Dear Ms. Hahn:

Re: Morton Salt Inc. – North and South Mill Production Area Wet Scrubbers, Pellet Mill Wet
Scrubber, and Sulzer Vibrating Fluidized Bed Salt Dryer Wet Scrubber – Protocol Review
and Test Date Confirmation – Tooele County

The testing protocol for Morton Salt Inc. dated April 22, 2025, has been reviewed and found
acceptable. The agreed upon test dates for the North and South Mill Production Area Wet
Scrubbers, Pellet Mill Wet Scrubber, and Sulzer Vibrating Fluidized Bed Salt Dryer Wet Scrubber
are June 3-6, 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 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.
