"U.S. EPA [Thursday] issued its final 'tailoring' rule for greenhouse gas emissions, a contentious policy aimed at shielding small polluters from rigid Clean Air Act permitting requirements."

"There's at least 10 times as much oil spilling into the Gulf of Mexico than official estimates suggest, according to an exclusive NPR analysis."

"The Gulf of Mexico oil spill could grow even more disastrous if the looming hurricane season churns up towering black waves and blasts beaches and crowded cities with oil-soaked gusts, experts warned."

"EPA administrator is blazing trails, from regulating greenhouse gas emissions to reforming chemical management policies."

"Many who think they have food allergies actually do not. A new report, commissioned by the federal government, finds the field is rife with poorly done studies, misdiagnoses and tests that can give misleading results."

"For 11 years, the federal government has been burying nuclear waste in New Mexican salt beds at a place called WIPP, or the Waste Isolation Pilot Plant. It's waste from making atomic weapons. But now the government is looking for a place to put thousands of tons of spent fuel from reactors. These salt beds could be the place."

""A largely ignored contaminant doesn’t just resemble bisphenol A, the chemical found to leach out of hard plastic water bottles. It’s BPA’s fluorinated twin — on steroids."

Sens. John Kerry (D-Mass.) and Joe Lieberman (I-Conn.) released their draft Senate climate and energy bill Wednesday. It pairs a cap-and-trade scheme with major concessions to the fossil-fuel and nuclear industries. Weighing in close to 1,000 pages, it covers a cross section of the nation's top environmental and energy issues. Both business groups and environmental groups have mixed reactions. The big question now is whether the bill can garner enough votes to succeed on the Senate floor.
