During the installation of new gas lines by Pacific Gas and Electric Company (PG&E), some private sewer laterals may have been pierced or completely bored through - known as cross bore. Underground Service Alert does not typically mark private sewer laterals and as a result, cross bores may go undetected, and if damaged create a potentially hazardous situation. For gas line cross bore information, visit  PG&E's website. A review of a closed-circuit television (CCTV) inspection should also include looking for evidence of a cross bore. If you suspect a gas line cross bore, call  PG&E at 800-743-5000. If you suspect a gas leak, warn inhabitants, evacuate the area and call 911 and PG&E at 800-743-5000.
