National Oil and Hazardous Substance Pollution Contingency Plan;
National Priorities List: Deletion of the Eau Claire Municipal Well
Field Superfund Site
AGENCY: Environmental Protection Agency.
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: The U.S. Environmental Protection Agency (EPA) Region 5 is
publishing a direct final notice of deletion of the Eau Claire
Municipal Well Field Superfund Site (Site) located in Eau Claire,
Wisconsin, from the National Priorities List (NPL). The NPL,
promulgated pursuant to Section 105 of the Comprehensive Environmental
Response, Compensation, and Liability Act (CERCLA) of 1980, as amended,
is an appendix to the National Oil and Hazardous Substances Pollution
Contingency Plan (NCP). This direct final deletion is being published
by EPA with the concurrence of the State of Wisconsin, through the
Wisconsin Department of Natural Resources (WDNR), because EPA has
determined that all appropriate response actions under CERCLA have been
completed. However, this deletion does not preclude future actions
under Superfund.
DATES: This direct final deletion is effective May 27, 2014 unless EPA
receives adverse comments by April 28, 2014. If adverse comments are
received, EPA will publish a timely withdrawal of the direct final
deletion in the Federal Register informing the public that the deletion
will not take effect.

V. Deletion Action
I. Introduction
EPA Region 5 is publishing this Direct Final Notice of Deletion of
the Eau Claire Municipal Well Field Superfund Site from the National
Priorities List (NPL) and requests public comments on this proposed
action. The NPL constitutes Appendix B of 40 CFR part 300, which is the
National Oil and Hazardous Substances Pollution Contingency Plan (NCP),
which EPA promulgated pursuant to Section 105 of the Comprehensive
Environmental Response, Compensation and Liability Act (CERCLA) of
1980, as amended. EPA maintains the NPL as the list of sites that
appear to present a significant risk to public health, welfare, or the
environment. Sites on the NPL may be the subject of remedial actions
financed by the Hazardous Substance Superfund (Fund). This deletion of
the Eau Claire Municipal Well Field Superfund Site is proposed in
accordance with 40 CFR 300.425(e) and is consistent with the Notice of
Policy Change: Deletion of Sites on the National Priorities List, (49
FR 37070), 09/21/1984. As described in 300.425(e) (3) of the NCP, sites
deleted from the NPL remain eligible for Fund-financed remedial actions
if future conditions warrant such actions.
Because EPA considers this action to be noncontroversial and
routine, this action will be effective May 27, 2014 unless EPA receives
adverse comments by April 28, 2014. Along with this Direct Final Notice
of Deletion, EPA is co-publishing a Notice of Intent to Delete in the
``Proposed Rules'' section of the Federal Register. If adverse comments
are received within the 30-day public comment period on this deletion
action, EPA will publish a timely withdrawal of this direct final
Notice of Deletion before the effective date of the deletion, and the
deletion will not take effect. EPA will, as appropriate, prepare a
response to comments and continue with the deletion process on the
basis of the Notice of Intent to Delete and the comments already
received. There will be no additional opportunity to comment.
Section II of this document explains the criteria for deleting
sites from the NPL. Section III discusses procedures that EPA is using
for this action. Section IV discusses the Eau Claire Municipal Well
Field Site and demonstrates how it meets the deletion criteria. Section
V discusses EPA's action to delete the site from the NPL unless adverse
comments are received during the public comment period.
II. NPL Deletion Criteria
The NCP establishes the criteria that EPA uses to delete sites from
the NPL. In accordance with 40 CFR 300.425(e), sites may be deleted
from the NPL where no further response is appropriate. In making such a
determination pursuant to 40 CFR 300.425(e), EPA will consider, in
consultation with the State, whether any of the following criteria have
been met:
i. Responsible parties or other persons have implemented all
appropriate response actions required;
ii. All appropriate Fund-financed response under CERCLA has been
implemented, and no further response action by responsible parties is
appropriate; or
iii. The remedial investigation has shown that the release poses no
significant threat to public health or the environment and, therefore,
the taking of remedial measures is not appropriate.
Pursuant to CERCLA Section 121(c) and the NCP, EPA conducts five-
year reviews to ensure the continued protectiveness of remedial actions
where hazardous substances, pollutants, or contaminants remain at a
site above levels that allow for unlimited use and unrestricted
exposure. EPA may conduct such five-year reviews even if a site is
deleted from the NPL. EPA may initiate further action to ensure
continued protectiveness at a deleted site if new information becomes
available that indicates it is appropriate. Whenever there is a
significant release from a site deleted from the NPL, the deleted site
may be restored to the NPL without application of the hazard ranking
system.
III. Deletion Procedures
The following procedures apply to deletion of the Eau Claire
Municipal Well Field Site:
(1) EPA consulted with the State of Wisconsin prior to developing
this direct final Notice of Deletion and the Notice of Intent to Delete
co-published today in the ``Proposed Rules'' section of the Federal
Register.
(2) EPA has provided the State thirty (30) working days for review
of this notice and the parallel Notice of Intent to Delete prior to
their publication today, and the State, through the WDNR, has concurred
on the deletion of the Site from the NPL.
(3) Concurrently with the publication of this direct final Notice
of Deletion, a notice of the availability of the parallel Notice of
Intent to Delete is being published in a major local newspaper, ``Eau
Claire Leader Telegram''. The newspaper notice announces the 30-day
public comment period concerning the Notice of Intent to Delete the
Site from the NPL.
(4) EPA placed copies of documents supporting the proposed deletion
in the deletion docket and made these items available for public
inspection and copying at the Site information repositories identified
above.
(5) If adverse comments are received within the 30-day public
comment period on this deletion action, EPA will publish a timely
notice of withdrawal of this direct final Notice of Deletion before its
effective date and will prepare a response to comments and continue
with the deletion process on the basis of the Notice of Intent to
Delete and the comments already received.
Deletion of a site from the NPL does not itself create, alter, or
revoke any individual's rights or obligations. Deletion of a site from
the NPL does not
[[Page 17443]]
in any way alter EPA's right to take enforcement actions, as
appropriate. The NPL is designed primarily for informational purposes
and to assist EPA management. Section 300.425(e)(3) of the NCP states
that the deletion of a site from the NPL does not preclude eligibility
for future response actions, should future conditions warrant such
actions.
IV. Basis for Site Deletion
The following information provides EPA's rationale for deleting the
Eau Claire Municipal Well Field Superfund Site from the NPL.
Site Background and History
The Eau Claire Municipal Well Field (ECMWF) site (CERCLIS ID:
WID980820054) is located in Chippewa County in the Chippewa River
Valley, east of the Chippewa River and approximately 2.5 miles west of
the National Presto Industries (NPI) site. The ECMWF site consists of
15 municipal groundwater wells in two adjoining well fields (five in
the north well field and ten in the south) that provide drinking water
to approximately 60,000 residential and commercial users. All municipal
wells are installed in the glacial outwash sand and gravel aquifer. In
addition to these municipal wells, a number of private wells previously
drew drinking water from this sand and gravel aquifer. The sand and
gravel aquifer is hydraulically connected to an underlying sandstone
aquifer, which is not used extensively in the area due to its low
hydraulic conductivity and the water's poor aesthetic qualities. The
well field is about a mile long and trends generally in a north-south
direction. The ECMWF site has been used as a well field by the city for
over the past 70 years. According to city personnel, prior to that time
it was forested land. Current land use in the surrounding area is
primarily residential, with a small park to the south and the Eau
Claire airport located about one-quarter mile east of the northern
portion of the city well field. It is anticipated that these land uses
will continue into the foreseeable future.
In March 1981, as part of the U.S. EPA Groundwater Supply Survey,
the WDNR tested the Eau Claire municipal water supply for volatile
organic compounds (VOCs). Trichloroethene (TCE), 1,1-dichloroethene
(1,1-DCE), 1,1-dichloroethane (1,1-DCA), and 1,1,1-trichloroethane
(1,1,1-TCA) were detected in samples collected from the north well
field. The WDNR informed the city of Eau Claire that the concentrations
for each of the VOCs detected were below Wisconsin groundwater
standards. In addition to monitoring individual municipal production
wells, the city began testing private residential wells located
immediately northeast of the well field. VOCs were subsequently
detected in several of the residential wells sampled at levels above
Wisconsin groundwater standards.
Remedial Investigation and Feasibility Study
EPA initiated a Remedial Investigation/Feasibility Study (RI/FS) at
the ECMWF site in October 1984. Based on groundwater monitoring data
from private wells and monitoring wells installed as part of the field
investigation, the ECMWF RI identified two distinct plumes of
contamination at the site, separated by a gap of approximately 1,700
feet at the Eau Claire County Airport. The ECMWF RI did not confirm the
source of the groundwater contamination at the well field but suggested
that the nearby National Presto Industries (NPI) property (which later
became a Superfund site) could be a potential source of the groundwater
contamination at the ECMWF site. Data generated during the NPI RI
clearly established that waste disposal areas at the NPI site were the
source of TCE contamination at the ECMWF site, and indeed, continued to
release contaminants to groundwater. A separate action was taken at NPI
and cleanup at the NPI site is still ongoing.
Record of Decision Findings
On June 10, 1985, EPA issued a Record of Decision (ROD) that
selected a packed column air stripper as an Initial Remedial Measure
(IRM) to address contamination at the ECMWF site. During the first
month of operation (August 1987), influent to the air strippers was
sampled and analyzed weekly for VOCs. Influent and effluent have been
tested monthly thereafter. Influent and effluent samples are analyzed
for VOCs according to modified Method 601 of 40 CFR part 136 by the
city of Eau Claire.
Following the completion of the RI/FS, EPA issued the final ROD for
the ECMWF site on March 31, 1988. The major components of the selected
remedy were:
Continued treatment of contaminated municipal water with
the air stripper constructed as the IRM;
provision of municipal water from the city of Eau Claire
to private well users within or near the two plumes of groundwater
contamination identified during the RI;
installation of groundwater extraction wells in one of the
two plumes of contamination; and
discharge of untreated groundwater from extraction wells
to the Chippewa River. WDNR concurred with the remedy selected by EPA
for the ECMWF site. The remedies for the ECMWF site were developed to
meet the following Remedial Action Objectives (RAOs):
Prevent human ingestion of contaminated groundwater,
Prevent inhalation of contaminants from the groundwater,
and
Restore the contaminated aquifer to water quality
objectives that are protective of beneficial use within a reasonable
timeframe.
Explanation of Significant Differences
After EPA issued the ECMWF site final ROD, WDNR determined that the
discharge of untreated groundwater from the proposed extraction wells
into the Chippewa River would not comply with Wisconsin Statute,
Chapter 283, Pollution Discharge Elimination. As a result, two of the
components of the ECMWF site remedy, installation of extraction wells
and the discharge of untreated water, were never fully implemented. The
lack of extraction wells, however, did not fundamentally alter the
selected ECMWF remedy. EPA issued an Explanation of Significant
Differences (ESD) in 2008 to document that these measures were not
implemented and would not be implemented in the future.
The 1988 ROD states that ``EPA will clean up the groundwater to
non-detect for these compounds and continue to pump and treat for a
period of time beyond the non-detect to assure that the target compound
limits (TCLs) have been reached.'' The target cumulative carcinogenic
risk for the site was set at 1 x 10-6 excess lifetime cancer
risk (ELCR) and apportioned across several of the site's VOC
groundwater contaminants. In order to provide the desired
protectiveness, the TCLs needed to be lower than federal drinking water
standards (maximum contaminant levels (MCLs) under the Safe Drinking
Water Act (SDWA)).
EPA and WDNR reviewed the cleanup goals upon conclusion of the 2007
Five-Year Review. The 1988 ROD had developed TCLs as groundwater
cleanup goals at the ECMWF site. However, in 1985 Wisconsin had
promulgated Groundwater Quality regulations in the Wisconsin
Administrative Code (WAC), Chapter 140 (NR 140). An ESD was signed on
December 23, 2009, to update the groundwater cleanup goals to
incorporate NR 140. NR 140 provides
[[Page 17444]]
two types of standards that are to be followed. One is the Preventive
Action Limits (PALs) and the other is the Enforcement Standards (ES).
WDNR concurred with the ESD which adopted enforcement standards as the
groundwater cleanup goal.
Construction Activities
On behalf of EPA, the U.S. Army Corps of Engineers completed
construction of the air stripper in June 1987 and the system became
operational in August 1987. The city of Eau Claire operates the air
stripper as a part of its drinking water distribution operations. The
air stripper has been in constant operation since completion of the
interim remedial action in 1987. A permanent municipal water supply has
been provided to affected private well owners in the city of Eau
Claire, and a permanent municipal water supply was constructed and is
operating in the Town of Hallie which provides its residents with
drinking water.
On April 25, 1989, EPA issued a Section 106 Administrative Order to
the NPI PRPs to execute remedial action tasks consistent with the ECMWF
final ROD and the data generated in the NPI RI. These activities
included implementation of a temporary bottled water distribution
program for those in the affected area in and adjacent to the redefined
Plume 2. NPI was also required to conduct a Phased Feasibility Study
(PFS) to identify and reevaluate options for a permanent alternate
drinking water supply for the affected area. To ensure consistency with
the ECMWF final ROD, bottled water was to be made available to all
private well users in the affected area until a permanent and
uncontaminated drinking water supply was fully implemented and
operational.
On August 1, 1990, EPA issued a ROD for the NPI site selecting a
permanent drinking water supply for the affected area in and around the
redefined Plume 2. Under this ROD, the city of Eau Claire would extend
its municipal service to those portions of the affected area which had
been annexed to the city. The remaining portions of the affected area
were to be serviced by a newly created Hallie Sanitary District
(District).
The city of Eau Claire hookups were completed by November 1991. The
first service connections to the District were completed in December
1991 and by mid-summer 1992 the District was fully operational and
servicing the affected area within the Town of Hallie.
EPA conducted a pre-certification inspection of the District on
August 19, 1992. Upon completion of the certification process by the
Agency and satisfaction of the terms of the Administrative Order, the
District assumed full control and responsibility, including operation
and maintenance, of its drinking water system.
Remediation of off-site groundwater, including Plume 1-2 which
migrated from the NPI site to the ECMWF site, was addressed in the
final FS for the NPI site in conjunction with remediation of on-site
source areas in the southwest corner of the NPI site. NPI also
implemented an interim action for on-site plume containment pursuant to
a third Section 106 Administrative Order issued to NPI on July 2, 1992.
This action was designed to be consistent with the final cleanup action
for the NPI site by preventing the off-site movement of contaminated
groundwater through extraction and treatment. This alternative was
selected in an Interim Action ROD issued for the NPI site by EPA on
September 30, 1992.
The city of Eau Claire has annexed and extended municipal water
service to private well owners in the area that could have been subject
to impacts from the contaminated groundwater originating from the NPI
site. NPI paid for the construction of two air stripping towers at the
ECMWF and continues to pay for their operation. The purpose of the
towers is to remove the very low concentrations, even below federal
drinking water standards, of volatile organic compounds in the
groundwater withdrawn by the city wells and to ensure a safe drinking
water supply for the city. These engineered controls appear to be
effective in their goal of protecting human health and the environment.
Institutional Controls
Institutional Controls (ICs) were required at the ECMWF site in
order to ensure the protectiveness of the remedy. ICs are non-
engineered instruments, such as administrative and/or legal controls,
that help minimize the potential for exposure to contamination and
protect the integrity of the remedy. Compliance with ICs is required to
assure long-term protectiveness for any areas that do not allow for
unlimited use or unrestricted exposure (UU/UE).
The ROD for the ECMWF site did not identify the need for ICs.
However, the 1996 ROD for NPI acknowledges that ICs are required to
ensure protectiveness of the final site-wide remedy until Plume 1-2,
which impacts the ECMWF, meets the groundwater cleanup goals.
Residences in the affected area who have received municipal water are
still 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 private wells, property owners must submit
applications for annual permits to either the City of Eau Claire's
Health Department or the Hallie Sanitary District.
The City of Eau Claire (City), Village of Lake Hallie (formerly
known as the Town of Hallie), and Chippewa County have all passed
ordinances to protect citizens from impacted groundwater. The City has
an ordinance that bans cross connections between private water supply
wells and the municipal supply. The City has also annexed properties
that are within and near the identified boundaries of the NPI plume(s)
in Chippewa County and provided those properties with municipal water.
The City recently enacted an ordinance that restricts the construction
of new private water supply wells within the City, as well as requiring
the abandonment of existing supply wells. The WDNR has promulgated
Chapters NR 809 and NR 811 of the Wisconsin Administrative Code, which
regulate safe drinking water and the design and operation of municipal
water systems, respectively. The key part of this code, as it pertains
to ECMWF site, is its prohibition against cross connections and its
requirement of adequate separation of potable wells from sources of
contamination.
The ordinances and administrative codes enacted by the local
municipalities, counties, and the state provide a strong and effective
framework for protection of the local citizens against consumption of
contaminated groundwater from NPI and ECMWF until the cleanup goals are
attained in all plumes.
Cleanup Goals
Recent data indicates that the levels of TCE in Plume 1-2 have
declined and are meeting the Wisconsin enforcement standard of 5 ppb,
except for 5 groundwater monitoring wells associated with the NPI site,
which exceed the enforcement standard. One of these groundwater
monitoring wells is located on the NPI site property and is
significantly above the enforcement standard; two groundwater
monitoring wells are west of the NPI site along North Hastings Way and
measures TCE between 5-6 ppb; and two groundwater monitoring wells
located at and near the airport measure TCE between 5-6 ppb.
Groundwater monitoring wells on the ECMWF site, as well as the
production wells, all show TCE below the enforcement standard of 5 ppb.
A review of the monthly production well data by ECMWF for wells 10, 11,
15, 16, 17 and 19 shows that the TCE has not been detected except for
well 19. This
[[Page 17445]]
well does detect TCE consistently, but it is below the enforcement
standard of 5 ppb. The blended production well water entering the air
stripper is non-detect for any VOCs. The detection limit used by the
city in its analyses is 0.7 ppb TCE. As a result, the implemented
remedy at the ECMWF site has achieved the degree of cleanup as
specified in the decision documents for all pathways of exposure.
Operation and Maintenance
Operation and maintenance (O&M) requirements outlined in the O&M
Plan for the IRM were: (1) Routine maintenance of the air stripper as
described in the manufacturer's manual; and (2) sampling and analysis
requirements of stripper influent and effluent, as previously
discussed. TCE, 1,1-DCE, 1,1-DCA, 1,1,1-TCA and tetrachloroethene (PCE)
are monitored regularly by the city of Eau Claire to ensure compliance
with Wisconsin Enforcement Standards and the Safe Drinking Water Act
Maximum Contaminant Limits (MCLs) for drinking water.
Five-Year Review
EPA conducted four five-year reviews at this site; the last report
was dated July 17, 2012. EPA, in consultation with the Wisconsin
Department of Natural Resources (WDNR), determined that the cleanup
remedy at the ECMWF site is protective of human health and the
environment because cleanup standards have been met at the site.
Additionally, exposure pathways from the NPI site that could result in
unacceptable risks are being controlled through the use of ICs. EPA has
also determined that the air strippers at ECMWF can be taken off-line
as the groundwater entering the city's well field has met the cleanup
standards for over 5 years and is not expected to exceed the standards
in the future. The city of Eau Claire has chosen to keep the air
strippers on-line in the short term, although they may turn off the air
strippers at a future date. Since unlimited use/unrestricted exposure
has been met at the ECMWF site, future five-year reviews are not
required.
Community Involvement
Public participation activities have been satisfied as required in
CERCLA Section 113(k), 42 U.S.C. 9613(k), and CERCLA section 117, 42
U.S.C. 9617. Documents in the deletion docket which EPA relied on for
recommendation of the deletion of this site from the NPL are available
to the public in the information repositories and at
www.regulations.gov.
Determination That the Site Meets the Criteria for Deletion in the NCP
The NCP (40 CFR 300.425(e)) states that a site may be deleted from
the NPL when no further response action is appropriate. EPA, in
consultation with the State of Wisconsin, has determined that all
required response actions have been implemented and no further response
action by the responsible parties is appropriate.
V. Deletion Action
EPA, with concurrence from the State of Wisconsin through the WDNR,
has determined that all appropriate response actions under CERCLA have
been completed. Therefore, EPA is deleting the Site from the NPL.
Because EPA considers this action to be noncontroversial and
routine, EPA is taking it without prior publication. This action will
be effective May 27, 2014 unless EPA receives adverse comments by April
28, 2014. If adverse comments are received during the comment period,
EPA will publish a timely withdrawal of this direct final Notice of
Deletion before the effective date of the deletion, and it will not
take effect. EPA will prepare a response to comments and continue with
the deletion process on the basis of the notice of intent to delete and
the comments already received. There will be no additional opportunity
to comment.
