NR 440.58(7)(a)1.1. Method 24, or data provided by the formulator of the coating, shall be used for determining the VOC content of each coating as applied to the surface of the metal coil. In the event of a dispute, Method 24 shall be the reference method. When VOC content of waterborne coatings, determined by Method 24, is used to determine compliance of affected facilities, the results of the Method 24 analysis shall be adjusted as described in section 12.6 of Method 24. NR 440.58(7)(a)2.2. Method 25, both for measuring the VOC concentration in each gas stream entering and leaving the control device on each stack equipped with an emission control device and for measuring the VOC concentration in each gas stream emitted directly to the atmosphere. NR 440.58(7)(b)(b) For Method 24 of 40 CFR part 60, Appendix A, incorporated by reference in s. NR 440.17, the coating sample shall be at least a one-liter sample taken at a point where the sample will be representative of the coating as applied to the surface of the metal coil. NR 440.58(7)(c)(c) For Method 25 of 40 CFR part 60, Appendix A, incorporated by reference in s. NR 440.17 (1), the sampling time shall be at least 60 minutes, and the minimum sample volume shall be at least 0.003 dscm (0.11 dscf); however, shorter sampling times or smaller volumes, when necessitated by process variables or other factors, may be approved by the department. NR 440.58(7)(d)(d) The department shall approve testing of representative stacks on a case-by-case basis if the owner or operator can demonstrate to the satisfaction of the department that testing of representative stacks yields results comparable to those that would be obtained by testing all stacks.

NR 440.59(1)(1) Applicability and designation of affected facilities. NR 440.59(1)(a)(a) The affected facilities to which this section applies are each saturator and each mineral handling and storage facility at asphalt roofing plants; and each asphalt storage tank and each blowing still at asphalt processing plants, petroleum refineries and asphalt roofing plants. NR 440.59(1)(b)(b) Any saturator or mineral handling and storage facility under par. (a) that commences construction or modification after November 18, 1980 is subject to the requirements of this section. Any asphalt storage tank or blowing still that processes or stores, or both processes and stores, asphalt used for roofing only or for roofing and other purposes, and that commences construction or modification after November 18, 1980 is subject to the requirements of this section. Any asphalt storage tank or blowing still that processes or stores, or both processes and stores, only nonroofing asphalts and that commences construction or modification after May 26, 1981 is subject to the requirements of this section. NR 440.59(2)(2) Definitions. As used in this section, terms not defined in this subsection have the meanings given in s. NR 440.02. NR 440.59(2)(a)(a) “Afterburner” or “A/B” means an exhaust gas incinerator used to control emissions of particulate matter. NR 440.59(2)(b)(b) “Asphalt processing” means the storage and blowing of asphalt. NR 440.59(2)(c)(c) “Asphalt processing plant” means a plant which blows asphalt for use in the manufacture of asphalt products. NR 440.59(2)(d)(d) “Asphalt roofing plant” means a plant which produces asphalt roofing products (shingles, roll roofing, siding or saturated felt). NR 440.59(2)(e)(e) “Asphalt storage tank” means any tank used to store asphalt at asphalt roofing plants, petroleum refineries and asphalt processing plants. Storage tanks containing cutback asphalts (asphalts diluted with solvents to reduce viscosity for low temperature applications) and emulsified asphalts (asphalts dispersed in water with an emulsifying agent) are not included. NR 440.59(2)(f)(f) “Blowing still” means the equipment in which air is blown through asphalt flux to change the softening point and penetration rate. NR 440.59(2)(g)(g) “Catalyst” means a substance which, when added to asphalt flux in a blowing still, alters the penetrating-softening point relationship or increases the rate of oxidation of the flux. NR 440.59(2)(h)(h) “Coating blow” means the process in which air is blown through hot asphalt flux to produce coating asphalt. The coating blow starts when the air is turned on and stops when the air is turned off. NR 440.59(2)(i)(i) “Electrostatic precipitator” or “ESP” means an air pollution control device in which solid or liquid particulates in a gas stream are charged as they pass through an electric field and precipitated on a collection surface. NR 440.59(2)(j)(j) “High velocity air filter” or “HVAF” means an air pollution control filtration device for the removal of sticky, oily or liquid aerosol particulate matter from exhaust gas streams. NR 440.59(2)(k)(k) “Mineral handling and storage facility” means the areas in asphalt roofing plants in which minerals are unloaded from a carrier, the conveyor transfer points between the carrier and the storage silos and the storage silos. NR 440.59(2)(L)(L) “Saturator” means the equipment in which asphalt is applied to felt to make asphalt roofing products. The term saturator includes the saturator, wet looper and coater.
