Subject: Notice of Deficiency
Pretreatment Audit Inspection
City of Newton
NPDES Permit No. NC0036196
Tracking #: NOD-2021-PC-0414
Catawba County
Enclosed is a copy of the Pretreatment Audit Inspection (PAI) Report for the inspection of the City of Newton's
Industrial Pretreatment Program on July 27, 2021, by Mr. Wes Bell of this Office.
This report is being issued as a Notice of Deficiency (NOD) due to the City's failures to initiate enforcement
according to the Division -approved Enforcement Response Plan (ERP), violations of North Carolina General Statute (G.S.)
143-215.1, 15A North Carolina Administrative Code (NCAC) 2H .0905 and subject NPDES Permit. Specifically, the City
failed to initiate enforcement on Special Metals (Permit #: 1015) for nickel limit violations that occurred during the March
through June 2021 monitoring period. In accordance with G.S. 143-215.6A, a civil penalty assessment of not more than
twenty-five thousand dollars ($25,000.00), or twenty-five thousand dollars ($25,000.00) per day when the violation is of a
continuing nature, may be assessed against any person who violates or fails to act in accordance with the terms, conditions,
or requirements of any permit issued pursuant to G.S. 143-215.1.
It is requested that a written response be submitted to this Office by August 27, 2021, addressing the City's actions
to prevent the recurrence of these violations. The response should include the City's enforcement action to address the
nickel permit limit violations. In responding, please address your comments to the attention of Mr. Bell. Should you have
any questions concerning this report, please do not hesitate to contact Mr. Bell at (704) 235-2192, or via email at

® Yes ❑ No If yes, Explain.
33. Has any one from the public ever requested to review pretreatment program files? El Yes ® No
If yes, Explain procedure. If no, How would the request be addressed? An official procedure has not been developed; however,

procedure for determining whether information qualified for confidential status, as well as procedure for keeping files confidential
from public. If no. how would the request be addressed? An official procedure has not been developed; however, the Public

Permitting (Industrial Waste Survey-IWS):
38a. How does the POTW become aware of new or changed Users? The IWS — Short Form is given to new users by the
City's Economic Development staff and/or Planning Department. The WWTP staff and Pretreatment Coordinator
evaluate IWS information.
38b. Once the POTW becomes aware of new or changed Users, how does the POTW determine which industries have the
reasonable potential to adversely impact the WWTP and therefore require a new permit or a permit revision? (Who is an
SIU?) Categorical processes, flow, and potential loading.
39. Does the POTW receive waste from any groundwater remediation projects (petroleum, CERCLA) or landfill leachate?

Explain Other:
43. Review POTW's copies of current allocation tables for each WWTP. Are there any over allocations? ® Yes ❑ No
If yes, What parameters are over allocated? Mercury; however, since the effluent meets the stream standard and
there is no allocation to industries, no action is required per PERCS letter dated 1/16/18.
44. If yes to #44, What is being done to address the over allocations? (short-term IUPs, HWA to be revised, pollutant study, etc.)

listed on the application limited; categorical parameters; NPDES Pollutants of Concern) Categorical parameters and NPDES
POCs.
48. How does the POTW decide what the monitoring frequency should be for the various pollutants in industry permits? Explain.
Quarterly sampling for conventional parameters and metals (minimum); new SIUs performs monthly sampling for a year
to get a baseline and may be reduced to quarterly based on results/levels.
Permit Compliance:
49. Does the POTW currently have or during the past year had any permits under adjudication? ❑ Yes ® No
If yes, which industries? What was (will be) the outcome of the adjudication?
50. Demonstrate how the POTW judges compliance. This should include compliance judgment on all violations of limits, reporting
requirements, and permit conditions, as well as for SNC. Compliance Judgement Worksheet - SNC determinations; violations
(limit, monitoring, reporting, etc.) based on approved ERP.
51. Does the POTW use the Division's model inspection form or equivalent? ® Yes ❑ No
If no, does the POTW form include all DWQ data? ❑ Yes ❑ No
52. Were all SIUs evaluated for the need of a slug/spill control plan during their most recent inspections? ® Yes ❑ No
If no, Explain.
53. What criteria are used to determine if a slug/spill control plan is needed? Chemical storage practices, presence and locations of
floor drains and secondary containment, potential impacts to WWTP.
54. What criteria does the POTW use to determine if a submitted slug/spill control plan is adequate? Emergency contacts kept
current, proper storage practices and secondary containment, adequate spill response equipment.
55. How does the POTW decide where the sample point for an SIU should be located? POTW samples both categorical waste
streams and all combined waste streams.
56. Has the POTW established a procedure to ensure that representative samples will be taken by the POTW or SIU each time?
POTW: ® Yes ❑ No SIU: ® Yes ❑ No If yes, Explain. POTW — Laboratory and sampling manuals/SOPs;

FILE REVIEW COMMENTS:
16. Special Metals was in SNC during second half of 2020 for nickel limit violations.
71. SIU inspections were performed by the POTW on 2/26/20 (Technibilt) and 9/2/20 (Special Metals).
77. Technibilt and Special Metals both contract Pace Analytical Services to perform IUP analyses.
NC DWR Pretreatment Audit Form Revised: July 25, 2007
Page 5
84. The POTW issued NOVs to Technibilt for BOD and TSS permit limit violations in January 2021 (BOD) and April 2021 (TSS).
The POTW issued NOVs to Special Metals for chromium and nickel permit limit violations (Pipe 002) in January and February 2021.
A $2,000.00 civil penalty was issued for the 1/12/21 and 1/14/21 chromium and nickel violations. In addition, a $400.00 civil penalty
was issued for late payment.
The POTW placed Special Metals under a Consent Order in March 2021 due to the SIU being in SNC (for nickel permit limit
violations) for two consecutive semi -annul periods in 2020. The POTW failed to enforce on the nickel violations reported from March
2021 through June 2021 according to the Division -approved ERP.

Industrial Inspection Comments:
The facility manufactures welding products such as tig wire, mig wire, coated electrode, etc. The facility has 65 employees and
operates four to five days per week with only the annealing line operating 24-hrs. per day. The alkaline spent bath and rinse bath waste
streams flow through a five -micron sock filter prior to flow measurement and sampling. Any sludge (alkaline and rinse tanks, etc.) from
the cook off tanks is disposed by A&D Environmental to a permitted landfill approximately once every five weeks. The sludge in the
flux pit tank is disposed by US Waste to a permitted landfill on an annual basis. The facility is equipped with an automated notification
system (via email) to supervisory staff of any unplanned changes in production. The POTW samples both the categorical and non -
categorical waste streams.
The facility is in the planning process of installing an electrostatic filtration system to lower the nickel levels per Consent Order.
SUMMARY AND COMMENTS:
The POTW must ensure all IUP required detection levels (nickel, cyanide) are met (POTW and SIU contracted labs). Proof of penalty
collections should also be maintained with the Pretreatment staff for review during future inspections.
The POTW must enforce all nickel limit violations from March through June 2021 according to the Division -approved ERP by August
13, 2021. The failures to enforce the limit violations were attributed to confusion on the enforcement of limit violations while the SIU
was under a Consent Order which was discussed during this audit. In addition, the POTW was not aware that categorical limits could
be temporarily increased in Consent Orders.
The records reviewed during the inspection were organized and well maintained.
