Background

The American Creosote Works (ACW) Superfund Site is located in Winnfield, Winn Parish, Louisiana. The
ACW Site is about 34 acres in size, and it is bordered by Front Street on the west and Watts and Grove
Streets on the south. The Site is bounded on the north and east by Creosote Branch creek.

Wood treatment operations at the ACW Site began in 1901, when the Site was operated by the Bodcaw
Lumber Company. In 1938, the ACW
Site was purchased by American
Creosote Works of Louisiana, Inc. (later
to become American Creosote Works,

Inc.), which operated the facility until
1977. Wood treatment operations at the
Site utilized both creosote and
pentachlorophenol (PCP). Petroleum
products were also used as a carrier fluid
for the creosote and PCP. By 1979, it
appears that wood treating operations at
the ACW Site had ceased. The site
owner, Dickerson Lumber Company,
declared bankruptcy during this time
period, and the City of Winnfieid seized
the property for failure to pay taxes. The
Site was eventually purchased by

Stallworth Timber Company, and by 1981, wood treating operations resumed at the Site on a smaller
scale.

The LDEQ conducted several inspections at the Site between 1982 and 1986. These inspections noted
spillage of creosote, abandoned pits and containers, and obvious offsite contamination. LDEQ issued a
letter of warning to Stallworth Timber Company in January 1983. In December 1984, LDEQ inspectors
noted no improvements at the Site, and issued a Compliance Order. Stallworth Timber Company failed to
comply with the terms of the Compliance Order, and in June 1985, LDEQ inspectors found the Site
abandoned.

The LDEQ referred the ACW Site to EPA in March 1987. The EPA conducted several investigations at the
Site and in May 1988 issued a Unilateral Administrative Order (UAO) to construct a fence and post
warning signs around the most contaminated portions of the Site. Stallworth Timber Company completed
this task in July 1988. During this action, an EPA contractor noted two storage tanks at the Site that were

in imminent danger of rupturing, EPA notified Stailworth Timber Company of this threat, but the company
declined taking action. The EPA conducted an emergency removal action at the ACW Site in June 1988.
This involved draining the tank, constructing a berm around the process area to contain and stabilize
heavily contaminated soils, and installing an overflow filtration system. In February 1989, Stailworth
Timber Company again declined to take action in response to the UAO. The EPA conducted another
emergency removal action at the ACW Site to address the immediate, short-term risks posed by the Site.
All wood treating liquids at the Site were consolidated into a single tank. Liquid and surface sludges at the
Site were solidified, and the stabilized material was consolidated into an existing impoundment. Existing
buildings and process equipment were dismantled and decontaminated. A drainage ditch was constructed
and contaminated water was treated and discharged to Creosote Branch creek. In December 1991,
Stailworth Timber Company notified the EPA that the property had been sold to Reinhardt Investments
(located in the Netherlands Antilles). The EPA received no response to its inquiries to Reinhardt
Investments.

The Site is currently comprised of two land parcels. The south parcel, which is owned and controlled by
Winn Parish, is inactive.. The north parcel is also owned by Winn Parish, but the property is under the
control of the EPA through an access agreement. The north parcel is separated from the south parcel and
completely enclosed by a security fence. A fluids recovery system, numerous monitor wells, a fluids
injection system, and the Process Liquids Treatment Facility (PLTS) are located on the north parcel. Two
waste burial areas are also located on the north parcel.

The contaminants of concern are carcinogenic polynuclear aromatic hydrocarbons (CPAH's),
Pentachlorophenol (PCP), volatile organic compounds (VOCs), and dioxins.

The City of Winnfield has a population of approximately 7,000 residents. Land use in the ACW Site area
includes agricultural, residential, and recreational uses. Agricultural uses are localized and occur in areas
between forested land and residential development. Forests in the area are used primarily for timber
production. Forest lands also support recreational uses including hunting, fishing, camping, and hiking.
The Site is surrounded by residential neighborhoods, with the closest residence being located 200 feet
from the Site. Most of the residents use the Winnfield Water System as their source of potable water.

The ROD for the ACW Site was signed on April 28, 1993.The Site was also addressed through two
emergency response actions. The remedy described in the 1993 ROD for the ACW Site included the
following elements:

-	Liquid contaminants were to be pumped from the subsurface, separated, treated, and destroyed . -
Contaminated tars and sludges would be incinerated onsite. The resulting incinerator ash would be
returned to the excavated areas and used to backfill the excavations. The backfilled excavations would be
graded, capped with soil, and revegetated.

-	Contaminated soils and sludges would be addressed through in-situ biological treatment.

-	Capping of contaminated surface soils, decontamination and onsite landfiiling of process equipment and
scrap, and grading and capping to complement the above remedial actions.

-	Ecological monitoring for an estimated period of 5 to 10 years.

-	Ground water monitoring to occur for 5 to 10 years.

permitted outfall.

•	EPA continues to monitor the performance of the remedy to assess its effectiveness in achieving
the established remedial objectives.

•	A Third Five Year Review of the remedial action was completed on May 19, 2010. The remedy
was found to be protective of human health and the environment.

•	EPA has initiated a ground water tracer survey in order to determine specific ground water flow
paths. This will aid in maximizing the removal capacity of the ground water recovery system.

Benefits

The $17 million remedial action boosted local employment during the cleanup by utilizing local
labor. The prime contractor also utilized several area vendors. Local vendors were identified
during the bid specification stage utilizing the Chamber of Commerce to identify area expertise.
The completion of the in-situ bioremediation system has effectively eliminated discharges to
Creosote Branch Creek, allowing the stream to recover to natural conditions.

EPA is working with the City of Winnfield to transition the site to industrial use. Currently about a
third of the site is being reused by a local construction firm.
