A Pacific Gas & Electric crew was at work in American Canyon on Tuesday morning replacing a section of 2-inch natural gas line at 159 Donaldson Way after a routine survey detected a small gas leak.
Brittany McKannay, PG&E spokesperson, said repairs would be completed Tuesday.
PG&E crews walk “every foot” of gas lines throughout the utility’s service area over a five-year period using equipment “capable of detecting very, very small amounts of gas,” McKannay said.
McKannay said there are many possible causes of leaks, including the age of the line, plant roots and excavation. She said anyone planning on digging on their property for any reason should take advantage of PG&E’s free underground service alert.
Contractors or homeowners should call 811 between 6 a.m. and 7 p.m., Monday through Friday, except holidays. Utilities then have two business days to locate and mark underground lines.
A crew will mark gas lines and underground power lines with yellow and red paint on surface streets and sidewalks.
Other utilities — telephone and water companies — mark their own services.
April is National Safe Digging Month, a reminder to the public to call 811 before digging.
