Dear Mr. Jorgenson,

Re: Additional Information Request – Wapiti Operating, LLC – Sage Brush Flats Compressor
Station, Carbon County

On April 24, 2024, a representative of the Utah Division of Air Quality (DAQ) performed a
review of the stack test emissions results report, dated April 1, 2024, regarding stack emissions
testing of the Sage Brush Flats Compressor Station engines CE-01, CE-02, and CE-03 performed
on March 19, 2024. In order to ensure that the results of that review are accurate and complete,
DAQ requests the following additional information:

1. The total logged hours of operation that occurred between the July 27, 2022, testing and
March 19, 2024, testing of engine CE-03. The July 27, 2022, testing report recorded the
total hours to be 76,666 prior to testing and the March 19, 2024, testing recorded the total
hours to be 90,965. This calculates out to be 14,299 hours between testing of engine
CE-03. 40CFR 60, Subpart JJJJ stipulates a maximum of 8,760 hours of operation between
stack emissions tests.

2. Any supporting documents and reasoning as to the cause and circumstance of the total
hours of operation exceeding the required 8,760 hours maximum between tests.

Wapiti Operating, LLC is required to submit this additional information to DAQ within ten (10)
business days of receipt of this request. When responding to this information request, please refer
to the DAQC number located on the top right corner of this document.

Failure to respond to this additional information request may result in enforcement action. Utah
Code Section 19-2-115 provides that violators of the Utah Air Conservation Act and/or any order
issued thereunder may be subject to a civil penalty of up to $10,000 per day for each violation.
