and Oil-fired Electric Utility Steam 

Generating Units and Standards of 

Performance for Fossil-Fuel-Fired 

Electric Utility, Industrial-CommercialInstitutional, and Small IndustrialCommercial-Institutional Steam 

Generating Units, generally referred to 

as the mercury and air toxics standards 

(MATS Rule), which established 

emissions standards for new and 

existing coal- and oil-fired electric 

utility steam generating units. The EPA 

received petitions, pursuant to section 

307(d)(7)(B) of the Clean Air Act, from 

a number of interested parties 

requesting reconsideration of certain 

issues in the rule. On July 20, 2012, the 

EPA issued a letter, stating its intent to 

grant the petitions for reconsideration 

on certain new source issues related to 

the emission standards issued under 

Clean Air Act section 112, including 

measurement issues related to mercury 

and the data set to which the variability 

calculation was applied when 

establishing the new source standards 

for particulate matter and hydrochloric 

acid. 

The Clean Air Act authorizes the EPA 

to stay the effectiveness of a rule if the 

Administrator has convened a 

proceeding to reconsider the rule. Under 

section 307(d)(7)(B) of the Act, ‘‘The 

effectiveness of the rule may be stayed 

during * * * reconsideration * * * by 

the Administrator or the court for a 

period not to exceed three months.’’ 42 

U.S.C.7607(d)(7)(B). In its letter granting 

the petitions for reconsideration on 

certain issues relating to the Clean Air 

Act section 112 new source standards, 

the EPA stated that it intended to 

exercise its authority under section 

307(d) to stay the effectiveness of those 

new source standards for 3 months. 

II. Issuance of a Partial Stay Relating to 

Clean Air Act Section 112(d) New 

Source Standards 

Pursuant to section 307(d)(7)(B) of the 

Clean Air Act, the EPA hereby stays the 

effectiveness of 40 CFR 63.9984(a), 

63.10005(g), 63.10030(c), Table 1 in 

subpart UUUUU of 40 CFR part 63, and 

row 2 of Table 3 in subpart UUUUU of 

40 CFR part 63 for 3 months. Thus, by 

this action, we are staying the 

effectiveness of these provisions of the 

rule, published in the Federal Register 

on February 16, 2012 (77 FR 9304). 

Accordingly, this action also stays the 

effectiveness of any monitoring, 

recordkeeping, and reporting 

requirements related to the section 

112(d) new source standards. This stay 

does not apply to any other provisions 

of the rule. 

This stay of effectiveness will remain 

in place until November 2, 2012.

National Oil and Hazardous 

Substances Pollution Contingency 

Plan; National Priorities List: Partial 

Deletion of the Eastland Woolen Mill 

Superfund Site 

AGENCY: Environmental Protection 

Agency. 

ACTION: Direct final rule. 

SUMMARY: The Environmental Protection 

Agency (EPA) Region 1 is publishing a 

direct final Notice of Partial Deletion for 

portions of the Eastland Woolen Mill 

Superfund Site (Site), located in 

Corinna, Maine, from the National 

Priorities List (NPL). 

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 (NCP). This direct 

final partial deletion is being published 

by EPA with the concurrence of the 

State of Maine, through the Maine 

Department of Environmental 

Protection, because EPA has determined 

that all appropriate response actions at 

these identified parcels under CERCLA, 

other than five-year reviews, have been 

completed. However, this partial 

deletion does not preclude future 

actions under Superfund. 

This partial deletion pertains to all 

Site media (soil and groundwater) of the 

properties proposed for deletion. 

DATES: This direct final partial deletion 

is effective October 1, 2012 unless EPA 

receives adverse comments by 

September 4, 2012. If adverse comments 

are received, EPA 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.

I. Introduction 

EPA Region 1 is publishing this direct 

final Notice of Partial Deletion for the 

Eastland Woolen Mill (Site), from the 

National Priorities List (NPL). This 

partial deletion pertains to all site 

media, including soil and groundwater 

for the following properties: 

Properties owned by the Town of Corinna 

that include properties described in 

Quitclaim Deed dated August 18, 1997 and 

recorded in Book 6471, Page 278, also 

identified as Lot 118 in Tax Map 18 dated 

2004 and several additional properties that 

were part of the former Eastland Woolen Mill 

complex that were acquired due to a tax 

foreclosure. The tax foreclosure properties 

are described in the Penobscot County 

Registry of Deeds in Condemnation Order 

dated December 8, 1999 and recorded in 

Book 7251, Page 47 and a portion of the 

property has been subdivided in accordance 

with a plan dated October 19, 2004 entitled, 

‘‘Subdivision Plan for the Town of Corinna 

of Main Street Subdivision on Main Street, 

Hill Street & St. Albans Road in Corinna, 

County of Penobscot, Maine,’’ recorded in 

said Registry in Plan File 2004, No. 167 (the 

‘‘Subdivision Plan’’). Specifically subdivision 

Lots 2, 3, 4, 5, 6, 8, 9, 10, the portion of 

Subdivision Lot 1 north of the Central Maine 

Power property and a portion of Lot 54 on 

Tax Map 18 along with Lot 53 on Tax Map 

18, are proposed for deletion. The portions of 

Main Street and Hill Street within the 

subdivision are also proposed for deletion. 

Lot 53 on Tax Map 18 is also recorded in 

Book 853, Page 391 as a warranty deed dated 

September 26, 1913 and is known as 

‘‘Winchester Park’’. 

Property owned by the State of Maine 

Department of Conservation identified in 

Release Deed dated December 5, 2003 Book 

9114, Page 194, also identified in Tax Map 

18 as Map 15 Lot 10 (which a portion of the 

State of Maine Department of Conservation 

recreational trail that runs through the Town 

of Corinna). 

Property owned by the State of Maine 

Department of Transportation described in a 

Notice of Layout and Taking dated May 3, 

2000 and recorded in the Penobscot County 

Registry of Deeds in Book 7357, Page 29, and 

being generally depicted on the Survey Plan 

Showing Property Subject to Proposed 

Environmental Covenants for Maine 

Department of Environmental Protection, 

Corinna, Penobscot County, Maine, which is 

recorded in the Penobscot County Registry of 

Deeds as Plan File 2012 No. 20, dated March 

29, 2012, but excluding the portion of the 

Maine Department of Transportation 

property bounded by Town of Corinna 

Subdivision Lot 1, the East Branch of the 

Sebasticook River, Route 7, and Nokomis 

Road. 

Property owned by Central Maine Power 

identified in indenture dated May 2, 1956 

and recorded in the Penobscot County 

Registry of Deeds in Book 1532, Page 228, 

and generally depicted as Central Maine 

Power Company land in the Town of Corinna 

tax records as Lot 4 on Tax Map 20. 

The properties proposed for deletion 

are shown in Figure 11 of Partial 

Deletion Technical Memorandum dated 

June 2012 and will be referred to 

hereafter as ‘‘the properties proposed for 

deletion’’. All Tax Map references are 

based on the Town of Corinna 2004 Tax 

Maps and the ‘‘Survey Plan Showing 

Property Subject to Proposed 

Environmental Covenants for Maine 

Department of Environmental 

Protection, Corinna, Penobscot County, 

Maine’’ which is recorded in the 

Penobscot County Registry of Deeds as 

Plan File 2012 No. 20, dated March 29, 

2012. 

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 

Eastland Woolen Mill Superfund 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 Fundfinanced remedial action if future 

conditions warrant such actions. 

Because EPA considers this action to 

be noncontroversial and routine, this 

action will be effective October 1, 2012 

unless EPA receives adverse comments 

by September 4, 2012. Along with this 

direct final Notice of Partial Deletion, 

EPA is co-publishing a Notice of Intent 

for Partial Deletion in the ‘‘Proposed 

Rules’’ section of the Federal Register. 

If adverse comments are received within 

the 30-day public comment period on 

this partial deletion action, EPA will 

publish a timely withdrawal of this 

direct final Notice of Partial Deletion 

before the effective date of the partial 

deletion and the partial deletion will 

not take effect. EPA will, as appropriate, 

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. There will be no 

additional opportunity to comment. 

Section II of this document explains 

the criteria for deleting sites from the 

NPL. Section III discusses procedures 

that EPA is using for this action. Section 

IV discusses the properties proposed for 

deletion and demonstrates how it meets 

the deletion criteria. Section V discusses 

EPA’s action to delete these Site parcels 

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, 


sroberts on DSK5SPTVN1PROD with RULES
45970 Federal Register / Vol. 77, No. 149 / Thursday, August 2, 2012 / Rules and Regulations 

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 

properties proposed for deletion: 

(1) EPA has consulted with the State 

of Maine prior to developing this direct 

final Notice of Partial Deletion and the 

Notice of Intent for Partial Deletion copublished in the ‘‘Proposed Rules’’ 

section of the Federal Register. 

(2) EPA has provided the State 30 

working days for review of this notice 

and the parallel Notice of Intent for 

Partial Deletion prior to their 

publication today, and the State, 

through the Maine Department of 

Environmental Protection, has 

concurred on the partial deletion of the 

Site from the NPL. 

(3) Concurrently 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 a major 

local newspaper, Bangor Daily News. 

The newspaper notice announces the 

30-day public comment period 

concerning the Notice of Intent for 

Partial Deletion of the Site from the 

NPL. 

(4) The 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 

above. 

(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 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 

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 Site Partial Deletion 

The following information provides 

EPA’s rationale for deleting the 

properties proposed for deletion: 

Site Location 

The Eastland Woolen Mill Superfund 

Site (MED980915474) (Site) is located in 

the center of the Town of Corinna, 

Penobscot County, Maine, 

approximately 6 miles north of Newport 

and 25 miles northwest of Bangor, 

Maine. Approximately 800 people live 

within one mile of the Site, and 2,500 

people live within four miles. 

The Town of Corinna is located 

within the East Branch of the 

Sebasticook River (EBSR) watershed, 

which drains to Sebasticook Lake 

approximately three miles south of the 

Town. Topography within the 

watershed is typified by gently rolling 

hills to steeply sloping ridges, varying 

from narrow valleys to fairly expansive 

low-lying floodplains. Elevations within 

the immediate vicinity of Corinna range 

from 200 to 320 feet above mean sea 

level (msl). The former Eastland Woolen 

Mill straddled the EBSR and the 

southern portion of the former Mill 

Pond. 

Site Description 

At the time of the placement of the 

Eastland Woolen Mill on the EPA NPL, 

the Site included the former Eastland 

Woolen Mill property and areas where 

contamination has migrated or 

otherwise come to be located due to mill 

operations. The Eastland Woolen Mill 

property was a 21-acre parcel located on 

the north side of Main Street, Corinna, 

in central Maine. There was a 250,000 

square foot Mill building, two dams, 

and several out buildings on site. The 

mill building straddled the East Branch 

of the Sebasticook River with one dam 

located under the building near Main 

Street; the other dam is located 

approximately 500 feet north of the mill 

and maintains the water level of 

Corrundel Lake, a portion of the EBSR. 

The two dams also created an on-site 

mill pond. The Site is bordered to the 

north by Corundel Lake and residential 

property, to the south by Main Street, to 

the east by the Dexter Road and the 

Methodist Church, and on the west by 

Route 43 and several residential 

properties. As a result of the data 

collected to support the Engineering 

Evaluation and Cost Analysis (EE/CA) 

for a non-time-critical removal action 

(NTCRA) and the remedial investigation 

(RI) program, the footprint of the Site 

was better defined to extend south 

across Main Street and downstream in 

the EBSR. 

Operational History 

The Site was formerly dominated by 

the Eastland Woolen Mill building 

complex which, before its demolition in 

2000, was comprised of a large 

manufacturing building and several 

ancillary structures, with a total area of 

250,000 square feet. The buildings stood 

on both sides of and over the EBSR, a 

State-designated Class C water, which 

flows north to south through the center 

of Corinna. The original woolen-mill 

structure was built in the late 1800s or 

early 1900s. The property was a woolen 

mill as far back as 1912. Eastland 

Woolen Mill owned and operated the 

mill from 1936 to October 1996, when 

they closed the mill. Prior to closing in 

1996, Eastland Woolen Mill was a 

manufacturer and finisher of wool and 

blended woven fabric. Fabric finishing 

included of the fabric to meet product 

or customer requirements. This dyeing 

operation took place in dye kettles and 

utilized various chemicals, including 

dyes and dye-aids that reportedly 

contained biphenyl and chlorinated 

benzene compounds, including 1,2- 

dichlorobenzene, 1,3-dichlorobenzene, 

1,4-dichlorobenzene, and 1,2,4- 

trichlorobenzene. 

Conditions That Led to Placement on 

National Priorities List (NPL) 

Until construction of the Town of 

Corinna Wastewater Treatment Plant 

(WWTP) in 1969, liquid wastes from the 

mill were discharged to the ground 

surface beneath mill buildings, to Mill 

Pond Dam tailrace, and ultimately the 

EBSR. It was not until 1977 that all 

liquid waste streams were finally 

directed to the WWTP. As a result of 

these discharges, overburden soil and 

bedrock underlying mill buildings and 

river sediment and underlying soil 

extending several hundred feet 

downgradient were contaminated with 

chlorinated benzene compounds. 

Groundwater was contaminated at 

concentrations well above federal 

drinking water Maximum Contaminant 

Levels (MCLs) and State of Maine 

drinking water Maximum Exposure 

Guidelines (MEGs). Routine pumping of 

nearby residential bedrock wells spread 

the contamination laterally along 

bedrock bedding-plane fractures. 

Groundwater contamination was first 

documented in Corinna in 1983, when 


sroberts on DSK5SPTVN1PROD with RULES
Federal Register / Vol. 77, No. 149 / Thursday, August 2, 2012 / Rules and Regulations 45971 

a MEDEP employee noticed a strange 

odor and taste in drinking water at the 

Gallison Restaurant located across the 

street from the Mill. Several water 

samples collected from the restaurant 

showed the presence of 

monochlorobenzene, dichlorobenzenes 

and trichlorobenzenes. Later in 1983, 

granular activated carbon (GAC) filters 

were installed on five water supply 

wells (residential and business) near the 

Mill to mitigate exposures to 

chlorinated benzene compounds. 

Eastland Woolen Mill initiated formal 

environmental investigations in 1984 by 

performing a preliminary hydrogeologic 

investigation of the downtown area. The 

work included the completion of soil 

borings, installation of monitoring wells 

and piezometers, sampling and analysis 

of soil and groundwater, and a 

preliminary fracture-trace analysis. The 

investigation concluded that additional 

work was needed to identify a 

contaminant source area. By 1988, 

Eastland Woolen Mill had completed a 

study of residences and businesses at 

risk from the groundwater 

contamination and had investigated 

potential locations for installation of a 

public water supply system. It was 

concluded that contamination had 

likely spread via bedrock fractures and 

faults. Five additional private water 

supply wells were fitted with granular 

activated carbon filters based on results 

of water supply well sampling 

performed between 1983 and 1988. 

In 1993, Eastland Woolen Mill 

completed Phase I of a chlorinated 

benzene contamination investigation in 

the downtown area. The report 

identified the tailrace beneath the 

Eastland Woolen Mill and the UST area 

where dye-aid had been stored as 

possible source locations. 

Eastland Woolen Mill removed three 

underground storage tanks (USTs) from 

the UST Area in 1994. Chlorinated 

benzene compounds were detected in 

soil samples collected from the bottom 

of the excavation. Because free product 

was reported in the excavation and soil 

staining was observed, an overburden 

groundwater recovery well (R–1), 

consisting of a 30-inch-diameter 

corrugated metal pipe with slits in the 

bottom five feet and surrounded by 

crushed stone, was installed at the Site 

after removal of the USTs. In addition, 

a drum containing a dark oil-like 

substance was unearthed in the UST 

excavation. Recovery Well R–1 was 

pumped to collect chlorinated benzenecontaminated groundwater and flush 

contaminants from the ‘‘smear’’ zone 

between August 1994 and sometime in 

1995. In conjunction with the pumping 

of groundwater from Well R–1, Eastland 

Woolen Mill instituted pumping of 

groundwater from the bedrock well on 

Lot 122, south of Main Street, now 

referenced as Recovery Well R–2. 

In the fall of 1995, during the 

installation of water supply lines to 

serve residences affected by 

contamination, a dense non-aqueousphase liquid (DNAPL) was reportedly 

observed within the till material 

beneath the gravel riverbed just 

downstream of the Main Street bridge. 

A consultant for Eastland Woolen Mill, 

Acheron, Inc., performed additional 

sampling of the sediments in the 

riverbed downstream of the Eastland 

Woolen Mill and found chlorinated 

benzene compounds and petroleum 

hydrocarbons both within the silty till 

layer beneath the rocky gravel riverbed 

and in a floodplain on the west side of 

the river. 

After closure of the Eastland Woolen 

Mill in 1996, MEDEP sampled soils 

around the former USTs to evaluate 

whether residual soil contamination 

was present and acting as a source of 

groundwater contamination. This effort 

was supplemented in 1998 with 

additional analytical parameters and 

sampling of a background location. In 

1997, MEDEP performed sediment 

sampling with field chemical screening 

to gain information on the magnitude of 

river bottom contamination documented 

by Acheron, Inc. in 1995. Additional 

sediment and surface water samples 

were collected from the river in 1998 for 

analysis. These investigations confirmed 

that high concentrations of chlorinated 

benzenes were present in the riverbed 

downstream of the Eastland Woolen 

Mill complex. This data was used to 

prepare the Hazard Ranking System 

scoring package that was submitted to 

EPA for placement of the Site on the 

National Priorities List (NPL). 

National Priorities List Designation 

The Site was proposed for inclusion 

on the NPL on April 23, 1999 (64 FR 

19968). It was listed for final inclusion 

on the NPL on July 22, 1999 (64 FR 

39878–39885). 

State Response Action 

In 1997, MEDEP performed an 

emergency response action to remove 

54,673 pounds of various hazardous 

substances from process pipes, 

containers and vessels located within 

the Mill. 

Land Use Assumptions 

Future land use assumptions for the 

Site and surrounding areas (included 

the parcels proposed for deletion) are 

based on the Reuse Plan developed by 

the Town of Corinna. A large portion of 

the Site in the center of town has been 

targeted for a mix of commercial, 

residential and mixed-use development. 

The water supply system was expanded 

by the local water district to support 

future growth. The land use for 

properties proposed for deletion 

include: the Town of Corinna 

subdivision parcels 2, 3, 4, 5, 6, 8, 9, 10, 

a portion of Lot 54 on Tax Map 18, and 

Lot 118 on Tax Map 18, which are part 

of the targeted mix of commercial, 

residential, and mixed use 

development; one property owned by 

the Town of Corinna (Lot 53 on Tax 

Map 18) that will remain a public park 

(Winchester Park); the State of Maine 

Department of Conservation property 

which is a mixed use rail-trail that is 

primarily used for snowmobile travel; 

the Central Maine Power property that 

is expected to remain an electrical substation; and the State of Maine 

Department of Transportation property 

that is essentially right of way property 

related to Route 7. These land 

assumptions are expected to be valid for 

the foreseeable future. 

Remedial Investigation and Feasibility 

Study (RI/FS) 

From 1998 to 2002, USEPA performed 

a Remedial Investigation/Feasibility 

Study (RI/FS) for Operable Unit I (OUI) 

at the Eastland Woolen Mill site. OUI is 

the groundwater operable unit and 

includes overburden and bedrock 

groundwater contamination and also 

includes areas of deep soil 

contamination remaining after the 

NTCRA. All of the properties proposed 

for deletion are within the study area for 

OUI. The details of the OUI RI/FS can 

be found in the Remedial Investigation 

Report, Supplemental Remedial 

Investigation Report, Human Health 

Risk Assessment Report, and Baseline 

Ecological Risk Assessment Report that 

are included in the Administrative 

Record for the OUI Record of Decision 

(ROD). The RI for the OUI Study Area 

identified two areas where site-related 

contaminants exceeded federal and state 

drinking water criteria in overburden 

groundwater. One area is associated 

with the UST Area/Building 14 subarea, and the other is downgradient of 

the former location of Buildings 1, 1A, 

and 3 within the Eastland Woolen Mill 

complex where liquid wastes were 

discharged. The RI also identified an 

area of bedrock groundwater 

contamination associated with the 

release of contamination from Buildings 

1, 1A, and 3 (Area 1). The major 

groundwater contaminants of concern 

(COCs) were determined to be benzene, 

chlorobenzene, 1,2-dichlorobenzene, 

1,3-dichlorobenzene, 1,4- 


sroberts on DSK5SPTVN1PROD with RULES
45972 Federal Register / Vol. 77, No. 149 / Thursday, August 2, 2012 / Rules and Regulations 

dichlorobenzene, and 1,2,4 

trichlorobenzene. The OUI RI and ROD 

also documented that three satellite 

areas of suspected contamination 

(School Street Yard, Moosehead Mill, 

and Bulk Fuels Storage Area) were not 

considered part of the Site based on the 

absence of contamination that would 

represent an unacceptable threat to 

human health or the environment. A 

fourth area, known as Lot 88, was also 

identified as not requiring any further 

action after the NTCRA removed the soil 

contamination from this property. 

In September 2002, EPA created OUII 

to address the sediment and associated 

floodplain areas of the EBSR 

downstream of NTCRA excavation, as 

well as an area of solid and liquid waste 

disposal known as the old dump. 

During 2002 and 2003, EPA performed 

a series of studies to better define the 

potential for ecological impacts in the 

OUII area. Surface water, sediment, 

floodplain soil, and crayfish tissue 

samples were collected, and biological 

assessments of the benthic macroinvertebrate community were 

performed. The information from these 

studies was presented in a 

Supplemental RI Report. The 

information was also combined with the 

initial RI data to prepare a revised 

Baseline Ecological Risk Assessment 

Report that found there was no 

unacceptable risk to ecological receptors 

in the OUII area. Both reports were 

released in 2004 as part of the 

Administrative Record and were 

available for review during the public 

comment period for the OUII Proposed 

Plan. On September 30, 2004, EPA 

signed a ROD selecting No Further 

Action for OUII of the Site. EPA 

activities in the OUII Study Area are 

complete, and no further activities are 

anticipated for the OUII study area. 

Components of RI Relating to Properties 

Proposed for Deletion 

The RI evaluated the properties 

proposed for deletion. The Town of 

Corinna subdivision lots 8, 9, and 10, a 

portion of Lot 54 on Tax Map 18, along 

with Winchester Park were outside the 

footprint of the former Eastland Woolen 

Mill. The electrical sub-station owner by 

Central Maine Power was also outside of 

the footprint of the former Eastland 

Woolen Mill. Background research and 

Site reconnaissance activities as part of 

the RI and NTCRA along with the 

absence of groundwater contamination 

in the area led to the conclusion that 

these properties were not contaminated. 

Subdivision lots 8, 9 and 10 were 

included in the areas that were used for 

soil handling during the NTCRA, and 

cleanup confirmation work was 

performed at the completion of the 

NTCRA. The Town of Corinna 

subdivision lots 2, 3, 4, 5, and 6 are 

located in an area that was occupied by 

the dry processing operations at the 

Eastland Woolen Mill. This area was 

known as the ‘‘Slab Area’’. As part of 

the OUI RI, five confirmation soil 

borings (SB–00–95 through SB–00–99) 

were completed within Slab Area 

(Figure 5–5 of the RI). The soil borings 

were spaced approximately 100 to 120 

feet apart in the Slab Area (Figure 5–3 

of the RI). One additional soil boring, 

(SB–01–106), was installed as part of the 

NTCRA by Weston in 2001. Table 5–3 

of the RI provides a summary of volatile 

organic compounds (VOCs) detected in 

these Slab Area soil borings. Several 

VOCs were detected at concentrations 

that were below levels of concern for 

human contact. A monitoring well pair 

was installed to determine if the 1,1- 

dichloroethene detected in the soil was 

present in groundwater downgradient of 

the Slab area. VOCs were not detected 

in groundwater downgradient of the 

Slab, confirming that this area was not 

a significant source of groundwater 

contamination. The soil treatment 

facility for the NTCRA was located on 

the Slab Area. After the completion of 

the soil treatment, the Slab Area was 

further characterized to document that 

absence of significant contamination. 

The State of Maine Department of 

Transportation, State of Maine 

Department of Conservation, and Town 

of Corinna (Lot 118 Tax Map 18) all 

owned property that included the 

contaminated sections of the EBSR. The 

extent of the contamination in the EBSR 

was documented by the NTCRA and RI 

investigations. In addition, State of 

Maine Department of Conservation also 

owned property within the former 

Eastland Woolen Mill complex near the 

former pump house and the State of 

Maine Department of Transportation 

owned property that was within and 

adjacent to the former Eastland Woolen 

Mill Complex. The RI and NTCRA 

investigation activities documented that 

these areas contained contaminants of 

concern above the Site specific cleanup 

levels. 

Selected Remedy 

There have been three major decision 

documents for the Eastland Woolen 

Mill. The 2004 Record of Decision for 

Operable Unit II clarified that no action 

was necessary for the areas within the 

East Branch of the Sebasticook River 

study area of the Site located south 

(downstream) from the OUI area. The 

2002 Operable Unit I Record of 

Decision, which was amended in 2006, 

and the 1999 Non-Time Critical 

Removal Action Action Memorandum 

are the decision documents relevant to 

the partial delisting. 

Non-Time-Critical Removal Action 

In January 1999, following the 

evaluation of data collected during an 

expanded site inspection, EPA signed 

an Approval Memorandum authorizing 

the preparation of an Engineering 

Evaluation and Cost Analysis (EE/CA) to 

evaluate potential response alternatives 

for a NTCRA at the Site. The EE/CA 

recommended demolishing the mill 

complex buildings to allow for the 

excavation and treatment of the 

contaminated soils on the Site. After 

completion of a public comment period 

and consideration of the comments, 

EPA signed an Action Memorandum in 

July 1999 to authorize a NTCRA for the 

Eastland Woolen Mill Superfund Site. 

The Action Memorandum was amended 

in June 2000, September 2000, May 

2001, and June 2004. 

The NTCRA included the removal of 

the mill buildings (performed during the 

winter of 1999/2000) and contaminated 

soils from four areas (performed from 

2000–2001). NTCRA work areas 

include: Area 1: Region underlying Mill 

Buildings 1, 1A, and 3 (2001); Area 2: 

River segment down river from the mill 

to the abandoned railroad trestle (2000); 

Area 2a: River segment under the 

abandoned railroad trestle and 

overlapping Area 2 and Area 3 (2000); 

Area 3: River segment for a distance 

several hundred feet beyond the railroad 

trestle (2000); and Area 4: Lot 88, 

Building 9, UST Area, and other 

miscellaneous areas (2000 and 2001). 

During 2000 and 2001, approximately 

75,000 cubic yards (yd3) of chlorinatedbenzene contaminated soils were 

excavated and stockpiled at the Site in 

lined containment structures. In 2001, 

pilot testing of an on-site low 

temperature thermal soil treatment 

system was performed. The results of 

this pilot test indicated that the 

treatment system could meet established 

treatment goals. Full-scale on-site 

treatment of contaminated soil began in 

October 2002 and was completed in 

October 2003. Testing of the soil after 

treatment documented that all of the 

soil that was used for on-site backfill 

contained residual levels of 

contamination below residential 

cleanup standards and met the NTCRA 

groundwater leaching criteria that were 

developed during the NTCRA. To 

support the NTCRA excavation and 

thermal treatment activities, a 

temporary groundwater extraction and 

treatment system (referred to as the 

groundwater management system) was 

constructed to aid in control of 


sroberts on DSK5SPTVN1PROD with RULES
Federal Register / Vol. 77, No. 149 / Thursday, August 2, 2012 / Rules and Regulations 45973 

groundwater infiltration during 

excavation activities. One bedrock well 

and four overburden wells were 

connected to a temporary treatment 

system. The system remained 

operational until November 2004 to 

provide hydraulic control over the 

groundwater plume during the initial 

phase of the NTCRA. A detailed 

summary of the NTCRA source 

removals was presented in the 

November 2006 Final Overall 

Completion Report for the NTCRA. 

Three areas of contaminated soil were 

not accessible to the NTCRA 

excavations. One area was located 

within Area 1 and the other two were 

within the Area 4 UST Area and 

Building 14 Area. These remaining soils 

are located in the saturated zone 

between depths of 6 to 40 ft below 

ground surface (bgs). The final phase of 

the NTCRA targeted the reduction of 

contamination in these source areas 

using in-situ chemical oxidation (ISCO). 

ISCO treatment as part of the NTCRA 

consisted of two full-scale injections of 

iron-catalyzed sodium persulfate (ICP), 

followed by confirmatory soil borings 

and groundwater sampling. These 

injections were performed in July and 

October/November 2005. The NTCRA 

program ended in May 2006 as 

documented by the Final Pollution 

Report (POLREP) for the Eastland 

Woolen Mill NTCRA that was finalized 

in September 2006. 

OUI Record of Decision 

EPA signed a ROD in September 2002 

OUI ROD to address overburden and 

bedrock groundwater and the remaining 

areas of contaminated soil/DNAPL. 

Specifically, the 2002 OUI ROD 

includes the following major 

components: 

• Extraction and treatment of the 

contaminated overburden and bedrock 

groundwater. The extraction system will 

be designed to prevent off-site migration 

of contaminated groundwater, prevent 

contaminated groundwater from having 

an adverse impact on the benthic 

community in the EBSR, and restore the 

aquifer to federal and state MCLs, 

federal non-zero MCLGs and more 

stringent state MEGs. 

• In-situ treatment of the 

contaminated overburden and bedrock 

groundwater and remaining areas of 

contaminated soil and DNAPL. A 

chemical reagent (e.g., Fenton’s Reagent 

or another oxidizing agent) will be 

added to the overburden and bedrock 

aquifer to reduce the mass of 

contaminants in the system. If the mass 

reduction is not sufficient to achieve 

cleanup levels, then enhanced flushing 

(using surfactants/solvents) and 

biological degradation (using biostimulants) will be attempted to further 

reduce the mass of contamination. 

• Connection of certain residences to 

the water supply lines to prevent their 

wells from becoming contaminated, and 

to prevent expansion of the 

contamination in the groundwater. 

• Implementation, monitoring and 

maintenance of institutional controls 

(i.e., deed restrictions) in the form of 

groundwater use restrictions (e.g., 

easements or restrictive covenants) to 

prevent ingestion of groundwater and 

disturbance of the groundwater 

extraction and treatment system. 

• Long-term monitoring of 

groundwater, surface water and 

sediments to evaluate the success of the 

remedial action. 

• Implementation of five-year reviews 

to assess the protectiveness of the 

remedy until cleanup goals have been 

met. 

The 2002 OUI ROD was written prior 

to the completion of the NTCRA that 

commenced in 1999. Therefore, the 

impact of the NTCRA-related excavation 

and treatment of the contaminated 

overburden source areas was uncertain 

at the time of the ROD. Subsequent to 

the signing of the 2002 OUI ROD and 

the completion of the NTCRA 

excavation and treatment program, EPA 

performed assessment monitoring of the 

groundwater. EPA also developed an 

improved conceptual site model 

through additional hydro-geologic 

investigations and groundwater 

modeling. 

Based on the information developed 

after the 2002 OUI ROD, EPA decided 

to amend the 2002 OUI ROD. The 

September 2006 OUI ROD Amendment 

eliminated the groundwater extraction 

and treatment system because the 

contaminant plume was stable and 

groundwater extraction was not 

necessary to contain the plume. The 

OUI ROD Amendment also eliminated 

the enhanced flushing component with 

surfactants or co-solvents because this 

technology was not considered viable 

for the fractured bedrock after further 

evaluation. The OUI ROD Amendment 

retained the emphasis on the in-situ 

chemical oxidation, long-term 

monitoring, and institutional controls. 

Based on the groundwater modeling 

that was performed for the OUI 

Remedial Design, the OUI ROD 

Amendment revised the area where 

institutional controls would be 

necessary and defined three categories 

of properties within the institutional 

control zone. The three property 

categories were identified as IC Zone A 

(ICZ–A), IC Zone B (ICZ–B), and IC 

Zone C (ICZ–C). 

ICZ–A identified those properties that 

will be subject to environmental 

covenants prohibiting use of 

groundwater over the entire property. 

All of the ICZ–A properties had been 

connected to the water line prior to the 

OUI ROD. Within the ICZ–A boundary, 

all existing bedrock and overburden 

water supply wells will be formally 

decommissioned, unless the wells are 

converted to monitoring wells for use in 

the long-term remedial action. ICZ–B 

identified those properties where 

connection to the water line and 

implementation of an environmental 

covenant prohibiting use of 

groundwater over the entire property 

was determined to be necessary as part 

of the OUI ROD and Remedial Design. 

All of these properties were connected 

to the water line as part of the OUI 

Remedial Action, moving these 

properties to ICZ–A; there is therefore 

no longer a functional application for 

ICZ–B. 

ICZ–C identified those properties 

where the current well is not 

contaminated and does not appear to be 

impacting the groundwater 

contamination, however, the 

groundwater modeling suggested that a 

modification to the existing well to 

increase yield, or the installation of a 

new well at locations on the property 

closer to the Site, could have an adverse 

impact on the groundwater 

contamination by inducing migration of 

the groundwater contamination. The 

restrictions on these properties will 

prohibit installation of future 

groundwater wells in locations or at 

depths that differ from existing water 

supply wells located on these 

properties. ICZ–C properties may 

continue to use their private water wells 

within this zone for domestic or other 

uses. There are two properties included 

in ICZ–C. 

OUI ROD and OUI ROD Amendment 

Risk Characterization Summary 

The 2002 OUI ROD included an 

assessment of the potential threats to 

human health in the OUI study area. 

Based on the Human Health Risk 

Assessment prepared as part of the RI 

and the 2002 OUI ROD, the only 

pathways that exceeded EPA’s 

acceptable cancer risk range and/or a 

hazard quotient of concern were 

ingestion of groundwater in the 

overburden and bedrock plumes by a 

future resident. The lifetime cancer risk 

estimate for a combined child and adult 

exposure to the bedrock plume 

groundwater is 6 × 10¥3. Seventy-five 

percent of this risk is due to arsenic, 

with twenty-five percent attributable to 

the 1,4-DCB. EPA’s hazard index of 


sroberts on DSK5SPTVN1PROD with RULES
45974 Federal Register / Vol. 77, No. 149 / Thursday, August 2, 2012 / Rules and Regulations 

concern for non-carcinogenic risk is 

exceeded for children and adults for 

several target organs. The major 

contributors to these exceedances are 

chlorobenzene, 1,2-DCB, 1,3-DCB, 1,4- 

DCB, 1,2,4-TCB and arsenic. These 

COCs also were detected at 

concentrations above federal and state 

maximum contaminant levels (MCLs) 

and any more stringent state maximum 

exposure guidelines (MEGs). The 

lifetime cancer risk estimates for the 

overburden plume groundwater was 2 × 

10¥3. Sixty-seven percent of this risk is 

attributable to 1,4-DCB, with arsenic 

contributing to the remainder of the 

cancer risk. EPA’s hazard index of 

concern for non-carcinogenic risk is 

exceeded for children and adults for 

several target organs. The major 

contributors to these exceedances are 

chlorobenzene, 1,2-DCB, 1,3-DCB, 1,4- 

DCB, 1,2,4-TCB and arsenic. These 

COCs also were detected at 

concentrations above federal and state 

MCLs and any more stringent state 

MEGs. The Baseline Human Health Risk 

Assessment concluded that the 

estimated risk for the soils, surface 

water, or sediments within the OUI area 

do not represent an unacceptable threat 

to human health. Only groundwater 

represents a threat to human health. Soil 

contamination that is causing 

groundwater contamination is also 

relevant to the cleanup action. 

Based on the OUI Baseline Ecological 

Risk Assessment, the OUI ROD 

concluded that contaminant levels in 

surface waters, surface soils and 

sediments within the entire OUI area of 

the EBSR are not sufficiently elevated to 

pose a substantial risk to invertebrates, 

fish or wildlife. Exposure to the 

contaminated water at the groundwater/ 

surface water interface, however, was 

identified as an unacceptable risk to 

those organisms dwelling in this zone. 

Data gathered since the 2002 OUI ROD, 

however, demonstrates that the 

concentration of contaminants in the 

groundwater do not exceed the levels 

that have the potential for an 

unacceptable risk to organisms dwelling 

in the groundwater/surface water 

interface. Therefore, the successful 

implementation of the NTCRA and OUI 

remedy has eliminated this risk. 

Based on the successful removal of 

any soil contamination above the Sitespecific contaminants of concern by the 

NTCRA, the only viable exposure 

pathway for the properties proposed for 

deletion is potential future consumption 

of contaminated groundwater. This 

would only occur upon the expansion of 

the groundwater contaminant plume, 

resulting from a pumping stress from a 

well that is currently outside the area of 

groundwater contamination but within 

the institutional control zone. The OUI 

ROD and OUI ROD Amendment both 

identified the need to maintain the 

water line connections and the 

implementation of institutional controls 

to prevent active water supply wells as 

critical components to protect public 

health. 

OUI ROD and OUI ROD Amendment 

Remedial Action Objectives 

The Remedial Action Objectives in 

the OUI ROD and OUI ROD Amendment 

were identical and are listed below: 

• Prevent the ingestion of 

groundwater containing contaminants 

that exceed federal or state MCLs, 

federal non-zero MCL Goals (MCLGs) 

and more stringent state MEGs, or in 

their absence, an excess cancer risk of 

1 × 10¥6 or a hazard quotient of 1; 

• Prevent, to the extent practicable, 

the off-site migration of groundwater 

containing contaminants at a 

concentration above Site cleanup levels; 

• Prevent, to the extent practicable, 

the discharge of groundwater containing 

contaminants at a concentration above 

levels that could impact ecological 

receptors to the East Branch of the 

Sebasticook River; 

• Restore groundwater to meet federal 

or state MCLs, federal non-zero MCLGs 

or state MEGs (whichever is most 

stringent), or in their absence, an excess 

cancer risk of 1 × 10¥6 or a hazard 

quotient of 1; and 

• Perform long-term monitoring of 

surface water, sediments and 

groundwater to verify that the cleanup 

actions at the Site are protective of 

human health and the environment. 

OUI Remedial Design 

The Remedial Design for the OUI 

Remedial Action was initiated in 2003 

and completed in August 2005. The 

Remedial Design was implemented in 

close coordination with the final phase 

of the NTCRA ISCO program since both 

programs relied on ISCO to reduce the 

mass of contamination in the 

overburden soil and bedrock. As such, 

the NTCRA design support activities 

and the Remedial Design support 

activities are complementary. A series of 

additional studies and investigations 

were performed between 2003 and 2005 

to develop the design for the NTCRA 

ISCO program and the in-situ treatment 

portion of the OUI Remedial Action. 

The additional studies and 

investigations most relevant to the 

properties proposed for deletion were 

(1) The groundwater monitoring to 

update the extent of groundwater 

contamination remaining after the 

NTCRA, (2) the installation of 

additional bedrock monitoring wells to 

refine the aquifer characteristics, and (3) 

groundwater modeling to refine the 

properties that would require land use 

restrictions to prevent consumption of 

contaminated groundwater and 

pumping stresses that could cause the 

expansion of the groundwater plume. 

The Remedial Design refined the 

institutional control zone using 

numerical modeling of bedrock 

groundwater flow and contaminant 

transport to evaluate the potential longterm migration of the bedrock plume 

under both pumping and non-pumping 

scenarios. This modeling, along with the 

groundwater monitoring data, 

documented that the institutional 

control zone will adequately protect 

public health. 

OUI Remedial Action 

The OUI Remedial Action has three 

main components. One is the 

connection of certain residences to the 

water line and the implementation of 

institutional controls to prevent 

exposure to contaminated groundwater 

or pumping stresses that could cause the 

expansion of the groundwater plume. A 

second is the continued treatment of the 

deep contamination soil and 

groundwater to achieve aquifer 

restoration. The third is the long-term 

monitoring, inspections, and five-year 

reviews to assure that the remedial 

action is protective of human health and 

the environment. 

Most of the properties within the 

institutional control zone were 

connected to the local water supply line 

prior to the OUI Remedial Action. Based 

on the results of ongoing bedrock 

groundwater monitoring and numerical 

groundwater modeling performed as 

part of the Remedial Design, it was 

determined that certain residences 

proximal to the Site, including those 

identified on Map 18 as Lots 39, 43, and 

52, were currently impacted by Site 

contaminants or had the potential to be 

impacted in the future. These residences 

were connected to the existing public 

water supply between September and 

December 2005. The land use 

restrictions for the properties proposed 

for deletion were completed in May 

2012 and were recorded in the 

Penobscot Registry of Deeds on June 5, 

2012. The land use restriction, in the 

form of an environmental covenant, will 

prevent current and future use of the 

contaminated groundwater or to prevent 

pumping stresses that could cause the 

groundwater contamination plume to 

migrate. 

The RA also continued the in-situ 

chemical oxidation program initiated by 

the NTCRA. Several additional in-situ 


sroberts on DSK5SPTVN1PROD with RULES
Federal Register / Vol. 77, No. 149 / Thursday, August 2, 2012 / Rules and Regulations 45975 

chemical oxidation injections occurred 

between 2006 and 2008. The Remedial 

Action activities were completed in 

2008, as documented in the OUI Interim 

Remedial Action Report and the 

September 2008 Preliminary Closeout 

Report. The OUI component of the Site 

is now in the long-term response action 

component of the remedial action. The 

ongoing remedial action activities 

include: Completion of the land use 

restrictions; long-term monitoring of 

groundwater and surface water; well 

decommissioning; site demobilization; 

and completion of the in-situ chemical 

oxidation program. A limited soil gas 

program is to be implemented in 2012 

to address soil vapor issues. The 

remedial action will be completed by 

2018 when the State of Maine will take 

over the long term operation, 

maintenance, and monitoring 

requirements. 

Cleanup Goals 

The parcels identified for deletion are 

within the NTCRA and OUI area and, 

therefore, share the same cleanup goals. 

The extent of the groundwater 

contamination above Site-specific 

cleanup goals has been reduced to an 

area that is within the boundaries of the 

Site that will remain after the partial 

deletion. Groundwater monitoring 

performed as part of the long-term 

groundwater monitoring program at the 

Site confirms that the contaminants of 

concern are not at concentrations above 

the Site specific cleanup levels on the 

properties proposed for deletion. 

Groundwater data was collected in 

2006, 2007, 2009, 2010, and 2011. The 

data for each sampling event is 

contained with each annual 

groundwater monitoring report and is 

included in the record for the proposed 

deletion. The area of the Site that 

included the parcels identified for 

delisting was located in the dry 

processing and parking areas of the 

former Eastland Woolen Mill. The 

NTCRA program resulted in the 

excavation and on-site treatment of any 

soils within the area identified for 

delisting. The table below documents 

that the NTCRA successfully treated the 

Site soil to levels that would allow for 

unrestricted use.

Operation and Maintenance 

Operation and maintenance activities 

for the parcels proposed for deletion 

include monitoring and maintenance of 

the institutional controls to ensure they 

effectively prohibit private well 

installation. In addition, the 

groundwater underlying these parcels 

continues to be monitored as part of the 

site-wide groundwater monitoring plan. 

Summary of the Data Documentation 

That the Deletion Criteria Have Been 

Met 

The OUI Record of Decision 

documented that the soil and surface 

water for the entire OUI area, including 

the properties proposed for deletion, do 

not represent an unacceptable threat to 

human health. The OUI Record of 

Decision identified groundwater as the 

only remaining threat to human health 

after the NTCRA. Groundwater 

discharge to surface water was the only 

ecological threat identified for the OUI. 

The supporting data for the 

characterization of the area to be 

delisted can be found in both the RI 

Report and NTCRA Documentation. In 

addition, long-term groundwater 

monitoring data documents that the 

properties proposed for deletion do not 

contain groundwater above the Sitespecific cleanup goals established in the 

2002 OUI ROD and 2006 OUI ROD 

Amendment. The properties proposed 

for deletion at the Eastland Woolen Mill 

Superfund Site do not contain soil or 

groundwater contamination above the 

Site specific cleanup levels. 

The properties proposed for deletion 

that are identified in the Town of 

Corinna subdivision plan as Lots 2, 3, 4, 

5, 6, 8, 9, and 10, portions of Lot 54 on 

Tax Map 18, the property identified as 

Lot 53 on Tax Map 18, and the property 

owned by Central Maine Power were 

not within the areas where substantial 

contamination was located. These 

properties contained open space, the 

dry processing portions of the former 

Eastland Woolen Mill, and office space. 

The concrete foundation where the dry 

processing of the woolen products was 

conducted was referred to as the ‘‘Slab 

Area’’ in the RI and NTCRA. 

As part of the OUI RI, five 

confirmation soil borings (SB–00–95 

through SB–00–99) were completed 

within Slab Area (see Figure 5–5 of the 

RI). One additional soil boring, (SB–01– 

106), was installed as part of the NTCRA 

by Weston in 2001. Table 5–3 of the RI 

provides a summary of volatile organic 

compounds (VOCs) detected in these 

Slab Area soil borings. Low levels of 

several VOCs were detected. The 

concentrations were below levels of 

concern for human contact. A 

monitoring well pair was installed to 

determine if the 1,1-dichloroethene 

detected in the soil was present in 

groundwater downgradient of the Slab 

area. VOCs were not detected in 

groundwater downgradient of the Slab, 

confirming that this area was not a 

significant source of groundwater 

contamination. 

The Slab was not removed until after 

the ex-situ soil treatment phase of the 

NTCRA. Prior to the removal of the 

concrete pad, one sample was collected 

per 500 ft2 using an excavator bucket to 

access the soil located below the 

concrete pad. A few areas with 

petroleum contamination were 

identified, and these soils were removed 

to allow for Site restoration. A total of 

176 samples were collected prior to 

concrete pad removal. A map showing 


sroberts on DSK5SPTVN1PROD with RULES
45976 Federal Register / Vol. 77, No. 149 / Thursday, August 2, 2012 / Rules and Regulations 

the locations of these samples is 

presented in Figure 17 of Appendix J in 

the November 2006 Final Overall 

Completion Report for the NTCRA, and 

analytical results are presented in Table 

27 of this report. All of the results from 

these initial 176 samples collected prior 

to the concrete pad removal confirmed 

that the soil concentrations were below 

the Site-specific cleanup levels. An 

additional five locations were sampled 

and characterized during concrete pad 

and footer wall removal due to staining 

or suspected contamination in the soil. 

Samples were analyzed for VOCs, DRO, 

polychlorinated biphenyls and/or 

metals based on the type and location of 

the staining. A summary of analytical 

results is shown in Table 28 of 

Appendix J in the November 2006 Final 

Overall Completion Report for the 

NTCRA, and sample locations are 

shown in Figure 18 of this report. Three 

of these locations contained Diesel 

Range Organic contamination. The 

contamination was removed because the 

soil was in an area where grading was 

necessary. 

In addition to the Slab Area, a portion 

of the properties to be deleted were used 

to store contaminated soil in a stockpile 

prior to treatment. After completion of 

the treatment of the contaminated soil, 

22 soil samples were collected below 

the contaminated soil stockpile to verify 

that the soil did not contain the COCs 

at levels above the site cleanup levels. 

A map detailing sample locations 

within the stockpile footprint is shown 

in Figure 16 of Appendix J in the 

November 2006 Final Overall 

Completion Report for the NTCRA. The 

analytical results for all samples 

collected from the below the stockpile 

footprint are presented in Table 26 of 

this report. Sample location 21, initially 

sampled on 9 October 2003, showed 

1,2,4-TCB at levels above the Site 

specifc soil excavation goal of 5,000 

microgram per kilogram (mg/kg). 

Therefore, a 6-inch layer of soil was 

removed from this grid of the stockpile 

footprint and processed through the 

LTTT system. A subsequent sample of 

this location was collected on 10 

October 2003. Results from this sample 

were well below Site specific cleanup 

levels. 

In summary, the Town of Corinna 

subdivision lots 2, 3, 4, 5, 6, 8, 9, and 

10, the portion of Subdivision Lot 1 

north of the Central Maine Power 

property, a portion of Lot 54 on Tax 

Map 18, the property identified at Map 

18 Lot 53 (Winchester Park) and the 

property owned by Central Maine Power 

have been evaluated during the RI and 

NTCRA activities. The RI documented 

that the area was not a substantial threat 

to groundwater. The NTCRA sampling 

further documented that these 

properties do not contain soil 

contamination above the Site specific 

cleanup levels. 

Portions of the property owned by the 

State of Maine Department of 

Transportation, State of Maine 

Department of Conservation, and the 

Town of Corinna property described in 

Quitclaim Deed dated August 18, 1997 

and recorded in Book 6471, Page 278, 

also identified as Lot 118 in Tax Map 18 

dated 2004 were within the area subject 

to the excavation of contaminated soil 

and sediment as part of the NTCRA. 

A portion of the State of Maine 

Department of Conservation property 

crossed the former Eastland Woolen 

Mill property near the area known as 

the pump house. The soil excavation 

and cleanup confirmation for this area 

can be found in Appendix H of the 

November 2006 Final Overall 

Completion Report for the NTCRA.

A portion of the State of Maine 

Department of Transportation, State of 

Maine Department of Conservation, and 

Town of Corinna properties included 

the East Branch of the Sebasticook 

River. Appendix G in the November 

2006 Final Overall Completion Report

through A–4B and Tables B–7 and B–8 

of Appendix G show the location and 

data that document that the cleanup was 

successful for these properties. 

In summary, the property owned by 

the State of Maine Department of 

Transportation, State of Maine 

Department of Conservation, and the 

Town of Corinna property described in 

Quitclaim Deed dated August 18, 1997 

and recorded in Book 6471, Page 278, 

also identified as Lot 118 in Tax Map 18 

dated 2012 that are proposed for delisting no longer contain contamination 

above the Site specific cleanup levels as 

documented by the completion report 

for the NTCRA. 

Five-Year Review 

The assessment of the first five-year 

review performed in 2010 found that the 

remedy was constructed in accordance 

with the requirements of the Record of 

Decision (ROD) issued in 2002 and 

amended in 2006. The LTRA remedy is 

functioning as designed. As a result of 

the response actions at the Site, there is 

no current exposure to contaminants at 

the Site. A water line provides clean 

water and planned ICs will ensure 

appropriate future use of potentially 

contaminated groundwater. The remedy 

at the Eastland Woolen Mill Superfund 

Site currently protects human health 

and the environment because the 

contamination accessible to ecological 

receptors has been removed, there is no 

current human exposure to 

contamination, the groundwater 

contamination is not migrating, clean 

water is available to all locations within 

the extent of the groundwater 

contamination, and EPA is actively 

treating and monitoring the 

groundwater as part of the on-going 

Long-Term Response Action. However, 

in order for the remedy to be protective 

in the long-term, the institutional 

controls to prevent future groundwater 

use need to be in place to ensure longterm protectiveness. As part of this fiveyear review, a preliminary assessment of 

the potential for vapor intrusion to 

present a threat at the Site was 

performed. There are no structures 

above areas of the plume that exceed 

vapor intrusion screening criteria, so the 

pathway is not complete. Further 

investigations regarding the vapor 

intrusion pathway will be completed 

prior to the next five-year review. 

Further investigation regarding the 

vapor intrusion pathway will be 

completed on properties that are not 

subject to the partial deletion. 

Since the completion of the five-year 

review, the institutional controls, that 

are in the form of environmental 

covenants, have been completed for the 

properties that will remain within the 

Site and the properties that are 

proposed for deletion. The only 

institutional controls that remain to be 


sroberts on DSK5SPTVN1PROD with RULES
Federal Register / Vol. 77, No. 149 / Thursday, August 2, 2012 / Rules and Regulations 45977 

completed are for properties that are offsite. The groundwater under these 

remaining properties is not 

contaminated but a pumping well on 

these properties could cause the 

contaminated groundwater plume to 

expand. In addition, the properties 

proposed for deletion are not in the area 

where the vapor intrusion evaluation is 

being re-evaluated. The ICs for the 

properties proposed for deletion and the 

properties that will remain within the 

boundaries of the Site were signed in 

May 2012 and recorded in June 5, 2012. 

The next five-year review will take 

place in 2015. 

Community Involvement 

Throughout the EPA cleanup of the 

Site, community concern and 

involvement has been high. The local 

Selectboard actively sought EPA’s 

involvement at the Site to address the 

contamination left behind by the closure 

of the mill in 1996. EPA has kept the 

community and other interested parties 

informed of Site activities through 

informational meetings, fact sheets, 

press releases and public meetings. 

Information about the Site is posted on 

EPA’s Web site. EPA has met regularly 

with the community and Selectboard to 

keep them informed and to seek their 

input regarding Site activities. The 

community has also benefited from a 

Web site (www.cattailpress.com), which 

was developed and is maintained by a 

local resident. The Web site contained 

daily photographs of Site activities 

during the NTCRA demolition and 

excavation activities and has provided a 

forum for community dialogue 

regarding the Site. EPA’s public notices 

and fact sheets have been posted on this 

Web site as well. EPA provided the 

community with a Technical Assistance 

Grant (TAG) and a Redevelopment Pilot 

Grant. EPA identified the potential for 

partial delisting of the Eastland Woolen 

Mill in a community update issues in 

2006. EPA issues a fact sheet in 2010 to 

announce the performance of the Five 

Year Review. EPA met with the 

community in May 2010 to discuss the 

Site status and Five Year Review. All 

Community Involvement activities 

required and associated with this 

proposed partial deletion have been 

completed, including the publication of 

a notice in a local newspaper of general 

circulation regarding this proposed 

deletion and the availability of 

documents located in the Deletion 

Docket. 

Determination That the Criteria for 

Deletion Have Been Met 

The NCP specifies that EPA may 

delete a site from the NPL if ‘‘all 

appropriate responsible parties or other 

persons have implemented all 

appropriate response actions required’’ 

or ‘‘all appropriate fund-financed 

response under CERCLA has been 

implemented, and no further response 

action by responsible parties is 

appropriate’’ or ‘‘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’’. For the 

partial deletion proposed at the Eastland 

Woolen Mill Superfund Site: 

• All appropriate Fund-financed 

response under CERCLA has been 

implemented, and no further response 

action by responsible parties is 

appropriate; as required by 40 CFR 

300.425(e)(1)(ii). An Interim Remedial 

Action Report was completed in 2008 to 

document the completion of the 

Remedial Action activities, including 

the area subject to de-listing. 

EPA, with the concurrence of the State 

of Maine through the Maine DEP by a 

letter dated June 14, 2012, believes these 

criteria for deletion have been satisfied. 

Therefore, EPA is proposing the 

deletion of certain properties at the site 

from the NPL. All of the completion 

requirements for the properties 

proposed for deletion at the Site have 

been met. 

V. Partial Deletion Action 

The EPA, with concurrence of the 

State of Maine through the Maine 

Department of Environmental 

Protection, on June 14, 2012, has 

determined that all appropriate 

response actions under CERCLA have 

been completed for the properties 

proposed for deletion. Therefore, EPA is 

deleting the following properties: 

Properties owned by the Town of Corinna 

that include properties described in 

Quitclaim Deed dated August 18, 1997 and 

recorded in Book 6471, Page 278, also 

identified as Lot 118 in Tax Map 18 dated 

2004 and several additional properties that 

were part of the former Eastland Woolen Mill 

complex that were acquired due to a tax 

foreclosure. The tax foreclosure properties 

are described in the Penobscot County 

Registry of Deeds in Condemnation Order 

dated December 8, 1999 and recorded in 

Book 7251, Page 47 and a portion of the 

property has been subdivided in accordance 

with a plan dated October 19, 2004 entitled, 

‘‘Subdivision Plan for the Town of Corinna 

of Main Street Subdivision on Main Street, 

Hill Street & St. Albans Road in Corinna, 

County of Penobscot, Maine,’’ recorded in 

said Registry in Plan File 2004, No. 167 (the 

‘‘Subdivision Plan’’). Specifically, 

subdivision Lots 2, 3, 4, 5, 6, 8, 9, 10, the 

portion of Subdivision Lot 1 north of the 

Central Maine Power property, and a portion 

of Lot 54 on Tax Map 18, along with Lot 53 

on Tax Map 18, are proposed for deletion. 

The portions of Main Street and Hill Street 

within the subdivision are also proposed for 

deletion. Lot 53 on Tax Map 18 is also 

recorded in Book 853, Page 391, as a 

warranty deed dated September 26, 1913 and 

is known as ‘‘Winchester Park’’. 

Property owned by the State of Maine 

Department of Conservation identified in 

Release Deed dated December 5, 2003 Book 

9114, Page 194, also identified in Tax Map 

18 as Map 15 Lot 10 (which a portion of the 

State of Maine Department of Conservation 

recreational trail that runs through the Town 

of Corinna). 

Property owned by the State of Maine 

Department of Transportation described in a 

Notice of Layout and Taking dated May 3, 

2000, and recorded in the Penobscot County 

Registry of Deeds in Book 7357, Page 29, and 

being generally depicted on the Survey Plan 

Showing Property Subject to Proposed 

Environmental Covenants for Maine 

Department of Environmental Protection, 

Corinna, Penobscot County, Maine which is 

recorded in the Penobscot County Registry of 

Deeds as Plan File 2012 No. 20 dated March 

29, 2012, but excluding the portion of the 

Maine Department of Transportation 

property bounded by Town of Corinna 

Subdivision Lot 1, the East Branch of the 

Sebasticook River, Route 7, and Nokomis 

Road. 

Property owned by Central Maine Power 

identified in indenture dated May 2, 1956 

and recorded in the Penobscot County 

Registry of Deeds in Book 1532, Page 228, 

and generally depicted as Central Maine 

Power Company land in the Town of Corinna 

tax records as Lot 4 on Tax Map 20. 

Because EPA considers this action to 

be noncontroversial and routine, EPA is 

taking it without prior publication. This 

action will be effective October 1, 2012 

unless EPA receives adverse comments 

by September 4, 2012. 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.
