EPA’s Final Standards of Performance Greenhouse Gas Emissions from New, Modified & Reconstructed Electric Generating Units Under section 111(b) of the Clean Air Act
On Aug. 3, 2015, the Environmental Protection Agency (EPA) issued its final rule to regulate greenhouse gas emissions (GHG) from new, modified, and reconstructed electric generating units (EGUs) under Section 111(b) of the Clean Air Act. Specifically, the final rule sets “standards for emissions of carbon dioxide (CO2) for newly constructed, modified, and reconstructed affected fossil fuel-fired…EGUs.” The rule will become effective 60 days after its publication in the Federal Register, which is expected to occur no later than Sept. 4, 2015.
The final rule defines a new source as “any newly constructed fossil fuel-fired power plant that commenced construction on or after Jan. 8, 2014. It defines a modification as “any physical or operational change to an existing source that increases the source’s maximum achievable hourly rate of air pollutant emissions.” The standard for modified sources applies to any units that modify on or after Jan. 18, 2014.
A reconstructed source is defined as “a unit that replaces components to such an extent that the capital cost of the new components exceeds 50 percent of the capital cost of an entirely new comparable facility.” The standard for reconstructed sources would apply to any unit that is reconstructed on or after January 18, 2014.

EPA’s Final Greenhouse Gas Emissions for Existing Electric Generating Units Under section 111(d) of the Clean Air Act
On June 25, 2013, President Obama issued a memorandum directing the U.S. Environmental Protection Agency (EPA) administrator to issue proposed “standards, regulations, or guidelines, as appropriate that address carbon pollution from modified, reconstructed, and existing power plants…” Regulating carbon dioxide (CO2) from power plants is a central component of the Obama Administration’s efforts to address climate change.
Following the President’s directive, on June 2, 2014, EPA proposed emissions guidelines for CO2 emissions from existing fossil fuel-fired power plants. On Aug. 3, 2015, EPA finalized its greenhouse gas emission guidelines for existing electric generating units (EGUs) under section 111(d) of the Clean Air Act (CAA)-the Clean Power Plan (CPP). The agency asserts that the final emission guidelines (or final rule) will reduce CO2 emissions by 32 percent from 2005 levels by 2030, a steeper decline than the 30 percent cut envisioned by the proposed rule, due largely to a greater decline in coal use and greater use of renewables.
