Cal. Health & Safety Code § 25199.10

(a) If an appeal is filed pursuant to subdivision (b), (d), or (e) of Section 25199.9, or paragraph (3) of subdivision (c) of Section 25199.9, the Governor or the Governor’s designee shall determine within five working days whether the proponent has obtained all permits for the specified hazardous waste facility project which can be obtained before construction from those responsible agencies which are state agencies, and which were obtainable when the appeal was filed. If, because the application for the appeal is incomplete, the Governor or the Governor’s designee is unable to determine, within five working days, whether or not the appeal board should be convened, the Governor or the Governor’s designee shall return the application for appeal to the proponent or interested party who filed the appeal. The proponent or interested party shall resubmit the completed application for an appeal within 20 calendar days after receiving the returned appeal and if the proponent or interested party fails to do so, the Governor or the Governor’s designee shall not reconsider whether to convene an appeal board.
(b) If the Governor or the Governor’s designee determines, pursuant to subdivision (a), that the proponent has obtained all permits for the specified hazardous waste facility project which can be obtained before construction from those responsible agencies which are state agencies, or if an appeal is filed pursuant to paragraph (1) of subdivision (c) of Section 25199.9, the Governor or the Governor’s designee shall convene an appeal board within 30 days after making that determination or receiving that appeal, by requesting the League of California Cities and the County Supervisors Association of California to each nominate persons for appointment to an appeal board, as specified in paragraphs (6) and (7) of subdivision (c).
(c) An appeal board shall consist of seven members, five of whom shall be the members listed in paragraphs (1) to (5), inclusive, and two of whom shall be separately appointed for each particular appeal, as provided in paragraphs (6) and (7). An appeal board shall consist of the following members:
1. (1) The Director of Toxic Substances Control.
2. (2) The Chairperson of the State Air Resources Board.
3. (3) The Chairperson of the State Water Resources Control Board.
4. (4) A member of a county board of supervisors appointed by the Senate Committee on Rules who shall be selected from the persons nominated by the County Supervisors Association of California. The appointment shall be for a period of four years, but shall terminate earlier if the appointee does not continue in office as a member of a board of supervisors.
5. (5) A member of a city council appointed by the Speaker of the Assembly who shall be selected from the persons nominated by the League of California Cities. The appointment shall be for a period of four years, but shall terminate earlier if the appointee does not continue in office as a member of a city council.
6. (6) A member of a county board of supervisors appointed by the Speaker of the Assembly who shall be selected from the persons nominated by the County Supervisors Association of California. The member shall be from the county in which the specified hazardous waste facility project which is the subject of the appeal is located. However, if the member appointed pursuant to paragraph (4) is from the county in which the specified hazardous waste facility project is located, the member appointed pursuant to this paragraph shall not be from that same county. If the appointee appointed pursuant to this paragraph does not continue in office as a member of a board of supervisors for the duration of the appeal for which the appointment was made, the appointment shall terminate and a new appointment shall be made.
7. (7) A member of a city council appointed by the Senate Committee on Rules who shall be selected from the persons nominated by the League of California Cities. The member shall be from the city in which the specified hazardous waste facility project which is the subject of the appeal is located, or from the city which the Governor or the Governor’s designee determines to be the most directly affected by the project if the project is not located in a city. However, if the member appointed under paragraph (5) is from a city in the county in which the specified hazardous waste facility project is located, the member appointed under this paragraph shall be from a city in a different county. If the appointee appointed pursuant to this paragraph does not continue in office as a member of a city council for the duration of the appeal for which the appointment was made, the appointment shall terminate and a new appointment shall be made.
(d) The appeal board shall issue the final decision upon an appeal in writing and the members of the appeal board shall sign the decision.
(e) The Director of Toxic Substances Control, the Chairperson of the State Air Resources Board, and the Chairperson of the State Water Resources Control Board may designate an alternate to attend any meetings or hearings of an appeal board in that person’s place, except that the alternate may not vote on a final decision on an appeal or sign the written decision in place of the person for whom the person serves as alternate.
(f) The Governor or the Governor’s designee shall designate staff to serve the appeal board.
