Notice of Availability of Interim Congestion Mitigation and Air Quality Improvement (CMAQ) Program Guidance as Revised by the Bipartisan Infrastructure Law (BIL)

Notice of availability of Interim Guidance; request for comment.

This notice announces the availability of FHWA CMAQ Program Interim Guidance (Interim Guidance). The Interim Guidance provides information and guidance on eligibility, transfer, and other CMAQ Program requirements under the BIL, enacted as the Infrastructure Investment and Jobs Act. The CMAQ Program requirements in the BIL took effect on October 1, 2021, and apply to all funding obligated on or after that date, whether carryover or new. Because the CMAQ Program requirements in the BIL are in effect and the Interim Guidance contains information that is needed to plan CMAQ-funded projects and use CMAQ funds, the Interim Guidance is effective on the date of publication of this notice in the Federal Register. The Interim Guidance replaces the November 12, 2013 Interim CMAQ Program Guidance under MAP-21 and the July 2014 Revised Interim Guidance on CMAQ Operating Assistance under MAP-21. The FHWA invites public comments on the Interim Guidance and will consider all timely comments submitted to the docket in developing final guidance.
