Abstract
The Environmental Protection Agency (EPA) is taking four actions regarding the Kentucky State Implementation Plan (SIP). Specifically, EPA is approving Kentucky's November 16, 2018, SIP submittal seeking to change reliance from the Clean Air Interstate Rule (CAIR) to the Cross-State Air Pollution Rule (CSAPR) for certain regional haze requirements; converting EPA's limited approval/limited disapproval of Kentucky's regional haze SIP to a full approval; removing EPA's Federal Implementation Plan (FIP) for Kentucky which relied on CSAPR to address the deficiencies identified in the limited disapproval of Kentucky's regional haze SIP; and approving the visibility prong of Kentucky's infrastructure SIP submittals for the 1997 8-hour Ozone, 2010 Nitrogen Dioxide (NO<INF>2</INF>), 2010 Sulfur Dioxide (SO<INF>2</INF>), and 2012 Fine Particulate Matter (PM<INF>2.5</INF>) National Ambient Air Quality Standards (NAAQS).
