1 mile northeast of Port Jervis

Site Description 	

The Carroll and Dubies Sewage Disposal site was made up of seven inactive lagoons that were used
for the disposal of various wastes since about 1970. Until 1979, waste from two nearby cosmetic
manufacturers was deposited into unlined lagoons at the site. Septic tank waste also was accepted at
the site until 1989. Five of the seven lagoons were filled, covered, and graded. The two uncovered
lagoons were fenced. Approximately 2,000 residents live within a mile of the site. The nearest
homes are about 1/4 mile southeast of the site. A steep slope, woods, open areas and the Port Jervis
Municipal Landfill surround the facility. The City of Port Jervis is supplied with water from several
reservoirs located more than a mile upstream from the site. Homes near the site rely on private wells.
Approximately 1,500 feet to the east of the site is Gold Creek, which lies between the site and the
Neversink River.

Site Responsibility: This site is being addressed through

Federal and potentially responsible party
(PRP) actions.

Threats and Contaminants

On-site groundwater is contaminated with volatile organic compounds (VOCs) as well as
some chlorinated VOCs. Potential threats to human health included drinking
contaminated groundwater, however, this threat will be addressed by the implementation
of institutional controls to restrict the use and installation of groundwater wells
throughout the contaminated groundwater plume. Implementation of institutional
controls will be completed by June 2002. Environmental investigations conducted
indicate that residential wells located downgradient of the site are not threatened by site
contamination.

Cleanup Approach

This site is being addressed in two long-term remedial phases focusing on cleanup of the source areas
and the groundwater.

Response Action Status 	

f\ Source Areas: The source area investigations involved characterizing the nature and
extent of chemical compounds associated with the lagoons by obtaining soil and waste
samples. An investigation that determined the extent of the contamination of four
lagoons was completed in 1992. An investigation to determine the nature and extent of
contamination of three additional lagoons was completed in 1993. Based on the results of these
investigations, remedial alternatives were developed and a Record of Decision (ROD) selecting a
final cleanup plan for the source areas was signed in March 1995.

An Explanation of Significant Differences (ESD) was issued in August 1998. The ESD describes
changes to the March 1995 ROD. The changes described in the ESD include: 1) the excavation and
off-site treatment and disposal of approximately 13,300 tons of lagoon sludges and soil contaminated
with organic and inorganic contaminants; 2) in-situ soil vapor extraction to treat subsurface soils
impacted by volatile organic compounds, unless it is more practicable to excavate and dispose these
soils off-site; 3) on-site treatment of some contaminated soil and materials by ex-situ soil vapor
extraction prior to off-site disposal; and 4) backfilling and regrading of excavated areas with clean
soil.

On January 22, 1997 and December 3, 1998, EPA approved the Remedial Design workplan and
Remedial Action workplan for the source areas, respectively. The remedial action, which was
implemented by the PRPs, began in April 1999 and was completed in January 2000.

Groundwater: The groundwater investigation was conducted in two phases. The first phase of the
investigation was completed in 1992 and the purpose of the investigation was to identify the nature
and extent of the groundwater contamination on-site. The results of the Phase I investigation
indicated the need for implementation of the second phase of the investigation. The purpose of Phase
II was to determine whether off-site migration of contaminants through the groundwater had
occurred. The Phase II investigation revealed that significant levels of contaminants had not
migrated from the source areas. A Record of Decision selecting a final cleanup plan for the
contaminated groundwater was signed in September 1996 and included: natural attenuation of
organic contaminants in the groundwater; implementation of institutional controls to restrict the use
and installation of groundwater wells throughout the contaminated groundwater plume; monitoring of
the groundwater; and sampling in Gold Creek. The estimated volume of contaminated groundwater
at the site is not available.

Site Facts: In 1990, the EPA and two parties potentially responsible for the site contamination
entered into an Administrative Order on Consent requiring the parties to conduct an investigation to
characterize the nature and extent of contamination at the site and develop appropriate alternatives
for remediating the site. Record of Decisions selecting final cleanup plans for the source areas and
the groundwater were signed in March 1995 and September 1996, respectively. An ESD modifying
the remedy selected for the source areas was issued in August 1998. In May 1995 EPA issued
"special notice" letters to the potentially responsible parties requesting that they submit a good faith
offer to perform the Remedial Design/Remedial Action for the source areas. The parties and EPA
were unable to reach agreement; in September 1995, EPA issued a Unilateral Administrative Order to
the parties ordering them to implement the source areas remedy. In June 1997, EPA issued an
amended Unilateral Administrative Order to two of the parties ordering them to perform the natural
attenuation and monitoring remedy selected in the September 1996 ROD. EPA also issued a
Unilateral Administrative Order to the City of Port Jervis requiring that they cooperate and
coordinate with the other recipients of the Unilateral Administrative Order in implementing the
source areas and natural attenuation remedies.

Cleanup Progress

(Construction Complete)

The excavation and off-site disposal of approximately 34,000 tons of lagoon sludges, sediment and
contaminated soil, completed in January 2000, should mitigate the potential for further contamination
of the groundwater. Semi-annual groundwater monitoring will be conducted to ensure that the 1996
Natural Attenuation/ Institutional Control groundwater remedy remains protective. No further
construction activities are anticipated for the site.
