NR 440.72(4)(b)2.b.b. Where the volume-weighted average mass of VOCs emitted to the atmosphere per unit volume of coating solids applied (N) is less than or equal to 1.5 kilograms per liter for prime coats, is less than or equal to 1.5 kilograms per liter for color coats, is less than or equal to 2.3 kilograms per liter for texture coats, and is less than or equal to 2.3 kilograms per liter for touch-up coats, the affected facility is in compliance.
NR 440.72(4)(b)2.c.c. If each individual coating used by an affected facility has a VOC content (kg VOC/l of solids), as received, which when divided by the lowest transfer efficiency at which the coating is applied for each coating operation results in a value equal to or less than 1.5 kilograms per liter for prime and color coats and equal to or less than 2.3 kilograms per liter for texture and touch-up coats, the affected facility is in compliance provided that no VOCs are added to the coatings during distribution or application.
NR 440.72(4)(b)2.d.d. If an affected facility uses add-on controls to control VOC emissions and if the owner or operator can demonstrate to the administrator that the volume-weighted average mass of VOCs emitted to the atmosphere during each nominal 1-month period per unit volume of coating solids applied (N) is within each of the applicable limits expressed in subd. 2. b. because of this equipment, the affected facility is in compliance. In such cases, compliance will be determined by the administrator on a case-by-case basis.

NR 440.72(5)(a)1.1. Except as provided for in subd. 2., the volume-weighted average mass of VOCs emitted to the atmosphere per volume of applied coating solids (N) for the initial nominal 1-month period for each coating operation from each affected facility.
NR 440.72(5)(a)2.2. For each affected facility where compliance is determined under the provisions of sub. (4) (b) 2. c., a list of the coatings used during the initial nominal 1-month period, the VOC content of each coating calculated from data determined using Method 24, of Appendix A, 40 CFR part 60, incorporated by reference in s. NR 440.17 (1), and the lowest transfer efficiency at which each coating is applied during the initial nominal 1-month period.
NR 440.72(5)(b)(b) Following the initial report, each owner or operator shall:
NR 440.72(5)(b)1.1. Report the volume-weighted average mass of VOCs per unit volume of coating solids applied for each coating operation for each affected facility during each nominal 1-month period in which the facility is not in compliance with the applicable emission limits specified in sub. (3). Reports of noncompliance shall be submitted on a quarterly basis, occurring every 3 months following the initial report; and
NR 440.72(5)(b)2.2. Submit statements that each affected facility has been in compliance with the applicable emission limits specified in sub. (3) during each nominal 1-month period. Statements of compliance shall be submitted on a semiannual basis.
NR 440.72(5)(c)(c) These reports shall be postmarked not later than 10 days after the end of the periods specified in par. (b).
NR 440.72(5)(d)(d) Each owner or operator subject to the provisions of this section shall maintain at the source, for a period of at least 2 years, records of all data and calculations used to determine monthly VOC emissions from each coating operation for each affected facility as specified in s. NR 440.07 (5).
NR 440.72(5)(e)(e) Reporting and recordkeeping requirements for facilities using add-on controls will be determined by the administrator on a case-by-case basis.
NR 440.72(6)(6)Test methods and procedures.
NR 440.72(6)(a)(a) The reference methods in Appendix A, of 40 CFR part 60, incorporated by reference in s. NR 440.17, except as provided under s. NR 440.08 (2), shall be used to determine compliance with sub. (3) as follows:
NR 440.72(6)(a)1.1. Method 24 for determination of VOC content of each coating as received.
NR 440.72(6)(a)2.2. For Method 24, the sample shall be at least a 1-liter sample in a 1-liter container.
NR 440.72(6)(b)(b) Other methods may be used to determine the VOC content of each coating if approved by the administrator before testing.

NR 440.73(1)(1)Applicability and designation of affected facility.
NR 440.73(1)(a)(a) The affected facility to which this section applies is each calciner and dryer at a mineral processing plant. Feed and product conveyors are not considered part of the affected facility. For the brick and related clay products industry, only the calcining and drying of raw materials prior to firing of the brick are covered.

Also, the following processes and process units used at mineral processing plants are not subject to this section: vertical shaft kilns in the magnesium compounds industry; the chlorination oxidation process in the titanium dioxide industry; coating kilns, mixers and aerators in the roofing granules industry; and tunnel kilns, tunnel dryers, apron dryers, and grinding equipment that also dries the process material used in any of the 17 mineral industries as defined in sub. (2) (e).
NR 440.73(1)(c)(c) The owner or operator of any facility under par. (a) that commences construction, modification or reconstruction after April 23, 1986, is subject to this section.
