Environmental Control Programs In An Alumina Plant

Kaiser Aluminum & Chemical Corporation's (KACC) entrance into the alumina market began in 1946 with the purchase of a small plant in Baton Rouge. Louisiana. Since that time KACC has been involved with the design, construct; on, and operation of many alumina plants around the world. One of these plants is located in Gramercy, Louisiana. The Gramercy Works is a multiplant installation consisting of an alumina plant, a caustic-chlorine plant, a petroleum coke calciner and a fluorochemicals plant. Each of these plants require their own specific environmental control programs to abate pollution. Kaiser has made significant progress through the years on their own initiative in pollution control. But many new challenges have been and continue to be created with the enactment of environmental laws. The 1970 Clean Air Act Amendments, the resurrection of the old "Refuse Act" in 1970 and finally the 1972 Federal Water Pollution Control Act Amendments prompted the formulation of our current philosophy towards the abatement of pollution. Since the formulation of these complicated pieces of legislation, others equally complicated, have come to being. The Federal Insecticide, Fungicide and Rodenticide Act as amended by the Federal Environmental Pesticide Control Act of October, 1972, the Toxic Substances Control Act of 1976, the Solid Waste Disposal and Resource Recovery Act of 1976 and the Safe Drinking Water Act sighed in December of 1974 have all contributed to the challenge for an alumina plant to meet regulatory constraints. However, this paper will only discuss the alumina plant?s environmental programs designed to meet compliance with air and water pollution legislation. At the Gramercy Alumina Plant, over $25 million has been spent for pollution control since 1969. The Gramercy Plant is a prime example of KACC's commitment to meeting the environmental challenge.
