Dear Ms. Bridwell:

Re: Compliance Advisory Response - Uinta Wax Operating LLC, Tryon 10-19-2-1E, Uintah
County

The Utah Division of Air Quality (DAQ) received a response letter from Uinta Wax Operating
LLC (UWO) dated December 8, 2023, regarding a Compliance Advisory
(DAQC-CA155110001-23) for potential violations of the Utah Air Quality Rules. This
information provides some clarification and is addressed in the paragraphs below. Please respond
within 15 days of receipt of this letter.

In Comment/Item #1: UWO requested clarification on the citation which referenced R307-501-2.
The correct reference should be R307-501-4. The observation was specifically questioning the
proper configuration of the controls as referenced in the Requirement and Rule section of the
letter.

For Items #2 and #3, no further action is required at this time.

For clarification, the DAQ issues Compliance Advisories when additional information or actions
are necessary to complete our inspection reports, and these are not considered formal notices of
violations. As stated in our Compliance Advisory letters, the document could lead to a No Further
Action, Warning, or an offer for an Early Settlement Agreement to quickly close out the
Compliance Advisory based upon the company’s response. As a last resort, the Compliance
Advisory could be elevated to a formal Notice of Violation which could then be handled with the
involvement of legal counsel on both sides. The Compliance Advisory process is intended to
focus on the field-level expectations and understanding at the sites. For this purpose, the field
personnel can participate and know exactly what we look for and expect at each site. The DAQ
intends to keep the action of this Compliance Advisory as simple and efficient as possible to
quickly address the issues that negatively affect the air quality in the Uinta Basin. Good air
quality is an essential element affecting the quality of life of your employees, local citizens, as
well as meeting the requirements for continued good business opportunities in the Uinta Basin.
