Dear Mr. Pollock:

Re: Chevron Products Company – Alkyl Furnace F3601, Coker Furnace F-70001, Crude
Furnaces F-21001 and F21002, and FCC – Salt Lake Refinery – Protocol Review and Test
Date Confirmation – Salt Lake County

The testing protocol for the Chevron Products Company’s Alkyl Furnace F3601, Coker Furnace
F-70001, Crude Furnaces F-21001 and F21002, and FCC, received June 3, 2024, has been
reviewed and found to be acceptable. The agreed upon test date is August 26-30, 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.
