SUPPLEMENTARY INFORMATION:

Throughout this document wherever “we,” “us,” or “our” is used, we mean the EPA.

On June 5, 2019 (84 FR 26053), we published in the Federal Register a proposed rule pertaining to proposed approval of a CDD for the 2006 24-hour PM_2.5 Salt Lake City, UT NAA and requested comments by July 5, 2019. Specifically, the proposed determination is based upon quality-assured, quality-controlled, and certified ambient air monitoring data for the period 2016-2018, available in the EPA's Air Quality System (AQS) database, showing the area has monitored attainment of the 2006 24-hour PM_2.5 National Ambient Air Quality Standards (NAAQS). Based on our proposed determination that the Salt Lake City, UT NAA is currently attaining the 24-hour PM_2.5 NAAQS, the EPA also proposed to determine that the obligation for Utah to make submissions to meet certain Clean Air Act (CAA or the Act) requirements related to attainment of the NAAQS for this area is not applicable for as long as the area continues to attain the NAAQS.

We received a request from the Center for Biological Diversity to extend the comment period and, in response, we are extending the comment period to July 22, 2019.^[1]
