California Laws|Section 11346.8.

                                                
11346.8.  
(a) If a public hearing is held, both oral and written statements, arguments, or contentions, shall be permitted. The agency may impose reasonable limitations on oral presentations. If a public hearing is not scheduled, the state agency shall, consistent with Section 11346.4, afford any interested person or his or her duly authorized representative, the opportunity to present statements, arguments or contentions in writing. In addition, a public hearing shall be held if, no later than 15 days prior to the close of the written
						comment period, an interested person or his or her duly authorized representative submits in writing to the state agency, a request to hold a public hearing. The state agency shall, to the extent practicable, provide notice of the time, date, and place of the hearing by mailing the notice to every person who has filed a request for notice thereby with the state agency. The state agency shall consider all relevant matter presented to it before adopting, amending, or repealing any regulation.
(b) In any hearing under this section, the state agency or its duly authorized representative shall have authority to administer oaths or affirmations. An agency may continue or postpone a hearing from time to time to the time and at the place as it determines. If a hearing is continued or postponed, the state agency shall provide notice to the public as to when it will be resumed or rescheduled.
(c) No state agency may adopt, amend, or repeal a regulation which has been changed from that which was originally made available to the public pursuant to Section 11346.5, unless the change is (1) nonsubstantial or solely grammatical in nature, or (2) sufficiently related to the original text that the public was adequately placed on notice that the change could result from the originally proposed regulatory action. If a sufficiently related change is made, the full text of the resulting adoption, amendment, or repeal, with the change clearly indicated, shall be made available to the public for at least 15 days before the agency adopts, amends, or repeals the resulting regulation. Any written comments received regarding the change must be responded to in the final statement of reasons required by Section 11346.9.
(d) No state agency shall add any material to the record of the rulemaking proceeding after the close of the public
						hearing or comment period, unless the agency complies with Section 11347.1. This subdivision does not apply to material prepared pursuant to Section 11346.9.
(e) If a comment made at a public hearing raises a new issue concerning a proposed regulation and a member of the public requests additional time to respond to the new issue before the state agency takes final action, it is the intent of the Legislature that rulemaking agencies consider granting the request for additional time if, under the circumstances, granting the request is practical and does not unduly delay action on the regulation.
