The region is characterized by steep mountains and broad valleys. Macon County has a current population of approximately 29,000 persons, while Franklin is home to approximatel) 67,0 4k residents. The Town owns and operates water and wastewater systems which serve customers within the Town limits, and in adjacent County areas. In recent years the Town of Franklin, as well as the adjacent unincorporated area, has seen a significant increase in residential and commercial development. As a result of this strong growth, official requests for public water and sewer service have risen dramatically. The Town of Franklin's Wastewater Treatment Facility currently has an NPDES permit (No. NC0021547) to discharge ,1.65 MGD into the Tennessee River (see Appendix). The wastewater treatment plant is located off of State Road 1324, adjacent to the Macon County sanitary landfill. The plant is currently operating at an average daily flow of approximatelyWOMOD. When the plant influent reaches 1.32 MGD (80% of the permit limit), the Town is required by State regulations to submit a plan of action to the State of North Carolina. Due to an exceptionally high level of development in the area, the growth rate and associated wastewater flows are expected to increase significantly in the future. As a result, it is estimated that this 80% mark will be reached within the next few years, and the current plant capacity will be exceeded around the year,2005. Based on population and flow projections that include future annexations and - extensions in the 20-year planning period, coupled with the fact the plant regularly experiences peak flows above 1.65 MGD, it is recommended that the Town increase the treatment facility capacity by 1.65 MGD to a design capacity and NPDES permit limit of 3.3 MGD. Due to the extended period of time required to secure funding, prepare design documents and obtain regulatory approvals, it is recommended that the Town proceed immediately with the process of expanding the wastewater treatment plant. The Environmental Assessment for the project has been through the State Clearinghouse for review with respect to the Environmental Policy Act, and the North Carolina Division of Water Quality has issued a Finding of No Significant Impact (FONSI). A copy of the FONSI is provided in the Appendix to this report. Pal • SECTION 2 EXISTING WATER AND WASTEWATER FACILITIES A. WATER SYSTEM The Town of Franklin owns and operates a public water supply and distribution system under Public Water System (PWS identification No 01-57-010. The water system presently provides service to approximate 2,903 customers, *f which the majority are located within the existing Town of Franklin's corporate limits. The existing water treatment plant utilizes Cartoogechaye Creek as a source of raw water. Cartoogechaye Creek has an average flow of 91.78 MGD. The low flow (7 day-10 year) is 25.59 MGD, with an approximate safe yield of 5.1 MGD (20% of 7Q10). An instream flow study is currently underway to substantiate the safe yield of Cartoogechaye Creek. The treatment plant utilizes a conventional treatment process consisting of coagulation, flocculation, sedimentation and filtration and has a design capacity of 2.0 MGD , Average daily production in 1998-99 was 1.08 MGD, with a maximum daily demand of 1.62 MGD. B. WASTEWATER SYSTEM The Town of Franklin owns and operates a wastewater collection system and treatment plant. A sanitary sewer system consisting of 6-inch to 30-inch diameter gravity sewer lines serves the Town of Franklin and the immediate surrounding area. There are approximately twenty-seven (27) miles of gravity sewer lines in the system. Seven (7) lift stations are presently within the collection system. The table below shows the existing pump stations and respective capacity, construction date and general condition of each station. The collection and transmission system transports the wastewater to the Town's wastewater treatment plant adjacent to the Little Tennessee River. The wastewater treatment plant, pump stations and existing sewer lines are shown in Figures 2A and 2B. 4 a., EXISTING WASTEWATER PUMP STATIONS TOWN OF FRANKLIN Pump Station Approximate Capacity Approximate Construction Date General Condition C.R.

The plant was originally constructed in 1964 at a rated capacity of 750,000 gpd, and was upgraded in 1993 to the oxidation ditch facility with a rated capacity of 1.65 mgd. The facility consists of primary screening, biological treatment in an oxidation ditch, secondary settling, disinfection, and post aeration with effluent discharge to the Little Tennessee River, under NPDES Permit No. 0021547. The effluent limits are 30 mg/1 for BOD and TSS ; Sludge is wasted from the oxidation ditch to an aerobic digester for additional treatment and stabilization. Stabilized sludge from the digester is dewatered on a belt press and the resultant dewatered sludge is disposed in the Macon County solid waste landfill. The plant is permitted for a flow of 1.65 MGD. Flows during 1998-99 averaged 1.05 MGD. The plant is located east of the Little Tennessee River just north of the Town. A schematic of the existing wastewater treatment plant is provided at the end of this section.

MACON COUNTY POPULATION PROJECTIONS �. Historical records of population growth in Macon County over the last ten (10) years were obtained from the North Carolina Office of Budget and Management. That office also provided �• their projections of population growth for Macon County through the planning period (2021). Those figures are listed in Table 3 - 1. Table 3 - 1 Macon County Population Data Year Projected Population % Growth 2001 29,276 - 2006 31,322 7.0 2011 33,368 6.5 2016 35,138 5.3 2021 36,907 5.0 _. B. TOWN OF FRANKLIN POPULATION PROJECTIONS Population projections specifically for the Town of Franklin were not available. In reviewing a, past population growth figures, it is noted that the Town experienced an annual growth rate of 2.6% between 1990 and 1996. However, development of properties in and around the Town is currently accelerating at an exceptionally high rate. Several significant commercial, institutional and residential developers have recently received wastewater allocations from the Town, and other significant allocations are anticipated in the very near future. The wastewater allocations for these developments total 521,650 gpd, and these developments are expected to occur within the first five (5) years of the planning period. A listing of these wastewater allocations are provided in Table 3-2. In addition to this unprecedented development rate in Franklin, the Town has recently received significant grant funds to construct a new gravity sewer interceptor along the Little Tennessee River and Cartoogechaye Creek. The interceptor should be completed within the next two years, .. Mit and it is anticipated that the new sewer interceptor will further increase development of the service area in the future. Due to these factors, it is estimated that the Town's wastewater service area will expand at a rate of approximately 4.2% per year, which is higher than the historical growth rate. Based on this growth rate, Table 3-3 provides population projections for the Town of Franklin. However, it should be noted that the Town expects to provide sewer service to a significant number of customers outside the Town limits and Table 3-3 does not account for those customers outside the current Town limits. Wastewater flow rates for the future service area for the 20 year planning period are provided later in this Section of the report., Table 3 - 2 Wastewater Flow Allocations Town of Franklin Development Vanderwoude Commercial Development Holt - Dowdle Mountain Road - < Gem Convention Center - r,en .. 3cr Ochsener Property (Old Murphy Road) - 44/ South Macon Elementary School - 4.2r.» -CA..- . , Macon County Housing Project (Addington Bridge Rd) - 5 ' acon Bank — cgyp+ • / 19c 4S �i5o 4)6- 3 mo Mountain Systems -• "� �1�Aov_ig,�59 __.___ ky i 1 -� ���-� Cornerstone Presbyterian Church =— +/$'J7 '�-'4) 7' 19(°(o ' -` Great Outdoors RV Park _ -C`D'4"') °U — / !j 0 YO�� `' - Trampis Dowdle - Old Murphy Road - /', Rabbit Creek Park -• 42.2 • West Macon Elementary Schoolrp;.

WASTEWATER SERVICE AREA Since areas in and around the Town will continue to become more heavily populated, increased 'on sewer service will become necessary. The map provided at the end of this section shows the limits of the future service area. This map was taken from the Water and Sewer Management Strategy report prepared for the Town in May 2000. fail The approximate area that receives water and sewer service at present is estimated to be 4,250 acres. The total additional service area for the year 2021 was estimated to be 12,280 acres, or nearly three (3) times the current service area. D. INFILTRATION/INFLOW (I/I) ANALYSIS For the purposes of this report, 90 percent of the water consumption will be assumed to be rig returned to the sewage collection system. Based on a review of water billing records, water plant production reports and wastewater treatment plant flows, it is estimated that the total amount of flow generated by infiltration and inflow (UI) is approximately 31 %. This is based on reviewing the data for the three consecutive wettest months of the review period, which is 'm' January, February and March of 1999. The table and associated calculations below show the determination of the infiltration and inflow for the Town of Franklin.

Utilizing the 380,000 gpd of I/I calculated previously, the estimated I/I in the system equates to NMI 'approximately 1,674 gpd per inch -mile (gpdim) of sewer line. Based on the guidelines issued by the North Carolina Division of Water Quality, infiltration greater than 3,000 gpdim is considered excessive. Therefore, the current amount of I/1 in the Town's sewer system is not considered excessive. For the purposes of this 201 Facilities Plan Amendmeniit will be assumed that the Town will achieve a modest decrease in I/I through their maintenance program. Therefor , 28% I/I will be utilized for wastewater flow projections in this report. E.

WASTEWATER FLOW PROJECTIONS FOR SERVICE AREA Zoo o po,(-) As discussed earlier in this Section, the Town of Franklin and its surrounding area is currently experiencing extremely high development. A listing of wastewater flow allocations for specific developments is provided in Table 3-2 of this Section. For the purposes of estimating future wastewater flows, it' has been assumed that the flow allocations listed in Table 3-2 will comprise the entire increase in wastewater flow during the first five ,(( years of the plarring period. After the year 2006, it is assumed that wastewater flow will increase at a rate of 4.2% per year through continued expansion of the service area shown in the map provided at the end of this Section. 10 fall Table 3-5 tabulates the projected flows for the future sewer service area for the Town of Franklin's Wastewater Treatment Plant. Based on historical wastewater treatment plant flows, a maximum daily flow peaking factor of 1.6 is anticipated. Table 3-5 indicates that the projected average daily wastewater flow for the 20-year planning period is 3.3 mgd. PIM f.'

These alternatives are as follows: 1. Expansion of the existing wastewater treatment plant from 1.65 mgd to 3.3 mgd, with discharge to the Little Tennessee River. 2. Expansion of the existing wastewater treatment plant from 1.65 mgd to 3.3 mgd, with surface disposal utilizing spray irrigation. 3. Expansion of the existing wastewater treatment plant from 1.65 mgd to 3.3 mgd, with surface disposal utilizing drip irrigation.- 4. Reuse of treated effluent through utilization as industrial process water or cooling water. 5. Water Conservation/No Action. 6. Connection to another publicly owned wastewater treatment facility. 7. Connection to a privately owned wastewater treatment facility. 8. Feasibility of utilizing individual subsurface treatment systems. 9. Feasibility of utilizing community subsurface treatment systems. The Environmental Assessment that has been prepared and approved by NCDWQ for this project provides a complete environmental assessment of each of the feasible alternatives. Therefore, this Section will summarize only the cost issues related to each alternative. ALTERNATIVE NO. 1 — EXPAND WWTP AND DISCHARGE TO RIVER The proposed expansion to the wastewater treatment plant includes an influent pump station, relocation of the existing influent screens, a one million gallon aerated flow equalization basin, an additional 1.65 mgd rated oxidation ditch? one (1) additional secondary clarifier and return sludge pump station, expansions to the chlorine contact basin and step aeration facility, installation of a 1.0 meter belt filter press inside the existing belt filter press room, a 500,000 gallon aerobic digester, and an emergency generator. A schematic showing the proposed improvements is provided at the end of this Section. The total project cost estimate for 12 5�)� � cP`-' Alternative No. 1 is $4,702,100. A detailed project cost estimate is provided at the end of this section. ALTERNATIVE NO. 2 — EXPAND WWTP AND DISCHARGE BY SPRAY IRRIGATION Alternative No. 2 includes the expansion of the existing WWTP by 1.65 mgd, an effluent pump station to pump 1.65 mgd of treated effluent to the surface discharge fields, a spray irrigation :Dun) h I i7 u, rn 30 or ux,..te r b cJ an U.�system complete with sprinklers, and a �1(25 million gallons) storage facility for wet and freezing weather storage. Based on the soil analysis included in Appendix B of this report, the best case hydraulic loading rate for the soils in this area is 0.10 gpd/sf. Therefore, it is estimated that 380 acres of effective area will be needed for the spray irrigation field. Taking into consideration setbacks and land for the storage facility, it is estimated that approximately 450 acres of land would need to be purchased for this alternative. The total project cost estimate for Alternative No. 2 is 19,706,390. A detailed project cost estimate is provided at the end of this Section. ALTERNATIVE NO. 3 - EXPAND WWTP AND DISCHARGE BY DRIP IRRIGATION Alternative No. 3 includes the expansion of the existing WWTP by 1.65 mgd, an effluent pump station to pump 1.65 mgd of treated effluent to the surface discharge fields, a drip irrigation system, and a 15-day (25 million gallons) storage facility for wet and freezing weather storage. Based on the soil analysis included in Appendix B of this report, the best case hydraulic loading rate for the soils in this area is 0.10 gpd/sf. Therefore, it is estimated that 380 acres of effective area will be needed for the drip irrigation field. Taking into consideration setbacks and land for the storage facility, it is estimated that approximately 450 acres of land would need to be purchased for this alternative. The total project cost estimate for Alternative No. 3 is $25,048,600. A detailed project cost estimate is provided at the end of this Section. 13 ALTERNATIVE NO. 4 — REUSE (INDUSTRIAL PROCESS OR COOLING WATER) There are no known significant needs for industrial process or cooling water that could receive treated effluent for these types of uses. Therefore, the disposal by effluent by reuse will not be evaluated further. Gar co A7 ALTERNATIVE NO. 5 — WATER CONSERVATION / NO ACTION There are no capital costs associated with Alternative No. 5. The Town currently promotes water conservation on an as -needed basis to preserve water supplies. Although increased water conservation may slightly decrease wastewater flows, it is not practical to expect water conservation measures to eliminate the need to expand the wastewater treatment plant. A decrease in wastewater flow of 5% due to water conservation would decrease the 20-year projected wastewater flow to only approximately 3.1 MGD. Therefore, water conservation alone is not a feasible solution to meet the Town's projected wastewater needs. Since Alternative No. 5 does not meet the Town's projected wastewater needs, it will be eliminated as a potential alternative and will not be further evaluated in this Section. ALTERNATIVE NO. 6 — CONNECTION TO A PUBLICLY OWNED WWTP There are no other publicly owned wastewater treatment facilities within a five (5) mile radius of the Franklin WWTP. This is not a feasible alternative and, therefore, will not be evaluated further. ALTERNATIVE NO. 7— CONNECTION TO A PRIVATELY OWNED WWTP There are no privately owned wastewater treatment facilities that have sufficient reserve capacity to receive the additional 1.65 MGD of wastewater to be generated in the planning period. Therefore, this alternative will not be evaluated further. ALTERNATIVE NO. 8 — FEASIBILITY OF INDIVIDUAL SUBSURFACE SYSTEMS A large portion of the projected wastewater for the planning period is commercial, institutional and industrial. Due to the relatively large wastewater flows typically generated by these types of facilities, individual on -site subsurface systems are generally not feasible due to soil percolation limitations, lack of available land and wastewater characteristics. With respect to the residential development, individual subsurface systems may be feasible, depending on the locations, soil types and availability of land. However, since this alternative is not capable of treating large and/or high strength commercial, institutional and industrial wastewater flows, this alternative will not be evaluated further. ALTERNATIVE NO. 9 - FEASIBILITY OF COMMUNITY SUBSURFACE SYSTEMS A large portion of the projected wastewater for the planning period is commercial, institutional and industrial. Due to the relatively large wastewater flows typically generated by these types of facilities, on -site subsurface systems are generally not feasible due to soil percolation limitations, lack of available land and wastewater characteristics. With respect to the residential development, community subsurface systems may be feasible, depending on the locations, soil types and availability of land. However, since this alternative is not capable of treating large and/or high strength commercial, institutional and industrial wastewater flows, this alternative will not be evaluated further. CONCLUSIONS Based on the results of the Alternatives Analysis, the alternative with the lowest capital cost is Alternative No.1, which includes expansion of the existing wastewater treatment plant to 3.3 MGD, with discharge to the Little Tennessee River. The present value cost analysis included in Appendix A also concludes that this alternative is the most cost effective option available to the Town of Franklin. The Environmental Assessment that was prepared previously and approved by the North Carolina Division of Water Quality also recommended this alternative and concluded that this alternative would have no significant impact on the environment (see FONSI issued by NCDWQ in Appendix C). Therefore, it is recommended that the Town of Franklin proceed with the design, permitting and construction of an expansion to the wastewater treatment plant for a treatment capacity of 3.3 MGD. 15 psi cal Pagi eR► Pet falq TOWN OF FRANKLIN WASTEWATER TREATMENT PLANT EXPANSION AND RIVER DISCHARGE PRELIMINARY COST ESTIMATE - ALTERNATIVE NO. 1 Item Description TOTAL 1 SITEWORK $50,000 — 2 ADDITIONAL INFLUENT PUMP STATION $160,000' 3 YARD PIPING $250,000 _ 4 UPGRADE EXISTING INFLUENT PUMPS $40,000 5 RELOCATE EXISTING SCREENS TO COVERED AREA $56,000 6 GRIT REMOVAL FACILITY $230,000 7 SITEWORK AND ACCESS ROAD FOR NEW HEADWORKS t $15,000 - 8 1 MG AERATED FLOW EQUALIZATION BASIN $380,000 _ 9 OXIDATION DITCH $1,100,000 -, 10 ONE SECONDARY CLARIFIER $400,000 11 RETURN SLUDGE PUMP STATION $160,000 12 CHLORINE CONTACT BASIN ADDITION $30,000 13 STEP AERATION ADDITION $30,000 14 1.0 METER BELT FILTER PRESS AND ACCESSORIES $250,000 15 500,000 GALLON DIGESTER $260,000 . , 16 UPGRADE EXISTING DIGESTER $125,000 17 EMERGENCY GENERATOR $120,000 18 ELECTRICAL $300,000 TOTAL CONSTRUCTION COST $3,956,000 Contingencies $395,600 Engineering Design $245,300 Construction Inspection and Contract Administration $75,200 Legal/Administrative/Easements $30,000 TOTAL PROJECT COST $4�702,100 wol 011 rim 11114 NMI ark aw aq MEI TOWN OF FRANKLIN WASTEWATER TREATMENT PLANT EXPANSION AND SPRAY IRRIGATION PRELIMINARY COST ESTIMATE - ALTERNATIVE NO. 2 Item Description _ TOTAL COST 1 SITEWORK $50,000 2 ADDITIONAL INFLUENT PUMP STATION $160,000 3 YARD PIPING $250,000 4 UPGRADE EXISTING INFLUENT PUMPS $40,000 5 RELOCATE EXISTING SCREENS TO COVERED AREA $56,000 6 GRIT REMOVAL FACILITY $230,000 7 SITEWORK AND ACCESS ROAD FOR NEW HEADWORKS $15,000 8 1 MG AERATED FLOW EQUALIZATION BASIN $380,000 9 OXIDATION DITCH $1,100,000 10 ONE SECONDARY CLARIFIER $400,000 11 RETURN SLUDGE PUMP STATION $160,000 12 CHLORINE CONTACT BASIN ADDITION $30,000 13 STEP AERATION ADDITION $30,000L------' 14 1.0 METER BELT FILTER PRESS AND ACCESSORIES $250,000 15 500,000 GALLON DIGESTER $260,000 16 UPGRADE EXISTING DIGESTER $125,000 17 EMERGENCY GENERATOR $120,000 18 ELECTRICAL $300,000 19 STEP AERATION ADDITION_. �--- $30,000 ------ 20 SPRAY IRRIGAPON PIPING - 336,200 LF ® $S/LF \) $260,000 \ 21 SPRINKLER HEADS.820 @ $50 EA _._._ - ' $41,000 j 22 15 DAY STORAGE FACILITY (25 MG) $10,000,000 " 23 TRANSFER PUMP STATION AND PIPING TO SPRAY FIELDS $500,000 TOTAL CONSTRUCTION COST. $14787,000 Contingencies $1,478,700 Engineering Design $840,690 Construction Inspection and Contract Administration $250,000 >450 acres for drip irrigation @ $5,000/acre =� , $2,250,000 c- Legal/Administrative/Easements $100,000 TOTAL PROJECT COST : I $19706,390 0 aft raN fag Pot fag TOWN OF FRANKLIN WASTEWATER TREATMENT PLANT EXPANSION AND DRIP IRRIGATION PRELINIINARY COST ESTIMATE - ALTERNATIVE NO. 3 Item Description TOTAL COST 1 SITEWORK $50,000 2 ADDITIONAL INFLUENT PUMP STATION $160,000 3 YARD PIPING $250,000 4 UPGRADE EXISTING INFLUENT PUMPS $40,000 5 RELOCATE EXISTING SCREENS TO COVERED AREA $56,000 6 GRIT REMOVAL FACILITY . $230,000 7 SITEWORK AND ACCESS ROAD FOR NEW HEADWORKS $15,000 8 1 MG AERATED FLOW EQUALIZATION BASIN $380,000 9 OXIDATION DITCH $1,100,000 10 ONE SECONDARY CLARIFIER $400,000 11 RETURN SLUDGE PUMP STATION $160,000 12 CHLORINE CONTACT BASIN ADDITION $30,000 13 STEP AERATION ADDITION $30,000 14 1.0 METER BELT FILTER PRESS AND ACCESSORIES $250,000 15 500,000 GALLON DIGESTER $260,000 16 UPGRADE EXISTING DIGESTER $125,000 17 EMERGENCY GENERATOR $120,000 18 ELECTRICAL $300,000 19 STEP AERATION ADDITION $30,000 20 DRIP IRRIGATION SYSTE?v( $3/GALLON—) $4,950,000 21 15 DAY STORAGE FACILITY (25 MG) $10,000,000 22 TRANSFER PUMP STATION AND PIPING TO DISPOSAL FIELDS $500,000 TOTAL CONSTRUCTION COST $19,436,000 Contingencies $1,943,600 Engineering Design $1,069,000 Construction Inspection and Contract Administration $250,000 $2,250,000 4 0 et* for drip irrigation @ $5,000/acre ✓ Legal/Administrative/Easements $100,000 TOTAL PROJECT COST ' $25,048,600 gab OFFICE FILTER/ ROOF •r �v J SCALE 1 ■ 150' C \ ���� �`� \N1 SLUDGE HOLDING TANK ((( • FIGURE 2 EXISTING WASTEWATER TREATMENT PLANT TOWN OF FRANKLIN ASSOCIATES3 ENGINEERING• PLANNING• FINANCE Gill PROPOSED ADDITION TO CHLORINE CONTACT BASIN AND STEP AERATION PROPOSED DISCHARGE LINE k, ±1 SCALE T. 150' PROPOSED 1 MG FLOW EQUALIZATION BASIN PROPOSED SCREENING AND GRIT REMOVAL FACLITY WASTEWATER TREATMENT PLANT EXPANSION TOWN OF FRANKLIN McGill ASSOC I A TES ENGINEERING • PLANNING.

According to the mapping provided in the "Soil Survey of Macon County, North Carolina", prepared by the United States Department of Agriculture, the soils in the vicinity of the wastewater treatment plant are primarily classified as Evard-Cowee-Saunook (Type 3) and Hayesville-Braddock (Type 2). Evard Series soils, as described in the Macon County soil survey, are typically "very deep, well drained, moderately permeable soils". Hayesville soils are described in the Macon County soil report as soils that are "on ridgetops and side slopes in the uplands. Typically, the surface layer is reddish brown clay loam. The subsoil is red clay, clay loam, and loam. The underlying material is multicolored saprolite that has a texture of loam." Braddock soils are described in the Macon County soil report as soils that "are on ridgetops and side slopes on high stream terraces. Typically, the surface layer is reddish brown clay loam. The underlying material is multicolored loam. " These soil characteristics are fairly typical for western North Carolina. Based on conversations with soil scientists with experience in the region, the best -case hydraulic to ding_rate for these types of soils for both spray and drip irrigation disposal systems is 0.10 gpd per square foot Copies of information and maps from the "Soil Survey of Macon County" published by the United States Department of Agriculture are provided at the end of this Appendix for reference.
