2.0 ENGINEERING ALTERNATIVES ANALYSIS
In accordance the 15A NCAC 2H.0105 (c) (2), this Engineering Alternatives Analysis (EAA) has been prepared to
justify the selection of a direct discharge of non-municipal treated domestic wastewater to surface water as the most
environmentally sound alternative selected from all reasonably cost-effective options.
2.1 Eligibility of NPDES Coverage
The proposed discharge will consist of wastewater generated from residential and retail/commercial sources.
Stormwater will be managed through a series of structural controls and discharged separately in accordance with federal,
state, and local regulations. Wastewater will be treated and discharged to South Fork Crooked Creek. This domestic
wastewater discharge is therefore eligible for coverage under the NPDES direct discharge program based upon the
discussion below.
2.1.1 Receiving stream classification restrictions (15A NCAC 2B .0200)
The stream classification of South Fork Crooked Creek (13-17-20-2b) is Class C and is further discussed below.
Waters assigned a Class C classification are protected for uses such as aquatic life propagation,survival,and maintenance
of biological integrity (including fishing and fish), wildlife, secondary contact recreation, and agriculture. Secondary
contact recreation means wading, boating, other uses not involving human body contact with water, and activities
involving human body contact with water where such activities take place on an infrequent,unorganized, or incidental
basis.

2.1.2 Basinwide WQ Plans
The applicable basin water quality plan is the 2020 Yadkin-Pee Dee Basinwide Water Quality Management Plan -
https://www.deq.nc.gov/about/divisions/water-resources/water-planning/basin-planning/river-basin-plans/yadkin-
pee-dee#2022Yadkin-PeeDeeBasinPlan-9780. Based upon review of the Basinwide Plan, this discharge would have no
overall effect on the plan and would be allowed. The Basinwide Plan indicates the Rocky River Watershed — HUC
03040105 -water quality is influenced by regulated point discharges and nonpoint source pollution which includes land
use change, poultry operations, failing septic tanks, and agricultural fertilizer application. Recommendations for this
basin included land conservation, monitoring and ensuring proper maintenance of facilities with NPDES permitted
discharges and improving methods to control unregulated stormwater runoff from agriculture,forestry,and urban areas.
2.1.3 Endangered Species
A review of the Basinwide Plan and a search of the North Carolina Natural Heritage Program database indicated that
the Goose Creek and Duck Creek tributaries of the Rocky River contain the endangered Carolina Heel Splitter
mussel. The Goose Creek Watershed Management Plan was developed to address water quality in the watershed
including a TMDL for fecal coliform:
hugs://www.dey.ne.gov/water-quality/planning/npu/319/watershedmgtplans-9element/goose-creek-wmp-city-charlotte/download.
Planned discharges to South Fork Crooked Creek are not expected to impact the Carolina Heel Splitter.
2.1.4 Stream Characteristics
South Fork Crooked Creek is listed in the 2022 North Carolina Integrated Report and 2024 North Carolina Draft Integrated
Report as follows:

2.2 Population and Flow Projections
This residential development consists of single-family, three (3) bedroom homes with approximately 350 units, two (2)
bedroom townhomes with approximately 145 units,and a clubhouse;another 4.3 acres of land have been set aside for
commercial development as shown on attached Figure 3. Wastewater flow projections for the residential and
commercial portion of the development are anticipated to be 0.12 MGD average with a 0.31 MGD peak as shown

3.0 EVALUATION OF ALTERNATIVES
This development will require the collection and treatment of domestic wastewater for the project to proceed,therefore
no action is considered to be an infeasible alternative with a lost opportunity cost for the land development and local
economics. Alternatives which have been considered in accordance with 15A NCAC 02H.0105 (c) (2) and are further
discussed below,along with potential combinations of alternatives are:
1. Connection to an existing wastewater treatment plant
2. Land application (onsite subsurface system,
pp y m,irrigation)
3. Wastewater Reuse
4. Direct discharge to surface waters
3.1 Connection to an Existing Wastewater Treatment Plant
Connection to an existing sewer system with a collection system nearby would be the most economically feasible and
environmentally
friendly alternative. Existing sewer systems within lines within a five-mile radius were evaluated and
contacted for potential capacity availability amenable to the project schedule. These included Union County,the Town
of Monroe,and the
Town of Indian Trail.

Q
Figure 2. Five Mile Radius of Proposed Project
Based on inquiries of these entities, there are no known public or private systems that have existing sewer lines and/or
capacity within the five-mile radius of the project. In addition, these systems do not plan to provide or are not on track
to provide sewer access/capacity to the area of development within the next 5 years. Therefore, this is not considered
an alternative and the economic feasibility cannot be considered. This site will need to plan for an alternative means of
wastewater disposal.
3.2 Land Application (onsite subsurface system, irrigation)
Land application evaluation is based on 15A NCAC 02T .0500 and other applicable rules. This alternative would not
allow any discharge to surface waters. This alternative would include the design and construction of storage and spray
COG WMPOTC — Poplin Village 4

Engineering Alternatives Analysis for Poplin Village
irrigation equipment for the land application sites in addition to a wastewater treatment facility. The availability of land
suitable for irrigation may mean spray fields in noncontiguous areas across the site tracts, taking buffers and soil
suitability into account.
At a peak rate of approximately 310,000 gallons per day and 120,000 average gallons per day, the total annual flow will
be 43.8 million gallons. Assumptions were made for this alternative analysis based on nearby currently permitted land
application systems in Union County and Cabarrus County.Table 4 below shows the average flow and application rates
for nearby land application systems found on the NCDEQ Online GIS NPDES Non-Discharge Permits.

time slopes
Research of nearby land application sites was used to estimate retention time based on storage requirements. The
assumed value for this alternative is an average of 33 days of storage to meet the requirements of land application
systems by NCDEQ regulations(required five day and 25%daily flow aerated equalization;minimum 30 days of residual
storage).
The soils of the nearby land application sites are generally poorly drained,and application rates vary from 13.0 in/yr to
20.5 in/yr.The soils in the proposed area consist of predominantly Cid channery silt loam soils and Secrest-Cid complex
soils which are generally very poorly drained. For the purpose of this analysis,the application rate from WQ0018497 of
13.0 in/yr will be used as a conservative assumed average loading rate in consideration of the soils.A wetted acreage to
total acreage ratio of 1.6 is used to account for buffers (stream, property lines, slopes, etc.) and poor soils, based on
WQ0043559&WQ0043559 Soil Scientist/Agronomist Reports net usable acreage ratio average.
Using these assumptions, approximately 124 acres of land would be needed for spray irrigation of 60 minutes per day.
Incorporating the wetted acreage to total acreage ratio,approximately 200 acres of land would be needed for irrigation.
A market rate of$12,600-$13,800 per acre(for large tracts as indicated by Union County GIS) could mean an additional
CDG WMPOTC — Poplin Village 5

Engineering Alternatives Analysis for Poplin Village
$2,760,000 in land acquisition for land application. In addition, land for the footprint of 3 storage basins would be
needed along with pump stations to meet the minimum 25% flow equalization, 5-day effluent storage and 30 -day
residual holding requirements of 15A NCAC 02T 0505(i), (o), and (w),increasing the required capacities. In addition,
capital costs for the design and construction of the spray irrigation fields and equipment and additional recurring costs
for the operation and maintenance of appurtenances for spray irrigation would be incurred. Onsite subsurface systems
are not feasible for the planned density and lot sizes of this development and therefore not evaluated.
3.3 Wastewater Reuse
Wastewater reuse is governed by 15A NCAC 02U,which describes the acceptable uses for reclaimed water. To meet
the "beneficial reuse" definition in the regulations,irrigation of public and private landscapes and turf sewer cleaning,
and decorative ponds and fountains are identified as potential reuse opportunities within this residential development.
The closest golf course is approximately 2.8 miles away from the site of the proposed wastewater treatment facility,west
along Highway 74.As part of its operations,WMPOTC plans to incorporate reuse where feasible to reduce the volume
of discharge to the receiving stream. For a reuse opportunity to be a viable solution,it would need to accept or reduce
a significant portion of the estimated wastewater flow.Reuse would require storage capacity as discussed and calculated
above under land application alternative evaluation as well as additional capital costs for the design and construction
and additional recurring costs for the operation and maintenance of appurtenances to enable reuse. In the event
conditions do not allow for reuse, an alternative method of disposal would be needed.
3.4 Direct Discharge to Surface Waters
A direct discharge to surface water would be accomplished through the design and construction of a small wastewater
treatment plant that would be owned and operated by WMPOTC that would discharge treated wastewater to South
Fork Crooked Creek. Since this is a residential development which will be constructed in phases, the preferred option
is to install a system which could be operated as the residential construction phases progress. This would entail
construction of a plant sized at 150,000 gpd wastewater treatment plant employing an integrated fixed film-activated
sludge process (IFAS) with a small footprint. This alternative would allow flexibility in operations as the domestic
wastewater loading increases with residential construction. The treatment plant would be operated and maintained in
accordance with an NPDES permit to meet secondary treatment standards. For this alternative WMPOTC will supply,
install, and operate an AquaPoint AquaFASTM Integrated Fixed-Film Activated Sludge (IFAS)treatment system or an
AquaPoint AquaCELLTM aerobic moving bed biofilm reactor(MBBR) using high density polyethylene (HDPE) media
designed to treat domestic wastewater from the proposed development (See Attachment 4). Each chamber shall
incorporate AquaCELL4661M high density polyethylene media fluidized in the activated sludge process using medium
bubble aeration assemblies and positive displacement blowers. The system will be capable of treating daily wastewater
flow meeting required permit allowances with primary and secondary treatment supplemented with Biological Nutrient
Removal (BNR) as required using modified activated sludge processes.Secondary clarification will follow the activated
sludge system after which disinfection will be accomplished using redundant UV disinfection parallel units. Costs
associated with this alternative include the capital costs of design and installation as well as recurring costs of operation
and maintenance of the treatment unit, including a potential increase in laboratory costs over land application. The
treatment unit would discharge treated effluent to South Fork Crooked Creek at an outfall located onsite.The expected
capital cost for this alternative is approximately$3 million for each phase with a recurring cost of 10%.
3.5 Combinations of Alternatives
As stated above,WMPOTC plans to incorporate reuse where feasible to reduce the volume of discharge to the receiving
stream in addition to the direct discharge to surface waters. While the reuse will not significantly reduce the volume of
its discharge to surface waters, reuse opportunities within the development will allow for a reduction in the discharge
volume. Another combination would be land application during dry seasons when soil is more amenable and stream
flow is lower, thereby reducing the volume of discharge to surface waters. Incorporating a land application system in
conjunction with the wastewater treatment direct discharge would require the design, construction, operation and
maintenance of both alternatives,making the capital and recurring costs not economically feasible.

Engineering Alternatives Analysis for Poplin Village
4.0 CONCLUSION
Table 5 presents a summary of the alternatives which were evaluated for this project. This summary includes a 20-year
Present Value of Costs Analysis (PVCA) cost comparison using preliminary design level effort. The 2024 discount rate
used in the cost analysis was found in EPA's Appendix C of OMB Circular No. A-94 Revised December 28, 2023
(https://www.whitehouse.gov/wp-content/uploads/2023/12/CircularA-94AppendixC.pdf). The PVCA takes into
account capital costs (including land acquisition, equipment, labor, installation, design) as well as recurring costs
(operation and maintenance,laboratory costs assuming a weekly monitoring regime for discharge systems and a monthly
regime for non-discharge systems, operator and support staff, residual disposal, connection fees and subsequent user
fees,permit and compliance fees,utilities). Based upon the analysis of feasible alternatives,a direct discharge to surface
water under an NPDES permit presents the most environmentally and economically feasible alternative for this
residential development.WMPOTC plans to incorporate reuse where feasible to reduce the volume of discharge to the
receiving stream in addition to the direct discharge to surface waters. While the reuse will not significantly reduce the
volume of its discharge to surface waters,reuse opportunities within the development will allow for a reduction in the
discharge volume.

Subject: USGS response to DWR USGS Low Flows request#2024-301 (dated 2023/11/21) for SF Crooked Creek Union
County...RE: [EXTERNAL] Low-flow request approval
Mr. Farmer,
In response to your inquiry about the low-flow characteristics for a location on South Fork Crooked Creek upstream from
North Rocky River Road (NC Secondary Road 1514) approximately 4 miles east-southeast of Indian Trail in west central
Union County, the following information is provided:
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
(35.06903, -80.59549) provided via email dated 11/21/2023 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 a low-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.
A basin delineation completed using the online USGS StreamStats application for North Carolina
(https://streamstats.usgs.gov/ss/) indicates the drainage area for the point of interest(StreamStats adjusted
1

coordinates 35.06898, -80.59549 NAD83) is 11.7 sqmi, which confirms the drainage area submitted as part of the
request information.
For streams in Union County, low-flow characteristics published by the USGS are provided in the following reports:
(1)The first is a statewide report completed in the early 1990's. It is USGS Water-Supply Paper 2403, "Low-flow
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 sqmi and not considered
or known to be affected by regulation and/or diversions.
(2)The second is a basin-wide report for the Rocky River basin published in 2003. It is USGS Water-Resources
Investigations Report 03-4147, "Low-Flow Characteristics and Profiles for the Rocky River in the Yadkin-Pee Dee River
Basin, North Carolina, through 2002" (Weaver and Fine, 2003). An online version of the report is available
through http://pubs.usgs.gov/wri/wri034147/. The report provides the low-flow characteristics (based on data through
2002)for continuous-record gaging stations and partial-record sites within the Rocky River basin. The report also
provides low-flow discharge profiles (7010, 3002, winter 7010, and 7Q2) for the Rocky River from its headwaters in
Mecklenburg County to its mouth.
(3)The third is a statewide report published in March 2015. It is USGS Scientific Investigations Report 2015-5001, "Low-
flow characteristics and flow-duration i 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 climaticyears discharge records were available for
g
flow analyses.
Low-flow characteristics estimated for point of interest:
Inspection of the reports indicates the presence of eight (8) nearby selected USGS partial-record sites (5) and
continuous-record streamgages (3) in general vicinity of the point of interest where low-flow characteristics have
previously been published. Among these 8 index sites, the low-flow discharge yields for the indicated flow statistics are
as follows:
Annual 7010 low-flow yields ==>from 0 to 0.0055 cfsm (average about 0.0008 cfsm, median about 0 cfsm)
Annual 3002 low-flow yields ==>from 0 to 0.045 cfsm (both average and median about 0.023 cfsm)
Winter 7010 low-flow yields ==>from 0 to 0.022 cfsm (average about 0.012 cfsm, median about 0.011 cfsm)
Annual 7Q2 low-flow yields==>from 0 to 0.017 cfsm (average about 0.0094 cfsm, median about 0.0093 cfsm)
Average annual discharge yields==>from 0.72 to 1 cfsm (average about 0.88 cfsm, median about 0.9 cfsm)
Application of the above range in yields to the drainage area (11.7 sqmi) for the point of interest results in the following
estimated low-flow discharges:
Annual 7Q10 low-flow discharges==>from 0 to 0.064 cfs (average about 0.0094 cfs, median about 0 cfs)
Annual 3002 low-flow discharges==>from 0 to 0.53 cfs (both average and median about 0.27 cfs)
Winter 7010 low-flow discharges==>from 0 to 0.26 cfs (average about 0.14 cfs, median about 0.13 cfs)
Annual 7Q2 low-flow discharges==>from 0 to 0.2 cfs(both average and median about 0.11 cfs)
Average annual discharge discharges==>from 8.4 to 11.7 cfs(average about 10.3 cfs, median about 10.5 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.
