Applicability. This chapter applies to all surface coating and printing process air contaminant sources and to their owners and operators. This chapter also applies to the handling and use of cutback asphalts for application to surfaces traversed by motor vehicles, bicycles or pedestrians and to all persons responsible for such handling and use.
NR 422.01(2)
(2) Purpose. This chapter is adopted under ss.
285.11,
285.13 and
285.17, Stats., to categorize organic compound emissions from surface coating, printing and asphalt surfacing operations into separate organic compound air contaminant source categories and to establish emission limitations or other requirements for these categories of sources in order to protect air quality.
NR 422.01(3)
(3)
For a source located in an area that was ever designated nonattainment for ozone that had VOC emissions exceeding the applicability emission thresholds and became subject to the requirements of this chapter, the requirements of this chapter remain applicable notwithstanding any subsequent decrease in VOC emissions to a level below the applicability emission thresholds.
NR 422.01(4)
(4) The department may exempt a source from the requirements of this chapter if the source has an approved federally enforceable permit or state implementation plan revision that permanently restricts maximum theoretical emissions to below the applicability emission thresholds listed under this chapter and meets all applicable federal VOC RACT exemption requirements.
NR 422.01 Note
Note:
“Maximum theoretical emissions” referred to in this chapter is defined under s.
NR 419.02 (11).
