Petroleum <br /> 1261 E. 9th Street <br /> Pomona, Ca. 91766 <br /> V <br /> Re: USA Petroleum, 2500 West Lodi , Lodi , Ca. <br /> Dear Mr. Green: <br /> On March6, 1989 a Petro Tite System Test was performed at <br /> the above-referenced location. The test was performed by George <br /> Yarbrough, LCI Technician. The NFPA Code 329.02 criteria for a <br /> tight system is a maximum loss of .05 gallons per hour. Because <br /> of the almost infinite variables involved , this is not in'Cend'eir' <br /> to be a mathematical tolerance and is not the permission of <br /> actual leakage. , <br /> During the stand-pipe test <br /> 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. 1 - North . <br /> Size - 12,000 gallons <br /> Product - Regular <br /> The test showed a minus .0145 gallons per hour. Based on the <br /> above criteria, we find the tank tested mathematically tight . <br /> Tank No. 2 - Center <br /> Size - 12,000 gallons <br /> Product - Unleaded <br /> The test showed a minus .0195 gallons per hour. Based on the <br /> above criteria, we find the tank tested mathematically tight . <br /> Tank No. 3 - South <br /> Size - 12,000 gallons <br /> Product - Super Unleaded <br /> The test showed a minus .0275 gallons per -hour. Based on the <br /> above criteria, we find the tank tested mathematically tight . <br /> 1054 North V Street • Post Office Box 1220 • Tulare, California 93275 • (209) 688-1980 <br /> A+ <br />
