Napa fire and police personnel cordoned off a one-block area for about an hour Saturday night around the Chevron at 2008 Redwood Road after a reported leak of compressed natural gas at the service station.
Napa Fire Battalion Chief Steve Brassfield said the gas station, an adjoining shopping center and a nearby 7-Eleven convenience store were evacuated after the call to dispatchers came in at 9:51 p.m.
After using monitoring devices to determine the extent to which the gas had spread, firefighters closed Redwood from Solano Avenue west to Carol Drive, but no residential evacuation was ordered, according to Brassfield. He said the lack of strong wind likely kept the leakage within a small area and prevented a more widespread closure. The nearby Highway 29 interchange to Redwood and Trancas Street remained open during the shutdown.
Police also were sent to the Napa Valley Marriott and Spa just north of that intersection, but no one there was evacuated, police said.
The owner of the Chevron, Tim Cardoza, said there are six above-ground containers of the gas at the station. The fuel is dispensed to various commercial vehicles, including Napa public transit buses, he said.
Police reopened Redwood Road shortly after 11 p.m.
The cause of the natural gas release remained under investigation early Sunday. Cardoza, the station owner, said a compressing unit apparently failed, but that safety equipment prevented a buildup of gas pressure and that Napa Fire closed off the system’s supply. Natural gas service at the Chevron would be suspended while repairs were made, he said.
