City officials in San Carlos, Calif. have declared a State of Emergency after a series of internal PG&E e-mails sparked safety concerns over a natural gas line that runs through the city. Issues with the gas line include certain sections made up of a "thin wall" pipe made in 1929 and external corrosion with fatigue cracks on the pipe. City leaders on Friday also requested PG&E shut down the pipeline until a hearing could be conducted with CPUC to address the issue. PG&E declined the request, according to city officials. The city on Friday night obtained a temporary injunction against PG&E in San Mateo County Superior Court requiring PG&E to immediately shut off service to pipeline 147. A hearing is scheduled for Oct. 24.
