W <br />A&A <br />TANK TESTING DIV. <br />�M�W�--��/�e <br />August 4, 1988 <br />Mobil Oil Corporation <br />1306 Canal Blvd <br />Richmond, CA 94804 <br />ATTN: Moody Younger <br />RE: # 10-992, 3202 W. Hammer Lane, Stockton, California <br />On July 27, 1988, a Petro-Tite System Test was performed at the <br />above -referenced location. The test was performed by Mike <br />Womack, A & A Technician, Certification #414811422. These <br />underground tank and line tests are Precision Tests in accordance <br />with the NFPA Code 329.02. The NFPA code 329.02 criteria for a <br />tight system is a maximum gain or loss of .05 gallons per hour. <br />Because of the almost infinite variables involved, this is <br />intended to be a mathematical tolerance and is not the permission <br />of actual leakage. <br />During the stand -pipe procedure, the internal liquid hydrostatic <br />pressure applied to the underground tank system is generally two <br />to three times greater than normal liquid storage pressures. <br />This increase in hydrostatic pressure will amplify the indicated <br />rate of leak accordingly. <br />SYSTEM TEST <br />TANK NO. 1 - <br />SIZE - 8,000 gallon glass tank <br />PRODUCT - Regular <br />The test showed a leakage +.040 gallon per hr. <br />Based on the above criteria, we find the system mathematically <br />tight. <br />TANK NO. 2 - <br />SIZE - 10,000 gallon glass tank <br />PRODUCT - Unleaded <br />The test showed a leakage of -.020 gallons per hr. <br />Based on the above criteria, we find the system mathematically <br />tight. <br />
