The exemption justification document for an emission unit or group of similar emission units must be made available for review during normal business hours and for state or EPA on-site inspections and shall be provided to the director or the director's representative upon request. If an exemption justification document does not exist, the applicability of the small unit exemption is voided for that particular emission unit or group of similar emission units. The controls described in the exemption justification document establish a limit on the potential emissions. An exemption justification document shall include the following for each applicable emission unit or group of similar emission units: 1. A narrative description of how the emissions from the emission unit or group of similar emission units were determined and maintained at or below the annual small unit exemption levels.2. If air pollution control equipment is used, a description of the air pollution control equipment used on the emission unit or group of similar emission units and a statement that the emission unit or group of similar emission units will not be operated without the pollution control equipment operating.3. If air pollution control equipment is used, the applicant shall maintain a copy of any report of manufacturer's testing results of any emissions test, if available. The department may require a test if it believes that a test is necessary for the exemption claim.4. A description of all production limits required for the emission unit or group of similar emission units to comply with the exemption levels.5. Detailed calculations of emissions reflecting the use of any air pollution control devices or production or throughput limitations, or both, for applicable emission unit or group of similar emission units.6. Records of actual operation that demonstrate that the annual emissions from the emission unit or group of similar emission units were maintained below the exemption levels.7. Facilities designated as major sources with respect to 567-22.4 (455B) and 567-24.101(455B), or subject to any applicable federal requirements, shall retain all records demonstrating compliance with the exemption justification document for five years. The record retention requirements supersede any retention conditions of an individual exemption.8. A certification from the responsible official that the emission unit or group of similar emission units have complied with the exemption levels specified in 22.1(2)"w"(1). (4) Requirement to apply for a construction permit. An owner or operator of a small unit will be required to obtain a construction permit or take the unit out of service if the emission unit exceeds the small unit emission levels. 1. If, during an inspection or other investigation of a facility, the department believes that the emission unit exceeds the emission levels that define a "small unit," then the department will submit calculations and detailed information in a letter to the owner or operator. The owner or operator shall have 60 days to respond with detailed calculations and information to substantiate a claim that the small unit does not exceed the emission levels that define a small unit.2. If the owner or operator is unable to substantiate a claim to the satisfaction of the department, then the owner or operator that has been using the small unit exemption must cease operation of that small unit or apply for a construction permit for that unit within 90 days after receiving a letter of notice from the department. The emission unit and control equipment may continue operation during this period and the associated initial application review period.3. If the notification of nonqualification as a small unit is made by the department following the process described above, the owner or operator will be deemed to have constructed an emission unit without the required permit and may be subject to applicable penalties.(5) Required notice for construction or modification of a substantial small unit. The owner or operator shall notify the department in writing at least ten days prior to commencing construction of any new or modified "substantial small unit" as defined in 22.1(2)"w"(6).

Notification shall include the name of the business, the location where the unit will be installed, and information describing the unit and quantifying its emissions. The owner or operator shall notify the department within 90 days of the end of the calendar year for which the aggregate emissions from substantial small units at the facility have reached any of the cumulative notice thresholds listed below.(6) For the purposes of this paragraph, "substantial small unit" means a small unit that emits more than the following amounts, as documented in the exemption justification document: 1. 2 pounds per year of lead and lead compounds expressed as lead (30 pounds per year of lead or lead compounds for equipment for which initiation of construction, installation, reconstruction, or alteration (as defined in 567-22.1 (455B)) occurred on or before October 23, 2013);2. 3.75 tons per year of sulfur dioxide;3. 3.75 tons per year of nitrogen oxides;4. 3.75 tons per year of volatile organic compounds;5. 3.75 tons per year of carbon monoxide;6. 3.75 tons per year of particulate matter (particulate matter as defined in 40 CFR 51.100(pp), as amended through November 7, 1986);7. 1.875 tons per year of PM10;8. 0.4 tons per year of PM2.5 (does not apply to equipment for which initiation of construction, installation, reconstruction, or alteration (as defined in 567-22.1 (455B)) occurred on or before October 23, 2013); or9. 3.75 tons per year of any hazardous air pollutant or 3.75 tons per year of any combination of hazardous air pollutants. An emission unit is a "substantial small unit" only for those substances for which annual emissions exceed the above-indicated amounts.
(7) Required notice that a cumulative notice threshold has been reached. Once a "cumulative notice threshold," as defined in 22.1(2)"w"(8), has been reached for any of the listed pollutants, the owner or operator at the facility must apply for air construction permits for all substantial small units for which the cumulative notice threshold for the pollutant(s) in question has been reached. The owner or operator shall have 90 days from the date it determines that the cumulative notice threshold has been reached in which to apply for construction permit(s). The owner or operator shall submit a letter to the department, within five working days of making this determination, establishing the date the owner or operator determined that the cumulative notice threshold had been reached.(8) "Cumulative notice threshold" means the total combined emissions from all substantial small units using the small unit exemption that emit at the facility the following amounts, as documented in the exemption justification document: 1. 0.6 tons per year of lead and lead compounds expressed as lead;2. 40 tons per year of sulfur dioxide;3. 40 tons per year of nitrogen oxides;4. 40 tons per year of volatile organic compounds;5. 100 tons per year of carbon monoxide;6. 25 tons per year of particulate matter (particulate matter as defined in 40 CFR 51.100(pp), as amended through November 7, 1986);7. 15 tons per year of PM10;8. 10 tons per year of PM2.5 (does not apply to equipment for which initiation of construction, installation, reconstruction, or alteration (as defined in 567-22.1 (455B)) occurred on or before October 23, 2013); or9. 10 tons per year of any hazardous air pollutant or 25 tons per year of any combination of hazardous air pollutants.x.
