    Partly in response to last year’s deadly natural gas transmission line explosion near San Francisco, SDG&E has proposed a $600 million upgrade to be funded by ratepayers, according to a filing with regulators on Friday.

    The 10-year project would include a safety upgrade to major lines looping around the county, according to officials and the San Diego Union Tribune.

    About 102 miles of large-diameter pipelines, built in the 1950s, would be replaced during the two-phase project, the paper reported.

    The areas where the pipelines loop through include La Jolla, El Cajon, North Park, Mission Bay, National City and 54 miles stretching from Kearny Mesa north to Rainbow.

    SDG&E has been unable to locate construction or testing records for about 30 percent of its large-scale gas transmission lines, and has lowered the pressure of natural gas in those lines as a result, the U-T reported.
