HollyFrontier Expects Resolution to Previously Announced Refinery Waste Water Constraints at Sub Navajo Refinery

HollyFrontier Corporation HFC announced that it expects a resolution to the previously announced refinery waste water constraints at its subsidiary's Navajo Refinery by approximately the end of January 2014. In the interim, crude throughput at the Navajo Refinery is expected to be approximately 60,000 barrels per day. Based on HFC's current operational outlook, HFC's fourth quarter 2013 total crude throughput guidance is approximately 370,000 barrels per day, and HFC's first quarter total crude throughput is expected to be negatively impacted by approximately 10,000 barrels per day due to January constraints at the Navajo refinery.
