  • 2024-27872 — Review of New Source Performance Standards for Stationary Combustion Turbines and Stationary Gas Turbines
    💰
    Type:Proposed Rule
    Citation:89 FR 101306
    Reading Time:about 4 hours

    The Environmental Protection Agency (EPA) is proposing updates to the Standards of Performance for stationary combustion turbines and gas turbines to better control emissions of nitrogen oxides (NOX) and sulfur dioxide (SO2). Based on a review required by the Clean Air Act, these amendments aim to establish new subcategories and lower NOX emission limits by using improved technologies like post-combustion selective catalytic reduction (SCR). These changes are expected to reduce environmental impacts, particularly for new and reconstructed turbines, and address concerns about turbines that may co-fire with hydrogen. The proposal also considers public comments and suggestions regarding technical updates and regulatory simplifications.

    Simple Explanation

    The EPA wants to make power machines like big engines that run on gas cleaner for the air by using new technology to lower bad stuff like smoke that can hurt our air and health. They're also looking at how these machines might work with different fuels, like using a little bit of hydrogen, to make sure these changes help keep the air cleaner.

  • 2021-00864 — Ozone Transport Commission Recommendation that EPA Require Daily Limits for Emissions of Nitrogen Oxides From Certain Sources in Pennsylvania
    Type:Notice
    Citation:86 FR 4049
    Reading Time:about 59 minutes

    The Environmental Protection Agency (EPA) has released a notice about a recommendation from the Ozone Transport Commission (OTC). The recommendation suggests that Pennsylvania should be required to limit nitrogen oxide (NOX) emissions from coal-fired power plants, ensuring that existing pollution control technologies are optimized daily during the ozone season. The goal of these measures is to help reduce pollution and ensure that areas downwind, like Philadelphia and New York City, can meet national air quality standards. The public is invited to submit comments on this recommendation by March 8, 2021, and a public hearing will be held on February 2, 2021.

    Simple Explanation

    The EPA wants to listen to people's thoughts about making sure certain power plants in Pennsylvania do a better job of keeping the air clean, especially during the summer. They’re thinking about using similar rules that other nearby states have to make sure the air is safe for everyone.
