[JURIST] The Chesapeake Bay Foundation filed a lawsuit Wednesday against the Environmental Protection Agency seeking to force the agency to take action on nitrogen entering the bay and harming animals. According to the environmental group, nitrogen entering the watershed from a variety of sources, such as manure runoff from farms and sewage plants, creates huge algae blooms that choke out other forms of life like fish and crabs. The group has been seeking a permit program on nitrogen releases by sewage plants since last December, but EPA has yet to take action. Read the complaint [PDF] and a press release.
