G. CALCULATING EMISSIONS1. Calculating Volatile Organic Compounds Regulatory Content (VOC Regulatory):G1 =Wv – Ww – WecVm – Vw – VecWhere G1 = Regulatory Content, Weight of volatile organic compound per totalvolume of coating, less water and exempt compounds, in grams per literWv = Weight of volatile compounds including any volatile materials added tothe original coating supplied by the manufacturer, in gramsWw = Weight of water, in gramsWec = Weight of exempt compounds as defined in Rule 459 Section 229, ingramsVm = Volume of coating material, in litersVw = Volume of water, in litersVec = volume of exempt compounds as defined in Rule 459 Section 229, inliters2. Calculating Volatile Organic Compounds Actual Content (VOC Actual) of a coating:G2 =Wv – Ww – WecVmWhere G2 = Actual Content, Weight of volatile organic compound per total volume ofcoating, in grams per literWv = Weight of volatile compounds including any volatile materials added tothe original coating supplied by the manufacturer, in gramsWw = Weight of water, in gramsWec = Weight of exempt compounds as defined in Rule 459 Section 229, ingramsVm = Volume of coating material, in liters3. Calculating Volatile Organic Compounds Actual Content (VOC Actual) of coating removers andsolvents:G3 =Wv – Ww – WecVmWhere G3 = Actual Content, Weight of volatile organic compound per total volume ofmaterial, in grams per literWv = Weight of volatile compounds, in gramsWw = Weight of water, in gramsWec = Weight of exempt compounds as defined in Rule 459 Section 229, ingramsVm = Volume of material, in litersDetermining ROC emissions for quarterly and annual complianceTotal ROC Emissions (lb/qtr) = [Coating Usage (gal/qtr)]*[VOC Actual (G2) (lb/gal)] +[Coating Remover and Solvent Usage (gal/qtr)]*[VOCActual Content (G3) (lb/gal)]4.
