Dear Mr. Jorgenson:

Re: Wapiti Operating, LLC –Sage Brush Flats – Gas Processing Plant Compressor Engine
Units #1, #2, and #3 – Protocol Review and Test Date Confirmation – Carbon County

The testing protocol for the Wapiti Operating, LLC – Sage Brush Flats Gas Processing Plant –
Compressor Engine Units #1, #2, and #3 dated February 12, 2024, has been reviewed and found
acceptable. The agreed upon test date is the week of March 18, 2024.

Acceptance of a protocol does not relieve the owner/operator and the testing contractor from strict
adherence to all applicable EPA methods, Utah Division of Air Quality (DAQ) policies, Utah Air
Quality Rules (UAQR), and methods approved by the Director. Any deviation from EPA
methods, DAQ policies, UAQR, and methods approved by the Director must be addressed
separately and express written consent given prior to commencement of testing.

The DAQ requires that all test reports include a statement signed by a responsible official
certifying that:

A. Testing was conducted while the source was operating at the rate and/or conditions
specified in the applicable approval order, operating permit, or federal regulation.

B. During testing, the source combusted fuels, used raw materials, and maintained process
conditions representative of normal operations, and operated under such other relevant
conditions specified by the Director.

C. Based on information and belief formed after reasonable inquiry, the statements and
information contained in the report are true, accurate, and complete.
