NR 425.01(1)(1) Applicability. This chapter applies to all air contaminant sources governed by chs. NR 419 to 424 and to their owners and operators.

NR 425.01(2)(2) Purpose. This chapter is adopted under ss. 285.11, 285.13 and 285.17, Stats., to establish time schedules for air contaminant sources governed by chs. NR 419 to 424 to meet the emission limits set for each specific organic compound emission source, to specify exceptions to the requirements of chs. NR 419 to 424, to establish an internal offset system and to establish criteria for granting compliance schedule delays.

NR 425.02(1)(1) “Energy intensive control device” means an air pollution control device or system which consumes energy at a rate in excess of what would be required to heat the exhaust gas stream from 70°F to 800°F, taking into account energy recovered in the form of heat or organic compounds.

NR 425.02(2)(2) “Hydrophobic substrate” means any substrate that is resistant to or avoids wetting. This may include but is not limited to polyethylene, polypropylene, cellophane, metalized polyester, nylon and polyester film.

NR 425.02 HistoryHistory: Renum. from NR 154.01, Register, September, 1986, No. 369, eff. 10-1-86; am. (intro.), Register, February, 1990, No. 410, eff. 3-1-90; am. (intro.) and (2), Register, October, 1999, No. 526, eff. 11-1-99.

NR 425.03(1)(1) Effective dates. Subsections (2) to (8) do not apply to a source which is in compliance with the emission limitations of chs. NR 419 to 424, provided the source has determined and certified compliance to the satisfaction of the department within 90 days after the date specified in the effective date table, nor do subs. (2) to (7) apply to a source on which construction or modification commenced on or after the specified date. Sources on which construction or modification commenced on or after the date specified in the effective date table shall meet the emission requirements of chs. NR 419 to 424 in accordance with the provisions of sub. (8).

NR 425.03(2)(2) Process and emission control equipment installations. Except as provided under sub. (5) and s. NR 425.04, the owner or operator of a VOC emission source proposing to install and operate VOC emission control equipment or replacement process equipment to comply with the emission limiting requirements of chs. NR 419 to 424 shall achieve final compliance within 26 months of the date specified in the effective date table for that source.

The effective date listed under the Date column applies to the requirements outlined in all sections listed in the Section column to the right of the effective date in this table.

NR 425.03(3)(3) Low solvent content coating or ink.

NR 425.03(3)(a)(a) Except as provided under pars. (b) to (e) and subs. (5) and (7m), the owner or operator of a VOC source proposing to employ low solvent content coating or ink application technology to comply with the requirements of chs. NR 419 to 424 shall achieve final compliance within 28 months of the date specified in the effective date table for that source.

NR 425.03(3)(b)(b) The owner or operator of a can coating or flexible packaging facility proposing to employ low solvent content coating technology to comply with the requirements of s. NR 422.05 (2) (d) or 422.07 (2) may exceed the deadline in par. (a) by 12 months in developing acceptable can end sealing compounds or coatings for hydrophobic flexible packaging substrates.
