cAs per sub. (1) (b), any new coating operation with solvent utilization <38 m3/yr or any modified or reconstructed coating operation with solvent utilization <370 m3/yr is exempt from the VOC standards (sub. (3)). Such coating operations are subject only to subs. (5) (a) and (8) (b) and (c). However, should a coating operation once exceed the applicable annual solvent utilization cutoff, that coating operation shall be subject to the VOC standards (sub. (3)) and all other applicable subsections. Once this has occurred, the coating operation shall remain subject to those requirements regardless of changes in annual solvent utilization.

e40 CFR 60.716 permits the use of an alternative means of VOC emission limitation that achieves an equivalent or greater VOC emission reduction.

a Sub. (4) (a) specifies the procedures to be used prior to modification/reconstruction to establish the applicability of the VOC standards in sub. (3) (c) for modified/reconstructed coating operations. Subsection (4) (a) 1. requires the use of the procedures of sub. (4) (b) 1., 2., 3. or 4., to demonstrate prior to modification/reconstruction that 90% of the applied VOC is recovered or destroyed. Sub. (4) (a) 2. requires the use of procedures of sub. (4) (b) 5. to demonstrate prior to modification/reconstruction that the coating operation has a total enclosure vented to a control device that is at least 92% efficient. Sub. (4) (k) and (L) do not have corresponding test methods, monitoring, reporting or recordkeeping requirements.

b TI denotes thermal incinerator, CI denotes catalytic incinerator; CA denotes carbon adsorber; CO denotes condenser; PE denotes partial enclosure; TE denotes total enclosure.

c See sub. (8) (f) for additional reporting requirements when coating mix preparation equipment is constructed at a time when no coating operation is being constructed. See sub. (8) (g) for addition reporting requirements when coating mix preparation equipment is constructed at the same time as an affected coating operation.

NR 440.71(3)(a)(a) Each owner or operator of any affected facility that is subject to the requirements of this section shall comply with the emission limitations in this subsection on and after the date on which the initial performance test required by s. NR 440.08 is completed, but not later than 60 days after achieving the maximum production rate at which the affected facility will be operated or 180 days after initial startup, whichever date comes first.

NR 440.71(3)(b)(b) Each owner or operator shall control emissions from a new coating operation by recovering or destroying at least 93% of the VOC content of the coating applied at the coating applicator.

NR 440.71(3)(c)(c) Each owner or operator of a modified or reconstructed coating operation shall meet the appropriate standard in subds. 1. to 3., 4. or par. (d).

NR 440.71(3)(c)1.1. For coating operations demonstrated prior to modification or reconstruction pursuant to sub. (4) (a) 1. to have emissions controlled by the recovery or destruction of at least 90% of the VOC content of the coating applied at the coating applicator.

NR 440.71(3)(c)2.2. Subject to the provisions of subd. 3., each owner or operator shall continue to control emissions from the coating operation to at least the demonstrated level or 93%, whichever is lower.

NR 440.71(3)(c)3.3. If the VOC control device in use during the emission reduction demonstration made pursuant to sub. (4) (a) 1. is subsequently replaced, each owner or operator shall:

NR 440.71(3)(c)4.4. For coating operations demonstrated prior to modification or reconstruction pursuant to sub. (4) (a) 2. to have a total enclosure installed around the coating operation and all VOC emissions ventilated to a control device that is at least 92% efficient.

NR 440.71(3)(c)4.a.a. Subject to the provisions of subd. 4. b., each owner or operator shall continue to ventilate all VOC emissions from the total enclosure to the control device and maintain control device efficiency at or above the demonstrated level or 95%, whichever is lower.

NR 440.71(3)(c)4.b.b. If the VOC control device in use during the control device efficiency demonstration made pursuant to sub. (4) (a) 2. is subsequently replaced, each owner or operator shall install a VOC control device that is at least 95% efficient and ventilate all VOC emissions from the total enclosure to the control device.

NR 440.71(3)(d)(d) For coating operations not subject to par. (c) 1. to 4., each owner or operator shall control emissions from the coating operation by recovering or destroying at least 93% of the VOC content of the coating applied at the coating applicator.

NR 440.71(3)(e)(e) Each owner or operator constructing new coating mix preparation equipment with concurrent construction of a new VOC control device, other than a condenser, on a magnetic tape coating operation shall control emissions from the coating mix preparation equipment by installing and using a cover on each piece of equipment and venting the equipment to a 95% efficient control device. Each cover shall meet the following specifications:

NR 440.71(3)(e)1.1. Cover shall be closed at all times except when adding ingredients, withdrawing samples, transferring the contents or making visual inspection when such activities cannot be carried out with cover in place. Such activities shall be carried out through ports of the minimum practical size.

NR 440.71(3)(e)4.4. Any breach in the cover, such as an opening for insertion of a mixer shaft or port for addition of ingredients, shall be covered consistent with par. (c) 2. and 3., when not actively in use. An opening sufficient to allow safe clearance for a mixer shaft is acceptable during those periods when the shaft is in place; and

NR 440.71(3)(e)5.5. A polyethylene or nonpermanent cover may be used provided it meets the requirements of par. (c) 2. to 4. A cover may not be reused after once being removed.

NR 440.71(3)(f)(f) Each owner or operator of affected coating mix preparation equipment not subject to par. (e) shall control emissions from the coating mix preparation equipment by either:

NR 440.71(3)(f)1.1. Installing and using a cover that meets the specifications in par. (c) 1. to 5. and venting VOC emissions from the equipment to a VOC control device; or
