SAN FRANCISCO, Dec. 18, 2012 /PRNewswire/ -- Building on its commitment to natural gas pipeline safety, Pacific Gas and Electric Company (PG&E) announced that it validated the safe operating pressure of an additional 194 miles of natural gas transmission pipeline in 2012, through hydrostatic pressure testing and rigorous records validation. These activities were completed in areas throughout Northern and Central California as part of PG&E's Pipeline Safety Enhancement Program (PSEP) and through regularly scheduled projects to verify the integrity of natural gas transmission lines—the large-diameter pipes that carry gas across long distances. Since PSEP projects launched in 2011, PG&E has successfully tested a total of 409 miles of gas transmission pipeline. PG&E also started construction on a state-of-the-art gas control center at its new Gas Operations headquarters at Bishop Ranch in San Ramon, Calif. The center will serve as a central location from which PG&E will monitor the safe and reliable operation of its 6,700 miles of transmission pipeline and 42,000 miles of smaller-diameter distribution mains. Completion of the gas control center is expected in Q2 2013. "There is nothing more important than working to make our natural gas system safer in the communities we serve. We've made tremendous progress, but the work we've done is just the beginning," said Nick Stavropoulos, executive vice president of Gas Operations for PG&E. "Our goal is to operate the safest and most reliable natural gas system in the country." Hydrostatic pressure testing is one of several important measures PG&E is taking to enhance the safety and strength of its natural gas system. Through the end of 2014, phase one of the PSEP program, the utility plans to pressure test or validate 783 miles of gas transmission pipeline, replace 185 miles of pipeline, automate more than 220 valves, and upgrade nearly 200 miles of pipeline to accommodate advanced in-line inspection tools known as "smart pigs."
