Risk Management Plans (RMP)

Federal law requires facilities that use large amounts of extremely hazardous substances to file Risk Management Plans with the EPA. This data is intended to save lives, protect property and prevent pollution. You can identify facilities in your area by using the RMP search tool.

Biennial Reporting System (BRS)

The Biennial Reporting System (BRS) is one of the Environmental Protection Agency’s primary tools for tracking the generation, shipment and receipt of hazardous waste. It contains information from Hazardous Waste Reports that must be filed every two years under the Resource Conservation and Recovery Act, which is the federal law that regulates the generation, treatment, storage, disposal or recycling of solid and hazardous waste.


This database includes information from companies that generate, transport, treat, store and dispose of hazardous waste, which are required to report certain activities to state-level regulators. These regulators pass on the information to the EPA. Data includes permit status, compliance and violation information, and cleanup activities. The information is mandated by the Resource Conservation and Recovery Act (RCRA), as amended in 1984.

Toxic Release Inventory (TRI)

This inventory is a database of information about releases and transfers of toxic chemicals from facilities in certain industrial sectors, including manufacturing, waste handling, mining and electricity generation. Facilities also must report the total amount of toxic chemicals in waste they produce.
