Health & Saf. Code, § 25535

(a) An owner or operator of a stationary source submitting an RMP pursuant to this article shall submit the RMP to the unified program agency after the RMP is certified as complete by a qualified person and the stationary source owner or operator. The unified program agency shall review the RMP and may authorize the air pollution control district or air quality management district in which the stationary source is located to conduct a technical review of the RMP. If, after review by the unified program agency and technical review, if any, by the air pollution control district or air quality management district, the unified program agency determines that the stationary source’s RMP is deficient in any way, the unified program agency shall notify the stationary source of these defects. The stationary source shall submit a corrected RMP within 60 days of the notification of defects, unless granted a one-time extension of no more than 30 days, of the notice to correct the RMP by the unified program agency. Failure to fully comply with this notice or the unified program of this section shall be deemed a violation of this article for purposes of Section 25540.

(b) Upon implementation of an RMP, the stationary source shall notify the unified program agency that the RMP has been implemented and shall summarize the steps taken in preparation and implementation of the RMP.

(c) The stationary source shall continue to carry out the program and activities specified in the RMP at the stationary source after the unified program agency has been notified pursuant to subdivision (b).

(d) The owner or operator of the stationary source shall implement all programs and activities in the RMP before operations commence, in the case of a new stationary source, or before any new activities involving regulated substances are taken, in the case of a modified stationary source.
