To do this, sum the product of eachindividual organic HAP emissions factor calculated in 40 CFR 63.5810(a)(1) and theamount of neat resin plus and neat gel coat plus usage that corresponds to the individualfactors and divide the numerator by the total amount of neat resin plus and neat gel coatplus used in that operation type as shown in Equation 2 below.Equation 2:Actual Operation Organic HAP Emission Factor~ (Actual Process Stream EFi * Maleriali)i-In2: Materialii ~ 1Where:Actual Process Stream Ef, ~ actual organic HAP emissions factor for process stream i, Ibs/tonMaterial; ~ neat resin plus used during the last 12 calendar months for process stream i, tonsn ~ number of process streams where Boeing calculated an organic HAP emissions factor[40 CFR 63.58 1 0(a)(2)]Boeing may, but is not required to, include process streams where Boeing hasdemonstrated compliance as described in 40 CFR 63.5810(a), subject to the limitationsdescribed in 63.5810(a)(2), and Boeing is not required to and should not include processstreams for which Boeing will demonstrate compliance using the procedures in63.5810(d). [40 CFR 63.5810(b)(1)(ii), 8/25/05]Compare each organic HAP emissions factor calculated above with its correspondingorganic HAP emission limits in Table 3 or 5 to Subpart WWWW. If all emissions factorsare equal to or less than their corresponding emission limits, then compliance is achieved.[40 CFR 63.5810(b)(2), 8/25/05]Boeing-Everett Permit, issued September 12, 2008,' Administralive Amendment 3: October 10, 2012
