been completed at the Site other than

O&M and five-year reviews.

E. Community Involvement

Public participation activities have

been satisfied as required by CERCLA

section 113(k), 42 U.S.C. 9613(k), and

CERCLA section 117, 42 U.S.C. 9617.

Documents in the deletion docket which

EPA relied on for its decision to delete

the Site from the NPL are available to

the public at the information

repositories.

V. Deletion Action

The EPA, with concurrence of the

NMED, has determined that responsible

parties have implemented all

appropriate response actions required at

the Site and that no further response

actions, under CERCLA, other than

O&M and five-year reviews, are

necessary. Therefore, EPA is deleting

the Site from the NPL.

Because EPA considers this action to

be noncontroversial and routine, EPA is

taking it without prior publication of a

notice of intent to delete. This action

will be effective July 23, 2001 unless

EPA receives adverse comments by June

21, 2001. If adverse comments are

received within the 30-day public

comment period, EPA will publish a

timely withdrawal of this direct final

deletion before the effective date of the

deletion and it will not take effect and

EPA will prepare a response to

comments and continue with the

deletion process on the basis of the

notice of intent to delete and the

comments already received. There will

be no additional opportunity to

comment.

ACTION: Direct Final Deletion of the

Brodhead Creek Superfund Site from

the National Priorities List.

SUMMARY: The Environmental Protection

Agency (EPA) Region III is publishing a

direct final deletion of the Brodhead

Creek Superfund Site (Site) located in

the Borough of Stroudsburg, Monroe

County, Pennsylvania, 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

Appendix B of 40 CFR Part 300, which

is the National Oil and Hazardous

Substances Pollution Contingency Plan

(NCP). This direct final deletion is being

published by EPA with the concurrence

of the Commonwealth of Pennsylvania,

through the Pennsylvania Department of

Environmental Protection (PADEP)

because EPA has determined that all

appropriate response actions under

CERCLA have been completed and,

therefore, further remedial action

pursuant to CERCLA is not appropriate.

DATES: This direct final deletion will be

effective July 23, 2001, unless EPA

receives adverse comments by June 21,

2001. If adverse comments are received,

EPA will publish a timely withdrawal of

the direct final deletion in the Federal

Register informing the public that the

deletion will not take effect.

IV. Basis for Site Deletion

I. Deletion Action

I. Introduction

EPA Region III is publishing this

direct final deletion of the Brodhead

Creek Superfund Site from the NPL.

The EPA identifies sites that appear to

present a significant risk to public

health or the environment and

maintains the NPL as the list of those

sites. As described in § 300.425(e)(3) of

the NCP, sites deleted from the NPL

remain eligible for remedial actions if

conditions at a deleted site warrant such

action.

Because EPA considers this action to

be noncontroversial and routine, EPA is

taking it without prior publication of a

notice of intent to delete. This action

will be effective July 23, 2001 unless

EPA receives adverse comments by June

21, 2001. If adverse comments are

received within the 30-day public

comment period on this document, EPA

will publish a timely withdrawal of this

direct final deletion before the effective

date of the deletion and the 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 to delete 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 Brodhead Creek

Superfund Site and demonstrates how it

meets the deletion criteria. Section V

28100 Federal Register / Vol. 66, No. 99 / Tuesday, May 22, 2001 / Rules and Regulations

discusses EPA’s action to delete the Site

from the NPL unless adverse comments

are received during the public comment

period.

II. NPL Deletion Criteria

Section 300.425(e) of the NCP

provides that releases may be deleted

from the NPL where no further response

is appropriate. In making a

determination to delete a release from

the NPL, EPA shall 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

(Hazardous Substance Superfund

Response Trust Fund) 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.

Even if a site is deleted from the NPL,

where hazardous substances, pollutants,

or contaminants remain at the deleted

site above levels that allow for

unlimited use and unrestricted

exposure, CERCLA Section 121(c), 42

U.S.C. 9621(c) requires that a

subsequent review of the site be

conducted at least every five years after

the initiation of the remedial action at

the deleted site to ensure that the action

remains protective of public health and

the environment. If new information

becomes available which indicates a

need for further action, EPA may initiate

remedial actions. 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. Deletion Procedures

The following procedures apply to

deletion of the Site:

(1) The EPA consulted with the

Commonwealth of Pennsylvania on the

deletion of the Site from the NPL prior

to developing this direct final deletion.

(2) The Commonwealth of

Pennsylvania concurred with the

deletion of the Site from the NPL.

(3) Concurrently with the publication

of this direct final deletion, a notice of

the availability of the parallel notice of

intent to delete published today in the

‘‘Proposed Rules’’ section of the Federal

Register is being published in a major

local newspaper of general circulation at

or near the Site and is being distributed

to the appropriate federal, state, and

local government officials and other

interested parties; the newspaper notice

announces the 30-day public comment

period concerning the notice of intent to

delete the Site from the NPL.

(4) The EPA placed copies of

documents supporting the deletion in

the Site information repositories

identified above.

(5) If adverse comments are received

within the 30-day public comment

period on this document, EPA will

publish a timely withdrawal of this

direct final 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 to delete and the

comments already received.

Deletion of a Site from the NPL does

not itself create, alter, or revoke any

individual’s rights or obligations.

Deletion 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 future response actions,

should future conditions warrant such

action.

IV. Basis for Site Deletion

The following information provides

EPA’s rationale for deleting the Site

from the NPL:

A. Site Location

The Brodhead Creek Site occupies

approximately 12 acres of a flood plain

area on the western bank of Brodhead

Creek at the confluence of Brodhead

Creek and McMichael Creek in the

Borough of Stroudsburg in Monroe

County, Pennsylvania.

B. Site History

The Site is the former location of a

coal gasification plant which operated

from approximately 1888 to 1944. A

waste product from these operations

was a black tar-like liquid (‘‘coal tar’’)

which has a density greater than water

and which is principally composed of

polynuclear aromatic hydrocarbons

(‘‘PAHs’’). The coal tar was placed in an

open pit located on the Site. This

practice continued to the mid-1940s

when the plant was abandoned.

On October 7, 1980, during

construction repairs to the flood control

levee at the Site, materials identified as

coal tar were observed seeping into

Brodhead Creek. As a result, several

investigations and emergency response

measures were initiated by EPA,

PADEP, and Pennsylvania Power and

Light Company (PP&L) from 1981

through 1984, including: (1) Installation

of temporary filter fences and underflow

dams to intercept coal tar seepage; (2)

installation of a temporary coal tar

recovery pit on the west bank of

Brodhead Creek; (3) construction of a

slurry wall by EPA to mitigate coal tar

migration from the Site toward

Brodhead Creek; (4) excavation of a

backwater channel area where coal tar

seepage appeared to be particularly

significant; and (5) installation of

recovery wells in the main coal tar pool

by PP&L, with the subsequent recovery

of approximately 8,000 gallons of coal

tar.

The Site was placed on the NPL in

December 1982, with a Hazard Ranking

Score of 31.09.

Remedial Investigation and Feasibility

Study (RI/FS)

On August 20, 1987, PP&L and Union

Gas Company (UGC) entered into a

Consent Order and Agreement with the

Commonwealth of Pennsylvania to

conduct the original remedial

investigation and feasibility study (RI/

FS) for the Brodhead Creek Site. The

original RI/FS was completed in 1991.

The results of the original RI

indicated that coal tar from the former

coal gasification operations had

migrated vertically through the

unsaturated and saturated portions of

the stream gravel unit underlying the

Site to the interface with the silty sand.

The silty sand prevents further

downward movement of the coal tar

because of the higher capillary pressures

within that unit. Approximately 4.28

acres of the gravel unit at the Site were

contaminated with free and residual

coal tar. The free coal tar (i.e., coal tar

at 100% pore volume saturation) is

limited to a small area of a stratigraphic

depression east of the slurry wall near

monitoring well MW–2 (the MW–2

Area) and to the lowest portion of the

stratigraphic depression located west of

the slurry wall (the RCC Area). Both of

these free coal tar accumulations are

confined from further downward

migration by the top of the silty sand

unit. Residual coal tar (i.e., coal tar at

less than 100% pore volume saturation)

can be found throughout the remainder

of the 4.28 acres.

The total volume of free coal tar at the

Site was estimated to be 9,000 gallons,

8,715 gallons at the RCC Area and 338

gallons at the MW–2 Area. The extent of

residual coal tar contamination at the

Site was estimated to be from 303,000

gallons to 409,000 gallons.

Characterization of Risk

The risk assessment in the original RI

identified PAHs, benzene, and arsenic

Federal Register / Vol. 66, No. 99 / Tuesday, May 22, 2001 / Rules and Regulations 28101

as the primary contaminants of concern

at the Site. Federal Maximum

Contaminant Levels (MCLs) for drinking

water established pursuant to the Safe

Drinking Water Act, 42 U.S.C. 300f et

seq., were exceeded for arsenic,

benzene, and benzo(a)pyrene in the

subsurface gravel unit. Proposed MCLs

were exceeded in the ground water in

the gravel unit for the following PAHs:

benzo(a)anthracene;

benzo(b)fluoranthene;

benzo(k)fluoranthene; chrysene,

dibenz(a,h)anthracene; and

indenopyrene. These PAHs, as well as

arsenic and benzene, are ‘‘hazardous

substances’’ as defined in Section

101(14) of CERCLA.

After reviewing the results of the

original RI/FS, EPA divided the

remedial work to be undertaken at the

Site into two operable units (‘‘OUs’’).

These were as follows:

OU–1: Contaminated subsurface soils

containing free coal tar in the stream

gravel unit

OU–2: Ground water in the stream

gravel unit to and including bedrock

EPA determined that an interim

remedial action should be taken for OU–

1 to initiate reduction of the toxicity,

mobility, and volume of contaminants

in the stream gravel unit at the Site. The

interim remedial action would entail the

removal of the free coal tar from the

stream gravel unit. The free coal tar was

a principal threat to human health and

the environment since it imparted high

levels of contaminants to the ground

water in the stream gravel unit and

could serve as a potential source of

release of contamination to the ground

water in bedrock. Implementation of an

interim remedial action would remove

the source of the highest level of

contamination and would reduce

further leaching of contaminants into

the ground water. Data generated during

the implementation of the interim

action and further investigations for

OU–2 would provide the information

necessary to assist EPA in determining

whether (and where) restoration of

ground water to beneficial use was

feasible. This in turn would enable EPA

to issue a final Record of Decision for

the Brodhead Creek Site.

Record of Decision Findings for OU–1

In a Record of Decision (ROD) issued

on March 29, 1991, EPA selected an

interim remedial action for OU–1 which

included the following major

components:

—Recovery of free coal tar from the

subsurface soils utilizing the

innovative technology of enhanced

recovery (referred to as the Contained

Recovery of Oily Waste (CROW)

process);

—Disposal of the recovered coal tar at

an off-site permitted facility;

—Imposition of institutional controls to

limit future use of the Site; and

—Monitoring of ground water and biota

in Brodhead Creek to ensure

protection of human health and the

environment.

Response Actions for OU–1

On September 2, 1992, EPA, PP&L

and UGC entered into a Consent Decree

under which the companies agreed to

implement the remedial design/

remedial action (RD/RA) for OU–1 at the

Site. The original performance standard

in the ROD required that at least 60%

of the free coal tar in the subsurface

soils be removed. On July 14, 1994, EPA

issued an Explanation of Significant

Differences (ESD) which revised the

performance standard in the ROD by

requiring the operation of the CROW

process until the increase in cumulative

recovery of the coal tar dropped to 0.5%

or less per pore volume flushed through

the formation. This revision of the

performance standard was based on

EPA’s determination that accurate

measurement of the removal of 60% of

the free coal tar would not be possible

because of the geology of the Site and

the nature of the subsurface coal tar

contamination. By June of 1996,

approximately 1,500 total gallons of coal

tar had been removed from the RCC

Area and the performance standard had

been met.

EPA determined during the CROW

operational period that it would not be

practical to implement CROW at the

MW–2 Area (the area located at

monitoring well MW–2) since the MW–

2 Area contained only a small amount

of free coal tar. Instead, EPA determined

that the relatively minor amount of coal

tar in the MW–2 Area wells should be

removed via intermittent pumping.

Approximately 100.5 gallons of coal tar

were recovered from the MW–2 Area

between February 1996 and March

1997.

Because of the variable nature of the

coal tar recovery effort at the MW–2

wells, EPA determined that continued

active intermittent pumping of the MW–

2 wells could be suspended. However,

as part of operation and maintenance of

the Site, EPA has required that the MW–

2 wells, and any wells in the RCC Area

that have historically contained coal tar,

be monitored for a free coal tar surface

as part of the long-term ground water

monitoring requirement at the Site. If a

coal tar layer greater than six inches is

discovered, it will be removed by

pumping at that time.

These changes for the MW–2 Area

were documented in a second

Explanation of Significant Differences

dated September 30, 1997. This second

ESD also converted the interim remedy

in the ROD for OU–1 into the final

remedy for the Site and described the

long-term monitoring strategy for the

Site.

Record of Decision Findings for OU–2

On June 3, 1992, EPA, PP&L and UGC

entered into a Consent Order under

which the companies agreed to conduct

a Focused RI/FS for OU–2 to further

investigate ground water contamination

at the Site. On June 30, 1995, EPA

issued a ROD for OU–2 at the Brodhead

Creek Site. This ROD addressed ground

water contamination and residual coal

tar contamination in the subsurface

soils. In the ROD for OU–2, EPA

selected a No Further Action alternative

and established a technical

impracticability (‘‘TI’’) zone within

which the Agency determined it would

be impracticable to remediate ground

water and residual coal tar

contamination. EPA waived federal

MCLs and Pennsylvania’s Applicable or

Relevant and Appropriate Requirement

(ARAR) for cleanup to ‘‘background’’

levels of contamination on the basis of

‘‘Technical Impracticability.’’ Several

Site-specific constraints made the

implementation of engineering solutions

to the residual coal tar contamination

impracticable. As stated in the OU–2

ROD, these included: (1) the need to

temporarily reroute Brodhead Creek to

access coal tar-impacted soils beneath

the creek bed; (2) the need to reinforce

the existing interstate I–80 bridge

abutments in order to protect them from

the increased velocity and height of the

creek which would result from rerouting

the creek; and (3) the need to restore

wetlands which would be impacted by

any remediation alternative. In addition,

the existing earthen levee which

currently bisects the Site, and which

protects the Borough of Stroudsburg and

the slurry wall installed by EPA as an

emergency action in the early 1980s,

would probably sustain damage from

the implementation of any engineering

alternative, and require repair.

In the ROD for OU–2, EPA

determined that the No Further Action

alternative, in conjunction with the OU–

1 selected remedy, is protective of

human health and the environment.

Implementation of the OU–1 enhanced

recovery program for the free coal tar

areas on-site reduced the areas of

highest subsurface soil contamination.

The OU–1 monitoring program will

provide the data required to evaluate the

fate of the coal tar-related constituents,

28102 Federal Register / Vol. 66, No. 99 / Tuesday, May 22, 2001 / Rules and Regulations

the integrity of the slurry wall and the

‘‘health’’ of the biological community in

Brodhead Creek. This will provide long

term protection against the unlikely

event that Site conditions might change

and potential exposures increase. In

addition, the slurry wall installed at the

Site will continue to prevent free coal

tar from discharging to Brodhead Creek.

C. Future Activity

Operation and Maintenance

Operation and Maintenance (O&M)

activities, which are performed by

PP&L(now known as PPL Electric

Utilities Corporation (PPL)) with EPA

oversight, include periodic inspections,

ground water monitoring, stream

sediment and biota monitoring, and the

removal of relatively minor amounts of

free coal tar from the two

stratigraphically isolated areas of the

Site, as necessary, but no less often than

annually, and any other activities

necessary to ensure continued

protection of public health and the

environment. The free coal tar removal,

in conjunction with long-term ground

water monitoring, will continue to

ensure the effectiveness of the

completed remedy at the Brodhead

Creek Site.

Five-Year Review

CERCLA requires a five-year review of

all sites with hazardous substances

remaining above the health based levels

for unrestricted use of the Site. Since

residual coal tar contamination and

ground water contamination remain at

the Site, the five-year review process

will be used to ensure that the selected

remedy continues to be protective of

human health and the environment.

EPA completed the first five-year review

of the Brodhead Creek Site on May 28,

1999. In that five-year review, EPA

determined that the remedy was not

completely protective of human health

and the environment because

institutional controls on future land use

at the Site had not yet been

implemented. On September 22, 2000,

institutional controls which limit future

land use at the Brodhead Creek Site

were implemented by PPL and UGC

(now known as PFG Gas, Inc.), and

recorded at the Monroe County

Courthouse, Recorder of Deeds Office,

in Stroudsburg, Pennsylvania. These

controls include restricting use of

ground water at the Site and prohibiting

excavation at the Site unless prior

written approval is provided by the

property owner, EPA, and PADEP.

These institutional controls will

reinforce the protectiveness of the

selected remedy. EPA has determined

that all requirements of the ROD for

OU–1, as modified by the ESDs dated

July 14, 1994 and September 30, 1997,

have been achieved at the Site and the

Site is protective of human health and

the environment. EPA plans to complete

the next five year review prior to May

28, 2004.

D. Community Involvement

Public participation activities have

been satisfied as required in CERCLA

Section 113(k), 42 U.S.C. 9613(k), and

CERCLA Section 117, 42 U.S.C 9617.

Documents in the deletion docket which

EPA relied on for recommendation of

the deletion from the NPL are available

to the public in the information

repositories.

V. Deletion Action

The EPA, with the concurrence of the

Commonwealth of Pennsylvania, has

determined that all appropriate

responses under CERCLA have been

completed, and that no further response

actions, under CERCLA, other than

O&M and five-year reviews, are

necessary. Therefore, EPA is deleting

the Site from the NPL.

Because EPA considers this action to

be noncontroversial and routine, EPA is

taking it without prior publication of a

notice of intent to delete. This action

will be effective July 23, 2001 unless

EPA receives adverse comments by June

21, 2001 on this document. If adverse

comments are received within the 30-

day public comment period on this

document to delete, EPA will publish a

timely withdrawal of this direct final

deletion before the effective date of the

deletion and the deletion 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 delete and the

comments already received. There will

be no additional opportunity to

comment.
