To successfully operate our petroleum refining facilities, we are required to expend significant amounts for capital outlays and operating expenditures. We may incur significant costs to comply with new or changing environmental, health and safety laws and regulations, and face potential exposure for environmental matters. Competition in the refining and marketing industry is intense, and an increase in competition in the markets in which we sell our products could adversely affect our earnings and profitability. We may not be able to retain existing customers or acquire new customers. A material decrease in the supply of crude oil available to our refineries could significantly reduce our production levels. The potential operation of new refined product transportation pipelines or proration of existing pipelines could impact the supply of refined products to our existing markets, including El Paso, Albuquerque and Phoenix. We depend upon HEP for a substantial portion of the distribution network for our refined products and we own a significant equity interest in HEP. Our operations are subject to operational hazards and unforeseen interruptions for which we may not be adequately insured. If we lose any of our key personnel, our ability to manage our business and continue our growth could be negatively impacted.
