RMC LONESTARA� <br /> 6601 Koll Center Parkway <br /> P.O. Box 5252 <br /> Pleasanton, CA 94566 <br /> (415) 426-8787 <br /> July 13 , 1989 <br /> Mr. William Snavely <br /> San Joaquin Health District <br /> 1601 E. Hazelton Ave. <br /> Stockton, CA 95205 <br /> Re: Underground Tanks at 30350 S. Tracy Blvd. <br /> Dear Mr. Snavely: <br /> As per your visit on July 7, 1989 at our Tracy Aggregate Plant <br /> I have enclosed the following requested information: 1. Copy <br /> of the underground waste oil tank test. 2 . Meter receipt on <br /> calibrations for tanks #1 , #2 , #3 , and #5. 3. Material Safety <br /> Data Sheet for the SC-250 Liquid Asphalt. The quarterly <br /> statement for the tank inventory reconciliation records will <br /> be sent to you by our plant superintendent. <br /> You stated in your inspection report that no letter had been <br /> received from our tank tester indicating that less than one <br /> gallon of product was lost during the precision test on 2-17- <br /> 89. The submittal of the retest from 3-24-89 was our proof <br /> that the tank was tight and that no product was lost during <br /> the first test. <br /> Tank testing is not an exact science, many variables will <br /> effect tank test results. During the test on 2-17 many trucks <br /> loaded with tons of aggregate were driving near the tank being <br /> tested, making it difficult to obtain good test data. The <br /> test results indicated the tank to be tight at -0.047, below <br /> the States 0.05 allowable leakage rate. However, the tank <br /> was retested, at your departments request, due to the required <br /> rounding up to two places to the right of the decimal point. <br /> No repairs were made on the tank before the second test on <br /> 3-24. New test results indicated the tank to be tight at <br /> -0.017. So as you can see, no one tank test will always give <br /> the same results. Therefore it is safe to assume that no <br /> product was lost during the 2-17-89 tank test. <br />
