Summary

The Administrator may create a "transport region" when they believe pollution blowing across state lines is causing another state to fail the national air-quality standard. The Administrator can act on their own or after a governor asks. They can add any state or part of a state to the region if it significantly contributes to the problem, or remove a state or part of a state if controlling emissions there will not help the region meet the standard. When a region is set up, the Administrator must form a transport commission. Members must include each region governor (or a designee), the Administrator (or a designee), the affected EPA Regional Administrators (or designees), and a state air pollution official from each state. The commission studies how pollution moves across the region, suggests ways to reduce it, and recommends measures so state plans meet section 7410(a)(2)(D). The commission can ask the Administrator to declare a state's plan substantially inadequate under section 7410(k)(5). The Administrator must decide to approve, disapprove, or partially approve that request within 18 months, allow public input, respond to each commission recommendation, and issue the finding if approving. That decision is final under section 7607(b). The commission is not subject to chapter 10 of title 5.

(a)Whenever, on the Administrator’s own motion or by petition from the Governor of any State, the Administrator has reason to believe that the interstate transport of air pollutants from one or more States contributes significantly to a violation of a national ambient air quality standard in one or more other States, the Administrator may establish, by rule, a transport region for such pollutant that includes such States. The Administrator, on the Administrator’s own motion or upon petition from the Governor of any State, or upon the recommendation of a transport commission established under subsection (b), may—
(1)add any State or portion of a State to any region established under this subsection whenever the Administrator has reason to believe that the interstate transport of air pollutants from such State significantly contributes to a violation of the standard in the transport region, or
(2)remove any State or portion of a State from the region whenever the Administrator has reason to believe that the control of emissions in that State or portion of the State pursuant to this section will not significantly contribute to the attainment of the standard in any area in the region.
(b)(1)Whenever the Administrator establishes a transport region under subsection (a), the Administrator shall establish a transport commission comprised of (at a minimum) each of the following members:
(A)The Governor of each State in the region or the designee of each such Governor.
(B)The Administrator or the Administrator’s designee.
(C)The Regional Administrator (or the Administrator’s designee) for each Regional Office for each Environmental Protection Agency Region affected by the transport region concerned.
(D)An air pollution control official representing each State in the region, appointed by the Governor.
(2)The transport commission shall assess the degree of interstate transport of the pollutant or precursors to the pollutant throughout the transport region, assess strategies for mitigating the interstate pollution, and recommend to the Administrator such measures as the Commission determines to be necessary to ensure that the plans for the relevant States meet the requirements of section 7410(a)(2)(D) of this title. Such commission shall not be subject to the provisions of chapter 10 of title 5.
(c)A transport commission established under subsection (b) may request the Administrator to issue a finding under section 7410(k)(5) of this title that the implementation plan for one or more of the States in the transport region is substantially inadequate to meet the requirements of section 7410(a)(2)(D) of this title. The Administrator shall approve, disapprove, or partially approve and partially disapprove such a request within 18 months of its receipt and, to the extent the Administrator approves such request, issue the finding under section 7410(k)(5) of this title at the time of such approval. In acting on such request, the Administrator shall provide an opportunity for public participation and shall address each specific recommendation made by the commission. Approval or disapproval of such a request shall constitute final agency action within the meaning of section 7607(b) of this title.
