I. Introduction
The U.S. Environmental Protection Agency (EPA) Region V announces
its intent to delete the Kummer Sanitary Landfill 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 may 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
Hazardous Substance Superfund Response Trust Fund (Fund) or by
responsible parties. 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 U.S. 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 U.S. 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 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, U.S. 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.
[[Page 8013]]
III. Deletion Procedures
Upon determination that at least one of the criteria described in
300.425(e) has been met, U.S. EPA may formally begin deletion
procedures once the State has concurred. This Federal Register notice,
and a concurrent notice 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 U.S. EPA's intention to delete the Site from the
NPL. All critical documents needed to evaluate U.S. EPA's decision are
included in the information repository and the deletion docket.
Upon completion of the public comment period, if necessary, the
U.S. EPA Regional Office will prepare a Responsiveness Summary to
evaluate and address comments that were received. The public is welcome
to contact the U.S. EPA Region V Office to obtain a copy of this
responsiveness summary, if one is prepared. If U.S. 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 Kummer Landfill Sanitary is located in Northern Township,
Beltrami County, Minnesota and borders the city of Bemidji. The
Northern township has an estimated population of 3,997 in 1993 and
contains a large mobile home park which is located east and southeast
of the Site. The Kummer Landfill waste occupies approximately 23 acres
in the southern portion of the township and is about 750 feet from the
nearest residence. The landfill is situated above a shallow surficial
sand aquifer which serves as a primary source of drinking water for the
area.
In June 1984, the Site was placed on the National Priorities List
(NPL), Federal Register 51 page 21071.
On September 29, 1984, the U. S. EPA and MPCA executed a
Cooperative Agreement for implementing a Remedial Investigation/
Feasibility Study (RI/FS). Following the discovery of ground water
contamination, a Determination of Emergency was issued by the MPCA on
July 17, 1984. This permitted the expenditure of State Superfund money
for a temporary water supply for affected residents. The Minnesota
Department of Health (MDH) and MPCA delineated a three and one-half
block area east of the landfill as a well advisory area. On August 28,
1994, the MPCA authorized the expenditure of State Superfund money for
a focused FS on a water system for the advisory area. Eighty-one
property owners received letters from MDH on August 29, 1984, which
notified them that they should discontinue the use of their private
wells for drinking and cooking purposes.
Because of the complexity of work at the Kummer Sanitary Landfill,
the activities at the site have been divided into three operable units,
which are:
Operable Unit 1. Northern Township Municipal Water System
Operable Unit 2. Source Control of contaminants emanating from the
landfill
Operable Unit 3. Management of the contaminated ground water
On June 12, 1985, a Record of Decision (ROD) for Operable Unit 1
was signed which selected an alternative water supply as the remedial
action. The selected remedy provided for an extension of the existing
public water supply from the city of Bemidji. Construction of the water
system began in June 1987, and was completed in the summer of 1990. A
total of 198 connections to individual homes, businesses, and a mobile
home park were completed in operable unit one.
Due to the complexity of the site, the RI investigation was
completed in phases. The Final RI Report was approved in May 1990. The
Source Control Operable Unit (Operable Unit 2) FS was completed in
September 1988. On September 30, 1988, a second ROD was signed which
selected a cover system for the landfill as the remedial action for
Operable Unit 2. The selected remedy included a low permeability cap,
site deed restrictions, fencing and long-term operation and maintenance
to provide inspections and repairs to the cap. The Construction of the
cap was completed in October 1991.
The Ground Water Operable unit (Operable Unit 3) RI/FS was
completed in July, 1990. Three ground water monitoring programs were
completed, and eight rounds of data were collected. The results
revealed that VOCs were being introduced into the shallow ground water
by the landfill. However, ground water monitoring has shown that the
plume does not extend to Lake Bemidji.
On September 29, 1990, a third ROD was signed which selected a
remedy that included ground water extraction for an estimated period of
30 years, during which the system's performance would be carefully
monitored on a regular basis and adjusted as warranted by the
performance data collected during operation.
On November 21, 1995, a ROD Amendment was signed concerning the
ground water Operable unit (OU3). The remedy selected was
bioremediation which provides no exposure of contaminated ground water
to potential receptors. The major components of the amended remedy for
OU3 include:
Installation of a pilot scale field demonstration to
determine the feasibility of insitu biodegradation of the chemicals of
concern;
Installation of a full scale insitu bioremediation system
after one year of operation of the pilot scale field demonstration if
necessary to meet the Maximum Contaminant Level (MCL) for chemicals of
concern located in ground water;
Long term monitoring of ground water to verify that the
concentrations of the chemicals of concern are continuing to decline
and to measure performance of the pilot scale field demonstration and
or full scale insitu bioremediation system;
Continued observance of the Minnesota Health Department
Well Advisory which regulates the location of future potable wells near
the Site;
Institutional Controls in the form of Site access
restrictions that protect the remedy; and operation and maintenance of
the remedy, including periodic inspection of the Site.
The public accepted the remedy in the 1990 OU3 ROD. A public
information meeting was held by the State of Minnesota on June 5, 1995,
in Northern Township to inform interested parties on the amend remedy
and the State 's desire to amend the 1990 ROD. There were no strong
comments against the change in the remedy.
In 1994, the Legislature of the State of Minnesota enacted the
Landfill Cleanup Law, Minn. Laws 1994, ch. 639, codified at Minn. Stat.
Sec. Sec. 115B.39 to 115B.46 (the Act), authorizing the Commissioner of
the Minnesota Pollution Control Agency (MPCA) to assume responsibility
for future environmental response actions at qualified landfills that
have received notices of compliance from the Commissioner of MPCA.
Additionally, the Act established funds to enable the MPCA to perform
all necessary response, operation and maintenance at such landfills. At
sites where no responsible parties are conducting response actions
under CERCLA, MPCA is responsible for issuing a notice of compliance,
after it determines that all work that could be expected under a state
order or under state closure requirements has been completed.
A notice of compliance was issued by MPCA for the Kummer Sanitary
Landfill Site on November 7, 1995. MPCA has since assumed all
responsibility for the Kummer Landfill under the Act. Therefore, no
further response actions
[[Page 8014]]
under CERCLA are appropriate at this time. Consequently, U.S EPA
proposed to delete the site from the NPL.
EPA, with concurrence from the State of Minnesota, has determined
that all appropriate Fund-financed responses under CERCLA at the Kummer
Sanitary Landfill Superfund Site have been completed, and no further
CERCLA response is appropriate in order to provide protection of human
health and the environment. Therefore, EPA proposes to delete the site
from the NPL.
Dated: February 20, 1996.
