"EPA approves" means full approval, interim approval, or partial approval by EPA. "Equivalent unadulterated fuels" means used oils that have been refined such that the content of toxic additives or contaminants in the oil are no greater than those in unadulterated fossil fuels. "Facility" means all of the pollutant emitting activities, except transportation facilities as defined under Rule .0802 of this Subchapter, that are located on one or more adjacent properties under common control. "Federally enforceable" or "federal-enforceable" means enforceable by EPA. "Fuel combustion equipment" means any fuel burning source covered under 15A NCAC 2D .0503, .0504, .0536, or 40 CFR Part 60 Subpart D, Da, Db, or Dc. "Green wood" means wood with a moisture content of 18% or more. "Hazardous air pollutant" means any pollutant which has been listed pursuant to Section 112(b) of the federal Clean Air Act. Pollutants listed only in 15A NCAC 02D .1104 (Toxic Air Pollutant Guidelines), but not pursuant to Section 112(b), are not included in this definition. "Insignificant activities" means activities defined as insignificant activities because of category or as insignificant activities because of size or production rate under Rule .0503 of this Subchapter. "Lesser quantity cutoff" means:



(a)



for a source subject to the requirements of Section 112(d) or (j) of the federal Clean Air Act, the level of emissions of hazardous air pollutants below which the following are not required:



(i)



(ii) (iii)



maximum achievable control technology (MACT) or generally available control technology (GACT), including work practice standards, requirement under Section 112(d) of the federal Clean Air Act; a MACT standard established under Section 112(j) of the federal Clean Air Act; or substitute MACT or GACT adopted under Section 112(l) of the federal Clean Air Act.



(b)



(c)



for modification of a source subject to, or may be subject to, the requirements of Section 112(g) of the federal Clean Air Act, the level of emissions of hazardous air pollutants below which MACT is not required to be applied under Section 112(g) of the federal Clean Air Act; or for all other sources, potential emissions of each hazardous air pollutant below 10 tons per year and the aggregate potential emissions of all hazardous air pollutants below 25 tons per year.

"Major facility" means a major source as defined under 40 CFR 70.2. "Modification" means any physical change or change in method of operation that results in a change in emissions or affects compliance status of the source or facility. "Owner or operator" means any person who owns, leases, operates, controls, or supervises a facility, source, or air pollution control equipment. "Peak shaving generator" means a generator that is located at a facility and is used only to serve that facility's on-site electrical load during peak demand periods for the purpose of reducing the cost of electricity; it does not generate electricity for resale. A peak shaving generator may also be used for emergency backup. "Permit" means the legally binding written document, including any revisions thereto, issued pursuant to G.S. 143-215.108 to the owner or operator of a facility or source that emits one or more air pollutants and that allows that facility or source to operate in compliance with G.S. 143-215.108.

Such physical or operational limitations include air pollution control equipment and restrictions on hours of operation or on the type or amount of material combusted, stored, or processed. Potential emissions include fugitive emissions as specified in the definition of major source in 40 CFR 70.2. Potential emissions do not include a facility's secondary emissions such as those from motor vehicles associated with the facility and do not include emissions from insignificant activities because of category as defined under Rule .0503 of this Section. If a rule
