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 focus on clarifying how we implement the Hazardous Waste Fee Regulation, including the Hazardous Waste Planning Fee (planning fee). We will also make updates throughout the chapter to reflect new statutory references and improve clarity.

The planning fee does not clarify how we calculate the fee for an individual waste stream that designates as both dangerous waste (DW) and extremely hazardous waste (EHW). This rulemaking will clarify how we calculate the planning fee for this type of waste stream. It will also better explain how we implement chapter 173-305 WAC by making the current language concise and easier to understand.

Ecology previously filed a CR-101 to amend this chapter on September 14, 2022 (WSR 22-19-037). We withdrew that CR-101 on October 13, 2023 (WSR 23-21-072). This new CR-101 filing will improve clarity, consistency, and plain language throughout the chapter rather than in one section.

Public input & involvement

Public input was gathered during the initial rule development (after the original CR 101 was filed on Sept. 14, 2022) and will continue until Fall 2024.

We held two informational webinars in May 2023 as an opportunity to provide informal feedback to us.

During these webinars, we provided an overview of:

  • The planning fee—what it is, who pays, why, and how it’s calculated. 
  • Purpose and goals of the rulemaking.
  • Rulemaking timeline and opportunities for public participation.
