10/8/2021 Rachel called on the 7th with questions regarding dust suppression permit requirements. I deferred to David Miller who had performed the inspection and had requested the information. On the 8th, Rachel requested chlorine residual information for the last bacteria samples which she believed to have taken place in September. The last sample on record was 8/30/21, I provided her the data from that sample. DAVID KNOLL
