Notwithstanding any other provision of law, the agency is not required to promulgate rules and regulations in order to establish or operate a mortgage refinance program. Instead, that program may be established by the governing board of the agency through resolutions adopted by that board, and operated by the agency in accordance with resolutions adopted by the board. Those resolutions shall be exempt from the requirements of the Administrative Procedure Act (Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2 of the Government Code).
