Cal. Government Code § 11349.3

(a) The office shall either approve a regulation submitted to it for review and transmit it to the Secretary of State for filing or disapprove it within 30 working days after the regulation has been submitted to the office for review. If the office fails to act within 30 days, the regulation shall be deemed to have been approved and the office shall transmit it to the Secretary of State for filing. (b) If the office disapproves a regulation, it shall return it to the adopting agency within the 30-day period specified in subdivision (a) accompanied by a notice specifying the reasons for disapproval. Within seven calendar days of the issuance of the notice, the office shall provide the adopting agency with a written decision detailing the reasons for disapproval. No regulation shall be disapproved except for failure to comply with the standards set forth in Section 11349.1 or for failure to comply with this chapter. (c) If an agency determines, on its own initiative, that a regulation submitted pursuant to subdivision (a) should be returned by the office prior to completion of the office’s review, it may request the return of the regulation. All requests for the return of a regulation shall be memorialized in writing by the submitting agency no later than one week following the request. Any regulation returned pursuant to this subdivision shall be resubmitted to the office for review within the one-year period specified in subdivision (b) of Section 11346.4 or shall comply with Article 5 (commencing with Section 11346) prior to resubmission. (d) The office shall not initiate the return of a regulation pursuant to subdivision (c) as an alternative to disapproval pursuant to subdivision (b).
