Where:
ERMBS = Emission rate of organic HAP or TOC from continuous process vents, kg/Mg product.
Ei = Emission rate of organic HAP or TOC from continuous process vent i as calculated using the procedures specified in § 63.116(c)(4) , kg/month.
PPM = Amount of polymer produced in one month as determined by the procedures specified in § 63.1318(b)(1)(ii) , Mg/month.
n = Number of continuous process vents.
Where:
PR = Percent reduction
Hj = Number of operating hours in a year for control device j.
Ei = Mass rate of TOC or total organic HAP at the inlet of control device j, calculated as specified in § 63.1325(f) , kg/hr. This value includes all continuous process vents, batch process vents, and aggregate batch vent streams routed to control device j.
Eo = Mass rate of TOC or total organic HAP at the outlet of control device j, calculated as specified in § 63.1325(f) , kg/hr.
Hk = Number of hours of operation during which positive flow is present in uncontrolled continuous process vent or aggregate batch vent stream k, hr/yr.
Eku = Mass rate of TOC or total organic HAP of uncontrolled continuous process vent or aggregate batch vent stream k, calculated as specified in § 63.1325(f)(4) , kg/hr.
AEunc = Mass rate of TOC or total organic HAP of uncontrolled batch process vent l, calculated as specified in § 63.1325(f)(4) , kg/yr.
n = Number of control devices, uncontrolled continuous process vents and aggregate batch vent streams, and uncontrolled batch process vents. The value of n is not necessarily the same for these three items.
