Approval and Promulgation of Air Quality Implementation Plans; Oregon; Removal of Perchloroethylene Dry Cleaning Systems Rules

Lokale automatische vertaling · Oorspronkelijke brontaal

Samenvatting

EPA is taking direct final action to approve a revision to the Oregon State Implementation Plan and repeal rules which are no longer required by the Clean Air Act. The revision consists of the repeal of Oregon's control technology guidelines for perchloroethylene (perc) dry cleaning systems and related definitions and provisions. Perc is a solvent commonly used in dry cleaning, maskant operations, and degreasing operations. In 1996, EPA excluded perc from the Federal definition of volatile organic compounds for the purpose of preparing state implementation plans to attain the national ambient air quality standards for ozone under title I of the Clean Air Act. Emissions from perc dry cleaners continue to be regulated as hazardous air pollutants under the National Emissions Standards for Hazardous Air Pollutants.

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).

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).
