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 PM2.5 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 PM2.5 National Ambient Air 
Quality Standards (NAAQS). Based on our proposed determination that the 
Salt Lake City, UT NAA is currently attaining the 24-hour 
PM2.5 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\

initial email response, appears in the docket for this action.
