1. E. The monthly volume-weighted

average VOC content of all coatings used in a surface coating unit, expressed as pounds of VOC per gallon of coating (minus water and exempt compounds), shall be calculated using Equation (9) as follows:

n å (Ai × Bi) i=1 (9) = MAVGVW C Where: MAVGVW = monthly volume-weighted average VOC content as-applied, expressed as pounds of VOC per gallon of coating (minus water and exempt compounds); A = monthly gallons of each coating used (minus water and exempt compounds) in a surface coating unit; B = VOC content of the coating as-applied, expressed as pounds of VOC per gallon of coating (minus water and exempt compounds), as delivered to the coating applicator. This is determined by subparagraph (5)(C)1.A. of this rule; C = total monthly gallons of coatings used (minus water and exempt compounds) in a surface coating unit; and n = number of coatings used in a surface coating unit.

1. 4. The required control system efficien-

cy shall be determined using Equation (10) as follows:

(DAVG − LS)

R = VWS ×100 (10) DAVGVWS Where: R = required control system efficiency; DAVGVWS = daily volume-weighted average VOC content of all coatings used in a surface coating unit, expressed as pounds of VOC per gallon of coating solids, per subparagraph (5)(C)3.B. of this rule; and LS = emission limits expressed as pounds of VOC per gallon of coating solids, per paragraph (5)(C)2. of this rule.
