Chapter 173-305 WAC

The Washington State Department of Ecology (Ecology) plans to amend chapter 173-305 WAC Hazardous Waste Fee Regulation. This rulemaking will specifically focus on amending section 220, the Hazardous Waste Planning Fee (planning fee). We will also update citations in this chapter to match new statutory references per the requirements of Substitute House Bill 2246, Chapter 20, Laws of 2020.

The planning fee in WAC 173-305-220 doesn’t state which risk factor to apply to an individual waste stream that designates as both dangerous waste (DW) and extremely hazardous waste (EHW). This rulemaking will clarify how Ecology calculates the planning fee by adding language that directs Ecology to apply a risk factor of 1 to a waste stream that designates as both DW and EHW.
