Section Env-A 1219.03 - Determining Compliance with Option 3(a) A facility choosing option 3 in Env-A 1219.02(c) for any of its operations shall determine a facility-specific monomer VOC mass emission limit, calculated on a consecutive 12-month period at the end of every month, by using the following formula: (1) "Monomer VOC Limit" means total allowable monomer VOC that can be emitted from the open molding operations included in the average, kilograms per 12-month period;(2) "MR" means mass of production resin used in the past 12 months, excluding any materials that are exempt, in megagrams; (3) "MPG" means the mass of pigmented gel coat used in the past 12 months, excluding any materials that are exempt, in megagrams; (4) "MCG" means the mass of clear gel coat used in the past 12 months, excluding any materials that are exempt, in megagrams; (5) "MTR" means the mass of tooling resin used in the past 12 months, excluding any materials that are exempt, in megagrams; (6) "MTG" means the mass of tooling gel coat used in the past 12 months, excluding any materials that are exempt, in megagrams; and (7) The monomer VOC limit shall equal the sum of the products of 46 times MR, 159 times MPG, 291 times MCG, 54 times MTR, and 214 times MTG, as in the following equation: Monomer VOC Limit = 46(MR) + 159(MPG) + 291(MCG) + 54(MTR) + 214(MTG)
(b) At the end of the first 12-month averaging period and at the end of every subsequent month, a facility choosing option 3 shall use the following equation to show that the monomer VOC emissions from the operations included in the average do not exceed the emission limit calculated using the equation in (a), above, for the same 12-month period: (1) "Monomer VOC emissions" means monomer VOC emissions calculated using the monomer VOC emission equations for each operation included in the average, in kilograms;(2) "PVR" means weighted-average monomer VOC emission rate for production resin used in the past 12 months, in kilograms per megagram;(3) "MR" means mass of production resin used in the past 12 months, in megagrams; (4) "PVPG" means weighted-average monomer VOC emission rate for pigmented gel coat used in the past 12 months, in kilograms per megagram;(5) "MPG" means mass of pigmented gel coat used in the past 12 months, in megagrams;(6) "PVCG" means weighted-average monomer VOC emission rate for clear gel coat used in the past 12 months, in kilograms per megagram; (7) "MCG" means mass of clear gel coat used in the past 12 months, in megagrams; (8) "PVTR" means weighted-average monomer VOC emission rate for tooling resin used in the past 12 months, in kilograms per megagram; (9) "MTR" means mass of tooling resin used in the past 12 months, in megagrams; (10) "PVTG" means weighted-average monomer VOC emission rate for tooling gel coat used in the past 12 months, in kilograms per megagram; (11) MTG" means mass of tooling gel coat used in the past 12 months, in megagrams; and (12) Monomer VOC emissions shall equal the sum of the products of PVR times MR, PVPG times MPG, PVCG times MCG, PVTR times MTR, and PVTG times MTG, as in the following equation: Monomer VOC emissions = (PVR)( MR) + (PVPG)( MPG) + (PVCG)( MCG) + (PVTR)( MTR) + (PVTG)( MTG)
(c) A facility choosing option 3 shall use the following equation to compute the weighted-average monomer VOC emission rate for the previous 12 consecutive months for each open molding resin and gel coat operation included in the average: (1) "PVOP" means the weighted-average monomer VOC emission rate for each open molding operation (PVR, PVPG, PVCG, PVTR, and PVTG) included in the average, in kilograms of monomer VOC per megagram of material applied; (2) "Mi" means the mass of resin or gel coat i used within an operation in the past 12 months, in megagrams; (3) "n" means the number of different open molding resins and gel coats used within an operation in the past 12 months; (4) "PVi" means the monomer VOC emission rate for resin or gel coat i used within an operation in the past 12 months, in kilograms of monomer VOC per megagram of material applied. Use the formulas in table 1219-2 to compute PVi; and (5) PVOP shall equal the sum of the products of Mi and PVi for open molding resin or gel coats one through n, divided by Mi one through n, as in the following equation: Click here to view image
