EXHIBIT A RETROFIT LOCATIONS INVENTORY RECONCILIATION - Performed daily by facility operators. Variations in excess of 100 gallons daily, 5% of thruput but no greater than 350 gallons weekly and 0 .5% of thruput but no less than 100 gallons monthly will be reported. To improve inventory reconciliation accuracy, Texaco is installing automatic continuous tank gauging instrumentation for each tank (Veeder-Root TLS-250/ literature attached) . Results of inventory reconciliation will be reported to administering agency quarterly. TANK TESTING - Tank testing will be performed quarterly by automatic tank gauging system' s leak detect mode which detects leaks to an accuracy of 0 .20 gallons per hour (at 24-hour locations , tanks will be taken out of service for 6 hours per quarter to run this test) . Results of tank tests will be reported to administering �GT-� agency quarterly. LINE PRESSURE MONITORING SYSTEM - In addition to Red Jacket leak detectors , pressurized product lines will be continuously moni- tored by electronic line pressure monitor (K & E Associates PMS-800/literature attached) which will disable submersible pumps upon pressure drop in line corresponding to a leak of 0 .05 gallons per hour. SPILL CONTAINMENT BOX - Spill containment boxes will be installed on all fill lines regardless of groundwater depth. WASTE OIL TANKS - All waste oil tanks will either be removed or replaced with double wall tanks. Sensors (K & E) will be in- stalled in the annular space of each replacement tank to contin- uously monitor for leakage. We feel that this proposed method of compliance fully meets the intent of new regulations established to protect our environment. A significant advantage of this system is that we will be able to detect leakage almost immediately, whereas other methods of leak detection such as relying on precision testing or groundwater wells can allow substantial undetected leakage.
