City of Durham
2022 Pretreatment Annual Report
Narrative
GENERAL INFORMATION:
This Pretreatment Annual Report for the City of Durham covers the period from January
1, 2022, to December 31, 2022.
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:
North 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.
i= 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 101n working day of the month for the previous month." The
February report was due March 141n but was not submitted until April 51n
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.
