Chapter 173-303 WAC

Chapter 173-303 Washington Administrative Code (WAC), Dangerous Waste Regulations. These regulations set standards for safely managing state dangerous wastes. Chapter 173-303 WAC implements Chapter 70.105 RCW and Subtitle C of the federal Resource Conservation and Recovery Act (RCRA). Washington uses the term dangerous waste while the federal government uses the term hazardous waste. The term dangerous waste includes more waste than are in the federal hazardous waste definition because Washington’s rules are more protective.

The Department of Ecology (Ecology) plans to amend specific sections of chapter 173-303 WAC Dangerous Waste Regulations to incorporate new federal hazardous waste rules, including but not limited to:

  1. Management Standards for Hazardous Waste Pharmaceuticals and Amendments to the P075 Listing for Nicotine. 84 FR 5816; February 22, 2019
  2. Safe Management of Recalled Airbags. 83 FR 61552; November 30, 2018
  3. Hazardous Waste Management System: User Fees for the Electronic Hazardous Waste Manifest System and Amendments to Manifest Regulations. 83 FR 420; January 3, 2018

State-initiated amendments will also include:

  1. Corrections and clarifications to the Generator Improvements rule and other dangerous waste rules adopted January 28, 2019.
  2. Updating Biological Testing Methods for the Designation of Dangerous Waste, publication 80-12.
  3. Other clarifications and corrections as necessary.
