National Oil and Hazardous 

Substances Pollution Contingency 

Plan; National Priorities List: Partial 

Deletion of the Beloit Corporation 

Superfund Site 

AGENCY: Environmental Protection 

Agency. 

ACTION: Direct final rule. 

SUMMARY: The Environmental Protection 

Agency (EPA) Region 5 is publishing a 

direct final Notice of Deletion of the 

Research Center Property (RCP) of the 

Beloit Corporation Superfund Site 

(Site), in Rockton, Illinois from the 

National Priorities List (NPL). This 

partial deletion includes all media at the 

20-acre RCP. The rest of the Site 

remains on the NPL and is not affected 

by this action. The NPL, promulgated 

pursuant to Section 105 of the 

Comprehensive Environmental 

Response, Compensation, and Liability 

Act (CERCLA) of 1980, as amended, is 

an appendix of the National Oil and 

Hazardous Substances Pollution 

Contingency Plan. EPA is publishing 

this direct final partial deletion with the 

concurrence of the State of Illinois 

because all appropriate response actions 

at the RCP under CERCLA have been 

completed, other than maintenance, 

monitoring and five-year reviews. 

However, this partial deletion does not 

preclude future actions under 

Superfund. 

DATES: This direct final partial deletion 

is effective September 14, 2018 unless 

EPA receives adverse comments by 

August 15, 2018. If adverse comments 

are received, will publish a timely 

withdrawal of the direct final partial 

deletion in the Federal Register 

informing the public that the partial 

deletion will not take effect.

V. Partial Deletion Action 

I. Introduction 

EPA Region 5 is publishing this direct 

final Notice of Partial Deletion for the 

Beloit Corporation (Beloit Corp.) Site 

(Site), from the National Priorities List 

(NPL). This partial deletion pertains to 

the Former Beloit Corp. Research Center 

Property portion of the Site, PIN 03–12– 

452–003, located at 1155 Prairie Hill 

Road, Rockton, Illinois. The NPL 

constitutes Appendix B of 40 CFR. Part 

300 which is the National Oil and 

Hazardous Substances Pollution 

Contingency Plan (NCP), which EPA 

promulgated pursuant to Section 105 of 

the Comprehensive Environmental 

Response, Compensation and Liability 

Act (CERCLA) of 1980, as amended. 

EPA maintains the NPL as the list of 

sites that appear to present a significant 

risk to public health, welfare, or the 

environment. Sites on the NPL may be 

the subject of remedial actions financed 

by the Hazardous Substance Superfund 

(Fund). This partial deletion of the 

Beloit Corp. Site is proposed in 

accordance with 40 CFR 300.425(e) and 

is consistent with the Notice of Policy 

Change: Partial Deletion of Sites Listed 

on the National Priorities List. 60 FR 

55466 (Nov. 1, 1995). As described in 

§ 300.425(e)(3) of the NCP, a portion of 

a site deleted from the NPL remains 

eligible for Fund-financed remedial 

action if future conditions warrant such 

actions. 

Section II of this document explains 

the criteria for deleting sites from the 

NPL. Section III discusses the 

procedures that EPA is using for this 

action. Section IV discusses the Former 

Beloit Corp. Research Center Property, 

PIN 03–12–452–003 of the Beloit Corp. 

Superfund Site and demonstrates how it 

meets the deletion criteria. Section V 

discusses EPA’s action to partially 

delete this portion of the Site from the 

NPL unless adverse comments are 

received during the public comment 

period. 

II. NPL Deletion Criteria 

The NCP establishes the criteria that 

EPA uses to delete sites from the NPL. 

In accordance with 40 CFR 300.425(e), 

sites may be deleted from the NPL 

where no further response is 

appropriate. In making such a 

determination pursuant to 40 CFR 

300.425(e), EPA will consider, in 

consultation with the State, whether any 

of the following criteria have been met: 

i. Responsible parties or other persons 

have implemented all appropriate 

response actions required, 

ii. All appropriate Fund-financed 

response under CERCLA has been 

implemented, and no further response 

action by responsible parties is 

appropriate; or 

iii. The remedial investigation has 

shown that the release poses no 

significant threat to public health or the 

environment and, therefore, the taking 

of remedial measures is not appropriate. 

Pursuant to CERCLA Section 121(c) 

and the NCP, EPA conducts five-year 

reviews to ensure the continued 

protectiveness of remedial actions 

where hazardous substances, pollutants, 

or contaminants remain at a site above 

levels that allow for unlimited use and 

unrestricted exposure. EPA conducts 

such five-year reviews even if a site is 

deleted from the NPL. EPA may initiate 

further action to ensure continued 

protectiveness at a deleted site if new 

information becomes available that 

indicates it is appropriate. Whenever 

there is a significant release from a site 

deleted from the NPL, the deleted site 

may be restored to the NPL without 

application of the hazard ranking 

system. 

III. Partial Deletion Procedures 

The following procedures apply to the 

deletion of the Former Beloit Corp. 

Research Center Property, PIN 03–12– 

452–003 of the Beloit Corp. Site: 

(1) EPA has consulted with the State 

of Illinois prior to developing this direct 

final Notice of Partial Deletion and the 

Notice of Intent for Partial Deletion 

published in the ‘‘Proposed Rules’’ 

section of the Federal Register. 

(2) EPA has provided the State thirty 

(30) working days for review of this 

action and the parallel Notice of Intent 

for Partial Deletion prior to their 

publication today, and the State, 

through the Illinois Environmental 

Protection Agency (IEPA), has 

concurred on the partial deletion of the 

Site from the NPL. 

(3) Concurrent with the publication of 

this direct final Notice of Partial 

Deletion, a notice of the availability of 

the parallel Notice of Intent for Partial 

Deletion is being published in two 

major local newspapers, the Rockton 

Herald and the Rockford Register Star. 

The newspaper notices announce the 

30-day public comment period 

concerning the Notice of Intent for 

Partial Deletion of the Site from the 

NPL. 

(4) EPA placed copies of documents 

supporting the partial deletion in the 

deletion docket and made these items 

available for public inspection and 

copying at the Site information 

repositories identified in the ADDRESSES

Section of this rule. 

(5) If adverse comments are received 

within the 30-day public comment 

period on this partial deletion action, 

EPA will publish a timely notice of 

withdrawal of this direct final Notice of 

Partial Deletion in the Federal Register 

before its effective date and will prepare 

a response to comments and continue 

with the deletion process on the basis of 

the Notice of Intent for Partial Deletion 

and the comments already received. 

Deletion of a portion of a site from the 

NPL does not itself create, alter, or 

revoke any individual’s rights or 

obligations. Deletion of a portion of a 

site from the NPL does not in any way 

alter EPA’s right to take enforcement 

actions, as appropriate. The NPL is 

designed primarily for informational 

purposes and to assist EPA 

management. Section 300.425(e)(3) of 


sradovich on DSK3GMQ082PROD with RULES
32800 Federal Register / Vol. 83, No. 136 / Monday, July 16, 2018 / Rules and Regulations 

the NCP states that the deletion of a site 

from the NPL does not preclude 

eligibility for further response actions, 

should future conditions warrant such 

actions. 

IV. Basis for Partial Site Deletion 

The following information provides 

EPA’s rationale for deleting the Former 

Beloit Corp. Research Center Property, 

PIN 03–12–452–003, of the Beloit Corp. 

Site from the NPL: 

Site Background and History 

The Beloit Corp. Site (CERCLIS ID 

ILD021440375) is located in Rockton, 

Winnebago County, Illinois. The Site 

consists of one, site-wide operable unit. 

The Site includes the approximately 

200-acre former Beloit Corp. property 

and additional adjacent areas, including 

the Blackhawk Acres residential 

subdivision, and other industrial 

properties adjacent to the subdivision, 

including the former Soterion/United 

Recovery facility, a portion of the 

Taylor, Inc. property and the Safe-TWay property. The Site is bound on the 

north by Prairie Hill Road, on the west 

by the Rock River, on the south by a line 

projected from the Rock River along the 

south edge of a Village of Rockton 

easement and access road to Blackhawk 

Boulevard, and on the east by 

Blackhawk Boulevard. See Figures 1 

and 2 in Maps—Beloit Corp. Site and 

Area for Partial Deletion, Docket 

Document ID No. EPA–HQ–SFUND– 

1990–0011–0286 in the Docket. 

The Beloit Corp. used approximately 

20 acres of its 200-acre property for a 

research center (the Former Beloit Corp. 

Research Center Property), and 55 acres 

for a manufacturing plant, a wastewater 

treatment plant and lagoons, a gravel 

pit, and parking and outdoor storage 

areas. The Beloit Corp. used about 39 

acres of open field south of its 

manufacturing and storage areas for 

foundry sand disposal and fibrous 

sludge spreading. About 86 heavily 

wooded acres of the Beloit Corp. 

property located west and south of the 

operations areas remain vacant and are 

within a backwater and floodplain area 

of the Rock River. 

The Beloit Corp. property is divided 

into several parcels of land and has been 

redeveloped. The northern parcel of the 

Site is the location of the Former Beloit 

Corp. Research Center, PIN 03–12–452– 

003, and is the property EPA is deleting 

from the Site (see Property Map for 03– 

12–452–003 in Maps—Beloit Corp. Site 

and Area for Partial Deletion, Docket 

Document ID EPA–HQ–SFUND–1990– 

0011–0286 in the Docket). This property 

is approximately 20.757 acres and is 

owned by the Rock River Land 

Development Company (Rock River). 

The address for this property is 1155 

Prairie Hill Road, Rockton, Illinois. The 

property is zoned for heavy industrial 

use and is occupied by Andritz 

Paperchine, a supplier of papermaking 

technology. 

The remaining western and southern 

parcels of the former Beloit Corp. 

property are owned by Lubrizol 

Holding, Inc. (Lubrizol) and are not 

being deleted as part of this action. 

These parcels include the locations of 

the former Beloit Corp. manufacturing 

building, the former Beloit Corp. 

wastewater treatment plant and lagoons, 

the vacant fields, woods and floodplain 

areas, EPA’s groundwater extraction and 

treatment system cleanup remedy, and 

the majority of EPA’s groundwater 

monitoring well network (former Beloit 

Corp. Manufacturing Property). The 

PINs for these properties are 03–13– 

201–002, 03–12–452–002, 03–12–376– 

001, 03–13–126–001, 03–13–176–004. 

These parcels are also zoned for heavy 

industrial use. This part of the Site is 

occupied by Chemtool Inc. (Chemtool) 

and is used to manufacture specialized 

industrial lubricants. The address for 

the portion of the Site remaining on the 

NPL is 1165 Prairie Hill Road, Rockton, 

Illinois. 

The Beloit Corp. property was 

farmland until Beloit Corp. purchased it 

in 1957. The property has been used for 

industrial purposes since 1957. Beloit 

Corp. manufactured machines at the 

Site that produced layered paper 

products from paper pulp. Beloit Corp. 

used solvents at its plant for parts 

cleaning operations. Beloit Corp. used 

petroleum-based, non-chlorinated 

solvents until the mid-1970s, and 

chlorinated solvents from the mid-1970s 

until 1983. The exact composition of the 

chlorinated solvents and the amounts 

Beloit Corp. used are unknown. Beloit 

Corp. used mineral spirits for metal 

degreasing and parts cleaning from 1983 

until the facility closed in 1999. 

IEPA began investigating potential 

contamination on the Beloit Corp. 

property and in the surrounding area in 

the 1980s. In 1986, IEPA sampled 

residential wells in the Blackhawk 

Acres subdivision adjacent to the Beloit 

Corp. facility. Sixteen of the 55 private 

drinking water wells that were sampled 

were contaminated. 

IEPA’s investigations determined that 

the most likely source of the 

groundwater contamination in the 

Blackhawk Acres subdivision was the 

Beloit Corp. EPA proposed the Beloit 

Corp. property and the surrounding area 

to the NPL as the Beloit Corp. 

Superfund Site on June 24, 1988 (53 FR 

23988). EPA finalized listing the Beloit 

Corp. Site on the NPL on August 30, 

1990 (55 FR 35502). 

Beloit Corp. entered into a Consent 

Decree with IEPA in 1991 to conduct a 

Remedial Investigation (RI) and 

Feasibility Study (FS) at the Site. The RI 

found that the groundwater is 

contaminated with volatile organic 

compounds (VOCs) including 

tetrachloroethene (PCE), 1,1,1- 

tricloroethane (1,1,1-TCA), and 

trichloroethene (TCE). 

In 1993, IEPA determined that three 

residential wells in the Blackhawk 

Acres subdivision contained TCE in 

groundwater above the Maximum 

Contaminant Level (MCL) established 

under the Safe Drinking Water Act. 

IEPA subsequently fitted these three 

residential wells contaminated above 

the MCL with carbon filtration systems 

plus IEPA fitted a fourth residential well 

with a carbon filtration system. The 

filtration systems continue to be 

maintained by IEPA. In 1999, IEPA 

connected a fifth residence with 

contaminated well water to the Rockton 

municipal water supply when the 

contamination was discovered in 1998. 

The highest area of groundwater 

contamination is located under the 

southern area of the Erection Bay 

section of the Beloit Corp. 

manufacturing building. The primary 

groundwater contaminant in this area is 

PCE. The PCE contamination is believed 

to be due to the discharge of VOCs to 

the ground surface before Beloit Corp. 

constructed the Erection Bay over this 

area in 1989. The groundwater 

contamination is in the upper aquifer 

and generally flows from north to south. 

The groundwater contamination does 

not impact the Former Beloit Corp. 

Research Center Property, which is 

upgradient of the contaminant plume 

and EPA is deleting from the NPL in 

this action. 

IEPA issued an Action Memorandum 

to Beloit Corp. in 1996 to implement an 

Interim Source Control Action (ISCA) at 

the Site. The Action Memorandum 

required immediate measures to control 

the high levels of VOC groundwater 

contamination near the Beloit Corp. 

manufacturing building. 

Beloit Corp. conducted an 

Engineering Evaluation/Cost Analysis 

(EE/CA) to evaluate potential ISCA 

alternatives. The non-time critical 

removal action objectives developed in 

the EE/CA were to: Limit the potential 

for the migration of VOCs in 

groundwater at the Site through the 

installation of a groundwater 

containment system; initiate the 

removal of VOCs from the groundwater 

at the source area (the vicinity of the 

Erection Bay and groundwater 


sradovich on DSK3GMQ082PROD with RULES
Federal Register / Vol. 83, No. 136 / Monday, July 16, 2018 / Rules and Regulations 32801 

monitoring well W23); install and 

operate an appropriate treatment system 

for groundwater generated by the 

containment system to limit 

unacceptable discharges or emissions; 

and dispose of waste streams from the 

action. 

IEPA selected a groundwater pump 

and treat system as the ISCA. Beloit 

Corp. developed a Removal Action 

Design Report and constructed the 

groundwater extraction and treatment 

system in 1996. The pump and treat 

system consists of four extraction wells 

and an air stripper tower adjacent to the 

southwest corner of the Beloit Corp. 

manufacturing building on PIN 03–13– 

201–002. This system is currently 

operated by IEPA. The treated 

groundwater is discharged to the Rock 

River at an outfall located on Beloit 

Corp.’s former wastewater treatment 

plant and lagoons property, PIN 03–12– 

452–002, under a National Pollutant 

Discharge Elimination System (NPDES) 

permit. 

Beloit Corp. filed for bankruptcy in 

1999. As part of the bankruptcy, the 

court entered an order which, among 

other things, transferred the ownership 

of Beloit Corp.’s assets and liabilities, 

including the Beloit Corp. property, to 

the Beloit Liquidating Trust (the Trust). 

The ownership of the Beloit Corp. 

property then transferred to Giuffre II, 

LLC (Giuffre). The United States and 

Giuffre signed a settlement agreement in 

February 2002 under section 122(h) of 

CERCLA (the section 122(h) 

Agreement). The State of Illinois was 

also a party to the settlement agreement. 

The State of Illinois signed the 

agreement in April 2002. 

The section 122(h) Agreement settled 

and resolved the potential liability of 

Giuffre resulting from its ownership 

and/or operation of the Beloit Corp. 

property. The purpose of the section 

122(h) Agreement was to facilitate the 

cleanup of the Site and the reuse of the 

property. 

On March 18, 2003, Giuffre sold the 

Former Beloit Corp. Research Center 

Property portion of the Site (the part of 

the Site being deleted as part of this 

action, outside the area of groundwater 

contamination) to PPC Investment 

Group LLC (PPC). PPC leased the 

property to Paperchine. PPC sold the 

Former Beloit Corp. Research Center 

Property to Rock River on January 5, 

2015. Rock River continues to lease the 

Property to Paperchine (now known as 

Andritz Paperchine). 

Giuffre deeded the remaining areas of 

the former Beloit Corp. property (i.e., 

the Former Beloit Corp. manufacturing 

building, former wastewater treatment 

plant and lagoons, parking and storage 

areas and vacant/floodplain areas) to 

Rock River on January 31, 2008. Rock 

River subsequently leased this property 

to Chemtool. Lubrizol acquired 

Chemtool and purchased the remaining 

former Beloit Corp. property on August 

30, 2013. Lubrizol continues to operate 

at the Site as Chemtool. 

This partial deletion pertains to all 

media at the approximately 20.757-acre 

Former Beloit Corp. Research Center 

Property portion of the Beloit Corp. Site, 

PIN 03–12–452–003, located at 1155 

Prairie Hill Road, Rockton, Illinois (see 

Property Map for 03–12–452–003 in 

Maps—Beloit Corp. Site and Area for 

Partial Deletion, Docket Document ID 

EPA–HQ–SFUND–1990–0011–0286 in 

the Docket). 

Remedial Investigation and Feasibility 

Study (RI/FS) 

Beloit Corp. conducted the RI in four 

phases between 1992 and 1998. The 

Phase I and II investigations identified 

and investigated the source area(s) of 

the VOCs at the Site. The Phase III 

investigation determined the extent of 

the VOC groundwater contamination. 

The Phase IV investigation evaluated 

potential sources of a deeper TCE 

contaminant plume in the upper aquifer 

in wells in the southern portion of the 

Beloit property, the southern Blackhawk 

Acres subdivision and in the Village of 

Rockton. The Phase IV investigation 

also evaluated whether VOCs detected 

at a home in the Blackhawk Acres 

subdivision were migrating from an 

upgradient source area, and determined 

what effect the ISCA pump and treat 

system was having on groundwater in 

the southern portion of the Blackhawk 

Acres subdivision. 

The RI investigated the former Beloit 

Corp. foundry sand disposal area, 

former on-Site wastewater treatment 

plant (WWTP) lagoons, fibrous sludge 

spreading area where sludge from 

WWTP lagoons was applied, storage 

yard area, Erection Bay, chip pad, 

former dry well, welding area, loading 

dock, paint room, a nearby gravel pit, 

the Blackhawk Acres subdivision, the 

Rock River and the wetlands west of the 

Beloit Corp. operations areas, Rockton 

Excavating’s property, the Village of 

Rockton, and the Soterion property. 

The RI determined that the primary 

groundwater contamination at the Site 

originates under the southern area of the 

Erection Bay section of the Beloit Corp. 

manufacturing building. This area is 

located on PIN 03–13–201–002 within 

the Former Beloit Corp. Manufacturing 

Property, not the Former Beloit Corp. 

Research Center Property. The 

groundwater contamination is located in 

the shallow zone of the upper aquifer, 

from the water table, which is about 20 

feet below ground surface (ft-bgs), to a 

depth of approximately 60 ft-bgs. The 

groundwater contamination flows 

generally from north to south, off-Site 

and away from the Former Beloit Corp. 

Research Center Property. 

The groundwater contamination is 

believed to be due to the discharge of 

VOCs to the ground surface in this area 

before Beloit Corp. constructed the 

Erection Bay over this location in 1989. 

Soil and soil gas sampling in this area 

during the RI and during an additional 

Source Area Investigation in 2007, 

however, could not find any significant 

residual levels of VOCs in any 

unsaturated soil at the Site, including 

below the floor of the Erection Bay 

building. 

The RI found a plume of deeper 

groundwater contamination at the Site 

in the upper aquifer near the southeast 

corner of the Former Beloit Corp. 

Manufacturing Property. This 

groundwater contamination also flows 

off-Site, towards Rockton and the Rock 

River. This groundwater contamination 

is also downgradient of, and flows away 

from the Former Beloit Corp. Research 

Center Property. 

The groundwater in the deeper plume 

is contaminated primarily with TCE and 

is found at a depth of approximately 70 

ft-bgs. The source of the deeper, TCE 

Plume could not be located, but is 

believed to be in the vicinity of 

groundwater monitoring wells W26C 

and W18, near the southeast corner of 

the Former Beloit Corp. Manufacturing 

Property and the northwest corner of the 

Soterion facility. Extensive sampling of 

the soils and groundwater in these areas 

did not indicate the presence of residual 

TCE in the soils. The groundwater data 

however, provides evidence that a 

historical release of TCE occurred in 

this area, even though the source has 

since dissipated. 

The only structure on the Former 

Beloit Corp. Research Center Property 

(the part of the Site that is being 

deleted) that was operated by Beloit 

Corp. was its research center. Beloit 

Corp. built the research center in 1960 

and used the building to design and 

demonstrate its papermaking machines. 

Beloit Corp. conducted a Feasibility 

Study (FS) to evaluate cleanup 

alternatives to address the groundwater 

contamination at the Site. The FS did 

not develop cleanup alternatives to 

address other Site media because the 

baseline risk assessment did not identify 

any unacceptable risks associated with 

exposure to the other media including 

surface and subsurface soil, dust, vapor, 

surface water or sediment.

32802 Federal Register / Vol. 83, No. 136 / Monday, July 16, 2018 / Rules and Regulations 

Selected Remedy 

EPA’s and IEPA’s remedial action 

objectives for the Site are to: Prevent 

exposure to contaminated groundwater; 

prevent or minimize further migration 

of the contaminated groundwater 

plumes located at and downgradient of 

the Beloit Corp. manufacturing building; 

and to remediate the contaminated 

groundwater to the more stringent of 

either the MCLs or applicable State of 

Illinois Groundwater Quality Standards 

(35 IAC Part 620), including 35 IAC Part 

620.410 Class I Groundwater Quality 

Standards for Class I Potable Resource 

Groundwater, or 35 IAC Part 620.450 

Alterative Groundwater Quality 

Standards. 

The only remedial alternative EPA 

and IEPA considered for the Former 

Beloit Corp. Research Center Property 

was institutional controls (ICs). EPA and 

IEPA did not evaluate an active 

groundwater remedy for the Former 

Beloit Corp. Research Center Property 

because the RI determined that the 

groundwater in this area of the Site was 

not contaminated. 

EPA and IEPA issued a Record of 

Decision (ROD) for the Site in 2004. The 

ROD selected a cleanup remedy for the 

Site which included: Continued 

operation and monitoring of the 

groundwater pump and treat ISCA 

system located on the Former Beloit 

Corp. Manufacturing Property; VOC 

source area treatment on the Former 

Beloit Corp. Manufacturing Property by 

in-situ chemical oxidation; monitored 

natural attenuation to address the offproperty and off-Site groundwater 

contamination; and ICs. 

The only remedy component 

applicable to the Former Beloit Corp. 

Research Center Property in the ROD is 

the ICs. The ICs would be in the form 

of a restrictive covenant and would 

prohibit the use of shallow groundwater 

on the Beloit Corp. property (i.e., the 

Former Beloit Corp. Manufacturing 

Property and the Former Beloit Corp. 

Research Center Property) for potable 

purposes until the drinking water 

standards in the groundwater are 

attained. The ROD specifies that the 

current facilities at the Beloit Corp. 

property use groundwater from a lower 

groundwater aquifer that is not affected 

by the VOC contamination, and that this 

deeper groundwater can continue to be 

used. 

IEPA conducted additional 

investigations in the former 

manufacturing plant source area of the 

Site in 2006 for the remedial design. 

IEPA’s investigations indicated that the 

source area of the groundwater 

contamination is larger than previously 

indicated (but not on the Former Beloit 

Corp. Research Center Property), and 

that the aquifer material is not 

conducive to in-situ chemical treatment. 

EPA and IEPA issued an Explanation 

of Significant Differences (ESD) in 2007 

modifying the Site remedy. The ESD 

changed the treatment component of the 

remedy from in-situ chemical oxidation 

to installing one or more additional 

extraction wells south and southeast of 

the Erection Bay on the Former Beloit 

Corp. Manufacturing Property. The new 

extraction wells would capture 

additional groundwater contamination. 

The groundwater from the additional 

wells would be conveyed to the existing 

ISCA air-stripper for treatment and 

discharged to the Rock River under the 

NPDES permit. The ESD also included 

pneumatic fracturing at the additional 

extraction well locations to loosen up 

the soil to increase the effectiveness of 

the new wells. 

The ESD did not alter the conclusion 

that the southern area of the Erection 

Bay in the manufacturing plant area of 

the Former Beloit Corp. Manufacturing 

Property is the primary source of the 

groundwater contamination at the Site. 

The ESD did not change the IC 

component for the Former Beloit Corp. 

Research Center Property or require any 

additional remedial action for the 

Former Beloit Corp. Research Center 

Property. 

The ROD as modified by the ESD, 

requires: (1) The continued operation of 

the existing groundwater pump and 

treat ISCA system at the source area on 

the Former Beloit Corp. Manufacturing 

Property (not on the Former Beloit Corp. 

Research Center Property); (2) installing 

additional extraction wells in the source 

area on the Former Beloit Corp. 

Manufacturing Property (not on the 

Former Beloit Corp. Research Center 

Property); (3) groundwater monitoring; 

(4) operating and maintaining (O&M) 

the ISCA pump and treat system on the 

Former Beloit Manufacturing Property 

(not on the Former Beloit Corp. 

Research Center Property), and (5) 

implementing ICs to prohibit the 

withdrawal of the shallow groundwater 

for potable use. 

Response Actions 

IEPA completed the remedial action 

to expand and increase the effectiveness 

of the 1996 groundwater pump and treat 

system on the Former Beloit 

Manufacturing Property in 2008. IEPA 

expanded the groundwater pump and 

treat building to accommodate the 

increase in the volume of extracted 

groundwater, installed three new 

groundwater extraction wells, and shut 

down one extraction well (EW01) to 

adjust the zone of groundwater 

extraction to better target the source 

area. 

IEPA conducted pneumatic fracturing 

at the three additional extraction well 

locations to increase the volume of 

water pumped out by the extraction 

wells in the source area. IEPA 

connected the new extraction wells to 

the groundwater treatment system and 

tested the system to ensure it was 

properly operating. EPA documented 

the completion of the remedial action 

construction activities in a September 

29, 2008 PCOR (Docket Document ID 

EPA–HQ–SFUND–1990–0011–0260). 

Cleanup Levels 

The cleanup levels for the 

groundwater contaminants at the Beloit 

Corp. Site are federal MCLs and/or 

Illinois Class I standards, whichever are 

more stringent. The RI determined that 

the groundwater below the Former 

Beloit Corp. Research Center Property is 

upgradient of, and is not affected, by the 

groundwater contamination at the Site, 

and that the groundwater below the 

Research Center Property already meets 

the cleanup levels for the Site. 

IEPA conducted an updated hydraulic 

capture zone analysis of the expanded 

groundwater extraction system in 2013. 

The updated capture zone analysis 

further confirms that the VOCcontaminated groundwater originating 

from the former Erection Bay source 

area is being captured and treated by the 

expanded ISCA pump and treat system, 

and is not affecting the Former Beloit 

Corp. Research Center Property. The 

results of the capture zone analysis are 

provided in the Task 1 Follow-Up 

Activities to the Five-Year Review 

Report, June 2014 (Docket Document ID 

EPA–HQ–SFUND–1990–0011–0269). 

Annual VOC sampling of a deep, 

water supply well located on the Former 

Beloit Corp. Research Center Property 

(well WW441K) also confirms that the 

groundwater in the lower aquifer below 

the Former Beloit Corp. Research Center 

Property has not been affected by Site 

contamination. Well WW441K is 

located in the lower aquifer, which is 

separated from the upper aquifer by 

approximately 40 feet of silty clay. The 

well is screened from 175 to 185 ft-bgs 

and from 225 to 235 ft-bgs, and is 

approximately 100 feet deeper than the 

deepest contamination detected at the 

Site. 

Well WW441K is used to supply 

water for employee toilets and sink 

uses, and for limited cleaning purposes. 

The Illinois Department of Public 

Health requires the well to be sampled 

annually for VOCs and for other 

contaminants as scheduled (Water 


sradovich on DSK3GMQ082PROD with RULES
Federal Register / Vol. 83, No. 136 / Monday, July 16, 2018 / Rules and Regulations 32803 

System ID IL3121418). The VOC 

analytical results for 2012 through 2017 

for WW441K show no detected VOCs. 

The 2013 analyses of pesticides, 

herbicides, semi-volatile organic 

compounds and metals show no 

detectable organics and metals 

concentrations below drinking water 

standards in the water. 

A second, deeper water supply well is 

located on the Former Beloit Corp. 

Research Center Property (WW441L). 

Well WW441L is an open borehole well 

from 330 ft-bgs to 554 ft-bgs and is 

maintained as a backup well for fire 

protection. Based on other Site 

information and data, well WW441L is 

also not expected to be impacted by 

Site-related contamination. Additional 

information about wells WW441K and 

WW441L is provided in the Technical 

Memorandum: Paperchine Investment 

Group LLC Water Supply Wells at Beloit 

Corp. NPL Site, June 2017, Docket 

Document ID EPA–HQ–SFUND–1990– 

0011–0284. 

Operation and Maintenance (O&M) 

The only O&M required for the 

Former Beloit Corp. Research Center 

Property is to maintain and monitor 

upgradient groundwater monitoring 

wells on the property as needed, and to 

maintain, monitor and enforce the RODrequired IC. 

PPC filed a Uniform Environmental 

Covenant, pursuant to the Illinois 

Uniform Environmental Covenants Act 

[UECA, 765 Illinois Compiled Statutes 

(ILCS) 122] on the Former Beloit Corp. 

Research Center Property, PIN 03–12– 

452–003, with the Winnebago County 

Recorder’s Office on February 7, 2013, 

Instrument 20131006292. A copy of the 

recorded Environmental Covenant (EC) 

is in Docket Document ID EPA–HQ– 

SFUND–1990–0011–0276 in the Docket. 

PPC’s EC: (1) Restricts or limits the 

use of the land to industrial land use; (2) 

prohibits the construction of new or 

non-existing wells or consumptive use 

of the groundwater underlying the 

property; (3) prohibits any activity that 

may interfere with or would affect the 

integrity or the configuration of the RA 

at the Site, or the operation and 

maintenance of any RA component; and 

(4) grants authorized representatives of 

IEPA and EPA the right to enter and 

have continued access to the Site at 

reasonable times to perform the RA. The 

covenant ‘‘runs with the land’’ and 

remains in effect until the contaminated 

groundwater at the Site is restored to the 

more stringent of either the federal 

MCLs or State of Illinois Class I 

groundwater standards for all 

contaminants of concern. Similar ICs 

will be placed on the Former Beloit 

Corp. Manufacturing Property. IEPA is 

also in the process of establishing a 

Groundwater Management Zone to 

prevent the use of contaminated 

groundwater in other Site areas beyond 

the former Beloit Corp. property. 

Other O&M at the Site includes 

IEPA’s operation of the groundwater 

treatment system on the Former Beloit 

Corp. Manufacturing Property and semiannual groundwater monitoring at 21 

groundwater monitoring locations. Eight 

of the groundwater monitoring locations 

have nested wells screened at different 

elevations within the aquifer to monitor 

the groundwater at different depths. 

IEPA’s groundwater monitoring 

indicates that the contaminant plume 

has stabilized and that the contaminated 

groundwater is not moving off-Site. 

IEPA samples nearby residential wells 

every two years to ensure that the 

groundwater containment system 

continues to be protective. The 

concentrations of contaminants in 

private residential wells have been 

below MCLs since 2001. 

Five-Year Review 

EPA and IEPA conducted the first 

statutory five-year review (FYR) at the 

Beloit Corp. Site under Section 121(c) of 

CERCLA on September 27, 2013. A FYR 

evaluates whether the remedial action at 

a site remains protective of human 

health and the environment at sites 

where contaminants remain on-site at 

levels that do not allow for unlimited 

use and unrestricted exposure. 

The FYR Report determined that a 

protectiveness determination could not 

be made at the Site without further 

information to assess the potential for 

vapor intrusion into nearby residences 

and commercial properties, and updated 

groundwater modeling. The issues and 

recommendations in the FYR Report did 

not apply to the Former Beloit Corp. 

Research Center Property, which is 

upgradient from the source area of the 

groundwater contamination at the Site 

and is not subject to vapor intrusion 

concerns. 

IEPA conducted a vapor intrusion 

assessment and updated the Site 

groundwater model to address the 

issues in the FYR Report. The vapor 

intrusion assessment determined that 

the Site does not pose a risk to Site 

workers or nearby residents through the 

vapor intrusion pathway. The updated 

Site groundwater model capture zone 

analysis demonstrates that the 

groundwater contamination in the 

Former Beloit Corp. Manufacturing 

Property source area of the Site is being 

captured and treated by the expanded 

groundwater pump and treat system 

required by the 2007 ESD. 

EPA issued a FYR Addendum 

documenting that the Site is currently 

protective of human health and the 

environment on January 25, 2018. The 

FYR Addendum also determined that in 

order for the Site to be protective over 

the long-term an EC must be 

implemented on the Former Beloit Corp. 

Manufacturing Property, a GMZ must be 

implemented in Site areas beyond the 

Former Beloit Corp. property, and an 

institutional controls action plan and 

long-term stewardship plan for 

monitoring and maintaining ICs need to 

be implemented. The next FYR is 

scheduled to be completed by 

September 27, 2018. 

Community Involvement 

EPA and IEPA satisfied public 

participation activities for the Site 

required in CERCLA Section 113(k), 42 

U.S.C. 9613(k), and CERCLA Section 

117, 42 U.S.C. 9617. IEPA has actively 

engaged the Rockton community about 

the Beloit Corp. Superfund Site since 

the 1980s. IEPA held public meetings 

and availability sessions about the Site 

throughout the RI/FS at the Talcott Free 

Library and the Hononegah High 

School. These forums allowed citizens, 

local officials and the media to learn 

about the Site, ask questions and 

express their concerns directly to IEPA 

community involvement and technical 

staff. IEPA announced all meetings and 

availability sessions to the public in 

local newspaper advertisements and 

IEPA fact sheets prior to the meetings. 

IEPA developed and distributed four 

fact sheets about the Site throughout the 

RI/FS. The fact sheets provided 

information about the residential well 

sampling, the environmental 

investigations, Site updates, public 

meeting announcements, the proposed 

plan, new documents and reports added 

to the information repository, the start 

and completion of cleanup actions, 

schedule delays and the establishment 

of the Administrative Record. 

IEPA published three weekly notices 

about its proposed cleanup plan for the 

Site in the Rockton Herald in 2004 prior 

to issuing the ROD. The notices 

included information about the 30-day 

public comment period and the public 

meeting. IEPA mailed a proposed plan 

fact sheet summarizing the proposed 

cleanup plan and the other cleanup 

alternatives that were considered, to 

citizens, the media, and local officials 

prior to selecting a final cleanup plan in 

the 2004 ROD. The fact sheet also 

announced and included information 

about the public comment period and 

the public meeting. IEPA extended the 

public comment period for the proposed 

plan period by 30 days in response to 


sradovich on DSK3GMQ082PROD with RULES
32804 Federal Register / Vol. 83, No. 136 / Monday, July 16, 2018 / Rules and Regulations 

a citizen request. IEPA responded to 26 

questions and comments about the Site 

and the proposed cleanup plan in a 

responsiveness summary that is 

attached to the ROD. 

IEPA published a notice announcing 

the 2013 FYR and inviting the public to 

comment and express their concerns 

about the Site at the start of the FYR. 

IEPA published these notices in the 

Rockton Herald and the Rockford 

Register Star. 

EPA published notices announcing 

this proposed Direct Final Partial 

Deletion in the Rockton Herald and the 

Rockford Register Star prior to 

publishing this deletion in the Federal 

Register. Documents in the deletion 

docket which EPA relied on to support 

this partial deletion of the Site from the 

NPL are available to the public in the 

information repositories and at http://

www.regulations.gov. 

Determination That the Criteria for 

Deletion Have Been Met 

The Former Beloit Corp. Research 

Center Property portion of the Beloit 

Corp. Site, PIN 03–12–452–003, meets 

all of the site deletion requirements 

specified in Office of Solid Waste and 

Emergency Response (OSWER) 

Directive 9320.22, Close-Out Procedures 

for National Priorities List Sites. All 

cleanup actions for this property 

required by the 2004 ROD and 2007 ESD 

(i.e., the IC) have been implemented. 

The RI determined that the groundwater 

below the Former Beloit Corp. Research 

Center Property is upgradient of, and is 

not affected, by the groundwater 

contamination at the Site, and that the 

groundwater below the Former Beloit 

Corp. Research Center Property already 

meets cleanup levels. IEPA’s updated 

capture zone analysis in 2013, and 

sampling at the deep, water supply well 

in the lower aquifer on the property 

required by the Illinois Department of 

Public Health, provide additional 

confirmation that the groundwater 

below the Former Beloit Corp. Research 

Center Property is not contaminated and 

that this portion of the Site does not 

pose a threat to human health or the 

environment. Therefore, EPA has 

determined that no further Superfund 

response is necessary to protect human 

health or the environment at the Former 

Beloit Corp. Research Center Property. 

The NCP (40 CFR 300.425(e)) states 

that a Superfund site or a portion of a 

site may be deleted from the NPL when 

no further response action is 

appropriate. EPA, in consultation with 

the State of Illinois, has determined that 

all required response actions have been 

implemented at the Former Beloit Corp. 

Research Center Property portion of the 

Beloit Corp. Site, PIN 03–12–452–003, 

and that no further response action by 

the responsible parties is appropriate on 

this property. 

V. Partial Deletion Action 

EPA, with concurrence of the State of 

Illinois through the IEPA, has 

determined that all appropriate 

response actions under CERCLA at the 

Former Beloit Corp. Research Center 

Property, PIN 03–12–452–003, other 

than maintenance and monitoring of 

groundwater monitoring wells and ICs, 

and five-year reviews, have been 

completed. Therefore, EPA is deleting 

the Former Beloit Corp. Research Center 

Property, PIN 03–12–452–003, of the 

Beloit Corp. Site from the NPL. 

Because EPA considers this action to 

be noncontroversial and routine, EPA is 

taking it without prior publication. This 

action will be effective September 14, 

2018 unless EPA receives adverse 

comments by August 15, 2018. If 

adverse comments are received within 

the 30-day public comment period, EPA 

will publish a timely withdrawal of this 

direct final Notice of Partial Deletion 

before the effective date of the partial 

deletion and it will not take effect. EPA 

will prepare a response to comments 

and continue with the deletion process 

on the basis of the Notice of Intent to 

Partially Delete and the comments 

already received. There will be no 

additional opportunity to comment.
