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 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 Oil and Hazardous Substances Pollution Contingency Plan (NCP)(40 CFR
Section 300.430(f)(4)(ii)), and considering EPA policy.
This is the sixth FYR for the MIDCO I Superfund Site ("Site"). The triggering action for this statutory
review is the completion date of the previous FYR, September 12, 2019. 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 three operable units (OUs), all of which are addressed in this FYR. OU1 addresses
the groundwater remedy, OU2 addresses the soil and sediment remedy, and OU3 addresses the final
cover for the Site.
The MIDCO I Superfund Site FYR was led by Jeffrey A. Dewey, EPA Remedial Project Manager (RPM).
Participants included Karen Chen, EPA Community Involvement Coordinator; Amy Gahala, United
States Geological Survey Hydrologist (technical adviser to EPA); Matthew LeFauve, EPA Ecological Risk
Assessor; and Stephanie Andrews, the Indiana Department of Environmental Management (IDEM)
Project Manager. The MIDCO Remedial Corporation (MRC) was notified of the initiation of the FYR. The
review began on 9/8/2023.
Site Background
The Site's source property occupies approximately four acres located at 7400 West 15th Avenue in
Gary, Lake County, Indiana (see Figure 1 in Appendix B), but the waste management area and
perimeter fence has been extended to enclose approximately seven acres that include the
groundwater treatment plant and contaminated sediment areas. The Site is in an area of mixed use for
commerce and light industry. It is within 1,500 and 3,000 feet of residential neighborhoods in
Hammond and Gary, Indiana, respectively.
The Site is bordered on the west by an Indiana Department of Transportation (INDOT) salt storage
facility, on the north by the 9th Avenue Dump Superfund Site, on the east by Gary Material Supply
Company, and on the south by commercial buildings. The Site is approximately 3.7 miles south of Lake
Michigan and lies halfway between the Grand Calumet River and the Little Calumet River. The Calumet
aquifer is approximately 30 feet thick at the Site and is underlain by 110 feet of silty clay and silt loam.
Use of the Calumet aquifer is minimal because the predominant source of residential and industrial use
water in the area is Lake Michigan.
In the 1970s, the Site was used for industrial waste storage, recycling, and disposal. In 1976 a large fire
5
-------
destroyed an estimated 14,000 drums containing chemical wastes, with an estimated additional 14,000
drums brought to the Site from 1977 to 1979. The operations at the Site resulted in soil, sediment, and
groundwater contamination. EPA placed the Site on the National Priorities List (NPL) in 1983.

II. RESPONSE ACTION SUMMARY
Basis for Taking Action
The following contaminants of concern (COCs) have been identified at the Site: volatile organic
compounds (VOCs); semivolatile organic compounds, such as polynuclear (polycyclic) aromatic
hydrocarbons (PAHs); pesticides; polychlorinated biphenyls (PCBs); and inorganic constituents,
including lead and cyanide. The full list of COCs requiring remediation in soil, sediment, surface water,
and groundwater for the Site is found in Table 1 below.
6
-------
The December 1987 Remedial Investigation (Rl) for the Site included the evaluation of the Site
hydrogeology, as well as extensive sampling of groundwater, source area subsurface soils, and surface
sediments in the surrounding Site wetlands (1987 Geosciences Inc & ERM Inc). The Rl demonstrated
that the source area soils and nearby groundwater were highly contaminated and presented significant
human health risks via ingestion of groundwater or soils for to nearby property owners (as of 1987)
and future residential use of the Site if the Site risks were not addressed. In addition, the ecological risk
assessment demonstrated risks to biota including fish, crayfish, snapping turtles, small mammals, and
earthworms in the vicinity of the Site. It was determined that continued migration of contamination in
groundwater could eventually reach down-gradient residential wells, and therefore needed to be
addressed with response actions.
As presented in the 1987 Rl, due to the presence of the nearby INDOT salt storage facility which
bounds the West side of the Site and is hydrologically upgradient of the Site, a limited portion of the
Calumet aquifer in the immediate vicinity of the Site is highly saline as a result of sodium chloride
discharges. As such, the aquifer surrounding the Site is being treated as a Class 2b potential drinking
water aquifer due to its salinity. Chloride is detected as high as 15,000 milligrams per liter (mg/L) in
groundwater below the Site (1987 Rl by Geosciences, Figure 5.24 PDF page 309). Ocean water contains
approximately 20,000 mg/L chloride.
Response Actions
In 1981, EPA installed a fence around the initial source area of the Site. In 1982, EPA conducted a
three-phase time-critical removal action to remove and send off-site for disposal all surficial wastes
(including thousands of drums and a number of tanks) and the top 6 to 12 inches of soil. EPA installed
an interim clay cover over the Site.
EPA selected a remedial action for the Site in a 1989 Record of Decision (ROD) (1989 EPA) and made
fundamental changes to the selected remedy in a 1992 ROD Amendment (1992 EPA). EPA issued four
subsequent Explanations of Significant Differences (ESDs) in 1996, 1999, 2004, and 2015 to document
significant changes to the remedy. Most recently, EPA issued a 2022 ROD Amendment to
fundamentally change the selected groundwater remedy at both this Site and the MIDCO II Superfund
Site (MIDCO II) (2022 EPA).
The remedial action objectives (RAOs) for the selected remedial action in the 1992 ROD Amendment
are as follows:
a. Eliminate direct contact threat from contaminated source area soil and sediments;
b. Treat the principal threat in soil to substantially reduce the threat of groundwater
contamination and the direct contact threat;
c. Prevent off-site migration of contamination in groundwater;
d. Assure that contaminants do not adversely affect biota; and
e. Clean up groundwater to achieve groundwater cleanup action levels (GWCALs).
The 2022 ROD Amendment altered the RAOs for OU1, the groundwater cleanup remedy, for both this
Site and MIDCO II as follows:
a. Protect human health by eliminating exposure via ingestion of COCs in groundwater above
levels that pose an unacceptable risk; and
7
-------
b. Restore groundwater to its anticipated beneficial use as a drinking water aquifer in a
reasonable timeframe.
It is important to note that the original Site decision documents (1989 ROD, 1992 ROD Amendment,
and subsequent ESDs) did not specify different Site OUs. Instead, OU designations (described in the
Status of Implementation section below) were developed during the remedial design/remedial action
phase to manage implementation of the remedy at the Site. The 2022 ROD Amendment is the first
decision document to explicitly designate OUs.
The selected remedy for this Site in the 1989 ROD, as revised by the 1992 ROD Amendment and the
four subsequent ESDs, includes the remedy components described below.
a. Excavation of contaminated sediments and soils in defined wetland areas to achieve cumulative
risk-based (i.e. >1 x 10"6 cancer risk, >1.0 hazard index chronic noncancer risk, or >1.0
subchronic risk index) soil/sediment cleanup action levels (CALs) for sampling areas with
contaminants identified above background, and consolidation on the Site property;
b. Construction, operation and maintenance (O&M), and monitoring of a groundwater pump-and-
treat system to contain contaminated groundwater and achieve risk-based GWCALs;
c. Construction, O&M, and monitoring of a deep underground injection well at the Site property
for disposal of the contaminated groundwater following treatment;
d. Construction of a groundwater barrier wall around the Site source area and pumping
groundwater within the barrier wall to lower the water table;
e. Treatment of contaminated soil within the groundwater barrier wall by soil vapor extraction
(SVE) to achieve at least a 97% reduction in VOCs;
f. Excavation or solidification/stabilization (S/S) of the soil most highly contaminated by metals
and cyanide (risk index >50);
g. Construction of a final cover over soil and sediments left on-Site;
h. Implementation of access restrictions and deed restrictions; and
i. Long-term monitoring of the final cover, groundwater remedy, vertical barrier wall, and
institutional and engineering controls (e.g. deed restrictions and perimeter fencing).
The 2022 ROD Amendment includes the following fundamental change to the remedy for OU1,
groundwater remedy.
j. The selection of monitored natural attenuation (MNA) to replace pump-and-treat to address
the remaining groundwater contamination.
The 2022 ROD Amendment also includes the following significant change to the remedy for OU1.
k. The selection of new cleanup standards for the groundwater COCs, changing from sample-
specific GWCALs to parameter-specific cleanup levels (CLs) (see Table 1 below).

Notes
1 - The selected groundwater cleanup levels (CLs) are the maximum contaminant level (MCL) per the federal Primary
Drinking Water Standards. If no MCL has been established, then the Indiana Remedial Cleanup Guide for the
Groundwater Residential Tap pathway limit per the March 2022 Table A-6 is used, and noted as Table A-61 in the
Source column.
2 - If a background value from the 1992 Consent Decree and associated Scope of Work is greater than the MCL or the
Table A-6 value, then that background value is used as the CL and noted as 'Bkgd' in the Source column. Note that the
only such value is for Chromium (VI) at MIDCO 1.
AKA - 'Also know as1, which provides an alternate common name for select contaminants for clarity.
CAS - Chemical Abstracts Service unique identification number, which has been provided for select contaminants for
clarity.
This table has been prepared by EPA Region 5 Superfund & Emergency Management Division for Record of Decision
Amendment, MIDCO 1 and MIDCO II Superfund Sites, September 2022.
An updated list of Site-specific background constituents was finalized in a statistical analysis completed
in 2012 (Arcadis, 2012). The purpose of this analysis was to identify background-related inorganic
11
-------
constituents detected in Site groundwater during five annual monitoring events (2005 to 2011). Based
on this document and the 2015 ESD, the following constituents were excluded from well-by-well
cumulative risk calculations at the MIDCO I Site: arsenic, barium, cadmium, chromium, manganese,
mercury, thallium, vanadium, and iron. The 2015 ESD also added 1,4-Dioxane (1,4D) as a COC at the
Site.
Status of Implementation
EPA, the State of Indiana, and a number of Settling Defendants entered into a 1992 Consent Decree
(CD) for the design and implementation of the selected remedy at the Site. The CD included a
Statement of Work (SOW) that described the work to be completed. The Settling Defendants formed
the MIDCO Remedial Corporation (MRC) to complete the required remedial actions.
The remedial action work as decided in the 1989 ROD, 1992 ROD Amendment, four following ESDs at
the Site are complete as summarized in the Remedial Action Report, Revision 1 (AECOM, 2017). A brief
chronology summarizing implementation of the various remedy components is below, followed by a
more detailed description of remedy implementation organized by OU.
• Wetland mitigation settlements in 1993;
• interim sediment removal operations in 1993;
• construction of the groundwater extraction and treatment system (GWETS) from 1992-1996,
with startup of the system in 1997;
• installation of a groundwater barrier wall (bentonite slurry wall) surrounding the source area in
late 2003;
• construction of the SVE system in 2005-2006, with startup and operation of the SVE system in
2006 and completion in 2010 after achieving 97% reduction in baseline organic vapors;
• continued operation of the SVE system from 2010 to 2013 - this was performed on a voluntary
basis by the MRC to further reduce organic vapors within the barrier wall prior to final remedial
construction activities;
• shutdown of the GWETS in 2010 to allow for an evaluation of MNA;
• from 2014 to 2016, installation of groundwater collection piping within the barrier wall, soil
stabilization treatment in place of soil excavation, sediment cap construction and final cover
construction; and
• from 2022 until present day, MNA to achieve groundwater CLs.
The remedial action work included within each OU at the Site is described below.
OU1 - Groundwater Extraction, Treatment and Deep Well Injection
The groundwater extraction, treatment, and deep underground well injection system was constructed
during 1992-1996, in accordance with the Final Design Package, Ground Water Remediation System,
Final Design Report (ERM, 1994) and began operation in 1997. In 2001, MRC constructed an expansion
to the pump-and-treat system to improve groundwater capture at the Site. After the Site groundwater
was treated via combined hydrogen peroxide and ultraviolet radiation followed by air stripping to meet
the maximum allowable concentrations (MACs) for deep-well injection, it was combined with the
treated groundwater from MIDCO II (which arrived at this Site via an underground pipeline), and
12
-------
pumped to the deep injection well located on property adjacent to this Site. Continuous operation of
the GWETS occurred from 1997 to 2010 when it was temporarily shut down to allow MRC to conduct
an MNA evaluation for groundwater. MRC submitted a report, titled Monitored Natural Attenuation
Groundwater Remedy Demonstration, MIDCO I and II, Gary, Indiana (AECOM, 2018), for EPA review
that described the lines of evidence and other Site characteristics that indicated MNA is a feasible
remedy at the Site. In 2022, EPA issued a ROD Amendment to select MNA as the final remedy to treat
groundwater contamination at the Site. Currently, EPA and MRC are negotiating modifications to the
SOW in the 1992 CD, which will finalize the framework by which MNA will be conducted and
completed.
OU2 - Soil and Sediment Treatment and Excavation
During 2002-2003, MRC designed the vertical groundwater barrier wall around the source area soils to
a depth of approximately 33 feet and with a hydraulic conductivity of lxlO"7 centimeters per second
(cm/s). In late 2003, MRC constructed the barrier wall and started dewatering within the barrier wall to
improve barrier wall and future SVE function. During 2003-2005, MRC designed the SVE system. MRC
constructed the SVE system during 2005-2006, and the system began operation in March 2006.
Although SVE achieved performance standards (>97% reduction in baseline organic vapors) in 2010,
MRC continued to operate the system voluntarily until its shutdown in May 2013. Vapors collected by
the SVE system were destroyed by a thermal oxidation system.
In addition to construction activities that addressed soil, interim sediment excavation activities were
completed in 1993. The excavated sediments were placed under the interim cover of the Site source
area. Residual sediment risk assessments were completed in 2011 and updated in 2014 to determine
whether any additional actions were necessary in the excavated sediment areas. EPA subsequently
determined that the excavated sediment areas required a soil cover. The required soil cover was
implemented as part of OU3 (see below).
Following SVE treatment, the 2004 ESD and Section V.C.2 of the 1992 ROD Amendment selected a soil
S/S remedy to replace the excavation and off-site disposal of source area soils contaminated with
metals and cyanide (EPA, 2004). The revised soil remedy addressed areas where the groundwater risk
factor criterion for metals and cyanide was greater than 50, as defined in the 2004 ESD. In September
2014, pre-treatment of specific soil grids was completed using in-situ chemical oxidation to treat and
substantially reduce leachate concentrations for cyanide prior to soil S/S treatments. AECOM
completed the final in-situ soil S/S treatment using Portland cement in November 2014. Following
completion of the soil S/S activities, leachate concentrations for metals and cyanide were significantly
below the 2004 ESD groundwater risk factor criterion of 50, indicating the soil S/S treatment activities
were successful. The Remedial Action Report for OU2 was submitted by AECOM and approved by EPA
in 2017.
OU3 - Final Site Cover
The Site final cover was installed over the portion of the Site identified in the SOW and the MIDCO I
Site Closure Plan (ARCADIS, 2011). The final cover extends slightly beyond the barrier wall to the limits
of the former MIDCO I facility fence line, which encompasses an area of 3.9 acres. The final cover
13
-------
minimizes the infiltration of precipitation through the soil and serves as a direct contact barrier to
human and animal exposure pathways. In January 2016, AECOM completed construction of the soil
cover over contaminated sediment areas as part of the final Site cover, in accordance with the final
design plans and Construction Quality Assurance Plan. The final vegetation was successfully established
based on an assessment conducted in early November 2016. The final site cover construction was
completed as documented in the 2017 remedial action report (AECOM, 2017). The final cover consists
of the following layers, from top to bottom:
• Minimum 24" soil protective layer comprised of topsoil to promote vegetative growth and a
minimum 18" compacted clay protective layer;
• Double-sided geocomposite drainage layer; and
• 40-mil high-density polyethylene geomembrane.

Status of Access Restrictions and ICs:
Along with the Site fencing to restrict access as described above, deed restrictions were implemented
in 1993 for properties within the final cover area per the 1989 ROD and the 1992 ROD Amendment.
The 1992 and 1993 deed restrictions include one or more of the following elements:
• No consumptive or other use of the groundwater underlying the Property that could cause
exposure of humans or animals to the contaminated groundwater underlying the Property.
• No residential, commercial, or agricultural use of the Property, including but not limited to, the
construction, installation or use of any structures or buildings for residential, commercial, or
agricultural purposes.
• No installation, removal, construction, or use of any buildings, wells, pipes, roads, ditches or
any other structures at the Property, except as approved by EPA.
• No tampering with, or removal of, any containment or monitoring systems or remedial action
work on the Property.
• No interference with the performance of work and remedial action, or with the maintenance of
remedial measures approved by EPA and/or the United States District Court for the Northern
District of Indiana.
• After the final approval by EPA of the completion of all remedial action work and achievement
of all cleanup and performance standards at the MIDCO I Facility, all uses of the Property shall
be consistent with the final remedial action implemented at the MIDCO I Facility.
Access agreements were obtained for the initially planned Site remedy in 1993. The completed final
cover required access agreements for additional properties (see below for explanation). Deed
restrictions were pursued for these parcels with the owners. In general, the access restrictions included
the following provisions:
• The Authorized Persons shall have an irrevocable right of access upon the Property for the
purpose of performing or monitoring performance of response actions until such time as
cleanup and monitoring and maintenance activities have been completed at the Property.
• The Authorized Persons shall have the right to enter upon the Property to implement the
remedial action selected by USEPA and take such response action as USEPA deems necessary.
15
-------
• The Authorized Persons shall have the right to enter upon the Property to take samples from
the soil, groundwater, and surface water as needed in furtherance of the remedial action.
• All tools, equipment, buildings, improvements and other property taken upon or placed upon
the Property by or at the direction of the Authorized Persons shall remain the property of the
Authorized Persons.
• The Authorized Persons shall have the right to patrol and police the Property during the period
in which this irrevocable right of access is in effect.
• The parties hereto agree that this irrevocable right of access does not constitute a release of
any claims.
Deed restrictions and access agreements were recorded with Lake County, Indiana in 1992 and 1993,
and are included in Appendix A of the approved Institutional Controls Implementation and Assurance
Plan (ICIAP) for the Site (AECOM 2017).
The original Site remedy described in the 1989 ROD did not require deed restrictions for parcels
occupied by the contaminated sediment area, as full excavation was considered feasible at that time.
EPA issued the March 2015 ESD to significantly change the sediment remedy to a sediment cover with
ICs in the north and east portions of the Site. Deed restrictions, access agreements, and/or deed
notices were recorded for all parcels with sediment covers in 2020 as described in Appendix E. The
majority of these deed restrictions and access agreements were recorded with Lake County, Indiana in
2020 in a form acceptable to EPA and IDEM and in compliance with the CD. Deed notices were
recorded in 2020 for all properties with remedy components where deed restrictions and access
agreements could not be placed due to lack of property owner identification or agreement to the
proposed terms. It should be noted that parcels at MIDCO I with remedy components and only deed
notices are not recommended to be part of NPL deletions until deed restrictions and access
agreements are recorded. The best efforts of the MRC and Settling Defendants to implement and
secure future deed restrictions will be documented in the ICIAP annual report.
Finally, the City of Gary Ordinance No. 7930 was enacted in 2006, which restricts groundwater usage
within the municipality. The ordinance was signed into law on July 3, 2006 to limit exposure to and
consumption of potentially contaminated groundwater from the shallow unconsolidated groundwater
within the municipality. The ordinance prohibited drilling of new potable water supply wells in the
unconsolidated aquifer within the municipality. The ordinance also required all existing potable well
users to connect to the municipal water (derived from Lake Michigan) within one year of the
ordinance. If connection to the municipal water supply was not possible, feasible or impracticable,
users must draw water from the deeper confined aquifer. No potable water wells are located at the
Site and EPA is not aware of any non-compliance of the City of Gary Ordinance prohibiting potable
water use from the unconfined aquifer surrounding the Site and throughout the municipality.
Current Compliance:
The final Site remedy engineering controls include: the final cover and barrier wall, sediment cap, and
perimeter fencing. Site remedy inspections performed by AECOM at the Site on June 20, 2022, and
December 14, 2022, confirmed that the integrity of the final cover and sediment cover areas,
groundwater monitoring wells, perimeter fencing, and stormwater management facilities remain intact
16
-------
and undamaged (AECOM, 2023). The FYR Site inspection performed by EPA on November 9, 2023, also
confirmed these engineering controls remain intact, undamaged, and effective. The Site remains
undeveloped except for the remedial features described herein. Thus, there are no known IC
compliance issues at the Site.
IC Follow up Actions Needed:
Although most parcels at MIDCO I have deed restrictions and access agreements, there are several
parcels that only have CERCLA 120(h) deed notices that inform the owner of the Site's history and
contamination, but do not restrict activities that would interfere with the remedy's performance. The
reason deed restrictions are not in place is due to an inability to identify or contact the current
property owner. A list of parcels that only have CERCLA 120(h) deed notices can be found in Table 1 of
the Annual Institutional Control Report (AECOM 2023 and Appendix E). The deed notices and other
site-wide ICs (i.e. Gary Ordinance and perimeter fencing) are sufficient to ensure the remedy's
protectiveness, unless new information changes that determination.
New monitoring wells are necessary to conduct MNA. ICs such as access agreements and deed
restrictions may be needed if these new monitoring wells are installed on properties lacking access
agreements and deed restrictions.
The 1,4D plume area may be migrating or increasing in size beyond previously understood limits given
the recent 1,4D detection above the cleanup level on the eastern, sidegradient edge of the
groundwater plume as presented further below. Pending the collection of additional groundwater data
to evaluate such possible expansion, the ICIAP should be updated to include procedures for periodic
reviews of governmental controls to confirm compliance of nearby properties with the municipal
groundwater ordinance and to ensure that there are not any new exposure routes to affected areas of
the unconsolidated aquifer.
Long Term Stewardship:
Long-term stewardship procedures are in place as part of the Site ICIAP (AECOM, 2017) and require
annual evaluation of the ICs, based on semi-annual and annual inspection findings. The IC evaluation is
to assess: (i) whether Site remedy engineering controls remain intact and undamaged, (ii) whether the
use of the Site has conformed to recorded deed restrictions, and (iii) whether potential IC deficiencies
exist. In addition, the evaluation is to assess whether recorded land use restrictions no longer apply
and may be terminated, if feasible. Any changes to ICs will be documented.
Current parcel ownership, owner contact information, and title commitments will be verified by
Chicago Title Insurance Company or an equivalent agency. American Land Trust Association title
commitment documentation will be obtained every five years prior to EPA's FYR for the Site. In the
event of transfer of ownership, deed restrictions recorded at the Registry of Deeds will be identified
during the title search conducted by new owners prior to the transfer of the property. In the event of a
property rental, it is the owner's responsibility to ensure that the tenant is informed of the recorded
ICs.
During 2022, AECOM confirmed the ICs at the MIDCO I parcels were in conformance with recorded
deed restrictions, absent of IC deficiencies, and absent of a need for IC modification or termination.
17
-------
MIDCO I property ownership was reviewed in 2022; no parcels changed ownership between 2021 and
2022. The ten parcels have deed restrictions recorded with Lake County, Indiana. American Land Trust
Association title commitment documentation was acquired for the Site's parcels to confirm any Site-
related deed restrictions remain connected to their respective parcels.
Systems Operations/Operation & Maintenance
O&M activities continue to take place at the Site. O&M of the Site fence and final soil cover is
performed on a yearly basis, and the records are available at the office of the MRC's current
contractor, Ramboll. The groundwater pump-and-treat, SVE, and thermal oxidation systems have all
been shut down, so active O&M of these remedy components is currently not required. O&M is
required for Site components (wells, piezometers, etc.) necessary to implement MNA and required
changes will be described in detail and added to the Site's O&M records following CD negotiations
between MRC and EPA. No other changes related to O&M since the last FYR have occurred at the Site.
III. PROGRESS SINCE THE LAST REVIEW
This section includes the protectiveness determinations and statements from the last FYR as well as
the recommendations from the last FYR and the status of those recommendations.
Table 3: Protectiveness Determinations/Statements from the 2019 FYR
ou#
Protectiveness
Determination
Protectiveness Statement
1
Short-term Protective
The remedy at OU #1 currently protects human health
and the environment because the groundwater pump-
and-treat system operated until it reached its maximum
effectiveness, and deed restrictions on some properties
and a City of Gary ordinance prohibit residential usage
of groundwater and serve to prevent exposure to the
remaining groundwater contamination at the Site. In
order for the remedy to be protective in the long term,
the following actions need to be taken to ensure
protectiveness: GWCAL waiver or modification of non
MIDCO 1 site related constituents for iron, manganese,
and pentachlorophenol; evaluate monitored natural
attenuation to address low-level residual constituents in
groundwater. Currently, there is a city ordinance in
place preventing groundwater use.
2
Short-term Protective
The remedy at OU #2 currently protects human health
and the environment because the remedial activities
completed have adequately addressed all exposure
pathways that could result in unacceptable risks to soil
and sediment. These remedial activities included
operation of the SVE system which was successful in
achieving a 97% reduction of VOCs in the subsurface soil
within the barrier wall, excavation of contaminated
sediments and placement under a cap, excavation
and/or in-situ treatment of contaminated soils, and
18
-------
placed a soil cover over previously excavated areas
containing residual sediment concentrations. However,
in order for the remedy to be protective in the long
term, the following actions need to be taken to ensure
protectiveness: additional ICs are being pursued for
areas with constructed remedy components that were
not contemplated or identified in the 1989 ROD, 1992
ROD Amendment, and subsequent ESDs but were
added later.
3
Short-term Protective
The remedy at OU #3 currently protects human health
and the environment because the remedial activities
completed have adequately addressed all exposure
pathways that could result in unacceptable risks to the
areas of the Site covered by the final soil cap. These
remedial activities included fencing, deed restrictions,
and completion of the final multilayer soil cap to
prevent contact with contaminated soils and sediment,
including placing a soil cover over previously excavated
areas containing residual sediment concentrations.
However, in order for the remedy to be protective in
the long term, the following actions need to be taken to
ensure protectiveness: additional ICs are being pursued
for areas with constructed remedy components that
were not contemplated or identified in the 1989 ROD,
1992 ROD Amendment, and subsequent ESDs but were
added later.
Sitewide
Short-term Protective
The remedy at the MIDCO 1 Site currently protects
human health and the environment because the
remedial activities completed at the Site have
adequately addressed all exposure pathways that could
result in unacceptable risks. These remedial activities
included the following: operation of the groundwater
pump-and-treat system until it reached its maximum
effectiveness; operation of the SVE system to achieve a
97% reduction in VOCs in the subsurface; excavation of
contaminated sediments and placement under a cap;
excavation and/or in-situ treatment of contaminated
soils; completion of a final multi-layer soil cap to
prevent contact with contaminated soils and sediment,
including placing a soil cover over previously excavated
areas containing residual sediment concentrations;
fencing to restrict access to the Site; and
implementation of ICs including deed restrictions and a
City of Gary ordinance. However, in order for the
remedy to be protective in the long term, the following
actions need to be taken to ensure protectiveness:
GWCAL waiver or modification of non MIDCO 1 Site
related constituents for iron, manganese, and
pentachlorophenol; evaluate monitored natural
19

attenuation to address low-level residual constituents in
groundwater; additional ICs are being pursued for areas

IV. FIVE-YEAR REVIEW PROCESS
Community Notification. Involvement & Site Interviews
A public notice was made available by a newspaper posting in the Post-Tribune of northwest Indiana
on 12/27/2023 and online at https://www.epa.gov/in/epa-begins-sixth-five-vear-review-midco-i-
superfund-site on 8/31/2023, stating that there was a FYR and inviting the public to submit any
comments to EPA by 4/1/2024. No comments were received. The results of the review and the report
20
-------
will be made available at the Site information repository located at the Site's online webpage
https://www.epa.gov/superfund/midco-i and U.S. EPA Region 5 Library, 16th Floor, 77 W. Jackson
Blvd., Chicago, IL 60604, open Monday - Friday, 8:30 a.m. to 3:00 p.m.
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.
EPA interviewed the AECOM project manager for the Site to discuss their concerns, community
engagement, and recommendations at the Site. One concern they raised is flooding and area-wide
stormwater drainage and routing issues due to 20-40 foot piles of debris at the eastward neighboring
property where Gary Material Supply conducts operations. In 2020, representatives from Gary
Material Supply, EPA, and IDEM convened to develop a solution to the flooding and drainage issues
and review planning documents. To AECOM's knowledge, however, Gary Material Supply has taken no
actions to resolve the flooding and drainage issues. Thus, the AECOM project manager recommended
EPA reconnect with Gary Material Supply and/or the appropriate IDEM representative to discuss
progress on the drainage issue. Flooding and poor drainage at the Site have prevented sampling of
wells that would help delineate Site groundwater contaminants and assess whether MNA is meeting
RAOs. EPA agrees that the flooding and drainage issue identified by the AECOM project manager poses
a long-term threat to the Site remedy's protectiveness for OU1. Thus, EPA recommends Gary Material
Supply, or the relevant IDEM staff member, is contacted to finalize plans that resolve the flooding and
drainage issues at the Site and surrounding area.
EPA sent a brief Site summary to City of Gary, Indiana and proposed a virtual interview to discuss the
current Site status and possible successes, problems, or unusual situations at the Site. However, EPA
did not receive a reply to this communication.
Data Review
EPA's OU1 data review draws from several recent reports provided by AECOM/Ramboll and approved
by EPA including, but not limited to, the 2022 Annual Groundwater Monitoring Report (Ram bo 11
Environ, 2023), the 2023 Annual Groundwater Monitoring Report (Ramboll Environ, 2023), and the
2018 MNA Demonstration (AECOM, 2018). All groundwater contamination and monitoring wells are in
the unconsolidated upper aquifer, the Calumet Aquifer, of Gary, Indiana.
Groundwater Results Within the Containment Barrier Wall
It was demonstrated as part of the 2013 Groundwater Remedy Pre-Final Report that any potential
leakage through the barrier wall under conservative hydraulic conditions would be insignificant
(AECOM, 2013). The mean hydraulic head (601.32 ft) on the upgradient side (MW-4S) of the barrier
wall was observed to be 0.49 feet higher than the mean groundwater elevation within the barrier wall
from 2019 to 2022. The mean hydraulic head of shallow wells within the barrier wall (600.83 ft) was
1.06 ft higher than the mean hydraulic head (599.78 ft) immediately downgradient of the barrier wall
from 2019-2022. The average distance between the barrier wall and the nearest downgradient
monitoring wells is about 119 ft, giving a mean hydraulic gradient of 0.009 ft/ft. In a conservative case
where transient water levels within the barrier wall are up to two feet higher than downgradient
groundwater level outside the wall (creating a localized outward gradient), groundwater passing
21
-------
through the barrier wall would contribute only 0.3% to the total volume of groundwater flowing
around the wall and downgradient. Currently, groundwater levels within the barrier wall indicate that
the barrier wall is performing within expectations.
According to the 2022 and 2023 Annual Monitoring Reports by Ramboll, wells within the containment
barrier wall exhibited groundwater CL exceedances for at least one of the following COCs: vinyl
chloride, 1,2-dichloroethane, benzene, ethyl benzene, toluene, xylenes, and 1,4D. This is similar to
exceedances in the 2017 Annual Monitoring Report, which was used to assess Site protectiveness in
the 2019 FYR (Ramboll Environ, 2018).
The concentrations of benzene, toluene, ethylbenzene, and xylenes (BTEX) within the barrier wall have
increased in wells MW-5S and MW-6S since pump and treat shutdown in 2010. Specifically, the
concentration of total BTEX increased from 3.2 |ag/L to 118 |ag/L in M W-5S and from 47 |ag/L to 103.5
Hg/L in MW-6S between 2012 and 2022. In one deep well, MW-5D, vinyl chloride and cis-1,2-
dichloroethene were previously undetectable in 2012 but have since increased to 3.4 and 11 |ag/L
respectively. The same wells within the barrier wall with steady increases in COC concentrations also
have increasing 1,4D concentrations. For example, 1,4D concentrations in well MW-6S increased from
87 |ag/L to 310 |ag/L and in well MW-6D increased from 32 |ag/L to 95 |ag/L between 2012 and 2022.
The 2023 groundwater monitoring results from within the barrier wall agree with these observed
trends.
These steady increases in multiple wells within the barrier are unlikely to be caused by sporadic
contaminant movement but may be caused by back diffusion from low permeability clay and silt
geologic formations, such as the silty clay floor of the unconsolidated Calumet aquifer. The increasing
concentrations of COCs do not pose a threat to human health or the environment because they are
within the barrier wall and the barrier wall remains effective, but they indicate that MNA within the
containment barrier wall may take longer than the 25 years estimated in the 2022 ROD Amendment.
For this reason, groundwater contaminant dispersion and trend modeling should be conducted to
generate an updated estimated time to achieve groundwater CLs within the barrier wall.
Groundwater Results Outside of the Containment Barrier Wall
The only COCs with CL exceedances outside the barrier wall are 1,4D and PCP. In general, the 1,4D
concentrations at wells with CL exceedances outside of the containment barrier have remained stable
or decreased over time.
Previously, the highest concentration of 1,4D outside the barrier wall has been consistently observed in
deep well H-30 (83 |ag/L in 2022 and 70 |ag/L in 2023), which is located approximately 400 feet
northeast of the barrier wall. Downgradient wells northeast of H-30 have historically remained below
CLs indicating limited contaminant migration northeast of the barrier wall.
As recently identified in sampling performed in 2023, deep well O-30 located approximately 250 feet
east of the containment barrier wall and sidegradient of the center of the 1-4D groundwater plume,
contained the highest 1,4D concentration (120 |ag/L) outside the barrier wall during the 2023 sampling
event. Well O-30 had been inaccessible in recent years due to flooding. Other wells nearby or
downgradient of O-30, including, N-10 and N-30, have remained flooded and were not able to be
22
-------
sampled in 2023 to determine the eastern extent of 1-4D above CLs in this area. For the estimated area
where 1,4D exceeds CLs in the shallow and deep portions of the unconsolidated aquifer see Figures 3
and 4, respectively. For a table with 1,4D concentrations over time see Table 5-6 in the 2023 Annual
Monitoring Report (Ramboll Environ, 2024).
While further data collection is necessary to confirm the current 1,4D plume size per the recent 1,4D
exceedance at sidegradient well O-30, no known exposures exist to the unconsolidated aquifer. The
City of Gary Ordinance No. 7930 prohibits use of the contaminated, unconsolidated aquifer within the
municipal limits. Potable water is either obtained from for the municipality (derived from Lake
Michigan) or is to be obtained from a deeper, confined aquifer. The unconsolidated aquifer is not used
at the Site and EPA is not aware of non-compliance of the ordinance at nearby downgradient
properties or elsewhere within the municipality. Moreover, EPA reviewed historical documents for the
Site and notes that as of 1989 there was only one private well downgradient of the current 1,4-dioxane
plume and this well was over 1 mile away from the Site. Finally, given the location of well O-30 nearly
four miles from the closest downgradient municipal boundary and the concentration of 1,4D detected
in the monitoring well network, there is no expectation that 1,4D from the Site would be present
above CLs in areas beyond where the municipal ordinance is in effect. As such, the remedy remains
protective.
Further investigation is needed on the east portion of the 1-4D plume at and surrounding well O-30 to
evaluate the eastern extent of the 1-4D plume. The cause of the flooding in this area should be
addressed to allow for sampling the currently inaccessible wells in the vicinity of well O-30, otherwise
new monitoring wells will need to be installed to obtain the required data. Updates to the ICIAP are
also recommended to confirm continued compliance of nearby properties with the municipal
ordinance prohibiting the use of the unconsolidated aquifer for potable use.
The other COC above CLs outside of the containment barrier wall is PCP at MW-4S located immediately
west of the barrier wall along the western property line. This well is generally upgradient of the Site.
This pesticide was historically observed in well MW-4S from 2010-2012 at concentrations ranging from
810 to 1,900 |-ig/L. In 2013 the pesticide was measured at 12 |ag/L and remained at low concentrations
until 2021 when it was again observed at an elevated concentration (720 |ag/L) before dropping again
in 2023 (12 |-ig/L). Wooden utility poles, particularly those produced in the mid to late 20th century,
were commonly treated with PCP to prevent damage from fungus and insects. This sporadic release
could be caused by one of two wooden utility poles that are located nearby well MW-4S. Further
investigation is warranted to confirm the source of the detections at MW-4S. If an off-site source is
confirmed, the COCs requiring further monitoring should be updated accordingly.
Site Inspection
The inspection of the Site was conducted on 11/9/2023. In attendance were Jeffrey Dewey of EPA,
Stephanie Andrews of IDEM, Matthew Lefauve of EPA, Amy Gahala of the United States Geological
Survey, Karen Chen of EPA, and Tat Ebihara of AECOM. The purpose of the inspection was to assess the
protectiveness of the remedy.
The inspection found that OU2 and OU3 remedies, including but not limited to implemented ICs, the
fencing and the soil cap, are well maintained and operating as intended by the site decision
23
-------
documents. Furthermore, Site conditions have not changed since the 2019 FYR that would indicate
these remedies are not protecting human health or the environment.
For OU1, the inspection found the current physical components of the groundwater remedy (i.e.
monitoring wells and piezometers) are, for the most part, well maintained and operating as intended
by the site decision documents. However, some issues were noted at the Site that may impact the
Site's future protectiveness. One issue during the inspection was inaccessibility of wells 0-10/0-30, G-
10/G-30, and N-10/N-30 due to phragmites overgrowth, flooding, and unsafe conditions respectively.
Following the inspection, AECOM and Ramboll attempted to access these wells and were able to reach
0-10/0-30, but not the others. G-10/G-30 and N-10/N-30 are important for delineating the
northeastern and eastern extent of 1,4D in deep groundwater and confirming the Site's groundwater
flow direction. These wells need to be accessed and repaired or replaced to accurately assess the
performance and protectiveness of the groundwater remedy by or before September 2025.
Another observed issue that could impact the ability of the current Site remedy to achieve CL for PCP
was locating two utility poles near well MW-4S that may be an off-site source of PCP. Specifically, EPA's
ecological risk assessor, Matthew Lefauve, examined each pole and noticed a dark coating on one that
may be PCP. If one or both utility poles are the offsite source of PCP at the Site, then modification to
COC listing for PCP should be considered.
Several other minor issues were identified with OU1 during the inspection, but these do not impact the
Site's current or future protectiveness. These included two wells, MW-3S and B-10, that have loose
internal PVC piping that indicates the well's seal may be compromised. These two wells should be
assessed for repair or abandonment, if determined not needed, following discussions between EPA,
State, and MRC. Another issue was the inconvenient accessibility of monitoring wells due to locks with
multiple lock and key systems. One well's lock had evidence that a bolt cutter was used to try and gain
access to the well. The Ramboll team did not encounter issues that prevented them from acquiring a
groundwater sample at any well during the 2023 annual groundwater sampling event (report pending).
Thus, addressing this issue with a single new locking system does not impact the Site's current or
future protectiveness, but could improve the Site remedy's efficiency.
V. TECHNICAL ASSESSMENT
QUESTION A: Is the remedy functioning as intended by the decision documents?
Question A Summary:
Yes. The majority of remedy components are functioning as intended by the decision documents.
However, additional data and analysis is required to ensure the MNA groundwater remedy is
functioning as intended by the decision documents. A summary of which Site components are and may
not be functioning as intended is presented below.
Groundwater pump-and-treat system and deep well injection system (OU1): The pump-and-treat
system was shut down in September 2010 because it had reached its maximum effectiveness. The
pump-and-treat and deep well injection systems operated in compliance with all air emission and
underground injection well requirements and achieved adequate groundwater capture while in
24
-------
operation. The data indicated that VOCs and other contaminants in groundwater outside of the barrier
wall were being remediated. The new groundwater remedy was decided to be MNA in the 2022 ROD
Amendment.
Groundwater monitored natural attenuation (OU1): MNA was piloted starting in 2010 and was selected
as the final remedy to address groundwater contamination by a 2022 ROD Amendment. However,
MNA may not be performing as expected with contaminant concentrations increasing significantly in
several monitoring wells within the barrier wall, and contaminant concentrations decreasing at a
slower rate than initially calculated (see the Data Review subsection). Furthermore, 1,4D was detected
at the eastern-most monitoring well at the Site (O-30). These unexpected results indicate additional
monitoring wells towards the eastern portion of the Site are required to delineate the 1,4D plume. The
results also may indicate MNA will take a significantly longer time to achieve cleanup goals than
anticipated. EPA has provided a recommendation (i.e. - groundwater sampling, monitoring well
installation, updated data analyses, groundwater modeling, and estimated cleanup timeframe) to
address these concerns and ensure the Site remains protective in the future and achieves RAOs.
Soil and sediment excavation (OU2): There have been no changes in the soil and sediment excavation
remedy or Site conditions since the previous FYR. Access controls, the Site fence, remain well
maintained and effective. Thus, the remedy continues to function as intended by the decision
documents.
Final soil cap (OU3): The final cover continues to minimize the infiltration of precipitation through the
soil and acts as a direct contact barrier to prevent human exposure and/or animal exposure. The
routine cap inspections and EPA's FYR Site inspection confirmed there were no changes in the remedy
or Site conditions since the last FYR that would indicate the final soil cap is not effective. Thus, the final
soil cap continues to function as intended by Site decision documents.
Access controls (OUs 1, 2, and 3): The Site fence currently protects public health exposure to
contaminated soil and sediments and protects constructed remedy components. Routine inspections
and EPA's FYR inspection confirmed there have been no changes in the implemented remedy or Site
conditions since the previous FYR that indicate access controls are not effective. Thus, the access
controls continue to function as intended by Site decision documents.
Institutional Controls: ICs in the form of deed restrictions, access agreements, and deed notices are in
place and effective as required by the decision documents. ICs are identified and documented in the
ICIAP for the Site. Specifically, deed restrictions were recorded with Lake County, Indiana in 1992,
1993, and 2020, and access agreements and deed notices were completed in 2020. Additional deed
restrictions are recommended for the several properties that have CERCLA 120(h) deed notices. Long-
term stewardship procedures are in place as part of the ICIAP, and require annual evaluation of the ICs,
based on semi-annual and annual inspection findings. With that said, to ensure there are no future
exposure routes to groundwater contamination of the unconsolidated aquifer, the ICIAP requires an
update to include procedures for periodic reviews of governmental controls to confirm compliance of
nearby properties with the municipal groundwater ordinance. Finally, additional monitoring wells will
be added to implement MNA and so future ICs should be considered if wells are placed on properties
lacking sufficient ICs.

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. The toxicity data and cleanup levels are not still valid, and there have been changes in the physical
conditions at the Site that would affect the protectiveness of the remedy. This is due to a new rule,
recently finalized by EPA, that acknowledges new toxicity data and changes standards in a way that
may affect the Site remedy.
Changes in Exposure Pathways
PFAS may represent a newly identified contaminant that may pose a risk to human health or the
environment via Site groundwater. These contaminants are commonly found in numerous hazardous
and non-hazardous wastes since the 1950s including chemical manufacturing wastes and aqueous film
forming foam (AFFF). There may be PFOA and PFOS contamination at the Site given hazardous
chemical wastes were stored and released and a large chemical fire took place at the Site, which may
have been extinguished using AFFF. Sampling for PFAS is required to determine if it is present and site-
related and to ensure the Site remedy remains protective of human health and the environment.
However, the Site's past remedy, groundwater extraction and treatment system, along with
groundwater containment measures (i.e. barrier wall) likely mitigate/mitigated the risk posed by PFAS
if discovered at the Site. Moreover, there is no known exposure pathway to drinking water due to the
Gary City Ordinance from 2006 that required all private well users to connect to Gary City water within
one year of the Ordinance or, if technically infeasible, draw water from the deeper confined aquifer,
further preventing the potential human health exposure scenarios posed by contaminated
groundwater released from the Site.
Expected Progress Towards Meeting RAOs
The Site is on track to eventually meet RAOs. However, the timeframe to meet RAOs may be longer
than the 25-year estimate provided in the 2022 ROD Amendment. Data regarding eastward 1,4D
plume delineation, adsorbed 1,4D mass in the upper aquifer clay bed, and analysis of potential PFOA
and PFOS concentrations in groundwater are required to accurately recalculate this timeframe.
QUESTION C: Has any other information come to light that could call into question the protectiveness
of the remedy?
No. No other information has come to light that could call into question the current protectiveness of
the remedy. However, the Site has not been evaluated for possible impacts of climate change and
natural disasters. The midwestern area of the United States is expected to see increases in rainfall due
to climate change. This may result in increased flooding at the Site that theoretically could in turn
impact Site remedy components such as monitoring wells.

OTHER FINDINGS
In addition, the following are recommendations that were identified during the FYR that may improve
performance of the remedy, reduce costs, or accelerate Site close out, but do not affect current nor
future protectiveness:
Several parcels at the Site have deed notices, but do not have deed restrictions despite containing
waste that prevents UU/UE and/or remedy components. Thus, it is recommended that deed
restrictions are acquired for all properties where waste remains above UU/UE or remedy components
are present that currently have only deed notices.
The lock and key system for monitoring wells at the Site is inefficient and should be replaced with a
single lock and key system for all wells and remedy components as appropriate.
Two wells, MW-3S and B-10, that have loose internal PVC piping that indicates the well's seal may be
compromised. These two wells should be assessed for repair or abandonment, if determined not
needed, following discussions between EPA, State, and MRC.
VII. PROTECTIVENESS STATEMENT
29
-------
Protectiveness Statement(s)
Operable Unit: OU1 Protectiveness Determination:
Short-term Protective
Protectiveness Statement: The remedy at OU1 currently protects human health and the environment
because the groundwater pump-and-treat system operated until it reached its maximum effectiveness,
and effective ICs have been implemented that prohibit potable usage of groundwater and serve to
prevent exposure to the remaining groundwater contamination at the Site. However, in order for the
remedy to be protective in the long-term, the following actions need to be taken to ensure
protectiveness:
Sample groundwater for PFAS at the Site with an approved Uniform Federal Policy-QAPP and work plan
to determine if it is present and site-related.
Pending additional data collection to evaluate possible expansion in the 1,4D plume (noted in the
monitoring recommendation below), update the ICIAP to include procedures for periodic reviews of
governmental controls to confirm compliance of nearby properties with the municipal groundwater
ordinance and to ensure there are no future exposure routes to affected areas of the unconsolidated
aquifer. Furthermore, additional deed restrictions and access agreements are required if the new
monitoring wells are added to properties lacking sufficient restrictions to ensure long-term
protectiveness.
Resolve cause of access and flooding conditions in the short-term to allow continued sampling of the
monitoring well network. Repair, modify, or replace these wells as necessary, or provide work plan to
install new wells in order to monitor and determine the groundwater COC plume's east northeastward

timeline to achieve groundwater RAOs.
Perform a climate vulnerability assessment.
Protectiveness Statement(s)
Operable Unit: OU2 Protectiveness Determination:
Protective
Protectiveness Statement: The remedy at OU2 is protective of human health and the environment
because the remedial activities completed have adequately addressed all exposure pathways that
could result in unacceptable risks to site soil and sediment. These remedial activities included operation
30
-------
of the SVE system which was successful in achieving a 97% reduction of VOCs in the subsurface soil
within the barrier wall, excavation of contaminated sediments and placement under a cap, excavation
and/or in-situ treatment of contaminated soils, and placed a soil cover over previously excavated areas
containing residual sediment concentrations to prevent direct contact.
Protectiveness Statement(s)
Operable Unit: OU3 Protectiveness Determination:
Protective
Protectiveness Statement: The remedy at OU3 is protective of human health and the environment
because the remedial activities completed have adequately addressed all exposure pathways that
could result in unacceptable risks to the areas of the Site covered by the final soil cap. These remedial
activities included fencing, deed restrictions, and completion of the final multilayer soil cap to prevent
contact with contaminated soils and sediment, including placing a soil cover over previously excavated
areas containing residual sediment concentrations.
Sitewide Protectiveness Statement
Pro tectiven ess Deter m in a tion:
Short-term Protective
Protectiveness Statement: The remedy sitewide currently protects human health and the environment
because the groundwater pump-and-treat system operated until it reached its maximum effectiveness,
and effective ICs have been implemented that prohibit potable usage of groundwater and serve to
prevent exposure to the remaining groundwater contamination at the Site. However, in order for the
remedy to be protective in the long-term, the following actions need to be taken to ensure

EPA Begins Review of
MIDCO I Superfund Site
Gary, Indiana
The U.S. Environmental Protection Agency, in consultation with the Indiana
Department of Environmental Management, is conducting a five-year review of the
MIDCO I Superfund site in Gary, Indiana. MIDCO I is located at 7400 W. 15th Ave.
The Superfund law requires regular checkups of sites that have been cleaned up -
with waste managed on-site - to make sure the cleanup continues to protect
people and the environment. This is the sixth five-year review of this site.
EPA's cleanup of contaminants from MIDCO I consisted of groundwater pumping
and treatment, air sparging (a technology which removes contaminants from
groundwater by the injection of oxygen), injection of treated groundwater into a
deep saline aquifer, soil and sediment treatment using soil vapor extraction and
solidification/stabilization, and placement of a cap over the site. The current
groundwater cleanup strategy has changed from groundwater pumping and
treatment to monitored natural attenuation.
More information is available at www.epa.gov/superfund/midco-i. The review will
be completed by September 2024.
The five-year review is an opportunity for you to tell EPA about site conditions and
any concerns you have. Contact:

X. Oil IKU REMEDIES
If there are remedies applied at the site which are not covered above, attach an inspection sheet
describing the physical nature and condition of any facility associated with the remedy. An example
would be soil vapor extraction.
XI. OVERALL OBSERVATIONS
1. Implementation of the Remedy
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 current remedy, MNA, aims to cleanup groundwater to ARARs in a reasonable timeframe. The soil and
final cap remedies along with ICs aim to contain waste left in place and ensure human health and the
environment are protected. The soil and final cap remedy are effective and protective. However, the
groundwater remedy lacks sufficient monitoring of northeastward groundwater plume movement. This
information is necessary to ensure MNA cleans up groundwater to ARARs in a reasonable timeframe.
2. 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.
Overall, the O&M procedures procedures for the remedy are being implemented effectively and the O&M
procedures, including an ICIAP and LTS plan, support long-term protectiveness of the remedy. The
remaining issue at the site is groundwater plume delineation.
3. 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 neighboring company is continuing to expand operations onto the Superfund Site and is disturbing the
remedy. Moreover, their activities are likely increasing flooding issues in the north east well field area.
4. Early Indicators of Potential Remedy Problems
Describe possible opportunities for optimization in monitoring tasks or the operation of the remedy.
The lock and key system for monitoring wells has multiple different locks and keys. This system should be
consolidated to one set of locks and keys to optimize monitoring well accessibility.
