Tons of rocks intended for a protective barrier against the oil spill are on Mississippi River barges in Pointe à la Hache, Louisiana. Lee Celano for The New York Times

Published: July 6, 2010 With oil hitting Barataria Bay, a vast estuary in southeast Louisiana that boasts one of the most productive fisheries in the country, local parish officials hatched a plan in May to save the fragile ecosystem: they would build rock dikes across several major tidal inlets between the bay and the Gulf of Mexico to block and then capture the oil. Gov. Bobby Jindal of Louisiana supported the plan, and BP agreed to pay for the project, estimated to cost $30 million. By early June, about 100,000 tons of rock began being loaded onto barges on the Mississippi River for transport to the coast. But over the weekend, the Army Corps of Engineers denied a permit for the project, citing environmental concerns, in particular the potential for the rock barriers to cause widespread erosion and the breaching of Barataria Bay’s existing barrier islands. The ruling echoed the sentiments of independent experts on coastal wetlands who had strongly objected to the plan. Now the rock sits on 75 barges on the Mississippi River with no immediate use. As the Gulf oil spill enters its third month, Louisiana officials have grown increasingly enamored of large-scale engineering projects, like sand berms and rock walls, to keep the oil off their coast. But these projects, which demand the swift restructuring of eastern Louisiana’s dynamic and fragile coast, have brought the desires of state and local officials into sharp conflict not only with a complicated federal bureaucracy charged with protecting wetlands and estuaries, but also with an experienced and highly vocal community of local coastal scientists. “They’re just sitting back criticizing,” said Deano Bonano, the emergency-preparedness director for Jefferson Parish, which borders Barataria Bay. “Where are they when it comes to protecting this bay?” In a speech on Tuesday in New Orleans, Mr. Jindal said: “No one can convince us that rocks in the water are more dangerous than oil. That is absolutely ridiculous. The only people who believe that are the bureaucrats in Washington, D.C., who can’t see the oil, smell the oil or touch the oil.” The scientists insist the rock plan was misguided. “There was very strong scientific backing for not doing this,” said Denise Reed, a wetlands specialist and director of the Pontchartrain Institute for Environmental Sciences in New Orleans. “This could really devastate our barrier shoreline, our first line of defense.” …
