  • (2) The inventory reconciliation must include

    • (a) the measurement of the level of water and the combined level of water and petroleum product or allied petroleum product in every storage tank of the storage tank system at least every seven days unless the storage tank system is located at a fuel dispensing station, in which case the levels must be measured each day the station is in operation; and

    • (b) a comparison of the measurements with readings of any meters that measure the volume of liquid transferred and the calculation of any gain or loss of liquid each time the measurements are taken.

  • (3) The continuous external horizontal aboveground tank leak monitoring must

    • (a) be carried out using a sensor cable system designed for installation beneath the horizontal aboveground tank and surrounding its perimeter dripline in order that any leak will be detected before any liquid moves beyond the tank’s perimeter;
