Pipeline Expansion and Compressor Station Upgrade


Chester Co., PA and New Castle Co., DE


This project included approximately 5.4 miles of 16-inch diameter natural gas pipeline looping in Chester County, Pennsylvania and the expansion of a compressor station in New Castle County, Delaware. The looping was divided into two separate segments and the alignments mostly followed existing facility rights-of-way.

GTA provided natural resource evaluations and federal and state permitting services for this utility alignment project. GTA coordinated with the United States Army Corps of Engineers (USACE), Pennsylvania Department of Environmental Protection (PADEP), United States Fish and Wildlife Service (USFWS), Pennsylvania Fish and Boat Commission (PFBC), Pennsylvania Department of Conservation and Natural Resources (DCNR), Pennsylvania Game Commission (PGC), Delaware River Basin Commission (DRBC), Pennsylvania Historical and Museum Commission (PHMC), National Park Service (NPS), Delaware Department of Natural Resources and Environmental Control (DNREC) Wetlands and Subaqueous Lands Section and the Natural Heritage and Endangered Species Program, and the Delaware State Historic Preservation Office ( DE SHPO). GTA prepared Environmental Resource Reports for submittal to the FERC, and pursued and obtained a FERC Certificate of Public Convenience and Necessity.  Additionally, GTA submitted a Joint Permit Application to the PADEP and the USACE, and obtained a State Water Obstruction and Encroachment Permit and a Pennsylvania State Programmatic General Permit.  GTA obtained Jurisdictional Determinations from the DNREC Wetlands and Subaqueous Lands Section and the USACE for wetlands/waterways at the existing compressor station site; provided FERC Environmental Inspector Training; and served as Environmental Inspector for construction on a portion of the project. GTA also managed Cultural Resource Services and Threatened and Endangered Species consultations through subconsultants on behalf of the client and obtained concurrence letters from the Pennsylvania and Delaware State Historic Preservation Offices, and the USFWS, PFBC, DCNR, and DNREC.
