11.1.2. Upon Whom Tax Imposed. - The consumers sales and service tax and use tax imposed on the sale or use of gasoline and special fuel within this State shall be collected on the actual metered gallons delivered at the first point of delivery within this State to a person not excepted from tax under the sale for resale exception set forth in Section 11.1 of these regulations. For periods beginning on or after October 1, 1987, the quantity delivered shall be either the actual metered gallons delivered or the quantity delivered being calculated by converting to 60E Fahrenheit the quantity transferred by means of either temperature compensating meters approved by the West Virginia Department of Labor, Weights and Measures Division, or by mathematical conversion using American Petroleum Institute (API) ASTM-IP Petroleum Measurement Tables for specific gravity and temperature. This measure shall be the same as that required for calculation of the Gasoline and Special Fuel Excise Tax imposed by W. Va. Code ''11-14-1 et seq. and 11-14A-1 et seq. If the metered quantity delivered is not determined by temperature compensating meter, as aforesaid, and the taxpayer does not convert said gallons delivered to temperature adjusted gallons or, after making a mathematical conversion fails to keep and maintain records to support and substantiate the conversion, then the amount of tax due shall be determined by the number of metered gallons of gasoline or special fuel delivered without adjustment for temperature. Use of the conversion method for determining the quantity of gasoline or special fuel delivered necessitates that the conversion adjustment be made on each invoice and must continue to use that method for the entire tax year for the consumers sales and service tax and the use tax. Example. - What is the volume at 60EF of 10,000 U.S. gallons of oil measured at 34EF when the gravity of the oil is 64.80 API at 60EF?
Enter the table in the column "API Gravity at 60EF," headed 64E API, and note that against an "Observed Temperature of 34EF" the factor is . . . 1.0168
Likewise, from the column headed 65EF API, note that for the observed temperature of 34EF the factor is . . . 1.0170
This represents an increase of 0.0002 in the factor for an increase of 1.0E API. Therefore, by simple proportion and increase in gravity from 64.0 to 64.80E API increases the factor by 0.8 x 0.0002 or . . . 0.0002
Then, one U.S. gallon of oil having a gravity of 64.80E API at 60EF and measured at 34EF occupies at 60EF a volume of 1.0168 + 0.0002 or . . . 1.0170 U.S. Gallons
Therefore, 10,000 U.S. gallons measured at 34EF occupy at 60EF a volume of 10,000 x 1.0170 or . . . 10,170 U.S. Gallons
