Oil and gas production in Wyoming is well regulated. Flaring must incorporate Best Available Control Technology (BACT), including enclosed, smokeless combustion devices or flares. These flares must reduce the mass content of VOC and total HAP emissions by at least 98 percent.
VOC and HAP emissions from flaring should be based upon the guaranteed DRE of the flare. Reported flared gases should include pilot gas with heat content and flared gas with average estimated heat content. Gases normally burned by flares in Wyoming have more than 900 BTU/scf.
To comply with Wyoming Department of Environmental Quality Air Quality Rules, flaring or venting must be reported monthly and include duration and total estimated volume of gas, circumstances that resulted in flared gas, identification of whether gas was vented or flared, identification of whether gas volume is based on metered flow or other measurement and a compositional analysis of the gas.
Venting or flaring is authorized in the cases of emergencies or upset conditions, and for safety purposes during necessary maintenance or upgrades. Additionally, production tests and well purging and evaluation tests are permissible for flaring.
