Use Equation 1 of this section to calculate an organic HAP emissions factor in lbs/ton.\nWhere:\nE = HAP emissions factor in lbs/ton of resin and gel coat\nWAEu = uncontrolled wet-out area organic HAP emissions, lbs per year\nWAEc = controlled wet-out area organic HAP emissions, lbs per year\nOu = uncontrolled oven organic HAP emissions, lbs per year\nOc = controlled oven organic HAP emissions, lbs per year\nR = total usage of neat resin plus, tpy\nG = total usage of neat gel coat plus, tpy\n(b) Averaging option. Use Equation 2 of this section to demonstrate compliance.\nWhere:\nE = HAP emissions factor in lbs/ton of resin and gel coat\nWAEui = uncontrolled organic HAP emissions from wet-out area i, lbs per year\nWAEci = controlled organic HAP emissions from wet-out area i, lbs per year\nOuj = uncontrolled organic HAP emissions from oven j, lbs per year\nOcj = controlled organic HAP emissions from oven j, lbs per year\ni = number of wet-out areas\nj = number of ovens\nm = number of wet-out areas uncontrolled\nn = number of ovens uncontrolled\no = number of wet-out areas controlled\np = number of ovens controlled\nR = total usage of neat resin plus, tpy\nG = total usage of neat gel coat plus, tpy\n(c) Combination option.
