Ecology is starting a rulemaking to amend Chapter 173-180 WAC, Facility Oil Handling Standards and Chapter 173-184 WAC, Vessel Oil Transfer Advance Notice and Containment Requirements. Chapter 173-180 WAC establishes oil spill prevention and oil transfer requirements for regulated oil handling facilities.
