## Abstract

EPA is approving a State Implementation Plan (SIP) revision submitted by the State of Maryland. This revision does not change current requirements. The intended effect of this action is to approve a change in the terms used in the text of a regulation to more accurately reflect its intended purpose to exempt fuel burning equipment, not installations, from certain general requirements pertaining to sulfur oxides (SO<INF>x</INF>) . EPA is approving these revisions to the Maryland SIP in accordance with the requirements of the Clean Air Act.
