TRI - Toxic Chemical Release Inventory
The Toxic Chemical Release Inventory (TRI) contains information on the annual estimated releases of toxic chemicals to the environment, and amounts transferred to waste sites. TRI contains information on the releases (to air, water, land, or by underground injection) of over 300 chemicals and chemical categories from facilities in Standard Industrial Classification (SIC) codes 20 through 39, and with 10 or more full-time employees, and which exceed certain threshold quantities in their manufacture, processing or other uses. You may search TRI for specific sites, locations or compounds. You may use TRI to perform some statistical manipulations of the data.TRI can answer questions such as how much trichloroethylene was released to the air in Charleston County? How many sites in Berkeley County reported releases to the EPA? How much hazardous waste was received from other states at a hazardous waste landfill in South Carolina? What facility released the greatest amount of lead in the air in 1990? Section 313 of the Emergency Planning and Community Right-to-Know Act, also known as Title III of the Superfund Amendments and Reauthorization Act (SARA) of 1986, calls for the United States Environmental Protection Agency (EPA) to collect these data nationwide on an annual basis. Facilities subject to the reporting requirement must complete a Form R by July 1st for each chemical they released during the preceding calender year.
