L-177A Humboldt Hill Valve Station - Gas Distribution Station in Eureka, California

L-177A Humboldt Hill Valve Station is a gas distribution facility located at 7167 Linda Rd, Eureka, California, within Humboldt County. The station is part of the natural gas distribution infrastructure serving the region, operating under the regulatory oversight of the US Pipeline and Hazardous Materials Safety Administration (PHMSA) and in compliance with DOT 49 CFR Part 192. As a gas distribution station, this facility regulates and controls the flow of natural gas from high-pressure transmission lines to lower-pressure distribution networks that serve residential, commercial, and industrial customers. The station's operational status is active, and it plays a key role in maintaining safe and reliable gas service in the Eureka area. The facility is situated in a region with moderate seismic activity, which is a relevant risk factor for gas infrastructure. Humboldt County's coastal location also exposes the station to potential climate hazards such as storms and flooding. The station's design and maintenance are subject to PHMSA regulations that address these environmental risks.

The facility is located in a seismically active region near the Pacific coast, which poses risks of ground movement and flooding. Local regulations require gas distribution stations to incorporate seismic shut-off valves and corrosion protection measures. The surrounding area includes mixed residential and rural land use, with proximity to Humboldt Bay and sensitive coastal ecosystems.
