## Abstract

The Environmental Protection Agency (EPA) is revising our December 14, 2020 action that fully approved two state implementation plan (SIP) revisions, both submitted to EPA on August 13, 2018 by the Commonwealth of Pennsylvania, through the Pennsylvania Department of Environmental Protection (PADEP). Those SIP revisions addressed reasonably available control technology (RACT) requirements for the 2008 ozone national ambient air quality standards (NAAQS), including those related to control techniques guidelines (CTGs) for volatile organic compounds (VOC) and the addition of regulations controlling VOC emissions from industrial cleaning solvents. The SIP revisions also included certain clarifying amendments to Pennsylvania code related to major source RACT regulations. Upon reconsideration, EPA is revising our prior action to partially approve and partially disapprove the August 13, 2018 submittals. Specifically, EPA is approving certain clarifying amendments as well as a negative declaration submitted by PADEP. EPA is disapproving the remainder of both SIP submittals related to CTGs and control of VOC emissions from industrial cleaning solvents. This action is being taken under the Clean Air Act (CAA).
