Washington asbestos regulations.
Who licenses asbestos work in Washington, who takes the notification, and how long before the job you have to file. Plus how the federal rules layer on top.
State licensing & accreditation
Asbestos abatement work in Washington is licensed/accredited through the Washington State Dept. of Labor & Industries (L&I) under WAC Chapter 296-65 (Asbestos Removal & Encapsulation).
Credentials the state issues:
- Certified asbestos contractor
- Certified asbestos worker
- Certified asbestos supervisor
Washington State Dept. of Labor & Industries (L&I) — asbestos licensing.
Notification
Notifications go to the Washington L&I (worker-safety notification) AND local Clean Air agencies (NESHAP/air notification, e.g. Puget Sound Clean Air Agency) under WAC 296-65-020 (L&I); local clean air agency regulations (e.g. PSCAA Regulation III).
- Advance notice: L&I notification required for projects over 48 sq ft or 10 linear ft; local clean air agencies typically require a 10-day waiting period for friable projects above thresholds.
- Notification details / form.
How the federal rules layer in
No matter the state, federal OSHA 29 CFR 1926.1101 (asbestos in construction), EPA NESHAP (40 CFR 61, Subpart M), and AHERA worker accreditation still apply. A state program layers its own licensing and notification on top of — not instead of — these. Where Washington has no state license, the federal accreditation and NESHAP notification requirements are the floor.
Washington-specific notes
- Two-track system: L&I certifies contractors/workers/supervisors and takes a project notification; a separate notification/permit is also required from the local Clean Air agency.
- L&I notifications go to regional asbestos inspector inboxes by county.
- Local clean air agencies (PSCAA, SWCAA, etc.) administer the NESHAP-side program.

Items we could not fully verify against a primary source: Statewide advance-notice day count is not uniform; the 10-day waiting period applies under local clean air agency rules and varies by agency.
