<br />VI. LEAK INTERCEPTION AND DETECTION SYSTEM
<br />This information is required only for motor vehicle fuel UST systems consWcteA per the Alternate Construction Requirements of23 CCR §2633, and only if the Leak
<br />Interception and Detection System (LIDS) doe n meet the volumetric requirements of 23 CCR §2631(d)(1) through (5) (i.e., when accounting for rainfall and
<br />backfill material, the secondary containment volume is less than 1001/6 of primary tank volume for a single UST; or in the case of multiple USTs in shared secondary
<br />containment. 150'/e of the largest primary tank volume or 10% ofaggregate primary tank volume, whichever is greater).
<br />ATTACH AN ADDITIONAL PAGE TO THIS PLAN CONTAINING THE FOLLOWING INFORMATION:
<br />> The volume of the LIDS in relation to the volume of the primary container,
<br />> The amount of time the LIDS shall provide containment related to the time between detection of an unauthorized release and cleanup of the leaked substance:
<br />> The depth from the bummn of the LIDS to the highest anticipated level of groundwater,
<br />> The nature of the unsaturated soils under the LIDS and their ability to absorb contaminants or in allow movement of contaminants;
<br />> The methods and scheduling for removal of all hazardous substances which may have been discharged from primary containment and are located in the
<br />unsaturated soils between the primary containment and groundwater. including the LIDS sump.
<br />VII. REPORTING AND RECORD KEEPING
<br />We will report/record any overfill, spill, or unauthorized release from a UST system as indicated in this plan.
<br />Recordable Releases: Any unauthorized release from primary containment which the UST opemmr is able to clean up within eight (8) hours after the release was
<br />detected or should reasonably have been detected, and which does not escape from secondary containment, does not increase the hazard of fire or explosion, and does
<br />not cause any deterioration ofsecondary containment, most be recorded in the facihity's monitoring records. Monitoring records must include:
<br />> The UST operator's name and telephow number,
<br />> A list of the types, quantities, and concentrations of hazardous substances released;
<br />> A description of the actions taken to control and clean up the release;
<br />> The method and location of disposal of the released hazardous substances, and whether a hazardous waste manifest was or will be used;
<br />> A description of actions taken to repair the UST and to prevent future releases;
<br />> A description of the method used to reactivate interstitial monitoring after replacement or repair of primary containment.
<br />Reportable Releases: Any overfill, spill, or unauthorized release Which escapes from secondary containment (or primary containment if no secondary containment
<br />exists), increases the hazard of fire or explosion, or causes any deterioration of secondary containment, is a reportable release. Reportable releases are also recordable.
<br />Within 24 hours alter a reparable release has been detected, or should have been detected, we will notify the local agency administering the UST program of the
<br />release, investigate the release, and take immediate Treasures to stop the release. If necessary, or if required by the local agency, remaining stored product/waste will
<br />be removed from the UST to prevent further releases or facilitate corrective action. (fan emergency exists, we will notify the State Office of Emergency Services.
<br />Within five (5) working days of a reportable release, we will submit to the local agency a full written report containing all of the following information to the extent
<br />that the information is kressa at the time of filing the report:
<br />> The UST ommes or opemlor's name and telephone number,
<br />A list of the types, quantities, and concentrations of hazardous materials released;
<br />r The approximate date of the rciease:
<br />The dale on which the release was discovered:
<br />The date on which the release was stopped:
<br />> A description of actions taken to conlml and/or stop the release:
<br />A description of collective and remedial actions, including investigations which were undertaken and will be conducted to determine the nature and extent of
<br />soil, ground water or surface water contamination due lode release:
<br />> The method(s) of cleanup implemented to date, proposed cleanup actions, and a schedule for implementing the proposed actions;
<br />The method(s) and location(s) of disposal of released hazardous materials and any contaminated soils, groundwater, or surface water.
<br />Copies of any hazardous waste manifests used for off-site transport of hazardous wastes associated with clean-up activity;
<br />> A description of proposed methods for any repair or replacement of UST system primary/secondary containment systems;
<br />> A description of additional actions taken to prevent future releases.
<br />We will follow the reporting procedures described above if any of the following conditions occur:
<br />i A recordable unauthorized release can not be cleaned up or is still under investigation within eight (8) hours of detection;
<br />i Released hazardous substances arc discovered at the UST site or in the surrounding area;
<br />> Unusual operating conditions are observed, including erratic behavior of product dispensing equipment, sudden loss of product, or the unexplained presence of
<br />water in the Lank, unless system equipment is found to be defective and is immediately repaired or replaced, and no leak has occurred;
<br />> Monitoring results from UST system monitoring equipment/methods indicate that a release may have occurred, unless the monitoring equipment is found to be
<br />defective and is immediately repaired, recalibrated, or replaced, and additional monitoring does not confirm the initial results.
<br />Record Retention: Monitoring records and written reports of unauthorized releases must be maintained on-site (or off-site at a readily available location, if approved
<br />by the local agency) for at least 3 years. Hazardous waste shipping/disposal records (e.g., manifests) must be maintained for at least 3 years from the date of shipment.
