"NEW ORLEANS — Environmentalists say the Environmental Protection Agency has shot down a request for new regulations to deal with the massive area of low oxygen that crops up every summer in the Gulf of Mexico due to the huge amount of nitrogen and phosphorous from fertilizer, urban runoff and sewage systems that winds up in the Gulf.
Environmental groups in Louisiana, Minnesota, Missouri, Iowa, Tennessee and Kentucky asked EPA to draw up nationwide standards for nutrient pollution."
