* Water useage per barrel at the North Pole refinery is much lower than the other two refineries due to its configuration.
There are two studies that help put FHR's refinery water use in perspective. A report, Texas Industrial Water Usage Survey, Pequod Associates, Inc. and TWDB, Austin, Texas, August 1993, indicates that Corpus Christi-area refineries used an average of 46 gallons of water per barrel of crude processed, compared to the state average of 100 gallons per barrel refined. A U.S. Department of Energy study in 1998 indicates that California refineries used a range of 20 to 60 gallons of water per barrel refined.
* Reported in gallons-per-pound of product produced.
