With a little help from public and private sponsors, a large California farming company is replacing 12 of its diesel-powered rigs with models powered by liquified natural gas (LNG).

Located in Coalinga, CA near the intersections of Interstate 5 and State Highway 198, Harris Ranch is the first of three truck fleets in the San Joaquin Valley to implement their portion of the San Joaquin Valley Clean Corridor Project (CCP).
The company will run 12 Freightliner tractors equipped with the Caterpillar/Clean Air Partners (CAP) C-12, 425 hp dual-fuel LNG engine. The trucks will refuel at a new LNG fueling station located along the I-5. The station is open to the public and provides a strategic refueling site for LNG trucks traveling between Northern and Southern California.
The clean-fuel tractors will be delivering agricultural products throughout the San Joaquin Valley. They replace diesel units that averaged 86,700 miles per year and consumed 13,500 gallons of diesel fuel annually.
The new LNG tractors are said to reduce 21,024 pounds of particulate matter (PM10) and nitrous oxide (NOx) emissions per year. Using natural gas instead of diesel fuel is said to save 3 cents a mile at current prices.
Harris Ranch is paying $1.1 million towards the trucks and fueling station. The other $832,000 came from the Petroleum Violation Escrow Account and the Department of Energy’s Sustainable Energy Program ($400,000); the San Joaquin Valley Unified Air Quality Management District ($432,000) and Pacific Gas & Electric ($50,000).
The San Joaquin Valley Clean Corridor Project is a joint effort between The San Joaquin Valley Clean Air Transportation (CAT) Coalition and the Interstate Clean Transportation Corridor (ICTC) Project.
Their goals are to:
 Develop three publicly-accessible natural gas fueling stations.
 Deploy up to 60 clean-burning LNG trucks in three Central Valley fleets that have agreed to participate if the project is cost-effective.
 Displace over 1 million gallons of diesel annually.
The ICTC has a much broader mandate to building an alternative fuel infrastructure across the U.S. Phase One, a triangular corridor expected to link Los Angeles, the Bay Area, Las Vegas and Salt Lake City, is an interlocking series of refueling stations and facilities along the I-80, I-5, I-10, CA 99 and the I-15 highways.
