Thursday, December 30, 2010, 7:30 PM Louisiana’s coastline continues to be smeared with significant amounts of oil and oiled material from the BP Deepwater Horizon disaster, with cleanup teams struggling to remove as much as possible of the toxic material by the time migratory birds arrive at the end of February, said the program manager of the Shoreline Cleanup and Assessment Teams, which are working for BP and the federal government. There are 113 miles of Louisiana coastline under active cleanup, with another 55 miles awaiting approval to start the cleanup process, according to SCAT statistics. Teams have finished cleaning almost 72 miles to levels where oil is no longer observable or where no further treatment is necessary. But that’s not the whole story for the state’s coastline. According to SCAT statistics, there’s another 2,846 miles of beach and wetland areas where oil was once found but is no longer observable or is not treatable. Gary Hayward, the Newfields Environmental Planning and Compliance contractor who oversees the SCAT program, said that large area will be placed into a new “monitor and maintenance” category, once Louisiana state and local officials agree to the procedures to be used for that category. “With rare exceptions, most of the marshes still have a bathtub ring that we have all collectively decided we aren’t going to clean any more than we already have because we’d be doing more harm to the marshes than the oil is going to be doing to them,” Hayward said. The cleanup protocols for each state have been approved by state and local governments, federal agencies and BP, he said. Louisiana’s senior coastal official says the state is monitoring the cleanup, and remains concerned with end-of-year conclusions that the cleanup is almost complete. “The reality is we still have hundreds of miles of oiled shoreline today,” said Garret Graves, chairman of the Coastal Protection and Restoration Authority. “We still have oilings on a regular basis in areas of Jefferson and Plaquemines Parish, and there’s still a lot of oil buried back in the marshes where it was carried during high water events. “The threat is absolutely still there and the oil is absolutely still there,” he said. …
