CHEVRON LEAK RESPONud PLAN: Double Wall Tanks All calls to Maintenance from Chevron Products Company service stations (both Company owned/operated and Company owned/leased to Operator) come into Central Maintenance Dispatch in San Ramon, California via (800) 423-3528. This includes calls to report spills, leaks, dispensers damaged by cars or alarms triggered by leak detection equipment. 7 days a week, 24 hours a day Maintenance Dispatch is operated by trained personnel. Contractors, mechanics and/or equipment can be dispatched to the site by one of the Maintenance Dispatchers. This location works from a Computerized Maintenance Management system which has a matrix within it that lists the Proprietary mechanic and the contractors (by specialty) available to respond to an emergency in a specific zone. Hard copy binders of contractor/Mechanic lists are kept at these locations for backup in case the computer system is down. Upon report of product in the annular space/secondary containment, Maintenance Dispatch will do the following: If the caller is an Operator, immediate inquiry will be made regarding any losses during recent inventory reconciliation. If the records are not available to the caller, the Retail ESH Specialist will be contacted to review records at the site. Dispatch will immediately contact a maintenance mechanic or contractor to: 11 Verify there is liquid in the annular space; 2) determined if the liquid is hydrocarbon or water. a) If investigation verifies that there is product in the annular space, Dispatch will immediately make arrangements to pump the annular space dry. Pumping of product or water will only be handled by a Maintenance Mechanic or Chevron Approved contractor, product or water removed will be appropriately manifested, hauled by a licensed transporter, and disposed of at a Chevron approved site licensed to accept the material. b) The Mechanic or Contractor will attempt to determine if the product has come from the primary tank or some other source. c) If it is obvious (without doing a precision test) that the product has come from the primary tank, Dispatch will immediately arrange for a tank pump out and repair/replace activities will begin. In the case of repair, the Tank Test coordinator will handle repair arrangements and precision testing. If replacement is required, the appropriate zone Engineer will handle the project. d) If the product in the annular space is water entering the tank from the outer shell, repair/replacement activities will take place as noted in "c" above. e) If it is determined that the liquid in the annular space is water and there are no product losses from the primary tank and no indication of additional water entering the tank, the Tank Test Coordinator will arrange for a precision test of the of the annular space. Based on the results, repair/replacement activities will take place as noted in "c". f) If the Maintenance Mechanic or Contractor is unable to determine how the liquid entered the secondary containment the Tank Test Coordinator will immediately have the appropriate precision tests conducted. g) If it is determined at any time during the process that there has been a release (defined as product leaking from the primary tank to the annular space or water entering the annular space from the back fill), a leak report will be prepared and forwarded to the Marketing Assistant-Compliance. The MA - compliance is responsible for reporting to all regulatory agencies as required. In addition, the Tank Test Coordinator will prepare and forward a Fiberglass failure report.
