The Remediation Process
Abandoned wood treating facility operated from 1909 to 1984 under various owners.
Prior removal actions have controlled site runoff and restricted public access
During the period from December 1986 to October 1990, the EPA conducted five (5) removal actions
to address contamination and potential off-site releases from site.
On July 8, 1994, the Regional Administrator asked the State environmental agency to let bids received
from incineration contractors to expire without an award to allow the Congressional Office of Technology
Assessment (OTA) and General Accounting Office (GAO) to complete a study of incineration and
alternatives for the site. Incineration of contaminated soils at this abandoned creosote site had been
selected by the EPA under the Superfund law in 1990. Community outreach efforts and unusually strict
operating requirements did not quell objections by some local residents prompting requests from
Congress for OTA and GAO studies. As a result, the EPA withdrew the selected remedy.
During October 1996, the EPA collected contaminated soil samples from the site for soil stabilization
and bioremediation bench scale laboratory testing. The EPA used the results of these tests to determine
the suitability of several alternative remedies.
The Texas Natural Resource Conservation Commission (TNRCC)(presently the Texas Commission on
Environmental Quality (TCEQ)) awarded a contract in 1997 to improve fencing around the site and to
decontaminate and remove existing process equipment and structures. This work was completed in 1997.
On November 13, 1997, the EPA presented to the community the draft of an Amendment to the Record
of Decision proposing that the site be capped and that the ground water remedy be studied further. The
30-day comment period of this Record of Decision closed December 5, 1997. This ROD Amendment
was signed on March 13, 1998.
The State collected additional data on the extent of soil and water contamination and issued a detailed
report in March 1999.
3 EPA Publication Date: May 4, 2005
A field pilot study to evaluate the effectiveness of trenches in the collection and removal of Non-
Aqueous Phased Liquid (NAPL) was completed in November of 2000. The test indicated that trenches
were not the most effective method in collection of NAPLs.
Eight additional wells were installed in August of 2002 to confirm hydraulic conductivity through
pump tests, and to investigate the lateral extent of free product (NAPL) and ground water contamination.
The wells found additional NAPL in areas considered NAPL free.
In August 2003, geoprobe rigs were used to take subsurface cores and install temporary wells to
characterize the NAPL free product mass, NAPL residual and dissolved concentrations. In October 2003,
ground water sampling was conducted to delineate the lateral extent of dissolved contaminants. This
information will be used to tailor a cost effective remedy for this Site.
The subsurface soils and ground water analytical data acquired from the August, October and
November 2003 field work is being used in numerical models to develop an understanding of the
attenuative properties of the contaminated aquifer and to select the most effectiveness remedy.
EPA has completed bench-scale solidification and chemical oxidation treatability tests on soils and
ground water collected during the 2003 geoprobe investigation.
A Chemical Oxidation pilot test is being conducted to determine the applicabililty of Chemical
Oxidation in the source and dissolved plume areas. These treatabililty values are being used in a ground
water model simulation to determine if solidification and/or chemical oxidation and Monitored Natural
Attenuation will be cost effective remedies.
Nearest drinking water well is 2,400 feet east of the site.
Creosote contaminated soils, sludge, present a human health hazard
Other Environmental Risks:
Contamination of ground and surface water; drainage is to the southeast to Day's Creek

Signed: September 25, 1990
(Source and Shallow Ground Water)
Signed: September 30, 1993
(Deeper Ground Water)
Record of Decision Amendment
Signed: March 13, 1998
(Revised Source/Soils Remedy)
The 1990 ROD was to remediate contaminated Ground Water by:
Extracting, treating, and injecting the ground water into the shallow aquifer.
The 1990 ROD was to remediate contaminated Soils by:
Excavation of contaminated soils, on-site thermal destruction, and
burial on site (Soil remedy amended in February 1998)
EPA Publication Date: May 4, 20054TEXARKANA WOOD
Other Remedies Considered Reason Not Chosen
1. CappingNo reduction in volume or toxicity of contaminants.
2. Chemical Treating Only partially effective
3. Solidification Not permanent.
4. Biological TreatmentOnly partially effective.
5. Offsite Thermal DestructionToo costly; transportation risks.
6. "No Action"Not protective of human health and the environment.
Record of Decision Amendment
The soil remedy was amended to replace excavation of contaminated soils and on-site thermal destruction
of contaminated soils with containing contaminated soils beneath a soil cap on-site.

Citizens on site mailing list: 1400+ includes Texas and Arkansas residents.
- Site cleared of vegetation in February 1991 in response to local fire officials concerned about
potential air releases from grass fires on the site.
- Opposition to incineration remedy by community became very vocal in 1992.
- Arkansas Attorney General filed suit in December 1992 opposing remedy implementation; the
suit was dismissed.
- Congressman Chapman requested that incineration not be implemented until after the OTA and
GAO complete their study of incineration safety and the alternatives available for remediating the
- Incineration placed on hold pending review by Office of Technology Assessment.
- Incineration replaced with on-site capping remedy in Amended ROD on March 13,1998.
- General Accounting Office visited the community twice to interview citizens and assess impact
of site issues. The EPA studied alternative remedies for suitability.
- Community formed a Community Advisory Group (CAG)

Present Status and Issues
The EPA/TCEQ are presently working on a remedy which will address both soils and contaminated
ground water. The 1999 field sampling data on soils and groundwater, additional monitoring wells,
recent (2003) geoprobe investigations, ground water sampling and treatability tests are being used in
numerical modeling simulations to define the most appropriate remedy and bring this site to closure.
Following selection of a remedy, the existing ROD will be amended.
a perimeter fence prevents trespassing; vegetation is cleared on a regular basis.
Reduce the mobility of contaminants in soils and ground water. Prevent the public’s exposure to
