At a length of 86 miles (138 km), the North Baja Pipeline System delivers West Texan and Rocky Mountain natural gas from Arizona to California and Mexico.

Stretching 305 miles (491 km) from Oregon across California and into Nevada, the Tuscarora pipeline delivers natural gas from the Western Canada Sedimentary Supply, the Rocky Mountains and US basins to communities in California and Nevada.
