United States Environmental Protection Agency (EPA): Toxics Release Inventory (TRI) Program

Public interest and environmental organizations around the country accelerated demands for information on toxic chemicals being released "beyond the fence line" -- outside of the facility. Against this background, the Emergency Planning and Community Right-to-Know Act (EPCRA) was enacted in 1986.  EPCRA's primary purpose is to inform communities and citizens of chemical hazards in their areas. EPCRA Section 313 requires EPA and the States to collect data annually on releases and transfers of certain toxic chemicals from industrial facilities and make the data available to the public in the Toxics Release Inventory (TRI).  Includes information on toxic substances, where and by whom they are released.  Information available state by state.
