Section Env-A 804.05 - Calculation of VOC Content of a Coating FormulationThe owner or operator of a VOC source subject to a pounds VOC per gallon of coating standard as specified in Env-A 1200, which uses a coating that contains more than one VOC component, shall calculate the VOC content of the coating using the following formula, provided no chemical reaction occurs during the formulation process:
(a) "Pounds per gallon of coating (P)" means the VOC content of the coating formulation, as applied, used on a coating line or operation in units of pounds (lb) of VOC per gallon (gal) of coating or kilograms (kg) of VOC per liter (l) of coating, minus water and exempt VOC compounds;(b) "n" means the number of different coatings or diluents, as applied, used in the coating formulation;(c) "i" means the subscript denoting an individual coating or diluent;(d) "Vi" means the volume of the coating or diluent i, as applied, used in the coating formulation in units of gallons or liters, minus water and exempt VOC compounds;(e) "Ci" means the VOC content of the coating or diluent i, as applied, used in the coating formulation in units of lb of VOC/gal of coating, or kg of VOC/l of coating less water and exempt VOC compounds, as determined from the Method 24 or 24A analysis and the calculation procedures in Section 2.2 of EPA-340/1-86-016, A Guideline for Surface Coating Calculations, July, 1986;(f) "VT" means the total volume of the coating formulation, as applied, in units of gallons or liters, minus water and exempt VOC compounds; and(g) P shall be equal to the sum of the products of Vi and Ci for coatings or diluents one through n divided by VT , as in the following equation: Click here to view Image
