LCI <br />LIQUID CONSTRUCTION, INC. <br />October 13, 1986 <br />Arco <br />P.O. Box 5811 <br />San Mateo, California 94402 <br />Attention: Carl Seward <br />Re: Arco 46100 <br />25775 S. Paterson Pass Rd/Hwy 5, Tracey, Calif. <br />Dear Mr. Seward: <br />ENVIROMENTAL HEALTH <br />FERMIT/SERVICES <br />On October 7, 1986, a Petro Tite System Test was performed at <br />the above -referenced location. The test was performed by <br />Abel Hernandez, LCI Technician. The NFPA Code 329.02 criteria <br />for a tight system is a maximum loss of .05 gallons per hour. <br />Because of the almost infinite variables involved, this is <br />not intended to be a mathematical tolerance and is not the <br />permission of actual leakage. <br />During the stand -pipe test procedure, the internal liquid <br />hydrostatic pressure applied to the underground tank system is <br />generally two to three times greater than normal liquid storage <br />pressures. This increase in hydrostatic pressure will amplify <br />the indicated rate of leak accordingly. <br />SYSTEM TEST <br />Tank No. i ----W= <br />Size - 6,000 Gallons <br />Product - Super Unleaded <br />The test showed a plus .016 gallons per hour. <br />Based on the above criteria, we find the tank tested <br />mathematically tight. <br />Tank No. 2, 3 - West Center, Middle Center <br />Size - 6,000 Gallons/Siphon <br />Product - Unleaded <br />The test showed a minus 1.000 gallons per hou <br />Based on the above criteria, we in e tank tested <br />mathematically not tight. <br />1054 North 'J' Street 0 Post Office Box 1220 0 Tulare, California 93275 0 (209) 688-1980 <br />
