INSPECTIONS TO BE COORDINATED BY UNOCAL <br /> YEARLY INSPECTIONS AND TESTING <br /> Yearly testing shall be made of the following: <br /> 1. Pressurized piping systems shall be monitored using in-line leaf detectors. Leak <br /> detectors shall be tested annually for proper operation. Dealer MUST be aware that a <br /> reduction in product flow to 3 gallons per minute (gpm) indicates a potential piping <br /> leak. <br /> 2. Tanks and piping shall be tested annually for tightness, using a State-Certified test <br /> system. (For non-secondarily contained tanks and piping only) . <br /> 3. Electronic monitoring systems shall be tested annually for proper operation. (For <br /> secondarily contained tanks and piping only) . <br /> 4. Dispenser core holes, shear valves, and blending valves shall be annually inspected by <br /> Unocal for signs of leakage. <br /> 5. Dispenser meters (recording total sales in gallons) shall be calibrated once annually <br /> be Unocal. Any additional calibration will be the respow ilitV of the dealer. Use <br /> the "Dispenser Meter Calibration Form". <br /> VADOSE/GROUNDWATER MONITORING WELLS <br /> (This section not applicable unless "Monitoring Methods" line on cover sheet shows '"Vadose <br /> Wells" or "Groundwater Wells".) <br /> The monitoring of vadose wells and groundwater monitoring wells is contracted out to <br /> Applied Geo Systems. Monitoring is performed monthly for vapor analysis of the vadose <br /> wells and subjective analysis for traces of product in the groundwater monitoring wells. <br /> Monitoring is performed quarterly for laboratory analysis of groundwater samples. <br /> Monitoring records are maintained on-site in an orange binder in the dealer's office, and <br /> are available for inspection. <br /> Page 8 of 10 <br />
