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.

NR 438.03(1)(b)(b) When preparing an emissions inventory, the owner or operator of a facility may rely on information in an approved safety data sheet. Trace contaminants need not be reported if they constitute less than 1 percent (10,000 parts per million) of the material, or 0.1 percent (1,000 parts per million) of the material if the air contaminant is listed with a control requirement under column (i) of Table A, B or C of s. NR 445.07, unless a hazardous air contaminant is formed in processing the material. NR 438.03(1)(c)(c) Notwithstanding par. (a), the department may require any facility to submit an emissions inventory of its annual, actual and maximum theoretical air contaminant emissions. NR 438.03(1)(d)(d) Any facility that generates or holds emission reduction credits shall report the credits separately to the annual emissions inventory. NR 438.03(2)(2) Reporting deadline. Emissions inventories required under this section shall be submitted by March 1 of each year for air contaminants emitted during the preceding year. Through March 1, persons may be granted a 2-week submittal extension ending on March 15, when requested by email, mail, or other manner prescribed, provided the extension is considered reasonable under the circumstances by the department. NR 438.03(3)(3) Portable sources. The owner or operator of a portable source shall file an emissions inventory covering all operations at all locations in the state during the previous year. NR 438.03(4)(4) Required records. An owner or operator of a facility required to file an emissions inventory shall keep accurate and reliable records sufficient to enable verification of the emissions inventory by the department. Records shall include data on fuel composition and consumption, composition and quantities of raw materials handled that contribute to emissions, composition and quantities of wastes incinerated, continuous emissions monitoring data and audits, and any results of stack or performance tests together with the names of persons or firms responsible for each test, if applicable. Records shall be retained for 5 years following the year in which the emissions inventory is submitted. NR 438.03(5)(a)(a) Based on the throughput or emissions information submitted under this section and s. NR 438.04, the department shall determine each facility’s annual actual emissions and typical ozone season day emissions based on emission factors contained in Compilation of Air Pollutant Emission Factors, AP-42, Volume 1: Stationary Point and Area Sources, USEPA-OAQPS, as incorporated by reference under s. NR 484.05 (8), or in the EPA’s online database of emissions factors for criteria and hazardous air pollutants. Other emission factors or methods, including mass balance or other use reporting, consumption and analytical methodologies, or continuous emissions monitoring data, if applicable, may be used by the department. NR 438.03 NoteNote: The EPA’s WebFIRE database of emissions factors for criteria and hazardous air pollutants is available at https://cfpub.epa.gov/webfire/. NR 438.03(5)(b)(b) The actual annual emissions determined by the department under par. (a) shall constitute the department’s annual emissions inventory. NR 438.03(5)(c)(c) By May 31 of each year, the department shall send each owner or operator of a facility that is required to file an emissions inventory a notification that an emissions inventory summary report of the air contaminants emitted by the facility for the previous year has been created by the department. The owner or operator of a facility required to obtain an air pollution control permit under s. 285.60, Stats., and ch. NR 405, 406, 407, or 408, or that emits volatile organic compounds or nitrogen oxides in an ozone nonattainment area, shall, by June 30 of each year, send a written certification to the department that its emissions inventory summary report is correct. The certification shall contain the name, title, signature, and telephone number of the responsible official, the date of certification, and a statement that the information contained in the emissions inventory summary report is accurate to the best knowledge of the owner or operator of that facility. NR 438.03(6)(6) Disputed emissions. Any facility that disputes the emissions inventory summary report created by the department under sub. (5) (c) may request, in writing, that the department review its emissions inventory summary report. The department shall review and supply to the facility, within 14 calendar days of receipt of the facility’s written request, information used to prepare the emissions inventory summary report for that facility. If the facility continues to dispute the emissions inventory summary report, it shall supply to the department, within 14 calendar days of receipt of the department’s information, the reasons it disputes the report. The facility shall be notified within 7 calendar days of receipt of this information of the department’s decision on whether to adjust the emissions inventory and recreate the emissions inventory summary report. If the facility continues to dispute the emissions inventory summary report, it may appeal the department’s final decision pursuant to state law. The responsible official for the facility shall certify any emissions not in dispute by June 30 of each year. NR 438.03 HistoryHistory: Cr. Register, May, 1993, No. 449, eff. 6-1-93; am.
