The Department of Ecology is proposing to amend Chapter 173-303 WAC, Dangerous Waste Regulations. These regulations set standards for the safe management of dangerous wastes. Ecology plans to amend specific sections of the dangerous waste regulations to incorporate new federal hazardous waste rules. We propose to restructure the regulations for easier use and improved compliance. The proposed changes in the dangerous waste regulations will affect most dangerous waste generators. These changes may affect how generators manage their dangerous waste, adding regulations for solvent-contaminated wipes, recycling of dangerous waste, electronic manifests and dangerous waste import and export. Other amendments include several minor state-initiated technical changes, editorial corrections, and clarifications.
EPA rules include:
State-initiated changes include, but are not limited to:
- Conditional Exclusions for Solvent-Contaminated Wipes
- Definition of Solid Waste: Revisions to Solid Waste Variances and to the Definition of Legitimacy
- Revisions to the Export Provisions of the Cathode Ray Tube (CRT) Rule
- Hazardous Waste Generator Improvements Rule
- Hazardous Waste Export-Import Revisions
- Hazardous Waste Electronic Manifest Rule
- Changes to the PCB waste exclusion reducing duplicative regulation of state-only PCB wastes also regulated under the Toxic Substances Control Act 40 CFR Part 760.
- Above-ground signage requirements for underground dangerous waste tanks.
See the proposed language for more details on all changes.
