Health & Saf. Code, § 25504

(a) The Legislature hereby finds and declares that persons attempting to do business in this state are increasingly experiencing excessive and duplicative regulatory requirements at different levels of government.

(b) To streamline and ease the regulatory burdens of doing business in this state, compliance with Section 25505 shall also suffice to meet the requirements for a Hazardous Materials Management Plan and the Hazardous Materials Inventory Statement as set forth in the California Fire Code and its appendices, to the extent that the information in the California Fire Code is contained in Section 25505.

(c) The unified program agency shall provide access to the information collected in the statewide information management system to emergency response personnel on a 24-hour basis.

(d) The enforcement of this article by unified program agencies and the California Fire Code by those agencies required to enforce the provisions of that code shall be coordinated.

(e) (1) Notwithstanding Section 13143.9, and the standards and regulations adopted pursuant to that section, a business that files the inventory of information required by this article and the addendum adopted pursuant to paragraph (4), if required by the fire code official, shall be deemed to have met the requirements for a Hazardous Materials Inventory Statement, as set forth in the California Fire Code and its appendices.

(2) Notwithstanding Section 13143.9, and the standards and regulations adopted pursuant to that section, a business that establishes and maintains a business plan for emergency response to a release or a threatened release of a hazardous material in accordance with Section 25505, shall be deemed to have met the requirements for a Hazardous Materials Management Plan, as set forth in the California Fire Code and its appendices.

(3) Except for the addendum required by the fire code official pursuant to paragraph (4), the unified program agency shall be the sole enforcement agency for purposes of determining compliance pursuant to paragraphs (1) and (2).

(4) The secretary shall, in consultation with the unified program agencies and the Office of the State Fire Marshal, adopt by regulation a single comprehensive addendum for hazardous materials reporting for the purposes of complying with subdivisions (b) and (c) of Section 13143.9 and subdivision (b) of Section 25506. The unified program agency shall require businesses to annually use that addendum when complying with subdivisions (b) and (c) of Section 13143.9 and subdivision (b) of Section 25506. A business shall file the addendum with the unified program agency when required by the fire code official pursuant to subdivision (b) of Section 13143.9 or subdivision (b) of Section 25506.

(f) Except as otherwise expressly provided in this section, this section does not affect or otherwise limit the authority of the fire code official to enforce the California Fire Code.
