City of Durham
2017 Pretreatment Annual Report
Narrative
GENERAL INFORMATION:
This Pretreatment Annual Report for the City of Durham covers the period from January
1, 2017 to December 31, 2017.
Durham continues to use the team approach for implementation of the City's Industrial
Pretreatment Program (IPP). The Industrial Waste Control Administrator is Gerald
Tyrone Battle who has oversight of the planning and implementation of the program.
Two full time technicians are dedicated to the Industrial Waste Control (IWC) Division.
They provide sampling and equipment maintenance among other tasks to insure 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 located at the South Durham Water Reclamation Facility. The
programs are under the management of Ms. Vicki Westbrook, Assistant Director, City of
Durham, Department of Water Management.
The City of Durham's pretreatment program currently has 13 Significant Industrial Users
(SIUs). The North Durham Water Reclamation Facility (NDWRF) basin has 9 SIUs,
including 4 Categorical Industrial Users (CIUs), and the South Durham Water
Reclamation Facility (SDWRF) basin has 4 SIUs which includes 1 CIU.
During this reporting period:
➢ AWNC (Permit #1011) was in Significant Noncompliance (SNC) for the
monthly average of Zinc for the second semi-annual period of 2015. Per
statute, the SNC was published in the Durham Herald Sun. The scenario was
detailed in the 2015 PAR. AWNC and the City of Durham entered into a
Consent Order April 2016. Provisions of the Order include a timetable and
course of action, monthly updates, interim limits with violation penalties and
the expectation of the installation of the proper pretreatment unit to address
each of AWNC's wastestreams. The expiration date of the Order was
extended until June 30, 2017. The Consent Order is attached immediately
following this Narrative (Attachment 1). Civil penalties were collected and
are reflected in the Pretreatment Performance Summary (PPS). There have
been no violations since the installation of the new unit. An Authorization to
Construct (A to C) was issued and the cost of the unit and installation was in
excess of $1,250,000.00.
➢ Coca Cola (Permit #1012) submitted certification letters stating they have no
process waste discharge. Therefore, no Industry Data Summary Form (IDSF)
is present. They are scheduled for a permit renewal in 2018 but have
petitioned to be dropped as an SIU. They plan to maintain their status as a
City of Durham 2017 PAR Page 1

distribution warehouse and have no intention of returning to the bottling
process. Their request will be assessed in the near fixture.
➢ Freudenberg Performance Materials (Permit #1021) was issued a permit
renewal that included the addition of an acceptable pH range.
➢ Angelica Textile Services (Permit #2015) received a permit modification to
reflect a change in ownership as well as changing the name to Angelica.
There were also changes to the language pertaining to flow. Angelica
received an Authorization to Construct for the installation of an effluent flow
meter. The cost associated was $30,377.00.
VIOLATIONS:
In 2017, three industries were issued Notices of Noncompliance or Violation (NNC and
NOV). They are AWNC, bioMerieux and Angelica. The violations are detailed as
follows:
AWNC
➢ The monthly average limit for BOD is 3,000 mg/L. The Technical Review
Criteria (TRC) limit is 4,200 mg/L. The November 2016 monthly average was
3,077 mg/L. It exceeded the monthly limit of 3,000 mg/L; not the TRC
criteria.
➢ The BOD daily maximum and monthly average limits are 4,000 and 3,000
mg/L respectively. The Technical Review Criteria (TRC) limits are 5,600
and 4,200 mg/L. The February 21, 2017 result was 4,250 mg/L. This result
violates the chronic daily maximum limit. The February monthly average was
3,925 mg/L. It violates the chronic monthly limit.
➢ The BOD daily maximum and monthly average limits are 4,000 and 3,000
mg/L respectively. The Technical Review Criteria (TRC) limits are 5,600
and 4,200 mg/L. The April 12 and 13, 2017 results were 6,850 and 4,650
mg/L respectively. The former result violates the chronic and TRC limits.
The latter violates the chronic daily maximum limit. The April monthly
average is 5,750 mg/L. It violates the chronic and TRC monthly limits.
➢ Per the Consent Order signed April 2016, the daily maximum and monthly
average limits for Total Oil and Grease are 900 and 700 pounds respectively.
The TRC limits are 1260 and 980 pounds respectively. During November
2016, the results in pounds were:
November 1 — 489.3
November 4 — 587.4
November 8 — 961.8
November 9—1,038.2
City of Durham 2017 PAR Page 2

Monthly Average — 769.2
As indicated by the bold, November 8 and 9 are daily violations and the
monthly average was violated as well. These are chronic violations; at this
time, there are no TRC violations.
➢ Per the Consent Order signed April 2016, the daily maximum and monthly
average limits for Total Oil and Grease are 900 and 700 pounds respectively.
The TRC limits are 1260 and 980 pounds respectively. During February
2017, the monthly average in pounds was 745.8. This result was a chronic
violation of the Consent Order monthly average for Total Oil and Grease.
➢ Per the Consent Order signed April 2016, the daily maximum and monthly
average limits for Total Oil and Grease are 900 and 700 pounds respectively.
The TRC limits are 1260 and 980 pounds respectively. During April 2017,
the results in pounds were:
April 12—1,056.0
April 12 — 889.7
April 13 — 779.1
April 13 — 829.1
Monthly Average — 888.5
As indicated in bold, one of the April 12 samples was a daily violation and the
monthly average was violated as well. These are chronic violations.
➢ Per the Consent Order signed April 2016, "Upon start up and refinement of
the pilot pretreatment program(s), AWNC will collect compliance samples for
Zinc and Oil and Grease once per week and submit the results from a NC
Division of Water Resources certified laboratory to the City for compliance
judgment for the duration of the pilot program.... Sampling will not be
required in the periods prior to and during installation and fine tuning of the
pilot and permanent pretreatment system(s)." The system was running
consistently for the last five weeks of the Consent Order which expired June
30, 2017. Please note the following chart:

These results violate the daily maximum limit. Additional compliant data has
been submitted.
Angelica
➢ The daily maximum for flow is 150,000 gallons (150 MGD). The flow
