Tank status results for monthly monitoring <br /> are based on parameters specified by the EPA protocol for SIR methods . <br /> PART B: Comments and Recommendations <br /> O/S listed below represent removals, additions or delivery discrepancies <br /> which were accounted for as part of the SIR analysis . <br /> 1 This tank system showed inconsistent and alternating trends for <br /> the month. Whereas for the most part it appeared to be perfectly <br /> tight, a solid losing trend was depicted for the month of December. <br /> This trend resulted in a 374 gallon loss for the period. We <br /> tested the system for any meter error that could possibly account <br /> for the loss, we did not find one. The loss could be due to an <br /> anomaly that is caused by random measurement errors . Thus, we <br /> were unable to conclusively determine the tank system' s status . <br /> We will be watching it very closely next month. No course of <br /> action is recommended at this point except for proper inventory <br /> collection procedures . Measure the tank accurately to the nearest <br /> 1/8 " on a daily basis . <br /> 2 { 10/26/1992 :DEL 1751 { 11/18/1992 :DEL 1211 111/19/1992 : -204 } <br /> { 11/25/1992 :DEL -173 } 111/30/1992 :DEL -1981 <br /> 3 { See comments for tank 2 above } <br />
