I. INTRODUCTION
The purpose of a Five-Year Review (FYR) is to evaluate the implementation and performance of a
remedy in order 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 United States 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 sixth FYR for the Chem Central Superfund Site. The triggering action for this statutory review
is the completion date of the previous FYR. The FYR has been 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 consists of one site-wide operable unit (OU) which will be addressed in this FYR. The site-wide
OU addresses groundwater contamination and related soil contamination.
The Chem Central Superfund Site (Site) FYR was led by Alyssa Graveline, EPA's Remedial Project
Manager (RPM) for the Site. Participants included EPA Community Involvement Coordinator, Diane
Russell; State agency representatives, Shelby Bahaw and Nicholas Shorkey of the Michigan
Department of Environment, Great Lakes, and Energy (EGLE); and Alexander Jimenez, Project
Engineers with the United States Army Corps of Engineers. The potentially responsible party (PRP),
Univar USA, Inc., was notified of the initiation of the FYR. The review began on 11/17/2023.
Site Background
The Chem Central Site is a 2-acre parcel of land located at 2940 Stafford Avenue in Wyoming,
Michigan. The City of Wyoming is a southern suburb of Grand Rapids which is located in west-central
Michigan, approximately 25 miles east of Lake Michigan in Kent County (Figure Bl, Appendix B). The
Site encompasses both a square shaped piece of property formerly owned by the Chem Central
Corporation (now owned by Univar USA, Inc.), which is the location of the operating plant, and a
rectangular piece of land owned by Consumers Power (Figure B2, Appendix B). The Chem Central
property is relatively flat while the Consumer Power property consists of undulating terrain. Cole Drain,
a small urban creek flowing in a northerly direction, is located along the Site's western boundary.
Cole Drain receives most of the surface runoff from the Site and recharge to groundwater particularly
during storm water events (WW Engineering & Science, Inc., 1990). Cole Drain enters Plaster Creek at a
confluence approximately 2,500 feet north of the Site. Plaster Creek enters the Grand River
approximately 2.5 miles northwest of the Site. The Grand River Flows to the west for approximately 30
miles and enters Lake Michigan at Grand Haven.
The Chem Central plant was constructed in 1957 and received bulk chemicals by truck or railroad
tanker and stored these chemicals in on-site tanks before redistribution to various industries. The
5
-------
property was undeveloped prior to construction of the plant. Between 1957 and 1962, hazardous
substances entered the ground as a result of faulty construction of a T-arm pipe used to transfer liquid
products from bulk storage tanks to small delivery trucks. Additional hazardous substances may have
entered the ground through accidental spills.
In July 1977, a routine biological survey of Plaster Creek resulted in the discovery of a contaminated
ditch draining into Cole Drain. This ditch, identified as the 28th Street ditch, was located immediately
north of 28th Street and north of the Chem Central property. The 28th Street ditch contained oils and
concentrations of polychlorinated biphenyls (PCBs) and metals in the low parts per million ranges. In
December 1982 the property was proposed for inclusion on the National Priorities List (NPL) and
finalized on the list in 1983.
The currently operating plant consists of one structure with two loading docks and a rail spur on the
west side of the Site. The property is fenced, and access is restricted. The adjacent property to the east
is a Consumer Power transformer yard. The land adjacent to the west is a right of way for the Conrail
Railroad Company's single line track. Adjacent to the rail line is U.S. Route 131, a four-lane limited-
access highway. The adjacent properties north and south of the Site are privately owned and are
occupied by commercial and light industrial facilities. The Site is situated in a mixed residential and
commercial section of the City of Wyoming that includes small industrial facilities. Plans for Site use
now and moving forward are for it to continue to be used for commercial storage and distribution of
dry goods. The nearest residences are located approximately 500 feet west of the property boundary
and two hotels are located within 800 feet of the Site. There are no known private residential wells
near the site as the area is connected to municipal water.

II. RESPONSE ACTION SUMMARY
Basis for Taking Action
In June 1987, pursuant to an administrative order by consent (AOC) with EPA (Docket No. V-W-87-C-
017), Chem Central conducted a Remedial Investigation (Rl) and Feasibility Study (FS) (WES, 1990;
1991). The Rl was conducted by Chem Central between August 1988 and January 1989, and the FS was
conducted from 1989 through 1991 (WES, 1990; 1991).
The Rl groundwater investigation found the site groundwater to contain approximately thirty-five
different organic compounds. Groundwater contamination was detected in a plume extending north of
the property down-gradient to Cole Drain near Mart Street. At the time of the Rl, contaminated
groundwater was not flowing into Cole Drain based on results of surface water samples collected from
Cole Drain. No groundwater contamination was detected west of Cole Drain, down-gradient of the Site
(WES, 1990).
Potential exposure pathways for humans that were evaluated in the Rl's baseline risk assessment
included: inhalation of air emissions from the stripping tower, dermal contact with water in Cole Drain,
consumption offish, dermal contact with soil and sediments, ingestion of soil, sediments, or
groundwater. Exposure pathways for ecological receptors that were evaluated were from ingestion
and dermal contact in Cole Drain (WES, 1990). Human receptors potentially exposed to the
contamination at the Site include persons working at the plant, children who may play in Cole Drain or
in areas where contaminants have been detected in soils, employees of nearby businesses, and
residents of nearby areas. Individual ecological receptors that were identified are noted below.
• Plants: small to medium sized trees (Siberian elm, box elder, cottonwood), shrubs, other weedy
specie, algae, and watercress.
• Animals: fish, amphibians, reptiles, mammals, birds.
• Threatened species: peregrine falcon, coopers hawk, red shouldered hawk, marsh hawk,
osprey, black rat snake, eastern box turtle, least shrew.
The baseline risk assessment concluded that there was unacceptable risk to human health for direct
contact and ingestion of surface soils on the Chem Central property, and for ingestion of groundwater
from the plume area beneath the Site. At the time, the on-Site soil exposure pathway was considered
7
-------
not to be complete as the soil was covered with pavement and loose gravel. Unacceptable risks to the
environment were identified for exposure to soils on and off-Site and for the water in Cole Drain.
Contaminants of Concern (COCs) which were listed in the Record of Decision (ROD) (EPA, 1991) as
having remedial goals are listed in Table 1 and Table 2 in the Response Actions section, by media type,
with their chosen Site goals (Clean-up Goal, CUG).
Response Actions
In 1977, a routine State biological survey of Plaster Creek identified oils with organic compounds
including PCBs and metals within the 28th Street ditch that discharged into Cole Drain. In 1977, the
State attempted to stop the flow of oil by damming the ditch. In 1978, the EPA excavated sludge from
the ditch and removed sludge using 12 55-gallon drums for off-Site disposal. Oils, groundwater, and
various contaminants continued to enter the 28th Street ditch, and the State unsuccessfully attempted
to filter oil out of the water. Between 1978 and 1986, the State and the EPA focused their efforts on
finding and eliminating the source of the ditch contamination through extensive investigations of
area soil, groundwater, and surface water. Results indicated that groundwater and soil both
surrounding and north of the Chem Central plant were contaminated with volatile and semi-volatile
organic compounds.
In 1980, the State of Michigan Department Natural Resources (MDNR) filed a suit in the Kent County
Circuit Court in an effort to get the Chem Central Corporation to clean up the contamination. In 1984
the court ordered the Chem Central Corporation to undertake clean-up activities which included (1)
defining the extent of contamination, (2) designing, constructing, and operating a groundwater
collection and treatment system until court-ordered clean-up standards were met, and (3) cleaning up
contaminated soils in the ditch. Consequently, between 1984 and 1985, three groundwater extraction
wells, an interceptor trench, and a treatment system using an air stripper were installed. From
November to December 1985, the ditch was dewatered and 1,560 cubic yards of material (estimated
backfill volume) was removed from the trench. Of the excavated material, 80 cubic yards were
disposed of as toxic waste due to PCB concentrations greater than 50 milligrams per kilogram (mg/kg).
The remaining material contained less than 50 mg/kg of total PCBs. Post-remedial sampling was
performed confirming residual soil in the trench contained less than 1.2 mg/kg PCBs (WES, 1990). The
underdrain, currently a component of the groundwater extraction system for the Site, was installed in
1986 to prevent contaminated groundwater from entering Cole Drain.
Based on the findings of the Rl and Baseline Risk Assessment, a FS was conducted to identify and
evaluate different clean-up options. The FS was completed on June 21, 1991. The EPA issued the
Record of Decision (ROD) on September 30, 1991. The ROD selected a remedy to address impacted on-
Site soil, off-Site soil surrounding and north of the plant, and the groundwater contamination plume
emanating from the plant and spreading 1,800 feet northward. The ROD excluded soils beneath the
Chem Central building and paved areas on the Chem Central property. The exclusion noted that these
soils were not ruled out as potential source areas for further groundwater contamination and indicated
that these areas should be investigated further at a later date (EPA, 1991).
8
-------
The primary COCs affecting the soil and groundwater are volatile organic compounds (VOCs) including
tetrachloroethene (PCE), trichloroethene (TCE), toluene; and other organics including polycyclic
aromatic hydrocarbons (PAHs) and PCBs. The ROD included the following remedial action objectives
(RAOs) and remedy components:
• RAOs
o Prevent current or future exposure to both contaminated soil on and off the Chem
Central property;
o Prevent exposure to contaminated groundwater in the site area;
o Prevent further migration of contaminants in soil down into groundwater; and
o Prevent discharge of contaminated groundwater into Cole Drain.
• Remedy components selected in the ROD
o Continue operation and maintenance (O&M) of the current groundwater collection and
treatment system;
o Install, operate and maintain an expansion of the current off-property groundwater
collection system, either by extending the interceptor trench or installing additional
extraction wells;
o Install, operate and maintain an extraction well at the deep location of contaminated
groundwater identified in the Rl;
o Collect oil in the extraction wells and dispose of the oil at the off-Site facility in
accordance with applicable federal and state regulations;
o Install, operate and maintain a soil vapor extraction (SVE) system for soils on property as
well as two off-property locations just north of the Chem Central property;
o Institutional controls (ICs) such as deed restrictions to prohibit the installation of water
wells in the site area and any future development that might disturb contaminated soils
will be sought; and
o Implement a groundwater monitoring program capable of demonstrating the
effectiveness of the groundwater capture system.

Status of Implementation
On March 31, 1992, the EPA issued a final Unilateral Administrative Order (UAO) to the Chem
10
-------
Central Corporation. The UAO required Chem Central Corporation to perform a remedial design for the
remedy described in the ROD and to implement the design by performing the remedial action. The
effective date of the UAO was April 7, 1992 (EPA, 1992). The following sections discuss the
implementation of the remedy components.
Soil Vapor Extraction System
The original SVE system was designed and constructed at the Site in accordance with the ROD for
treatment of soils between 1994 and 1995. Four extraction wells were installed immediately to the
west and north of the Chem Central property to remediate on-property soils and two extraction wells
were installed north of the Site on the Consumers Power property to treat off-property soils. Three
passive vent wells were also present. The SVE system fed into the groundwater air stripper (see
Groundwater Extraction/Treatment System, below) for treatment of the VOCs. To optimize the air flow
through the soils on-property and to protect the extraction wells from damage due to truck traffic, the
on-property soils were paved over with concrete. The SVE system was first operated intermittently in
August 1995 and January 1996. Full time operation began in March 1996.
A soil gas survey was conducted in 2009 in order to evaluate whether there was residual source
material that might not be treated by the existing SVE system such that repairs or improvement to
the system were warranted. Based on the results, the SVE system was upgraded in 2011 to handle
increased air flow with larger regenerative vacuum blower. Three new vertical SVE wells and one
horizontal SVE well were installed. The new regenerative blower specifications included flow of up to
400 cubic feet per minute at approximately 50-inches of water column.
The SVE system layout is shown on Figure B4 (Appendix B) in conjunction with details of the oxygen
sparge system (see Bio-enhancement section, below) along with the treatment equipment layout. The
use of oxygen sparge points were discontinued in late 2016 after they were shown to no longer be
enhancing treatment. The current operating SVE system consists of five SVE laterals (A through E), six
vertical SVE wells (SVE-1 through SVE-6), a knockout tank, and a 15-horsepower regenerative blower.
Since September 2020 All SVE laterals (A-E) and extraction wells have been operating.
Groundwater Extraction/Treatment System
The groundwater treatment system began operation in September 1985. The stripping tower removed
contaminants from the groundwater to air. The contaminated air was passed through a steam-
regenerative carbon vapor adsorption (CVA) system having about 90% efficiency in the removal of total
contaminants from the air. Waste solvents collected in the CVA system are drummed and disposed of
properly. Treated water discharges from the stripping tower to the City of Wyoming's Clean Water
Plant. Well locations are shown on Figure B2 and the treatment system layout is shown on Figure B4
(Appendix B).
Contaminated groundwater was initially pumped from three extraction wells (PW-1, PW-2 and PW3)
from the plume north of Chem Central (now named Univar USA, Inc.) to the stripping tower for
treatment through underground transmission piping. The extraction wells were capable of producing
an approximate combined flow rate of 90 gallons per minute (gpm). The water flows through an
11
-------
oil/water separator (OWS) before entering the stripping tower. The OWS removes floating oil from the
groundwater. The small amount of oil is removed from the Site, drummed, and disposed off-Site
Flow from another extraction well, SCH-2, also discharged to the stripping tower. SCH-2 was modified
in order to extract and capture impacted groundwater from a water-bearing gravel lens. The flow from
SCH-2 was very small compared to the flow from the other wells. The extraction well SCH-2 was
screened within the deep aquifer. Operation of SCH-2 as an extraction well began in April 1996 and
stopped in 2022 to prevent further contamination to the deeper aquifer (see Groundwater Extraction
and Treatment section in the Data Review). The SCH-2 well was replaced by the PW-5 well in 2022
(SCH-2 will be officially abandoned in the fall of 2024).
An underdrain system, referred to as the North Underdrain or PW-4, was installed next to and roughly
parallel to Cole Drain in November and December 1986. The underdrain began operating in April 1987.
The underdrain collected impacted groundwater and prevented it from entering Cole Drain. The
underdrain consists of about 1,000 feet of four-inch perforated pipe placed in a gravel filled trench
extending from 28th Street northward. Collected water flowed north to a pumping station from which
it was pumped back to the air stripping tower for treatment and discharge to the city. PW-4 was
damaged and has not been operational since 2014, see the Data Review section for further discussion.
Bio-enhancement
A bio-enhancement plan was submitted in 2009 and executed in 2011 including the installation of
an aerobic remediation system and increased vadose zone vapor extraction (IES, 2012). Anaerobic
enhancement was proposed for the treatment of chlorinated VOCs. The system included 50 oxygen
sparge wells and SVE laterals within the well connection trench (see discussion of the SVE system,
above). The system began operation in December 2011. Of the 50 oxygen sparge well, 10 deep sparge
wells were operated through 2013 (EPA, 2014). The remaining 40 shallow oxygen sparge wells were
operated through late 2016 when the sparge compressor faulted. The system was not rehabilitated
based on the Site data that indicated that non-chlorinated VOC contaminant mass was largely outside
the area of influence of the oxygen sparge system (EPA, 2019).
Trench Extension
The 1991 ROD called for an expansion of the current off-property groundwater collection system (the
north underdrain interceptor trench) on the north end to capture the contaminant plume before it
enters Cole Drain. The PRPs completed the design of the extension in 1994; however, additional
evaluation of the hydrogeology was deemed necessary prior to installation. An investigation was
completed from August to November 1997. Based on the results of the investigation, the extension
was not constructed (EPA, 2009). Instead, the Site begin its Groundwater Surface Water Interface
monitoring program (GSI MP, discussed below) to monitor potential flow to Cole Drain. As to date, this
replacement to the requirement for extension has not been properly documented in a ROD
modification. As a future ROD amendment is considered, this component should also be included.
Monitoring Program
The PRPs implemented the GSI MP starting in June 1999. The program was developed to provide a
comprehensive monitoring of the groundwater plume, and also to ensure that downgradient
groundwater would not impact Cole Drain above GSI criteria (EPA, 1999). Data from the program has
12
-------
been used to establish a baseline of data for the plume. Currently, groundwater north (to Plaster
Creek) of the Chem Central (Univar USA, Inc.) property is not used for drinking water purposes. Data is
reviewed in Section IV of this report.
Flow rates and VOC concentrations of the vapor stream are monitored on a quarterly basis. Treated
effluent from the air stripping system and the discharge from the air/vapor collection system are
monitored for compliance with applicable regulations.
Institutional Controls
ICs in the form of deed restrictions are required by the ROD to restrict property use, maintain the
integrity of the remedy, and ensure the long-term protectiveness for areas which do not allow for
UU/UE. A summary of the implemented and planned ICs for the Site is listed in Table 3 and is further
discussed below. A map which depicts the current conditions of the Site and areas which do not allow
for UU/UE is included in Appendix D.

Status of Access Restrictions and ICs: ICs were implemented through deed restrictions for parcels
2, 3, and 6. Deed restrictions were recorded in Liber 3118, Page 101 through 109. A copy of these
records are included in Appendix D. The deed restrictions for Parcel 6 (the Chem Central Property)
were executed and acknowledged on October 7, 1992. The deed restrictions for Parcels 2 and 3
were executed and acknowledged on December 11, 1992. The ICs for the remaining parcels have
been drafted by Univar USA, Inc. and are under review by EGLE.
Current Compliance: An IC plan for the Site was approved in 2011 (IES, 2011; EPA, 2011). The plan
included review of ICs at a minimum of every five years, and inspections for IC compliance annually.
There have not been any recent noted compliance issues on the three parcels that currently have ICs in
place (parcels 2, 3, and 6). A 2019 incident underscores the importance of recording the additional ICs
without further delay. A building addition on the Gilmore property (parcel 4), on the west side of the
Cole Drain destroyed monitoring wells MW-42A, MW-42B, and MW-42C. Only the MW-42D nested set
13
-------
is still intact. The PRP, state, and federal agencies were not notified during the planning of this building
addition. No other known activities have been observed or documented on the parcels currently
pending the application of ICs that could pose a risk to receptors.
IC Follow up Actions Needed: For the parcels that have not yet implemented ICs: Upon the completion
of EGLE's review and their concurrence with ICs, submit finalized environmental covenants to the
respective property owners for review, signature, and recording. Perform routine IC inspections and
document inclusion of upcoming newly added IC inspections in subsequent reviews. It is anticipated by
EPA that implementation of ICs can be achieved by the end of 2025.
Long Term Stewardship: Compliance with ICs is necessary to ensure the protectiveness of the
remedy. The IC Plan that was approved November 30, 2011 includes procedures to ensure long term IC
stewardship such as regular inspection of ICs at the Site and annual certification to the EPA that ICs are
in place and effective (EPA, 2011). As part of the IC Plan, regular reviews of the monitoring reports are
being conducted to ensure IC mechanisms are functioning properly.
Systems Operations/Operation & Maintenance
Remediation System Operations
From 2014-2019 a significant number of optimization activities were implemented at the Site to
improve remedial performance. In the past five years there have been additional changes based off the
optimization study results. Summaries of the recent activities and changes are summarized per remedy
function below. O&M activities are reported in the Site's monthly report submittals; details of the
O&M activities are discussed in the Remediation System Maintenance subsection below.
Groundwater Extraction and Treatment
As of the 4th quarter of 2023, the operational components of the groundwater extraction and
treatment system have been isolated to four extraction wells identified as PW-1R, PW2R, PW-3RR, and
PW-5. Extraction wells PW-1R, PW-2R, and PW-3RR are shallow aquifer wells, installed in November
2016 as replacement extraction wells (of PW1, 2, and 3) to optimize system operations. The PW-5 well
is a deeper aquifer well installed in 2022 to replaces the SCH-2 well, discussed further below.
Groundwater is extracted from these wells, treated via an air stripper, and discharged to the City of
Wyoming Publicly Owned Treatment Works (POTW). The air stripper was replaced in November 2018.
Extraction well SCH-2 was located in the deep aquifer (about 45ft bgs) adjacent to the main Chem
Central building (also identified as Univar Building 1). Groundwater investigations conducted in 2020
observed Site COCs in the deeper aquifer, see Deep Aquifer Groundwater subsection in the Data
Review section for more discussion. The SCH-2 well was proposed for closure to prevent a future
conduit for contaminate to migrate to the below aquifer. The EPA approved the SCH-2 for closure and
replacement, and the well was replaced (by well PW-5) in 2022; official abandonment is planned for
this fall. Extraction well PW-4, connected to the underdrain system located north of 28th Street, has
not been operational since March 31, 2016.
Data for the operation of the groundwater treatment system including the amount of water treated
and the percentage of time this system was operational for each quarter over the last five years is
present in Appendix F; F2. Quarterly reports show the system has operated between 85-100% of the
time during the last five years.
14
-------
Soil Vapor Extraction
From 2017 to fall of 2020 only SVE laterals C and D were operational, focusing on vacuum influence
under the main building (Univar Building 1). At the request of EGLE, all horizontal and vertical wells
were turned on in the fall of 2020 to assess changes in influent mass recovery; since then all SVE
components have been operating. The operating SVE system consists of five SVE laterals (A through E)
and six vertical SVE wells (SVE-1 through SVE-6). The PRP team is developing a workplan for SVE pulse
testing, for further optimization, or to evaluate a potential shutdown. The EPA's expectation is that SVE
testing will begin in the spring of 2025. See more discussion on this in the Data Review section.
Details on the maintenance of these systems are provided below (Arcadis, 2024c).
Remediation System Maintenance
Routine system O&M activities are performed twice a month.
The groundwater extraction system and SVE system have both experienced short periods of down time
in the last five years. A contingency plan addressing how long the systems can be down without
adverse effects and what interim actions should be taken during system down time has not yet been
developed. The systems have experienced short periods of downtime for mostly routine O&M
activities as well as operational changes during the last five years. As discussed later, the Site's
Conceptual Site Model (CSM) requires an update; once this is completed, a contingency plan may need
to be developed with the finalized future remedy.
Groundwater monitoring is conducted quarterly in accordance with the Plume Dynamics (PD)/ GSI MP
and is reported in the Site quarterly reports (Arcadis, 2024a). The program includes PD monitoring, GSI
monitoring, and the court-ordered monitoring program, further described below in Data Review.
Additionally, a Progress Monitoring Program (PMP) has been in place with the intention of tracking the
progress of VOC remediation within and downgradient of the aerobic enhancement remediation
system. Active remediation ceased in December 2016 when the oxygen sparge portion of the system
was shut down due to complications from operating the oxygen sparge system upgradient of the
groundwater recovery system. The PMP includes quarterly monitoring of MP-1, MP-2, MP-3R, MP-6,
MP-7, MW-16A, MW-16B for VOCs, dissolved oxygen, pH, conductivity, oxygen-reduction potential,
total iron, and total manganese. The extraction wells were also evaluated as part of this program. The
PMP is tracked and recorded as a part of the Sites quarterly reports (Arcadis, 2024a).

OTHER FINDINGS from the 2019 FYR
The EPA identified the following recommendations that do not affect the protectiveness of the remedy
in the last FYR. A status update is provided below.
*Other Finding #1: As discussed in the Data Review section, a separate plume of PCE contamination
has been identified in groundwater east of impacts associated with the Chem Central Site. Portions of
this plume may also comingle with the Chem Central groundwater plume. This plume should be
delineated and distinguished from the Chem Central plume to aid in administration of investigative and
remedial actions.
Status 1: The Groundwater Hydraulic Investigation workplan includes goals to delineate the secondary
plume along the Western edge in relation to the Site and therefore determine its potential impacts to
20
-------
the Site (Appendix L; LI). The hydraulic workplan has been approved by the EPA and is expected to be
implemented in fall of 2024 (EPA, 2024b).
*Other Finding #2: A remedial action contingency plan should be developed for when the remedial
systems experience periods of down time. This plan should include how groundwater containment will
be maintained and what actions need to be taken to protect downgradient receptors.
Status 2: This still needs to be completed. Currently the EPA recommends that the contingency plan be
incorporated into the O&M Plan, as a new section or attachment.
*Other Finding #3\ Aside from maintenance activities, the SVE system appears to be operated on a
continuous basis. In order to improve system efficiency, and to reduce effects from preferential
pathways, pulse operation of the system should be evaluated. In addition, the collection and
evaluation of additional system data would aid in the optimization of the system operation including
flow and effluent data for each of the extraction wells.
Status 3: A SVE pulse test workplan is under review by the EPA. The EPA and the PRPs are in agreement
the SVE should be optimized to aide remedy performance or be considered for potential shutdown.
The Site team is looking to begin with a short-term pulsing test that will last 3-4 months and then re-
evaluate the system using this and the new soil data.
*Other Finding #4: The MW-42 well cluster was impacted by building construction. These wells, if
damaged, can act as conduits to the aquifer. The wells should be located and properly abandoned.
Current characterization data should be evaluated to assess replacing these monitoring points in
another representative location.
Status 4: The impacted wells are not able to be properly abandoned due to the referenced building
expansion. Although the EPA recommends the unaffected MW-42D remain as a sentinel well to
monitor the northwest corner of the contaminated groundwater.
*Other Finding #5: Iron-stained discharge has been noted on the east bank of Cole Drain as well as
high iron levels in Site groundwater samples. To better evaluate the discharge and its relation to the
discharge of the plume in this area, GSI sentinel and compliance wells and PZ-6B, PZ-7A, and PZ-7B
should be sampled for total metals including iron.
Status 5: Site monitoring reports now include sampling for iron and magnesium close to the main
Univar building. Sampling for metals is not occurring downgradient at wells referenced above; this is
still an ongoing Other Finding.
*Other Finding #6\ Water level contours indicate that Cole Drain is gaining in reach, meaning
groundwater is likely discharging to the creek. Adding or re-establishing staff gauges in Cole Drain
would provide useful data in understanding the discharge of groundwater to the drain.
Status 6: The soil investigation workplan includes installing two staff gauges into the Cole Drain creek.
It is anticipated work will begin fall of 2024 (2024; Appendix L; L2) (EPA, 2024b).
21
-------
*Other Finding #7: Quarterly PD/GSI Monitoring Reports should be updated to compare analytical
results to the ARAR-based cleanup levels as shown 'in' Appendix F (in the 2019 FYR).
Status 7: Monitoring reports have been updated so that the following criteria is included: GSI criteria,
non-residential drinking water criteria, residential drinking water criteria.
*Other Finding #8: Results in the quarterly vapor intrusion investigation reports should be presented in
a table displaying only detectable results. Presenting all results obscures detected concentrations of
PCE and vinyl chloride with concentrations below the screening level.
Status 8: The PRP made the results in the vapor intrusion reports filterable so that they can be viewed
cumulatively or selectively as described above.
IV. FIVE-YEAR REVIEW PROCESS
Community Notification. Involvement & Site Interviews
A public notice was made available by available by electronic publication on the EPA's public website,
as well as a newspaper ad (Grand Rapids Press), which was advertised on December 21, 2023 (see
Appendix E). The notice stated that there was a FYR and invited the public to submit any comments to
the EPA. The results of the review and the report will be made available at the Site information
repository for the Wyoming Public Library Superfund Site information repository located at the Kent
District Library- Wyoming Branch, 3350 Michael Ave SW, Wyoming, Ml 49509; and at:
www.epa.gov/superfund/chem-central .
No inquiries or comments were received from the community. No community interviews were
conducted.
Data Review
Groundwater
Neighboring Plume
The 2017 Groundwater Investigation of a secondary plume and analysis, including molar ratio, was
completed to determine if the presence of PCE downgradient to the north and northeast of the Site is
related to the neighboring Integral Grinding Abrasives Inc. (IGA) Property (Arcadis, 2017). Results
supported that the IGA plume was the source of downgradient PCE, but more work is needed to
delineate and distinguish the plumes, as well as determine if and where this second plume may be
interacting with the Site's plume. The Hydraulic Investigation workplan was approved by the EPA and
work is expected to begin in fall 2024 (EPA, 2024b); therefore, no additional data was available for
review during this FYR. The teams expect to be able to start this next secondary plume investigation by
fall of 2024 (Appendix L; LI). Understanding the potential Site impacts of the IGA plume will be
important for scoping future expectations for Site conditions and needs.

Groundwater Monitoring
During the last five years, 20 rounds of groundwater sampling were completed and reported in
quarterly PD/GSI MP reports (ARCADIS 2019a-c, 2020a-d, 2021a-d, 2022a-d, 2023a-d, 2024). Appendix
G includes recent and historic groundwater data. A summary of the last five years for this data is
provided below in the Groundwater Quality section.
Groundwater Flow
Depth to groundwater measurements have been collected during the quarterly groundwater sampling
events. Groundwater contour maps are prepared based on the depth to groundwater measurements.
The most recent groundwater elevation contours are displayed in Appendix B; B3. The direction of
groundwater flow at the Site is to the north (Arcadis 2023a-d, 2024). Consistent with the last FYR,
water levels indicate that groundwater may be discharging to Cole Drain. Discussion on Cole Drain is
below under the Surface Water subsection.
Groundwater Quality
Quarterly PD/GSI MP reports compare analytical results from the PD monitoring, GSI monitoring,
court-ordered monitoring, and PMP monitoring GSI criteria and nonresidential and residential drinking
water criteria within the Site quarterly reports. Sampling results from 2019-2023 are shown in
Appendix G.
Applicable or relevant and appropriate requirements (ARARs)(e.g., clean-up levels/goals) are detailed
in the ROD. The 2019 FYR included an ARAR evaluation which assessed whether the clean-up goals
(CUGs) detailed in the ROD were still valid (EPA, 2019). The ARAR assessment found that updated
Michigan Part 201 clean-up criteria for the protection of surface water (GSI criteria) is more stringent
than the ROD groundwater clean-up levels for ethylbenzene, 2-methylphenol, naphthalene, 1,1,1-
trichloroethane, and xylene, shown in Table 6 below. The Site quarterly reports are now comparing
analytical results for the COCs detected in Site monitoring wells to these updated GSI criteria.

GSI sentinel wells (sampled quarterly) within the Chem Central plume area include MW-29A, MW-40R,
and MW-60. During the last five years, these sentinel wells had one GSI exceedance. The GSI
exceedance was at the M W40R well in 2020 when 2 |ag/L of vinyl chloride was observed. For the M W-
29A well the last time a GSI exceedance occurred was in 2001, and the last exceedance at MW60 was
23
-------
in 2014 (both these wells last exceedances were also vinyl chloride). (ARCADIS 2024a, 2024b; EPA,
2004).
Wells MW-37 and MW-65 are used as additional sentinel wells and are located within the
PCE/daughter product plume. PCE has consistently exceeded the cleanup goal (0.7 |ag/L) in these
monitoring wells. Concentrations of PCE in these wells have ranged between 5.3 |ag/L and 11.8 |ag/L
over the last five years (Arcadis, 2024), see Table 7 below. No other COC clean-up goal exceedances
were noted in these wells. Mann Kendall analysis from 2014- 2023 at MW-37 well show no significant
trend (Arcadis, 2024). For MW-65, Mann Kendall analysis demonstrated an overall decreasing trend.
However, data from the last five years (Table 7) may be seeing a slight PCE concentration increase at
MW37. This could be a temporary fluctuation from the secondary/IGA plume. More monitoring is
needed overtime along with the upcoming hydraulic and soil investigations, to determine potential
interactions of the secondary/IGA plume and confirm these trends are related to IGAs plume, the Site,
or both. As discussed in the Issues/Recommendations section below, a hydraulic investigation to
delineate the secondary/IGA plume is planned to begin this fall (Appendix L), from which the PRPs will
generate and evaluate data, followed by submission of a written report for Agency review. In the
meantime, the EPA recommends a new sentinel well North of Mort Street be installed to monitor any
potential future plume movement.

Site CUG for PCE is 0.7|ag/L (federal EPA MCL is 5|_ig/L); all numerical values above are above the Site
CUG.
GSI compliance wells within the Chem Central plume area include MW-54A, MW-54B, MW-59,
MW-62, and MW-66. During the last five years MW-62, and MW-66 compliance wells have had some
exceedances of vinyl chloride, but the last exceedance was in 2021, further discussion below (Arcadis,
2024b). The 2019 FYR saw a likely increasing TCE trend for MW-54A and a statistically significant
increasing trend at MW-54B (EPA, 2019). The MW54A and B wells have observed no detections above
the CUG of 3|ag/L in the last five years, although there have been sporadic low-level detections (once
for MW-54A in 2019, twice for MW-54B in 2022). Both MW-54A and B have observed levels of PCE
above the CUG (0.7|ag/L) in a range from l.l-3.6|ag/L consistently since 2019. The MW-59 well has
observed no COC detections in the last five years.
Vinyl chloride was first detected above the CUG (0.02|ag/L) in MW-62 during 2017 and again more
recently during 2020 and 2021 sampling events (Arcadis, 2024b). Vinyl chloride was detected above
the CUG at MW-66 from 2017 to 2020 (MW66 was installed late 2016); since then, it was observed
above detection limits once in the spring of 2023 (at 1.2 |ag/L). It can be expected that as PCE, TCE, and
DCE breakdown that an increase in vinyl chloride concentration would be observed at downgradient
wells. The MW62 and MW66 well are not the most downgradient Site wells and therefore the EPA
recommends comparable wells further downgradient such as the MW54A, MW-54B, and MW-59 wells
should continue to be monitored for vinyl chloride to track potential contaminant migration. Overall,
these compliance wells have observed less Site COC concentrations than the previous FYR reported.
This may support the PRPs interpretation that the Site's impacted shallow groundwater area may be
decreasing in size (Appendix B, B5-9). The EPA recommends continued monitoring of the shallow
aquifer plume trends and additional evaluation of the deep aquifer.
Wells MW-55A and MW-55B have been used as additional compliance wells and are located at in the
most northern component of current monitoring, where mainly PCE is observed. Consistent with the
2019 FYR, PCE has consistently exceeded the clean-up goal (0.7 |ag/L) in these wells and was observed
once above DW criteria (5 |ag/L). From 2019 to present, PCE concentrations at the MW55A well ranged
from 2.2-5.5 |ag/L with only one observation above 5 |ag/L. For the MW55B well PCE concentrations
ranged from 3.3 to 7.2|ag/L and have been intermittently above 5 |ag/L since 2016. No other COC clean-
up goal exceedances were noted in these wells.
The Site groundwater plume and VOC exceedances (of the drinking water criteria used in the PD/GSI
reports) are mapped in Appendix B, B5-9. The highest VOC concentrations, interpreted as relating to
the Chem Central plume, are consistently centered near the MW-21 well cluster. The less than 25 |ag/L
total VOC concentration isocontour has been interpreted by the PRP to not extend as far North as
25
-------
previously mapped, with the belief that the further downgradient contamination observed (mostly
PCE) is from the Eastern IGA plume migration. The EPA recognizes that observed shallow groundwater
contamination generally changes from mixed LNAPLs and DNAPL daughter products upgradient to
mostly PCE (a parent compound) further downgradient, which is not what is typically expected. The
EPA has approved a hydraulic investigation which is needed to confirm the source of the most
downgradient PCE contamination and determine its origin; this work is expected to begin fall of 2024
(EPA, 2024b). The neighboring PCE/daughter product plume (secondary/IGA plume) appears to begin
upgradient of the Chem Central property from the IGA building but may have more than one source.
The primary plume and IGA plume may begin to comingle near 28th street and noted upcoming
investigations will further assess these delineations, as well as extent of deeper aquifer impact.
The 2023 Fourth Quarter PD/GSI Groundwater Monitoring Program report (Arcadis, 2024) calculated
the percent reduction of total VOCs for the following wells: MP-1, MP-2, MP-3/3R, MP-6, MP-7, MW-
16A, MW-16B, MW-21A, PW-1/1R, PW-2/2R, PW-3R/3RR. This analysis compared the concentration of
total VOCs from the most recent sampling in October 2023 to the concentration of total VOCs during
first the sampling event in 2008 for each well. These wells are located within the most upgradient and
southern end of the Chem Central plume on the Univar USA, Inc. and the Consumers Power properties.
The results of this analysis are summarized in Appendix H; HI, for the PD/GSI. From 2019 to 2023 these
wells have consistently observed overall percent reduction in total VOCs meaning that the
concentration of total VOCs has decreased since the first sampling event in 2008.
Total VOC percent reduction calculations are run quarterly, meaning each well listed above had its
percent reduction run 20 times during this review period. The wells had a large majority of positive
percent reductions in total VOCs ranging from 4% to 100%. This range does not include rare occasional
fluxes of total VOCs in past five years where percent reduction was negative, such as: once in the MP-7
well in 2022, twice for MP-16B in 2019 and 2022, once for MW-21A in 2019, once for PWlr in 2019,
and three times for PW2r in 2019 and 2020 (Appendix H; HI & H2). Although majority total VOC
reductions may indicate that the shallow groundwater near the source area is decreasing in
concentration, further analysis of the deeper aquifer is needed to confirm that the potential cause of
these reductions is not from the contamination migrating vertically down.
As discussed in the 2019 FYR, several compounds not identified as COCs have been detected in
groundwater above the MCLs. These include isopropylbenzene, propylbenzene, 1,2,4-
trimethylbenzene, and 1,3,5-trimethylbenzene. The most recent sampling results from October 2023
still saw these compounds above MCLs, except for isopropylbenzene which was present below its MCL
of 800 |ag/L ranging between 39.9 - 90.6 |ag/L (Arcadis, 2024a). This FYR recommends that the EPA
determine if a decision document, such as an ESD, is necessary to capture these additional COCs once
an updated CSM and risk assessment is completed (this could also include evaluation to update select
CULs with new Michigan GSI Criteria (Table 6)).
Extraction wells including PW-1R, PW-2R, PW-3RR, PW-4, PW-5, and SCH-2 are discussed further in the
Groundwater Treatment System Data section below.
Emerging Contaminants
26
-------
1,4-Dioxane
The PRPs sampled 8 select monitoring wells for 1,4-dioxane in 2014 (MW16a-b-c, MW21a-b, PW1,
PW2, SCH-2). All eight locations did not observe 1,4-dioxane above the given detection limits (1.0|ag/L).
The 2019 FYR recommended additional sampling and EGLE and the EPA are requesting the additional
samples be taken out of an abundance of caution to account for the miscible and fast-moving nature of
the compound (EPA, 2019). To ensure potential 1,4-dioxane would not have migrated to other
groundwater areas sampling is still recommended for a few additional central wells (PW5, MW21A&C,
MW16C, MW24A&B, MW56B, MW29A&Br), comparably deeper wells, and further downgradient
wells.
PFAS
As discussed in the 2019 FYR, PFAS compounds were detected in the groundwater extraction system
effluent in July 2018 and January 2019. The concentrations of observed PFOA ranged from: 0.00849 -
0.00906 |ag/L (~8- 9 ng/l) during the July 2018 to January 2019 sampling events, and PFOS
concentrations ranged from 0.0109 to 0.0136 |ag/L (10-13 ng/L) (EPA, 2019). As of spring 2024 the EPA
has established PFOA and PFOS as hazardous substances under CERCLA and established MCLs at 4
ng/L. The 2018-2019 PFOA and PFOS concentrations were above these MCLs. The EPA recommends
sampling the Site groundwater for PFAS to determine the extent and potential interactions with the
Site. This work is still needed. Although PFAS compounds are ubiquitous and may not be sourcing from
the Site, understanding potential PFAS interactions at the Site will be important for considering future
Site remedy expectations.
Groundwater Treatment System Data
The groundwater extraction system influent is treated via an air stripper and discharged to the
POTW effluent Outfall 001. Outfall 001 has been sampled 10 times in the last five years. There have not
been any exceedances of the permit discharge limits reported in the effluent sampling during that time
(Arcadis, 2024a). Historical analytical results for the effluent monitoring were summarized and
compared to permit limits, seen in Appendix M. In 2018-2020 effluent sampling included screening for
PFAS, and low levels of PFAS compounds were observed. PFOA results up to 9.11 ng/L and PFOS
concentrations up to 13.6 ng/L was observed; both above the MCLs of 4 ng/L, see Table 8 below.
Follow-up sampling for PFAS is still needed to determine if this contamination is Site related and is
included in the Issues and Recommendations section.

No influent data (pre-treatment) is collected for the groundwater extraction and treatment system;
however, groundwater quality data collected from the extraction wells PW-1R, PW-2R, PW-3RR was
evaluated. The total VOCs for each extraction well were calculated by summing the detected results for
all VOCs. An evaluation of COC trends since 2018 is presented in Appendix H; H2. The extraction
concentration trends for PW-1R, PW-2R, PW-3RR are shown to be decreasing.
The 2019 FYR discussed that an evaluation of the extraction system demonstrated the extraction rates
at the time were insufficient to exert hydraulic control due to higher yields from the aquifer. The
review expressed concern that the extraction system was not achieving the RAO of preventing the
plume from expanding, nor preventing impact to Cole Drain. The PRPs have submitted a workplan
which includes installing stream gauges in Cole Drain to assess potential interactions. The EPA notes
that if contamination is observed above CUGs north of 28th St., the abandoned extraction well PW4
may need to be replaced and to reinitiate extraction for the original purpose of preventing impact to
Cole Drain, and to also assist in preventing further plume migration to the North (see more below).
Findings from the proposed investigations (soil and deeper aquifer) will aide in determining if the
extraction system requires further optimizations and if the abandoned PW4 indeed needs
replacement.
The PRP's capture zone analysis (Arcadis, 2024) shows that the currently operating pumping wells PW-
1, PW2, and PW3r (it did not include PW5 in the analysis) would not have influence or capacity to
capture any groundwater North of 28th St. (Appendix I, II). Although the PRP's quarter 4 of 2023 and
quarter 1 of 2024 did not observe groundwater contamination in these northern pumping wells,
(excluding PCE), COCs were observed in 2023 at low levels downgradient. At well MW66 COCs such as
1,1-DCA (1.5|ag/L), cis-l,2-DCE (1.5|ag/L), and vinyl chloride (1.2|ag/L) were observed during the 2023
quarter 2 sampling event and had also previously been detected during quarter 4 of 2020. These
sporadic detections may be related to rebound or seasonality. Continued sampling of the MW66 well is
appropriate to monitor such fluctuations and determine any potential trends or causes.
The detections suggest groundwater contamination related to the Site may still be present North of
28th street at low levels. The observed 1,1-DCA & 1,1-DCE concentrations are below MCLs and CUGs,
and the vinyl chloride detection is below MCL (2 |ag/L) but above CUG (0.02 |-ig/L). Sampling of the
Northern wells (ex. MW60, MW66) should continue quarterly to monitor for future potential
contaminant migration. If future Site related detections occur at these wells a replacement extraction
well for PW4 may be needed to capture any remaining northern groundwater contamination.
28
-------
In addition, the 2019 FYR determined that the screened intervals of the pumping wells may result in
inefficient extraction of contaminants due to dilutions. The 2019 FYR Hydrogeologic Analysis found
that extraction wells PW-1, PW2, and PW3r, which go to a depth of 25-30 ft. bgs with 10 ft. screens,
may be placed slightly below where the highest concentrations of light non-aqueous phase liquids
(LNAPLs) have been observed by the main Univar building (from the water table to about 25 ft. bgs).
Recent sampling results (Arcadis, 2024a) demonstrate that the shallower monitoring wells adjacent to
the plume core's extractions wells (i.e., MW16A, MP1, and MP2 compare against PWlr and MW21A
compares against PW2) have been more likely to observe the Site's most common LNAPL groundwater
contamination, see Appendix I; 12. This supports the 2019 FYR Hydrogeologic Analysis findings.
Therefore, the EPA recommends using results from the upcoming soil investigation to confirm zones of
highest LNAPL contamination and evaluate the potential need of an additional pumping well near the
main Univar building with a screened depth between the water table and ~18ft bgs to capture the
upper zone of LNAPL contamination in this area.
The EPA also notes wells downgradient of the MW21 set and PW2r (i.e., MW24 wells nest screened
between 25-38 ft bgs) may not be screened at depths which would be more likely to observe the
shallow contamination. Although sampling at the northernmost plume has not seen these LNAPL
compounds at the most northern extent of shallow wells by Mort St., the EPA recommends shallow
groundwater delineation which may include installing another set of shallow monitoring wells adjacent
to the MW24.
Deep Aquifer Groundwater
As previously mentioned, extraction well SCH-2 was located in the deeper aquifer (about 45ft bgs)
adjacent to the main Chem Central building. PRP groundwater investigations conducted in 2020
observed Site COCs in the deeper aquifer. The SCH-2 well was proposed for closure to prevent a future
conduit for contaminants to migrate to the deep aquifer. The EPA approved the SCH-2 for closure and
replacement, and the well was replaced by well PW-5 in 2022. SCH-2 is scheduled to be abandoned in
fall of 2024. PW5 is sampled quarterly, and since its installation has consistently seen extremely high
levels of 1,1,1-TCA, 1,1-DCE, cis-l,2-DCE, ethylbenzene, PCE, toluene, DCE, vinyl chloride and sporadic
very high levels of xylenes, and 1,2,4-TMB (Arcadis, 2024); See Table 9 below and Appendix G 2019-
2023 summary results.
A deep aquifer investigation is being planned to delineate the full extent of contamination. As there
are no known residential drinking wells within a mile downgradient to the site (Appendix B, B10) the
EPA notes there is no known human exposure via groundwater ingestion at this time. The Site ROD did
not include preventing future migration to the lower aquifer as an objective, but it did include the deep
SCH-2 extraction well (now replaced by PW-5) to address lower zones of contamination observed in
the Rl. The recent deep groundwater sampling results may indicate a larger and continued impact to
the lower aquifer. Observing Site COCs at such high concentrations (12-6,100 times above drinking
water criteria, see Table 9) may require a change to the site remedy to capture the contamination and
prevent further deep groundwater migration. The upcoming deep aquifer investigation(s) will aide to
determine potential optimizations needed for the Site's remedy.

Groundwater Geochemistry Data
The PMP includes the quarterly monitoring of MP-1, MP-2, MP-3R, MP-6, MP-7, MW-16A and
MW-16B for VOC as well as geochemistry data including dissolved oxygen (DO), pH, conductivity,
oxygen-reduction potential (ORP), total iron, and total manganese. Extraction wells PW-1, PW-2, and
PW-3RR are also sampled for DO, pH, specific conductivity, and ORP. The average geochemistry from
2019-2023 are summarized in Table 10 and historic results are presented in the PD/GSI groundwater
monitoring report included in Appendix H; HI (Arcadis, 2024a). The October 2023 geochemistry result
was selected as a most recent sampling event which is generally representative of these parameters
during the last five years.
In the wells sampled during this review period, majority low DO levels (less than 1 mg/L) and ORP
levels less than 50 millivolts (mV) averages are seen, which support a reductive pathway. The pH
results are near neutral (7) and the specific conductivity results are within the normal range for
groundwater. High total iron levels have been detected in several wells and iron-stained discharge has
been noted along the east bank of Cole Drain. The 2019 FYR recommended sampling downgradient
sentinel and compliance wells (PZ6B, and PZ7A-B) for total iron. Currently the PRP is sampling some
wells at the start at of the plume for total iron. GSI compliance and sentinel wells named above should
also be analyzed for total iron to evaluate the downgradient plume area.
Well PW3rr has had the comparably lowest pH results. Historically the pH at this well is close to neutral
and the other two sampling events during 2023 saw neutral pH at the PW3rr well also (Arcadis, 2024a)
(Appendix H; HI). Further monitoring at this well is needed to see if any future trend for its
geochemistry is established.

Surface Water
There is no recent surface water data to review. However, groundwater data supports that Cole Drain
is gaining reach and the Site ROD established preventing discharge to the drain as an RAO. The ROD
established understanding that the Site's shallow groundwater flows North and parallel to Cole Drain
and then begins to discharge to the creek "around 700ft north of 28th St" (WES, 1990). However, a
defined picture of any discharge or underflow has not been conducted, and the EPA believes additional
monitoring wells along Cole Drain would confirm the Site groundwater to surface water interactions.
Future surface water sampling of Cole drain may be needed.
To assess potential impact to Cole Drain, the EPA compares highest compound concentrations
observed in relevant compliance and sentinel wells north of 28th St. (in the last five years) to Site CUGs
and GSI criteria (see Table 11 below). GSI criteria has been used at the Site for updated evaluation of
potential impact to surface waters that includes factoring in the impact of a mixing zone where
groundwater discharges to surface waters (EPA, 1999).
In the event that Site groundwater discharge to Cole Drain was confirmed, the creek is not being used
as a drinking water source for human receptors. There have been no observed human recreational
activities in the Creek. For ecological concerns, the main Site related COC observed above CUGs is vinyl
chloride at wells MW29a and MW40r. The PCE & TCE occasionally observed may be associated with
the Eastern IGA plume (the hydraulic investigation beginning in the fall of 2024 will aide to confirm
this). Although vinyl chloride has been detected above Site CUGs in the last five years, its last
31
-------
detections were in 2020 for MW29A and 2021 for MW40r. These wells have most recently had 8
rounds of quarterly sampling result that were non-detect for vinyl chloride.
Additionally, there have been no COC concentrations past 28th St. observed above GSI criteria in the
last five years (Table 11), GSI criteria has been used as an additional gauge to measure potential
surface water impacts and includes a calculated adjustment to the mixing zone (EPA, 1999). This could
indicate that even if any direct discharge to the creek is occurring, concentrations are not high enough
to threaten unacceptable ecological risk by the Site from discharge to Cole Drain. The EPA recommends
continued monitoring of northern compliance and sentinel wells, as well as installing some additional
monitoring along Cole Drain to ensure contamination is not discharging to the creek. If contamination
is observed above CUGs at these wells in the future, sampling of the creek to assess for potential
impacts may be necessary.

Soil Vapor Extraction System Data
32
-------
The SVE system effluent is routinely field-tested with a photoionization detector (PID). Quarterly SVE
system effluent air samples are collected and analyzed for VOCs via USEPA Method TO-15 and non-
methane organics via USEPA Method TO-12. The total VOC concentrations are included in Appendix H;
HI. The SVE effluent data from October 2019 through October 2023 included total VOC concentrations
ranging from 49.5 to 3,950.0 |-ig/m3.
The SVE system effluent air sample data is used to assess compliance with the EGLE Air Quality
Division "Substantive Requirements Document". The 12-month rolling average emission limit of 0.016
tons per year of VOCs was calculated for 2023 (Arcadis, 2024a). The 2019-2023 emissions data is
summarized in Appendix J; Jl. The system operates consistently well within this limit of 5.4 tons per
year. No additional data is reported to allow for the evaluation of the SVE system including individual
extraction point flow rates/effluent concentrations, vacuum readings in surrounding monitoring points
to evaluate the system radius of influence, or soil sampling data to evaluate the remedial progress for
vadose soils.
Over the last ten years there have been efforts to review and optimize the Site remedies, including
evaluating the SVE system. A summary of which laterals (see Appendix B4), and extraction wells were
operated during these optimization efforts is provided below:
• June 2014 - April 2017: SVE laterals A, B, D, E were operating.
• April 2017 - Sept. 2020: SVE laterals C & D were operating.
• September 2020 - present: all SVE laterals and extraction wells are operating.
The 2019 FYR recommended that SVE pulsing should be tested at the site to improve remedy efficiency
and reduce potential vapor pathways. The PRPs have created a SVE pulse test workplan and it is
currently under review by the EPA. This SVE testing proposal includes evaluating SVE optimization, re-
use, or potential future shutdown of the SVE system. The workplan considers how the SVE testing
results may be used to better understanding any potential remaining COC concentrations and/or
sources in the soil. The Site team expects the initial SVE testing will take approximately three months
before further SVE recommendations can be made. The 2019 FYR addressed concern that the SVE has
not been performing as intended and its effectiveness needed to be reviewed; this pulse test should
also aide to scope and address this concern.
Vapor Intrusion Sampling
A vapor intrusion assessment has been completed at the Site. Vapor intrusion sampling has occurred
from 2018 to 2023 and included several follow-up sampling events where further evaluation was
needed. At a few locations where indoor air COC concentrations occasionally exceeded the EPA VISLs,
follow up sampling included confirmation sampling, and evaluating for seasonal trends and complete
pathways. Follow-up sampling methods included paired indoor air and sub-slab sampling at locations
of interest, and utility corridor sampling to check for potential utility pathways. The results did not
observe any completed vapor intrusion pathways of Site related COCs. Based off all the cumulative
results, the EPA determined there was no unacceptable Site related vapor intrusion risk at this time
(EPA, 2024). The one VISL exceedance consistently seen was for chloroform at a neighboring business.
Since chloroform isn't associated with the Site and was known to be used with that business's
33
-------
practices, it was determined to be unrelated to the Site (Arcadis, 2023e). Figures summarizing the
vapor intrusion work and findings can be found in Appendix K.
Soil
Soil sampling was not a part of the remedy or performance monitoring for the Site and has not
occurred in the last five years. However, due to high levels of COCs still being observed in groundwater,
as well as recommendations from the 2019 FYR, a soil investigation is planned to kick off in the fall of
2024 to scope for any potential remaining sources that were undiscovered in the Rl (Appendix L; L2).
The EPA and PRP acknowledge that the Rl did not consider sampling under the Univar building, that the
SVE system does not extend to the Eastern portion of the building for gauging purposes, and that
although no full vapor intrusion pathways were observed, the Eastern portion of the main Univar
building observed the most vapor intrusion concentrations above detection levels. The first approved
phase of the soil investigation is proposed to focus on the East and West sides of the main Univar
building. Additionally, the soil investigation includes sample locations in the vicinity of the SVE system
with the purpose of reviewing future potential SVE system shutdown or modifications for optimization.
The results of the soil investigation and any subsequent work will be used to update the conceptual
site model and scope future Site remedy needs.
Site Inspection
The inspection of the Site was conducted on 4/3/2024. In attendance were Alyssa Graveline, EPA RPM;

V. TECHNICAL ASSESSMENT
QUESTION A: Is the remedy functioning as intended by the decision documents?
Question A Summary:
No. The remedy is not fully functioning as intended in the ROD, but currently no unacceptable Site risk
is observed.
Based off the state's well database, there are currently no known uses of groundwater within a mile
radius of the site. ICs that the ROD included have been implemented on three of the nine parcels to
prevent ingestion and direct contact with contaminated soils and to prevent ingestion of contaminated
groundwater. Completing ICs for the remaining parcels is underway. The remaining parcels are used for
commercial business to the north of 28th Street. At this time there has been no indication that soil
contamination would be present north of 28th St.
Exceedances of COC cleanup levels in the GSI sentinel wells, as well as now observed in the deeper
aquifer, indicate that the groundwater plume is not fully contained. New information of contamination
to the deeper aquifer is not expected to impact human health or the environment currently, as the
area is connected to municipal water and no drinking wells are observed within a mile downgradient to
the site, but this may be able to impact future protectiveness if not addressed. Additionally, as the
2019 FYR established, although the extraction system has been returned to full function, there are
continued observations of high concentration of contaminants outside the extraction systems area of
influence. As the downgradient contamination is unlikely to be addressed by the current remedy,
additional optimizations may be necessary in order to achieve remedial objectives.
Finally, the 2019 FYR addressed the need for an additional soil source investigation, which is now
planned to begin in the fall of 2024. Although the EPA believes no current unacceptable risk related to
the Site is occurring because soil contamination would not likely leave the source area, these activities
are needed to ensure long term protectiveness. Short term protectiveness is ensured by access
restrictions, ICs which include soil disturbance restrictions, and the municipal drinking water supply for
nearby areas.
Remedial Action Performance
Upcoming planned investigations for the site including the soil, secondary plume, deeper aquifer, and
SVE studies will help to determine effectiveness of the current remedial operations. The CSM updates
will be used to ensure future potential remedy optimizations meet remedial action goals to achieve
cleanup levels in a reasonable time frame, control groundwater migration (laterally and vertically), and
improve the operations of the treatment system. Future work should also consider potential
modifications to the current groundwater sampling schedule and Site goals.
System & Maintenance Operations
35
-------
System operating procedures associated with the groundwater treatment and SVE systems are
implemented on both a routine basis, as required, to ensure systems continue to operate, and on an
as-needed basis for optimization purposes. These optimization strategies are intended to improve the
system functionality with component improvements, and to modify operational strategies to improve
contaminant capture. As discussed previously, recent data indicates the SVE system is no longer
performing effectively and that upcoming studies with pulsing will be used for remedy evaluation.
Other remedy actions such as the groundwater extraction may also need adaption based off future
CSM updates.
Also discussed below in the Issues/Recommendations section and above in Progress Since The Last
Review section, is the need for a contingency plan to be developed that considers actions for when the
remedial systems experience periods of down time. The plan should include how groundwater
containment will be maintained and what actions need to be taken to protect downgradient receptors.
Implementation of Institutional Controls and Other Measures
There have not been any noted compliance issues on the three parcels that currently have ICs in place
(parcels 2, 3, and 6) and the ICs are effective in preventing exposure, including restricting groundwater
use and new drinking well installation. However, ICs are needed for the six remaining parcels. Parcels
are identified in Appendix D. EGLE is currently reviewing the ICs drafted by Univar USA, Inc. The 2018
building expansion on the property adjacent to the DynaPlate across the Cole Drain destroyed
monitoring wells, MW-42A, MW-42B, and MW-42C, which underscores the importance of recording
the additional ICs without further delay. Once further analysis of the side gradient IGA plume is
completed the Site team will evaluate if these wells need to be replaced. Access controls such as
fencing and warning signs are present around the Site and in mostly good condition (see Other
Findings).
The EPA has not observed any immediate threats at the Site. Recent concerns have been vapor
intrusion and potential remaining soil contamination near the original source. The upcoming soil
investigation will be used to determine if any soil contamination source remains by the main Univar
building, but only workers have limited access to the property and are unlikely to handle Site soil. The
vapor intrusion discussion is addressed below.
QUESTION B: Are the exposure assumptions, toxicity data, cleanup levels, and remedial action
objectives (RAOs) used at the time of the remedy selection still valid?
Question B Summary:
No, but currently no unacceptable Site risk is observed. Cleanup levels need to be updated for the Site
to adjust for new compounds detected, and adjustments to previous Site criteria. However, the
cleanup level amendments should occur after the CSM is updated from ongoing investigations to
account for all potential remedy changes needed. This includes further assessment of possible impact
to Cole Drain and its associated environment (prevention of Cole Drain impact is a RAO, see more
below), investigating potential presence of emerging contaminants at the Site, as well as delineating
36
-------
the extent of deep aquifer contamination. The Site groundwater data is currently compared to the
updated Michigan criteria and federal and state drinking water criteria.
The basic assumptions for exposure to people and the environment (aquatic life in Cole Drain) from
Site COCs remain valid. ROD cleanup levels were set largely based on available ARARs. Due to Michigan
Part 201 GSI criteria updates, the groundwater and soil standards in the ROD for ethylbenzene, 1,1,1-
trichloroethane, and xylene have become more stringent. During this review period, visual
observations of Cole Drain have not indicated adverse impact. Groundwater sampling near understood
areas of surface water discharge suggest Site COCs have not been observed at levels which may harm
the ecosystem, as there have been no northern plume concentrations above GSI criteria in the last five
years. Considering vapor intrusion , no further vapor intrusion sampling is needed at this time as
sampling from 2018-2023 did not observe any Site related exposure pathway completion. For the deep
aquifer data gap, there are no known groundwater residential wells within a mile downgradient of the
Site.
Emerging Contaminants
1,4-Dioxane & PFAS
Past sampling of select wells did not observe 1,4-dioxane but additional sampling is recommended out
of an abundance of caution to account for the miscible and fast-moving nature of the compound (EPA,
2019). To ensure potential 1,4-dioxane would not have migrated to other groundwater areas sampling
is still recommended for a few additional central wells, comparably deeper wells, and further
downgradient wells.
PFAS compounds have been detected in the groundwater extraction system effluent. PFOA
concentrations have ranged from: 0.00849 - 0.00906 |ag/L (~8- 9 ng/l), and PFOS concentrations from
0.0109 to 0.0136 |ag/L (10-13 ng/L) (EPA, 2019). As of spring 2024, PFOA and PFOS are hazardous
substances under CERCLA with MCLs at 4 ng/L. The 2018-2019 PFOA and PFOS concentrations were
above these MCLs. The EPA recommends sampling the Site groundwater for PFAS to determine extent
and potential interactions with the Site. Although PFAS compounds are ubiquitous and may not be
sourcing from the Site, understanding potential PFAS interactions at the Site will be important for
considering future Site remedy expectations and needs.
Are There Newly Identified Source Areas Leading to a Potential Pathway Not Previously Addressed by
the Remedy?
A soil investigation workplan has been approved by EPA to aide in determining if any source may be
remaining underneath the main Site building. However, even if this is confirmed there is no
expectation this would change exposure pathways. The most common exposure pathway known for
under building contamination is vapor intrusion, which has been investigated with several events at
the Site buildings and the EPA determined no unacceptable Site related risk was occurring at that time.
Are There Toxic Byproducts or Daughter Products Not Previously Addressed by the Decision
Documents?
37
-------
The ROD lists 21 contaminants for the Site's main COCs (EPA, 1991), see Table 1. During the last ten
years, the Site monitoring program has included analysis for at least 75 different VOCs and 75 SVOCs. It
is expected that any byproducts or daughter products which could occur would be captured in this
monitoring effort. This includes the newer compounds detected (isopropylbenzene, n-propylbenzene,
1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, and 1,2-dichloroethene), discussed above in the Data
Review section, which will be considered for future COC additions.
Expected Progress Towards Meeting RAOs
The remedial action performance for the Chem Central Site was determined by evaluating the remedy
against the RAOs presented in the ROD. They are presented and discussed as follows:
Prevent ingestion and direct contact with contaminated soils.
• Status: Progress is being made toward achieving it via completed implementation of ICs
on 3 parcels; ICs are expected to be completed on the remaining parcels by 2026. Access
restrictions such as Site security and fencing are in place.
Prevent possible ingestion of contaminated groundwater.
• Status: Progress is being made toward achieving it via completed implementation of ICs
on 3 parcels, ICs are expected to be completed on the remaining relevant parcels by
2026. Drinking water is sourced by municipal water in the surrounding area.
Prevent movement of contaminants from the soils into the groundwater.
• Status: The SVE system continues to operate. Soil samples have not been collected to
assess the progress of COC concentration in soils toward cleanup goals or if any source
remains near the Univar buildings. Upcoming investigations addressing the soil, deeper
aquifer, secondary plume, and SVE study will aide to determine how contaminants may
have or continue to migrate. These investigations are identified in the
Issues/Recommendations section below.
Prevent the discharge of contaminated groundwater into Cole Drain.
• Status: The 2019 FYR discussed that exceedances of COC cleanup goals in GSI sentinel
and compliance wells may indicate that the groundwater treatment system is not fully
containing the contaminant plume. A few CUG exceedances have occurred in the last
five years on the northern end of the plume for PCE and vinyl chloride. But the vinyl
chloride detections have decreased in frequency and concentration since the last FYR
(not detected north of 28th street in the last two years). Additionally, no COC
concentrations in this period have exceeded the updated GSI criteria which factors in
the mixing zone for surface water.
• If PCE is confirmed to be associated with the eastern IGA plume, then the detections
may not be solely related to the Site. Nonetheless, during this review period no PCE
concentrations exceeded the GSI criteria.
38
-------
• Groundwater contours also indicate that Cole Drain may be gaining in reach. The
upcoming soil investigation includes installing two stream gauges in Cole Drain to
evaluate potential groundwater interaction. This work is expected to begin this fall,
2024 (Appendix L; L2).
QUESTION C: Has any other information come to light that could call into question the protectiveness
of the remedy?
No other information has come to light that could call into question the protectiveness of the remedy.
There have been no observed trends which would imply any local change of climate is impacting the
Site. There have been no observed impacts from natural disasters.

OTHER FINDINGS
In addition, the following are recommendations that were identified during the FYR and (may improve
performance of the remedy, reduce costs, improve management of O&M, accelerate site close out,
conserve energy, promote sustainability, etc.), but do not affect current nor future protectiveness:
• Other Finding 1: The north central gate is damaged and requires repair or replacement.
• Other Finding 2: Downgradient GSI compliance and sentinel wells PZ6B and PZ7A-B should be
sampled for total iron to evaluate geochemistry of the plume at the northernmost extent.
• Other Finding 3: The SCH-2 well needs to be properly abandoned; this work is expected to be
completed in the fall of 2024.
VII. PROTECTIVENESS STATEMENT
OU1 and Sitewide Protectiveness Statement(s)
Protectiveness Determination:
Short-term Protective
Protectiveness Statement:
The remedy at the Chem Central Site currently protects human health and the environment because
it eliminates the principal threat posed by the Site by preventing direct contact with contaminated
materials. Site access restrictions are in place consisting of a six-foot high chain link perimeter fence
with three strand barbed wire and warning signs posted at approximately 200-foot intervals along
the fence. There is no pathway to groundwater exposure as municipal water is supplied to the area,
soil restrictions are in place at the properties where soil contamination is believed to be present, and
current groundwater data suggests any potential discharge to Cole Drain would not adversely impact
the environment.
43
-------
However, in order for the remedy to be protective in the long-term, the following actions need to be
taken to ensure protectiveness:
• Complete environmental covenants for the 6 remaining parcels that comprise the Site.
• Finalize the investigative workplan and determine the nature and extent of deeper aquifer
contamination.
• Update the conceptual site model and complete an updated risk assessment for these
compounds and develop a decision document to include new COCs and CULs at the Site.
• Complete a workplan to delineate the secondary plume and determine whether the northern
component of contaminated groundwater observed at the sentinel wells is related to the
Site. Install a new sentinel well North of Mort St. to monitor any potential future plume
movement.
• For the upgradient component, use results from the planned soil investigation to confirm
zones of highest LNAPL contamination and evaluate the potential need of a new additional
pumping well near the main Univar building with a screened depth between the water table
and ~18ft bgs to capture the upper zone of LNAPL contamination in this area.
For the central downgradient component, the EPA recommends shallow groundwater
delineation and/or installing another set of shallow monitoring wells adjacent to the MW24
nest to ensure full delineation of shallow contamination.
• Install additional monitoring wells along Cole Drain for groundwater/surface water interface
monitoring needs. Future surface water sampling of Cole Drain may be needed.
• Soils beneath the former Chem Central building and paved areas on the former Chem Central
property should be investigated; implement the supplemental soil investigation workplan
that has been approved by EPA.
• Conduct a SVE pulse/ shut-down study, as well as using the additional soil investigation.
Results of these investigations should be used to evaluate remedy effectiveness, optimization
potential, and needs. The SVE pulse testing is expected to begin this fall of 2024.
• Conduct PFAS sampling across the monitoring well network at the Site.
• At a minimum, sample for 1,4-dioxane at the following wells: PW-5, MW-21A, MW-16c, and
MW-24A, MW-24B and MW-24C.
• Complete the Groundwater Hydraulic Investigation workplan to delineate the secondary
plume along the Western edge in relation to the Site, and therefore determine its potential
impacts to the Site. Implement the workplan that has been approved by EPA.
• Develop a remedial action contingency plan. This plan should include how groundwater
containment will be maintained and what actions need to be taken to protect downgradient
receptors.

Letter from CHEMCENTRAL to Paul H. TenPas thanking Mr,
TenPas for forwarding the appraisal and explaining that the need
for the environmental assessment because CHEMCENTRAL's
investigation was comprehensive, but did not focus on specific
down gradient properties nor did it attempt to locate other
contributing sources of contamination and as a result,
CHEMCENTRAL had no direct information regarding
groundwater or soil conditions on the property. CHEMCENTRAL
offered to share the cost of a groundwater assessment on a 50-50
basis.

Letter to TenPas asking for reply. Copy attached.
At the meeting in the offices of the Environmental Protection
Agency in Chicago, it was agreed that CHEMCENTRAL would
make a monetary offer to Kohler, the supposed owner of Parcel 4,
within 6 weeks after the date of the meeting. The offer would be
based upon the appraised value of an underground utility easement
across Parcel 4. The offer was to be made after the EPA agreed
that the amount of the offer based upon the appraised value of a
underground utility easement would constitute
CHEMCENTRAL's best efforts at obtaining acknowledgement of
the restrictive covenants, in the evc~+ that the owner of Parcel 4
rejected the offer.

Letter from McShane & Bowie to Eric Eggan providing Mr. Eggan
the name of the EPA contact, Mr. Michael McAteer and advising
them that the concerns regarding maintenance of the road were
raised with Mr. McAteer who, in concept, has agreed that we could
put a qualification on the soils to be disturbed, such that only those
soils beneath the specified level below the surface would need
prior approval of the EPA. To do this would require amending the
EPA order. Mr. McAteer was making various inquiries as to the
acceptability of making this change and the process necessary to
accomplish it.

CONSUMERS POWER COMPANY, OWNER
There have been numerous contacts with Consumers Power Company regarding its property as
monitoring wells are located on the property. Consumers Power Company's problems with
signing the Acknowledgment are now down to two issues: 1) the need to maintain the electric
lines and transforming equipment located on the property which involves access to and
excavation of the surface soils which the EPA has approved to the depth of 3 feet above points B
and B on attached map; and, 2) CPC needs to see a copy of the 95% clean-up plan as approved
which needs to incorporate EPA revisions.

portion of the effluent pipe was not working,
causing the effluent water line to freeze. The
heat trace was repaired, and the system was
returned to operation on February 15.

From October 25 to November 1, 2021 purge
wells PW-1R, PW-2R, and PW-3RR were
redeveloped to address well performance. This
well maintenance focused on increasing well
pumping capacity by managing mineral
accumulation in the well screen and filter pack.
The purge wells were redeveloped using a
combination of mechanical surging and well
development chemicals.

Two power outages contributed to system
downtime. The first power outage resulted in a
to-day shutdown from July 23-25. The second
power outage lasted approximately 1 day
(August 28-29) but resulted in a 14-day
shutdown due to equipment damage. During
system inspection and troubleshooting identified
an issue with the air stripper transfer pump
wiring and the surge arrestor for the PW-2R
transducer. Repairs were completed and the
system was restarted on September 12. PW-2R
was brought back online September 20 after the
replacement surge arrestor channel was
installed.

One 5-day system shutdown occurred from
October 5-10, 2022, due to a failed pressure
switch which was replaced, and the system was
restarted October 10, 2022.

Sampling Date
Notes:
1. At least four independent sampling events per well are required for calculating the trend. Methodology is valid for 4 to 40 samples.
2. Confidence in Trend = Confidence (in percent) that constituent concentration is increasing (S>0) or decreasing (S<0): >95% = Increasing or Decreasing;
> 90% = Probably Increasing or Probably Decreasing; < 90% and S>0 = No Trend; < 90%, S<0, and COV > 1 = No Trend; < 90% and COV < 1 = Stable.
3. Methodology based on "MAROS: A Decision Support System for Optimizing Monitoring Plans", J.J. Aziz, M. Ling, H.S. Rifai, C.J. Newell, and J.R. Gonzales,
Groundwater, 41 (3):355-367, 2003.

Notes:
The system operates under the substantive requirement document (SRD), dates March 2008. The SRD was
modified on November 1, 2018, which indicates that the system is subject to Michigan Air Pollution Control Rule
(MAPCR) R 336.1291 (Rule 291) exemption requirements. The modified SRD no longer includes the monthly
emissions tracking requirement and was replaced by the requirement to maintain accurate potential to emit
(PTE) calculations, demonstrating compliance with the Rule 291 emissions thresholds.
Emissions calculations are based on effluent (combined air stream from the SVE and air stripper) vapor samples.
VOC: Volatile Organic Compound

the physical nature and condition of any facility associated with the remedy. An example would be soil vapor
extraction.
XI. OVERALL OBSERVATIONS
A.
Implementation of the Remedy
12
-------
Describe issues and observations relating to whether the remedy is effective and functioning as designed.
Begin with a brief statement of what the remedy is to accomplish (i.e., to contain contaminant plume,
minimize infiltration and gas emission, etc.).
The remedy was designed to protect public health and the environment from
unacceptable risks associated with the potential ingestion of or direct contact with
contaminated soils, the potential ingestion of contaminated groundwater, the
movement of contaminants from the soils into groundwater, and the discharge of
contaminated groundwater into Cole Drain. The groundwater treatment system was
designed to capture and treat groundwater to prevent migration of the plume and
reduce contamination in groundwater. However, during downtime of the groundwater
treatment system the contaminant plume is not captured and may allow for
contaminant migration. The groundwater treatment system and SVE system have both
been operating longer than anticipated during the ROD. System performance will be
further evaluated in the five-year review
report.
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.
Remedial systems have operated longer than the anticipated clean up times
stated in the ROD. System failures have caused system down time where the
groundwater contaminant plume was not being captured. EPA is collaborating with the
group to generate an official contingency plan.
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.
The SVE system has not aided the site remedy in several years and adds a time
and cost burden that may be unnecessary for the site. A workplan to test SVE pulsing
and/or temporary shut-downs to the SVE system for possible remedy optimizations is
under collaboration with the state & PRP.
13
-------
D. Opportunities for Optimization
Describe possible opportunities for optimization in monitoring tasks or the operation of the remedy.
No opportunities for optimization in monitoring tasks or the operation of the remedy
were noted during the site inspection. However, EPA is collaborating with the PRP to discuss
possible future Remedy optimizations.
