Corrective Action Plan (2025-01)
Kennecott Section 21 – UTAH18003

The purpose of this Corrective Action Plan (“CAP”) is to establish terms and conditions of
compliance for Kennecott Section 21 (“System”), system number UTAH18003, to take actions
and correct significant deficiencies identified in Exhibit A.

The Corrective Action Plan terms and conditions are described in detail in Exhibit A. As long as
the System complies with every one of the requirements in Exhibit A, the Division will:
• Temporarily allow the extended deadlines for correcting the identified significant
deficiencies,
• Temporarily hold off assessing additional points for failure to fix violations, and
• Temporarily silence the significant deficiencies and hold off reporting those to US EPA.

Nothing in this Corrective Action Plan prohibits the Division from taking further enforcement
actions if the System fails to comply with any of the requirements in Exhibit A or if an imminent
public risk exists in the System.

We, the undersigned parties, agree to the terms, conditions and deadlines set forth in the
Corrective Action Plan (see Exhibit A).
