Selected Remedial Alternative
for the
National Presto Industries, Inc. Site
Eau Claire, Wisconsin
Site Name and Location
National Presto Industries, Inc. Site
3925 N. Hastings Way
Eau Claire, Wisconsin 54703
Statement of Basis and Purpose
This decision document presents the selected remedial action for the National Presto Industries, Inc.
Site ("NPI Site" or 'the Site") in Eau Claire, Wisconsin, which was chosen in accordance with the
requirements of the Comprehensive Environmental Response, Compensation, and Liability Act of
1980 ("CERCLA"), as amended by the Superfund Amendments and Reauthorization Act of 1986
("SARA") and, to the extent practicable, the National Oil and Hazardous Substances Pollution
Contingency Plan ("NCP"). This decision document explains the factual and legal basis for
selecting the remedy for the NPI Site. The information supporting this remedial action decision is
contained in the administrative record for this Site. The State of Wisconsin concurs on the selected
remedy.

Assessment of the Site
Actual or threatened releases of hazardous substances. from this Site, if not addressed by
implementing the response action selected in this Record of Decision ("ROD"), may present an
imminent and substantial endangerment to public health, welfare, or the environment.
Description of the Selected Remedy
The selected remedy is the final remedy for the Site. In addition to those response actions previously
completed and currently underway at the NPI Site, the United States Environmental Protection
Agency ("U.S. EPA") has determined that the following additional measures should be implemented
in order to fully address-all threats to human health and the environment posed by contamination at
the Site:
• Melby Road and East Disposal Sites: installation of a soil vapor extraction system
("SVE") at the Melby Road Disposal Site, removal of concentrated wastes (if any)
identified by the SVE at the Melby Road Disposal Site, excavation and consolidation
-------
of East Disposal Site wastes with Melby Road wastes, and installation of a multi-
layer cap compliant with Wisconsin Administrative Code Chapter NR 660 over
combined wastes at the Melby Road Disposal Site;
• Drainage Ditch 3: removal of contaminated soils and consolidation with wastes at
the Melby Road Disposal Site;
• Dry Wells 2 and 5: removal of contaminated soils and disposal in an off-site landfill;
• Plume 1-2: continued operation of the two-column air stripper at the leading edge
of the ground-water contaminant plume, continued operation of an on-site pump and
treat system to prevent the off-site migration of contaminated ground water, and long
term ground-water monitoring of Plume 1-2;
• Plumes 3 and 4: continued operation of an on-site pump and treat system to prevent
the off-site migration of contaminated ground water, long-term ground-water
monitoring of Plumes 3 and 4, and surface water sampling in Lake Hallie; and
• Plume 5: long-term ground-water monitoring of Plume 5 and surface water sampling
in Lake Hallie.
Declaration of Statutory Determinations
The selected remedy is protective of human health and the environment, complies with federal and
state requirements that are legally applicable or relevant and appropriate to the remedial action, and
is cost effective. The remedy utilizes permanent solutions and alternative treatment (or resource
recovery) technologies to the maximum extent practicable, and satisfies the statutory preference for
remedies that employ treatment that reduces toxicity, mobility, or volume as a principal element.
Because this remedy will result in hazardous substances remaining on site above health-based levels,
a review will be conducted every five years after commencement of remedial action to ensure that
the remedy continues to provide adequate protection of human health and the environment.

DECISION SUMMARY OF FINAL REMEDIAL ACTION
NATIONAL PRESTO INDUSTRIES, INC. SITE
EAU CLAIRE, WISCONSIN
I. SITE NAME, LOCATION AND DESCRIPTION
The National Presto Industries, Inc. Site ("NPI Site" or 'the Site") is located at 3925 N. Hastings
Way in Eau Claire, Wisconsin (Figure 1). The Site lies within the City of Eau Claire, with the
exception of approximately 9 acres in the extreme eastern part of the property, which are located in
the Town of Hallie, and approximately 4 acres in the extreme southern part of the property, which
are located in the Town of Seymour. Most of the NPI Site, comprising approximately 320 acres, is
situated in Chippewa County; a portion is located along the northern border of Eau Claire County.
The immediate vicinity of the Site is characterized by light residential and commercial development.
The unincorporated Town of Hallie is located north and east of the Site, while the City of Eau Claire
is located south and west of the Site.
The Site is relatively flat and abuts a sandstone ridge to the south. The areas north and west are also
relatively level, generally sloping gradually toward the Chippewa River which is located
approximately 2 miles north and west of the Site. Lake Hallie lies approximately 1 mile north of the
Site and is an impounded remnant of a former channel of the Chippewa River.
Extending southward from Lake Hallie through the northwestern portion of the Site and westerly to
the Chippewa River is a buried pre-glacial valley that serves as a primary drinking water aquifer in
the Eau Claire area. Many private wells immediately north of the Site are finished in sand and gravel
deposits within the buried valley. Approximately 2 miles west of the Site, the Eau Claire Municipal
Well Field ("ECMWF") draws from the same buried valley deposits. The well field serves
approximately 60,000 people.
Notable surface features at the Site include the main building, a number of smaller buildings, and
Lagoons Nos. 1,2, 3 and 4. Lagoon No. 1 is a former sand and gravel pit with an irregular shape
and is approximately 1.5 acres in size. Lagoons Nos. 2, 3 and 4 are approximately 14, 3.1 and 3.4
acres in size, respectively.
A 6-foot, chain link fence surrounds the western one third of the Site, including the main building
and Lagoon No. 1, while the remaining areas of the Site are surrounded by a 4-foot wire fence. A
security alarm system is currently in place to restrict access.
-------
H. SITE HISTORY AND ENFORCEMENT ACTIVITIES
A. Site History
The property which now comprises the NPI Site was originally owned by various farmers who
utilized the land for agriculture. After the United States government (War Assets Administration)
acquired the property, two government contractors manufactured radar tubes and ordnance chemicals
at the facility until 1945. NPI purchased the property from the federal government in 1947. The
company initially manufactured household appliances and outboard motors at the facility, then added
defense-related products in 1951. By 1954, NPI had dedicated the Site entirely to defense-related
manufacturing, primarily the production of metal parts for 105MM and 8-inch shells, under contract
with the Department of the Army ("DOA").
Between 1959 and 1965, NPI engaged in little to no active production at the Site. In 1966, the Site
again was activated; multi-shift production continued until the mid-1970s. Except for a 6-month
research and development contract in late 1983 and early 1984, production of the 8-inch shells
ceased in 1971. Production of the 105MM projectiles ceased in 1980.
From 1981 to 1993, National Defense Corporation ("NDC"), a wholly owned subsidiary of NPI,
entered into annual standby contracts with the DOA to maintain the Site in a high state of readiness.
These contracts provided for the storage and maintenance of the government-owned machinery and
equipment. These contracts were terminated in October 1993 and most of the equipment has since
been disassembled and sold.
The most environmentally significant waste stream generated from NPFs defense-related activities
was waste forge compound. In its pure form, forge compound comprised approximately equal parts
of graphite, asphalt and mineral oil. NPI used this mixture as a lubricant in the forging operation
of the production of 105MM shells. "Waste" forge compound contains metals and volatile organic
compounds ("VOCs"), primarily 1,1,1-trichloroethane ("TCA"), a solvent used for cleaning the
forge compound from the manufacturing equipment. The waste water discharged by NPI to Lagoon
No. 1 contained significant amounts of waste forge compound. Additionally, between 1966 and
1970, NPI landfilled waste forge compound in an area northeast of the main plant, generally referred
to as the "Melby Road Disposal Site." Finally, waste forge compound has also been discovered in
an area near the east property line of the Site. This area is generally identified as the "East Disposal
Site." The United States Environmental Protection Agency ("U.S. EPA") considers Lagoon No. 1
and the Melby Road Disposal Site to be the most significant sources of the TCA ground-water1
contamination attributable to the Site. Wastes located at the East Disposal Site are the source of the
trichloroethene ("TCE") ground-water contamination in Plume 5.
1 Standard U.S. EPA nomenclature defines the term "ground water" as a noun and the
term "ground-water" as an adjective.
-------
The four ground-water plumes associated with the Site are depicted in Figure 2 of this Record of
Decision ("ROD")- Plume 1-2, approximately 2.8 miles in length, originates at the southwest corner
of the NPI Site, extends west and terminates at the ECMWF. Plume 3, approximately 1 mile long,
originates at the Melby Road Disposal Site and extends north to Lake Hallie. Plume 4, also
approximately 1 mile long, is located north of the Site and overlaps with Plume 3 as the two migrate
to Lake Hallie. Plume 5, approximately 1 mile long, originates at the East Disposal Site and also
extends north to Lake Hallie.
B. Response Actions
A significant amount of cleanup work has already been conducted in connection with the NPI Site
and its predecessor, the ECMWF Superfund Site.
In May 1986, NPI entered into an agreement with U.S. EPA and the Wisconsin Department of
Natural Resources ("WDNR") to conduct the Remedial Investigation/Feasibility Study ("RI/FS")
at the Site. An Administrative Order by Consent became effective on July 8,1986. The purpose of
the RI was to identify sources of contamination and to characterize the contamination at the Site.
The RI was finalized on September 12, 1994. The Final RI includes a Baseline Risk Assessment
which was conducted to characterize the current and potential threat to public health and the
environment at the Site.
The final ROD for the ECMWF Site, which was issued prior to U.S. EPAfs identification of the NPI
Site as the source of VOC contamination in Plume 1-2, was issued on March 31, 1988. The
ECMWF ROD, with which WDNR concurred, provided for continued operation of a two-column
air stripper constructed as an initial remedial measure for the ECMWF Site. The air stripper
continues to operate effectively, and currently treats approximately 6 to 7 million gallons of water
daily. The air stripper is located at the end of the longest of the NPI ground-water contaminant
plumes. Approximately $4 million in Superfund monies were dedicated for the ECMWF RI/FS,
design and construction of the air stripper. In 1993, NPI reimbursed U.S. EPA for more than 95%
of those costs and accepted responsibility for funding operation and maintenance of the air stripper
until such time that U.S. EPA determines, consistent with this final ROD for the NPI Site, that
treatment of the municipal water supply is no longer necessary.
The final ROD for the ECMWF Site further provided for the extension of municipal water service
from the City of Eau Claire to private well users in the area affected by Plumes 1 and 2 (identified
as Plume 1-2 in later documents).2 During the implementation of this component of the ECMWF
2 The final boundaries of the affected area were determined according to the results of
extensive private and monitoring well sampling conducted between 1985 and 1989. NPI
conducted additional sampling in the same area during the NPI RI under the direction of U.S.
EPA and WDNR to fully define the nature and extent of private well contamination. U.S. EPA
worked closely with WDNRfs District Office in Eau Claire to integrate data generated during the
-------
ROD, it became apparent to U.S. EPA and WDNR that, because of the sensitive nature of providing
municipal services to unincorporated areas, this component of the selected remedy was likely to be
unimplementable for the buffer zone adjacent to (then-designated) Plume 2. U.S. EPA decided,
accordingly, to delay implementation of this aspect of the ECMWF ROD until a more thorough
study of the problem could be completed.
In the interim, on April 25,1989, U.S. EPA issued a Section 106 Unilateral Administrative Order
pursuant to which NPI implemented a temporary bottled water distribution program for all private
well users in the unincorporated areas affected by Plumes 3,4 and 5. The temporary bottled water
program cost an estimated $ 100,000.
Next, on August 1, 1990, U.S. EPA issued a ROD under the auspices of the NPI Site selecting a
permanent alternative drinking water supply for the area affected by ground-water Plumes 3,4 and
5. Pursuant to a Section 106 Unilateral Administrative Order issued in March of 1991 to NPI and
NDC, these companies funded the construction of the newly-created Hallie Sanitary District's water
supply system as well as the extension of the City of Eau Claire's (64the City") municipal water
service to those portions of the affected area that had annexed to the City. The first service
connections to the Hallie Sanitary District were completed in December, 1991 and, by the middle
of the following summer, the District was fully operational and servicing the affected area within
the Town of Hallie. City of Eau Claire hook-ups to those portions of the affected area which had
annexed to the City were also completed by fall 1991. Approximately $3.65 million has been spent
implementing the remedy selected in the August, 1990 interim action ROD. In addition to the
creation of the Hallie Sanitary District, local regulations and ordinances currently restrict the use of
private wells in both the City and the Town of Hallie. Both the City and the Town of Hallie prohibit
the potable use of private water in areas connected tolhe municipal supplies, and private wells must
be disconnected from indoor plumbing.
Approximately one year later (September, 1991), U.S. EPA issued a ROD for the selected interim
action for on-site contaminated ground water at the NPI Site. The response objective of this interim
action was to prevent the off-site movement of contaminant Plumes 1-2 and 3, and to prevent further
environmental degradation of the ground water. The selected remedy included installation of
ground-water extraction wells and treatment of the extracted water by two independent cascade
aeration units, with discharge of the treated ground water via the City of Eau Claire storm sewer
system for transport to the Chippewa River. WDNR concurred in the selected remedy for on-site
ground water, and determined that the selected cascade aeration remedy satisfied the Best Available
Technology requirements of the federal Clean Water Act and chapter NR 220 of the Wisconsin
Administrative Code. (See ROD, Interim Action Alternative Selection, 9/30/91, p. 32.)
On July 2, 1992, U.S. EPA issued NPI and NDC another Section 106 Unilateral Administrative
Order, which required these companies to construct or fund the construction of the on-site ground-
NPIRI with the historical database to ensure that the affected area encompassed private wells
contaminated or threatened by contamination from the NPI Site.
-------
water treatment cascade system selected in the September, 1991 interim action ROD. Such
construction activities were completed in February, 1994 and the ground-water treatment system
began operation in March, 1994. To date, approximately $1 million has been spent implementing
the 1991 ROD. Annual operation and maintenance costs for this treatment system are approximately
$50,000.
Finally, on October 14, 1993, U.S. EPA, NPI and NDC entered into an Administrative Order by
Consent for the performance of time-critical on-site removal activities. This Order, subsequently
modified on November 4, 1994, provides for: (1) time-critical excavation of the waste forge
compound from Lagoon No. 1 and the East Disposal Site; and (2) use of such wastes as a
supplemental fuel at a cement kiln approved under the Comprehensive Environmental Response,
Compensation and Liability Act of 1980,42 U.S.C. § 9601 si seq., as amended by the Superfund
Amendments and Reauthorization Act of 1986, Pub. L. No. 99-499, 100 Stat. 1613 (1986)
("CERCLA"). Non-time-critical components of the removal action include characterization,
evaluation, design and remediation of soils and soil gas, if any, remaining in Lagoon No. 1 after the
excavation is complete. The estimated cost of the work to be completed pursuant to the removal
action is $4.4 million. By the end of 1995, almost all of the waste forge compound materials had
been excavated from Lagoon No. 1 and the East Disposal Site. Final excavation and characterization
work will continue in Spring 1996.
The FS was finalized on September 19,1995. This FS provides a detailed analysis of alternatives
evaluated for the final remedial action for the NPI Site.
HI. HIGHLIGHTS OF COMMUNITY PARTICIPATION
*
The U.S. EPA released its Proposed Plan for the final remedy for the Site on September 20,1995,
and made it available for public review and comment. The Proposed Plan and supporting documents
have been made available at the information repositories at the U.S. EPA Region V offices, the
Chippewa Falls Public Library, and the Hallie Town Hall. U.S. EPA has been placing relevant
information in these repositories since 1987. The Proposed Plan was mailed to everyone on U.S.
EPA's mailing list, and press releases were sent to local media. Notice of the availability of the
Proposed Plan was also included in advertisements in the Eau Claire Leader Telegram and the
Chippewa Falls Herald in September 1995. Before reaching a final decision on how the Site
contamination would be addressed, U.S. EPA held a public meeting on September 27,1995 at the
Hallie Town Hall. At this meeting, representatives of U.S. EPA answered questions about the
proposed remedy and accepted formal comments from the public on the Proposed Plan and remedial
alternatives. U.S. EPA also accepted written comments during the comment period, which ran from
September 20, to October 20, 1995. A response to all comments received during the public
comment period is contained in the Responsiveness Summary, which is attached to this ROD.
-------
IV. SCOPE AND ROLE OF RESPONSE ACTION WITHIN SITE STRATEGY
As with many Superfund sites, the problems at the NPI Site are complex. As noted above, early site
characterization activities conducted as part of the RI identified contaminated drinking water
supplies that could be addressed before fiill characterization activities were complete. Therefore,
to accelerate site remediation, U.S. EPA, in consultation with WDNR, organized the work into three
operable units ("OUs") and a removal action. These are as follows:
Alternate drinking water supply (OU #1): A permanent replacement drinking water supply
for the areas affected by the contaminated ground water.
Interim Action (OU #2): Containment and treatment of on-site ground water at the Melby
Road Disposal Site and the southwestern portion of the Site downgradient of Lagoon No. 1
and Ditch No. 3.
Final Remedy (OU #3): Final remediation of the on-site source areas including the Melby
Road Disposal Site, the East Disposal Site, Ditch No. 3, and Dry Wells 2 and 5. Continued
remediation of the plumes emanating from the Site.
Removal Action: Time-critical removal of liquid and solid waste forge compound at Lagoon
No. 1 and the use of such wastes as a supplemental fuel at a cement kiln. The 1993
Administrative Order by Consent, subsequently modified in 1994, also provides for non-
time-critical removal actions including the characterization, evaluation, design, and final
remediation of remaining soils and soil gas, if any, in the vadose zone at Lagoon No. 1. All
reports generated as a part of these actions wijl be included in the Administrative Record for
this Site.
This ROD addresses the final remedy for the Site. The remaining threats posed by this Site to
human health and the environment are primarily associated with the contaminated soils at the Site.
This action will address all remaining on-site source areas including the Melby Road Disposal Site,
the East Disposal Site, Ditch No. 3 and Dry Wells 2 and 5 (see Figure 3). Since previous remedial
actions have already addressed threats to human health and the environment posed by contaminated
ground water, this action will address the continued cleanup of contaminated ground water in Plumes
1-2, 3,4 and 5.
V. SUMMARY OF SITE CHARACTERISTICS
A. Geology and Hydrogeology
The Site is located hear the edge of the glacial outwash terrace and part of the property lies on the
flanking ridge. Surficial deposits of glacial outwash (sand and gravel) overlie the Mount Simon
Formation (sandstone) of Cambrian Age except along the southeastern portion of the property where
-------
the sandstone ridge is exposed and in the buried valley where the sandstone has been removed by
erosion. The Mount Simon Formation is underlain by Precambrian rocks, usually granite.
At the eastern and extreme southern portions of the Site, where ground water occurs primarily in the
sandstone bedrock, the ground water generally flows to the northwest. At the northwestern portion
of the Site, where ground water occurs in alluvial deposits overlying bedrock, ground-water flow is
more complex due to the existence of a buried valley and a water table divide. The water table
divide extends in a northwestern direction from the northwest corner of the Site. South of the divide,
ground water flows westward into the buried valley to the ECMWF and the Chippewa River. North
of the divide, ground water flows north and discharges at Lake Hallie.
B. Nature and Extent of Contamination
The RI investigation included numerous sampling and investigative activities since late 1986. Work
conducted during the RI included sampling and analysis of ground water, soils, soil vapor and waste
materials, and geologic and hydrogeologic studies.
The RI identified VOCs, including TCA, TCE, tetrachloroethene ("PCE") and their degradation
products, 1,1-dichloroethane ("1,1-DCA"), 1,1-dichloroethylene ("1,1-DCE"), and 1,2-
dichloroethylene ("1,2-DCE") in waste forge compound, waste forge compound/soil mixtures, soil,
other wastes, and ground water at the NPI Site. Semi-volatile organic compounds ("SVOCs") and
trace metals were also detected in these media. However, SVOCs were not detected in ground water
from monitoring wells at or downgradient of the areas of concern. Forge compound in its virgin
state is composed of approximately one-third asphalt, which contains polyaromatic hydrocarbons
("PAHs"), a class of SVOCs.
Source Areas
Waste forge compound/soil, other wastes, and soil containing contaminants of concern were found
at the following areas: Lagoon No. 1, the Melby Road Disposal Site, the East Disposal Site,
Drainage Ditch 3, and Dry Wells 2 and 5. The RI report contains analytical data for these areas. It
is possible, although not likely, that unidentified source areas exist at the NPI Site, given its 320-acre
size and long, complex operational history. U.S. EPA has investigated, however, all available
records of the Site, including aerial photographs taken at the height of NPI defense-related
operations.
The RI source characterization revealed the presence of VOCs, SVOCs, and/or metals at the areas
of concern. The most commonly found VOCs were TCA, TCE and 1,1-DCA. Polychlorinated
biphenyls ("PCBs") were detected in Dry Wells 2 and 5 and in two samples of drummed waste from
the East Disposal Site. Characterization of the waste forge compound in Lagoon No. 1 revealed the
presence of a number of SVOCs including phenanthrene, anthracene, fluoranthene, pyrene, and
chrysene.
-------
Lagoon No. 1
Remediation of the Lagoon No. 1 area was addressed by the October 1993 Administrative Order by
Consent and the October 1994 Modification issued by U.S. EPA. The Lagoon No. 1 pumpable
waste forge compound was removed, fuel blended and burned as a supplemental fuel in a cement
kiln. The waste forge compound solids remaining in the lagoon are currently being removed,
packaged, and used as a supplemental solid cement kiln fuel. Standing water has been removed as
waste forge compound solids removal occurs. The vadose zone beneath Lagoon No. 1 will be
characterized and remedial alternatives such as SVE will be evaluated and implemented, if
necessary, based on the characterization results.
The analytical results presented in the RI indicate that the Lagoon No. 1 waste forge compound
contained VOCs, primarily TCA (up to 110,000 |ig/kg) and its decomposition product 1,1-DC A (up
to 3,800 |ig/kg)), and metals, with zinc being present at the highest concentration (6,950 mg/kg).
PCE was also detected in one sample at 3,600 ng/kg. Tentatively Identified Compounds ("TICs")
consisted primarily of hydrocarbons (nonane, decane, undecane, and dodecane). Toxicity
Characteristics Leaching Procedure ("TCLP") analyses for VOCs, SVOCs and metals were
performed on Lagoon No. 1 waste forge compound samples and all results were well below the
regulatory thresholds for toxicity set forth at 40 CFR 261. The waste forge compound/soil mixture
in the lagoon is expected to contain the same types of contaminants as were found in the Lagoon No.
1 waste forge compound.
Samples of waste forge compound and condensate were collected for SVOC and VOC analyses
during the 1992 sludge drying study described in the "Waste Forge Compound Treatability Studies
Summary Report" (Eder, August 1992). These analytical results are also presented in the RI.
SVOCs detected in the raw (undried) waste forge compound samples include naphthalene (19,000
Hg/kg), phenanthrene (83,000 ^g/kg), anthracene (14,000 ng/kg), fluoranthene (20,000 jig/kg),
pyrene (32,000 ^tg/kg) and chrysene (29,000 ^ig/kg). The SVOC concentrations detected in the
dewatered samples were generally 20 to 40 percent higher than the concentrations in the raw
samples. Phenol (9,000 jig/L), benzyl alcohol (5,600 ng/L), 4-methyl phenol (2,800 ^g/L),
naphthalene (3,400 ^ig/L), isophorone (32,000 |ig/L), phenanthrene (500 |ig/L) and 2-methyl
naphthalene (3,400 |ig/L) were detected in the condensate samples collected during the test runs.
VOC analyses from the drying study yielded results similar to previous analyses of Lagoon No. 1
waste forge compound samples. The ability to achieve lower detection limits for the condensate
samples showed the presence of additional VOCs not previously detected in the waste forge
compound.
Lagoon No. 1 standing'water samples contained 1,1 DCA (3 ^ig/L), 1,2 DCE (0.2 jig/L), and
inorganics, including nickel (46 |ig/L) and zinc (98
-------
Melbv Road Disposal Site
Waste forge compound was disposed of at the Melby Road Disposal Site from 1966 to 1970 in
trenches and apparently by spreading and mixing with soil. During the RI, waste forge compound
was found mixed with soil over most of the Melby Road Disposal Site. The RI estimated
approximately 53,000 cubic yards ("cy") of soil/waste material in this area. The laboratory
analytical results for the test pit and soil boring samples collected in August 1993 were qualified as
estimated values because the samples were analyzed outside the recommended technical holding
time (within 14 days of sample collection). The highest VOC levels in waste, soil, and soil vapor
samples were detected in the central part of the disposal area. TCA was the primary VOC detected,
at concentrations ranging from 100 to 880,000 ^ig/kg, with lower concentrations of TCE, PCE, 1,1-
DCA, benzene, toluene, ethyl benzene, and xylenes also present. The materials found in this area
include: thin seams of waste forge compound mixed with small amounts of soil; drums containing
waste forge compound; and waste forge compound/soil mixture extending to approximately 23 feet
below grade. The TCA concentrations in ashy wastes found to a depth of 22 feet at the north-central
part of the disposal area were lower (<11 |ig/kg), with PCE at 16 ng/kg and total xylenes at 85
|ig/kg. The waste forge compound/soil mixtures at the eastern and western portion of the Melby
Road Disposal Site were characterized by relatively consistent thicknesses and lower VOC
concentrations in the waste and underlying soil.
VOCs either were not detected or were found at low concentrations in samples of the cover material
and the native soil beneath the waste at the Melby Road Disposal Site. Portable gas chromatograph
screening detected PCE at concentrations ranging from 0.1 to 28.4 ppb in samples collected from
the surface down to the water table in three of the 14 borings drilled in August 1993. The VOC
concentrations in the soil samples collected from on$ boring drilled at the central part of the waste
disposal area decrease until non-detectable levels are reached 15 to 20 feet below the waste. Portable
gas chromatograph screening for three other borings did not detect TCA in soil immediately below
the waste, but TCA was detected in samples from depths up to 60 feet below grade. At most other
locations, VOCs other than PCE were not detected in soil samples collected more than two feet
below the bottom of the waste. Complete analytical results are presented in the RI report.
Fifteen partially crushed drums were removed from the Melby Road Disposal Site during the August
1993 investigation and separated from the other excavated materials. The drums were open-ended
and contained waste forge compound. Some of the drums were sheared by the excavator. The
drums were overpacked and stored under an overhang on the steel loading dock of Building 102 at
the NPI Site. Much of the waste in these drums has been used as a supplemental cement kiln fuel
as part of the ongoing Lagoon No. 1 waste forge compound solids removal activity. Any drummed
waste that is not a suitable fuel source will be disposed of at an appropriate off-site facility. The
empty drums have been steam cleaned and hauled to a scrap metal dealer for recycling.
-------
East Disposal Site
Remediation of the waste forge compound solids in the East Disposal Site trench is addressed by the
Modification to the October 1993 Administrative Order by Consent Remaining soil/waste materials
are estimated to be approximately 1,300 cy. Residual contamination beneath the soil/waste material
will be characterized after removal of overlying waste. The need for soil remediation will be
evaluated during the implementation phase of the project. The chemical characterization of these
materials is described below.
Samples of the waste forge compound/soil mixture from the East Disposal Site trench contained
TCE (up to 6,100 ^g), PCE (up to 6,800 ^g/kg), TCA (up to 140,000 ^g/kg) and hydrocarbons
(benzene, toluene, ethyl benzene, and xylenes). Other wastes found at the East Disposal Site consist
of construction debris (metal, wood, glass, and concrete); a white powdery material mixed with a
black ash-like material; and a red granular material. VOCs including TCE (up to 81,000 |ig/kg),
TCA (up to 1,500 |ig/kg) and PCE (up to 28 |ig/kg) were detected in the surficial wastes remaining
at this location. PCBs (up to 39 |ig/kg) were also detected in one sample at 0-2 feet. A soil vapor
survey was conducted in 1989 and the TCE soil vapor concentration contours were used to select
additional sampling locations. TCE (up to 1,200 ^ig/kg), TCA (up to 110 ng/kg), and 1,2-DCE (up
to 15 fig/kg) were detected in soil samples from the unsaturated zone. VOC concentrations decrease
with depth in the sand and gravel which underlie the wastes. Selected waste samples from the East
Disposal Site were subjected to TCLP analysis during the RI. The leachable VOC concentrations
were less than the U.S. EPA Toxicity Characteristics ("TC") regulatory levels established in 40 CFR
261. Complete analytical data are presented in the RI report.
Twenty-four drums containing solid wastes were removed from the East Disposal Site in July 1986
and stored under an overhang on the steel loading dock of Building 102 at the NPI Site. The
contents of four representative drums (numbers 2,4,5, and 16) were sampled and analyzed in 1987.
Drum 4 contained the only detectable concentrations of VOCs, with TCE at 4 jig/kg and 1,1,2,2-
tetrachloroethane at 13 ^g/kg. The SVOC analysis revealed the presence of PAHs in drum 4 and
PCBs in drums 2 and 16, respectively. Elevated concentrations of arsenic, barium, chromium, lead,
nickel, and zinc were also found in the four drums that were sampled. Much of the waste in these
drums has been used as supplemental cement kiln fuel as part of the ongoing Lagoon No. 1 waste
forge compound solids removal activity. Any drummed waste that is not a suitable fuel source will
be disposed of at an appropriate off-site facility. The empty drums have been steam cleaned and
hauled to a scrap metal dealer for recycling.
Drainage Ditch 3
Drainage ditches were installed at the NPI Site before 1947 to convey storm water and wastewater
from buildings. TCA (up to 48,000 ^g/kg), toluene (up to 2,800 ng/kg), and 1,1-DCA (up to 11,000
Hg/kg) were detected in the waste forge compound/soil mixture in Drainage Ditch 3. The RI
estimated approximately 3,000 cy of waste forge compound/soil mixture in Drainage Ditch 3. The
metals concentrations detected were generally above background levels for the NPI Site. Chromium,
10
-------
copper, nickel, and zinc were found in the highest concentrations, in the range of 100 to 500 mg/kg,
as compared to background concentrations of about 2 to 10 mg/kg for these metals. Complete
analytical data are presented in the RI report.
Drv Wells 2 and 5
Waste streams and storm water were discharged to six dry wells at the NPI Site. The RI estimated
approximately 50 cy of contaminated soil and sediment in these dry wells. Contaminants detected
in soil adjacent to the bottom of Dry Well 2 include TCA (38 ng/kg), 1,1-DCE (13 ng/kg), and PCBs
(960 ^ig/kg). Contaminants in sediment at the bottom of Dry Well 5 include PAHs (phenanthrene
and fluoranthene at 79,000 and 89,000 ng/kg, respectively) and PCBs (14,000 ^g/kg). The adjacent
soil and bottom sediment samples from these dry wells contained metals at concentrations above
background levels for the NPI Site. Chromium (192 mg/kg), lead (32 mg/kg), and zinc (311 mg/kg)
were detected in a soil sample adjacent to Dry Well 2, compared to Site background concentrations
up to 7.1 mg/kg, 12.6 mg/kg, and 9.3 mg/kg, respectively. The bottom sediment from Dry Well 5
also contained chromium (25 mg/kg), lead (21 mg/kg), and zinc (278 mg/kg) at concentrations above
Site background, as well as copper (483 mg/kg compared to a Site background concentration of 10.4
mg/kg). Complete analytical data are presented in the RI report.
Ground Water
The RI determined that ground-water contamination from the NPI Site is characterized primarily by
VOCs. On-site ground water also contains metals (barium, cadmium, chromium, copper, lead,
nickel, and zinc) at concentrations above background levels, with concentrations at all but one
location below state and federal ground water quality standards. On-site monitoring well MW-10A,
located downgradient of Lagoon No. 1, contained cadmium at levels (8 to 36.2 |ag/L) higher than
the federal Maximum Contaminant Level ("MCL") (5 |ig/L), the Wisconsin Enforcement Standard
("ES") (5 yg/L), and the Wisconsin Preventive Action Limit ("PAL") (0.5 ^ig/L) for ground water.
Wisconsin and federal standards for metals are not exceeded at the off-site monitoring wells.
Ground water VOC contamination at and around the NPI Site occurs in four distinct plumes,
identified as Plumes 1-2, 3,4 and 5, as shown on Figure 2. These plumes have been defined and
characterized, with each plume delineated by a minimum concentration of 1 ng/L total VOCs. The
boundaries of the plumes are defined by the network of monitoring wells installed during the RI.
Section 4.0 of the RI report contains the data used to characterize ground water contamination.
11
-------
Plume 1-2
Plume 1-2 is characterized by the occurrence of TCE, TCA, and 1,1 -DCE. However, MCLs were
only exceeded for TCE (MCL = 5 ng/L).3 The highest off-site concentration of TCE in Plume 1-2
was 18 ^g/L. TCA and 1,1-DCE concentrations were all below MCLs of 200 ^ig/L and 7
respectively. The highest off-site concentrations of TCA and 1,1-DCE were 100 ^ig/L and 4
respectively. The plume extends from the southwestern portion of the NPI Site to the ECMWF,
having a maximum width of approximately 1,700 feet and a length of 15,000 feet (measured along
its axis). As discussed earlier, a two-column air stripper was placed in service in August 1987 to treat
contaminated ground water at the ECMWF prior to its introduction into the City of Eau Claire's
water treatment and distribution system. This stripper continues to treat contaminated ground water
extracted at the leading edge of Plume 1-2. Monitoring wells were installed during the RI to track
ground water in Plume 1-2 along its path from the NPI Site to the ECMWF.
Plumes 3. 4 and 5
Plume 3 contains TCA, 1,1-DCE, and PCE, and extends approximately 9,000 feet from the Melby
Road Disposal Site to Lake Hallie to the north, having a maximum width of 1,500 feet. Off-site
concentrations of TCA, 1,1-DCE, and PCE do not exceed MCLs. Plume 4 is entirely off-site,
overlaps a portion of Plume 3 north of the NPI Site and is characterized primarily by TCE. MCLs
were only exceeded for TCE. The highest concentration of TCE found in Plume 4 was 14 |ig/L.
Plume 5 also consists primarily of TCE and extends approximately 6,500 feet from the East Disposal
Site to Lake Hallie, having a maximum width of approximately 1,000 feet. No MCLs are exceeded
in Plume 5; however, the MCL of 5 ^ig/L for TCE is attained. Ground water in Plumes 3,4, and 5
discharges to Lake Hallie. Surface-water samples taken during the RI showed maximum TCA and
TCE concentrations of 1 (ig/L and 3 |ig/L, respectively. The concentrations of TCA and TCE found
in the surface-water samples were well below U.S. EPA's ambient water quality criterion and
Wisconsin's surface water quality standards.
VI. SUMMARY OF SITE RISKS
CERCLA requires that U.S. EPA protect human health and the environment from current and
potential exposure to releases of hazardous substances at or from the Site. As part of the RI, a
Baseline Risk Assessment is required to assess the current and potential future risks by the Site. The
Baseline Risk Assessment determines whether contamination at the Site could pose an unacceptable
health risk or environmental risk in the absence of any remedial action. Potential threats to public
health are estimated by making assumptions about the manner, frequency and length of time a person
could be exposed to site-related contaminants.
3MCLs are numerically equivalent to ESs, so all references to MCL exceedances in this
ROD also indicate an ES exceedance.
12
-------
The Baseline Risk Assessment (Western, July 1993) evaluated current and future potential human
health or environmental risks associated with the NPI Site. The qualitative risk assessment
examined contaminants detected in ground water and soils during the field investigation phase of
the RI. These contaminants were evaluated with respect to their carcinogenicity, toxicity, and
possible exposure pathways from and at the Site.
All chemicals identified in all Site media were evaluated: soil, ground water, surface water,
sediments, and waste materials. Each sample was assessed by evaluating data qualifiers and blank
sample concentrations. Upon screening each sample, the following list of chemicals of potential
concern was developed:
Volatile Organic Compounds
Acetone
Methylene Chloride
1,1-Dichloroethene
1,1-Dichloroethane
1,2-Dichloroethene (total)
2-Butanone
1,1,1 -Trichloroethane
Trichloroethene
Benzene
Tetrachloroethene
Toluene
Ethyl benzene
Xylenes (total)
Semi-volatile Organic Compounds
1,2-Dichlorobenzene
Naphthalene
2-Methyl naphthalene
Acenaphthylene
Acenaphthene
Dibenzofuran
Fluorene
Phenanthrene
Anthracene
Fluoranthene
Pyrene
Benzo(a)anthracene
Chrysene
Benzo(b)fluoranthene
Benzo(a)pyrene
Inorganics
Aluminum
Antimony
Arsenic
Barium
Cadmium
Calcium
Chromium
Copper
Iron
Lead
Magnesium
Manganese
Nickel
Potassium
Selenium
Silver
Sodium
Vanadium
Zinc
VOCs and/or inorganic compounds were detected in samples of soil, waste material, and ground
water. VOCs were detected in surface water samples. SVOCs (PAH compounds) were detected in
the Lagoon No. 1 waste forge compound.
The exposure assessment described site-specific characteristics prior to any cleanup activity at the
Site, including: soils, geology, surface water, ground water, climate, demographics, and land and
water use. The on-site and off-site potentially exposed populations were identified. Each of the
chemicals of potential concern was evaluated in terms of its fate and transport properties. This
evaluation identified the environmental compartment (i.e. air, water or soil) to which each chemical
would tend to migrate.
13
-------
The following exposure scenarios were identified and evaluated in the Baseline Risk Assessment:
Current Off-Site Residents (Adult and Child^
Ingestionofsoil
Dermal Absorption of soil
Inhalation of dust
Future On-Site Residents (Adult and Child^
Ingestion of soil and ground water
Dermal Absorption of ground water
Inhalation of vapors from ground water
Current Off-Site Recreational (Adult and Child]
Ingestion of water while swimming
Dermal Absorption of water while swimming
Consumption of recreationally caught fish
Current On-Site Worker
Ingestionofsoil
Dermal Absorption of soil
Inhalation of dust
The available health effects criteria for each chemical of potential concern were identified. Known
or suspected carcinogens and non-carcinogens were addressed independently.
The risk characterization integrates the exposure and toxicity assessments into a measurable
expression of risk for each exposure scenario. The cancer risk is expressed as a probability of a
person developing cancer over the course of his or her lifetime. According to the National
Contingency Plan ("NCP"), a cancer risk of 1 .OE-06, which represents one additional occurrence of
cancer in one million people, is considered a reference level for evaluating acceptable risk.
The non-carcinogenic risk is presented as a hazard index. A hazard index greater than one indicates
that there may be a concern for potential health effects resulting from exposure to non carcinogens.
The total carcinogenic and non-carcinogenic risks calculated for each receptor and exposure pathway
evaluated in the Baseline Risk Assessment are presented in Table 1.
The carcinogenic risk and non-carcinogenic hazard to current off-site residents (adult and child) from
exposure to off-site soil were calculated. The total non-carcinogenic hazard indices for an adult
ranged from 9.7E-03 to 1.4E-02. The total non-carcinogenic hazard indices for a child ranged from
14
-------
8.9E-02 to 1.3E-01. The Baseline Risk Assessment indicates that adverse non-carcinogenic health
effects are not expected under this exposure scenario. The adult and child exposure scenario risks
were calculated; the total excess cancer risk ranged from 8.4E-07 to 3.7E-06. A large portion of the
total cancer risk was attributed to ingestion of arsenic in the soil. The Baseline Risk Assessment
reports that the risk associated with this pathway is likely overestimated by one to two orders of
magnitude due to the uncertainty associated with the toxicological data available for arsenic.
The potential future cancer risk and hazard was evaluated for on-site residents (adult and a child)
due to exposure to on-site soil and ground water. The Baseline Risk Assessment indicates that the
calculated carcinogenic and non-carcinogenic health threats are potentially significant under this
scenario. The non-carcinogenic hazard indices for an adult ranged from 1.2 to 2.6. The hazard
indices for a child range from 3.4 to 6.6. The majority of this health risk (>85%) was associated with
exposure to the ground water. For the ground water exposure pathway, the majority of the
noncarcinogenic risk was attributed to the ingestion of antimony and arsenic in the drinking water.
Although the majority of the risk was due to ingestion of arsenic in drinking water, the risks
associated with exposure to several VOCs (1,1-DCE, TCE and PCE) also exceeded l.OE-06. The
total cancer risk (i.e., for soil and ground-water exposure combined) ranged from 6.0E-05 to 3.8E-04.
The majority of the cancer risk is associated with exposure to on-site soils, of which more than 99%
of the risk is due to exposure to carcinogenic PAHs. It is noteworthy that the Baseline Risk
Assessment states that this future residential exposure scenario is unlikely, and that the methods used
to determine the associated health risks were conservative.
For current recreational exposure to contaminants in Lake Hallie, both carcinogenic and non-
carcinogenic health risks were found to be insignificant.
*
The current risk and hazard to workers at the NPI Site due to exposure to chemicals of potential
concern were calculated. The Baseline Risk Assessment indicates that the health risks posed by
worker exposure to non-carcinogens at the NPI Site were insignificant. The total excess cancer risk
for workers ranged from 4.4E-06 to 5.4E-05. The major contributors to the risk are PAHs. The
Baseline Risk Assessment states that conservative methods were used to determine the associated
health risks and that actual risks are expected to be less than the calculated values.
Based on the qualitative analyses, the ecological risks associated with exposure of the terrestrial,
aquatic and avian species to contaminants at the NPI Site are within a range acceptable under U.S.
EPA guidance and regulations.
The primary risks remaining at the NPI Site relate to the potential for the continued contamination
of ground water. In order to provide for the long term protection and cleanup of the ground water,
source control measures must be implemented. Even though the interim action pump and treat
systems currently prevent the off-site migration of contaminated ground water, source areas at the
NPI Site must be contained or eliminated in order to facilitate the long-term cleanup of the aquifer.

VH. DESCRIPTION OF ALTERNATIVES
The alternatives evaluated in the FS are consistent with the previous cleanup phases already
undertaken at the NPI Site. Prior actions at the Site include: the installation of a two-column air
stripper at the ECMWF; the extension of municipal water service from the City of Eau Claire to
private well users in areas affected by Plume 1-2; installation of permanent alternate drinking water
supplies for areas of private well contamination near the NPI Site; and installation of the on-site
ground-water interim remedial action. The interim remedial action consists of continuous ground-
water extraction at the Melby Road Disposal Site and the southwestern portion of the NPI Site with
treatment and discharge of the extracted ground water to the Chippewa River via the City of Eau
Claire storm sewer system.
The FS identified and evaluated cleanup alternatives that could be used to address threats and/or
potential threats posed by the NPI Site. The alternatives were divided into source control
alternatives and ground-water cleanup alternatives. The source control alternatives were designed
to reduce or eliminate direct contact human health risks and prevent additional ground-water
contamination. An overall source control remedy for the NPI Site combines several alternatives,
each applicable to a specific area and material type. The ground-water cleanup alternatives were
designed to address the existing ground-water contamination at the four plumes of VOCs to attain
the long-term goal of reducing the VOC concentrations to PALs. The following section briefly
describes the alternatives considered by U.S. EPA in the process of determining a final cleanup
remedy for the NPI Site. The alternatives U.S. EPA has selected as part of the final remedy are
highlighted with a large asterisk.
SOURCE CONTROL ALTERNATIVES
^HIT -TT ^f irrrTTrwimiwrmf T tinirn iTir-r ^
Alternatives have been developed to address the four sources areas: Melby Road and East Disposal
Sites, Drainage Ditch 3 and Dry Wells 2 and 5.
MELBY ROAD and EAST DISPOSAL SITES
The alternatives evaluated for addressing the contaminated soils at the Melby Road and East
Disposal Sites are:
Alternative M-A - No Action
Capital Cost: $0
Annual Operation and Maintenance (O&M) Cost: $0
Present Worth (30 Year): $0
Estimated Construction Time Frame: None
The inclusion of the No-Action alternative is required by law to give U.S. EPA a basis for
comparison. Under the No-Action alternative, source control measures at the Melby Road and East
16
-------
Disposal Sites would not be implemented. This alternative would not effectively reduce threats to
human health and the environment posed by the Melby Road and East Disposal Sites.
JL
Alternative M-B1 - Soil Vapor Extraction, Hotspot Removal at Melby Road, Excavation and
Consolidation of East Disposal Site Wastes and Multi-Layer Cap over Combined Wastes at the
Melby Road Disposal Site
Capital Cost: $2,890,000
Annual O&M Cost: $78,500
Present Worth (30 Year) Cost: $3,900,000
Estimated Construction Time Frame: two years
This alternative consists of installing a soil vapor extraction ("SVE") system at the Melby Road
Disposal Site; removing areas of concentrated waste materials ("hotspots"), if any, identified by the
SVE system; excavating approximately 1,300 cy of waste forge compound mixed with soil identified
at the East Disposal Site; combining these wastes with the wastes at the Melby Road Disposal Site;
and, finally, installing a multi-layer cap compliant with Wisconsin Administrative Code Chapter NR
660 over all of the waste materials.
The SVE system would be installed and monitored before the installation of the cap in order to
identify the location of possible hotspots at the Melby Road Disposal Site. These concentrated waste
materials would be excavated and disposed of in an off-site disposal facility. This hotspot removal
approach would reduce the possibility that future waste removal would be required after the cap is
installed. The objective of the SVE system would be to prevent future releases of VOCs into the
ground water. A soil gas monitoring program would be implemented to monitor the effectiveness
of the SVE system in removing VOCs.
A multi-layer cap compliant with NR 660 would eliminate the potential for direct human contact
with wastes and would reduce leachate generation at the NPI Site. A typical cap consists of a
synthetic, plastic membrane over a 2-foot-thick soil layer, a 1-foot-thick sand drainage layer, and an
approximate 2-foot-thick topsoil layer. The topsoil layer would be seeded so that it would eventually
be covered with grass. A ground-water monitoring program would be implemented upgradient and
downgradient of the capped areas to monitor the effectiveness of the caps in reducing contaminant
migration to ground water. The effectiveness of the cap would be tracked via a long-term ground-
water monitoring system. U.S. EPA would seek deed restrictions limiting land use in the future
development of the capped area.
Alternative M-B2 - Soil Vapor Extraction, Hotspot Removal at Melby Road and Multi-Layer Cap
over contaminated soils at each of the Melby Road and East Disposal Sites
Capital Cost: $3,040,000
Annual O&M Cost: $130,000
17
-------
Present Worth (30 Year) Cost: $4,700,000
Estimated Construction Time Frame: two years
This alternative is similar to Alternative M-B1 except that the waste forge compound soil mixture
at the East Disposal Site would not be excavated and combined with the waste materials at Melby
Road. Instead, a separate SVE system and multi-layer cap compliant with MR 660 would be
installed at the East Disposal Site in addition to the SVE system and multi-layer cap at the Melby
Road Disposal Site.
Alternative M-C1 - Partial Source Removal from Melby Road to On-Site Landfill, Multi-Layer Cap
over remaining contaminated soils with Soil Vapor Extraction at the Melby Road and East Disposal
Sites
Capital Cost: $5,150,000
Annual O&M Cost: $ 130,000
Present Worth (30 Year) Cost: $7,040,000
Estimated Construction Time Frame: two years
Under a partial removal at the Melby Road Disposal Site, all visibly impacted waste materials within
the area defined by the RI soil vapor survey, approximately 14,000 cy, would be removed and
disposed of in an on-site hazardous waste landfill compliant with NR 660 requirements. As
described in Alternative M-B2, SVE systems and multi-layer caps would be installed at the Melby
Road and East Disposal Sites to cover wastes that remain in place.
Alternative M-C2 - Partial Source Removal from Melby Road to Off-Site Landfill Multi-Layer Cap
over remaining contaminated soils with Soil Vapor Extraction at the Melby Road and East Disposal
Sites
Capital Cost: $8,300,000

Present Worth (30 Year) Cost: $9,950,000
Estimated Construction Time Frame: 15 months
This alternative is the same as Alternative M-C1 except that the visibly impacted waste materials
at the Melby Road Disposal Site would be disposed of in an off-site hazardous waste landfill. As
described in Alternative M-C1, wastes that remain in place under the partial removal scenario would
be capped and an SVE system would be installed at the Melby Road and East Disposal Sites.
Alternative M-D1 - Source Removal to On-Site Landfill
Capital Cost: $7,600,000
Annual O&M Cost: $71,500
18
-------
Present Worth (30 Year) Cost: $8,500,000
Estimated Construction Time Frame: two years
This alternative consists of excavating approximately 53,000 cy and 1,300 cy of waste forge
compound mixed with soil from the Melby Road and East Disposal Sites, respectively, and
disposing of these wastes in a single on-site hazardous waste landfill compliant with NR 660
requirements. The waste forge compound may need treatment (solidification)4 prior to disposal.
Construction debris would be separated from the waste forge compound and would be disposed of
in an on-site landfill or at a licensed construction and demolition landfill. Under this source removal
alternative, all visibly contaminated waste materials would be excavated and disposed of in an on-
site hazardous waste landfill. The FS assumed that the landfill could be constructed at Lagoon No.
2; the actual landfill location would be selected during the upcoming design phase. The landfill
would be constructed according to federal and state hazardous waste requirements. A ground-water
monitoring program would be implemented to track water quality upgradient and downgradient of
the landfill. Post excavation samples will be collected to determine if any contamination remains
in the soil that will require cleanup. U.S. EPA would seek deed restrictions limiting land use in the
future development of the on-site landfill.
Contamination remaining in the soil after removal of overlying waste would be evaluated based on
post-excavation sampling results. Additional cleanup such as an SVE system will be installed if any
remaining contamination would cause ground-water standards to be exceeded.
Alternative M-D2 - Source Removal to Off-Site Landfill
Capital Cost: * $21,500,000
Annual O&M Cost: $0
Present Worth (30 Year) Cost: $21,500,000
Estimated Construction Time Frame: one year

at the Melby Road and East Disposal Sites would be disposed of in an off-site hazardous waste
landfill.
Alternative M-E - Source Removal with On-Site Low Temperature Thermal Desorption; and On-
Site or Off-Site Disposal of Treated Materials
Capital Cost: $23,870,000 to $37,790,000

these materials in a low-temperature thermal desorption ("LTTD") system at the NPI Site, then
disposing of the treated waste materials in an on-site or off-site hazardous waste landfill compliant
with NR 660. An LTTD system removes VOCs from waste materials by heating them in a large
rotary dryer.
Alternative M-F - Source Removal with On-Site Incineration; and On-Site or Off-Site Disposal of
Residual Ash

mixed with soil from the Melby Road and East Disposal Sites, respectively, incinerating waste
materials in an on-site treatment unit to destroy organic contaminants and disposing of the ash in an
on-site or off-site, solid or hazardous waste landfill, based on testing results. The location of the
incineration unit would be determined when the cleanup project is designed. Additional treatment
(solidification) may be required to immobilize inorganic compounds before the ash could be
disposed of in an on-site or off-site landfill.

Annual O&M Cost: $0
Present Worth (30 Year) Cost: $41,000
Estimated Construction Time Frame: three months
22
-------
This alternative consists of excavating approximately 50 cy of contaminated soils and sediments at
Dry Wells 2 and 5, treating these materials (if necessary), and disposing of these wastes in an off-site
hazardous waste landfill. Based on the concentrations of PCBs detected in these materials during
the RI, these wastes would need to be disposed of at a facility licensed to accept PCB-contaminated
wastes. Disposal at the on-site landfill is not feasible because of the type of contaminants (including
PCBs and metals) detected in these materials.
GROUND-WATER CLEANUP ALTERNATIVES
Alternatives have been developed to address the four VOC plumes attributed to sources at the NPI
Site. These plumes are identified as Plumes 1-2, 3, 4, and 5. U.S. EPA has determined that the
effectiveness of the ground-water alternatives at the NPI Site depends largely on source control.
Therefore, each ground-water alternative assumes that source control measures are being
implemented at the NPI Site and the on-site ground-water interim action (cascade aeration) continues
to effectively prevent off-site migration of contaminated ground water from the Melby Road
Disposal Site and the Lagoon No. 1 - Drainage Ditch 3 Area. Each ground-water alternative further
assumes continued operation of the ECMWF air stripper until such time that ground-water
Applicable or Relevant and Appropriate Requirements ("ARARs") are achieved.
PLUME 1-2
The alternatives evaluated for addressing Plume 1-2 are:
* Alternative GW1-A - No Further Action with Contingency (Continued Operation of the ECMWF
Air Stripper, Continued Operation of the On-Site Pump and Treat Systems, and Long-Term Ground-
Water Monitoring with Contingency)
Capital Cost: $0
Annual O&M Cost: $59,000
Present Worth (30 Year) Cost: $730,000
Estimated Construction Time Frame: None
For Plume 1-2, this alternative is called "No Further Action with Contingency" because several
remedial actions have already been implemented and a contingency is included in case future actions
are necessary. Remedial actions to date include: (1) an air stripper at the ECMWF which currently
treats 6 to 7 million gallons of water daily; (2) an on-site interim action pump and treat system
initiated in March 1994 which currently prevents the off-site migration of contaminants in Plume
1-2; and (3) the on-going cleanup work at Lagoon No. 1 as provided for in the October 1993
Administrative Order by Consent between U.S. EPA and NPI.
A ground-water study estimated that the existing ECMWF and on-site interim pump and treat system
would restore the off-site portion of the contaminated aquifer to meet PALs in about 160 years.
23
-------
This study utilized a retardation factor of five, thereby assuming that the aquifer would require five
complete flushes to achieve PALs.
U.S. EPA will evaluate the effectiveness of the selected remedy as part of the 5-year review process
for sites where wastes are left on site. If the data available at the first such review is insufficient for
a reliable trend analysis, evaluation of remedy performance will be completed in the subsequent
review or at some earlier time to be established during the initial 5-year review. An evaluation of
ground-water information gathered for each 5-year review will be used to determine whether or not
there is a need for additional actions to reduce cleanup times. The 5-year reviews would also
evaluate the technical impracticability of attaining PALs in the ground water. If U.S. EPA
determines that it is technically impracticable to achieve PALs, a Technical Impracticability ARAR
waiver under CERCLA may be granted for the Site. To the extent U.S. EPA's 5-year reviews
indicate that it is not technically or economically feasible to achieve PALs, NR 140.28 provides
substantive standards for granting exemptions from the requirement to achieve PALs. Such
exemption levels may not be higher than the Wisconsin ESs.
The ground-water cleanup goals (which must also be achieved within a reasonable period of time)
for the contaminants of concern are the PALs. However, the determination of whether additional
measures will be required for Plume 1-2 will be based on compliance/projected compliance with the
ESs within a reasonable period of time. For this type of situation, a reasonable period of time for
meeting the ESs (MCLs) can be defined as less than 30 years.
At each 5-year review or earlier, as necessary, U.S. EPA, in consultation with WDNR, will evaluate
the following criteria in order to determine the need for additional remedial measures:
•
1. Comparison of existing contaminant levels throughout the plume to ESs (MCLs);
2. Trends in contaminant concentrations, if any;
3. Effectiveness of the interim pump and treat system/location, in conjunction with
other source control measures, at cutting off the source of contamination at the NPI
Site from the downgradient off-site Plume 1-2;
4. Ability to improve the current interim pump and treat system to provide greater
effectiveness in cleaning up the downgradient plume;
5. Potential reduction in restoration timeframes to less than 30 years for ESs;
6. Potential for the contaminants in the ground water to reach asymptotic levels
throughout the plume;
24
-------
7. Negative impacts on the municipal water supply; and
8. Alternative remedial measures available to meet ground-water standards and the cost
thereof.
Additional measures will be necessary if an evaluation of the above criteria indicates: (1)
concentrations within Plume 1-2 have not decreased; (2) concentrations within Plume 1-2 do not
show the potential to decrease below ESs in less than 30 years; or (3) interim pump and treat
systems, in conjunction with other source control measures, do not meet their remedial objectives
of preventing off-site contaminant migration.
Long term ground-water monitoring would be conducted to monitor and insure the effectiveness of
this alternative. Ground-water monitoring results will be evaluated annually to aid in predicting
contaminant trends. A ground-water monitoring program to be developed during the design phase
shall include but not be limited to: development of a continuous monitoring record; identification
of select wells throughout the plume to monitor changes in both the horizontal and vertical extent
of the plume; sampling frequency; and identification and monitoring of areas containing higher
contaminant concentrations, if any.
If additional measures are determined to be necessary, they are likely to involve revised pump and
treat design or other remedial measures, including any applicable new technology. The applicability
of new technologies will be evaluated in terms of technical and economic feasibility. The design
of additional measures (should they be necessary) will include: locating extraction wells (or other
remedies) to maximize hydraulic capture of the plume; minimizing the impact on the municipal well
field in terms of both quantity and quality; and^ considering areas of greater contaminant
concentrations, if any.
This alternative includes any measures required to ensure the continued effectiveness of the ECMWF
air stripper and the long-term operation and maintenance thereof.
Alternative GW1-B - Pump and Treat by Cascade Aeration
Capital Cost: $550,000 to $1,270,000
Annual O&M Cost: $129,000 to $499,000
Present Worth (30 Year) Cost: $2,300,000 to $4,300,000
Estimated Construction Time Frame: one to two years
Under this alternative, the off-site ground water in Plume 1-2 would be pumped to reduce the time
required to capture the plume and clean up the aquifer. The ground-water study estimated that one
to two additional pump and treat systems would restore the off-site portion of the aquifer to meet
PALs in about 60 to 80 years. Water pumped from the new extraction wells would be treated by
cascade aeration and discharged to the Chippewa River through the City of Eau Claire storm sewer
system or discharged dkectly to the Chippewa River. Cascade aeration systems are currently being
25
-------
used at the NPI Site as part of the on-site interim action required in the 1991 ROD. Long-term,
ground-water monitoring would be conducted to insure the effectiveness of this alternative. The
effect of this alternative on the City of Eau Claire's water supply was not evaluated.
Alternative GW1-C - Pump and Treat by Air Stripping
Capital Cost: $737,000 to $ 1,800,000
Annual O&M Cost: $173,000 to $585,000
Present Worth (30 Year) Cost: $2,900,000 to $5,900,000
Estimated Construction Time Frame: one to two years
This alternative is similar to Alternative GWI-B except that the ground water would be treated by
air stripping (instead of cascade aeration) and discharged to the Chippewa River through the City
of Eau Claire storm sewer system, directly to the Chippewa River, or to recharge basins (areas where
treated ground water would trickle through the soils to ground water). Long-term, ground-water
monitoring and discharge water sampling would be conducted to insure the effectiveness of this
alternative.
PLUMES 3 AND 4
The alternatives evaluated for addressing Plumes 3 and 4 are:
•k
Alternative GW3-A - No Further Action (Continued Operation of the On-Site Pump and Treat
Systems, and Long-Term Ground-Water and Surface-Water Monitoring)
Capital Cost: $0
Annual O&M Cost: $62,000
Present Worth (30 Year) Cost: $764,000
Estimated Construction Time Frame: None
For Plumes 3 and 4, this alternative can be called "No Further Action" because significant cleanup
work has already been done at Plumes 3 and 4. This work includes the construction of a permanent
alternative drinking water supply for the area affected by Plumes 3 and 4, in accordance with the
August 1990 ROD. Additionally, under the 1990 ROD, 42 private wells in the affected area were
abandoned after residences and businesses were connected to the City of Eau Claire water supply.
Institutional controls are in effect to prevent area residences and businesses from using wells in the
area for drinking water: Residences in the area supplied with municipal water are allowed to use
private wells for other purposes, such as irrigation and car washing, as long as there is no connection
to indoor plumbing. To use these wells, property owners must submit applications for annual
permits to the Hallie Sanitary District.
26
-------
In addition, U.S. EPA issued a ROD in September 1991 which selected an interim action pump and
treat system to prevent the off-site movement of contaminants in Plume 3. This pump and treat
system began operating in March 1994. The interim action pump and treat system does not include
Plume 4 because this plume is entirely off site. Ground water in Plumes 3 and 4 downgradient of
the interim pump and treat system continues to discharge to Lake Hallie where the levels of VOCs
detected in water samples collected during the RI were below Wisconsin surface water quality
standards.
The ground-water study conducted as part of the RI estimated that the no-further-action alternative
would restore the off-site portion of the aquifer to meet PALs in about 120 years. As previously
indicated, this study assumed that five complete flushes of the aquifer would achieve PALs. Long-
term, ground-water and surface-water monitoring would be conducted to monitor and insure the
effectiveness of the no-further-action alternative. A final ground-water monitoring program would
be developed during the design phase. Surface-water monitoring would also be performed to track
contaminant levels in Lake Hallie to confirm that the lake is not affected by ground-water discharge
from Plumes 3 and 4.
Alternative GW3-B - Pump and Treat by Cascade Aeration
Capital Cost: $760,000 to $1,220,000
Annual O&M Cost: $188,000 to $653,000
Present Worth (30 Year) Cost: $3,200,000 to $5,000,000
Estimated Construction Time Frame: one to two years
Under this alternative, ground water would be pumped for the off-site portion of Plumes 3 and 4 to
reduce the time required to capture the plume and clean up the aquifer. The ground-water study
estimated that one to two additional pump and treat systems would restore the off-site portion of the
aquifer to meet PALs in about 35 to 40 years. Water pumped from the new extraction wells would
be treated by cascade aeration and discharged to the Chippewa River through the City of Eau Claire
storm sewer system or discharged directly to the Chippewa River. Long-term, ground-water
monitoring and discharge water sampling would be conducted to insure the effectiveness of this
alternative. Surface-water monitoring would also be performed to track contaminant levels in Lake
Hallie to confirm that the lake is not affected by ground-water discharge from Plumes 3 and 4.
Alternative GW3-C - Pump and Treat by Air Stripping
Capital Cost: $999,000 to $ 1,680,000
Annual O&M Cost: ' $216,000 to $732,000
Present Worth (30 Year) Cost: $3,900,000 to $6,400,000
Estimated Construction Time Frame: one to two years
This alternative is similar to Alternative GW3-B except that the water pumped from new extraction
wells would be treated by air stripping (instead of cascade aeration) and discharged to the Chippewa
27
-------
River through the City of Eau Claire storm sewer system, directly to the Chippewa River, or to
recharge basins. Long-term, ground-water monitoring and discharge water sampling would be
conducted to insure the effectiveness of this alternative. Surface-water monitoring would also be
performed to track contaminant levels in Lake Hallie to confirm that the lake is not affected by
ground-water discharge from Plumes 3 and 4.
PLUMES
The alternatives evaluated for addressing Plume 5 are:
JU
Alternative GW5-A - No Further Action (Continued Operation of the On-Site Pump and Treat
Systems, and Long-Term Ground-Water and Surface-Water Monitoring)
Capital Cost: $123,000
Annual O&M Cost: $62,000
Present Worth (30 Year) Cost: $887,000
Estimated Construction Time Frame: None
This alternative can be called "No Further Action" because significant work has already been done
at Plume 5 to eliminate the ground water exposure pathway. Similar to the work performed for
Plumes 3 and 4, a permanent alternative drinking water supply was constructed for the area affected
by Plume 5 in accordance with the August 1990 ROD. Although PALs were exceeded in Plume 5,
an interim pump and treat system using cascade aeration was not installed for this plume because
Wisconsin ESs and federal MCLs were not exceeded here. The VOC concentrations in Plume 5 and
in Lake Hallie water samples collected during the itl are below Wisconsin surface water quality
standards. The ground-water study estimated that the no-further-action alternative would restore the
aquifer to meet PALs in about 110 years.
The no-further-action alternative for Plume 5 would include long-term ground-water and surface-
water monitoring to insure the effectiveness of this alternative. A final ground-water and surface-
water monitoring program would be developed during the design phase.
Alternative GW5-B -Pump and Treat by Cascade Aeration
Capital Cost: $819,000 to $848,000
Annual O&M Cost: $169,000 to $441,000
Present Worth (30 Year) Cost: $3,200,000
Estimated Construction Time Frame: one to two years
Under this alternative, ground water would be pumped for the off-site portion of Plume 5 to reduce
the time required to capture the plume and clean up the aquifer. The ground-water study estimated
that one additional pump and treat system would restore the aquifer to meet PALs in about 60 years.
28
-------
Water pumped from the new extraction wells would be treated by cascade aeration and discharged
to the Chippewa River through the City of Eau Claire storm sewer system or discharged directly to
the Chippewa River. Long-term ground-water and surface-water monitoring as well as discharge
water sampling would be conducted to insure the effectiveness of this alternative.
Alternative GW5-C - Pump and Treat by Air Stripping
Capital Cost: $958,000
Annual O&M Cost: $ 193,000 to $470,000
Present Worth (30 Year) Cost: $3,600,000 to $3,800,000
Estimated Construction Time Frame: one to two years
This alternative is similar to Alternative GW5-B except that the water pumped from new extraction
wells would be treated by air stripping (instead of cascade aeration) and discharged to the Chippewa
River through the City of Eau Claire storm sewer system, directly to the Chippewa River, or to
recharge basins. Long-term, ground-water and surface-water monitoring as well as discharge water
sampling would be conducted to insure the effectiveness of this alternative.
VIII. SUMMARY OF COMPARATIVE ANALYSIS OF ALTERNATIVES
The following nine criteria, outlined in the NCP at 40 CFR 300.430(e)(9)(iii), were used to compare
the alternatives and to determine the alternative for remediation of the soils and ground-water
contamination that: (1) is protective of human health and the environment; (2) attains ARARs; (3)
is cost effective; and (4) represents the best balance among the evaluating criteria. The alternative
that meets the two '^threshold" requirements of protectiveness and ARAR-compliance, and provides
the "best balance" of trade-offs, with respect to the remaining criteria, is determined from this
evaluation.
A. THRESHOLD CRITERIA
OVERALL PROTECTION OF PUBLIC HEALTH AND THE ENVIRONMENT addresses
whether a remedy provides adequate protection of human health and the environment and describes
how risks posed by each exposure pathway are eliminated, reduced, or controlled through treatment,
engineering controls, or institutional controls.
Source Control Alternatives
Mel by Road and East Disposal Site
All Melby Road and East Disposal Site alternatives, with the exception of the No-Action Alternative,
would provide adequate protection to human health and the environment by eliminating exposure
to contaminated soil at the Site and preventing the migration of contaminants into the ground water.
On-site ground-water treatment systems currently prevent the off-site migration of contaminated
29
-------
ground water. Alternatives M-Bl, M-B2, M-CI, M-C2, and M-D1 would all cap and/or landfill the
wastes on site. Capping and/or landfilling would eliminate human health risks posed by direct
contact with contaminated soils by preventing exposure. For alternative M-B1, waste materials from
the East Disposal Site would be excavated and consolidated at the Melby Road Site for capping.
This option would create a single area for management of waste materials at the NPI Site. Capping
and/or landfilling also reduces the potential for further contamination of on-site ground water by
minimizing the infiltration of rainwater through contaminants and into ground water. In conjunction
with the multi-layer cap, alternatives M-Bl, M-B2, M-CI, and M-C2 include the installation of an
SVE system which would be designed to prevent future releases of VOCs into the ground water.
The SVE system would remove VOCs from the vadose zone and create a vapor barrier. The current
interim action pump and treat cascade aerator provides additional protection by preventing the off-
site migration of contaminated ground water.
Alternatives M-CI, M-C2, and M-D1 also provide for excavation, consolidation and disposal of
waste materials into a single landfill constructed at the NPI Site. In addition to eliminating human
health risks posed by direct contact, the landfill double liner and leachate collection system would
minimize vertical migration of contaminants from the landfilled wastes to on-site ground water.
Similarly, alternative M-D2, which disposes of all waste materials at an off-site landfill, would
eliminate human health risks posed by direct contact. The excavation and off-site land disposal of
these wastes would also eliminate contaminant migration from these wastes to the ground water.
Alternatives M-E and M-F would treat the contaminated soils by removing and/or destroying
organics. However, some organics and inorganics would remain in the treated materials and/or
residual ash which would require disposal at an on-site or off-site landfill.
Ditch 3
All Ditch 3 alternatives, with the exception of the No-Action Alternative, achieve protection of
human health and the environment by eliminating exposure to contaminated soil at the Site and
preventing migration of contaminants into the ground water. Alternatives D-B and D-C1 provide
for the excavation of waste materials in conjunction with capping or landfilling of wastes. Capping
and landfilling would eliminate human health risks posed by direct contact with contaminated soils
by eliminating the exposure pathway. Alternative D-B consolidates Ditch 3 wastes with those at
Melby Road, thereby creating a single area at the NPI Site for management of waste materials
remaining on site. Alternative D-B would only be implemented in conjunction with the multi-layer
cap and SVE system described in alternative M-Bl. As discussed previously, the objective of the
multi-layer cap and SVE would be to eliminate exposure to contaminated soil at the Site and prevent
migration of contaminants into the ground water.
Alternative D-C1 provides for excavation, consolidation and disposal of waste materials into a single
landfill constructed at the NPI Site. In addition to eliminating human health risks posed by direct
contact, the landfill double liner and leachate collection system would minimize vertical migration
of contaminants from the landfilled wastes to on-site ground water. Similarly, alternative D-C2,
which disposes of all waste materials at an off-site landfill, would eliminate human health risks
30
-------
posed by direct contact. The excavation and off-site land disposal of these wastes would also
eliminate contaminant migration from these wastes to the ground water.
Alternatives D-D and D-E would treat the contaminated soils by removing and/or destroying
organics. However, some organics and inorganics would remain in the treated materials and/or
residual ash which would require disposal at an on-site or off-site landfill.
Drv Wells 2 and 5
The No-Action Alternative, Alternative W-A, does not provide adequate protection of public health
and the environment because exposure to contaminated soils would continue. Alternative W-B
would achieve protection of human health and the environment by eliminating exposure to
contaminated soil at the Site and preventing migration of contaminants into the ground water. The
excavation and disposal of contaminated soils at an off-site landfill would eliminate the risk of
exposure to contaminated soil and leaching of contaminants into the ground water. The dry well area
soils will be disposed of at an off-site landfill due to the presence of PCBs.
Ground-Water Remedial Alternatives
Plume 1-2
As the result of the significant remedial work already performed at the Site and at the ECMWF, the
risk to human health posed by the presence of VOCs in the ground water has already been
significantly mitigated or eliminated. The ground water affected by Plume 1-2 is currently being
treated by a two column air stripper at the ECMWF prior to its distribution to the City's residents.
Water treated by the air stripper meets all federal regulatory requirements and Wisconsin ESs.
Furthermore, an on-site ground-water treatment system installed in 1994 currently prevents the off-
site migration of contaminants in Plume 1-2. U.S. EPA is unaware of any ecological harm created
by the VOCs present in Plume 1-2. Therefore, all Plume 1-2 alternatives achieve protection of
human health and the environment since exposure to contaminated ground water has already been
eliminated. Institutional controls are in effect to prevent area residences and businesses from using
wells in the area for drinking water. All of the alternatives provide for long-term ground-water
monitoring to track the effectiveness of this remedy.
The difference between the alternatives is the estimated time required to reach cleanup goals. It has
been estimated that it will take approximately 160 years for the existing ECMWF air stripper and
the on-site interim pump and treat system to restore the off-site portion of the aquifer to meet PALs.
Alternatives GW1-B and GW1-C which involve the installation of one to two additional ground-
water treatment systems (either cascade aerators or air strippers) within the plume would restore the
off-site portion of the aquifer to meet PALs in approximately 60 to 80 years.
31
-------
Plumes 3 and 4
Since a significant amount of remedial work has been performed at the Site, risk to human health
has already been significantly mitigated or eliminated The Hallie Sanitary District currently
provides a permanent alternate drinking water supply to the areas affected by Plumes 3 and 4. In
addition, 42 private wells in the affected areas were abandoned after residences and businesses were
connected to the City of Eau Claire water supply. Institutional controls are in effect to prevent area
residences and businesses from using wells in the area for drinking water. In addition, there is
currently an on-site ground water treatment system designed to prevent the off-site movement of
contaminants in Plume 3. Therefore, all alternatives for Plumes 3 and 4 achieve protection of human
health and the environment since exposure to contaminated ground water has been eliminated. All
of the alternatives provide for long-term ground-water monitoring to track the effectiveness of this
remedy.
The difference between the alternatives is the estimated time required to reach cleanup goals. It has
been estimated that it will take approximately 120 years for the existing on-site interim pump and
treat system to restore the off-site portion of the aquifer to meet PALs. Alternatives GW3-B and
GW3-C, which involve the installation of one to two additional ground-water treatment systems
(either cascade aerators or air strippers) within the plume, would restore the off-site portion of the
aquifer to meet PALs in approximately 35 to 40 years.
Plume 5
Since a significant amount of remedial work has been performed at the Site, risk to human health
has already been significantly mitigated or eliminated. The Hallie Sanitary District currently
provides a permanent alternate drinking water supply to the areas affected by Plume 5. Institutional
controls are in effect to prevent area residences and businesses from using wells in the area for
drinking water. Therefore, all alternatives for Plume 5 achieve protection of human health and the
environment by eliminating exposure to contaminated ground water. All of the alternatives provide
for long-term ground-water monitoring to track the effectiveness of this remedy.
The difference between the alternatives is the estimated time required to reach cleanup goals. It has
been estimated that the no-further-action alternative would restore the off-site portion of the aquifer
to meet PALs in approximately 110 years. Alternatives GW5-B and GW5-C, which involve the
installation of a ground-water treatment system (either a cascade aerator or an air stripper) within
the plume, would restore the off-site portion of the aquifer to meet PALs in approximately 60 years.
COMPLIANCE WITH APPLICABLE OR RELEVANT AND APPROPRIATE
REQUIREMENTS addresses whether a remedy will meet federal and state environmental statutes
and regulations and/or provides grounds for invoking a waiver.
Federal and state ARARs are summarized in Tables 2 and 3. U.S. EPA has determined that the
selected remedy will meet all ARARs.
32
-------
B. PRIMARY BALANCING CRITERIA
LONG-TERM EFFECTIVENESS AND PERMANENCE refers to the ability of a remedy to
maintain reliable protection of human health and the environment over time, once cleanup standards
have been met.
Source Control Alternatives
Melby Road and East Disposal Site
The no-further-action alternative, M-A, does not provide long-term effectiveness. All of the
remaining alternatives would provide good long-term effectiveness against direct contact with and
inhalation of soils and waste materials. Alternatives M-B1, M-B2, M-C1, M-C2, M-Dl and M-D2
include either capping or an on-site or off-site landfilling component for the contaminated soils. In
addition to a multi-layer cap, alternatives M-B1, M-B2, M-C1 and M-C2 include an SVE system
which would be designed to prevent the leaching of VOCs into the ground water, thereby enhancing
long-term effectiveness of the ground-water component of the remedy. Alternatives M-C1 and M-
C2 include the partial removal of source materials from Melby Road. Although some of the source
materials would be removed under these alternatives, a cap and SVE system are still included
because the remaining wastes could still pose potential ground-water contamination.
Alternatives M-Dl and M-D2 include the excavation of all contaminated soils from Melby Road and
East Disposal Sites and disposal of these wastes in either an on-site or off-site landfill. In addition
to eliminating human health risks posed by direct contact, the landfill double liner and leachate
collection system would minimize vertical migration ef contaminants from the landfilled wastes to
on-site ground water.
Alternatives M-E and M-F would treat the contaminated soils by removing and/or destroying
organics. However, some organics and inorganics would remain in the treated materials and/or
residual ash which would require disposal at an on-site or off-site landfill.
All of these alternatives would provide long term effectiveness as long as the integrity of the cap,
the landfill liner, leachate collection system and/or SVE system are maintained. Assuming good
construction quality of the containment components, the likelihood of remedy failure over time is
remote.
Ditch 3
The no-further-action alternative, D-A, would not provide long-term protection. All of the
remaining alternatives would provide good long-term protection against direct contact with and
inhalation of soils and waste materials. These remaining alternatives all provide for the excavation
of the contaminated soils from Ditch 3. Alternative D-B provides for consolidation and capping with
SVE at Melby Road while alternatives D-C1 and D-C2 provide for either on-site or off-site landfill
33
-------
of the contaminated soils. Alternatives D-D and D-E provide good long-term protection by treating
the contaminated soils and landfilling the remaining wastes at an on-site or off-site landfill.
Drv Wells 2 and 5
The no-further-action alternative, W-A, would not provide long-term effectiveness. Only alternative
W-B would provide good long-term protection against direct contact with and inhalation of soils and
waste materials because the contaminated soils are excavated and taken to an off-site landfill.
Ground-Water Remedial Alternatives
Plume 1-2
All of the alternatives would provide for long-term effectiveness and permanence. The drinking
water supply at the ECMWF is currently treated by a two-column air stripper before distribution.
Air strippers are a reliable and proven method of treating ground water contaminated with VOCs.
Monitoring safeguards ensure that the drinking-water quality continues to meet federal regulations,
Wisconsin ESs and, to a great extent, Wisconsin PALs. Enforcement activities associated with the
ECMWF have ensured continued effectiveness of the air strippers until U.S. EPA believes they are
no longer necessary for the protection of human health and the environment.
All of the alternatives would be effective in the long term because pumping at the ECMWF controls
further downgradient plume migration, while the interim pump and treat system at the southwestern
portion of the NPI Site was designed to prevent the off-site VOC migration in ground water. The
effectiveness of the remedy would be tracked by long-term ground-water monitoring. Pursuant to
the NCP, 5-year reviews will be conducted to determine if: 1) the pump and treat systems are
effectively reducing contaminant concentrations in the plume; 2) the effective limit of the remedy
has been reached; and 3) further remedial actions are needed. The estimated operating life of the
ECMWF air stripper, which went into service in 1987, is approximately 20-25 years. The expected
remaining life of the ECMWF air stripper is less than the restoration time (60 to 160 years) estimated
by the model used during the FS. The ECMWF air stripper would be upgraded or replaced, if
necessary.
Plumes 3 and 4
All of the alternatives would provide for long-term effectiveness and permanence. The Hallie
Sanitary District currently provides drinking water to the areas affected by Plumes 3 and 4. This
central distribution system is a reliable and proven method of providing a permanent drinking water
supply. Monitoring safeguards ensure that the drinking-water quality continues to meet federal and
state standards.
The effectiveness of the remedy would be tracked by long-term ground-water and surface-water
monitoring. Pursuant to the NCP, 5-year reviews would be conducted to determine if the pump and
34
-------
treat systems are effectively reducing contaminant concentrations in Plumes 3 and 4, if the effective
limit of the remedy has been reached or if additional actions are needed.
Plume 5
All of the alternatives would provide for long-term effectiveness and permanence. The Hallie
Sanitary District currently provides drinking water to the areas affected by Plume 5. This central
distribution system is a reliable and proven method of providing a permanent drinking water supply.
Monitoring safeguards ensure that the drinking-water quality continues to meet federal and state
standards.
The effectiveness of the remedy would also be tracked by long-term ground-water and surface-water
monitoring. Pursuant to the NCP, 5-year reviews would be conducted to determine if the remedy
is effectively reducing contaminant concentrations in Plume 5, if the effective limit of the remedy
has been reached, or if additional actions are needed.
REDUCTION OF CONTAMINANT TOXICITY, MOBILITY, OR VOLUME through
treatment addresses the anticipated performance of the treatment technologies a remedy may employ.
Source Control Alternatives
Melby Road and East Disposal Site
The no-further-action alternative, M-A, would not reduce contaminant toxicity, mobility, or volume.
Alternatives M-B1, M-B2, M-C1, M-C2, M-D1 and M-D2 are principally containment alternatives,
and would reduce contaminant mobility by capping the materials and/or landfilling them either on
site or off site. Alternatives M-B1, M-B2, M-C1 and M-C2 also include an SVE component in
conjunction with the cap, which would contain and remove VOCs from capped soils to reduce
contaminant volume. Alternative M-E uses the Ll ID treatment process to volatilize VOCs from
the contaminated soils. Alternative M-F uses incineration to destroy organics in the contaminated
soils, thereby reducing the toxicity, mobility and volume of the wastes.
Ditch 3
The no-further-action alternative, D-A, would not reduce contaminant toxicity, mobility, or volume.
Alternatives D-B, D-C1 and D-C2 reduce contaminant mobility by capping and/or landfilling the
contaminated soils. Both Alternatives D-D and D-E reduce the toxicity, mobility and volume
through treatment. Alternative D-D uses LTTD to volatilize VOCs from the soils while alternative
D-E uses incineration to destroy organics, thereby reducing the toxicity, mobility and volume
through treatment.

Drv Wells 2 and 5
The no-further-action alternative, W-A, would not reduce contaminant toxicity, mobility, or volume.
Alternative W-B reduces contaminant mobility by excavating and landfilling the contaminated soils
off site.
Ground-Water Remedial Alternatives
Plume 1-2
All alternatives, including no further action, provide treatment (cascade aeration or air stripping) to
reduce VOC concentrations in extracted ground water. Cascade aeration would be expected to
remove approximately 30-40% of VOCs (based on the performance of the interim action cascade
system), and air stripping would be expected to remove 99% of VOCs. The cascade aeration and
air stripping processes would transfer VOCs from ground water to the ambient air. The VOCs
removed from the water would not be destroyed, but would pose a much lower risk in the ambient
air where it is quickly dispersed and diluted.
Plumes 3 and 4
All alternatives, including no further action, include treatment (cascade aeration or air stripping) to
reduce VOC concentrations in extracted ground water. Cascade aeration would be expected to
remove approximately 30-40% of VOCs (based on the performance of the interim action cascade
systems), and air stripping would be expected to remove 99% of VOCs.
*
Plume 5
Alternatives GW5-B and GW5-C include either cascade aeration or air stripping to reduce VOC
concentrations in extracted ground water. Cascade aeration would be expected to remove
approximately 30-40% of the VOCs (based on the performance of the interim action cascade
systems), and air stripping would be expected to remove 99% of the VOCs.
SHORT-TERM EFFECTIVENESS considers the length of time needed to implement an
alternative and the risks the alternative poses to workers, residents and the environment during
implementation.
Source Control Alternatives
Melby Road and East Disposal Site
Implementation of alternatives M-A and M-B2 would produce minimal short-term impacts to the
community, workers or the environment since the contaminated soils would be left in place and
capped. Similarly, alternative M-B1, which involves the consolidation of minimal amounts of
36
-------
contaminated soil at Melby Road, would also produce minimal short-term impacts. However,
alternatives M-C1, M-C2, M-D1, M-D2, M-E and M-F involve significant excavation of waste
materials. This excavation and handling could generate dust in residential and commercial areas
which would require monitoring and control. Exposure risks to on-site workers during waste
excavation, hauling, and construction would be controlled by a site-specific Health and Safety Plan
("HASP"). Alternatives M-C1 and M-C2, which involve the movement of less material than M-D1,
M-D2, M-E and M-F, would also generate less dust.
Ditch 3
Alternative D-A would produce minimal short-term impacts to the community, workers or the
environment because the contaminated soils would be left in place. Alternatives D-B, D-C1, D-C2,
D-D, and D-E involve excavation of waste materials. This excavation and subsequent handling
could generate dust in residential and commercial areas which would require monitoring and control.
Exposure risks to on-site workers during waste excavation, hauling, and landfill construction would
be controlled by a site-specific HASP. Alternatives D-B and D-C2 would be of shorter duration
because the materials would either be consolidated with wastes at Melby Road or disposed of at an
off-site landfill.
Drv Wells 2 and 5
Alternative W-A would produce minimal short-term impacts to the community, workers or the
environment because the contaminated soils would be left in place. Alternative W-B would involve
the excavation and off-site landfill of the contaminated soils and sediments. This excavation and
subsequent handling could generate dust in residential and commercial areas which would require
monitoring and control. Exposure risks to on-site workers during waste excavation and hauling
would be controlled by a site-specific HASP.
Ground-Water Remedial Alternatives
Plume 1-2
All ground-water alternatives, including no further action, would achieve short-term effectiveness.
A site specific HASP would be implemented to protect the public and on-site workers who would
construct the remedy and who could be exposed to VOC-contaminated ground water. There are no
significant public health or environmental impacts anticipated in constructing or implementing the
remedial alternatives.
Plumes 3 and 4
All ground-water alternatives, including no further action, would achieve short-term effectiveness.
A site specific HASP would be implemented to protect the public and on-site workers who would
construct the remedy and who could be exposed to VOC-contaminated ground water. There are no
37
-------
significant public health or environmental impacts anticipated in constructing or implementing the
remedial alternatives.
Plume 5
All ground-water alternatives, including no further action, would achieve short-term effectiveness.
A site specific HASP would be implemented to protect the public and on-site workers who would
construct the remedy and who could be exposed to VOC-contaminated ground water. There are no
significant public health or environmental impacts anticipated in constructing or implementing the
remedial alternatives.
IMPLEMENTABILITY addresses the technical and administrative feasibility of a remedy,
including the availability of materials and services needed to implement a particular option.
Source Control Alternatives
Melbv Road and East Disposal Site
The no-action alternative could be implemented immediately. The multi-layer cap(s) specified in
alternatives M-B1, M-B2, M-CI and M-C2 could be readily constructed by local contractors. Multi-
layer capping is widely used to prevent human contact with contaminants and to reduce leachate
generation. Materials, equipment and labor are available to implement this alternative. An SVE
system could also be designed and installed by local contractors.
Materials, equipment, labor and space are readily available to construct the on-site hazardous waste
landfill specified in alternatives M-CI and M-Dl. Alternative M-D2 could also be implemented
upon the selection of an appropriate off-site hazardous waste landfill. Since there are no operating
hazardous waste landfills in Wisconsin, the excavated wastes would have to be transported to an out-
of-state hazardous waste landfill. The selection of the landfill would be based on its environmental
compliance status and its willingness to accept the wastes.
Alternatives M-E and M-F are more difficult to implement than the other alternatives because they
require pilot scale studies, specialized equipment and contractors experienced in these processes.
Ditch 3
The no-action alternative, D-A, could be implemented immediately. Compared to the remaining
alternatives, alternative* D-B would be the easiest to implement because it only involves the
excavation and consolidation of waste materials at Melby Road where a multi-layer cap compliant
with NR 660 would be installed. Alternatives D-C1 and D-C2 would require the construction of
a new landfill or rely on off-site disposal. Alternatives D-D and D-F would be the most difficult to
implement, relatively, because they would require pilot-scale studies.
38
-------
Drv Wells 2 and 5
The no-action alternative, W-A, could be implemented immediately. Alternative W-B is
implementable because the contaminated soils could be disposed of at a facility licensed to accept
PCB-contaminated wastes, based on the concentrations of PCBs detected in these materials.
Ground-Water Remedial Alternatives
Plume 1-2
The no-further-action alternative can be implemented almost immediately. Existing monitoring
wells could be utilized in the long-term ground-water monitoring program. Implementability
concerns for alternatives GW1-B and GW1-C include obtaining property access and the design and
construction of pump and treat systems which will meet surface water quality based WPDES
requirements. It may be necessary to treat the metals in the extracted ground water, modify or
relocate the outfall or obtain a variance to comply with the WPDES requirements. The use of
municipal storm sewers and/or obtaining property rights and easements from local government and
private landowners to construct on-site recharge basins or discharge pipelines could also pose
implementation problems. Finally, although the impact of alternatives GW1-B and GW1-C on the
ECMWF has not been modeled, the City of Eau Claire has expressed concern, based on the
principles of hydraulics, that extraction wells located upgradient of the well field would reduce the
volume and possibly affect the direction of ground-water flow to the well field, thereby decreasing
the volume and/or quality of water currently available.
Plumes 3 and 4 *
The no-further-action alternative can be implemented almost immediately. Existing monitoring
wells could be utilized in the long-term ground-water monitoring program. Implementability
concerns for alternatives GW3-B and GW3-C include the design and construction of pump and treat
systems which will meet surface water quality based WPDES requirements. It may be necessary to
treat the metals in the extracted ground water, modify or relocate the outfall or obtain a variance to
comply with the WPDES requirements. Additional implementability concerns include the use of
Eau Claire storm sewers, construction on private and municipal property, and construction across
local roads.
Plume 5
The no-further-action alternative can be implemented almost immediately. In conjunction with
existing monitoring wells, additional ground-water monitoring wells may be installed for the long-
term ground-water monitoring program. Implementability concerns for alternatives GW5-B and
GW5-C include the design and construction of pump and treat systems which will meet surface
water quality based WPDES requirements. It may be necessary to treat the metals in the extracted
ground water, modify or relocate the outfall, or obtain a variance to comply with the WPDES
39
-------
requirements. Additional implementation concerns include the use of municipal storm sewers,
construction on private and municipal property, and construction across local roads.
COST includes estimated initial capital, operation and maintenance ("O&M") costs, and net present
worth costs.
The estimated costs for all of the FS alternatives are listed below. The first column lists the capital
or construction costs for the project The second column lists the costs to operate the remedial
system once it is constructed. The final column represents the sum of the first two columns.

C. MODIFYING CRITERIA
STATE ACCEPTANCE indicates whether, based on its review of the RI/FS and Proposed Plan,
the State concurs with, opposes, or has no comment on the preferred alternative at the present time.
The State of Wisconsin has assisted in the development and review of materials in the
Administrative Record. The State's position regarding the selected alternative is discussed in the
statement issued by WDNR at the meeting on the Proposed Plan, September 29,1995, and in a letter
dated December 27,1995. However, based on further discussions between the State and U.S. EPA,
the State is expected to concur on the remedy selected in this ROD.
COMMUNITY ACCEPTANCE is based on comments received from the public during the public
comment period. Comments have been submitted by the community and local government officials.
The specific comments received are summarized in the attached Responsiveness Summary, along
with U.S. EPA's responses to such comments.
IX. THE SELECTED REMEDY
Based on its complete evaluation of the alternatives, U.S. EPA believes that the selected remedy
(Alternatives M-B1, D-B, W-B, GW1-A, GW3-A and GW5-A) will be protective of human health
and the environment, comply with ARARs, be cost effective, and will utilize permanent solutions
to the maximum extent practicable. U.S. EPA believes that the selected remedy satisfies all of the
threshold criteria and represents the best balance of trade-offs among the remaining criteria of the
NCP.
*
The components of the selected remedy are as follows:
Soil Vapor Extraction System
An SVE system will be installed and monitored at the Melby Road Disposal Site prior to installation
of the multi-layer cap in order to identify the location of possible hotspots (areas of concentrated
waste materials). If hotspots are identified, they will be excavated and disposed of in an off-site
disposal facility. This hotspot removal approach will reduce the possibility that future waste
removal would be required after the cap is installed. There is, however, no certainty that "hotspots"
will be identified because either they do not exist or the SVE system will not detect their location.
The SVE system will be designed to prevent future releases of VOCs into the ground water. A soil
gas monitoring program will be implemented to monitor the effectiveness of the SVE system.
Consolidation of Wastes at Melbv Road Disposal Site
Approximately 1,300 and 3,000 cy of soil mixed with waste forge compound will be excavated from
the East Disposal Site and Drainage Ditch 3, respectively. These materials will be consolidated with
42
-------
waste at the Melby Road Disposal Site, thereby creating a single waste management unit at the NPI
Site.
Multi-Laver Cap
A multi-layer cap compliant with Wisconsin Chapter MR 660 will be installed to cover all of the
waste materials at the Melby Road Disposal Site. This cap will eliminate or significantly mitigate
the potential for direct human contact with wastes and would reduce leachate generation at the NPI
Site. The exact configuration of the Melby Road Disposal Site cap would be determined during
Remedial Design. A typical cap consists of a synthetic, plastic membrane over a 2-foot-thick soil
layer, a 1-foot-thick sand drainage layer, and an approximate 2-foot-thick topsoil layer. The topsoil
layer will be seeded so that it would eventually be covered with grass. A ground-water monitoring
program will be implemented upgradient and downgradient of the capped areas to monitor the
effectiveness of the cap in reducing contaminant migration to ground water. The overall
effectiveness of the cap will be tracked via a long-term ground-water monitoring system. U.S. EPA
will seek deed restrictions limiting land use in the future development of the capped area.
Excavation and Off-Site Disposal
Approximately 50 cy of contaminated soils and sediments at Dry Wells 2 and 5 will be excavated,
treated (if necessary), and disposed of in an off-site landfill. Due to the presence of PCBs and metals
in these materials, they will be disposed of at a facility licensed to accept PCB-contaminated wastes.
Ground-Water Monitoring
*
Long term ground-water monitoring would be conducted to monitor and insure the effectiveness of
the no-further-action with contingency alternative for Plume 1-2 and the no-further-action
alternatives for Plumes 3,4 and 5. Ground-water monitoring results will be evaluated annually to
aid in predicting contaminant trends. A ground-water monitoring program to be developed during
the design phase shall include but not be limited to: development of a continuous monitoring record;
identification of select wells throughout the plume to monitor changes in both the horizontal and
vertical extent of the plume; sampling frequency; and identification and monitoring of areas
containing higher contaminant concentrations, if any.
U.S. EPA will evaluate the effectiveness of the selected remedy as part of the 5-year review process
for sites where wastes are left on site. If the data available at the first such review is insufficient for
a reliable trend analysis, evaluation of remedy performance will be completed in the subsequent
review or at some earlier time to be established during the initial 5-year review. An evaluation of
ground-water information gathered for each 5-year review will be used to determine whether or not
there is a need for additional actions to reduce cleanup times. The 5-year reviews would also
evaluate the technical impracticability of attaining PALs in the ground water. If U.S. EPA
determines that it is technically impracticable to achieve PALs, a Technical Impracticability ARAR
waiver under CERCLA may be granted for the Site. To the extent U.S. EPA's 5-year reviews
43
-------
indicate that it is not technically or economically feasible to achieve PALs, NR 140.28 provides
substantive standards for granting exemptions from the requirement to achieve PALs. Such
exemption levels may not be higher than the Wisconsin ESs.
The ground-water cleanup goals (which must also be achieved within a reasonable period of time)
for the contaminants of concern are the PALs. However, the determination of whether additional
measures will be required for Plume 1-2 will be based on compliance/projected compliance with the
ESs within a reasonable period of time. For this type of situation, a reasonable period of time for
meeting the ESs (MCLs) can be defined as less than 30 years.
At each 5-year review or earlier, as necessary, U.S. EPA, in consultation with WDNR, will evaluate
the following criteria in order to determine the need for additional remedial measures:
1. Comparison of existing contaminant levels throughout the plume to ESs (MCLs);
2. Trends in contaminant concentrations, if any;
3. Effectiveness of the interim pump and treat system/location, in conjunction with
other source control measures, at cutting off the source of contamination at the NPI
Site from the downgradient off-site Plume 1-2;
4. Ability to improve the current interim pump and treat system to provide greater
effectiveness in cleaning up the downgradient plume;
5. Potential reduction in restoration timeframes to less than 30 years for ESs;
6. Potential for the contaminants in the ground water to reach asymptotic levels
throughout the plume;
7. Negative impacts on the municipal water supply; and
8. Alternative remedial measures available to meet ground-water standards and the cost
thereof.
Additional measures will be necessary if an evaluation of the above criteria indicates: (1)
concentrations within Plume 1-2 have not decreased; (2) concentrations within Plume 1-2 do not
show the potential to decrease below ESs in less than 30 years; or (3) interim pump and treat
systems, in conjunction with other source control measures, do not meet their remedial objectives
of preventing off-site contaminant migration.
For Plumes 3,4 and 5, the 5-year review will utilize ground-water monitoring data to evaluate the
effectiveness of source cleanup actions and the need for additional actions.
44
-------
Surface Water Monitoring
Long-term surface-water monitoring will be performed for Plumes 3,4 and 5 to monitor and ensure
the effectiveness of the no-further-action alternative. Specifically, contaminant levels in Lake Hallie
will be tracked through surface water monitoring to confirm that the Lake is not affected by ground-
water discharge from Plumes 3,4 and 5.
X. STATUTORY DETERMINATIONS
U.S. EPA's primary responsibility at Superfund sites is to select and implement remedial actions that
achieve adequate protection of human health and the environment Section 121 of CERCLA
establishes several statutory requirements and preferences. When complete, a remedy selected by
U.S. EPA must comply with ARARs under federal and state environmental laws (unless a statutory
waiver is justified). The selected remedy must also be cost effective and utilize permanent solutions
and alternative treatment or resource recovery to the maximum extent practicable. Finally, the
statute includes a preference for remedies that employ treatment processes that permanently and
significantly reduce the toxicity, mobility or volume of hazardous substances, pollutants and
contaminants. The implementation of the selected remedy at the NPI Site satisfies these
requirements and preferences as follows:
A. Protection of Human Health and the Environment
The selected remedy will protect human health and the environment by eliminating exposure to
contaminated soil at the Site and preventing the migration of contaminants into the ground water.
On-site ground-water treatment systems currently psevent the off-site migration of contaminated
ground water and reduce the volume of VOCs in on-site ground water. The installation of an SVE
system at Melby Road will be designed to prevent future releases of VOCs into the ground water and
reduce the volume of VOCs in on-site soils. The SVE system will remove VOCs from the vadose
zone and create a vapor barrier. Capping the soils at Melby Road will eliminate human health risks
posed by direct contact with contaminated soils by eliminating the exposure pathway. Waste
materials from the East Disposal Site and Drainage Ditch 3 will be excavated and consolidated at
the Melby Road Site where a multi-layer cap compliant with NR 660 will be installed. The
consolidation of these waste materials will create a single area for management of waste materials
at the NPI Site.
Institutional controls are now in effect to prevent area residences and businesses from using wells
in the areas affected by Plumes 1-2,3,4 and 5 for drinking water. Residences in areas supplied with
municipal water are allowed to use private wells for other purposes, such as irrigation and car
washing, as long as there is no connection to indoor plumbing. To use these wells, property owners
must submit annual permit requests to either the City of Eau Claire's Health Department or the
Hallie Sanitary District.
45
-------
The long-term ground-water and surface-water monitoring will be conducted to ensure the
effectiveness of the no-further-action alternative for Plumes 1-2,3,4 and 5. A final ground-water
and surface-water monitoring program will be developed during the design phase. The ECMWF air
stripper will continue to operate until such treatment is no longer needed to achieve regulatory levels.
B. Attainment of ARARs
The selected remedy will meet all ARARs under federal, and more stringent state environmental
laws. A list of ARARs for the Site is contained in Tables 2 and 3. The primary ARARs that will
be achieved by the selected remedy are:
1. Chemical Specific
Chemical-specific ARARs include those laws and requirements that regulate the release of
contaminants to the environment. These include:
Clean Air Act [42 U.S.C § 7401 et seq.]; Wisconsin Environmental Protection Law,
Subchapter Hi-Air Pollution [Wis. Stat. 14430-144.426]
40 CFR 50; Wis. Admin. Code NR 404, 445 - Air Pollution Control Regulations. These regulations
establish standards for emission of pollutants into the ambient air. Since the selected remedy
involves excavation, construction and SVE activities which may release contaminants or particulates
into the air, emission requirements promulgated under this act are relevant and appropriate. The
need for treatment of air emissions produced by these processes would be determined based on
substantive requirements of Wis. Admin. Code NR 4^5. If emissions are expected to exceed those
standards, the remedy will be designed to reduce such emissions to acceptable levels or provide for
treatment to satisfy these Wisconsin standards.
Safe Drinking Water Act [40 U.S.C. § 300 et seq.]
40 CFR 141, Wis. Admin. Code NR 109 - MCLs. MCLs establish drinking-water standards for
potential and actual drinking water sources. MCLs have been exceeded at the Site in the aquifer
affected by Plume 1-2 which is presently being used as a drinking water source by the City of Eau
Claire. A two-column air-stripper currently treats the water in Plume 1-2 before its distribution to
the municipal water supply. Water treated by the air strippers meets all MCLs and non-zero
Maximum Contaminant Level Goals ("MCLGs"). MCLs have also been exceeded in Plumes 3 and
4, which no longer serve as a drinking water supply. MCLs have been attained, but not exceeded,
in Plume 5, which also no longer serves as a drinking water supply. The selected remedy achieves
compliance with MCLs and non-zero MCLGs.
Wis. Admin. Code NR 140 - Ground Water Quality Standards. These standards provide for ground-
water quality standards including PALs, Wisconsin ESs, and Wisconsin Alternative Concentration
Limits ("WACLs"). The selected remedy, building on the previous OUs, is intended to achieve
46
-------
compliance with PALs at all monitoring points. To the extent U.S. EPA's 5-year reviews indicate
that it is not technically or economically feasible to achieve PALs, NR 140.28 provides substantive
standards for granting exemptions from the requirement to achieve PALs. Such exemption levels
may not be higher than the Wisconsin ESs. U.S. EPA also has a procedure for granting a technical
impracticability waiver under CERCLA.
Wisconsin Environmental Protection Law, Subchapter II-Water and Sewage [Wis. Stat.
§ 144.02-27]
Wis. Admin. Code NR 102 and 105 - Surface water quality standards. NR 102 creates an
antidegradation policy for all waters of the state and prohibits toxic substances in surface waters at
concentrations which adversely affect public health or welfare, present or prospective water supply
uses, or protection of animal life. Surface water samples collected from Lake Hallie during the RI
showed that contaminant concentrations were well below Wisconsin surface water quality standards.
Toxic Substances Control Act [15 U.S.C. § 2601 et seq.]
40 CFR 761; Wis. Admin. Code NR 157 - Management ofPCBs and Products Containing PCBs.
These provisions are applicable to the storage, collection, transportation, processing and final
disposal of PCBs and products containing PCBs.
2. Action Specific
Wis. Admin. Code NR 141 - Ground-Water Monitoring Well Requirements. These requirements
establish minimum acceptable standards for the design, installation, construction, abandonment and
documentation of ground-water monitoring wells, and are applicable to the existing monitoring wells
and any to be installed as part of the long-term monitoring program.
Wis. Admin. Code NR 718 - Management of solid wastes excavated during response actions. These
requirements are applicable for the storage, transportation, treatment and disposal of contaminated
soil and certain other solid wastes excavated during response actions.
Wis. Admin. Code NR 720 - Soil Cleanup Standards. These soil standards were developed based on
the ground-water standards (PALs) of Chapter NR 140 for the ground-water exposure pathway.
These soil standards were designed to assure that ground-water standards will not be exceeded due
to leaching of residual contamination from the soil to the ground water. These requirements apply
to soils remaining at Ditch No. 3 and the East Disposal Site after excavation and consolidation at the
Melby Road Disposal Site.
47
-------
Resource Conservation and Recovery Act ("RCRA"), as amended [42 U.S.C. § 6901 ct seq.];
Wisconsin Environmental Protection Law, Hazardous Waste Management Act [Wis. Stat.
§ 144.60-74]
Most federal RCRA requirements are administered under the State of Wisconsin's equivalent
regulations. U.S. EPA has determined that the waste forge compound contains the spent solvent
TCA which is a listed hazardous waste pursuant to NR 605.09 of the Wisconsin Administrative Code
(Wisconsin's equivalent to the federal table of hazardous wastes from non-specific sources, 40
C.F.R. § 261.31). Excess forge compound generated during NPI's production processes was mixed
and co-disposed of with spent TCA, forming a combined waste stream which must be treated as a
listed hazardous waste. RCRA hazardous waste treatment and disposal regulations are therefore
applicable. The following requirements are also applicable or relevant and appropriate:
Wis. Admin. Code NR 605; 40 CFR 261 - Identification of Hazardous Wastes. Provides
requirements for determining when a waste is hazardous. The substantive requirements of these
regulations will apply to any on-site TCLP testing of treatment residuals and waste excavated at the
Site which may be disposed of off-site.
Wis. Admin. Code NR 615; 40 CFR 262 - Standards Applicable to Generators of Hazardous Waste.
These standards provide requirements for the shipment of wastes to treatment, storage or disposal
facilities. These requirements apply to on-site preparations for off-site shipment of dry well soils
and other wastes.
Wis. Admin. Code NR 620; Department of Transportation Hazardous Materials Transportation Act
[49 U.S. C. § 1801]; 40 CFR 263 - These standards are applicable to transporters of hazardous waste.
They require record keeping, reporting and manifesting of waste shipments. These requirements
are relevant and appropriate to on-site preparations for off-site shipment of dry well soils and other
wastes.
Wis. Admin. Code NR 630.10-17; 40 CFR 264f Subpart B - General Facility Requirements. These
requirements establish substantive requirements for security, inspection, personnel training, and
materials handling which are relevant and appropriate to on-site activities involving excavations and
handling of hazardous soils and materials.
Wis. Admin. Code NR 630.21-22; 40 CFR 264t Subpart D - Contingency Plan and Emergency
Procedures. These procedures establish substantive requirements for emergency planning which
are relevant and appropriate for on-site activities involving excavation and handling of hazardous
substances.
Wis. Admin. Code NR 675; 40 CFR 268 - Land Disposal Restrictions ("LDRs "). These regulations
govern the storage and land disposal of hazardous waste. Consolidation of waste materials will
occur within the area of contamination at the NPI Site. Therefore, the requirements of these
regulations will not be triggered for on-site soil consolidation. LDR requirements will be applicable,
48
-------
however, to any off-site treatment of the wastes excavated from Dry Wells 2 and 5 or hotspot wastes
excavated from Melby Road that are RCRA hazardous waste.
3. Location -Specific
Location-specific ARARs are those requirements that relate to the geographical location of a site.
No location-specific ARARs have been identified for this action.
4. To Be Considered
Federal and state policies and guidance to be considered are listed in Tables 4 and 5.
C. Cost Effectiveness
The selected remedy is the most cost-effective remedy that also achieves ARARs and satisfies the
other criteria of the NCP and Section 121 of CERCLA.
D. Utilization of Permanent Solutions and Alternative Treatment Technologies to the Maximum
Extent Practicable
U.S. EPA has determined that the selected remedy represents the maximum extent to which
permanent solutions can be utilized in the most cost-effective manner to eliminate exposure to
contaminated soil at the Site and prevent the continued migration of contaminants into the ground
water. Of the alternatives that are protective of human health and the environment and comply with
ARARs, U.S. EPA has determined that the selected alternative provides the best balance in terms
of long-term effectiveness and permanence, reduction in toxicity, mobility or volume through
treatment, short-term effectiveness, implementability, cost and consideration of state and community
acceptance.
E. Preference for Treatment As A Principal Element
The SVE will provide both treatment and containment of VOCs in the soils to be consolidated at the
Melby Road Disposal Site. An SVE system will be installed to remove VOCs from the soils and
to provide a vapor barrier to prevent the migration of VOCs into the ground water. Based on the
SVE pilot study, it is anticipated that a treatment system will not be required for SVE emissions.
However, the emissions from the full scale SVE system will be tested and a treatment system
installed if emission levels exceed state and federal standards. The contaminated soils from
Drainage Ditch No. 3 and the East Disposal Site will be consolidated at Melby Road where a multi-
layer cap compliant with NR 660 will provide long-term protection against direct contact and
inhalation of contaminated soils. The cap and SVE system at the Melby Road Site will significantly
reduce the mobility of hazardous substances.
49
-------
This final remedy at the NPI Site builds upon two previous OUs, the ECMWF remedy, and on-going
removal work. The combined cleanup work at the NPI Site satisfies the statutory preference for
treatment. A two-column air stripper was installed at the ECMWF to treat contaminated ground
water in Plume 1-2, and two cascade aeration systems were installed on the NPI Site to prevent the
off-site migration of contaminated ground water in Plumes 1-2 and 3. Removal work to date has
included the excavation of sludges and contaminated soils from Lagoon No. 1, which was then used
as supplemental fuel for cement kilns.
XI. RESPONSIVENESS SUMMARY
This Responsiveness Summary has been prepared to meet the requirements of Sections
113(k)(2)(B)(iv) and 117(b) of CERCLA, as amended by SARA, which requires U.S. EPA to
respond <4to each of the written or oral presentations" on a Proposed Plan for remedial action. On
September 20, 1995, U.S. EPA made available to the public for review and comment the FS and
Proposed Plan for the final remedy at the NPI Site. U.S. EPA received comments at the public
meeting on September 27,1995, at the Hallie Town Hall. Additional written comments were also
submitted to U.S. EPA during the comment period. This Responsiveness Summary summarizes
those comments and concerns expressed by the public and other interested parties in written and oral
form on the recommended remedy.
Summary of Comments Received During the Public Comment Period
Comments received during the public comment period are summarized in this section. Some of the
comments have been paraphrased in order to effectively summarize them in this document. For the
sake of consistency and privacy, U.S. EPA has referred to all individual commenters as "he." The
reader is referred to the public meeting transcript and copies of written comments submitted, all of
which are contained in the Administrative Record for the NPI Site. The Administrative Record is
available for review at the information repositories.
Comment: The City of Eau Claire expressed opposition to U.S. EPA's recommended cleanup
remedy for the NPI Site because it believed that the plan does not guarantee the protection of human
health. The City expressed concern that 44the proposed plan alters the previous assumption that
treatment of contaminated ground water at the Eau Claire municipal well field was short term. The
physical facilities and contractual guarantees do not exist to assure long-term treatment of the water
supply. We were unable to identify anything in the proposed plan that addressed this issue."
The commenter further stated, "The plan relies totally on long-term treatment of the leading edge
of Plumes 1-2 at the municipal well field to protect the health and environment. However, the plan
does not address long-term treatment. The plan indicates that this alternative has no additional
capital cost. In addition, the plan indicates that treatment will continue in accordance with a
previous record of decision. Previous actions provide only interim treatment guarantees."
50
-------
U.S. EPA Response: U.S. EPA believes that the selected remedy adequately assures the long-term
protection of human health by providing for the continued operation and maintenance of the air
stripper at the ECMWF. The proposed plan states that the recommended "alternative includes any
measures required to insure the continued effectiveness of the ECMWF air stripper and their long-
term operation and maintenance." Moreover, the 1993 ECMWF Cost Recovery Consent Decree
executed by U.S. EPA and NPI specifically states that NPI "shall be liable for all Operation and
Maintenance costs until such time that U.S. EPA determines, consistent with the final Record of
Decision for the National Presto Industries, Inc. Superfund site, that the obligation shall cease." The
final ROD for the NPI Site does provide for the long-term operation and maintenance of the
ECMWF air stripper as well as any future measures required to ensure its continued effectiveness.
U.S. EPA is aware that the anticipated remaining life of the ECMWF air stripper is less than the
estimated restoration time of the plume, but has provided in this ROD for the upgrade or replacement
of the ECMWF air stripper, if necessary.
U.S. EPA disagrees with the City's position that the selected remedy relies solely on treatment at
the municipal well field to protect human health and the environment In addition to the air stripper
at the municipal well field, two pump and treat systems currently operate at the NPI Site to prevent
the off-site migration of contaminated ground water in Plumes 1-2 and 3. In addition, the proposed
plan includes long term ground-water monitoring to insure the effectiveness of the alternative.
Although additional capital costs for the air stripper were not included in the proposed plan, the
ECMWF Consent Decree provides the mechanism by which such costs could be provided. With
respect to the ground-water treatment systems currently operating in accordance with previous
RODs, the final ROD provides for the long-term operation of these systems.
Comment: One commenter wanted to be assured th#t "there is no ground-water contamination in
an area outside the designated area." The commenter wanted further assurances that Lake Hallie is
cleaned up, no waste is being discharged in the Lake, and that "the ground water quality is good."
The commenter felt that it should be U.S. EPA's responsibility to extend water lines if the ground
water travels beyond the affected area.
U.S. EPA Response: The final boundaries of the affected area were determined based on the results
of extensive private and monitoring well sampling conducted from 1985 to 1989. The data
generated during the NPI RI was integrated with the historical database to ensure that the affected
area encompassed private wells contaminated or threatened by contamination from the NPI Site.
The Hallie Sanitary District currently serves the areas impacted or threatened by contamination from
Plumes 3,4 and 5. Based on further sampling of private wells after the creation of the District, it
is highly unlikely that the plumes will travel beyond the presently defined affected areas. Moreover,
the 1991 ROD provided for on-site pump and treat systems to prevent the off-site migration of
contaminated ground water from the NPI Site.
All of the surface-water samples collected during the RI show VOC levels in Lake Hallie remain
well below U.S. EPA's ambient water quality criteria and Wisconsin's surface water quality
51
-------
standards. Since the area is currently served by the Hallie Sanitary District, the ground water poses
no risk to human health.
Comment: One resident stated that he was happy to be receiving water from the Hallie Sanitary
District and that he would like to see the District expanded. Furthermore, he hoped that U.S. EPA's
selections will be the best and work will begin soon.
U.S. EPA Response: U.S. EPA is pleased to hear that residents are happy with the water from the
Hallie Sanitary District. The District was originally formed to provide drinking water to all areas
affected by Plumes 3, 4 and 5. Additional expansion of the District would be based on the local
residents' desire for expansion.
Comment: One commenter expressed concern about the contamination that still exists in the NPI
lagoons and that contaminants could continue leaching into the ground water. The commenter was
concerned that the rapid growth in the nearby communities would require additional clean water in
the near future.
U.S. EPA Response: NPI is currently in the process of cleaning up Lagoon No. Tin accordance with
the 1993 Administrative Order on Consent. Following the excavation of all liquids and solid wastes,
an investigation of the underlying soils will be performed to determine whether these soils contain
residual contamination. If U.S. EPA determines that contaminants in the remaining soils are still
migrating into the ground water at levels above Wisconsin PALs, WDNR has indicated that it
believes further remediation of these soils may be required. It is important to note that the pump and
treat cascade aeration system at the NPI Site currently prevents contaminated ground water from
migrating off-site. U.S. EPA fully expects that the Hallie Sanitary District will be able to supply
water for the expanding local communities.
Comment: Although one commenter was in favor of continued cleanup measures, he expressed
concern that the ground-water cleanup timeframes are too long.
U.S. EPA Response: It is important to understand the ground-water cleanup timeframes given in
the proposed plan are merely estimated timeframes based on ground-water models. In determining
the estimated time frames, conservative numbers were input into the models. Actual clean up times
may vary based on existing field conditions. All of the ground-water cleanup alternatives involve
lengthy cleanup timeframes. U.S. EPA regulations require that, in choosing among the alternatives,
it must balance a variety of factors which include, among others, implementability and cost
effectiveness. U.S. EPA determined that, despite the ground-water cleanup time frame, the selected
remedy represented the'best balance of the criteria that must be taken into account.
Comment: One commenter felt that if taxpayer money is used, all the costs and payments should
be fully open to the public.
52
-------
U.S. EPA Response: U.S. EPA periodically generates an itemized cost summary of its expenditures
at the NPI Site, which could be made available upon request.
Comment: One commenter felt that a leachate collection system should be installed to collect
contaminants that may leach from the waste mixture at the Melby Road Site. The commenter felt
that contaminants above existing standards will continue to migrate off site in violation of state law
without a leachate collection system. An alternative that does not eliminate or totally control the
contaminants is unacceptable.
U.S. EPA Response: U.S. EPA believes that a leachate collection system would be unnecessarily
duplicative of the on-site pump and treat systems. These systems were designed to prevent the off-
site migration of contaminated ground water above state and federal standards. Moreover, the Melby
Road cap will be constructed to minimize leachate generation, and the SVE system will be designed
to prevent the migration of VOCs into the ground water. U.S. EPA has concluded, therefore, that
the proposed remedy totally controls the off-site movement of the contaminants of concern at the
NPI Site.
Comment: One commenter recommended a newly developed technology for rapid remediation of
soils and ground water. This process is known as Geo-Cleanse and utilizes a method of injecting
hydrogen peroxide to oxidize contaminants.
U.S. EPA Response: U.S. EPA has reviewed literature provided by S & S Industrial Services, Inc.
on the Geo-Cleanse Process and evaluated its potential use in the remediation at the NPI Site. Based
on the review of the case studies included with the literature, the Geo-Cleanse process would not be
viable for the waste materials at the NPI Site because the chlorinated solvents are entrapped within
the highly impermeable waste forge compound and areas containing chlorinated solvents have not
been defined at the NPI Site. The literature states that hydraulic fracturing may be used to increase
the permeability of the material to be treated; however, a process like hydraulic fracturing would
not be a viable method of increasing the permeability of the waste forge compound.
Furthermore, the case studies presented with the study are for localized ground-water contamination
contained within a few hundred square feet. The major plumes originating from the NPI Site are
16,000 feet and 7,000 feet long, respectively. If these plumes were to be treated using the Geo-
Cleanse process, several hundred injector wells would be required within the plume area. In
addition, obtaining access for placement of injector wells may be difficult because the ground-water
plumes at NPI run under several heavily developed areas. In addition to the installation of injector
wells, several buildings may be required for chemical mixing, control panels and utilities. Finally,
the process may also require the addition of an iron catalyst to generate a hydroxyl radical. The iron
eventually precipitates out and the process may also precipitate other metal compounds, thereby
adversely affecting the porosity of the aquifer. Even if the Geo-Cleanse process were viable for
ground-water treatment at the NPI Site, it would be very difficult to implement and most likely cost
prohibitive due to the lengths of the plumes.
53
-------
U.S. EPA has additional concerns about the other ingredients (besides hydrogen peroxide and iron)
which may be added to the injection solution. Even though the literature claims that the additives
are environmentally safe, the type of additives was not disclosed in the literature and therefore, this
statement cannot be verified. The literature states that excess additives will be utilized by the soil
and ground-water micro-organisms as a nutrient source. The ground water at NPI does not require
a nutrient source. Although excess hydrogen peroxide would decompose into oxygen and water, any
other additive could result in ground-water contamination. Since the Geo-Cleanse process does not
address removal of excess additives, the additives would need to be carefully studied to determine
its effect on ground-water quality and the aquifer.
Comment: One commenter requested an evaluation of a filtration system on the SVE stack for
capturing VOC emissions or at least requiring testing of the stack gases to make sure that the
emissions do not exceed allowable levels under state and federal standards.
U.S. EPA Response: Based on the SVE pilot study performed at the Site, it is not anticipated that
a treatment (filtration) system will be required for the SVE emissions. However, the emissions from
the full scale SVE system will be tested and a treatment system installed if emission levels exceed
state and federal standards.
Comment: The WDNR "accepts at this time the selection of alternatives as recommended by U.S.
EPA for each source area of concern as identified in National Presto's Remedial Investigation and
Feasibility Study. The Department of Natural Resources does not agree it is in the best interest of
the state's natural resources that the lengthy groundwater restoration periods be accepted....
Additionally, the creation of a permanent disposal site at Melby Road while satisfying the
Department's On-Site and In-State policies does not achieve restoration of the environment.... The
Department accepts U.S. EPA's proposed plan that all areas of concern will be re-evaluated at the
five-year review and subsequent implementation of additional remedies will be undertaken if
conditions so warrant. DNR believes at the five-year review all parties, U.S. EPA, DNR and
National Presto, should evaluate whether it would be cost-effective to implement additional
treatment remedies in the groundwater plumes in lieu of continuing the O&M costs. The viability
of mechanical systems cannot be assumed and additional safeguards to protect public health and the
environment must be sought, if necessary to relieve the lengthy burden proposed by U.S. EPA.
Financial assurances that subsequent restoration action can be taken must be a component of the final
remedy of the site."
U.S. EPA Response: WDNR's comment is further clarified in the December 27,1995 letter from
Jane Lemcke, Superfund Remedial Unit Leader at WDNR, to Wendy Carney, Superfund Remedial
Branch Chief at U.S. EPA. This letter stated that the WDNR did not concur with U.S. EPA's
proposed remedy for the NPI Site. Subsequent discussions between U.S. EPA and WDNR have
resulted in Wisconsin's concurrence with the final remedy for the NPI Site. U.S. EPA believes that
the proposed remedy satisfies the threshold criteria of protecting human health and the environment
and compliance with ARARs. Furthermore, the proposed remedy represents the best balance with
respect to the five "balancing" criteria and two "modifying" criteria. Financial assurances can be
54
-------
sought during negotiations for the Remedial Design and Remedial Action, but play no role in U.S.
EPA's selection of a remedy.
Comments from the Revised Community Relation Plan
Comment: One resident said the current ground-water treatment is a waste of money because the
technology is not addressing the source of the contamination. The resident said remedial activities
should have started with the removal of the contaminated soils and sludges.
U.S. EPA Response: As stated above, the current ground-water treatment systems at the NPI Site
are designed to prevent the off-site migration of contaminated ground water. The air stripper at the
ECMWF currently treats all municipal ground water before its distribution to provide clean drinking
water to the residents of Eau Claire. Recent activities at the NPI Site include the removal of
contaminated soils and sludges from Lagoon No. 1. U.S. EPA traditionally addresses the most
significant threats first at a Superfund site. At NPI, the threat to human health from drinking ground
water was determined to be the most significant. U.S. EPA addressed this threat first by (1)
providing for a bottled water program to affected households; and (2) requiring affected and
potentially affected households to be connected to either the Eau Claire water system (for which U.S.
EPA had earlier constructed an air stripper), or to a new Hallie Sanitary District. U.S. EPA then
required the construction of the on-site pump and treat systems designed to prevent the off-site
migration of contaminated ground water. Once the drinking water threat was addressed, U.S. EPA
turned its attention to the direct contact or inhalation risks posed by on-site materials. Lagoon No.
1 remediation is nearing completion and, with the final remedy, all other known source areas will
be addressed.
•
Comment: Residents were concerned that remedial activities would conflict with a Wisconsin
Department of Transportation (WDOT) project of constructing a bypass for Highway 53 in the area
oftheMelbyRoad
U.S. EPA Response: U.S. EPA does not anticipate that the remedial activities will conflict with the
WDOT project.
Comment: Residents said that they receive information only from U.S. EPA and would like to
receive information from NPI. The community is cautious towards NPI and residents do not know
whom to trust. Residents noted that NPI is jiot providing access to the areas currently under
remediation, not providing site tours and not addressing community relations issues. Because NPI
is not communicating with the public, residents think the company is hiding something.
U.S. EPA Response: The Superfund law does not require NPI to provide site tours and to be more
"community friendly." NPI may not be providing the public access to areas under remediation
because Superfund regulations require specific health and safety requirements for persons entering
the exclusion zones of a Superfund site.
55
-------
Comment: One resident said that NPI profits are up and the company has requested $15 million
from the Army to continue cleanup operations. Some residents remarked that NPI should be paying
for some of the cleanup. They are concerned that NPI is getting a free ride throughout the cleanup
program for contamination the company created. Residents are disappointed that the Army is readily
paying for the cleanup with the taxpayers' money.
U.S. EPA Response: U.S. EPA understands the resident's concerns with respect to the Anny paying
for cleanup. The Army, however, is a potentially responsible party for the NPI Site due to its
involvement at the NPI Site during the years waste forge compound was generated. To date, the
cleanup work has been performed under various agreements between U.S. EPA and NPI. U.S. EPA
has no involvement whatsoever with the agreements through which NPI receives reimbursement
funds for cleanup work from the Army. Finally, NPI has represented to U.S. EPA that it has spent
significant sums of its own funds for cleanup.
Comment: Several residents were concerned that Congress would not reauthorize Superfund and
that would stop or slow NPI remedial activities. Residents were also concerned that U.S. EPA work
at the Site could be interrupted during the Reauthorization process.
U.S. EPA Response: U.S. EPA agrees that all of these concerns are valid.

SUBJECT: Concurrence on the Selected Final Remedy, National Presto
Industries Site, Eau Claire, WI
i
Mf.
Dear Mf. Adantkus:
The Department is providing you with this letter to document our concurrence
with the remedy selected for the final actions at the National Presto
Industries (NPI) Superfund site. The final remedy, as described in the draft
Record of Decision, will address the remaining source control and groundwater
cleanup needed, and is considered the final remedy for the NPI at the site.
The selected remedy is alternative M-B1, D-B, W-B, GW1-A, GW3-A and GW5-A,
which include:
- Soil Vapor Extraction at the Nelby Road disposal site, with hot spot
excavation and disposal as needed, and soil gas monitoring;
• Consolidation of Wastes at the Melby Road Disposal site, with
excavation from the East Disposal Site and Drainage Ditch 3;
- Construction of a Multi -Layer /NR 660 Cap at the Nelby Road Disposal
Site, with long term groundwater monitoring and deed restrictions to
limit land use from disturbing the cap integrity;
- Long Term Qroundwater Monitoring at plumes 1-2 and 3, 4 and 5;
- Contingency for further actions if necessary at plumes 1-2; and
- Surface Water Monitoring in Lake Hal lie, downgradient of Plumes 3, 4
and 5.
The costs for the selected remedy are estimated to be as follows:
Capital Cost $3.274 M
Annual O&M First Year $261,000
Total Present Worth $6.542 M
We understand that if the potentially responsible parties (PRPs) do not agree
to fund the remedy, it will be necessary for the State of Wisconsin to
contribute 10% of the remedial action costs associated with the actions
and 10% of the O&M costs for the first 10 years of groundwater extraction and
treatment, and provide for all O6M after that, provided that no changes to the
Quality Natural Resources Management
Through Excellent Customer Service
-------
National Contingency Plan are made that would require an alternative cost
allocation. We provide assurance of the State's willingness to provide this
required state cost share on the assumption that U. S. EPA will pursue all
feasible enforcement actions against the PRPs prior to expending the Fund at
the site.
We understand that if the Fund is expended to conduct the remedy and if
hazardous waste needing disposal is required to be managed off-site as part of
the remedy, that the State of Wisconsin will be required to provide the
assurances for hazardous waste management in §40 CFR 300.510 (d) and (e) of the
National Contingency Plan. The assurances are that a compliant hazardous
waste facility is available, and that facility's use is consistent with our
approved Capacity Assurance Plan.
We also understand that our staff will continue to work in close consultation
with your staff during the pre-design, design and construction phases of the
remedy.
Thank you for your support and cooperation in addressing the contamination
problem at the NPI site. Should you have any questions regarding this matter,
please contact Jane Lemcke, Superfund Remedial Unit Leader, at (608) 267-0554.
