OverviewThe Biennial Reporting System is a national system that collects data on the generation, management, and minimization of hazardous waste. This system captures detailed data on the generation of hazardous waste from large quantity generators and data on waste management practices from treatment, storage, and disposal facilities. The biennial data provide a basis for trend analyses. Data about the previous year's hazardous waste activities is reported on even years by the facilities to EPA. EPA then provides reports on hazardous waste generation and management activity that accompany the data files. You may use a variety of data retrieval options in the Biennial Reporting System Query to search for other facilities that interest you. Information on related laws and regulations is also available.
