Shoreline Cleanup Assessment Technique
WAC 173-182 & WAC 173-186
When oil reaches shore, systematic survey teams assess the damage and direct cleanup efforts. The BAP workgroup found that current rules barely mention this process and recommended building it into a broader Shoreline Response Program with defined roles, earlier mobilization timelines, and pre-mapped shoreline segments so responders aren't starting from scratch during an incident.
Rulemaking Progress
BAP SCAT workgroup recommendations discussed at March 2026 workshop. Key themes: whether SCAT requirements belong in WAC vs. area plan, co-leadership model, mobilization timelines. Draft rule language expected April/May 2026.
Key Issues
- Integration of SCAT into contingency planning standards
- Shoreline Response Program (SRP) framework
- SCAT mobilization timeframes
- Roles and responsibilities (Coordinator, Data Manager, Field Team Lead)
- SCAT-OPS Liaison position for ICS communication

BAP Workshop: Drills
Workshop14:00 - 16:00 PT • Virtual (Zoom)
BAP-topic workshop focused on drill requirements for non-floating oil response and Southern Resident Killer Whale deterrence. Reviewed 2023 NW Area Committee Task Force report and 2025 BAP workgroup recommendations, analyzed current rule language gaps, and opened discussion on strengthening drill requirements.
BAP Workshop: SCAT & UAS
Workshop11:00 - 12:30 PT • Virtual (Zoom)
BAP-topic workshop on Shoreline Cleanup Assessment Technique (SCAT) and Uncrewed Aerial Systems (UAS). Discussed incorporating SCAT into WAC shoreline cleanup language, the relationship between WAC and area plan requirements, and whether aerial surveillance language should be updated for UAS. Ecology indicated draft rule language is expected in April or May 2026.
Draft Rule Language Expected for Informal Review
MilestoneEcology indicated during March 2026 workshops that draft rule language will be available for informal stakeholder review in April or May 2026. A second draft is expected in summer 2026. This is an informal review period distinct from the formal public comment period later in the process. WSMC members should plan to review and provide feedback during this window.
