SUPPLEMENTARY INFORMATION:

The Site consists of approximately 17 acres located 4.5 miles northeast of the city of Port Arthur in Jefferson County along Ferry (or Old Yacht Club) Road on Pleasure Islet, approximately one-half mile southwest of the confluence of the Neches River and the Sabine-Neches Ship Channel. The Site is bordered by the State Marine Superfund site to the south, Sabine Lake to the east, Old Yacht Club Road to the West, and vacant property to the north.

The Site was originally used as a municipal landfill for the city of Port Arthur, which operated the landfill from 1956 until the mid-1980s. In 1982, the city of Port Arthur sold the property and it was subsequently used as a marine barge cleaning operation (Palmer Barge Marine) from 1982 until 1997. Operations performed at the site included cleaning, degassing, maintenance and inspection of barges and marine equipment. A flare was located on-site to burn excess gasses and liquids produced during the facility operations, in addition to multiple above-ground storage tanks. In July 1997, Palmer Barge Line was purchased and operations on the property ceased. Currently the site is owned by a private individual who is redeveloping it as an industrial property.

In 1996, the TCEQ (then known as the Texas Natural Resource Conservation Commission, or TNRCC) conducted a multi-media inspection of the Site which identified large areas of contamination on Site soils. These findings triggered further investigation by both the U.S. Environmental Protection Agency (EPA) and TCEQ. In 1996, an expanded site inspection (ESI) was performed for the purpose of evaluating the nature and extent of on-site and off-site contamination and evaluating the environmental fate of the contaminants. This evaluation indicated the presence of both organic and inorganic contaminants in Site soils and in the shallow near-shore sediments of Sabine Lake. Semi-volatile contaminants of concern identified at the Site include acenaphthylene, anthracene, benzo(a)pyrene, chrysene and fluoranthene. There were also numerous pesticides and poly-chlorinated bi-phenyls detected in the Site soil samples. Elevated levels of inorganic contaminants included chromium, copper, lead, and zinc.

The Site was placed on the National Priorities List (Superfund) on July 27, 2000 and the EPA authorized an emergency removal action for reduction of on-site contamination in August 2000. Removal activities included removal of wastes, wastewater treatment, and sludge stabilization. A Remedial Investigation (RI) was performed at the Site pursuant to an Administrative Order on Consent signed by the EPA and the Settling Parties in 2002, and based on information developed in the RI, a Record of Decision (ROD) for the Site was signed on September 30, 2005. The ROD requires the excavation of approximately 1,204 cubic yards of soil which exceeded risk-based levels, backfilling of excavated areas with clean soil, and off-site disposal of excavated soils at a permitted disposal facility. Existing above-ground storage tanks will be demolished and removed. As planned, and when implemented, the remedy selected to address the contamination at the Site is expected to protect natural resources in the vicinity of the Site from further or future injury.

NOAA, DOI, TPWD, GLO and TCEQ are designated Natural Resource Trustees under Section 107(f) of CERCLA, Section 311 of the Federal ( printed page 31056) Water Pollution and Control Act (FWPCA), 33 U.S.C. Section 1321, and other applicable federal or state laws, including Subpart G of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP), 40 CFR 300.600-300.615. As trustees, these agencies are authorized to act on behalf of the public under these authorities to protect and restore natural resources injured or lost as a result of discharges or releases of hazardous substances.

Paralleling the remedial investigations at the Site, the Trustees worked cooperatively with E.I. du Pont de Nemours and Company, Texaco Inc., Ashland Inc, and Kirby Inland Marine, L.P., to evaluate natural resource injuries and ecological service losses resulting from releases of hazardous substances to areas at or adjacent to the Site. The Trustees' evaluation focused on natural resource injuries or service losses of an ecological nature caused by hazardous substances at the Site based on known contamination and anticipated remedial actions. As a result of this assessment, the Trustees determined that hazardous substances (including semi-volatile organic compounds, poly-cyclic aromatic hydrocarbons, poly-chlorinated bi-phenyls , pesticides, and metals) were available in the sediments and injury to ecological habitat of approximately 7.55 acres had occurred.

The Draft DARP/EA identifies the information and methods used to define the natural resource injuries and losses of an ecological nature, including the scale of restoration actions, and identifies the restoration actions which are preferred to restore, replace or acquire resources or services equivalent to those lost.
