The Environmental Protection Agency (EPA) is promulgating a Federal implementation plan (FIP) for the Commonwealth of Pennsylvania (Pennsylvania or the Commonwealth). This FIP sets emission limits for nitrogen oxides (NO<INF>X</INF>) emitted from coal-fired electric generating units (EGUs) equipped with selective catalytic reduction (SCR) in Pennsylvania in order to meet the reasonably available control technology (RACT) requirements for the 1997 and 2008 ozone national ambient air quality standards (NAAQS).

Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision from the New Mexico Environment Department (NMED) submitted on October 17, 2016, on behalf of the Albuquerque-Bernalillo County Air Quality Control Board (Air Board). The submittal is in response to the EPA's national SIP call on June 12, 2015, concerning excess emissions during periods of Startup, Shutdown, and Malfunction (SSM).

The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the state of New York. The revision provides the State's control measures for facilities within its borders subject to EPA's 2016 Control Techniques Guideline (CTG) for the oil and natural gas industry. The intended effect of this action is to approve this item into the New York SIP and satisfy the requirement for the CTG. This action is being taken in accordance with the requirements of the Clean Air Act (CAA).

The Environmental Protection Agency (EPA) is proposing a limited approval and limited disapproval of two revised rules and an approval of a rule recission to the South Coast Air Quality Management District (SCAQMD) portion of the California State Implementation Plan (SIP). These revisions concern emissions of volatile organic compounds (VOCs) from marine and pleasure craft coating operations and the coating of metals. The EPA previously proposed to fully approve these SIP revisions on the grounds that they satisfied the relevant requirements under the Clean Air Act (CAA or the Act).
