  • 2021-03985 — Air Plan Approval; Illinois; Removal of Variance for Illinois Power Holdings and AmerenEnergy Medina Valley Cogen Facilities
    Type:Rule
    Citation:86 FR 11872
    Reading Time:about 6 minutes

    The Environmental Protection Agency (EPA) is approving changes to the Illinois State Implementation Plan (SIP) that were submitted by the Illinois Environmental Protection Agency on January 23, 2020. This change removes certain allowances, known as variances, that were previously granted to the Illinois Power Holdings and AmerenEnergy Medina Valley Cogen facilities, specifically regarding sulfur dioxide emission standards. As a result, stricter limits on emissions will be applied to all current coal-fired electrical generating units at these facilities. The changes will take effect on March 31, 2021.

    Simple Explanation

    The EPA is making rules to make sure two big power companies in Illinois stop getting special permissions to put out lots of a bad-smelling gas, sulfur dioxide, from their coal plants. Now, these companies will have to follow stricter rules to keep the air cleaner.

  • 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.

  • 2021-04063 — Air Plan Approval; Tennessee; Emissions Inventory and Nonattainment New Source Review Plan for Sullivan County SO2 Nonattainment Area
    Type:Rule
    Citation:86 FR 11873
    Reading Time:about 11 minutes

    The Environmental Protection Agency (EPA) has approved certain parts of Tennessee's plan to manage air quality in the Sullivan County area, specifically those related to controlling sulfur dioxide (SO₂) emissions. This decision follows the state’s efforts to meet federal standards set in 2010, which aim to limit air pollution from new and modified sources. While the EPA is not taking action on all submissions from Tennessee, they have concluded that the state has fulfilled key requirements, including providing a detailed emissions inventory and adhering to rules for reviewing new sources of pollution. This rule takes effect on March 31, 2021.

    Simple Explanation

    The EPA said that Tennessee made a plan to help clean the air around a place where a factory makes chemicals. They checked and agreed that Tennessee did some important steps, like listing all the polluting stuff, to make sure the air gets better by the end of March 2021.
