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.
