Abstract

The Clean Water Act (CWA) states that regulations shall be issued "which require an owner or operator of a tank vessel or facility ... to prepare and submit ... a plan for responding, to the maximum extent practicable, to a worst case discharge, and to a substantial threat of such a discharge, of ... a hazardous substance." The Environmental Protection Agency is considering developing a regulatory action to require planning for worst case discharges of CWA hazardous substances under section 311(j)(5)(A).
