Statewide Oil and Gas Emissions Inventory - Utah Department of Environmental Quality

Utah is home to a wealth of natural resources, particularly in the oil and gas sector. Responsible production of these resources is essential to preserving our state’s beautiful natural landscapes and to prioritizing the public health of our citizens. Oil and gas operators will find web resources here to help them abide by Division of Air Quality regulations. Tools for completing oil and gas emissions inventory workbooks, registering facilities, and other supplementary information can be found below. Oil and gas emissions inventory data can be accessed on the Statewide Emissions Inventories page.

2014 Air Agencies Oil and Gas Emissions Inventory: Uinta Basin

For almost a decade the 2006 Western Regional Air Partnership (WRAP) Phase III oil and gas emissions inventories were relied on for the Uinta Basin (Basin), the main oil and gas producing region in Utah. Although these inventories were projected forward using up-to-date annual production and drilling activity data from the region, the inventories still lacked the ability to capture the technological advancements that occurred over the period.

In 2013 Utah Division of Air Quality (UDAQ) started working to develop an up-to-date and improved oil and gas emissions inventory for the Basin. This process involved the cooperation of various stakeholders, including operators from the Uinta Basin, Western Energy Alliance (WEA), Environmental Protection Agency (EPA), Bureau of Land Management (BLM), and the Ute Tribe.

In 2015, an emissions inventory workbook and request for completion was sent to each operator in the Uinta Basin active in 2014. In 2016 the data was compiled into a 2014 Uinta Basin oil and gas emissions inventory database.

In addition to the collected inventory UDAQ has worked to determine and begin collecting supplemental data needed in addition to the collected inventory to create a truly comprehensive 2014 inventory, including additional equipment categories not addressed through the workbook request.

Oil & Gas Emissions Inventories

Oil and gas inventories are based on data submitted by various oil & gas sources throughout the state. The inventory is primarily comprised of “… emissions at oil & gas facilities with Standard Industrial Classification codes in the major group 13 that have uncontrolled actual emissions greater than one ton per year for any single pollutant including: PM10, PM2.5, NOx, SOx, CO, or VOC. These sources include, but are not limited to, industries involved in oil and natural gas exploration, production, and transmission operations; well production facilities; natural gas compressor stations; and natural gas processing plants and commercial oil and gas disposal wells, ponds and sites.” (R307-150)
