The oil industry is subject to a range of federal and local laws and regulations that concern environmental protection, including generation, storage, transportation, transportation, and discharge of materials into the environment. This trend is likely to continue, with stricter regulations requiring permits and other authorizations for construction and other activities, as well as restrictions on access to seismic acquisition, drilling, and other activities on lands in wilderness and other protected areas, which can result in significant liabilities for pollution and reclamation of certain lands.
