• 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 4,2015
deadline to comply with the requirement to apply 180 days prior to the date of permit expiration
(August 31, 2015). 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 which treats 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 connection allowing for potable water to be used in place of internal reuse water.
This use facilitates flushing of water system lines in the area.
• Automated pumping of Return and Waste Activated Sludge (RAS/WAS).
. • Installed vault providing access to secondary effluent line.
• • Replaced emergency backup generator#3 with larger size (500 kwH) allowing for full
• backup power to digesters and laboratory/control building.
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 (January
. 1, 2012 through December 31, 2014).
With this permit renewal, we respectfully request the following changes to our permit:
• As discussed with Mr. Mike Templeton, Mr. Tom Belnick and Ms. Kathy Stecker, and as
outlined in a 6/23/14 letter to Mr. Templeton; we request that limits for Total Nitrogen
and Total Phosphorus for this facility be expressed as lbs/day limits. We also request
that credit be applied to this lbs/day limit for the Bessemer City Wastewater Treatment
• Plant. An allocation for total nitrogen and total phosphorus is given to the Bessemer
• City WWTP in the Lake Wylie TMDL, but the plant has been decommissioned and the
flow is being treated at the Crowders Creek WWTP. A copy of the 6/23/14 letter with
details of this request is included in the back of the permit renewal packet.
• Data for the last three years has been evaluated, and the Crowders WWTP meets the
• requirements for reduction in monitoring frequencies in NPDES Permits for
• exceptionally performing facilities as outlined in DENR's October 22, 2012 policy
statement. In accordance with this policy, we are requesting that the minimum
required monitoring frequency for BODS, TSS, NH3-N and fecal coliform be reduced to 2x
a week. A copy of the data used for this evaluation is attached in the back of this permit
renewal packet.
• • Upstream and downstream monitoring has not shown a noticeable impact from the
• treatment plant discharge, but can be burdensome to perform while maintaining
staffing requirements at the treatment plant—particularly when required three times a
week in the summer. We request that the upstream and downstream monitoring
requirements be reduced to once-per-week year-round.
• • Quarterly monitoring for Nickel, Copper, Zinc and Silver at the Crowders Creek WWTP
• effluent have shown results summarized below for the last three years. We request
• that these monitoring frequency requirements be removed.
•
Average Concentration Maximum Concentration
• Nickel 2.9 µg/L 4.1 µg/L
Copper 2.6 gg/L 8.0 µg/l_
Zinc 35.2 µg/ 53.9 µg/L
Silver <1.0 µg/L <1.0 µg/l_
• • Monthly monitoring for mercury at the Crowders Creek WWTP effluent showed an
• average mercury concentration of only 0.0004 µg/l_and a maximum concentration of
0.0025 µg/L. We request that this monitoring frequency requirement be reduced to
quarterly and the permit limit be removed.
• Quarterly monitoring for bis(2-ethlyhexyl)phthalate has shown only one detectable
• result in the last three years. This result of 14.7 µg/L was from a sample collected by
• pumping through flexible tubing using a peristaltic pump. The fourteen samples taken
• since changing to collecting the samples by dippers have all been below detectable
levels. Since bis(2-ethylhexyl)phthalate is commonly used as a plasticizer, we believe
the tubing used at the time was the source of the bis(2-ethlyhexyl)phthalate instead of
�•L
i

• actually being present in the effluent discharge. We request this monitoring frequency
• requirement be removed.
Two Rivers Utilities remains committed to good environmental stewardship and take our
obligation to protect the receiving stream very seriously. We request these changes in the
NPDES permits in order to allow us to focus on other environmental issues (such as removing
• the problematic discharges from some smaller municipalities) while not overburdening our rate
• payers. If I can provide any additional information or assistance regarding this application or
these requests, please feel free to 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.
a 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.
a 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.
• a 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.

Additional Information for NPDES Permit Application
Section B.3. Process Flow Diagram or Schematic
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 screw collector. Following preliminary treatment, the 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. 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.

Sludge Management Plan
• for
• 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 anaerobic sludge digesters, 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 24,000 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 digester are utilized as holding digesters for sludge 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 Two Rivers Utilities' 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 fecal coliform density demonstration [40 CFR 503.32(b)(2) / 15A
NCAC 02T.1106(c.)(1.)].
Vector attraction reduction is demonstrated by a measurement of 38% volatile solids reduction
• [40 CFR 503.33 (b)(1) / 15A NCAC 02T.1107(a)(1)] using the Van Kleeck's equation. At least
once per week, the % volatile solids of the raw sludge, DAFT sludge and digested sludge are
analyzed and the%VS reduction is calculated.

• FACILITY NAME AND PERMIT NUMBER: PERMIT ACTION REQUESTED: RIVER BASIN:
• Crowders Creek WWTP, NCO074268 Renewal Catawba River Basin
• 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 from Gastonia's wastewater treatment plants are land applied to permitted local
farmland in North Carolina, in accordance with NC DENR Land Application (503) Permit
WQ0001793 and in South Carolina in accordance with SC DHEC Land Application of Domestic
Sludge Permit ND0084883. One hundred seventy-seven of the acres in North Carolina are on
City owned land at the Resource Recovery Farm and the remainder is private farmland.

• RE: NPDES Permit Renewals for Two Rivers Utilities'WWTPs included in the Lake Wylie TMDL
Long Creek Wastewater Treatment Plant(NPDES#NC0020184)
• Eagle Road Wastewater Treatment Plant(NPDES#NC0006033)
• Crowders Creek Wastewater Treatment Plant(NPDES#NC0074268)
Dear Mr.Templeton:
•
• The NPDES Permits for wastewater treatment plants owned by Two Rivers Utilities(TRU)are due for
renewal in 2015 (Long Creek WWTP(NC0020184)and Eagle Road WWTP(NC0006033)expire on
• 1/31/15 and Crowders Creek WWTP(NC0074268)expires on 8/31/151. All three TRU wastewater
• facilities are part of the Lake Wylie TMDL for Total Nitrogen (TN) and Total Phosphorus(TP).
• TRU has built and operated modern nutrient removal processes which have greatly reduced nutrient
loads to the Lake Wylie watershed. Through regionalization efforts by TRU,five non-nutrient removal
• treatment plants have been taken out of service. Projects that will decommission three more non-
nutrient removal facilities are underway. This wastewater is or will be treated at one of TRU's nutrient
removal facilities,further reducing the nutrient loads into the Lake Wylie watershed.
To help these regionalization efforts make practical and long-term financial sense for our utility,TRU is
requesting revisions to nutrient limits at its facilities with these permit renewals.
• TRU requests:
•
• • Allocations from the decommissioned facilities(whether specifically allocated or part of the
• non-point allocation)are transferred to the TRU facility that receives its wastewater(provided it
• discharges to the same arm).
• Instead of the current concentration limits,we request these allocations be presented in
• pounds/day mass load limits and that an aggregate/bubble limit be given to Long Creek WWTP
• and Eagle Road WWTP for Total Nitrogen (TN)and Total Phosphorus(TP).
• j
•

• History,
• All WWTP discharges are currently included in the Lake Wylie TMDL. When the TMDL was developed,
large plants(greater than 1.0 mgd)were given a specific allocation as part of the Lake Wylie TMDL,and
small plants(less than 1.0 mgd)were included in the non-point allocation.
• A summary of the decommissioned facilities is shown below:

• 4 Lake Wylie TMDL allocation
• The City of Gastonia's Catawba Creek WWTP was decommissioned and Its flow routed to the Long Creek
• WWTP. No request is being made at this time for the transfer of that TMDL allocation of 300 lbs/day of
• TN and 38 lbs/day of TP. However,since the flow is treated at the Long Creek WWTP,we wish to
document the decommissioning of that facility potentially made a major contribution to the overall
nutrient reduction in the Lake Wylie watershed.
• TRU and HDR staff met previously with DWR staff in Raleigh in August 2010 and August 2013 to discuss
• the renewal of the NPDES permits. Meeting minutes for both meetings were recorded and submitted to
• all attendees. During both of those meetings,as well as on subsequent phone conversations,the topic
of receiving"credit" in the form of a higher nutrient allocation in exchange for taking these smaller
WWTPs out of service was discussed. An aggregate/bubble limit for Long Creek WWTP and Eagle Road
WWTP for TN and TP was also discussed. DWR stated that both of these requests were reasonable, met
• the intent of the TMDL,and could be implemented in the next NPDES permit renewals.
Page 2 of 5

• Quantitative Justification:
• The Long Creek, Eagle Road,Stanley,McAdenville and Pharr Yarns wastewater treatment plants all
• discharge into the South Fork Arm in the Lake Wylie TMDL. The former Ranlo WWTP and both of High
Shoals'wastewater facilities,discharged into that arm as well. Since TRU operates both the Long Creek
WWTP and Eagle Road WWTP,we are requesting an aggregate or bubble mass load limit between the
two treatment facilities for TN and TP.
• While only the Long Creek WWTP and Eagle Road WWTP were given specific allocations in the TMDL,
• the otherfacilities were included in the non-point nutrient allocation. If these non-specifically allocated
facilities were discharging at 6 mg/L TN in the summer months and 12 mg/L TN in the winter months,
and 1 mg/L TP year-round,they would have the potential to discharge a combined total of 132 lbs/day
of TN and 15.5 lbs/day of TP. Since the Long Creek WWTP is receiving the flow from these facilities,we
request that these pounds be included in the aggregate allocation for Long Creek and Eagle Road
• WWTPs. The pounds are based on the limits they could potentially have received, not the higher
• concentrations that they were actually discharging.

Request
In summary,we request limitations for total nitrogen and total phosphorus expressed as follows:
LONG CREEK WWTP(NPDES#NC0020184)&EAGLE ROAD WWTP(NPDES#NC0006033)
Parameter Limits Monitoring Requirements
Monthly Weekly Daily Measurement 1 Sample Sample
. Average Average Maximum Frequency Type Location
. Total Nitrogen Annual Limit: Weekly Composite Effluent
• 564,439 pounds/years
Total Phosphorus ZayZJ
Weekly Composite Effluent
• Notes:
1. The annual limit will be the combined sum of the monthly mass loadings from both Long Creek WWTP
(NPDES#NC0020184)and Eagle Road WWTP(NPI)ES#NC0006033),and all decommissioned WWTPs.
2. Monthly average limit for Total Phosphorus is for the combined total of the discharge from Long Creek
WWTP(NPI)ES#NC0020184)and Eagle Road WWTP(NPI)ES#NC0006033),and all decommissloned
• WWTPs. This will be computed as the sum of the monthly averages in lbs/day from each discharge.
