§ 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.
