The Times-PicayuneSt. Bernard Parish officials on Friday announced a two-pronged effort to combat the potential spread of oil into parish marshes.
A BP subcontractor on Wednesday began driving two parallel rows of 60-foot, 8-inch pilings some 500 feet apart off the coast, according to a parish news release. Once the pilings are driven and stable, boom will be connected to them, the release said.
The pilings with the boom are being put into place starting at the northeast corner of St. Bernard Parish marshes and will extend down the eastern shores of St. Bernard. Three to four miles of the project are complete, one to two miles out into Breton Sound, the parish said. Three jack-up barges are stationed in the area to supply pilings and boom.
