By Maryclaire Dale The Associated Press PHILADELPHIA - A U.S. appeals court on Monday approved a federal plan to limit pollution in the Chesapeake Bay despite objections from farmers, builders and others who accused the Environmental Protection Agency of a power grab.The ruling by the 3rd U.S. Circuit Court of Appeals upheld restrictions on farm and construction runoff and wastewater treatment, and has the support of environmentalists and officials in the six states in the Chesapeake Bay watershed."The Chesapeake Bay (plan) will require sacrifice by many, but that is a consequence of the tremendous effort it will take to restore health to the Bay - to make it once again a part of our 'land of living,' a goal our elected representatives have repeatedly endorsed," Circuit Judge Thomas Ambro wrote, quoting American poet Robert Frost.
