*Based on permitted flows
Briefly describe the proposed permitting action and facility background.• The Town of Wilkesboro
initially applied for an NPDES permit renewal at 4.9 MGD for the Cub Creek WWTP on April 9, 2019.
The Division submitted an additional information request on January 21,2021 and worked with the Town
and their consultant engineers at HDR to ensure a complete package was submitted. During this time,the
Town and HDR informed the Division of plans to expand the plant due to flows experienced at the
facility reaching 80-90%of the plant's capacity,resulting in a sewer moratorium imposed on July 1,
2021. Prior to this imposition,the Division provided speculative limits for expanded flow tiers at 8.0
MGD and 10.0 MGD on October 28,2020. On January 21,2022,the Town submitted a request for
renewal with modification of their permit to add a 9.0 MGD expanded flow tier. The Division reviewed
Page 1 of 17

this request and supporting documentation and submitted an additional information request on July 21,
2022, asking for further justification of the 9.0 MGD flow request and reassessment of projected flows.
The Town and HDR submitted additional information and a revised modification request on September
27,2022,this time asking for 8.0 MGD and providing justification of this flow, including a letter from
their major industrial user,Tyson Foods, identifying future flow demand.
This facility serves a population of approximately 4,400 residents. The facility also accepts waste from 3
significant industrial users(SIUs) including 1 of which that is categorical(CIUs),via their pretreatment
program. Treated domestic and industrial wastewater is discharged via Outfall 001 into the Yadkin River,
a class C water in the Yadkin-Pee Dee River Basin. Outfall 001 is located approximately 8.3 miles
upstream of waters designated as WS-V waters.
In their modification request,the Town indicated that the treatment works is currently experiencing a
volume of approximately 0.8 MGD of 1/1. The Town also notes, "In 2018,WK Dickson conducted a
Wastewater System Asset Inventory and Condition Assessment of the Town of Wilkesboro's collection
and treatment system. This report identified the condition of every component of the system and
identified a risk and replacement priority. One of the key considerations that aided in the priority were
components that would decrease 1/1. As of today,the recommended replacement schedule is being
followed."
Sludge Disposal: Sludge is handled at the plant and disposed of at the landfill.

4. Instream Data Summary
Instream monitoring may be required in certain situations, for example: 1)to verify model predictions
when model results for instream DO are within 1 mg/l of instream standard at full permitted flow;2)to
verify model predictions for outfall diffuser; 3)to provide data for future TMDL;4)based on other
instream concerns. Instream monitoring may be conducted by the Permittee, and there are also
Monitoring Coalitions established in several basins that conduct instream sampling for the Permittee(in
which case instream monitoring is waived in the permit as long as coalition membership is maintained).
Is this facility a member of a Monitoring Coalition with waived instream monitoring(YIN): Y
Name of Monitoring Coalition: Yadkin-Pee Dee River Basin Association
If applicable, summarize any instream data and what instream monitoring will be proposed for this
permit action: The current permit requires instream monitoring for dissolved oxygen,temperature and
conductivity upstream at the bridge between North Wilkesboro and Wilkesboro and downstream 100
yards below the outfall. Instream sampling is conducted three times per week during the months of June,
July,August and September and once per week during the remainder of the year. The Town is a member
of the Yadkin-Pee Dee River Basin Association(YPDRBA) and their instream requirements are
provisionally waived as long as they maintain membership. YPDRBA does not have any monitoring
stations upstream of the discharge. There are three Ambient Monitoring System stations upstream in the
W. Kerr Scott Reservoir,but each is inactive. While no upstream monitoring station exists,YPDRBA
station Q0450000 exists approximately 1 mile downstream of the outfall. Downstream data from June
2019-June 2023 are summarized in Table 2,below.

As the receiving stream is listed in the 2022 303(d)list as impaired for pH, instream pH monitoring has
been added to the permit. As the segment of the Yadkin River to which the Town discharges comprises
part of the headwaters of High Rock Lake,which is impaired for chlorophyll a and turbidity,instream
monitoring for turbidity, total nitrogen(TKN+NO2+NO3), ammonia and total phosphorous monitoring
has been added to the permit. Additionally, as WS-V waters exist approximately 8.3 miles below the
discharge and facility has reported multiple fecal coliform limit violations, instream fecal coliform
monitoring has been added to the permit.
As the facility is pursuing expansion and considering the stream impairment for pH,tracking effluent
impact on the receiving stream is critical. As such,the provisional waiver for instream monitoring has
been revised and is only applicable if the YPDRBA conducts representative upstream sample collection.
Instream sampling is to be conducted by Town of Wilkesboro in the event that YPDRBA does not
accomplish the necessary revisions for conducting sampling that is representative of this facility's
discharge. Additionally,the upstream monitoring location identified in the permit has been revised to the
Yadkin River at Wilkesboro Blvd,just below Reddies River and 0.5 miles above the outfall. See Figure 1
below for a map of monitoring locations.

5. Compliance Summary
Summarize the compliance record with permit effluent limits (past 5 years): In 2019,the facility reported
2 fecal coliform, 1 flow, 1 ammonia and 1 TSS limit violation resulting in Notices of Violation(NOVs),
as well as 1 ammonia and 1 TSS limit violation resulting in a Notice of Deficiency(NOD). The facility
reported 1 fecal coliform, 3 flow, and 1 TSS limit violations resulting in NODs and 2 TSS limit violations
resulting in NOVs. In 2021,the facility reported 1 TSS and 2 ammonia limit violations resulting in NODS
and 1 TSS and 1 ammonia limit violation resulting in NOVs. The facility reported 4 ammonia limit
violations resulting in NOVs in 2022.
Summarize the compliance record with aquatic toxicity test limits and any second species test results
(past 5 years): The facility passed 15 of 15 quarterly chronic toxicity tests as well as 4 of 4 second species
toxicity tests from March 2020 to September 2023.
Summarize the results from the most recent compliance inspection: The last facility inspection conducted
in September 2023 reported that the facility was out of compliance with NPDES permit NC0021717. The
inspection report noted the following:
1. Many components of the POTW are out of service and have been for—3 years. (One mechanical
bar screen,the grit system, a surface aerator, digester, clarifier)
2. Overall the WWTP is having difficulty screening solids at headworks. The buildup of debris can
be seen past bar screen process. Ineffective screening can and will have impacts on post
headwork processes of WWTP.
3. Ongoing issues with DO levels in the aeration basin. DO readings are below 1.0 mg/1
4. Floating solids and scum in the pre-UV channel. POTW is using water hose to disperse scum.
However,the effluent is clear with no floating solids. The use of the water hose was noted during
the last inspection.
The facility upgrades included as part of the expansion construction will address the concerns at the
facility.
The last pretreatment compliance inspection conducted in September 2023 reported that the facility was
compliant with their pretreatment program.

6. Water Quality-Based Effluent Limitations (WQBELs)
Dilution and Mixing Zones
In accordance with 15A NCAC 213.0206,the following streamflows are used for dilution considerations
for development of WQBELs: 1Q10 streamflow(acute Aquatic Life); 7Q10 streamflow(chronic Aquatic
Life;non-carcinogen HH); 30Q2 streamflow(aesthetics); annual average flow(carcinogen,HH).
If applicable, describe any other dilution factors considered(e.g., based on CORMIX model results):NA
If applicable, describe any mixing zones established in accordance with 15A NCAC 2B.0204(b): NA
Oxygen-Consuming Waste Limitations
Limitations for oxygen-consuming waste(e.g., BOD) are generally based on water quality modeling to
ensure protection of the instream dissolved oxygen(DO)water quality standard. Secondary TBEL limits
(e.g., BOD=30 mg/1 for Municipals)may be appropriate if deemed more stringent based on dilution and
model results.
Ifpermit limits are more stringent than TBELs, describe how limits were developed: BOD limits are
secondary technology-based effluent limits(TBELs)based on the results of a 1992 Level B analysis and
later 1998 speculative limits provided for expansion to 6.6 MGD have been applied to the 4.9 MGD and
6.6 MGD flow tiers. BOD limits were developed for the requested 8.0 MGD flow tier in the October 2020
speculative limits provided by the Division by freezing the mass-loadings from the currently permitted
levels.
Ammonia and Total Residual Chlorine Limitations
Limitations for ammonia are based on protection of aquatic life utilizing an ammonia chronic criterion of
1.0 mg/l (summer)and 1.8 mg/1(winter). Acute ammonia limits are derived from chronic criteria,
utilizing a multiplication factor of 3 for Municipals and a multiplication factor of 5 for Non-Municipals.
Limitations for Total Residual Chlorine(TRC) are based on the NC water quality standard for protection
of aquatic life(17 ug/1) and capped at 28 ug/l(acute impacts). Due to analytical issues,all TRC values
reported below 50 ug/1 are considered compliant with their permit limit.
Describe any proposed changes to ammonia and/or TRC limits for this permit renewal: TRC limits and
monitoring requirements were removed from the permit as the facility uses UV disinfection. However, in
the event of an emergency where chlorination is required as a backup or temporary means of disinfection
at the facility, a TRC limit and monitoring requirement have been added back into the permit based on the
review in the attached WLA spreadsheet. Please note that TRC monitoring is only required in the event
that chlorine is used at the plant and as part of the regular Effluent Pollutant Scans.
The current ammonia limits for both the 4.9 MGD and 6.6 MGD flow tiers were implemented in the
permit based on toxicity-based calculations. Ammonia-nitrogen limits have been reviewed in the attached
WLA and have been found to be protective.No changes are proposed to ammonia limits at these tiers. An
additional 8.0 MGD flow tier has been incorporated in the permit with summer ammonia limits of 13.3
mg/L and 35.0 mg/L based on the October 2020 Speculative limits provided by the Division. These limits
have been reviewed in the attached WLA and found to be protective.
Reasonable Potential Analysis(RPA)for Toxicants
If applicable, conduct RPA analysis and complete information below.
The need for toxicant limits is based upon a demonstration of reasonable potential to exceed water quality
standards, a statistical evaluation that is conducted during every permit renewal utilizing the most recent
effluent data for each outfall. The RPA is conducted in accordance with 40 CFR 122.44(d) (i). The NC
RPA procedure utilizes the following: 1)95% Confidence Level/95%Probability; 2)assumption of zero
Page 7 of 17

background; 3)use of%detection limit for"less than"values; and 4) streamflows used for dilution
consideration based on 15A NCAC 2B.0206. Effective April 6,2016,NC began implementation of
dissolved metals criteria in the RPA process in accordance with guidance titled NPDES Implementation of
Instream Dissolved Metals Standards, dated June 10,2016.
A reasonable potential analysis was conducted on effluent toxicant data collected between June 2019
through November 2023 Pollutants of concern included toxicants with positive detections and associated
water quality standards/criteria. Based on this analysis,the following permitting actions are proposed for
this permit:
• Effluent Limit with Monitoring. The following parameters will receive a water quality-based
effluent limit(WQBEL) since they demonstrated a reasonable potential to exceed applicable
water quality standards/criteria: Total Selenium(all flow tiers)
• Monitoring Only. The following parameters will receive a monitor-only requirement since they
did not demonstrate reasonable potential to exceed applicable water quality standards/criteria,
but the maximum predicted concentration was>50%of the allowable concentration: N/A
• No Limit or Monitoring: The following parameters will not receive a limit or monitoring, since
they did not demonstrate reasonable potential to exceed applicable water quality
standards/criteria and the maximum predicted concentration was<50%of the allowable
concentration: Total Arsenic, Total Cadmium, Total Chromium,Total Copper,Total Lead, Total
Molybdenum, Total Nickel,Total Silver,Total Zinc
• POTW Effluent Pollutant Scan Review: Three effluent pollutant scans were evaluated for
additional pollutants of concern.
o The following parameter(s)will receive a water quality-based effluent limit(WQBEL)
with monitoring, since as part of a limited data set,two samples exceeded the allowable
discharge concentration: N/A
o The following parameter(s)will receive a monitor-only requirement, since as part of a
limited data set, one sample exceeded the allowable discharge concentration: N/A
o The following parameters will not receive a limit or monitoring, since they did not
demonstrate reasonable potential to exceed applicable water quality standards/criteria and
the maximum predicted concentration was<50%of the allowable concentration: Total
Beryllium, Total Cyanide, Total Dissolved Solids,Nitrate (assessed using Nitrate+
Nitrite data)
As the discharge is approximately 8.3 miles above WS-V waters,WS standards were considered in the
review.No detections of chlorinated phenolic compounds were reported in the submitted effluent
pollutant scans. While effluent total hardness was reported at levels greater than 100 mg/L during the
period reviewed,the IWC is low enough, even at the highest flow tier,that no impact is anticipated.
Nitrate+Nitrite data from the submitted effluent pollutant scans were used to assess the WS Nitrate
standard.No reasonable potential for excursions above the WS standard were observed for Nitrate.
The 2020-2022 Surface Water Triennial Review proposed several amendments to the 15A NCAC 2B
.0200 rules,including changes to the freshwater dissolved selenium standard,which has been adopted
into rule. The facility discharges to lotic waters and a dissolved selenium standard of 3.1 µg/L has been
applied. The data available are for total selenium and the new standard is for dissolved selenium. At
present,no translator exists for dissolved to total selenium in freshwater. The EPA Form 2A NPDES
application requires selenium be reported for the application as"total recoverable,"which is reflected in
the Effluent Pollutant Scan special condition of the permit.Additionally,the acute criterion applied for
selenium is for total selenium,not dissolved. Until a translator is identified for dissolved to total selenium,
a translator of 1.0 is assumed and total selenium data will be collected and applied against the dissolved
and total selenium limits in the permit. Based on the RPA assessment, limits and monthly monitoring
have been added at all flow tiers.

If applicable, attach a spreadsheet of the RPA results as well as a copy of the Dissolved Metals
Implementation Fact Sheet for freshwater/saltwater to this Fact Sheet. Include a printout of the RPA
Dissolved to Total Metal Calculator sheet if this is a Municipality with a Pretreatment Program.
Toxicity Testing Limitations
Permit limits and monitoring requirements for Whole Effluent Toxicity(WET)have been established in
accordance with Division guidance(per WET Memo, 8/2/1999). Per WET guidance, all NPDES permits
issued to Major facilities or any facility discharging"complex"wastewater(contains anything other than
domestic waste)will contain appropriate WET limits and monitoring requirements,with several
exceptions. The State has received prior EPA approval to use an Alternative WET Test Procedure in
NPDES permits,using single concentration screening tests,with multiple dilution follow-up upon a test
failure.
Describe proposed toxicity test requirement: The permit requires quarterly chronic toxicity testing at
3.7%effluent concentration at 4.9 MGD, 5.0%effluent concentration at 6.6 MGD.No changes are
proposed for these flow tiers. Quarterly chronic toxicity testing at 6.0%effluent concentration at 8.0
MGD has been added to the permit. Please note that the toxicity IWC provided in the October 28, 2020
included a rounding error which has been corrected for the final permit.
Mercury Statewide TMDL Evaluation
There is a statewide TMDL for mercury approved by EPA in 2012. The TMDL target was to comply
with EPA's mercury fish tissue criteria(0.3 mg/kg) for human health protection. The TMDL established a
wasteload allocation for point sources of 37 kg/year(81 lb/year), and is applicable to municipals and
industrial facilities with known mercury discharges. Given the small contribution of mercury from point
sources(^2%of total load),the TMDL emphasizes mercury minimization plans (MMPs)for point source
control. Municipal facilities>2 MGD and discharging quantifiable levels of mercury(>1 ng/1)will
receive an MMP requirement. Industrials are evaluated on a case-by-case basis, depending if mercury is a
pollutant of concern. Effluent limits may also be added if annual average effluent concentrations exceed
the WQBEL value (based on the NC WQS of 12 ng/1) and/or if any individual value exceeds a TBEL
value of 47 ng/l.

TBEL,n /L 47
WQBEL,n /L 321.68 @ 4.9 MGD,241.91 @ 6.6 MGD, 201.7 @ 8.0 MGD
Describe proposed permit actions based on mercury evaluation: Since no annual average mercury
concentration exceeded the WQBEL, and no individual mercury sample exceeded the TBEL,no mercury
limit is required. Since the facility is >2 MGD and reported multiple detections(> 1 ng/L), a mercury
minimization plan(MMP) is required. The MMP requirement will be maintained.
Other TMDL/Nutrient Management Strategy Considerations
If applicable, describe any other TMDLs/Nutrient Management Strategies and their implementation
within this permit: The segment of the Yadkin River to which the Town discharges comprises part of the
headwaters of High Rock Lake,which is impaired for chlorophyll-a and turbidity. A TMDL is currently
in development for High Rock Lake. Per Session Law 2005-190 Senate Bill 981, "If the Environmental
Management Commission determines either that water quality in all or in any part of a drinking water
supply reservoir to which this section applies does not meet current water quality standards or that it is
likely that water quality will not meet water quality standards at any time prior to 1 July 2010, the
Commission shall not make any new or increased nutrient loading allocation to any person who is
Page 9 of 17

required to obtain a permit under G.S. 143-215 for an individual wastewater discharge directly or
indirectly into that reservoir. This limitation on new or increased nutrient loading allocation shall not be
construed to prohibit a person who holds a permit for a wastewater discharge into a drinking water supply
reservoir from purchasing a nutrient loading allocation from another person who holds a permit for a
wastewater discharge into the same drinking water supply reservoir."
As the Town has requested modification to their permit to incorporate an additional 8.0 MGD expanded
flow tier, and as explained in the October 28,2020 Speculative Effluent Limits letter, Total Nitrogen
(TN) and Total Phosphorus(TP)mass-loading have been added to the permit for the 8.0 MGD flow tier,
held to current discharge levels based on the last three years annual average (2017-2020). These limits
may change based on rulemaking, adoption of a High Rock Lake TMDL, or other nutrient strategy
implemented in the future. Total monthly flow reporting and a special condition have been added to the
permit outlining how annual nutrient loading is to be calculated.
The effluent limitations provided in the 2020 speculative limits letter are provided Table 4, shown below.

The High Rock Lake nutrient reopener special condition has been maintained in the permit.
See Toxicity Testing Limitations for more information regarding the chronic toxicity requirements.
Other WQBEL Considerations
If applicable, describe any other parameters of concern evaluated for WQBELs:
The current permit has Oil&Grease(O&G)requirements of a 30.0 mg/L monthly average limit and 45.0
mg/L weekly average limit with monthly monitoring,based on BPJ. O&G is a parameter of concern in
the pretreatment program,based in part on its regulation in the Industrial User Permits for the SIU Tyson
Farms,which has O&G limits. Based on review of the data, consistent compliance with permit limits, and
that O&G is being tracked through the pretreatment program, O&G limits and monitoring have been
removed from the permit.
As required by Session Law 2018-5, Senate Bill 99, Section 13.1(r), every applicant shall submit
documentation of any additional pollutants for which there are certified methods with the permit
application if their discharge is anticipated. The Town of Wilkesboro informed the Division that no
monitoring for additional pollutants has been conducted(see attached chemical addendum)and therefore
Page 10 of 17

no additional pollutants of concern have been identified in their effluent. However,the Town has
conducted and reported to the Division sampling conducted at the 2 landfills from which the Cub Creek
WWTP accepts wastewater. One analysis was conducted at each landfill for a suite of PFAS compounds
and 1,4-dioxane. While the 1,4-dioxane samples came back as non-detected, a number of PFAS
compounds were identified in the leachate at both landfills.
As only 2 samples were collected,one from each of the 2 landfills, additional analysis of 1,4-dioxane at
the Cub Creek WWTP,which discharges approximately 8.3 miles upstream of WS-V waters, is
warranted. Quarterly effluent monitoring of 1,4-dioxane and a 1,4-dioxane permit reopener has been
added to the permit. After a 24-month sampling period,the Permittee may request the Division conduct a
review of submitted data for assessment and approval of a 1,4-dioxane monitoring frequency reduction
from quarterly to annually.Note that,based on an AAF of 682 cfs and the WS ISTV of 0.35 µg/L,the
allowable discharge concentrations for 1,4-dioxane at this facility are 31.7 µg/L,23.6 µg/L and 19.6 µg/L
for the 4.9 MGD, 6.6 MGD and 8.0 MGD flow tiers,respectively.
As the facility has identified PFAS compounds in its effluent and discharges approximately 8.3 miles
upstream of WS-V waters, influent and effluent PFAS monitoring has been added to the permit at a
quarterly frequency. EPA Method 1633 was finalized on January 31, 2024. However, the methodology
has yet to be published in the Federal Register. Sampling using the method shall take effect the first full
calendar quarter following 6 months after the effective date of the permit to provide the Permittee time to
select a laboratory, develop a contract, and begin collecting samples. Effective 6 months after EPA has
the method in 40 CFR 136 published in the Federal Register,the Permittee shall conduct influent and
effluent monitoring using the approved Method 1633.
If applicable, describe any special actions (HQW or ORW) this receiving stream and classification shall
comply with in order to protect the designated waterbody: NA
If applicable, describe any compliance schedules proposed for this permit renewal in accordance with
15A NCAC 2H.0107(c)(2)(B), 40CFR 122.47, and EPA May 2007 Memo: NA
If applicable, describe any water quality standards variances proposed in accordance with NCGS 143-
215.3(e) and 15A NCAC 2B.0226 for this permit renewal:NA
7. Technology-Based Effluent Limitations (TBELs)
Municipals (if not applicable, delete and skip to Industrials)
Are concentration limits in the permit at least as stringent as secondary treatment requirements (30 mg/l
BODS/TSS for Monthly Average, and 45 mg/l for BODS/TSS for Weekly Average). YES
If NO,provide a justification for alternative limitations (e.g., waste stabilization pond). NA
Are 85%removal requirements for BOD51TSS included in the permit? YES
If NO,provide a justification (e.g., waste stabilization pond). NA
8. Antidegradation Review (New/Expanding Discharge):
The objective of an antidegradation review is to ensure that a new or increased pollutant loading will not
degrade water quality. Permitting actions for new or expanding discharges require an antidegradation
review in accordance with 15A NCAC 213.0201. Each applicant for a new/expanding NPDES permit
must document an effort to consider non-discharge alternatives per 15A NCAC 2H.0105(c)(2). In all
cases, existing instream water uses and the level of water quality necessary to protect the existing use is
maintained and protected.
If applicable, describe the results of the antidegradation review, including the Engineering Alternatives
Analysis (EAA) and any water quality modeling results: The proposed expansion is subject to review
under the State of North Carolina Environmental Policy Act(SEPA). A Finding of No Significant Impact
(FONSI)was issued on January 29,2024.
Page 11 of 17

An Engineer's Alternatives Analysis (EAA)was submitted by HDR,the consulting firm hired by the
Town of Wilkesboro, on January 21, 2022. The Division reviewed this EAA and supporting
documentation and submitted an additional information request on July 21,2022, asking for further
justification of the 9.0 MGD flow request and reassessment of projected flows. The Division noted
specifically the approximated 1.5 MGD of I/I that is being experienced in the system. The Town and
HDR submitted additional information and a revised modification request on September 27,2022,this
time asking for 8.0 MGD and providing justification of this flow, including a letter from their major
industrial user,Tyson Foods, identifying future flow demand. The Town also noted that efforts to
mitigate I/I will be undertaken alongside the expansion of the facility. After reviewing the revised request
and analysis,Division staff concurred with the projected flow justification as well as the alternatives
analysis. Division staff concurred with the projected flow needs based on a 20-year planning horizon. The
Cub Creek WWTP treats wastewater for a population of approximately 66,000 residents. While Wilkes
County has demonstrated a slight decrease in population from 2010—2022,the Town's residential status
has remained relatively consistent over the same time period. The flow projections provided by HDR
incorporate the expected municipal demand based on the population projections as well as the industrial
demand,which considers both the noted growth at Tyson Foods and anticipated additional industries.
HDR projects demand out to 2042. Division staff concurs with the modelled growth provided by HDR as
it is consistent with the 2010—2020 North Carolina Office of State Budget and Management population
growth extrapolated out to 2040, and the Town has provided written correspondence of plans to expand
production at Tyson Foods.
The following alternatives were evaluated for the expanded flow:
Alternative Description Total Cost
No Action. N/A
Connection to an Existing WWTP $494,600,000
Land Application $146,786,688
Wastewater Reuse Not viable—consumption demand of nearby facilities is insufficient
Expansion of facility $68,769,086 calculated as 20- ear Net Present Value
Connection to an Existing WWTP: The Town of Wilkesboro would convey approximately 12.3 MGD
of peak flows(4.1 MGD of max month flows)to another WWTP according to 20-year projected growth
in the service area. The closest facility to the Town of Wilkesboro is the North Wilkesboro WWTP. The
North Wilkesboro WWTP has 2.0 MGD of permitted capacity. The plant currently utilizes 1.2 MGD and
has 0.8 MGD of available plant capacity. It would not be feasible therefore to construct a force main to
the Town of North Wilkesboro since North Wilkesboro's plant would be able to provide only about one-
quarter of the needed capacity in Wilkesboro. The next closest facility that would have the capacity to
treat Wilkesboro's additional flows would be in Winston-Salem,NC. Winston-Salem/Forsyth County
Utilities operates two wastewater treatment facilities: the Archie Elledge WWTP and the Muddy Creek
WWTP with capacities of 30 MGD and 21 MGD,respectively. The cost estimate provided for this
alternative considers approximately 307,000 linear feet of 24-inch ductile iron pipe. The total cost,
including standard fees was estimated at approximately$494,600,000.
Land Application: The closest substantial facility to Wilkesboro that land applies to similar soils in the
project area is the Weyerhaeuser facility in Surry County. The Weyerhaeuser land application rates and
ratio of usable to unusable area was used to determine the amount of overall land needed to be purchased
by Wilkesboro for a land application alternative. Weyerhaeuser loading rates associated with older fields
that may have been damaged by past land management practices (those listed as 20 in/yr)were not
considered in estimating a loading rate for Wilkesboro. A loading rate of 31.8 in/yr was used for
Wilkesboro based on Fields A,B, CN, and CS. The Town also provided land application sites and limits
from permits for Wayne Farms,LLC(WQ0009826),Venture Properties,LLC (WQ0029195), and Kotis
Page 12 of 17

Properties,Inc. (WQ0013808),which are all smaller facilities. All the soils for these permits are soils
from the piedmont/upper piedmont. Loading rates in these permits vary between 12 to 52 inches per
year. While a few fields are rated higher in these permits than 31.8 inches per year,many are also
permitted for a lower rate. For a general evaluation of this alternative, a loading of approximately 30
inches per year seems reasonable. To determine the needed acreage Wilkesboro would need to purchase
to obtain an effective irrigatable 3,800 acres, a polygon was created around the spray fields associated
with the Weyerhaeuser permit. Even though this probably does not reflect the nature of putting together
thousands of acres across multiple parcels of land, it provides the necessary multiplier for screening
purposes to see if further analysis is needed. That is, it is likely Wilkesboro would require multiple sites
that would increase unusable areas versus the single site at Weyerhaeuser. The polygon around the
Weyerhaeuser site is approximately 70 acres. Given the loading rates and accounting for unusable
acreage, it is estimated Wilkesboro would need more than 10,700 acres. A sample of land costs for larger
parcels in Wilkes County was approximately$6,200 per acre. This likely undervalues land as there are
not many large parcels near Wilkesboro and the town would need to buy smaller parcels with structures
that would dictate a higher price.Nonetheless,this would put the entire land application costs of the entire
8 MGD facility to approximately$147 million.
Wastewater Reuse: Wastewater reuse was deemed an infeasible option since consumption demand of
nearby facilities is insufficient for the treated effluent from the Cub Creek WWTP.
Direct Discharge to Surface Waters: The total construction cost to expand the Cub Creek WWTP to 8.0
MGD is approximately$60 million not including soft costs associated with the project. The most
economically feasible and chosen option was the expansion of the Cub Creek WWTP. The Division
has reviewed the alternatives and concurs with this decision.
9. Antibacksliding Review:
Sections 402(o)(2) and 303(d)(4)of the CWA and federal regulations at 40 CFR 122.44(1)prohibit
backsliding of effluent limitations in NPDES permits. These provisions require effluent limitations in a
reissued permit to be as stringent as those in the previous permit,with some exceptions where limitations
may be relaxed(e.g.,based on new information, increases in production may warrant less stringent TBEL
limits, or WQBELs may be less stringent based on updated RPA or dilution).
Are any effluent limitations less stringent than previous permit(YES/NO): YES
If YES, confirm that antibacksliding provisions are not violated: The current permit has monthly average
and weekly average limits for oil and grease based on previous history with the parameter due to an
industrial user. During the period reviewed(past 4.5 years),the facility has only reported 3 detections of
oil and grease, once at 6 mg/L and twice 5 mg/L. Additionally,no permit violations have been issued for
oil and grease during the period reviewed. As such,the permit limits and monitoring requirements have
been removed.
10. Monitoring Requirements
Monitoring frequencies for NPDES permitting are established in accordance with the following
regulations and guidance: 1) State Regulation for Surface Water Monitoring, 15A NCAC 2B.0500;2)
NPDES Guidance,Monitoring Frequency for Toxic Substances(7/15/2010 Memo); 3)NPDES Guidance,
Reduced Monitoring Frequencies for Facilities with Superior Compliance(10/22/2012 Memo); 4)Best
Professional Judgement(BPJ). Per US EPA(Interim Guidance, 1996),monitoring requirements are not
considered effluent limitations under Section 402(o)of the Clean Water Act, and therefore anti-
backsliding prohibitions would not be triggered by reductions in monitoring frequencies.
For instream monitoring,refer to Section 4.
Page 13 of 17

Based on discussion with the DWR Basin Planning Branch,to support planning efforts,and as the two
parameters are used in calculating TN,monthly monitoring and reporting for TKN and NO2+NO3 has
been added to the permit.
11. Electronic Reporting Requirements
The US EPA NPDES Electronic Reporting Rule was finalized on December 21,2015. Effective
December 21, 2016,NPDES regulated facilities are required to submit Discharge Monitoring Reports
(DMRs) electronically. While NPDES regulated facilities would initially be required to submit additional
NPDES reports electronically effective December 21, 2020,EPA is proposing to extend this deadline
from December 21,2020,to December 21,2025. This permit contains the requirements for electronic
reporting, consistent with Federal requirements. The current compliance date will be extended if the
implementation date is extended as a final regulation change in the federal register.

NPDES Implementation of Instream Dissolved Metals Standards-Freshwater Standards
The NC 2007-2015 Water Quality Standard(WQS)Triennial Review was approved by the NC
Environmental Management Commission(EMC)on November 13,2014. The US EPA subsequently
approved the WQS revisions on April 6,2016,with some exceptions. Therefore,metal limits in draft
permits out to public notice after April 6,2016 must be calculated to protect the new standards - as
approved.

standards for Mercury and selenium are still expressed as Total Recoverable Metals due to
bioaccumulative concerns (as are all human health standards for all metals). It is still necessary
to evaluate total recoverable aquatic life and human health standards listed in 15A NCAC
2B.0200(e.g., arsenic at 10 µg/1 for human health protection; cyanide at 5 µg/L and fluoride at
1.8 mg/L for aquatic life protection).

General Information on the Reasonable Potential Analysis (RPA)
The RPA process itself did not change as the result of the new metals standards. However, application of
the dissolved and hardness-dependent standards requires additional consideration in order to establish the
numeric standard for each metal of concern of each individual discharge.
The hardness-based standards require some knowledge of the effluent and instream(upstream)hardness
and so must be calculated case-by-case for each discharge.
Metals limits must be expressed as `total recoverable' metals in accordance with 40 CFR 122.45(c). The
discharge-specific standards must be converted to the equivalent total values for use in the RPA
calculations. We will generally rely on default translator values developed for each metal(more on that
below),but it is also possible to consider case-specific translators developed in accordance with
established methodology.
RPA Permitting Guidance/WOBELs for Hardness-Dependent Metals -Freshwater
The RPA is designed to predict the maximum likely effluent concentrations for each metal of concern,
based on recent effluent data, and calculate the allowable effluent concentrations,based on applicable
standards and the critical low-flow values for the receiving stream.
If the maximum predicted value is greater than the maximum allowed value(chronic or acute),the
discharge has reasonable potential to exceed the standard,which warrants a permit limit in most cases. If
monitoring for a particular pollutant indicates that the pollutant is not present(i.e. consistently below
detection level),then the Division may remove the monitoring requirement in the reissued permit.
1. To perform a RPA on the Freshwater hardness-dependent metals the Permit Writer compiles the
following information:
• Critical low flow of the receiving stream, 7Q10(the spreadsheet automatically calculates
the 1 Q 10 using the formula 1 Q 10=0.843 (s7Q 10, cfs)0.993
• Effluent hardness and upstream hardness, site-specific data is preferred
• Permitted flow
• Receiving stream classification
2. In order to establish the numeric standard for each hardness-dependent metal of concern and for
each individual discharge,the Permit Writer must first determine what effluent and instream
(upstream)hardness values to use in the equations.
The permit writer reviews DMR's,Effluent Pollutant Scans, and Toxicity Test results for any
hardness data and contacts the Permittee to see if any additional data is available for instream
hardness values,upstream of the discharge.
If no hardness data is available,the permit writer may choose to do an initial evaluation using a
default hardness of 25 mg/L(CaCO3 or(Ca+Mg)). Minimum and maximum limits on the
hardness value used for water quality calculations are 25 mg/L and 400 mg/L,respectively.
If the use of a default hardness value results in a hardness-dependent metal showing reasonable
potential,the permit writer contacts the Permittee and requests 5 site-specific effluent and
upstream hardness samples over a period of one week. The RPA is rerun using the new data.

Permit No. NCO021717
The overall hardness value used in the water quality calculations is calculated as follows:
Combined Hardness(chronic)
_(Permitted Flow,cfs *Avg. Effluent Hardness,mg/L)+s7Q10, cfs *Avg. Upstream Hardness,mg/L)
(Permitted Flow,cfs+s7Q10,cfs)
The Combined Hardness for acute is the same but the calculation uses the IQ 10 flow.
3. The permit writer converts the numeric standard for each metal of concern to a total recoverable
metal,using the EPA Default Partition Coefficients(DPCs)or site-specific translators, if any
have been developed using federally approved methodology.
EPA default partition coefficients or the"Fraction Dissolved"converts the value for
dissolved metal at laboratory conditions to total recoverable metal at in-stream
ambient conditions. This factor is calculated using the linear partition coefficients
found in The Metals Translator: Guidance for Calculating a Total Recoverable
Permit Limit from a Dissolved Criterion (EPA 823-B-96-007, June 1996)and the
equation:
Cdiss - 1
Ctotal I + { [Kpo] [ss('+a)] [10-6] }
Where:
ss=in-stream suspended solids concentration [mg/1],minimum of 10 mg/L used,
and
Kpo and a=constants that express the equilibrium relationship between dissolved
and adsorbed forms of metals. A list of constants used for each hardness-dependent
metal can also be found in the RPA program under a sheet labeled DPCs.
4. The numeric standard for each metal of concern is divided by the default partition coefficient(or
site-specific translator)to obtain a Total Recoverable Metal at ambient conditions.
In some cases,where an EPA default partition coefficient translator does not exist(ie. silver),the
dissolved numeric standard for each metal of concern is divided by the EPA conversion factor to
obtain a Total Recoverable Metal at ambient conditions. This method presumes that the metal is
dissolved to the same extent as it was during EPA's criteria development for metals. For more
information on conversion factors see the June, 1996 EPA Translator Guidance Document.
5. The RPA spreadsheet uses a mass balance equation to determine the total allowable concentration
(permit limits)for each pollutant using the following equation:
Ca=(s7Q 10+Qw)(Cwgs)—(s7Q 10) (Cb)
Qw
Where: Ca=allowable effluent concentration(µg/L or mg/L)
Cwqs=NC Water Quality Standard or federal criteria(µg/L or mg/L)
Cb=background concentration: assume zero for all toxicants except NH3* (µg/L or mg/L)
Qw=permitted effluent flow(cfs,match s7Q 10)
s7Q 10=summer low flow used to protect aquatic life from chronic toxicity and human
health through the consumption of water, fish, and shellfish from noncarcinogens (cfs)
* Discussions are on-going with EPA on how best to address background concentrations
Flows other than s7Q 10 may be incorporated as applicable:
IQ 10=used in the equation to protect aquatic life from acute toxicity
Page 3 of 4

Permit No. NC0021717
QA=used in the equation to protect human health through the consumption of water,
fish, and shellfish from carcinogens
30Q2=used in the equation to protect aesthetic quality
6. The permit writer enters the most recent 2-3 years of effluent data for each pollutant of concern.
Data entered must have been taken within four and one-half years prior to the date of the permit
application(40 CFR 122.21). The RPA spreadsheet estimates the 95th percentile upper
concentration of each pollutant. The Predicted Max concentrations are compared to the Total
allowable concentrations to determine if a permit limit is necessary. If the predicted max exceeds
the acute or chronic Total allowable concentrations,the discharge is considered to show
reasonable potential to violate the water quality standard, and a permit limit(Total allowable
concentration)is included in the permit in accordance with the U.S. EPA Technical Support
Document for Water Quality-Based Toxics Control published in 1991.
7. When appropriate,permit writers develop facility specific compliance schedules in accordance
with the EPA Headquarters Memo dated May 10,2007 from James Hanlon to Alexis Strauss on
40 CFR 122.47 Compliance Schedule Requirements.
8. The Total Chromium NC WQS was removed and replaced with trivalent chromium and
hexavalent chromium Water Quality Standards. As a cost savings measure,total chromium data
results may be used as a conservative surrogate in cases where there are no analytical results
based on chromium III or VI. In these cases,the projected maximum concentration(95th%) for
total chromium will be compared against water quality standards for chromium III and
chromium VI.
9. Effluent hardness sampling and instream hardness sampling,upstream of the discharge, are
inserted into all permits with facilities monitoring for hardness-dependent metals to ensure the
accuracy of the permit limits and to build a more robust hardness dataset.

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
On 9/8/2023 a Pretreatment Audit Inspection (PAI)was performed by Tricia Lowery of the
Winston-Salem Regional Office. Amber Garwood and Glenn Clark were present for the inspection.
The purpose of this audit was to determine the effectiveness of the Control Authority's pretreatment
program regarding SIU inspections., which includes the initial interview, tour of SIU facility, sampling
review, and an exit interview.
Background
This is a 4.9 MGD permitted facility. The Town has 3 Significant Industrial Users (SIUs), none of which
are categorical. The publicly owned treatment works (POTW) had 3 violations in July, August and
September of 2022 for Ammonia.
POTW Interview
The POTW is in the process of upgrading. The POTW has many issues removing solids, obtaining
proper DO levels in aeration basin and many components in the facility are out of service. Once
upgrades are complete, this will improve many elements of the pretreatment program.
Pretreatment Program Elements Review
The Headworks Analysis (HWA)was last approved on 4/27/2020. The next HWA is due 4/1/2024.
The IWS was last approved on 3/27/2020. The next IWS is due 12/1/2024.
The Sewer Use Ordinance (SUO)was approved on 1/2/2013.
The Enforcement Response Plan (ERP)was submitted on 2/24/2020 and approved on 3/14/2020.
The Long-Term Monitoring Plan (LTMP)was submitted 9/29/2020 and approved on 3/11/2021.
LTMP File Review
The Long-Term Monitoring Plan (LTMP) is being conducted at the proper locations and frequencies
(2/year).
Industrial User Permit (IUP) File Review
A review of the file for Tyson (IU#1003) revealed that the monitoring data was well organized and
compliant.
The slug control plan for Tyson (IU#1003)was in good order.
Action Items
No other action items were noted.

Good morning Nick,
I've summarized the information that you've asked for. I've copy and pasted your asks in red and my responses in black.
1. Sorry for the quick follow-up, but would you also look into the February 2022 influent TSS and BOD data from the
plant?1 just want to make sure I'm not crazy, but both parameters come in quite low for that month and are
skewing the 85%removal rate requirement.
a. I've summarized the February 2022 monthly BOD and TSS data. As a reminder, since the Town has 2
influent sources,they generate a weighted influent based on flows. When asked about the February
2022 influent data,the Town let me know that Tyson's influent BOD of 20 mg/I was reported as a lab
error in the DMR.This value was still included in the spreadsheet that generated the averages listed
below. Once the Town removed the BOD lab transcription error, it changed the BOD averages to:Tyson
303 mg/l, and the weighted to 300 mg/l.There were no errors in the reporting of TSS. In the table below
I've summarized the data:
February 2022
Influent Source Monthly Average Monthly Average Monthly Average
Flow(MGD) BOD(mg/L) TSS(mg/L)
Municipal 0.6 280.2 236.3
Tyson Foods Influent 2.3 288.6 (303 with error 287.4
removed)
Weighted Average 2.9 289 (300 with error 274
Influent I I removed)
2. As required by Session Law 2018-5, Senate Bill 99, Section 13.1(r), every applicant shall now submit
documentation of any additional pollutants for which there are certified methods with the permit application if
their discharge is anticipated. The list of pollutants may be found in 40 CFR Part 136, which is incorporated by
reference. If there are additional pollutants with certified methods to be reported,please submit the Chemical
Addendum to NPDES Application table with your application and, if applicable, list the selected certified
analytical method used. If no additional sampling was conducted and/or there are no additional pollutants to
report, please note as much on the form itself. This requirement applies to all NPDES facilities. The Chemical
Addendum to NPDES Application will be required for any type of facility with an NPDES permit, depending on
whether those types of pollutants are found in your wastewater. Please fill out, sign and submit the Chemical
Addendum to NPDES Application.
1

a. As of the most recent priority pollutant analysis (2022)the Town did not report any new industrial
contributors. Both the filled out chemical addendum and priority pollutant scan are attached.
3. When you have sometime, please send me the 3 total mercury sample results that were used to summarize total
mercury in Table C of the revised application. The DMRs have reported total mercury using a variety of PCS
codes, so I'm hesitant to use this for my evaluation.Additionally, I'm hesitant to use the PPA data since it's so old
(2016-2017).
a. The Town tests for mercury quarterly. Low level Mercury results are below and most recent lab reports
for mercury are attached.

Hi Lara,
Thank you so much for getting this info! To make our lives easier, emailing just the additional information is perfectly ok.
I can attach to the fact sheet as an addendum to the application if need be. This way we don't have to worry about
things getting lost in transit, and it's not like the entire application was affected.
Thanks,

Good morning Nick,
I've got all of the data that you've asked for clarification on. How should I get this information back to you?
Should I generate a new renewal application PDF with the excel sheet attached in the appendix as a PDF?And the same
thing as the mercury results and PPA?
Or, should I attach those items to you in a PDF without re-sending our renewal application?
Thank you,
Lara

I'm working through the renewal process for the Wilkesboro WRF currently and wanted to request the following:
• As required by Session Law 2018-5, Senate Bill 99, Section 13.1(r), every applicant shall now submit
documentation of any additional pollutants for which there are certified methods with the permit application if
their discharge is anticipated.The list of pollutants may be found in 40 CFR Part 136,which is incorporated by

FINDING OF NO SIGNIFICANT IMPACT
Article I, Chapter 113A of the North Carolina General Statutes requires an action to be subject to
the requirements of the North Carolina Environmental Policy Act(NCEPA) if it involves the
expenditure of public funds and if a potential impact is anticipated to the environment. The
project has been evaluated for compliance with the NCEPA and is determined to be a major
agency action, which will affect the environment.
Project Applicant: Town of Wilkesboro,North Carolina
Project Description: The proposed project will upgrade major components and
increase the capacity of the existing Wilkesboro Cub Creek
Wastewater Treatment Plant from 4.9 million gallons per day
(MGD) maximum month flow to 8 MGD maximum month flow.
Improvements will include upgraded influent pump station,
upgraded headworks, conversion of aeration basin to equalization
basin, influent buffering, addition of secondary treatment, tertiary
disk filtration, new UV disinfection system, new effluent flow
metering, improved aerobic digestion and thickening, replacement
of sludge dewatering unit, and a new operations building.
Project Number: CS370829-02 & SRP-W-0208
Project Cost: $72,000,000
Clean Water State $42,000,000
Revolving Loan Fund:
Wastewater State Reserve $18,000,000
Program:
Local Funds: $12,000,000
The review process indicated that significant adverse environmental impacts should not occur if
mitigative measures are implemented, and an environmental impact statement will not be
required. The decision was based on information in the Engineering Report/Environmental
Information Document (ER/EID) submitted by the applicant and reviews by governmental
agencies. The attached Environmental Assessment(EA),prepared by the Division based on the
ER/EID, supports this action and outlines mitigative measures that must be followed. This
Finding of No Significant Impact(FONSI) completes the environmental review record,which is
available for inspection at the State Clearinghouse.
No administrative action will be taken on the proposed project for at least 30 days after
notification that the FONSI has been published in the North Carolina Environmental Bulletin.

ENVIRONMENTAL ASSESSMENT
A. Proposed Facilities and Actions
The proposed project will upgrade major components and increase the capacity of the existing
Wilkesboro Cub Creek Wastewater Treatment Plant (WWTP) from 4.9 million gallons per day
(MGD)maximum month flow to 8 MGD maximum month flow. Improvements will include the
following components:
• Upgrade the influent pump station to increase the total pumping capacity of the municipal
flow.
• Retrofitted and upgrade the existing headworks including new screens and new grit
classifier.
• Convert the existing aeration basin to a wet weather flow equalization basin.
• Convert secondary clarifier 4 to an influent buffer tank to converge the municipal and
industrial flows upstream of secondary treatment and install pumps to convey the flow to
the biological treatment system.
• Upgrade secondary treatment by constructing three AquaNereda aerobic granular sludge
(AGS)tanks and converting secondary clarifier 3 to a dual sludge buffer(SB) and water
level correction(WLC) tank, which will serve to thicken the WAS before pumping to the
aerobic digesters; existing secondary clarifier 1 and 2,which are located in the
floodplain,will be decommissioned.
• A set of two tertiary disc filter may be installed as needed based on future nutrient
removal limits in the High Rock Lake basin.
• The existing UV system in the floodplain will be decommissioned, and a new UV
disinfection system will be installed outside of the floodplain.
• The existing effluent Parshall flume in the floodplain will be decommissioned, and a new
Parshall Flume will be constructed just downstream of the new UV disinfection system.
• The existing aerobic digesters will remain operational, and new disc thickening units will
be installed in 10 years or approximately by 2032. The timing of the disc thickening unit
is dependent on expected growth in the area and on the expenses of landfill tipping fees.
• The existing Huber Q-Press 800 sludge dewatering unit is nearing the end of its service
life and will be replaced with another unit of the same model. A second unit will be
installed to increase capacity.
• A new operations building will be constructed outside of the floodplain and near the
secondary treatment process for the plant operations staff.
Funding Status: The estimated total cost for the project is $72,000,000. The Town is applying for
a Clean Water State Revolving Fund(CWSRF) loan of$42,000,000 including $1,000,000 of
principal forgiveness and has been awarded a State Reserve Program (SRP) grant of
$18,000,000. The Town will fund the remainder of the project, including closing
costs/administrative fees of$1,110,0000,through local funds. The City may apply for additional
CWSRF funding.

B. Existiniz Environment
Topography and Soils. Wilkesboro is located in the Piedmont physiographic province. The
elevation of the project area ranges from 946 feet mean sea level (msl) to 1,038 feet msl.
Portions of the project site are located within the 100-year flood plain.
The project site includes the following soil units: Banister fine sandy loam, 1 to 6 percent slopes,
rarely flooded(BaB), moderately well drained or somewhat poorly drained soils; characterized
as strongly acidic; Codorus loam, 0 to 2 percent slopes, frequently flooded (CoA), consist of very
deep, moderately well drained and somewhat poorly drained soils; Dan River loam, 0 to 4
percent slopes, occasionally flooded(DaA)very deep, well drained soils, characterized as very
strongly acidic in the upper parts through slightly acidic in the lower parts; Danripple sandy clay
loam, 8 to 15 percent slopes, moderately eroded(DpC2), very deep, well drained soils,
characterized as very strongly acidic to moderately acidic; Fairview sandy loam, 15 to 25 percent
slopes (FaD), very deep,well drained soils, characterized as extremely acidic to moderately
acidic throughout; Fairview sandy clay loam, 8 to 15 percent slopes, moderately eroded(FcC2)
soils, similar to Fairview sandy loam located in less steep terrain; Fairview-Urban land complex,
2 to 15 percent slopes (FrC) soils, also similar to Fairview sandy loam typically including built
upon urban lands; and Rhodhiss fine sandy loam, 25 to 60 percent slope (RdE), very deep, well-
drained soil characterized by very strongly acidic to slight acidic throughout.
Surface Water. The project area is located in the Yadkin Headwaters Subbasin of the Yadkin-
Pee-Dee River Basin(HUC 0304010103). Surface waters in the area include Cub Creek, Little
Cub Creek, and the Yadkin River. All are rated Class C. Cub Creek is impaired for poor fish
community.
Water Soply. The Town's public water supply draws water from the Yadkin River.
C. Existing Wastewater Treatment Facilities
The Town owns and operates the Club Creek WWTP, which is an activated sludge plant with a
permitted capacity of 4.9 MGD under NPDES Permit Number NC0021717 discharging to the
Yadkin River. The WWTP was constructed in 1965 with various improvements made since
construction. The plant has been maintained in good condition overall but is nearing capacity.
Some service components are nearing the end of their useful life. The liquids train consists of an
influent pumping station, screening and grit removal, an aeration basin with surface mixers,
secondary clarification, and UV disinfection. The solids train consists of aerobic digestion,
dewatering by a Huber screw press, and landfilling of dewatered solids. The average daily
effluent flows in 2019 and 2020 were 4.44 MGD and 4.77 MGD, respectively. The WWTP
receives 70 to 80 percent of its flow from Tyson Foods, Inc., and the WWTP site contains
Tyson's influent pump station and two of Tyson's pretreatment basins. The 2021 current average
daily flow is 4.21 MGD, which is approximately 86% of the plant's permitted capacity. The
Town has received 22 Notices of Violations (NOVs) for effluent permit exceedances between
December 2016 and December 2021. Several components are located within the 100-year
floodplain.
2

In addition to the WWTP, the Town owns and operates a wastewater collection system
consisting of 67 miles of gravity sewer, 1,383 manholes, 10 miles of force main, and 13 pump
stations. An asset inventory and assessment study was recently completed including a 10-year
rehabilitation and replacement plan for the collection system.
D. Need for Proposed Facilities and Actions
The Town's existing WWTP is aging and under capacity. Upgrades are needed to replace aging
equipment, improve treatment, and provide additional capacity for anticipated demand. The
Town's NPDES Permit previously included requirements to monitor nutrients but did not specify
numerical nutrient limits. The speculative permit includes numerical limits for both TN and TP
which will require improved treatment, and the Town is experiencing industrial and commercial
growth.Nutrient limits to the Yadkin River may change depending on the final nutrient strategy
developed for High Rock Lake. The Town has received 22 Notices of Violations (NOVs) for
effluent permit exceedances between December 2016 and December 2021. In July 2021, the
Town received a Sewer Line Moratorium from NCDEQ. The moratorium was issued because in
the previous calendar year when the Town's effluent from the WWTP flow averaged 4.8 MGD
representing 97.2 percent of the plant's current treatment capacity.
The purpose of this proposed project there is to provide an upgraded and expanded facility that
will enable Wilkesboro to meet future permit limits while accommodating future growth.
E. Alternatives Analysis
No-Action: The No-action alternative would continue operation of the WWTP with aging
equipment, components located in the floodplain, exceeding flow limits, and unable to meet
future effluent water quality standards for total nitrogen and phosphorus. This alternative is
infeasible and was rejected.
Alternative 1 —AquaNereda Aerobic Granular Sludge (AGS) (Preferred): This alternative
consists of upgrading the secondary treatment process using an AquaNereda aerobic granular
sludge (AGS) system operating in three new sequencing batch reactors and increasing the
capacity of the WWTP from 4.9 MGD to 8 MGD. Associated improvements to the plant include
influent pump station upgrades, the existing headworks will be retrofitted and upgraded,
conversion of existing Clarifier No. 4 to an AGS influent buffer tank, construction of new tanks
required for the Nereda process, construction of a new UV disinfection system and effluent
measurement/monitoring facilities, and the addition of a new solids dewatering screw press. A
new operations building is also included in this alternative. The existing aerobic digesters will
remain in-use. This alternative is preferred because it meets the desired treatment flows for the
plant with the lowest treatment cost per gallon, greatest energy savings, and smallest spatial
footprint compared to other alternatives.
Alternative 2—Oxidation Ditch with Mobile Organic Biofilm Process: This alternative would
also upgrade treatment and increase the plant capacity using an oxidation ditch with Mobile
Organic Biofilm(MOB)process by Nuvoda. The oxidation ditch would be filled with Kenaf
3

media to enhance treatment and settling, and a media retention screen would be included to filter
out any wasted media and return it to the biological process. Associated plant upgrades would
include updates to the influent pump station,rehabilitation of existing headworks system,
construction of a new ultraviolet(UV) disinfection system, construction of a high river effluent
pump station, addition of a new effluent flow meter,upgrades to the existing RAS pump station,
and addition of a new solids dewatering unit. This alternative was rejected due to higher
treatment cost per gallon, higher energy demand, and larger spatial footprint compared to the
preferred alternative. Additionally,this alternative would include constructing new treatment
components within the floodplain.
Alternative 3 —Conventional Sequencing Batch Reactor(SBR): This alternative consists of a
conventional SBR system with four tanks located adjacent to the existing maintenance building.
Associated plant improvements would include upgrades to the influent pump station,
construction of new headworks north of Tyson's pretreatment basins, construction of a new UV
disinfection system, addition of a new effluent flow meter, and addition of new solids thickening
and dewatering units. A new plant operations/control building would also be included in this
alternative. This alternative was rejected due to higher treatment cost per gallon, higher energy
demand, and larger spatial footprint compared to the preferred alternative.
F. Environmental Consequences and Mitigative Measures
Topography and Soils: Significant impacts to topography and soils are not anticipated. The
WWPT site has already been disturbed. Minimal grading will be required. Total impervious area
will change from 14 percent to 17 percent. Disturbed areas that are not within building footprints
will be re-seeded after construction. Impacts to the floodplain will include removing and
demolishing the existing aeration basin and Tyson influent pump station, adding rock to existing
access roads, and temporary erosion control devices. There will be no permanent changes to
existing elevations within the 100-yea floodplain. The project will comply with local FEMA
regulations including appropriate permits. The project will expand the WWTP, and secondary
and cumulative impacts (SCI) are possible due to future wastewater lines and development in the
service area. These impacts will be minimized through adherence to Town of Wilkesboro and
Wilkes County ordinances addressing floodplain development, flood damage prevention, sewer
use, and watershed development.
Land Use: Significant impacts to land use are not anticipated. The project is located within sites
owned by the Town of Wilkesboro and Tyson Foods and used for wastewater treatment. SCI will
be managed through the Town's Comprehensive Land Use Plan, which includes provisions for
preserving open spaces.
Wetlands: Significant impacts to wetlands are not anticipated. There are no wetlands on the
project site and therefore no direct impacts anticipated. SCI related to future growth will be
minimized through the Wilkes County Watershed Ordinance, which limits certain development
and places impervious surface limits on certain developments to project wetlands and streams.
Important Farmlands: Significant impacts to important farmlands are not anticipated. The project
area does include soils designated as prime and unique farmland, but the site is already disturbed
4

and not in agricultural use. Potential SCI will be minimized through the NC Agricultural
Development and Farmland Preservation Fund, which promotes farmland preservation.
Public Lands and Scenic, Recreational, and State Natural Areas: Significant impacts to public
lands, scenic, recreational, or state natural areas are not expected. Parks and public lands in the
surrounding area may experience increase in noise during construction activities,but these
impacts will be minor and temporary.
Cultural Resources: Direct impacts to cultural and historic resources are not anticipated. The
Downtown Wilkesboro Historic District is located within a mile of the project area,but impacts
are not anticipated. Five previously recorded archaeological sites are located within one mile of
the project site and are not expected to be impacted due to construction activities occurring at
previously disturbed locations. The North Carolina State Historic Preservation Office (SHPO)
conducted a review of the project and is aware of no historic resources which will be impacted
by the project(July 29, 2022, ER 21-2531). Potential SCI will be minimized through
Wilkesboro's Historic Preservation Committee's guidelines.
Air Quality: No significant impacts to air quality are anticipated. Construction activities may
cause a temporary increase in emissions and will cease when construction is complete. Dust
control measures will be implemented, and open burning of materials will not be allowed.
Testing of emergency generators may cause temporary, short-term emissions. Otherwise, the
project will not result in new sources of air pollution. SCI to air quality are not anticipated.
Noise Levels: No significant noise impacts are anticipated. Noise from construction activities
will be temporary with construction hours restricted under the Town's Noise Ordinance.
Operational noise impacts may increase slightly as a result of additional components and new
technologies at the WWTP. Forested areas surrounding the project site create natural noise
buffers to minimize any noise for surrounding residences. SCI may include construction noise
for wastewater line installation and residential and industrial development. These impacts will be
minimized through compliance with Wilkes County's High Impact Land Use Ordinance.
Water Resources: No significant negative impacts to water resources are anticipated. A
sedimentation and erosion control plan will be implemented to minimize impacts to surface
water from construction activities. The project will provide a benefit to nearby surface waters by
removing several components from the floodplain and improving the treatment process and
qualify of effluent from the WWTP. SCI related to future develop will be minimized through the
Wilkes County Watershed Ordinance and stormwater provisions in the Town's Subdivision
Ordinance.
Forest Resources: Significant impacts to forest resources are not expected. The project site
includes scattered wooded areas. A small area of approximately 0.18 acre of upland forest will
be cleared. SCI from future development will be minimized through the Town's Tree,
Subdivision, and Zoning ordinance and Wilkes County Watershed Ordinance.
Shellfish or Fish and Their Habitats: Impacts to shellfish, fish, and their habitats are not expected
to be significant. There are no known occurrences of threatened or endangered aquatic species in
5

the project site or immediate surrounding area. Impacts to aquatic species from construction
activities will be minimized through adherence to a sediment and erosion control plan. Aquatic
species will benefit from improved wastewater effluent quality. SCI related to future develop
will be minimized through the Wilkes County Watershed Ordinance and stormwater provisions
in the Town's Subdivision Ordinance.
Wildlife and Natural Vegetation: No significant impacts to wildlife and natural vegetation are
expected. No threatened or endangered species have been identified within one mile of the
project site. Suitable habitat exists for the Northern long-eared bat and tricolored bat. To protect
these species, the recommendation from the U.S. Fish& Wildlife Service (USFWS)to avoid tree
removal between March 15th and November 15t1i will be followed. Impacts to other terrestrial
species are not anticipated. Most of the project is located in previously disturbed and maintained
areas. SCI related to future development will be minimized through County and Town
development ordinances.
Introduction of Toxic Substances: The project is not expected to introduce toxic substances into
the environment. Construction specifications will include provisions for fuel, oil, and lubricants
to be contained and equipment to be properly maintained to prevent leakage and spills.
Chemicals used on-site will be controlled and maintained as currently required at the WWTP.
The U.S. Fish and Wildlife Service was consulted and provided guidance (June 2, 2023). The
North Carolina Wildlife Resources Commission,Natural Heritage Program, and DWR Winston-
Salem Regional Office do not object to the proposed project. The U.S. Army Corps of Engineers
was consulted and did not object to the project. The North Carolina Department of Natural and
Cultural Resources is aware of no historic resources which will be impacted by the proposed
project(July 29, 2022, ER 21-2531).
G. Public Participation, Sources Consulted
The Town of Wilkesboro held a public meeting on November 6, 2023. The meeting included a
presentation about the proposed project and opportunity for public comments. The Town also
provided a 30-day period for submission of written comments. Comments at the meeting
included support for the project from a councilman and a question about publishing time. No
written comments were received.
The current user charge for a typical residential customer is $30.77 per month for sewer and
water combined,based on consumption of 5,000 gallons per month. The proposed project will
increase the bill by $9.62, for a future sewer bill of$40.39. The Town intends to raise rates
through a series of smaller annual increases.

3.Analysis
The samples were analyzed using Waters Acquity UPLC equipped with Xevo TQ MS (LC/MS/
MS "Fili" and "Kili").
For aqueous samples, the sample volume was measured gravimetrically by the laboratory, and
spiked with Extraction Standard (ES). The sample was then mixed well and centrifuged, if
needed. The samples were then extracted via SPE, and the extracts were cleaned up using
ENVI-Carb.
Each final sample extract was transferred to an autosampler vial, spiked with Injection Standard
(IS), and brought to a final volume of 400pL prior to analysis.
Samples were initially screened by direct inject by using a 120 uL aliquot fortified with ES and IS,
then analyzed to determine extraction volume.
Due to acquisition requirements for analytes requested, the sample was analyzed in more than
one sequence. Supplemental compounds were reported using a single point calibration forced
through zero.

4. Calibration
In the initial calibration, the reported analytes exhibited R A 2 of> 0.99. The reported analytes in
the calibration standards, continuing calibration (concal) and Initial Calibration Verification (ICV)
met the 30% accuracy criterion for native analytes.
5. QC Notes
Except where noted below, the QC sample analyses passed all method criteria.
QC samples that did not meet method acceptance criteria were:
OPR-12729-PFAS PFNS and PFTrDA fell above method critieria. These analytes were not
detected in the samples; therefore, the data is reported with no adverse impact.
OPR-12729-PFAS PFHpA, PFHxS, PFDA, and PFBS fell above method criteria in initial analysis
and confirmed upon reinjection. Samples were re-extracted and reported for these analytes.
The samples were extracted outside the 28-day from collection holding time and client has been
made aware and approved reporting as-is. The samples were analyzed within the 28-day from
extraction to analysis holding time required by the method.
6. Reporting Notes
Some labeled extraction standards in the sample analyses fell outside the control limits for ES
recovery, as denoted by the "Q" qualifier. The target analytes are quantified based on their ratio
to their labeled standard analogs.As a result, low or high labeled standard recovery do not
cause any change to ratios or contribute any additional error in the measurement of the target
analytes. The data have been accepted and reported with no further actions.
The results presented in this report are representative of the samples as provided to the
laboratory.
These analyses met the requirements of the TNI Standard.Any deviations from the
requirements of the reference method or TNI Standard have been stated above.
Enthalpy Analytical, LLC in Wilmington NC is accredited by the Louisiana Department of
Environmental Quality to the 2009 TNI Standard under certificate number 05075.

hwkood�l General Reporting Notes — Data Qualifiers
ENTHALPY
ANALYTICAL
The following are general reporting notes that are applicable to all Enthalpy Analytical,LLC -
Wilmington,NC data reports,unless specifically noted otherwise.
General Data Qualifiers
• B—The analyte was found in the method blank,at a concentration that was at least 10% of the
amount in the sample.
• Cxx—Two or more congeners co-elute. In EDDs, C denotes the lowest IUPAC congener in a co-
elution group and additional co-eluters for the group(`xx')are shown with the number of the
lowest IUPAC co-eluter.
• E—The reported concentration exceeds the calibration range(upper point of the calibration
curve). For FIRMS data,this condition does not imply additional measurement uncertainty. For
LC-MS/MS data,these values should be considered as having measurement uncertainty higher
than values within the calibration range.
• EDL—Estimated Detection Level: The EDL is unique to isotope dilution methods and reflects
the conditions of analysis at the time of analysis, including the equipment used. Where the MDL
is a static value,the EDL is a dynamic value.
• EMPC—Estimated Maximum Possible Concentration: EMPC is specific to Dioxin/Furan tests to
indicate the determined ion-abundance ratio was outside the allowed theoretical range(usually
due to being near the detection limit, although it can very rarely be caused by a co-eluting
interference). The EMPC concentration is adjusted to reflect the value at the theoretical ion-
abundance ratio.
• IR—The ion ratio between the primary and secondary ions was observed to be outside the
method criteria. The analyte concentration may be inaccurate due to interference.
• J—The analyte has a concentration below the minimum calibration level(LOQ value)but greater
than the LOD. These values should be considered as having measurement uncertainty higher than
values within the calibration range
• L-Indicates that an analyte has a concentration below the Minimum Detection Limit(MDL).
The reported concentration is not recommended for regulatory use as the analyte signal may have
a signal-to-noise ratio less than the criteria deemed necessary to be considered a detected analyte.
• LOD—Limit of Detection: For reports conforming to the DOD ELAP QSM,this is the QSM-
defined LOD. For reports conforming to TNI requirements(but not DOD ELAP QSM
requirements),this value is the minimum detection limit(MDL). The LOD is adjusted for sample
weight or volume.
• LOQ—Limit of Quantitation: For reports conforming to the DOD ELAP QSM,this is the QSM-
defined LOQ. For reports conforming to TNI requirements(but not DOD ELAP QSM
requirements),this value is the reporting limit(RL). The LOQ is adjusted for sample weight or
volume.

Tyson
Tyson Farms, Inc. of Wilkesboro (Tyson) and the Town of Wilkesboro (Town) have enjoyed a
mutually beneficial relationship that extends back the better part of seven decades, and Tyson
looks forward to extending that relationship into the future. Tyson is one of the largest poultry
production complexes within the Tyson Foods network, with a total production rate of
approximately 507,291,057 pounds per year. Tyson is also the largest employer in Wilkes
County, employing more than 2,620 team members.
The Tyson Wilkesboro Complex is a network of facilities that includes the processing plant,
which is capable of processing 2,000,000 birds per week, and a Food Service Plant, which
produces primarily fully cooked products for restaurant and institutional customers. Along with
these two facilities, the Fresh Plant produces a variety of products ranging from chill pack and
club stores to distribution to the fast-food industry in a 330,000 sq.ft. processing facility. With
many processes within our organization, water is a vital part of our process to ensure that we
meet the United States Department of Agriculture (USDA) standards.
Presently, some of the above facilities are operating below their capable production rate, and it is
a goal of Tyson to fully utilize the investments made at the Wilkesboro Complex. In conjunction
with the planned expansion and upgrade of the Wilkesboro Cub Creek WWTP, we are
requesting an increase in our existing Industrial User Permitted flow of 0.5 MGD, which would
bring our total permitted weekly average flow to 3.5 MGD. This increase will provide Tyson
with greater flexibility in meeting future production goals for the Wilkesboro Complex for the
next 15-year period.
We appreciate your consideration of this request. For reference, Part 1 Section F (General
Conditions) of our existing permit is attached. If you have any questions or require any
additional information, please contact me at (336)-651-3836.

Addendum #1
The Town of Wilkesboro Treatment Plant Expansion
Engineering Alternatives Analysis (EAA)
Dear Mr. Nick Coco:
HDR, in response to your November 9, 2022, email, has written the attached addendum to the
Town of Wilkesboro Engineering Alternatives Analysis (EAA) originally dated January 20, 2022.
HDR was asked to provide an estimate of the land application equipment costs as well as
provide the final cost of the land acreage and equipment to demonstrate why the land
application alternative was not the most economically feasible option.
For additional questions, please contact me at [phone].

Addendum #1 Further Support of Land Application Costs
Land application of wastewater is regulated pursuant to 02T .0500 by the Nondischarge Unit in
the NC Department of Water Resources (DWR).
A cursory evaluation of the land costs to implement a nondischarge land application system was
prepared based on existing nondischarge facilities (see Table A.1). The closest substantial
facility to Wilkesboro that land applies to similar soils in the project area is the Weyerhaeuser
facility in Surry County. The Weyerhaeuser land application rates and ratio of usable to
unusable area was used to determine the amount of overall land needed to be purchased by
Wilkesboro for a land application alternative. Weyerhaeuser loading rates associated with older
fields that may have been damaged by past land management practices (those listed as 20
in/yr) were not considered in estimating a loading rate for Wilkesboro. A loading rate of 31.8
in/yr was used for Wilkesboro based on Fields A, B, CN, and CS.
Table A.1 Weyerhaeuser Land Application Loading Rates

Rate
Field Soil (in/yr)
1 Braddock-Fairview Complex 20
2 Braddock-Fairview Complex 20

5 Braddock-Fairview Complex 20

8 Braddock-Fairview Complex 20
A Braddock-Fairview Complex 31.8
B Braddock-Fairview Complex 31.8
CN Braddock-Fairview Complex 31.8
CS Braddock-Fairview Complex 31.8
These are also consistent with other, smaller land application systems in the piedmont of North
Carolina. Attached are land application sites and limits from permits for Wayne Farms, LLC
(WQ0009826), Venture Properties, LLC (WQ0029195), and Kotis Properties, Inc.
(WQ0013808), which are all smaller facilities. All the soils for these permits are soils from the
piedmont/ upper piedmont. Loading rates in these permits vary between 12 to 52 inches per
year. While a few fields are rated higher in these permits than 31.8 inches per year, many are
also permitted for a lower rate. For a general evaluation of this alternative, a loading of
approximately 30 inches per year seems reasonable.
The only known municipal land application system in North Carolina that is of similar size is the
City of Jacksonville which is permitted for 9 mgd. This system has much higher loading rates
(average rate is slightly over 50 inches per year) than is possible for Wilkesboro due to soil
characteristics in the respective areas. Jacksonville has 2,331.67 of active spray area (total land
including buffers and unusable land would be much higher).
2

To determine the needed acreage Wilkesboro would need to purchase to obtain an effective
irrigatable 3,800 acres, a polygon was created around the spray fields associated with the
Weyerhaeuser permit. Even though this probably does not reflect the nature of putting together
thousands of acres across multiple parcels of land, it provides the necessary multiplier for
screening purposes to see if further analysis is needed. That is, it is likely Wilkesboro would
require multiple sites that would increase unusable areas versus the single site at
Weyerhaeuser. The polygon around the Weyerhaeuser site is approximately 70 acres. Given
the loading rates and accounting for unusable acreage, it is estimated Wilkesboro would need
more than 10,700 acres. A sample of land costs for larger parcels in Wilkes County was
approximately $6,200 per acre. This likely under values land as there are not many large
parcels near Wilkesboro and the town would need to buy smaller parcels with structures that
would dictate a higher price. Nonetheless, this would put the entire land application costs of the
entire 8 mgd facility to approximately $147 million (see Table A.2).
The cost estimate prepared for this analysis considers:
• treatment plant upgrade costs
• wet weather storage
• pumping to the land application sites
• irrigation equipment.

As most of the treatment facilities would still need to be constructed to meet 02T .0505(b) for
effluent limits, the land application alternative would likely be at least double that of a discharge
alternative. Treatment facilities would be needed since the existing facilities have reached the
end of their respective useful life.

FINDING OF NO SIGNIFICANT IMPACT
Article I, Chapter 113A of the North Carolina General Statutes requires an action to be subject to
the requirements of the North Carolina Environmental Policy Act(NCEPA) if it involves the
expenditure of public funds and if a potential impact is anticipated to the environment. The
project has been evaluated for compliance with the NCEPA and is determined to be a major
agency action, which will affect the environment.
Project Applicant: Town of Wilkesboro,North Carolina
Project Description: The proposed project will upgrade major components and
increase the capacity of the existing Wilkesboro Cub Creek
Wastewater Treatment Plant from 4.9 million gallons per day
(MGD) maximum month flow to 8 MGD maximum month flow.
Improvements will include upgraded influent pump station,
upgraded headworks, conversion of aeration basin to equalization
basin, influent buffering, addition of secondary treatment, tertiary
disk filtration, new UV disinfection system, new effluent flow
metering, improved aerobic digestion and thickening, replacement
of sludge dewatering unit, and a new operations building.
Project Number: CS370829-02 & SRP-W-0208
Project Cost: $72,000,000
Clean Water State $42,000,000
Revolving Loan Fund:
Wastewater State Reserve $18,000,000
Program:
Local Funds: $12,000,000
The review process indicated that significant adverse environmental impacts should not occur if
mitigative measures are implemented, and an environmental impact statement will not be
required. The decision was based on information in the Engineering Report/Environmental
Information Document (ER/EID) submitted by the applicant and reviews by governmental
agencies. The attached Environmental Assessment(EA),prepared by the Division based on the
ER/EID, supports this action and outlines mitigative measures that must be followed. This
Finding of No Significant Impact(FONSI) completes the environmental review record,which is
available for inspection at the State Clearinghouse.
No administrative action will be taken on the proposed project for at least 30 days after
notification that the FONSI has been published in the North Carolina Environmental Bulletin.

ENVIRONMENTAL ASSESSMENT
A. Proposed Facilities and Actions
The proposed project will upgrade major components and increase the capacity of the existing
Wilkesboro Cub Creek Wastewater Treatment Plant (WWTP) from 4.9 million gallons per day
(MGD)maximum month flow to 8 MGD maximum month flow. Improvements will include the
following components:
• Upgrade the influent pump station to increase the total pumping capacity of the municipal
flow.
• Retrofitted and upgrade the existing headworks including new screens and new grit
classifier.
• Convert the existing aeration basin to a wet weather flow equalization basin.
• Convert secondary clarifier 4 to an influent buffer tank to converge the municipal and
industrial flows upstream of secondary treatment and install pumps to convey the flow to
the biological treatment system.
• Upgrade secondary treatment by constructing three AquaNereda aerobic granular sludge
(AGS)tanks and converting secondary clarifier 3 to a dual sludge buffer(SB) and water
level correction(WLC) tank, which will serve to thicken the WAS before pumping to the
aerobic digesters; existing secondary clarifier 1 and 2,which are located in the
floodplain,will be decommissioned.
• A set of two tertiary disc filter may be installed as needed based on future nutrient
removal limits in the High Rock Lake basin.
• The existing UV system in the floodplain will be decommissioned, and a new UV
disinfection system will be installed outside of the floodplain.
• The existing effluent Parshall flume in the floodplain will be decommissioned, and a new
Parshall Flume will be constructed just downstream of the new UV disinfection system.
• The existing aerobic digesters will remain operational, and new disc thickening units will
be installed in 10 years or approximately by 2032. The timing of the disc thickening unit
is dependent on expected growth in the area and on the expenses of landfill tipping fees.
• The existing Huber Q-Press 800 sludge dewatering unit is nearing the end of its service
life and will be replaced with another unit of the same model. A second unit will be
installed to increase capacity.
• A new operations building will be constructed outside of the floodplain and near the
secondary treatment process for the plant operations staff.
Funding Status: The estimated total cost for the project is $72,000,000. The Town is applying for
a Clean Water State Revolving Fund(CWSRF) loan of$42,000,000 including $1,000,000 of
principal forgiveness and has been awarded a State Reserve Program (SRP) grant of
$18,000,000. The Town will fund the remainder of the project, including closing
costs/administrative fees of$1,110,0000,through local funds. The City may apply for additional
CWSRF funding.

B. Existiniz Environment
Topography and Soils. Wilkesboro is located in the Piedmont physiographic province. The
elevation of the project area ranges from 946 feet mean sea level (msl) to 1,038 feet msl.
Portions of the project site are located within the 100-year flood plain.
The project site includes the following soil units: Banister fine sandy loam, 1 to 6 percent slopes,
rarely flooded(BaB), moderately well drained or somewhat poorly drained soils; characterized
as strongly acidic; Codorus loam, 0 to 2 percent slopes, frequently flooded (CoA), consist of very
deep, moderately well drained and somewhat poorly drained soils; Dan River loam, 0 to 4
percent slopes, occasionally flooded(DaA)very deep, well drained soils, characterized as very
strongly acidic in the upper parts through slightly acidic in the lower parts; Danripple sandy clay
loam, 8 to 15 percent slopes, moderately eroded(DpC2), very deep, well drained soils,
characterized as very strongly acidic to moderately acidic; Fairview sandy loam, 15 to 25 percent
slopes (FaD), very deep,well drained soils, characterized as extremely acidic to moderately
acidic throughout; Fairview sandy clay loam, 8 to 15 percent slopes, moderately eroded(FcC2)
soils, similar to Fairview sandy loam located in less steep terrain; Fairview-Urban land complex,
2 to 15 percent slopes (FrC) soils, also similar to Fairview sandy loam typically including built
upon urban lands; and Rhodhiss fine sandy loam, 25 to 60 percent slope (RdE), very deep, well-
drained soil characterized by very strongly acidic to slight acidic throughout.
Surface Water. The project area is located in the Yadkin Headwaters Subbasin of the Yadkin-
Pee-Dee River Basin(HUC 0304010103). Surface waters in the area include Cub Creek, Little
Cub Creek, and the Yadkin River. All are rated Class C. Cub Creek is impaired for poor fish
community.
Water Soply. The Town's public water supply draws water from the Yadkin River.
C. Existing Wastewater Treatment Facilities
The Town owns and operates the Club Creek WWTP, which is an activated sludge plant with a
permitted capacity of 4.9 MGD under NPDES Permit Number NC0021717 discharging to the
Yadkin River. The WWTP was constructed in 1965 with various improvements made since
construction. The plant has been maintained in good condition overall but is nearing capacity.
Some service components are nearing the end of their useful life. The liquids train consists of an
influent pumping station, screening and grit removal, an aeration basin with surface mixers,
secondary clarification, and UV disinfection. The solids train consists of aerobic digestion,
dewatering by a Huber screw press, and landfilling of dewatered solids. The average daily
effluent flows in 2019 and 2020 were 4.44 MGD and 4.77 MGD, respectively. The WWTP
receives 70 to 80 percent of its flow from Tyson Foods, Inc., and the WWTP site contains
Tyson's influent pump station and two of Tyson's pretreatment basins. The 2021 current average
daily flow is 4.21 MGD, which is approximately 86% of the plant's permitted capacity. The
Town has received 22 Notices of Violations (NOVs) for effluent permit exceedances between
December 2016 and December 2021. Several components are located within the 100-year
floodplain.
2

In addition to the WWTP, the Town owns and operates a wastewater collection system
consisting of 67 miles of gravity sewer, 1,383 manholes, 10 miles of force main, and 13 pump
stations. An asset inventory and assessment study was recently completed including a 10-year
rehabilitation and replacement plan for the collection system.
D. Need for Proposed Facilities and Actions
The Town's existing WWTP is aging and under capacity. Upgrades are needed to replace aging
equipment, improve treatment, and provide additional capacity for anticipated demand. The
Town's NPDES Permit previously included requirements to monitor nutrients but did not specify
numerical nutrient limits. The speculative permit includes numerical limits for both TN and TP
which will require improved treatment, and the Town is experiencing industrial and commercial
growth.Nutrient limits to the Yadkin River may change depending on the final nutrient strategy
developed for High Rock Lake. The Town has received 22 Notices of Violations (NOVs) for
effluent permit exceedances between December 2016 and December 2021. In July 2021, the
Town received a Sewer Line Moratorium from NCDEQ. The moratorium was issued because in
the previous calendar year when the Town's effluent from the WWTP flow averaged 4.8 MGD
representing 97.2 percent of the plant's current treatment capacity.
The purpose of this proposed project there is to provide an upgraded and expanded facility that
will enable Wilkesboro to meet future permit limits while accommodating future growth.
E. Alternatives Analysis
No-Action: The No-action alternative would continue operation of the WWTP with aging
equipment, components located in the floodplain, exceeding flow limits, and unable to meet
future effluent water quality standards for total nitrogen and phosphorus. This alternative is
infeasible and was rejected.
Alternative 1 —AquaNereda Aerobic Granular Sludge (AGS) (Preferred): This alternative
consists of upgrading the secondary treatment process using an AquaNereda aerobic granular
sludge (AGS) system operating in three new sequencing batch reactors and increasing the
capacity of the WWTP from 4.9 MGD to 8 MGD. Associated improvements to the plant include
influent pump station upgrades, the existing headworks will be retrofitted and upgraded,
conversion of existing Clarifier No. 4 to an AGS influent buffer tank, construction of new tanks
required for the Nereda process, construction of a new UV disinfection system and effluent
measurement/monitoring facilities, and the addition of a new solids dewatering screw press. A
new operations building is also included in this alternative. The existing aerobic digesters will
remain in-use. This alternative is preferred because it meets the desired treatment flows for the
plant with the lowest treatment cost per gallon, greatest energy savings, and smallest spatial
footprint compared to other alternatives.
Alternative 2—Oxidation Ditch with Mobile Organic Biofilm Process: This alternative would
also upgrade treatment and increase the plant capacity using an oxidation ditch with Mobile
Organic Biofilm(MOB)process by Nuvoda. The oxidation ditch would be filled with Kenaf
3

media to enhance treatment and settling, and a media retention screen would be included to filter
out any wasted media and return it to the biological process. Associated plant upgrades would
include updates to the influent pump station,rehabilitation of existing headworks system,
construction of a new ultraviolet(UV) disinfection system, construction of a high river effluent
pump station, addition of a new effluent flow meter,upgrades to the existing RAS pump station,
and addition of a new solids dewatering unit. This alternative was rejected due to higher
treatment cost per gallon, higher energy demand, and larger spatial footprint compared to the
preferred alternative. Additionally,this alternative would include constructing new treatment
components within the floodplain.
Alternative 3 —Conventional Sequencing Batch Reactor(SBR): This alternative consists of a
conventional SBR system with four tanks located adjacent to the existing maintenance building.
Associated plant improvements would include upgrades to the influent pump station,
construction of new headworks north of Tyson's pretreatment basins, construction of a new UV
disinfection system, addition of a new effluent flow meter, and addition of new solids thickening
and dewatering units. A new plant operations/control building would also be included in this
alternative. This alternative was rejected due to higher treatment cost per gallon, higher energy
demand, and larger spatial footprint compared to the preferred alternative.
F. Environmental Consequences and Mitigative Measures
Topography and Soils: Significant impacts to topography and soils are not anticipated. The
WWPT site has already been disturbed. Minimal grading will be required. Total impervious area
will change from 14 percent to 17 percent. Disturbed areas that are not within building footprints
will be re-seeded after construction. Impacts to the floodplain will include removing and
demolishing the existing aeration basin and Tyson influent pump station, adding rock to existing
access roads, and temporary erosion control devices. There will be no permanent changes to
existing elevations within the 100-yea floodplain. The project will comply with local FEMA
regulations including appropriate permits. The project will expand the WWTP, and secondary
and cumulative impacts (SCI) are possible due to future wastewater lines and development in the
service area. These impacts will be minimized through adherence to Town of Wilkesboro and
Wilkes County ordinances addressing floodplain development, flood damage prevention, sewer
use, and watershed development.
Land Use: Significant impacts to land use are not anticipated. The project is located within sites
owned by the Town of Wilkesboro and Tyson Foods and used for wastewater treatment. SCI will
be managed through the Town's Comprehensive Land Use Plan, which includes provisions for
preserving open spaces.
Wetlands: Significant impacts to wetlands are not anticipated. There are no wetlands on the
project site and therefore no direct impacts anticipated. SCI related to future growth will be
minimized through the Wilkes County Watershed Ordinance, which limits certain development
and places impervious surface limits on certain developments to project wetlands and streams.
Important Farmlands: Significant impacts to important farmlands are not anticipated. The project
area does include soils designated as prime and unique farmland, but the site is already disturbed
4

and not in agricultural use. Potential SCI will be minimized through the NC Agricultural
Development and Farmland Preservation Fund, which promotes farmland preservation.
Public Lands and Scenic, Recreational, and State Natural Areas: Significant impacts to public
lands, scenic, recreational, or state natural areas are not expected. Parks and public lands in the
surrounding area may experience increase in noise during construction activities,but these
impacts will be minor and temporary.
Cultural Resources: Direct impacts to cultural and historic resources are not anticipated. The
Downtown Wilkesboro Historic District is located within a mile of the project area,but impacts
are not anticipated. Five previously recorded archaeological sites are located within one mile of
the project site and are not expected to be impacted due to construction activities occurring at
previously disturbed locations. The North Carolina State Historic Preservation Office (SHPO)
conducted a review of the project and is aware of no historic resources which will be impacted
by the project(July 29, 2022, ER 21-2531). Potential SCI will be minimized through
Wilkesboro's Historic Preservation Committee's guidelines.
Air Quality: No significant impacts to air quality are anticipated. Construction activities may
cause a temporary increase in emissions and will cease when construction is complete. Dust
control measures will be implemented, and open burning of materials will not be allowed.
Testing of emergency generators may cause temporary, short-term emissions. Otherwise, the
project will not result in new sources of air pollution. SCI to air quality are not anticipated.
Noise Levels: No significant noise impacts are anticipated. Noise from construction activities
will be temporary with construction hours restricted under the Town's Noise Ordinance.
Operational noise impacts may increase slightly as a result of additional components and new
technologies at the WWTP. Forested areas surrounding the project site create natural noise
buffers to minimize any noise for surrounding residences. SCI may include construction noise
for wastewater line installation and residential and industrial development. These impacts will be
minimized through compliance with Wilkes County's High Impact Land Use Ordinance.
Water Resources: No significant negative impacts to water resources are anticipated. A
sedimentation and erosion control plan will be implemented to minimize impacts to surface
water from construction activities. The project will provide a benefit to nearby surface waters by
removing several components from the floodplain and improving the treatment process and
qualify of effluent from the WWTP. SCI related to future develop will be minimized through the
Wilkes County Watershed Ordinance and stormwater provisions in the Town's Subdivision
Ordinance.
Forest Resources: Significant impacts to forest resources are not expected. The project site
includes scattered wooded areas. A small area of approximately 0.18 acre of upland forest will
be cleared. SCI from future development will be minimized through the Town's Tree,
Subdivision, and Zoning ordinance and Wilkes County Watershed Ordinance.
Shellfish or Fish and Their Habitats: Impacts to shellfish, fish, and their habitats are not expected
to be significant. There are no known occurrences of threatened or endangered aquatic species in
5

the project site or immediate surrounding area. Impacts to aquatic species from construction
activities will be minimized through adherence to a sediment and erosion control plan. Aquatic
species will benefit from improved wastewater effluent quality. SCI related to future develop
will be minimized through the Wilkes County Watershed Ordinance and stormwater provisions
in the Town's Subdivision Ordinance.
Wildlife and Natural Vegetation: No significant impacts to wildlife and natural vegetation are
expected. No threatened or endangered species have been identified within one mile of the
project site. Suitable habitat exists for the Northern long-eared bat and tricolored bat. To protect
these species, the recommendation from the U.S. Fish& Wildlife Service (USFWS)to avoid tree
removal between March 15th and November 15t1i will be followed. Impacts to other terrestrial
species are not anticipated. Most of the project is located in previously disturbed and maintained
areas. SCI related to future development will be minimized through County and Town
development ordinances.
Introduction of Toxic Substances: The project is not expected to introduce toxic substances into
the environment. Construction specifications will include provisions for fuel, oil, and lubricants
to be contained and equipment to be properly maintained to prevent leakage and spills.
Chemicals used on-site will be controlled and maintained as currently required at the WWTP.
The U.S. Fish and Wildlife Service was consulted and provided guidance (June 2, 2023). The
North Carolina Wildlife Resources Commission,Natural Heritage Program, and DWR Winston-
Salem Regional Office do not object to the proposed project. The U.S. Army Corps of Engineers
was consulted and did not object to the project. The North Carolina Department of Natural and
Cultural Resources is aware of no historic resources which will be impacted by the proposed
project(July 29, 2022, ER 21-2531).
G. Public Participation, Sources Consulted
The Town of Wilkesboro held a public meeting on November 6, 2023. The meeting included a
presentation about the proposed project and opportunity for public comments. The Town also
provided a 30-day period for submission of written comments. Comments at the meeting
included support for the project from a councilman and a question about publishing time. No
written comments were received.
The current user charge for a typical residential customer is $30.77 per month for sewer and
water combined,based on consumption of 5,000 gallons per month. The proposed project will
increase the bill by $9.62, for a future sewer bill of$40.39. The Town intends to raise rates
through a series of smaller annual increases.
