Dredging EIS On Missouri River Rejected By EPA

EPA has determined that the U.S. Army Corps of Engineers (USACE) Draft Environmental Impact Statement presents insufficient scientific information to support dredging permits allowing sand and gravel removal from the Missouri River. The USACE proposal would allow the removal of 11,615,000 tons per year of main channel river bottom material.

Under the National Environmental Policy Act and Clean Air Act, EPA is required to review the environmental impact of federal proposals. The Corps of Engineers will consider EPA’s comments as it prepares a final Environmental Impact Statement (EIS). The final EIS will contain the Corps’ preferred dredging amount.

According to EPA, dredging is one of several factors contributing to riverbed degradation. Riverbed degradation can threaten bank stability, erode levee foundations and eliminate adjacent wetlands. Dredging usually occurs in close geographic proximity to locations where the construction need is greatest, such as cities along the Missouri River including Jefferson City, Kansas City, St. Charles and St. Joseph, MO. Active commercial sand and gravel dredging in the lower Missouri River began in the 1930s largely to support construction and road building. Sand and gravel dredging removal has increased from 250,000 tons per year in 1935 to about seven million tons in recent years.
