PG&E Silverado Substation - Gas Distribution Station in Saint Helena, California

PG&E Silverado Substation is a gas distribution station located at 465 La Fata Street in Saint Helena, California. It operates within the Napa County area, serving residential and commercial customers in the region. The facility is part of Pacific Gas and Electric Company's extensive natural gas infrastructure, which supplies energy to millions of customers across Northern California. As a gas distribution station, this facility reduces pressure from high-pressure transmission pipelines to lower pressures suitable for local distribution. It is subject to PHMSA pipeline safety regulations and DOT 49 CFR Part 192, which govern the design, construction, and operation of gas distribution systems. The station likely includes metering, pressure regulation, and odorization equipment to ensure safe and reliable gas delivery. The Silverado Substation plays a key role in the local energy grid, supporting the Napa Valley community with natural gas for heating, cooking, and industrial uses. Its location in a seismically active region means it is designed to withstand earthquakes, with safety features such as automatic shut-off valves and seismic monitoring. The facility contributes to the resilience of the regional gas infrastructure.

The station is situated in Saint Helena, a town in the Napa Valley wine region, which is prone to seismic activity due to nearby fault lines. Gas distribution stations in such areas require robust seismic safety measures to prevent leaks and ruptures. The facility's proximity to populated areas and vineyards necessitates strict adherence to safety protocols to minimize environmental risks, including methane leakage and fire hazards.
