(a)

(1) The board shall determine whether it is necessary to apply to the federal government for the state to prohibit the release of sewage or sewage sludge from large passenger vessels, sewage from oceangoing ships with sufficient holding tank capacity, and sewage sludge from oceangoing ships, into the marine waters of the state or to prohibit the release of sewage sludge from large passenger vessels and oceangoing ships into marine sanctuaries, as described in

Section 72420. If the board determines that application is necessary for either sewage or sewage sludge, or both, it shall apply to the appropriate federal agencies, as determined by the board, to authorize the state to prohibit the release of sewage or sewage sludge, or both, as necessary, from large passenger vessels, sewage from oceangoing ships with sufficient holding tank capacity, and sewage sludge from oceangoing ships, into the marine waters of the state and, if necessary, to authorize the state to prohibit the release of sewage sludge from large passenger vessels and oceangoing ships into marine sanctuaries.

(2) It is not the Legislature’s intent to establish for the marine waters of the state a no discharge zone for sewage from all vessels, but only for a class of vessels. (

b) The board shall request the appropriate federal agencies, as determined by the board, to prohibit the release of sewage sludge and oily bilgewater, except under the circumstances specified in

Section 72441, by large passenger vessels and oceangoing ships, in all of the waters that are in the Channel Islands National Marine Sanctuary, Cordell Bank National Marine Sanctuary, Gulf of the Farallones National Marine Sanctuary, and Monterey Bay National Marine Sanctuary, that are not in the state waters.
