1. (a) The owner or operator must record any unauthorized release from primary containment that is described in section 25294 of the Health and Safety Code in accordance with this section.

2. (b) The operator's monitoring records, as required under section 2613(c), must include:

   1. (1) The operator's name and telephone number;
   2. (2) A list of the types, quantities, and concentrations of hazardous substances released;
   3. (3) A description of the actions taken to control and clean up the release;
   4. (4) The method and location of disposal of the released hazardous substances (the monitoring record must indicate whether a hazardous waste manifest was or will be used); and
   5. (5) A description of the actions taken to repair the underground storage tank to bring the underground storage tank back into compliance and to prevent future releases, including a description of the actions taken to resume interstitial monitoring after the primary containment is repaired.

3. (c) The integrity of the secondary containment must be reviewed for possible deterioration under the following conditions:

   1. (1) Hazardous substance in contact with the non-integral secondary containment is not suited for long-term exposure to the material used for secondary containment;
   2. (2) The secondary containment is prone to mechanical damage from the mechanical equipment used to remove or clean up the hazardous substance collected in the secondary containment; or
   3. (3) Hazardous substances, other than those stored in the primary containment, are added to the secondary containment to treat or neutralize the released hazardous substance and the added substance or resulting substance from such a combination is not compatible with the secondary containment.
4. (d) If a recordable unauthorized release becomes a reportable unauthorized release due to initially unanticipated facts, the release must be reported pursuant to section 2671.
5. (e) Whenever the Unified Program Agency reviews the operator's monitoring reports and finds that recordable unauthorized releases have occurred, the Unified Program Agency must review the information included in the monitoring records pursuant to subdivision (a), review the permit, and as necessary, inspect the underground storage tank, to determine if construction and monitoring requirements of article 4 or 5 still can be met. If the Unified Program Agency finds that the construction and monitoring requirements of article 4 or 5 can no longer be met, the Unified Program Agency must require the owner or operator to cease operation of the underground storage tank system until appropriate modifications are made to comply with the requirements of article 4 or 5, as appropriate.
