. Our Corpus Christi East and West Refineries are located on the Texas Gulf Coast along the
Corpus Christi Ship Channel. The East Refinery processes sour crude oil, and the West Refinery processes sweet crude oil, sour crude
oil, and residual fuel oil. In 2015, we completed construction and placed into service a new 70,000 BPD crude distillation unit in the
West Refinery. The feedstocks are delivered by tanker or barge via deepwater docking facilities along the Corpus Christi Ship Channel,
and West Texas or South Texas crude oil is delivered via pipelines. The refineries’ physical locations allow for the transfer of various
feedstocks and blending components between them. The refineries produce gasoline, aromatics, jet fuel, diesel, and asphalt. Truck
racks service local markets for gasoline, diesel, jet
