10/4/2021 Ms. Glaza called about the required response to my recent Title V Air Inspection Report. I indicated that the response needed to identify the specific road dust suppression activities which will be utilized moving forward. We also discussed the non-compliance with the NESHAP LLL opacity observation frequency, and I reminded her that I advised Lehigh's Wendy Krause that I need a satisfactory response by October 8, 2021, or an NOV would be issued.
