Lawsuit To Keep Chesapeake Bay Cleanup Commitment. After 25 years of watching promises broken and commitments unfulfilled, the Chesapeake Bay Foundation this week filed a lawsuit in federal court to require the federal Environmental Protection Agency to enforce the law and reduce pollution sufficiently to remove the Chesapeake Bay from the federal ‘impaired waters’ list. The lawsuit was filed in the U.S. District Court for the District of Columbia following a legal requirement for a 60-day notice of intent to sue period (CBF filed the notice on October 29).
