An Energy Transfer Partners subsidiary on Monday appealed a ruling by a federal judge in Louisiana that halted construction on a portion of its Bayou Bridge crude oil pipeline, according to court documents. 

The motion came after U.S. District Judge Shelly Dick on Friday issued a preliminary injunction revoking a needed permit for the pipeline, which is already under construction.

Environmental groups and local fisherman have opposed the line, citing concerns about the environment and local economy. A portion of the pipeline would run through the Atchafalaya Basin, a nearly 1 million acre wetland in southern Louisiana that is a critical component of the state’s commercial fishing industry and flood protection system. 

Representatives from Energy Transfer Partners did not respond to a request for comment.
