Mr. Quinten Bingham
Granite Construction Company

Salt Lake City, UT 84116

Dear Mr. Bingham:

Re: Granite Construction Company – Cottonwood Facility – Protocol Review and Test Date
Confirmation – Salt Lake County

The testing protocol for the BMG 45 R 30 Drum Mix Asphalt Plant located at the Cottonwood
Facility in Salt Lake County dated May 10, 2024, has been reviewed and found acceptable. The
agreed upon test dates are July 15-17, 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 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.
