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. The information in Table 1 is provided as the Basic Identification of the Project as required in the ..

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. Table 2. Estimated Low -Flow Discharges Low -Flow Discharge 7Q10 Range (cfs) 5.8-23.9 Average (cfs) 15 Median (cfs) 15.3 30Q2 13.3-44.3 28.3 26.3 W7Q10 8.5-44.3 21.5 19.4 7Q2 10.6-40.9 25.9 24.2 Note: cis - cubic feet per second Smith 1-3 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. Table 3. Federal and State Protected Species Common Name Scientific Name Federal Status State Status Bald eagle Heliaeetus leucocephalus BGPA' — Bog turtle Glyptemys muhlenbergii Threatened (S/A)' Threatened Bunched arrowhead Sagittoriafasciculata Endangered Gray bat Myotis grisescens Endangered Endangered Mountain heartleaf Hexastylis contracts — Endangered Mountain sweet pitcherplant Sorracenia rubrassp.lonesii Endangered Endangered Northern long-eared bat Myotis septentrionalis Endangered Threatened Small whorled pogonia Isotria medeoloides Threatened — Swamp pink Helonia bullato Threatened — White irisette Sisyrinchium dichotomum Endangered — Notes: ' Protected by the Bald and Golden Eagle Protection Act z Threatened because of similar appearance; not subject to Section 7 consultation. No designated critical habitat for any species has been found within the project area. Potentially suitable habitat for bunched arrowhead was observed within the proposed project area, between tributaries along Clear Creek. No suitable habitat for all other listed species was observed within the proposed project area. TRth 1-5 1-6 Smith Aft Aft Ask Section 2 Population and Flow Projections 2.1 Projected Population According to the EAA Guidance Document, population projections are required for new or expanding domestic wastewater charges. The population projection through 2045 is shown in Figure 2. Projections were obtained from the North Carolina Office of State Budget and Management, State Demographer's Office. Projected Henderson County Population Totals, 2020-2045 160,000 150,000 140,000 r 0 130,000 a 0 a 120,000 110,000 100,000 2020 2025 2030 2035 2040 Year Figure 2 Henderson County Population Projection 2.2 Projected Flow 2.2.1 System Contributors 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. Smith 2-1 Aft% 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. Table 4.

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. Table S.

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.

Alk ^ Section 3 • Disposal Alternatives ^ 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. ^ ^ .+ mi 3-3 St1'1th ^ 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.

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.

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. Table 7.

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. Ink The capital costs should be escalated by 70/o per year until the midpoint of project construction. ..� CD Smith 4-1 r, Section 4 • Present Value Cost Analysis This page intentionally left blank. 4-2 Smith Smith n-1 nCDM z Smith Leger, Morgan E.

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.

REECE City Clerk f l t , 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 Hendersonville, NC 28792-4328 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.

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.

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 'ah` 5 Custom Soil Resource Report 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. 7 Soil Map The soil map section includes the soil map for the defined area of interest, a list of soil map units on the map and extent of each map unit, and cartographic symbols displayed on the map. Also presented are various metadata about data used to produce the map, and a description of each soil map unit. o.eE AIiG BrC.'HyEH E EwF�k EtlF? h �'� �:l EdE' `� \ Br.E --HyE .�BaB AhG.`l H yE Y: - I�:. jEdE C.

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. 12 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. 13 Custom Soil Resource Report Henderson County, North Carolina AhE—Ashe stony sandy loam, 15 to 25 percent slopes Map Unit Setting !National map unit symbol: IcOw Elevation: 1,400 to 5,000 feet Mean annual precipitation: 45 to 70 inches Mean annual air temperature: 46 to 57 degrees F Frost -free period. 90 to 170 days Farmland classification: Not prime farmland Map Unit Composition Ashe and similar soils: 85 percent Estimates are based on observations, descriptions, and transects of the mapunit.

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. 43 �BrC BrC / —`FIyC o TuE yE �BrC HyEHyE EwF EdF EdE 1 H E BaC BrI AhG y g g AhG , HyE D� EdE Co DeB W\ BrE J- B A TeB BaB HyC ; HyC y HyC EdF HyE BrC Co`.

Jones, PE —County Engineer From: Jonathan Lapsley, PE, PMP .k Anish Luthra, PE ,^ 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. ^ 1 ) ) ) ) ) ) ) )))) )) )) ) ) ) ) ) ) ) ) ) ) ) ) ) ) ) ) ) 1 ) ) ) ) i � .r Clear Creek WWTP Flow/Load Projection Analysis and WWTP Basis of Design Adk April 6, 2023 Page 3 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.

Clear Creek WWTP Flow/Load Projection Analysis and WWTP Basis of Design r April 6, 2023 Oak Page 4 ^ ^ 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•.

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. r►.

Clear Creek WWTP Flow/Load Projection Analysis and WWTP Basis of Design April 6, 2023 Page 6 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. ^. Table 5. Influent Screen Basis of Design Quantity Description/Value 1 mechanical bar screen and 1 manual bar screen Peak Design Flow, MGD 0.5 Material of Construction Type 316 and 316Lstainless steel Screen Opening Size, inches 0.5 Screen Motor Power, horsepower (hp) 1.5 Flow Equalization n 0. 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.

Activated Sludge Trains Speculative NPDES permit limits presented in Table 1 indicate the facility does not need to meet ammonia limits in the near -term (20 years). The facility and equipment should be sized to provide full nitrification within the activated sludge trains. Each train should be designed to treat half of the ADMMF. Each train should also be able to hydraulically pass the PHF while maintaining a freeboard .. of 12 inches. Blowers may be positive displacement or centrifugal type.

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. n.. Clear Creek WWTP Flow/Load Projection Analysis and WWTP Basis of Design April 6, 2023 Page 8 _ Mechanical sludge and scum collectors must be provided. The clarifiers should also be equipped with waste activated sludge (WAS) and return activated sludge (RAS) pumps to waste sludge or circulate sludge back to the aeration basin. Scum pumps should also be provided, with the design points set at the discretion of the manufacturer. Proposed pumps may be airlift or rotodynamic type. The design criteria are summarized in Table S.

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. 2219 Leah Drive Hillsborough, NC www.prowatersystemsinc.com 1.
