EPA postpones decision that would toughen coal ash rules

McClatchy Newspapers: The Environmental Protection Agency on Tuesday proposed the nation's first federal rules for the disposal of contaminant-laden ash from coal-fired power plants, but delayed a decision for at least three months on whether coal ash should be regulated as a hazardous substance. The ash contains the contaminated remains of coal, including mercury, arsenic, cadmium and other substances that can cause cancer and other illnesses. The EPA's testing has shown that without protections, these ...

Ice cap on west Ugandan mountain range splits

Associated Press: Ugandan wildlife authorities say the ice cap on the country's western Rwenzori mountain range has split after extensive melting caused by global warming.

Guma said Tuesday the split occurred on the climbing route to Mount Margherita and that tourists can no longer climb that peak, but authorities are working to create ...

Gulf Coast bird colonies at risk from oil spill

Reuters: For the birds that nest in the fragile marshes, swamps and barrier islands of the U.S. Gulf Coast, the timing of a massive oil slick threatening the shore could not be worse.

"They are right in the middle of having eggs ...

Perry: Don’t speculate about oil spill

Associated Press: Texas Gov. Rick Perry said Tuesday it's not wise to speculate about what caused an explosion and massive oil spill in the Gulf of Mexico, and he defended his use of the term "act of God" to describe the disaster. Perry said Tuesday the phrase -- which he used in a speech in Washington, D.C., on Monday when discussing the spill -- is a legal definition and that his point is "nobody knows what happened" at the oil rig off the Louisiana coast. The undersea well has been spewing 200,000 ...

EPA proposes coal ash rule, sets time for comment

EPA Administrator Lisa Jackson said Tuesday that one option would regulate the ash under the hazardous waste section of the federal Resource Recovery and Conservation Act. The other is regulating it in the non-hazardous waste section of the law. She said EPA will seek public comment for 90 days before deciding on which method to use. The announcement ...

India: Diatoms reveal freshwater pollution

ScienceDaily: Researchers in India have demonstrated that microscopic aquatic creatures could be used as the ecological equivalent of a canary in a coalmine for assessing inland freshwater lakes and ponds. Writing in the World Review of Science, Technology and Sustainable Development the team explains how diatoms respond badly to pollutants and sewage contamination. Bijaya Kumar Padhi, Jnanendra Rath, and Pratap Kumar Padhy of the Visva-Bharati University, in Santiniketan, India, have looked at the ...
