Dear Ms. Dunman:

Re: Kinder Morgan Altamont LLC – Altamont South Gas Processing Plant – Gas Compression
Engines CE-2, CE-3, and CE-4 - Protocol Review and Test Date Confirmation – Duchesne
County

The testing protocol dated June 6, 2025, for the Kinder Morgan Altamont LLC – Altamont South
Gas Processing Plant – Gas Compression Engines CE-2, CE-3, and CE-4 located at the Altamont
South Facility in Duchesne County, Utah, has been reviewed and found to be acceptable. The
agreed upon test date is the week of July 14, 2025.

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.
