Dear Ms. Combs:

Re: Kinder Morgan Altamont, LLC – Bluebell Gas Processing Plant – Compression Engines
C-161, C-162, C-163, C-252, C-253, and C-258 – Protocol Review and Test Date
Confirmation – Duchesne County

The testing protocol dated February 4, 2025, for emissions testing of the Kinder Morgan
Altamont, LLC – Bluebell Gas Processing Plant – Gas Compression Engines C-161, C-162,
C-163, C-252, C-253, and C-258, located near Altamont, Duchesne County, UT, has been
reviewed and found to be acceptable. The agreed upon test date is the week of March 10, 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.
