SALISBURY, Md.— The pipeline grows. The Salisbury City Council heard the latest update Monday evening on a controversial natural gas pipeline set to extend service to Somerset County. The Del-Mar Energy Pathway pipeline will extend natural gas service to Eastern Correctional Institution and the University of Maryland Eastern Shore, as both anchors look to transition off more polluting fuels. Chesapeake Utilities Corp. got the unanimous green light from the Maryland Board of Public Works in January for the $34 million project, which will add nearly seven miles of 10-inch-diameter gas pipeline from Delaware, through Wicomico County and into Somerset County. "Residents and businesses along the line will soon have the choice to use environmentally beneficial and less expensive natural gas service," wrote Justin Mulcahy, spokesman for Chesapeake Utilities Corp., in a statement that month, "something elected officials and community members have advocated for more than two decades."
