Re: Renewal Application of NPDES Permits
Crowders Creek Wastewater Treatment Plant (NPDES #NC0074268)
Dear Sir or Madam:
Please find attached, the renewal application for the City of Gastonia's National Pollutant Discharge Elimination
System (NPDES) Permit #NC0074268 for the Crowders Creek Wastewater Treatment Plant. This permit renewal
application with attachments is being submitted by the March 4, 2020 deadline to comply with the requirement to
apply 180 days prior to the date of permit expiration (August 31, 2020). As requested, please find the original signed
version of this information along with two copies. A copy of this cover letter is included inside each packet.
The Crowders Creek Wastewater Treatment Plant continues to operate as a secondary treatment biological nutrient
removal plant treating municipal wastewater for the City of Gastonia and surrounding area. Since the last permit
renewal request, numerous maintenance items and minor upgrades have taken place throughout the facility.
Authorizations to construct have been obtained where appropriate. Examples of these upgrades are shown below
and more information can be provided if desired:
• Installed an online total suspended solids meter in the aeration basin
• Installed new dissolved oxygen monitoring system in the aeration basin
• Rehabilitated and repainted anaerobic digester lid and repaired gas piping
• Installed soft starts on two main lift pumps
• Rebuilt barscreen
• Rebuilt main lift pump #1
• Rebuilt grit pump and auger
• Rebuilt digester mixer
• Replaced DAF drive unit
• Rebuilt or replaced numerous motors
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. This application includes all
data gathered for the last four and one-half years (July 1, 2015 through December 31, 2019).

Crowders Creek WWTP continues to meet the requirements for reduction in monitoring frequencies in NPDES
Permits for exceptionally performing facilities for BOD, TSS, NH3-N and Fecal Coliform as outlined in DWs 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 per week for Crowders Creek WWTP. A copy of the data
used for this evaluation is included as additional information in the renewal packet.
With this permit renewal, the following change is being requested:
The instream monitoring of Crowders Creek has shown no noticeable impact from the treatment plant
discharge, however it requires significant resources to conduct.
o The standard deviation in DO between the upstream and downstream samples is 0.1 mg/L, the
standard deviation in conductivity between upstream and downstream is 45 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 per week in the summer. To
ensure staff safety, TRU requires two staff members be present to perform sampling from these
bridges. Staff drive 18 miles/day (1638 miles/year) and spend 62 minutes/day (94 hours/year) to
collect the instream monitoring samples required by Crowders Creek WWTP's permit. The cost to
TRU in staff time and equipment is $75.94/event ($6,911/year).
o For 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.
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 regarding 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 plant. Crowders Creek WWTP's
Page 2 of 3

influent was sampled nineteen times since TRU's mercury minimization plan was made effective
in September 2017. The influent sampling showed a maximum result of 0.12 µg/L and an
average result of 0.03842 µg/L. Crowders Creeks WWTP's effluent was also sampled nineteen
times since September 2017 and showed a maximum result of 0.00142 µg/L and an average
result of 0.00044 µg/L.
Two Rivers Utilities remains committed to good environmental stewardship and its obligation to protect the
receiving stream. If I can provide any additional information or assistance regarding this application or these
requests, please contact me at 704-842-5106 or [e-mail].

SUPPLEMENTAL APPLICATION INFORMATION
PART E. TOXICITY TESTING DATA
POTWs meeting one or more of the following criteria must provide the results of whole effluent toxicity tests for acute or chronic toxicity for each of the
facility's discharge points: 1) POTWs with a design flow rate greater than or equal to 1.0 mgd; 2) POTWs with a pretreatment program (or those that are
required to have one under 40 CFR Part 403); or 3) POTWs required by the permitting authority to submit data for these parameters.
• At a minimum, these results must include quarterly testing for a 12-month period within the past 1 year using multiple species (minimum of two
species), or the results from four tests performed at least annually in the four and one-half years prior to the application, provided the results
show no appreciable toxicity, and testing for acute and/or chronic toxicity, depending on the range of receiving water dilution. Do not include
information on combined sewer overflows in this section. All information reported must be based on data collected through analysis conducted
using 40 CFR Part 136 methods. In addition, this data must comply with QA/QC requirements of 40 CFR Part 136 and other appropriate QA/QC
requirements for standard methods for analytes not addressed by 40 CFR Part 136.
• In addition, submit the results of any other whole effluent toxicity tests from the past four and one-half years. If a whole effluent toxicity test
conducted during the past four and one-half years revealed toxicity, provide any information on the cause of the toxicity or any results of a
toxicity reduction evaluation, if one was conducted.
• If you have already submitted any of the information requested in Part E, you need not submit it again. Rather, provide the information
requested in question EA for previously submitted information. If EPA methods were not used, report the reasons for using alternate methods.
If test summaries are available that contain all of the information requested below, they may be submitted in place of Part E.

Process Flow Description
The Crowders Creek WWTP is a 6-MGD facility operated by the City of Gastonia which discharges
to Crowders Creek. Influent wastewater enters the plant through a 42" gravity feed sewer line
and passes through coarse manual and one inch mechanical screens then to a grit collector. Grit
is pumped to a screw auger for dewatering prior to disposal. Following preliminary treatment,
the wastewater flow enters the main lift station. Four influent pumps lift the influent flow to a
splitter box where the flow is split to two primary clarifiers. Raw sludge from the bottom of the
primary clarifiers is drawn off and pumped to the anaerobic digesters. The primary clarifier
effluent is combined with the return activated sludge (RAS) in a second splitter box where the
flow is split to two biological treatment trains. The biological treatment follows a modified
Ludzak-Ettinger process and consists of anaerobic, anoxic and oxic basins, with optional step
feed and internal oxic recycle pumping for denitrification. Following the biological treatment
process, flow is combined in a third splitter box and routed to the two final clarifiers. Sludge
from these clarifiers is routed to the second splitter box as RAS or thickened in a dissolved air
floatation thickener (DAFT) and sent to the anaerobic digesters as waste activated sludge (WAS).
The effluent flow from these final clarifiers is again combined then split to two polishing ponds.
Effluent from these polishing ponds 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 a three -stage static aeration device to
a 48" line, which discharges through an effluent channel and into Crowders Creek. The plant has
a belt filter press and solids contact reactor that are currently not being utilized. The process
flow schematics show all of the processes of the treatment plant along with backup power
sources. The plant has three generators with outputs of 500 KW, 750 KW and 1000 KW located
throughout the plant.

The SIU uses plastic/nylon which is then injection molded into textile travelers. Nylon travelers are dyed on site, and waste from the
dying process is sent to the user's pretreatment system. Steel wire is first drawn to diameter according to customer needs. The user also
cleans/pickles steel wire using HCL or H2SO4 and performs copper coating using copper sulfate. The acid pickling (HCI) is a 628
gallon tank which is dumped 1 /year. Rinse water discharges to pretreatment system when in operation. The alkaline cleaner is a 628
gallon tank which is dumped 1/year. Rinse water discharges to pretreatment system on production days that acid pickling is done.
There are 6 small wire drawing and copper coating machines that have 75 gallon copper sulfate tanks which are mixed with sulfuric
acid and dumped 3 times a year. Rinse water is discharged every working shift. After treatment, process effluent travels to Two Rivers
Utilities (TRU) Crowders Creek WWTP.

Crowders Creek Wastewater Treatment Plant
NPDES Permit # NCO074268
The Crowders Creek Wastewater Treatment Plant (WWTP) design for sludge handling consists of
anaerobic sludge digestion followed by land application. This plan describes the processes in place
for treating and disposing of this material.
Anaerobic Digestion:
The anaerobic digestion system consists of four tanks, each with a volume of approximately
466,000 gallons, which treat the primary and waste -activated sludge from the WWTP. On average,
Two Rivers Utilities sends approximately 29,000 gallons of raw and thickened wasted solids to
these digesters each day for treatment. Two of these digesters are covered and capable of being
heated, so both may be used as primary digesters. Currently one of the digesters is being heated
and operated as a primary digester, one digester is used as a secondary digester, and two digesters
are utilized as holding digesters for biosolids storage.
Raw sludge from the bottom of two primary clarifiers is pumped to the primary digester where it is
retained for at least 15 days at a temperature greater than 35°C. Wasting from the secondary
clarifiers is also pumped to the primary digester, however these solids are first thickened in the
dissolved air floatation thickener (DAFT) unit. The digested sludge is transferred from the primary
digester into the unheated secondary digester, before being transferred and stored in the holding
digesters until transported for land application.
Crowders WWTP final holding digesters each have a capacity of 466,000 gallons. Additionally, Two
Rivers Utilities operates a residuals storage facility at its Resource Recovery Farm located between
Dallas and Cherryville. This facility is capable of storing an additional eight million gallons of
biosolids when application activities are hindered by inclement weather.
The Crowders 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.
