RE: Deviation Report For Permit No. 4300001003
Date: 1112912022
In accordance with Operating Permit Provision I.S.2.b, Utah Administrative Code (UAC)
R3 07-4 I 5-6a(3)(c)(ii) the following report is submitted:
1. List the date the deviation occurrred: 1112512022
Permit conditions for which deviation occurred: II.B.3.b
Describe the deviation that occurred: At 9:58am emissions greater than 10
percent opacity were emitted from the Number 3 stack. This condition existed for
approximately 6 minutes.
Describe the probable cause of the deviation: A sudden loss of pressure in the
compressed air system caused a bypass of the baghouse.
Describe any corrective actions or preventive measures taken: The kiln was shut
down until air pressure could be restored. The cause was determined to be moisture
freezing in an air line. Because of the frozen line, air pressure had to be routed to the bag
house from a different air line. Once air pressure was restored the kiln was restarted.
In accordance with Operating Permit provision I.K and UAC R307-415-5d, and based on
information and belief formed after reasonable inquiry, I certify that the statements and
information in this document are trueraccurate, and complete.
