Occidental's operations may be subject to new or amended laws and regulations, as well as new or different interpretations of existing laws and regulations, such as those pertaining to drilling, flaring, and production techniques, such as hydraulic fracturing and acidization, with respect to royalty rates, import, export, and use of raw materials, equipment, and resources, as well as increased use of land water, air emissions, water recycling, and safety measures, all of which may lead to increased costs or demand for Occidental's operations.
