Chapter 173-350 WAC
Experience implementing the rule and input from stakeholders identified many areas in need of improvement. Issues identified as priorities included updating definitions, clarifying criteria for inert waste classification and when earthen material/soil is a solid waste, as well as streamlining record keeping and reporting requirements. In the pre-proposal statement of inquiry for this rulemaking, Ecology announced it would also address other issues that might result in substantive changes, as well as clarifications and corrections to language in the chapter not expected to change the overall effect of the rule. This rulemaking:
- Standardizes language and organization to improve usability and consistency across the rule.
- Improves user ability to identify solid wastes apart from commodities, and supports material recovery and recycling activities while protecting public health and the environment.
- Helps users more easily distinguish inert wastes from other materials requiring a higher standard of management.
- Clarifies applicability of the rule, operational requirements, and timeframes for managing solid wastes in piles.
- Distinguishes between clean and contaminated soils and dredged material, and clarifies management requirements.
- Makes other substantive as well as clarifying revisions to the rule.

Work Groups/Advisory Committee
The work of our advisory committees in helping to prepare the preliminary draft rule has concluded. Ecology is very grateful for the time and effort put in by the many stakeholder representatives who participated. Names of many advisors and meeting documentation can be found below here.
To see more details about the work conducted by the work groups and advisory committee please visit this page.
First Preliminary Draft - comments were due June 2016
Ecology evaluated all comments received on the first preliminary draft of the rule (June 2016). Our response is linked below. Not all comments resulted in changes to the rule. In our response, we focused on comments that evolved as a significant concern for stakeholders, where clarification of the agency’s intent was needed, and where significant changes to the rule would affect the way it might be interpreted or implemented. Ecology is preparing a response to comments received on the second draft of the rule (December 2016). The response will be posted when available, and stakeholders will be notified.
Second Preliminary Draft December 2016 - comments were due February 2017
To make chapter 173-350 WAC more manageable for review, it was broken into several different documents. This should make finding a particular section easier. Each document is available as a pdf or as a Microsoft Word document. If using the Word version, you will be able to use the “review” settings to either see all the tracked changes, or to view the document in a clean (“no markup”) version. If you use the pdf version, you will see all the changes as either underline (additions) or strike-out (deletions).
The sections were broken up into documents as follows:
- Part One: 010 Purpose, -020 Applicability, -021 Determination of solid waste, -025 Owner responsibilities for solid waste, -030 Effective dates, -040 Performance standards, -100 Definitions, and -200 Beneficial use permit exemptions. (PDF Format)
- Part Two: 210 Recycling and material recovery facilities, -220 Composting facilities, -225 Other organic material handling activities, -230 Land application, -240 Energy recovery and incineration facilities, -250 Anaerobic digesters, and -300 On-site storage, collection and transportation standards. (PDF Format)
- Part Three: 310 Transfer stations and drop box facilities, -320 Piles used for storage or treatment, -330 Surface impoundments and tanks, -350 Waste tire storage, -355 Waste tire transportation, and -360 Moderate risk waste handling. (PDF Format)
- Part Four: 400 Limited purpose landfills, -410 Inert waste landfills, and -490 Other methods of solid waste handling. (PDF Format)
- Part Five: 500 Groundwater monitoring, -600 Financial assurance requirements, -700 Permits and local ordinances, -710 Permit application and issuance, -715 General permit application requirements, -900 Remedial action, and -995 Soil and sediment use criteria.(PDF Format)
Ecology evaluated all comments received on the second preliminary draft of the rule (December 2016). Our response (November 2017) is linked below.
