Compliance with average standards.

§ 1090.700 Compliance with average standards.

(a) Compliance with the sulfur average standard. For each of their facilities, a gasoline manufacturer must demonstrate compliance with the sulfur average standard in § 1090.205(a) by using the equations in paragraphs (a)(1) and (2) of this section.

(1) Compliance sulfur value calculation. (i) The compliance sulfur value is determined as follows:

CSVy = Stot,y + Ds,(y−1) + DS_Oxy_Total − CS
Where: CSVy = Compliance sulfur value for compliance period y, in ppm-gallons. Stot,y = The total amount of sulfur produced in compliance period y, per paragraph (a)(1)(ii) of this section, in ppm-gallons. Ds,(y−1) = Sulfur deficit from the previous compliance period, per § 1090.715(a)(1), in ppm-gallons. DS_Oxy_Total = The total sulfur deficit from BOB recertification, per § 1090.740(b)(2), in ppm-gallons. CS = Sulfur credits used by the gasoline manufacturer, per § 1090.720, in ppm-gallons.

(ii) The total amount of sulfur produced is determined as follows:

Where: Vi = The volume of gasoline produced or imported in batch i, in gallons. Si = The sulfur content of batch i, in ppm. n = The number of batches of gasoline produced or imported during the compliance period. i = Individual batch of gasoline produced or imported during the compliance period.

If the calculation of Stot,y results in a negative number, replace it with zero.

(2) Sulfur compliance calculation. (i) Compliance with the sulfur average standard in § 1090.205(a) is achieved if the following equation is true:

(ii) Compliance with the sulfur average standard in § 1090.205(a) is not achieved if a deficit is incurred two or more consecutive years. A gasoline manufacturer incurs a deficit under § 1090.715 if the following equation is true:
