EGUs (more commonly referred to as power plants) are the largest anthropogenic source of greenhouse gas emissions, accounting for about one-third of total U.S. GHGs. If the country is going to reduce its GHG emissions by significant amounts, as the President has committed to do, emissions from these sources will almost certainly need to be controlled. \nThe President addressed this issue by directing EPA to re-propose GHG emission standards for new EGUs by September 20, 2013. He also directed the agency to propose guidelines for existing power plants by June 2014, and finalize them a year later. \nEPA had already proposed standards for new sources in April 2012, but the public comment period had generated more than 2.5 million comments\u2014the most ever for a proposed EPA rule\u2014and the agency had not yet finalized the rule. \nThe re-proposed standards were released September 20. They would set an emissions limit of 1,100 pounds of carbon dioxide (CO2) per megawatt-hour (MWh) of electricity generated by new coal-fired EGUs, and a standard of either 1,000 or 1,100 lbs/MWh (depending on size) for new natural gas-fired plants. Coal-fired plants would find it impossible to meet the standard without controls to capture, compress, and store underground about 40% of the CO2 they produce\u2014a technology referred to as carbon capture and storage (CCS). \nUnder the Clean Air Act, the EPA Administrator has a great deal of flexibility in setting these standards. The statute requires that New Source Performance Standards (NSPS) reflect the degree of emission limitation achievable through application of the best system of emission reduction that has been \u201cadequately demonstrated.\u201d The Administrator can take costs, health impacts, environmental impacts, and energy requirements into account in determining what has been adequately demonstrated. \nMany in the electric power and coal industries maintain that CCS has not been adequately demonstrated. Given the high cost and energy use of CCS components, they view the re-proposed standards as effectively prohibiting the construction of new coal-fired power plants. \nEPA, on the other hand, states that the components of CCS technology have been demonstrated on numerous facilities. Details are provided in the preamble to the proposed rule. Despite this, the agency concludes that no coal-fired EGUs (other than DOE-sponsored or other demonstration projects) will be built in the next 10 years regardless of whether the rule is finalized, and therefore no units will be required to use CCS before EPA must review the standard. Given the projected low cost and abundance of natural gas, all new fossil-fueled units are likely to be powered by gas, according to EPA. The standard proposed for these facilities (combined cycle natural gas units) can be met without add-on emission controls, according to the agency.\nAlthough the September 20 proposal would only affect new EGUs, the potential impacts of the rule\u2019s issuance extend beyond these sources, because the agency is obligated under Section 111(d) of the Clean Air Act to promulgate guidelines for existing sources within a category when it promulgates GHG standards for new sources. The President directed EPA to propose such guidelines by June 2014 and to finalize them a year later. Using these guidelines, states will be required to develop performance standards for existing sources. These could be less stringent than the NSPS\u2014taking into account, among other factors, the remaining useful life of the existing source\u2014but the standards could have far greater impact than the NSPS, given that they will affect all existing sources. \nMany in Congress oppose GHG emission standards. In the 113th Congress, hearings have been held and several bills to prohibit or limit EPA GHG standards have been introduced. The proposed standards have stirred new interest in congressional action.", "type": "CRS Report", "typeId": "REPORTS", "active": false, "formats": [ { "format": "HTML", "encoding": "utf-8", "url": "http://www.crs.gov/Reports/R43127", "sha1": "1e3f36a75fa267767ab0b51348a1cdbf1aa65764", "filename": "files/20131115_R43127_1e3f36a75fa267767ab0b51348a1cdbf1aa65764.html", "images": null }, { "format": "PDF", "encoding": null, "url": "http://www.crs.gov/Reports/pdf/R43127", "sha1": "4654d10e0cf6ffc3dfa955c435a1e3d8998a5ed4", "filename": "files/20131115_R43127_4654d10e0cf6ffc3dfa955c435a1e3d8998a5ed4.pdf", "images": null } ], "topics": [] }, { "source": "University of North Texas Libraries Government Documents Department", "sourceLink": "https://digital.library.unt.edu/ark:/67531/metadc227877/", "id": "R43127_2013Sep30", "date": "2013-09-30", "retrieved": "2013-11-05T18:07:05", "title": "EPA Standards for Greenhouse Gas Emissions from Power Plants: Many Questions, Some Answers", "summary": "This report discusses the Environmental Protection Agency (EPA), and the New Source Performance Standards (NSPS) proposals for electric generating units (EGU) Greenhouse Gas Emissions.", "type": "CRS Report", "typeId": "REPORT", "active": false, "formats": [ { "format": "PDF", "filename": "files/20130930_R43127_0725aedd19e14e235f9cf18eed5616f81d459398.pdf" }, { "format": "HTML", "filename": "files/20130930_R43127_0725aedd19e14e235f9cf18eed5616f81d459398.html" } ], "topics": [ { "source": "LIV", "id": "Greenhouse gases", "name": "Greenhouse gases" }, { "source": "LIV", "id": "Environmental protection", "name": "Environmental protection" }, { "source": "LIV", "id": "Alternative energy sources", "name": "Alternative energy sources" } ] } ], "topics": [ "American Law" ] }
