The following actions have been taken to correct our mistake: 1. We contacted Amanda Hatcher (NC State Extension Office) to complete and updated our calibration records. Please see enclosed copies of the calibrations completed on 5- 13-21. 2. Reminders and updates are discussed in our meetings as well as continual checks to ensure the schedules are accomplished by the due dates according to our Swine Management Waste Permit. This violation was an oversight, and we are certain that it will not happen again with the new measures we have put in place. Please contact us if there are further questions or concerns.
