Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) RECORD KEEPING SECTION cont'd: On several occasions from October 2019 through February 2020, effluent values (lead, turbidity, TSS, copper, iron and ammonia) were not reported down to the analytical method's detection/reporting limit (a "0" was reported). Please be advised that the subject permit requires that all data generated must be reported down to the minimum detection or lower reporting level of the test procedure [Permit Condition Reference: Part II Section D (4) Test Procedures]. The minimum ten (10) day interval between the collection of the twice per month effluent TDS samples was not adhered to in December 2019. In addition, the September 2019 eDMR should be revised to include the ORC/Backup ORC visitation on 9/30/19. All eDMRs must be reviewed to ensure all units of measurement (UoM) are consistent with the UoMs listed in the permit (ex. all metals and salinity effluent results).

Discharae Monitoring Reports (eDMRs) were reviewed for the period July 2019 through June 2020. Nc effluent limit violations were reported all monitoring frequencies were correct. Effluent chronic toxicity failures were reported in September 2019, December 2019, March 2020 and June 2020; however, chronic toxicity is a monitoring only requirement. The chain of custody forms should be updated to show sample type and preservative (if applicable) for each parameter sampled and the time when samples were placed on ice. See "Summary" Section for additional comments.
