NR 440.71 NoteNote: Under 40 CFR 60.716, if, in the administrator’s judgment, an alternative means of emission limitation will achieve a reduction in emissions of VOC from any emission point subject to sub. (3) (e) or (f) (standards for mix equipment) at least equivalent to that required by sub. (3) (e) or (f), respectively, the administrator will publish in the Federal Register a notice permitting the use of the alternative means. The notice may condition permission on requirements related to the operation and maintenance of the alternative means. Any such notice shall be published only after public notice and an opportunity for a public hearing. Any person seeking permission under 40 CFR 60.716 shall submit either results from an emission test that documents the collection and measurement of all VOC emissions from a given control device or an engineering evaluation that documents the determination of such emissions.

The owner or operator shall also submit actual solvent use records at the end of the initial calendar year. NR 440.71(8)(c)(c) Each owner or operator of an affected coating operation initially utilizing less than the applicable volume of solvent specified in sub. (1) (b) per calendar year shall report the first calendar year in which actual annual solvent use exceeds the applicable volume. NR 440.71(8)(d)(d) Each owner or operator of an affected coating operation or affected coating mix preparation equipment subject to sub. (3) (e), shall submit semiannual reports to the department documenting the following: NR 440.71(8)(d)1.1.

(3) (g), liquid material balance; NR 440.71(8)(d)2.2. The VOC contained in the coatings for the manufacture of magnetic tape for any 1-month period during which the weighted average solvent content (G) of the coatings exceeded 0.20 kilogram per liter of coating solids for those affected facilities complying with sub.
