UGI Susquehanna River Pipeline Crossing

EEI performed a geotechnical investigation for the construction of a new 12-inch-diameter natural gas pipeline under the Susquehanna River for UGI. The proposed pipeline will extend approximately 4,100 feet from the Borough of Steelton, Dauphin County, Pennsylvania, to the Defense Logistics Agency (DLA) Distribution Susquehanna Facility, York County. Approximately 2,300 feet will cross under the Susquehanna River bed and rail lines located on the east and west banks of the river. The investigation comprised three land borings, three water borings, a laboratory testing program, and a geotechnical report that also included construction recommendations. The water borings were completed utilizing an ATV-mounted drill rig capable of drilling and maneuvering in aquatic conditions.
