HELENA — U.S. Rep. Denny Rehberg, R-Mont., said Thursday he has joined 150 fellow House members in co-sponsoring a bill to block the Environmental Protection Agency from regulating greenhouse gases, which are seen as the chief cause of global warming. “This decision (by the EPA) means the federal government now has the authority to regulate everything from carbon-dioxide to water vapor,” Rehberg said in a statement. “This is an effort to pour concrete into the gears of an economic recovery.”
The EPA last year declared six greenhouse gases to be pollutants subject to Clean Air Act regulation, and began its own rule-making progress to regulate them. Unless Congress acts to block the EPA initiative, the rules could be issued as soon as March, state environmental officials have said.
The greenhouse gases to be regulated include carbon dioxide, but not water vapor. Richard Opper, director of the state Department of Environmental Quality, said the EPA has never proposed to regulate water vapor. “If that were true, then Denny Rehberg and a lot of people like myself probably would have been fined by the EPA,” Opper said Thursday.
However, the bill co-sponsored by Rehberg does explicitly prohibit the EPA from declaring water vapor to be a pollutant, as well as the six greenhouse gases that EPA is preparing to regulate.
