The Environmental Protection Agency plans to release rules to reduce carbon-dioxide emissions from existing power plants by next June and to finalize the rules by June 2015. On Wednesday, it held one of 11 national \u201clistening sessions\u201d at its Denver office.<\/p>\n
President Barack Obama told the EPA to work on the rules, which could be among the country\u2019s most significant steps to reduce greenhouse-gas emissions. Power plants account for 40 percent of U.S. carbon emissions.<\/p>\n
\u201cPower plants are the nation\u2019s single-largest source of carbon pollution, a source we must address as we work to combat climate change,\u201d said Shaun McGrath, the EPA\u2019s regional administrator. \u201cScience tells us that climate change is real, that human activities are fueling that change, and that we must take action now to avoid the most devastating consequences.\u201d<\/p>\n
McGrath\u2019s EPA region stretches as far as North Dakota, and miners and coal company executives traveled from that state, Wyoming and Colorado to protest the EPA\u2019s plans.<\/p>\n
North Dakota state Sen. Jessica Unruh works for a coal mine and has six coal power plants in her district.<\/p>\n
\u201cRequiring these plants to install commercially unproven technology to meet emissions standards could be potentially devastating,\u201d Unruh said.<\/p>\n
And Wade Boeshans, a coal mine manager, said jobs will be at risk if EPA cracks down too hard.<\/p>\n
\u201cIf you\u2019d come to North Dakota, you\u2019d see the respect with which we treat the land we mine,\u201d he said.<\/p>\n
People who worry about climate change also attended the listening session.<\/p>\n
Lt. Gov. Joe Garcia, speaking for Gov. John Hickenlooper, joined environmentalists at a rally in a bookstore across the street from the EPA office.<\/p>\n
Colorado is a leader in reducing carbon emissions, Garcia said, thanks to a 2010 bill that hastened the replacement of coal plants with natural gas.<\/p>\n
Climate change is a very real issue, Garcia said.<\/p>\n
\u201cWe know it has the potential to have broad impacts on our lives and our economy,\u201d he said, citing Colorado\u2019s recent droughts, wildfires and costly floods.<\/p>\n
A technological solution is possible, said Alfred Brown, CEO of Boulder-based Ion Engineering.<\/p>\n
Brown\u2019s company is working on better equipment to capture carbon emissions, which he says should be ready for commercialization by the end of the decade. Carbon capture should increase the costs of operating a coal power plant by about a third \u2013 much less than the current technology \u2013 and Brown thinks companies could recoup much of their costs by selling carbon dioxide. The gas is used to pressurize old oil fields.<\/p>\n
The EPA already has released a rule to cut carbon emissions at future power plants. Environmentalists say the rule is strong enough that it will be impossible to build a traditional coal power plant in the United States without carbon-capture equipment.<\/p>\n
The next step for the EPA \u2013 addressing existing power plants \u2013 is much bigger. Wednesday\u2019s listening session was devoted to the rule for existing plants, which has not been released yet.<\/p>\n
