"I want the Mississippi River to be a living, healthy ecosystem and not a highway for barges," said Debbie Neustadt of Des Moines, who volunteers for the Sierra Club . Farmers ask for more river locks, environmentalists disagree 03/22/2002 Associated Press Newswires Copyright 2002. The Associated Press. All Rights Reserved. DAVENPORT, Iowa (AP) - Farmers and businessmen pushed for a quick resolution of a nine-year, $57 million study of the Upper Mississippi River and Illinois Waterway navigation system and urged that new locks be built. Environmentalists said the need for new locks has been overstated and the efficiency of river transportation over rail and roads has been exaggerated. The U.S. Army Corps of Engineers convened a public hearing Thursday night to unveil its revamped study, which resumed last August. The meeting, the last in a series of five over the past week, is the first time in two years the Corps has held public hearings on the study. Much of the session was a recitation of what occurred since the study began in 1993 and how it was restructured in the wake of investigations sparked by a whistleblower. When the 200 people in the audience were invited to speak, many farmers and businessmen wanted the plan to include five new locks on the Mississippi from Canton, Mo., to north of St. Louis and two on the Illinois Waterway. Some also pushed 1,200-foot guide wall extensions at four lock sites surrounding the Quad-Cities. "It's time to bring this process to a close," said Denny Denton, a Princeton, Ill., farmer, who represented the Illinois Corn Growers Association and the state's Farm Bureau. He and others talked about the lost income to farmers from congestion on the river's navigation system. Farm interests estimate that $364 million will be lost per year by 2020 if the navigation system is not improved. Representatives of environmental groups said less would be better. "I want the Mississippi River to be a living, healthy ecosystem and not a highway for barges," said Debbie Neustadt of Des Moines, who volunteers for the Sierra Club . The scope of the restructured study has been broadened beyond surveying simply navigation needs to also include ecological and floodplain factors as well. Previously, the Corps was trying to come up with a single forecast of navigational needs by 2050. An interim report is due this July; a draft feasibility study is due in the winter of 2004. The need for a speedy conclusion was a common theme among those who want to see locks expanded. Some environmentalists, however, are worried that the time frame may be too aggressive. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - To get off the IOWA-TOPICS list, send any message to: [log in to unmask]
