Proposal: NSPS for GHG Emissions from New, Modified, and Reconstructed EGUs

Pollutant-Specific Contribution Finding for GHG Emissions from New , Modified and Reconstructed EGUs, and Process for Determining Significance of Other NSPS Source Categories
In January 2021,  EPA provided a framework for criteria for making a significant contribution finding for greenhouse gas emissions from a source category, for the purpose of regulating those emissions under section 111(b) of the Clean Air Act. 

Affordable Clean Energy (ACE) rule
In June 2019, EPA issued ACE, which establishes emission guidelines for states to use when developing plans to limit carbon dioxide at their coal-fired electric generating units. In this notice, EPA also repealed the CPP, and issued new implementing regulations for ACE and future rules under section 111(d). 

On December 6, 2018, EPA proposed to revise the New Source Performance Standards (NSPS) for greenhouse gas emissions from new, modified, and reconstructed fossil fuel-fired power plants. After further analysis and review, EPA proposes to determine that the best system of emission reduction (BSER) for newly constructed coal-fired units, is the most efficient demonstrated steam cycle in combination with the best operating practices. This proposed BSER would replace the determination from the 2015 rule, which identified the BSER as partial carbon capture and storage. The primary reason for this proposed revision is the high costs and limited geographic availability of CCS.
