) Limited action -- implementation of site-use
restrictions, seeding of sparsely vegetated areas, and
surface-water controls and annual monitoring;
(3) Stabilization of soils to achieve maximum of 1 ppb
dioxin contamination;
(4) Excavation to achieve maximum of 1 ppb dioxin
concentration and temporary on-site storage; and
(5) Complete excavation and storage.
Because the operable unit alternatives evaluated for this FS represent only
part of the complete remedy for the Stout area, it is not necessary for them to
comply with applicable or relevant and appropriate requirements (ARARs) for the
entire site. All operable unit alternatives evaluated are consistent with final
remedial actions; these final remedial actions potentially could meet all ARARs.
ARARs identified for this operable unit include land disposal restrictions for
dioxin-contaminated wastes, and Resource Conservation and Recovery Act (RCRA)
storage regulations.
Affected residents are in general agreement that the contaminated soil
should be excavated and transported off site for treatment and disposal. Given
the absence of an off-site management option, the public is expected to accept
interim storage as the only alternative available at this time. Some local
objection is expected near the location where the required on-site storage
structures will be built. The State of Missouri has indicated its support for
excavation and interim storage of soils with contamination exceeding 1 ppb
dioxin at the Stout area.
Description of Selected Remedy
The remedy selected for this operable unit involves excavation of soils
with contamination exceeding 1 ppb dioxin to a maximum depth of 4 feet of
bedrock. Excavated areas will be backfilled to original grade with clean
material and revegetated. Excavated soil will be stored in four fully-enclosed
temporary storage structures constructed on site, until a final treatment,
storage, or disposal option can be selected. If a final management alternative
becomes available, it is possible that contaminated soil can be taken directly
to the location where final management is available. Although a final remedy
has not been selected for the entire site, the Agency has proposed off-site
thermal treatment of contaminated soils. Such a remedy would satisfy CERCLA
statutory preferences for permanent, treatment-based remedies.
The selected remedy is cost-effective and protects human health and the
environment by reducing the potential for continued erosion of contaminated
soils. In comparison with the selected remedy, complete excavation of the
315
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
entire fill area cannot be justified at the additional cost because both
alternatives reduced surface dioxin concentrations to below 1 ppb, the level
that assures protection of public health and the environment. Stabilization of
contaminated soils was not proposed due to the uncertainty of successful
implementation and high operation and maintenance requirements.

CLEAR CREEK/CENTRAL CITY SITE
OPERABLE UNIT I
CLEAR CREEK AND GILPIN COUNTIES, COLORADO
HRS Score: 5139 NPL Rank: 157
Background
The Clear Creek/Central City site is located in the northeastern portion
of the Colorado Mineral Belt, approximately 30 miles west of Denver, Colorado,
near the cities of Idaho Springs, Black Hawk, and Central City. Acid mine
drainage and milling and mining waste discharges from five abandoned mines and
tunnels at the site caused surface-water contamination consisting of dissolved
and suspended metals, including aluminum, cadmium, and lead.
The Clear Creek/Central City mining site is one of the more extensively
mined areas in Colorado. Mining and construction of the tunnels began in the
early 1900s, and the entire area includes over 800 abandoned mine workings and
tunnels. The Clear Creek/Central City site was added to the NPL in 1983, and
EPA began a Remedial Investigation (RI) for the entire site in June 1985.
During the RI, EPA determined that an interim remedy operable unit was needed
to address treatment of mine drainage. A feasibility study (FS) for the
Operable Unit I remedy was completed in June 1987 and the ROD was signed
September 30, 1987. Separate FSs will be prepared for Operable Units II through
III to address additional site degradation. The determination of the final
remedy is contingent upon the completion of the operable units.
A potentially responsible party (PRP) search did not identify any PRPs for
the mine tunnel discharges, which are the focus of Operable Unit I. The PRP
search, however, revealed information concerning ownership of mine tailings
which have been identified as a source of metals contamination of surface water
resulting from seepage of ground water through the tailing piles. Operable Unit
II will address contamination from this source.
Description of Site Work
The RI for the entire site was completed in June 1987 and indicated that
concentrations of metals in the mine tunnel discharges exceed Federal drinking
water standards. Ambient water quality criteria, which are designed to protect
aquatic life, have also been exceeded, in certain instances by more than two
levels of magnitude. A public health evaluation (PHE) identified eleven
contaminants of concern: aluminum, arsenic, cadmium, chromium, copper,
fluoride, lead, manganese, nickel, silver, and zinc. Risks to human and aquatic
life are associated with exposure to surface water from ingestion and direct
contact. The PHE showed that there is no immediate danger from mine tunnel
discharge at present flow rates, although mine tunnel discharges have had severe
adverse impacts on water quality and the aquatic habitat.
317
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
Alternatives identified in the FS were initially screened on the basis of
cost, effectiveness, and implementability. These remaining alternatives were
subject to a detailed analysis:
(1) No action;
(2) Passive treatment -- creation of an artificial wetland
to emulate or enhance natural metal ion removal and
acidity reduction processes;
(3) Active treatment -- alkaline precipitation (using lime,
sodium hydroxide, or sulfide) or electrochemical
precipitation; and
(4) Combination of active and passive treatment.
Contaminant-specific ARARs for the site are Maximum Contaminant Levels
(MCLs) under the Safe Drinking Water Act (SDWA) and Ambient Water Quality
Criteria (AWQC) established under the Clean Water Act (CWA). State ARARs
include State water quality and anti-degradation standards. Location- and
action-specific ARARs include historic preservation regulations, executive
orders on floodplains and wetlands, the National Pollution Discharge Elimination
System (NPDES), and Subtitle D of the Resource Conservation and Recovery Act
(RCRA).
Community relations at the site included public meetings after the release
of the Operable Unit I FS, the establishment of information repositories, and
establishment of the administrative record.
Description of Selected Remedy
The selected interim remedy for Operable Unit I consists of construction
of passive treatment systems to treat mine tunnel discharges prior to discharge
to surface waters (Alternative 2) . If upstream water quality concentrations
cannot be achieved by passive treatment, then one of the following two treatment
systems will be constructed:
• Combination system of passive and active treatment; or
• Two active treatment systems.
The selected interim remedy is cost-effective and is expected to be
protective of human health and the environment. Target treatment levels for the
interim remedy are upstream water quality concentrations. The interim remedy
requires the exercise of the CERCLA section 121 "interim remedy" waiver from
contaminant-specific ARARs. EPA intends that the final remedy will, at least,
attain water quality criteria established under the CWA. The interim remedy is
expected to be consistent with the final site remedy. In addition, passive
treatment is an innovative technology, and the installation of either of the
318
-------

treatment systems meets the CERCLA statutory preference for permanent solutions
that reduce the mobility, toxicity, or volume of metals in the discharge.

DENVER RADIUM SITE
OPERABLE UNIT I -- 12th AND QUIVAS PROPERTIES
DENVER, COLORADO
HRS Score: 44.11 NPL Rank: 284
Background
Operable Unit I of the Denver Radium site consists of 4 of the more than
31 radioactive properties that EPA has identified in the Denver area. The
radioactive contamination at the Denver Radium site properties originated from
a number of radium, vanadium, and uranium processing operations conducted during
the 1910s and 1920s. Because of the enormity of the Denver Radium site, EPA
divided the site into 11 operable units. Operable Unit I is located at the 12th
and Quivas Streets properties in the City of Denver, where releases of radium
and its associated decay products are the hazardous substances of primary
concern. The properties cover approximately 8 acres in an area zoned for
industrial use and currently are in use for business operations by various
companies. Until 1924, the Pittsburgh Radium Company, a division of the
National Vanadium Products Company, refined radium-bearing ore at the site
location, and the current contamination is believed to be the result of this
Company's operations.
After EPA identified all 31 contaminated properties, the Radiation Control
Division of the Colorado Department of Health (CDH) notified property owners of
the presence of radium and requested that no excavation be undertaken without
consultation with CDH. In August 1981, CDH, in a cooperative agreement with
EPA, initiated investigation of many of the 31 properties. EPA installed a
vented-plenum wall in the basement of the B&C Metal Products building, which is
included in Operable Unit I, to reduce radon decay product concentrations. EPA
did not take further emergency response actions at the site because the patterns
of occupancy and the concentrations of contaminants during periods of occupancy
reduced the significance of long-term exposure.
The entire Denver Radium site was included on the final NPL published in
September 1983. EPA assumed Fund lead activities in June 1983 because the
Colorado State Legislature failed to appropriate the cost-share required. EPA
initiated the Remedial Investigation (RI) in December 1983, and the RI for all
operable units was completed in April 1986. The draft Operable Unit I
feasibility study (FS) was released in August 1987, and the ROD was signed
September 29, 1987.
A potentially responsible party (PRP) search has not traced the Pittsburgh
Radium Company to any firm that is currently operating. EPA is proceeding with
a Fund-financed remedial design and remedial action. If PRPs are identified,
EPA will attempt to recover response costs from the PRPs.
Description of Site Work
Radium and its associated decay products are the primary contaminants of
concern. Long-term exposure to these substances has been shown conclusively to
increase the risk of contracting lung cancer. EPA used a gamma radiation survey
to outline the extent of possible radium contamination and verified the presence
320
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
of radium in the soil and underneath the buildings on site by radio-chemical
analysis of subsurface soil samples. Radium concentrations, gamma radiation
levels, and radon decay product concentrations found in three buildings on the
site were of concern because they exceeded the EPA Standards for Remedial
Actions at Inactive Uranium Processing Sites.
Description of Feasibility Study
EPA evaluated remedial alternatives against the CERCLA requirements that
a remedy be protective of human health and the environment; cost effective;
attain Federal and State applicable or relevant and appropriate requirements
(ARARs); and use permanent solutions and alternative treatment technologies to
the maximum extent practicable, with preference for remedies that permanently
and significantly reduce the toxicity, mobility, or volume of hazardous
substances. The alternatives developed in the FS were:
(1) No action;
(2) Deferred removal and off-site permanent disposal;
(3) On-site reprocessing/treatment and off-site permanent
disposal;
(4) In situ vitrification;
(5) On-site permanent disposal;
(6) Off-site permanent disposal;
(7) On-site temporary land storage and off-site permanent
disposal;
(8) On-site temporary building storage and off-site
permanent disposal;
(9) On-site temporary containment (capping) and off-site
permanent disposal; and
(10) Temporary storage at the Card Corporation property and
off-site permanent disposal.
Federal ARARs identified for the site included: the EPA Standards for
Remedial Action at Inactive Uranium Processing Sites, the Nuclear Regulatory
Commission Standards for Protection Against Radiation, the National Council on
Radiation Protection and Measurements, and the International Commission on
Radiological Protection recommendations for gamma radiation doses.
In July 1987 , EPA met with the owners and tenants of the properties on the
site. Topics discussed included concerns about adverse publicity to the firms
on site and details of the remedial action phase. In August 1987, EPA held a
public meeting where concerns raised included the effect of the remedial action
on business operations on site and the liability of owners and tenants. The
321
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
public generally supported the complete excavation and permanent off-site
disposal of all materials.
Description of Selected Remedy
The initial preferred alternative for the site was permanent off-site
disposal. Until the State of Colorado agrees to a permanent disposal site for
material removed from the properties, however, this alternative cannot be
implemented. Consequently, the remedial design for Operable Unit 3 includes on-
site temporary containment and off-site permanent disposal. The temporary
response action consists of capping the contamination at the properties and
excavating materials from under three buildings and temporarily storing them on
site. The final and permanent source control response action will occur when
a disposal facility becomes available. Included in the remedy is review of the
site pursuant to CERCLA section 121(c) if any hazardous materials remain on site
for more than 5 years.
The selected alternative is cost-effective, is expected to meet ARARs, and
provides adequate protection of public health and the environment. The selected
remedy, however, does not satisfy the preference for treatment as a principal
element. Because of the radioactive nature of radium, no technology was
identified that would result in a permanent or significant decrease in the
toxicity, mobility, or volume of the radium on site.

DENVER RADIUM SITE
OPERABLE UNIT II -- 11TH AND UMATILLA PROPERTIES
DENVER, COLORADO
HRS Score: 44.11 NPL Rank: 284
Background
Operable Unit II of the Denver Radium site consists of 11 of the more than
31 radioactive properties that EPA has identified in the Denver metropolitan
area. The radioactive contamination at the Denver Radium site properties
originated from a number of radium, vanadium, and uranium processing operations
conducted during the 1910s and 1920s. Because of the enormity of the Denver
Radium Site, EPA divided the site into 11 operable units. The 11 properties in
Operable Unit II cover approximately 24 acres and are currently used for various
business operations. The contaminants of concern, radium and its decay
products, can be traced to the Radium Company of Colorado, which processed
radium-bearing ore on the Operable Unit II site until 1921.
After EPA identified the 31 radioactive properties, the Radiation Control
Division of the Colorado Department of Health (CDH) contacted the owners of the
properties and requested that no excavation be done on the site without
notification of the Division. In 1981, CDH, in a cooperative agreement with
EPA, assumed lead activities at the Denver Radium site. Among other activities
on the Operable Unit II, CDH and EPA oversaw the installation of subfloor
venting measures and a vapor barrier at the DuWald Steel property to prevent
radon from entering the building. The entire Denver Radium site was included
on the NPL in September 1983. EPA assumed Fund lead activities in 1983 when the
Colorado State Legislature failed to appropriate the State cost share. The
Remedial Investigation (RI) for all the operable units was completed in April
1986. The feasibility study (FS) for Operable Unit II was completed in August
1987, and the ROD was signed September 29, 1987.
A potentially responsible party (PRP) search has failed to trace the Radium
Company of Colorado to a present-day company. If PRPs are identified, EPA will
contact them and initiate negotiations for the implementation of the remedy or
take action to recover EPA's response costs.
Description of Site Work
Sampling conducted during the EPA lead RI indicated that radium
concentration in the soils and the radon decay product concentrations and gamma
radiation levels in certain buildings exceeded the EPA Standards for Remedial
Actions at Inactive Uranium Processing Sites. Long-term exposure to radium and
its decay products has been shown conclusively to increase the risk of
contracting lung cancer. Although radon levels in two buildings on the Operable
Unit II site exceed the EPA standards, EPA took no emergency action because one
building is presently unoccupied, and the patterns of occupancy in the other
building reduce the chances of significant long-term exposure. The RI indicated
that contaminants at the site pose a health risk through three potential
exposure pathways: inhalation, direct gamma radiation exposure, and ingestion
of radium-contaminated materials. The health risk at the site results from
possible long-term exposure, and this exposure would increase if any of the
323
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
contaminated material was to become more accessible, if the property was
redeveloped, or if the buildings on site became more airtight or more heavily
used.
Description of Feasibility Study
The FS for the 11 properties in Operable Unit II evaluated alternatives in
accordance with the CERCLA requirements that a remedy be protective of human
health and the environment, cost-effective, attain Federal and State applicable
or relevant and appropriate requirements (ARARs), and use permanent solutions
and alternative treatment technologies to the maximum extent practicable. After
an initial screening, the following remedial alternatives were retained for
detailed analysis:
(1) No action;
(2) Deferred removal and off-site permanent disposal;
(3) On-site temporary land storage and off-site permanent
disposal;
(4) On-site temporary building storage and off-site
permanent disposal; and
(5) Temporary building storage at the Card Corporation
property and off-site permanent disposal.
Federal ARARs identified for the site include the EPA Standards for
Remedial Actions at Inactive Uranium Processing Sites, and the Nuclear
Regulatory Commission Standards for Protection Against Radiation. The FS also
identified the Executive Order on Flood Plain Management as a potential
location-specific ARAR. Other Federal ARARs considered included the National
Council on Radiation Protection and Measurements and the International
Commission on Radiological Protection (ICRP) recommendations for maximum gamma
radiation dose to the entire body. Additionally, to comply with CERCLA section
104(c) and EPA's off-site disposal policy, the State of Colorado must make
available a disposal facility.
A public meeting was held in August 1987. Major concerns of those who
attended the meeting were the effect of the remedial action on business
operations at the site, the liability of the owners at the site, and the cost
of the remedial action. In general, the community had reservations about
temporary actions that leave contaminants on site and, consequently, the public
supported the excavation and permanent off-site disposal of the contaminated
material.
324
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Selected Remedy
The selected remedy for Operable Unit II of the Denver Radium site is on-
site temporary land storage and off-site permanent disposal. When the State of
Colorado agrees to a disposal facility, EPA will implement its preferred
alternative, off-site permanent disposal.
The alternative is protective of the public health, is expected to attain
ARARs, and is cost effective. Because of the radioactive nature of radium, no
technology was identified that would result in a permanent and significant
decrease in the toxicity, mobility, or volume of the hazardous substance.

DENVER RADIUM SITE
OPERABLE UNIT III -- 1000 WEST LOUISIANA PROPERTIES
DENVER, COLORADO
HRS Score: 44.11 NPL Rank: 284
Background
Operable Unit III of the Denver Radium site consists of five of the more
than 31 radioactive properties that EPA has identified in the Denver area. The
radioactive contamination at the Denver Radium site properties originated from
a number of radium, vanadium, and uranium processing operations conducted during
the 1910s and the 1920s. Because of the enormity of the Denver Radium site,
EPA divided the site into 11 operable units. The Operable Unit III properties,
known collectively as the 1000 West Louisiana properties, cover 11 acres in an
area zoned for industrial use and currently are being used for business
operations.
After EPA identified the 31 contaminated properties, the Radiation Control
Division of the Colorado Department of Health (CDH) notified property owners of
the presence of radium and requested that no excavation be undertaken without
consultation with CDH. In August 1981, CDH, in a cooperative agreement with
EPA, initiated investigation of many of the 31 properties. Although radon decay
levels in the basement of the Creative Illumination Building at the West
Louisiana properties site exceeded EPA standards, an emergency response action
was not taken because the patterns of occupancy and the concentrations of radon
decay products present were such that significant long-term exposure risk was
considered unlikely.
The entire Denver Radium site was included on the final NPL published in
September 1983. EPA assumed Fund lead activities in June 1983 because the
Colorado State Legislature failed to appropriate the cost-share required. EPA
initiated the Remedial Investigation (RI) in December 1983, and the RI for all
operable units was completed in April 1986. The draft Operable Unit III
feasibility study (FS) was released for public review in August 1987, and the
ROD was signed September 29, 1987.
Records indicated that the Chemical Products Company (CPC) operated a
processing facility at the Operable Unit III site from 1918 to 1921 and disposed
of ore processing wastes containing radium. Sources indicated that CPC may have
been a division of the Ludlum Steel Company and may also have been associated
with the Ore Products Company. A potentially responsible party (PRP) search has
not traced CPC to a present-day entity and has not revealed that the present
owners of the properties have any connection to the activities that caused the
radioactive contamination. EPA is proceeding with a Fund-financed remedial
design and remedial action and will attempt to recover costs if PRPs are
identified.

Description of Site Work
Radium and its decay products are the primary contaminants of concern.
Long-term exposure to these substances has been shown conclusively to increase
the risk of contracting lung cancer. EPA used a gamma radiation survey to
outline the extent of possible radium contamination. The presence of radium in
the soil and beneath the buildings was verified by radio-chemical analysis of
subsurface soil samples. A small number of polynuclear aromatic hydrocarbons
(PAHs) and volatile organic compounds were also found in on-site soils. The
radium concentration in the soils on the properties and the radon decay product
concentrations and gamma radiation levels found in one of the buildings exceeded
EPA standards. In addition, alpha radioactivity levels in the building exceeded
State of Colorado guidelines.
The elevated concentrations of radium at the properties present a health
risk through three potential exposure pathways: 1) inhalation of radon gas, the
immediate decay product of radium; 2) direct gamma radiation exposure; and 3)
ingestion or inhalation of radium contaminated materials.
Description of Feasibility Study
The Operable Unit III FS identified the following remedial alternatives as
those warranting in-depth evaluation:
(1) No action;
(2) Deferred removal and off-site permanent disposal;
(3) On-site temporary land storage and off-site
permanent disposal;
(4) On-site temporary building storage and off-site
permanent disposal;
(5) On-site temporary containment (capping) and off-
site permanent disposal; and
(6) Temporary building storage at the Card Corporation
property and off-site permanent disposal.
Federal ARARs identified for the site included: the EPA Standards for
Remedial Action at Inactive Uranium Processing Sites, the Nuclear Regulatory
Commission Standards for Protection Against Radiation, the National Council on
Radiation Protection and Measurements, and the International Commission on
Radiological Protection recommendations for gamma radiation doses.
In July 1987, EPA met with the owners and tenants of the properties on the
site. Neighboring homeowners expressed concern over whether their homes were
contaminated from the 1000 West Louisiana properties and the cost of the
remedial action. In general, the public supports the complete excavation and
permanent off-site disposal of all contaminated materials.
327
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Selected Remedy
EPA1s preferred remedial action alternative for the 1000 West Louisiana
properties is off-site permanent disposal. This alternative, however., cannot
be implemented until the State of Colorado provides a permanent disposal site.
Consequently, the remedial action for Operable Unit III is temporary building
storage at the Card Corporation property for material from the Creative
Illumination Building and on-site storage for the remainder of the .material from
the property. Off-site permanent disposal (Alternative 6) will be implemented
once a permanent disposal facility becomes available. The remedy will include
review of the site pursuant to CERCLA section 121(c) if any hazardous materials
remain on site for more than 5 years.
The selected alternative is cost-effective, is expected to meet ARARs, and
provides adequate protection of public health and the environment. The selected
remedy, however, does not satisfy the preference for treatment that a principal
element because no technology was found which would result in a permanent and
significant decrease in the toxicity, mobility, or volume of the radioactive
substance, radium, on-site.

DENVER RADIUM SITE
OPERABLE UNIT X -- CARD CORPORATION PROPERTY
DENVER, COLORADO
HRS Score: 44.11 NPL Rank: 284
Background:
The Denver Radium site includes the remains of several radium processing
facilities that operated in the 1910s and 1920s. Included in these radium
processing operations are facilities developed by the U.S. Bureau of Mines and
a private corporation, the National Radium Institute (NRI). In 1979, references
in a 1916 NRI report led EPA to discover 31 sites contaminated with radioactive
materials in the Denver area. One of these sites is the 17-acre Card
Corporation property, which was used as a radium processing facility from 1920
to 1924 by the Pittsburgh Radium Company. The industrial-zoned site was owned
by the Card Corporation when radiological contamination was discovered. Mentor
Corporation acquired the property in 1977 without having knowledge of the
contamination on the site.
The Denver Radium site was placed on the final NPL in September 1983. Due
to its enormity, the Denver Radium site has been divided into 11 operable units,
of which the Card Corporation property is Operable Unit X. The Colorado
Department of Health (CDH) assumed the lead in assessing the various properties
in August 1981. However, the current owner of the Card Corporation property,
the Mentor Corporation, denied the State access to the site. Subsequently, an
EPA lead Remedial Investigation (RI) of the entire Denver Radium site was
initiated in December 1983. Draft feasibility studies (FS) for the Card
Corporation property Operable Unit were released in 1986 and 1987, and the ROD
was signed June 30, 1987.
A search for potentially responsible parties (PRPs) for the entire Denver
Radium site has been initiated, but no PRPs have been identified as responsible
for the contamination on the Card Corporation property. The attempt to trace
the Pittsburgh Radium Company to a present-day company has been unsuccessful.
EPA is negotiating a covenant with Mentor not to sue for potential liability
resulting from a release of hazardous substances at the site. In return, Mentor
would provide EPA access to its property for storage of radium-contaminated
materials from other units at the Denver Radium site.
Description of Site Work
The EPA lead RI, completed in April 1986, indicated that the contaminant
of concern at the Card Corporation property is radium. Results of a gamma-
radiation survey indicated that radium was present in the soil, in buildings,
and underneath the buildings. The radium concentration potentially poses a
health hazard through three principal exposure pathways: (1) inhalation of
radon gas, the immediate decay product of radium, and radon's own short-lived
decay products; (2) direct gamma radiation exposure from the decay of radium;
and (3) ingestion or inhalation of radium-contaminated materials. Because the
radium at this site is in a form that is relatively insoluble, and migration of
contaminants into the ground water or pond water was not found, ingestion of
329
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
radium from contaminated surface water or ground water was not a concern at the
Card Corporation property.
Description of Feasibility Study
A first draft of the FS was released for public review in October 1986.
Because public concern was so great, the comment period on the FS was extended.
The primary concern of the public was that the temporary storage facility would
become permanent if the State failed to assure the availability of a permanent
disposal site. Subsequently, the City Council passed a resolution opposing the
storage of any radioactive waste anywhere in the Denver metropolitan area.
Other major concerns raised at the public meeting in November 1986 included:
the impacts of cleanup and storage on area property values; the justification
for temporary storage; health risks from the cleanup; and the risks from
transporting material to the site.
A second draft FS, reflecting comments received on the first draft, was
released for public comment in April 1987. It also incorporated CERCLA
requirements for considering permanent solutions and use of treatment
technologies to the maximum extent practicable and attainment of ARARs. Of nine
alternatives originally considered, five remained after screening:
(1) No action;
(2) Deferred removal with off-site permanent disposal;
(3) On-site permanent disposal;
(4) On-site temporary land storage with off-site
permanent disposal; and
(5) On-site temporary building storage with off-site
permanent disposal.
Several potential Federal and State applicable or relevant and appropriate
requirements (ARARs) were identified for the site including: the EPA Standards
for Remedial Action at Inactive Uranium Processing Sites; the Nuclear Regulatory
Commission Standards for Protection Against Radiation; the National Historic
Preservation Act; and the Archeological and Historic Preservation Act. Action-
specific ARARs were considered in the course of each remedial alternative.
Description of Selected Remedy
EPA's preferred remedial action alternative was permanent off-site
disposal. However, this alternative was eliminated during initial screening
because it cannot be implemented until the State of Colorado agrees to a
permanent disposal site. Instead, EPA selected a remedy that included temporary
on-site building storage with permanent off-site disposal. If a permanent
disposal facility becomes available before this alternative is implemented, EPA
may implement immediately the permanent off-site disposal alternative.
330
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
The selected alternative involves the excavation and temporary storage of
approximately 4,000 cubic yards of radium-contaminated soil from the Card
Corporation property. When a permanent disposal facility is made available, all
material will be removed from the property and transported to the permanent off-
site disposal location. The temporary storage building and any additions to
the building may be dismantled, decontaminated, and disposed of in a sanitary
landfill. This alternative also includes the option of consolidating and
storing radium-contaminated material from other Denver Radium site properties.
In response to public concerns, however, the duration of temporary storage at
the site may not exceed 5 years, and the maximum amount of material that can be
temporarily stored is 13,000 cubic yards.
The selected remedy does not satisfy the statutory preference for treatment
that reduces toxicity, mobility, or volume of the hazardous substances.
Although EPA evaluated several treatment technologies, none were found to be
suitable to the site conditions or the type of contamination present on the Card
Corporation property.

DENVER RADIUM SITE
OPEN SPACE PROPERTIES -- OPERABLE UNITS VI, IX, AND XI
DENVER, COLORADO
HRS Score: 44.11 NPL Rank: 284
Background
The Open Space properties portion of the Denver Radium site includes three
operable units (VI, IX, and XI) and consists of 10 properties in Denver,
Colorado, that are contaminated with radium and its associated decay products.
The radium at these properties is believed to have originated from a number of
radium, vanadium, and uranium processing operations conducted at the site in the
1910s and 1920s. Much of the contamination is the direct result of radium and
uranium processing on the specific properties or the result of processing
wastes being transported to the property from a processing site.
After noting a reference to the National Radium Institute in a 1916 U.S.
Bureau of Mines report, EPA performed field research in 1979 that indicated the
presence of 31 radioactive sites in the Denver metropolitan area. In August
1981, the Colorado Department of Health, under a cooperative agreement with EPA,
assumed lead activities and initiated engineering assessments of the majority
of the original 31 properties. Shortly thereafter, the entire site was placed
on the Interim Priorities List. EPA resumed Fund lead activities in June 1983
because the Colorado State Legislature failed to appropriate the State cost
share for remedial planning required. Because of the enormity of the Denver
Radium site, EPA divided the site into 11 operable units, based upon individual
property locations and conditions. The Denver Radium site Remedial
Investigation (RI) report, which addresses all 11 operable units, was completed
in April 1986. The draft feasibility study (FS) for the Open Space properties
(Operable Units VI, IX, and XI) was released for public review in August 1987.
A detailed search for potentially responsible parties (PRPs) has identified
possible generators of radium contamination for many of the Open Space
properties. Records indicate that many companies conducted activities related
to the current contamination, but the PRP search has yet to trace any of these
companies to a viable, present-day company. The search has not revealed any
connection between the current owners of the Open Space properties and the
activities that caused the respective properties to be contaminated.
Description of Site Work
During the RI, a gamma radiation survey and subsurface soil samples were
taken to determine the extent of possible radium contamination at the Open Space
properties. Soil samples verified that radium contamination existesd in most of
the properties. In all cases where it was detected, radium concentration in the
soil exceeded target levels established in the EPA Standards for Remedial
Actions at Inactive Uranium Processing Sites. The estimated total volume of
radium-contaminated soil at the Open Space properties is 1,458 cubic yards.
The elevated concentration of radium poses a health hazard from three
principal exposure pathways: (1) inhalation of radon gas, and radon's own
short-lived decay products; (2) direct gamma radiation exposure from the decay
332
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
of radium; and (3) ingestion or inhalation of radium-contaminated materials.
Because the radium is in a form that is relatively insoluble, and because it is
not believed that radiological contaminants have migrated into ground or surface
water, potential ingestion or contact with these media are not believed to be
major health risks.
Description of Feasibility Study
In order to mitigate the health risks posed by radium contamination at the
site, the FS developed several remedial action alternatives. After an initial
screening based on CERCLA criteria, the alternatives retained for detailed
analysis included:
(1) No action (all properties);
(2) Deferred removal and off-site permanent disposal (all
properties);
(3) On-site temporary land storage and off-site permanent
disposal (Allied, Brannan, PSCo, and Thomas Realty
properties) ;
(4) On-site temporary building storage and off-site
permanent disposal (Allied, Brannan, PSCo, and Thomas
Realty properties);
(5) On-site temporary containment with a Resource
Conservation and Recovery Act (RCRA) cap and off-site
permanent disposal (all properties); and
(6) Temporary building storage at the Card Corporation
property (located at Operable Unit X) and off-site
permanent disposal (all properties).
Applicable or relevant and appropriate requirements (ARARs) identified for
the site included: the EPA Standards for Remedial Action at Inactive Uranium
Processing Sites, the Nuclear Regulatory Commission Standards for Protection
Against Radiation, and the Executive Order for Floodplain Management. EPA also
considered the National Council on Radiation Protection and Measurements and the
International Commission on Radiological Protection recommendations on maximum
gamma radiation in its analysis of alternatives.
Description of Selected Remedy
EPA's preferred remedy for the site was off-site permanent disposal for all
properties with radium contamination (Alternative 2). However, this alternative
is not immediately implementable because the State of Colorado has not yet
agreed to a facility for the disposal of the Denver Radium site wastes and does
not expect to have a disposal facility developed in the State before 1992.
Therefore, EPA selected a temporary remedy, consisting of the following actions:
333
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
• On-site temporary capping of the Allied property and
eventual excavation and off-site disposal of
contaminated soil; and
• On-site cleanup of six properties; temporary storage
of contaminated soil at the Card Corporation property;
and eventual permanent off-site disposal of
contaminated soil.
The temporary measures included in the selected remedy will provide short-
term protection of public health and the environment. The remedy is cost-
effective, is expected to attain ARARs, and will comply with EPA's off-site
disposal policy. A treatment-based remedy was not chosen for this site because
EPA could not identify an implementable and effective technology to reduce the
toxicity, volume, or mobility of radioactive wastes.
In general, the public supported the selected remedy. However, the local
community does have reservations about any temporary response action because of
the fear that the State will not make available a permanent disposal site for
this material. In addition, certain elected officials voiced concerns about
selecting the "no action" alternative at some of the properties. The portion
of the community in the vicinity of the Card Corporation property strongly
opposes temporary storage of Open Space material at this property because of the
fear that property values will decline.

ROCKY MOUNTAIN ARSENAL SITE
FIRST OFF-POST OPERABLE UNIT
DENVER, COLORADO
HRS Score: 58.15 NPL Rank: Group 2F
Background
The Rocky Mountain Arsenal (RMA) site is located in Adams County about 10
miles northeast of Denver, Colorado. The site covers 27 square miles. Adjacent
areas known as South Adams County include farm land, with residential
subdivisions, industrial facilities, and gravel operations. The RMA post, which
is owned and operated by the U.S. Army, was established in 1942 for the
production of chemical and incendiary munitions. Subsequently, the property was
used to produce pesticides and herbicides under leases to private companies.
Substances from both operations, as well as by-products and residues, were
disposed of on-site.
Studies conducted in one off-post area in south Adams County by EPA and
local authorities indicated that concentrations of volatile organic compounds
(VOCs), such as 1,1-dichloroethane and trichloroethylene, were present in the
ground-water system. Other possible contaminants include benzene, vinyl
chloride, and pesticides. The local water supply system serves about 30,000
customers with water from wells in one portion of the affected alluvial aquifer.
Various government bodies, including EPA, sampled the ground water off-post
and identified the RMA as one of three or more sources of the contamination.
The EPA lead RMA off-post remedial investigation/feasibility study (RI/FS) was
initiated in 1985 to evaluate measures to abate the threat of the off-post
contamination; the Army is conducting an RI/FS on-post and in another off-post
area. During the course of its RI/FS, EPA determined that an operable unit
should be conducted to address replacement or treatment of contaminated ground
water being used for the public water supply. Subsequent operable units may
address aquifer restoration and source control measures. The ROD for the first
off-post operable unit was signed June 4, 1987.
In March 1986, the Army agreed to transfer $1 million to EPA for use in
responding to the contamination. The publicly used ground water is currently
being treated prior to consumption through a temporary carbon filtration system
that will operate until the permanent system selected by the ROD is in place.
The temporary action is funded by the Army, and it is being conducted by the
local government through a cooperative agreement with EPA. On September 28,
1986, the Army provided EPA with an additional $6 million for response purposes
pursuant to the existing enforcement agreement and on September 16, 1987,
another $300,000 was provided in another amendment. Under a separate September
18, 1987 agreement, the Army provided another $6 million for the long-term (25
years) operation and maintenance (O&M) of the permanent treatment system,
$975,000 for reimbursement of the private well connection costs, and $300,000
for the construction of the permanent system. Total Army funding thus far
totals $14.575 million. If EPA identifies other parties potentially responsible
for the contamination, it will attempt to recover remaining response costs from
335
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
them. EPA may also seek additional funding from the Army, under limited
circumstances.
In 1986 through 1988, all interested owners of off-post private wells were
connected to the public water system when EPA determined that contamination in
the alluvial aquifer exceeded Federal limits and posed a threat: to public
health.
Description of Site Work
Ground-water sampling results collected from various investigations through
1986 indicated the presence of large areas of contaminated water off-post in
south Adams County. VOCs were present in the highest concentrations, and
detectable levels of contamination were noted in municipal wells. The off-post
RI indicated that the contamination was migrating in the ground water in the
alluvial aquifer, the primary drinking source for about 30,000 residents.
Exposure to VOCs could result from routine domestic use of water, ingestion,
inhalation (e.g., during showering), and dermal contact.
Description of Feasibility Study
The FS evaluated 10 alternative remedies to abate the threat of
contamination in the drinking water in the EPA off-post study area. To evaluate
the 10 alternatives, EPA classified alternatives according to the extent to
which a given alternative would approach, attain, or exceed applicable or
relevant and appropriate requirements (ARARs). The FS identified a range of
potential ARARs, including the Safe Drinking Water Act (SDWA) Maximum
Contaminant Levels (MCLs), Maximum Contaminant Level Goals (MCLGs), Water
Quality Criteria (WQC), and National Emission Standards for Hazardous Air
Pollutants (NESHAPS) for vinyl chloride. EPA also identified a number of the
State standards as ARARs for the operable unit. In accordance with EPA policy
at the time of the FS, EPA designated MCLs as the ARARs that the selected remedy
for ground-water remediation must attain. EPA expects that the MCLs will drive
the design and operation of the remedy.
EPA reviewed the following 10 alternatives by evaluating their
effectiveness, the engineering of the proposed response approach, arid cost:
(1) No action;
(2) Alternative water supply;
(3) Air stripping of VOCs;
(4) Air stripping of potential semi-volatile organic
compounds;
(5) Air stripping of VOCs with off-gas treatment;
(6) Air stripping of potential semi-volatile organic
compounds with off-gas treatment;
336
-------
Progress Toward Implementing Super-fund: Fiscal Year 1987
(7) Granular activated carbon (GAC) treatment;
(8) Air stripping with off-gas treatment for two
wells; GAC for five wells;
(9) Continued use of GAC system leased for removal
action; and
(10) Blending.
EPA published three fact sheets on the site during 1986 and held press
conferences to keep the public informed of remedial progress. EPA also attended
five public meetings and held a public comment period on the draft RI/FS.
Community reaction to EPA's preferred alternative (discussed below) was
favorable.
Description of Selected Remedy
The recommended remedy is a GAC treatment system with the regeneration of
spent carbon (Alternative 7) . This cost-effective alternative effectively
mitigates and minimizes threats to public health. EPA found the chosen remedy
to be the most favorable when comparing alternatives on the basis of technology,
reliability, permanency, cost, and effect on the public health.
The GAC system will treat contaminated water from the South Adams County
Water and Sanitation District (SACWSD) supply wells prior to its consumption as
drinking water. The GAC system will remove the substances of primary concern
from the drinking water to levels that will assure protection of human health
and attain ARARs, The system will require future operation and maintenance
activities to ensure its continued effectiveness.
In the event that vinyl chloride levels increase above the standard and
require remediation, the GAC system will be designed so that an air stripper may
be added to remediate the vinyl chloride. Spent carbon from the GAC system will
be regenerated at an incinerator in compliance with sections 3004 and 3005 of
SDWA.

PHOENIX-GOODYEAR AIRPORT SITE
SECTION 16 OPERABLE UNIT
GOODYEAR, ARIZONA
HRS Score: 45.91 NPL Rank: 254
Background
The Phoenix-Goodyear Airport (PGA) site is located approximately 17 miles
from Phoenix, Arizona. In 1981, the Arizona Department of Health Services
(ADHS) discovered that ground water and 18 wells in the PGA area were
contaminated by solvents, chromium and trichloroethene (TCE). Drinking water
supplies, industrial water supplies, and irrigation water come solely from
ground water that is pumped from the aquifer underlying the site area. In
addition, development by the City of Goodyear is planned for the area
downgradient from the site, and this development will include using ground-water
resources currently threatened by contamination. The site was added to the NPL
in September 1983.
An operable unit was initiated at the PGA site based on geography and the
contaminated media being addressed. The aquifer underlying the site is
separated into three units. Subunit A of the aquifer is unsuitable for drinking
water. Subunits B and C of the aquifer are potential sources of drinking water
and are hydraulically connected. Subunit A is also connected to Subunits B and
C by conduit wells and sand lenses. The Operable Unit addresses the ground-
water contamination of the upper alluvial aquifer in the southern portion of the
site. This operable unit covers 750 acres and includes the Loral Corporation
facility (formerly owned by the Goodyear Aerospace Corporation [GAG]) and the
Phoenix-Goodyear Airport (formerly owned by the U.S. Navy). Both of these
facilities are potential sources of the volatile organic compound (VOC) ground-
water contamination.
The EPA lead Remedial Investigation (RI) for the entire site was initiated
in 1984. The feasibility study (FS) for the Operable Unit was released in the
summer of 1987 and the ROD was signed September 29, 1987. Soil and soil/gas
sampling is currently being completed to characterize soil contamination at the
site. Consequently, soil and ground-water contamination beyond the area of the
operable unit will be addressed in the subsequent FS for the entire site.
EPA identified GAC and the Department of Defense (DOD) as potentially
responsible parties (PRPs) at the site. GAC has been participating in the RI/FS
process since 1984, and an Administrative Order for RI/FS activities was signed
by GAC and EPA in March 1986. The U.S. Corps of Engineers represented the DOD
on the Phoenix-Goodyear Airport Interagency Committee, which was established by
EPA to involve State and local agencies, as well as PRPs, in actions on the
site.
338
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Site Work
The RI examined ground-water contamination in Subunits A, B, and C of the
aquifer. In addition to TCE and chromium contamination, elevated levels of
compounds including 1,1-dichloroethene, chloroform, and carbon tetrachloride
were detected in the ground water at the site. Those identified as potentially
affected by contamination were wildlife near the site and the population of the
Goodyear/Avondale area. Four endangered species inhabit or migrate through the
area just south of the site. Additionally, the PGA area itself supports one of
the largest breeding dove colonies in the Southwest and is popular for dove
hunting. The RI determined that risk associated with exposure to contaminated
ground water is an excess lifetime cancer risk as high as 2 x 1CT3. Although
exposure to contamination is currently limited, future migration of contaminants
will present heightened risks.
Description of Feasibility Study
The purpose of the FS for the Section 16 Operable Unit was to remove
contaminants from the ground-water system and to limit the migration of
contaminants from Subunit A of the aquifer to Subunits B and C. The detailed
evaluation of alternatives considered CERCLA requirements that a remedial action
protect human health and the environment and permanently and significantly
reduce the volume, toxicity, or mobility of hazardous substances, pollutants,
or contaminants. The remedy selected for the Section 16 Operable Unit should
also be consistent with the final remedial action for the entire site. The
alternatives considered were grouped into three categories: ground water, water
treatment, and water end use.
(1) Ground-water Alternatives:
• No action;
• Containment with a slurry wall;
• Extraction at GAG and PGA facilities;
• Extraction from Subunit A beneath all of Section 16;
and
• Extraction from Subunit A, at an accelerated rate.
(2) Treatment Alternatives:
• Air stripping; and
• Carbon adsorption.
(All other treatment alternatives were screened out due
to performance or institutional constraints and
inability to treat expected contaminant
concentrations.)
(3) Water End-Use Alternatives:
• Ground-water recharge.
(All other water end-use alternatives were screened out
because of the high concentrations of total dissolved
salts in Subunit A water.)
339
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Federal applicable or relevant and appropriate requirements (ARARs) for the
site included the Safe Drinking Water Act (SDWA) Maximum Contaminant Levels
(MCLs) and Maximum Contaminant Level Goals (MCLGs).
EPA held a public comment period and a public meeting, and distributed fact
sheets concerning the site. During the public comment period on the FS in June
and July 1987, EPA received comments from persons residing or conducting
business in the area of the site.
Description of Selected Remedy
The entire Subunit A of Section 16 will be pumped and treated with air
stripping and reinjected into the aquifer. Water from Subunit B and C will be
pumped and treated by the Loral Corporation at historical rates that have
contained the contamination within Subunit B and C. Treatment will continue
until contaminant levels of the discharge from the treatment plant meet ARARs.
Emissions controls, such as activated carbon units, will be used to treat air
releases from the treatment facilities, and if the carbon is taken off site, it
will be disposed of at an approved Resource Conservation and Recovery Act (RCRA)
facility.
The selected remedy satisfies the requirement of reducing the mobility,
toxicity, and volume of contaminated water. It also uses a treatment technology
to the maximum extent practicable in a cost-effective manner. The remedy meets
the operable unit goals of stopping the migration of contaminants, is expected
to meet ARARs, and fulfills the preference for permanent solutions at CERCLA
sites.

OPERATING INDUSTRIES INC. LANDFILL SITE
SITE CONTROL AND MONITORING (SCM) OPERABLE UNIT
MONTEREY PARK, CALIFORNIA
HRS Score: 57.22 NPL Rank: 71
Background
The Operating Industries Inc. (Oil) site consists of a 190-acre landfill
located approximately 10 miles east of Los Angeles in Monterey Park, California.
During its operation from 1948 to 1984, the landfill accepted municipal and
industrial waste. Leachate generated at the site contains hazardous organic
compounds including vinyl chloride, trichloroethylene, benzene, and toluene.
There are approximately 53,000 residences within a 3-mile radius of the site.
The site is owned by Operating Industries Inc., the former operators of the
landfill. EPA has been conducting site control and monitoring (SCM) activities
at the site since May 1986 when Oil discontinued all activities at the site.
Hazardous wastes accepted at the landfill included water-insoluble
nondecomposable inert solids, waste-water treatment sludge from the production
of chrome oxide green pigment, and slop oil emulsion solids and tank bottom
sludges (leaded) from petroleum refining operations. Both landfill gas and
leachate are generated at the site. Leachate collected by the leachate
collection system was historically mixed with solid wastes on site but, since
1985, has been transported by EPA to a permitted off-site treatment facility.
Oil was responsible for installation of a leachate collection system,
development of an air-dike injection system to control subsurface gas migration,
installation of gas extraction wells around the perimeter of the site, and
limited site contouring and covering. Emergency actions taken by EPA included
slope stability and erosion control improvements, surface runoff and drainage
improvements, and site security. In addition, the perimeter of the southern
portion of the landfill was fenced, entrance restricted, and 24-hour security
provided.
EPA signed two RODs for continuing site control and monitoring activities
as an interim remedy until a long-term solution is developed, and for
construction of an on-site leachate treatment plant. Long-term remediation will
be addressed in a comprehensive remedial investigation/feasibility study
(RI/FS). An additional operable unit FS is currently underway for gas control.
EPA is conducting negotiations with the Oil potentially responsible party (PRP)
steering committee to have the PRPs conduct and finance RD/RA of the leachate
treatment plant and daily site control.
Description of Site Work
Although the RI for the site has not been completed, numerous site problems
include the following: hazardous leachate seepage and breakthrough on the
landfill slopes; subsurface and off-site migration of leachate; high landfill
methane levels; vinyl chloride present in ambient air emissions and in
subsurface gas on site and off site; underground fires and associated subsidence
on site; slope instability and erosion problems; surface runoff; ground-water
341
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
contamination from leachate and migrating landfill gas; and noxious and
offensive odors both on site and off site.
Description of Site Control and Monitoring Feasibility Study
Seven control systems require operation and maintenance (O&M), inspection,
and monitoring activities, as addressed in the SCM operable unit: (1) the gas
extraction and air dike system; (2) leachate collection system; (3) irrigation
system; (4) access road system; (5) storm water drainage system; (6) site
security; and (7) slope repair and erosion control. Initial screening narrowed
the detailed alternative evaluation to two remedies:
(1) Full-time SCM (Level 1) - continued SCM of the
site systems, limited to O&M of the systems
currently in place; and
(2) Full-time SCM (Levels 1 and 2) - continued SCM and
improvements to the systems.
Level 1 is considered a baseline level consisting of basic repairs, and Level
2 includes preventative maintenance.
Community involvement at the site included formation of a committee of
residents who live near the landfill. Additionally, EPA conducted community
interviews, established information repositories, distributed fact sheets, and
held public meetings to keep the community on-site activities and to discuss the
SCM and leachate management FSs.
Description of Selected Remedy
EPA recommended Alternative 2 for site control monitoring: full-time SCM
(Levels 1 and 2) . This alternative is more protective of public health and the
environment than Alternative 1 because it allows for system improvements, is
protective of human health and the environment, cost-effective, and uses
permanent solutions and treatment technologies to the maximum extent
practicable. The recommended alternative is not expected to achieve ARARs for
gas emissions but, because it is an interim remedy, this requirement can be
waived under CERCLA section 121(d).

SAN FERNANDO VALLEY AREA 1 SITE
NORTH HOLLYWOOD/BURBANK WELL FIELD OPERABLE UNIT
LOS ANGELES COUNTY, CALIFORNIA
HRS Score: 4224 NPL Rank: 343
Background
The North Hollywood/Burbank Well Field is located in the San Fernando
Valley Area 1 site, one of four NPL sites in the 112,000-acre San Fernando
Valley ground-water basin. The ground-water basin is situated in the coastal
mountain ranges within the Los Angeles Metropolitan area. The Los Angeles
Department of Water and Power (DWP) operates the well field, which provides
approximately 10 percent of DWP's total water supply to the residents of the
City of Los Angeles. Ground water from the basin can supply water to as many
as one million people and is also an important source of water for the nearby
cities of Burbank, Glendale, and San Fernando. Three other well field sites in
the basin (known as San Fernando Areas 2,3, and 4) have also been included on
the NPL.
Investigation of contamination in the Area 1 well field began in 1980 with
the discovery of trichloroethylene (TCE) and tetrachloroethylene (i.e.,
perchloroethylene or PGE) in one-quarter of DWP's wells in the basin. In July
1981, DWP and the Southern California Association of Governments (SCAG) began
a 2-year study funded by EPA. The study revealed that contamination was
spreading with the flow of ground water at a rate of nearly 300 feet per year.
Consequently, DWP began a program that involved pumping and dilution of the
contaminated water to control the spread of contamination. In 1984, the entire
Area 1 site, along with the three other well field sites in the San Fernando
Valley basin, were proposed for inclusion on the NPL.
In 1985, EPA evaluated site data and concluded that adequate information
existed to justify a Fast-Track evaluation of the North Hollywood/Burbank Well
Field. In March 1986, under a cooperative agreement with EPA, DWP prepared an
Operable Unit Feasibility Study (OUFS) to recommend an interim remedy for
mitigating ground-water migration in Area 1. The ROD for the well field
operable unit was signed August 31, 1987. A comprehensive remedial
investigation/feasibility study (RI/FS) of the entire San Fernando Valley area
is being completed to select a final remedy for all four sites.
EPA developed a list of 59 potentially responsible parties (PRPs) for the
four sites within the San Fernando Valley. The PRP facilities included
electroplating, aircraft, and light manufacturing industries. EPA plans to send
CERCLA section 104 information-gathering letters to these facilities to
determine the extent of their responsibility.
Description of Site Work
Because the OUFS for the Area 1 well field was completed prior to the
comprehensive RI/FS, the extent of contamination was based on preliminary
investigations. The RI for all four San Fernando Valley sites began in August
1987. According to the investigations, TCE is the primary contaminant, with
lesser quantities of PCE and other volatile organic compounds present in the
343
-------
Progress Toward Implementing Super-fund: Fiscal Year 1987
ground water. The highest TCE level found (1500 ppb) is 300 times the Federal
standard for the contaminant (5 ppb).
Presently, water from the 27 wells in the North Hollywood Well Field
contain TCE in levels greater than Federal and State standards and, at the
current rate of migration, water from another 5 to 10 wells may exceed
contaminant levels in the next 2 years. Under normal conditions, ground water
delivered to DWP customers does contain TCE and PCE, but at levels that do not
exceed Federal and State standards. During periods of drought and high demand,
however, DWP may be forced to provide water that exceeds standards.
Description of Feasibility Study
The objective of the operable unit FS was to identify actions to slow down
or arrest the migration of the contaminant plume at the North Hollywood/Burbank
Well Field. The selected alternative was to be used as an interim measure while
the comprehensive RI/FS is performed. After an initial screening of
technologies and alternatives based on cost and effectiveness in meeting
operable unit goals, three alternatives were retained for detailed evaluation:
(1) Ground-water extraction and treatment by aeration;
(2) Ground-water extraction and treatment by granular
activated carbon (GAG); and
(3) Ground-water extraction and treatment by aeration
combined with vapor-phase GAG.
In December 1986, EPA and DWP held a community meeting on the OUFS report
with approximately 15 residents in attendance.
Federal ARARs identified for the site included the Safe Drinking Water Act
(SDWA) Maximum Contaminant Level Goals (MCLGs) and Maximum Contaminant Levels
(MCLs). The MCLs for TCE and PCE were determined to be applicable to the
remedial action. State ARARs included California State Action Levels, which
generally parallel EPA's MCLs and MCLGs. Resource Conservation and Recovery Act
(RCRA) standards for disposal of spent carbon will be considered an ARAR.
Alternatives will comply with State air-quality standards set by the South Coast
Air Quality Management District in Los Angeles.
Description of Selected Remedy
EPA determined that the most cost-effective interim remedy is ground-water
extraction and treatment by aeration, combined with vapor-phase carbon
adsorption (Alternative 3) . Although all three alternatives were considered
capable of meeting ARARs and CERCLA requirements that a remedy protect human
health and be technically implementable, public concern over air emissions
caused EPA to select aeration with carbon adsorption as a remedy. The aeration
facility will be constructed by the DWP under a cooperative agreement with EPA.

SAN GABRIEL AREA 1 SITE
INITIAL REMEDIAL MEASURES
EL MONTE, CALIFORNIA
HRS Score: 4224 NPL Rank: 341
Background
The San Gabriel Area 1 site is one of four sites (Areas 1 through 4)
located in the San Gabriel ground-water basin in Los Angeles County, California.
All four sites were found to have contaminated ground water with chlorinated
hydrocarbons. Area 1 contains a plume of ground-water contamination located
primarily underneath the City of El Monte.
In 1980, the State of California began an extensive well-water testing
program in the San Gabriel basin. Results indicated that numerous wells were
contaminated with trichloroethylene (TCE), tetrachloroethylene (i.e.,
perchloroethylene or PCE), and other chlorinated hydrocarbons. Although many
water companies have been affected by the contaminated water, only three small
water companies in the City of El Monte have been unable to provide water that
meets Federal and State drinking-water standards. The larger water companies
affected by the contamination have taken interim actions, such as shutting down
the contaminated wells or blending water, to reduce contaminant concentrations.
The three water companies, Richwood, Rurban Homes, and Hemlock, have no
alternate water supplies.
A Focused Feasibility Study (FFS) that was completed in December 1983
identified an initial remedial measure (IRM) to resolve the water companies'
contamination problem before a long-term solution to ground-water contamination
in the San Gabriel basin is implemented. The objective of the IRM was to ensure
that all residents affected by ground-water contamination in San Gabriel Area
1 are provided with safe drinking water. A ROD signed in May 1984 selected
air-stripping treatment as the most cost-effective IRM for the three companies.
During a Pre-Design Study initiated in July 1984, however, it became apparent
that the cost to construct the remedy would be much higher than estimated in the
FFS. Consequently, the conceptual design and costs for the next most cost-
effective alternative, carbon adsorption treatment, were revised.
In October of 1985, the California State Assembly passed Senate Bill 1063
authorizing State funding for treatment systems and directing the California
Department of Health Services (DHS) to pay for the carbon adsorption systems for
20 years. The bill allowed EPA to reconsider its decision regarding the
feasibility of the carbon adsorption alternative due to its high operation and
maintenance (O&M) cost.
DHS used State funds to construct an emergency connection from Richwood to
the San Gabriel Valley Water Company in early 1986. Conceptual designs and cost
estimates for carbon adsorption systems were completed, and cost estimates for
the air-stripping alternative were updated in June 1986. Given the new cost
estimates, EPA determined that carbon adsorption was the most cost-effective
alternative. The ROD for the IRM at Area 1 was signed September 30, 1987. An
overall area-wide remedial investigation/feasibility study (RI/FS) for the San
Gabriel Area (Sites 1 through 4) is being conducted.
345
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Site Work
Sampling studies in Area 1 indicated that the contaminant level of PCE in
the Richwood Mutual Water Company North Well was approximately 25 times State
action levels and, since that time, Richwood's wells have been shut down. The
Rurban Homes Mutual Water Company's wells showed PCE concentrations just above
DHS action levels in January 1985. Monthly sampling in 1987, however, has since
detected PCE levels below action levels; the reason for this drop is unknown.
Sampling data for 1987 shows PCE levels in Hemlock's two wells ranging from less
than 10 ppb to as high as 150 ppb, far above the recommended limit of 1 ppb.
Description of Feasibility Study
The IRM alternatives presented in the 1984 ROD were:
(1) Treatment of well discharge with air-stripping system;
(2) Dissolution of water companies and merger with another
water company;
(3) Provision of bottled water;
(4) Connection to metropolitan water district; and
(5) Treatment of well discharge with carbon
adsorption.
Further evaluation of the alternatives and the development of more refined
estimates of water use, has led to cost-estimates different from those initially
identified. The non-cost factors associated with each of the IRM alternatives
were also reevaluated.
Federal applicable or relevant and appropriate requirements (ARARs)
identified for the site include the Safe Drinking Water Act (SDWA) Maximum
Contaminant Level Goals (MCLGs) and Maximum Contaminant Levels (MCLs). Also
taken into consideration were Health Advisories issued by EPA Office of Drinking
Water and DHS action levels. ARARs for the air-stripping alternative included
State Air Quality Management Rules and the Clean Water Act (CWA) National
Pollution Discharge Elimination System (NPDES). State Air Quality Management
Rules were also an ARAR for the carbon adsorption alternative.
A public comment period on the draft report for the IRM was scheduled in
October 1986. A fact sheet on the report was distributed and the report was
made available at three information repositories. No public meeting was
scheduled during the public comment period; however, two comments were received
on the selection of alternatives.
346
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Selected Remedy
On the basis of the revised cost-effectiveness analysis, EPA selected
carbon adsorption treatment of well discharge from Richwood and Rurban Homes as
the IRM alternative (Alternative 5). The remedy, which also includes upgrading
Hemlock's current carbon adsorption system, was selected because it is
protective of human health and the environment and meets the CERCLA preference
for treatment technologies. Under this alternative, the financial impact on the
water companies' water users is mitigated through the State's funding of O&M.
The alternative presents less potential visual and noise impact on the community
than other options and, continued use of the water companies' wells, may
contribute to reduced migration of contamination in the ground-water plume.
Due to the recent drop in contamination levels in Rurban Home's wells, the
treatment system will not be implemented if continued monitoring shows the
contaminant levels remaining below action levels. In addition, in response to
a request by Hemlock, its present system will not be upgraded at this time.

STRINGFELLOW ACID PITS
EARLY IMPLEMENTATION ACTION
GLEN AVON, CALIFORNIA
MRS Score: 61.40 NPL Rank: 32
Background
The Stringfellow Acid Pits site is a hazardous waste disposal facility in
Riverside County, 5 miles northwest of Riverside, California. The Stringfellow
Quarry Company operated the facility from August 1956 to November 1972, when it
was voluntarily closed. During operations, the company deposited approximately
34 million gallons of industrial wastes, primarily from metal finishing,
electroplating and DDT production, in evaporation ponds over 17 acres of the
site. Site operations also included spray evaporation of pond contents to
accelerate volume reduction. In 1969 and 1978, excessive rainfall caused the
disposal ponds to overflow. The overflows extended across a highway into the
nearby community of Glen Avon.
In 1980 and 1981, the Santa Ana Regional Water Quality Control Board
(RWQCB) implemented an Interim Abatement Program, including removal of liquids,
capping, and installation of monitoring wells and a leachate collection system.
In 1983, EPA initiated a "Fast Track" remedial investigation/feasibility study
(RI/FS) to identify alternatives for ground-water extraction and off-site
disposal. The selected interim remedy included the installation of an on-site
treatment facility and additional interceptor and monitoring wells. The ROD for
the interim remedy was signed July 1984.
The California Department of Health Services (DHS) is conducting a
complete RI/FS to identify and evaluate alternatives for final site cleanup.
The FS report is expected to be completed by mid-1988. EPA and DHS have
identified two early implementation actions (EIAs) to be conducted before the
comprehensive RI/FS is completed. The decision on the EIAs was presented in the
ROD signed June 25, 1987.
In April 1983, EPA and the State of California filed a civil suit in U.S.
District Court against 18 generators of the Stringfellow wastes, four
transporters, and nine owners and operators of the disposal facility. EPA has
given these potentially responsible parties (PRPs) the opportunity to design and
implement the EIAs subject to EPA and DHS approval and oversight, but has not
been successful in reaching an agreement with any of them.
Description of Site Work
The 1984 EPA lead RI revealed that ground water beneath the site is heavily
contaminated with metals, sulfates, nitrates, fluoride, chloride, and a variety
of organics. Ground-water samples also indicated elevated levels of radiation,
although no relationship has been found between the Stringfellow wastes and
radiation in private community wells. Most recent RI activities Indicated a
zone of contamination 900 feet wide, extending 2 miles downgradient from the
site. Additional ground-water monitoring detected site-related contaminants in
a plume moving downgradient from the site into the lower canyon area and the
348
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Glen Avon community, indicating the need for additional actions to increase the
effectiveness of the current interim measures.
The primary concern is human exposure to ground water through consumption.
If the contaminant plume spreads further into the downgradient regional aquifer,
it could contaminate the drinking water supply wells in Glen Avon and
surrounding areas as well as those wells used for industrial and agricultural
purposes. Another significant exposure potential is through contact with
surface water on site and with upgradient water running on the site, especially
during large storms. This exposure potential is limited although it can be
decreased further by improving surface drainage, especially in the upgradient
areas.
Description of Feasibility Study
Based on the initial findings of the RI, the following objectives have been
identified for the final remediation process:
• Prevent further plume migration and contamination by
isolation and/or treatment of the contaminated
soil/water mixture;
• Redirect runoff and run-on to prevent surface-water
contamination;
• Prevent site air emissions that may adversely affect
public health or the environment; and
• Manage the site area to prevent direct contact.
DHS performed an assessment of 86 potentially applicable technologies.
Remaining technologies were compiled into remedial action alternatives, which
were screened for compliance with CERCLA requirements and the above objectives.
Except for the "no action" alternative, all of the remaining alternatives
included the following two actions:
(1) Diversion of upgradient surface waters by means of new
peripheral channel; and
(2) Mitigation of the downgradient contaminated plume by
installing a ground-water barrier system;
These actions, which should be implemented as soon as possible, were designated
as potential EIAs. Also considered as a potential EIA was the following action:
(3) Alternative 2, with treatment of extracted ground
water.
DHS identified Clean Water Act (CWA) discharge requirements and Santa Ana
Watershed Project Authority (SAWPA) pre-discharge treatment requirements as
applicable or relevant and appropriate requirements (ARARs) for the site.
349
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Although no comment was received from the public regarding selection and
implementation of the EIAs, the EIAs are consistent with prior remedial actions
that the community has supported. Several public meetings have been held during
the ongoing RI/FS process.
Description of Selected Remedy
The EIAs selected for the site are Alternatives 1 and 3, which include the
following actions:
• Installation of a peripheral channel around the north
end of the original site to direct upgradient surface-
water runoff; and
• Installation of a. ground-water barrier system in the
lower canyon area and treatment of extracted ground
water, if necessary, with discharge to a publicly-owned
treatment works.
In addition, based on the July 1984 ROD, the existing water channels will be
extended southward to discharge surface water to Pyrite Creek.
These actions will increase the effectiveness of the existing remedial
system and are consistent with both past actions and the final remedial actions
to be chosen after completion of the comprehensive RI/FS. These actions have
community support, have no significant adverse environmental effects, and will
help to protect public health and the environment. The State concurs with the
remedy.

COLBERT LANDFILL SITE
COLBERT, WASHINGTON
MRS Score: 41.59 NPL Rank: 356
Background
The Colbert Landfill is a 40-acre sanitary landfill located in the town of
Colbert approximately 15 miles north-northeast of Spokane, Washington. The area
is semi-rural with a population of about 1,500 people within a 3-mile radius of
the landfill. Since 1968, the landfill received both municipal and commercial
wastes until it was filled to capacity; it is no longer receiving waste. During
the years from 1975 to 1980, a local electronics manufacturing company, Key
Tronic Corporation, dumped spent organic solvents at the site, mainly methylene
chloride (MC) and 1,1,1-trichloroethane (TCA), at an average rate of several
hundred gallons a month. During the same period a nearby military facility,
Fairchild Air Force Base, also disposed of various solvent wastes at the site.
Other parties that disposed spent solvents at the site may be identified.
In 1980, following complaints by nearby residents of chemical disposal in
the landfill, the Spokane County Utilities Department initiated an investigation
and sampled nearby private wells. Results indicated that some wells were
contaminated with TCA. The Phase I study of the Spokane County investigation
recommended a ground-water monitoring program, based on a review of existing
information on the site and field study. Phase II studies carried out in 1982
involved installation of monitoring wells, injection tests, and ground-water
sampling and analysis. In August 1983, EPA placed the Colbert Landfill site on
the National Priorities List (NPL). The EPA identified Spokane County, Key
Tronic Corporation and Fairchild Air Force Base as potential responsible parties
(PRPs) .
The remedial investigation/feasibility study (RI/FS), jointly conducted by
the Washington Department of Ecology and EPA, was completed in May 1987. The
ROD signed September 20, 1987 selected an interim final remedial action for the
site, because extraction and interception well-systems will be in operation for
decades before remediation is complete, and changes in the selected action may
be required during that period.
Description of Site Work
The main contaminants detected in the ground water during the RI were six
volatile organic chemicals. The only contaminant of concern detected in any of
the soil samples was MC. Detectable levels of "soil gas" contamination were
found over much of the area where ground-water contamination had been found.
The RI results suggested that substantial quantities of contaminants remain at
the bottom of the aquifers in the form of dense, nonaqueous phase liquids, i.e.,
relatively undiluted chemicals existing as separate liquids rather than in
solution in the ground water.
351
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Description of Feasibility Study
Three remedial alternatives were developed and evaluated in the FS:
(1) No action;
(2) Alternate water supply, point of entry treatment,
and ground-water extraction; and
(3) Treatment and discharge (using various
technologies for each) plus an expanded water
system.
Each of these alternatives was considered separately in three geographic
portions of the site; the southern area, where the plume in the upper aquifer
is advancing; the western area, where the plume in the lower aquifer is the
major concern; and the eastern area, where the plumes appear to originate,
probably from accumulations of concentrated solvent fluids. About 90 different
technologies were screened and evaluated, resulting in detailed evaluation of
12 remedial alternatives in the southern area, seven in the western area, and
seven in the eastern area.
The major Federal applicable or relevant and appropriate requirements
(ARARS) identified include the following: the Resource Conservation and
Recovery Act (RCRA), the Safe Drinking Water Act (SDWA), the Clean Water Act
(CWA), and the Clean Air Act (CAA). In addition, the selected remedy has to
satisfy numerous Washington State laws and regulations that have been
identified. The FS showed that all of the deep-well extraction, treatment, and
disposal alternatives are acceptable, as long as performance standards are met.
Description of Selected Remedy
This interim final remedial action addresses management of the migration
of contaminants using a ground-water interception system in the southern and
western areas, and attempts source control in the eastern area through
extraction of ground water with the highest contaminant concentrations. All
extracted water will be treated to specified performance standards, monitored
to assure compliance, and properly discharged. The remedy is designed:
• to prevent further spread of contaminated ground water in
two aquifers by installing and operating interception wells
and treating the extracted ground water;
• to remove contaminated materials by installing and operating
extraction wells in the area where the plumes originate and
treating the effluent; and
• to provide an alternate water supply system to any residents
who are deprived of their domestic supply by demonstrated
contamination from the landfill or due to the action of the
extraction systems.
352
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
In order to provide the potentially responsible parties a sufficient degree
of latitude in selecting a technology required to achieve the desired
performance, the ROD did not specify a particular technology. This desired
performance is defined as treating wastewater effluent to or below the Maximum
Contaminant Levels (MCLs), or a similar health based level (the 1CT6 risk level
for carcinogens) for contaminants for which MCLs have not been determined.
Treated water effluents will also be monitored to assure adherence to
performance standards. Treated water discharge shall at all times be consistent
with Federal and Washington State laws.
The selected alternative meets CERCLA requirements because it permanently
reduces the toxicity, mobility, or volume of the contaminants. The selected
alternative also is expected to meet ARARs, is cost-effective, and uses
permanent remedies and treatment to the maximum extent practicable.

that using the January 1, 1987 reference date may not
account for all the time gained or lost in the life cycle
of a given project. However, EPA chose the January date
because it marked the first complete update for RI/FS and
RA projects after the hiatus between Superfund
authorizations. Choosing an earlier date would have
included time lost due to circumstances beyond EPA's
control.
The estimated year and quarter of completion
as of September 30, 1987, the end of the fiscal year.
Status of the activity as of the end of FY87. On-schedule
activities are designated by an equal sign (=) .
Activities behind schedule are designated by a numeral
indicating the number of quarters the activity is behind

Review of the Fiscal Year 1987
Superfund Report £o Congress
FROM: ^yjohnC"~*Martin
( inspector General (A-109)
TO: William K. Reilly
Administrator (A-100)
SCOPE AND OBJECTIVES
This report presents the results of our review of the Environmental
Protection Agency's (EPA) Annual Report to Congress on Progress Toward
Implementing Superfund: Fiscal Year 1987 (Annual Report). The objectives of
our review were to determine whether the Annual Report is reasonable and
accurate, as required by Section 301(h)(2) of the Comprehensive Environmental
Response, Compensation, and Liability Act (CERCLA).
We conducted our review between January 15, 1988, and January 23, 1989, at
EPA Headquarters and in EPA Regions 2, 5, 8, and 9. We completed most of our
work by August 1988, when EPA sent the Report to the Office of Management and
Budget (OMB) for review. However, we also reviewed the final changes made to
the Report in January 1989, after OMB's review had been completed.
Our work focused on Fiscal Year 1987 (FY87) activities. Numerous auditors
familiar with the Superfund program reviewed the entire Annual Report to
determine if there were any sections which did not appear to be reasonable and
accurate. We performed detailed audit work in EPA Headquarters and Regions 2,
5, 8, and 9 to verify the accuracy of key information presented in Chapters 2.0,
"Responding to Releases of Hazardous Substances", and 7.0, "Development and
Evaluation of Permanent Treatment Technologies". These chapters of the Annual
Report addressed five of the seven areas specifically required by Section
301(h)(l) of CERCLA. We did not perform detailed audit work on Chapter 13.0,
"Executive Branch Estimate of Resources Needed to Complete CERCLA
Implementation", another area which CERCLA required, since the Agency provided
only current budget figures in response to this requirement. Finally, we
reviewed Appendix C, "Detailed ROD Descriptions", to determine if the summaries
presented were reasonable.
Throughout the course of our review, we brought the concerns which we
identified to the Agency's attention. The Agency corrected most of these
concerns.
Except as noted below, our work was performed in accordance with the
Standards for Audit of Government Organizations, Programs, Activities and
391
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
Functions (1981 revision) issued by the Comptroller General of the United States.
We did not perform a full scope audit to determine if the Superfund program is
achieving the results required by CERCIA, nor did we perform extensive tests to
determine if internal controls are adequate. We performed audit work we believed
necessary to determine if key information included in the Annual Report is
reasonable and accurate. Furthermore, for the items not tested, based on our
review, nothing came to our attention which warranted more detailed audit work
than that described in the DETAILS OF REVIEW section.
SUMMARY OF RESULTS
We found that some of the areas presented in the Annual Report, such as the
information presented in Chapter 7.0 on the Superfund Innovative Technology
Evaluation (SITE) Program, were generally reasonable and accurate. However,
other important areas of the Report included information which was not reasonable
and accurate, and some information was not as complete as it could have been.
In addition, the process the Agency used to prepare the Annual Report was not
completely effective.
Certain information presented in Chapter 2.0 of the Annual Report was not
reasonable or accurate. First, program accomplishments figures were frequently
inaccurate because the Agency used Headquarters information systems which were
not reliable to prepare its Report. Many of their figures did not agree with
the corresponding information secured from Regional systems, and significant
portions of the Regional claims were not supported by valid source documents.
In addition, Appendix D of the Annual Report, which shows the status of Remedial
Investigations/Feasibility Studies (RI/FS) and Remedial Actions (RA) on September
30, 1987, identifies delays which occurred since January 1, 1987, but does not
identify any delays which may have occurred prior to that date.
The Agency's official definitions of two terms used in the Annual Report,
the "start" of key program activities and "operable unit", may lead the reader
to believe that more on-site work was done, at a greater number of facilities,
than actually occurred. Specifically the Agency defines "start" as a financial
transaction, i.e., when funds are obligated to begin work. No actual on-site
cleanup work needs to be performed to qualify as a "start", and many months can
elapse between the obligation of funds and the commencement of on-site work.
In addition, EPA frequently divides Superfund "sites" into "operable units" to
more easily manage the cleanup process. One site can have ten or more operable
units, creating difficulty in correlating the number of cleanup actions taken
during FY87 with overall cleanup progress at Superfund sites.
In two areas of the Annual Report, we believe the information presented was
not as complete as it could have been. First, CERCLA requires the Agency to
provide an estimate of the resources needed to complete implementation of the
statute. In response, however, EPA provided only the Agency's FY87 through FY89
budget figures. Second, we do not believe that the level of detail provided in
the feasibility studies descriptions is sufficient, so that the reader can fully
understand and appreciate EPA's decision-making process.
Finally, the process used to prepare the Annual Report was not fully
effective. For example, the Report coordinator's resources were limited, and
392
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
key end of fiscal year data was still uncertain and, in some cases, unavailable
for our review until April 1988. As a result, the Annual Report was not
completed until January 1989, even though it was due to Congress on January 1,
1988.
The details of our scope, methodology, and results of review for the
concerns summarized above are presented in the DETAILS OF REVIEW section of our
report.
DETAILS OF REVIEW
Annual Report Chapter 2.0 - Responding to
Releases of Hazardous Substances
As previously stated, some of the information in the Annual Report was not
finalized until January 1989. In order that our review would not delay the
Report any further, we began our field work by using a January 1988 draft, and
used updated drafts as they became available. We identified the types of
information included in the Report, and specifically focused our field work on
those items CERCLA required. We then selected four Regions in which to perform
our detailed audit work: Regions 2 and 5 because of their heavy volume of
Superfund activity; and Regions 8 and 9 because of their significantly lower
volume. Recognizing Regional differences, we hoped in this manner to obtain a
balanced, nationwide perspective in our review.
We initially planned to select a sample of cases for review from the
Headquarters information systems being used to prepare the Annual Report. In
early December 1987, we began requesting details on which systems were being
used. As of January 15, 1988, when we began our review, the Report coordinator
could not tell us all of the systems that would be used to provide input.
Therefore, because we did not have a universe of cases from Headquarters records
from which to select a sample, we obtained FY87 information directly from the
EPA Regions. Regional officials provided this information from a variety of
computerized and handwritten systems, and stated that it was the most accurate
available.
We first verified the accuracy of the Regional numbers by interviewing
Regional staffs and reviewing source documentation. In some cases, we reviewed
100 percent of the actions; however, if the number was prohibitively large, we
randomly selected a sample for review. We also selectively reviewed a small
number of end of year actions to determine whether there existed instances in
which Superfund accomplishments were merely "paper transactions" and no on-site
work was actually performed. We did not perform a statistical sample; therefore,
the results of our review should not be projected throughout EPA.
Although the Annual Report shows totals by Region for Removal Starts and
Removal Completions, it shows only nationwide totals for the other major
Superfund activities we reviewed. The Report coordinator provided us with
Regional information on these other activities late in our review. Therefore,
at the conclusion of our field work, we compared the totals provided by the
Regions to those provided by the coordinator. We could not make this comparison
393
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
earlier because, in most cases, the Report coordinator was unable to provide the
Regional details until April 6, 1988.
Although we cannot state conclusively what the correct figures are, it is
evident from our work that some of the information presented in this Report
chapter is not completely reliable. In virtually every case, the total
accomplishments figures included in the Annual Report did not agree with Regional
records (see Exhibit 1 at the end of this report). And, as Exhibit 2 shows, 30
percent of removal activities and 13 percent of remedial activities claimed by
the Regions were not supported by valid documentation in the Regions' files.
Specifically, in many cases the Regional officials could not provide any source
document clearly showing that the accomplishment claimed actually occurred in
FY87 ("source document not located"). In a number of other cases, the documents
provided by Regional officials showed that, according to Agency definitions, the
accomplishment should have been claimed in another fiscal year ("invalid FY87
actions").
Removal Starts and Completions
The Annual Report showed a total of 97 Removal Starts for Regions 2, 5, 8,
and 9, while these Regions reported 107 Removal Starts to the auditors. The
total of 75 Removal Completions in the Annual Report was less than the total
reported by the Regions. We sampled 32 starts and 18 completions and found that,
according to Agency definitions, 28 starts and seven completions (70 percent)
were supported as valid FY87 actions. (Figures 1 and 2 below.)

forced to curtail our review to keep pace with the Agency's early schedule
for Annual Report issuance.
Preliminary Assessments and Site Inspections
The Annual Report included 1,925 Preliminary Assessments (PA) as completed
in FY87. The four Regions which we reviewed reported that 1,958 PAs were
completed. In addition, the Annual Report indicated that 514 Site Inspections
(SI) were completed in FY87, while these Regions reported 518. Of the 36 PA
completions and 40 SI completions we examined, 26 PA and 33 SI completions (78
percent) were valid FY87 actions. Figures 3 and 4 below provide the detailed
results of our review.

Remedial Investigations/Feasibility Studies
The Annual Report included 100 RI/FSs in FY87 for the four Regions we
reviewed. However, these Regions reported only 96 RI/FS starts to the auditors.
We sampled 62 RI/FSs and found 55 (89 percent) were valid FY87 actions. (Figure
5 below.)

Records of Decision/Selection of Remedy
We found that the number of Records of Decision (ROD) which the Annual
Report indicated were signed in FY87 was almost identical to the figure presented
by the Regions. The Agency reported 40 completed RODs for the Regions which we
reviewed, while these Regions reported 39. We reviewed the 39 RODs and found
that only one was not a valid FY87 action.
Remedial Designs and Remedial Actions
Our scope of review for these two actions included Regions 2, 5, and 8 (due
to time constraints, we could not complete field work in Region 9). The Annual
Report included 47 Remedial Design (RD) starts, compared to 39 reported to the
auditors by the three Regions. The Annual Report stated that 26 RAs were started
in FY87, while the three Regions reported 21 RA starts. Twenty-one of the 24

Additional Comments
During our review, we also identified concerns with the Annual Report in
such areas as definitions of terms and RI/FS timeframes. Further, a recent
Office of Inspector General (OIG) "Capping" Report titled EPA, Office of the
Inspector General Audits of Superfund Cooperative Agreements for Fiscal Years
1985 through 1987 (Audit Report No. E5eE8-09-0018-80838), dated March 29, 1988,
consolidated the results of numerous OIG reviews and pointed out many of the same
concerns that we are reporting.
The Annual Report includes information on the number of "starts" for various
activities. During our review we found that there is confusion among Agency
personnel on how a "start" is defined. The Agency officially defines "start"
as a financial transaction, i.e., when funds are obligated to perform the
activity. It is important for the reader to understand that under this
definition, no actual on-site work needs to have begun to officially qualify as
a start. Our review of Regional records showed that for many "starts", only
funding transactions occurred during FY87. So although these met the Agency's
definition, no actual on-site work took place. For example, three of the 42
397
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
RI/FS starts and three of the ten RA starts which Region 5 reported were for
funding documents prepared in September 1987, but no on-site work had begun at
the time of our review in February 1988. The OIG "Capping" Report discussed the
same condition. Further, while this definition may be widely known at
Headquarters, many Regional officials were not aware of it. This caused problems
in our review, because when questioned, Regional officials frequently had to ask
the auditors to define a "start" before they could give us any information.
We believe that it is important for the reader to fully understand the
Annual Report's discussion of "operable units", and the implications this
recordkeeping method has for overall Superfund accomplishments. EPA frequently
divides Superfund "sites" into "operable units" to more easily manage the cleanup
process. Each of these operable units (OU) may address a different problem at,
or a different portion of, a site. For example, one site in Region 8 had four
operable units. An RI/FS was completed on one OU during FY87, and RI/FSs were
in process on the other three OUs. These three OUs will be reported as
completions in future years, but they all pertain to that one site. At another
Region 8 site, records showed that as many as 11 OUs existed. Five of the seven
Region 8 RODs signed during FY87 were for OUs at this one site. Because EPA uses
this method of recordkeeping, it is difficult to correlate the number of actions
(RI/FSs, RODs, etc.) taken during FY87 with overall cleanup progress at Superfund
sites.
Appendix D of the Annual Report shows the status of active RI/FSs and RAs
on September 30, 1987. This table shows the planned completion date as estimated
on January 1, 1987. However, the table may not show any previously published
schedules for RI/FSs and RAs. Therefore, if a project will not meet a previously
published schedule, the table will not reveal this fact. Section 2.4 of the
Annual Report states that EPA chose the January 1, 1987, date because it marked
the first update for RI/FS and RA projects after the hiatus between Superfund
authorizations. Further, EPA officials believed that choosing an earlier date
would have included time lost due to circumstances beyond EPA's control.
However, regardless of what may have caused the delays, EPA is not providing the
precise information required by CERCLA Section 301(h)(1)(C).
The "Capping" Report identified the same concerns we did with the accuracy
of the Agency's Superfund information systems. For example, the CERCLA
Information System (CERCLIS) is one of EPA's key tracking systems and represents
an inventory of all potential hazardous waste sites known to EPA. OIG audits
have found that Regions are not inputting accurate and up-to-date information
into CERCLIS. Even though the Agency was aware of these problems, It relied on
CERCLIS for some information in the Annual Report.
Finally, the "Capping" Report summarized problems with documentation in
Regional files, which we also found during our review. In many cases, Regional
officials had great difficulty locating the required source documents in their
files, and in some cases they could not find these documents at all. For
example, Exhibit 2 shows that source documents could not be located for 28
percent of the removal actions and three percent of the remedial actions we
reviewed.
398
-------
Progress Toward Implementing Super-fund: Fiscal Year 1987
In discussing the discrepancies between the numbers in the Annual Report
and those that Regional officials provided to the auditors, Office of Emergency
and Remedial Response (OERR) officials stated that they considered the
differences to be minor. These officials objected to our securing information
from the Regions, stating that Headquarters management systems are the official
Agency systems to which the Regions report. Further, the Director of OERR
explained that there is only one EPA "system", and that even though some data
in this system was not accurate, the problem is data entry into the system.
Annual Report Chapter 7.0 -- Development and
Evaluation of Permanent Treatment Technologies
We reviewed the information presented in the Agency's report on the
Superfund Innovative Technology Evaluation (SITE) Program, since most of the FY87
progress made in developing and evaluating permanent treatment technologies was
centered in this program. We again used the January 1988 Report draft to begin
our field work, and reviewed updated drafts as they became available. To
determine if the information presented on the SITE Program was reasonable and
accurate, we interviewed officials from the Office of Solid Waste and Emergency
Response (OSWER) and the Office of Research and Development (ORD), who jointly
administer the program. Additionally, we visited ORD personnel at the Hazardous
Waste Engineering Research Laboratory, who are responsible for the technical
aspects of the field demonstrations, and reviewed available files and source
documentation. Based on our review, we believe that the information presented
on the SITE Program is generally reasonable and accurate.
Annual Report Chapter 13.0 -- Executive Branch
Estimate of Resources Needed to Complete CERCLA Implementation
We did not perform in-depth audit work on this chapter of the Annual Report,
because it consists of FY87 obligations, the resource estimates from the FY88
Operating Plan, and the Agency's budget request for FY89, all of which is readily
available information. We wish to emphasize that the figures presented are not
estimates of the exact Agency needs for completely accomplishing the requirements
of CERCLA.
The language of CERCLA suggests that Congress may have wanted estimates in
the Annual Report for the total cost of completely implementing the statute.
Although some projections beyond FY89 were included in one of the last drafts
of the Annual Report, they were removed during the Agency review process.
During the Agency's internal review of the Report, the Office of General
Counsel commented that the resource projections in Chapter 13 do not go as far
as the statute requests. Further, the Office of Policy, Planning and Evaluation
recommended a more comprehensive approach for future reports.
We are not aware of any current, comprehensive study within EPA to define
the needs for accomplishing the CERCLA requirements. However, a recent report
by the Surveys and Investigations Staff of the Committee on Appropriations, U.S.
House of Representatives, points out the gap between current Superfund funding
and potential "real" needs. In a March 1988 report, Status of the Environmental
Protection Agency's Superfund Program, the committee staff stated that, using
399
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
average cost estimates to clean up National Priorities List (NPL) sites, "793
sites (would) require Federal funds ranging from about $16.7 to $23.-8 billion,
far in excess of the available $8.5 billion." The report also noted that this
estimate does not account for the possibility of hundreds of new sites being
added to the NPL.
Annual Report Appendix C -- Detailed ROD Descriptions
Historically, Congress has expressed concerns with some aspects of EPA's
decision-making processes. One purpose of the CERCLA requirement for detailed
feasibility studies descriptions was to help Congress better understand how EPA
makes decisions on Superfund sites.
The DIG believes that the level of detail contained in the Annual Report's
feasibility studies descriptions does not provide sufficient information so that
EPA's decision-making process on Superfund sites can be fully understood. The
feasibility studies write-ups generally contained a brief description of the
site, discussion of initial work done at the site, overview information about
the feasibility studies (including only one sentence summaries of the cleanup
alternatives considered), selected information on the requirements considered,
and a brief summary of the reasons for selecting the chosen remedy.
In our opinion, the descriptions of the cleanup alternatives need to be
expanded to clearly demonstrate the extent of EPA's decision-making efforts.
The ROD documents, from which the Annual Report was prepared, contain a great
deal of information on the alternatives, such as costs, benefits (including
consideration of CERCLA goals), and risks to the public health and the
environment. If the feasibility studies descriptions had contained this
additional information, it would have greatly aided the reader in understanding
how EPA made these decisions.
Exhibit 3 to our report is an example of a more complete feasibility study
write-up, which we believe demonstrates the additional information that should
have been made available to the reader.
Annual Report Preparation Process
The process used to prepare the Annual Report was not fully effective.
Although this Report was due to Congress January 1, 1988, the Report was not
completed until January 1989. Since this is the first time the Report was
prepared, some problems were expected. However, the problems which we identified
in our report seem to have been much greater than they should have been.
Part of the reason that the Annual Report encountered such difficulties is
that the Report coordinator's resources were limited. Also, at his grade level
(GS-13), he was not in a position of authority from which to command action on
the part of other organizations whose input was vital. For example, as of March
1988, the Report coordinator was still uncertain of the sources and accuracy of
many of the accomplishments figures in the Report. Despite our repeated requests
for detailed information over a period of four months, he was unable to secure
the information from the Agency offices responsible for compiling it. Further,
the coordinator had different figures for the same accomplishments, depending
on which information system he used. This should not be the case six months
400
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
after the end of the fiscal year, and is a further adverse reflection on the
reliability of the Agency's information systems.
OSWER officials stated that the main information system, CERCLIS, has been
improved for FY88. These officials believe that the use of the improved CERCLIS
will enhance the accuracy of the FY88 Annual Report, as well as decrease its
preparation time. However, this system will also contain information that is
not reliable, unless steps are taken to ensure that Regional input to CERCLIS
is accurate and complete.

EXHIBIT 3
FEASIBILITY STUDY WRITE-UP EXAMPLE
This exhibit highlights the additional information we believe should have
been included in the feasibility studies write-ups. As an example, we have
inserted this extra information, quoted from the ROD, into the existing Annual
Report text on the Laskin/Poplar Oil Site. We have indented this additional
information to identify it for the reader.
LASKIN/POPLAR OIL SITE
SOURCE MATERIAL OPERABLE UNIT
ASHTABULA COUNTY, OHIO
HRS Score: 35.95 NPL Rank: 492
Background
The Laskin/Poplar Oil Site is located west of the village of Jefferson in
Ashtabula County, Ohio. The 9-acre site is bounded by Cemetery Creek and the
Ashtabula Fairgrounds. The site was formerly used for greenhouse operations
beginning in the 1930s. Boilers were installed to heat the greenhouses in the
1950s, and tanks to hold waste oil for burning were built in the 1960s. When
the greenhouse business declined, the owner of the site began collecting,
reselling, and disposing of waste oils, much of which contained PCBs and other
hazardous materials.
The State of Ohio initiated action against the site owner in 1979 for air
and water pollution violations. In late 1980, EPA evaluated the need for
remedial action at the site and in 1982 undertook an emergency action, which
included removing 302,000 gallons of oil, treating 430,000 gallons of
contaminated water, and solidifying 205,000 gallons of sludge. Potentially
responsible parties (PRPs) removed another 250,000 gallons of oil wastewater in
1985 and 1986. EPA issued an Administrative Order of Consent to 12 PRPs between
1984 and 1986, requiring their participation in the remediation process.
EPA divided remedial activities at the site into two operable units and an
overall site investigation. The first operable unit addressed the incineration
of contaminated water and PCB-contaminated oils. The ROD for the second operable
unit, which focused on source material that remained on site, was signed
September 30, 1987. The overall site investigation still is being conducted and
will address ground water, surface water, and soil contamination as well as the
extent of dioxin contamination.
Description of Site Work
When the overall RI was initiated, the site contained 34 tanks, 4 pits, and
treatment and retention ponds. Preliminary sampling indicated large amounts of
seepage from tanks and unlined pits into surrounding soils. Investigations also
identified a threat from contaminants leaching into ground and surface water,
405
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
including Cemetery Creek, which runs into the Grand River, a source of drinking
water for 25,000 residents.
Potentially responsible parties, under consent order, initiated the study
for the second operable unit in 1985 to characterize the remaining on-site
wastes. Results indicated that waste materials still present at the site after
emergency removal actions posed a serious threat to human health and the
environment through the threat of fire and exposure to PCBs. Major contaminants
of concern at the site are PCBs, polynuclear aromatic hydrocarbons (PAHs), and
volatile organic compounds (VOCs), all of which were present in high
concentrations in waste oil and surrounding soils.
Description of Feasibility Study
The Phased Feasibility Study (PFS) for the second operable unit evaluated
remedial alternatives for the removal of source materials, including sludges,
waste oils, wastewaters, and contaminated soils (included in this operable unit
because they were a source of potential contamination of ground and surface
water). All attempts were made during the PFS to ensure that the alternatives
developed for this operable unit were consistent with final remediation for the
site. Remedial alternatives developed included the following:
Alternative 1
Under this alternative, no remedial action would be taken
at the site. The threat to public health and the
environment would remain.
Alternative 2
Alternative 2 consists of solidifying all of the liquid
wastes and placing all of the source material in a licensed
TSCA or RCRA facility as appropriate. All tanks would be
dismantled and taken off site. The pit area would be
backfilled with on-site soils and graded to preclude
ponding.
No long-term maintenance or monitoring at the Laskin/Poplar
Oil site would be required under this alternative. However,
the waste would not be treated prior to landfilling at the
licensed facility. The long-term dependability of any
landfill is unknown. The cost estimate for Alternative 2
is $4.2 million.
Alternative 3
Alternative 3 combines on-site incineration of the oils,
sludges, and source soils with off-site treatment of the
wastewaters, decontamination water, and scrubber water. The
incinerator ash and dismantled tanks would be disposed in
an off-site RCRA licensed facility. If tests indicated that
the ash could be delisted, the ash could be sent to a
406
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
sanitary landfill. The excavated pit area would be
backfilled with onsite soils and graded to preclude ponding.
This option would not require any long-term maintenance or
monitoring at the site. All source material would be
treated to the greatest extent practicable. The cost
estimate for Alternative 3 is $8.5 million.
Alternative 4
Alternative 4 utilizes off-site incineration for all oils,
sludges, and highly contaminated soils. All wastewaters and
decontamination water would be treated at an off-site
treatment facility. The tanks would be demolished and
disposed of at a licensed facility offsite. The excavated
areas would be backfilled with on-site soils and graded to
preclude ponding.
This option would not require any long-term maintenance or
monitoring at the site. All source material would be
treated to the greatest extent practicable. The cost
estimate for Alternative 4 is $12.2 million.
Alternative 5
Alternative 5 includes on-site incineration of all oils and
sludges as well as soils with greater than 25 parts per
million (ppm) PCBs or 500 ppm total halogenated organics.
The remainder of soil excavated from the tank and pit areas
would be landfilled off site at a RCRA licensed hazardous
waste facility along with all dismantled tanks. All
wastewaters, decontamination water, and scrubber water would
be treated at an off-site treatment facility. The excavated
areas would be backfilled with on-site soils and graded to
preclude ponding.
This alternative would not require any long-term maintenance
or monitoring at the site. The most highly contaminated
source material would be permanently treated. However, the
soils that would be landfilled, which comprise roughly one-
half of the source material, would not be treated. The off-
site disposal of waste without treatment is the least
favored option under SARA. The cost of Alternative 5 is
$5.8 million.
With the exception of no action (Alternative 1), all of the
alternatives would effectively and permanently minimize the
danger to the public health and the environment at the site
area through the removal of the contaminated material.
The use of an off-site landfill (Alternatives 2 and 5) is
conventional, easy to implement, and transfers the operation
407
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
and maintenance to the owner/operator of the landfill. The
most significant disadvantage of this option is that it does
not treat the contaminants so there is no reduction in
toxicity, volume, or mobility. It also may be difficult to
maintain the long-term integrity of hazardous waste
landfills as required by the U.S. EPA's off-site policy.
The off-site disposal of contaminated materials without
treatment is the least preferred option under SARA.
The off-site incineration of the source materials
(Alternative 4) offers the advantage of permanently
destroying the contaminants in the waste material and the
soils. It is a proven technology that transfers operation
and maintenance to the owner/operator of the incinerator
facility. One of the most significant disadvantages of this
alternative is implementability. The material must be
packaged in small fiber drums for transportation.
The facilities available have commitments to their regular
clients which control when and at what rates the source
material can be taken care of. In addition, a number of
off-site hazardous waste incinerators have shown a
reluctance to accept the waste material due to high levels
of lead found in some of the sludges. Transportation of the
waste to an off-site facility increases both the cost of
this alternative and the risks posed to the public by
movement of contaminated materials on the highways.
As with off-site incineration, on-site incineration
(Alternatives 3 and 5) would utilize a proven technology to
permanently destroy the contaminants in the source material.
The advantages of this alternative are that the packaging
requirements necessary for off-site incineration would be
avoided, and all material could be processed in one year or
less once the incinerator begins operation. This
alternative also meets the goal of SARA of implementing a
remedial action which incorporates treatment rather than
land disposal where practicable.
A comparison of the alternatives on the basis of
protectiveness of public health and the environment shows
that on-site and off-site incineration provide a high level
of protection. Alternatives which use a high degree of
landfilling provide an equal level of protection in the
short run. The long run dependability of landfills,
however, is unknown. There would be no beneficial impacts
associated with the no action alternative.
Any detrimental environmental effects associated with the
waste and soil removal operations would essentially be the
same for each alternative except the no action alternative.
408
-------
Progress Toward Implementing Superfund: Fiscal Year 1987
These short term negative Impacts could be minimized using
proper construction methods.
The PFS identified the Federal and State applicable or relevant and
appropriate requirements (ARARs) that the remedial action must meet, consistent
with the requirements of CERCLA. One technology considered for use on the site
was on-site containment of the wastes. However, because the RCRA land disposal
restrictions were considered ARARs, this option was not considered further.
Other ARARs identified for this site included RCRA thermal destruction,
incinerator, and off-site transportation regulations; Ohio Clean Air Act limits
on incinerator emissions; and Ohio regulations for the off-site transportation
of hazardous waste.
The State of Ohio and the U.S. EPA expressed preference for
remedial actions that would provide destruction of hazardous
constituents in lieu of transporting untreated wastes to a
RCRA approved location. Section 121(b)(l) of SARA states
"Remedial actions in which treatment which permanently and
significantly reduces the volume, toxicity or mobility of
the hazardous substances, pollutants, and contaminants is
a principal element, are to be preferred over remedial
actions not involving such treatment. The off-site
transport and disposal of hazardous substances or
contaminated materials without such treatment should be the
least favored alternative remedial action where practicable
treatment technologies are available."
Public comment on the RI/FS was received during a public availability
session, a public meeting, and through written comments. Residents and local
officials supported the selected remedy discussed below.
Description of Selected Remedy
The remedy selected was on-site incineration of all oils, sludges, and
contaminated soils and the off-site treatment of contaminated waters
(Alternative 3). This alternative uses a proven technology (i.e.,
incineration), and, because contaminated materials are destroyed, it satisfies
CERCLA1s preference for permanent solutions and use of treatment technologies.
The remedy also does not involve the off-site transportation of hazardous
materials (i.e., the oils, sludges, and contaminated soils) before treatment;
when implemented, it will provide a high level of protection of human health and
the environment. The remedy is also expected to meet all ARARs for this
operable unit. The State of Ohio was consulted during the remedy selection
process and concurred with the chosen alternative.
