The Wyoming Department of Environmental Quality monitors and collects actual emissions data in accordance with federal regulations. Inventory data is uploaded to the appropriate database after all reporting facilities have submitted data to the AQD and that information has been reviewed. Emissions data may be updated when new information is received.
The AQD placed a Query Wizard into operation on July 1, 2014. This tool allows internal and external users to query the AQD’s two actual emissions databases. The WISE View database contains both Major and Minor point source actual emissions on a facility-by-facility, source-by-source, and pollutant-by-pollutant basis. The OGER database contains actual emissions associated with oil and gas production site operations on a well-by-well, source-by-source, and pollutant-by-pollutant basis.
To access the Query Wizard, please click here.
The other files available below also contain actual emission data and are current as of the date posted. The most recent emissions data is made available by the Query Wizard described above. Please contact the AQD’s Emissions Inventory & Regional Haze Supervisor for inquiries regarding emissions data.

Actual emissions inventories and production information is required of both major and minor, oil and gas sources in the Upper Green River Basin (UGRB) in support of efforts to reduce elevated ozone levels in the area. This information is collected on an annual basis.
Annual emissions inventories for the previous year will be due no later than April 30th of the current year.
Winter time emissions inventories (covering operations during February 1st – March 31st) will be due no later than June 30th of the current year.
Facilities with associated American Petroleum Institute (API) number (i.e. production sites, water injection wells, tank batteries, etc.) should be reported using one of three excel “Production Equipment Inventory” forms available below. These forms are identical in nature except that they allow the user to report more or less facilities.
All other facilities (i.e. compressor stations, gas processing facilities, water injection facilities, etc.) should be reported using one of two “Compressor Station and Pipeline Emissions Inventory” forms available below. These forms are identical in nature except that they allow the user to report more or less facilities.
The “Emission Factor Groups” Excel file available below can be used to determine which emission factor group oil and gas facilities belong to. The AQD has developed 55 different field and formation specific emission factor groups. Emission factors have been generated for roughly 18 of the 55 groups. Within this Excel file is a pivot table designed to provide a list of wells by operator that are in each emission factor group. Further instructions can be found on the “Instructions” tab of this Excel file.
Instructional .pdf files for completing and uploading emissions inventory forms can also be downloaded below. For questions concerning whether a fcaility is located within the UGRB designation area, please contact Tyler Ward at 307-777-7872 or tyler.ward@wyo.gov and provide a legal description (lat/long coordinates) of the location.
Please note that the Excel forms available below must be completed using Microsoft Excel 2007 or a newer version of this software. Also, please be aware that the files below can exceed 5 MB in size!
