(a)
Proposed regulations— In publishing any final rule establishing or revising a national ambient air quality standard, the Administrator shall, as the Administrator determines to be necessary and appropriate to assist States, permitting authorities, and permit applicants, concurrently publish proposed regulations and guidance for implementing the standard, including information relating to submission and consideration of a preconstruction permit application under the new or revised standard.
(b)
Applicability of standard to preconstruction permitting— A new or revised national ambient air quality standard shall not apply to the review and disposition of a preconstruction permit application until the Administrator publishes final implementation regulations and guidance that include information relating to submission and consideration of a preconstruction permit application under the standard.
(c)
Effect of section—
(1)
In general— After publishing regulations and guidance for implementing national ambient air quality standards under subsection (a), nothing in this section precludes the Administrator from issuing subsequent regulations or guidance to assist States and facilities in implementing those standards.
(2)
Requirements of applicants— Nothing in this section eliminates the obligation of a preconstruction permit applicant to install best available control technology and lowest achievable emission rate technology, as applicable.
(3)
State, local, and tribal authority— Nothing in this section limits the authority of a State, local, or tribal permitting authority to impose emission requirements pursuant to State, local, or tribal law that are more stringent than the applicable Federal national ambient air quality standards established by the Environmental Protection Agency.
