Plan holders shall prepare a plan that demonstrates capability, to the maximum extent practicable, of promptly and properly removing oil and minimizing environmental damage from a variety of spill sizes, up to and including worst case spills. Ecology will evaluate plans based on these conditions:

(1) Only ecology approved PRC resources, plan holder owned resources and resources guaranteed through contract, written mutual aid agreements, or letters of intent shall be counted when calculating the planning standards. In the case of nondedicated storage devices, these will be derated by fifty percent of maximum storage volume (counted at a one to two ratio) and acquisition of these resources will be tested in unannounced drills.

(2) Ecology will count equipment if it is appropriate for the operating environment within the geographic area defined in the plan. Ecology will use criteria from sources such as the ASTM International documents, World Catalogue, manufacturer's recommendations, the Worldwide Response Resource List (WRRL), the federal Oil Spill Removal Organization guidelines, the Field Operations Guide resource typing guidelines and drills and spills to make approval and verification determinations on operating environments.

(3) Ecology will count boom if it is appropriate to the operating environment and support equipment is identified. Support equipment for boom means transportation devices, cranes, anchors, boom tackle, connectors, work boats and operators.

(4) Ecology will only count dedicated response resources towards the two hour standards.
