The Environmental Protection Agency (EPA) is finalizing the removal of the air pollution nuisance rule from the Ohio State Implementation Plan (SIP) using a Clean Air Act (CAA) error correction provision. EPA has determined that this rule was not relied upon by Ohio to demonstrate implementation, maintenance or enforcement of any national ambient air quality standard (NAAQS). Upon the effective date of this action, the nuisance rule will no longer be part of the Ohio SIP.

The Environmental Protection Agency (EPA) has determined that the Salt Lake City, Utah and Provo, Utah Serious nonattainment areas (NAAs) attained the 2006 24-hour fine particulate matter (PM<INF>2.5</INF>) National Ambient Air Quality Standards (NAAQS) by the December 31, 2019 ``Serious'' area attainment date. The determination is based on quality-assured, quality-controlled and certified ambient air quality monitoring data from 2017 through 2019, available in the EPA's Air Quality System (AQS) database.
