Chapter 173-186 WAC

Ecology plans to amend Chapter 173-186 WAC, Oil Spill Contingency Plan – Railroad. This chapter requires railroads carrying oil as cargo to plan for oil spills to include how to make notifications, have the appropriate equipment and trained personnel to respond to spills that may occur. This rulemaking will:

  • Establish three tiers for railroad contingency planning and streamline requirements according to RCW 90.56.210.
  • Establish requirements for citing Spill Management Teams including entities providing wildlife rehabilitation and recovery services.
  • Enhance requirements for readiness for spills of oils that may weather and sink.
  • Update drill requirements to reflect legislative direction.
  • Make other edits to address inconsistent or unclear direction in the rule.
