Traduction automatique locale · Langue originale de la source

Résumé

The Environmental Protection Agency (EPA) is approving a state implementation plan (SIP) revision submitted by the Commonwealth of Pennsylvania. The revision updates the reasonably available control technology (RACT) Plan for the Philadelphia Gas Works, Richmond Plant (PGW Richmond) by removing a condition from the RACT Plan Approval that was incorporated into Pennsylvania's SIP on October 7, 2016. The proposed revision results in no change of emission allowances under RACT. The EPA is approving this revision to the Pennsylvania SIP in accordance with the requirements of the Clean Air Act (CAA).

Air Plan Approval; New York; Athens Generating Plant

The Environmental Protection Agency (EPA) is approving a revision to the State of New York's State Implementation Plan (SIP) for the ozone National Ambient Air Quality Standard (NAAQS) related to a Source-specific SIP (SSSIP) revision for the Athens Generating Plant, located at 9300 US Route 9 West, Athens, NY 12015 (Athens or the Facility). In accordance with the requirements for implementation of the 2008 and 2015 ozone NAAQS, the EPA finds that the control options in New York's SSSIP revision implement Reasonably Available Control Technology (RACT) with respect to Oxides of Nitrogen (NO X ) emissions from the relevant Facility sources, which are identified as three combined-cycle Westinghouse model 501G combustion turbines with associated heat recovery steam generators and steam turbines (identified as Emission Units U-00001, U-00002, and U-00003 in the Facility's Title V permit and New York's submission). This action is being taken in accordance with the requirements of the Clean Air Act (CAA).

Approval of Source-Specific Air Quality Implementation Plan; New York; Calpine JFK Energy Center

The Environmental Protection Agency (EPA or the Agency) is approving a revision to the State of New York's State Implementation Plan (SIP) for the ozone National Ambient Air Quality Standard (NAAQS) related to a source-specific SIP (SSSIP) revision for Calpine JFK Energy Center, located at Kennedy International Airport (JFK), Building 49, Jamaica, NY 11430 (the Facility). The EPA found that the control options in this SSSIP revision implement Reasonably Available Control Technology (RACT) with respect to Oxides of Nitrogen (NO X ) emissions from the relevant Facility sources, which are identified as six mid-size emergency hot water boilers (the Boilers). This SSSIP revision implements NO X RACT for the relevant Facility sources in accordance with the requirements for implementation of the 2008 and 2015 ozone NAAQS. The EPA determined that this action will not interfere with ozone NAAQS requirements and meets all applicable requirements of the Clean Air Act (CAA).

Air Plan Approval; Maryland; Clean Data Determination for the Baltimore, MD Nonattainment Area for the 2015 Ozone National Ambient Air Quality Standards

The Environmental Protection Agency (EPA) is determining that the Baltimore, Maryland (MD) nonattainment area (the Baltimore Area or the Area) has clean data for the 2015 8-hour ozone national ambient air quality standard (NAAQS or standard). This determination is based upon quality-assured, quality-controlled, and certified ambient air monitoring data for the 2022-2024 design value (DV) period showing that the Baltimore Area attained the 2015 ozone NAAQS, with the exclusion of certain monitoring data impacted by exceptional events. The EPA is taking final agency action on portions of three exceptional event (EE) requests submitted by the Maryland Department of the Environment (MDE) on February 2, 2024, on behalf of MD, and concurred on by the EPA on November 12, 2025. As a result of the clean data determination (CDD), under the EPA's Clean Data Policy, the EPA is suspending the requirements for the Baltimore Area to submit attainment demonstrations and associated Reasonably Available Control Measures (RACM), Reasonable Further Progress (RFP) plans, contingency measures, and other planning SIPs related to attainment of the 2015 ozone NAAQS, for as long as the Baltimore Area continu

Approval of Source-Specific Air Quality Implementation Plan; New York; Big Six Towers Inc.

The Environmental Protection Agency (EPA) is proposing to determine a revision to the State of New York's State Implementation Plan (SIP) for the ozone National Ambient Air Quality Standard (NAAQS) related to a source-specific SIP (SSSIP) revision, for Big Six Towers Inc. (the Big Six), located at 59-55 47th Ave. Woodside, NY 11377 (the Facility), is approvable. The EPA is proposing to find that the control options in this SSSIP revision implement Reasonably Available Control Technology (RACT) with respect to oxides of nitrogen (NO X ) emissions from the relevant Facility sources, which are identified as three oil-fired engines. This SSSIP revision is intended to implement NO X RACT for the relevant Facility sources in accordance with the requirements for implementation of the 2008 and 2015 ozone NAAQS. The EPA proposes to determine that this rulemaking will not interfere with ozone NAAQS requirements and meets all applicable requirements of the Clean Air Act (CAA).

Partial Approval and Partial Disapproval of Air Quality Implementation Plans; Hawaii; Regional Haze State Implementation Plan for the Second Implementation Period

The Environmental Protection Agency (EPA) is partially approving and partially disapproving the regional haze state implementation plan (SIP) revision submitted by Hawaii on August 2, 2024, under the Clean Air Act (CAA) and the EPA's Regional Haze Rule (RHR) for the program's second implementation period. Hawaii's SIP submission is intended to address the requirement that states must periodically revise their long-term strategies for making reasonable progress towards the national goal of preventing any future, and remedying any existing, anthropogenic impairment of visibility, including regional haze, in mandatory Class I Federal areas. The SIP submission also addresses other applicable requirements for the second implementation period of the regional haze program. The EPA is approving the portions of Hawaii's submission relating to calculations of baseline, current, and natural visibility conditions, progress to date, the uniform rate of progress, reasonably attributable visibility impairment, progress report requirements, and monitoring strategy and other implementation plan requirements. The EPA is disapproving the long-term strategy, including the enforceable shutdown of sever

Air Plan Approval; Michigan; Determination of Attainment by the Attainment Date for the 2015 Ozone Standards

The Environmental Protection Agency (EPA) is proposing to determine under the Clean Air Act (CAA) that the Detroit, Michigan nonattainment area ("Detroit area" or "area") attained the 2015 ozone National Ambient Air Quality Standards (NAAQS) by the applicable attainment date. This determination relies on the EPA's concurrence on an exceptional events request submitted by the Michigan Department of Environment, Great Lakes, and Energy (EGLE) on February 19, 2026, and concurred on by the EPA on March 24, 2026. Therefore, the EPA is proposing to take final agency action on Michigan's exceptional events request. This action, if finalized, will fulfill the EPA's statutory obligation to determine whether the Detroit area attained the 2015 ozone NAAQS by the Moderate attainment date of August 3, 2024.
