Had the EPA and USCG FRP inspectors been required to fully assess the functioning of the containment dike, dike drain valves, and the full scope of CAPECO’s emergency discharge plan, CAPECO might not have received a satisfactory inspection and would have had to evaluate its inadequate dike drainage system, which led to the spread of the gasoline vapor cloud. See Section 6.9.1 for discussion on dike drain valves.
