H.R. 4795 — what changed

In general— In publishing any final rule establishing or revising a national ambient air quality standard, the Administrator shall, as the Administrator determines necessary and appropriate to assist States, permitting authorities, and permit applicants, concurrently publish 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.

Applicability of standard to pre­con­struc­tion permitting— If the Administrator fails to publish final regulations and guidance that include information relating to submission and consideration of a preconstruction permit application under a new or revised national ambient air quality standard concurrently with such standard, then such standard shall not apply to the review and disposition of a preconstruction permit application until the Agency has published such final regulations and guidance.

After publishing regulations and guidance for implementing national ambient air quality standards under subsection (a), nothing in this section shall preclude the Environmental Protection Agency from issuing subsequent regulations or guidance to assist States and facilities in implementing such standards.

Nothing in this section shall be construed to eliminate the obligation of a preconstruction permit applicant to install best available control technology and lowest achievable emissions rate technology, as applicable.
