PG&E is conducting routine low-level helicopter patrols to inspect gas transmission and distribution lines in Marin County, as part of its six-month leak survey and maintenance program.
A helicopter will fly over parts of Wolfback Ridge and San Rafael through April 30. Flights will be coming and going from the Hayward Executive Airport, the Napa County Airport and the Charles M. Schulz Sonoma County Airport.
PG&E patrols remote gas lines, which are often located in rural areas, by helicopter as part of its continuing effort to ensure the safety and reliability of its natural gas system. If issues or obstructions are identified, it is possible helicopters may need to fly at a lower altitude for additional inspections.
