ONQUEST COMPLETES PROJECT FOR CLEAN ENERGY LNG FACILITY IN BORON

Process Firm Completes Substantial EPC Project for Nation's Largest LNG Company

Los Angeles, CA (April 30, 2010) San Dimas, Calif.-based OnQuest, Inc., a leader in furnace and process technologies for the petrochemical industry, has completed project work at Clean Energy California's groundbreaking natural gas liquefaction and distribution facility in Boron, CA.

Clean Energy's Boron facility produces up to 160,000 gallons of liquid natural gas (LNG) per day using two liquefaction trains, with nominal annual production at approximately 60 million gallons. OnQuest's design allows for a third train to be installed as needed, to produce up to 240,000 gallons of LNG per day.

Construction was initiated in August 2007 and OnQuest brought the first LNG train on-stream in October 2008. The new plant began delivering fuel to customers in November 2008.

OnQuest won the engineering project in March of 2006 in conjunction with its sister firm, ENR 400 construction company, ARB Inc. Together, the two companies had a range of responsibilities for the project, including engineering design and construction of water, gas and power utilities, feed-gas treatment and the plant control system. The plant design includes boil-off and flash gas recovery, loading and unloading facilities, and return gas metering, all controlled by a distributed control system.

The Boron facility also has a 1.5-million-gallon LNG storage tank for reserves, to allow for uninterrupted supply during routine maintenance.

Clean Energy is the largest provider of natural gas for transportation in North America and is a leader in environmentally responsible transportation fuels.
