Corrective Action/M itigation
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 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.
