Stockton, CA <br /> Dear George: <br /> On December 26, 1991 a Petro Tite System-Test was performed;,'�yV <br /> at the above-referenced location. The test was , performed bY';`?�d� <br /> George Yarbrough, Franzen Hill Technician. The NFPA Code 329.02:`,1-•; <br /> criteria for a tiqht system is a maximum loss of 05 gallons per';= ;?+ '' <br /> hour . because of the almost infinite variables involved, this is af. <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 i,$: <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 - 10,000 Gallons <br /> Product -Unleaded "; <br /> The test showed a minus .0145 gallons per hour . Based on <br /> above criteria, we find the tank tested mathematically tight . 6 <br /> Tank: No. 2 - South <br /> Size - 10,000 Gallons ''"'� <br /> Product - Diesel . <br /> The test showed a minus .0155 gallons per hour . Based on the <br /> above criteria, we find the tank: tested matematically tight . <br /> This concludes our test and findings. If you have any <br /> questions regarding the results, please contact me. For your <br /> convenience a copy of the test results have been sent to the <br /> County. <br /> 1100 Na:- _sreet.T,lare.
