The Chesapeake Bay Foundation is back in court over bay restoration efforts.

The bay advocacy group announced Wednesday that it is siding with the Environmental Protection Agency in a dispute with farm groups over its bay restoration strategy.

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

The foundation says it is filing a motion to intervene in U.S. District Court for the Middle District of Pennsylvania. The foundation, which has sued the EPA 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.
