Dorchester Refining Company

No further Superfund environmental response actions are required on this oil refinery in Mount Pleasant, Titus County. This site was referred to the Voluntary Cleanup Program.

REFERRED TO Voluntary Cleanup Program (VCP ID 2010)

Site Background

The Dorchester Refining Company site is located on the west border of the city of Mount Pleasant in the 1700 block of West First Street. The site is bordered by the St. Louis Southwestern Railroad on the south, suburban areas to the west and north, Conoco to the northeast and a residential area to the southeast. Dorchester Refining was an active facility under several owners from 1936 to 1984, producing gasoline, diesel and asphalt products. In late 1984, Dorchester Refining sold off the storage tanks and bulk terminal. The property and refining equipment was purchased by Trey Corporation. Trey Corporation completed a Chapter 7 liquidation in November 2000. Numerous notices of violations were filed against the site for releases of hazardous substances into Tankersley Creek, which flows into Big Cypress Creek, a documented wetland and fishery area. From 1995 through 2003, efforts to get the site owners to take part in the cleanup of the contamination brought no results. The site was referred to Superfund for investigation and cleanup.
