(1) The permit exemptions listed in paragraph (4) of this rule do not apply if an air contaminant source is subject to a standard or requirement contained in the following, except if the air contaminant source belongs to a source category listed in paragraph (5) of Rule 1200-03-09-.07, even if the source itself is not eligible for authorization, or except where specifically stated: Chapter 0400-30-38 (Emission Standards for Hazardous Air Pollutants);
Chapter 1200-03-18 (Volatile Organic Compounds);
Chapter 1200-03-19 (Emission Standards and Monitoring Requirements for Additional Control Areas);
Chapter 1200-03-22 (Lead Emission Standards);
Chapter 1200-03-27 (Nitrogen Oxides); and
Paragraph (2) of Rule 1200-03-31-.05 (Standards for New Sources).
In addition, the exemption provided for the air contaminant sources in paragraph (4) of this rule does not exempt the sources from inclusion in determining if a major stationary source or major modification construction permit is required under paragraphs (4) and (5) of Rule 1200-03-09-.01.
(4) The list of exempted air contaminant sources contained in this paragraph shall not be used as "insignificant activities" or "insignificant emission units" when applying for a major source operating permit under paragraph 1200-03-09-.02(11). These exemptions shall not be used to lower the source's potential to emit below "major source" applicability thresholds or to avoid any "applicable requirement". Otherwise, no person shall be required to obtain or file a request for a permit due to ownership, operation, construction, or modification of the following types of air contaminant sources unless specifically required to do so by the Board or as provided for in paragraph (3) of this rule: (a) Any "insignificant activity" or "insignificant emissions unit": In order to receive designation as an "insignificant activity" or "insignificant emissions unit", a written notification must be submitted to the Technical Secretary. The notification for designation shall include calculations and sufficient documentation to substantiate the applicant's claim. Upon receipt of the notification, the Technical Secretary will respond with a determination of agreement or disagreement with the applicant's claim. In issuance of determination as "insignificant", the Technical Secretary may base the determination upon any criteria that are relevant to the determination. For new sources, the request for designation must be made at least 30 days prior to the estimated starting date of construction. For new sources, if it is determined that the emissions unit does not qualify as an "insignificant emissions unit", the source must apply for a construction permit. The request for designation as an "insignificant emissions unit" may be made at any time for an existing source. In the absence of being designated as an "insignificant emissions unit" by the Technical Secretary under subparagraph 1200-03-09-.04(4)(a) or in the absence of being exempt under subparagraphs 1200-03-09-.04(4)(b) or 1200-03-09-.04(4)(c), any emission unit or activity must have a valid construction and / or operating permit.
(b) The categorical emission units or activities listed in subparagraph 1200-03-09-.04(5)(f), excluding parts 1. and 2. To be categorically insignificant, with the exception of parts 19. and 84., the emissions unit or activity must have a potential to emit less than 5 tons per year of each air contaminant and each regulated air pollutant that is not a hazardous air pollutant, and less than 1,000 pounds per year of each hazardous air pollutant. Such emission units or activities, with the exception of parts 19. and 84., are not required to be listed in the construction or operating permit applications for the facility.
(c) The emission units or activities listed in subparagraph 1200-03-09-.04(5)(g). Such emission units or activities are not required to be listed in the construction or operating permit applications for the facility.(d) Any one of the following emission units or activities: Such emission units or activities are not required to be listed in the construction or operating permit applications for the facility.

This exemption shall not apply where the total capacity of such equipment operated by one person exceeds 2.00 million Btu per hour.2. Single stack of an air contaminant source that emits no hazardous air contaminants or pollutants, and which does not have the potential for emitting more than 0.50 pounds per hour of nonhazardous particulates and 0.5 pounds per hour of any regulated nonhazardous gas (particulates and gases not defined as hazardous air contaminants or pollutants), provided that the total potential particulate emissions from the air contaminant source amounts to less than two (2) pounds per hour, and the total regulated gaseous emissions from the air contaminant source amounts to less than two (2) pounds per hour. For the purpose of this part, an air contaminant source includes all sources located within a contiguous area, and under common control.3.

Temporary-use air curtain destructors or temporary-use air curtain incinerators used in disaster recovery solely for disposal of materials resulting from a natural disaster, and when conducted in conformity with the following conditions: (i) Fires disposing of structural and household materials and vegetation are allowed only when those structures or materials are destroyed or severely damaged by natural disaster. The air curtain destructor or air curtain incinerator shall only be used to combust debris in an area declared a State of Emergency by a local or State government, or the President, under the authority of the Stafford Act, has declared that an emergency or a major disaster exists in the area. Input from Emergency Management personnel may be requested in determining qualification with this criterion.(ii) The maximum rated capacity for each temporary-use air curtain destructor or temporary-use air curtain incinerator shall not exceed 35 tons per day per unit.(iii) The persons using temporary-use air curtain destructors or temporary-use air curtain incinerators under this provision must make a reasonable effort to remove all tires and other rubber products, vinyl shingles and siding, vinyl flooring, carpet, other plastics, asphalt shingles and other asphalt roofing materials, and/or asbestos containing materials from the materials to be burned before ignition. The Technical Secretary reserves the right to inspect the proposed materials to be burned before ignition. The alternative use of chippers and grinders, landfilling, or on-site burial of waste in lieu of burning, if lawful, is encouraged.(iv) The person responsible for such burning must notify the Division of Air Pollution Control of the proposed location. The notification must be delivered to the Division of Air Pollution Control at the appropriate regional Environmental Field Office at least three (3) days prior to commencing the burn. The Division may request that alternate sites be identified to minimize impact to air quality. The alternative use of chippers and grinders in lieu of burning is encouraged.(v) No fire shall be ignited while any air pollution emergency episode is in effect in the area of the burn.(vi) The air curtain destructor or air curtain incinerator shall only be used during a period that begins on the date the unit started operation and lasts 8 weeks or less within the boundaries of the same emergency or disaster declaration area.(vii) Disposal via temporary-use air curtain destructors or temporary-use air curtain incinerators conducted under this exception is only allowed where no other safe and/or practical means of disposal is available.(viii) The Technical Secretary reserves the right to require a person to cease or limit burning if emissions from the air curtain destructor or air curtain incinerator are deemed by the Technical Secretary or his designee to jeopardize public health or welfare, create a public nuisance or safety hazard, create a potential safety hazard, or interfere with the attainment or maintenance of the air quality standards.
