Honor Rancho Compressor Modernization Project

The Honor Rancho Storage Field has been operating safely and reliably since 1976. The modernization of the nearly 50-year-old infrastructure is required to comply with new South Coast Air Quality Management District (SCAQMD) air emissions requirements. In June 2022, SoCalGas submitted a Permit to Construct application for the Honor Rancho Compressor Modernization Project. The main purposes of the project are to:

Comply with SCAQMD Rules 1110.2/1100
Modernize the Honor Rancho Storage Field through the replacement of aging natural gas fueled compressors with a combination of new natural gas fueled and electric driven compressors and other innovative technology that will achieve significant reductions in nitrogen oxide (NOx) emissions
Enhance reliability by modernizing aging equipment and ancillary systems

Estimated 95% Reduction*

In Certain Smog - Forming Pollutants Potential Emissions

Compressors at Storage Facilities

Compressors provide the mechanical means to inject natural gas into underground storage reservoirs, playing a crucial role in the overall safe, reliable and affordable operation of SoCalGas’ natural gas system.

When customer demand on the gas system requires additional supply, valves and other equipment at SoCalGas’ storage fields can be activated to allow gas to flow from the natural gas storage reservoirs into SoCalGas’ transmission and distribution system.
