A Sunoco Logistics Partners LP pipeline spilled about 1,300 barrels of gasoline into the Susquehanna River in Lancaster County, Pennsylvania, on Friday, according to local media.
The pipeline breach was caused by heavy flooding in Lycoming County, which lies in the north-central region of Pennsylvania.
The 8-inch (20-cm) pipeline began leaking in Gamble Township, Lycoming County, at about 3 a.m. on Friday, Lancaster Online reported, citing a statement from Sunoco Logistics. The line was reportedly shut down after detecting a drop in pressure.
Sunoco Logistics and the Pennsylvania Emergency Management Agency did not respond to requests for comment.
The report of the leak comes as the Standing Rock Sioux tribe and environmental activists have been protesting construction of the 1,100-mile (1,886-km) pipeline in North Dakota for several months saying it threatens water supply and sacred sites.
