Re: Renewal Application of NPDES Permits
Long Creek Wastewater Treatment Plant (NPDES#NC0020184)
Eagle Road Wastewater Treatment Plant (NPDES#NC0006033)
Dear Sir or Madam:
Please find attached, the renewal applications for Two Rivers Utilities' National Pollutant Discharge
Elimination System (NPDES) Permits #NC0020184 and #NC0006033 for the Long Creek and Eagle Road
Wastewater Treatment Plants. These permit renewal applications with attachments are being submitted
by the August 4,2019 deadline to comply with the requirement to apply 180 days prior to the date of
permit expiration (January 31, 2020). As requested, please find for each plant, the original signed version
of this information along with two copies. Copies of this cover letter are included inside each packet. A
flash drive is also included with electronic copies of each application.
The Long Creek Wastewater Treatment Plant continues to operate as an advanced biological nutrient
removal plant treating municipal wastewater for the City of Gastonia and surrounding area. The Eagle Road
Wastewater Plant continues to operate as a secondary treatment plant with chemical phosphorus removal
treating wastewater for the Town of Cramerton and surrounding area. Since the last permit renewal
request, numerous maintenance items and minor upgrades have taken place throughout these facilities.
Authorizations to construct have been obtained where appropriate. Examples of these upgrades are
shown below and more information can be provided if desired:
• Replaced one of the main lift pumps at Long Creek WWTP.
• Installed new drain line for biosolids lagoon supernate and press water at Long Creek WWTP.
• Upgraded internal reuse water system at Long Creek WWTP.
• Installed two online nitrogen probes in the denitrification basin at Long Creek WWTP.
• Renovated and streamlined chlorine and sulfur dioxide feed systems at Long Creek WWTP.
• Replaced aeration basin curtain at Eagle Road WWTP.

All analyses have been tested by North Carolina certified laboratories in accordance with 40 CFR Part 136
requirements. Efforts have been made to obtain seasonal variation in the sampling as much as was
possible. This application includes all data gathered for the last three years (July 1, 2016 through June 30,
2019).
With this permit renewal, TRU respectfully requests the following changes to these permits:
Long Creek WWTP (NPDES#NC0020184)
• The Long Creek WWTP is currently permitted for summer BOD5 limits of 5.0 mg/L monthly and
7.5 mg/L weekly. TRU requests that the wintertime BOD5 limit of 10.0 mg/L monthly and 15.0
mg/L weekly be in effect year-round. The detection level for BOD5 is only 2.5 mg/L and the BOD5
test is highly subject to interferences and contaminants that are especially significant at
measurements close to the detection level. Variability caused by minor factors in the collection
and testing process can affect the results far more than the 2.5 mg/L difference between the
current summer monthly permit limit and the minimum method detection limit. Differences
such as traces of soap residue in sample containers, cologne worn by a lab technician, or tiny
pieces of algae in the sample are sufficient to cause a sample to exceed the 5.0 mg/L BOD5 limit.
Therefore even though the Long Creek WWTP performs extremely well with BOD removal and is
always well above its 94% design removal rate, this limit that is barely above the detection level
can be challenging to consistently meet. Additionally, the minor difference between the current
and requested BOD5 limit for the plant's discharge would not appear to have any significant
impact to the South Fork Catawba River.
• Long Creek WWTP continues to meet the requirements for reduction in monitoring frequencies
in NPDES Permits for exceptionally performing facilities for TSS, NH3-N and fecal coliform as
outlined in DEQ's October 22, 2012 policy statement. Therefore, in accordance with this policy
TRU is requesting that the minimum required monitoring frequency for these parameters be kept
at 2x a week for Long Creek WWTP. A copy of the data used for this evaluation is attached as
additional information in the renewal packet for Long Creek WWTP.
• The instream monitoring for Long Creek WWTP has not shown a noticeable impact from the
treatment plant discharge but requires significant resources for our utility to conduct.
o For Long Creek WWTP: the standard deviation in DO between the upstream and
downstream samples is only 0.4 mg/L, the standard deviation in conductivity between
upstream and downstream is 18 µmhos, and the standard deviation for temperature is
0.3°C. These differences are extremely minor and do not appear to show any statistically
significant effect in the stream due to the plant's discharge.
o Collecting these samples is burdensome to perform while maintaining staffing
requirements at the treatment plants—particularly when required three times a week in
the summer. To ensure staff safety, TRU requires two staff members be present to
perform sampling from these bridges and river banks. Staff drive 21 miles/day (1910
miles/year) and spend 71 minutes/day (108 hours/year) to collect the instream
monitoring samples in Long Creek WWTP's permit. The cost to TRU of this sampling in
staff time and equipment is $83/event ($7,930/year).
Page 2 of 5

o Because of these reasons, TRU requests that the instream monitoring requirements in
this permit be reduced to once-per-week on a year-round basis.
Eagle Road WWTP (NPDES#NC0006033)
• As has previously been discussed and acknowledged by DEQ Two Rivers Utilities has entered
into an agreement with Lowell Investments Ito purchase the right to the nutrient allocation
granted to NPDES Permit NC0005274 in accordance with the 1995 Lake Wylie TMDL. TRU
requests that this allocation for 144 lbs/day of TN and 7.6 lbs/day of TP, be converted to
lbs/season and added to the supplemental allocation in NPDES permit NC0006033 for Eagle Road
WWTP. A copy of the previously submitted agreement and request letter is attached as
additional information in the renewal packet for Eagle Road WWTP.
• Pharr Yarns, LLC discharged directly to the South Fork Catawba River under permit NC0004812,
but has recently been connected to Two Rivers Utilities' collection system and will rescind its
NPDES permit. At the time this application is being submitted, the final decommissioning is
expected within the next few months. TRU requests that NPDES permit NC0004812's allocation
for 50 lbs/day of TN and 8.3 lbs/day of TP, be converted to lbs/season and added to the
supplemental allocation in NPDES permit NC0006033 for Eagle Road WWTP. The ability to
transfer this allocation has also been previously discussed with and acknowledged by DEQ during
meetings in Raleigh on 8/12/10, 8/22/13, 8/28/14 and 5/24/16. Our understanding is that this
allocation will not exist without being tied to a permit, so we strongly request that any necessary
actions be taken to preserve it within permit NC0006033 as permit NC0004812 is rescinded.
• Eagle Road continues to meet the requirements for reduction in monitoring frequencies in
NPDES permits for exceptionally performing facilities for BOD5, TSS, NH3-N and fecal coliform as
outlined in DEQ's October 22, 2012 policy statement. Therefore, in accordance with this policy
TRU is requesting that the minimum required monitoring frequency for these parameters be kept
at 2x a week for Eagle Road WWTPs. A copy of the data used for this evaluation is attached as
additional information in the renewal packet for Eagle Road.
• The instream monitoring for Eagle Road WWTP has also not shown a noticeable impact from the
treatment plant discharge, but requires significant resources for our utility to conduct.
o For Eagle Road WWTP: the standard deviation in DO between the upstream and
downstream samples is less than 0.2 mg/L, and the standard deviation for temperature is
only 0.2°C. These differences are extremely minor and do not appear to show any
statistically significant effect in the stream due to the plant's discharge.
o Collecting these samples is burdensome to perform while maintaining staffing
requirements at the treatment plants—particularly when required three times a week in
the summer. To ensure staff safety, TRU requires two staff members be present to
perform sampling from these bridges and river banks. Staff drive 26 miles/day (2300
miles/year) and spend 48 minutes/day (73 hours/year) to collect the instream monitoring
samples in Eagle Road WWTP's permit. The cost to TRU of this sampling in staff time and
equipment is $66/event ($5,970/year).
o Because of these reasons, TRU requests that the instream monitoring requirements in
this permit be reduced to once-per-week on a year-round basis.

Mercury Minimization Plan:
In accordance with permit requirements, TRU implemented a Mercury Minimization plan on
September 25, 2017. Since its creation, TRU has adhered to the plan and completed the following
activities:
1. Annually surveyed at least 10% of its users in categories likely to be sources of mercury.
Thus far, TRU has requested information from all the dental offices and veterinary clinics
in its service area. Each year TRU will continue to survey users in a new category that
has potential to be a source of mercury.
2. Substances used at the wastewater treatment plants have been evaluated to determine
if they contain mercury.
o All chemicals fed as a part of the treatment process have been verified to have a
very low potential of mercury contamination.
o Mercury thermometer and laboratory reagents have been switched with non-
mercury options when available. Mercury reagents that are still necessary are
collected and properly disposed of through hazardous waste collection.
o Mercury containing fluorescent light bulbs have been or are in the process of
being replaced with non-mercury LED bulbs. All fluorescent bulbs that were
replaced have been properly disposed.
3. TRU maintains procedures and trains staff on the handling of mercury spills and the
collection of wastes. All staff are also trained on the hazards and proper handling of
mercury containing items.
4. TRU includes mercury education in its public outreach efforts including presentations to
schools and tour groups. Information is included on the City of Gastonia's website on
the health and environmental effects of mercury as well as methods for proper cleanup
and disposal.
5. Sampling for mercury has been performed at least annually on all permitted significant
industrial users as well as the influent and effluent of the treatment plants.
o Long Creek WWTP's influent was sampled seven times since TRU's mercury
minimization plan was made effective in September 2017. The influent sampling
showed a maximum result of 0.07725 µg/L and an average result of 0.04678
kg/L. Long Creeks WWTP's effluent was sampled seven times since September
2017 and showed a maximum result of 0.00179 µg/L and an average result of
0.00049 µg/L.
o Eagle Road WWTP's influent was sampled three times since September 2017 and
showed a maximum result of 0.0524 µg/L and an average result of 0.0440 kg/L.
Eagle Road WWTP's effluent was sampled twice since September 2017 and
showed a maximum result of 0.00162 µg/L and an average result of 0.00139
kg/L.
Two Rivers Utilities remains committed to environmental stewardship and takes our obligation to
protect the receiving streams very seriously. TRU requests these changes in the NPDES permits in
order to allow staff to focus on other environmental issues, such as removing the problematic
discharges from some aged treatment plants, while not overburdening our rate payers. If you would

Process Flow Description
The Long Creek WWTP is a 16-mgd facility operated by Two Rivers Utilities which
discharges to the South Fork Catawba River. Influent wastewater enters the plant
through a 48" gravity feed sewer line and passes through mechanical screens and a grit
collector. Following preliminary treatment, the flow enters the main lift station. Five
influent pumps (three duty, two standby) lift the influent flow to Manhole #1 (MH-1) and
the flow is split to three primary clarifiers. The primary clarifier effluent is combined with
the RAS in MH-2 where the flow is split to two biological treatment trains. The biological
treatment trains consist of anaerobic, anoxic and oxic basins, with internal oxic recycle
pumping (one duty, one standby per train) for denitrification. One biological treatment
train has a treatment capacity of 7-mgd and the other has a treatment capacity of 9-mgd.
Following the biological treatment trains, flow is combined in MH-6 and routed to the
denitrification basin which consists of anoxic zones for further denitrification and oxic
zones for reaeration. Flow can be diverted around the denitrification basins. The
intermediate pumping station consists of three screw pumps (two duty, one standby)
which lift the flow to four final clarifiers. From the final clarifiers, the flow is sent to gravity
anthracite filters. Eight filter cells are in place to allow cells to be taken out of service
without impacting the performance of the system. Flow can be diverted around the
filters. Filter effluent is disinfected in an open chlorine contact chamber by injection of
chlorine solution. Sulfur dioxide is injected into the chlorinated effluent for
dechlorination. Finally, the effluent is discharged through two three-stage static aeration
devices to a 54" line, which discharges to the South Fork Catawba River. The process
flow schematic shows all of the processes of the treatment plant along with bypasses
and backup power sources. The plant has three 1,600 kW generators located at the
plant entrance.

Sludge Management Plan for
Long Creek Wastewater Treatment Plant
NPDES Permit# NC0020184
The Long Creek Wastewater Treatment Plant (WWTP) design for sludge handling consists of anaerobic
sludge digestion followed by land application of class B liquid biosolids. This plan describes the
processes in place for treating and disposing of this material.
Anaerobic Digestion:
The anaerobic digestion system consists of four heated anaerobic sludge digesters and two sludge
holding digesters, each with a volume of approximately 450,000 gallons. The anaerobic digesters treat
the primary and waste-activated sludge generated from the WWTP. On average, Two Rivers Utilities
sends approximately 50,000 gallons of raw and thickened wasted solids to these digesters each day for
treatment.
Raw sludge from the bottom of three primary clarifiers is pumped to the primary digesters where it is
held at a temperature greater than 35°C. Wasting from the secondary clarifiers is also pumped to the
primary digesters, however these solids are first thickened in the dissolved air floatation thickener unit
located adjacent to the digesters. Following digestion in the primary digesters, solids transfer to the
holding digesters and then are pumped into the sludge storage lagoons.
The WWTP has two biosolids storage lagoons, with a combined capacity of four million gallons.
Additionally Two Rivers Utilities operates a residuals storage facility at its Resource Recovery Farm
located near Bessemer City. This facility is capable of storing an additional eight million gallons of
biosolids when application activities are hindered by inclement weather.
The Long Creek WWTP currently complies with the 503 pathogen reduction requirement for Class B
biosolids by a PSRP process (40 CFR Part 257 Appendix II). Pathogen reduction is demonstrated by fecal
coliform testing. Vector attraction reduction is demonstrated by a measurement of 38%volatile solids
reduction using the Van Kleeck's equation.
Land Application Program:
For beneficial reuse of these biosolids,Two Rivers Utilities utilizes land application for disposal of these
solids. Gastonia contracts with EMA Resources to perform this land application. Biosolids are land
applied to 2,085 acres of local farmland in North Carolina, in accordance with NC DEQ Land Application
Permit WQ0001793 and 283.5 acres in South Carolina under SC DHEC Land Application of Domestic
Sludge Permit ND0084883. 173.65 of the acres in North Carolina are TRU owned land at the Resource
Recovery Farm and the remainder is private farmland.
