The Maintech International site (the site) is located at 8300 Old Ferry Road in Port Arthur. The 10-acre site is approximately 0.25 mile northwest of the point where the Neches River empties into Sabine Lake. Prior to 1975, the property was used for wastewater disposal from a barge-cleaning facility. A bermed area was used as a pit for collected ballast and cleaning water from oil barges. In 1975, facilities were built to provide support for chemical cleaning and equipment hydroblasting services to area petrochemical plants and refineries. Included at the site were three wastewater collection ponds with a total capacity of about 2 million gallons. Activities at the site were halted in 1986, and all facilities have been out of service since then.
