## Abstract

The Environmental Protection Agency (EPA) is finalizing a clean data determination (CDD) for the 2006 24-hour fine particulate matter (PM<INF>2.5</INF>) Salt Lake City, Utah, (UT) nonattainment area (NAA). 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<INF>2.5</INF> 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<INF>2.5</INF> NAAQS, the EPA is also proposing 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.
