1119795 07/29/2023 DMON Ammonia was reported only 1x/week for the week ending 7/29, and total coliform was reported only 2x/week for the week ending 7/29. The lab does not typically need to void samples so this is not likely to occur again. Violation B eSMR
1119155 06/30/2023 DMON Discharger did not report characterization monitoring at EFF-001 and RSW-001 during Q2 2023 as required in the NOA, due to a laboratory error. Violation B Report
1118322 05/18/2023 DMON Discharger did not report BOD at EFF-001 at the required frequency (NOA requires 1/week, and discharger reported BOD 0/week). City staff and lab personnel will ensure samples are processed within hold time Violation B eSMR
1115798 04/05/2023 Order Conditions 4/5/2023 CEI found that effluent flow meter had not been calibrated since 8/25/2020, and MRP section I.D requires calibration at least yearly. Violation B Inspection

1103769 03/31/2022 DMON Discharger did not monitor DOC at RSW-001 and RSW-002 during Q1 2022 as required in the MRP. The new permit that began February 2022 requires dissolved organic carbon to be sampled at RSW-001 and RSW-002, the permit ending January 2022 does not. Our contracted lab will initiate this testing in Q2, the first full quarter under the new discharge permit. Violation B eSMR
1103770 03/31/2022 DMON Discharger sampled NO2/NO3 only once in March instead of twice as required in the MRP. Discharger recorded the number of UV banks in use only once during 2-31 March , instead of continuously as required in the MRP. Staff has been directed to sample twice monthly in the future. Violation B eSMR
1100009 12/31/2021 DMON The SPL-001 sample was received by our contract laboratory, but only the EC result was reported. In the future we will verify the contract laboratory reports both EC and TDS results. Violation B eSMR
