40 CFR Part 300

[EPA-HQ-SFUND-1992-0007; FRL-9997-23-Region 7]

National Oil and Hazardous Substances Pollution Contingency Plan;
National Priorities List: Partial Deletion of the Cleburn Street Well
Superfund Site

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) Region 7 is
publishing a direct final Notice of Partial Deletion of the Cleburn
Street Well Superfund Site (Site), located in Grand Island, Nebraska,
from the National Priorities List (NPL) for of the Operable Unit (OU) 1
and OU4. This partial deletion pertains to OU1--Contaminated sub-
surface soil at former One-Hour Martinizing (OHM) and OU4--Soil and
Groundwater at Ideal Cleaners. The remaining OU2, OU3, and OU5 will
remain on the NPL and are not being considered for deletion as part of
this action. The NPL, promulgated pursuant to section 105 of the
Comprehensive Environmental Response, Compensation, and Liability Act
(CERCLA) of 1980, as amended, is an appendix of the National Oil and
Hazardous Substances Pollution Contingency Plan (NCP). This direct
final partial deletion is being published by EPA with the concurrence
of the State of Nebraska, through the Nebraska Department of
Environmental Quality (NDEQ); because EPA has determined that all
appropriate response actions at these identified parcels under CERCLA
have been completed. However, this partial deletion does not preclude
future actions under Superfund, including Five Year Reviews.

DATES: This direct final partial deletion is effective September 27,
2019 unless EPA receives adverse comments by August 28, 2019. If
adverse comments are received, the EPA will publish a timely withdrawal
of the direct final partial deletion in the Federal Register informing
the public that the partial deletion will not take effect.

I. Introduction

    EPA Region 7 is publishing this direct final Notice of Partial
Deletion for the Cleburn Street Well Superfund Site, (Site), from the
National Priorities List (NPL). This partial deletion pertains to the
soil and subsurface soil at the One-Hour Martinizing facility (OHM)
(OU1) and the soil and groundwater at Ideal Cleaners (OU4). The NPL
constitutes appendix B of 40 CFR part 300 which is the National Oil and
Hazardous Substances Pollution Contingency Plan (NCP), which the EPA
promulgated pursuant to section 105 of the Comprehensive Environmental
Response, Compensation and Liability Act (CERCLA) of 1980, as amended.
The 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 partial deletion of the
Cleburn Street Well Superfund Site is proposed in accordance with 40
CFR 300.425(e) and is consistent with the Notice of Policy Change:
Partial Deletion of Sites Listed on the National Priorities List. 60 FR
55466 (November 1, 1995). As described in 40 CFR 300.425(e)(3) of the
NCP, a portion of a site deleted from the NPL remains eligible for
Fund-financed remedial action if future conditions warrant such
actions.
    Section II of this document explains the criteria for deleting
sites from the NPL. Section III discusses procedures that the EPA is
using for this action. Section IV discusses OU1 and OU4 of the Cleburn
Street Well Superfund Site and demonstrates how it meets the deletion
criteria. Section V discusses EPA's action to partially delete the Site
media and/or parcels from the NPL unless adverse comments are received
during the public comment period.

II. NPL Deletion Criteria

    The NCP establishes the criteria that the 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), the 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, the 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. The EPA conducts such five-year reviews even if a site is
deleted from the NPL. The 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. Partial Deletion Procedures

    The following procedures apply to the deletion of OU1 and OU4 of
the Site:
    (1) The EPA has consulted with the State of Nebraska prior to
developing this direct final Notice of Partial Deletion and the Notice
of Intent for Partial Deletion published in the ``Proposed Rules''
section of this issue of the Federal Register.
    (2) The EPA has provided the State 30 working days for review of
this document and the parallel Notice of Intent for Partial Deletion
prior to their publication in this issue of the Federal Register, and
the State, through the NDEQ, has concurred on the partial deletion of
the Site from the NPL.
    (3) Concurrently with the publication of this direct final Notice
of Partial Deletion, a notice of the availability of the parallel
Notice of Intent for Partial Deletion is being published in a major
local newspaper, The Grand Island Independent. The newspaper notice
announces the 30-day public comment period concerning the Notice of
Intent for Partial Deletion of the Site from the NPL.
    (4) The EPA placed copies of documents supporting the partial
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 partial deletion action, the EPA will publish a
timely notice of withdrawal of this direct final Notice of Partial
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 for Partial Deletion and the comments already
received.
    Deletion of a portion of a site from the NPL does not itself
create, alter, or revoke any individual's rights or obligations.
Deletion of a portion 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 further
response actions, should future conditions warrant such actions.

IV. Basis for Partial Site Deletion

    The following information provides the EPA's rationale for deleting
OU1 and OU4 of the Cleburn Street Well Superfund Site from the NPL:

Site Background, Location, and History

    The Cleburn Street Well Superfund Site (CERCLIS ID #NED981499312)
is located within the urban setting of Grand Island, Nebraska. Grand
Island's 2016 census reports a population of 51,517. The Site is
situated in central Nebraska, approximately two miles north of the Wood
River and approximately seven miles northeast of the Platte River. The
Site encompasses a portion of the downtown area and is surrounded by a
variety of light industries, commercial businesses and residential
dwellings. Surface runoff is controlled by man-made features typically
present in a city (storm sewers/gutters) and is eventually discharged
into the Wood River.
    The Cleburn Street Well Site consists of four distinct volatile
organic compound (VOC) release areas located within the central portion
of the City of Grand Island, Nebraska. Three of the source areas are
locations of commercial dry-cleaning businesses: Former One-Hour
Martinizing (OHM) (OUs 1 and 2), Ideal Cleaners (OU3), and former
Liberty Cleaners (OU4). Ideal Cleaners is currently an operating
business. The fourth release area is the location of the former
Nebraska Solvent Distribution Company (OU5).
    OU1 (former OHM) is located on a property which includes a
structure with concrete slab on grade construction. The former OHM dry
cleaner building is currently being used temporarily as commercial
building space for a construction business. A used tire shop operates
in an adjacent building. The immediate vicinity of the former OHM
predominantly consists of commercial businesses; however, residential
properties are also present.
    OU4 (Liberty Cleaners) is an operating business located in a
predominantly residential area.
    Contamination at the Cleburn Street Well Site was first discovered
in March 1986 when the Nebraska Department of Health detected
tetrachloroethene (PCE) at the Cleburn Street public drinking water
supply well. The EPA became involved in 1987 and conducted a
preliminary assessment with subsequent site investigations resulting in
the identification of four separate source areas: Three dry cleaning
facilities--OHM, Liberty Cleaners, and Ideal Cleaners; and a former
solvent distribution company (Nebraska Solvent Company). These source
areas are all within an approximate 1,960 feet radius of the Cleburn
Street well, which is located near the intersection of Cleburn Street
and North Front Street.
    The EPA follow-on investigations identified significant PCE and
trichloroethene (TCE) contamination OU1 and OU4 locations. The release
of hazardous substances resulted in the contamination above maximum
contaminant levels (MCLs), of the aquifer providing potable water to
the city of Grand Island. The MCL of both TCE and PCE is 5 parts per
billion, as defined by the 1976 Safe Water Drinking Act. This
necessitated the abandonment of the Cleburn Street public water supply
well and subsequently the abandonment of both the Lincoln and Pine
Street public supply wells, also located in the area.
    The State of Nebraska has designated the aquifer impacted by the
Cleburn Site as a Class GA Groundwater Supply. Class GA Groundwater is
a groundwater supply which is currently being used as a public drinking
water supply or is proposed to be used as a public drinking water
supply. The contamination detected caused the State of Nebraska to
designate the Site as a Remedial Action Class 1, requiring the ``most
extensive remedial action measures'' to clean up and restore the
groundwater to drinking water quality suitable for all beneficial uses.

Remedial Investigation and Human Health Assessments

    The Site was proposed for the National Priorities List, or NPL, on
July 29, 1991 (56 FR 21460) and listed as final on the NPL on October
14, 1992 (57 FR 47180). The remedial investigation was completed in May
1993 and the Feasibility Study was completed in July 1995.
    The human health risk assessment completed in 1993 evaluated risk
at OU1 and OU4. Current groundwater exposures are not likely because
city residents have access to city water and are not known to be using
private wells; and soil contamination is below ground and not
accessible for direct contact exposures. Although residents are not
believed to be currently exposed to contamination, the risk assessment
evaluated several potential future exposure pathways. Future residents
could be exposed to contaminated groundwater via ingestion, inhalation,
and direct contact if private wells are installed and used in place of
city water; and future development could also result in direct contact,
ingestion, and inhalation exposures to contaminated soils.
    The 1993 human health risk assessment determined that the
carcinogenic risk associated with

exposure to soil at the OU1 and OU4 source was low with an estimated
excess cancer risk of 2x10-7.
    A screening level ecological risk assessment was performed in 1998.
It was determined that there were no ecological exposure pathways.

Remedial Action Objectives

    The EPA composed the 1996 Record of Decision (ROD) to address soil
and groundwater contamination at all three dry cleaner locations.
Remedy selection was based on the following 1996 ROD Remedial Action
Objectives, or RAOs:
    The RAO for groundwater at OU4, defined in the 1996 ROD, is
restoration of the shallow aquifer to its designated use as a drinking
water source.
    The general RAO for groundwater which provides for the protection
of human health includes the prevention or minimization of ingestion of
groundwater having a carcinogenic risk greater than 1x10-6
and/or a HI for noncarcinogens greater than 1. The specific remediation
goals which would achieve this objective are the MCLs for PCE
contamination. The RAO for groundwater which is protective of the
environment involves the restoration of groundwater quality to below
MCLs for all contaminants which have MCLs. The primary contamination of
concern is PCE.
    The following RAO for OU1 and OU4 soils is defined in the 1996 ROD:
    The RAO for soil which is protective of human health includes the
prevention or minimization of direct contact with soils having a
carcinogenic risk greater than 1 x 10-6, and/or an HI for
noncarcinogens greater than 1. The specific remediation goals which
would achieve this objective have not been established. However, the
agency's soil screening levels for PCE will be used as a guideline to
determine the level of protectiveness achieved by the remedial action.
The soil RAO also includes the prevention of migration of PCE
contaminant from soil that would result in groundwater contamination in
excess of the MCL with a site-specific cleanup level of 0.89 mg/kg.

Selected Remedy, Operations, and Results

    Per the 1996 ROD, the following are the selected remedies for OU1
and OU4.
    The selected remedies for OU1 (Soils at OHM) are:

--Institutional controls to restrict groundwater use and prevent
exposures
--Extraction of subsurface contaminants using soil vapor extraction
(SVE)
--Treatment of extracted vapors by carbon absorption

    The selected remedies for OU4 (Ideal Cleaners) are:

--Natural attenuation and groundwater monitoring for ten years
--Institutional controls to restrict groundwater use and prevent
exposures
--Contingency action of in situ treatment of source soil by SVE*

    * The SVE system was not warranted or needed to achieve the clean-
up goal at OU4, and the SVE contingency remedy ws not imlemented.
OU1
    The remedial design for OU1 actions selected in the 1996 ROD were
completed in September 1997, and the remedies were constructed and
operating by October 1998. Following the first year of operation, on
October 29, 1999, a joint inspection was conducted by the EPA and the
NDEQ, and the remedies were determined to be operational and
functional.
    The OU1 SVE system was operated by NDEQ for a period of
approximately four years between 1998 and 2002, and for an additional
year from April 2005 through early 2006. In April 2006, NDEQ notified
the EPA of its position that the OU1 remedy was complete because soil
vapor concentrations had reached asymptotic levels and no further mass
removal was being achieved by the SVE system. As a part of the 2007
Source Investigation for OU2, Groundwater at former One-Hour
Martinizing, soil samples were collected from seven locations from
within the footprint of the building in the vadose zone, less than 24
feet below ground surface. All soil samples exhibited PCE
concentrations less than the site-specific cleanup level of 0.89 mg/kg.
In a letter dated February 22, 2007, the EPA agreed with NDEQ that the
OU1 remedy had achieved its intended purpose of addressing source
soils. The 2012 ROD Amendment, which selected in-situ thermal remedial
action for OU2, also summarized the soil clean-up at OU1, ``The
remediation goals for COC's detected in the shallow subsurface soils
have been achieved by operation of the SVE system at the facility.''
OU4
    The Remedial Design for OU4 was completed in June 1997. The
remedial action for the natural attenuation remedy with monitoring
included the installation of two downgradient monitoring wells and six
quarterly monitoring events. The final RA Report for OU4 was approved
on July 14, 1999. The remedy for OU4 was turned over to the State for
O&M on September 10, 1999. Since 1999, NDEQ has sampled the monitoring
wells at regular intervals. Nine of the last 11 groundwater sampling
events for all OU4 wells have been non-detect and all groundwater
monitoring wells have been under the MCL since the year 2001. After
2012, NDEQ management, with EPA concurrence, made the decision not to
sample OU4 wells henceforth as there is no evidence of residual
contamination.

Institutional Controls

    Institutional controls at the Cleburn Well Superfund Site were
implemented in February 1988 when the city of Grand Island passed
Ordinance No. 8363, which restricts the use of groundwater pumped from
within the Site and requires registration of new wells and adherence to
permitting requirements within the Site.

Five-Year Review

    Statutory five-year reviews are required at the Cleburn Street Well
Superfund Site since hazardous substances remain at the Site above
levels that allow for unlimited use and unrestricted exposure. Five-
year reviews were completed for the Site in 2003, 2008, 2013, and 2018.
For both OU1 and OU4, the remedy is protective of human health and the
environment. There are no issues or recommendations for either OU1 or
OU4. The next five-year review is scheduled for 2023.

Community Involvement

    Throughout the process from development of the remedy to completion
of the remedial activities, all phases of the Site remediation have
been an extensive community involvement process with input from Federal
and State regulators, the City of Grand Island, and members of the
public. Over the life of the project, there were public comment periods
and public meetings to ensure that the local residents were able to
contribute to the process and express their opinions.
    Public involvement has been included throughout the remediation
process at this Site and has been memorialized in site documents
including the Record of Decision, Proposed Plans, and EPA Five-Year
Reviews. Public comments are also solicited during this partial
deletion with a notice in the local newspaper, the Grand Island
Independent.

Determination That the Criteria for Deletion Have Been Met

    In accordance with 40 CFR 300.425(e), EPA Region 7 detemined the
response at OU1 and OU4 of the Site

(the subject of this deletion) meet the substantive criteria for
deletion from the NPL. The EPA has consulted with and has the
concurrence of the State of Nebraska. All responsible parties or other
persons have implemented all appropriate response actions required. All
appropriate Fund-financed response under CERCLA was implemented, and no
further response action by responsible parties is appropriate.
    The implemented remedies at OU1 and OU4 have achieved the degree of
cleanup specified in the remedy decisions for all pathways of exposure.
All selected remedial action objectives and associated cleanup levels
are consistent with agency policy and guidance. No further Superfund
response is needed to protect human health and the environment.

V. Partial Deletion Action

    The EPA, with concurrence of the State of Nebraksa through the
NDEQ, has determined that all appropriate response actions under
CERCLA, have been completed. Therefore, the EPA is deleting OU1 and OU4
from the Cleburn Street Well Superfund Site from the NPL.
    Because the EPA considers this action to be noncontroversial and
routine, the EPA is taking it without prior publication. This action
will be effective September 27, 2019 unless EPA receives adverse
comments by August 28, 2019. If adverse comments are received within
the 30-day public comment period, the EPA will publish a timely
withdrawal of this direct final Notice of Partial Deletion before the
effective date of the partial deletion and it will not take effect. The
EPA will prepare a response to comments and continue with the deletion
process on the basis of the notice of intent to partially delete and
the comments already received. There will be no additional opportunity
to comment.
