(a)(1) The Division of Environmental Quality shall develop NAAQS state implementation plans.
(2) Each NAAQS state implementation plan shall include the measures necessary for the attainment and maintenance of the National Ambient Air Quality Standard in each air quality control region or portion of an air quality control region within the state.
(b)(1) Except with regard to permitting decisions for major source construction under Part C or D of Title I of the Clean Air Act, 42 U.S.C. § 7470 et seq. or 42 U.S.C. § 7501 et seq., National Ambient Air Quality Standards are not effective until adopted by the Arkansas Pollution Control and Ecology Commission under § 8-4-311(b).

**(a) Definitions** For purposes of this section:
(1) The term “standard of performance” means a standard for emissions of air pollutants which reflects the degree of emission limitation achievable through the application of the best system of emission reduction which (taking into account the cost of achieving such reduction and any nonair quality health and environmental impact and energy requirements) the Administrator determines has been adequately demonstrated.
(2) The term “new source” means any stationary source, the construction or modification of which is commenced after the publication of regulations (or, if earlier, proposed regulations) prescribing a standard of performance under this section which will be applicable to such source.
(3) The term “stationary source” means any building, structure, facility, or installation which emits or may emit any air pollutant. Nothing in subchapter II of this chapter relating to nonroad engines shall be construed to apply to stationary internal combustion engines.
(4) The term “modification” means any physical change in, or change in the method of operation of, a stationary source which increases the amount of any air pollutant emitted by such source or which results in the emission of any air pollutant not previously emitted.
(5) The term “owner or operator” means any person who owns, leases, operates, controls, or supervises a stationary source.
(6) The term “existing source” means any stationary source other than a new source.
(7) The term “technological system of continuous emission reduction” means—
(A) a technological process for production or operation by any source which is inherently low-polluting or nonpolluting, or
(B) a technological system for continuous reduction of the pollution generated by a s

**(a) Definitions** For purposes of this section, except subsection (r)—
(1) **Major source** — The term “major source” means any stationary source or group of stationary sources located within a contiguous area and under common control that emits or has the potential to emit considering controls, in the aggregate, 10 tons per year or more of any hazardous air pollutant or 25 tons per year or more of any combination of hazardous air pollutants. The Administrator may establish a lesser quantity, or in the case of radionuclides different criteria, for a major source than that specified in the previous sentence, on the basis of the potency of the air pollutant, persistence, potential for bioaccumulation, other characteristics of the air pollutant, or other relevant factors.
(2) **Area source** — The term “area source” means any stationary source of hazardous air pollutants that is not a major source. For purposes of this section, the term “area source” shall not include motor vehicles or nonroad vehicles subject to regulation under subchapter II.
(3) **Stationary source** — The term “stationary source” shall have the same meaning as such term has under [section 7411(a) of this title](https://uscode.house.gov/view.xhtml?req=granuleid:USC-prelim-title42-section7411/a&num=0&edition=prelim).

For the purpose of this part—
(1) **Reasonable further progress.—** — The term “reasonable further progress” means such annual incremental reductions in emissions of the relevant air pollutant as are required by this part or may reasonably be required by the Administrator for the purpose of ensuring attainment of the applicable national ambient air quality standard by the applicable date.
(2) **Nonattainment area.—** — The term “nonattainment area” means, for any air pollutant, an area which is designated “nonattainment” with respect to that pollutant within the meaning of [section 7407(d) of this title](https://uscode.house.gov/view.xhtml?req=granuleid:USC-prelim-title42-section7407/d&num=0&edition=prelim).
(3) The term “lowest achievable emission rate” means for any source, that rate of emissions which reflects—
(A) the most stringent emission limitation which is contained in the implementation plan of any State for such class or category of source, unless the owner or operator of the proposed source demonstrates that such limitations are not achievable, or
(B) the most stringent emission limitation which is achieved in practice by such class or category of source, whichever is more stringent.
In no event shall the application of this term permit a proposed new or modified source to emit any pollutant in excess of the amount allowable under applicable new source standards of performance.
(4) The terms “modifications” and “modified” mean the same as the term “modification” as used in [section 7411(a)(4) of this title](https://uscode.house.gov/view.xhtml?req=granuleid:USC-prelim-title42-section7411/a/4&num=0&edition=prelim).
