2010 Expansion

The 2010 Expansion Project increased the amount of natural gas transported on the Kern River Gas Transmission Company system by approximately 145,000 dekatherms or approximately 145 million cubic feet per day.  

New Facilities 

The Kern River 2010 Expansion Project consisted of primarily aboveground facilities. The company did not add any new mainline pipelines as part of the expansion. The expansion's aboveground work included installing additional compression and modifications at existing stations. Kern River confined the expansion activities at the two existing compressor stations in Wyoming to the areas within the fenced facilities. The project also included the installation of additional measurement equipment at existing meter stations in Wyoming and California. Kern River installed additional cathodic test posts on the right of way in highly populated areas for monitoring purposes. 

Kern River sought approval from the Pipeline and Hazardous Materials Safety Administration, an agency of the U.S. Department of Transportation, to increase the pipeline operating pressure. By increasing the maximum allowable operating pressure of our system, Kern River can safely transport additional natural gas through existing facilities, minimizing disruption and impact to the environment, landowners and neighbors near the pipeline right of way. The expansion increased the existing MAOP on the pipeline from 1,200 pounds per square inch to 1,333 psi, and at the compressor and meter stations from 1,250 psi to 1,350 psi.
