(b) After one or more public hearings, and prior to January 1, 1979, the commission shall designate those specific locations within the Suisun Marsh, as defined in Section 29101 of the Public Resources Code, or the area of jurisdiction of the commission, where the location of a facility, as defined in Section 25110 of the Public Resources Code, would be inconsistent with this title or Division 19 (commencing with Section 29000) of the Public Resources Code. The following locations, however, shall not be so designated: (1) any property of a utility that is used for such a facility or will be used for the reasonable expansion thereof; (2) any site for which a notice of intention to file an application for certification has been filed pursuant to Section 25502 of the Public Resources Code prior to January 1, 1978, and is subsequently approved pursuant to Section 22516 of the Public Resources Code; and (3) the area east of Collinsville Road that is designated for water-related industrial use on the Suisun Marsh Protection Plan Map. Each designation made pursuant to this section shall include a description of the boundaries of those locations, the provisions of this title or Division 19 (commencing with Section 29000) of the Public Resources Code with which they would be inconsistent, and detailed findings concerning the significant adverse impacts that would result from development of a facility in the designated area. The commission shall consider the conclusions, if any, reached by the State Energy Resources Conservation and Development Commission in its most recently promulgated comprehensive report issued pursuant to Section 25309 of the Public Resources Code. The commission also shall request the assistance of the State Energy Resources Conservation and Development Commission in carrying out the requirements of this section. The commission shall transmit a copy of its report prepared pursuant to this subdivision to the State Energy Resources Conservation and Development Commission.
(c) The commission shall revise and update the designations specified in subdivision (b) not less than once every five years. The provisions of subdivision (b) shall not apply to any sites and related facilities specified in any notice of intention to file an application for certification filed pursuant to Section 25502 of the Public Resources Code prior to designation of additional locations made by the commission pursuant to this subdivision.
(d) Whenever the State Energy Resources Conservation and Development Commission exercises its siting authority and undertakes proceedings pursuant to the provisions of Chapter 6 (commencing with Section 25500) of Division 15 of the Public Resources Code with respect to any thermal powerplant or transmission line to be located, in whole or in part, within the Suisun Marsh or the area of jurisdiction of the commission, the commission shall participate in those proceedings and shall receive from the State Energy Resources Conservation and Development Commission any notice of intention to file an application for certification of a site and related facilities within the Suisun Marsh or the area of jurisdiction of the commission. The commission shall analyze each notice of intention and, prior to commencement of the hearings conducted pursuant to Section 25513 of the Public Resources Code, shall forward to the State Energy Resources Conservation and Development Commission a written report on the suitability of the proposed site and related facilities specified in that notice. The commission’s report shall contain a consideration of, and findings regarding, the following:
1. (1) If it is to be located within the Suisun Marsh, the consistency of the proposed site and related facilities, with the provisions of this title and Division 19 (commencing with Section 29000) of the Public Resources Code, the policies of the Suisun Marsh Protection Plan (as defined in Section 29113 of the Public Resources Code) and the certified local protection program (as defined in Section 29111 of the Public Resources Code) if any.
