2. INDUSTRIAL USER INFORMATION
A. SIGNIFICANT NON-COMPLIANCE / PENALTIES
• There were no SIUs in SNC during 2020.
• There was 1 IU in SNC during 2020. IBC Specialties was SNC for a discharge of
volatile organics on February 4, 2020. IBC had previous NOVs and penalties for
similar discharges. An NOV with a civil penalty of $8,000 was assessed on
4/2/2020. User entered into a Consent Order on 6/9/2020 requiring construction of
pretreatment devices to prevent future occurrences. $4,000 of the Civil Penalty
was held in abeyance pending successful completion of the Consent Order (see
section B. ORDERS AND SCHEDULE INFORMATION for more details).
B. ORDERS AND SCHEDULE INFORMATION (See attachment)
• No SIUs were under orders or schedules during 2020.
• IBC Specialties, Inc., an IU, entered into a Consent Order on 6/9/2020 to meet and
comply with all terms of the permit. The Consent Order includes installing a pH
monitoring and control system as well as a method to prevent the discharge of
volatile organics into the sewer system. The system plans were submitted on
8/31/2020 and approved on 10/27/2020 after multiple rounds of updates and
comments. The amended Consent Order requires completion of the installation of
the system by 3/1/2021 with operational procedures in place by 3/15/2021.
C. MISSING DATA
• Choice (SIU Permit # 1035) Discharge to Long Creek WWTP
o User stopped production and discharge on 9/5/2019. Monthly sampling
requirements for all of 2020 have not been conducted since there has not been
any process flow. Because the treatment facilities were in place and the facility
is still owned by Choice, the permit was not rescinded until December 2020.
Self -Monitoring reports were submitted each month of 2020.
• BOD Analysis - Invalid Discharge to Long Creek WWTP
o Sampling and analysis for BOD was completed for five industry samples
collected at the end of February through the first week of March 2020. Due to
issues with the analysis, valid results were not able to be obtained from the
laboratory for these samples. This affected BOD samples from the following
SIUs: Town of Stanley Pipe 001 & 002, Wind River Environmental, Altus, and
Mann+Hummel These industries do not have a limit for BOD and the missing
data was determined not to cause any concern, therefore extra sampling events
were not performed. BOD was collected and analyzed during the next sample
event.
• Valley Protein (SIU Permit # 1047) Discharge to Crowders Creek WWTP
Page 3 of 6

o User had zero discharge in the 4th quarter of 2020. No sampling was performed
during this quarter since there was zero flow.
D. OTHER DATA COMMENTS
• TTO and OCPSF Pollutants
o TTO Certifications are signified as "Certified" unless there was a sample
collected.
o Lubrizol is a CIU regulated under 40 CFR 414.85. OCPSF data for the first six
month period is listed as "BDL" because all required OCPSF parameters had
results below detection levels. All detection levels were lower than the limits
listed in 40 CFR 414.111.
• BDL Comments
o Oil and Grease analysis for the samples of AB Carter, Gaston County Landfill,
Kings Mountain, Lubrizol, Modena and PCSI resulted in BDL results above the
permitted detection levels because the laboratory had insufficient sample
volume to achieve detection levels less than or equal to 5 mg/L. Compliance
evaluation can be determined with a higher detection level, so TRU has decided
to replace "Required Laboratory Detection Limits" with "Recommended
Laboratory Detection Limits" for Oil and Grease in future modified and
renewed permits.
o BDL results for metals and TSS that were above permitted "Required
Laboratory Detection Limits" had either interference that caused multiplication
of the dilution factor or other laboratory reasons that were justified. The City of
Gastonia Crowders Creek Laboratory and commercial laboratories used by IUs
are aware of the detection levels required for all parameters.
E. AUTHORIZATIONS TO CONSTRUCT (See attachments)
• Owens Corning (SIU Permit # 1068) Discharge to Long Creek WWTP
o An Authorization to Construct was granted for the installation of additional
treatment units. Plans are for installation of a 0.5 MG EQ tank with mixing
abilities and a pH control system to balance out the pH range during discharge.
• The A to C was granted on November 18, 2020.
• Construction began in January 2021, and is scheduled for completion at
the end of the 1st quarter of 2021.
• IBC Specialties (IU Permit # 2014) Discharge to Long Creek WWTP
o An Authorization to Construct was granted for installation of a pretreatment
system to provide flow equalization, monitor for VOCs and control pH. Plans
are for installation of a system of two tanks, volatile organics monitor, and a
system for pH monitoring and control.
• The A to C was granted on October 28, 2020.
• Construction began in January 2021, and is scheduled for completion
by 3/1/2021.

C. INDUSTRIAL WASTE SURVEY
The five-year IWS Report was submitted on June 18, 2020. Pretreatment staff
receives monthly notifications of building permits issued and planning/zoning changes
that relate to industrial areas. All industries were evaluated in 2020 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 five-year IWS Report is due
June 30, 2025. The following IUs were further evaluated:

D. OTHER MUNICIPALITIES
Town of Cramerton and City of Belmont
Wastewater from Cramerton and a portion of Belmont is treated at the Eagle Road
WWTP. TRU owns the collection system within the Town of Cramerton and there are
no SIUs. An inter jurisdictional agreement is in place with Belmont. Belmont operates
a pretreatment program, but has no permitted IUs that discharge to TRU. Discharges to
the system are monitored and a pretreatment program will be activated for Eagle Road
WWTP if needed.
Towns of McAdenville, Ranlo and High Shoals; City of Lowell
TRU has inter jurisdictional agreements 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. A portion of the wastewater
from Lowell and all the wastewater from the other municipalities is treated at the Long
Creek WWTP.
Town of Stanley
TRU has an inter jurisdictional agreement with the Town of Stanley. TRU also has a
contract agreement for operations of the town's pretreatment program. Two SIUs
discharge to the town's collection system. All wastewater from the Town of Stanley's
collection system is treated at the Long Creek WWTP. A separate PAR is being
submitted by the Town of Stanley (Program # WQCS00180).
Town of Clover, City of Bessemer City and City of Kings Mountain
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. Inter jurisdictional agreements are in place with each
municipality and SIU permits have been issued by TRU to each. Flow from each of
these municipalities is treated at the Crowders WWTP.

The NPDES Loading (Ibs/day) for Total Nitrogen [cell E41] reflects the mass based NPDES limit. The concentration based formula was
overwritten. Since the summer seasonal limit is more restrictive, that limit was used and was divided by the days in the sum mer monitoring

An NPDES Loading for TKN and Organic Nitrogen [cells E43 and E44] was calculated from the NPDES Loading for Total Nitrogen ba sed off the
ratio of these constituents measured in the influent.
Since the influent averaged 31.25 mg/L TKN, 31.51 mg/L TN and 13.9 mg/L ON:

Problem Statement + Objectives
To ensure future compliance with Wastewater Discharge Permit#2014, IBC Services, Inc. ("client") intends
to install a wastewater holding system that will meet the following requirements:
• Receives wastewater from the facility in an isolated reservoir (labeled "PIT 01" on System Sketch
in Appendix A).
• Moves wastewater via float -activated pump to a primary retention tank (labeled "TANK 01" on
System Sketch in Appendix A) for pH monitoring and correction.
• Drains treated wastewater from primary retention tank into release reservoir (labeled "PIT 02"
on System Sketch in Appendix A) for discharge into Two Rivers Utilities (TRU) sanitary sewer
system.
• Provides secondary retention tank (labeled "TANK 02" on System Sketch in Appendix A) for pH
correction and balancing of additional volume.
• Provides automatic pH monitoring and control.
• Provides activated carbon filtration to treat for volatile organic compounds.
The intent of this report is to detail the proposed system and provide justification that it meets the needs
of IBC Service, Inc. to ensure future compliance with their permit requirements.
Report Summary
This report presents the system design proposed by Riddle Consulting ("engineer") to meet client's
obligations, with system designed to ensure ease of monitoring and control of wastewater pH and volatile
organic compounds, with client's programs and procedures governing use and maintenance.
Per information received from client:
• Total system usage is between 3000-6000 gallons per day.
• Estimated pit volume is 500 liquid gallons.
• Operations philosophy will include automatic pH monitoring and control, prescribed by client's
programs and procedures.
The system is designed to incorporate existing on -site pits (Pit #1 and Pit #2 in Appendix A), using two
additional tanks and a series of ball valves to allow for tank bypass and control of inflow and release to
the sanitary sewer system. The system design includes automatic pH monitoring and dosing pumps to
allow for operator -free measuring and dosing to remain within permitted limits; manual release to the
sanitary sewer system will allow operators to verify acceptable pH has been achieve prior to release to
the sanitary sewer.
A carbon filtration system, as seen in Appendix A or allowable substitution, will be used to control for
volatile organic compounds in wastewater before release to the sanitary sewer.
Evaluations of the tanks to determine anchorage requirements, and qualification of the existing concrete
pad, were performed in accordance with ACSE 7-05 and ACI 318-11.
Engineering Report 2 i

CONSULTING PLLC

System Design
Per client's information, between 3000-6000 gallons per day of wastewater are produced from the facility.
The two (2) 3000-gallon tanks, plus Pit #1, provide enough storage space plus contingent retention to
intake and treat wastewater from the facility during a typical day of operation.
Valves isolating Tank #1 and Tank #2 can be operated in such a manner as to transfer wastewater from
Pit #1 into either Tank for treatment, and then transfer the treated water back to Pit #2 for release to the
sanitary sewer system.
The system is intended to operate by pumping wastewater from Pit #1 into the selected Tank (selected
by manual operation of isolation valves) in order to monitor pH and treat automatically as necessary.
Manual operation of the valves will release water within allowable pH range into Pit #2 for release into
the sanitary sewer system. The existing condition of Pit #1 and Pit #2 will be modified by adding a wall or
other suitable barrier between the pits to ensure no untreated wastewater from Pit #1 is released directly
to Pit #2 for release to the sewer system. Selection of tanks, interval for release, chemicals for treatment,
and other procedures related to the use of system will be at the client's discretion to ensure permit
compliance.
The control system as specified will measure and display the pH within each tank and can automatically
and continuously adjust pH to given set points within the range of 5.5 — 9.5 pH. The client will be
responsible for selecting set points for the control system, and for manual release of the wastewater to
the sanitary sewer system when it is found to be within permit limits; system set points and manual
release will be per client's procedures. For sampling and data recording, a BLE-equipped sensor (HOBO
MX2501 Data Logger, or approved substitute, as shown in Appendix A) should be used.
For system level monitoring, a float sensor will be installed on Tank # 1, Tank #2, and Pit #1. Sensors will
be set per client's procedures to activate audible and visual alarms at sensor set point; client's procedure
will dictate alarm monitoring and operations activity to ensure tanks or pit are not filled beyond capacity.
To avoid possible operations interruptions, it is recommended that the client maintain a back-up pump
that may be easily substituted for the primary pump in Pit #1, in the event a pump failure event causes
sensor set point trips.
In case of system spill or overflow, barriers specified on schematic will ensure that no unintended release
to the sanitary sewer occurs. Additionally, existing covers for Pit # 1 and Pit #2 will be modified to allow
proper system function and ensure rainwater does not enter the pits. The enclosure for equipment, as
specified in the attached plans, is waterproof and does not present a concern for weather intrusion.
Client states current operation limits introduction of volatile organic compounds (VOCs) through off -site
disposal of any material with significant VOC concentrations. Monitoring of trace VOCs will be achieved
through the client's procedures, employing a monitoring system (such as the NovaTest W1000 Online VOC
Monitor, or approved substitution) before wastewater is pumped into the holding and treatment tanks.
Client's procedures should address use of carbon filtration for trace VOCs.

Structural Design
Methodology for Analysis of Tank:
Water retention tanks specified in the bill of material in Appendix A were analyzed to:
• determine base shear and bearing qualification of existing concrete pad to support the Toad.
• Determine anchorage requirements for tanks.
Anchorage for Tanks:
Tank is considered self -anchored per Section 15.7 of ASCE 7-05. Table 15.7-1 states 4" lateral motion must
be accounted for in cases where J = 0.785 < J < 1.54. Therefore, plans presented call for adequate space
between tanks to allow for possible seismic motion, as well as flexible hose connections to ensure piping
runs are not broken during a seismic event.
Tank Bearing on Concrete:
Bearing pressure and shear per ACI 318-11, Chapter 22, is within allowable limits, considering a 4" thick
concrete slab.
Conclusion + Exceptions
Summary system justification:
System tanks have been sized to ensure wastewater from facility within a given day (consisting of two full
8-hour shifts) can be held and treated.
Automatic monitoring and dosing ensure that information on pH is accurate and readily available from a
central panel; manual release ensures that operators can verify pH readings at the panel before release
to the sanitary sewer.
Client's procedures and programs will need to be in place to ensure the proper use of the specified system
for maximum assurance of the desired system results.
Additional system components, such as tank agitators, may be specified as needed by client's chemical
engineer or other qualified individual.
Summary structural justification:
Evaluation of the tanks defined in Appendix A, in accordance with ACI 318-11, determined that the existing
concrete pad as placed is sufficient for the system identified.
Exceptions:
Electrical connections should be evaluated and installed by a qualified electrician.
Installation of piping should be completed by a qualified individual.
System chemistry and procedures controlling system chemistry are not covered in this report; client
should work with a qualified individual to ensure procedures are in place to control system chemistry.

Re: Owens Corning Large EQ Tank Instillation — Drawings
Significant Industrial User Permit #1068
Owens Corning — Gastonia Plant
Dallas, North Carolina
Dear Mr. English and Mr. Alexander:
Per our previous conversations and earlier letters, the Owens Corning site is planning to install a new 500,000gal EQ
tank with agitation and a new acid tank at our Dallas, NC facility. This addition to our waste water system is designed
to help reduced spikes in pH, create a more consist discharge flow and help mitigate TSS though dilution. Please find
attached three (3) Copies of the following documents for the Authorization to Construct.
R113406 Z Binder Waste Collection and Treatment
R113407 W Waste Water Collection Pad
R150143 B EQ Tank Equipment Arrangement
R150146 EQ Tank Piping Arrangement
R150147 EQ Tank Piping Sections and Details
R150148 EQ Tank Piping Sections and Details
M29923 Site Civil General Notes
M29924 A Grading and Utility Relocation Plan
M29925 Typical Section and Details
M29926 Structural General Notes
M29927 Structural General Notes
M29928 A Tank Foundation Plan
M29929 A Foundation Details and Sections
The new EQ tank will be located south of the existing bow screen structure and the new acid tank containment will be
located just north of the current EQ tank on inside the current containment. There will be a new platform built that will
extend off the existing bow screen structure that will allow access for observation of the top of the EQ tank.
The first step in this process will be rerouting a storm water line and pouring the foundation for both the larger EQ
tank and the new containment for the acid tank, The facility is looking to get this part of the project completed by the
end of the year.
We appreciate the working relationship between TRU and Owens Corning. If you have questions or need further
information, please contact me at 412-715-6395
