Where:
Be2009 = Bypass emissions in 2009, Mg/yr
BREL = Butyl rubber emission limit, Mg organic HAP emissions/Mg butyl rubber produced
Ce2009 = Controlled emissions in 2009, Mg/yr
P2009 = Total elastomer product leaving the stripper in 2009, Mg/yr
UCe2009 = Uncontrolled emissions in 2009, Mg/yr
1.35 = variability factor, unitless
