How is MRW regulated in Washington?

Moderate Risk Waste is regulated by WAC 173-350-360 (adopted statewide in February 2003) under the authority of RCW 70.105 and RCW 70.95. Local Health Jurisdictions are responsible for implementing and enforcing this regulation, and counties may adopt local ordinances and local hazardous waste management plans that have additional handling requirements for MRW. Regional Ecology staff can help answer technical questions about these regulations.
