## Abstract

EPA is taking direct final action to approve State Implementation Plan (SIP) revisions submitted by the Maryland Department of the Environment (MDE) pertaining to the GenOn Chalk Point Generating Station (Chalk Point). These revisions approve specific provisions of a 2011 Consent Decree between MDE and GenOn to reduce particulate matter (PM), sulfur oxides (SO<INF>X</INF>), and nitrogen oxides (NO<INF>X</INF>) from Chalk Point. These revisions also remove the 1978 and 1979 Consent Orders for the Chalk Point generating station from the Maryland SIP as those Consent Orders have been superseded by the 2011 Consent Decree. EPA is approving these SIP revisions because the reductions of PM, SO<INF>X</INF>, and NO<INF>X</INF> are beneficial for reducing ambient levels of the PM, sulfur dioxide (SO<INF>2</INF>), nitrogen dioxide (NO<INF>2</INF>) and ozone. They also reduce visible emissions from Chalk Point. This action is being taken under the Clean Air Act (CAA).
