The City continues to use the team approach for implementation of the Industrial Pretreatment Program (IPP). The Industrial Waste Control Manager is Gerald Tyrone Battle who has oversight of the planning and implementation of the program. Two full time Coordinators are dedicated to the Industrial Waste Control (IWC) Division. They conduct sampling and provide equipment maintenance among other tasks to ensure that all requirements of the program are met. Sample analyses are provided by the City of Durham's state -certified Laboratory Services Program. Both the IWC and the Lab Services Programs are housed at the Compliance Services Building located at the South Durham campus. Both programs are under the management of Mrs. Mary Tiger, Assistant Director, City of Durham, Department of Water Management. Ms. Vicki Westbrook retired September 1, 2022. Mrs. Tiger joined us January 30, 2023. These changes have been requested for the Pretreatment Program Info Databases. The City of Durham's Industrial Pretreatment Program currently has 12 Significant Industrial Users (SIUs). The North Durham Water Reclamation Facility (NDWRF) basin has 8 SIUs, including 5 Categorical Industrial Users (CIUs), and the South Durham Water Reclamation Facility (SDWRF) basin has 4 SIUs which includes 1 CIU. During this reporting period: orth Durham AWNC (Permit #1011) was granted a Consent Order (February 2020) for Zinc with the goal of returning to compliance in the short and long term. Due to the continued impact of COVID, AWNC requested two extensions during 2021. Both were granted. AWNC returned to compliance. The Consent Order expired February 2022. AWNC changed their name to AISIN North Carolina Corporation. A permit modification was issued stating as such. Freudenberg (#1021) received a permit renewal that included a decrease in flow. City of Durham 2022 PAR Page 1 Merck (Permit #1038) received a permit modification that included the addition of a new process, an increase in flow and a name change from Merck Sharp & Dohme Corp. to Merck Sharp & Dohme LLC. Stanley Environmental Solutions (Permit #1042) received an Authorization to Construct for a new flow meter. The approximate cost was $4,000.00. VIOLATIONS: In 2022, five industries (bioMerieux, Corning, Evergreen, Novo Nordisk, Stanley Environmental Solutions) were issued Notices of Noncompliance or Violation (NNC and NOV). The violations are detailed as follows: bioMerieux The permit condition reads, "...bioMerieux will provide their daily effluent flow readings (including the monthly average) from the meter measuring Pipe 01 to this office by the 10th working day of the month for the previous month." The July report was due August 12th but was not submitted until August 16th. Corning ➢ The September 7 and 8, 2022 TN results were 271.1 and 272.9 pounds, respectively. These results exceed the daily maximum TN limit of 250 pounds per day. All remaining samples for the semi-annual period were compliant. Evergreen The permit condition reads, "...Evergreen will provide their monthly effluent flow average from the meter servicing the entire facility (Pipe 01) to this office by the 10tn working day of the month for the previous month." The February report was due March 14tn but was not submitted until April 5cn Novo Nordisk The March 8, 2022 Acetone result was 27.9 mg/L. This result exceeds the daily maximum Acetone limit of 8.2 mg/L. All remaining samples were compliant. Stanley Environmental Solutions The December 16, 2021 TSS result was 509.2 pounds. (Although the violation City of Durham 2022 PAR Page 2 occurred in 2021, the NOV was not mailed until 2022.) This result exceeds the daily maximum TSS limit of 500 pounds per day. All remaining samples were compliant. Stanley is required to sample twice per month for certain parameters. Per a June 3, 2022 email, the second sampling event was not performed. Stanley collected the missed sampling event and conducted one additional sampling event. SIGNIFICANT NONCOMPLIANCE (SNC): There were no instances of significant non-compliance (SNC) during this reporting period (January 1, 2022 to December 31, 2022).
