The Department of Ecology adopted amendments to Chapter 173-303 WAC Dangerous Waste Regulations on January 28, 2019. The amendments become effective 90 days after adoption on April 28, 2019. These regulations set standards for the safe management of dangerous wastes. Ecology amended specific sections of the dangerous waste regulations to incorporate new federal hazardous waste rules, including but not limited to:
1) Conditional Exclusions for Solvent-Contaminated Wipes
2) Revisions to the Definition of Solid Waste
3) Revisions to the Export Provisions of the Cathode Ray Tube (CRT) Rule.
4) Hazardous Waste Generator Improvements Rule
5) Hazardous Waste Export-Import Revisions
6) Hazardous Waste Electronic Manifest Rule
Amendments also include several state-initiated technical and editorial corrections and clarifications. Substantive changes include, but are not limited to:
- Changes to the PCB waste exclusion to reduce duplicative regulation of state-only PCB wastes also regulated under the Toxic Substance Control Act 40 CFR Part 760.
- Above-ground signage requirements for underground dangerous waste tanks to increase safety awareness.
