ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 300
[FRL-5845-5]
National Oil and Hazardous Substances Pollution Contingency Plan;
National Priorities List
AGENCY: Environmental Protection Agency.
ACTION: Notice of intent to delete the Agate Lake Scrap Yard Site from
the National Priorities List; request for comments.
-----------------------------------------------------------------------
SUMMARY: The United States Environmental Protection Agency (EPA) Region
V announces its intent to delete the Agate Lake Scrap Yard Site (the
Site) from the National Priorities List (NPL) and requests public
comment on this action. The NPL constitutes Appendix B to 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 of 1980
(CERCLA) as amended. This action is being taken by EPA, because it has
been determined that all Fund-financed responses under CERCLA have been
implemented and EPA, in consultation with the State of Minnesota, has
determined that no further response is appropriate. Moreover, EPA and
the State have determined that remedial activities conducted at the
Site to date have been protective of public health, welfare, and the
environment.
DATES: Comments concerning the proposed deletion of the Site from the
NPL may be submitted on or before July 23, 1997.
ADDRESSES: Comments may be mailed to Gladys Beard, Associate Remedial
Project Manager, Superfund Division, U.S. EPA, Region V, 77 W. Jackson
Blvd. (SR-6J), Chicago, IL 60604. Comprehensive information on the site
is available at U.S. EPA's Region V office and at the local information
repository located at: Brainerd Public Library, 416 South 5th South
Street, Brainerd, MN 56401. Requests for comprehensive copies of
documents should be directed formally to the Region V Docket Office.
The address and phone number for the Regional Docket Officer is Jan
Pfundheller (H-7J), U.S. EPA, Region V, 77 W. Jackson Blvd., Chicago,
IL 60604, (312) 353-5821.

I. Introduction
The U.S. Environmental Protection Agency, Region V announces its
intent to delete the Agate Lake Scrap Yard Site from the National
Priorities List (NPL), which constitutes Appendix B of the National Oil
and Hazardous Substances Pollution Contingency Plan (NCP), and requests
comments on the proposed deletion. The EPA identifies sites that appear
to present a significant risk to public health, welfare or the
environment, and maintains the NPL as the list of those sites. Sites on
the NPL may be the subject of remedial actions financed by the
Potentially Responsible Parties or the Hazardous Substance Superfund
Response Trust Fund (Fund). Pursuant to section 300.425(e)(3) of the
NCP, any site deleted from the NPL remains eligible for Fund-financed
remedial actions if the conditions at the Site warrant such action.
The EPA will accept comments on this proposal for thirty (30) days
after publication of this notice in the Federal Register.
Section II of this notice explains the criteria for deleting sites
from the NPL. Section III discusses procedures that EPA is using for
this action. Section IV discusses the history of this site and explains
how the Site meets the deletion criteria.
Deletion of sites from the NPL does not itself create, alter, or
revoke any individual's rights or obligations. Furthermore, deletion
from the NPL does not in any way alter EPA's right to take enforcement
actions, as appropriate. The NPL is designed primarily for
informational purposes and to assist in Agency management.
II. NPL Deletion Criteria
The NCP establishes the criteria that the Agency 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 this determination, 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; or
(ii) All appropriate Fund-financed responses under CERCLA have 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, remedial measures are not appropriate.
III. Deletion Procedures
Upon determination that at least one of the criteria described in
section 300.425(e) has been met, EPA may formally begin deletion
procedures once the State has concurred. This Federal Register
document, and a concurrent document in the local newspaper in the
vicinity of the Site, announce the initiation of a 30-day comment
period. The public is asked to comment on EPA's intention to delete the
Site from the NPL. All critical documents needed to evaluate EPA's
decision are included in the information repository and the deletion
docket.
Upon completion of the public comment period, if necessary, the EPA
Regional Office will prepare a Responsiveness Summary to evaluate and
address comments that were received. The public is welcome to contact
the EPA Region V Office to obtain a copy of this responsiveness
summary, if one is prepared. If EPA then determines the deletion from
the NPL is appropriate, final notice of deletion will be published in
the Federal Register.
IV. Basis for Intended Site Deletion
The Agate Lake Scrap Yard Site is located in Fairview Township,
Cass County, Minnesota, on the southwest shore of Agate Lake. Agate
Lake is an estimated one half mile west of Gull
[[Page 33790]]
Lake, which is located approximately 15 miles northwest of the city of
Brainerd.
The Site is approximately eight acres in size, and is located on
land surrounded on three sides by either open water or wetlands. This
peninsular land, which rises approximately ten feet above the
surrounding water level, is composed of sandy glacial deposits, which
extend to a depth of 200 feet or more. There are thin lenses of gravel
and clay interspersed in the top 100 feet of the soil profile.
In 1952, Mr. Paul Kramer established a scrap yard on the farmland
owned by his mother which consisted of buying and selling scrap yard
materials such as white goods, scrap iron and metal and used cars.
During the 1970's the scrap included drums of solvents and various
oils, along with a large number of transformers of which the oils were
used in a smelter and a homemade burner. In the smelter, he recovered
aluminum and lead by melting and pouring these molten metals into
molds. He also recovered copper by burning the insulation off copper
wire. The scrap yard was operated until the end of 1982. The Minnesota
Pollution Control Agency (MPCA) staff ordered Mr. Kramer to cease
moving, draining or burning any oils, transformers, transformer cases,
drums, ashes or soil, until all necessary testing for polychlorinated
biphenyls (PCBs) had been completed.
According to Mr. Kramer, he obtained the pole-mounted transformers
from the Crow Wing Cooperative Power and Light Company (Crow Wing Coop)
in Brainerd, and the large transformers from the Burlington Northern
Railroad Company (BNRR), also of Brainerd.
The Site was proposed for the Federal National Priorities (NPL) on
October 15, 1984. The listing was finalized on June 10, 1986.
In January 1983, BNRR removed from the Site part of the
transformers including oils and drums attributed to BNRR. Also in 1983,
Crow Wing Coop hired a contractor to remove the remaining transformers
from the Site, and to clean up the Agate Lake Site. Approximately six
inches of topsoil were removed in the areas where the transformers had
been located around the smelter and burner, and where scrap yard
operations had taken place. The removed topsoil was placed in a gully
on the property, identified as a microbiological cell suggesting that
biological degradation of PCBs and oils would occur. Areas where soils
had been removed were back filled with clean topsoil, and then seeded
with rye.
In September 1985, MPCA under the Multi-Site Cooperative Agreement
with Superfund performed a Remedial Investigation (RI) Feasibility
Study (FS) at the Site.
On January 28, 1996, MPCA issued a Request For Response Action
(RFRA) to BNRR, Crow Wing Coop and to Mr. Paul Kramer to complete the
RI/FS as well as prepare and implement a Response Action Plan (RAP).
In January 1987, the Responsible Parties (RPs), completed the RI
and a limited site cleanup by removing large quantities of solid waste
and scrap metal. At the request of EPA, additional remedial
investigations were undertaken during 1991 and 1992.
Based upon the findings of the RI/FS, the EPA and MPCA recommended
the following: removal of 260 tons of lead-contaminated ash, slag and
soils; removal of 200 tons of soils contaminated with polychlorinated
biphenyls (PCBs); removal of 3 cubic yards of pipe insulation
containing asbestos and regular groundwater monitoring of shallow and
deep ground water at the Site, as well as a deed restriction that
prohibits well installation in the area in which groundwater
contamination has been found. The groundwater does not discharge to
surface water therefore there is no impact on the surrounding lakes.
In September 1992 and May 1993, the MPCA issued Interim Response
Actions (IRAs) to address all the contaimination identified in the RI/
FS's with the exception of groundwater contamination and deed
restrictions.
In January of 1994 a Record of Decision (ROD) was issued to address
the remaining cleanup. The remedy selected in the ROD involves the
long-term monitoring of the shallow sand aquifer at the Site, by means
of existing monitoring wells. The ROD also requires the installment of
four additional wells in selected locations and institutes specific
deed restrictions to a portion of the property whereby no drinking
wells would be allowed to be installed in the area of contaiminated
groundwater. The long-term monitoring also serves to document the
process of natural attenuation which addresses the remaining low levels
of perchloroethene (PCE) present in groundwater at the Site.
On March 5, 1997, Environmental Protection Agency Contractors,
Conestoga-Rovers and Associates (CRA), submitted their Annual Report in
accordance with the FS dated February 26, 1993. The report stated that
in October 1996, analytical results show, only two wells exhibited
concentrations of PCE. These wells include observance well OW6 and OW7.
Although monitoring OW4 showed PCE concentrations of 4.8 g/L
in April 1996, no detections were present during the October 1996
event. The PCE concentrations at OW6 were 6 g/L, which is
below the Health Risk Limit (HRL) of 7 g/L. PCE concentrations
at OW6 have shown a steady decrease since January 1992, and this is the
first time PCE concentrations at OW6 have been below the HRL since a
sample round in October 1986 showed no detections. The PCE
concentrations at OW7 in October 1997 were 3.6 g/L. This
further supports the conclusion that there is not a significant source
of PCE impacting the groundwater and that the effects of natural
attenuation has reduced the PCE concentrations.
All activities have been completed at the Site. The final
inspection took place on November 30, 1994, during which the several
items needed attention. The RPs agreed to complete the items
identified. The Final Remedial Completion Report was approved by MPCA
on February 2, 1995, thereby initiating Site removal from the NPL. All
the HRLs has been met at the entire site, therefore the natural
attenuation has provided protection of human health and the
environment.
A five-year review pursuant to OSWER Directive 9355.7-02
(``Structure and Components of Five-Year Reviews'') will be conducted
at the Site. The five-year review is schedule for September 1999.
EPA, with concurrence from the State of Minnesota, has determined
that all appropriate Fund-financed responses under CERCLA at the Agate
Lake Scrap Yard Site have been completed, and no further CERCLA
response actions are appropriate in order to provide protection of
human health and environment. Therefore, EPA proposes to delete the
Site from the NPL.
Dated: June 12, 1997.
