Harold / Joe –
I have mailed copies of our annual certification to the UDAQ director and EPA Region 8 for 2023, and have attached
copies to this email.

The first report references Permit #300030004 and covers the period of 1/1/23 to 11/8/23.
The second report covers the new Title V permit that was issued on 11/09/2023 and references permit #300030005

If you have any questions or need further information, please let me know.
