Mooresville Regional Office staff has reviewed your Pretreatment Annual Report (PAR) for the reporting period
of January through December 2018. Based on the review, this.letter is being issued as a Notice of Violation (NOV)
due to the City's failure to properly implement the Pretreatment Program. Specifically, the City failed to determine
Significant Non -Compliance (SNC) status for Hickory Springs (lUP #101HS) during both six month periods in 2018.
One of the three nickel results reported in each of the six month periods was a Technical Review Criteria'violation
and therefore, the SIU was in SNC during both six month periods. Please be advised that the City must determine
SNC status according to 40 CFR 403.8(f)(2)(viii), 15A NCAC 2H .0903(b)(34), and local sewer use ordinance.
The City's Pretreatment Coordinator must ensure that the 2019 PAR includes the SNC designations (Narrative,
SNC form, PPS form, etc.) and a copy of the Public Notice. The remaining elements of the 2018 PAR was evaluated
and found to be in accordance with 15A NCAC 2H .0908(b) requirements and guidelines set forth in the
Comprehensive Guidance for North Carolina Pretreatment Programs. A copy of the Public Notice must be submitted
to this Office by May 10, 2019. The next PAR will be due March 1, 2020.
It is requested that a written response be submitted to this Office by May 17, 2019, addressing -the City's actions to
prevent the recurrence of these violations. In responding, please address your comments to Mr. Bell.

FILE REVIEW COMMENTS:
17. The POTW reported a weekly average effluent ammonia violation and monthly average BOP and ammonia violations in June 2015. The
POTW continues rehabilitation efforts on the collection system to reduce I&I flows.
35. POTW performed SIU inspections on 5119115 (ECI) and 7/23/15 (Hickory Springs).
39. The POTW contracts Water Tech Labs to perform analyses. The POTW only collected one cyanide sample (semi-annual monitoring
requirement) for Hickory Springs in 2015
41a. ECI contracts Pace Analytical Services, Inc. to perform analyses. Hickory Springs contracts Blue Ridge Labs to perform analyses.
44. Hickory Springs samples zinc on a monthly basis.
46. Hickory Springs was issued a NOV on 9/10/15 for zinc violations (daily maximum and monthly average) during the POTW sampling event
in July 2015.
SUMMARY AND COMMENTS:
Comments: The POTW issued a letter dated 3/24/14 to ECI allowing the submittal of the daily flow and pH monitoring data/reports with the
quarterly metals results; however, ECI's 11UP was not officially modified. The IUP's required detection levels for zinc, cyanide, and oil &
grease were not being met by ECI's contracted laboratory. In addition, the POTW's contracted laboratory was not meeting the required
detection levels in ECI's IUP for zinc and oil & grease.
The chain of custody form for Hickory Springs' contracted laboratory indicated the incorrect sample type for cyanide (composite) and metals
(grab). Hickory Springs' 1UP requires grab cyanide samples and composite metals sampling.
The chain of custody form for the POTW's contracted laboratory revealed that the only cyanide sample collected by the POTW for Hickory
Springs in 2015 was unpreserved.
Requirements: The POTW must modify any IUP when monitoring frequencies, limits, and/or detection levels are changed. In addition, the
IUP's permit history must also be updated to document these changes. The POTW indicated. that the ECI IOP will be modified and updated
(permit history page) to reflect the changes to the monitoring frequencies (pH and flow) and laboratory detection levels (cyanide, zinc, and oil &
grease). A modified ECI IUP (draft) must be submitted to the PERCS Unit for review/approval by July 1 2016.
The POTW must review all chain of custody forms to ensure all samples are being properly collected and preserved. The POTW will contact
Hickory Springs to verify the sampling procedures and determine if the chain of custody forms were being properly transcribed.
The POTW shall collect two additional cyanide samples for Hickory Springs in 2016 to make up for the missed cyanide sample and the
unpreserved cyanide sample in 2015. The POTW must ensure all samples are properly preserved as required by 40 CFR 136.3, Table II.

FILE REVIEW COMMENTS:
1. Both SIUs are under the control of the City of Conover; however, their discharges go to the City of Newton. The City of Newton
determines the appropriate limits based on the Newton HWA, available allocation, and NPDES and land application concerns. Conover
provides copies of all pretreatment related materials to Newton.

21. The POTW's ERP was last approved on 4/13/94; however, this document (including Division approval letter) was not available for
review during the inspection. The ERP has not been updated to reflect the updates listed in the Division's 2008 Model.
72. POTW inspection dates: Hickory Springs, 5/1/14; Engineered Controls, 4/3/14.
76. The POTW failed to perform annual TSS and oil & grease monitoring as required by Hickory Springs IUP in 2014.
78. Hickory Springs contracts Blue Ridge Environmental and Engineered Control contracts Pace Analytical Services to perform
analyses.
81/85. POTW issued -a NOV to Hickory Springs for daily maximum and monthly average zinc violations (August 2014).
82/85. POTW issued NOVs to Hickory Springs and Engineered Control for late submittals of the TTO certifications.
83b. Hickory Springs performs monthly monitoring per IUP.

Industrial Inspection Comments:
The facility's pretreatment system includes an accumulation tank, initial pH tank, cation/anion resin vessels, final pH tank, flow
measurement, and discharge. No sludge is produced and FCC Environmental is contracted to remove machine. coolants.
SUMMARY AND COMMENTS:
Audit Comments: The POTW did not adhere to the Division's protocols when the IUP for Engineered Controls was modified on
7/29/13 and 3/24/14. The POTW reduced the monitoring requirements from monthly to quarterly on both dates.
The; Pretreatment Coordinator must ensure all records are organized and accessible. .
Requirements: The IUP for Engineered Controls should be modified to show updated IUP history, new effective date, new effluent
limits/monitoring page, and new signed cover page. The IUP should be submitted to the PERC's Unit for review and approval within
thirty (30) days of receipt of inspection report.
An updated ERP based on the Division's 2008 Model should be submitted to the PERC's Unitwithin thirty (30) days of receipt of
inspection report.
Recommendations:
The Hickory Springs IUP should be properly modified (same requirements as noted above for Engineered Controls) if the POTW
intends to remove the TSS and oil & grease monitoring requirements. The POTW should also review and update any 1UPs that have
pH limits as averages.

FILE REVIEW COMMENTS:
Question 34: The IUP Application was signed on 7/13/07
Question 35: The SIU was inspected on 7/12/11.
Questions 36 and 37: The Slug and Spill Control Plan and the TOMP were prepared in 2005. The Slug and Spill Control Plan
and the TOMP must be updated or certified that no changes have occurred at the SIU relative to the Plans.
46: A Notice of Noncompliance was issued to Engineered Controls for a zinc violation on 7/5/11.
SUMMARY AND COMMENTS:
Comments:
The SIU discharges to the City of Newton, Clark Creek WWTP. The City of Conover and City of Newton have entered in an
Interjurisdicational Agreement (IJA) to address compliance and enforcement of the Engineered Controls. The IUP is written based on the
City of Newton headworks and Federal'Categorical Standards. No SIUs discharge to the City of Conover WWTP. The Newton Clark
Creek experienced one weekly average TSS effluent limit violation in October 2010 (Case No. LV-2011-0011). The IJA requires that all
documentation regarding the SIU be shared between the POTWs.
Requirements:
See the Pretreatment Program Elements Review Section of this report.
The Slug and Spill Control Plan and the TOMP must be updated or a certification statement submitted by the SIU stating that all
information in the Slug and Spill Control Plan and the TOMP is still correct.

PCI SUMMARY AND COMMENTS:
PCI Comments: Engineered Controls was included on the previous PCI as being in SNC for limits - the two inspections overlap for
the time frame of the previous two six-month periods.
LTMP monitoring has been reduced at the Conover NE WWTP because there is no longer a SIU discharging to the facility.
Requirements: Because the only remaining SIU discharges to the Citv of Newton. a revised IIWA for the Conover NE NN7VTP is
no longer required.
