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 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 NL Industries/Taracorp Lead Smelter Superfund Site (Site). The triggering
action for this statutory FYR was the signing of the previous FYR on April 15, 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 one sitewide operable unit (OU), which this FYR addresses. OU1 addresses soils,
groundwater, and battery case materials contamination.
The NL Industries/Taracorp Lead Smelter Superfund Site FYR was led by Aaron Green, Remedial Project
Manager (RPM), EPA. Participants included Brian Conrath and Jordan Simpkins, state agency
representatives at the Illinois Environmental Protection Agency (IEPA). Other relevant entities such as
the Potentially Responsible Party (PRPs) were notified of the initiation of the FYR. The review began on
April 12, 2023.
Site Background
The Site is the location of a former lead-acid battery breaking and secondary lead smelting facility in
Granite City, Illinois. Secondary lead smelting, metal refining, metal fabricating and associated activities
were conducted at the Site since 1903. Operations ceased at the Site in 1983. As a result of these
historical operations, metals, including lead, were released to the environment via airborne stack
emissions and fugitive dust from the 250,000-ton on-site slag pile (Taracorp Pile1), use of crushed hard
rubber battery casings as fill material throughout the community, and groundwater contamination
from the battery crusher and slag pile. The Site was added to the National Priorities List (NPL) in 1986.
See Appendix B for a Site chronology and Appendix C for figures detailing site location and soil cleanup
zones.
The projected land use for the Site includes maintenance of the landfill cap associated with the
Ta racorp Pile and the continued designated land use of the surrounding industrial, commercial, and
residential properties. The Site is divided into three areas of concern: 1) "main industrial site"
1 The Taracorp pile consists of over 250,000 tons of waste material that is primarily slag and crushed battery casings from
the former secondary lead smelter. It occupies approximately 3.5 acres and sits on a part of the main industrial area near
the corner of 1600 State Street and State Street.
1
-------
consisting of 10 properties that formerly included the lead acid battery recycling and secondary lead
smelting facility, the waste pile recycling operation, and a trucking company; 2) "remote fill areas"
which include properties in Eagle Park Acres, most of the alleys in Venice, Slough Road in Venice, and
several other locations in and around Granite City where hard rubber battery case materials containing
lead were used to fill low-lying areas; and 3) "adjacent residential areas" which are residential
properties adjacent to the main industrial site and include properties in Granite City, Venice, and
Madison, Illinois. These adjacent residential areas have been adversely impacted through airborne
deposition of lead through stack emissions and dust dispersion.

II. RESPONSE ACTION SUMMARY
Basis For Taking Action
The primary exposure pathway identified during the Remedial Investigation/Feasibility Study (RI/FS),
(O'Brien and Gere Engineers, Inc, May 1986) for the Site was direct contact and ingestion of lead-
contaminated soil and dust by small children. Lead was identified as the primary contaminant of
concern at the Site in soils. Lead, cadmium, and zinc were identified as contaminants of concern at the
Site in groundwater. There was a known blood lead problem in the communities near the Site.
Inhalation of lead-bearing dust from the onsite Taracorp pile was an additional exposure pathway of
concern, specifically for children under the age of six. The groundwater in the immediate vicinity of the
Taracorp pile is also contaminated with lead, cadmium, and zinc, but is localized and extends no more
than 200 feet from the perimeter of the Taracorp pile. The groundwater exposure pathway is not
considered to be complete because all the residents consume potable water provided by the
municipality, and the metals get buffered out within a few hundred feet of the old battery-breaking
area.
Response Actions
Initial Response
In 1993, EPA and the U.S. Army Corps of Engineers (USACE) performed a rapid response action at the
Site to remove the most highly contaminated site areas, approximately 50 locations where battery
casing fill material was located and readily accessible to children. This action involved the excavation of
soils containing hard rubber battery case chips followed by restoration with clean fill and sod. This
action was completed in 1994.
Remedy Selection Process for the Site
The remedy for the Site is contained in various decision documents including a 1990 Record of Decision
(ROD), a 1995 Decision Document (DD) reaffirming the lead clean-up standards selected in the ROD
(the record having been reopened as a component of settlement of litigation), and four Explanations of
Significant Differences (ESDs). These are discussed further below. Based on these documents, the
Remedial Action Objectives (RAOs) for the Site are a combination of achieving a 500 parts per million
(ppm) lead soil cleanup level for residential properties, and a 1,000 ppm lead soil cleanup level for
commercial/industrial properties. Groundwater cleanup levels are 15.0 micrograms per liter (ng/L) for
lead, 5.0 |Lig/L for cadmium, and 5,000 |Lig/L for zinc (See Table 1 below).

• Deed Restrictions and other institutional controls (ICs) to prevent access to the Taracorp pile;
• Deed Restrictions and other types of ICs for other properties that cannot be cleaned up to
UU/UE;
• Performance of soil lead sampling to determine which areas must be excavated and the extent
of the excavation;
• Inspection of alleys and driveways and areas containing surficial battery casing material in
Venice, Eagle Park Acres, Granite City, Madison, and any other nearby communities to
determine whether additional areas not identified in the FS must be remediated as described
below;
• Performance of blood lead sampling to provide the community with current data on potential
acute health effects associated with Site contamination;
• Installation of a minimum of one upgradient and three downgradient deep wells, monitoring of
groundwater and air, and inspection and maintenance of the cap;
• Removal and recovery of all drums on the Taracorp pile at a secondary lead smelter;
• Consolidation of waste contained in adjacent St. Louis Lead Recyclers (SLLR) piles with the
Taracorp pile and construction of a new cell with an engineered Resource Conservation and
Recovery Act (RCRA) grade liner and leachate collection system;
• Excavation and consolidation with the Taracorp pile of all unpaved portions of the adjacent
Trust 454, Rich Oil, and BV&G Transport properties having lead concentrations greater than
1000 ppm;
• Excavation and consolidation with the Taracorp pile, or off-site disposal, of all residential soils
and battery casing materials in Granite City, Madison, and Venice, Illinois, and any other nearby
communities with lead concentrations greater than 500 ppm;
• Consolidation of the soils and crushed casings and lead contaminated materials from the
adjacent waste piles into the existing Taracorp waste (slag/debris) pile if the materials do not
fail the Toxicity Characteristic Leaching Procedure (TCLP);
• Inspection of the interiors of homes on property to be excavated to identify possible additional
sources of lead exposure and recommend appropriate actions to minimize exposure, and High
Efficiency Particulate Arrestor (HEPA) vacuuming of home interiors;
• Monitoring of groundwater at the industrial facility and implementation of a contingency plan,
if needed, to remediate contaminated groundwater;
• Implementation of dust control measures during all remedial construction activities;
• Construction of a RCRA-compliant, multi-media cap over the expanded Taracorp pile and a clay
liner under all newly created portions of the expanded Taracorp pile, and construction of storm
water and erosion controls on and around the pile;
• Development of contingency plans to provide remedial action in the event that the
concentration of contaminants in groundwater or air [lead or PM10 (particulate matter greater
4
-------
than 10 microns)] exceed the Illinois Ambient Air Quality Standards, Title 35 Illinois
Administrative Code (IAC) Part 212, Subpart B and Part K, or that waste materials or soils have
become releasable to the air in the future;
• Development of Contingency Measures (CMs) to provide for sampling and removal of any soils
within the zone of contamination, defined by the soil lead sampling to be implemented above,
with lead concentrations above 500 ppm which are presently capped by asphalt or other
barriers but become exposed in the future due to land use changes or deterioration of the
existing use; and
• Monitoring of nearby communities to determine if additional areas need remediation or lead
exposures need mitigation.
Status of Implementation
Site Completion (Main Industrial Site)
The PRP Group submitted the Final Remedial Action Report (ENTACT, February 2000) detailing the
March 1999 through February 2000 on-site cleanup activities of the main industrial portion of the Site.
The cleanup consisted of excavation of soils to an established industrial cleanup performance standard
of 1,000 ppm to a maximum depth of three feet; and the consolidation of hazardous materials into the
Taracorp pile. The excavated contaminated soils from the main industrial and remote fill portions of
the Site, and the consolidated hazardous wastes (blast furnace slag, battery casings, dross, and
investigation derived wasted) were placed into a RCRA-grade waste disposal cell consisting of liner,
cap, and leachate collection system. Site restoration included the backfill of excavated areas using the
soils excavated from residential soil cleanups between 500 ppm and 1,000 ppm), topped with six
inches of stone, and construction of a permanent security fence. EPA subsequently signed the
Preliminary Close Out Report (EPA, September 2000) detailing the on-site work. The Preliminary Close
Out Report a\so includes a summary of the cleanup of adjacent residential yards and remote fill area
portions of the Site.
Residential Yards (Adjacent Residential Areas)
Approximately 1,550 residential yards were remediated during the remedial action phase of the Site
conducted from 1993 to 2000. These cleanup activities were initiated by EPA and USACE and
transitioned to the PRP Group in July 1998. Pre-excavation sampling was conducted at each residence
with two sample locations: one front yard and one back yard with samples collected at 0-3", 3-6" and
6-12" to determine excavation depth. Residential yard cleanup involved the excavation of soils where
the total lead concentration in exceeded 500 ppm. As presented EPA's 1995 ESD, excavation was to a
maximum of 12 inches as "...the sampling results show that nearly all the lead contamination over 500
ppm in the residential yards is within the first 12 inches of soil". Excavations were subsequently
backfilled with clean soils and covered with sod. At the conclusion of the residential yard cleanup
activities in 2000, there were 84 property owners who denied access for soil sampling and/or
remediation.
In 2006, the PRP Group agreed to work with EPA to reattempt access to these previously 84 denied
access properties in lieu of implementing ICs on these properties. Three properties were found to be
5
-------
industrial/commercial properties and not subject to the residential assessment and required to
cleanup to industrial criteria. The PRP Group was successful in obtaining access to sample 66 of the
initial 84 denied access properties, of which 28 properties were found to be below the 500-ppm
residential cleanup standard while 38 properties required yard remediation due to exceedances of the
lead standard. The Remedial Action Report (EWI, July 2017) details the work conducted between 2006
through 2017 to assess these original 84 denied access residential properties.
There are 15 remaining residential properties in which the owners cannot be located, are
unresponsive, or continue to deny access. These 15 denied-access properties are routinely inspected
via roadside assessments to determine if there are any observed disturbance of soils. EPA, I EPA, and
the PRP Group have been working to place notice of potential environmental conditions on these
property deeds.
In January 2024, EPA announced updates to guidance for lead in residential soil at Superfund sites,
Updated Residential Soil Lead Guidance for CERCLA Sites and RCRA Corrective Action Facilities (EPA,
January 2024). EPA lowered recommended screening levels and strengthened guidance for
investigating and cleaning up lead-contaminated soil in residential areas where children live and play.
This new guidance will require a re-evaluation of the past residential cleanup efforts to determine if
selection of a new soil cleanup level for lead is necessary to ensure the remedy remains protective.
Remote Fill Sites
The remote fill cleanup activities were initiated by EPA and USACE in 1993 and transitioned to the PRP
Group in July 1998. The remote fill cleanup activities were completed by 2000. Approximately 105
properties and 58 unpaved alleys were identified as remote fill sites where battery case chips were
historically used as fill material in low lying areas. These remote fill sites included properties and alleys
in the Eagle Park Acres, Venice, Madison, and Granite City residential neighborhoods. Remote fill areas
also include most of the alleys in Venice; Slough Road in Venice; one alley in Glen Carbon, Illinois; and
several other locations in and around the general area of Granite City.
Of these remote fill sites, 17 properties and 15 alleys were sampled and were determined to not
require remediation as the total lead concentration was below the selected 500 ppm residential lead
soil cleanup level. Eighty-eight residential properties required cleanup which involved the excavation of
soils where the total lead concentrations in soil exceeded 500 ppm with a maximum excavation depth
of 3 feet. Restoration included bringing areas back to grade with clean soils and covering with sod.
The 43 alleys were addressed through a combination of excavation and/or encapsulation with a
minimum of two inches of asphalt pavement. Initially the remote fill contaminated alleys were subject
to the same cleanup method as the residential properties (i.e., excavation of soils where the total lead
concentrations in soil exceeded 500 ppm to a maximum excavation depth of 12 inches and returning
area to grade and paved). The DD/ESD dated September 29,1995 (EPA, September 1995), however,
details that the most highly contaminated of the remote fill alleys have been remediated through
excavation and that the remaining alleys that do not greatly exceed the 500 ppm lead cleanup level will
be paved with no excavation as the pavement provides a barrier from potential exposure. The remote
fill site cleanup activities are detailed in the Final Report for Remediation of Locations in Granite City,
6
-------
Madison, and Venice, Illinois Associated with NL Industries/Taracorp Superfund Site (OHM, February
1999) and the Final Remedial Action Report, Residential and Remote Fill Areas, Granite City, Illinois
(ENTACT, July 2002).
EPA, I EPA, and the PRP Group are working with the City of Venice to adopt an ordinance to protect the
integrity of the alley pavement barriers. Once an ordinance is established, it will be presented to
Madison and Granite City for their consideration for adoption of similar ordinances.
Since the completion of the remote fill site cleanup activities, five vacant properties have been
identified as requiring additional assessment as battery case chips are observed sparsely distributed on
the ground surface. Four of these properties were previously cleaned up by EPA and USACE in the mid-
1990s and had contaminated soils excavated. However, the historic field documentation is either
missing or lacks the necessary detail to explain the observed battery case chips. A sparse distribution of
battery case chip was observed at the fifth vacant lot after heavy vegetation was cleared leaving bare
soils. These five vacant remote fill sites will require further assessment to determine whether soil lead
concentrations exceed cleanup criteria.
Contingency Measures (CMs)
The ROD required the development of CMs to provide for sampling and removal of any soils within the
zone of contamination with lead concentrations above 500 ppm which are presently capped by asphalt
or other barriers but could become exposed in the future due to land use changes or deterioration of
the existing barrier. Based on recommendations from EPA and information gained during the semi-
annual site inspections, the PRP Group has completed multiple CMs. For example, the PRP Group
remediated at least five properties originally identified as being limited to commercial use (such as
through examining zoning maps) but in fact had some type of residential use. Also, the PRP Group has
expanded the semi-annual O&M inspections to include some areas where residual contamination
might impact properties with residential uses, such as locations on Sand Road and Schaeffer Road.
In 2016, the PRP Group agreed to canvass or look for properties in the Site area that the CM's provision
could cover and submit a visual canvassing report to EPA and IEPA. The PRP Group prepared the
Contingency Measure Workplan (NL Industries/Taracorp Superfund Site Group, January 2017) which
identified four properties to be sampled for lead contamination in soil. These properties were
identified due to the deterioration of a previous existing barrier such as sidewalk or driveway. EPA and
IEPA implemented the Workplan, using special account funds at the outset. Sampling results indicate
that the lead concentrations from these four properties were below the Site cleanup level of 500 ppm
for soil, and therefore, no additional measures were taken at those locations. Given EPA's updates to
the residential lead screening levels in January 2024, the data collected at these residential properties
and others previously assessed and/or cleaned up will be re-evaluated to determine if a new cleanup
level for lead is appropriate to protect human health and the environment.
Supplemental Environmental Project (SEP)
Although not required in the ROD nor required to be evaluated as part of this FYR, certain activities
comprising a SEP were negotiated as part of the Consent Decree (CD) with the PRP Group. The SEP
7
-------
became a component of the United States' settlement of CERCLA claims against the PRP Group,
reflected in a civil CD. These activities are consistent with EPA's Superfund Residential Lead Sites
Handbook, OSWER 9285.7-50, August 2003, which recommends multi-media cleanups of lead when
possible. The SEP's general goals were to assess and address hazards from lead-based paint within the
Site boundaries by paint abatement and HEPA vacuuming. The SEP was developed to fund a program
with Madison County Community Development Agency (MCCDA) that addressed concerns with the
potential for deteriorating exterior lead-based paint to contaminate and re-contaminate residential
yard soil. Additionally, the SEP was developed to address potential lead in indoor dust from
deteriorating indoor lead paint.
The PRP Group completed the SEP which consisted of residential lead paint assessment and abatement
measures in March 2017 and provided the SEP Completion Report (NL Industries/Taracorp Superfund
Site Group, May 2017). This report was prepared in consultation with the MCCDA and contains
documentation from the 130 risk assessment reports and 127 clearance reports from MCCDA's
consultants. More information can be found in Appendix D.
Institutional Controls
ICs are non-engineered instruments, such as administrative and/or legal controls, that help minimize
the potential for exposure to contamination and protect the integrity of the remedy. Compliance with
the ICs is required to assure long-term protectiveness for any areas that do not allow for UU/UE.
The ROD and other decision documents for the Site state that ICs are required for the main industrial
portion of the Site, which includes the capped Taracorp pile, other parcels on the main industrial area,
and Site-impacted groundwater, although the specific types of ICs were not designated therein.
Additional areas where ICs are needed are as follow: the 15 adjacent residential areas whose owners
refused access, could not be found, or were unresponsive, and the remote fill areas where paved
barriers cover battery case fill. A summary of the planned ICs for the Site is discussed below and
summarized in Table 2.

A series of maps showing the areas where the ICs are needed are included in Appendix C (Figures 4a
through h).
Status of Access Restrictions and ICs:
Access restrictions consisting of fencing and signage are in place around the Taracorp pile. These
controls, along with the continued presence and security at Metalico (current owner of the former
smelter property) deter trespassers and appear to be effective measures to limit access to the
Taracorp pile. However, none of the required ICs are in place and are still in the process of being
implemented for the Site.
EPA is working with the IEPA and the PRP Group to finalize the Institutional Control Work Plan (ICWP),
most recently updated July 2013 (NL Industries/Taracorp Superfund Site Group, July 2013). Remaining
work includes finalizing the ECs and notice of environmental conditions language, and working with the
cities of Venice, Madison, and Granite City on the adoption of an ordinance and a communication plan
for road and alleyways. EPA expects to approve the final comprehensive ICWP by September 30, 2025.
The updated and finalized ICWP will address:
• ECs compliant with the Illinois UECA (These ICs are often also known as deed restrictions.);
• A one-call notification program, including an excavation advisory, to be implemented through
JULIE, the Illinois one-call notification system (see right below for further details);
• Review of title work and planning for any additional ICs that may be needed;
• An ordinance for the Venice, Madison, Granite City road and alleyways;
• A Communication Plan for the Venice, Madison, Granite City road and alleyways;
• Biennial notification letters to certain property owners;
• Revision of the ICWP; and
• A Long-Term Stewardship (LTS) Plan
10
-------
The PRP Group has investigated the use of the Illinois one-call system, "JULIE", as an informational IC.
To that end, the PRP Group has had discussions with representatives of Consolidated Utilities Services,
Inc. and e-Locate Services, LLC related to the possibility of including some of the properties associated
with the Site in the Illinois' one-call program. An excavation advisory has been prepared and is included
in Appendix E. The PRP Group prepared an excavation advisory, under EPA and lEPA's direction, for
some of the areas that are likely to have battery chips or residual soil contamination, and which will be
used in conjunction with the one-call notification program. The PRP Group also provided maps to EPA
within the ICWP that will be used with the one-call system to show the properties that will be part of
the one-call notification program for the Site.
Current Compliance with Intended Use Restrictions:
Taracorp Pile Cap Integrity and Land Use Restriction: Based on the June 29, 2023 site inspection and
the October 5, 2023 FYR site inspection of the industrial portion of the Site, there is no current use of
the waste pile/landfill, and industrial uses on adjacent parcels are not anticipated to impact it. The
hazardous waste cap must remain in place indefinitely to prevent exposure to underlying waste.
Groundwater Use Restriction: The main industrial area is currently zoned for industrial use, is being
used for commercial/industrial purposes, and is serviced by municipal water. Based on the June 29,
2023 and October 5, 2023 inspections and groundwater sampling activity (see Data Review Section
below), the groundwater contamination remains within the industrial area, and access to that area is
limited by perimeter fences.
Denied Access Residential Yards: Fifteen residences remain unsampled and/or unremediated and
without use restrictions. The PRP Group periodically performs a street view assessment of these
denied access properties to identify activities that could potentially result in contaminated soil
exposure. During the PRP Groups' Second 2023 Semi-Annual Operation and Maintenance Inspection
on October 4, 2023 and the October 5, 2023 FYR inspection there were no observed issues such as
removal of vegetative covering or soil disturbance which could potentially cause an exposure to
underlaying lead contaminated soils.
Remote Fill Alleys: Based on the June 29, 2023 and October 5, 2023 inspections, the paved coverings
are intact for the 43 remote fill alleys which were paved to eliminant exposure to the underlying lead
contaminated soils.
Long Term Stewardship:
LTS involves assuring effective procedures are in place to ensure that the Site remedy's components,
including effective ICs, are maintained and monitored so that the remedy continues to function as
intended. The LTS plan to be implemented will be part of the O&M plan and will function in
coordination with the ICWP and include: (1) provision for an annual certification to EPA and IEPA that
ICs are in place and effective; (2) a communications plan; and possibly (3) the use of the Illinois' one-
call system for certain areas.
11
-------
IC Follow-up Actions Needed
Although preliminary comments have been submitted to the PRP Group, EPA must approve the
updated ICWP, and both the PRP Group and EPA must conduct IC activities to ensure effective ICs are
implemented. If an IC that is not contemplated in the ROD is proposed in the ICWP, and deemed
necessary for purposes of protectiveness, EPA will prepare an ESD to specify and incorporate the
additional ICs needed as part of the Site remedy. In addition, as discussed above, a LTS plan will be
developed as part of the O&M plan.
Systems Operations/Operation & Maintenance
During the period of this FYR, the PRP Group continued to perform operation and maintenance (O&M)
activities according to the Site's O&M Plan, Operation and Maintenance Plan (NL Industries/Taracorp
Superfund Site Group, June 2002). O&M inspections were performed on a semi-annual basis at the
Site. Based upon those inspections and other observations, the PRP Group and its contractor, Munie
Greencare Professionals, performed the following maintenance activities on an as-needed basis:
• Vegetation was mowed on the Taracorp pile and surrounding areas at the main industrial area;
• Herbicide was applied to control the growth of vegetation on and near the perimeter security
fence, and along the sidewalk on 1555 State Street. Herbicide was also applied to control
emergent woody vegetation;
• Animal (i.e. - groundhog) burrows were filled to maintain integrity of the Taracorp pile cap;
• Repairs to the perimeter security fence were conducted;
• Surface water drainage swale was inspected, and vegetative debris was removed around the
Taracorp pile; and
• Leachate was removed from the leachate sump and properly disposed.
In addition to the OLJ1 inspection and maintenance activities, the PRP Group inspected remote fill
areas, numerous paved alleys that cap contaminated soils in Eagle Park Acres and Venice, as well as
monitoring conditions and activities at several denied access properties. No issues were observed
during these expanded sitewide inspections.
The CD requires the PRP Group to undertake periodic progress reporting to EPA. The PRP Group has
continued to submit progress reports to EPA on a quarterly and semi-annual basis since the last FYR.
Copies of the recent quarterly progress report Consent Decree - Quarterly Monitoring Report 71
(Montrose Environmental, October 2023) can be found in Appendix F. The Second 2023 Semi-Annual
Operation and Maintenance Inspection (Montrose Environmental, October 2023) can be found in
Appendix G.
Groundwater and leachate are sampled every five years according to the approved Scope of Work
Groundwater Monitoring for Five-Year Review {NL Industries/Taracorp Superfund Site Group,
December 2008). During the week of September 11 to 15, 2023, the Group's contractor, EWI, assessed
and redeveloped groundwater monitoring wells at the Site, collected groundwater samples, and
pumped leachate from the landfill leachate collection sump. Leachate and groundwater samples were
12
-------
submitted for laboratory analysis of both total (unfiltered) and dissolved (filtered) lead, cadmium, and
zinc using USEPA Method SW-6010D. EWI received approval from the Granite City Wastewater
Treatment Plant to pump monitor well development/purge water (i.e., investigation derived waste)
and collected leachate from a storage tank into a sanitary sewer manhole at 16th Street and Edison
Street in Granite City for subsequent treatment at the Granite City Wastewater Treatment Facility. The
results of this sampling event were submitted to EPA in Five-Year Review 2023 Groundwater
Monitoring Report (EWI, November 2023) and can be found in Appendix H (See Data Review Section
for further information on the results of this sampling event).
The Site's O&M Plan will require updates following the finalization of the ICWP. The updated O&M
Plan will incorporate IC and LTS obligations.
III. PROGRESS SINCE THE LAST REVIEW

Protectiveness
Determination
Protectiveness Statement
1 and Sitewide
Short-term Protective
The remedy at the NL Industries/Taracorp Lead Smelter Site
currently protects human health and the environment because: the
final remedy has been fully implemented (except at the residences
that have refused access); the sampling data indicate that the
remedy continues to be effective in addressing the exposure
pathways that were identified at the Site; there is no evidence of
current unacceptable exposures; and the groundwater
contamination is confined to the former lead smelter property. An
additional measure of protection was realized at the Site through
the implementation of a SEP to address lead-based paint issues in
the Site area. This SEP helped to provide a multi-media lead cleanup
which is recommended by EPA guidance that goes beyond the
requirements in the ROD for the Site. In order for the remedy to be
protective in the long term, the following actions need to be taken
to ensure protectiveness: effective ICs need to be implemented;
compliance with ICs needs to be ensured by adopting LTS
procedures that maintain, monitor, and enforce effective ICs as well
as maintaining the site remedy components; and the Remedy
Decision Documents need to be reviewed to determine if
clarification is required regarding additional ICs. If so, appropriate
documentation such as an ESD should be completed. Last, EPA will
continue to require O&M inspections and groundwater monitoring,
the PRP Group will update the O&M Plan, and EPA will continue
implementing contingency measures.

next FYR cycle.
IV. FIVE-YEAR REVIEW PROCESS
Community Notification. Involvement & Site Interviews
Public notice was made available on EPA Region 5 Events - Five Year Review Public Notices and NJL
Industries/Taracorp websites on December 14, 2023, stating that there was a FYR and inviting the
public to submit any comments to EPA. No comments were received. The results of the review and the
report will be made available at the Site information repository located at the Granite City Hall Clerk's
office at 2000 Edison Ave, Granite City, IL and on EPA's website located at: NL Industries/Taracorp
(https://cumulis.epa.gov/supercpad/cursites/csitinfo.cfm?id=0500507).
Interviews
The EPA RPM maintains regular communication with PRP Group's Site Project Manager, Mr. Jeff Leed
of Leed Environmental, and IEPA Project Managers, Jordan Simpkins and Brian Conrath regarding the
Site O&M, monitoring, and IC implementation. Periodic meetings have been held between
representatives of the PRP Group, EPA and IEPA. These discussions and the FYR interview identified
continued success in the maintenance of the Taracorp pile cap and access restrictions, and that the
asphalt paving on the remote fill alleys is being maintained. Areas identified as needing work or
15
-------
progress include the lack of a finalized ICWP and approved IC language for industrial portions of the
Site.
No specific community interviews were conducted during the FYR process. During the FYR process, EPA
and IEPA have had several communications with a developer group of low-income housing
developments who is exploring options in the City of Venice. In these discussions, EPA and IEPA have
explained past cleanup work and the preservation of the asphalt paving on the remote fill alleys. EPA
and the PRP Group have also had communications with the Venice city attorney and Mayor to explore
the possibility of implementing a City ordinance that would help ensure the asphalt paving on the
remote fill alleys remain intact.
Data Review
Groundwater and Leachate Sampling
Groundwater flows in a generally south-southwesterly direction within the uppermost aquifer beneath
the Main Industrial Site. The groundwater analytical results were compared to the groundwater
cleanup standards for the Site, which are the Maximum Contaminant Levels (MCLs) of 5 |Lig/L for
cadmium, and the Secondary Maximum Contaminant Levels (SMCLs) of 5,000 for zinc, and the EPA
action level of 15 |Lig/L for lead. The results are discussed below.
The monitoring well network consisting of fifteen wells were sampled with cleanup standard
exceedances observed in two nested monitoring well locations GMMW-107 and GMMW-108, which
are located directly downgradient from the former battery breaker. The results are summarized in the
table below; exceedances of the performance standards are highlighted in orange.

The metals detected above the associated performance standards during the September 2023
sampling event are consistent with historical analytical results. Total lead has been detected at
concentrations above the groundwater performance standard in monitoring wells GMMW-107S,
GMMW-107D, and GMMW-108D. In 2009, it was concluded that the total lead results were due to
suspended sediment in samples and not attributable to the former source area. Starting in 2014, both
total (unfiltered) and dissolved (filtered) metals samples were taken at each location. None of the
samples have had detections of dissolved lead above the groundwater performance standard.
GMMW-108S and GMMW-108D, located directly downgradient from the source area, have
consistently had detections for total and dissolved cadmium and zinc, although the contaminant
16
-------
concentrations have had overall decreasing trends since the initiation of groundwater sampling
activities in 2000. Cadmium and zinc concentrations in the monitoring wells further downgradient from
the source area were non-detect supporting that groundwater contamination is confined to the former
smelter property and that no one is being exposed to contaminated groundwater because the area is
serviced by municipal water. Based upon the groundwater monitoring, it has been determined that
groundwater contamination continues to be confined to the former smelter property. EPA
recommends that the PRP Group continue to monitor groundwater and provide the results pursuant to
the EPA approved Scope of Work Groundwater Monitoring for Five-Year Review (NL
Industries/Taracorp Superfund Site Group, December 2008).
Background Lead Soil Concentrations
In determining the existing residential lead cleanup level of 500 ppm (ROD, 1990 and BSD 1995), a
background assessment was not conducted as it was concluded that the lead soil background for the
St. Louis metropolitan area does not approach the residential cleanup criteria of SOOppm. Pursuant to
the 1995 BSD (EPA, September 1995), "...[soil] background for the area appears to be between 100-200
ppm lead..."; however, a formal background soil lead assessment was not performed and therefore
background lead levels at the Site remain unknown. In response to the Updated Residential Soil Lead
Guidance for CERCLA Sites and RCRA Corrective Action Facilities (EPA, January 2024) which lowered
recommended screening levels, it will be necessary to evaluate naturally occurring lead and regional
(non-site specific) anthropogenic lead levels at the Site to determine if a new residential soil cleanup
level for lead is necessary.
Site Inspection
The FYR inspection of the Site was conducted on October 5, 2023. In attendance were Aaron Green,
RPM, representative of EPA; Brian Conrath of I EPA, representative of the supporting state agency; and
Jeff Leed, Leed Environmental, Project Coordinator from the PRP Group. The purpose of the inspection
was to assess the protectiveness of the remedy. The inspection findings confirmed that the remedy at
the Site is following the requirements of the ROD and ESDs.
The integrity of the covering/caps for the alleyways remains in good condition and there is no evidence
of exposure from the battery chips from the alleys. A sparse distribution of battery chips was observed
at Sand Road and Schaeffer Road properties. These are both vacant lands and consist of two of the five
properties previously identified as having dispersion battery case chips on the surface of the soil. The
fence surrounding the Taracorp pile, and the cap and vegetative covering are in good condition and
being well maintained. Warning signs were evident on the fence. The FYR checklist is attached as
Appendix I along with the Site photographs from the inspection.
V. TECHNICAL ASSESSMENT
QUESTION A: Is the remedy functioning as intended by the decision documents?
Yes, the remedy is functioning as intended with the exception of ICs because they are not yet in place.
17
-------
Question A Summary:
Remedial Action Performance
The remedial actions described in the decision documents have been implemented and the cleanup
objectives have been met with exception of groundwater in a localized portion of Site near the former
battery crusher. During the remedy selection process, the primary exposure pathways identified at the
Site were direct contact and ingestion of lead-contaminated soil and dust, and the secondary pathway
was inhalation of fugitive dust from the Taracorp pile. Based on the visual observations during
inspections and the site monitoring, the remedy has been effective in addressing the primary and
secondary exposure pathways.
The October 2023 FYR Site inspection of the cap on the Taracorp pile by EPA indicates that the cap is in
good condition, thus preventing the generation of fugitive lead dust which could be generated by
blowing off an uncovered waste pile. Warning signs are installed on the perimeter fencing which is
located around the pile. The fencing is in good condition with no evidence of unauthorized entry into
the site. Inspections are conducted at least twice per year. These inspections also indicate that the
remedy has been effective in addressing the secondary exposure pathway.
Last, groundwater must continue to be monitored by the PRP Group during each FYR period to verify
that the lead, cadmium, and zinc in the groundwater in the vicinity of the Taracorp pile has not
migrated. Groundwater monitoring is not needed more frequently because the metals of concern in
the groundwater tend to be quite stable and not mobile. In the past, the levels of these constituents
generally decreased in the wells adjacent to the Taracorp pile, which is expected since the cap diverts
most of the runoff away from the pile. EPA approved the FYR groundwater monitoring event which
was conducted during the week of September 11-15, 2023, and which demonstrated that groundwater
contamination has not migrated off the main industrial area at the Site. Also, no one is using the
groundwater in the main industrial area of the Site and the area is serviced by municipal water.
In summary, the data gathered during this sixth FYR indicates that the remedy continues to function as
designed, is performing as expected, and that the containment of remaining contaminants is effective.
System Operations and Maintenance/O&M
The remedy for the Site includes capped areas but does not include any operating systems. The Site is
inspected at least twice per year. Maintenance and repairs to the cap are completed as needed and
according to the approved O&M Plan. These inspections have been and will continue to be an effective
means to ensure cap integrity.
The O&M Plan will be updated to include LTS procedures for ICs once all components of the ICWP are
finalized, and ICs are in place.
18
-------
Implementation of Institutional Controls and Other Measures
Access controls in the form of fencing are in place at the Taracorp pile. These controls, along with the
continued presence of Metalico Granite-City, Inc. (current owner of the former smelter property)
employees at the Site, are effective measures to limit access to the Taracorp pile. Also, since the last
FYR, warning signs have been established on the fencing surrounding the Taracorp pile. However, none
of the required ICs are in place yet. EPA will continue to work with the PRP Group to ensure that ICs are
put into place. EPA will consider the use of informational ICs (e.g., deed notices of environmental
conditions) at the 15 residences that have denied access or been unresponsive to requests for access.
Finalization of the ICWP is pending. This ICWP will include continued work on the environmental
covenant and notice of environmental conditions language, work with the cities of Venice, Madison,
and Granite City on the adoption of ordinance and a communication plan for road and alleyways. EPA
will prepare an ESD to specify and incorporate the additional ICs needed as part of the Site remedy. In
addition, a LTS plan will be developed to be included as part of the O&M plan update.
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?
No
Question B Summary:
Changes in Standards and To Be Considered Criteria (TBCs)
There are changes to standards orTo Be Considered criteria which will warrant further evaluation. The
1990 ROD (EPA, March 1990) details the selection of the lead cleanup levels of 500 ppm for residential
soil and 1,000 ppm for industrial soil. The selection of the residential soil cleanup level was developed
using the Integrated Exposure Update Model (IEUBK model) to evaluate risk using exposure
assumptions including soil lead and dust lead exposure in combination to other daily lead exposure
risks (i.e., food lead levels, lead in plumbing, lead-based paint, etc.) to predict blood lead levels in the
most vulnerable population, children. As presented in the 1990 ROD, "...EPA Region Vhas set a 500
ppm lead soil clean-up level at the NL/Taracorp Superfund site. It is the best professional judgement of
the staff that this level represents the minimum soil clean-up level which can be expected to protect the
most sensitive Granite City residents, children under the age of six years."
In January 2024, EPA announced updates to guidance for lead in residential soil at Superfund sites,
Updated Residential Soil Lead Guidance for CERCLA Sites and RCRA Corrective Action Facilities (EPA,
January 2024). EPA lowered recommended screening levels and strengthened guidance for
investigating and cleaning up lead-contaminated soil in residential areas where children live and play.
Evolving science regarding lead exposure to children resulted in the EPA Office of Land and Emergency
Management (OLEM) lowering the target blood levels from that used in the 1990's. While not de facto
cleanup standards and referenced for comparison purposes only, the CERCLA Regional Screening Level
(RSL) has been revised under this new lead guidance from 400 ppm to 200 ppm for residential soil lead
and to 100 ppm if an additional source of lead is identified (e.g., lead water service lines, lead-based
19
-------
paint, non-attainment areas where the air lead concentrations exceed National Ambient Air Quality
Standards [NAAQS]).
A preliminary review of the data has identified residences sampled that previously required no cleanup
due to soil concentrations being below the 500 ppm residential lead cleanup level, but which now
exceed the new residential soil RSL of 200 ppm. In response to the updated residential soils lead
guidance, the residential lead soil cleanup level will be re-evaluated and will include a background
assessment to determine the extent of naturally occurring lead and regional (non-site specific)
anthropogenic lead levels that may be contributing to lead soil levels at the Site. Such an assessment of
background lead levels will be needed prior to determining if and what new residential soil cleanup
level for lead may be needed and whether additional remedial action is needed in the residential areas.
EPA will utilize the updated lead guidance to evaluate the protectiveness of the remedy for both
remediated and un-remediated residential areas of the Site, and new lead cleanup levels will be
developed as appropriate. As a result of this evaluation, it will be determined if and what additional
response actions are needed at the Site for ensuring protectiveness.
Changes in Toxicity and Other Contaminant Characteristics
The primary contaminant of concern for the Site, lead, is generally inert, so there has been no change
in contaminant characteristics or understanding of fate and transport. However, as outlined in EPA's
updated lead guidance, the science regarding lead exposure risk to children has evolved, effectively
lowering the target blood levels from that used in the 1990 IEUBK model.
Changes in Risk Assessment Methods
Evolving science regarding lead exposure to children resulted in the OLEM lowering the target blood
levels from that used in the 1990s. This change in target blood levels is anticipated to change the IEUBK
model used to derive the residential lead cleanup standard in the Site's ROD (EPA, March 1990). As
indicated above, there is a need to re-assess Site data and cleanup conducted to date using the new
residential lead guidance and to re-evaluate the current selected residential soil lead cleanup level and
develop a new residential cleanup level, as appropriate. Also, it will be determined if additional
response actions are needed at the Site for ensuring protectiveness.
Changes in Exposure Pathways
Evidence of dispersed battery chips have been found at five vacant properties including Sand Road and
Schaeffer Road. Four of these properties were previously cleaned up by EPA and USACE in the mid-
1990s with the excavation of contaminated soils. However, the historic field documentation is either
missing or lack the necessary detail to explain the observed battery case chips. A sparse distribution of
battery case chip has been identified at the fifth vacant lot after heavy vegetation was cleared leaving
bare soils.
Under the new lead guidance, the protectiveness of the remedy with respect to the battery chips at
these and other locations that have been cleaned up will be re-assessed. As necessary and appropriate,
20
-------
new cleanup levels will be developed, and it will be determined if additional response actions are
needed at the Site for ensuring protectiveness.
Expected Progress Towards Meeting Remedial Action Objectives
The remedy for the Site has progressed as expected. RAOs have been met at the Site, and the
monitoring program will continue to ensure that any changes in contaminant levels will be detected
and addressed, if necessary. Approximately 1,550 properties have been remediated. As previously
mentioned, 15 property owners have not yet agreed to allow access for sampling or remediation.
These properties will be addressed by the implementation of ICs (i.e. Notice of Environmental
Conditions via Deed Notices).
The new lead guidance will require re-evaluation of the RAOs for both remediated and un-remediated
residential areas of the Site.
QUESTION C: Has any other information come to light that could call into question the
protectiveness of the remedy?
No
There are no newly identified risks not already covered in Questions A or B above, or any newly
identified adverse effects from climate changes or from natural disasters.

OTHER FINDINGS
In addition, the following are recommendations that were identified during the FYR and will help
ensure that the remedy remains effective but do not affect current nor future protectiveness:
• The O&M plan will be updated to include IC and LTS obligations once the ICWP is finalized.
• EPA will evaluate the Contingency Measures which is stated in previous FYR to expired March
2023 and determine if extension is warranted. This includes evaluation of the five vacant
properties identified as requiring additional assessment as battery case chips are observed
sparsely distributed on the ground surface.
• The PRP Group will continue to monitor groundwater and provide the results to EPA for each
FYR.
VII. PROTECTIVENESS STATEMENT
OU1 and Sitewide Protectiveness Statement
Protectiveness Determination: Planned Addendum
Protectiveness Deferred Completion Date:
April 15, 2026
Protectiveness Statement:
A protectiveness determination of the remedy at the NL Industries/Taracorp Lead Smelter Site cannot
be made at this time until further information is obtained. Further information will be obtained by
taking the following actions: re-assess Site data and cleanup conducted to date using the new
residential lead guidance to evaluate the protectiveness of the current selected residential soil lead
cleanup level and determine a new residential cleanup level, as appropriate. Also, it will be
determined if additional response actions are needed at the Site for ensuring protectiveness.
It is expected that these actions will take approximately two years to complete at which time a
protectiveness determination will be made.

Supplemental Environmental Project Details
Although not part of the ROD, the SEP was negotiated as part of the CD with the PRP
Group. The general goals of the SEP were to assess and abate hazards from lead-based paint
within the Site boundaries. The SEP was consistent with EPA's SuperfundResidential Lead
Sites Handbook, OSWER 9285.7-50, August 2003, recommending multi-media cleanups of
lead, when possible. The SEP was developed to fund a program with MCCDA to address
concerns identified with potential contamination and recontamination of lead in soil of
residential yards due to deteriorating exterior lead-based paint. Additionally the SEP was
developed to address potential lead in indoor dust due to deteriorating indoor lead paint.
The general goals of the SEP were to assess and abate hazards from lead-based paint within
the Site boundaries by paint abatement along with HEPA vacumming of the home. The SEP
was closed in March 2017. The final report was provided to EPA on May 12, 2017.
The Group's project coordinator sent the SEP Completion Report, which the Group prepared in
consultation with MCCDA, to EPA on May 12, 2017. That report contained documentation from
the 130 risk assessment reports and 127 clearance reports that were prepared by the MCCDA's
consultants.
The paint SEP was funded with $2,000,000 for paint chip assessment and abatement at
residences within the Site area. The PRP Group entered into an arrangement with the
MCCDA to conduct a lead-based paint abatement program in Madison County. Under that
provision, the PRP Group would conduct a SEP to address lead-based paint for those homes
within the Site area which were at risk. EPA provided oversight of the paint SEP and has
approved the SEP Work Plan. The SEP work concluded in 2017 as is discussed further
below.
A SEP Work Plan wa£ issued to EPA in 2004 by the MCCDA and it was approved with
modifications in 2004. As part of the SEP work, the PRP Group prepared a master list of
properties. A public kick-off meeting was held in Granite City in 2005 to announce the SEP.
The MCCDA actively sought participants for the lead-abatement program. For example, on
February 1, 2006, an article was placed in the Granite City Press Record explaining the
program and requesting applicants. Also, one of the MCCDA lead program staff members
helped at a school registration in the Madison School District and handed out promotional
items, and the MCCDA developed door hangers to place on the doors of the homes in
Granite City, Madison and Venice. The MCCDA continued to seek additional applicants for
participation in the SEP and continued to perform the SEP for applicants who had been
accepted into the program. EPA continued to monitor the SEP under the terms of the CD to
attain a multi-media cleanup at the Site. Several extensions of time were agreed to by EPA
to complete the SEP under the March 20, 2003 CD. In March 2014, EPA extended the date
by three years for completion of the SEP until March 8, 2017. That work has now
concluded.
The PRP Group issued periodic progress reports to EPA documenting SEP efforts and
expenditures. On the PRP Group's behalf, the MCCDA continued to implement the SEP
-------
during the period from March 2009 through March 2017, and MCCDA completed lead paint
assessments at 40 residential properties and performed lead paint mitigation and clearance
activities at 41 residential properties within the boundaries of the Site. For the SEP,
MCCDA has completed lead paint assessments at 118 residential properties and lead paint
mitigation activities and clearance activities at 115 residential properties. MCCDA
representatives met with the Mayor of Granite City, attended health fairs, and.performed
other public outreach activities to encourage additional property owners to participate in the
SEP. The PRP Group submitted MCCDA's SEP reports to EPA on a periodic basis to
document the work performed by MCCDA.
The Group's project coordinator sent the SEP Completion Report, which the Group prepared in
consultation with MCCDA, to EPA on May 12, 2017. That report contained documentation from
the 130 risk assessment reports and 127 clearance reports that were prepared by the MCCDA's
consultants. The PRPs documented that they had spent approximately $1,100,000 on the SEP.
EPA sent a demand letter for the remaining funds which were due and the Group made that
payment.

-------
J.U.L.I.E. Ticket No.
Name:
Address:
EXCAVATION ADVISORY:
FOR NL INDUSTRIES/TAR AC ORP SUPERFUND SITE
IN GRANITE CITY, MADISON, AND VENICE ILLINOIS
PLEASE REVIEW THIS IMPORTANT HEALTH AND SAFETY INFORMATION BEFORE YOU DIG
AT THIS ADDRESS AND PROVIDE THIS INFORMATION TO EVERYONE WHO WILL PERFORM
WORK AT THIS ADDRESS,
J.U.L.I.E., the Illinois One-Call System, has notified the NL Industries/Taracorp Superfund Site Group and its
contractor, e-Locate Services LLC (ELS), that you called J.U.L.I.E. because you plan to dig into or excavate soil that is,
or may be, contaminated with lead from a closed lead smelter in Granite City, Illinois. Please read this information
regarding potential health hazards and other important information.
LEAD-CONTAINING SOIL AND
BATTERY CASE CHIPS
When you dig or excavate at the address indicated above, you
may find lead-containing soil or battery case chips. Battery case
chips are small (normally 1/2-inch to 2-inch diameter, but can be
smaller or larger) pieces of black hard rubber (newer chips may
also be other colors or white pieces of plastic) that came from
crushing or shredding lead-acid car or truck batteries during
recycling. Battery case chips are usually flat but may have a
triangular shape if they came from the corner of the battery case.
PROTECTIVE MEASURES
When you dig or excavate at the address indicated above, the
best way to protect yourself from potential lead exposure is to
avoid contact with lead-containing soil and battery case chips. If you cannot avoid handling lead-containing soil
and battery case chips, you should use the following good work practices and protective measures:
• Keep people away from the work area, especially children. Also, keep pets away from work area.
• Keep the soil moist to control dust.
• In dusty areas, wear a dust mask or respirator to minimize inhaling or swallowing airborne dust or soil
particles.
• Wear protective clothing (boots, shirts, pants, and gloves) and launderthe protective clothing separately
from other clothes after completing each day's work.
• Do not drink, eat, or smoke, or do anything that may put soil or dust into your mouth.
• Wash all exposed body surfaces and your hair, preferably by showering, after completing each day's work.
• Avoid tracking soil into your home. If this occurs, clean it up immediately.
DISPOSAL AND PROPERTY RESTORATION
If you are digging or excavating at the property and find battery case chips and soil that may possibly contain high
levels of lead, you should:
¦ Protect yourself from potential lead exposure by following the protective measures listed above, and
¦ Dispose of the battery case chips and soil in one of the following ways:
• If you are a residential property owner and find a small amount of battery case chips, remove the
battery case chips from the soil and place them in your trash container (store your trash container
outside, not inside your house or garage, in a place where the trash will not be disturbed) until your
trash hauler picks up and transports your trash to an approved disposal facility; or
• If you find a large amount of battery case chips, do not disturb the battery case chips and soil, and
immediately call the Illinois EPA, Bureau of Land, or the Madison County Planning and Development
Department, Madison County Recycling (the telephone numbers are listed below) for help.
-------
Battery case chips, or excavated soil containing battery case chips, cannot be used as fill material at any other
property or disposed at any other location except in an approved, licensed disposal facility. After the battery case
chips and soil have been removed and if the hole is to be filled in, the excavated area should be filled with clean,
uncontaminated soil, followed by ground cover (sod, gravel, asphalt, or concrete).
SITE DESCRIPTION AND HISTORY
NL Industries operated a lead smelting and recycling plant at 16th Street and Cleveland Boulevard in Granite City,
Illinois, from 1903 until 1983. From the 1950's forward, the plant also recycled lead-acid batteries. According to
the U.S. Environmental Protection Agency (EPA), airborne lead particles from the smelter contaminated some
properties in Granite City, Madison, and Venice, and impacted other properties where lead-contaminated, battery
case chips were used to fill low-lying areas. From 1993 to 2000, the U.S. Army Corps of Engineers, EPA, and
private companies performed a cleanup at the plant and surrounding properties. Under EPA's approved cleanup
plan, some properties may still contain lead-contaminated soil and/or battery case chips. This information sheet is
to notify you that the property you plan to dig or excavate may be one of those properties and may contain lead-
contaminated soil or battery case chips.
LEAD USE AND POTENTIAL HAZARDS
Lead is also a naturally occurring element. It is a relatively soft, naturally occurring metal that can be found
almost anywhere. Much of the lead in the environment comes from human activities including burning fossil fuels
(for example, coal-fired power plants and gasoline in automobiles), mining, and manufacturing. Lead was used in
many materials and products (such as lead paint, lead solder, etc.) before the potential health risks were
discovered. Lead can be found at home, at schools and childcare facilities, in products, in drinking water, in
outdoor air and soil. Lead was the main ingredient in the batteries that were recycled by NL Industries at the
Granite City plant.
Adverse health effects can be associated with lead exposure and elevated levels of lead in the blood, particularly
in children under six years of age. You can get more information about the hazards and potential health effects of
lead by contacting the Madison County Lead Program at:

Re: NL Industries/Taracorp Superfund Site; Granite City, Illinois
Second 2023 Semi-Annual Operation and Maintenance Inspection (October 4, 2023)
and EPA Site Visit (October 5, 2023)
Dear Mr. Green:
On behalf of the NL Industries/Taracorp Superfund Site Group (Group), enclosed are copies of the
log sheets, aerial photographs, and ground-level photographs documenting the results from the
second 2023 semi-annual operation and maintenance inspection performed on October 4, 2023 at
the NL Industries/Taracorp Superfund Site in Granite City, Illinois.
The results of the semi-annual operation and maintenance inspection are summarized as follows:
¦ At Slough Road (shown on Figure 1 and the photographs in Attachment 1), no disturbance
of the gravel cover to the previously paved area (Slough Road) was observed. Beelman River
Terminals, Inc. is continuing to expand its operations to the south, beyond the paved surface
of Slough Road and toward Bremen Street.
¦ The paved portion of Watson Alley in Eagle Park Acres (Figure 2 and photographs 4-9 in
Attachment 2) and the vacant lot on Harrison Street (adjacent to the unpaved portion of
Watson Alley where scattered battery case chips were previously observed on the soil surface
after vegetation was cleared in 2019) was checked. No evidence of soil disturbance was
observed. The Harrison Street property (Figure 3 and photographs 7-9 in Attachment 3) is
covered with vegetation, which is periodically being mowed.
¦ Two remote fill properties (200 Allen Street and 206 Terry Street) in Eagle Park Acres
(Figure 3 and photographs 1-6 in Attachment 3) that were previously remediated by EPA
(and where lead-impacted soil and/or battery case chips may remain in place at depths of two
feet and three feet below the ground surface, respectively) were observed during the
inspection. No evidence of subsurface soil disturbance was observed. The properties are
lawn-covered and were recently mowed.
¦ Alleys in Venice that were paved during remedial activities were noted to be in generally
good condition. The Venice alleys are shown on Figure 1 and are identified on the
NL Industries/Taracorp Site O&M
20231012_Operation and Maintenance Inspection Report

photographs in Attachment 4. Some small asphalt patches were observed (Attachment 4,
photographs 11, 16, and 19, for example), confirming that the local municipality is
continuing to repair and repave alleys, as necessary. Some fencing (Attachment 4,
photograph 24) was observed on the paved surface of the alley near Madison Street in Venice,
which appeared to be related to construction work on the neighboring residential dwelling.
¦ At the main industrial site, including the Taracorp pile and 1555 State Streete properties
(Figure 4), the access gates were locked, the fences were secure, warning signs were securely
affixed to the fences, no evidence of soil disturbance was observed, and no problems were
identified with the storm water drainage and collection system around the Taracorp pile.
Several other observations and follow-up actions, based on the inspection, are summarized
as follows:
• The Group's lawn maintenance contractor, Munie Greencare Professionals (Munie), is
periodically cutting the vegetation along the 1555 State Street property and on the
Taracorp pile property. Munie is scheduled to cut the vegetation on the Taracorp pile
cap later this month.
• Munie recently filled groundhog holes in the Taracorp pile cap with topsoil. In
addition, Munie recently applied herbicide to control the growth of vegetation along
the sidewalk on the 1555 State Street property (Attachment 5, photographs 67-70 and
72-77).
• Based on the results of the inspection, the Group has requested that Munie: (1) remove
one woody bush (in the area shown on Figure 4A and Attachment 5, photograph 32)
from the western side of the Taracorp pile cap; and (2) apply herbicide to control the
growth of vegetation on the fence along the south side of the Taracorp pile cap (in the
areas shown on Figure 4A and Attachment 5, photographs 35-41).
• Several small cracked pieces of concrete were observed in the concrete surface water
drainage channel along the northwestern side of the Taracorp pile cap (Attachment 5,
photographs 16-18). However, no problems impacting the effectiveness of the concrete
surface water drainage channel around the Taracorp pile and the stormwater discharge
system were observed during the inspection.
• The Group's groundwater consultant, Environmental Works, Inc. (EWI) is currently
performing the groundwater sampling event in conjunction with EPA's five-year
review. Two portable tote containers (Attachment 5, photograph 64) containing
groundwater well purge water are temporarily stored on-site inside the gate on the 15 5 5
State Street property pending characterization and disposal.
• Since the time of the previous operation and maintenance inspection, the Group's
contractor, TNT Fence Company, has removed a 50-foot section of unused interior
fence (at the locations shown on photographs 57 and 60 in Attachment 5) and has
repaired several sections of fence fabric and several fence posts along the railroad
tracks (Attachment 5, photographs 58,59, and 86), and along the sidewalk (Attachment
5, photographs 62, 74, and 87).

¦ As shown on the photographs in Attachment 6, no evidence of disturbance of the soil cover
or asphalt roadway was observed at Schaeffer Road (a remote fill property remediated by
EPA). Some scattered battery case chips were observed on the ground surface near the
sanitary sewer manhole located near the western end of Schaeffer Road (at the approximate
location shown on Figure 5) and in a few small areas along Schaeffer Road. In addition, some
battery case chips were observed in the field along the stormwater drainage channel on the
western side of the property.
¦ At Sand Road (also a remote fill property remediated by EPA and shown on Figure 6), some
scattered battery case chips and other debris (concrete, bricks, wood, etc.) were observed on
the ground surface within the foundation area of the former building on the property and in
the surrounding field (Attachment 7).
The Group's project coordinator participated with EPA and Illinois EPA during EPA's five-year
review site visit on October 5, 2023. The following areas were visited during the five-year review
site visit: (1) main industrial site, including the 1555 State Street and Taracorp pile properties; (2)
several monitoring well locations on the 1555 State Street property, Mayco Illinois LLC property,
and 1460 State Street property; (3) remote fill properties in Eagle Park Acres; (4) Watson Alley in
Eagle Park Acres; (5) Venice alleys; (6) 1218 Madison Avenue property; (7) Sand Road property;
(8) Schaeffer Road properties; (9) Slough Road properties; and (10) several denied access
residential properties.
As indicated above, additional information documenting the results of the October 4, 2023
operation and maintenance inspection is attached.
Please let me know if you have questions or if additional information or clarification is needed at
this time.

Five-Year Review
2023 Groundwater Monitoring Report
NL Industries/Taracorp Superfund Site, Granite City, IL
November 2023
2.0 SITE BACKGROUND
The NL Industries/Taracorp Superfund Site is located in a heavily industrialized section of Granite City,
Illinois, a community of approximately 21,000 residents approximately 2 miles east of St. Louis, Missouri,
and the Mississippi River. Metal refining, fabricating, and associated activities were conducted at the Site
beginning before the turn of the twentieth century, with secondary lead smelting conducted since 1903.
Operations ceased at the Site in 1983. As a result of these historical operations, a few metal compounds,
including cadmium, lead, and zinc, have been detected in groundwater in the former lead-acid battery
breaking area. The main industrial site (Figure 1) where lead-acid battery breaking and secondary lead
reclamation operations were previously performed is located at the corner of 16th Street and Cleveland
Boulevard in Granite City.
The Site was added to the National Priorities List (NPL) in 1986 after the former owner of the Site, NL
Industries, Inc., voluntarily entered into an Agreement and Administrative Order by Consent with USEPA
and the Illinois Environmental Protection Agency (IEPA) to perform a Remedial Investigation/Feasibility
Study (RI/FS) in January 1987. The USEPA selected the remedy for the Site and issued a Record of
Decision (ROD) in March 1990 and a Unilateral Administrative Order (UAO) in November 1990.
In 1995, USEPA reopened the ROD for the Site and added a groundwater containment component to the
remedial remedies for the Site. Additional groundwater wells were installed in 2000, and additional
groundwater monitoring was performed and reported in the 2000 Pre-Design Investigation Report for
Groundwater (ARCADIS, 2000). The USEPA determined that:
• The extent of groundwater contamination at the Site was very limited;
• The extent of groundwater contamination would likely decrease even further in the future;
• There was no legitimate reason to require installation of a groundwater containment system at
the Site; and
• The groundwater remedy for the Site would consist of additional groundwater monitoring, with
development of a contingency plan to address any exceedances of groundwater standards in
the event they occur outside of the perimeter monitoring wells.
Based on the above conclusions, it was recommended that the groundwater remedy requirement be
modified to consist of groundwater monitoring only. The Group submitted a Groundwater Monitoring
Plan to the USEPA in December 2000, which was approved in August 2001. Annual groundwater
monitoring events were conducted in 2001, 2002, and 2003. Following completion of the 2003 annual
groundwater monitoring event, the Group submitted a letter to the USEPA in August 2003 which
recommended that:
• Future groundwater monitoring should be limited to the monitoring wells within the boundaries
of the Main Industrial Site shown in Figure 2;
• Off-site downgradient monitoring wells installed at the Granite City Steel facility and the
Terminal Railroad of St. Louis property should be eliminated from the future monitoring
program; and
• The remote fill area monitoring wells in Venice Township and Eagle Park Acres should also be
eliminated from the future monitoring program.

The USEPA approved these recommendations and determined that groundwater monitoring for the
remaining wells located at or near the Main Industrial Site should be conducted once every five years in
conjunction with the USEPA's Five-Year Reviews of the Site. Five-Year Review Groundwater Monitoring
has been conducted at the Site in January 2009, April 2014, November 2018, and September 2023, with
the following conclusions:
• Groundwater flows in a generally south-southwesterly direction within the uppermost aquifer
beneath the Main Industrial Site.
• Total and dissolved cadmium and zinc have been detected above groundwater performance
standards in monitoring wells GMMW-108S and GMMW-108D, which are located directly
downgradient from the former battery breaker. These compounds have been consistently
detected at these wells since 2000 but have had decreasing concentration trends since that
time. Cadmium and zinc concentrations in the monitoring wells further downgradient from the
source area were non-detect for these constituents, indicating that the dissolved phase
contamination is contained within the boundaries of the Main Industrial Site.
• Total lead has been detected at concentrations above the groundwater performance standard in
monitoring wells GMMW-107S and GMMW-105S. In 2009, it was concluded that the total lead
results were due to suspended sediment in samples and not attributable to the former source
area. Starting in 2014, both total (unfiltered) and dissolved (filtered) metals samples were taken
at each location. None of the samples have had detections of dissolved lead above the
groundwater performance standard.
Section 3.0 of this report addresses the September 2023 groundwater sampling activities in more detail.

3.0 SITE ACTIVITIES
The following work was performed or is scheduled to be performed by EWI on the Group's behalf as part
of the September 2023 Five-Year Review Groundwater Monitoring in accordance with the 2008 Scope of
Work and the 2023 QAPP:
• Assessment of the condition of the 15 existing groundwater monitoring wells at the Main
Industrial Site to determine whether any monitoring wells must be repaired or replaced;
• Redevelopment of the monitoring wells to remove suspended solids in preparation for
groundwater sampling activities;
• Collection and analysis of groundwater samples from the monitoring wells;
• Collection of water from the leachate collection sump of the closed Taracorp pile;
• Wastewater sample collection and analysis of purge water from the groundwater monitoring
activities and leachate sump collection for disposal into the sanitary sewer under authorization
from the Granite City Regional Wastewater Treatment Plant (GCRWWTP), pending approval of
laboratory analytical.
3.1 Monitoring Well Assessment and Redevelopment
On September 11, 2023, EWI conducted a visual assessment of the condition of the monitoring wells,
including the general state of the completion, security, the condition of the surface seal, and ease of
identification and access. The 15 existing monitoring wells assessed as part of the 2023 sampling event
are presented on the Site Diagram in Figure 2. GMMW-105S was removed from the sampling plan in
2018 after subsurface damage was encountered and was subsequently abandoned in August 2019 per
USEPA and IEPA approval. Based on the 2023 assessment, vegetation was cleared from MW-104,
GMMW-109S, GMMW-109D, GMMW-109X, GMMW- 112S, and GMMW-112D. Monitoring wells were
generally in good condition with satisfactory surface completions and clear identification markings, and
they remained padlocked and inaccessible to the general public.
Prior to redevelopment, the monitoring wells were opened, and groundwater levels were allowed to
equilibrate. The wells were then gauged with an electronic water level indicator to the nearest 0.01 foot
to determine depth to groundwater and total depth of the monitoring well. Table 1 provides a summary
of the monitoring well construction details, including groundwater elevations and total depths measured
during the September 2023 sampling event. A potentiometric surface diagram generated from the 2023
water level measurements is illustrated in Figure 3. The groundwater flow was generally to the south,
with an average hydraulic gradient of 0.002 feet per foot which is generally comparable to historic
results.
The monitoring wells were redeveloped on September 11th through 13th, 2023, prior to groundwater
sampling using a submersible groundwater pump. The wells were surged with the submersible pump
throughout development activities to suspend and recover sediments. During the redevelopment, water
quality parameters (pH, temperature, specific conductivity, turbidity, dissolved oxygen, and
oxidation/reduction potential [ORP]) were collected with a multi-parameter water quality meter equipped
with a flow-through cell. The field crew targeted removal often well volumes of water with stabilized
water quality parameters per the Scope of Work and QAPP. Well development logs are included in
Appendix C.

3.2 Groundwater Sampling
Groundwater samples were collected from 15 monitoring wells (Table 1) on September 14th and 15th,
2023. The monitoring wells were sampled using a peristaltic pump utilizing low-flow sampling procedures
outlined in the 2008 Scope of Work and 2023 QAPP to minimize drawdown in the well. Water quality
readings were recorded every five minutes using a multi-parameter water quality meter equipped with a
flow-through cell for pH, temperature, specific conductivity, turbidity, dissolved oxygen, and ORP.
Samples were collected when the water quality parameters and drawdown stabilization were achieved
with three successive readings, indicating that samples representative of the hydrogeologic unit were
collected. Because of previous analyte detections related to suspended sediment in the samples, both
filtered and unfiltered samples were collected, with filtration of unfiltered samples completed by the
analytical laboratory. Low-flow sampling logs are included in Appendix D.
Groundwater samples were submitted on ice under chain of custody protocol to Eurofins Laboratories of
University Park, Illinois (Eurofins) for analyses. All samples were analyzed for both total (unfiltered) and
dissolved (filtered) lead, cadmium, and zinc using USEPA Method SW 6010D. Two field duplicate samples
and two matrix spike/matrix spike duplicate (MS/MSD) samples were also submitted to the project
laboratory for quality control purposes.
3.3 Investigation Derived Waste, Leachate Recovery, and Disposal
Approximately 325 gallons of purge water were generated during the September 2023 groundwater
development and sampling activities. The water was containerized in two polyethylene totes and
temporarily stored inside the locked gate on the 1555 State Street property. A groundwater sample was
collected with a disposable poly bailer from the stagnant water in the leachate collection sump of the on-
site closed Taracorp waste pile and submitted to Eurofins for analysis of arsenic, barium, cadmium,
chromium, copper, iron, lead, manganese, nickel, selenium, silver, zinc, mercury, oil and grease,
cyanide, pH, phenols, total suspended solids, total dissolved solids, and biochemical oxygen demand.
Arsenic was reported at a concentration (0.77 mg/L), slightly above the GCRWWTP discharge limit (0.5
mg/L). The laboratory analytical data for the September waste characterization sample is included in
Appendix E. EWI removed leachate from the leachate collection sump of the closed Taracorp pile on
November 6, 2023, and temporarily staged the leachate in a polyethylene tote container inside the
locked gate on the 1555 State Street Property. Following completion of leachate removal activities, EWI
collected an additional composite sample for analysis and approval by GCRWWTP to discharge into the
Granite City sanitary sewer manhole located at the corner of 16th Street and Edison Avenue. The Group
will provide the laboratory report from analysis of the composite sample and will document the
completion of leachate disposal activities in a subsequent letter to USEPA upon completion of the work.

4.0 ANALYTICAL RESULTS
Table 2 presents a summary of the laboratory analytical results for groundwater samples collected as
part of the 2023 Five-Year Review Groundwater Monitoring event. Historical groundwater analytical
results from the March 2000, April 2000, December 2001, July 2002, March 2003, January 2009, April
2014, and November 2018 monitoring events are also included in Table 2 for reference. A copy of the
laboratory analytical report for the September 2023 monitoring event is included in Appendix E.
4.1 Groundwater Results
The groundwater analytical results were compared to the groundwater performance standards for the
Site, which are the USEPA maximum contaminant levels (MCLs) of 0.005 and 5.0 mg/L for cadmium and
zinc, respectively, and the USEPA action level of 0.015 mg/L for lead. The following performance
standard exceedances occurred:
• Consistent with previous results, GMMW-107D and GWMW-107S slightly exceeded the
performance standard for total lead (0.015 mg/L) at 0.017 and 0.019 mg/L, respectively;
however, dissolved lead was not detected.
• GMMW-108D slightly exceeded the performance standard for total lead; however, dissolved lead
was not detected. Consistent with previous results, GMMW-108D exceeded the performance
standards for total and dissolved cadmium and zinc. The concentrations of cadmium and zinc are
decreasing when compared to previous results.
• Consistent with previous results, GMMW-108S exceeded the performance standard for total and
dissolved cadmium; however, the cadmium concentrations are continuing to decrease when
compared to previous results. Also, notably, the zinc concentrations in GMMW-108S were below
the USEPA MCL for the first time since the Group commenced groundwater monitoring activities
in 2000.
Compounds detected above the associated performance standards during the September 2023 event are
consistent with historical analytical results. Based on a review of the 2023 data and comparison of total
and dissolved lead data, it is apparent that detections of total lead are a result of suspended sediment in
the samples rather than persistent dissolved-phase contamination from the former source area. GMMW-
108S and GMMW-108D, directly downgradient from the source area, have consistently had detections for
total and dissolved cadmium and zinc above the performance standards; however, the concentrations of
these compounds have had overall decreasing trends since the initiation of groundwater sampling
activities in 2000.
4.2 Data Validation
The Level II data package (Lab Project #500-239705-1) provided by Eurofins was reviewed in
accordance with the QAPP, EWI Standard Operating Procedures, and the guidelines presented in in the
USEPA National Functional Guidelines for Superfund Inorganic Methods Data Review (USEPA, 2017). The
conclusions of the data validation were that data are usable and meet project data quality objectives.
The data validation report is included as Appendix F.

2023 Groundwater Monitoring Report

November 2023
5.0 SUMMARY AND CONCLUSION
EWI conducted Five-Year Review Groundwater Monitoring activities at the NL Industries/Taracorp
Superfund Site in September 2023, including assessment, redevelopment, and sampling of the 15
existing monitoring wells at the Main Industrial Site, as well as recovery of leachate from the Taracorp
pile. Activities were conducted in accordance with the 2018 Scope of Work and 2023 QAPP. The
following is a summary of findings from this event:
• The existing monitoring well network is in good condition. Vegetation was removed around six
wells prior to sampling activities, and all monitoring wells remained padlocked and inaccessible
to the general public.
• The groundwater flow direction was to the south with a hydraulic gradient of 0.002 feet per
foot (ft/ft), generally similar to historical results; some groundwater gradient fluctuation is
expected due to proximity to the Mississippi River.
• The groundwater performance standard for total lead was exceeded in the unfiltered
groundwater samples collected from monitoring wells GMMW-107D, GMMW-107S, and GMMW-
108D; however, lead was non-detect in the filtered samples. This indicates the presence of lead
in these samples was due to suspended solids, not the dissolved phase contamination from the
source area at the Main Industrial Site.
• The groundwater performance standards for cadmium and zinc were exceeded in both the
filtered and unfiltered groundwater samples collected from GMMW-108D, located immediately
downgradient from the source area. These compounds have been detected above the
performance standards in this well since 2000 but have consistently decreased in concentration
since that time. GMMW-108S exceeded USEPA MCLs for cadmium; the zinc concentrations
decreased to levels below the MCL for the first time since the Group initiated groundwater
monitoring events in 2000.
• Cadmium and zinc concentrations in the monitoring wells further from the source area (MW-
101, MW-104, GMMW-105D, GMMW-107D, GMMW-107S GMMW-109S, GMMW-109X, GMMW-
112D, GMMW-112S, GMMW-113D, and GMMW-113S) were non-detect. Cross-gradient and up-
gradient monitoring wells were non-detect, indicating that the dissolved phase contamination is
limited to near the source area.
In conclusion, results from the September 2023 groundwater sampling event are consistent with
historical results and continue to support the conclusion that the remaining dissolved phase
contamination is limited to an area near the former battery breaker area within the boundary of the Main
Industrial Site. Concentration trends within the former battery breaker area have continued to decrease
over time, further indicating limited impact and no evidence of any contaminant migration.

RE: Quality Assurance Project Plan Amendments (July 2023) Five-Year Review
Groundwater Sampling Activities
NL Industries/Taracorp Superfund Site, Granite City, IL
Dear Mr. Leed:
The purpose of this letter is to present updated information relevant to Environmental Works, Inc. (EWI)
performing the five-year review groundwater monitoring at the NL Industries/Taracorp Superfund Site in
Granite City, IL (Site). EWI will perform the work on behalf of the NL Industries/Taracorp Superfund Site
Group (The Group) in accordance with the EPA-approved Quality Assurance Project Plan (QAPP) dated
September 1999, with the following modifications:
Scope of Work
Work performed by EWI will be completed in a manner consistent with the Scope of Work Groundwater
Monitoring for Five- Year Review and tasks 1-5 defined in the 2023 transmittal letter from The Group's
project coordinator to the United States Environmental Protection Agency (USEPA). Language regarding
the scope of work in these documents supersedes references to the "Pre-Design Investigation" found
throughout the 1999 QAPP. The previous groundwater sampling event completed by EWI in 2018
included low-flow purging and sample collection of 16 monitoring wells. Per the approval of the USEPA
and Missouri Department of Natural Resources (MoDNR), MW-105S was abandoned during the 2018
sampling efforts due to previous damage in the well, as detailed in the Monitoring WellMW-105S Well
Abandonment Activities report submitted October 3, 2019. Therefore, the 2023 scope of work will
include 15 monitoring wells.
Approval Sheet
An approval sheet signed by pertinent project personnel documenting that EWI will abide by the
procedures outlined in the QAPP, as modified by this letter update, isattached.
Project Roles
An updated project organization chart is attached and reflects the following changes:
• Responsibility for project management of this work lies with the EWI Project Manager - Kristin
Heideman, 314-605-8179.
• Responsibility for all quality assurance/quality control review lies with the EWI Quality Assurance
Manager - Anthony Moore, 413-773-5747.

• Field work will be completed by a crew of EWI Associate Scientists. Prior to mobilizing to the Site,
one Associate Scientist will be appointed by the EWI Project Manager to fill the Field Geologist,
Equipment Manager, and Site Safety Officer roles outlined within the QAPP.
• Laboratory chemical analyses will be performed by Eurofins Environmental Testing. The Eurofins
project manager for this work is Donna Campbell.
Laboratory Analytical Limits
Updated laboratory data quality information including method detection limits, reporting limits, sample
bottles and preservatives, and hold times relevant to this scope of work is attached.
Water Quality Monitoring
A Yellow Springs Instrument (YSI) ProDSS unit and flow-through cell or similar water quality meter will
be used to monitor groundwater quality parameters during sampling activities. This is a newer model of
the device specified in the QAPP.
If you have any questions about these modifications to the QAPP, please feel free to contact me at
314-605-8179.
Sincerely,

Hi, Aaron:
Do you think you will soon be able to provide an authorization for the Group to proceed with groundwater monitoring at
the NL/Taracorp Site? I'm concerned that we may not be able to complete the work in time to have the data for your
five-year review report.
Thanks.

Receipt
The samples were received on 9/16/2023 10:20 AM. Unless otherwise noted below, the samples arrived in good condition, and where
required, properly preserved and on ice. The temperatures of the 2 coolers at receipt time were 0.1° C and 1.6° C.
Metals
Method 6010D: The initial low level calibration verification (ICVL) result for batch 733155 was above the upper control limit forAg, Pb, and
Se. Sample results were all below the reporting limit and have been reported as qualified data.
Method 6010D: The initial low level calibration verification (ICVL) result for batch 733155 was below the lower 70-130% control limit for Fe.
The low level standard concentration was insignificant compared with the reported results and sample results were unaffected by the low
bias at that level. The mid range CCV's bracketing the data were all within the 90-110% control limits. Samples have been reported as
qualified data.
Method 6010D: The method blank for preparation batch 732728 contained Se above the reporting limit (RL). None of the samples
associated with this method blank contained the target compound; therefore, re-extraction and/or re-analysis of samples were not
performed
Method 6010D: The initial calibration verification (ICV) result for batch 734883 was above the 90-110% upper control limit for Zn (111%). All
batch QC and bracketing CCV were within control limits and sample results were not affected by the slight bias at that level. Samples have
been reported as qualified data.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
General Chemistry
Method SM 5210B: The glucose-glutamic acid standard (LCS) recovered outside the recovery limits specified in the method in batch
500-733353. The method holding time had expired, therefore the analysis was not repeated. The data was qualified and reported.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

and have been reported as qualified data.
• Method 6010D: The initial low level calibration verification (ICVL) result for batch 733155 was
below the lower 70-130% control limit for Fe. The low level standard concentration was
insignificant compared with the reported results and sample results were unaffected by the low
bias at that level. The mid range CCV's bracketing the data were all within the 90-110% control
limits. Samples have been reported as qualified data.

• Method 6010D: The initial calibration verification (ICV) result for batch 734883 was above the 90-
110% upper control limit for Zn (111%). All batch QC and bracketing CCV were within control
limits and sample results were not affected by the slight bias at that level. Samples have been
reported as qualified data.
5.0 Method Blanks
Method blanks samples are prepared and analyzed to determine the existence and magnitude of
contamination resulting from laboratory sample preparation activities, ambient laboratory conditions, and
background contamination within the analytical equipment.
The method blank for preparation batch 732728 contained Se above the reporting limit (RL). None of the
samples associated with this method blank contained the target compound; therefore, re-extraction
and/or re-analysis of samples were not performed.
6.0 Laboratory Control Sample (LCS)
The LCS serves as an indicator of the laboratory's data accuracy, independent of sample matrix
interferences. Samples are spiked with known amounts of analytes then analyzed using method 6010D.
The analytes must be recovered between the control limits of 80% and 120%. LCS were prepared and
analyzed at the proper frequency.
The glucose-glutamic acid standard (LCS) recovered outside the recovery limits specified in the method
in batch 500-733353. The method holding time had expired, therefore the analysis was not repeated.
The data was qualified and reported.
7.0 Matrix Spike/Matrix Spike Duplicate (MS/MSD)
MS/MSD analyses are used to provide information about the effect of the sample matrix (groundwater)
on the accuracy and precision of the analytical data. Sample volume from GW-MW104-091423 and GW-
GMMW105D-091523 was utilized for the MS/MSD analyses. These samples were spiked with known
amounts of analytes then analyzed using method 6010D. The MS/MSD percent recoveries and the
relative percent differences (RPDs) for the duplicate analyses were within the laboratory's acceptance
ranges.
8.0 Field Duplicate
Field duplicate sample analysis is used to assess the precision of the field sampling procedures and the
precision of the laboratory's analyses. Blind duplicate samples were submitted to the laboratory for GW-
MW101-091423 and GW-GMMW113D-091523. The field duplicate samples results are summarized
below:

The duplicate sample GW-DUP1-091423, a duplicate of MW-101, reported a total lead result at 0.013 mg/L,
but the dissolved lead analysis was non-detect. Therefore, this likely indicates that the lead detection
was a result of suspended solids in the sample, per historical data at the Site.
9.0 Analyte Identification and Quantification
All reporting limits met with project data quality objectives and specifications.
10.0 Conclusion
Based on this data validation, all data are useable and meet project data quality objectives.

Re: NL Industries/Taracorp Superfund Site; Granite City, Illinois
2023 Groundwater Monitoring Report / Leachate Management
Dear Mr. Green:
As you know, the NL Industries/Taracorp Superfund Site Group (Group) submitted a
document, titled Five-Year Review 2023 Groundwater Monitoring Report, to the U.S.
Environmental Protection Agency (EPA) in November 2023. The report, which was prepared
by the Group's consultant, Environmental Works, Inc. (EWI), documented the results of the
2023 groundwater monitoring event at the NL Industries/Taracorp Superfund Site (site) and
summarized the work that had been performed related to the leachate within the closed
Taracorp pile.
As indicated in the Five-Year Review 2023 Groundwater Monitoring Report, EWI collected
a groundwater sample with a disposable poly bailer in September 2023 from the stagnant
water in the leachate collection sump of the closed Taracorp waste pile and submitted the
sample to Eurofins Environment Testing (Eurofins) for analysis of arsenic, barium, cadmium,
chromium, copper, iron, lead, manganese, nickel, selenium, silver, zinc, mercury, oil and
grease, cyanide, pH, phenols, total suspended solids, total dissolved solids, and biochemical
oxygen demand. As indicated in the laboratory analytical report (Appendix 1), arsenic was
reported at a concentration of 0.77 mg/1, which was slightly above the Granite City Regional
Wastewater Treatment Plant's discharge limit (0.5 mg/1).
On November 6, 2023, EWI removed leachate from the leachate collection sump,
temporarily staged the leachate in a polyethylene tote container inside the locked gate on the
1555 State Street property, and collected a composite sample for laboratory analysis. The
laboratory data from the analysis of the November 6, 2023 composite sample, which met the
local requirements for discharge into the sanitary sewer, are provided in Attachment 2.
Therefore, EWI submitted a letter (Appendix 3) to the Granite City Regional Wastewater
Treatment Plant and received approval (Appendix 4) on November 29, 2023 to discharge the
leachate and groundwater monitoring well purge water into the sanitary sewer. Based upon
the Granite City Regional Wastewater Treatment Plant's approval, EWI worked on-site on
November 30, 2023 and discharged the water into the sanitary sewer manhole located near
16th Street and Edison Avenue in Granite City.

Receipt
The sample was received on 11/7/2023 9:35 AM. Unless otherwise noted below, the sample arrived in good condition, and where
required, properly preserved and on ice. The temperature of the cooler at receipt was -1.0° C.
Metals
Method 6010D: The initial low level calibration verification (ICVL) result for batch 742620 was above the upper control limit for Pb. Sample
results were non-detects, and have been reported as qualified data.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
General Chemistry
Method SM 5210B: The glucose-glutamic acid standard (LCS) recovered outside the recovery limits specified in the method in batch
500-742068. The method holding time had expired, therefore the analysis was not repeated. The data was qualified and reported.
Method SM 5210B: The method blank result associated with batch 500-742068 was 0 63 mg/L which is higher than the method-required
limit of 0 2 mg/L. The data was qualified and reported.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

RE: Request to Discharge Groundwater
NL Industries/Taracorp Superfund Site
16th & State Streets
Granite City, IL
Dear Mr. Selph:
Environmental Works, Inc. (EWI) has been hired by Montrose Environmental to oversee the five-year
groundwater sampling activities and manage associated wastewater disposal for the NL
Industries/Taracorp Superfund Site in Granite City, Illinois (Site). EWI again requests approval to
discharge groundwater collected from monitoring wells and the leachate collection system on the
property at 16th & State Street in Granite City.
Similar to the approved discharge for activities that occurred during the last event in 2018,
approximately 800 gallons of groundwater from monitoring wells on-site as well as the leachate
collections system will be transferred from on-site poly tanks currently temporarily staged at the Site into
the sanitary sewer manhole located near the corner of 16th Street and Edison Avenue. The laboratory
analytical report for the composite waste sample, as well as the Industrial Discharge Self-Monitoring
Report are included as attachments.
Should you have any questions regarding this letter, please feel free to contact me at 314-605-8179 or
by email at kheideman@environmentalworks.com.
Sincerely,
ENVIRONMENTAL WORKS, INC.

Receipt
The sample was received on 11/7/2023 9:35 AM. Unless otherwise noted below, the sample arrived in good condition, and where
required, properly preserved and on ice. The temperature of the cooler at receipt was -1.0° C.
Metals
Method 6010D: The initial low level calibration verification (ICVL) result for batch 742620 was above the upper control limit for Pb. Sample
results were non-detects, and have been reported as qualified data.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
General Chemistry
Method SM 5210B: The glucose-glutamic acid standard (LCS) recovered outside the recovery limits specified in the method in batch
500-742068. The method holding time had expired, therefore the analysis was not repeated. The data was qualified and reported.
Method SM 5210B: The method blank result associated with batch 500-742068 was 0 63 mg/L which is higher than the method-required
limit of 0 2 mg/L. The data was qualified and reported.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

contaminants appear stable with decreasing concentations.
X. Oil IKU KIM IM)I I S
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. OVKKAM, 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.).
Landfill remedy is effective in controlling exposure through direct contact and air borne dust.
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.
The PRP group is effectively maintaining cap and perimeter fence. Applications of herbicide is used to
control vegetation along fence. No issues were observed.
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.
No issues were observed. However to be effective, the cap and perimeter fence will need to be maintained
in perpetuity.
4. Early Indicators of Potential Remedy Problems
Describe possible opportunities for optimization in monitoring tasks or the operation of the remedy.
As noted in past FYRs and this current FYR, instutional controls (ICs) are needed to address site property,
other industrial properties, and potential excavation worker exposure.
