Welcome to the Department of Toxic Substance Control’s Waste Reporting System (WRS). The Waste Reporting System (WRS) is designed for hazardous waste generators and facilities to enter and report their hazardous waste activities for the Annual Facility Report or Biennial Hazardous Waste Report. This system offers a quick and convenient way to file your Hazardous Waste Report.

Annual Facility Report

A Treatment, Storage, or Disposal Facility (TSDF) is required to file the Annual Facility Report (AFR) for activities conducted in the prior year, pursuant to the California Code of Regulations, Title 22, Division 4.5:

The Department of Toxic Substances Control holds facilities that handle hazardous wastes to high standards of operation. TSDFs are required to report all RCRA and State hazardous waste activities to maintain regulatory compliance in accordance with the AFR. Failure to comply with state regulations regarding Annual Facility Reports may result in fines and penalties.

DTSC collects and maintains information via the Annual Facility Report to analyze hazardous waste management activities in the state. DTSC uses this data to identify trends in hazardous waste management and to monitor hazardous waste facilities in California.

Biennial Report

Federal regulations require large quantity generators to submit a report every two years regarding the nature, quantities and disposition of hazardous waste generated at their facility. The U.S. Environmental Protection Agency refers to this as the National Biennial RCRA Hazardous Waste Report or Biennial Report.

The Biennial Report must be submitted to DTSC by March 1 of every even-numbered year (for example, a report due by March 1, 2018, would report activities from calendar year 2017). The report includes information such as:

  • Facility’s EPA ID Number,
  • Facility’s name and address,
  • Quantity and nature of hazardous waste generated, and
  • Whether the hazardous waste was sent for recycling, treatment, storage, or disposal.
