# 63.5890 How do I calculate an organic HAP emissions factor to demonstrate compliance for continuous lamination/casting operations?
(a) *Compliant line option.* Use Equation 1 of this section to calculate an organic HAP emissions factor in lbs/ton.
Where:
E = HAP emissions factor in lbs/ton of resin and gel coat
WAE<sub>u</sub> = uncontrolled wet-out area organic HAP emissions, lbs per year
WAE<sub>c</sub> = controlled wet-out area organic HAP emissions, lbs per year
O<sub>u</sub> = uncontrolled oven organic HAP emissions, lbs per year
O<sub>c</sub> = controlled oven organic HAP emissions, lbs per year
R = total usage of neat resin plus, tpy
G = total usage of neat gel coat plus, tpy
(b) *Averaging option.* Use Equation 2 of this section to demonstrate compliance.
Where:
E = HAP emissions factor in lbs/ton of resin and gel coat
WAE<sub>ui</sub> = uncontrolled organic HAP emissions from wet-out area i, lbs per year
WAE<sub>ci</sub> = controlled organic HAP emissions from wet-out area i, lbs per year
O<sub>uj</sub> = uncontrolled organic HAP emissions from oven j, lbs per year
O<sub>cj</sub> = controlled organic HAP emissions from oven j, lbs per year
i = number of wet-out areas
j = number of ovens
m = number of wet-out areas uncontrolled
n = number of ovens uncontrolled
o = number of wet-out areas controlled
p = number of ovens controlled
R = total usage of neat resin plus, tpy
G = total usage of neat gel coat plus, tpy
(c) *Combination option.* Use Equations 1 and 2 of this section, as applicable, to demonstrate compliance.
