R307-415-5e. Permit Applications: Insignificant Activities and Emissions

  An application may not omit information needed to determine the applicability of, or to impose, any applicable requirement, or to evaluate the fee amount required under R307-415-9. The following lists apply only to operating permit applications and do not affect the applicability of R307-415 to a source, do not affect the requirement that a source receive an approval order under R307-401, and do not relieve a source of the responsibility to comply with any applicable requirement.

  (1) The following insignificant activities and emission levels are not required to be included in the permit application.

  (a) Exhaust systems for controlling steam and heat that do not contain combustion products, except for systems that are subject to an emission standard under any applicable requirement.

  (b) Air pollutants that are present in process water or non-contact cooling water as drawn from the environment or from municipal sources, or air pollutants that are present in compressed air or in ambient air, which may contain air pollution, used for combustion.

  (c) Air conditioning or ventilating systems not designed to remove air pollutants generated by or released from other processes or equipment.

  (d) Disturbance of surface areas for purposes of land development, not including mining operations or the disturbance of contaminated soil.

  (e) Brazing, soldering, or welding operations.

  (f) Aerosol can usage.

  (g) Road and parking lot paving operations, not including asphalt, sand and gravel, and cement batch plants.

  (h) Fire training activities that are not conducted at permanent fire training facilities.

  (i) Landscaping, janitorial, and site housekeeping activities, including fugitive emissions from landscaping activities.

  (j) Architectural painting.

  (k) Office emissions, including cleaning, copying, and restrooms.

  (l) Wet wash aggregate operations that are solely dedicated to this process.

  (m) Air pollutants that are emitted from personal use by employees or other persons at the source, such as foods, drugs, or cosmetics.

  (n) Air pollutants that are emitted by a laboratory at a facility under the supervision of a technically qualified individual as defined in 40 CFR 720.3(ee); however, this exclusion does not apply to specialty chemical production, pilot plant scale operations, or activities conducted outside the laboratory.

  (o) Maintenance on petroleum liquid handling equipment such as pumps, valves, flanges, and similar pipeline devices and appurtenances when purged and isolated from normal operations.

  (p) Portable steam cleaning equipment.

  (q) Vents on sanitary sewer lines.

  (r) Vents on tanks containing no volatile air pollutants, e.g., any petroleum liquid, not containing Hazardous Air Pollutants, with a Reid Vapor Pressure less than 0.05 psia.

  (2) The following insignificant activities are exempted because of size or production rate and a list of such insignificant activities must be included in the application. The director may require information to verify that the activity is insignificant.

  (a) Emergency heating equipment, using coal, wood, kerosene, fuel oil, natural gas, or LPG for fuel, with a rated capacity less than 50,000 BTU per hour.

  (b) Individual emissions units having the potential to emit less than one ton per year per pollutant of PM10 particulate matter, nitrogen oxides, sulfur dioxide, volatile organic compounds, or carbon monoxide, unless combined emissions from similar small emission units located within the same Part 70 source are greater than five tons per year of any one pollutant. This does not include emissions units that emit air pollutants other than PM10 particulate matter, nitrogen oxides, sulfur dioxide, volatile organic compounds, or carbon monoxide.

  (c) Petroleum industry flares, not associated with refineries, combusting natural gas containing no hydrogen sulfide except in amounts less than 500 parts per million by weight, and having the potential to emit less than five tons per year per air pollutant.

  (d) Road sweeping.

  (e) Road salting and sanding.

  (f) Unpaved public and private roads, except unpaved haul roads located within the boundaries of a stationary source. A haul road means any road normally used to transport people, livestock, product or material by any type of vehicle.

  (g) Non-commercial automotive (car and truck) service stations dispensing less than 6,750 gal. of gasoline/month

  (h) Hazardous Air Pollutants present at less than 1% concentration, or 0.1% for a carcinogen, in a mixture used at a rate of less than 50 tons per year, provided that a National Emission Standards for Hazardous Air Pollutants standard does not specify otherwise.

  (i) Fuel-burning equipment, in which combustion takes place at no greater pressure than one inch of mercury above ambient pressure, with a rated capacity of less than five million BTU per hour using no other fuel than natural gas, or LPG or other mixed gas distributed by a public utility.

  (j) Comfort heating equipment (i.e., boilers, water heaters, air heaters and steam generators) with a rated capacity of less than one million BTU per hour if fueled only by fuel oil numbers 1 - 6.

  (3) Any person may petition the Board to add an activity or emission to the list of Insignificant Activities and Emissions which may be excluded from an operating permit application under (1) or (2) above upon a change in the rule and approval of the rule change by EPA. The petition shall include the following information:

  (a) A complete description of the activity or emission to be added to the list.

  (b) A complete description of all air pollutants that may be emitted by the activity or emission, including emission rate, air pollution control equipment, and calculations used to determine emissions.

  (c) An explanation of why the activity or emission should be exempted from the application requirements for an operating permit.

  (4) The director may determine on a case-by-case basis, insignificant activities and emissions for an individual Part 70 source that may be excluded from an application or that must be listed in the application, but do not require a detailed description. No activity with the potential to emit greater than two tons per year of any criteria pollutant, five tons of a combination of criteria pollutants, 500 pounds of any hazardous air pollutant or one ton of a combination of hazardous air pollutants shall be eligible to be determined an insignificant activity or emission under this subsection (4).
