Re: NC0021717 Cub Creek WWTP Renewal and Expansion
Additional Information Request
Town of Wilkesboro, NC
Dear Mr. Coco,
We are writing in response to your request for additional information for the Renewal Application
and Expansion Request for the Town of Wilkesboro's Cub Creek WWTP(NC0021717). A new copy
of the Renewal Application has been filled out, per your recommendation, using the latest version of
EPA Form 2A. Subsequent digital attachments have also been included. The Renewal Application
for NC0021717 Cub Creek WWTP is attached to this letter. This letter and subsequent attachments
have been uploaded to Microsoft Teams.
Additionally, HDR has reassessed the population projections and flow projections for the WWTP
Expansion Request. Below, we have prepared a response to each of your comments on the
Expansion Request included in your email dated July 21, 2022.
Flow Justification
Comment: Please provide additional justification for expansion to 9MGD. The existing modification
request does not clearly demonstrate at this point a need for a 9 MGD capacity in addition to the
current expanded flow tier in the existing permit. Does the Town know what the industrial demand is
projected to be out to 2060, or have any other clear contracts or commitments from other sources of
wastewater flows?
Response: Per this request, the Town's service area population projections and industrial flows
were reassessed. As such, the proposed maximum month design flow has been revised to 8 MGD,
which is about a 62% increase in the permitted capacity. Below is a summary table indicating the
need for the Cub Creek WWTP to expand. In 2020, the effluent flow was about 95% of the
permitted capacity and thus, the Town was put under a Sewer Moratorium. Based on 20-year
projected flows and growth, the second-tier permit limit of 6.6 MGD would not be sufficient.
Considering annual average flows for recent years, the WWTP would be operating at nearly 70%
capacity at start-up with no consideration for future growth. Additionally, Tyson Foods, Inc. is
requesting an additional 0.5 MGD flow to be added to their existing 3 MGD permit and Wilkesboro

100 North Main Street,Suite 1500,Winston-Salem,NC 27101-4015
[phone]

desires to allocate 0.6 MGD for additional industrial allocation(which includes leachate), other than
Tyson. The total industrial growth would then be 1.1 MGD in 20 years.
Effluent% of Effluent% of
4.9 MGD 6.6 MGD
Parameter Effluent Permit
Capacity
2018 Annual Average Daily Flow(mgd) 4.1 84% 62%
2019 Annual Average Daily Flow(mgd) 4.4 90% 67%
2020 Annual Average Daily Flow(mgd) 4.7 95% 71%
2021 Annual Average Daily Flow(mgd)' 4.4 90% 67%
Updated population projections and corresponding effluent flow projections are included in
Attachment A. Additionally, a letter from Tyson Foods containing their expanded flow proposal has
been requested. Once received this letter will be included in Attachment B as an addendum.
Future Flow Projections
Comment: For Table 3.4[in the EAA], it appears that 4.9 MGD was used as a datum, and additional
capacity was added to that to estimate total flow. Am I understanding this correctly?
Response: This is correct. Based on the original formulation of Table 3.4, the permitted capacity of
the WWTP(4.9 MGD)was used as the datum. The goal of this method was to emulate the flow
projection tables from NC Division of Water Infrastructure's Engineering Report(ER) requirements.
To be more accurate an alternative method of flow projections was calculated,which is based on
per capita flow usage historically and by quantifying the current commercial and industrial users.
Inflow and Infiltration
Comment: Existing conditions at the plant, as described in Table 3.3[in the EAA], indicate that
Inflow and Infiltration (I&I) is a major contributor to flowrates experienced at the plant(roughly 1.5
MGD). Please provide a table that considers flow demand without incorporating l&l and provide a
cost estimation related to l&l resolution as part of the EAA analysis.
Response: The Town of Wilkesboro at present does not utilize collection system flow monitors to
accurately quantify infiltration and inflow in the system. It is known that there is an infiltration and
inflow within the system, and it is a top priority of the Town to address infrastructure in the collection
system that is subject to I/I. The Town has already begun this process by conducting a preliminary
analysis of the collection system (WK Dickson, 2018).
The information in Table 3.3 was refined to represent the Town's collection system I/I more
accurately, but on average, the infiltration is approximately 1 MGD. The following changes were
made that yielded a slight decrease in l&l.

1. The population data in Table 3.3 were updated with the certified population data (2020) by
the State of North Carolina.
2. Additionally,the residential per capita flow as increased from 70 gpcd to 100 gpcd to follow
Ten State Standard's recommended residential flow.
3. Rather than using NC DEQ's standard commercial flow per capita value of 15 gpcd, the
number of commercial institutions were quantified alongside their projected wastewater
generated. This more accurately quantified commercial flow contributions.
Comment: It appears, based on this analysis, that potentially controlling present l&I issues could
provide the Town sufficient capacity to meet future demand projections while maintaining the
NPDES permit's existing 6.6 MGD flow tier.
Response:As previously noted, when considering the 20-year projected flows and growth,the
second-tier permit limit of 6.6 MGD would not be sufficient. Considering annual average flows for
recent years, the WWTP would be operating at nearly 70% capacity at start-up with no
consideration for future growth. In August 2021, the Town received a Wastewater System Asset
Inventory and Condition Assessment for the collection system. This report was prepared by WK
Dickson &Co., Inc. and is included in Appendix 1 of the ER/EID. The result of this evaluation
indicated that in the next 10 years, the Town's annual project costs for gravity sewer collection
system replacement would average$1,129,000 per year and $625,000 on average for
rehabilitation.
Please contact me if you have any questions or need additional information.
