SEVENTH FIVE-YEAR REVIEW REPORT
BAYOU SORREL SUPERFUND SITE
EPA ID#: LAD980745541
IBERVILLE PARISH,LOUISIANA
This memorandum documents the U.S. Environmental Protection Agency's performance, determinations, and
approval of the Bayou Sorrel Superfund Site (Site) seventh five-year review under Section 121(c) of the
Comprehensive Environmental Response. Compensation, and Liability Act, 42 U.S. Code Section 9621(c), as
provided in the attached seventh Five-Year Review Report.
Summary of the Seventh Five-Year Review Report
The site began operation as a hazardous waste landfill operated by the Environmental Purification Advancement
Cooperation (EPAC) in early 1977. Approximately 50 of the 265 acres were actually used for waste disposal.
Wastes were disposed in two sludge pits, four liquid waste ponds, two drum burial cells (one crushed drum/one
filled drum), and one landfarm area. The facility has been closed since the summer of 1978. EPA selected a
remedy to address site contamination in a 1986 Record of Decision (ROD). The ROD included the follow ing
elements:
Minimize the threat to public health, if any, from use of or contact with onsite surface water bodies,
which include the lake and small pond, as well as the back swamp in the wet season. Protect the
environmental quality of these water bodies from degradation due to contaminants;
Minimize the threat to public health from use of or contact with off-site surface water bodies which
include the back swamp, the Upper Grand River. Grand River. Pat Bay. and Pat Bayou, and protect the
environmental quality of these water bodies from degradation due to contaminants;
Minimize the threat to public health from direct use of the shallow groundwater and protect the quality of
the Plaquemine Aquifer and surface water bodies which might receive discharges from the shallow
groundwater;
Minimize adverse effects of present and potential users of the Plaquemine Aquifer from contaminants
migrating from the site;
Isolate contaminated materials from direct contact with surface soils and sediments to minimize migration
of contamination; and
Limit the potential for air releases from the site that would have adverse effects on human health and limit
onsite concentrations of hydrogen sulfide, cyanide, and other hazardous air pollutants to within OSHA
standards.
The Site's potentially responsible party (PRPs). the Bayou Sorrel Steering Committee (BSSC). constructed the
EP A remedy selected in the ROD betw een 1989 -1990. Long-term monitoring of hazardous substance
concentrations in the capped landfill areas is ongoing. A Servitude Agreement and Declaration of Restriction for
the site exists between the landowners and the BSSC that restricts unauthorized access and use of the site and
surrounding property. No future land uses (other than post-construction Operations & Maintenance monitoring)
are anticipated by the BSSC at this time. This Five-Year Review (FYR) assessed the Site's vulnerability to the
effects of climate and weather hazards. The Site lies entirely within the 100-year floodplain. and protectiveness of
the remedy may be vulnerable to potential impacts of climate change (see Section V, Question C for more
information). A climate vulnerability assessment is recommended to be completed prior to the next five-year
review.
The EJScreen report identifies no EJ Indexes that exceed the 80th percentile at the national and state average level.
In addition, the community has not self-identified as an environmental justice community. The EJScreen report is
included in Appendix J.

I. INTRODUCTION
The purpose of a five-year review (FYR) is to evaluate the implementation and performance of a remedy to
determine if the remedy is and will continue to be protective of human health and the environment. The methods,
findings and conclusions of reviews are documented in FYR reports such as this one. In addition. FYR reports
identify issues found during the review, if any, and document recommendations to address them.
The U.S. Environmental Protection Agency (EPA) is preparing this FYR pursuant to the Comprehensive
Environmental Response. Compensation, and Liability Act (CERCLA) Section 121. consistent with the National
Contingency Plan (NCP) (40 CFR Section 300.430(f)(4)(ii)) and considering EPA policy.
This is the seventh FYR for the Bayou Sorrel Superfund Site (the Site). The triggering action fortius statutory
review is the completion of the sixth FYR. dated July 10, 2018. The FYR was prepared due to the fact that
hazardous substances, pollutants, or contaminants remain at the site above levels that allow for unlimited use and
unrestricted exposure (UU/UE).
The Site is considered under one sitewide distinction and does not consist of individual operable units (OlJs). and
thus will be addressed sitewide in this FYR.
The Bayou Sorrel Superfund Site FYR was led by Brian Mueller and Jason McKinney (EPA - Region 6).
Participants included Laurie Peacock (LDEQ - Remediation). Ken Rike (BSSC - Chairman), kelli Hardest}
(ERM - Geologist/Partner-in-Charge). and Emily Bryan (ERM - Geologist/Project Manager). The PRP Group
and local community were notified of the initiation of the five-year review, which began on November 16. 2022.
Site Background
As shown in Figure 1 of Appendix C, the Site is located in Iberville Parish. Louisiana, approximately 20 miles
southwest of Baton Rouge (not shown on the figure), and about six miles northwest of the town of Bayou Sorrel.
The Site is a "T" shaped, relatively flat parcel of land encompassing about 265 acres, of which about 50 acres
were used for waste disposal. The waste disposal areas consisted of four landfills including a spent lime cell and a
crushed drum cell, four covered liquid waste ponds, and one land farm. The Site has vegetative cover consisting
mostly of trees and grass and is bound by rivers, bayous, and swamp land. Currently there are no industrial
workers onsite and there are no residences near the Site. There are structures near the Site that are used
infrequently for recreational purposes, such as fishing.
The site began operation as a hazardous waste landfill operated by the Environmental Purification Advancement
Cooperation (EPAC) in early 1977. Wastes were disposed in two sludge pits, four liquid waste ponds, two drum
burial cells (one crushed drum/one filled drum), and one landfarm area. The facility has been closed since the
summer of 1978. A Servitude Agreement and Declaration of Restriction for the site exists between the
landowners and the Bayou Sorrel Steering Committee (BSSC) that severely restricts unauthorized access and use
of the site and surrounding property. No future land uses (other than post- construction operation and
maintenance (O&M) monitoring) are anticipated by the BSSC at this time.
Appendix A includes a list of documents review ed during this FYR. Appendix B includes a timeline chronology
of Site events.

FIVE-YEAR REVIEW SUMMARY FORM
II. RESPONSE ACTION SUMMARY
Basis for Taking Action
A December 1985 Endangerment Assessment, prepared by EPA contractors, concluded that the most significant
endangerment to human health at the site was direct contact with hazardous wastes at the site. Unrestricted access
to the site by hunters, fishermen and petrochemical workers, coupled with documented contamination of the soils
at the site and evidence of seeps around the waste disposal areas was sufficient to support a finding of potential
endangerment to human health from direct contact with contaminants at the site. The potential also existed for
both surface and subsurface contaminant migration and subsequent contamination of groundwater and surface
waters at the site. The potential for surface water contamination of the swamp to the south of the site and other
adjacent water bodies (Upper Grand River. Pat Bayou and the Borrow River and Lake) could result from overland
flow of contaminated runoff or flood waters from the site and subsurface migration of contaminants from the site
into the groundw ater. Thus, the potential existed for human exposure to contaminants by the ingestion of aquatic
life, incidental ingestion or by dermal exposure from these potentially contaminated waters. However, the
expected intake of contaminants via these pathw ays was expected to be minimal, both because of limited
exposure to the potentially contaminated areas and limited extent if migration did occur.

Record of Decision
The Acting Regional Administrator signed the Record of Decision (ROD) for the Site on November 14, 1986.
The overall Remedial Action Objective (RAO) is the protection of public health, welfare, and environment.
However, site-specific remedial objectives were established prior to the collection of Remedial Investigation (Rl)
data for the receptor media identified at the site. The Feasibility Study (FS) developed the follow ing objectives:
Minimize the threat to public health, if any, from use of or contact with onsite surface water bodies,
which include the lake and small pond, as well as the back swamp in the wet season. Protect the
environmental quality of these water bodies from degradation due to contaminants;
Minimize the threat to public health from use of or contact with off-site surface water bodies which
include the back swamp, the Upper Grand River. Grand River. Pat Bay. and Pat Bayou, and protect
the environmental quality of these water bodies from degradation due to contaminants;
Minimize the threat to public health from direct use of the shallow groundwater and protect the
quality of the Plaquemine Aquifer and surface water bodies which might receive discharges from the
shallow groundwater;
Minimize adverse effects of present and potential users of the Plaquemine Aquifer from contaminants
migrating from the site;
Isolate contaminated materials from direct contact with surface soils and sediments to minimize
migration of contamination; and
Limit the potential for air releases from the site that would have adverse effects on human health and
limit onsite concentrations of hydrogen sulfide, cyanide, and other hazardous air pollutants to within
OSHA standards.
Based on the data collected, active remediation was not required to meet all of the objectives. The objectives
served as the basis for the environmental assessment in the remedial alternatives evaluation. By combining the
applicable remedial action technologies and considering the pathw ays of migration in accordance with the then
existing regulations (40 CFR 300.68(f)), 13 remedial alternatives were developed for the Bayou Sorrel Site.
It was determined that controlling the source of contamination would reduce the endangerment to human health
and the environment, such that ingestion or contact was no longer possible. The ROD and subsequent remedial
design included the follow ing:
9
-------
Regrading of the Site to control runoff thus limiting erosion of the existing soil layers covering the waste
areas, limiting surface water ponding, and diverting storm water from waste areas;
Covering former waste disposal areas with RCRA topsoil/geomembrane/clay caps, regardless of their
current condition resulting from the closure activities conducted in 1979;
Installing a sand/geofabric porewater drainage layer (above the wastes and below the caps) connected to a
system of pipes, manholes, pumps, and tanks to collect and store any liquids from this layer;
Installing a gas venting system in the caps to reduce the accumulation of methane and other gases beneath
the caps;
Consolidating all miscellaneous wastes outside existing covered waste disposal areas under the new caps
for grading and fill purposes;
Installing a slurry wall approximately 30 feet deep (keyed into the underlying natural clay layer found at
that depth) around the former landfill area (South Area Cap) and installing a shallower slurry wall around
the former Pond 4 area (North Area Cap);
Installing fences around all new ly capped areas to restrict access to the disposal areas and constructing
gravel access roads around the fenced areas to allow continued recreational use of adjacent lands and the
borrow lake while diverting traffic around and away from the disposal areas; and
Installing a groundwater monitoring system to monitor the effectiveness of the remedy.
Status of Implementation
Negotiations betw een EPA and a PRP Steering Committee, through much of 1987, resulted in the signing of a
Consent Decree (CD), effective March 17. 1988, that required the PRPs to conduct the Remedial
Design/Remedial Action and O&M in accordance with the ROD. The CD contained a statement of work (SOW)
that described the necessary tasks to be completed to comply with the objectives of the ROD.
While the CD does not require institutional controls, a Servitude Agreement and Declaration of Restriction for the
site exists between the landowners and the BSSC that severely restricts unauthorized access and use of the site
and surrounding property. The Servitude Agreement dated September 15, 1987, was filed in Iberville Parish in
Conveyance Book 417, Entry 204. Additionally, the BSSC has a 99-year lease on the site with property
landowners, also dated September 15, 1987, filed in Iberville Parish, in Conveyance Book 417, Entry 205. The
CD is an exhibit to the lease. This Servitude Agreement instrument, the BSSC's 99-year lease of the property and
the site CD limit property access to the BSSC and their contractors, the EPA. and the LDEQ.
The EPA approved SOW for Remedial Design (RD). submitted by the PRPs on July 15, 1987, outlined the pre-
design activities, the design elements, and the deliverables. The final, approved RD was outlined in two separate
documents. Remedy construction was planned for the 1989 and 1990 construction seasons after pre-construction
site preparation work at the Site, which began in July 1988, was completed.
During the first construction season. April through November of 1989, the follow ing remedial construction
activities were completed:
Slurry walls around the North and South Areas - The trenching, slurry mixing and backfilling were
conducted around both former waste areas in accordance with approved specifications. The only
deviation from the original plans was in a small portion of the South Area, where slight modifications
(approved by EPA) in the slurry wall construction methods eliminated sloughing problems that occurred,
due to unusually heavy rains and slightly differing geotechnical conditions that were encountered in that
area.
Porewater Collection Svstem - Construction of the porewater collection trenches, collection lines,
geofabric. and storage manholes was completed in accordance with the plans and specifications.
10
-------
Clav Caps - Follow ing initial contouring with attic fill, the base clay cap lift (24 inches thick) was
installed at both the North and South areas. The attic fill, clay materials, placement methods, and
compaction requirements were all compliant with the plans and specifications. It was initially planned to
place a temporary layer of topsoil on this base lift of clay for protection during the off-season. The
temporary topsoil layer was deemed unnecessary, however, and not installed because full demobilization
did not occur, leaving equipment and manpower available to respond to any erosion problems
encountered between the construction seasons.
During the second and last construction season. April through September 1990, the follow ing remedial
construction activities were completed:
Final Clav Lift - The final clay lift of the cap was installed. Clay materials, placement, compaction and
preparation of the clay caps were all completed in accordance with the plans and specifications. The caps
were prepared as smooth surfaces, free of irregularities (sticks, rocks, etc.). for placement of the overlying
geomembrane.
Gas Venting Svstem. Geomembrane Laver. Sand Laver. Topsoil - Materials and placement of the 30 mil
geomembrane, the surface water drainage layer of sand (6 inches thick), and the topsoil layer (12 - 18
inches thick) were conducted at both the North and South Cap Areas in accordance with the plans and
specifications. Modifications in the materials and placement of the gas vent system were necessary
because the slots in the gas vent pipe were different than originally designed. Because of this minor
difference, concerns were raised about the possibility that the overlying geomembrane would cover the
slots and prevent any accumulated gas from entering the pipes. Therefore, the gas vent piping was placed
in a pea gravel bed to provide a space between the top of the piping and the geomembrane, which will
allow space for gas to enter the piping.
Pore water Irrigation Svstem - The original plans called for the off-site disposal of pore water generated
from the settling of the unconsolidated clays in the caps. At the time of the preparation of the final CD. it
was anticipated that pore water, based on its composition, might not be able to be managed onsite. Initial
monitoring of this pore water, both during and after construction of the caps, has shown that it has
consistently met State storm water discharge standards; therefore, an alternate, on site irrigation discharge
system was proposed by the PRPs and approved by EPA. This system will spray any generated
pore water onto the vegetative cover of the cap to provide moisture during dry periods.
General Engineering - Seeding of the newly covered clay caps, access road construction, and fencing of
the site were completed in accordance with the plans and specifications.
Monitoring Wells - In accordance with the CD. a total of 43 monitoring wells were installed at the site.
15 in the North Area, and 28 in the South Area. The monitoring wells were constructed in accordance
with the Remedial Concept Design Addendum to the approved Bayou Sorrel SOW and were approved by
EP A and the State. New groundw ater data is being compared to the statistics of historical groundw ater
data. This is the "trigger mechanism" referred to in the ROD.
As required by the CD. the PRPs submitted a draft Remedial Action (RA) Report on October 30, 1990. The final
RA Report was formally approved on April 16. 1991, after a joint EPA and LDEQ inspection indicated that the
requirements for conducting the Remedial Action had been met. This inspection, conducted on March 25 & 26,
1991, was the first Semi-Annual Engineering Inspection required as part Construction O&M Plan.
The EPA and the State determined that all areas of concern described in the NPL listing of the Bayou Sorrel Site
had been adequately addressed in the Site Close Out Report dated May 26, 1992. A stringent O&M and
groundwater monitoring program was established to ensure that protectiveness is maintained in the future; the site
is currently in post-construction year (PCY) 33 for O&M and groundwater monitoring activities.
11
-------
On January 15, 1997, Jon D. Rauscher. Ph.D.. EPA Toxicologist. concluded that arsenic detected in the
groundwater at the site appeared to be naturally occurring and recommended that the delisting of this Site from
the NPL proceed.
Institutional Control (IC) Review
The site CD does not require institutional controls. A Servitude Agreement and Declaration of Restriction for the
site exists between the landowners and the BSSC that severely restricts unauthorized access and use of the site
and surrounding property. This Servitude Agreement is effective for a minimum of 99 years and a ROD
Amendment or Explanation of Significant Difference (ESD) may be needed upon expiration of the Servitude
Agreement.
Systems Operations/QAM
Groundwater sampling activities have been conducted in accordance with the EPA-approved Sampling and
Analysis Plan (S&AP), April 13, 2021, which is based on the requirements outlined in the Quality Assurance
Project Plan (QAPP), April 24, 1989. The S&AP is revised on a frequent basis primarily to establish specific
sampling schedules. The analytical parameters were selected based on negotiations conducted prior to issuance of
the ROD and the constituents know n to be present onsite.
In a letter to EP A and LDEQ dated April 10, 2015, on behalf of BSSC. ERM informed the aforementioned parties
of the removal of three (3) non-priority pollutant constituents from the 5-year analysis suite due to the laboratory
indicating that they could no longer analyze for these 3 non-priority pollutants as Tentatively Identified
Compounds (TICs). as in the past. Pace Analytical Services. Inc.. historically utilized for Bayou Sorrel Site
sampling event analysis, does not have the standards and software to measure norflurazon. 3-(trifluoromethyl)-
benzeneamine and 1.2-benzene dicarboxylic acid via TICs. as has been the method of analysis in previous
sampling events. Additionally, the laboratory was not able to find an LDEQ-accredited laboratory in which to
subcontract for groundwater sample analysis of these constituents via TICs.
In 2016, a Long-Term Monitoring Optimization (LTMO) Report was developed by HydroGeo Logic. Inc.. which
provided recommended modifications to sampling monitor wells, sampling frequency, analytical parameters,
statistical analysis, etc. The LTMO review process included qualitative review of the conceptual site model,
statistical analysis, and a decision-logic based review of Site data using the Monitoring and Remediation
Optimization System (MAROS) software. Sampling results from individual wells were also evaluated using
statistical methods encoded in ProlJCL 5.0. Guidance on design and interpretation of statistical data was taken
from the U .S. EPA Statistical Analysis of Groundw ater Monitoring Data at RCRA Facilities Unified Guidance
(2009).
ERM submitted the LTMO recommendations to the EPA/LDEQ on April 1 1. 2016. The EPA reviewed the report
pursuant to Section VIII of the CD and provided comments and approval of the LTMO proposed
recommendations via electronic communications on June 8 and 14, 2016.
In September 2020, ERM submitted a proposal of long-term modifications to the Bayou Sorrel monitoring
program for PCY 3 1 and thereafter. The BSSC provided additional information and formally requested to modify
the groundwater, pore water, and storm water sampling programs at the Bayou Sorrel Site in a letter dated
December 15, 2020. The EPA and LDEQ provided a joint response to these recommendations on February 23,
2021, conditionally approving modifications to the storm water and pore water sampling programs; however, the
proposed revisions to the groundwater sampling network were not approved (e.g., changes to DW-1). The BSSC
provided a revised recommendation on March 31, 2021, per EPA and LDEQ request. The revised
recommendations were approved by the US EPA on April 27. 2021. The following modifications have been
incorporated into the program as of the PCY 3 1:
Discrete sampling of pore water chambers for indicator parameters of total dissolved solids, total organic
carbon. pH. and specific conductance is no longer required.
12
-------
The porewater composite sample is analyzed for benzene only.
The frequency of storm water sampling has been reduced to occur only during the Five Year Review
sampling event.
Sampling parameters for storm water have been modified to be consistent with groundwater parameters.
Semi-annual cap settlement surveys are no longer required. The cap surface will continue to be inspected
visually after mowing.
The required frequency of site inspections has been reduced from weekly to quarterly.
The frequency of inspection and maintenance reporting has been reduced from semi-annually to annually.
Additionally, the EPA requested that BSSC evaluate the condition of the deep groundwater monitoring well
located on the South Cap. DW-1. due to previous and unsuccessful sampling attempts. The well was assessed,
redeveloped, and sampled during the PCY 32 and will continue to be monitored in accordance with the O&M
Plan.
Per LDEQ and US EPA approval, the upgradient wells (UW-1S, UW-2S, UW-1N, and UW-2N) were plugged and
abandoned on April 14, 2022, in accordance with the LDEQ and Louisiana Department of Transportation and
Development (LDOTD) Construction of Geotechnical Boreholes and Groundwater Monitoring Systems
Handbook.
Ongoing O&M activities continue to be conducted in accordance with the O&M Plan. These activities include:
At least quarterly site inspections by the Site caretaker;
Maintenance of vegetative cover and mowing the Site as needed;
Visually inspecting the surface of the caps after mowing and significant flooding events for signs of
erosion, ponding, and disruption of proper drainage patterns;
Collecting porewater level measurements;
Inspecting and maintaining the components of the porewater collection and monitor well systems; and
Amending any significant deficiencies to the Site access roads by regrading or filling with limestone.
Overall, the site remains in very good condition with no significant maintenance or operational deficiencies. No
issues were identified during the FYR site inspection that would indicate potential remedy failure.

IV. FIVE-YEAR REVIEW PROCESS
Community Notification, Community Involvement and Site Interviews
Representatives from the EPA, LDEQ, BSSC. and ERM conducted a site visit and evaluation on November 29,
2022.
A public notice was made available by publication in the Post South, a weekly new spaper based in Plaquemine.
Louisiana on November 17. 2022, and in the Baton Rouge Advocate on November 16. 2022, stating that there
was a five-year review and inviting the public to submit any comments to the U.S. EPA. Proof of publication and
copies of the public notices are included in Appendix D. A period of at least 30 days was allowed to pass prior to
finalizing this Seventh FYR Report. No comments were received. The results of the review and the report will be
made available at the Site information repository located in Plaquemine. Louisiana at the city public library.
24605 J Gerald Berret Blvd. Plaquemine. LA 70764.
Public Notices will be sent to both of the aforementioned newspapers informing the community that the Seventh
FYR of the Site has been conducted and will list a contact name and telephone number for further information.
This notice will inform the community that the Seventh FYR of the Site is complete and that the results of the
review and the report are available at the Bayou Sorrel Public Repository located in Plaquemine. Louisiana at the
city's public library.
During the FYR process, interviews were conducted to document any perceived problems or successes with the
remedy that has been implemented to date. The results of these interviews are summarized below. The
interviewees included:
Ms. Emily Bryan, Environmental Resources Management (consultant to the BSSC);
Ms. Laurie Peacock. Louisiana Department of Environmental Quality; and
Mr. James Rike. PRP Group Chairman.
The individuals interviewed expressed no concerns with the operation and maintenance of the Site. All
individuals interviewed support that the Site continues to be protective of human health and the environment.
Data Review
This section provides a summary of the analytical history of the site, from completion of the fifth Five-Year
Review Report, dated July 10, 2018 through May 3 1. 2022, as well as a summary of continued O&M activities at
the site. This summary includes the groundwater data collected up to and including the PCY 32 annual
monitoring event. The annual groundwater sampling event for PCY 33 was conducted in May 2023. All of the
existing data, collected as part of the post-construction O&M program, are located in the Site file at the US EPA
Region 6 in Dallas. Texas. The file is continually updated and copies of select files are available for review in the
Bayou Sorrel Public Repository located in Plaquemine. Louisiana at the city public library.
14
-------
Groundwater sampling activities have been conducted in accordance with the EPA-approved S&AP, which is
based on the requirements outlined in the QAPP. The S&AP is revised on a frequent basis primarily to establish
specific sampling schedules. The analytical parameters were selected based on negotiations conducted prior to
issuance of the ROD and the constituents known to be present onsite. Per recent changes in the S&AP via the
15
-------
LTMO Report and EPA recommendations, a groundwater statistics report is generated subsequent to a five-year
sampling event, which statistically relates the changes in groundwater quality over time.
All corroborating groundwater, storm water, and pore water data from the fourth quarter of PCY 2 (at the latest)
through PCY 32 are summarized in Appendix H. Tables 1 - 4. Table 1 presents the results for the groundw ater
indicator and water quality parameters from monitoring wells installed to monitor the North Area cap. Table 2
presents the results for the groundwater indicator and water quality parameters from monitoring wells installed to
monitor the South Area cap. A review of the groundwater data collected through PCY 32 continues to indicate
that the remedy selected for the Site remains protective of human health and the environment. As reported in the
statistical evaluation performed during PCY 32:
The arsenic concentrations which have been reported at the Bayou Sorrel Site have been higher than the
MCL at areas of the Site where no historical waste handling activities have been known to occur;
The shallow groundwater conditions at the Site are such that there are no potential receptors for
groundw ater with arsenic present;
The presence of arsenic at higher levels than those found at the Site have been documented at numerous
other locations in south Louisiana (including areas in geographic proximity to the Bayou Sorrel Site); and
Observed differences for water quality parameters are measured in a shallow aquifer that does not meet
primary or secondary water quality standards, nor is the groundwater used for potable supply.
Therefore, although results of the statistical evaluation performed during PCY 32 concluded some statistically
significant differences and trends exist, there is no potential long- or short-term threat from groundw ater.
Table 3 of Appendix H presents the results for the analysis of pore water indicator and water quality parameters.
Samples from each porewater chamber are analyzed for pH. specific conductivity, and temperature. A flow-
weighted composite sample of porewater chambers 1-9 was analyzed for total dissolved solids, and total organic
carbon. Based on the results of the engineering evaluation, pumping activities for the porewater collection
chambers system were suspended during 1996. The BSSC decided to reinstate operation of the porewater
management system in 1997 in the manner that it was operated prior to the evaluation period. Porewater pumped
from the porewater management system is used to irrigate the caps during dry periods.
In accordance with the EPA approval of long-term program modifications, as of the PCY 31, discrete sampling of
porewater chambers for indicator parameters of total dissolved solids, total organic carbon. pH. and specific
conductance has been discontinued, and the porewater composite sample is analyzed for benzene only.
The frequency of storm water sampling has been reduced to occur only during the FYR sampling
event.
Sampling parameters for storm water have been modified to be consistent with groundwater parameters
Table 4 of Appendix H presents the results for the analysis of storm water indicator and water quality parameters.
Storm water sampling requirements are found in the 1988 O&M Plan that required a frequency of one sampling
per five years. Storm water sampling is conducted in conjunction with the schedule established for groundwater
monitoring at the site; how ever, if a storm event does not occur (w eather conditions documented) during the
groundwater monitoring event, storm water sampling will be postponed until the next scheduled sampling event.
A storm event took place during the groundwater sampling event for PCY 5 in 1995; those results are found in
Table 4. The next scheduled storm water sampling event was scheduled for PCY 10 in 2000. No storm event
occurred during the scheduled groundwater monitoring events for PCY 10 through PCY 31.
In accordance with the EPA approval of long-term program modifications, as of the PCY 3 1. the frequency of
storm water sampling has been reduced to occur only during the FYR sampling event, and sampling parameters for
storm water have been modified to be consistent with groundwater parameters. A storm water sampling event
occurred during the FYR sampling event in PCY 32, and the results of that sampling

are included in Table 4.
Site Inspection
The inspection of the Site was conducted on November 29, 2022. In attendance were Brian Mueller and Jason
McKinney (EPA - Region 6). Participants included Laurie Peacock (LDEQ - Remediation). Ken Rike (BSSC -
Chairman), kelli Hardest} (PIC - Geologist/Partner-in-Charge), and Emily Bryan (PM - Geo 1 ogist/Project
Manager). The purpose of the inspection was to assess the protectiveness of the remedy. The site inspection
checklist is included in Appendix E. Site inspection photographs are included in Appendix G. The following
observations were made during the site inspection:
One bollard was collapsed and others need to be righted at South Cap and well labels need to be checked and
replaced where necessary at North Cap. No issues were identified during the FYR site inspection that would indicate
potential remedy failure.
V. TECHNICAL ASSESSMENT
QUESTION A: Is the remedy functioning as intended by the decision documents'.'
Question A Summary:
Yes. based on a review of Site documents, the data review and observations made during the Site inspection, the
remedy appears to be functioning as designed.
Remedial Action Performance
The review of documents, risk assumptions, and the results of the site inspection and monitoring indicate that the
remedy is functioning as intended by the ROD. While the ROD requirements addressed human health risk
management, the remedy also remains protective of ecological receptors. The capping of contaminated wastes
and soils and containment through installation of the slurry walls has achieved the remedial objectives to
minimize the migration of contaminants to groundwater and surface water and prevent direct contact with, or
ingestion of contaminants by human or ecological receptors. The cap's topsoil layer and sand layer also prevent
potential ecological exposure to waste material.
System Operations/O&M
Maintenance of the North and South area caps and drainage features has been effective. One bollard was
collapsed and others need to be righted at South Cap and well labels need to be checked and replaced where
necessary at North Cap. No issues were identified during the five-year review site inspection that would indicate
potential remedy failure. Routine monitoring of groundwater provides a triggering mechanism whereby frequent
sampling and analysis of the wells is used to identify any sudden degradation of the quality of the area's
groundwater before potentially affected materials can migrate offsite. The remedy of capping, slurry walls,
hydraulic controls, and containment is functioning as designed. Contaminants in the storage cells is wholly
contained and not observed outside the cells. The containment is judged to be effective. O&M annual costs are
consistent with original estimates and there are no indications of any difficulties with the remedy.
Implementation of Institutional Controls and Other Measures
While the CD does not require institutional controls, a Servitude Agreement and Declaration of Restriction for the
site exists between the landowners and the BSSC that severely restricts unauthorized access and use of the site
and surrounding property. The Servitude Agreement dated September 15, 1987, was filed in Iberville Parish in
Conveyance Book 417, Entry 204. Additionally, the BSSC has a 99-year lease on the site with property
landowners, also dated September 15, 1987, filed in Iberville Parish, in Conveyance Book 417, Entry 205. The
CD is an exhibit to the lease. This Servitude Agreement instrument, the BSSC's 99-year lease of the property and
the site CD limit property access to the BSSC and their contractors, the EPA. and the LDEQ.
17
-------
The fencing, signs, and other access controls are adequate to maintain site security. The site location is remote and
both vehicular and pedestrian traffic is infrequent.
QUESTION B: Are the exposure assumptions, toxicity data, cleanup levels and RAOs used at the time of the
remedy selection still valid'.'
Question 6 Summary:
There have been no changes in the physical conditions of the site that would affect the protectiveness of the
remedy.
Changes in Standards and TBCs
The ROD identified the Resource. Conservation, and Recovery Act (RCRA). 42 U.S.C. Section 6901 et. seq.. as
the primary Applicable or Relevant and Appropriate Requirements (ARARs) governing remedial activities at the
Site. Specifically, the ROD states that the selected remedy would comply with RCRA capping requirements, as
well as all other applicable or relevant and appropriate standards, requirements, criteria, or limitations per Section
121(d) of CERCLA. There were no chemical specific ARARs identified by the ROD. There have been no
changes in these ARARs and no new standards or TBCs affecting the protectiveness of the remedy.
Changes in Toxicity and Other Contaminant Characteristics
The arsenic MCL in drinking water has changed from 50 ppb to 10 ppb; however, the remedy required in the
ROD is still protective. As stated previously, in a memorandum from Jon D. Rauscher. Ph.D.. EPA Toxicologist.
dated January 15, 1997, Dr. Rauscher concluded that arsenic detected in the groundwater at the site appeared to
be naturally occurring. The remedy of containment prevents contaminant migration, so the remedy is still valid.
There are no know n changes in toxicity factors or contaminant characteristics at the site. The assessment of risk
remains valid, and the remedy is functioning as designed. There have been no changes in risk assessment methods
or guidance that should affect the protectiveness of the designed remedy. There have been no notable changes in
land use on or near the site and no new routes of exposure have developed for the site. The suite of contaminants
remains the same as before, with no new toxic byproducts. Site conditions remain unchanged.
QUESTION C: Has any other information come to light that could call into question the protectiveness of the
remedy'.'
This FYR assessed the Site's vulnerability to the effects of climate and weather hazards. This site is located
within the 100-year floodplain and protectiveness of the remedy may be vulnerable to potential impacts of climate
change. A climate vulnerability assessment is recommended to be completed prior to the next five year review.

Thanksgiving on the cheap: Try these affordable dishes for the holiday
Mackensy Lunsford
If 2022 has taught us one thing, it's that we haven't
yet seen the end of the food supply chain woes.
Irifl at ion, avian flEu and market-shaking employ-
ment shifts have all combined to make your supermar-
ket trips a bit dicey. And yet, it's time for the holiday
season, when your budget seems stretched thinner
than the feathers on a turkey neck.
If you're dead set on the turkey for Thanksgiving
dinner, your options might look somewhat limited. In a
normal year, a smart consumer might get a small tur-
key, serve it with plenty of sides and guard the meat
with the carving fork. You're out of luck there. That's
because smaller turkeys may be harder to source in the
grocery store this year, a result of lingering processing
bottlenecks.
Thanksgiving turkeys of all sizes may be harder to
fiflnd and more expensive this year thanks to the spread
of the avian Ma. and inflQ&tion, USA Today reports. As
food prices soar across the nation, a recent Consumer
Price Index report showed the cost of uncooked poul-
try, including turkey, rose 17% in September from the
same month last year.
Think you 11 spring instead for turkey breast this
year? Think again if you're pinching pennies. The re-
tail price for fresh boneless and skinless turkey breast
Linton Hopkins basting a turkey with drippings and
butter. COURTESY OF HOPKINS & COMPANY
reached a record high of $6.70 per pound in Septem-
ber, 112% higher than the same time last year, accord-
ing to an American Farm Bureau Federation analysis.
USA Today says avian ffclu is also a factor, with poultry
producers in 43 states reporting impacts.
None of that is particularly cheery, so well focus on
the solutions. Those include ordering pizza (we kid,
but some news outlets have suggested it) and giving
meat a supporting role on your Thanksgiving table.
Here are some ideas:
How to save money at Thanksgiving
h Try main dishes where meat is used as a condi-
ment or mixed with other ingredients. Think shep-
herd's pie or chicken pot pie for elegant but affOordable
mains.
h Try smaller cuts. If you can fi nd affPordable turkey
breast, for example, you can brine and roast it until it's
perfectly tender. No dried bird breast this year.
h Try a diffDerent bird altogether. It's hard to imagine
anyone complaining about a perfectly smoked chicken
with crispy skin, for example.
h If it's not going to spur an outright revolt at din-
nertime, consider skipping meat, period. Vegetarian
"roasts" and other plant-based proteins abound in the
freezer section of most well-stocked grocery stores.
h Think outside of the box and mix and match eco-
nomical proteins, such as sausages and deep-fried
chicken. It's physically impossible to complain when
the smell of fried chicken is wafting through the air.
h Fill them up: carbs, carbs and more carbs. Load
the table with comforting casseroles and perfect
mashed potatoes, and you can get away with serving
much less meat. As an added bonus, youll get a zip of
energy to help combat the turkey tired phenomenon.

vertical barrier walls. The remedy is designed to inhibit the migration of wastes by providing a barrier to shallow
groundwater flow and to prevent physical contact with materials.
The following observations were made during the site inspection conducted on November 29. 2022:
E-l
-------
One bollard was collapsed, and others need to be righted at South Cap and well labels need to be checked and
replaced where necessary at North Cap.
~ All required wells located ~ Needs Maintenance ~ N/A
B. Adequacy of O&M
Describe issues and observations related to the implementation and scope of O&M procedures. In particular,
discuss their relationship to the current and long-term protectiveness of the remedy.
Based on the site inspection and review of Site documents, operation and maintenance of the site appears to be
adequate.
C. Early Indicators of Potential Remedy Problems
Describe issues and observations such as unexpected changes in the cost or scope of O&M or a high frequency of
unscheduled repairs that suggest that the protectiveness of the remedy may be compromised in the future.
No issues were identified during the five-year review site inspection that would indicate potential remedy failure.
D. Opportunities for Optimization
Describe possible opportunities for optimization in monitoring tasks or the operation of the remedy.
Optimization actions were completed in 2016.

1. What is your overall impression of the project, including cleanup, maintenance and reuse activities (as
appropriate)?
It is ERM's opinion that the project implementation is successfully progressing according to
agency-approved plans. The Site is well maintained, inspected according to schedule, and the
remedy effectiveness evaluated as required. The remedy is in good condition and project activities
are compliant with the Consent Decree. Eagle Environmental manages the regular O&M activities
associated with the Site (e.g., vegetation management, property maintenance, cap survey, etc.).
ERM manages the groundwater, porewater and storm water sampling, reporting and statistical
analysis.
2. What is your assessment of the current performance of the remedy in place at the Site?
Based on Site observations and our review of the data, we conclude that the Site continues to be
protective of human health and the environment, which supports that the remedy has been and
continues to perform at a satisfactory level.
3. What are the findings from the monitoring data? What are the key trends in contaminant levels that are being
documented over time at the Site?
The findings from the PCY32 monitoring data are consistent with historical analytical data.
Parameters with reported detections above the laboratory's limits of quantitation (LOQs) are
either below their respective Louisiana Department of Environmental Quality (LDEQ) Risk
Evaluation/Corrective Action Program (RECAP) groundwater screening standards or considered
to be within accepted regional background concentration levels.
Key trends in contaminant levels are evaluated through a Ground Water Statistics Plan
(GWSP), which is now performed every five years, in accordance with the Consent
Decree and Statement of Work for the Site. The recent groundwater statistics report noted a
statistical difference existed between the compliance wells and background wells on the North Cap
for arsenic (2 wells).
F-3
-------
Arsenic concentrations are within regional background and consistent with historical Site
concentrations. Although these differences and trends have been observed, there is no potential
long-term or short-term threat to human health or the environment from the groundwater at the
Site.
4. Is there a continuous on-site O&M presence? If so, please describe staff responsibilities and activities.
Alternatively, please describe staff responsibilities and the frequency of site inspections and activities if there
is not a continuous on-site O&M presence.
All activities are conducted in accordance with the Site's approved O&M Plan. ERM is
responsible for conducting the annual groundwater monitoring, drafting necessary annual
reports (e.g., groundwater monitoring and statistical analysis), and communicating with the
Bayou Sorrel Steering Committee and state/federal agencies. Eagle Environmental is
responsible for providing additional on-site O&M support.
5. Have there been any significant changes in site O&M requirements, maintenance schedules or sampling
routines since start-up or in the last five years? If so, do they affect the protectiveness or effectiveness of the
remedy? Please describe changes and impacts.
Yes, within the last five years there have been significant changes to the monitoring and
maintenance program. In September 2020, ERM submitted a proposal of long-term modifications
to the Bayou Sorrel monitoring program for PCY 31 and thereafter. The BSSC provided additional
information and formally requested to modify the groundwater, porewater, and stormwater
sampling programs at the Bayou Sorrel Site in a letter dated December 15, 2020. The EPA and
LDEQ provided a joint response to these recommendations on February 23, 2021, conditionally
approving modifications to the stormwater and porewater sampling programs; however, the
proposed revisions to the groundwater sampling network were not approved. The BSSC provided a
revised recommendation on March 31, 2021, per EPA and LDEQ request. The revised
recommendations were approved by the USEPA on April 27, 2021. The following modifications
have been incorporated into the program as of the PCY 31:
Discrete sampling of porewater chambers for indicator parameters of total dissolved solids,
total organic carbon, pH, and specific conductance is no longer required.
The porewater composite sample is analyzed for benzene only.
The frequency of stormwater sampling has been reduced to occur only during the Five Year
Review sampling event.
Sampling parameters for stormwater have been modified to be consistent with groundwater
parameters.
Semi-annual cap settlement surveys are no longer required. The cap surface will continue to be
inspected visually after mowing.
The frequency of site inspections has been reduced from weekly to quarterly.
The frequency of inspection and maintenance reporting has been reduced from semi-annually
to annually.
Additionally, the EPA requested that BSSC evaluate the condition of the deep groundwater
monitoring well located on the South Cap, DW-1, due to previous and unsuccessful sampling
attempts. The well was assessed, redeveloped, and sampled during the PCY 32 and will continue to
be monitored in accordance with the O&M Plan.
F-4
-------
Per LDEQ and USEPA approval, the upgradient wells (UW-1S, UW-2S, UW-1N, and UW-2N) were
plugged and abandoned on April 14, 2022, in accordance with the LDEQ and Louisiana
Department of Transportation and Development (LDOTD) Construction of Geotechnical Boreholes
and Groundwater Monitoring Systems Handbook.
These changes still maintain the protectiveness or effectiveness of the remedy.
6. Have there been unexpected O&M difficulties or costs at the Site since start-up or in the last five years? If so,
please provide details.
ERM has not encountered any unexpected O&M difficulties or costs at the Site in the last five years
related to groundwater monitoring activities.
7. Have there been opportunities to optimize O&M activities or sampling efforts? Please describe changes and
any resulting or desired cost savings or improved efficiencies.
As mentioned in the above question-response #5, a reduction in some monitoring and maintenance
requirements for the site was approved in 2021. Each of these changes result in a cost savings for
the overall sampling program. For example, reduction in parameters analyzed for porewater
monitoring reduces laboratory costs, and modifying the frequency of stormwater sampling to once
in 5 years reduces waste of unused bottle ware for years when stormwater was not present at the
site. The two upgradient wells on each cap were removed from periodic monitoring and plugged
and abandoned.
8. Do you have any comments, suggestions or recommendations regarding O&M activities and schedules at the
Site?
Based on our observations and the analytical results, we recommend continuing the currently
approved activities and schedule associated with the O&M activities at the Site.
9. Do you consent to have your name included along with your responses to this questionnaire in the FYR
report?
Yes

APPENDIX I - DETAILED SITE BACKGROUND INFORMATION
Physical Characteristics
As shown in Figure 1 of Appendix B, the Site is in Iberville Parish, Louisiana, approximately 20 miles southwest
of Baton Rouge (not shown on the figure), and about six miles northwest of the town of Bayou Sorrel. The
western border of the Site is bound by the Borrow River, a man-made drainage feature. This river was formed
during the construction of the Atchafalaya Basin Protection Levee, which is located approximately 100 yards to
the west. The north and east sides of the Site are bordered by the Upper Grand River and Pats Bayou,
respectively. Undeveloped swamp land is adjacent to the Site to the south. Access to the Site from the north is
along an unpaved levee road, 17 miles south of its intersection with Interstate 10 in Ramah, Louisiana. Access to
the Site from the south is along the same unpaved levee road and is approximately six miles north of the town of
Bayou Sorrel.
The Bayou Sorrel site is a "T" shaped, relatively flat parcel of land encompassing about 265 acres.
Approximately 50 of the 265 acres were used for waste disposal. The waste disposal areas consisted of four
landfills including a spent lime cell and a crushed drum cell, four covered liquid waste ponds, and one land farm.
A 50-acre lake and a one-acre pond, probably former borrow pits, are situated along the north border of the site.
Outside of the North and South area caps, dense brush and trees generally cover the site. The site (particularly the
south end) and surrounding areas can best be described as having marshy bayou-type environment and are prone
to periodic flooding and poor drainage.
Site Hydrogeology
On a regional scale, the first aquifer of significance is the Plaquemine aquifer, which is expected to be present at a
depth of about 100 to 125 feet beneath the ground surface at the Site. The total thickness of the Plaquemine
aquifer in this area is about 600 feet which, in the vicinity of the Site, consists of sand and gravel with a few, thin,
lenticular interbeds of silt and clay. The Plaquemine aquifer is confined, with the clays and silts of the overlying
top stratum (100 to 125 feet thick) comprising the upper confining unit.
The direction of ground water flow within the Plaquemine aquifer will vary on a seasonal basis as a result of
recharge from or discharge to the Mississippi River. This is due to the subsurface hydraulic connection between
the Mississippi River and the uppermost section of the Plaquemine aquifer in several areas where the river has
completely cut through the clay and silt deposits of the top stratum. Additional hydraulic connections between the
river and the aquifer are provided by the sandy point-bar deposits, which occur in the immediate vicinity of the
river.
Although ground water is present within the clays and silts of the top stratum, which immediately underlie the
Site, this shallow saturated zone is not considered a potential source for domestic use because of the low available
yield and poor regional ground water quality. The shallow saturated zone is not useable as a drinking water supply
due to its low transmissivity (the clay and silty deposits of the top stratum are typically in the range of 10-6 to 10-
8 cm/sec) and its inability to satisfy primary or secondary drinking water standards (analytical results have
consistently reported concentrations of chloride and sulfate in excess of these standards). Furthermore, there are
no known users or potential users of shallow ground water proximal to the Site.
Ground water in the shallow saturated zone is analyzed in accordance with the requirements of the Sampling and
Analysis (S&A) Plan and is the only relatively transmissive zone above the Plaquemine aquifer. Results of the
analyses of ground water from this zone, reported from the fourth quarter of Post-Construction Year (PCY) 2
through PCY 27, are summarized in Section IV. B. of this review and listed in Appendix E. Monitor well and
staff gauge locations used to define shallow ground water flow directions and gradients (within the shallow
saturated zone) across the North and South Area Caps are provided in Appendix B, Figures 2 and 3, respectively,
and shallow ground water flow directions proximal to the North and South Area Caps are depicted in Appendix B,
Figures 4 and 5, respectively. In general, shallow ground water flow direction in the vicinity of each cap is radial,
away from the caps.
1-1
-------
Due to the relatively large distance, approximately 13 miles, between the Site and the Mississippi River
(Appendix B, Figure 1), the effects of seasonal fluctuations in river stage on the shallow saturated zone are not
believed to be significant. This is due to the very low gradient in this area, which results in a very slow rate of
ground water movement through this zone. Constant fluctuations of the Mississippi River stage affect the water
table in the area of the Site, but only to a minor extent.
Surface gradients and the presence of a high-density polyethylene geomembrane liner on each cap significantly
reduce the potential for migration of storm water through the cap and promote sheet flow into perimeter drainage
swales designed to accommodate runoff from rainfall events. The swales discharge directly (via culverts installed
beneath the Site access roads) into the North and South Runoff Ponds illustrated on Figures 2 through 5 of
Appendix B.
Land and Resource Use
The site began operation as a hazardous waste landfill operated by the Environmental Purification Advancement
Cooperation (EPAC) in early 1977. Approximately 50 of the 265 acres were actually used for waste disposal.
Wastes were disposed in two sludge pits, four liquid waste ponds, two drum burial cells (one crushed drum/one
filled drum), and one landfarm area. The facility has been closed since the summer of 1978.
A Servitude Agreement and Declaration of Restriction for the site exists between the landowners and the BSSC
that severely restricts unauthorized access and use of the site and surrounding property. Currently, no persons
other than the BSSC representatives/contractors and authorized EPA and LDEQ officials are allowed access to the
Site without permission and the Site is not currently being utilized for any purposes other than activities
associated with ongoing, post-construction O&M monitoring. No future land uses (other than post-construction
O&M monitoring) are anticipated by the BSSC at this time. Site institutional controls are discussed more fully in
Section II.C of this review.
The following information is based on data from the 2010 United States Census. Approximately 33,390 people
live in Iberville Parish, Louisiana. Though no one lives on the Superfund site or directly adjacent to it. There are
approximately 30 seasonal fishing camps located across the Upper Grand River from the North Area Cap. The
Borrow River lies between the site and the Atchafalaya River Basin levee. The population of the City of
Plaquemine, which lies 13 miles to the northeast of the site, is 7,119. The town of Bayou Sorrel is six miles south
of the site and due north of the Bayou Sorrel waterway. Approximately 1,000 residents live along the bayou and
within the town of Bayou Sorrel.
Although ground water is present within the clays and silts of the top stratum, which immediately underlies the
site, this shallow saturated zone is not considered a potential source for domestic use because of the low available
yield and poor regional ground water quality. The shallow saturated zone is not useable as a drinking water supply
due to its low transmissivity (the clay and silty deposits of the top stratum are typically in the range of 10-6 to 10-
8 cm/sec) and its inability to satisfy primary or secondary drinking water standards (analytical results have
consistently reported concentrations of chloride and sulfate in excess of these standards). Furthermore, there are
no known users or potential users of shallow ground water proximal to the site.
History of Contamination
The Bayou Sorrel Site began operation in early 1977. It was operated by Environmental Purification
Advancement Corporation (EPAC). A sister firm, Clean Land Air Water (CLAW, Inc.) operated an injection
well approximately six miles south of the site, in the town of Bayou Sorrel.
1-2
-------
EPAC operations included land farming, open liquid impoundments, drum burial, and landfilling of "chemically
fixated" wastes. The LDEQ officials report that all of these except the open pond were permitted by the State.
The fixation process was unknown but may have included lime, cement, and native soils. EPAC was supposedly a
separate operation from CLAW. However, court testimony by former employees suggests that wastes were
diverted from the injection well to the EPAC site when process problems at the well caused a bottleneck.
Therefore, both injection-well waste records and EPAC records were included in summarizing wastes possibly
present at the site.
According to records retained by the Potentially Responsible Parties (PRP) Group, the majority of wastes
disposed of at the Site fell into three categories:
Process wastes from chemical manufacture.
Sulfide-containing wastes (scrubber blowdown and spent caustic) from hydrocarbon processing and
exploration activities; and
Spent wash solutions from boiler-cleaning and equipment-cleaning contractors.
In the summer of 1978, State and Federal regulatory officials inspected the site following an incident occurring at
the site. The investigation revealed the presence of large open, unpermitted ponds containing unknown materials.
As a result of the governmental investigation, the 18th Judicial District Court ordered the closure of the site to
eliminate all health hazards.
Initial Response
The Site was operated by EPAC until the summer of 1978 when it implemented a court-ordered closure of the
Site from September 1978 through June 1979. During this closure, conducted under the oversight of the State of
Louisiana, the contents of Ponds 1, 2, and 3 (South Area Cap) were reportedly pumped to Pond 4 (North Area
Cap) where solids were concentrated by enhancing evaporation and landfarming pond supernatant. These ponds
were then filled and covered with soil. Pond 4 was closed by the use of enhanced evaporation within the pond.
The remaining Pond 4 contents were then covered with native soils. Sampling activities were performed
concurrent with the closure which resulted in the detection in onsite soils of various organic compounds, heavy
metals, phenols, oil and grease, asbestos, cyanide, sulfide, and other inorganics.
During the transfer of material to Pond 4 from Ponds 1-3, there may have been some spill-over of material to the
periphery of Pond 4. Closure activities were completed in the spring of 1979, and later that year EPA placed the
site on inactive status. The quantity of wastes remaining on site was estimated to be 1 million cubic feet (36,400
cubic yards) (Remedial Investigation (RI) report). After closure, the State received complaints about odor and
surface contamination in the south of the site. The State contracted Resource Technology, Inc. in 1981 for a
preliminary site investigation, and a further Investigation by Woodward-Clyde Consultants was completed in
1982. These studies included installation of a total of 12 groundwater monitoring wells, although only three of
these were sampled. Definitive pesticide surface contamination evidence was collected, but ground water data
were inconclusive. Based on the aforementioned information, the site was placed on the NPL on December 20,
1982.
Results from the RI sampling indicated that surface and subsurface soil contamination, including herbicides, other
organic compounds, and some cadmium compounds, was found in several areas of the site. Most of these areas
are located in the former sludge pits and disposal ponds located in two distinct areas of the site: the sludge pit and
Ponds 1, 2, and 3 in the South Area Cap and Pond 4 and the crushed drum cell in the North Area Cap. There was
estimated to be 1,000,000 cubic feet of contaminated soils in these areas that were deemed to present a current or
potential risk if left unmanaged. Some actual waste material (able to liberate hydrogen sulfide) was found in the
North Area Cap as well. Unless the soil cover that was placed in the pits in the earlier closure activities was
penetrated, no air emissions were detected anywhere during the investigation.

This report shows the values for environmental and demographic indicators and EJSCREEN indexes. It shows environmental and demographic raw data (e.g., the
estimated concentration of ozone in the air), and also shows what percentile each raw data value represents. These percentiles provide perspective on how the
selected block group or buffer area compares to the entire state, EPA region, or nation. For example, if a given location is at the 95th percentile nationwide, this
means that only 5 percent of the US population has a higher block group value than the average person in the location being analyzed. The years for which the
data are available, and the methods used, vary across these indicators. Important caveats and uncertainties apply to this screening-level information, so it is
essential to understand the limitations on appropriate interpretations and applications of these indicators. Please see EJSCREEN documentation for discussion of
these issues before using reports.

* Diesel particular matter, air toxics cancer risk, and air toxics respiratory hazard index are from the EPA's Air Toxics Data Update, which is the Agency's
ongoing, comprehensive evaluation of air toxics in the United States. This effort aims to prioritize air toxics, emission sources, and locations of interest for
further study. It is important to remember that the air toxics data presented here provide broad estimates of health risks over geographic areas of the country,
not definitive risks to specific individuals or locations. Cancer risks and hazard indices from the Air Toxics Data Update are reported to one significant figure and
any additional significant figures here are due to rounding. More information on the Air Toxics Data Update can be found at: https://www.epa.gov/haps/air-
toxics-data-update.

EJScreen is a screening tool for pre-decisional use only. It can help identify areas that may warrant additional consideration, analysis, or outreach. It does not
provide a basis for decision-making, but it may help identify potential areas of EJ concern. Users should keep in mind that screening tools are subject to substantial
uncertainty in their demographic and environmental data, particularly when looking at small geographic areas. Important caveats and uncertainties apply to this
screening-level information, so it is essential to understand the limitations on appropriate interpretations and applications of these indicators. Please see
EJScreen documentation for discussion of these issues before using reports. This screening tool does not provide data on every environmental impact and
demographic factor that may be relevant to a particular location. EJScreen outputs should be supplemented with additional information and local knowledge
before taking any action to address potential EJ concerns.
