80.1280 How are refinery benzene baselines calculated

§ 80.1280 How are refinery benzene baselines calculated?

(a) A refinery's benzene baseline is based on the refinery's 2004-2005 average gasoline benzene concentration, calculated according to the following equation:

$$ Where: BBase = Benzene baseline concentration (volume percent benzene). i = Individual batch of gasoline produced at the refinery from January 1, 2004 through December 31, 2005. n = Total number of batches of gasoline produced at the refinery from January 1, 2004 through December 31, 2005 (or the total number of batches of gasoline pursuant to § 80.1285(d)). Vi = Volume of gasoline in batch i (gallons). Bi = Benzene content of batch i (volume percent benzene).

(b) A refiner for a refinery that included oxygenate blended downstream of the refinery in compliance calculations for RFG or conventional gasoline for calendar years 2004 or 2005 under § 80.69 or § 80.101(d)(4) must include the volume and benzene concentration of this oxygenate in the benzene baseline calculation for that refinery under paragraph (a) of this section.
