From Star Tribune:
WASHINGTON, D.C. — Three years ago, an economist for the U.S. Army Corps of Engineers stirred up a tempest by accusing the agency of rigging a study to justify $1 billion in lock upgrades on the upper Mississippi River.
Now the White House is asking the Corps to scrap its plan, saying the latest economic model — which critics say is even worse than the approach challenged by economist Donald Sweeney — is flawed. The White House also proposed increasing environmental spending on the upper Mississippi to $33 million.
The decision by the Office of Management and Budget (OMB) was a setback for Twin Cities-based Cargill Inc., which operates barges on the river and is part of an industry group that says the upgrades are needed to relieve traffic congestion.
Farmers in Minnesota, Iowa and other states who ship grain on the river have also supported the proposal to expand five to seven locks on the Mississippi and the Illinois waterway north of St. Louis.
