An 8-inch natural gas pipeline crosses an unnamed creek in Tioga County, Pennsylvania in a 50-foot wide right-of-way. The creek bed and banks are composed of clay and rock. The right descending bank of the creek has been eroded due to flooding creating an 8-foot pipeline exposure.
A 30-inch diameter natural gas transmission pipeline crosses at the confluence of the White River and the East Fork of the White River. The White River had laterally migrated and the right, descending, high bank eroded to expose the pipeline.
