In this Act:

(a) Establishment.—Not later than 1 year after the date of enactment of this Act, the Administrator shall establish a program, to be known as the “Early Action Compact Program”, under which State, local, and Tribal governments may develop early action compact plans designed to achieve and maintain the ozone standard.

(b) Notification.—

(1) IN GENERAL.—To be eligible to participate in the Early Action Compact Program, a State, local, or Tribal government shall submit to the Administrator—

(A) on the date on which the applicable State submits to the Administrator the nonattainment recommendations of the State, a notice of the intent of the State, local, or Tribal government to participate in the Early Action Compact Program; and

(B) not later than 1 year after the date on which the State, local, or Tribal government submits the notice under subparagraph (A), an early action compact plan in accordance with section 3.

(2) LIMITATION ON NONATTAINMENT STATUS.—In the case of an area under the jurisdiction of a State, local, or Tribal government that provides a notice under paragraph (1)(A), the Administrator may not designate the area as a nonattainment area under section 107 of the Clean Air Act (42 U.S.C. 7407) until after the Administrator has issued a decision on an early action compact plan of the area under section 4.

(c) Minimum requirements.—The Early Action Compact Program shall include, at a minimum, provisions to ensure—

(1) the use of best available science;

(2) participation by State, local, and Tribal governments through locally crafted solutions;

(3) the voluntary development and implementation by the State, local, and Tribal governments of early action compact plans;

(4) that if a State implementation plan is required due to designation of an area as a nonattainment area following the implementation of an early action compact plan in accordance with this section, the Administrator shall provide credit to applicable State, local, or Tribal governments and industry participants for actions and investments carried out pursuant to the Early Action Compact Program toward ozone attainment; and

(5) that, in the case of the failure of an area to achieve ozone attainment, the Administrator shall defer designation of the area as a nonattainment area for ground-level ozone under section 107 of the Clean Air Act (42 U.S.C. 7407) if that area—

(A) is participating in the Early Action Compact Program; and

(B) is an area in which an early action compact plan is being implemented to improve the air quality of the area.

(a) In general.—Subject to section 6, an early action compact plan entered into under the Early Action Compact Program shall include—

(1) general provisions to ensure—

(A) public involvement in the development of the plan, including—

(B) are designed and implemented by the community with full stakeholder participation;

(C) following the adoption of Federal and State controls to be implemented by the attainment date of the early action compact, identify local control strategies that are—

(i) specific;

(ii) quantifiable;

(iii) permanent; and

(iv) enforceable; and

(D) shall be—

(i) incorporated by the applicable State or Indian Tribe into the State implementation plan; and

(ii) submitted to the Administrator for approval; and

(7) maintenance for growth provisions—

(A) to address increases in emissions at least 5 years beyond the attainment date of the early action compact plan to ensure the area remains in attainment of ozone standards; and

(B) to require continuing planning processes, including—

(i) modeling updates;

(ii) identification of actual new point sources;

(iii) impacts from growth; and
