Section 112(r) of the Clean Air Act
Accidental Release Prevention Program
At the South Carolina Department of Health and Environmental Control, the Bureau of Air Quality (BAQ) currently implements the 112(r) regulation for all affected sources. BAQ conducts site inspections and audits to determine compliance with the risk management program requirements. The risk management program is funded by air permit fees and Federal grants.
Facilities that have more than the threshold quantity (TQ) of a 112(r) listed "regulated substance" in a single process must develop and implement a risk management program, by June 21, 1999, as specified by the rule. In terms of the regulation, "process" means manufacturing, storing, distributing, handling, or using a regulated substance in any way. Facilities subject to the rule must conduct a hazard assessment, compile a 5-year accident history, develop an accident prevention program, develop an emergency response program, and submit risk management information to U.S. Environmental Protection Agency (EPA) by June 21, 1999.
Over 200 sources in South Carolina submitted risk management information to EPA by the June 21, 1999 compliance deadline. Some of those sources include: water and wastewater treatment plants, chemical plants, pulp and paper mills, ammonia refrigeration facilities and warehouses, and agricultural retail facilities. Chlorine and ammonia were the two listed substances most facilities reported.
List of Regulated Substances
The original 112(r) List of Regulated Substances was published by the EPA on January 31, 1994 and it has been revised several times. The list consists of 77 toxic and 63 flammable chemical substances that if accidentally released could cause death, injury, or severe adverse effects to human health and the environment. The threshold quantities range from 500 to 20,000 pounds for each process.
