Gov. Code, § 11346.4

(a) At least 45 days prior to the hearing and close of the public comment period on the adoption, amendment, or repeal of a regulation, notice of the proposed action shall be:

(1) Mailed to every person who has filed a request for notice of regulatory actions with the state agency. Each state agency shall give a person filing a request for notice of regulatory actions the option of being notified of all proposed regulatory actions or being notified of regulatory actions concerning one or more particular programs of the state agency.

(2) In cases in which the state agency is within a state department, mailed or delivered to the director of the department.

(3) Mailed to a representative number of small business enterprises or their representatives that are likely to be affected by the proposed action. “Representative” for the purposes of this paragraph includes, but is not limited to, a trade association, industry association, professional association, or any other business group or association of any kind that represents a business enterprise or employees of a business enterprise.

(4) When appropriate in the judgment of the state agency, mailed to any person or group of persons whom the agency believes to be interested in the proposed action and published in the form and manner as the state agency shall prescribe.

(5) Published in the California Regulatory Notice Register as prepared by the office for each state agency’s notice of regulatory action.

(6) Posted on the state agency’s website if the agency has a website.

(b) The effective period of a notice issued pursuant to this section shall not exceed one year from the date thereof. If the adoption, amendment, or repeal of a regulation proposed in the notice is not completed and transmitted to the office within the period of one year, a notice of the proposed action shall again be issued pursuant to this article.

(c) Once the adoption, amendment, or repeal is completed and approved by the office, no further adoption, amendment, or repeal to the noticed regulation shall be made without subsequent notice being given.

(d) The office may refuse to publish a notice submitted to it if the agency has failed to comply with this article.

(e) The office shall make the California Regulatory Notice Register available to the public and state agencies at a nominal cost that is consistent with a policy of encouraging the widest possible notice distribution to interested persons.

(f) Where the form or manner of notice is prescribed by statute in any particular case, in addition to filing and mailing notice as required by this section, the notice shall be published, posted, mailed, filed, or otherwise publicized as prescribed by that statute. The failure to mail notice to any person as provided in this section shall not invalidate any action taken by a state agency pursuant to this article.
