Rule 621.
Where:
A = Allowable equivalent emission limit, pounds of volatile organic compounds per gallon of applied coating solids.
E = Applicable emission limit as specified in subrule (1) of this rule, pounds of volatile organic compounds per gallon of coating, minus water, as applied.
S = Solids volume fraction representative of a compliance coating, gallon of solids per gallon of coating, minus water, as applied.
The value of 's" must be determined by using the following equation:
(TE)b = Overall baseline transfer efficiency of the coating line as specified in subrule (4) of this rule, percent. If multiple application methods are used on the coating line, the overall baseline transfer efficiency must be determined using the method described in R 336.2040(9). Department approval of the transfer efficiency test method is required.
