A public-comment period is open for proposed updates to Chapter 173-50 WAC: Accreditation of Environmental Laboratories.
We propose to amend the Laboratory Accreditation rule to update the accreditation process to keep up with inflation, provide more technical assistance, and maintain the laboratory accreditation program.
The WAC 173-50: Accreditation of Environmental Laboratories rulemaking page has more information about proposed rule changes, documents to review, and ways to comment.
