Hazardous Waste Icon


Large quantity generator of RCRA wastes must complete a biennial report every two years. Reports for the previous (odd-numbered) year are due on March 1 of even-numbered years. “DTSC and U.S. EPA have a common mission to protect human health and the environment, which they carry out by enforcing strict management standards for hazardous wastes, and gathering information about the generation, transportation and final disposition of hazardous waste in the state.

The federal and state hazardous waste regulations require certain federally-regulated (RCRA) hazardous waste generators, as well as, facilities that treat, store or dispose of RCRA hazardous waste, to report their hazardous waste activities biennially in odd-numbered calendar years. The information collected will:

  • Provide the U.S. EPA and California with a view of current hazardous waste generation and waste management in the United States;
  • Show trends and changes in waste management and quantity when compared to past years’ reports;
  • Be summarized and provided to the public, primarily through publication of the National Biennial RCRA Hazardous Waste Report” (California Department of Toxic Substance Control’).
