Ownership Change Forms

Did you know that Ownership Change Forms should be filled out when facility acquisitions occur and/or company name changes take place? The Air Quality Division has attached the Change of Ownership Forms for Minor Sources and Title V Facilities below for your convenience. These forms need to be completed and mailed to the following address:

ATTN: Planning Section

Wyoming DEQ - Air Quality Division
200 W 17th St, Ste 300
Third Floor
Cheyenne, WY 82002

It is important to submit completed ownership changes in a timely manner as IMPACT portal users will not have access to newly-acquired facilities until the completed forms are received and processed.

If you have any questions about ownership changes, please feel free to email deq-air-impact@wyo.gov or contact a staff member by phone at 307-777-7391.

Below are forms associated with ownership change.

Rule Development Process
Rule Development Process

Rule development involves a process that allows for input from the public and other stakeholders. After a Proposed Rule is developed internally by DEQ/AQD, it must undergo review by both the Wyoming Air Quality Advisory Board and the Environmental Quality Council – the public is given an opportunity to comment on the Proposed Rule prior to each stage – before it can become a State Rule. The Proposed Rule is also reviewed by the Attorney General, Legislative Services Office, and the Governor’s Office before it reaches the Secretary of State’s Office and becomes a State Rule.
