Arco 9 02186, Belshire Environmental Services Page 4 of 5 UNDERGROUND STORAGE TANK RESPONSE PLAN - PAGE 2 VI::'LEAK IINTERCET�ON ANDETGT'Y(' SYSTEM :...:.: ..... ... This information is required only for motor vehicle fuel UST systems constructed per the Alternate Construction Requirements of 23 CCR §2633, and only if the Leak Interception and Detection System (LIDS) does not meet the volumetric requirements of 23 CCR §2631(d)(1) through (5) (i.e., when accounting for rainfall and backfill material, the secondary containment volume is less than 100% of primary tank volume for a single UST; or in the case of multiple USTs in shared secondary containment, 150% of the largest primary tank volume or 10% of aggregate primary tank volume, whichever is greater) AI'IACH AN ADDIIIONAL PAGE TO THIS PLAN CONIAINING IHE FOLLOWING INFORMATION: ➢ The volume of the LIDS in relation to the volume of the primary container; ➢ I'he amount of time the LIDS shall provide containment related to the time between detection of an unauthorized release and cleanup of the leaked substance; ➢ the depth from the bottom of the I IDS to the highest anticipated level of groundwater; ➢ the nature of the unsaturated soils under the LIDS and their ability to absorb contaminants or to allow movement of'contaminants; ➢ The methods and scheduling for removal of all hazardous substances which may have been discharged from primary containment and are located in the unsaturated soils between the primary containment and EZRunclwater, includin the LIDS sum . We will report/record any overfill, spill, or unauthorized release from a UST system as indicated in this plan Recordable Releases: Any unauthorized release from primary containment which the USI operator is able to clean up within eight (8) hours after the release was 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 not cause any deterioration of secondary containment, must be recorded in the facility's monitoring records Monitoring records must include: ➢ The UST operator's name and telephone number; A list of the types, quantities, and concentrations of hazardous substances released; ➢ A description of the actions taken to control and clean up the release; ➢ The method and location of disposal of the released hazardous substances, and whether a hazardous waste manifest was or will be used; A description of actions taken to repair the UST and to prevent future releases; A description of the method used to reactivate interstitial monitoring after replacement or repair of primary containment Reportable Releases: Any overfill, spill, or unauthorized release which escapes from secondary containment (or primary containment if no secondary containment deterioration of secondary containment, is a reportable release Reportable releases are also recordable exists), increases the hazard of fire or explosion, or causes any Within 24 hours after a reportable release has been. detected, or should have been detected, we wilt notify the local agency administering the USI program of the by local agency, remaining stored product/waste will release, investigate the release, and take immediate measures to stop the release If necessary, or if required the be removed from the UST to prevent further releases or facilitate corrective action If an emergency exists we will notify the State Office of Emergency Services 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 that the information is known at the time of filing the report: ➢ T he UST owner's or operator's name and telephone number; ➢ A list of the types, quantities, and concentrations of hazardous materials released; ➢ The approximate date of the release; ➢ The date on which the release was discovered; ➢ I'he date on which the release was stopped; ➢ A description of actions taken to control and/or stop the release; ➢ A description of corrective and remedial actions, including investigations which were undertaken and will be conducted to determine the nature and extent of soil, ground water or surface water contamination due to the release; ➢ The method(s) of cleanup implemented to date, proposed cleanup actions; and a schedule for implementing the proposed actions; ➢ The method(s) and location(s) of disposal of released hazardous materials and any contaminated soils, groundwater, or surface water ➢ Copies of any hazardous waste manifests used for off-site transport of hazardous wastes associated with clean-up activity; ➢ A description of proposed methods for any repair or replacement of UST system primary/secondary containment systems; ➢ A description of additional actions taken to prevent future releases We will follow the reporting procedures described above if any of the following conditions occur: ➢ A recordable unauthorized release can not be cleaned up or is still under investigation within eight (8) hours of detection; ➢ Released hazardous substances are discovered at the UST site or in the surrounding area; ➢ Unusual operating conditions are observed, including erratic behavior of product dispensing equipment, sudden loss of product, or the unexplained presence of water in the tank, unless system equipment is found to be defective and is immediately repaired or replaced, and no leak has occurred; may have occurred, unless the monitoring equipment is found to be ➢ Monitoring results from UST system monitoring equipment/methods indicate that a release defective and is immediately repaired, recalibrated., or replaced, and additional monitoring does not confirm the initial results 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 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.
