Applicability. This chapter applies to all direct air contaminant sources which are located in the specific geographic areas described in this chapter and which emit sulfur dioxide or other sulfur compounds and to all owners and operators of these sources.
NR 418.01(2)
(2) Purpose. This chapter is adopted under
ss. 285.11,
