(1) Plan holders may request drill credit for a response to an actual spill, provided that ecology has an opportunity to participate and evaluate the spill response. Credit from spills shall not entirely alleviate the plan holder's responsibility to drill.

(a) Credit for a spill may be used to replace the requirement to conduct a drill once per triennial cycle.

(b) If credit for a spill is requested more than once per triennial cycle, it is at the discretion of ecology if additional drill credit will be granted. Additional credit may be granted if there were lessons learned from the spill or if key response components were successfully demonstrated.

(2) To obtain credit, a written request to ecology shall be made within sixty days of completion of the cleanup operations.

(a) The request shall include documentation supporting the components of WAC 173-182-720.

(b) Plan holders shall have up to ninety days to submit a lessons learned summary supporting the request for drill credit.

(3) Plan holders may request drill credit for out-of-state tabletop drills if:

(a) Ecology has been invited to attend the drill;

(b) Ecology has an opportunity to participate in the planning process for the drill. There shall be a meeting to discuss the scope and scale of the exercise, the drill objectives and the types of criteria for which Washington credit may be applicable;

(c) Documentation of the drill and self certification documentation shall be provided to ecology within thirty days of the drill;

(d) The plan holder has one response plan for a number of facilities or a fleet of vessels; and

(e) Plan holders seeking credit for a scheduled out-of-state drill shall notify ecology in writing ninety days in advance, to provide ecology an opportunity to participate.
