The Wyoming Department of Environmental Quality (WYDEQ) has requested that all production site operators develop and submit equipment inventories for their operations in Wyoming. The inventories will include emission units, control devices, and release points for surface equipment such as:

  • Tanks
  • Dehydration units
  • Separators
  • Heaters
  • Oil/Condensate truck loading
  • Fuel fired engines
  • Catalytic controls
  • Flares/combustors
  • Fugitive components (connectors, valves, flanges, etc.)
  • Gas-driven pneumatics
  • Completions
  • Blowdowns/venting

For any operations in existence prior to September 2014, when the WYDEQ first began using their current database system for air quality related facility information, collecting this information can represent a significant effort. (Operations permitted after September 2014 are already part of the agency's database.) WYDEQ has two options for submitting this information - use of the agency's online IMPACT (Inventory, Monitoring, Permitting and Compliance Tracking) system, or completing and submitting workbooks available from the WYDEQ. The agency prefers inventory submittals through IMPACT.

While this is a one-time effort, the level of detail required (including equipment sizes, maximum throughput/storage/usage levels, and much more) is substantial. The priority for the agency is to collect information on operations in the Upper Green River Basin (UGRB) in Southwest Wyoming. Companies with operations in the UGRB have been asked to submit information on those operations as soon as possible, to facilitate preparation of winter emission inventories for 2020. For the rest of the state, the WYDEQ is requesting facility information prior to preparation of the state-wide triennial minor source inventory due in 2021 but which will cover operations and emissions during 2020.

Trinity has been closely involved with implementing the IMPACT system since its inception and can offer tips, tricks, and practical advice for how to deal with this information request, as well as direct assistance with completing your facility inventories. The WYDEQ is also planning training webinars to assist operators. If you have questions or would like to learn more, please contact Lori Bocchino.
