ATTACHMENTS: Applicable Supporting Documentation Included Jordan Garahana <jordangarahana@utah.gov> Aggregate Fee due 1 message Jordan Garahana <jordangarahana@utah.gov>Thu, Oct 31, 2024 at 12:22 PM To: cbrp2@yahoo.com Hey Wess, This is Jordan Garahana from the state of Utah Division of Air Quality. I am emailing you to remind you about the aggregate fee that you are required to pay annually. It has been brought to my attention that you have an outstanding payment due for previous years of not paying the fee. You have been sent reminders previously from the state about this outstanding balance and since you haven't paid, the bill has been referred to the Utah Office of State Debt Collection. You will need to contact collections in order to see a revised total of what you owe since they add fees for late payments. I have attached a copy of the fees that were originally owed to this email for your reference. You can visit this website, to see what ways you can repay your debt, or you can call and pay over the phone at 801-957-7700. Please let me know if you have any questions. Thanks, Jordan Garahana -- Jordan Garahana Environmental Scientist | Minor Source Compliance M: (385) 271-2871 airquality.utah.gov Emails to and from this email address may be considered public records and thus subject to Utah GRAMA requirements.
