RE: Replacement in Kind Notification (AO DAQE-AN109170049-24; Title V Operating Permit No.
5700001004)
Mr. Bird,
Pursuant to Utah Administrative Code R307-401-11, Compass Minerals Ogden Inc. is notifying
the Division of Air Quality of the planned replacement of the BA501 Salt Line 1 Bagger of the Salt plant.
BA501 is over 30 years old and is no longer supported by the OEM. Successful completion of this
project will eliminate the current safety and ergonomic risks, and the need for back engineered and
fabricated replacement components associated with the existing bagger system. This project will not result
in debottlenecking of upstream or downstream air emission units above currently permitted throughput
limits.
These changes will be completed during an upcoming plant outage scheduled for May 5, 2025,
through May 19, 2025.
These changes meet the criteria for Replacement in Kind under UAC R307-401-11(2) as outlined
below:
a) the potential to emit of the new bagger operation will be the same as the existing bagger;
b) the number of emission points or emitting units will remain the same;
c) no additional types of air pollutants will be emitted as a result of the replacement;
d) the new bagger will be identical to equipment currently installed at the Salt Plan.
e) replacement of the bagger will not change the basic design parameters of the replaced equipment;
f) the replacement does not trigger a New Source Performance Standard or National Emissions
Standards for Hazardous Air Pollutants under 42 U.S.C. 7411 or 7412; and
g) the replacement does not violate any other provision of Title R307.
Please contact Ian Wright ([e-mail], [phone]) if you have any
questions regarding the information provided.
In accordance with Operating Permit provision I.K and UAC R307-415-5.d, and based on
information and belief formed after reasonable inquiry, I certify that the statements and information in this
document are true, accurate, and complete.

Respectfully,

Brandon Risner
Vice President - Operations
Compass Minerals Ogden Inc.
