PG&E regularly patrols and conducts leak surveys on all of our pipelines. We try to identify signs of damage, soil erosion and other concerns that can affect the safety of the line. We also use cathodic protection systems to prevent corrosion. We follow even stricter safety standards on our larger diameter transmission pipelines.
