(d) For each coating line, compliance with the emission limits specified in table 64-a, table 64-b, and table 64-d is based upon all of the following provisions:

(i) For prime coat operations that utilize an electrodeposition process in automobile and light-duty truck coating lines that are regulated under table 64-a, compliance is based on all coatings that belong to the same coating category that is used during each calendar month averaging period. For all other coatings, compliance is based on the volume-weighted average of all coatings that belong to the same coating category and are used during each calendar day averaging period. Under R 336.1602(2), the department may specifically authorize compliance to be based on a longer averaging period, not to exceed more than 1 calendar month.

(ii) If coatings that belong to more than 1 coating category are used on the same coating line during the specified averaging period, then compliance is determined separately for each coating category.

(iii) The information and records as required by subrule (5) of this rule.

(e) Compliance with the emission limits specified in this rule must be determined using the applicable method described in the following paragraphs:

(i) For the prime-electrodeposition process emission limit specified in table 64-a, the method described in either R 336.2040(12)(a) if the coating line does not have an add-on emissions control device or R 336.2040(12)(b) if the coating line has 1 or more add-on emissions control devices.

(ii) For the primer surfacer, topcoat, and combined primer surfacer and topcoat coating category emission limits specified in table 64-a, compliance must be determined by the methodology described in the publication entitled "Protocol for Determining the Daily Volatile Organic Compound Emission Rate of Automobile and Light-duty Truck Topcoat Operations," EPA-453/R-08-002, adopted by reference in R 336.1902. References to topcoat operations in this publication also apply to primer surfacer lines, with the following added provisions:

(A) Unless specifically included in the adopted publication, if an anti-chip, color-in-prime, blackout, or spot primer coating is applied as part of either a primer surfacer or topcoat coating operation, then the anti-chip, color-in-prime, blackout, or spot primer coating is included in the transfer efficiency tests for that coating operation, conducted according to section 18 or 19 of the adopted publication, and the transfer efficiency values in section 20 of the adopted publication must not be used.

(B) When spot primer is applied as part of a primer surfacer coating operation, then the daily usage of spot primer, as calculated in section 8 of the adopted publication, may be derived from monthly usage of spot primer based upon the number of vehicles processed in the primer surfacer operation each day. If an add-on emissions control device is used on the coating line application area to achieve compliance with the primer surfacer or topcoat emission limits specified in table 64-a, then the capture efficiency must be determined in accordance with R 336.2040(10).

(iii) For the final repair coating category emission limit specified in table 64-a, compliance must be on an occurrence weighted average basis, calculated in accordance with the following equation, in which clear coatings have a weighting factor of 2 and all other coatings have a weighting factor of 1:
