(d) The VOC composite partial vapor pressure of each cleaning solution shall be determined by any of the following methods:
1. If diluted prior to use, calculate the VOC composite vapor pressure of the as-applied solvent by using the formula for "VOC composite vapor pressure" as follows:
a. Determine the identity and quantity of each compound in a blended organic solvent.
b. Determine the vapor pressure of each pure VOC component.
c. Calculate the VOC composite partial pressure of the solvent by using the formula for "VOC composite partial pressure." For the purpose of this calculation, the blended solvent shall be assumed to be an ideal solution where "Raoult's Law" applies. The partial vapor pressures of each compound at 68ºF shall be used in the formula. The VOC composite partial pressure shall be calculated as follows: where:
Wi is the weight of the "i"th VOC compound, in grams.
Ww is the weight of water, in grams.
We is the weight of exempt compound, in grams.
MWi is the molecular weight of the "i"th VOC compound, in grams per gram-mole.
MWw is the molecular weight of water, in grams per gram-mole.
MWe is the molecular weight of the "e"th exempt compound, in grams per gram-mole.
PPc is the VOC composite vapor pressure at 68ºF, in mm Hg.
VPi is the vapor pressure of the "i"th VOC compound at 68ºF, in mm Hg.
2. If not diluted prior to use, the owner or operator shall use formulation information provided by the supplier, such as a safety data sheet (SDS) or equivalent information from the supplier as long as it is based on results determined in accordance with the procedure in sub. (7) (d) 1.
SECTION 22. NR 422.143 (8) (a) and (b) (title) are repealed.
SECTION 23. NR 422.143 (8) (b) 1. is renumbered NR 422.143 (8) (am), and amended to read:
NR 422.143 (8) (am) The owner or operator of a heatset web lithographic printing press which that is installed after May 1, 2010 the effective date of this rule [LRB inserts date] shall perform a compliance emission test within 180 days after installation of the press and shall submit to the department no later than 60 days after the test written certification that the press is in compliance with the applicable requirements of subs. sub. (3) and (6) and a demonstration of compliance in accordance with subs. (6), (7), and (8).
SECTION 24. NR 422.143 (8) (b) 2. is renumbered NR 422.143 (8) (bm), and amended to read:
NR 422.143 (8) (bm) The owner or operator of any lithographic printing press, other than a heatset web press, which that is installed after May 1, 2010 the effective date of this rule [LRB inserts date] shall submit to the department, no later than 180 days after installation of the press, written certification that the press is in compliance with the applicable requirements of subs. sub. (3) and (6) and a demonstration of compliance in accordance with subs. (6), (7), and (8).
SECTION 25. NR 422.143 (8) (c) is created to read:
NR 422.143 (8) (c) Facilities subject to this section and located in an area described under sub. (1) (a) 2. c., shall comply with the applicable requirements of this section by the following deadlines:
1. Facilities that were initially constructed in an area described in sub. (1) (a) 2. c., prior to the effective date of its designation as moderate, serious, severe, or extreme ozone nonattainment, shall comply with applicable requirements within 180 days of the effective date of designation.
2. Facilities that were initially constructed in an area described in sub. (1) (a) 2. c., after the area has been designated as moderate, serious, severe, or extreme ozone nonattainment, shall comply with applicable requirements upon startup.
SECTION 26. EFFECTIVE DATE. This rule shall take effect on the first day of the month following publication in the Wisconsin administrative register as provided in s. 227.22 (2) (intro.), Stats. SECTION 27. BOARD ADOPTION. This rule was approved and adopted by the State of Wisconsin Natural Resources Board on January 23, 2019.
