NR 438.03(1)(a)(a) Except as provided under par. (am), any person owning or operating a facility that emits an air contaminant in quantities above applicable reporting levels, except indirect sources of air pollution, shall annually submit to the department an emissions inventory of annual, actual emissions or, for primary particulate matter, primary PM10, primary PM2.5, sulfur dioxide, nitrogen oxides, carbon monoxide and volatile organic compounds, throughput information sufficient for the department to calculate its annual, actual emissions. The reportable air contaminants and applicable reporting levels are listed in Table 1 in this chapter. NR 438.03(1)(af)(af) The owner or operator of a facility shall annually submit to the department an emissions inventory for sulfur dioxide, nitrogen oxides, carbon monoxide, volatile organic compounds, primary PM10, primary PM2.5, ammonia, and lead and lead compounds, if the facility meets any of the following: NR 438.03(1)(af)3.3. The facility has the potential to emit equal to or greater than 100 tons per year of ammonia. NR 438.03(1)(af)4.4. The facility has actual emissions equal to or greater than 0.5 ton per year of lead. NR 438.03(1)(am)1.1. The owner or operator of a facility described by an SIC code listed in Table D of s. NR 445.11, or that has annual actual emissions of less than 5 tons of particulate matter and less than 3 tons of volatile organic compounds, may limit the information on hazardous air contaminants included in the annual emissions inventory to those contaminants identified under s. NR 445.11 (1) (a) or (b). NR 438.03(1)(am)2.2. Notwithstanding subd. 1., the owner or operator shall continue to report annual emissions of any air contaminant reported in prior calendar years for the facility, provided annual, actual emissions are greater than the reporting level in Table 1. NR 438.03(1)(am)3.3. The owner or operator of a facility may exclude emissions from any of the following emissions units, operations, or activities from the annual emissions inventory: NR 438.03(1)(am)3.a.a. Maintenance of grounds, equipment, and buildings, including lawn care, pest control, grinding, cutting, welding, painting, woodworking, general repairs, and cleaning, but not including use of organic compounds as clean-up solvents.
