Discharae Monitoring Reports (eDMRs) were reviewed for the period September 2017 through August 2018. Daily maximum effluent BOD and TSS violations were reported in February 2018. Only one effluent ammonia sample (twice per month required) was collected and reported in January 2018 and August 2018. The Division has previously addressed these limit and monitoring violations through the issuances of either a NOV or civil penalty assessment. The 10-day interval between the collection of the twice per month effluent ammonia samples was not adhered to in March 2018. The ORC and staff will amend the August 2018 eDMR to accurately reflect the facility visitations (five days per week instead of three).

The ORC and staff must ensure to perform post -analysis calibration checks on the pH meter following field analyses at multiple sites. Post -analysis calibration checks must be performed in accordance with the NC Wastewater/Groundwater laboratory certification approved procedures for the analyses of PH. Note: Post analysis checks would also be required for dissolved oxygen and total residual chlorine meters if applicable. Effluent Sampling Is composite sampling flow proportional?
