Emission Inventory Forms
The Wyoming Department of Environmental Quality (DEQ), Air Quality Division (AQD), collects and manages data on air pollution emissions throughout the state. There are several different emission inventory efforts. Click on the links below to get further information and forms for each inventory:
12/14/12 Calculation & Reporting VOC and Formaldehyde Emissions From Engines: A review of EPA test methods and the NSPS for engines reports VOC emissions as propane for engines. Test methods and EPA regulations indicate that formaldehyde emissions are not included in the VOC component. For determining actual "total" VOC emissions from engines on all inventories, VOC emissions must be converted back to total carbon emissions with formaldehyde emissions added in as described in this memo. Please contact either Brian Bohlmann at 307-777-6993 or firstname.lastname@example.org, or Mark Gagen at 307-777-7351 or email@example.com for questions concerning this memo.
Major (Title V) Emission Inventory: Facilities subject to the Title V Operating Permit Program are required to submit annual inventories to the Division of their actual emissions.
Triennial Minor Source Emission Inventory: In accordance with 40 CFR Part 51, Subpart A, states are required to report total state-wide emissions to the United States Environmental Protection Agency (EPA) every three years. The Division requires each minor source in Wyoming to submit actual emission data for this effort. Calendar year 2011 data is due to the Division by April 30, 2012.
Annual Sulfur Dioxide Inventory: Sources subject to the emissions trading program for SO2 under WAQSR Chapter 14, Section 3, for Regional Haze, are required to submit annual SO2 emission inventories.
Annual and Winter Upper Green River Basin Emission Inventories: Actual emissions inventories and production information is required of sources in the Upper Green River Basin in support of efforts to reduce elevated ozone levels in the area.
Information on emission inventory data reported to the Division is available on the Actual Emissions web page.
If you own/operate an oil and gas production site (which includes drilling, completion and workover activities) the inventory forms are available on the Oil and Gas Production Site Emission Inventory Forms web page. Please note that in order to complete these forms you must use Microsoft Excel 2007 or newer versions.
Once completed, upload the inventory information onto the Wyoming DEQ web server using the Web Upload Instructions provided.
