HollyFrontier Corporation Provides Update on Fourth Quarter Refinery Maintenance

DALLAS--(BUSINESS WIRE)-- HollyFrontier Corporation (NYSE: HFC) today announced that planned fourth quarter maintenance on the El Dorado and Cheyenne Distillate Hydrotreating units and the Tulsa West Crude and Lubricants units was complete. During the quarter, the Tulsa refinery also experienced an unplanned shutdown of its Fluid Catalytic Cracking Unit (FCCU). Repairs have been completed and the FCCU has successfully restarted. Extreme weather conditions in New Mexico have also impacted crude rate at the Navajo Refinery due to crude availability constraints. As a result of the weather and both planned and unplanned maintenance, HollyFrontier Corporation expects crude oil throughput for the fourth quarter 2015 to average between 395,000 and 405,000 barrels per day.
