Chapter 173-350 WAC
Solid Waste Handling Standards


Available documents for this rule making are linked below.

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.

Response to Comments on First Preliminary Draft Rule

Release of Second Preliminary Draft Rule – December, 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).
