Except as provided in subdivision (b), the responsible party, potentially responsible parties, their agents and employees, the operators of all vessels docked at a marine facility that is the source of a discharge, and all state and local agencies shall carry out spill response consistent with the
California oil spill contingency plan or other applicable federal, state, or local spill response plans, and owners and operators shall carry out spill response consistent with their applicable response contingency plans, unless directed otherwise by the administrator, the United States Coast Guard, or the United States Environmental Protection Agency.

If a responsible party or potentially responsible party reasonably, and in good faith, believes that the directions or orders given by the administrator pursuant to subdivision (a) will substantially endanger the public safety or the environment, the party may refuse to act in compliance with the orders or directions of the administrator. The responsible party or potentially responsible party shall state, at the time of the refusal, the reasons why the party refuses to follow the orders
