National Oil and Hazardous Substances Pollution Contingency Plan; 
National Priorities List: Deletion of the Red Panther Chemical Company 
Superfund Site

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule; notice of intent.

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

SUMMARY: The Environmental Protection Agency (EPA) Region 4 is issuing 
a Notice of Intent to Delete the Red Panther Chemical Company Superfund 
Site (Site) located in Clarksdale, Mississippi, from the National 
Priorities List (NPL) and requests public comments on this proposed 
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). The EPA and the 
State of Mississippi, through the Mississippi Department of 
Environmental Quality (MDEQ), have determined that all appropriate 
response actions under CERCLA have been completed. However, this 
deletion does not preclude future actions under Superfund.

I. Introduction

    The EPA Region 4 announces its intent to delete the Red Panther 
Chemical Company Superfund Site from the National Priorities List (NPL) 
and requests public comment 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 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). As described in 40 CFR 
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.
    The EPA will accept comments on the proposal to delete this site 
for thirty (30) days after publication of this document in the Federal 
Register.
    Section II of this preamble explains the criteria for deleting 
sites from the NPL. Section III of this preamble discusses procedures 
that the EPA is using for this action. Section IV of this preamble 
discusses where to access and review information that demonstrates how 
the deletion criteria have been met at the Red Panther Chemical Company 
Superfund Site.

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.

III. Deletion Procedures

    The following procedures apply to deletion of the Site:
    (1) The EPA consulted with the State before developing this Notice 
of Intent to Delete;
    (2) The EPA has provided the state 30 working days for review of 
this action prior to publication of it today;
    (3) In accordance with the criteria discussed above, the EPA has 
determined that no further response is appropriate;
    (4) The State of Mississippi, through the Mississippi Department of 
Environmental Quality, has concurred with deletion of the Site from the 
NPL;
    (5) Concurrently with the publication of this Notice of Intent to 
Delete in the Federal Register, a notice is being published in a major 
local newspaper, The Clarksdale Press Register Newspaper. The newspaper 
notice announces the 30-day public comment period concerning the Notice 
of Intent to Delete the Site from the NPL; and
    (6) The 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.
    If comments are received within the 30-day public comment period on 
this document, the EPA will evaluate and respond appropriately to the 
comments before making a final decision to delete. If necessary, the 
EPA will prepare a Responsiveness Summary to address any significant 
public comments received. After the public comment period, if the EPA 
determines it is still appropriate to delete the Site, the Regional 
Administrator will publish a final Notice of Deletion in the Federal 
Register. Public notices, public submissions and copies of the 
Responsiveness Summary, if prepared, will be made available to 
interested parties and in the site information repositories listed 
above.
    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 the 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 Intended Site Deletion

    The following information provides EPA's rationale for deleting the 
Site from the NPL:

Site Background and History

    The Red Panther Chemical Company Site (CERCLIS ID: MSD000272385) is 
located in a mixed commercial-residential area of Clarksdale, Coahoma 
County, Mississippi. The Site area includes, but is not limited to, the 
6.5-acre former Red Panther Facility (RPF) property, the 18th Street 
Neighborhood located to the west of the RPF, the vacant Industrial 
Parcel (IP) located south of the RPF, and the Storm Water Drainage 
Ditch Outfall located about 2,500 feet southwest of the RPF. The 
geographical coordinates of the RPF property are latitude 
34[deg]11'14.67'' North and longitude 90[deg]33'41.85'' West. A 
pesticide formulation plant was operated at the RPF from 1949 to 1996. 
The plant formulated liquid and powdered herbicides, insecticides, and 
fungicides, including products containing toxaphene, aldrin, arsenic, 
dieldrin, and dichlorodiphenyltrichloroethane (DDT).
    In 1999, the EPA conducted surface and subsurface soil sampling of 
the drainage ditches to the east of the property, the former onsite 
leaching field and septic tank, and the rail spur in front of the 
loading dock along the west side of the property. Samples were analyzed 
for metals and pesticides, and results indicated elevated levels of 
arsenic, organo-chlorine pesticides and their degradation by-products.
    In September 2001, the EPA entered into an Administrative 
Settlement Agreement and Order on Consent (ASAOC) with the Site 
Potentially Responsible Party (PRP) group for a PRP-conducted removal 
action and additional characterization. The 2001 ASAOC identified the 
following constituents of concern (COCs) and set performance standards 
governing the removal action for surface and subsurface soils:
     Surface Soil: Arsenic, toxaphene, dieldrin, and total 
chlorinated pesticides. Performance standards were established for 
surface soil COCs at 39 ppm, 3 ppm, 23 ppm, and 100 ppm, respectively; 
and
     Sub-surface Soil: Arsenic, toxaphene, and dieldrin. 
Performance standards were established for sub-surface soil COCs at 220 
ppm, 15 ppm, and 270 ppm, respectively.
    Performance standards are not equivalent to remedial goals. 
Performance standards are developed as site-specific screening levels 
in accordance with the EPA's 1996 Soil Screening Guidance (SSG) and 
2002 Supplemental Guidance for Developing Soil Screening Levels for 
Superfund Sites. SSG is a tool developed by the

[[Page 42815]]

EPA to help standardize and accelerate the evaluation and cleanup of 
contaminated soils at sites on the NPL where future residential land 
use is anticipated. Generally, at sites where contaminant 
concentrations fall below screening levels, no further action or study 
is warranted under CERCLA.
    In late 2002 and early 2003, surface soils, above the 2001 ASAOC 
performance standards, were excavated from the drainage ditches along 
the east side of the Site between the site property boundaries and 
Route 49 (Desoto Avenue). Approximately 825 tons of non-hazardous soils 
were disposed of off-site at the Waste Management Subtitle D landfill 
in Tunica Mississippi. Approximately 75 tons of hazardous soils were 
stockpiled onsite and secured. During the ditch remediation, additional 
soil characterization samples were collected from the Site. Samples 
collected from the northern portion of the Site had elevated levels of 
arsenic only and were not impacted by chlorinated pesticides. Samples 
collected along the railroad on the western portion of the Site had 
elevated levels of arsenic and chlorinated pesticides. Samples 
collected from the southern portion of the Site had lower levels of 
arsenic, but elevated levels of chlorinated pesticides.
    An additional PRP-led removal action was conducted at the Site in 
2005 to remove remaining impacted soils above the 2001 ASAOC 
performance standards. During the additional excavation work, 
approximately 14,500 tons of soils and 1,150 tons of concrete were 
excavated and disposed of off-site at the Waste Management Subtitle D 
landfill in Tunica Mississippi in accordance with the CERCLA Off-Site 
Rule. Approximately 7,500 tons of hazardous soil and 32 tons of 
hazardous concrete were excavated and treated off-site. The hazardous 
soil was split with roughly 5,500 tons being sent to the Emelle, 
Alabama facility for stabilization and the remaining tonnage of 
hazardous soils sent to the Onyx facility in Port Arthur, Texas for 
incineration. Additionally, 233,000 pounds of tank sludges from eight 
aboveground storage tanks (ASTs) were also removed and disposed off-
site at the Emelle, Alabama facility. Post-excavation sampling 
confirmed that the 2001 ASAOC performance standards were met. Site 
excavations conducted in 2001, 2002, and 2005 and sampling of the 18th 
Street Neighborhood were summarized in the Phase II Soil Removal 
Report, dated October 2005. It was prepared by site PRP's and approved 
by the EPA in January 2006.
    During the 2005 removal action, the EPA collected 31 composite 
samples from 30 residential yards in the 18th Street Neighborhood and 
four groundwater samples from active municipal water supply wells. Two 
of the municipal wells sampled were approximately 600 feet deep, and 
the other two municipal wells were approximately 1,000 feet deep. All 
samples were analyzed for pesticides, aluminum, arsenic, and iron. Of 
the 30 residences sampled, 26 samples were above background 
concentrations for pesticides, with dieldrin exceeding the performance 
standard in 11 samples and toxaphene exceeding the performance standard 
in four samples. Sample detections were located near the foundations of 
the residences and the exceedances were determined to be the result of 
the application of dieldrin-based termiticide, therefore further 
removal was not conducted at the residences as the elevated results 
were not considered site related. No pesticides were detected in the 
groundwater samples and metals were not detected at elevated 
concentrations in any samples. Residential sampling conducted in the 
18th St. Neighborhood and groundwater samples collected from municipal 
water supply wells were summarized in a Removal Assessment Letter 
Report, dated December 2005.
    In 2007, groundwater samples were collected from nine temporary 
monitoring wells, one onsite permanent monitoring well, and four 
municipal water supply wells as part of a Site Inspection. The 
temporary well samples were collected from between 25 and 45 feet from 
the top of the casing elevation, depending on depth to water. The 
permanent monitoring well depth was approximately 48 feet. Eight of the 
temporary monitoring wells were installed around the perimeter of the 
Site, with the ninth well being installed in the center of the Site. 
All well samples were analyzed for volatile organic compounds, semi-
volatile organic compounds, metals (including mercury), cyanide, and 
pesticides; the municipal well samples were also analyzed for 
polychlorinated biphenyls. The groundwater at the Site had one 
detection of DDT at a concentration greater than the background well at 
temporary well TW-07. It should be noted that the groundwater sample 
collected from TW-07 was collected from perched water exhibiting highly 
elevated turbidity, and it is believed that the detection was 
associated with the particulate matter.
    In 2010, the EPA conducted a Removal Site Evaluation (RSE) and an 
air deposition study. A total of 76 locations were sampled in all 
directions, up to a quarter mile from the Site, including the 18th 
Street Neighborhood. Composite soil samples were collected from 0 to 3-
inches below ground surface (BGS). Pesticides were detected in all the 
composite samples collected. A total of 32 of the 84 samples (73 
composites, 3 background composites, and 8 duplicates) exceeded three 
times the background concentrations. Sample results from all but one of 
the locations reflected concentrations below 10-5 excess 
cancer risk levels applicable to the detected COCs. There were four 
residential properties with dieldrin soil levels detected above the 
background level of 52 micrograms per kilogram ([micro]g/kg), but below 
the level of 340 ug/kg which corresponds to 10-5 cancer risk 
for a residential scenario. The four residential property soil 
detections likely resulted from application of dieldrin-based 
termiticide as was determined during the 2005 removal action sampling. 
The air deposition study addressed the potential migration pathway from 
wind borne dust resulting from normal operations and/or dust from the 
November 1985 fire at a warehouse at the RPF. At the time, the RPF was 
no longer a production facility but was a warehousing operation. 
Statistical analysis comparing pesticide concentrations collected 
during the EPA's 2010 air deposition study to spatial distance from the 
RPF showed that concentrations seen in the 18th Street Neighborhood are 
unlikely to be the result of such air deposition.
    A Hazardous Ranking System documentation package was prepared for 
the Site. The HRS process evaluates the migration and exposure pathways 
of contaminated site media and gives a numerical score based on the 
cumulative threat for exposure. For the RPF site, groundwater migration 
and soil exposure pathways were evaluated. The HRS process yielded a 
score of 39.43, with 28.5 being the threshold criteria to list a site 
on the NPL. The Site was proposed to the NPL on 3/10/2011 (76 FR 13113) 
and placed as final on the NPL on 9/16/2011 (76 FR 57662). The Site 
CERCLIS ID is MSD000272385.

Remedial Investigation

    On September 26, 2016, the EPA entered into another ASAOC with the 
Red Panther PRPs to perform a Focused Remedial Investigation/
Feasibility Study (FRI/FS). The primary purpose of this ASAOC was to 
determine the nature and extent of contamination and identify any 
threat to the public health, welfare, or environment caused by the 
release or threatened release of hazardous substances, pollutants or

[[Page 42816]]

contaminants at or from the Site by performing a FRI.
    The FRI assessed potential risks posed to residents from dermal 
contact or accidental ingestion of soils in residential areas or off-
site drainage areas; to industrial or commercial workers from dermal 
contact or accidental ingestion of soils at the RPF or IP; to 
accidental ingestion of groundwater from the Mississippi aquifer; and 
to ecological receptors.
    The 2018 FRI included sediment sampling, soil sampling, 
installation of three groundwater monitoring wells, and groundwater 
sampling within four main areas. Those four areas included: The RPF, a 
vacant IP located immediately south-southeast of the RPF, a storm sewer 
drainage ditch located approximately 0.5 miles southwest of the RPF, 
and five residential properties located west of the RPF.
    A significant component of the HRS score, which led to placement of 
the Site on the NPL, was the elevated concentration of pesticides 
detected in a single monitoring well. One of the primary objectives of 
the FRI was to determine the nature and extent of any groundwater 
contamination. The FRI sampling results indicate that soil, sediment, 
and groundwater at the Site do not pose any unacceptable human health 
risks to current and future receptors that exceed the acceptable EPA 
risk range of 10-4 to 10-6 cancer risk. 
Groundwater results were less than three times the background well 
concentration and confirmation results for dieldrin were five times 
lower than the tapwater regional screening level (RSL). Soils evaluated 
at the RPF indicated pesticide concentrations less than the industrial 
risk level established by the site-specific risk assessment. Soil 
samples collected at 18th Street Neighborhood residential properties 
were all below the associated RSLs, except for samples collected near 
the foundations. The exceedances in the foundation samples was 
determined to be related to termiticide usage. Inclusion of aliquots 
from those foundations biased prior results obtained during prior 
sampling events, including the soil exposure pathway used for HRS 
scoring. Additionally, the groundwater sampling conducted during the 
FRI ruled out groundwater contamination as a human health risk, thus 
the EPA selected a no-further-action remedy and is proposing to delete 
the Site from the NPL.
    In addition, the May 2020 Review of Removal Action Confirmatory 
Data Memorandum (Memorandum) from the Site Human Health Risk Assessor 
(HHRA) evaluated the data from four IP samples that would be considered 
surface soil for purposes of residential human exposure (no deeper than 
1 foot). The data from these samples were analyzed for arsenic, 
dieldrin, and toxaphene. The HHRA compared the confirmatory sample data 
to health risk-based levels for a chronic, daily residential receptor 
scenario and found none of the samples had reported levels of these 
analytes that would pose a summed excess cancer risk exceeding 
10-4, or a noncancer hazard quotient (HQ) exceeding 1. The 
Memorandum further stated that the same conclusion is reached even if 
the maximum level for each contaminant from the four sample locations 
is assumed for chronic residential exposure. Based upon these reported 
surface soil data, the Site is protective of human health and the 
environment and does not require use restrictions.
    Cancer risk estimates from the HHRA indicate no unacceptable cancer 
risk is present at the IP from the potentially complete exposure 
pathways to the potential receptor populations. Similarly, hazard index 
estimates also indicate no unacceptable non-cancer hazards from the 
potentially complete exposure pathways to the potential receptor 
populations.
    Removal actions conducted in 2002 and 2005 on the RPF parcels and 
storm water drainage ditch met established performance standards and 
left no hazardous substances, pollutants, or contaminants remaining on 
Site above levels that exceed the threshold for unlimited use and 
unrestricted exposure (UU/UE). Residential yards, in the 18th St. 
Neighborhood, sampled during the 2005 removal action and 2010 RSE 
showed no site-related hazardous substances, pollutants, or 
contaminants existed above levels for UU/UE. Subsequent sampling and 
data analysis presented in the 2018 FRI and May 2020 HHRA Memorandum 
support this conclusion.

Selected Remedy

    Based upon FRI sampling results indicating that soil, sediment, and 
groundwater at the Site do not pose any unacceptable human health risks 
to current and future receptors, the EPA issued the ROD on August 21, 
2019 that selected a remedy of No Further Action. The FRI confirmed 
that previous removal actions conducted between 2002 through 2005 
addressed unacceptable risks to human health and the environment. The 
Administrative Record for the Red Panther Chemical Company Site is 
available for review at the Carnegie Public Library, located at 114 
Delta Avenue, Clarksdale, Mississippi, and at the EPA Region 4 Records 
Center in Atlanta, Georgia. The State of Mississippi, as represented by 
the MDEQ, supported the No Further Action remedial alternative for the 
Site as protective of human health and the environment.

Institutional Controls

    Per the ROD, institutional controls (ICs) are not required to 
restrict land or groundwater use throughout the Site. As a result of 
removal actions conducted at the Site between 2002 through 2005, the 
cleanup achieved the UU/UE threshold and does not require ICs for long-
term remedy protectiveness. The RPF currently has an industrial zoning 
designation and is expected to remain industrial in the future. In 
addition to the industrial zoning, maximum surface soil concentrations 
for both dieldrin and toxaphene from the IP assessed in the HHRA showed 
acceptable risks (i.e., not exceeding 10-4 excess cancer 
risk or HQ of 1) for both industrial and residential receptors.

Community Involvement

    The EPA has been actively engaged with the affected community and 
has strived to maintain a collaborative relationship with those 
interested residents during the FRI and the remedy selection process.

Determination That the Criteria for Deletion Have Been Met

    The EPA has followed all procedures required by 40 CFR 300.425(e), 
Deletion from the NPL. The EPA consulted with the State of Mississippi 
prior to developing this Notice. The EPA determined that both the EPA 
and MDEQ have conducted all appropriate response actions required and 
that no further response action for the Site is appropriate. The EPA is 
publishing a notice in a major local newspaper, The Clarksdale Press 
Register Newspaper, to inform the public of its intent to delete the 
Site and how to submit comments. The EPA placed copies of documents 
supporting the proposed deletion in the site information repository; 
these documents are available for public inspection and copying.
    The selected remedial action objectives and associated cleanup 
levels for the surface and subsurface soils are consistent with agency 
policy and guidance. Based on information currently available to the 
EPA, no further Superfund response at the Site is needed to protect 
human health and the environment.
