ANNAPOLIS, Md. (AP) — The Chesapeake Bay Foundation is back in court over bay restoration efforts.

The bay advocacy group is holding a press conference Wednesday in Annapolis to discuss legal efforts it is taking, along with other groups, to fight off challenges to the federal Environmental Protection Agency's "pollution diet'" strategy.

Environmentalists and farm advocates are clashing over the new, stricter federally led effort. The American Farm Bureau Federation sued the EPA in January, and other groups have since joined the challenge. Critics say it is too far-reaching and will burden states with huge costs.

The Chesapeake Bay Foundation, which has sued the EPA itself over the slow pace of restoration efforts, says it is being joined by groups including the National Wildlife Federation, the Mid-Shore Riverkeeper Conservancy and Defenders of Wildlife.
