Tradução automática local · Idioma original da fonte

Resumo

EPA is finalizing a full approval of some revisions to the Arizona Department of Environmental Quality (ADEQ) portion of the Arizona State Implementation Plan (SIP) and a limited approval/limited disapproval of another revision to the SIP. This action was proposed in the Federal Register on May 14, 2004 and concerns sulfur dioxide (SO 2 ) emissions from existing primary copper smelters.

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; 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).
