This term includes, but is not limited to, substances which are toxic, corrosive, flammable, irritants, strong sensitizers or explosives as determined by the department.
“Lowest achievable emission rate" means the rate of emission which reflects the more stringent of the following:
The most stringent emission limitation which is contained in the air pollution regulatory program of any state for this class or category of source, unless an applicant for a permit demonstrates that these limitations are not achievable; or
The most stringent emission limitation which is achieved in practice by the class or category of source.

“Minor source" means a stationary source that is not a major source.
“Modification" means any physical change in, or change in the method of operation of, a stationary source that increases the amount of emissions of an air contaminant or that results in the emission of an air contaminant not previously emitted, subject to rules promulgated under s. 285.11 (17)
“Modified source" means a stationary source on which modification commences after November 15, 1992.
“Municipality" means any city, town, village, county, county utility district, town sanitary district, public inland lake protection and rehabilitation district or metropolitan sewage district.
“New source" means a stationary source on which construction, reconstruction or replacement commences after November 15, 1992.
“Nonattainment area" means an area identified by the department in a document prepared under s. 285.23 (2)
where the concentration in the atmosphere of an air contaminant exceeds an ambient air quality standard.
“Person" means an individual, owner, operator, corporation, limited liability company, partnership, association, municipality, interstate agency, state agency or federal agency.
“Reasonably available control technology" means that control technology which provides the lowest emission rate that a particular source is capable of achieving by the application of control technology that is reasonably available considering technological and economic feasibility.
“Refuse" means all matters produced from industrial or community life, subject to decomposition, not defined as sewage.
“Regulated pollutant" means any of the following, except for carbon monoxide:
A pollutant for which a national primary ambient air quality standard has been promulgated under 42 USC 7409
“Replenishment implementation period" means the period between August 1, 1987, and December 31 of the year by which the department requires full compliance with rules required to be promulgated under s. 285.39 (3)
“Secretary" means the secretary of natural resources.
“Sewage" means the water-carried wastes created in and to be conducted away from residences, industrial establishments, and public buildings as defined in s. 101.01 (12)
