2. INDUSTRIAL USER INFORMATION
A. SIGNIFICANT NON-COMPLIANCE / PENALTIES
• There were two SIUs in SNC during 2022.
• Champion Powder Coating (Permit #1072) was SNC for chronic and TRC
violations for zinc and oil & grease from the January -June 2022 period.
The user discharges less than 100 gpd and the quantity of zinc from this
industry does not cause a loading concern for the Long Creek WWTP.
Champion Powder Coating had previously been SNC for zinc in the July -
December 2021 period and had been assessed a $1,000 civil penalty which
was held in abeyance pending compliance for the following period.
Because of the January -June 2022 SNC, payment was due on the $1,000
civil penalty that had been held in abeyance, a new $2,000 civil penalty was
issued and held in abeyance, and a Consent Order was issued. In February
2022, the user ceased discharge to the POTW to comply with permit
requirements. On 8/18/2022, user provided sufficient documentation to
waive the $2,000 civil penalty assessment for the SNC in 2022.
• Owens Corning (Permit #1068) was SNC for the January -June 2022 period
for a spill into the wastewater system which was not promptly reported to
TRU as required. TRU determined that this spill caused, alone or in
combination with other discharges, interference or pass through (BOD
violations) at the Long Creek WWTP. Owens Corning was assessed a
$10,000 civil penalty for the SNC and effects of the spill on 6/2/2022.
• A $1,000 civil penalty was also collected in 2022 from Industrial Fabricators
(Permit #1062) due to industry being SNC for July -December 2021.
B. ORDERS AND SCHEDULE INFORMATION (See attachment)
• Champion Powder Coating, an CIU, is currently on a Consent Order
effective 8/8/2022. The Consent Order includes the options to either cease
Page 3 of 6

discharge and request rescinding the permit, or resume discharge that
meets SIU permit requirements due to installation of a new pretreatment
system or confirmed source removal. Currently, the user continues
transporting all process wastewater to offsite 3rd party treatment and has
not taken any action to resume discharge.
C. AUTHORIZATIONS TO CONSTRUCT (AtoC)
• None
D. MISSING IDSF DATA
• Champion Powder Coating (SIU Permit # 1072) stopped process discharge
in February 2022. Sampling requirements for 2022 were not conducted
since flow was ceased before sampling was able to occur.
• Darling Ingredients (SIU Permit # 1047) did not discharge and therefore no
sample was collected for the July -December 2022 period.
• MANN+HUMMEL (SIU Permit # 1067) did not obtain 24-hour flow for the
4th quarter due to a broken effluent wastewater meter that was waiting on
parts for repair.
E. OTHER IDSF DATA COMMENTS
• All TTO and OCPSF Pollutants
TTO Certifications are input as "Certified" except when TTO sampling
was performed.
• Flow Limit compliance judgment
Daily flow limits are all evaluated on 24-hr flow reading during TRU
sampling events. Monthly flow limits are evaluated from monthly meter
readings.

B. INDUSTRIAL WASTE SURVEY
The five-year IWS Report was received by DEQ on June 26, 2020. Pretreatment
staff receives monthly notifications of building permits issued and
planning/zoning changes that relate to industrial areas. In 2022, new industrial
customers were evaluated using the following criteria: City of Gastonia billing
database, North Carolina Manufacturers Register, economic development
reports and status updates, phone calls, site visits, IWS form or wastewater
permit applications. The next full five-year IWS Report is due June 30, 2025.
The following IUs were further evaluated during 2022:

C. OTHER MUNICIPALITIES
Town of Cramerton and City of Belmont
The Town of Cramerton transferred the sewer system, including the Eagle Road WWTP,
to TRU in 2011 by an inter -jurisdictional agreement (IJA). A portion of the City of
Belmont's wastewater is treated at the Eagle Road WWTP. An IJA is in place with the
City of Belmont. No SIUs are located in Town of Cramerton or the portion of Belmont
that discharges to the Eagle Road WWTP, therefore a pretreatment program is not
required for the Eagle Road WWTP.
Towns of McAdenville, Ranlo and High Shoals; City of Lowell
A portion of the wastewater from Lowell and all the wastewater from the other
municipalities is treated at the Long Creek WWTP. TRU has IJAs with these
municipalities. These municipalities do not have any SIUs at this time and therefore do
not require a pretreatment program. The Town of Ranlo has an inactive pretreatment
program.
Town of Stanley
All wastewater from the Town of Stanley's collection system is treated at the Long
Creek WWTP. TRU has an IJA with the Town of Stanley. TRU also has a contract
agreement for operations of the town's pretreatment program. A separate PAR is
submitted by TRU for the Town of Stanley (Program # WQCS00180). Two SIUs
discharge to the town's collection system.
Town of Clover, City of Bessemer City and City of Kings Mountain
Wastewater from Clover, Bessemer City and Kings Mountain is treated at the Crowders
Creek WWTP. The Cities of Bessemer City and Kings Mountain operate pretreatment
programs regulated by NC DEQ. The Town of Clover operates a pretreatment program
regulated by South Carolina DHEC. IJAs are in place with each municipality and SIU
permits have been issued to each by TRU.

Headworks Analysis Spreadsheet The NPDES Loading (lbs/day) for Total Nitrogen [cell E411 reflects the mass based NPDES limit. The concentration based formula was
POTW Name: CrOWderS overwritten. Since the summer seasonal limit is more restrictive, that limit was used and was divided by the days in the summer monitorin€
period to calculate a daily limit.
Date: 10/30/2019 64,251 lbs/summer = 300.25 lbs/day
POTW NPDES # => NC0074268 zlval rat summer
Based on the same removal rate, the NPDES Loading was then calculated by the normal formula.
POTW Sludge Permit # => W00001793 An NPDES Loading for TKN and Organic Nitrogen [cells E43 and E44] was calculated from the NPDES Loading for Total Nitrogen based offthr
ratio of these constituents measured in the influent.
POTW NPDES Permitted Flow(MGD)= 6 -used in AT only Since the influent averaged 31.25 mg/LTKN, 31.51 mg/L TN and 13.9 mg/L ON:
NPDES Loading for TKN = NPDES Loading for TN * 31.25/31.51= 1804lbs/day
POTW Average Flow(M GD)= 2.963 -Used in HWA calculations NPDES Loading for ON= NPDES Loading for TN*13.9/31.51=802lbs/day
Uncontrollable Flow(M GD)= 1.2981 The NPDES Loading for Total Phosphorous [cell E421 reflects the annual mass based NPDES limit caclulated for daily in a similar manner.

Consent
Order

County of Gaston
In the matter of the City of Gastonia
Pretreatment Permit No. 1072
held by Champion Powder Coating, Inc.
CONSENT ORDER
Pursuant to the Sewer Use and Industrial Wastewater Pretreatment Ordinance, Section 14-396(b), the POTW director
is empowered to enter into consent orders, assurances of voluntary compliance, or other similar documents
establishing an agreement with the person responsible for the noncompliance. Such orders will include specific action
to be taken by the discharger to correct the noncompliance within a time period also specified by the order.
Pursuant to provisions of the Sewer Use and Industrial Wastewater Pretreatment Ordinance of the City of Gastonia,
this Consent Order is made effective the '1k day of 5 , 2022 between Champion Powder Coating,
Inc. (hereinafter the "User"), and the City of Gastonia (hereina er the "City").
The User and City hereby stipulate and agree as follows:
User is authorized to discharge wastewater into Two Rivers Utilities (TRU) sanitary sewer system in
accordance with limitations and other conditions set forth in the Wastewater Discharge Permit # 1072
(hereinafter the "Permit," which shall refer to User's existing permit and any subsequent renewals or
modifications thereof).
User was significant noncompliance (SNC) for zinc violations during the July -December 2021 period and
again during the January -June 2022 period.
3. User elected to install storage tanks in February 2022 to have all process related wastewater hauled offsite
for disposal by a third party vendor.
4. User hereby agrees to the following:
a) Meet and comply with all terms and conditions of the Permit (except as modified by this Order); and all
applicable local, state, and federal laws, rules and regulations applicable to the discharges from User's
facility to the City's POTW.
b) Continue to haul -off process wastewater by a third party vendor at the user's sole expense until user
submits a written request to, and receives written approval from, the City to resume process wastewater
discharge that meets requirements of SIU permit #1072 due to either installation of a new pretreatment
system or confirmed source removal of zinc.
1of2

c) User may forgo installation of a new pretreatment system or confirmed source removal of zinc, and
request to rescind SILT permit #1072. However, the City may issue a non -significant discharge permit
and require documentation of hauling events.
d) If by 6/30/2023 no action is taken concerning future discharge to the City, the City will revoke SILT
permit #1072. A non -significant discharge permit will be issued that prohibits discharge of process
wastewater and requires maintaining documentation of its disposal.
Any violations of the terms of this Consent Order or the terms of the Permit shall subject the User to the
enforcement authority outlined in the Sewer Use and Industrial Wastewater Pretreatment Ordinance of
the City as it now exists or as it may hereafter be amended. Such action may include, but is not limited
to, severance of the sewer connection and/or penalties up to $25,000 per day per violation, as may be set
forth in the Code of Ordinances of the City, as amended from time to time.
The POTW Director may alleviate enforcement of this item, per their discretion, due to mitigating
factors. User may direct any appeals to the Director of Public Utilities.
