Uncrewed Aerial Systems
WAC 173-182 & WAC 173-186
Drones have become a standard tool in oil spill response but aren't well reflected in current rules. The BAP workgroup recommended writing rules around mission objectives — like mapping a spill's extent or assessing shoreline damage — rather than specific equipment, so the rules don't become outdated as technology evolves.
Rulemaking Progress
BAP UAS workgroup recommendations discussed at March 2026 workshop. General consensus on minor updates — focus on capabilities/outcomes rather than specific equipment. Harmonize facility and vessel aerial surveillance standards. Draft rule language expected April/May 2026.
Key Issues
- UAS as optional response tool in low visibility
- Alignment between facility and vessel planning standards
- Outcome-based vs. equipment-specific rule language
- FAA Part 107 regulatory framework
- Real-time thermal/optical imagery capabilities

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.
