Four Corners Pipe Line - Danby: Oil Pipeline Pump Station in Essex, California

Four Corners Pipe Line - Danby is an operational oil pipeline facility located in Essex, San Bernardino County, California. As a pump station on a major crude oil pipeline, it plays a key role in moving petroleum products across the southwestern United States. The facility is part of a larger pipeline network that connects production areas to refineries and distribution hubs. The facility operates under the regulatory oversight of the US Pipeline and Hazardous Materials Safety Administration (PHMSA) and complies with 49 CFR Part 195 for hazardous liquid pipelines. Typical pump stations like this one are equipped with centrifugal pumps, valves, and metering systems to maintain flow and pressure. The pipeline's age and cathodic protection systems are critical for integrity management, though specific details are not publicly available. This pump station supports the regional energy infrastructure by ensuring reliable crude oil transportation. Its location in the Mojave Desert near Interstate 40 provides strategic access to western markets. The facility's operational status contributes to the stability of fuel supply for California and neighboring states, highlighting its importance in the national pipeline grid.

The facility is situated in the Mojave Desert, an arid region with sensitive ecosystems and limited water resources. Pipeline operations in such areas require careful management to prevent spills that could impact desert soils and groundwater. Proximity to populated areas and waterways is minimal, but the transport of crude oil poses inherent risks. Cathodic protection and regular inspections are essential to mitigate corrosion-related leaks.
