NR 469.04 Note Note: Unlike most of the control techniques available for complying with this rule, carbon adsorbers are not considered to be a pollution prevention measure. Use of such units may impose additional cost and burden for a number of reasons. First, carbon adsorption units are generally more expensive than other controls listed in the options. Second, these units may present cross-media impacts such as effluent discharges if not properly operated and maintained, and spent carbon beds have to be disposed of as hazardous waste. When making decisions about what controls to install on halogenated solvent cleaning machines to meet the requirements of this rule, all of these factors should be weighed and pollution prevention measures are encouraged wherever possible.

NR 469.04(2)(a)2. 2. Demonstrate that the solvent cleaning machine can achieve and maintain an idling emission limit of 0.22 kilograms per hour per square meter (0.045 pounds per hour per square foot) of solvent/air interface area as determined using the procedures in s. NR 469.09 (1).

NR 469.04 Note Note: Owners and operators who choose to comply with an idling emission limit should also refer to s. NR 469.07.

NR 469.04(2)(b) (b) Each owner or operator of a batch vapor cleaning machine with a solvent/air interface area greater than 1.21 square meters (13 square feet) shall comply with the requirements specified in either subd. 1. or 2.

NR 469.04(2)(b)1. 1. Employ one of the control combinations listed in Table 2 or other equivalent methods of control determined using the procedures in sub. (4).
