Chevron has been given approval by US government agencies to begin repair work on a damaged Louisiana oil line that leaked oil into a wildlife refuge.
A Chevron spokesperson was quoted by Reuters as saying agency approvals were necessary to start work on the Chevron pipeline because of its location.
"The completion of the risk assessment, as well as any integrity testing, will be required prior to restoring Cypress ten-inch to full service," the Chevron spokes person said.
The line leak was discovered after a contractor for ExxonMobil anchored a barge near the pipeline that had leaked about 18,000 gallons of Heavy Louisiana Sweet oil near the mouth of the Mississippi River, according to Reuters.
The pipeline is owned by Cypress Pipe Line, a joint venture between Chevron and BP and operated by Chevron Pipe Line.
