ATCP 93.503
ATCP 93.503 Product inventory verification at retail facilities. ATCP 93.503(1)(1)
This section applies to any tank system from which products are offered for retail sale to the public that are subject to the requirements of ch.
ATCP 94.
ATCP 93.503 Note
Note: Inventory verification can be particularly effective during regulatory investigations of consumer complaints about the quality of purchased fuels.
ATCP 93.503 Note
Note: The inventory verification specified in this section is not required to conform to the inventory control specifications in API 1621.
ATCP 93.503(2)
(2) To verify and maintain the integrity and quantity of delivered products, product inventory verification shall be conducted monthly for the life of the tank system, and reconciled on a monthly basis, in the following manner:
ATCP 93.503(2)(a)
(a) Inventory volume measurements for regulated substance inputs, withdrawals, and the amount still remaining in the tank are recorded each operating day.
ATCP 93.503(2)(b)
(b) The equipment used is capable of measuring the level of product over the full range of the tank's height, to the nearest one-eighth of an inch.
ATCP 93.503(2)(c)
(c) The regulated substance inputs are reconciled with delivery receipts by measurement of the tank inventory volume before and after delivery. Where tanks are interconnected by a manifold, reconciliation may address all of the interconnected tanks as a group rather than as individual tanks.
ATCP 93.503(2)(d)
(d) Product dispensing is metered and recorded in accordance with applicable requirements in ch.
ATCP 92 for meter calibration or an accuracy of 6 cubic inches for every 5 gallons of product withdrawn.
ATCP 93.503(2)(e)
(e) The measurement of any water level in the bottom of the tank is made to the nearest one-eighth of an inch at least once a month.
ATCP 93.503(3)
(3) The reconciliation under sub.
(2) shall be used to determine whether either of the following are indicated:
ATCP 93.503(3)(b)
(b) Unauthorized product mixing has occurred, as indicated by an unexplained increase or decrease in product level and as addressed in ch.
ATCP 94.
ATCP 93.503 Note
Note: Where inventory control is used as the leak detection method, under s.
ATCP 93.515 (2), the measurements and procedures followed there will satisfy the requirements for inventory verification in this section.
ATCP 93.503 Note
Note: Where statistical inventory reconciliation is used as the leak detection method, under s.
ATCP 93.515 (6), the same data may be used for the statistical inventory reconciliation and the inventory verification in this section, provided the requirements of the statistical inventory reconciliation vendor and of this section are both met, including the monthly reconciliation in this section.
