Background Information on Natural Gas Pipeline Safety in San Carlos
At a PG&E community meeting on November 23rd, 2010, San Carlans posed some difficult questions and requested information about the age, depth, maintenance and inspection of the two natural gas transmission pipelines that cross through San Carlos. On December 15th, 2010, PG&E responded in an extensive, detailed 9-page letter (PDF, 2 MB), addressed to late Mayor Omar Ahmad. It states that segments of Line 101, which runs under Old County Road, Commercial Street and Industrial Road, were installed in 1987, 1988, and 1995. Segments of Line 147, which runs under Brittan Avenue, Eaton Park, Loma Road, La Mesa Drive, Pebble Drive and Crestview Drive, were installed in 1947, 1957, 1967, 1987 and 1991.
