History
The Alcoa (Point Comfort)/Lavaca Bay site is located in Calhoun County, Texas, near the City of Point Comfort. The area includes the approximately 3,500-acre Alcoa Point Comfort Operations (PCO) Plant, Dredge Island, portions of Lavaca Bay, Cox Bay, Cox Creek, Cox Cove, Cox Lake and western Matagorda Bay.
The PCO Plant was established as an aluminum smelter in 1948. Smelting operations were curtailed in 1980. Bauxite refining, which utilizes bauxite ore to produce alumina, began in 1958. Past operations that have been dismantled and removed include the smelter, a cryolite plant, a chlor-alkali plant, and the Witco coal tar processing plant.
The facility’s alumina refinery, the last remaining operation, was curtailed in June of 2016, closed in December of 2019, and is currently undergoing demolition.
Alcoa is committed to returning the site to productive reuse for the benefit of the community, and responsibly manages the demolition, remediation, and ongoing monitoring activity at the site. Alcoa works closely with all federal, state and local authorities engaged in site restoration activities including the U.S. EPA, U.S. Army Corps of Engineers, Texas Commission on Environmental Quality, Texas State Department of Health Services, and Calhoun Port Authority.
