We strengthen regulations and streamline waste management

Biennial Reports Information

The 2019 Biennial Report Cycle has closed, but late submissions will be accepted.

If you haven’t done so already, please register at RCRAInfo.  

DTSC opted into the Federal RCRAInfo Biennial Report system for the 2019 cycle, and the Waste Reporting System (WRS) will remain available for prior-year information access only.


If, after reading the section on DEFINITION OF A RCRA LARGE QUANTITY GENERATOR, you still feel your site may be exempt from filing the Biennial Report, you may file an Exemption Request using the 2019 Biennial Hazardous Waste Report Exemption Request Form. Note: This is a request only. DTSC will contact you if your request is denied.

Send your exemption by email or fax:

Purpose of the Biennial Report

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.

Definition of a RCRA Large Quantity Generator

You are a RCRA Large Quantity Generator and required to file a 2019 Biennial Report if your site:

  1. Generated 1,000 kilograms (kg; 2,200 pounds [lbs.]) or more of non-acute RCRA hazardous waste (including quantities imported by importer site) in a single month; or
  2. Generated in a single month or accumulated at any time 1 kg (2.2 lbs.) or more of any RCRA acute hazardous wastes listed in 40 CFR sections 261.31 or 261.33 or
  3. Generated or accumulated at any time more than 100 kg (220 lbs.) of any residue or contaminated soil, waste, or other debris resulting from the cleanup of a spill, into or on any land or water, of any RCRA acute hazardous waste listed in 40 CFR sections 261.31 or 261.33(e) or
  4. Treated, stored, or disposed of RCRA hazardous wastes on-site during 2019. (TSDF)

Examples: did you do one of the following?

  • Became an LQG for one calendar month, even though you are a Small Quantity Generator (SQG), and generated excess amounts of RCRA or acute RCRA hazardous waste?
  • Generated residue-contaminated soil containing acute RCRA hazardous wastes that made you become an LQG for one calendar month (even if you are an SQG or a Very Small Quantity Generator [VSQG])?

Then you must complete the 2019 Biennial Report.

Did you change your generator status?

  • You’ll report your current hazardous waste generator status on the Site ID Form in Item 10.A.1 – Generator of Hazardous Waste – as of the date of submitting your 2019 Biennial Report. Your current status may be different from last year.

Are you a hazardous waste importer?

  • All Hazardous Waste imported from a foreign country in 2019 must be counted in determining your generator status.
  • This waste must be reported on the Waste Generation and Management Form (GM Form) or the Waste Received from Off-site Form (WR Form) in your 2019 Biennial Report.
