Oil and Gas
Oil and gas exploration and production activities are significant air pollution sources in the western United States. There is wide variation by basin, in terms of the types of wells and equipment operated and quantities of hydrocarbons produced, the number of wells to be maintained and to be newly drilled, the extraction practices and emission control technology applied in the drilling-completion-maintenance-production activities. Taxes on produced hydrocarbon resources fund state, tribal, and federal governments, and the commodity prices are subject to wide variation affecting both existing production and emissions, as well as development of new and/or replacement wells.
With the oil and gas sector continuing to experience rapid change and innovation over time, air regulatory agencies are responding to health and welfare issues under the federal Clean Air Act as well as through state and tribal authorities. These include jurisdiction-wide emissions reporting and control requirements, linked to efforts to address local issues and impacts. In the WESTAR-WRAP region, oil and gas exploration and production activity is concentrated in California, Alaska, and the Intermountain Region, with emissions management by states, tribes, and EPA. The produced hydrocarbons are transported with various methods for further processing and are then used in dozens or hundreds of products. The use of produced hydrocarbons for power, industrial, and commercial applications is ubiquitous in the U.S. and other well-developed economies.
