Carbon Pollution Standards for New, Modified and Reconstructed Power Plants: Regulatory Actions

Rule Summary

Carbon Pollution Standards for New, Modified and Reconstructed Power Plants apply to brand new sources built in the future or to an existing unit that meets certain, specific conditions described in the Clean Air Act and implementing regulations for being “modified” or “reconstructed.” In this final action EPA is establishing separate standards for two types of fossil-fuel fired sources:

  • stationary combustion turbines, generally firing natural gas; and
  • electric utility steam generating units, generally firing coal

These final standards reflect the degree of emission limitation achievable through the application of the best system of emission reduction (BSER) that EPA has determined has been adequately demonstrated for each type of unit.
