Section 1
General Information
1.1 Project Identification
Henderson County (the County) proposes to construct a new sanitary sewer collection system,
composed of both gravity and pumped systems to serve existing residential and commercial
properties in the unincorporated community of Edneyville, North Carolina. Sanitary sewer
management in this portion of the county is currently composed of private septic systems and
three wastewater treatment plants (WWTPs). An overall map of the proposed collection system
improvements is provided in Figure 1.
To treat the sanitary sewage collected by this new collection system, the County is proposing to
construct, own, and operate a new W WTP. The new W WTP will be constructed on an
approximately 15-acre greenfield parcel (parcels to be further subdivided pending discussions
with property owner) at the confluence of Clear Creek and Laurel Branch. The W WTP site
footprint will be approximately 0.5 acres. The W WTP will be a "package" -type plant and have the
..
capacity to treat 0.2 million gallons per day (MGD) maximum month flow (MMF). It is
conceptually planned to allow for future capacity expansions up to 0.5 MGD via installation of
additional packaged treatment units. A National Pollutant Discharge Elimination System (NPDES)
A%
permit is therefore requested for the discharge of treated wastewater Flow to Clear Creek.
.�
The W WTP will include an influent pump station and screening, a flow equalization cell, two
conventional activated sludge treatment trains, two secondary clarifiers, a sludge holding tank,
and effluent disinfection via chlorine. No supporting administration or laboratory facilities are
included as part of the initial plant construction, but they may be considered for future
Aft
expansions. Final design of the facility will confirm the conceptual treatment process
configuration identified above. Sizing and location of influent pumping will also be confirmed
based on the final profile for the gravity sewer collection system.

Section 1 • General Information
The information in Table 1 is provided as the Basic Identification of the Project as required in the
North Carolina Division of Environmental Quality (NCDEQ) NPDES UniVs Engineering Alternatives
Analysis (EAA) Guidance Document (October 2019). A facility address is not provided, as the
parcels have no assigned address at this time; a County parcel identification number (PIN) is
provided in lieu of an address.
Table 1. Project Identification
1.2 Discharge Criteria
One discharge location was examined in this alternative analysis: Clear Creek. According to the
EAA Guidance Document, potential restrictions for a wastewater discharge to Clear Creek have
been examined.
1.2.1 Zero -Flow Streams
The State of North Carolina places restrictions on the discharge of oxygen -consuming waste in
streams designated as zero flow. The U.S. Geological Survey (USGS) South Atlantic Water Science
in Raleigh, North Carolina was contacted for assistance in determining the low -flow
characteristics for Clear Creek. Low -flow estimates were provided for Clear Creels.
Correspondence with USGS has been provided as Appendix A.
Neither gauged streamflow data nor a previous low -flow determination was available for Clear
Creek. USGS provided provisional estimates based on characteristics of the stream and an
examination of available literature (statewide and basin -specific reports). USGS estimated the
7Q10, 30Q2, W7Q10, and 7Q2 low -flow characteristics as presented in Table 2.

Section 1 • General Information
In accordance with the data presented in Table 2, USGS stated that the average annual discharge
ranges from 40.9 to 81.8 cfs with an average of approximately 58 cfs and median of 51.2 cfs.
Based on the information presented, Clear Creek is not subject to zero -flow stream restrictions.
The information provided is based on a preliminary assessment and is subject to revision pending
collection of future data and further analyses by USGS.
1.2.2 Stream Classifications
Clear Creek is classified as a Class C surface water by the NCDEQ. The restrictions for Class C
surface waters are defined in 15A North Carolina Administrative Code 02B .0211 and include
limits for total chlorine residual, dissolved oxygen, settleable solids, metals, pH, and turbidity,
among others. Waters must remain suitable for aquatic life propagation and maintenance of
biological integrity, wildlife, secondary recreation, and agriculture. It is not anticipated that the
treated Flows discharged from the proposed W WTP will violate the Class C water quality
standard. It is assumed that receiving stream classification restrictions do not preclude the
proposed discharge into Clear Creek.
1.2.3 Basinwide Water Quality Plan
Clear Creek is a part of the Upper French Broad subbasin (Hydrologic Unit Code [HUC)
06010105) of the French Broad River Basin. According to the 2011 French Broad Basinwide
Water Quality Plan (Plan), portions of Clear Creek are listed as Impaired, with other portions
listed as Supporting. The section of Clear Creek near the proposed discharge location is within the
Clear Creek Subwatershed (HUC 060101050302), itself within the Mud Creek Watershed (HUC
0601010503) and has been assigned the assessment unit (AU) number 6-55-11-(S). The
proposed discharge point is at the confluence of Clear Creek and Laurel Branch. The segment of
Clear Creek from Lewis Creels to Laurel Branch (AU 6-55-11-(5)a) is listed as Impaired for
biological integrity because of a Fair bioclassification at a benthic macroinvertebrate sampling
site. The Plan (pg. 9) states that "potential causes include pesticides from apple orchards and
overall habitat degradation," but that further study of the subwatershed is needed. No
information is provided on the segment of Clear Creek from Laurel Branch to Mud Creek (AU 6-
55-11-(5)b). According to the Plan, there are 17 minor and 1 major NPDES individual wastewater
discharge permits within the Mud Creek Watershed (these numbers may have changed in the
intervening years).
The Plan does not preclude the proposed discharge.
1.2.4 Impaired Waters and/or Total Maximum Daily Load Restrictions
In the 2022 North Carolina Integrated Report (303(d) list), Clear Creek (Aus 6-55-11-(5)a and -
(S)b) was given an Assessment Criteria status of "Exceeding Criteria' for benthos. Clear Creek is
not subject to any total maximum daily load (TMDL) restrictions (except the statewide mercury
TMDL) as of August 2022, according to the NCDEQ Modeling and Assessment Branch website.
1.2.5 Presence of Endangered Species
C1earWater Environmental Consultants (ClearWater) is preparing the Environmental Assessment
(EA) for both the proposed WWTP location and the upstream proposed collection system
conveyance improvements. The EA has been submitted and the State Environmental Review
Clearinghouse has provided comments. C1earWater is currently working to address these
comments and submit the finalize EA. The full report will be made available upon completion, if
requested. The following information has been provided in coordination with the EA report.
t-a Smith

Section 1 • General Information
C1earWater obtained an official protected species list through the U.S. Fish and Wildlife Service
(USFWS) Information for Planning and Consultation and North Carolina Natural Heritage
Program (NHP) databases on April 13, 2022. These lists provide existing data concerning the
presence or potential occurrence of threatened or endangered species in the defined project
boundary. The USFWS lists seven federally threatened and endangered species, in addition to the
bog turtle (threatened because of similar appearance) and bald eagle, as occurring or potentially
occurring in the project boundary. The NHP lists two species. The federal and state protected
species potentially occurring within the project boundary are presented in Table 3.

2045
Edneyville is primarily a rural and agricultural community with scattered suburban
developments. Currently, most of the community is unsewered and relies on septic treatment
systems for wastewater handling and disposal. There is limited data on current wastewater flows
within the entire sewer subbasin that would contribute to the new WWTP. There are also three
existing package WWTPs within the service area for the Blacksmith Run subdivision (NPDES
Permit NC0088056), Western North Carolina Justice Academy (NPDES Permit NC0086070), and
Camp Judea (NPDES Permit NC0033430— this discharge is seasonal). The new sanitary sewer
system and WWTP would allow these plants to be abandoned and their permits discontinued.

Section 2 • Population and Flow Projections
WGLA Engineering, PLLC (WGLA) developed the Edneyville Sewer Study Update Memorandum,
which established initial expected contributors and sanitary sewer flows for a new Edneyville
sewer collection system. According to discussions between WGLA and the County, the list of likely
and possible initial users and their respective estimated sanitary sewer flows have been refined
and are detailed below in Table 4. All other likely and possible users currently operate on private
septic systems.

2.2.2 Flow Projections and Peaking Factors
Based on the likely and possible contributors listed above in Table 4, the new Edneyville sewer
collection system is anticipated to collect up to 65,000 gpd upon initial activation. According to
discussions between WGLA Engineering and Henderson County, the anticipated growth rate for
this system is expected to be approximately 2.54 percent (%) per year, comparable to that of the
Cane Creek collection system in northern Henderson County. This initial flow and growth rate
were used by CDM Smith as the basis to develop flow projections and peaking factors for the
Edneyville sewer collection system and package WWTP.
Because of the lack of historical flow data for each contributor listed in Table 4, CDM Smith
established Minimum Day, Average Day Maximum Month, and Maximum Day peaking factors for
the Edneyville sewer collection system in accordance with the Water Environment Federation's
Design of Water Resource Recovery Facilities, Manual of Practice 8, Sixth Edition, that has
2-2 Smith

Section 2 • Population and Flow Projections
established peaking factor relationships based on average daily Flows for typical separated sewer
collection systems. Peaking factor for Peak Hourly Flow was based on North Carolina Department
of Environment and Natural Resources Minimum Design Criteria for the Permitting of Pump
Stations and Force Mains, which requires a minimum peaking factor of 2.50 for Peak Hourly Flow.
In addition to the likely and possible users, Henderson County suggested allocating
n►
approximately 50,000 gpd on an Average Day Maximum Month basis, for future industrial
development (assumed to be primarily domestic waste contributors). CDM Smith adjusted this
allocation to Average Daily Flow, Minimum Day, and Maximum Day according to the established
peaking factors. Flow projections and peaking factors for the Edneyville sewer collection system
„y
are detailed below in Table S. The schedule for construction of the new collection system is not
well defined and growth in the area pre -regional sanitary sewer service is expected to be limited.
'^
Therefore, the 65,000 gpd estimated in Table 4 is estimated to be accurate for Year 1 of the
collection system operation.
�►
Completed analysis assumes a 20-year life for the facilities. Based on discussions with NCDEQ, the
WWTP should be designed for the Average Day Maximum Month condition, which would be
equivalent to nominally 200,000 gpd in Year 20 of operation.

Disposal Alternatives
The NCDEQ NPDES Unit's EAA Guidance Document requires new NPDES permit applicants to
evaluate alternative disposal methods. The following alternatives must be considered:
■ Connecting to existing WWTP
■ Land -based disposal
■ Wastewater reuse
■ Surface water discharge
■ Disposal combinations
Each alternative is discussed herein. As the upstream sewer collection system is common to all
options (Figure 1 and discussion in Section 2), these estimated costs have been excluded from the
evaluation and discussion below.
3.1 Connecting to Existing WWTP
3.1.1 Existing Sewer Systems and WWTPs
The City of Hendersonville (City) owns and operates the only collection system within a 5-mile
radius of the proposed WWTP. The three package plants previously mentioned will be taken
offline in all alternatives and are not considered herein. The facilities they service will be
connected to the proposed collection system. The City collects and conveys sewage to the
Hendersonville Wastewater Treatment Plant (WWTP). The Hendersonville WWTP (NPDES
Permit NC0025534) is permitted for 4.8 MGD and discharges to Mud Creek, a Class C surface
water.
The City has indicated that the Hendersonville WWTP can accept the anticipated flows from the
proposed sewer collection system (Appendix B). The City identified a potential connection point
to their collection system —an existing 24-inch sewer line near the confluence of Clear Creek and
Wolfpen Creek. Additional sewer and easement acquisition is required to connect the proposed
collection system to the existing one. Figure 3 shows the connection point and additional 24-inch
gravity sewer required for this option.
The present value of connection to an existing sewer for this waste stream, which considers the
additional collection system, associated operation and maintenance (0&M) costs, and a sewage
rate surcharge, is $12.3 million. The cost evaluation for this disposal alternative is included in
Appendix C. Based on discussions with the City of Hendersonville, the new County sewer
customers would pay the fees and rates for customers outside of City limits, which can be set up
to 60% above the rate for customers within City limits.

3.1.2 Planned Sewer System and WWTPs
^
Other sewer systems that could potentially accommodate the wastewater are not planned near
the proposed WWTP.
A+.
^
3.2 Land -Based Disposal
.%
The U. S. Department of Agriculture Natural Resources Conservation Service rates soil
^
characteristics on a 0.01 to 1.00 scale to represent limitations of the use of land -based application
of wastewater (0.01 being most applicable,1.00 being least applicable). Soils are then assigned a
rating class to indicate how favorable or unfavorable for use they are, considering their rated
^
characteristics. Properties considered include depth -to -water table, hydraulic conductivity,
,^
depth -to -bedrock, salinity, density, and erodibility, among others.
„y
The soils in 3,750 acres surrounding the proposed WWTP were evaluated to determine their
suitability for land -based application of wastewater. Soils rated as "very limited" were dominant
in the region, making up 96.6% of the evaluated area. This is a good indication that soils are
�'►
unfavorable for this application. An application rate of 1 inch per week was assumed for
,.�
calculations of required land.
Approximately 52 acres would be required to apply the maximum month treated wastewater
discharge of 0.20 MGD, based on the determined application rate. There is not sufficient land on
^'
the proposed plant site for land -based application. Recent property listings indicate that very
little land is available for sale in the area adjacent to the plant. Further, much of this land is
..,
located within the floodway or 100-year floodplain. Assuming sufficient available land is found
and based on the current local sale price of approximately $30,000 per acre (estimated from
^
current property listings), the cost to purchase the required land would be $1.6 million. CDM
^
Smith assumed that 1 mile of force main will be necessary to convey land application flows to a
...
suitable site.
..
There are several hundred acres of rural farm and agricultural land within 5 miles of the
^
proposed W WTP that may be suitable for land application of treated wastewater. Figure 4
identifies land classified as a Voluntary Agricultural District —defined as land set aside by
AM
landowners for agricultural use only —within the vicinity of the site. This map does not identify
.^
all nearby agricultural land because of limitations in the available data on zoning and land use.
^
The proximity of several potential end users for land application, even within a limited data set,
indicates that agricultural land application could be a viable alternative to surface water
discharge.
^
There are several limitations to relying solely on land application for disposal of treated
^
wastewater. Agricultural demand for irrigation water is both intermittent and seasonal. Wet
^
weather may temporarily reduce the demand for irrigation throughout the growing season, and
demand will decline once the growing season has passed. Sustained low temperatures may
Prohibit or prevent both traditional land application and agricultural application. Large volumes
^
of treated wastewater may therefore need to be stored to accommodate a fluctuating demand.
Additionally, specific crop water quality requirements for agricultural application must be
developed in coordination with any potential agricultural users in addition to the baseline
.►
treatment standards.

Section 3 • Disposal Alternatives
The present value of a County -owned land application system for this waste stream, which
considers the land acquisition, wastewater treatment facility, storage, distribution system, and
0&M costs, is $17.2 million. The present value for agricultural land application is $13.3 million.
The cost evaluation for land -based disposal is included in Appendix D.

Section 3 • Disposal Alternatives
Oak The large amount of agricultural land and its relative proximity to the proposed facility site could
make this a feasible disposal option. However, it would be best done in combination with another
Aft disposal alternative, because of the limitations discussed previously. If agricultural users are
uninterested in using all or part of the treated wastewater, traditional land application is cost -
prohibitive.
3.3 Wastewater Reuse
WGLA and CDM Smith worked with the County's Partnership for Economic Development (the
Partnership) to identify potential commercial and industrial users of reclaimed water within a S-
mile radius of the proposed W WTP. A total of 13 potential customers were identified, though the
Ask
Partnership noted that interest in reclaimed water usage at the facilities was unlikely. Figure 5
'►
presents the 13 identified potential users in relation to the treatment plant site. Because of the
distance of all industrial sites, a minimum length of 5 miles of force main is assumed necessary to
convey reuse flows to one or more users.
Wastewater reuse is subject to some of the same limitations as land application of wastewater.
While seasonal demand is less likely to be a factor, the demand for reclaimed water may only be
^"
intermittent, necessitating storage of a large volume of treated wastewater. Customers may also
..2%
have specialized water quality needs for their application, and these requirements may differ
from user to user, further complicating and adding cost for treatment.
The present value costs of reuse, which considers the wastewater treatment facility, storage,
distribution system, and 0&M costs, is $15.8 million. The cost evaluation for land -based disposal
is included in Appendix E.
The small potential customer base for reclaimed water, their distances from the treatment facility
site, and the increased capital cost render this alternative infeasible.
3.4 Surface Water Discharge
Disposal of the treated effluent into surface water is a viable disposal alternative that will be
regulated by a NPDES permit. The French Broad Basinwide Water Quality Plan identifies 17 minor
and 1 major NPDES individual wastewater discharge permits within the Mud Creek Watershed as
of 2011. The new sewer collection system will take three existing package treatment facilities
"^
with minor NPDES discharge permits offline by consolidating their flows and conveying them to
one treatment facility (discussion in Section 2.2). The proposed W WTP is expected to also have a
A6%
minor NPDES permit. Potential restrictions to wastewater discharge to surface waters as outlined
in EAA Guidance Document were presented in Section 1.2.

Section 3 • Disposal Alternatives
The proposed WWTP will have an initial capacity to treat 0.2 MGD MMF. The proposed WWTP
will be a package plant with a conventional activated sludge treatment process. It is conceptually
planned to allow for future capacity expansions up to 0.5 MGD via installation of additional
packaged treatment units. Anticipated processes include the following:
■ Influent pump station and screening (no grit removal)
■ Equalization cell
■ Two trains for conventional activated sludge treatment with aeration system and
blowers
■ Two secondary clarifier cells
■ One sludge holding cell
■ Effluent disinfection with chlorine and dechlorination
NCDEQ has provided speculative limits for the proposed facility discharge to Clear Creek at 0.2
MGD and the anticipated buildout flow of 0.5 MGD. Table 6 presents these speculative limits.

Treated effluent will be conveyed by gravity to the proposed discharge location on Clear Creek,
which will consist of an outlet with protective riprap. A flow metering device will be located
upstream of the discharge location. Appropriate treatment will be provided to neutralize any
remaining chlorine residual to meet permitting standards. Figure 7 provides a proposed outfall
location and site plan. The sludge holding tank will be periodically emptied and sludge disposed
of at a landfill.
The present value of surface water discharge for this waste stream, which considers land
acquisition, the treatment plant, and 0&M costs, is $9.8 million. As the discharge location for this
option is on -site, no additional easements must be obtained and there are no costs associated
with easement maintenance. The full cost evaluation for this alternative is included in Appendix G.
3.5 Disposal Combinations
Disposal via wastewater reuse has been determined to be fiscally unfeasible, even in combination
with the surface water discharge option. Agricultural land -based application in combination with
surface water discharge could be further pursued. Agreements with local agricultural producers
can be developed and partial land -based disposal could be adopted in the future. Table 7
summarizes the feasibility of each option presented.

Present Value Cost Analysis
As outlined in the EAA Guidance Document, a 20-year present value cost analysis was performed
for all disposal alternatives. The full cost analyses for each option are presented in Appendices C
through G. The 2023 Environmental Protection Agency discount rate was 2.50%. Table 8
summarizes the cost for each alternative, broken down by capital and recurring costs in millions
of dollars. Connection to an Existing Wastewater Treatment System, Land Application,
Wastewater Reuse, and Direct Discharge to Surface Waters are Alternatives A, B, C, and D,
respectively. Options 1 and 2 of Alternative B refer to a County -owned land application system
and an agricultural land application system, respectively.

CDM Smith developed the capital costs for the above alternatives in general accordance with
A k
guidelines established by the Association for the Advancement of Cost Estimating, or AACE
(formerly Association for the Advancement of Cost Estimating International or AACEI) and is
most accurately described as a Class 4 cost estimate. Class 4 cost estimates are appropriate for
engineering designs between 1% and 15% complete, with expected variations ranging from -30%
to +50%. The basic assumptions used during the cost calculations can be summarized as follows:
■ Taxes are approximately 6.75% of the permanent material cost.
■ Mobilization and field general conditions are approximately 10.5% of the subtotal
'^
allowances including labor, material, and equipment
• Bonds, permitting, and insurance are 5% of subtotal allowances including labor, material,
and equipment
■ Contractor overhead/profit total is approximately 10% on the subtotal allowances
including labor, material, and equipment.
■ Construction contingency is 15% on the final subtotal.
Aft
■ Design and Construction Engineering is 18% on the total construction cost.

The capital costs should be escalated by 70/o per year until the midpoint of project construction.

Subject: USGS response to DWR USGS Low Flows request # 2022-196 (dated 2022/05/24) for
Clear Creek Henderson County ... RE: [EXTERNAL] Low -flow request approval
Anish,
Ak
... In response to your inquiry about the low -flow characteristics for a location on Clear Creek immediately downstream
from Laurel Branch in eastern Henderson County, the following information is provided:
FOR THE RECORD: The point of interest is a stream location on Clear Creek using the location coordinates (listed below)
provided as part of the request information provided by the requestor. However, initial email correspondence related
to this low -flow request received from the requestor on O5/17/2022 identified several potential points of interest being
examined related to this project work. The estimated low -flow characteristics provided below are specific to the point
of interest on Clear Creek identified using the location coordinates mentioned in this response. However, the range of
low -flow yields used for this response can also be considered applicable to the alternative points of interest. Users
would only need to apply the range of low -flow yields using the drainage areas that can be determined via the USGS
.� StreamStats application for North Carolina (https://streamstats.usgs.gov/ss/).
A check of the low -flow files here at the USGS South Atlantic Water Science Center (SAWSC, Raleigh office) does not
�► indicate a previous low -flow determination for the specific point of interest, identified by the lat/long coordinates
(35.3753,-82.4111) provided via email dated 05/24/2022 from the DWR USGS Low Flows portal following your request
submission.
No USGS discharge records are known to exist for the point of interest.
In the absence of site -specific discharge records sufficient for aloes -flow analysis, estimates of low -flow characteristics at
ungaged locations are determined by assessing a range in the low -flow yields (expressed as flow per square mile
,.� drainage area, or cfsm) at nearby sites where estimates have been determined.
Aft A basin delineation completed using the online USGS StreamStats application for North Carolina
(https:/Istreamstats.usgs.gov/ss/) indicates the drainage area for the point of interest (StreamStats adjusted
coordinates 35.37526,-82,41110 NAD83) is 34.1 sgmi, which confirms the corrected drainage area you mentioned in
your follow-up email dated 05/23/2022 following your request submission.
Ask
av For streams in Henderson County, low -flow characteristics published by the USGS are provided in the following
reports:
Ak (1) The first is a statewide report completed in the early 1990's. It is USGS Water -Supply Paper 2403, "Low -flow
Ak characteristics of streams in North Carolina" (Giese and Mason, 1993). An online version of the report is available at
http://pubs.usgs.gov/wsp/2403/"report.pdf. The report provides the low -flow characteristics (based on data through
1988) via regional relations and at -site values for sites with drainage basins between 1 and 400 sgmi and not considered
r� or known to be affected by regulation and/or diversions.
Aft
Aft

(2) The second is a statewide report published in March 2015. It is USGS Scientific Investigations Report 2015-5001,
"Low -flow characteristics and flow -duration statistics for selected USGS continuous -record streamgaging stations in
North Carolina through 2012" (Weaver, 2015). The report is available online at
http://Pubs.usgs.gov/sir/2015/5001/. The report provides updated low -flow characteristics and flow -duration statistics
for 266 active (as of 2012 water year) and discontinued streamgages across the state where a minimum of 10 climatic
years discharge records were available for flow analyses.
Low -flow characteristics estimated for point of interest:
Inspection of the reports indicates the presence of eleven (11) nearby selected USGS partial -record sites (8) and
continuous -record streamgages (3) across eastern Henderson County and fringes of adjacent surrounding counties
where low -flow characteristics have previously been published. Among these 11 index sites, the low -flow discharge
yields for the indicated flow statistics are as follows:
Annual 7Q10 low -flow yields =_> from 0.17 to 0.7 cfsm (average about 0.44 cfsm, median about 0.45 cfsm)
Annual 30Q2 low -flow yields =_> from 0.39 to 1.3 cfsm (average about 0.83 cfsm, median about 0.77 cfsm)
Winter 7Q10 low -flow yields =_> from 0.25 to 1.3 cfsm (average about 0.63 cfsm, median about 0.57 cfsm)
Annual 742 low -flow yields =_> from 0.31 to 1.2 cfsm (average about 0.76 cfsm, median about 0.71 cfsm)
Average annual discharge yields =_> from 1.2 to 2.4 cfsm (average about 1.7 cfsm, median about 1.5 cfsm)
Application of the above range in yields to the drainage area (34.1 sgmi) for the point of interest results in the following
estimated low -flow discharges:
Annual 7Q10 low -flow discharges =_> from 5.8 to 23.9 cfs (average about 15 cfs, median about 15.3 cfs)
Annual 30Q2 low -flow discharges =_> from 13.3 to 44.3 cfs (average about 28.3 cfs, median about 26.3 cfs)
Winter 7Q10 low -flow discharges =_> from 8.5 to 44.3 cfs (average about 21.5 cfs, median about 19.4 cfs)
Annual 70,2 low -flow discharges =_> from 10.6 to 40.9 cfs (average about 25.9 cfs, median about 24.2 cfs)
Average annual discharge discharges =_> from 40.9 to 81.8 cfs (average about 58 cfs, median about 51.2 cfs)
Please note:
(1) The estimated flows are provided in units of cubic feet per second (cfs).
(2) The low -flow yields provided above are rounded to 2 significant figures. Estimated low -flow discharges less than 1
cfs are rounded to 2 significant figures. If between 1 and 100 cfs, then rounded to 1 decimal place; if greater than 100,
then rounded to the nearest whole number (zero decimal places).
(3) The information provided in this message is based on a preliminary assessment and considered provisional, subject
to revision pending collection of future data and further analyses.
These provisional streamflow statistics are provided via the DWR USGS Low Flows cooperative agreement between
the USGS and the N.C. Department of Environmental Quality, Division of Water Resources.
Hope this information is helpful.
Thank you.

RE: Requested Wastewater Availability
Clear Creek Sewer Project
Dear Mr. Buie:
Please allow this letter to serve as a response to your letter dated April 21, 2022, regarding wastewater availability in the
Clear Creek basin. The answers to your questions are provided below:
1. Is the City interested in providing the requested sanitary sewer capacity?
The City of Hendersonville will accept the wastewater from the Clear Creek basin and any other area specified
in the 2000 Mud Creek Agreement (MCA).
2. What would the capital cost to the County be to secure a guaranteed wastewater allocation of 500,000 gallons
per day?
In accordance with Section 7.01(a) of the MCA, the City will, without any cost participation by the County,
treat any and all sanitary sewage that is generated in the Mud Creek Service Area without regard to
allocation or capacity. The Clear Creek basin is within the Mud Creek Service Area.
3. At what point could the County connect to the City's sewer collection system along the US 64 corridor?
In accordance with Section 5.03 of the MCA, the County shall have the right to connect the line(s) to City's
collection system at any appropriate location as provided for in the remaining portion of this Section. The City
of Hendersonville's preference is that this line be directly connected to the existing 24-'inch sewer line near
the confluence of Clear and Wolfpen Creeks.
4. Would there be necessary upgrades to the City's sewer collection system or treatment plant, and would the
County be responsible for funding all or a portion of these upgrades?
Based on existing collection system and wastewater treatment facility flows and the 500,000 gpd Clear Creek
basin projections you provided; no immediate upgrades are anticipated. In accordance with Section 7.02 of
the MCA, the County shall not be obligated to contribute any funds towards the construction, or repair of the
City's current treatment plant or any infrastructure upgrades necessary to provide sewer treatment capacity to
160 Sixth Ave. E. www.hvinc.gov 828.697.3000

r-m!►

serve this area. The City would request that an open channel flow meter be installed as part of a Clear Creek
sewer extension project so that future dry and wet -weather flows can be monitored.
S. What rates would the City charge for wastewater discharge to the City's system including both average daily
flow and peak hour flow?
The MCA does not specifically contemplate charging the County for wastewater flow into our system. It does
stipulate those customers in the service area would be charged the City's outside rate, which is capped per the
MCA at no more than a 60% differential. The current outside rate has a 50% differential. Section 5.03 of the
MCA contains detailed provisions of the means customers will be charged based on how line extensions are
installed and owned (by the City, by the County, or by a third party). If the County wishes to install an open
channel flow meter and be billed directly, the City will engage our rate consultants to establish a municipal or
wholesale rate with mechanisms for peak flow.
I would be remiss if I did not point out the opportunity to involve the Hendersonville Water and Sewer Advisory
Committee in this discussion. Section 3.02 of the MCA states, "the purpose of the Advisory Council shall be to advise
the City and the -County on all matters involving the provision of sewerage treatment serves to the citizens of the
District, as amended. In addition, this may be an opportunity to renegotiate the 2002 Mud Creek Agreement and
establish a comprehensive growth strategy for Hendersonville and Henderson County.
I have attached a copy of the 2000 Mud Creek Agreement for your reference. If you have any further questions or need
additional information, please feel free to contact meat [phone] or [e-mail].

(a) The Mud Creek Service Area. The City will, without any cost participation by the County, treat any and

'lot` other unincorporated areas of the County not within the Service Area or the Cane Creek Expansion Area as its capacity
permits.
Section 7.02 Allocation. The City anticipates that the capacity of the current or new treatment* facility will be adequate to
meet the wastewater treatment needs for the City of Hendersonville, the Service Area, and the Cane Creek Expansion
Area for the duration of this Agreement. There is therefore no specific allocation being granted to the County by the City
pursuant to this Agreement. The City agrees to provide the entire wastewater treatment capacity needed for the City, the
Service Area, and the Cane Creek Expansion Area at its sole cost without any participation by the County or the District
for the duration of this Agreement. The County shall not be obligated to contribute any money towards the construction
AMN or repair of the City's current treatment plant, its planned new treatment plant, any other treatment plants, or any
infrastructure upgrades necessary to provide the sewer treatment capacity as contemplated by this Agreement. The

there is insufficient treatment capacity in any current or future sewer treatment facility or infrastructure owned or operated
by the City. In the event the current treatment plant, the new treatment plant, and/or any infrastructure are insufficient, to
serve all of the City of Hendersonville, the Service Area, and/or the Cane Creek Expansion Area, the City agrees, at its
,�►, sole cost, to take whatever steps are necessary to secure additional treatment capacity, whether that be by expanding any
plant or infrastructure owned or operated by the City, building a new plant or infrastructure, or contracting for sewerage
treatment capacity from another provider.

of its sewer treatment facilities and in the performance of this Agreement. However, it is acknowledged that the City must
provide treatment services in accordance with applicable State and Federal Laws, and must also comply with any order
issued by courts having competent jurisdiction. The County and the District agree that any orders issued by any State or
Federal Regulatory Agency, and any order issued by any court of competent jurisdiction regarding the operation of the
City's sewer treatment facilities, whether constructed and operated now or in the future, will take precedence over any
obligations of the City to perform under the teens of this Agreement. The City agrees that it will immediately notify the
�► County in writing of any such orders anticipated or received. If any such orders hinder the ability of the City to perform,
the City shall continue to perform this Agreement to the extent possible; proceed with due haste, due diligence, and good
faith to put itself in a position to be able to fully perform this Agreement; and apply any restrictions imposed by or
�+ resulting from said orders uniformly to all customers, regardless of whether they are located within the City limits or not.
In no event shall the County be required to participate in the cost to comply with any order of any court, or any mandate
issued by any State or Federal agency.
Section 7.04 Annual Report. The City shall semi-annually for the first two years after the date of the Agreement and
annually thereafter, within sixty days of the anniversary date of this Agreement, provide to the County a report showing
its number of customers, treatment capacity available in any and all plants providing sewer treatment services on the

any other information reasonably necessary to apprise the County of the City's status and ability to continue to perform its
obligations under this Agreement.

Preface
Soil surveys contain information that affects land use planning in survey areas.
They highlight soil limitations that affect various land uses and provide information
about the properties of the soils in the survey areas. Soil surveys are designed for
many different users, including farmers, ranchers, foresters, agronomists, urban
planners, community officials, engineers, developers, builders, and home buyers.
Also, conservationists, teachers, students, and specialists in recreation, waste
disposal, and pollution control can use the surveys to help them understand,
protect, or enhance the environment.
Various land use regulations of Federal, State, and local governments may impose
special restrictions on land use or land treatment. Soil surveys identify soil
properties that are used in making various land use or land treatment decisions.
The information is intended to help the land users identify and reduce the effects of
soil limitations on various land uses. The landowner or user is responsible for
identifying and complying with existing laws and regulations.
Although soil survey information can be used for general farm, local, and wider area
planning, onsite investigation is needed to supplement this information in some
cases. Examples include soil quality assessments (http://www.nres.usda.gov/wps/
portal/nres/main/soils/health/) and certain conservation and engineering
applications. For more detailed information, contact your local USDA Service Center
(https://offices.sc.egov.usda.govAocator/app?agency=nres) or your NRCS State Soil
Scientist (http://www.nres.usda.gov/wps/portal/nres/detail/soils/contactus/?
cid=nres142p2_053951).
Great differences in soil properties can occur within short distances. Some soils are
seasonally wet or subject to flooding. Some are too unstable to be used as a
foundation for buildings or roads. Clayey or wet soils are poorly suited to use as
septic tank absorption fields. A high water table makes a soil poorly suited to
basements or underground installations.
The National Cooperative Soil Survey is a joint effort of the United States
Department of Agriculture and other Federal agencies, State agencies including the
Agricultural Experiment Stations, and local agencies. The Natural Resources
Conservation Service (NRCS) has leadership for the Federal part of the National
Cooperative Soil Survey.
Information about soils is updated periodically. Updated information is available
through the NRCS Web Soil Survey, the site for official soil survey information.

How Soil Surveys Are Made
Soil surveys are made to provide information about the soils and miscellaneous
areas in a specific area. They include a description of the soils and miscellaneous
areas and their location on the landscape and tables that show soil properties and
limitations affecting various uses. Soil scientists observed the steepness, length,
AWN
and shape of the slopes; the general pattern of drainage; the kinds of crops and
native plants; and the kinds of bedrock. They observed and described many soil
profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The
profile extends from the surface down into the unconsolidated material in which the
soil formed or from the surface down to bedrock. The unconsolidated material is
devoid of roots and other living organisms and has not been changed by other
biological activity.
/-=►
Currently, soils are mapped according to the boundaries of major land resource
r-'MN
areas (MLRAs). MLRAs are geographically associated land resource units that
share common characteristics related to physiography, geology, climate, water
lmq
resources, soils, biological resources, and land uses (USDA, 2006). Soil survey
areas typically consist of parts of one or more MLRA.
The soils and miscellaneous areas in a survey area occur in an orderly pattern that
is related to the geology, landforms, relief, climate, and natural vegetation of the
area. Each kind of soil and miscellaneous area is associated with a particular kind
of landform or with a segment of the landform. By observing the soils and
miscellaneous areas in the survey area and relating their position to specific
segments of the landform, a soil scientist develops a concept, or model, of how they
were formed. Thus, during mapping, this model enables the soil scientist to predict
with a considerable degree of accuracy the kind of soil or miscellaneous area at a
specific location on the landscape.
Commonly, individual soils on the landscape merge into one another as their
characteristics gradually change. To construct an accurate soil map, however, soil
scientists must determine the boundaries between the soils. They can observe only
a limited number of soil profiles. Nevertheless, these observations, supplemented
by an understanding of the soil -vegetation -landscape relationship, are sufficient to
O, verify predictions of the kinds of soil in an area and to determine the boundaries.
Soil scientists recorded the characteristics of the soil profiles that they studied. They
noted soil color, texture, size and shape of soil aggregates, kind and amount of rock
fragments, distribution of plant roots, reaction, and other features that enable them
to identify soils. After describing the soils in the survey area and determining their
properties, the soil scientists assigned the soils to taxonomic classes (units).
Taxonomic classes are concepts. Each taxonomic class has a set of soil
characteristics with precisely defined limits. The classes are used as a basis for
comparison to classify soils systematically. Soil taxonomy, the system of taxonomic
w
classification used in the United States, is based mainly on the kind and character
MON
of soil properties and the arrangement of horizons within the profile. After the soil
L2

scientists classified and named the soils in the survey area, they compared the
individual soils with similar soils in the same taxonomic class in other areas so that
they could confirm data and assemble additional data based on experience and
research.
The objective of soil mapping is not to delineate pure map unit components; the
objective is to separate the landscape into landforms or landform segments that
have similar use and management requirements. Each map unit is defined by a
unique combination of soil components and/or miscellaneous areas in predictable
proportions. Some components may be highly contrasting to the other components
of the map unit. The presence of minor components in a map unit in no way
diminishes the usefulness or accuracy of the data. The delineation of such
landforms and landform segments on the map provides sufficient information for the
development of resource plans. If intensive use of small areas is planned, onsite
investigation is needed to define and locate the soils and miscellaneous areas.
Soil scientists make many field observations in the process of producing a soil map.
The frequency of observation is dependent upon several factors, including scale of
mapping, intensity of mapping, design of map units, complexity of the landscape,
and experience of the soil scientist. Observations are made to test and refine the
soil -landscape model and predictions and to verify the classification of the soils at
specific locations. Once the soil -landscape model is refined, a significantly smaller
number of measurements of individual soil properties are made and recorded.
These measurements may include field measurements, such as those for color,
depth to bedrock, and texture, and laboratory measurements, such as those for
content of sand, silt, clay, salt, and other components. Properties of each soil
typically vary from one point to another across the landscape.
Observations for map unit components are aggregated to develop ranges of
characteristics for the components. The aggregated values are presented. Direct
measurements do not exist for every property presented for every map unit
component. Values for some properties are estimated from combinations of other
properties.
While a soil survey is in progress, samples of some of the soils in the area generally
are collected for laboratory analyses and for engineering tests. Soil scientists
interpret the data from these analyses and tests as well as the field -observed
characteristics and the soil properties to determine the expected behavior of the
soils under different uses. Interpretations for all of the soils are field tested through
observation of the soils in different uses and under different levels of management.
Some interpretations are modified to fit local conditions, and some new
interpretations are developed to meet local needs. Data are assembled from other
sources, such as research information, production records, and field experience of
specialists. For example, data on crop yields under defined levels of management
are assembled from farm records and from field or plot experiments on the same
kinds of soil.
Predictions about soil behavior are based not only on soil properties but also on
such variables as climate and biological activity. Soil conditions are predictable over
long periods of time, but they are not predictable from year to year. For example,
soil scientists can predict with a fairly high degree of accuracy that a given soil will
have a high water table within certain depths in most years, but they cannot predict
that a high water table will always be at a specific level in the soil on a specific date.
After soil scientists located and identified the significant natural bodies of soil in the
survey area, they drew the boundaries of these bodies on aerial photographs and

Custom Soil Resource Report
identified each as a specific map unit. Aerial photographs show trees, buildings,
fields, roads, and rivers, all of which help in locating boundaries accurately.

Map Unit Descriptions
The map units delineated on the detailed soil maps in a soil survey represent the
soils or miscellaneous areas in the survey area. The map unit descriptions, along
with the maps, can be used to determine the composition and properties of a unit.
A map unit delineation on a soil map represents an area dominated by one or more
major kinds of soil or miscellaneous areas. A map unit is identified and named
according to the taxonomic classification of the dominant soils. Within a taxonomic
class there are precisely defined limits for the properties of the soils. On the
landscape, however, the soils are natural phenomena, and they have the
characteristic variability of all natural phenomena. Thus, the range of some
observed properties may extend beyond the limits defined for a taxonomic class.
Areas of soils of a single taxonomic class rarely, if ever, can be mapped without
including areas of other taxonomic classes. Consequently, every map unit is made
up of the soils or miscellaneous areas for which it is named and some minor
components that belong to taxonomic classes other than those of the major soils.
Most minor soils have properties similar to those of the dominant soil or soils in the
map unit, and thus they do not affect use and management. These are called
noncontrasting, or similar, components. They may or may not be mentioned in a
particular map unit description. Other minor components, however, have properties
and behavioral characteristics divergent enough to affect use or to require different
management. These are called contrasting, or dissimilar, components. They
generally are in small areas and could not be mapped separately because of the
scale used. Some small areas of strongly contrasting soils or miscellaneous areas
are identified by a special symbol on the maps. If included in the database for a
given area, the contrasting minor components are identified in the map unit
descriptions along with some characteristics of each. A few areas of minor
components may not have been observed, and consequently they are not
mentioned in the descriptions, especially where the pattern was so complex that it
was impractical to make enough observations to identify all the soils and
miscellaneous areas on the landscape.
The presence of minor components in a map unit in no way diminishes the
usefulness or accuracy of the data. The objective of mapping is not to delineate
pure taxonomic classes but rather to separate the landscape into landforms or
landform segments that have similar use and management requirements. The
delineation of such segments on the map provides sufficient information for the
development of resource plans. If intensive use of small areas is planned, however,
onsite investigation is needed to define and locate the soils and miscellaneous
areas.

Custom Soil Resource Report
AWN
An identifying symbol precedes the map unit name in the map unit descriptions.
IVI`
Each description includes general facts about the unit and gives important soil
properties and qualities.
Soils that have profiles that are almost alike make up a soil series. Except for
differences in texture of the surface layer, all the soils of a series have major
horizons that are similar in composition, thickness, and arrangement.
Soils of one series can differ in texture of the surface layer, slope, stoniness,
salinity, degree of erosion, and other characteristics that affect their use. On the
basis of such differences, a soil series is divided into soil phases. Most of the areas
shown on the detailed soil maps are phases of soil series. The name of a soil phase
commonly indicates a feature that affects use or management. For example, Alpha
silt loam, 0 to 2 percent slopes, is a phase of the Alpha series.
Some map units are made up of two or more major soils or miscellaneous areas.
These map units are complexes, associations, or undifferentiated groups.
A complex consists of two or more soils or miscellaneous areas in such an intricate
pattern or in such small areas that they cannot be shown separately on the maps.
OR'S
The pattern and proportion of the soils or miscellaneous areas are somewhat similar
in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example.
An association is made up of two or more geographically associated soils or
miscellaneous areas that are shown as one unit on the maps. Because of present
or anticipated uses of the map units in the survey area, it was not considered
practical or necessary to map the soils or miscellaneous areas separately. The
pattern and relative proportion of the soils or miscellaneous areas are somewhat
Pas
similar. Alpha -Beta association, 0 to 2 percent slopes, is an example.
r"IN
An undifferentiated group is made up of two or more soils or miscellaneous areas
that could be mapped individually but are mapped as one unit because similar
interpretations can be made for use and management. The pattern and proportion
of the soils or miscellaneous areas in a mapped area are not uniform. An area can
be made up of only one of the major soils or miscellaneous areas, or it can be made
`"°''
up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.
IaIN
Some surveys include miscellaneous areas. Such areas have little or no soil
lab
material and support little or no vegetation. Rock outcrop is an example.

Soil Information for All Uses
Suitabilities and Limitations for Use
The Suitabilities and Limitations for Use section includes various soil interpretations
displayed as thematic maps with a summary table for the soil map units in the
selected area of interest. A single value or rating for each map unit is generated by
aggregating the interpretive ratings of individual map unit components. This
aggregation process is defined for each interpretation.
Waste Management
Waste Management interpretations are tools designed to guide the user in
evaluating soils for use of organic wastes and wastewater as productive resources.
Example interpretations include land application of manure, food processing waste,
and municipal sewage sludge, and disposal of wastewater by irrigation or overland
flow process.
Slow Rate Treatment of Wastewater
Slow rate treatment of wastewater is a process in which wastewater is applied to
land at a rate normally between 0.5 inch and 4.0 inches per week. The application
rate commonly exceeds the rate needed for irrigation of cropland. The applied
wastewater is treated as it moves through the soil. Much of the treated water may
percolate to the ground water, and some enters the atmosphere through
evapotranspiration. The applied water generally is not allowed to run off the surface.
Waterlogging is prevented either through control of the application rate or through
the use of tile drains, or both.
Soil properties are important considerations in areas where soils are used as sites
for the treatment and disposal of organic waste and wastewater. Selection of soils
with properties that favor waste management can help to prevent environmental
damage.
Municipal wastewater is the waste stream from a municipality. It contains domestic
waste and may contain industrial waste. It may have received primary or secondary
treatment. It is rarely untreated sewage. Food -processing wastewater results from
the preparation of fruits, vegetables, milk, cheese, and meats for public
consumption. In places it is high in content of sodium and chloride. The effluent in
41

Custom Soil Resource Report
lagoons and storage ponds is from facilities used to treat or store food -processing
wastewater or domestic or animal waste. Domestic and food -processing wastewater
is very dilute, and the effluent from the facilities that treat or store it commonly is
very low in content of carbonaceous and nitrogenous material; the content of
nitrogen commonly ranges from 10 to 30 milligrams per liter. The wastewater from
animal waste treatment lagoons or storage ponds, however, has much higher
concentrations of these materials, mainly because the manure has not been diluted
as much as the domestic waste. The content of nitrogen in this wastewater
generally ranges from 50 to 2,000 milligrams per liter. When wastewater is applied,
checks should be made to ensure that nitrogen, heavy metals, and salts are not
added in excessive amounts.
The ratings are based on the soil properties that affect absorption, plant growth,
microbial activity, erodibility, and the application of waste. The properties that affect
absorption include the sodium adsorption ratio, depth to a water table, ponding,
available water capacity, saturated hydraulic conductivity (Ksat), depth to bedrock or
a cemented pan, reaction, the cation -exchange capacity, and slope. Reaction, the
sodium adsorption ratio, salinity, and bulk density affect plant growth and microbial
activity. The wind erodibility group, soil erosion factor K, and slope are considered in
estimating the likelihood of wind erosion or water erosion. Stones, cobbles, a water
table, ponding, and flooding can hinder the application of waste. Permanently frozen
soils are unsuitable for waste treatment.
The ratings are both verbal and numerical. Rating class terms indicate the extent to
which the soils are limited by all of the soil features that affect agricultural waste
management. "Not limited" indicates that the soil has features that are very
favorable for the specified use. Good performance and very low maintenance can
be expected. "Somewhat limited" indicates that the soil has features that are
moderately favorable for the specified use. The limitations can be overcome or
minimized by special planning, design, or installation. Fair performance and
moderate maintenance can be expected. "Very limited" indicates that the soil has
one or more features that are unfavorable for the specified use. The limitations
generally cannot be overcome without major soil reclamation, special design, or
expensive installation procedures. Poor performance and high maintenance can be
expected.
Numerical ratings indicate the severity of individual limitations. The ratings are
shown as decimal fractions ranging from 0.01 to 1.00. They indicate gradations
between the point at which a soil feature has the greatest negative impact on the
use (1.00) and the point at which the soil feature is not a limitation (0.00).
The map unit components listed for each map unit in the accompanying Summary
by Map Unit table in Web Soil Survey or the Aggregation Report in Soil Data Viewer
are determined by the aggregation method chosen. An aggregated rating class is
shown for each map unit. The components listed for each map unit are only those
that have the same rating class as listed for the map unit. The percent composition
of each component in a particular map unit is presented to help the user better
understand the percentage of each map unit that has the rating presented.
Other components with different ratings may be present in each map unit. The
ratings for all components, regardless of the map unit aggregated rating, can be
viewed by generating the equivalent report from the Soil Reports tab in Web Soil
42

Custom Soil Resource Report
Survey or from the Soil Data Mart site. Onsite investigation may be needed to
validate these interpretations and to confirm the identity of the soil on a given site.

,^ Date: April 6, 2023
.► Subject: Henderson County
Clear Creek Wastewater Treatment Plant —Sanitary Sewer Collection
�. System Flow and Loading Projection Analysis and Wastewater Treatment Plant
Aft Basis of Design
.t
,. Purpose
,k CDM Smith has been tasked by Henderson County and WGLA Engineering, PLLC (WGLA) to develop
the Engineering Alternatives Analysis and National Pollutant Discharge Elimination System
Aftthe
permit application for Henderson County's Clear Creek wastewater treatment plant
^ (W WTP), which will serve the Edneyville community and adjacent areas. This memorandum
establishes the influent flow and loading criteria for the proposed W WTP. The flow and loading
projections, in addition to other design criteria established herein, will serve as the basis of design
^ for a package style WWTP.
Background
^ Henderson County (the County) proposes to construct a new sanitary sewer collection system,
composed of both gravity and pumped systems to service existing residential and commercial
properties in the unincorporated community of Edneyville, North Carolina. Sanitary sewer
management in this portion of the county is currently composed of private septic systems as well as
^ three existing small package style WWTPs.
0%
To treat the sanitary sewage collected by this new collection system, the County is proposing to
construct a new WWTP that it would own and operate. The new WWTP is proposed to be
constructed on a greenfield parcel totaling approximately 15 acres (parcel to be further subdivided
^
pending discussions with property owner(s)) at the confluence of Clear Creek and Laurel Branch.
^
The proposed WWTP site will have an approximate footprint of 0.5 acres. The W WTP will be a
Aft
"package' -type plant and have the initial capacity to treat 0.2 million gallons per day (MGD) average
day maximum month flow (ADMMF). It is conceptually planned to allow for additional capacity
expansion up to 0.5 MGD in the future via installation of additional package treatment units. The
^
site location with approximate plant footprint is included as Figure 1.

A
The process components for the W WTP are anticipated to include influent screening, a flow
equalization cell, two conventional activated sludge treatment trains, two secondary clarifiers, a
�+ sludge holding tank, and effluent disinfection. No supporting administration or laboratory facilities
are included as part of the initial plant construction, but they may be considered for future
expansions. Final design of the facility will confirm the conceptual treatment process configuration
identified above. Influent pumping will be constructed separately from the treatment plant based
^� on the final profile for the gravity sewer collection system.
.. Speculative Limits
'nk The North Carolina Department of Environmental Quality has provided speculative limits for the
proposed facility discharge to Clear Creek at 0.2 MGD and the anticipated buildout flow of 0.5 MGD
,.� Table 1 presents these speculative limits.

Influent Flow and Loads
Influent Flows
CDM Smith and WGLA established initial expected contributors and sanitary sewer flows, flow
^
projections, and flow peaking factors. These estimated flow projections and peaking factors for the
Edneyville sewer collection system are detailed below in Table 2. Estimates include the flows from ^
three existing package plants that will be abandoned once the sanitary sewer and WWTP have been �.
constructed. Based on the County's current implementation schedule, the new WWTP will be online ^
by the end of 2027. Growth in the area prior to regional sanitary sewer service availability is
expected to be limited; therefore, the 65,000 gallons per day (gpd) is estimated to be accurate for ^
Year 1 of the collection system operation. r•.

Analysis has been done assuming a 20-year life for the facilities. Discussions with the North ^
Carolina Department of Environmental Quality indicate that the WWTP should be designed for ..
treatment of the Average Day Maximum Month Flow (ADMMF) condition, which would be
equivalent to approximately 200,000 gpd in Year 20 of operation. All processes should be designed
to hydraulically pass the peak hourly flow (PHF) with the largest unit out -of -service, in accordance ^
with State of North Carolina reliability requirements (Division of Water Resources Minimum Design ^
Criteria for NPDES Wastewater Facilities and 15A North Carolina Administrative Code 021-1.0124 ^,
Reliability). The influent load analyses subsequently described are based on these influent flow
projections.
Influent Loads
^
As there is no existing sanitary sewer collection system covering the extent of the service area, CDM ^
Smith examined a variety of reference sources and used several different methods to develop a '►
range of mass concentrations, mass loadings, and mass loading peaking factors.
Table 3 summarizes the concentration, mass loads, and peaking factors that will serve as the basis
of design for the proposed WWTP.

Plant Basis of Design
In accordance with the State of North Carolina design and reliability requirements summarized in
r►
Table 4 and preliminary vendor proposals for a package plant, CDM Smith has established the
following basis of design criteria for plant processes and equipment. CDM Smith has also used
various guidance documents and references including Wastewater Engineering: Treatment and
i.
Engineering, Fourth Edition (Metcalf & Eddy 2003), Recommended Standards for Wastewater
Facilities (Great Lakes -Upper Mississippi River Board of State and Provincial Public Health and
Environment Managers 2004), and Design of Municipal Wastewater Treatment Plants, Sixth
Edition(Water Environment Federation, 2017) to determine mixing, aeration, feed, and overflow
requirements. Final design of the facility will confirm the conceptual treatment process
configuration identified previously.
r►
Influent Screening
A.
Influent pumping will be constructed separately from the treatment plant, based on the final profile
for the gravity sewer collection system. However, the packaged plant manufacturer must provide
coarse influent screening prior to the main treatment processes in accordance with Table 5. ^.

The packaged plant manufacturer must provide a tank to attenuate peak flows. A mixing and
aeration system is necessary to maintain solids suspension and prevent septic conditions. This
system should consist of coarse bubble diffusion at 20 cubic feet per minute (cfm) per 1,000 cubic
feet of tank volume. Blowers should be positive displacement type. Pumps will also be required to Oak
transfer tank contents to the main treatment process trains. Table 6 presents the design criteria for
the equalization system.

Secondary Clarifiers
The packaged plant manufacturer must provide tanks for secondary clarification. Tanks may be
rectangular or circular. At ADMMF, each clarifier must have a maximum surface overflow rate of
400 gpd per square foot. At PHF, they must have a maximum surface overflow rate of 1,000 gpd per
.o square foot. Each clarifier should have a minimum sidewater depth of 14 feet unless other means
Ak are included to promote settling. As with the activated sludge train, each secondary clarifier should
be designed to treat half of the ADMMF. Each clarifier should also be able to hydraulically pass the
", PHF while maintaining a freeboard of 12 inches and without submerging the weirs.

.► Supporting electrical equipment, control panels, and instrumentation must be included as part of
„, the packaged WWTP. The plant should be configured in a way that facilitates expansion via
additional packaged treatment plant units. No administration or laboratory facilities are included as
^' part of the initial plant construction.
^
Summary
^ A process flow diagram summarizing the major plant processes is presented as Figure 2. Package
plant vendors will be responsible for providing influent screening, flow equalization, activated
^ sludge treatment, secondary clarification, disinfection, and all supporting systems such as chemical
.k storage and feed and intermediate pumping. An influent pump station will be designed to pump

Concept Proposal for Clear Creek Wastewater Treatment Plant
Revision 1 Added Scope of Supply —Marked in

CDM Smith
.. 4600 Park Road, Unit 240
Charlotte, NC 28209
" Pro -Water Systems, Inc. is pleased to provide the following concept proposal in
r. response to the memorandum issued by CDM Smith to prospective vendors;
dated September 29, 2022.
Strategy for Product Selection
..%
After review and consideration of the memorandum issued, a point of
importance was looking at the ultimate treatment flow and the capacity of the
treatment plant. We are proposing to meet the initial capacity of 200,000
+� gallons per day (GPD) by the equipment proposed and associated budgetary
cost. We are proposing the layout, initial construction, and future construction
be completed by developing 100,000 GPD treatment trains. Ultimately to meet
.. a projected flow of 500,000 GPD by the means of five 100,000 GPD treatment
^` trains integrated into one wastewater treatment plant.
Where treatment trains can be utilized individually or combined based on
actual flows into the treatment plant, which are projected to be in initial years
less the provided 200,000 GPD capacity.
We are proposing a Pro -Water Systems FH-200 treatment system, that will
include the following treatment chambers:
.. 1. Flow Equalization Chamber
.. 2. Sludge Holding Chamber
3. Extended Aeration Chamber
4. Hopper Style Clarifier
5. Disinfection by Chlorine Contact Chamber
The treatment system proposed will meet the basis of design influent
conditions to the speculative limits as stated in the memorandum for the
200,000 GPD and the 500,000 GPD scenarios.

providing ultimately five 100,000 GPD treatment trains. We fully expect
engineering input and changes to occur throughout the approval and final
-ft design process. We are here to address concerns and willing to make
necessary changes to meet the needs of the project.
"' Additionally, within the price is the labor cost of a field erection crew; however,
A, we reserve the right based on the date of this scope of supply to revise this
