(1) Drill credits for actual spills: Rail plan holders may request drill credit for a response to an actual spill, provided that ecology has an opportunity to participate during the spill and evaluate the spill response.

If credit for a spill is requested more than once per triennial cycle, it is up to the discretion of ecology if additional credit. The requested additional spill credit may be granted if significant lessons learned from the spill or key response components were successfully demonstrated.

The request shall include documentation supporting the components of WAC 173-186-520.
