Project Details

  • Operator: SDG&E[2]
  • Parent Company: Sempra Energy[1]
  • Capacity: 630 million cubic feet per day[2]
  • Length: 50 miles / 80.5 km[1]
  • Diameter: 16-inches[1]
  • Status: Operating[1]
  • Start Year: 1949[2]

Background

Built in 1949, the line provides only about 10% of capacity for the San Diego area, but remains the only source of natural gas supply for about 150,000 customers in the eastern Fallbrook, Valley Center, Escondido, Rancho Bernardo, Rancho Peñasquitos, Poway, Scripps Ranch, Kearny Mesa and Serra Mesa areas of San Diego, California, USA.[1]

Replacement Project

SDG&E, working with fellow Sempra Energy affiliate Southern California Gas, plans to replace 37 miles of Line 1600 that runs through urban and suburban areas and hydrotest the remaining 13 miles located in more rural areas. The project will be done in 19 segments. Construction on the first segment, a 2.44-mile stretch on Midway Drive in Escondido, began in February 2020. The utility says the 71-year-old line is riddled with some defects known as “hook cracks” but questions have been raised about the cost of the project. The commission failed to pass a proposed decision that would have delayed work until the price tag was finalized. Instead, commissioners OK’d an alternative that allowed crews to start promptly while the final cost is sorted out. Four opposition groups have filed for a rehearing, saying that the project will use new rights-of-way that require an environmental assessment and the commission committed “a legal error” when it approved the Line 1600 replace and repair program.[1]
