## Abstract

EPA is approving State Implementation Plan (SIP) revisions submitted by the Virginia Department of Environmental Quality (VADEQ). These revisions require nitrogen oxides (NO<INF>X</INF>) emission reductions from four large stationary internal combustion (IC) engines and a large cement kiln located in the Commonwealth of Virginia. The intended effect of this action is to approve permitted emission limits that enable Virginia to meet its remaining NO<INF>X</INF> reduction obligations under the NO<INF>X</INF> SIP Call.
