RCRA requires EPA to develop a program for hazardous waste generators to report the nature, quantities, and disposition of hazardous waste generated at least once every two years. RCRA also requires treatment, storage and disposal facilities (TSDFs) to submit a report on the wastes that they receive from off-site. The biennial Hazardous Waste Report (also known as the “Biennial Report”) was implemented in 1985 to comply with these requirements. The Biennial Report form (8700-13A/B) must be submitted to the authorized state agency or the EPA Regional Office by March 1st of every even-numbered year. The form includes information such as the facility's EPA identification (ID) number, the name and address of the facility, the quantity of hazardous waste sent to each TSDF in the U.S. and the manner in which the waste was treated during the previous year.
