I. Introduction

    EPA Region 4 announces its intent to delete the Fairfax St. Wood 
Treaters 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 document explains the criteria for deleting 
sites from the NPL. Section III of this document discusses procedures 
that the EPA is using for this action. Section IV of this document 
discusses where to access and review the information that demonstrates 
how the deletion criteria have been met at the Fairfax St. Wood 
Treaters Superfund Site and demonstrates how it meets the deletion 
criteria.

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

[[Page 36370]]

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. 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 document 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 Florida, through the Florida Department of 
Environmental Protection, 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 Florida Times-Union. The newspaper notice 
announces the 30-day public comment period concerning the Notice of 
Intent to Delete the site from the NPL.
    (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 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 Fairfax St. Wood Treaters (FSWT) (CERCLIS ID: FLD000623041) 
Superfund site encompasses 12.5 acres and is located at 2610 Fairfax 
Street, in a predominantly residential area of Jacksonville, Duval 
County, Florida. Features of the FSWT facility included a burned 
building, parking lot, drip pad, former tank farm, and retention pond. 
FSWT is bordered to the north by St. Johns/CSX railroad tracks, to the 
east by Fairfax Street and residential properties beyond, to the south 
by West 14th Street and residential properties beyond, and to the west 
by Susie E. Tolbert and R.V. Daniels Elementary Schools (STES) and by 
residential properties on Pullman Court. Moncrief Creek is located 
about 1,000 feet west of the FSWT property. Overflow from the FSWT 
retention pond flows into Moncrief Creek via a city drainage pipe, 
which collects stormwater from the general area.
    From 1980 to 2010, Wood Treaters, LLC operated a wood treating 
facility that pressure-treated utility poles, pilings, heavy timber 
items, and plywood lumber products using the wood treating preservative 
chromated copper arsenate (CCA). CCA is characterized by a bright green 
color and is composed of waterborne oxides, or salts, of chromium, 
copper, and arsenic.
    As a result of the wood treating operations and EPA's understanding 
of the process at the facility, some of the contaminated soil is 
contaminated with Resource Conservation and Recovery Act (RCRA) Listed 
Hazardous Waste (F035). Under 40 CFR 261.31, F035 Listed hazardous 
waste is defined as ``Wastewater (except those that have not come into 
contact with process contaminants), process residuals, preservative 
drippage, and spent formulations from wood preserving processes 
generated at plants that use inorganic preservatives containing arsenic 
or chromium.'' Under EPA's ``contained-in'' policy, contaminated media 
(e.g., groundwater, soil, or sediments) is considered to contain RCRA 
hazardous waste: (1) When media is contaminated with characteristic 
hazardous waste and exhibits a characteristic of hazardous waste; or 
(2) when the media is contaminated with hazardous constituents from 
RCRA Listed Hazardous Waste. (63 FR 28617, May 26, 1998). For F035, the 
RCRA hazardous constituents are arsenic and chromium. If contaminated 
media (e.g. soil) contain Listed Hazardous Waste, then once generated 
(i.e., excavated from the ground) they are with limited exceptions, 
subject to all applicable RCRA hazardous waste requirements until EPA 
(or an authorized State) determine the media no longer contains 
hazardous waste. These RCRA requirements were identified in the ROD as 
``applicable or relevant and appropriate requirements'' (ARARs) 
consistent with CERCLA Section 121(d)(2) and the National Contingency 
Plan (NCP) as well as EPA guidance. In addition, due to the elevated 
concentrations of arsenic and chromium in soil and residual waste in 
the former process area, there is a possibility that this soil/waste 
could be determined by the Toxicity Characteristic Leaching Procedure 
(TCLP) to be RCRA Toxicity characteristic waste under 40 CFR 261.24 
[D004 and D007]. Residual waste material in pipes and drains are 
classified as a RCRA Listed hazardous waste [F035]. Building and other 
man-made debris that is contaminated with this Listed hazardous waste 
may be hazardous debris under RCRA regulations.

[[Page 36371]]

    Between 1980 and 1990, there was no stormwater management system on 
the facility. The topography of the FSWT property and the surrounding 
area is generally flat; therefore, stormwater was either directed to 
the STES retention pond or flowed overland across the FSWT property. 
Uncontrolled stormwater contaminated with CCA from the wood treating 
process is believed to have overflowed onto neighboring properties 
during this time, resulting in CCA contaminated soil. In 1990, FSWT 
installed a stormwater collection and retention system, including site 
grading and paving for drainage, stormwater collection swales, 
diversion berms, and a polyethylene-lined retention pond.
    After 1990, stormwater that collected in the treated wood storage 
yard and areas other than the drip pad was diverted to ditches located 
along the northern, southern, and western property boundaries. These 
ditches drained into the retention pond at the northwestern corner of 
the property. An overflow pipe is located in the retention pond so that 
water overflows into the pipe and discharges into nearby Moncrief 
Creek, a tributary of the Trout River.
    Wood Treaters, LLC filed for bankruptcy in July 2010. In August 
2010, after Wood Treaters, LLC, abandoned the facility, the EPA, at the 
request of the FDEP, conducted emergency response (ER) activities at 
the facility that included pumping out the water contained in the 
secondary containment area and retention pond, removing product in 
tanks, and collecting soil, surface water, sediment, and residual waste 
material samples. Upon arrival, the EPA plugged the overflow pipe in 
the on-site retention pond to prevent contaminated water in the pond 
from flowing into Moncrief Creek. Once the on-site retention pond was 
stabilized, the plug was removed.
    In January 2011, the EPA conducted a removal investigation at the 
FSWT property. During the removal investigation, soil samples were 
collected from 17 residential properties, the STES and RVDES 
properties, and the FSWT property. Arsenic, chromium, and copper were 
detected in surface and subsurface soil samples collected from the FSWT 
property.
    In July 2011, the EPA conducted a removal confirmation and 
residential sampling event at the FSWT property. Removal activities 
included excavation of gravel and soil down to 1.5 feet below land 
surface (bls) along the northern, western, and southern portions of the 
property. Between March and October 2011, the EPA conducted removal 
activities at the FSWT property and the adjacent STES and RVDES shared 
playground.
    In May 2011, the EPA conducted a site assessment investigation at 
the FSWT property. During the investigation, soil samples were 
collected along the northern and western portions of the FSWT property, 
along the southern FSWT property boundary, beneath the concrete that 
covered the majority of the FSWT property, and from nearby residential 
properties. Groundwater samples were also collected from monitoring 
wells installed by Wood Treaters, LLC throughout the property and 
around the STES retention pond.
    The site was proposed to be on the National Priorities List (NPL) 
on March 15, 2012 (77 FR 15344), and was finalized on September 18, 
2012 (77 FR 57495).

Remedial Investigation and Feasibility Study (RI/FS)

    Between 2012 and 2013, the EPA conducted a remedial investigation 
(RI) and risk assessment to fully characterize site contaminants, fate 
and transport, and receptors for all exposure routes on and off-site. 
Based on the Human Health Risk Assessment (HHRA) and the Screening-
Level Ecological Risk Assessment (SLERA), unacceptable risks were 
estimated for non-residential and residential exposures to arsenic, 
copper, chromium, and polycyclic aromatic hydrocarbons (PAHs) on site. 
For off-site residential soils, the EPA believed that soils immediately 
adjacent to the FSWT property and nearby residential yards were 
contaminated by former wood treating operations conducted at the site. 
The HHRA determined that several residential yards exceed EPA's 
acceptable risk range. It was determined that the site-related 
contamination migrated due to stormwater runoff and spray from the 
tires of the trucks leaving the site from the south, east, and west. 
The EPA and FDEP decided to address all residential parcels that were 
impacted by site-related contamination and where arsenic concentrations 
are above the background concentration of 2.36 ppm.
    The SLERA also identified a risk for an avian receptor that may use 
the on-site retention pond as a primary food source and the sediments 
warrant a response action. Within Moncrief Creek, the major area of 
sediment contamination is located about 1,800 feet downstream of the 
discharge point of stormwater from the FSWT site to the creek. However, 
further investigation of stream sediments in Moncrief Creek located 
off-site was needed to determine if a response action is warranted to 
protect the environment. It was determined that if a response action 
was warranted, a focused feasibility study will be completed and the 
additional contaminated areas will be remediated as a second operable 
unit under the FSWT site.
    The Feasibility Study evaluated excavation and off-site disposal 
and with different treatment options for soils considered RCRA 
hazardous. The future anticipated land use is residential. Cleanup 
concentrations were developed to be protective of human health and are 
based on future anticipated land use.

Selected Remedy

    EPA chose excavation and off-site treatment and disposal as the 
best option for the remedial action at the site. The Record of Decision 
(ROD) was signed on August 22, 2017. The major components of the remedy 
included excavation of the 12.5 area parcel, sediment in the on-site 
retention pond, and off-site properties. In addition to excavation, the 
remedy included temporary storage of generated waste, off-site disposal 
at EPA approved landfills, backfilling and restoration activities. The 
Remedial Action Objectives were: (1) Prevent human exposure (direct 
contact and ingestion) to on-site soil with concentrations of COCs 
above levels protective of residential use; (2) Prevent migration of 
contaminated stormwater runoff from the FSWT site to adjacent 
properties and Moncrief Creek; (3) Prevent unacceptable risk to 
ecological receptors (benthic organisms and avian) from contaminated 
sediments and surface water in the on-site retention pond; (4) Prevent 
direct contact with residual waste material and contaminated building 
structures located on the site, including the drip pad and process 
containment areas; and (5) Prevent off-site residential human exposure 
(direct contact and ingestion) to soil with concentrations of arsenic 
above levels protective of residential use.

Response Actions

    In accordance with the ROD, a pre-design field investigation was 
performed to fill data gaps at the school property and at residential 
properties east of the FSWT Site for arsenic concentrations and to 
provide additional site-specific information needed to develop the RD.
    Three residential properties were sampled consistent with the RI 
sampling. Two of the properties exceeded the arsenic cleanup level.
    STES delineation soil samples were collected on March 20, 2018 and 
June

[[Page 36372]]

12 through June 14, 2018. Arsenic concentrations exceeded the cleanup 
level. The EPA and FDEP recognized the potential concern of the parents 
and community and worked together to address the impacted soil as soon 
as possible. Since the EPA did not have RA funding, FDEP mobilized, 
removed, and disposed of offsite the impacted soil during the summer 
break when students were not present. This facilitated a component of 
the selected remedy.
    Starting on July 9, 2018, the FDEP, started collecting additional 
soil samples for delineation of the area needing removal on the STES. 
Excavation activities occurred from July 16, 2018 through August 12, 
2018, and were completed in 25 days. Approximately 3,360 tons of soil 
was removed from the school property during the excavation activities. 
The excavated area was backfilled and restored.
    The Remedial Action began in February 2019 and construction 
activities were completed in October 2019. The 51 residential 
properties, the 12.5-acre property, and the on-site retention pond were 
remediated and restored. The EPA contractor excavated, stockpiled, and 
disposed of roughly 67,000 tons of excavated soils and sediments at EPA 
approved RCRA facilities. The EPA also collected confirmation samples 
from the floors and sidewalls of excavation areas and continued 
excavating soil if confirmation samples exceeded cleanup levels.
    In July 2019, the EPA collected sediment samples, fish, insects, 
and crayfish along Moncrief Creek to address uncertainties raised in 
the SERLA. The analyses of the data concluded that site-related 
contaminants (arsenic, copper, chromium) are not likely to be 
appreciable contributors to the toxicity levels observed in the 
sediment toxicity tests from sediment samples from the retention basin 
and that site-related metals contamination in the Moncrief Creek 
retention basin is not likely to cause appreciable or unacceptable 
risks to ecological receptors that may feed at the Moncrief Creek 
retention basin. Therefore, it was determined the EPA would not take a 
response action on Moncrief Creek.
    The completion of Remedial Action was documented in the Final 
Remedial Action Report and documented in a Superfund Remedial Action 
Completion memorandum signed on March 11, 2020 (Superfund Enterprise 
Management System (SEMS) document identification number 11143607). The 
reports and the memorandum are available in the deletion docket and 
they describe the cleanup techniques, cleanup concentrations for COCs, 
confirmation testing results, and QA/QC methodologies.

Cleanup Levels

    Except for arsenic, the cleanup levels for the on-site and off-site 
contaminated surface soils are based on FDEP's SCTLs for direct 
exposure and residential use (Florida Administrative Code [F.A.C.] 62-
777 Table II). These SCTLs are identified as chemical-specific ARARs. 
Neither EPA (as a policy matter) nor Florida set cleanup levels for an 
individual contaminant that is more stringent than the site-specific 
background concentration for that contaminant, provided that the 
background level is protective of human health and the environment. 
Therefore, the EPA used the site-specific background level of 2.36 ppm 
for arsenic instead of the FDEP SCTL. The cleanup levels for sediments 
are based on Florida's sediment quality assessment guidelines for the 
protection of sediment-dwelling organisms. The cleanup levels can be 
found in the Record of Decision (SEMS 11054367)

Operation and Maintenance

    Since the RA cleanup levels achieved unlimited use and unrestricted 
exposure (UU/UE), there is no need for Operation and Maintenance (O&M). 
However, the owner of the property should employ good housing keeping 
practices to ensure proper drainage of stormwater from the site and 
should include routine inspection of all site areas for evidence of 
positive drainage towards the site ditches and retention pond, routine 
mowing of site grass, routine removal of debris and vegetation other 
than grass from the ditches and retention pond, and routine inspection 
and removal of any debris, vegetation or other obstruction from the 
pond inlet structures and pipes.

Five-Year Review

    Hazardous substances, pollutants, or contaminants will not remain 
at the Site above levels that allow for UU/UE after completion of all 
remedial action construction. Therefore, a statutory five-year review 
under CERCLA Section 121(c) will not be required for this remedial 
action.

Community Involvement

    The EPA held numerous community meetings before and during the 
residential cleanup. The EPA issued fact sheets and maintained a public 
website during remedial construction. After the cleanup was complete, 
the EPA released final fact sheets and held a final availability 
session to highlight the accomplishment and answer any questions and 
concerns.
    All EPA documents are on the site's public website. A notice is 
being published in a major local newspaper, the Florida Times-Union and 
postcards have been sent out notifying the pubic of the deletion.

Determination That the Site Meets the Criteria for Deletion in the NCP

    The EPA has followed all procedures required by 40 CFR 300.425(e), 
Deletion from the NPL. The EPA consulted with the State of Florida 
prior to developing this document. The EPA determined that both the EPA 
and FDEP have conducted all appropriate response actions required and 
that no further response action for this portion of the Site is 
appropriate. The EPA is publishing a notice in a major local newspaper, 
The Florida Times-Union, of its intent to partially delete the Site and 
how to submit comments. The EPA placed copies of documents supporting 
the proposed partial deletion in the Site information repository; these 
documents are available for public inspection and copying.
    The implemented remedy achieved the degree of cleanup and 
protection specified in the ROD. The selected remedial action 
objectives and associated cleanup levels for the surface soil are 
consistent with agency policy and guidance. Based on information 
currently available to the EPA, no further Superfund response in the 
area proposed for deletion is needed to protect human health and the 
environment.
