Mountain Pass Lateral

Kern River Gas Transmission Company’s Mountain Pass lateral was built to provide 24,270 dekatherms per day of natural gas transmission capacity to Molycorp Minerals, LLC’s Mountain Pass rare earth mine for use in power generation and steam production. 

The Mountain Pass Lateral Project included construction of an approximately 8.6-mile, 8-inch-diameter pipeline extending from Kern River’s mainline. The project also included construction of a new tap assembly, pig launcher, pig receiver and meter station. Kern River made every effort to minimize the impact on the environment and landowners along the existing rights of way and worked closely with permitting agencies to ensure the project met regulatory requirements.
