Griffin,PE,VP of NC Operations,CDG,Inc. 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 potential 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 Blythe Creek(or McNeely Branch),a tributary to TwelveMile 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) There are no specific restrictions based on stream classification.The stream classification of TwelveMile Creek(11-138) is Class C and is further discussed below. Blythe Creek and McNeely Branch are not listed as not meeting criteria for Class C Waters. 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. CDG WMPOTC—Yarbrough Farms 1 Engineering Alternatives Analysis for Yarbrough Properties 2.1.2 Basinwide WO Plans The applicable basin water quality plan is the 2010 Catawba River Basinwide Water Quality Plan - https://www.deq.nc.gov/about/divisions/water-resources/water-planning/basin-planning/river-basin- plans/catawba#2010CatawbaBasinPlan-4258. 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 Catawba River Subbasin - HUC 03050103-water quality is influenced by land use and densely populated areas with large amounts of impervious surfaces in the upper portion of the subbasin which includes the City of Charlotte.Recommendations for this area of the basin were land conservation and restoration projects. 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 Waxhaw Creek watershed within the Catawba River Subbasin contains the endangered Carolina Heel Splitter mussel.The Waxhaw Creek watershed is not located within the Twelvemile Creek watershed,and planned discharges are not expected to impact the Carolina Heel Splitter. 2.1.4 Stream Characteristics Twelvemile Creek is listed in the 2022 North Carolina Integrated Report and 2024 North Carolina Draft Integrated Report as follows: ITwelvemile Creek 11-138 C 3.0 FW Miles 1:76 From source to North Carolina-South Carolina State Line PARAMETER IR CATEGORY CRITERIA STATUS REASON FOR RATING 303D YEAR Fish Community(Nar,AL,FW) 5 Exceeding Criteria Fair,Poor or Severe 8iociassification U.S. Geological Survey was contacted for low flow stream characteristics of each stream,this data is summarized below and provided in Attachment 2.

Wastewater flow projections for the residential portion of the development are anticipated to be 0.13 MGD average with a 0.33 MGD peak as shown below: Table 3. Projected Wastewater Flows Number #bedrooms Subtotal Townhomes 301 2 602 Design Peak Design Criteria Flow Flow Single family 284 4 1136 gal/day/bedroom MGD MGD Total#Bedrooms 1738 75 0.13 0.33 Since this is a residential development, homes will be constructed in a phased approach, with a projection of approximately 12 single and multi-family homes per month. In addition,the projected 20-year flow will include potential wastewater flow from commercial development as a conservative amount.Projected flows based on time are as follows: Table 4. Projected Flows Per Construction Phase Construction Timeframe Estimated Projected Cumulative Phase Equivalent Flow/Timeframe, Projected Units/Timeframe mgd Flow, mgd Phase 1/Phase 2 Year 2 288 0.065 0.065 Phase 1/Phase 2 Year 4 (Same as 288 0.065 0.13 (20-yr Build Out) Year 20) Each phase of construction will adhere to Union County land development codes including the Union County 2050 Comprehensive Plan. CDG WMPOTC —Yarbrough Farms 3 Engineering Alternatives Analysis for Yarbrough Properties 3.0 EVALUATION OF ALTERNATIVES This development will require the collection and treatment of domestic wastewater for the project toproceed,therefore p q 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,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 forpotential capacity availabilityamenable to the project schedule. These included Union Countyand the p tY Town of Waxhaw. \�1 ` * I Wes*Chapel ati� 1. -i. )" v szr" - - ` S sty 4 t • ' i .' .16,1. <l .-.�- - " White r _ Chestnut lane, f-'- s i" ' `` a 'd' Millbrr;-:lik• • t, / 1P ' _, se..1`. , _ , -1onebridge Golf Club - � Mineral .c a S p i• Springs •� ` • oft air kl -� f •. ,.

Confirmation of capacity restrictions from Union County has not been provided. Union County has requested a submission of information as detailed in the communication included as Attachment 3.Based on CDG's research of DEQ's files,Union County public information and verbal communications CDG WMPOTC —Yarbrough Farms 4 Engineering Alternatives Analysis for Yarbrough Properties with Union County, capacity is not expected within the next 5 years. Therefore, this is not 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 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 330,000 gallons per day and 130,000 average gallons per day, the total annual flow will be 47.5 million gallons.Assumptions were made for this alternative analysis based on nearby currently permitted land application systems. Table 4 below shows the average application rates for nearby land application systems found on the NCDEQ Online GIS NPDES Non-Discharge Permits. Table 5.

The assumed value for this alternative is an average of 53 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). CDG WMPOTC—Yarbrough Farms 5 Engineering Alternatives Analysis for Yarbrough Properties The soils of the nearby land application sites are generally poor to moderately drained,and application rates vary from 13.0 to 24 inches per year.The soils in the proposed area consist of predominantly Tarrus gravelly silty clay loam soils which are generally moderately well drained. For the purpose of this analysis, an average of the application rates of the nearby land application sites is used as the assumed average loading rate. The various soils in the area provide for an average loading rate of 20 inches per year. 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 87 acres of land would be needed for spray irrigation of 60 minutes per day. Incorporating the wetted acreage to total acreage ratio,approximately 140 acres of land would be needed for irrigation. A market rate of$5,500-$11,000 per acre(for large tracts as indicated by Union County GIS) could mean an additional $1,540,000 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 5.4 miles away from the site of the proposed wastewater treatment facility to the east. 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 McNeely Branch or Blythe Creek. The wastewater treatment plant would employ a hybrid fixed film-activated sludge process with a small footprint.The treatment plant and effluent characteristics 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 AquaCFI J TM aerobic moving bed biofilm reactor(MBBR)using high density polyethylene(HDPE) media designed to treat domestic wastewater from the proposed development. Each chamber shall incorporate AquaCELL466TM high density polyethylene media fluidized in the activated sludge process using medium bubble aeration assemblies and positive displacement blowers. The system shall 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 McNeely Branch or Blythe Creek at an outfall located onsite.The expected capital cost for this alternative is approximately$9 million. CDG WMPOTC —Yarbrough Farms 6 Engineering Alternatives Analysis for Yarbrough Properties 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. 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. Table 6.

For the record: 1. The point of interest on Blythe Creek is one of two points of interest located immediately adjacent to each other for which low-flow characteristics were requested on the same date. The second point of interest is on McNeely Branch at its mouth just upstream from its confluence with Blythe Creek. The unit low-flow yields applied to this point of interest on Blythe Creek were identical to the low-flow yields applied to the point of interest on McNeely Branch. 2. This point of interest on Blythe Creek is also in vicinity for a nearby point of interest on Mundys Run just upstream from its confluence with West Fork TwelveMile Creek near Weddington in southwest Union County where low-flow characteristics were estimated in response to a low-flow request(#2023-238, dated 2022/10/12). Because of the similarity in location as well as the availability of index sites in southwest Union County,the approach and unit low-flow yields used for the estimates on Mundys Run were likewise applied to the low- flow estimates for Blythe Creek and McNeely Branch. 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 previously 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 coordinates 34.91850, -80.71690 NAD83) is 0.69 sqmi, which confirms the drainage area submitted as part of the request information. For streams in southwest 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 third is a statewide reportpublished in March 2015. It is USGS Scientific Investigations P g 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 htto://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: There are very limited streamflow records for stream locations within the portion of southwest Union County that drain within the Catawba River basin. Inspection of the above reports indicates the presence of only one downstream continuous-record streamgage on Twelve Mile Creek near Waxhaw in Union County(station id 02146900, NWIS drainage area = 76.5 sqmi, period of continuous record from October 1986 to February 2004)within reasonable vicinity of the point of interest ni having visually similar underlying geologic characteristics. It was judged to use this site for the determination of the low-flow characteristics at the point of interest on Blythe Creek. Based on the most recent published low-flow characteristics for this streamgage, the low-flow discharge yields for the indicated flow statistics are as follows: Annual 7Q10 low-flow yield =0.0009 cfsm Annual 30Q2 low-flow yield =0.0353 cfsm Winter 7Q10 low-flow yield =0.0157 cfsm Annual 7Q2 low-flow yield =0.0157 cfsm Average annual discharge yield =0.95 cfsm Application of the above range in yields to the drainage area (1.59 sqmi)for the point of interest results in the following estimated low-flow discharges: Annual 7Q10 low-flow discharge=0.0006 cfs(rounded down to zero flow) Annual 30Q2 low-flow discharge=0.024 cfs(rounded down to zero flow) Winter 7Q10 low-flow discharge=0.011 cfs(rounded down to zero flow) Annual 7Q2 low-flow discharge=0.011 cfs(rounded down to zero flow) Average annual discharge discharge=0.66 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.
