Dear Mr. Weinert:

Re: Wesco Operating, Inc. – Cane Springs 25-19-34-1, Cane Creek 24-2, Cane Creek 36-2 –
Protocol Review and Test Date Confirmation – Grand County, Utah

The testing protocol for three (3) natural gas engines at Cane Springs 25-19-34-1, Cane Creek
24-2, and Cane Creek 36-2 dated May 16, 2024, has been reviewed and found acceptable. The
agreed upon test date is the week of June 17, 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 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.
