Vn.L'X J tX ArUA U - °1 <br />INSPECTIONS TO BE CISUCTED BY DEALER <br />1. Daily reconcilig ion shall be made of the I entory Control Records. <br />2. Daily visual inspection for leaks shall be made in the areas of: <br />- Submerged pump <br />- Tank fill (also inspected after each delivery) <br />3. Dealer MUST be aware that a reduction in product flow to 3 gallons per <br />minute (gpm) indicates a potential leak. <br />SECONDARY CONTAINMENT MONITORING PROCEDURE <br />Tank or Piping Secondary Containment (annular space or Piping Trench <br />Liner) shall be monitored daily by the dealer, unless a less frequent <br />period is allowed. This is done to determine if product is leaking from <br />the primary container or if water is entering from an outside source. <br />This procedure is not necessary if an electronic monitoring system is <br />installed to monitor these items. Contact your UNOCAL representative for <br />monitoring port locations. <br />1. Use a gauge stick (dipstick) to detect any liquid in the tank annular <br />space, double wall piping monitoring ports, or piping trench liner <br />monitoring wells. Lower the stick slowly until it hits the bottom of <br />the tank annular space. <br />2. Slowly pull the stick back out and observe whether the stick has been <br />discolored by liquid. If product and/or water is detected, <br />immediately contact your representative. <br />3. Write this number down, and repeat the same procedure. If the two <br />numbers are not close, repeat the procedure until the numbers agree. <br />4. Enter the final number in the "Secondary Containment Recording Sheet <br />(attached). <br />NOTE: Piping trench monitoring wells consist of slotted PVC pipe which <br />allows liquid intrusion and a manhole for access. Wells are located at <br />the lowest point of the fiberglass trench liner. <br />RECORD KEEPING FOR DOUBLE-WALL TANKS & PIPING <br />1. Keep track daily of the liquid level on the "Secondary Containment <br />Recording Sheet". <br />2. If ANY fuel and/or water is discovered in the trench liner, call your <br />representative IMMEDIATELY, and explain the situation. <br />3. If the representative has been notified, but after 8 hours it has not <br />been possible to remove all the liquid from the secondary containment, <br />dealer must contact the local agency shown on the cover sheet. <br />ELECTRONIC MONITORING SYSTEMS <br />If this station is equipped with an electronic monitoring system for <br />underground tanks and piping, in the event of a leak in the primary <br />containment, product will be contained in the annular space. The sensors <br />for the electronic monitoring system are located at the low end of each <br />tank, and at the low end of the piping where the product will drain back <br />into the tank. There may be sensors at additional locations. Sensors <br />will signal the presence of a leak. <br />If a leak is discovered, the "Unauthorized Release Report" must be sent <br />to UNOCAL within 24 hours. The "Release Evaluation Checklist" must be <br />attached to the "Quarterly Report". <br />Page 6 of 10 <br />
