k is the total number of raw inks and related coatings measured as used in direct mass quantities with different amounts of water content

m is the total number of raw inks and related coatings measured as used by volume with different amounts of water content or different densities

n is the total number of raw inks and related coatings measured as used by volume with different amounts of water content or different water densities

k is the total number of VOC solvents, miscellaneous solventborne waste inks, and waste VOC solvents measured as recovered by volume with different densities

NR 440.56(4)(b)6.6. The average VOC emission percentage for the affected facility shall be determined by the following equation:

NR 440.56(4)(c)(c) If an affected facility controlled by a solvent recovery system uses only solventborne ink systems, the owner or operator may choose to determine compliance on a direct mass or a density-corrected liquid volume basis. Except as provided in pars. (d) through (g), compliance shall be determined as follows:

NR 440.56(4)(c)1.1. On a direct mass basis, compliance shall be determined according to par. (b), except that the water term Mv does not apply.

NR 440.56(4)(c)2.2. On a density-corrected liquid volume basis, compliance shall be determined by the following procedures:

NR 440.56(4)(c)2.a.a. A base temperature corresponding to that for the largest individual amount of VOC solvent used or recovered from the affected facility, or other reference temperature, shall be chosen by the owner or operator.

NR 440.56(4)(c)2.b.b. The corrected liquid volume of VOC in the raw inks and related coatings used shall be determined by the following equation:

k is the total number of raw inks and related coatings measured as used in direct mass quantities with different amounts of VOC content

m is the total number of raw inks and related coatings measured as used by volume with different amounts of VOC content or different densities

n is the total number of raw inks and related coatings measured as used by volume with different amounts of VOC content or different amounts of VOC content or different VOC solvent densities

NR 440.56(4)(c)2.c.c. The total corrected liquid volume of VOC used shall be determined by the following equation:

m and n are the respective total numbers of VOC dilution and cleaning solvents measured as used by volume with different densities

NR 440.56(4)(c)2.d.d. The total corrected liquid volume of VOC solvent recovered shall be determined by the following equation:

k is the total number of VOC solvents, miscellaneous solventborne waste inks, and waste VOC solvents measured as recovered by volume with different densities

NR 440.56(4)(c)2.e.e. The average VOC emission percentage for the affected facility shall be determined by the following equation:

NR 440.56(4)(d)(d) If 2 or more affected facilities are controlled by the same solvent recovery system, compliance shall be determined by the procedures specified in par. (b) or (c), whichever applies, except that (Lt)a and (Lr)a, (Mt)a, (Mr)a and (Mv)a are the collective amounts of VOC solvent and water corresponding to all the affected facilities controlled by that solvent recovery system. The average VOC emission percentage for each of the affected facilities controlled by that same solvent recovery system shall be assumed to be equal.

NR 440.56(4)(e)(e) Except as provided under par. (f), if an existing facility and an affected facility are controlled in common by the same solvent recovery system, the owner or operator shall determine compliance by conducting a separate emission test on the existing facility and then conducting a performance test on the combined facilities as follows:
