Addressees
In March 1992, nearly 100 Remedial Project Managers (RPMs) and 30 EPA
Headquarters representatives met in Atlanta, GA, to participate in the Third Annual
National Meeting of RPMs. Organized by the National Association of RPMs (NARPM),
this year's meeting culminated nearly a year of incredible growth for NARPM as an
organization. In developing this Third Annual Meeting, NARPM emphasized the new
direction the Superfund program is taking. The focus of the panels and the majority of
the case studies was streamlining the Superfund process: identifying areas where
streamlining efforts have been successful, and where we have both a need and an
opportunity for improvement. RPMs also presented site- and issue-specific case studies
in the context of several of the panel discussions.
The enclosed document presents summaries of the panel discussions from this year's
meeting. The accompanying document, "Program Agenda and Abstracts", contains
abstracts from the case studies prepared and presented by RPMs from across the
country.
We hope these summaries and abstracts give you a better sense for the type of
interaction and information exchange that occurs at our annual meetings. NARPM has
received considerable praise for the content and conduct of the Third Annual Meeting.
We are currently planning our Fourth Annual meeting to be held in Seattle, Washington

Foreword
In March 1992, nearly^lOO Remedial Project Managers (RPMs) and 30 EPA
-i-icadquarters representatives met in Atlanta, GA, to participate in the Third Annual
National Meeting of RPMs. Organized by the National Association of RPMs, fondly
referred to as NARPM, this year's meeting culminated jjearly a year of incredible
growth for NARPM as an organization. Significant RPM participation during and
following the 1992 National Meeting helped us move closer to achieving the goals
established when NARPM was first organized: to develop a national vehicle for the
exchange of professional expertise and work experience among RPMs; establish
permanent panels and workgroups to explore and resolve, if necessary, recurring
site remediation issues; provide a single cohesive voice to communicate and work
with Headquarters on policy and guidance issues; and provide opportunities for
RPMs' professional growth in the areas of technology and management.
Richard Guimond, National Superfund Director, kicked off the 3rd annual
conference. During his keynote address, Guimond focused on the vital role RPMs
play in making the Superfund Program more effective, efficient and equitable.
Guimond called RPMs his "cadre of trouble-shooters" upon whom he must rely to
get feedback on whether Headquarters' policy and guidance works in the real world.
The National Meeting is one means for RPMs to interact directly with Headquarters
on such issues.
In developing this Third Annual Meeting, NARPM emphasized the new direction
the Superfund program is taking. The five standing panels from previous years ~
RI/FS, RD/RA, RD/RA Enforcement Issues, Multi-Source Contaminated Aquifers,
and Federal Facilities — convened again this year. The focus of the panels and the
majority of the case studies was streamlining the Superfund process: identifying
areas where streamlining efforts have been successful, and where we have both a
need and an opportunity for improvement. This year's agenda included several
new panels on a trial basis — Groundwater Issues, Ecological/Risk Assessment
Issues, Community Relations Issues, Expedited RD/RA, and Case Study Panels.
Each of these new panels is based on several case studies concerning a similar site
type or issue. The intent of these trial panels is to focus the discussion to address a
specific problem or issue raised by the case study(ies). RPMs presented site- and
issue-specific case studies in the context of a panel discussions.
A new and very well-received feature of this year's conference was a tour of the EPA
Environmental Research Laboratory in Athens, Georgia. Lab staff provided RPMs
with an all-day tour of the lab facilities on March 17, the day before the conference
officially began. About 25 interested RPMs witnessed field sampling demonstrations
and lab sampling techniques and visited the Ecological Support Center, where they
learned about various sediment, fish and invertebrate sampling techniques.

Recommendations of the RD/RA Panel from the NARPM Conference
There is complete agreement between NARPM and Headquarters that remedial
action completions should be emphasized and hold our attention not just as a
current initiative, but as the long term goal of our program. The RD/RA panel met
to consider a number of current topics along this line. Unfortunately, there was not
sufficient time to consider all the topics we would have liked.
The following recommendations are offered:
1. Shorten or skip RD/RA negotiations. We found that in many
circumstances, it was appropriate to consider using §122(a) of CERCLA to shorten or
eliminate the 120 day negotiation moratorium. We perceive the roadblocks to using
this tool to be:
a.	The guidance. The guidance creates more narrow circumstances than
the law itself. The guidance suggests EPA consider past dealings, lack of good faith
and on-going negotiations. NARPM believes that past dealings should include
national experience with a major PRP who's corporate philosophy is generally
known. "Good faith" is so broad, Regional attorneys will consider any gesture as
"good faith." Therefore, there is a strong bias against its use.
b.	No incentives for Regional Counsel or DOJ to speed the process.
Generally, most efforts to streamline the process over the years have been technical
in nature, or enforcement support oriented (i.e., PRP search process). Regional
Counsel and DOJ's attitude focuses on getting a (perfect and "fair") settlement, not
cleaning up a site. That focus has deterred effective project management.
l

-------
Recommendations:
a.	The guidance be revised to emphasize	
b.	Incentives be created for getting into the field, not for getting a
settlement, such as	
2. Prepare for use of enforcement tools for poor performance during
RD/RA to ensure that work proceeds in a timely and protective manner. This is the
next area of emphasis in the evolutionary chain of the program. If only a few sites of
many sites in construction have performance problems, criticism of EPA oversight
will again impede our ability to manage the program well. Use of 106 and 109
penalties should be encouraged early in the RD/RA process so that it sends the
message early to PRPs - EPA will not tolerate poor performance.
The current program weakness is perceived as a lack of descriptive penalty
policy. The current 106/107 penalty policy focuses more on schedule, with negligible
reference to performance.
Recommendations:
a.	A single CERCLA penalty policy matrix should be used for both 106 and
109. The existing 106 policy matrix is fine for 109 use, but it needs more examples on
the circumstance for use. In addition, it should contain a general description of what
makes CERCLA performance problems significant. The latter part is important to
setting the mindframe of an administrative law judge. There are many
considerations which set CERCLA apart from actions under the Clean Water Act,
RCRA, etc., such as: its higher statutory limit (25,000/day, but 75,000 for second or
subsequent violations), nature of the work (environmental uncertainties,
requirements to comply with all environmental laws, general lack of long term data
supporting violation), greater culpability of environmental contractors who qualify
for the work, in part due to their knowledge of requirements, nature of work under
a federal decree or order (not just permit violations). The RCRA penalty policy is a
good example to follow.
b.	Address perceptions that penalties are a long, involved process (109(b)
easier and faster than 109(c)). This discourages RPMs and attorneys from adding to
their workload by pursuing them. Enforcement work is generally not adequately
considered in the work load models.
c The new RD/RA Streamlining Guidance incorporates Regional
comment. Although this subject was discussed on the RD/RA panel, no further
recommendations are offered at this time.
d. Join the Program and Enforcement staff into one management system
at the Headquarters level. This is not a politically correct recommendation, but a
2

-------
very valid one from a program implementation standpoint. This recommendation
is made by various Regions when program improvements requests are made (i.e.
30/90 day studies), but categorically ignored. The arbitrary separation fails to
recognize the inherent integration of program and enforcement for all sites. At the
RD/RA phase, the separation of powers becomes more obvious, often working at
cross purposes and failing to see the "big picture", instead focusing on who's shop
the issue falls into. "Streamlining" begins at home.
e. Develop guidance on contractor disapproval. Our failure to disapprove
any contractor for poor performance reinforces the acceptability of shoddy, biased
and "nickel and dime" products. EPA's reluctance to disapprove work based on poor
performance for other projects makes good project management by an RPM almost
impossible. This is true for RD/RA as well as for RI/FS. Until EPA adopts a "get
tough" stand with PRP contractors, RPMs are left with meaningless threats and
twice the work.

Groundwater Issues
Summary Report

Panel:	Turpin Ballard, Region V
Kurt Lamber, Headquarters
Case Study Presenters
Summary
The Groundwater Issues Panel conducted at the 1992 NARPM Conference included
five case studies and a summary discussion of the presentations. The case study
presenters identified several methods for improving and streamlining Superfund
groundwater investigations.
Dennis Dalga described the use of the lead-screen auger for sampling groundwater to
depths of 200 feet or more. This sampling technique, which costs less than monitor
well installation and surpasses the capabilities of cone penetrometer sampling,
involves the use of a hollow stem auger with screen openings which allow for
sampling of the aquifer.
Mohammed Slam and Jay Silverman presented the results of their research to
determine effective sampling techniques for volatile organic compounds (VOCs) in
groundwater. After evaluating various pumps in an effort to collect sediment-free
samples, they selected a bladder pump. The sediment-free samples collected using
the bladder pump showed higher VOC concentration than the previous sediment-
laden samples collected using more conventional methods. The revised sampling
techniques resulted in a change to the selected remedy for the site. Instead of a "no
action" alternative, the analytical data now support a requirement for treatment.
The authors also noted that dioxin concentrations were lower for sediment-free
samples, indicating that much of the dioxin may have adsorbed to the sediments.
Mike Fite presented a validation study of an analytical model which was used to
develop a soil action level for polynudear aromatic hydrocarbons (PAHs). The
model generated action levels which would protect groundwater from the leaching
of PAHs from the soil. In order for the PRPs to be able to use the model, EPA
required that they collect leaching data (TCLP) from the site to demonstrate "that the
model conservatively predicted leaching. The data showed that no leaching
occurred from site soils above the risk-derived cleanup level for PAHs. This
indicated that EPA and the PRPs can now rely on a single cleanup standard for the
site rather that a leaching standard and a risk standard.

-------
In separate presentations, Claire Trombadore and Erna Acheson addressed various
issues associated with multi-source contaminated aquifers. Erna discussed and
solicited audience input for the handling of coordination problems among the
various actors within multiple regulatory and industry parties associated with a
multi-source site. Claire described a Cooperative Agreement (CA) awarded by
Region 9 to the California State Water Resources Control Board to study and address
groundwater contamination in the San Fernando Valley. The State Board had been
set up to monitor water quality in separate water quality regions within the state.
This CA concentrates responsibility for remedial efforts in one agency, focusing
attention on early remedial action rather that the time-consuming task of first
identifying and coordinating the various CERCLA, RCRA, and non-regulated
sources.
RECOMMENDATIONS
The issues raised in the Groundwater Issues Panel can be presented to existing EPA
organizations for further consideration as follows.
Groundwater Treatment Forum:
-	innovative sampling approaches
-	development of leaching-based cleanup levels to protect groundwater
Multi-source Contaminated Aquifer Workgroup:
-	use of state resources and existing regulatory structures to address multi-
source groundwater remediation

Summary Report
Moderator: Patti Collins, Region IX
Panel:	Cindy Nolan, Region V
Tinka Hyde, Region V
Marilou Martin, Region V
Rob James, Region IV ORC
Larry Starfield, OGC
Issues:
A.	EPA's role and authority to incorporate and coordinate work by other
government agencies.
B.	How and when to add PRPs that are not mentioned in the site listing.
C.	How to divide the tasks among the PRPs, including the use of partial
settlements for RD/RA.
D.	How to handle commingled CERCLA and non-CERCLA chemicals.
E.	What to do with "orphan shares" or abandoned properties.
F.	The "mine fields" of the "technical impracticability" waiver.
Discussion:
The discussion of each of these issues focused on the material needed for the
development of guidance for these sites. The guidance development is currently
underway. Each of the issues A. through E. above will be covered in the
forthcoming guidance.
The issue of "technical impracticability" waivers was discussed as a separate issue.
Across the country RPMs have seen attorneys encouraging PRPs to seek a waiver as
a way to walk away from the site. Model language proposed for inclusion in RODs
and consent decrees is not only cumbersome, but will be used by PRPs to attempt to
limit EPA's discretion in managing sites. More than on any other kind of site,
attorneys and PRPs at multi-source sites use EPA guidance and model language
against the RPM by attempting to limit EPA scope of options in managing the sites.
These attorneys and PRPs always consider EPA guidance and model language as
negotiable in their favor.
6

-------
Recommendations:
No recommendations are needed for the issues A. through E.
The panel recommends that inclusion in RODs or consent decrees of language about
the technical impracticability waiver be optional.

Anne V. Spencer (Region VIII)
Katherine Moore (Region IX)
Barbara Maco (Region IX)
Richard Procunier (RegionIX)
Our Case Study Panel Group had four rather divergent presentations.
Katherine Moore and Barbara Maco presented base closure issues in California
detailing their work on closing two of the eight military bases closing in California.
Anne Spencer detailed the importance of balancing priorities in her Superfund
work.
And finally, Richard Procunier highlighted the challenges of revegetation at
abandoned asbestos mine Superfund sites.
Each of the RPMs and sites involved faced incredible obstacles that required
ingenuity, team building and stamina to solve. Sounds just like Superfund doesn't
it?
Katherine and Barbara are facing multiple bureaucracies. In fact, they are facing tiers
of bureaucracies, each with its own special interest and unique set of problems.
They are facing the enormous challenge of coordinating all these agencies, laws and
interests into some sort of cohesive unit with the common goal of transforming
these bases to private use for the economic help of the base-dependant communities
while providing the proper environmental investigation and cleanup in time for
this transfer to occur.
Anne has faced the unsavory task of finding her own funding within the Agency,
through the Water Program, to carry on the Superfund process when her site
funding was cut back do to Regional ranking for distribution of limited resources.
Richard had another kind of struggle, a struggle with the environment itself. With
the task of revegitation at asbestos mining sites located in somewhat hostile soil and
weather conditions.
All of these problems had to be faced with creativity, coordination and finally
communication.
8

-------
Creativity plays a big part in these solutions. Although we sometimes feel as if the
constant onslaught of new and changing guidance and models has us somewhat
trapped in the Superfund mire, in the face of these challenges so common to
Superfund sites creativity make the difference. This is evidenced by the unique
solution Anne implemented by coordinating with her Region's Water Division to
find the monetary and enforcement resources necessary to keep her site moving.
Coordination can in no way be better demonstrated than by the immense task
Barbara and Katherine have faced with all of the various government bodies that
have their hands in on the base closures. This not only includes the EPA and DoD
but also all of the various political and economic agendas of the state, the counties
and the local governments, which are all vying for their own political and economic
benefits. These tasks must take into account not only the extremely important
environmental questions but also the equally compelling economic priorities of the
base dependant residents.
Finally, communication is a must. As in the situation of the revegetation of the
enormous slag piles left behind by the asbestos mines, communication can make the
difference. When there is a solution that has been implemented but does not take
hold, the only way to proceed is through communication of new ideas and resources
which may make the difference. These ideas can come from any number of sources
but only by initiating the critical communication will solutions become apparent.
This became important in the struggle to get successful revegitation of the slag piles
in an unhospitable climate. Even as the discussion proceeded, a variety of resources
and options were presented by the panel and by the RPMs participating. This is the
obvious success of tools such as NARPM itself.
Through the use of creativity, coordination, and communication even the
Superfund process with its unyielding tangle of technical and legal pitfalls can
proceed quickly and effectively.

The goals of the Remedial Investigation (RI)/Feasibility Study (FS) panel were 1) to
address issues and/or problems which confront the Superfund remedial project
manager (RPM) from both the enforcement side and the remedial/fund lead sides of
site management, 2) to present any case studies related to RI/FS issues, 3) to present
any recent policy and/or guidance which is or will be available to the RPMs for the
purpose of assisting in streamlining RI/FS's and in securing remedy selection, 4) to
identify areas where major improvements can be made in the RI/FS process, and 5)
to implement any subsequent recommendations. The resulting discussion was very
interactive between panel members and the audience.
The panel discussion began with the introductions of panel members and a brief
overview by the moderator of the suggested topics. The focus of the panel was to
discuss/suggest ways to streamline and improve the overall RI/FS process. The
topics for examination were directly related to the streamlining and improvement
process.
An overview of Expedited Site Inspections (ESIs) was presented by Steve Caldwell.
ESIs stem directly from the Superfund Accelerated Clean-Up Model (SACM) which
is being implemented to streamline the Superfund process. The concept is to have
the majority of the remedial investigation completed prior to a site being listed on
the National Priorities List (NPL). Steve expects that the RI/FS timeframe could be
shortened over a year (from four to nine quarters depending on the site) with
substantial cost savings. The key is to take a large number of sampling events in
order to characterize the site as completely as possible and to begin the RI as soon as
NPL listing is imminent. A special notice letter could go to Potentially Responsible
Parties (PRPs) prior to any hard data being collected. Features of the program would
be early actions, e.g., supplying drinking water expeditiously to areas with
contaminated ground water. The ESI should eliminate duplication of work plans,
sampling plans, health and safety plans, etc. RPMs commented that potential
problems in implementation could stem from possible delays in the NPL listing
process, resource and budget constraints, and inadequately prepared ESIs. Another
potential problem could arise with respect to PRP oversight before a site is listed. At
present, pilot ESI studies are being developed in Regions II, VIII, and IX.
10

-------
The Risk Assessment Process was addressed through a case study and subsequent
discussion. Kevin Mayer's case study was entitled Evolving Approach to
Streamlining the Risk Assessment Process at Southern California Groundwater
Contamination Sites. Kevin identified three California sites of concern. First, a full
baseline risk assessment was performed for the San Fernando site. Second, an
exposure assessment/toxicity assessment was completed for the San Gabriel site. For
the third site, San Bernardino, previous risk information for the other two sites was
used, further simplifying the process to establish remedial action objectives and
cleanup goals directly from an MCL-driven Record of Decision (ROD). Kevin
showed that this effort effectively streamlined the RI/FS activities for these three
very large sites. Overall, groundwater decisions were not made strictly on risk
assessment information but were developed from varying degrees of qualitative
versus quantitative information. The focus was to simplify the process and use the
most reliable data in conjunction with a brief risk discussion.
Subsequent to Kevin's presentation, the discussion was directed to other risk-related
issues. One RPM identified a Florida site with alternate concentration limits and
dioxin in groundwater problems. The risk assessment was held up due to problems
of state concurrence, development of surface water standards for deeper aquifers,
potential implications for other related sites, and the technical impracticability of
complete groundwater restoration. As a result of technical impracticability was, in
fact, the driving force for the site remedy, not the risk assessment. Other RPMs
made suggestions to reevaluate the ROD and to include states in the risk assessment
and ecological assessment process. Another RPM identified an issue regarding
proposed state soil cleanup standards (New Jersey). This subject prompted serious
discussion, especially as related to other media and to the potential elimination of
the risk assessment as a driving force for the remedy selection, since standards
related directly to toxicity and mobility will be actually promulgated for certain
contaminants. EPA-HQ indicated that a national guidance for action
levels/cleanup levels for soils directly related to groundwater pathways was being
developed and should be available within a few months. Guidance on sediment
cleanup levels is also being considered.
Presumptive remedy was discussed by Tish O'Conor and related RI/FS planning
and remedy selection, as identified in the 30-Day Study. The main thrust of
presumptive remedy is to develop boilerplate language for workplans through
RODs for comparative sites, e.g., wood-preserving sites, PCB-contaminated sites,
battery sites, etc.. At present, four candidate site types are being considered for pilot
projects. The idea is to set up cleanup goals rather than remedies, per se, with the
potential of eliminating the nine criteria for comparative sites. The need to develop
national expert teams for specific site types was stressed. The PCB site type, in
particular, was identified as appropriate to presumptive remedy format.
Presumptive remedies can be an excellent time-saver, since development of cleanup
levels can cut down on risk management decision-making and PRP negotiations,
and FSs can be eliminated. RPMs identified problems inherent in the process: 1)
when a site does not conform to the remedy, variations to it must be documented in
11

-------
a Federal Register notice which can involve a major time commitment and a
concentrated technical effort; 2) public comment could become unwieldy and is a
major consideration; and, 3) the elimination of an FS does not really save time,
since FS development is a comparatively quick process in relation to the RI
development. Experienced RPMs also indicated that most sites will not fit the
model. On the whole, RPMs are not in favor of the single remedy concept but did
offer support for 1) amending the ROD guidance to ensure remedy consistency, 2)
improving the RI/FS planning process with tighter scheduling, and 3) developing
effective technical expert teams to assess the selected comparative site types and
remedies. Tish indicated that the preliminary evaluation of the presumptive
remedy program will be presented in an upcoming News Alert.
Some discussion revolved around Model Consent Orders/Unilateral
Administrative Orders specifically geared to the enforcement of such orders in order
to maintain more realistic project schedules and to secure penalties for non-
compliance where available. The RPMs also suggested that procedures be developed
to assist in the enforcement of orders, both with respect to scheduling and penalties.
Penalties guidance for projects in Remedial Design/Remedial Action (RD/RA) is
due out soon; there was a suggestion that RPMs work with their regional attorneys
in adapting relevant aspects of this for the RI/FS enforcement.
The next section of the discussion dealt with potential improvements in the RI/FS
process.
Trish Gowland identified the new National Database Field (NDF) which is being
developed as a response to the criticisms from the General Accounting Office (GAO)
on disseminating accurate information on the Superfund program and its successes.
This HQ's supported database will be developed over the succeeding months, in
order to clarify existing and future site data with respect to the entire RI/FS process,
including RODs. Trish indicated that this is a proactive method for addressing the
GAO. The new NDF was not well received by the RPMs. Although some relief may
be available from the RPMs if contractors are able to input the data, this is not
guaranteed since the RPM will still have to oversee the contractors work and QA
the data input anyway. The RPMs recommended that HQ coordinate all potential
and existing surveys, questionnaires, reporting forms, and associated databases so
that RPMs do not have to "reinvent the wheel" with each request. The RPMs were
also concerned with how this will interact with existing CERCLIS and WASTELAN
databases, as well as the National Priorities List Notebook which is now available to
the regions. The NDF will attempt to direct more pertinent site information into a
central database.
SARA subpoenas deal with the issue of subpoenaing former plant workers, plant
managers, and others who worked at a facility in order to secure "first hand"
technical information on past operations and production activities for select
Superfund sites. Brad Bradley (Region V) indicated that, since we have this legal
option available to us, we should use the subpoena option to secure a valuable
12

-------
addition to other RI/FS information/data, potentially shortening the RI/FS process.
The panel recommended that the regional attorneys and RPMs try to use the SARA
subpoena whenever feasible.
The Cleanup Information Bulletin Board System (CLU-IN), formerly the OSWER
Bulletin Board, is designed for hazardous waste professionals, including RPMs, as
another potential source of information and answers. Features of CLU-IN include
electronic messaging, bulletin development, downloading of files, online databases,
and a conference network. The use of CLU-IN for RPM conferences can be
invaluable to secure up-to-date information on specific site questions or activities.
Currently, there is an existing enforcement conference on the network. The panel
recommended that NARPM set up an RPM conference on CLU-IN, including
appropriate logon procedures so that RPMs nationwide can use the network freely.
Dan Powell of the Technology Information Office can be contacted for more
information at (703) 308-8827.
Overview of HQ's Superfund enforcement/fund lead regional coordination was
discussed in an effort to see if those fund and enforcement forces could be further
joined in an attempt to pattern themselves after the regional set-up of a single
contact per site whether enforcement or fund. Overall, RPMs have found most
regional coordinators very helpful. A joint approach between OERR and OWPE is
recommended which would result in more consistency among regional
coordinators, both from a technical and administrative level. HQ indicated that
new initiatives for team development are being considered.
Tish O'Conor discussed Non-contiguous Site Strategy guidance. A short sheet will
be published within the month to announce this. This proposed guidance offers a
simplified method to connect separate sites which require the same remedy, such as
incineration for different sites' wastes which have the same contamination/wastes
and the same selected remedy. RPMs were supportive of this guidance and
suggested that it be coordinated with the multi-source aquifer group in order to
ensure consistency of remedy selection.
Overall, this was a well-received panel discussion. A group of major topics
confronting RPMs on RI/FS issues were addressed. The panel tried to follow the
thrust of Rich Guimond's initiatives which focus on RI/FS streamlining and the 30-
day study recommendations for accomplishing this through the use of SACM.
As to continued discussion, any further RI/FS issues will be addressed through the
NARPM council as they arise. Any important RI/FS issues will be addressed
through the monthly series of NARPM conference calls. The RI/FS panel will not
be formally continued as a workgroup. The moderator intends to keep apprised of
HQ's new initiatives and will apprise the NARPM Council, accordingly.

Topic 1 - USACE/USEPA Interface
Miguel Cintron of the USACE - Omaha discussed two new USACE programs called
Rapid Response and Immediate Response. Both response actions are time critical
removal/cleanup actions that an RPM can use to accelerate site cleanup. Rapid
Response usually takes between 30 and 60 days to initiate site activities and
Immediate Response only 72 hours. Also, Miguel discussed the changes in the IAG
process and using the USACE as the ARC'S work assignment manager. Attached is a
copy of the overheads used in Miguel's presentation.
Topic 2 - Site Completions and RD/RA Guidance
Tracy Loy, Section Chief of the Design and Construction Branch in Headquarters
discussed the importance of site completions. By the end of FY 92, 70 site
completions are expected and by the end of FY 93, an additional 130. Tracy also
discussed future guidance and included is a copy of a draft fact sheet titled Remedial
Action Report. Handouts attached explain the difference between the three closeout
reports and guidance on how to develop them.

-------
Background
Region V's relationship with DOJ over the past 2 to 3 years has declined
significantly, in part due to problems with DOJ's adherence to the October 1990
Strock Memo.
As part of a National Initiative to improve coordination between DOJ and EPA,
Division Directors (Regions V and III) attended a meeting at HQ with the
Department of Justice in the fall of 1991. A number of issues were identified,
including RD/RA Statements of Work (SOWs). Due to the significant problems
Region V has experienced with DOJ on this issue, our Division Director
volunteered to take the lead on SOW issues.
Project:
At the time, the Regional SOW Workgroup was working on updating our Regional
SOW and volunteered to take the lead on this project. First, we conducted a
National Survey to determine if other Regions were also experiencing problems
with DOJ (we had been told that our problems with DOJ were unique). The
Questionnaire focused on:
•	What were the Regions using for SOW? National
•	Model/Regional Models/Examples. Copies Rec'd
•	How specific were their SOWs and did they have problems with
enforceability.
•	Was the SOW negotiated?
•	Adherence to Stock Memo by Region and DOJ Opinions on National
Model SOW/CD
•	Suggestions for improving the process.
The second step is to do a comparison of the various Regional SOWs, including the
National Model to determine if there are any general trends. Finally, make
recommendations to our Division Director for possible solutions to the problem.
Results of Survey: Presented at Branch Chief Meeting Nov. 1991.
Use of Model SOW: The majority of the Regions (8) either have their own model or
examples SOWs that they use. In general, the SOWs tend to be site specific, at least
in terms of the performance standards. However, the degree of detail varies
somewhat among the Regions.
15

-------
Specificity of SOWs: ORC reviews all of the Regions' RODs and the majority (9) of
the SOWs. DOJ, on the other hand, only reviews 6 of the Regions' SOWs and no
RODs. The types of comments range from general to site specific, depending on the
Region (about 50-50).
Disputes and Enforceability: Most of the Regions experienced technical disputes;
however, it doesn't appear to cause much delay. The disputes are generally resolved
by the RPM and ORC attorney. Most Regions believe that a good SOW helps the
dispute process. These results are interesting given DOJ's concern with
enforceability of SOWs. The disputes seem to get resolved and many times without
the help of DOJ.
SOW Negotiations: Of the Regions using SOWs, all of them negotiate SOWs in
order to clarify an issue. The schedule is also negotiated in many cases. The remedy
is never negotiated. If negotiations breakdown and a UAO is issued, many Regions
will use the pre-CD negotiations SOW.
Process and Timeliness: All Regions tend to follow the Strock/Clay memo
procedures; however, DOJ doesn't tend to meet the agreed to deadlines. This
particularly true for review of mini-lit report and issuance of Special Notice;
lodging; and entry.
National Model SOW: The majority of the Regions do not want a National Model
SOW and they also believe that the SOW should be flexible and left to the Region's
discretion. It is fairly clear that the Regions want to have significant input on this -
issue. Many Regions have worked hard to generate model/example SOWs that
work by drawing on the experiences and expertise of their staff. If the National
Model SOW is finalized then it should be made optional. National Model CD:
Seven of the ten Regions do not believe any more detail is needed for the National
Model CD.
Suggest Areas of Improvement: Most of the suggested improvements had a
common theme - DOJ and their lack of timely reviews. The suggestions ranged from
holding them to the established review times in the Strock/Clay memo to leaving
them completely out of the process.
EPA—DOJ-HQ QAT:
All groups agreed that the main problem was differing definitions of quality and
timeliness, which leads to significant frustration. Good news is that everyone felt
these problems were fixable. Scheduled a 2 day meeting with QAT to resolve
problems.
Feedback: Original survey responses from RPMs, branch chiefs, ORC.
Interested in getting feedback from Regions for our SOW project.

-------
Topic 4 - Lessons Learned in Construction
Phil Rotstein of Region III discussed how treatability studies in his stabilization
remedy can be used to accelerate remedial action. Mark Bogina of Region VII
discussed his experience in implementing an alternative water supply. A rural
water district was formed to obtain property titles with no compensation to property
owners. It took approximately 2.5 years to get all of the easements. Anne Spencer
discussed PRP incentives to speed up cleanup such as breaks on oversight costs.
Anne stressed that headquarters was not supportive and better communication was
needed between the regions and headquarters.
Topic 5 - Conference Calls on Technology
Headquarters has recently setup a conference call for all the regions on incineration.
A recommendation is to continue that for other technologies. Headquarters cannot
participate due to manpower requirements, but NARPM would be a great forum to
begin getting RPM's talking throughout the nation on design and construction
issues.

Summary Report
Moderator: Maxwell Kimpson, Region IV
Panel:	Elizabeth Keicher, Region IX
Dion Novak, Region V
Cathy D. Gilmore (Region VI)
Fran Burns (Region III)
Brad Bradley (Region V)
Judith R. Black (Region VI)
Presenter: Cathy Gilmore (VI) - Role of Peer Review Committees
Purpose: To establish permanent Peer Review Committees that meet weekly to
review and plan. There are currently six committees: RI/FS Planning,
RI/FS Review, Risk Assessment, ROD Review, RD/RA Planning, and
RD/RA Review.
Recommendations/Conclusion: Peer Review Committees have the benefits of
quality work products, regional consistency, and
added perspective. Experienced RPMs are
selected as chairman, and the chairman may
develop expertise. This forum may be useful in
training.
Presenter: Fran Burns (V) - Performance Standards
Purpose: To discuss the incorporation of performance standards in the ROD, and
to eliminate the need for a Scope of Work (SOW).
Recommendations/Conclusions: The panel and RPMs strongly recommended
that the performance standards in RODs be the
preferred method. However, the RPM would
still have the option of writing a SOW if he
wished.
Presenter: Brad Bradley (V) - Construction Complete and Closeout
Purpose: To illustrate a success story and discuss the construction complete
process.
18

-------
Recommendations/Conclusions: The presenter showed the need to oversee the
PRP closely on an Enforcement-lead RD/RA. It
was emphasized that we must enforce our
agreements, assess stipulated penalties, and
maintain national consistency in enforcement.
Presenter: Judith Black (VI) - Use of Independent Quality Assurance Team (IQAT)
Purpose: To develop a quality assurance team to increase the efficiency and
effectiveness of the remedial process.
Recommendations/Conclusions: The Independent Quality Assurance Team
(IQAT) assisted the EPA oversight, and the team
was able to increase efficiency and effectiveness.
The IQAT could provide incentives to the PRP
contractor to improve the quality of their work.
The IQAT was financed by the PRPs.

Federal Facilities
Summary Report
Moderator: Craig Brown, Region IV
Panel:	Turpin Ballard, Region V
Kathryn Boyle, Headquarters
Paul Ingrisano, Region II
Diana Mally, Region V
Linda Meyer, Region X
Michele Poirier-McNeill, Region X
Susan Webster, Region VI
At the Federal facilities panel, six issues were presented and discussed. For each
issue, we began with a 5 - 10 minute presentation by a panel member, followed by an
informal discussion open to all in attendance. The following is a summary of
conclusions and recommendations for follow-up action that arose from this panel.
1.	Assessing Low Probability Hazard Sites - Michelle McNeil. Region 10
Conclusions:
The regions have independently developed a similar approach to screening
individual, low level hazard sites based loosely on application of PA/SI
methodology.
Region 10 and DOE have taken it a step further and have developed a detailed
methods manual which includes establishment of data quality objectives and
use of qualitative risk assessments.
Recommendations and Follow-up:
Questions remain on public participation and how to document decisions in
the Administrative Record.
Region 10 should provide copies of the manual or an abridged version of the
manual to other Regions and HQ.
2.	Strict Enforcement of LAG Schedules vs Team Building - Turpin Ballard.
Region 5
Conclusions:
Trends seems to be toward LAG parties working as a team and away from EPA
and State functioning strictly as "regulators".
22

-------
Informal agreements among IAG parties to move projects faster than
"enforceable" IAG schedules are common. Failure to meet the shorter
informal schedules would not trigger penalties.
It is important to define boundaries at initiation of team building and define
in writing, the assumptions for meeting the shorter, information schedules.
EPA regulations are seen by some as a barrier to team building.
3.	Quality Assurance Issues - Diana Mally, Region 5
Conclusions:
Region 5 has a lengthy formal process to approve non-CLP methods for
sample analysis. Region 5 requires lab-specific SOPs that must be approved by
the Region 5 QA Officer.
Other Regions appear to leave it up to the RPM to accept or reject use of non-
CLP methods on a case-by-case basis.
A member of the audience noted that a task force was established a couple of
years ago to develop standard protocols for Federal agencies.
Follow-up Action:
EPA HQ should report the status of the above referenced task force.
4.	Risk Assessment Issues at DOE Sites - Craig Brown. Region 4)
Conclusions:
DOE has routinely attempted to inject institutional controls into their
baseline risk assessments (BRAs). This is typically done by DOE assuming
that the current "controlled" land use remains in effect for some period of
time (100 - 300 years) after plant operations cease. DOE could effectively avoid
selection of action alternatives for sites contaminated by short-lived
radionuclides were EPA to allow such assumptions.
This approach has been uniformly rejected by the Regions as inconsistent
with the NCP.
DOE may be attempting a way to circumvent the Regions by developing land
use plans for the Weapons Plants which could be used as a basis for
establishing current and future land use scenarios used in the BRA.
23

-------
Follow-up Action:
Region 10 and Washington recently signed an accord with DOE - Handford
which prohibits use of institutional controls in the BRA and establishes a risk
matrix containing several land uses across three time periods (0 yrs, 30 yrs, 100
yrs). Other Regions who have not seen this should contact the Handford Site
Office for a copy.
5. Funding Long Term O & M at DOE Sites - Craig Brown, Region 4
Conclusions:
Due to cost and technical factors, institutional controls, alone or in
combination with other actions, will be selected as the response action at
many rad-contaminated sites.
Given that funds for site cleanup are appropriated to DOE year by year, there
is no assurance that the required funding to maintain institutional controls
and provide long term monitoring will be available to DOE in the future.
Can or should EPA sign a ROD which includes long term care and
maintenance of institutional controls at DOE site?
Follow-up:
HQ should research and report back to the Regions on the legal implications
of co-signing RODS which contain long term care or institutional control
provisions without guaranteed funding.

Community Relations Issues
Summary Report
Moderator: Laura Williams, Region VIII
Panel:	Dion Novak, Region V
Steve Sanders, Region VII
Hank Ellison (Region V)
Cesar Lee (Region III)
Lesley Brunker (Region III)
The Community Relations Panel was a new addition to the NARPM
conference this year and was one of the experimental hybrid panels which consisted
of presentations as well as directed panel discussion. There were three presentations
as follows:
1.	COMMUNITY RELATIONS AT THE BUTTERWORTH LANDFILL
SITE by Hank Ellison from Region V;
2.	EXTRAVAGANT BUT NECESSARY CONTROLS ON SUPERFUND
AIR STRIPPER DESIGNS by Cesar Lee from Region ID; and
3.	WHAT CAN HAPPEN IF YOUR ROD CALLS FOR ONSITE
INCINERATION AND HOW YOU CAN (TRY TO) PREVENT IT by
Lesley Brucker from Region HI.
The panel was moderated by Laura Williams (Region VIE) and included Dion
Novak (V), Steve Sanders (VII), and the case presenters above as panel members.
Issues: There were many important issues identified regarding the
implementation of community relations at Superfund sites. These include:
Site community has a negative perception of "the Government"
(technical expertise issue);
Site community has a lack of trust for "the Government" and
"Government" control of their lives;
The State, environmental groups, and/or PRP(s) often have secret
agendas and goals which conflict with each other or EPA;
Site community becomes more interested after the ROD is signed;
Community Relations causes additional work which requires time,
resources, and funding;
25

-------
Schedule delays in meeting deadlines due to a previously uninformed
or distrustful community
Dealing with the media community including deadlines, misquotes,
and inaccuracies; and
Additional RPM duties, funding, and resource requirements imposed
by large PRP community sites.
Discussion: Several general discussions involved identification of the site
community(ies). Many agreed that a site community consisted of anyone who was
interested in the site. Of primary concern to Superfund is the identification of those
who have the ability to undermine site progress, including the public community,
local officials, Congressionals, States, PRPs, environmental groups, and even
internal EPA opposition. While these are all valid communities, the focus of this
first panel's recommendations were the public community, local officials, and
environmental groups.
It was determined during discussion of the presentations that many RPMs
had been blindsided by community relations issues because earlier site work had
proceeded without mishap. The two most likely times during the Superfund
process for these surprises to occur are 1) during initiation of the Remedial Design
and 2) when a "new" RPM (new or just an experienced RPM new to the site) was
assigned to the site. Many times, these two events were coincidental. As identified
in "Issues" above, the community seems to become much more interested and,
therefore, more vocal at the post-ROD phase. It may be that this occurs because the
community has been "awakened" by the public meeting/proposed plan/media
announcements activities which are focused at the site community. If only
CERCLA requirements are implemented at a Superfund site, this would also be the
first time that the site community at large is directly contacted and informed about
the site. While the ROD may proceed to signature without significant public
comment, it has been observed that as design and construction become more real,
the community becomes much more interested in the details and day-to-day
implementation of the project.
It was brought to the panel's attention that community relations, even those
minimally required by CERCLA, require considerable effort on the part of the RPM
as well as additional resources, funding, and time to complete the Superfund
process. It was acknowledged that this appeared to be the case at the outset of a
project; however, it was the general consensus from the audience and the panel that
the benefit and potential problems solved by a proactive community relations effort
far outweighed the initial costs. In fact, almost all issues identified above could be
minimized and sometimes reversed to EPA's favor.
26

-------
The remainder of the discussions were related to the presentations and how
negative public sentiment had been changed to some type of informed consent. The
methods used to effect these changes included identification of specific community
concerns, development of an interactive community relations effort, and continued
proactive community relations. The primary tool used in these efforts was the
public availability session which often included a focused, well developed
presentation. Central to these sessions was the availability of the RPM as well as
risk assessment personnel, EPA management, and others who could answer the
majority of questions asked by the attending community. Once the community's
concerns had been addressed, availability sessions were conducted with a smaller
number of EPA personnel. A somewhat related concern was that RPMs/EPA does
not get the credit for having made the proactive effort. Instead, Congressionals or
environmental groups are often made to look good for "having made EPA be more
cooperative." Again, the benefits to EPA outweigh this slight (though internal
awards/rewards "for doing the right thing right" could be developed).
Community Relations is one of the few ongoing activities during the entire
Superfund process. "It is the single most important thing we do!"
Recommendations: The following recommendations were discussed during
the panel and presented to the NARPM conference attendees.
1.	Superfund must take a proactive approach to community relations.
Anticipate and respond to the community's wants and needs - don't
wait for it to explode. This means that EPA cannot wait until the
proposed plan phase but must inform and involve the community
early in the RI/FS process and continue through RA and deletion.
2.	At your meetings with the public, bring appropriate staff to answer the
community's questions. EPA credibility is decreased when we "don't
know," or have to correct ourselves later.
3.	Mandatory training for RPMs in Community Relations and informed
consent skills and techniques, not just Community Relations
requirements in CERCLA.
4.	Provide an open forum for communication between EPA and the
community which is non-threatening and provides technical
information in terms which are easy to understand. One
recommendation is the use of multiple availability sessions instead of
the formal and required "public meeting." The physical requirements
of public meetings leads to an us-them type of seating and thinking.
5.	As mentioned above, recognition and/or awards "for doing the right
thing right." This would be hard to implement but would be extremely
satisfying to have RPMs rewarded for preventing a crisis.
27

-------
6. And last, but not least - keep this panel for the 1993 NARPM
Conference! It provides a forum for an exchange of ideas, experience,
and skills for one of the most critical components of getting sites clean.
Resources Needed to Implement Recommendations:
1.	Primarily funding, for: training of RPMs (would be included as part of
80-hour requirement); additional dollars to conduct proactive
community relations from early in the RI/FS to deletion of the site;
funding for additional resource requirements to provide appropriate
staff at availability sessions, meetings, etc.; and awards/rewards.
2.	Resources, for: development and implementation of awards; and
resource requirements to provide appropriate staff at availability
sessions, meetings, etc.

Expedited RD/RA
Summary Report
Moderator: Janet Cappelli, Region II
Panel:	Bruce Sypniewski, Region V
Bill Bolen, Region V
Neilima Senjalia, Headquarters
Erna P. Acheson (Region VIII)
Douglas A. Bell (Region IV)
Jeff Gore (Region V)
Karen Vendl (Region V)
Panel 6 was divided into two sessions. The first part of the panel discussion was
devoted to various case studies. The case studies focused on different methods that
were used to either expedite the RD/RA process or expedite the Superfund process
to get to RD/RA.
Karen Vendl, Region V, discussed her success with using removal authorities to
expedite a remedial action. She discussed how she used the authority explained in
OSWER Directive # 9355.0-25A to get local residents onto a municipal water supply.
Doug Bell, Region IV, talked about his experiences with a "mega-site" and how he
used interim action RODs to excelerate the Superfund process so that the RD/RA
could begin. Erna Acheson, Region VIE, shared her know-how on effective
management of contractors and establishing a rapport with PRPs to do quick
remedial actions at a radium site in Denver. Jeff Gore, Region V, discussed the
various mechanisms that were used to streamline the RD/RA process at a
Superfund site. Combining the construction bidding process with the RD/RA
workplan submittal and approval process and meeting regularly with the PRPs,
were mentioned.
The second half of the panel discussion was a presentation by Gary Worthman from
the Office of Waste Programs Enforcement in Headquarters. Gary talked about a
memorandum which would implement a recommendation of the 30-day study
concerning accelerating RD starts. At the time of the NARPM conference, Gary was
in the process of writing this memo. He committed to releasing the memo to
Regional NARPM representatives so that it could be distributed quicker vs. the
traditional trickle down method (Division Directors, Assistant Division Directors,
etc.). April 2, 1992 OSWER Directive # 9835.4-2b was released to the Regional
NARPM representatives as a result of this request. Regional NARPM
representatives should let other RPMs know of the availability of this memo.

National Meeting
of
Remedial Project Managers
March 17-20,1992
Atlanta, Georgia
PROGRAM AGENDA AND ABSTRACTS
Inarpm 5?
I National Association of Remedial Project Managers J
Sponsored by the National Association of RPMs (NARPM)

-------
Welcome!
Welcome to the Third Annual National Meeting of Remedial Project Managers
(RPMs). This meeting has been organized by the National Association of RPMs,
fondly referred to as NARPM.
This year's meeting culminates nearly a year of incredible growth for NARPM as
an organization. Significant RPM participation during and following last year's
meeting has helped us move closer to achieving the goals established when
NARPM was first organized: to develop a national vehicle for the exchange of
professional expertise and work experience among RPMs; establish permanent
panels and workgroups to explore and resolve, if necessary, recurring site
remediation issues; provide a single cohesive voice to communicate and work
with Headquarters on policy and guidance issues; and provide opportunities for
RPMs' professional growth in the areas of technology and management. With
increased support from Regional management, RPMs and Headquarters, alike,
NARPM has also achieved some important new goals this past year.
Increased visibility and credibility of NARPM in Headquarters: The National
Co-Chairs met last fall with Richard Guimond, Deputy Assistant Administrator
of OSWER, to discuss NARPM's role as a representative both of RPMs' needs and
of RPMs as a valuable resource. Mr. Guimond, in turn, voiced his support of
NARPM and its goals in a recent memo addressed to both Headquarters and
Regional management. He has further demonstrated his support with his "open
door" policy to allow-RPMs to communicate problems, suggestions and issues
directly to his office through the NARPM Co-Chairs.
Improved communication among RPMs through a national newsletter The
first issue of the NARPM National Newsletter, distributed late in 1991, has
received rave reviews from Headquarters, Regional management and staff, as
well as from our peers in the National On-Scene Coordinators Association
(NOSCA). In order to include conference highlights, the second issue of the
newsletter will be distributed shortly after this conference.
Interact directly with Headquarters on issues of importance to RPMs: Mr.
Guimond will include several RPMs on his Super fund Excellence Team, which
will assist in implementing the goals of the 30-Day Study. Also, we once again
welcome qualified and interested participants from Headquarters to our panels
at this year's meeting. These representatives have been invited to participate
based on their close involvement with Headquarters' work on the particular topic
of discussion. Finally, both Mr. Guimond and Headquarters have expressed
support for integration of the recommendations of these panels and, potentially,
panel members, as well, into new and existing Headquarters workgroups on
these topics.

-------
In developing this meeting, we have emphasized the new direction the
Superfund program is taking. We have maintained the five standing panels from
previous years, as well as the well-received block of site-specific case studies.
The focus of the panels and the majority of the case studies will be streamlining
the Superfund process: identifying areas where streamlining efforts have been
successful, and where we have both a need and an opportunity for improvement.
This year we are also sponsoring several new panels on a trial basis. Each of
these new panels is based on several case studies concerning a similar site type or
issue. The intent of these trial panels is to focus the discussion to address a
specific problem or issue raised by the case study(ies). If we effectively address
the issue(s), RPMs with this or a similar concern will be able to take back to the
Region an immediate suggestion or answer to apply directly to his/her site,
ultimately shortening the time required to resolve the particular issue.
The national council will be preparing a summary of the conference for
distribution to the Regions and Headquarters to demonstrate the progress made
at this meeting. The summary will include not only a synopsis of papers
presented, but also issues identified, potential solutions proposed, and solutions
successfully implemented to date. Through your active and candid participation
in this conference, it will be possible to convey RPMs' highest priorities for
Superfund directly to Headquarters.
This year we are very pleased to welcome Richard Guimond as our keynote
speaker. Without his support and willingness to maintain an "open door" with
RPMs through NARPM, this year's conference would hardly have been possible,
special thanks to Mr. Guimond for his continued support of NARPM.
Thanks to all the regional representatives and to everyone who helped to plan
the meeting. Special thanks also to all of you for your valuable contributions that
will once again make this national meeting a success!
Sincerely,
Raruty Dominy

QUICK REMEDIAL ACTION OF A DENVER RADIUM SUPERFUND SITE
Erna P. Acheson
(303) 294-1971
FTS 330-1971
ABSTRACT
The Denver Radium Superfund Site consists of 16 separate properties which
were contaminated between 1914 and 1927 with radium processing wastes. An
International House of Pancakes (IHOP) restaurant is one of the radium
contaminated properties. This property is located along a major transportation
corridor on the east side of downtown Denver. The restaurant was closed for six
weeks to facilitate the removal of radium-contaminated materials beneath the
restaurant and the parking lot adjacent to the restaurant.
Radium contamination at the property resulted from manufacturing of
thousands of luminous dials for military use (1919-1920) by the Cold Light
Manufacturing Company. In 1924 the property was converted into an apartment
complex and remained that way until 1939. Between 1939 and 1962 the original
structure was razed and the property was used as a car sales lot. In 1965, IHOP
built a restaurant on the property which remains in operation today.
The primary challenge in remediating this property was removing 89 tons of
contamination from the IHOP interior and 670 tons of contamination from the
parking lot located directly east of IHOP. In order to minimize the amount of
time that IHOP would need to be closed, EPA directed its contractor to work 3
shiftts 24 hours a day, for the first two weeks of the Remedial Action (RA).
Buried contamination was found to continue beyond assessed boundaries both
inside IHOP and in the parking lot. The additional contamination required that
the initial estimate of four weeks for RA be extended an additional two weeks.
Once cleanup was complete, the restaurant was restored and the parking lot was
reconstructed. The property owner reopened IHOP 20 hours after completion of
the final, post-construction review of cleanup activities and reconstruction.
Because IHOP is located along a major transportation corridor and is the most
visible of all the Denver Radium sites, the assumption was that additional
community relations involvement would be necessary during the RA. However,
the property owner worked with the EPA and their contractors to minimize the
visibility of the RA such that there was minimal public interest about the ongoing
RA.
A total of 759 tons of radium-contaminated material was shipped to Utah for
disposal during the first four weeks of the RA. The quick RA was successful in
releasing the property for unrestricted use.

SUCCESSFUL REMEDIATION OF MANY UNRELATED PROPERTIES:
OPERABLE UNIT VI OF THE DENVER RADIUM SUPERFUND SITE
Erna P. Acheson
(303) 294-1971
FTS 330-1971
ABSTRACT
Operable Unit VI (OU VI) of the Denver Radium Site consists of ten separate
properties which were contaminated between 1914 and 1927 with radium-
processing wastes. These properties are at various locations throughout the Denver
Metropolitan area. Because of the limited contamination thought to exist on these
properties, they were grouped together under one OU. Portions of the
contamination on three of the properties is believed to have been the result of a
1920's radium-processing laboratory and the rest of the contamination on the other
properties is believed to be the result of processing wastes transported from the
various processing sites around the city.
Cleanup was conducted in three phases with a final phase for the last property
scheduled for the summer of 1992. A total of 1,260 tons of contamination was
estimated in the OU VI Remedial Investigation. This estimate was increased to 2,324
tons during the Remedial Design. A total of 4,083 tons of contamination has been
removed from nine properties during the first three phases of Remedial Action (RA).
The radium contamination was shipped by both dedicated bi-modal truck mounted
containers and by railroad gondola cars to Utah for disposal.
RA workers performed the majority of the cleanup work in "Level D" protection.
This level of protection was possible due to thoroughly wetting the excavation such
that concentrations of hazardous substances in the air were well below the
permissible exposure limit. Radium-contaminated soils were excavated in six-inch
lifts in order to minimize the amount of "clean material" that is removed with the
waste. The determination as to what material exceeds the cleanup criteria is made
by field personnel measuring gamma-exposure rates using hand held
scintillometers.
Between October 1990 and September 1991, radium contamination was removed
from seven OU VI properties. One property was found not to be contaminated;
however, one additional property located adjacent to one OU VI property was found
to be contaminated. This additional property is assessed to have approximately 600
tons of contamination and is scheduled to be remediated during 1992.
Contamination buried beneath a water line located on one of the properties was left
in place. With the exception of the property with the water line, the remaining
properties which have been remediated have been released for unrestricted use.

DETERMINATION OF PCB CLEANUP LEVELS IN WETLANDS
SEDIMENT, KIN-BUC LANDFILL SUPPERFUND SITE, EDISION, NEW
JERSEY
Alison Barry
EPA Region II
FTS 264-8678
ABSTRACT
At the Kin-Buc Superfund Site in Edison, NJ, ecological risks associated with
PCB-contaminated wetlands provide the basis for determining PCB cleanup
levels for wetlands sediments. A former industrial landfill located on the banks
of the Raritan River, the site includes approximately 80 acres of tidal wetlands.
The Operable Unit 1 ROD selected a containment remedy for the landfill
mounds, and called for a second operable unit remedial investigation to
characterize contamination in the wetlands and remaining areas of the site. The
second RI identified pervasive PCB contamination in sediments found in the
Edmonds Creek/Marsh tidal system-widespread contamination at levels less
than 10 ppm, with "hot spots" up to 730 ppm in the area closest to the landfill.
Biota sampling conducted on fish, fiddler crabs, and muskrats within the study
area indicated bioaccumulation of PCBs in both fish and fiddler crabs.
Based on the RI, the remediation of the wetlands will be driven by the
relationship between PCB concentrations in the sediment and the PCB body
burdens observed in aquatic species at the site. The Human Health Assessment
did not identify any unacceptable risks associated with direct contact with the
sediments. However, unacceptable non carcinogenic and carcinogenic risks are
associated with ingestion of fish caught on or adjacent to the site. The Ecological
Assessment concluded that PCBs presented a major risk to aquatic life through
successive bioaccumulation of PCBs observed in aquatic food chains.
Additionally, terrestrial and avian species that feed on aquatic organisms may be
at risk, based on estimated dosages of PCBs. Such species include the great blue
heron, a NJ endangered species observed at and adjacent to the site.
EPA determined cleanup levels for PCBs in wetlands sediments by evaluating
several approaches. The Interim Equilibrium Partitioning (EP) method (Office of
Water, 1988) was used to evaluate the bioavailability of PCBs in sediment. PCB
data, normalized to Total Organic Carbon (TOC) for each Sediment Quality
Criteria (SQCs) calculated for each point at the mean and 95% confidence
intervals (upper and lower). Given the technical limitations of this approach, this
method may help identify those areas which correspond to the greatest
ecological risk. EPA also considered the NOAA ER-L (.050 ppm) and ER-M (.400
ppm) values reported by Long and Morgan (1990), which may be used as
guidance values for evaluating biological effects. These technical approaches
were considered against remediation goals established for PCBs in sediments at

-------
other Superfund sites, and against competing factors such as the technical
feasibility of full remediation and restoration and the desire to minimize further
degradation of the wetlands through invasive remediation techniques. After
consideration of these issues, EPA concluded that a preliminary remediation goal
of 5 ppm, which provides for "hot spot" removal, represents an appropriate level
of protection for the Edmonds Creek/Marsh system.

CASE STUDY: THE WRIGLEY CHARCOAL SUPERFUND SITE, WRIGLEY,
HICKMAN COUNTY, TENNESSEE
Douglas A. Bell, P.G.
U.S. EPA, Region IV
(FTS) 257-7791
ABSTRACT
The 3000-acre Wrigley Charcoal CERCLA Site (HRS of 36.14) is located 45 miles
southwest of Nashville, Tennessee and is situated in and around the town of
Wrigley, Tennessee. The Site, which was placed on the NPL on March 31,1989,
consists of four distinct areas of contamination: 1) the 35-acre Primary Site where
pig iron and wood retorting operations took place from 1881 to 1966,2) the 3 acre
Storage Basin used for waste water storage and disposal in the 1950's, 3) the 3.5
acre Athletic Field built over a ravine filled in with blast furnace slag and
contaminated soils in the 1940's, and 4) the 40-acre Irrigation Field used for waste
water disposal. Additional operations were conducted from 1978 to 1983, mainly
in several of the remaining on-site buildings. Operations during this 5-year
period consisted of metals machining, storage of drummed waste products
obtained from other local industries, and recovery of copper from transformers.
The Wrigley Charcoal Site is now abandoned, but manufacturing and disposal
activities left significant contamination at the Primary Site and the Storage Basin.
Primary Site soils were found to be contaminated with phenols, 2, 4-
dimethylphenol, benzene, toluene, polycyclic aromatic hydrocarbons (PAHs),
halocarbons, asbestos, traces of furans/dioxins, a variety of metals, and broken
ACM from roofing materials. The Storage Basin contains raw coal-tar sludges
and soils which contain very high levels of phenols and PAHs, and high levels of
VOCs and metals. Overall analyses at the Athletic Field revealed relatively low
levels of lead, copper, zinc, PAHs, toluene, xylene, and dibenzofuran. Analyses
at the Irrigation Field revealed slightly elevated levels of metals in a relic
wastewater holding pond.
Concerns at the Wrigley Site consist of: 1) dermal contact/ingestion or
disturbance of exposed coal-tar wastes, metallic wastes, and ACM, 2) the
potential release of tar-like materials from two large tar-pits into an adjacent
creek is also of concern, however, emergency actions taken in 1988 have
temporarily reduced the threat of tar-pit failure, 3) the potential release of these
wastes and associated volatile contaminants and metals particles into the air, 4)
disturbance or mobilization of coal-tar sludges at the Storage Basin, and 5)
potential contamination of other Site related areas such as the Athletic Field and
Irrigation Field that received transported site wastes.
The cleanup of the Wrigley Charcoal site can be accomplished in 3 operable units.
Implementation of an Interim remedial action for the first operable unit will

-------
expedite and streamline remedial activities by addressing the most imminent and
substantial threats while permanent solutions are developed for the entire Site.
Interim activities include removal and disposal of exposed coal-tar wastes and
adjacent soils, removal and disposal of ACM; temporary consolidation and
storage of materials such as tar-cubes and contaminated metallic materials that
will be eliminated in subsequent remedial actions; and reconstruction of the
spillway area that was damaged during Spring 1991 flooding. Operable Unit 2 is
proposed to address remediation of the tar-pits, soils, and Storage Basin sludges
contaminated primarily with PAHs, phenols, VOCs, and metals. Preliminary
estimates of these materials range from 100,000 cy to 240,000 cy. Operable Unit 3
is proposed to remediate any groundwater problems. Subsequent groundwater
studies will be required to definitively identify extent of groundwater
contamination. Presently, low to moderate contaminant levels have been
identified in on-site groundwaters.

USE OF INDEPENDENT QUALITY ASSURANCE TEAM (IQAT) DURING
REMEDIAL ACTIVITIES AT FRENCH LIMITED SUPERFUND SITE
Judith R. Black
U.S. EPA - Region VI
ABSTRACT
The French Limited Site is an abandoned industrial waste management facility
located in Harris County, Texas near Houston. The 22 acre site contains a 7.3
acre lagoon into which waste materials were placed, and surrounding sloughs
which in the past received spills and overflows of contaminants from the lagoon.
The EPA entered into a consent decree with 90 PRPs whereby they must conduct
an insitu bioremediation remedy for the lagoon and pump and treat for ground
water. The French ROD marked the first pump and treat for ground water. The
French ROD marked the first application of bioremediation at a Superfund site in
the Nation.
In the Fall of 1987, during the insitu pilot program, the French Limited Task
group began assembling a team of qualified experts to aid in planning,
management, control, and documentation of remedial activities. This team
included representatives from various disciplines such as hydrogeology, biology,
air monitoring, risk assessment, engineering, construction, and health and safety.
The so-called Independent Quality Assurance Team (IQAT) has remained
dynamic through the various project phases to insure that the team remained
"independent" of the remedial contractor as well as meeting new project needs.
The IQAT prepares a monthly report that is sent in final form to the PRP Project
Coordinator and the EPA RPM.
The IQAT team and the reporting procedures were formalized as recommended
in the EPA Document, "Guidance on EPA Oversight of Remedial Designs and
Remedial Actions Performed by Potentially Responsible Parties", Interim Final,
dated April, 1990.
The IQAT has been very thorough in testing, inspections, reviews, and providing
recommendations for areas of improvement in approved workplans, designs,
and field applications. Use of the IQAT has very much helped to provide a high
level of confidence to the EPA and the PRPs that: 1) remedial activities are
conforming to properly developed requirements; 2) costs and time saving
measures are utilized; and 3) that the project continues to benefit from
improvement over the life of the project.

REMEDIAL CONSTRUCTION COMPLETION AND CLOSEOUT AT THE
JOHNS-MANVILLE SITE IN WAUKEGAN, ILLINOIS
Brad Bradley
Region V
(312) 886-4742
FTS 886-4742
ABSTRACT
The Johns-Manville Site is an approximately 120-acre above-ground landfill
containing the off-specification products and wastes from the Johns-Manville
asbestos manufacturing processes in Waukegon, Illinois. The remedial action at
the site, primarily consisting of soil covered with vegetation, was successfully
completed in August 21,1991, and the site close-out report was signed on
December 31,1991.
The audience will gain an understanding of the various legal and technical steps
involved in the process of completing remedial construction at this site, including
shutting down work and discovering and implementing work at additional areas
of the site that were not specifically addressed in the ROD. A brief overview of
the close-out process will also be presented.

WHAT CAN HAPPEN IF YOUR ROD CALLS FOR ONSITE INCINERATION
AND HOW YOU CAN (TRY TO) PREVENT IT
Lesley Brunker
EPA Region IE
(FTS) 597-0985
ABSTRACT
Onsite thermal treatment is a well-established, viable alternative for cleanup of
many types of wastes found at Superfund sites. However, public perception of
this technology is not always favorable; influential national and international
environmental organizations such as Greenpeace are publicly opposed to the use
of incinerators. Due in part to the increasingly negative perception of this
treatment technology and in part to rapidly changing demographics, and
community formerly supportive of a Region HI Record of Decision has become
angrily opposed to EPA's cleanup plans. In response to concerns raised by the
local community and to requests made by a high ranking U.S. Senator, Region EI
has prepared a series of presentations that have been given at public meetings for
two sites. The presenters include the Remedial Project Manager, who explains
why this technology has been proposed or selected for this site; a high-ranking
regional manager, who assures the public that the incinerator will be operated in
a safe manner; and industry expert, who gives a detailed technology overview;
and a toxicologist, who addresses the risk posed by the site and by the proposed
or planned cleanup method. This presentation has been well-received by local
residents and elected officials.

PERFORMANCE STANDARDS
Fran Burns
EPA Region HI
FTS 597-4750
ABSTRACT
This presentation discusses the use of performance standards for the selected
remedy in the Record of Decision, which eliminates the need for a separate
Statement of Work as an appendix to the Consent Decree. The recent experience
of Region HI in writing performance standards in the Records of Decision will be
discussed.
Performance standards are the criteria and conditions that have necessitated the
remedy and the standards that define what the selected remedy must
accomplish. The Department of Justice has experienced difficulty in defending
or negotiating some of the older Records of Decision because the "Selected
Remedy" section of the ROD was written in an ambiguous manner, or omitted
criteria that EOA considers a benchmark for a successful remedy. DOJ requested
that a Statement of Work be attached to the Consent Decree to correct the
omissions of the RODs, but Region 3 believed that the ROD should contain the
Statement of Work for the Consent Decree. The Consent Decree could then refer
to the ROD, which is preferred because the ROD is a final, signed Agency
document and is not open to negotiation with the PRPs.
This presentation includes a description of the Department of Justice's need for
performance standards in the ROD, the evolution of performance standards, and
the recommended format for the performance standards.

RI/FS STREAMLINING
(Groundwater Investigations)
Dennis G. Dalga
Region V
(312) 886-5116
ABSTRACT
A large amount of time and resources are generally spent on Superfund sites
in performing investigations of the hydrogeological characteristics of the site.
Very often, however, varying amounts of time and resources could have
been saved if only the subsurface conditions could have been better
anticipated. Since this is not always possible, other mechanisms are needed to
speed the process and hopefully save money at the same time. My
presentation deals with the activities which were undertaken at the Conrail
Superfund Site (Elkhart, IN), which has a large study area with extensive
groundwater contamination. I will discuss the preliminary investigations
which were performed, based on what was thought to be the subsurface
conditions at the site. I will also discuss how, even though some questions
were answered, and some situations verified, other questions/concerns came
out of the initial investigation.
Finally, and most importantly, I will discuss the investigative approach
which we employed for subsequent phases, which allowed us to more
efficiently study such a large area, in a relatively short time frame, at a cost
much less than placing numerous monitoring wells through a number of
phases of investigations. Specifically, I will discuss our use of a lead-screen
auger, which allowed us to take groundwater samples at whatever depths
were deemed appropriate during a single drilling effort, and after analyzing
these samples in the field lab, allowed us the flexibility to sample at whatever
additional locations were desired, based on the results of previous sampling
efforts, groundwater flows, etc.

LESSONS LEARNED: A COMPREHENSIVE ECOLOGICAL RISK
ASSESSMENT
MILLTOWN RESERVOIR SEDIMENTS SUPERFUND SITE
Julie A. DalSoglio, RPM
Janet Burris, Toxics Integration Branch
ABSTRACT
EPA initiated a comprehensive and innovative ecological risk assessment at the
Milltown Reservoir Sediments Superfund Site in August 1989. Three years later
EPA will release a draft baseline risk assessment for public and PRP review. This
case study presentation will present a review of the process implemented in
conducting a large scale ecological analysis, information gained about
appropriate use of methodologies, resources available to RPMs and projects,
pitfalls to avoid, and recommendations for streamlining the process.
The Milltown Reservoir Sediments Superfund Site is located in Western
Montana, approximately 120 river miles downstream from the historic mining
district of Butte and Anaconda, Montana. This site is one of five contiguous
Superfund Sites located in the Clark Fork River basin and consists of 80 river
miles between Warm Springs Ponds and Milltown and an 820 acre wetlands
habitat located behind the Milltown Dam at the confluence of the Clark Fork and
Blackfoot Rivers. Early investigations at the site showed no evidence of acute
toxicity to the wetlands environment; however, several episodes of large fish kills
have occurred below the Warm Springs Ponds and Milltown Dam. The Montana
Department of Fish, Wildlife & Parks has also asserted that relatively low fish
populations in the river system were a consequence of poor water quality and
habitat in the Clark Fork.
EPA decided to conduct a baseline ecological risk assessment in the reservoir
area and a screening assessment in the river. The focus of the study has been to
identify any chronic, sublethal impacts from contaminated sediments in these
environments. A 46 member advisory committee was established with
representatives from State and Local agencies, public interest groups, local
citizens, and the PRP. Four work groups (public health, wetlands, fisheries, and
continued releases) were formed to provide technical assistance and PRP and
public input in work plan development. Lack of an established sediment quality
criteria, limited EPA field and laboratory protocols, and minimal guidance for
ecological assessments provided a major challenge for work plan development.
The project ended up consisting of a preliminary field season and a second year
baseline field and laboratory assessment with a draft baseline risk assessment
planned for September 1992.

COMMUNITY RELATIONS AT THE BUTTERWORTH LANDFILL SITE
Hank Ellison
HSRW—6J
Region V
(312) 353-6577
ABSTRACT
The Butterworth Landfill is a former municipal landfill operated by the City
of Grand Rapids, Michigan, from early in the 1950s until 1973. The landfill
received both residential and industrial wastes. The site is approximately 180
acres in size and is located predominantly within the 100-year floodplain of
the Grand River. The area around the Butterworth site is predominantly
industrial; however, there are also ethnic neighborhoods, a ball park and zoo
in close proximity to the site.
This is a PRP-lead Remedial Investigation /Feasibility Study, with U.S. EPA as
the lead oversight agency. Other groups which have been active at this site
include a local environmental group, the contractors for the first Technical
Assistance Grant (TAG) awarded in the State of Michigan, the Michigan
Department of Public Health and the Michigan Department of Natural
Resources.
Community relations problems that have surfaced at the site include a
general distrust by the residents of government officials, a historical conflict
between residents of the neighborhoods surrounding the site and the city,
strained relations between the city and the state, and hidden agendas on the
part of both the local environmental group and the TAG contractor.
Development and implementation of a very active community relations plan
has minimized or alleviated these issues and helped build a more trusting
relationship between the community and EPA.

TO LEACH, OR NOT TO LEACH: SOIL CLEANUP LEVELS THAT
PROTECT GROUND WATER
Mark J. Fite
EPA Region VI
FTS 255-6715
ABSTRACT
Establishing soil cleanup levels based on risk has become more of an exact
science in recent years with the publication of standard risk assumptions in the
new Risk Assessment Guidance. However, risk-based cleanup levels may not
protect the ground water from infiltration-induced leaching from contaminated
soils. Soil cleanup levels which are both protective of the ground water yet cost
effective (not overly conservative) are, to say the least, difficult to derive. Project
managers generally rely on leaching tests such as the TCLP and computer
models such as V-Leach and the Organic Leaching Model (OLM) to establish
these cleanup criteria.
In practice, running TCLP extractions on all confirmation samples during a
Remedial Action to verify compliance with the no leaching standard could prove
cumbersome and costly. On the other hand, relying strictly on a model-derived
action level without some validation using actual leaching data could lead to
questions about the remedy's effectiveness. As an alternative, both tools can be
used to minimize construction costs and increase EPA's confidence in the
cleanup standard.
The South Cavalcade Street Site in Houston, Texas, is a former wood treating
facility contaminated with polynudear aromatic hydrocarbons (PAHs).
Currently, the PRPs are collecting an extensive amount of soil data in order to
define the areas requiring remediation. Those soils which exceed the risk-based
soil cleanup level are marked for remediation, while a TCLP extraction and
analysis is done on those soil samples which fall below the risk-based level to
evaluate leaching potential.
Based on the database of samples used to develop the Organic Leaching Model
(OLM), EPA has determined that approximately 85 pairs of data comprising
PAH analyses and the corresponding TCLP results will serve to validate the
OLM results for the site with 95% confidence. In order to validate the model, the
actual carcinogenic PAH concentrations of those soils which leached using the
TCLP test will be compared to the OLM derived action level to verify that no
leaching occurred in soils with concentrations below the action level established
by the OLM.

-------
If the OLM-derived cleanup levels prove to be valid, these cleanup levels will be
used to evaluate the leaching potential of soils in lieu of TCLP extraction and
analysis during the Remedial Action.

ROLE OF PEER REVIEW COMMITTEES
Cathy D. Gilmore, RPM
U.S. EPA - Region VI
ABSTRACT
Background: About three to four years ago, in Region 6, the Peer Review
Committee process for Superfund was born. The first committee was organized
due to a concern over the inconsistency between Records of Decision (ROD), the
lack of sharing of lessons learned between sites, and, with the RPM revolving
door at that time, the concern over the need for sharing expertise and knowledge
gained by more experienced RPMs. The goal of the committees at their inception
was to take advantage of the cumulative experience of the program.
Current Status: From the start of the Peer Review concept in Region 6, with the
formation of one Peer Review Committee, the Region 6 Superfund program
now has six functioning committees. These committees are the RI/FS Planning
Committee, the RI/FS Review Committee, the Risk and Ecological Assessment
Committee, the ROD Committee, the RD/RA Planning Committee, and the
RD/RA Review Committee. These committees are made up of RPMs and other
skill groups from the Superfund or related programs. Each committee has a
membership of 5 to 8 people, and review and comment upon almost all
documents submitted for review.
Conclusion: The Peer Review Committee process, as it is known in Region 6, is
a viable, useful process. It fulfills several program needs that vary from
providing consistency and better work products to training of new staff. As the
Superfund program evolves in Region 6, so will the Peer Review Committees.
Future issues to be considered by these or new committees include deletions, 5-
year review, operation and maintenance, and possibly Superfund contracting
needs. The Peer Review Committees are one aspect of a Total Quality
Management approach for the Superfund program in Region 6.

STREAMLINING THE RD/RA PROCESS AT THE
SEYMOUR SUPERFUND SITE
Jeff Gore
Region V
312-886-6552
ABSTRACT
The purpose of this paper is to outline an actual example of how the remedial
design/remedial action process was creatively carried out at the Seymour, In.
Superfund Site in order to complete construction activities over two years ahead of
a mandated schedule, while meeting all of the regulatory and design requirements
of the Consent Decree.
The remedial design/remedial action activities at the Seymour Superfund Site were
performed in a responsible party lead status. The Consent Decree and Remedial
Action Plan for the Site required the Settling Parties to implement eight aspects of
extensive groundwater, soil, and community remedial action activities within a
five-year period. In addition, over 20 document submittals were required to be
drafted, reviewed and approved before the related remedial action components
could be constructed and completed.
Both U.S. EPA and the Settling Parties agreed that expediting the RD/RA process
would be beneficial because the migrating groundwater plume could be more
quickly contained, public health risks could be more quickly eliminated and RD/RA
costs could be minimized.
In order to expedite the RD/RA process, document submittal, review, and approvals
needed to be streamlined. This was done by combining the construction contracting
bidding process with the agency work plan and health and safety plan submittal and
approval process. Review of document submittals was performed only by a small
team which was actively involved with the project, and which was very familiar
with the ongoing RD/RA activities.
The result is that all required remedial action construction activities are scheduled
to be completed in 1991, over two years ahead of the schedule outlined in the
remedial action plan; all the conditions of the Consent Decree are being met; the
migrating groundwater plume is being contained and treated more effectively; and
public health risks have been eliminated or reduced more quickly.
This paper was presented as part of a group session at the Hazardous Materials
Control '91 Conference in December and includes a number of slides in the
presentation.

THE APPLICATION OF INNOVATIVE TREATMENT TECHNOLOGIES IN
REGION VI
Deborah D. Griswold
U.S. EPA - Region VI
ABSTRACT
Background:
In 1986 the signing of the Superfund Amendments and Reauthorization Act
(SARA) placed a new emphasis on the selection of treatment technologies for
the remediation of hazardous waste sites. Section 121 (b) (1) 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." As there were few
demonstrated treatment technologies available, innovative treatment
technologies became prominent options. SARA also states an alternative
remedial action can be selected, even if such an action has not been achieved
in practice at another facility or similar site (SARA 121 (b)(2). The 1990
National Contingency Plan (NCP) went further to state that "innovative
treatment technologies will be considered if those technologies offer the
potential for comparable or superior performance or implementability; fewer
or lesser adverse impacts than other available approaches; or lower costs for
similar levels of performance than demonstrated treatment technologies."
(NCP 300.430(e)(5))
The end result of the preference for treatment technologies has been the
increased selection of undemonstrated and innovative treatment
technologies for the remediation of Superfund sites.
Analysis:
A survey will be used in order to gather the necessary information for
evaluating innovative treatment technologies in Region 6. Region 6 RPMs
will be questioned on their problems relating to the application of innovative
technologies. RPMs with site problems warranting further examination will
be interviewed in person for their experiences.
Findings:
Certain risks are inherent with the use of innovative technologies. The
results of the survey and interviews will be summarized and evaluated. It
may be determined that while demonstrated technologies may be acquired

-------
using established procurement methods, these same methods will not
necessarily lend themselves to the procurement of innovative treatment
technologies. It is expected that innovative treatment technologies will also
pose challenges when it comes to their design, scaling up, and operational
parameters. It is also anticipated that corporate acquisitions and mergers
could play a role, as many of these companies are ripe for takeover.
The difficulties to overcome when using innovative technologies may
sometimes seem to outweigh the advantages the technology may provide.
While innovative technologies often promise lower treatment levels, or
lower costs, these claims are often premature due to the lack of actual
operational data. It occasionally turns out that the technology cannot be
implemented at all when it fails to perform in the field as expected.
Conclusions:
Certain steps may be taken to increase the practicality of applying innovative
treatment technologies, however, there will always be certain risks associated
with the application of these technologies. The Agency must be willing to
accept these risks if it is to seriously pursue innovative treatment
technologies as reasonable alternatives for the remediation of Superfund
sites.

NINTH AVENUE DUMP: THE EVOLUTION OF A SUPERFUND REMEDY
Allison L. Hiltner
U.S. EPA Region V
(312) 353-6417
ABSTRACT
The Ninth Avenue Dump Superfund Site is a former wetlands area in Gary,
Indiana, which was operated as a "midnight dump" from 1973 to 1975. State
inspectors discovered that several hundred thousand gallons of oils, solvents,
paint wastes, acids, and thousands of drums had been buried at the site. The
site was placed on the National Priorities List in 1983. In 1988, after several
removal actions and an extensive Remedial Investigation/Feasibility Study
(RI/FS), an interim remedy Record of Decision was issued by the United
States Environmental Protection Agency (USEPA) to address a highly
contaminated oil phase present under much of the site. USEPA issued a
Unilateral Order in 1988 and private parties completed construction of the
interim remedy in late 1991.
In this paper, I will describe the evolution of the remedy from ROD signature,
through design, to construction completion. The ROD called for construction
of a soil/bentonite slurry wall, installation of a oil/groundwater extraction
and groundwater reinjection system, oil storage, and reinjection of excess
water due to rainfall to the aquifer outside the slurry wall. Several changes
were made through remedial design and construction, although the basic
components of the remedy remained the same. In the end, the area
encompassed by the slurry wall increased from 9 to 17 acres while estimates of
the volume of extractable oil varied from 500,000 to 10,000 gallons. The
estimated flow rate of excess water to be discharged outside the slurry wall
increased from 1 gpm to 30 gpm, requiring a change in the discharge point
from the aquifer immediately outside the slurry wall to a river 11/4 miles
away, and a change in the treatment system from a few carbon columns to a
10,000 sq. ft. treatment plant requiring full-time operators. The estimated cost
of construction grew from $2 to $12 million.
This site was well characterized during the RI/FS, and changes from the ROD
to RD were not entirely due to lack of sufficient RI/FS information, as is often
the case with Superfund remedies. Some of the reasons for the increase in
scope of the remedy include the issuance of a final remedy ROD in 1989,
which required changes to the interim remedy, and differences in
assumptions used from the RI/FS to the design in developing volume and
area estimates.

-------
The Agency's experience at this site provides an example of the uncertainties
inherent in the Superfund process. I will discuss the reasons behind the
changes made to the ROD during design and construction and lessons learned
throughout the process. I will discuss recommendations for future RODs
based on the experience at this site.

CARBON RIVER MERCURY SITE:
A RISK-BASED APPROACH FOR A REMEDIAL
INVESTIGATION/FEASIBILITY STUDY
Sean P. Hogan
Region IX
(415) 744-2233 or FTS 484-2233
ABSTRACT
The Carson River Mercury Site (CRMS) is a result of ore processing techniques
which were employed during the Comstock Lode in Nevada (1859-1901). Mercury
was used in amalgamation processes to extract gold and silver from ore. It is
estimated that up to 7,500 tons of mercury entered the Carson River system during
this period. The current definition of the site includes tailing piles remaining at
historic mill sites and approximately 100 miles of the Carson River extending
through Lahontan Reservoir and terminating at the Carson Lake and Stillwater
wetlands. The principal human health risks associated with the contamination are
ingestion of mercury-contaminated soils and ingestion of fish, waterfowl, or any
other animals with unacceptable levels of mercury accumulated in muscle tissue or
other portions of the animal. The principal ecological risk is the bioaccumulation
and transfer of mercury throughout the foodweb.
Reducing the human health risks associated with the ingestion of mercury-
contaminated soils is relatively straight-forward. However, reducing the ecological
and human health risks associated with the bioaccumulation and transfer of
mercury throughout the foodweb is a very complex problem for which no solutions
currently exist. Therefore, we have developed an approach for the RI/FS which
includes three operable units. The objectives for the first operable unit are as
follows:
•	characterize and control human health risks associated with mercury-
contaminated soils
•	assess all of the human health risks associated with mercury
contamination
•	assess the ecological risks associated with mercury-contaminated
sediments in aquatic environments and develop cleanup criteria
•	investigate the process of mercury methylation in the river system with the
assistance of the Athens Lab.
The scope of operable units two and three largely depends on the ecological
assessment performed in operable unit one which will identify the specific impacts
associated with mercury contamination and will determine cleanup criteria for
sediments. With this information, EPA can evaluate the ecological impacts, the
degree of remediation required to alleviate the impacts, and the technical and
economical feasibility of remediation before selecting a strategy for the investigation
and remediation of the river system.

DATA USEABILITY IN RI/FS PROJECTS
Cynthia Kaleri
U.S. EPA, Region VI
ABSTRACT
In October 1990, EPA issued an Interim Final Guidance for Data Useability in
Risk Assessment. This guidance supplements that information currently found
in the RAGS Guidance and touches upon many problems frequently encountered
in collecting, analyzing, and evaluating data at Superfund sites for Risk
Assessment. This guidance is one in a series of document to be produced which
may help RPMs ascertain the type of data necessary to produce reliable RI/FS
reports. Risk assessment was targeted as the first prototype guidance since the
quality of data needed in risk assessments is often more rigid than other data
objectives in the RI/FS. Collection and evaluation of a specified quality and/or
quantity of data is the focus of the Data Useability Guidance Documents. For
example, in the Risk Assessment document, minimum data requirements are
identified and outlined in addition to that data desired by the risk assessor for
completion of an adequate risk assessment report.
My presentation will highlight useful information available in this document that
was used in evaluating the sampling plan for two sites in Region 6, since the
guidance was issued after the site WPs. In addition, these two sites were used as
a protocol in evaluating data for use in the risk assessment; the guidance is
currently undergoing revisions based on real site applications at these two sites.
My presentation will include a synopsis of the considerations which need to be
addressed when using the criteria in the guidance for conducting adequate risk
assessments. Information to be covered will include the current protocol being
used for lead cleanup (LEAD 0.5 Model, formerly LEAD .04) and standard
default assumptions for various RME scenarios. Questions can be entertained
which pertain to RAGS, as time allows.

INCINERATION AT THE MOTCO SUPERFUND SITE,
LAMARQUE, TEXAS
Mary Ann LaBarre
U.S. EPA, Region VI
ABSTRACT
Background:
In October of 1987, EPA entered into a Consent Decree with the MOTCO Trust
Group to incinerate 60,000 yd^ of sludges/soils and 7 million gallons of organic
liquids. A fixed-price contract was awarded to IT in January 1988. IT underbid
the ROD estimate by approximately $15 million. Two incinerators were
constructed on-site during the fall of 1989; one incinerator to burn liquids only
and one incinerator to burn solids and liquids. EPA approved the trial burn plan
in May 1990 for a trial burn on each incinerator. The first trial burn was in
October 1990 on the liquids incinerator. The second trial burn on the solids
incinerator was in July 1991. The trial burn consisted of two tests, one in the
pyrolytic mode, and one in the oxidative mode. EPA was informed in August
1991 that the test in the pyrolytic mode failed. Unsuccessful attempts to redo the
trial burn were made in the fall of 1991. IT had intended to redo the trial burn in
February 1992. This presentation will discuss some of the difficulties
encountered with the incinerator and possible solutions.
Major Technical Issues:
•	Waste Handling
Slagging
•	Salt Carryover
•	Emergency bypasses
Status of Project:
In December 1991, IT filed suit against the PRPs for breach of contract. IT is
presently demobilizing from the site, and the Trust Group is in the process of
evaluating other contractors.

EXTRAVAGANT, BUT NECESSARY CONTROLS ON SUPERFUND AIR
STRIPPER DESIGNS
Cesar Lee, P.E.
EPA Region HI
(FTS) 597-8257
ABSTRACT
Although Air Stripping systems are in common use for the treatment of
municipal water supplies when used at Superfund sites, there is the perception
that some rare and horribly toxic compounds are being handled. Therefore, the
onus falls upon the designer to account for every drop of the contamination
from:
a.	pumping
b.	to treatment
c.	to final disposal.
"You 're going to pump that poison out of the ground
and put it into the air."
This may be taken as the emotional opinion of residents in the
neighborhood of a proposed Air Stripper, but there is some truth to that opinion.
This paper will examine the following aspects of an Air Stripper:
a.	vulnerable areas of such a system
b.	realities underlying public perception
c.	use of controls to minimize and account for risks, both real and
perceived.

NPL BASE CLOSURE IN CALIFORNIA:
Can a New Committee Combining Managers from EPA, DoD and the State
Expedite Hazardous Waste Cleanup and Land Transfer?
Barbara Maco
Region IX
484-2383 (FTS)
ABSTRACT
Reducing the U.S. Defense budget translates into a 25% reduction in the military
forces and the transfer of many military bases. Since 8 of the 15 closing military
bases nationwide are located in California, expeditious base closure is a top
agenda item for many California Members of Congress and for Governor Wilson.
Federal legislation specifies where and when certain land transfer will occur and
a State Executive Order provides for whom will participate in the base closure
program.
In the past two years, EPA has sought to reconcile the national priority of base
closure with the Superfund mandate. At issue are the legal authority and
resources necessary for effective EPA/State oversight of base closure, how
CERCLA hinders or can hasten base closure, available technology, state
initiatives, and community involvement. To implement the program and resolve
any conflicts resulting from these Federal and State directives, Region 9, the
State, and DoD recently formed the California Base Closure Environmental
Committee (CBCEC). This presentation would explore the CBCEC role in base
closure issues affecting Superfund.
The Committee consists of first- and second-level managers from Region 9, the
DoD environmental and base closure programs and the three branches, and the
California EPA and its Office of Planning and'Research (the Governor's
designated lead agency). Since its first meeting in December, 1991, the CBCEC's
first priority has been reviewing draft procedures for documenting and
transferring clean parcels of land. Issues include the need for new DoD studies
and documentation, the definition of NPL sites for a federal facility, and how to
interpret the CERCLA Section 120(h)(3) requirement that all remedial action be
taken prior to deed transfer. Region 9 is holding parallel discussions with HQ
and other regions to reach a consensus on these issues and on whether resources
should be devoted to this "pre-RI/FS review."
Equally important is how to involve the numerous affected businesses,
environmental groups, and legislators, as mandated by the Governor's Executive
Order, without sacrificing the focus on the original environmental objectives of
the Committee. Proposals include forming an Executive Committee, holding
briefings and workshops, and expanding membership at a later date.

-------
The work of the Committee has just begun and the issues to resolve are many.
However, its work will influence the other seven closing bases nationwide and
those that will be included in the 1993 and 1995 Base Closure and Realignment
Commission Reports.

EVOLVING APPROACH TO STREAMLINING THE RISK ASSESSMENT
PROCESS AT SOUTHERN CALIFORNIA GROUNDWATER
CONTAMINATION SITES
Kevin Mayer
and
Wayne Praskins
Region IX
ABSTRACT
Experience throughout Region 9 suggests that Baseline Risk Assessments for
most groundwater contamination sites have served solely to confirm the default
cleanup objectives (MCLs or non-zero MCLGs), despite the consumption of
significant time and resources. The need for a simplified RA process became
quite apparent for sites and operable units in three large groundwater basins in
Southern California. The similarities of conditions at these sites (alluvial basins
contaminated with common chlorinated solvents) have allowed the RPMs to
increasingly rely on previous work to avoid duplicative expenditure time and
resources.
At the San Fernando Site, a standard Baseline Risk Assessment had been
conducted for the contaminant plume that constituted the Glendale Operable
Unit. A small, but significant, step toward streamlining was negotiated between
RPMs, EPA toxicologists, and the consultants to expand the RA for the Glendale
OU into the San Fernando Valley basinwide RA simply by the addition of the
basinwide water quality data set for recalculation.
Several simplifying assumptions are being made in the risk assessment for the
Baldwin Park OU of the San Gabriel Valley Sites. Only a small subset of the
available ground water data are being used to estimate exposure; exposure via
inhalation will be estimated by assuming an additional dosage equal to the
dosage via ingestion; exposure to soil contamination will not be addressed since
its remediation is not a goal of this operable unit; and the exposure analysis will
not try to account for the complexities of water distribution in the Valley. The
RA will briefly discuss how these simplifying assumptions may over- or
underestimate risk. The toxicity assessment requires little new analysis beyond
information gathered for other OUs and sites with chlorinated solvents in ground
water.
The approach to the RA for the Newmark Site in San Bernardino Valley will
make use of both the exposure pathway analyses and the toxicity assessments for
previous sites. The only unique information to be presented is the list of
compounds of concern detected during EPA's subsurface investigation and the
statistical treatment of concentration data. Establishment of remedial objectives
will be simplified by a brief presentation of the risk calculations for the

-------
compounds of concern at their respective MCLs (the default cleanup goals)
Cleanup goals for unsaturated zone contamination at identified sources are to be
established with consideration for protection of groundwater, not as a separate
risk exposure pathway.
Many groundwater contamination sites involve conditions that justify a vastly
simplified process based on extensive previous experience. It was fortuitous that
the applicable experience was concentrated in a single section to facilitate
identification and implementation of streamlined processes. Coordination with
regional toxicologists and ORCs as well as other RPMs helps to ensure that
requirements of the NCP are fulfilled.

BASE CLOSURE ISSUES AT NPL FACILITIES
Katherine Moore
US EPA, Region IX
(415) 744-2407
ABSTRACT
In 1988, Congress passed the Base Closure and Realignment Act (BCRA)
which required the Department of Defense (DOD) to close and realign
military installations. Currently, the Comprehensive Environmental
Response, Compensation, and Liability Act (CERCLA) Section 120(h) requires
Federal Facilities to take all necessary remedial actions before selling their
property.
The Commission on Base Closure and Realignment recommended George
Air Force Base (AFB) and Mather AFB in California for closure in Round I.
George AFB is scheduled to close on December 31, 1992; Mather on September
30, 1993. The concurrent implementation of CERCLA and BCRA has raised a
number of conflicting issues to the EPA, Air Force, and State Remedial Project
Managers (RPMs). The primary concerns are grouped as follows:
•	Investigation and Clean Up Prioritization: CERCLA site
prioritization is determined based upon protection of human
health and the environment, while BCRA prioritization appears
to be financially motivated.
•	Parcelization: As each facility closes, the RPMs will most likely
be required to make a determination if the specific parcels have
had all necessary remedial action taken at that location. CERCLA
guidelines, including risk assessment procedures, complicate
this finite decision until the entire Federal Facility has been
characterized and remediated.
•	Site Acceleration: In order to meet the mandates of BCRA and
the economic desires of the community, the Federal Facility
Agreement (FFA) schedules may need to be accelerated. This will
most likely translate into technical, program, and resource
impacts.

VINYL CHLORIDE MIGRATION IN SOIL GAS AT A MUNICIPAL
LANDFILL SUPERFUND SITE
Bret Moxley
U.S. EPA Region IX
FTS 484-2228
(415) 744-2228
ABSTRACT
The conventional premise on soil gas plumes emanating from landfills is that
methane will delineate the leading edge of the soil gas plume. This is because
methane is typically the lightest and most prevalent constituent in the landfill
gas. Recent soil gas sampling at the Fresno Sanitary Landfill Superfund Site has
revealed that vinyl chloride from the landfill has migrated as much as 500 feet
beyond the edge of the methane plume. This discussion will include the soil gas
sampling strategy, technical considerations and procedures, costs, results, and
possible mechanisms for this apparent soil gas migration anomaly.

ABSTRACT
Vinyl Chloride soil gas migration under several homes near the Fresno Sanitary
Landfill Superfund Site has necessitated ambient air monitoring for vinyl
chloride in these homes. This discussion will include the ambient air monitoring
strategy which provided a quantitation limit for vinyl chloride of 0.2 ppbv.
Discussion will include technical considerations and procedures, costs, a three-
tiered action level plan, remediation and relocation contingencies, community
relations issues, and results from the first phase of sampling.

STREAMLINING ECOLOGICAL ASSESSMENT AT NPL FEDERAL
FACILITIES
George Nangles
U.S. EPA, Region IX
(415) 744-2407
ABSTRACT
NCP requires that the baseline risk assessment in the RI/FS "characterize the
current and potential threats to human health and the environment".
CERCLA/SARA requires protection of the environment. The NCP specifies that
"environmental evaluations shall assess threats to sensitive habitats and critical
habitats of Endangered Species". Currently there is little consistency, and limited
efficiency, within ecological risk assessment at Superfund sites. How can we
streamline the process of ecological assessment without ignoring the site-specific
nature of ecological stress? This paper focuses on the tools that RPMs can use to
accomplish Problem Formulation, Exposure Assessment, Effects Assessment,
Risk Characterization, Feasibility Study, and Remedial Design in a streamlined,
protective, and widely accepted fashion. MCB Camp Pendleton, CA is the
specific example.
Valuable Documentation: ECO Update circulars, Rapid Bioassessment
Protocols, EPA Technical Assistance Directory, Environmental Assessment
documents, ASTM and EPA protocols for sediment and water toxicity, and
references taken from AQUIRE database.
Technical Support: The Biological Technical Assistance Group (BTAG) is a
valuable source of advice on QA/QC, DQO's, fate, sampling and analysis, and
general direction. BTAGs typically include natural resource trustees and
consultants as well as EPA staff.
Team Building: A "team" approach with open communication between EPA,
trustees, and the Navy's CLEAN contractor has saved tremendous amounts of
time and frustration.
Computer and Information Resources: EPA has excellent GIS facilities which
may be cost-prohibitive for the Navy or their contractors to procure. Using Inter-
Agency Agreements, EPA can play a key role in facilitating effective and efficient
management of site-specific geophysical, GPS, ecological mapping, hydrologic
mapping, toxicity, and contaminant concentration data. One key element of
streamlining involves specification of electronic data formats and procedures at
the outset of RI/FS work. Precise specification of such formats and procedures
can facilitate efficient data acquisition and analysis; allowing GIS, Data
Validation, and Data Quality Tracking of QA/QC outliers to be accomplished
more efficiently. Capturing ASCII files from AQUIRE and IRIS database and

-------
using them in a GIS work environment is yet another valuable technique.
Objectives and budget limitations should be clearly, efficiently, and realistically
specified to avoid excess.
Sampling and Analysis Techniques: GIS and intake models can help to narrow
down the scope of expensive and time-consuming sampling and analysis. With
this focus, passive sampling with GC/MS analysis, bioassays, and direct tissue
sampling can be selected (in the context of schedule and budget limitations) in
addition to active sampling with chemical analysis of media. Another
convention we are exploring is the formulation of site-specific objective functions
for minimization of ecological stress in remediation design.

SITES WITH MULTI SOURCE/MULTI SITE GROUNDWATER
CONTAMINATION PROBLEMS

ABSTRACT
The Sand Creek Superfund Site is comprised of four different groundwater
contamination sources and is part of a larger groundwater system which is
influenced by five Superfund sites, several RCRA sites and an unknown
number of other active or abandoned facilities. This groundwater system
encompasses parts of the City and County of Denver, the City of Commerce
City, and South Adams County, in an area which was one of the industrial
backbones of the State of Colorado for almost a century.
Evaluating the impact of these sites on the groundwater has caused EPA to
develop several different mechanisms to insure coordination of activities and
information. This paper will describe the evolution of EPA's information
transfer mechanisms, and focus on the difficulties encountered in avoiding
duplication of effort and maintaining consistent approaches to investigating
and remediating the groundwater with respect to the Sand Creek Site.

ASSESSING LOW PROBABILITY HAZARD SITES AT FEDERAL
FACILITIES

(206) 553-6638
ABSTRACT
Federal Facilities listed on the National Priorities List present unique problems
for site characterization. Federal Facilities are typically associated with a large
number of potential hazardous sites which vary significantly in size, age,
complexity, and potential for environmental contamination.
CERCLA provides a rigorous decision process for determining the need to
perform remedial actions at hazardous waste sites. Remedial decisions are based
on the concept of acceptable risk. The extent of contamination associated with
individual sites at a Federal Facility ranges from those sites which are known to
exceed the risk threshold for remedial action, to sites which have a low
probability of presenting an unacceptable risk. Sites which fall at the latter end
of the spectrum are categorized as "Low Probability Hazard Sites" or LPHSs.
LPHSs may not warrant the level of remedial investigation associated with
typical Superfund sites which are known to present or have a high probability of
presenting an unacceptable risk to human health and the environment.
A methodology to assess the need for further investigation and action at LPHSs
has been applied at several Region 10 Federal Facilities. This screening-level
approach is based on the concepts of qualitative risk assessment Data Quality
Objectives described in several CERCLA RI/FS Guidance documents. This
methodology is an effective process for prioritizing site cleanups, for reaching
early decisions, and for focusing the scope of Remedial Investigation/Feasibility
Studies.

REVEGETATION AT ABANDONED ASBESTOS MINE SUPERFUND SITES
Richard Procunier
Region IX, H-6-2
FTS 484-2219
ABSTRACT
In 1980, asbestos was detected in the California Aqueduct south of Huron.
Studies have shown that, during floods, asbestos-laden water and sediments
sometimes flow into the aqueduct. In a 1983 survey, two abandoned mines
were identified as the most likely significant sources of the asbestos. The two
sites, Atlas and Johns-Manville/Coalinga Asbestos Mines were subsequently
added to the NPL. Asbestos exposure also results from vehicle use on
unpaved roads and trails which releases asbestos fibers into the atmosphere
where they are inhaled by users of a nearby Bureau of Land Management
Recreational Area.
EPA's clean-up plan for these sites includes engineering and institutional
controls to minimize the release of asbestos with the following elements:
stream diversions, sediment trapping dams, slope stabilization, limiting
access, disposing of debris, paving roads, deed restrictions, and revegetation.
Revegetation poses some particular problems in the unique serpentine soils.
It must first be determined if revegetation is a practical way to minimize
erosion of the disturbed areas before a full-scale implementation of the pilot
project is attempted. This makes the RD/RA phase particularly interesting.

STRATEGY FOR CONDUCTING AN RI/FS AT THE HARBOR ISLAND
SUPERFUND SITE, SEATTLE, WA
Keith A. Rose
EPA, Region X
(206) 553-7721
ABSTRACT
Harbor Island is a 400-acre industrial island located at the mouth of the Duwamish
River in Seattle, Washington. The island was constructed at the turn of the century
with sediments dredged from the Duwamish River. The island was listed on the
NPL in 1983 primarily because of elevated levels of lead in the air, soil, and marine
sediments due to a lead smelter which operated on the island for 47 years. In
addition to the smelter, the site includes other sources of hazardous substances
including two major shipyards, several metal foundries and plating operations, a
scrap metal recycling operation, and several petroleum tank farms.
Most of the unpaved surface soil on the island has levels of lead above the cleanup
action level of 1,000 ppm. In addition, there are localized areas of soil with levels of
arsenic, chromium, PCBs, PAHs, and petroleum hydrocarbons above the cleanup
action level. Sediments in several areas of the surrounding waterways have been
documented to contain concentrations of copper, lead, zinc, mercury, arsenic, PAHs,
PCBs, and methylphenols exceeding the State marine sediment standards.
Groundwater quality at several monitoring wells on the island exceeds MCLs for
arsenic, cadmium, chromium, lead, selenium, benzene, and ethylbenzene.
EPA initiated a Phase I RI in 1988 which focused on soil contamination at several
facilities where high levels of hazardous substances were suspected and installed 20
groundwater monitoring wells to assess water quality. EPA is now completing a
Phase II RI/FS which is a comprehensive sampling of soil, groundwater, and
marine sediments to completely characterize the nature and extent of
contamination and to select the appropriate remedial actions for this site.
The investigation of this Superfund site was complex due to its numerous sources
of hazardous substances and due to its unique location, being surrounded by water
and a marine ecosystem. Methods were developed for conducting the RI/FS which
took into consideration the above site complexities and allowed completion of the
RI/FS in a reasonable timeframe. These methods included: 1) a two-phased
sampling strategy for determining the nature and extent of contamination, 2) a
customized Geographic Information System (GIS) for data management and
evaluation, 3) a two-phased groundwater model approach to predict the transport of
contaminants in groundwater, and 4) a generic soil treatability study to determine
which technologies would be most effective for soil remedial actions.

(303) 294-1975
ABSTRACT
Most of the ground water wells at the Defense Depot in Ogden, Utah (an NPL
Site) were sediment producing. This resulted in turbid samples which contained
sediment as high as 25% by volume. EPA and the State of Utah believed that
turbid samples were not representative of the aquifer and set a criterion of five
nephelometric turbidity unit (5NTU) or less for future ground water sampling.
A bladder pump subsequently was used to collect ground water samples which
had turbidity of 5NTU or less. Initially the vinyl chloride concentration was
around 2 ppb. After ensuring that samples were turbidity free, the vinyl chloride
concentration increased five-fold. Because MCL for vinyl chloride is 2 ppb, a
potential no action Record of Decision was changed into an action ROD.

BALANCE OF PRIORITIES
A.V. Spencer
Region VIII
(303) 293-1648
ABSTRACT
As an RPM, there are many responsibilities to fulfill, duties to perform and
issues to resolve. The objective of an RPM is to perform, as gracefully as
possible, a very delicate juggling act. The following important priorities are a
few examples of the most delicate plates we juggle:
•	Building a cohesive, results-oriented team. Superfund is a team
effort involving core teams and other team experts as necessary.
The team approach is essential to accomplishing it all. However,
with this myriad of people, it is very difficult to get everyone
together for a team meeting. The goal, of course, is to obtain a
team consent on an issue or approach.
•	There is a careful balance between "fighting fires", short-term
duties to advance the project, and "envisioning the forest", long
term project planning. Site planning is a critical step to guide the
project. Yet, there are always many issues to research and
resolve.
•	Building good, working relationships with external parties.
Communications with the State, PRPs, contractors, and the
community are vital to the success of the project.
•	Resolving technical issues are challenging; however, in
Superfund, the technical issues have become intertwined with
the legal morass.
Superfund is a technically complex, multi-media specialized industry.
Moreover, Superfund has evolved to a very cumbersome process. The RPM
must obtain an informed consent from internal and external parties in order
to proceed toward cleanup. There are many hoops to jump through while
juggling the plates. The process itself has become overburdensome. Have we
hit a point of diminishing returns? Are we proceeding in the correct
direction? Are we doing what's right and not just following the process that
we created?
We must not let ourselves get so caught up in the "PROCESS". We must face
our barriers and obstacles as a challenge to be confronted head on. We have

-------
built some of the most frustrating barriers into the process. We've agonized
through the process a few times, and now it's time to revise our ways of
doing business. We have to find new paths around, over, and under, but
better yet, let's create entirely new and different direct courses of action. It is
not easy and there are risks involved. Any deviations from the normal
process are very arduous.
However, there is hope. The most positive aspect of the revitalization
initiative, for everyone involved, is now strongly encouraged to look for
innovative ways to conduct business. It is already stirring creativity in teams,
management, and headquarters. Most importantly, management and other
team members may be open to innovative approaches. Let's take advantage
of this creative time to share and discuss the ideas for innovative approaches.
Which plates are your most delicate?

IDENTIFICATION OF A MULTI-AQUIFER GROUND WATER CROSS
CONTAMINATION PROBLEM USING BOREHOLE GEOPHYSICAL
METHODS
Michael Towle
U.S. EPA, Region in
(FTS) 597-8309
ABSTRACT
Abandoned industrial and public supply wells and improperly constructed
monitoring wells, completed as open holes penetrating multiple water-bearing
intervals in the Stockton Formation, short circuit the ground water flow system
and act as conduits for contaminant transport. Borehole geophysical methods
were used to construct a three-dimensional lithostratigraphic model, identify
fluid-producing and fluid-receiving zones (fractures), measure vertical borehole
fluid movement, and serve as the basis for proper construction of monitoring
wells at a Superfund site in Hatboro, PA. Natural-gamma, single-point
resistance, caliper, fluid-temperature, and fluid-resistivity logs were run in 16
boreholes 149 to 470 feet deep.
The lithostratigraphic model of the dipping sedimentary rocks of the Triassic
Stockton Formation is primarily based on natural-gamma, single-point
resistance, and caliper logs. Geophysical logs from one borehole were compared
to a 200-foot long rock core, from that borehole, to determine the relative
response of the geophysical logs to lithology. This comparison was used as the
basis for interpretation of the geophysical logs of the other boreholes. The
interpreted lithostratigraphy correlates closely from borehole to borehole.
Fluid-producing and fluid-receiving zones were identified based on caliper,
single-point resistance, fluid-resistivity, and fluid-temperature logs. The
direction and rate of borehole fluid movement was determined by injecting a
slug of high-conductance fluid at different depths in 15 of the boreholes and
monitoring the movement of the slug with the fluid-resistivity tool. Downward
fluid movement at rates up to 6 gallons per minute was measured in 13
boreholes. Borehole fluid moving from the shallow to the deeper part of the
aquifer system, from all nine boreholes sampled, contained detectable
concentrations of volatile organic compounds, confirming that cross-
contamination is occurring.
Borehole geophysical logs were used as the basis for construction of monitoring
well-clusters to prevent cross-examination. A deep borehole was drilled and
logged at each cluster location. The deep borehole was reconstructed so that it
was open only to the deepest water-bearing interval. Two additional boreholes
open to shallower water-bearing intervals were then constructed.

-------
A combination of borehole geophysics, measurement of vertical borehole flow,
and sampling of the fluid moving in boreholes was an effective method to
identify a ground water cross-contamination problem. Borehole geophysical logs
and measurement of borehole fluid movement provided the location of fluid-
producing and fluid-receiving fractures in the boreholes and defined zones of
borehole flow.

USING COOPERATIVE AGREEMENTS TO FUND MULTI-SOURCE
ENFORCEMENT WORK
SAN FERNANDO VALLEY SUPERFUND SITE RI/FS

EPA Region IX
ABSTRACT
In 1986, EPA placed four sites within the San Fernando Valley on the National Priorities
List (NPL). Each site boundary encompasses an area in which production wells
produced ground water containing concentrations of TCE and PCE above State and
Federal standards (MCLs and SALs) in 1984. EPA is managing the four areas as one
large site referred to as the San Fernando Valley Superfund Site. The study area of these
large site includes the four NPL sites and adjacent areas where ground water
contamination is known or presumed to have migrated.
The San Fernando Valley covers approximately 122,800 acres and the ground water
provides a source of drinking water for more than 600,000 residents in the Los Angeles
area. The ground water contamination plume extends over 12 miles in length and is
from hundreds of different sources.
The overall objectives of this project include: 1) to protect human health and the
environment, 2) to characterize the nature and extent of the ground water
contamination in the San Fernando Valley Ground Water Basin, 3) to develop and
implement and effective remediation for the ground water contamination, 4) to identify
potentially responsible parties (PRPs) and link them to the ground water contamination,
and 5) to compel these PRPs to perform the work and pay for past and future EPA costs.
To help achieve these objectives and to strengthen our enforcement program, EPA
entered into a cooperative agreement with the California State Water Resources Control
Board (State Board) in September 1989 to enable the Regional Water Quality Control
Board, Los Angeles Region (Regional Board) to assist with source identification in the
San Fernando Valley Basin. Responsibility for water quality planning and protection is
shared by the State Board and its regulatory arm at the regional level, the Regional
Board.
The funding has enabled the Regional Board to increase the number of staff working on
source investigations in San Fernando from three to eleven. EPA has worked closely
with the Regional Board to develop an aggressive and highly successful source
identification program for a large, multi-source site without tapping contractor or other
project resources. EPA is using the results of the Regional Board's work to develop
strong enforcement cases and to preliminarily identify good candidates for special
notice. In addition, EPA funding allows the SWRCB to redirect State funds for source
remediation.

REMEDIAL ACTION USING REMOVAL AUTHORITIES AT THE
SOUTHEAST ROCKFORD GROUND WATER CONTAMINATION SITE
ROCKFORD, ILLINOIS
Karen Vendl
ABSTRACT
The Southeast Rockford Ground Water Contamination Site is a residential area
with private wells that is located near the City of Rockford, Illinois. A removal
action was done in 1990 to connect residences to City water whose wells had
contamination above Removal Action Levels. The remainder of the affected
homes had levels of contaminants below Removal Action Levels, but above
Maximum Contaminant Levels. Under an operable unit of the remedial effort,
these homes were connected to city water using removal authorities. The use of
removal authorities allowed USEPA to proceed from signature of the Record of
Decision to construction in 34 days, thus removing the public health threat at
least a year earlier than if remedial authorities had been used.

REMEDIAL DESIGN/REMEDIAL ACTION "NEGOTIATIONS",
THE DEPARTMENT OF JUSTICE, AND TIME
Laura O. Williams
U.S. Environmental Protection Agency
Region VIII
(303) 293-1531
(FTS) 330-1531
ABSTRACT
Section 122 of CERCLA requires that all Remedial Design/ Remedial Action
(RD/RA) settlements with Potentially Responsible Parties (PRP) be finalized as
judicial Consent Decrees (CD). The 1989 OSWER Directive 9837.2, Enforcement
Project Management Handbook (Guidance), recommends coordination by the RPM
with the Federal natural resources trustees and the State, as well as the required
"close coordination" with ORC, OECM, OWPE, and last, but not least, the
Department of Justice (DOJ) during the RD/RA negotiations process.
The "negotiations" process informally begins upon review of the PRP search and
the determination by the Region that there are PRPs who appear to be viable,
capable of properly implementing the remedy, and who may be willing to settle. The
Guidance recommends submittal by the Region of a pre-referral package to DOJ at
least 60 days prior to the issuance of the RD/RA special notice letters. The DOJ case
attorney is considered an important legal resource to the Region and is identified as
a fully participating member of the negotiations team. The DOJ attorney and
appropriate management are also responsible for review of the initial draft of the
CD before it is sent to the PRPs, as well as subsequent redrafts. The DOJ case attorney
represents DOJ's view of the case and is responsible for providing consistency with
and insight into other enforcement cases.
The formal settlement process begins with the issuance of special notice letters to
the PRPs. This begins a 60-day moratorium period in which the PRPs can make a
"Good Faith Offer" to undertake or finance the RD/RA. If such an Offer is received,
the moratorium is extended an additional 60 days to allow EPA and the PRPs to
attain a mutually agreeable CD. The Regional Administrator can extend the
moratorium yet another 30 days if agreement seems to be imminent. Once
agreement has been reached, the CD is signed by the PRPs and the Regional
Administrator; and then forwarded to DOJ with a referral package developed by
ORC.
At this time, you're probably pretty happy because you met your target and you can
finally begin RD/RA activities! But when does the CD become effective and,
therefore, enforceable? And what impact is this likely to have on your site schedule?
The potential horrors of the "after-negotiations" process are illustrated by the actual
events which befell the Woodbury Chemical Company Site.
