For 8 of the 12 purchases the gallons in the tank per the dipstick reading on the ticket immediately after the fuel delivery was less than what we expected based on our computations. As a result we could not conclude that the District actually received the gallons billed. Possibility of Fuel Leakage 10-Day Fuel Reconciliation Worksheet Our review revealed that the District did not comply with the State s requirements for investigating excessive fuel variances shown on the 10-Day Worksheet. We examined nine 10-Day Worksheets and found five instances where variances were greater than the tolerable amount of 30 gallons. In all five instances the explanation written by the District on the worksheet did not indicate that the all possible causes for the variances were investigated. Thus there was an increased risk that leakage factors may have existed thus requiring that the NYS Department of Environmental Conservation be notified according to 6 NYCRR Part d and the tanks be taken out of service until an inspection or a tightness test was performed the cause was determined and necessary repairs or replacements were made. Failure to comply with 6 NYCRR Part d may also expose the District to fines. We examined 33 days of fuel inventory records kept on or after September 17 2008 the date when the District implemented the use of the 10-Day Inventory Reconciliation Worksheets to determine if the data recorded in the worksheets agreed with the source information. Our review revealed that for 3 of the 33 days there were transcription errors which were not detected. Had a supervisory review of the accuracy of the 10-Day Worksheet been performed these errors would have been detected. We were able to determine that in these 3 cases the errors did not adversely impact the tolerable variance for each of these three 10-day periods. Audit Recommendations The District should a take the necessary steps to change .
