The State Department of Health is currently in the process of revision WAC 246-272A which outlines Rules overseeing all Onsite Sewage Systems (OSS) in the State of Washington. COOMWA has participated in the process as a “Stakeholder”, attending meetings to discuss changes.
The Stakeholder meetings were run under the “Democratic”, majority rules voting system. Many of our concerns were voted down!
The 169-page document, showing recommended changes, can be found at
The final approval of the Revised Rule will be made by the State Board of Health, a body appointed by the Governor. Your comments or concerns can be sent directly to them at: WSBoH@sboh.wa.gov.
Letters from COOMWA to the Board will be posted on this website.
