Using a rare veto, the Environmental Protection Agency rejected a federal plan Tuesday for the Army Corps of Engineers to build the world’s largest water pump in the Mississippi Delta.
First authorized by Congress in 1941, the $220 million Yazoo Backwater Pump Project would drain at least 67,000 acres of wetlands in Mississippi's sparsely-populated Yazoo River Basin, which is more than 200 miles northwest of New Orleans (many sources, mostly opponents of the project, say that it would drain up to 200,000 acres). The project would have benefited soybean farmers threatened by flooding, but environmentalists said that it would have harmed water quality and devastated the wetlands, which are home to endangered fish and migratory birds.
The EPA agreed with the environmentalists and vetoed the project under a provision of the Clean Water Act. In a press release announcing the decision, the agency said that the project would have incurred "unacceptable damage to these valuable resources that are used for wildlife, economic, and recreational purposes."
This is only the 12th time that the EPA has issued a veto under the Clean Water Act. In the past, the agency has used the power to block a shopping mall and a dam in other states, but, as the Associated Press notes, the Yazoo project is 10 times larger than the other 11 vetoed projects combined.
