Beginning Monday, April 26, PG&E will conduct aerial patrols of gas transmission pipelines in Sonoma County and the North Bay, with helicopters flying as low as 300 to 500 feet and a fixed-wing aircraft.
PG&E will also be patrolling lines in Vallejo, Marin and Napa counties.
The low-flying Lasen helicopter will inspect transmission lines through the end of the month. These flights are Monday through Sunday between the hours of 8 a.m. and 4 p.m., said PG&E in a press release.
If gas is detected, PG&E personnel are sent to the field to follow up, the company said. “The observer in each helicopter also uses a GPS-enabled tablet with mapping data to help identify safety concerns that would prohibit access to the pipeline.”
