A federal appeals court yesterday struck down a Bush administration rule that prevented states and local governments from imposing stricter monitoring of pollution generated by power plants, factories and oil refineries than required by the federal government. In a 2 to 1 decision, a panel of the U.S. Court of Appeals for the District of Columbia Circuit found that the Environmental Protection Agency rule violated a provision of the Clean Air Act, which requires adequate monitoring of emissions to ensure compliance with...

Environmental groups presented a federal official with more than 19,000 signed letters and postcards Tuesday asking the U.S. government to set stricter rules to prevent pollution in the Chesapeake Bay. The presentation, held outside an Environmental Protection Agency building in Annapolis, came eight days before one of the most crucial deadlines in the Chesapeake's recent history. In May, President Obama issued an executive order calling for federal agencies to act more aggressively to help the bay,...

TUESDAY, May 13 (HealthDay News) -- Exposure to coarse airborne-pollution particles, such as those found in windblown dust or stirred up by agricultural work and mechanical grinding, does not appear to be linked to hospital admissions, a new study finds. Coarse particulate matter, or PM10-2.5 for short, is between 2.5 and 10 micrometers or microns (thousandths of a millimeter) in size -- much smaller than a pinhead. To date, research into health risks posed by coarse particulate matter pollution...

Development in the Potomac River's watershed means that much rainwater now bypasses natural filtering systems and washes off of roofs, parking lots and streets carrying a variety of harmful pollutants, according to a report released today. In its second annual "State of the Nation's River" report, an environmental group called the Potomac Conservancy gave the river an overall grade of D-plus -- the same as last year's. In this report, the group focused on problems from "impervious surfaces," the...

The day after the November 2010 elections made clear President Obama's greenhouse-gas legislation was doomed, he vowed to keep trying to curb emissions linked to global warming. There's more than one way of "skinning the cat," he told reporters. Since then, Obama has used his executive powers — including his authority under the 1970 Clean Air Act — to press the most sweeping attack on air pollution in U.S. history. He has imposed the first carbon-dioxide limits on new...
