National Oil and Hazardous Substance Pollution Contingency Plan; 
National Priorities List: Deletion of the Kerr-McGee Sewage Treatment 
Plant Superfund Site

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

-----------------------------------------------------------------------

SUMMARY: The U.S. Environmental Protection Agency (EPA) Region 5 is 
publishing a direct final Notice of Deletion of the Kerr-McGee Sewage 
Treatment Plant Superfund Site (Site) located in West Chicago, 
Illinois, 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 Illinois, through the 
Illinois Environmental Protection Agency (IEPA), because EPA has 
determined

[[Page 11590]]

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 April 22, 2013 unless 
EPA receives adverse comments by March 21, 2013. 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.

I. Introduction

    EPA Region 5 is publishing this direct final Notice of Deletion of 
the Kerr-McGee Sewage Treatment Plant Superfund Site (Kerr-McGee STP 
Site) from the National Priorities List (NPL). 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). 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 April 22, 2013 unless EPA 
receives adverse comments by March 21, 2013. 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 Kerr-McGee STP 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;

[[Page 11591]]

    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 conducts 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 Site:
    (1) EPA consulted with the State of Illinois 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 IEPA, 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, ``The 
Daily Herald.'' 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 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 
Site from the NPL.

Site Background and History

    The Kerr-McGee STP Site is located in West Chicago, DuPage County, 
Illinois, and is comprised of the West Chicago Sewage Treatment Plant 
and approximately 1.2 miles of the West Branch DuPage River. The Site 
property and the sediments, banks and floodplain soils along the river 
were contaminated with radioactive thorium waste materials that 
originated at a thorium milling facility in West Chicago known as the 
Rare Earths Facility (REF). West Chicago is located approximately 30 
miles west of downtown Chicago, has a population of approximately 
27,086 (2010 census), and is characterized as suburban, with primarily 
high-density, single-family residential housing. The STP property is 
owned and operated by the City of West Chicago and is located at 
Illinois Routes 59 and 38 at Sarana Drive. The West Branch DuPage River 
is located along the eastern edge of the STP property and flows south 
through forest preserve and residential properties. The STP site 
extends as far south as the river's confluence with Kress Creek; all 
areas of the river south of that point are included as part of the 
Kerr-McGee Kress Creek/West Branch DuPage River Site, a related site in 
the West Chicago area.
    The REF, operated by Lindsay Light and Chemical Company and its 
successors from 1932 until 1973, produced radioactive elements such as 
thorium, radium and uranium, along with gas lantern mantles, by 
extracting the elements from monazite sands and other ores. These 
operations resulted in the generation of radioactive mill tailings. 
Radioactive ore, tailings and process wastes from the REF were used at 
the STP property as fill material and to contour grounds, and also were 
used as fill along portions of the riverbank. Over time, some of the 
contaminated materials located on the STP property and along the 
riverbank entered the river through erosion and surface water runoff 
and were deposited downstream in sediments, banks and flood plain 
soils. Kerr-McGee purchased the REF in 1967 and maintained operations 
until closing the facility in 1973.
    EPA proposed the STP site to the National Priorities List (NPL) on 
October 15, 1984 (49 FR 40320), and added it to the final list on 
August 30, 1990 (55 FR 35502). In 1985, Kerr-McGee entered into an 
agreement with the City of West Chicago under which Kerr-McGee 
conducted cleanup activities at the STP property, removing an estimated 
57,000 cubic yards of material from the site during 1986 and 1987.
    Contaminated materials were left behind in certain areas of the STP 
property and along the riverbank, and the 1.2 mile stretch of the river 
was not addressed by the City's agreement with Kerr-McGee. No other 
removal actions were taken at the site until the EPA required the time-
critical removal action discussed below. Currently, there are no 
redevelopment plans for the STP site.

Remedial Investigation and Feasibility Study

    EPA began a fund-lead remedial investigation/feasibility study (RI/
FS) at the STP site in 1992. EPA's RI was designed to (1) identify 
areas of the STP property where residual contamination was left behind 
during the mid-1980s cleanup, and (2) fully investigate the nature and 
extent of contamination in the river. During settlement negotiations 
with Kerr-McGee, a potentially responsible party (PRP), associated with 
this site and three other related NPL sites in the West Chicago area, 
Kerr-McGee agreed to take over the completion of the RI/FS and to 
conduct a time-critical removal action at the STP property. EPA then 
divided the STP site into two operable units: An Upland Operable Unit 
(STP Upland OU) consisting of the STP property, and a second OU, 
consisting of the riverbank along the STP property and the 1.2 mile 
stretch of the West Branch DuPage River from the STP property to the 
confluence with Kress Creek (STP River OU).
    On October 7, 2003, EPA signed an action memorandum for a time-
critical removal action at the STP Upland OU, and on October 16, 2003, 
EPA entered into an administrative order on consent (AOC) in which 
Kerr-McGee agreed to conduct the removal action. The selected removal 
action included excavation and offsite disposal of

[[Page 11592]]

materials contaminated with radiation until predetermined verification 
points based upon relevant and appropriate state and federal 
regulations were achieved. The predetermined verification points, 
consisting of specified depths/elevations at numerous points across the 
STP property, were based on extensive site characterization data and 
were designed to remove materials that had been identified during site 
characterization activities as exceeding 7.2 picoCuries per gram (pCi/
g) combined radium. (The relevant and appropriate state and federal 
regulations include a health-based surface soil standard of 5 pCi/g 
above background, and background in the West Chicago area was 
determined to be 2.2 pCi/g.) The selected removal action also included 
backfilling and restoring the excavated areas of the site. Kerr-McGee 
began on-site removal action work at the STP Upland OU in October 2003.
    On November 21, 2003, EPA signed an AOC with Kerr-McGee under which 
they agreed to complete the RI/FS at the STP site. Kerr-McGee completed 
the RI and FS reports, and EPA completed the human health and 
ecological risk assessment reports. Human health risks that were 
identified above protective levels include soil ingestion and 
inhalation (non-Radon) risks to maintenance workers and radon 
inhalation risks to future residential users at the Upland OU. At the 
STP River OU, residential risks to radon inhalation and recreational 
risks to fish ingestion were found to be above a protective level. For 
the ecological risk assessment, chemical and radiation effects were 
assessed at both OUs. EPA determined that potential risks to 
environmental receptors would be minimized or eliminated by the cleanup 
actions taken at the site.
    Kerr-McGee completed most of the on-site removal action work at the 
STP Upland OU during 2004. A total of 6,557 loose cubic yards of 
contaminated soil was removed from the site. Because portions of the 
STP property were used to support remedial action work at the STP River 
OU, final restoration activities could not be completed at the Upland 
OU until 2006. EPA and the State conducted a pre-final inspection of 
the removal action work at the STP Upland OU on August 8, 2006 and 
determined that Kerr-McGee had constructed the remedy in accordance 
with the removal action plans and specifications. One minor item was 
identified during the pre-final inspection; regrading and reseeding of 
a small area around a storm inlet manhole--and that action was 
completed by August 11, 2006.
    In accordance with the AOC for the STP Upland OU, on September 12, 
2006, Kerr-McGee prepared and submitted a final removal action report 
to EPA for review and approval. EPA approved the removal action report 
and issued a Notice of Completion of activities required by the AOC on 
August 12, 2008. The cost of the time-critical removal action at the 
STP Upland OU reported in the final removal action report was $3.15 
million.

Record of Decision Findings

    On September 30, 2004, EPA signed a Record of Decision (ROD) for 
the STP Site. The ROD for the STP Site addressed both the Upland OU and 
the River OU and identified the following remedial action objectives 
(RAOs) for the site:
     Reduce risks to human health and the environment presented 
by sediments and soils containing elevated levels of total radium by 
reducing soil concentration to levels that are consistent with the 
requirements outlined in 40 CFR part 192 (the regulations implementing 
the Uranium Mill Tailings Radiation Control Act) and Illinois Source 
Material Milling Regulations; and
     Mitigate, to the extent practicable, potential adverse 
effects to the environment as a result of implementation of remedial 
activities at the site.
    For the STP Upland OU, the ROD selected no further action after 
completion of the ongoing time-critical removal action at that portion 
of the site. For the STP River OU, the ROD selected the following 
remedy:
     Excavation and off-site disposal of contaminated soils and 
sediments from the site using mechanical ``dry excavation'' techniques. 
Contaminated materials are those materials within pre-defined 
excavation envelopes based on extensive site characterization 
activities that identified materials exceeding 7.2 pCi/g;
     Mitigation and restoration activities to restore aquatic 
and terrestrial areas of the site, including revegetation of 
appropriate areas and stabilization of stream banks;
     Monitoring and maintenance of restored areas to assess the 
effectiveness of stabilization and revegetation measures.
    Similar to the removal action at the STP Upland OU, the cleanup at 
the STP River OU included excavation of materials contaminated with 
radiation until predetermined verification points were achieved. The 
predetermined verification points, consisting of specified depths/
elevations at numerous points, were based on extensive site 
characterization data and were designed to remove materials that had 
been identified as exceeding 7.2 pCi/g.
    The ROD specified that the selected remedy for the site is 
protective of human health and the environment and will not result in 
hazardous substances, pollutants or contaminants remaining on-site 
above levels that allow for unlimited use and unrestricted exposure. As 
a result, institutional controls are not required for the Site.
    In a 2005 federal consent decree with the United States, EPA, 
Department of Interior, and the State of Illinois, Kerr-McGee agreed to 
perform the remedial design/remedial action (RD/RA) at the STP River OU 
and to complete the removal action at the STP Upland OU in accordance 
with the AOC for that portion of the site. Kerr-McGee conducted the RD 
for the STP River OU as required by the ROD, and the STP River OU was 
divided into two discreet ``Reaches'' for design and construction 
purposes. Reach 5A comprises the northern portion of the STP River OU, 
and extends from the STP property to Gary's Mill Road. Reach 5B 
comprises the southern portion of the STP River OU and extends from 
Gary's Mill Road to the river's confluence with Kress Creek. On-site 
remedial action construction work began in Reach 5A on November 1, 
2004, after EPA conditionally approved the remedial design for a 
portion of that reach. Remedial action work continued in Reaches 5A and 
5B of the site during portions of 2005 and 2006. The sequencing of work 
at the STP River OU depended on Kerr-McGee's progress conducting 
remedial action work at the related Kerr-McGee Kress Creek site. Kerr-
McGee conducted remedial activities at the STP River OU as planned.
    Reach 5A of the site was cleaned up using dry excavation methods. 
Individual excavation areas located along the river bank and/or in the 
river corridor were isolated with ``super sac'' or sandbag enclosures, 
and the area within each enclosure was then dewatered so that 
excavation and restoration work could proceed in relatively dry 
conditions. A total of 1,432 loose cubic yards of contaminated soil and 
sediment was removed from Reach 5A. EPA and the State conducted a pre-
final inspection of the remedial action work in Reach 5A on August 8, 
2006, and determined that Kerr-McGee constructed the remedy for that 
portion of the site in accordance with the RD plans and specifications. 
Minor items were identified during the pre-final inspection, which 
included completing

[[Page 11593]]

several plantings and removing some silt fence, and these were 
completed by August 11, 2006.
    Dry excavation of Reach 5B of the site was accomplished by using a 
pump bypass and dewatering system which (1) Isolated the entire reach 
with sheet pile diversion and backflow dams, (2) diverted the flow of 
the West Branch DuPage River through a 48'' bypass pipe, and (3) used 
dewatering sumps within the Reach to control groundwater in the 
excavation areas. All excavation work associated with the removal of 
contaminated materials was completed by September 9, 2006, and all 
contaminated materials were shipped off-site by September 20, 2006. The 
pump bypass system remained in operation to complete bank stabilization 
activities and in-stream habitat enhancements in dry conditions. Under 
a separate consent decree between Kerr-McGee and the local communities, 
Kerr-McGee was required to conduct additional habitat enhancement 
activities that were not required by the 2005 federal consent decree. 
These additional activities necessitated the pump bypass system 
operating for a longer period of time than would have been required to 
achieve the requirements of the ROD and the 2005 federal consent 
decree.
    EPA and the State conducted a pre-final inspection of the remedial 
action work in Reach 5B on September 29, 2006, and determined that 
Kerr-McGee constructed the remedy for that portion of the site in 
accordance with the RD plans and specifications.

Cleanup Goals

    Contaminated areas at the Kerr-McGee STP site were identified by 
the installation of hundreds of soil and sediment borings where gamma 
radiation logging was conducted to determine the lateral and vertical 
extent of contamination. To verify that the cleanup goals were achieved 
at the STP Upland OU, confirmatory soil samples were collected and the 
results were documented in the Final Removal Action Report, dated 
September 12, 2006. Compliance with the 7.2 pCi/g cleanup standard in 
the STP River OU was determined using field surveys to verify that 
excavation in the river and flood plain had achieved the identified 
elevations and lateral extent where contamination was deposited.
    In accordance with the 2005 federal consent decree, the extensive 
excavation and radiation logging, and the field surveys document the 
successful completion of the remedial action and show that verification 
soil samples are not necessary. In addition, the 7.2 pCi/g cleanup 
standard at the River OU is a residential cleanup number which 
represents a conservative standard for the reasonably anticipated uses 
of the River area.

Operation and Maintenance

    There are no remaining operation and maintenance requirements for 
the Kerr-McGee STP Site. All response activities are complete and all 
physical components of the response have been removed.

Five-Year Review

    Hazardous substances will not remain at the site above levels that 
allow unlimited use and unrestricted exposure after the completion of 
the remedial action. Pursuant to CERCLA section 121(c), and as provided 
in the current guidance on Five Year Reviews: OSWER Directive 9355.7-
03B-P, Comprehensive Five-Year Review Guidance, June 2001, five-year 
reviews are not required for this site.

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 Illinois, 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 Illinois through the 
Illinois Environmental Protection Agency, 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 April 22, 2013 unless EPA receives adverse comments by 
March 21, 2013. If adverse comments are received within the 30-day 
public 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.
