NR 415.06(3)(3)In addition to meeting the requirements of sub. (1) or (2), all installations located in or near an area identified in s. NR 415.035 (2) whose aggregate particulate emissions, excluding fugitive dust, may cause an impact on the ambient air quality in the areas equal to or greater than an annual concentration of one microgram per cubic meter or a maximum 24-hour concentration of 5 micrograms per cubic meter shall meet the following RACT emission limitations:
NR 415.06(3)(a)(a) Installations of 100 million Btu per hour or less: maximum emission from any stack of 0.24 pounds of particulate matter per million Btu heat input.
NR 415.06(3)(b)(b) Installations of more than 100 million Btu per hour on which construction or modification commenced on or before April 1, 1972: maximum emission from any stack of 0.15 pounds of particulate matter per million Btu heat input.
NR 415.06(3)(c)(c) Installations of more than 100 million Btu per hour but of not more than 250 million Btu on which construction or modification commenced after April 1, 1972: maximum emission from any stack of 0.15 pounds of particulate matter per million Btu heat input.
NR 415.06(3)(d)(d) Installations of more than 250 million Btu per hour on which construction or modification commenced after April 1, 1972: maximum emission from any stack of 0.10 pounds of particulate matter per million Btu heat input.
NR 415.06(4)(4)Notwithstanding sub. (3) (a) or (b), any fuel burning installation of 250 million Btu per hour or less on which construction or modification was commenced on or before April 1, 1972 may emit up to, but not more than, an emission rate defined by the equation

where I is the heat input in millions of Btu per hour and E is the maximum allowable particulate matter emissions from any stack in pounds per million Btu heat input, if the installation has an emission rate based on original design or equipment performance test conditions, whichever is more restrictive, which is less than the limit set by the above equation, and the emission control system of the installations has not been allowed to degrade more than 0.05 pound per million Btu heat input from original design or acceptance performance test conditions.
