§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

WAEu = uncontrolled wet-out area organic HAP emissions, lbs per year

WAEc = controlled wet-out area organic HAP emissions, lbs per year

Ou = uncontrolled oven organic HAP emissions, lbs per year

Oc = 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

WAEui = uncontrolled organic HAP emissions from wet-out area i, lbs per year

WAEci = controlled organic HAP emissions from wet-out area i, lbs per year

Ouj = uncontrolled organic HAP emissions from oven j, lbs per year

Ocj = 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.
