RE:Report of Potential Permit Deviation (Operating Permit No. 5700001004)
Mr. Bird,
ln accordance with Operating Permit provision 1.S.2.c, and Utah Administrative Code (UAC) R307-
a15-5a(3Xc)(ii), Compass Minerals Ogden lnc. (Compass Minerals) is reporting potential deviations from
permit condition ll.B.2.a. associated with salt harvest.
Condition: The following production limits shall not be exceeded; 1,685,0N) tons of solt horvested
from ponds per rolling 72-month period.
Monitoring: The permittee shall colculote o new 72-month totol by the 2dh doy of each month
using doto fram the previous 72 months.
On November 28, 2023, Compass Minerals determined that the l2-month rolling sum of
harvested salt had exceeded the indicated production limit for the months of September and October
2023, as noted in the table below. The facility's environmental compliance management system is
configured to track and document permit required tasks through to completion; in this case, however, the
manual task of calculating a new l2-month rolling total by the 20th of each month for the previous 12
months was missed on two consecutive months, allowingthe potentialexceedance of the production limit
to go undetected.
After this issue was identified, Compass Minerals completed a detailed review of the manner in
which the Company tracks and records harvested salt and determined that, in addition to the months of
September and October of 2023, the preceding and subsequent months of August 2023 and November
2023 also potentially exceeded the 12-month rolling production limit for harvested salt:

Upon discovery of the deviation, salt harvest was halted and will not be restarted until the rolling
average is within permit limits. To improve tracking of salt harvest tonnage and to prevent a reoccurrence

rpt.
of this exceedance, Compass Minerals intends to add the metric to an existing business analytics solution
to provide better visibility to harvesting production limits throughout the month and to a wider audience.
Further, Compass Minerals has reviewed the importance of timely completing these reports and
immediately identifoing salt harvest tonnages that are approaching the harvest limit and addressing the
issue with the Operations team.
Finally, Compass Minerals reviewed the basis for the salt harvest tonnage limit, which was
required as a means of minimizing fugitive dust emissions and does not implicate downstream process
limits in any other part of the plant. As previously discussed with Division of AirQuality, the salt harvested
off the ponds is wet with a high percentage of magnesium chloride, which substantially limits the creation
of dust during harvesting activities. lndeed, at no point in the last four months has Compass Minerals
identified any exceedance of opacity limits in the area of the salt harvest.
Please contact Vikrant Chavan ([e-mail], [phone]) if you have any
questions regarding the information provided.
ln accordance with Operating Permit provision l.K and UAC R307-415-5.d and based on
information and belief formed after reasonable inquiry, I certifo that the statements and information in
this document are true, accurate, and complete.
