Refining Segment

Founded: 2005

Operations: Tyler, Texas and El Dorado, Arkansas

Two inland refineries with a combined production capacity of more than 140,000 barrels per day. Our refining segment is comprised of a 60,000 barrel per day refinery in Tyler, Texas and an 80,000 barrel per day refinery in El Dorado, Arkansas.

The 9.5 complexity Tyler refinery processes mainly locally sourced light, sweet crude oils, including West Texas Intermediate (WTI) and other WTI-linked crudes. Tyler produces a full range of refined products, including gasoline, diesel, jet fuels, liquefied petroleum gas and natural gas liquids. Historically, more than 90% of Tyler's production slate has been comprised of light, high-value products such as gasoline and distillate fuels.

The 9.0 complexity El Dorado refinery processes a combination of WTI-linked, domestic offshore and foreign crude oils. El Dorado produces a wide range of refined products, from multiple grades of gasoline and ultra-low sulfur diesel fuels, LPG's, refinery grade propylene and a variety of asphalt products, including polymer modified asphalt. El Dorado produces both low-sulfur gasoline and ultra-low sulfur diesel fuel, in compliance with current "clean fuels" standards.

Broad-based product distribution footprint. The Tyler refinery is the only supplier of a full range of refined petroleum products within a radius of approximately 100 miles. Historically, Tyler has sold the bulk of its production volumes through a multi-lane rack system located on the periphery of the refinery. Through this rack system, Tyler sells products to wholesale customers in the regional market.

The El Dorado refinery sells refined products through commercial contracts and through exchange agreements. The refinery primarily serves markets in Arkansas, Tennessee, and markets along the Enterprise Products Pipeline system which runs from the Gulf Coast into the Midwest. The refinery also supplies products to exchange partners on the Magellan and Colonial pipeline systems.

Both refineries have benefited from significant capital investment. The Tyler and El Dorado refineries have been managed to maximize safety, reliability and environmental compliance. Since 2007, more than $800 million has been invested in the Tyler and El Dorado refineries to complete a combination of regulatory ("clean fuels") compliance, in addition to a series of discretionary and maintenance related projects designed to enhance the efficiency of operations. During 2009, both the Tyler refinery and the El Dorado completed major maintenance turnaround activities.
