Cal. SHC § 2396

(a) The commission, in consultation with the State Air Resources Board, shall develop and adopt guidelines for the program consistent with the requirements of this chapter. Guidelines adopted by the commission shall be exempt from the Administrative Procedure Act (Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2 of the Government Code). Prior to adopting the guidelines, the commission shall conduct at least one public hearing in northern California and one public hearing in southern California to review and provide an opportunity for public comment. The commission shall adopt the final guidelines no sooner than 30 days after the commission provides the proposed guidelines to the Joint Legislative Budget Committee and the transportation policy committees in the Senate and the Assembly.

(b) The guidelines adopted pursuant to subdivision (a) may include streamlining of project delivery by authorizing regional agencies to seek commission approval of a letter of no prejudice that allows the agency to expend its own funds for a project programmed in a future year of the adopted program of projects, in advance of allocation of funds to the project by the commission, and to be reimbursed at a later time for eligible expenditures. A letter of no prejudice shall only be available to local or regional transportation agencies for moneys that have been identified for future allocation to the applicant agency. Moneys designated for the program shall only be reimbursed when there is funding available in an amount sufficient to make the reimbursement.
