The region is characterized by breathtaking views, steep slopes, and numerous recreational opportunities afforded by Deep Creek, the Tuckaseigee River, and the nearby Great Smoky Mountains National Park. The Town exhibits a laid-back atmosphere with walkable streets and local shops to explore. The Great Smoky Mountains Railway is a major tourist attraction, and the four -lane Highway 74 provides convenient access to the area. A recent census estimated the population of Bryson City to be 1,488 in 2018. Its residents work in a variety of fields to serve the local community as well as provide services to visitors. Once a settlement centered around the extraction of natural resources, tourism has become an important and growing segment of the economy. This shift began as far back as the 1970s but has taken some time to further develop. In 1997, the Eastern Band of Cherokee Indians opened a large casino within 10 miles of the Town, and in 2017, a $200 million plan to build 100,000 square feet of convention space and 600-800 additional hotel rooms was approved and has since been constructed. The 2017 American Community Survey estimated that 20% of the civilian labor force are employed in the arts, entertainment, recreation, accommodation, and food service industries. The Town owns and operates a wastewater treatment facility that serves the residents of Bryson City as well as the surrounding areas within Swain County with a permitted capacity to discharge up to 0.6 million gallons per day (MGD) of treated effluent to the Tuckaseigee River under NPDES Permit NC0026557. The treatment facility utilizes the extended aeration waste activated sludge process. Treatment basins consist of extended aeration contact stabilization basins with diffused aeration and a circular clarifier for solids removal. These are housed in two circular steel tanks. Treated effluent flows to a chlorine contact basin for disinfection prior to discharge. Biosolids are stabilized through digestion in aerobic digesters and dewatered on -site using a belt filter press. The dewatered solids are removed from the site and disposed of at a private landfill in north Georgia. The State of North Carolina guidelines 15A NCAC 02T ("2T Rules") direct the permittee to submit an evaluation of their future wastewater treatment, utilization, and disposal needs, as well as outline plans for meeting those needs by expansion or reduction of extraneous flows, prior to exceeding 80% of permitted capacity based on average flow during the last calendar year. In 2019 to date, the monthly average flow of 0.60 MGD was exceeded three times. An annual average of monthly daily discharge from August 2018 to July 2019 revealed that greater than 80% of plant capacity was exceeded. The average for this time period was 0.521 MGD, or 87.5% of plant capacity. Based upon these flow levels, the North Carolina Department of Environmental Quality (NCDEQ), Division of Water Quality has proposed a moratorium disallowing further sewer line extensions. Town of Bryson City ' May 2020 Wastewater Treatment Plant Improvements mcgill Page 1 of 37 Preliminary Engineering Report In response, the Town of Bryson City agreed to complete two engineering studies, a Wastewater Treatment Plant Alternatives Analysis (described by this report) and an Asset Inventory Analysis. The Wastewater Treatment Plant Analysis generally consists of a review and analysis of the condition, capacity, performance, and longevity of the Town's existing wastewater treatment facility, an evaluation of improvement alternatives including facility upgrade, expansion, and replacement, and preparation of a Preliminary Engineering Report (PER) documenting the findings and recommendations. The Asset Inventory Analysis generally consists of the preparation of a system assessment plan and approach, conduction of condition assessments, identification of recommended projects, and preparation of preliminary opinions of probable cost. Both studies are currently underway, and the moratorium has been temporarily suspended. This report describes the critical need for a project to improve the treatment of wastewater in the Town of Bryson City and provides an analysis of proposed alternatives to increasing the plant's capacity. Cost estimates and maps for the recommended alternative are provided. 1-A LOCATION MAO]SON - BUNCOMBE A-nallla nm.. HAYWOOD SWAIN F_ii - _ Bryson City "[GRAHAM -- HENOERSON .

A preliminary evaluation of the Tuckaseigee River, surrounding wetlands, Endangered Species, Threatened Species, Federal Species of Concern, Candidate Species, and soil types has been conducted for the purposes of this study. During the design phase of the project, all appropriate agencies will be contacted, including, but not limited to, the United States Army Corps of Engineers (USACE), the NCDEQ, the United States Fish and Wildlife Service (USFWS), the Eastern Band of Cherokee Indians Tribal Historic Preservation Office (EBCI THPO), and the North Carolina State Historic Preservation Office (NC SHPO). In addition, regulatory bodies will be consulted during the design phase to ensure that construction will not negatively impact the floodplains. 1-C POPULATION TRENDS Swain County has shown a mostly steady increase in population from 1970 to 2015, from 8,835 to 14,856, and is projected to reach 17,517 by 2038. According to the United States Census Bureau, the population of Bryson City was 1,424 people in 2010. The North Carolina State Demographer conducted a more recent estimate in July 2018 that resulted in a population count of 1,488. The growth from 2010 to 2018 was used as a baseline value. It was assumed that future growth would continue at minimum at this rate, which translated to 5.6% over 10 years, or 0.56% per year. The population trends, projections, median household income (MHI), and demographics are displayed in Tables 1-1, 1-2, 1-3, and 1-4 of Appendix 1-C. Median household income and demographic information was obtained from the 2018 American Community Survey. In addition to the steady projected growth rate of 0.56% per year, an increase in population is expected to occur, stemming from the tourism industry. Among the planned developments in the next 20 years are 10 residential taps, four small townhomes, 17 vacation cottages, one art gallery, and a 60-room hotel. 1-D COMMUNITY ENGAGEMENT The project has been discussed at Town Council meetings, which are open to the public. Highlights of the February 19, 2020 meeting was published in the local newspaper, the Smoky Mountain Times, which serves Swain County. The Engineer has and will continue to present improvement alternatives to Council upon request and to solicit input on major design decisions. Town of Bryson City ' May 2020 Wastewater Treatment Plant Improvements mcgill Page 3 of 37 Preliminary Engineering Report SECTION 2: EXISTING FACILITIES The Bryson City Sanitary Sewer System is comprised of the wastewater treatment plant (WWTP), seven lift stations, numerous force mains, manholes, and gravity collection lines, which range in size from 4 to 16 inches in diameter. The WWTP is located in the southwest area of the city limits. Sewage is conveyed via force mains, gravity sewer, and lift stations to the WWTP where it is treated then discharged into the Tuckaseigee River. The linear footage of gravity sewer and force main lines is shown in Table 2-1. Table 2-1 Gravity and Force Main Sewer Line Sizes and Lengths Gravity Sewer Lines Force Main Sewer Lines Size (in.)

A detailed existing site layout of the WWTP is also shown in Appendix 2- A, along with a flow schematic. 2-13 HISTORY The plant was constructed in the 1970s as a package plant with headworks, two activated sludge treatment units, and a chlorine disinfection unit. The blowers are part of the original installation. The belt filter press was a later addition, installed in 2007, and replaced the original sand drying beds to dewater solids. Treatment Unit Number One was rehabilitated in 2009. The influent screens were replaced in 2013; a belt filter press building, and backup power generator were also part of that project. A project in 2018 replaced the thirty -year -old influent pumps and nearly fifty- year -old wet well structure that supplies sanitary sewage to the plant. A relevant history of applicable violations of regulatory requirements is provided in Section 3, Table 3-1. 2-C CONDITION OF EXISTING FACILITIES The plant generally consists of headworks, two activated sludge treatment units, a chlorine disinfection unit, and a belt filter press. Its specific components include a mechanical wedge wire screen, two waste activated sludge treatment units consisting of reaeration zones, secondary clarifiers, and sludge digesters, and a belt press, sludge storage, chlorination, and dechlorination process. The influent pump station delivers sanitary sewage to the plant via an 8-inch force main. The major treatment component descriptions are summarized in Table 2-3.

The aging plant is exhibiting deficiencies in functionality and posing potential safety concerns, as witnessed in field investigations in the past two years. Additionally, the North Carolina Division of Water Resources conducted a Technical Assistance inspection of the plant in July 2018 to assist with identifying the possible cause of issues at the plant in response to the operators reporting concerns they referred to as "biological die -off". The observations of the various site visits noted several deficiencies that are summarized as follows: Influent Screens: The static wedge wire screens are intended to be self-cleaning. This does not appear to be working effectively, and debris must be cleaned from the screens manually using a water hose and brush. The influent screen system does not have a screenings compactor, and a high percentage of the debris pulled from the screens is excessively wet. The system of debris removal below the screens is functioning poorly, allowing for much of the debris to land on the ground and eventually be diverted back into the drain and subsequently to the lift station. Blowers: The blower room has inadequate ventilation, subjecting all equipment and electrical components within the room to very high heat. The Hoffman blowers in place are more than 30 years old and replacement parts are difficult to obtain. Based upon information available from Hoffman, each of the blowers has marginal capacity to meet the aeration demands of the system. This assumes the blowers are working at the capacity when purchased, which is probably not the case due to the age of each unit. The blowers are undersized, especially during the warmer summer months when air transfer is less efficient. A leak in the underground air lines between the blower building and the treatment tanks was evidenced by the observation of air bubbles on the surface of the ground. Chemical Treatment: The sodium hypochlorite and sodium thiosulfate pump stations each contain only one chemical pump. The pumps themselves are not pacing pumps and were not on GFCI receptacles. Only one eyewash station was present. Electrical conduits, boxes, and other appurtenances have heavy corrosion, and some of the conduits are loose and falling. Other equipment on the site is powered from outlets in the chemical treatment building via extension cords lying loosely across the ground and through open doors and broken windows. These also are not on GFCI circuits. The chemical rooms do not appear to have working ventilation. Chlorine Contact: The chlorine contact basin appears to have a significant buildup of floating solids and grease. There were obvious solids being carried over the outlet weir in the plant effluent. Process failure is apparent, as evidenced by debris and sludge present in the contact chamber. Flow appears to exceed the capacity of the chamber. Electricity for the process is supplied through extension cords at the press building. Aeration: The various aeration drop pipes (drop pipes with diffusers) seem to be working differently at each location within the basin. This indicates these may not be in good condition Town of Bryson City ' May 2020 Wastewater Treatment Plant Improvements mcgill Page 6 of 37 Preliminary Engineering Report and therefore good air distribution out of each of the drop pipes is not being achieved. Dissolved oxygen (DO) was <1 mg/I in both WWTPs but should ideally be 1-3 mg/I. This indicates that blowers may not be functioning properly or may not be of sufficient capacity. Composite Sampler: The influent and effluent samplers are not flow -paced. Electrical System: The existing service at the treatment plant is 120/208V, 3 phase, 4 wire and was upgraded in 2013 during the project for the belt filter press building. The service was increased to 800A and routed to a metering point outside the belt filter press building. A 150kW standby generator and automatic transfer switch was also added as part of that project. The automatic transfer switch and new main switchboard were installed inside the belt filter press building in the press room. The main switchboard has a 400A feeder that was used to repower the existing switchboard in the blower building, that powers all the existing loads in the plant. The existing generator and electrical service are sized specific to the existing treatment plant loads, without much extra capacity. When the treatment plant is upgraded, the electrical service and the generator will likely need to increase in size in order to accommodate the new power requirements. The existing service equipment is located in the same room as the belt filter press and is covered with overspray from that process (refer to the picture in the Appendix). The blower building houses the original electrical equipment for the treatment plant, from the 1970's. The original electrical equipment is outdated and will need to be replaced eventually. The original control panel for the treatment plant is in the blower building and still controls and powers all the equipment on the packaged treatment plant. There is no starting compensation on any of the motor loads, even the 75 hp blowers do not have starting compensation. Monthly average daily discharges since 2018 are shown in Table 2-1 and Figure 2-1. The annual average daily discharge of the wastewater plant in 2018 was 0.455 MGD, which corresponds to approximately 76% of the plant's hydraulic capacity. The months of February, March, and April each show a monthly average daily discharge that exceeds the plant's treatment capacity of 0.6 MGD. The results are also displayed in graphical form in Figure 2-1.

The top ten bulk/industrial users for October 2017 are shown as well in hundreds of gallons, assuming 10% consumptive loss. The existing average usage is based on billing data from the Town. This was separated into two categories: residential users and non-residential/bulk users. It was assumed that non- residential/bulk users corresponded approximately with typical commercial/industrial flows. The specific large commercial/industrial users were not identified because that data was not available for 2018-19. Also, bulk users were not identified specifically because that information was not available. Town of Bryson City May 2020 Wastewater Treatment Plant Improvements mcgill Page 8 of 37 Preliminary Engineering Report The total volume of wastewater treated from 2018-19 was 183,623,380 gallons. The number of residential sewer accounts was 889, and the number of non-residential and bulk sewer accounts was 321. Using billing data, it was determined that during 2018-19, non-residential/bulk users contributed an average of approximately 1.73 times the amount of sewer flow as residential users. Thus, the monthly usage for residential users was 9,964 gallons, and the monthly usage for non-residential users was 20,075 gallons. These values assume all flow can be attributed to the users. This is not actually the case, but all flow will need to be treated, regardless of the source, and thus a distinction from other potential sources was not made in this report. 2-E WATER/ENERGY/WASTE AUDITS A 2019-2020 Asset Inventory Analysis (AIA) project for Bryson City is in progress to identify current deficiencies in the sewer systems based on conditions and age assessment of the major wastewater and collection system facilities. It will provide recommendations, an asset inventory and risk analyses, an Operation and Maintenance Plan, and a Capital Infrastructure Projects plan with recommended wastewater system improvement projects over the next 20-year planning period. A list of projects intended to remove 1/1 and otherwise improve the condition and efficiency of the collection system has been created and is attached as Appendix 8. The Town has also been given a list of immediate needs, which are currently being addressed. Town of Bryson City ' May 2020 Wastewater Treatment Plant Improvements mcgill Page 9 of 37 Preliminary Engineering Report SECTION 3: NEED FOR PROJECT Many factors were considered in the evaluation of the need for the project to ensure the need was correctly identified so an effective solution could be presented. The following sections include an evaluation of health, sanitation, and security; concerns associated with the aging plant; and the reasonable growth capacity that is necessary to meet needs during the planning period. 3-A HEALTH.

The exceedance was attributed to heavy rainfall during the month of December. One possible explanation for the TSS exceedance is that a heavy rain event washed more debris into the wastewater coming into the plant. In 2017, the fecal coliform limit was exceeded, and the nitrogen and phosphorus levels in the effluent were again not monitored as prescribed in the permit. 2018 is the year in which the current NPDES permit was put into effect. It is valid until March 31, 2023. The most notable change is the frequency of nitrogen and phosphorus monitoring, from semi-annually to monthly. Fecal coliform exceedances occurred again during 2018. An explanation for this was not provided. During 2019, flow violations were reported. The plant capacity was exceeded during three months from January to September. 3-13 AGING INFRASTRUCTURE AND FACILITY Per the ongoing AIA project, the collection system consists of gravity and force main sewer lines constructed of various materials including vitrified clay pipe, bituminous fiber (orangeburg), cast iron, polyvinylchloride, and ductile iron pipe. Approximately 54,000 LF (30%) of the gravity sewer lines were installed prior to 1980 and are over 40 years old, and approximately 1,900 LF (18%) of the force main sewer lines are more than 30 years old. Due to the large amount of sewer lines that are over 40 years old and the nature of the material, there are many areas of deficiency within the existing system that experience inflow and infiltration (1/1). The existing condition of the individual components at the wastewater plant listed in Section 2 likely contributed to several of the violations described in 3-A. While 1/1 is a problem, the existing flow must be treated, regardless of the cause. Nevertheless, the current AIA project has resulted in the identification of several areas in the collection system where 1/1 can be reduced. Refer to Appendix 8 for a list of projects and estimated costs. The strength of the wastewater would be expected to increase as a result of being less diluted by 1/1, which would require an effective treatment process to ensure the discharge limits required by the NPDES permit are achieved. Wastewater strength refers to its Biochemical Oxygen Demand (BOD), the amount of TSS, and the Total Coliforms and Fecal Coliforms. The yearly averages for BOD and TSS for the wastewater entering the plant in 2018 and 2019, 211.5 and 182.8 mg/L BOD and 203.7 and 181.2 mg/L TSS, fall in what is typically considered an average range for a municipal plant. The current NPDES permit expires March 31, 2023 and requires the monthly average BOD and TSS concentrations be no higher than 30 mg/L. The monthly average fecal coliform limit is 200/100 ml. Town of Bryson City ' May 2020 Wastewater Treatment Plant Improvements mcgill Page 11 of 37 Preliminary Engineering Report 3-C REASONABLE GROWTH Section 1 presented the expected population growth for Bryson City over the 20-year planning period. The baseline population growth assumption was determined to be 0.56% per year. This was used to calculate flow projections based on population increase. The known planned developments in Table 3-2 for Bryson City were incorporated into the flow projections as well. To account for the anticipated rise in tourism in the area, it was assumed that such developments would occur every five years over the planning period. Table 3-2 Town of Bryson City Planned Developments as of November 2019 Structure Type Number of Units Flow Rate per Unit Flow Rate per Day 10 residential taps 20 bedrooms 120 gpd/bedroom 2,400 gpd 4 small townhomes 1 bedroom each 120 gpd/bedroom 480 gpd 17 vacation cottages 17 units 200 gallons/unit 3,400 gpd Art gallery 2 restrooms 125 gallons/fixture 250 gpd Hotel 60 rooms 120 gallons/room 7,200 gpd A statistical analysis of the plant's average daily flow rates from January 2018 through September 2019 was performed using a probability analysis. Long-term raw wastewater flow usually follows approximately a slightly skewed normal distribution. The "design capacity" can be represented by the hydraulic load value that is one standard deviation above the median. This value, 0.628 MGD, represents the current design capacity of the system. The additional flow anticipated from population growth projected for 2040 was estimated using the Alternate Method developed by EPA. A value of 120 gallons per capita per day was multiplied by the additional population expected during the planning period. This flow was added to the current design capacity to obtain a projected 2040 average flow rate of 0.651 MGD. This value is the design average flow rate for the wastewater system improvements. Two years of flow rate data were analyzed to determine the peaking factor. The peaking factor is determined by dividing the maximum daily flow that year by the average daily flow for that year. For 2018, the peaking factor was 2.20, and for 2019, the peaking factor was 2.11. The peaking factor used to estimate design capacity is an average of these two values, 2.15. Multiplying this by the design average flow rate of 0.651 MGD yields a peak flow rate of 1.40 MGD. The design average flow rate and the peaking factor were used to estimate a new design capacity. The design capacity should be significantly larger than the design average flow rate to allow for peaks in flow as well as future growth. The 2T Rules state that prior to exceeding 80 percent of the system's permitted hydraulic capacity (based on the average flow during the last calendar year), the permittee shall submit an engineering evaluation of their future wastewater Town of Bryson City May 2020 ' Wastewater Treatment Plant Improvements MEN Page 12 of 37 Preliminary Engineering Report mcg treatment, utilization, and disposal needs. This is the current situation. The goal is to increase design capacity such that it will not be in this situation again for at least the planning period of the project. Simultaneously, the design capacity should be reasonable in accordance with anticipated flow rates. The design capacity for the purposes of this report and for the 20-year planning period is estimated to be 1.2 MGD Average Daily Flow with a Hydraulic Capacity of 2.5 MGD. At this size, the anticipated design flow in 2040 would be 55% of the design capacity and peak flow would be 56% of hydraulic capacity. Appendix 3-C shows the committed average usage for the first calendar year of the plant. This takes into account the existing developments and the planned developments that are assumed to occur every five years. Town of Bryson City ' May 2020 Wastewater Treatment Plant Improvements mcgill Page 13 of 37 Preliminary Engineering Report SECTION 4: ALTERNATIVES CONSIDERED In order to holistically address all identified improvement needs in Bryson City's sanitary sewer system, it is highly recommended that upgrades of the wastewater treatment facility are performed in concert with collection system improvements intended to specifically remediate inflow and infiltration. The ongoing Asset Inventory and Assessment project, which included qualitative and quantitative field study such as manhole inspections, flow monitoring, smoke testing and CCTV video inspection, has resulted in the identification of at least six areas within the collection system comprising over 28,000 linear feet of gravity sewer in need of immediate correction (see Appendix 8 for detail): 1. Island Street — 3,900 linear feet of gravity sewer in need of replacement or rehabilitation 2. Powell Lumber West — 2,800 linear feet 3. Ramseur Street — 5,000linearfeet 4. Mitchell Street / Bryson Street / Everett Street — 3,600 linearfeet 5. River Street / Everett Street / Thomas Alley / Slope Street — 3,200 linear feet 6. Airport Hill / Lemons Branch / Bryson Walk — 9,800 linear feet The only alternative to the aforementioned 1/1 improvements is the "No Action" alternative, which is not considered feasible given the definitive field confirmation of 1/1 problems in these areas — problems that continue to cause sanitary sewer backups and overflows (public health concerns) and the exacerbation of negative wet -weather influence at the wastewater treatment plant. Since the project and operations/maintenance costs of the 1/1 remediation projects are constant across all WWTP improvement scenarios, this section includes discussion and analysis of alternatives to improvements at the WWTP only. Costs of 1/1 remediation will be addressed again in Section 6. An alternatives analysis was conducted to arrive at a recommendation for expanding the current capacity of the plant. A detailed preliminary design of a new facility is not presented in this report. It will be developed during the engineering design phase of the project. A brief summary of the considered alternatives is provided in Table 4-1. Table 4-1 Descriotion of Alternatives Alternative Description Alternative #1 No Action Alternative #2 Expansion and Renovation of Existing Facility Alternative #3 New Facility on TVA/USFS Property Alternative #4 New Facility on Town Property Alternative #5 New Facility and Renovation of Existing Facility Alternative #6 Connection to an Existing Treatment System Alternative #7 Land Application Alternative #8 Wastewater Reuse Town of Bryson City ' May 2020 Wastewater Treatment Plant Improvements mcg I I Page 14 of 37 Preliminary Engineering Report The following are potential options for treatment processes for expansion of the existing facility or construction of a new facility. The exact processes to be used will not be decided on in this report, but several of these options will be selected as placeholders for the purposes of preparing schematic layouts and cost estimates for the alternatives presented in this section and in the remainder of the report. Table 4-2 Treatment Options Plant Area Specific Description Processes Headworks Influent screen system and grit removal Treatment Single Tank Two new site built steel treatment tanks, each designed for a Package capacity of half of the total design flow capacity of the plant. The System tank would have an external ring for biological treatment using an activated sludge process and could have separate compartments for future BNR if required. The center of the tank has a circular secondary clarifier for solids removal. Typically, sludge return is by air lift pumps using the aeration system. Operation would be the same as the current system so the operation staff would know how to operate it. Typically, the tanks are steel construction but can be concrete if the owner desires. Sequencing Biological treatment to meet the requirements of the NPDES Batch permit limits would be accomplished utilizing a sequencing Reactor batch reactor (SBR) system, which is an activated sludge process where all the biological treatment, including sedimentation, occurs in a single tank. The process is managed/controlled through a computer system and programmable logic controller (PLC) with more sophisticated controls as requested by the Owner. It would be a simple two tank system that provides flexibility of operation and can handle lower flows and higher wastewater strength. It can be adapted in the future for Biological Nutrient Removal (BNR) if required. The SBR system is sized and components selected to meet the required permit limits. Each basin would have an influent line and control valve, a floating surface mixer to mix the basin as required during the appropriate cycles, a floating effluent decanter, and piping. Aeration for the treatment process would be supplied by diffused aeration using retractable diffuser racks. The air would be supplied by positive displacement blowers. The Town of Bryson City ' May 2020 Wastewater Treatment Plant Improvements mcgill Page 15 of 37 Preliminary Engineering Report blowers would be sized to provide adequate air for the system with a single blower off-line and out of service. The following is an example SBR cycle operation: 1. Mixed fill (Anoxic mixing of the influent flow, independent of aeration) 2. React -fill (Anoxic/aeration mixing of the influent flow) 3. React (Batch condition with no influent and aeration/anoxic mixing) 4. Settle (Quiescent solids/liquid separation) 5. Decant/Idle (Effluent withdrawal) 6. Sludge waste (Remove excess biological solids by pumping to the aerobic digesters) Oxidation This option would be a new oxidation ditch designed for the Ditch design flow. It could be expended/modified in the future for BNR if future permit regulations require. The existing new influent pump station would be used. Flow from the ditch would go to two circular secondary clarifiers. The oxidation ditch is easy to operate for a waste activated sludge system and can operate over a large range of influent flow and strength. However, it requires a large footprint. Designing for a deeper sidewater depth (18-feet +/-) would lessen impact of footprint. Tertiary Filtration Tertiary filters, such as, AquaAerobic cloth filters could be Treatment implemented if permit limits require. Disinfection Sodium Referred to as chlorine, sodium hypochlorite is a reliable and Hypochlorite effective disinfectant against a wide spectrum of pathogens. It is more cost-effective than ultraviolet irradiation. It leaves a residual that can prolong the disinfection effect. It is also easy to control the dosage. The residual can have negative effects on aquatic life, however, and dichlorination may be required. All forms of chlorine are highly corrosive and toxic and require safety measures in handling and transporting. It also produces hazardous compounds when it comes in contact with certain types of organic matter in wastewater. Wastewater with high BOD may destabilize the chlorine, thus requiring a higher dosage to achieve adequate disinfection. Ultraviolet UV disinfection can provide effective inactivation of most Irradiation viruses, bacteria, and spores. It may be effective against some cysts and is a physical process that requires less space than other commonly used methods of disinfection. However, Town of Bryson City ' May 2020 Wastewater Treatment Plant Improvements mcgill Page 16 of 37 Preliminary Engineering Report turbidity and TSS can interfere with its effectiveness, and it may require a large number of lamps, which must be maintained. Sludge Landfilling This option is currently being used by the existing plant. Sludge Disposal is dewatered and disposed of at a landfill out of state. The Town has already been informed that costs will increase from $29/ton to $56/ton. This is in addition to the cost of transporting the dewatered sludge to the landfill in north Georgia. The existing belt filter press is not functioning well and would likely need to be replaced if the plant decides to continue with this method of sludge disposal. Alkaline This option would require major upgrades or new equipment, Stabilization depending on the selected solution. The RDP process (RDP Technologies) uses less lime/kiln dust than alkaline stabilization, as external heat is added to the blender. Both processes produce a Class A product under the 503 Rules. The final product can be distributed for beneficial reuse at agronomic rates with no required long-term tracking by the end user or Owner. The new equipment that would be required would be a new belt filter press for dewatering, a lime/alkaline kiln dust silo, a sludge/lime blender, possibly a thermo blender if using the RDP process, various conveyors (belt and/or screw), a storage shed for the final product, and development of a market for end users. The process results in the roughly one ton of residuals produced in the WWTP being increased to two tons for final beneficial reuse as a result of the addition of alkaline kiln dust. It is a proven process, and farmers and end users are typically accepting of the product. The cost is in the $250 to $300/ton range for final product. Thermal This option consists of the installation of a dryer to dry the Drying sludge to 90% or greater percent solids and produces a Class A product under the 503 Rules. The final product could be distributed for beneficial reuse at agronomic rates with no required long-term tracking by the end user or Owner. Development of the market would be required to identify end users to take the final product. This option would require a new belt filter press, a new building and facility, and possibly odor control. Possible project cost is in excess of $2,000,000. Unit Town of Bryson City ' May 2020 Wastewater Treatment Plant Improvements mcgill Page 17 of 37 Preliminary Engineering Report cost is in the $300/ton range or higher. The benefit is that it reduces the volume to be beneficially reused by as much as 70%. An alternative to installation of a sludge dryer at Bryson City may be to transport sludge to Tuckaseigee Water and Sewer Authority who has a sludge dryer already in operation. This feasibility of this option would need to be further investigated during the design phase of the project. Class B Land This option would consist of the establishment of a Class B land Application application program. Residuals would have to be processed to program meet the EPA 503 regulations for Class B, utilizing aerobic digestion and possible lime addition. The Class B product is then land applied at beneficial agronomic rates to fully utilize the nutrients available in the residuals. A permit is required for the process, as well as permits for the receiver sites. The receiver sites can be farmland owned by Bryson City or privately owned. Certain setbacks are required, and no crops for direct human consumption may be grown. Detailed annual reports of the amount of product applied and crops grown is required, as are long-term records of the accumulative heavy metal applications. Farmers typically see significant increase in crop yields. This is the lowest capital and annual cost alternative. Joint This option would be an interlocal agreement with Tuckaseigee Management Water & Sewer Authority (TWSA) for the processing and final disposal of residuals produced at the Bryson City WWTP. It would require a new permit at TWSA to allow them to accept outside residuals. Residuals would have to be hauled to TWSA on a daily or weekly basis. Depending upon how TWSA will accept the residuals, these may have to be hauled as a liquid which would increase hauling cost. 4-A.1 ALTERNATIVE #1: NO ACTION This alternative is a "no action" alternative consisting of making no improvements to the existing wastewater treatment process for Bryson City. It does not address the aging structures and equipment at the plant and the resulting operational issues. It also does not address the requirements issued by the potential Moratorium. Therefore, it is not a viable alternative and will not be considered further. Town of Bryson City ' May 2020 Wastewater Treatment Plant Improvements mcgill Page 18 of 37 Preliminary Engineering Report 4-A.2 ALTERNATIVE #2: EXPANSION AND RENOVATION OF EXISTING FACILITY The existing plant was constructed in the 1970s and is thus approaching 50 years of age. The core activated sludge treatment units consisting of two welded steel tanks, their respective blowers, and aeration piping, are part of the original installation and have not seen significant upgrades. As described in Section 3, the screens are not functioning properly, the output of the blowers is inadequate, underground air piping leakage is evident by visual observation, electrical equipment is corroding and wiring improperly routed, the chlorine contact basin shows a significant buildup of grease and solids, the aeration basin appears to not be achieving good air distribution or ideal dissolved oxygen levels in the aeration zones, and the composite samplers are not flow -paced. Replacement parts on some of the older equipment may be difficult to obtain. The photographs in Appendix 4-A.2 show evidence of the failing processes. Also, the condition of the underground piping is unknown and expected to be in need of repair, as evidenced by air bubbles coming up from the ground and also considering the age of the piping. Alternative #2 involving expansion and renovation of the existing plant was not deemed to be a viable or cost-effective alternative, based on the existing conditions of the equipment and the lack of space to expand the plant capacity at the current site. At minimum, a third process tank would be required. Also, the current NPDES permit expires in 2023. If the new permit or other future permit renewals were to include more stringent effluent requirements, this alternative would not likely provide the means to meet those requirements. Therefore, this alternative was not investigated further. 4-A.3 ALTERNATIVE #3: NEW FACILITY ON TVA/USFS PROPERTY Alternative #3 consists of decommissioning the existing plant and constructing a new plant on property adjacent to the existing plant to the east/southeast. This is part of the same 285-acre parcel on which the existing plant is located. It is owned by the United States Forest Service (USFS) and is under the administration of the Tennessee Valley Authority (TVA). Therefore, it is referred to in this report as the "TVA/USFS Property". Appropriate process technologies, including conventional activated sludge and SBR treatment, at a minimum, will be evaluated. This alternative would provide the additional capacity that is needed both currently and over the 20- year planning period, and there is room for future expansion if needed. Additionally, if future permit requirements have more stringent requirements, the processes can be adapted or expanded to meet these needs. Although portions of the existing plant may be repurposed, such as the treatment tanks and the belt filter press building, this alternative is distinguished from Alternative #2 in that it will be an entirely new treatment facility. 4-13.3 DESIGN CRITERIA (ALTERNATIVE #3 The TVA/USFS property is a logical choice for construction of a new facility due to its proximity to the existing plant and recently installed influent pump station. Town of Bryson City May 2020 Wastewater Treatment Plant Improvements mcgill Page 19 of 37 Preliminary Engineering Report 4-C.3 MAP (ALTERNATIVE #3) Appendix 4-C.3 shows a potential schematic for the new facility with primary treatment components. This example setup includes two field -erected treatment tanks, a new headworks with screening and grit removal, new blowers and blower/electrical building, a new chlorine contact and chemical feed, and a new method of sludge processing, alkaline stabilization. The existing sludge tanks may have potential for use as sludge holding tanks. The existing belt filter press building is relatively new and would be repurposed for the new sludge processing technology. 4-D.3 ENVIRONMENTAL IMPACTS (ALTERNATIVE #3) The proposed alternative includes the construction of a new wastewater treatment plant on the TVA/USFS property adjacent to the existing plant. Because the proposed improvements are located outside of the existing wastewater treatment plant site, new environmental impacts are anticipated by the implementation of this alternative. The project includes an increase in capacity and adds users to the system. The following environmental impacts were explored for the purposes of this report. Floodplains: A cursory flood plain analysis has been completed to identify the usable property, shown in Appendix 4-D.3. The majority of the parcels available for the new plant lies within the 100-year floodplain. A smaller portion lies within the floodway and is thus unusable. The Base Flood Elevation (BFE) is defined by the Federal Emergency Management Agency (FEMA) as the computed elevation to which the flood is anticipated to rise during the base flood, which is the 1-percent annual chance flood or the 100-year flood. The BFE for this site is approximately three feet higher than the ground elevation. Archaeological and Historical Property Issues: Archaeological and historical property usage will be explored during the engineering design phase of the project. Water Quality Impacts: The proposed project will decrease the potential for spills and sewage overflows. There will be positive impacts to water quality based on this and the more effective treatment and resulting higher quality effluent. However, the existing NPDES discharge permit most likely will no longer be applicable when the existing plant is decommissioned, and a new NPDES discharge permit with a higher effluent discharge rate than the existing will be required for the new plant. Air Quality Impacts: The proposed wastewater treatment plant improvements is anticipated to impact air quality temporarily during the construction phase. The long- term impacts to air quality are expected to be minimal. Town of Bryson City ' May 2020 Wastewater Treatment Plant Improvements mcg I I Page 20 of 37 Preliminary Engineering Report Forest Resources: The proposed project should not impact forest land, as it is on the edges of the property and not likely to coincide with areas where construction is occurring. Therefore, the proposed wastewater treatment plant improvements are currently anticipated to have no adverse impacts to forest land. Fish and Wildlife: The proposed project will likely have positive impacts to water quality, aside from the higher permitted flow rates, and there is no known endangered species habitat in the project area. Therefore, the proposed project is not currently expected to have adverse impacts to fish and wildlife, though a more thorough study will be completed in the design phase of the project. 4-E.3 LAND REQUIREMENTS (ALTERNATIVE #3) This property is part of the parcel on which the existing plant is located. A review with TVA for the potential use of the adjacent land for a wastewater treatment plant has been filed and is awaiting a response. The Great Smoky Mountains Railroad right of way may be encroached upon with this alternative and, if so, would require an easement. 4-F.3 POTENTIAL CONSTRUCTION PROBLEMS (ALTERNATIVE #3) The proposed construction site is fairly level and mostly unforested. It is located within the 100- year floodplain, which is a potential construction problem. However, this problem can be mitigated by raising the processes and electrical components above the BFE, which is approximately three feet higher than ground elevation. 4-G.3 SUSTAINABILITY CONSIDERATIONS (ALTERNATIVE #3) Construction of a new facility allows for the planning of sustainable processes. Several topics will be considered in more detail during the design phase, including, at minimum, water and energy efficiency and green infrastructure. 4-G.3.1 WATER AND ENERGY EFFICIENCY (ALTERNATIVE #3) Steps will be taken during the design process to minimize water and energy use at the plant. For example, energy conserving options may include the use of variable speed drives, high efficiency pumps and motors, efficient blower operation, gravity conveyance of process water throughout the plant, and the consideration of Operation and Maintenance (0&M) costs in selecting processes. Water conservation measures will also be considered. One such option is to reuse treated water at the plant for processes that do not require potable water. Town of Bryson City May 2020 Wastewater Treatment Plant Improvements Page 21 of 37 Preliminary Engineering Report mcgill 4-G.3.2 GREEN INFRASTRUCTURE (ALTERNATIVE #3) According to the United States Environmental Protection Agency (EPA), Section 502 of the Clean Water Act defines green infrastructure as the range of measures that use plant or soil systems, permeable pavement or other permeable surfaces or substrates, stormwater harvest and reuse, or landscaping to store, infiltrate, or evapotranspirate stormwater and reduce flows to sewer systems or to surface waters. Some examples of the implementation of these practices include downspout disconnection, rainwater harvesting, rain gardens, planter boxes, bioswales, permeable pavements, green streets and alleys, green parking, green roofs, urban tree canopy, and land conservation. Such techniques, where applicable, will be considered in the design of the new facility. There may be opportunities for implementation in occupied buildings. 4-G.3.3 OTHER (ALTERNATIVE #3 Other aspects of sustainability will be considered during the design phase as well. These may include resiliency, such as installation of a backup power source, and operational simplicity to provide for a more efficient process. 4-H.3 COST ESTIMATES (ALTERNATIVE #3) The preliminary cost estimates for Alternative #3 is provided below in Tables 4-3 and 4-4. This estimate assumes that the existing influent pumping station will be used and that the existing belt filter press building will be repurposed. An example configuration based on the schematic in Appendix 4-C.3 was used as a basis of comparison.

Town of Bryson City ' May 2020 Wastewater Treatment Plant Improvements mcgill Page 23 of 37 Preliminary Engineering Report 4-A.4 ALTERNATIVE #4: NEW FACILITY ON TOWN PROPERTY This alternative proposes the decommissioning of the existing plant and construction of a new facility on property owned by the Town on the north bank of the Tuckaseigee River. The tract is bounded by the Great Smoky Mountains Railway and the river and is referred to in this report as the "Town Property". This alternative would provide the additional capacity that is needed both currently and overthe 20-year planning period, and there is room for future expansion if needed. Additionally, if future permit requirements have more stringent requirements, the processes can be adapted or expanded to meet these needs. 4-13.4 DESIGN CRITERIA (ALTERNATIVE #4) The current influent pump station is located near the existing plant. Due to the Town Property in this alternative being located across the river from the existing plant, incoming sewage would need to be pumped across the river from its current location. If this property is to be used, an analysis of the existing pump station would be required to determine if the existing influent pumps are capable of pumping the sewage across the river. 4-C.4 MAP (ALTERNATIVE #4) Appendix 4-C.4 shows a potential schematic for the new facility with primary treatment components. This example setup includes two field -erected treatment tanks, new headworks with screening and grit removal, a new chlorine contact basin, new sludge digestion and holding area, new laboratory/operations/chemical storage building (s), and an alkaline stabilization process. 4-D.4 ENVIRONMENTAL IMPACTS (ALTERNATIVE #4) The proposed alternative includes the construction of a new wastewater treatment plant on property across the river from the existing plant. Because the proposed improvements are located outside of the existing wastewater treatment plant site, new environmental impacts are anticipated by the implementation of this alternative. The project includes an increase in capacity and adds users to the system. The following environmental impacts were explored for the purposes of this report. Floodplains: A cursory flood plain analysis has been completed to identify the usable property, shown in Figure 4-2. The majority of the parcels available for the new plant lies within the 100-year floodplain. A smaller portion lies within the floodway and is thus unusable. The BFE is approximately five to seven feet higher than the ground elevation for the majority of the site. Town of Bryson City May 2020 Wastewater Treatment Plant Improvements Page 24 of 37 Preliminary Engineering Report mcgill Archaeological and Historical Property Issues: Archaeological and historical property usage will be explored during the engineering design phase of the project. Water Quality Impacts: The proposed project will decrease the potential for spills and sewage overflows. There will be positive impacts to water quality based on this and the more effective treatment and resulting higher quality effluent. However, the existing NPDES discharge permit most likely will no longer be applicable when the existing plant is decommissioned, and a new NPDES discharge permit with a higher effluent discharge rate than the existing will be required for the new plant. Air Quality Impacts: The proposed wastewater treatment plant improvements is anticipated to impact air quality temporarily during the construction phase. The long- term impacts to air quality are expected to be minimal. Forest Resources: The proposed project should not impact forest land, as it is on the edges of the property and not likely to coincide with areas where construction is occurring. Therefore, the proposed wastewater treatment plant improvements are currently anticipated to have no adverse impacts to forest land. Fish and Wildlife: The proposed project will likely have positive impacts to water quality, aside from the higher permitted flow rates, and there is no known endangered species habitat in the project area. Therefore, the proposed project is not currently expected to have adverse impacts to fish and wildlife, though a more thorough study will be completed in the design phase of the project. 4-E.4 LAND REQUIREMENTS (ALTERNATIVE #4 The land proposed for the new facility in this alternative is already owned by the Town and thus is available for its use. However, it is bounded by the Great Smoky Mountains Railroad and the river. If this alternative is selected, multiple railroad easements would need to be obtained, and the scenic view of the railroad would be affected by the treatment facility. 4-F.4 POTENTIAL CONSTRUCTION PROBLEMS (ALTERNATIVE #4 The land is fairly level and mostly unforested but does have a BFE of approximately five to seven feet higher than ground elevation. The processes and electrical components would need to be constructed such that they are above the BFE. Town of Bryson City ' May 2020 Wastewater Treatment Plant Improvements mcgill Page 25 of 37 Preliminary Engineering Report 4-G.4 SUSTAINABILITY CONSIDERATIONS (ALTERNATIVE #4) Construction of a new facility allows for the planning of sustainable processes. Several topics will be considered in more detail during the design phase, including, at minimum, water and energy efficiency and green infrastructure. 4-G.4.1 WATER AND ENERGY EFFICIENCY (ALTERNATIVE #4) Steps will be taken during the design process to minimize water and energy use at the plant. For example, energy conserving options may include the use of variable speed drives, high efficiency pumps and motors, efficient blower operation, gravity conveyance of process water throughout the plant, and the consideration of Operation and Maintenance (O&M) costs in selecting processes. Water conservation measures will also be considered. One such option is to reuse treated water at the plant for processes that do not require potable water. 4-G.4.2 GREEN INFRASTRUCTURE (ALTERNATIVE #4 According to the United States Environmental Protection Agency (EPA), Section 502 of the Clean Water Act defines green infrastructure as the range of measures that use plant or soil systems, permeable pavement or other permeable surfaces or substrates, stormwater harvest and reuse, or landscaping to store, infiltrate, or evapotranspirate stormwater and reduce flows to sewer systems or to surface waters. Some examples of the implementation of these practices include downspout disconnection, rainwater harvesting, rain gardens, planter boxes, bioswales, permeable pavements, green streets and alleys, green parking, green roofs, urban tree canopy, and land conservation. Such techniques, where applicable, will be considered in the design of the new facility. There may be opportunities for implementation in buildings occupied by plant personnel, for example. 4-G.4.3 OTHER (ALTERNATIVE #4) Other aspects of sustainability will be considered during the design phase as well. These may include resiliency, such as installation of a backup power source, and operational simplicity to provide for a more efficient process. 4-H.4 COST ESTIMATES (ALTERNATIVE #4) The preliminary cost estimates for Alternative #4 are shown below in Tables 4-5 and 4-6. This estimate assumes that the existing belt filter press building will be repurposed, and that the existing influent pumping station can be retrofit to pump across the river. For the purposes of cost estimation, an example configuration based loosely on the schematic in Appendix 4-CA was used as a basis of comparison.

It would result in two fully operational facilities. Several sub - alternatives could be considered with this option, such as utilizing the sludge dewatering equipment at the existing plant and replacing the primary treatment components on the new site, so it was initially considered for its flexibility. However, this option was not further evaluated because it was not deemed a reasonable alternative. The existing plant is in very poor shape, and the cost to renovate it at its current capacity in addition to constructing a new plant is not financially feasible, considering that other, more cost-effective alternatives exist. In addition, it is unconventional to have two fully operational wastewater treatment plants side by side, so it is unknown whether NPDES discharge permits would be granted for this scenario. 4-A.6 ALTERNATIVE #6: CONNECTION TO AN EXISTING TREATMENT SYSTEM Alternative #6 explores the option of sending all or part of sewage from the Bryson City area to another existing wastewater plant. Figure 4-1 shows the location of Bryson City WWTP and the surrounding plants within a ten -mile radius, along with their capacities. Most of these are smaller than the Bryson City facility, with the exception of Cherokee WWTP. Cherokee WWTP is a 6 MGD plant, but it was not designed to accept the flows of another town and is nine miles away over mountainous terrain. Transporting sewage this distance would be cost prohibitive, in addition to concerns about the sewage becoming septic after traveling several miles. Therefore, this alternative was deemed infeasible.

According to 15A NCAC 02T .1109 Residual Management Practices, surface disposal units shall not be located within the 100-year floodplain. The only land currently available for land application of treated wastewater is located within the 100-year floodplain or the floodway of the Tuckaseigee River. Purchase of additional land for such use would likely be cost -prohibitive. Also, this alternative does not address the need to increase capacity of the plant. Therefore, Alternative #6 was deemed infeasible. 4-A.8 ALTERNATIVE #8: WASTEWATER REUSE Reuse of plant effluent water will be investigated during the design and engineering phase as a means of reducing effluent discharge into the river and conserving water. This alternative would not address the need to increase capacity and therefore was not further evaluated at this time. Town of Bryson City May 2020 ,� Wastewater Treatment Plant Improvements EN Page 29 of 37 Preliminary Engineering Report meg SECTION S: SELECTION OF AN ALTERNATIVE 5-A LIFE CYCLE COST ANALYSIS A life cycle cost analysis was prepared to compare the technically feasible alternatives, Alternative #3 and Alternative #4. The analysis is included in Appendix 5-A. 5-B NON -MONETARY FACTORS Non -monetary factors to consider in the selection of an alternative may include social and environmental aspects, such as sustainability considerations, operator training requirements, permit issues, community objections, reduction of greenhouse gas emissions, wetland relocation. Sustainability has been discussed as a factor that will be taken into consideration during the design phase of the project. Several topics will be considered at that time, including, at minimum, water and energy efficiency and green infrastructure. Operator requirements are related to the specific processes that are selected. Since the specific processes included in the schematics and cost estimates in this report are only for the purposes of selecting the best overall solution to the issue presented in the moratorium and are not necessarily the ones that would be selected in the design phase of the project, this is not yet a factor to evaluate. At this time, permitting is expected to be roughly the same for either of the two technically feasible alternatives. Both would require a new outfall into the Tuckaseigee River for the same permitted capacity and discharge rate. Regulatory bodies will be consulted during the design phase to ensure that construction will not negatively impact the floodplains. Wetland relocation is not anticipated for either alternative. Town of Bryson City ' May 2020 Wastewater Treatment Plant Improvements mcg I I Page 30 of 37 Preliminary Engineering Report SECTION 6: PROPOSED PROJECT (RECOMMENDED ALTERNATIVE) Based on the findings of this report, it is recommended that the Town of Bryson City pursue funding of the proposed treatment facility upgrades described in Alternative #3 as soon as possible so that the upgrades can be implemented to resolve the public health issues associated with the existing treatment plant. Due to the proximity of the adjacent land to the existing site and the lesser vertical distance from ground elevations to BFEs in comparison to the Town Property across the river, it is recommended that the TVA/USFS Property be the site of the new wastewater plant. Thus, Alternative #3 was selected instead of Alternative #4. This alternative will provide the additional capacity the plant needs to treat its current flows as well as those predicted for the 20-year planning period. It also provides room for future expansion, which may be required beyond the planning period, and it is possible to modify the processes to meet more stringent permit requirements, if needed. In addition, it preserves the aesthetics of the scenic view across the river to railroad tourists and requires less interference with the railroad in its construction. Based on the additional findings of the ongoing Asset Inventory and Assessment project, some of which may be found in Appendix 8, it is also recommended that several areas of the sanitary sewer collection system are rehabilitated in an effort to mitigate inflow and infiltration. 6-A PRELIMINARY PROJECT DESIGN Detailed design and specific treatment options will be determined in the design and engineering phase of the project. Portions of the existing plant can still be repurposed, such as the belt filter press building, which is relatively new. The existing plant will be decommissioned, and the majority of it will be demolished. Potential treatment processes were discussed in Section 4. For the purposes of this report and cost estimating, specific processes are depicted in the schematic. This potential layout includes the following major treatment processes: • Screening • Grit Removal • Wastewater Treatment Units • Chlorine Disinfection • Alkaline Stabilization For improvements to the collection system, the proposed project includes the replacement or rehabilitation of approximately 28,000 linear feet of 8-inch through 12-inch gravity sewer and over 100 manholes. Rehabilitation includes trenchless methods such as cured -in -place -pipe (CIPP) liners, pipe bursting, and the grouting and lining of manholes with either epoxy or cementitious materials. Replacement will take place with open -cut methods.

Town of Bryson City May 2020 Wastewater Treatment Plant Improvements mcgill Page 36 of 37 Preliminary Engineering Report SECTION 7: CONCLUSIONS AND RECOMMENDATIONS Bryson City Wastewater Treatment Plant is a facility in need of increased capacity and upgrades. The extent of disrepair and the space required to provide the additional capacity needed to meet permit requirements necessitate that a new facility be constructed. It is recommended that this new facility be located on the TVA property adjacent to the existing facility for several reasons. These include advantages of proximity, such as the ability to use the existing, recently installed influent pumping station and the relative ease of rerouting sewage to the new plant, as compared to the property located across the river. Other advantages include a lower base flood elevation than that of the Town property and less disruption to the scenic view from the Great Smoky Mountain Railroad tour than if the facility were to be located on the other property. Preliminary cost estimates demonstrate that the selected alternative is a more cost-effective option. During the design process, the Town will be involved in discussions to determine the best specific treatment processes for the new plant. In order to holistically address all identified improvement needs in Bryson City's sanitary sewer system, it is highly recommended that upgrades of the wastewater treatment facility are performed in concert with collection system improvements intended to specifically remediate inflow and infiltration. The ongoing Asset Inventory and Assessment project, which included qualitative and quantitative field study such as manhole inspections, flow monitoring, smoke testing and CCTV video inspection, has resulted in the identification of at least six areas within the collection system comprising over 28,000 linear feet of gravity sewer in need of immediate correction (see Appendix 8 for detail): 1.

A taxon "in danger of extinction throughout all or a significant portion of its range." T = threatened. A taxon "likely to become endangered within the foreseeable future throughout all or a significant portion of its range." C = candidate. A taxon under consideration for official listing for which there is sufficient information to support listing. (Formerly "C1" candidate species.) BGPA =Bald and Golden Eagle Protection Act. See below. ARS = At Risk Species. Species that are Petitioned, Candidates or Proposed for Listing under the Endangered Species Act. Consultation under Section 7(a)(2) of the ESA is not required for Candidate or Proposed species; although a Conference, as described under Section 7(a)(4) of the ESA is recommended for actions affecting species proposed for listing. FSC=Federal Species of Concern. FSC is an informal term. It is not defined in the federal Endangered Species Act. In North Carolina, the Asheville and Raleigh Field Offices of the US Fish and Wildlife Service (Service) define Federal Species of Concern as those species that appear to be in decline or otherwise in need of conservation and are under consideration for listing or for which there is insufficient information to support listing at this time.Subsumed under the term "FSC" are all species petitioned by outside parties and other selected focal species identified in Service strategic plans, State Wildlife Action Plans, or Natural Heritage Program Lists. T(S/A) = threatened due to similarity of appearance. A taxon that is threatened due to similarity of appearance with another listed species and is listed for its protection. Taxa listed as T(S/A) are not biologically endangered or threatened and are not subject to Section 7 consultation. See below. EXP = experimental population. A taxon listed as experimental (either essential or nonessential). Experimental, nonessential populations of endangered species (e.g., red wolf) are treated as threatened species on public land, for consultation purposes, and as species proposed for listing on private land. P = proposed. Taxa proposed for official listing as endangered or threatened will be noted as "PE" or "PT", respectively. Bald and Golden Eagle Protection Act (BGPA)_ In the July 9, 2007 Federal Register( 72:37346-37372), the bald eagle was declared recovered, and removed (de- listed) from the Federal List of Threatened and Endangered wildlife. This delisting took effect August 8,2007. After delisting, the Bald and Golden Eagle Protection Act (Eagle Act) (16 U.S.C. 668-668d) becomes the primary law protecting bald eagles. The Eagle Act prohibits take of bald and golden eagles and provides a statutory definition of "take" that includes "disturb". The USFWS has developed National Bald Eagle Management Guidelines to provide guidance to land managers, landowners, and others as to how to avoid disturbing bald eagles. For mor information, visit http://www.fws.gov/migratorybirds/baldeagle.htm Threatened due to similarity of appearance(T(S/A))_ In the November 4, 1997 Federal Register (55822-55825), the northern population of the bog turtle (from New York south to Maryland) was listed as T (threatened), and the southern population (from Virginia south to Georgia) was listed as T(S/A) (threatened due to similarity of appearance). The T(S/A) designation bans the collection and interstate and international commercial trade of bog turtles from the southern population. The T(S/A) designation has no effect on land management activities by private landowners in North Carolina, part of the southern population of the species. In addition to its official status as T(S/A), the U.S. Fish and Wildlife Service considers the southern population of the bog turtle as a Federal species of concern due to habitat loss. Definitions of Record Status: Current - the species has been observed in the county within the last 50 years. Historic - the species was last observed in the county more than 50 years ago. Obscure - the date and/or location of observation is uncertain. Incidental/migrant - the species was observed outside of its normal range or habitat. Probable/potential - the species is considered likely to occur in this county based on the proximity of known records (in adjacent counties), the presence of potentially suitable habitat, or both. USDA United States Department of Agriculture N RCS Natural Resources Conservation Service A product of the National Cooperative Soil Survey, a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local participants Custom Soil Resource Report for Swain County Area, North Carolina November 20, 2019 Preface Soil surveys contain information that affects land use planning in survey areas. They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nres.usda.gov/wps/ portal/nres/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/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, 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 areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water 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 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 classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil 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 0 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.

Soil Survey Area: Swain County Area, North Carolina Survey Area Data: Version 13, Sep 16, 2019 Soil map units are labeled (as space allows) for map scales 1:50,000 or larger. Date(s) aerial images were photographed: Feb 6, 2016—Oct 26, 2017 The orthophoto or other base map on which the soil lines were compiled and digitized probably differs from the background imagery displayed on these maps. As a result, some minor shifting of map unit boundaries may be evident. 10 Custom Soil Resource Report Map Unit Legend Map Unit Symbol Map Unit Name Acres in AOI Percent of AOI ExD Evard-Cowee-Urban land 1.0 3.1% complex, 15 to 30 percent slopes Redd ies-Del Wood complex, 0 RdA 1.1 3.2% to 3 percent slopes, occasionally flooded UfB Udorthents-Urban land 26.1 76.8% complex, 0 to 5 percent slopes, rarely flooded UrE Udorthents-Urban land 2.0 6.0% complex, 2 to 50 percent slopes W Water 3.7 10.9% Totals for Area of Interest 34.0 100.0% Map Unit Descriptions The map units delineated on the detailed soil maps in a soil survey represent the soils or miscellaneous areas in the survey area. The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not 11 Custom Soil Resource Report 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. An identifying symbol precedes the map unit name in the map unit descriptions. 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. 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 similar. Alpha -Beta association, 0 to 2 percent slopes, is an example. 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. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. 12 Custom Soil Resource Report Swain County Area, North Carolina ExD—Evard-Cowee-Urban land complex, 15 to 30 percent slopes Map Unit Setting National map unit symbol: Invx Elevation: 1,720 to 3,570 feet Mean annual precipitation: 50 to 60 inches Mean annual air temperature: 46 to 57 degrees F Frost -free period: 124 to 176 days Farmland classification: Not prime farmland Map Unit Composition Evard and similar soils: 40 percent Cowee, stony, and similar soils: 25 percent Urban land: 20 percent Minor components: 15 percent Estimates are based on observations, descriptions, and transects of the mapunit.

These percentiles provide perspective on how the selected block group or buffer area compares to the entire state, EPA region, or nation. For example, if a given location is at the 95th percentile nationwide, this means that only 5 percent of the US population has a higher block group value than the average person in the location being analyzed. The years for which the data are available, and the methods used, vary across these indicators.

EPA developed the NATA to prioritize air toxics, emission sources, and locations of interest for further study. It is important to remember that NATA provides broad estimates of health risks over geographic areas of the country, not definitive risks to specific individuals or locations. More information on the NATA analysis can be found at: https://www.epa.gov/national-air-toxics-assessment. For additional information, see: www.epa.gov/environmentaljustice EJSCREEN is a screening tool for pre -decisional use only. It can help identify areas that may warrant additional consideration, analysis, or outreach. It does not provide a basis for decision -making, but it may help identify potential areas of EJ concern. Users should keep in mind that screening tools are subject to substantial uncertainty in their demographic and environmental data, particularly when looking at small geographic areas. Important caveats and uncertainties apply to this screening -level information, so it is essential to understand the limitations on appropriate interpretations and applications of these indicators. Please see EJSCREEN documentation for discussion of these issues before using reports.

Please note that all evidence presented in support of your request for remission must be submitted in writing. The Director of the Division of Water Resources will review your evidence and inform you of his decision in the matter of your remission request. The response will provide details regarding the case status, directions for payment, and provision for further appeal of the penalty to the Environmental Management Commission's Committee on Civil Penalty Remissions (Committee).

This inspection was conducted at your request to assist in identifying the possible cause of issues at the wastewater treatment plant (WWTP) which the operators referred to as "biological die -off'. Please note that it is not possible to determine the cause of the problems with one site visit. Our goal was to assess the current overall operation of the WWTP. Based on our observations, the operators need to begin implementing a system of regular process controls to determine a baseline for how the WWTP is operating. Consistent monitoring and data reviews will help to determine any changes in influent and treatment components. Another important factor seems to be determining what changes, if any, have occurred with industrial users in the past year. The findings and comments noted during this inspection are provided in the enclosed copy of the inspection report. e:��Dff .1 North Carolina Department of Environmental Quality I Division of Water Resources 2090 US 70 Highway, Swannanoa, NC 28778 828.296.4500 DocuSign Envelope ID: 7282B5CA-5BA8-463E-9664-A7C10FE69B16 If you should have any questions, please do not hesitate to contact me with the Water Quality Regional Operations Section in the Asheville Regional Office at 828-296-4500 or via email at bev.price@ncdenr.gov.

This inspection was conducted at the request of Regina Mathis, Town Manager. Regina Mathis, Stephen Queen and Greg Passmore were present and assisted with the inspection. Inspectors were on -site to assist in trying to determine the cause of what the operators referred to as biological die -off. According to facility staff the WWTP has been re -seeded twice in 2018 and once in 2017. It is not possible to determine the cause of WWTP upsets in one site visit. It should also be noted that any change(s) in the mode of operation of the WWTP should be done at a pace to allow for results of the changes to be evaluated before additional changes are made. Facility personnel should review data on a daily, weekly and monthly basis to determine trends in changes in effluent quality. Observations of physical characteristics should be noted as well. Process control measures should be started and continued on a regular schedule. Observations and recommendations are detailed within the inspection report and the summary below. Process Controls: Monitor Dissolved Oxygen (DO) daily in the aeration zones at both WWTP's. DO was <1 mg/I in both WWTP's. Ideally, DO should be 1-3 mg/I. Additional/replacement blowers might be needed. Settable Solids Test — perform daily Mixed Liquor Suspended Solids (MLSS) Test — perform daily/weekly to determine wasting frequency pH — monitor influent and contact stabilization basin daily Monitor sludge depth in the clarifiers daily using a sludge judge Solids Removal/Bar Screen: The trailer for collecting solids needs to be repaired and emptied more frequently. All wastewater from the screening area should be routed back to the head of the WWTP. Chlorine Contact Basin: The basin contained a lot of grease and floating solids. It is recommended that the chlorine contact basin be pumped to remove solids. The FOG program should be evaluated by the collection system ORC to ensure grease traps are pumped as required. Composite Sampler: Evaluate the pump to ensure proper operation. Place a thermometer in the refrigerator box. Sampler should be set to collect flow proportional samples if not already flow proportional.

Please note that all evidence presented in support of your request for remission must be submitted in writing. The Director of the Division of Water Resources will review your evidence and inform you of his decision in the matter of your remission request. The response will provide details regarding the case status, directions for payment, and provision for further appeal of the penalty to the Environmental Management Commission's Committee on Civil Penalty Remissions (Committee).

As we have continued to experience severe rain events, we have taken the following steps to address the Inflow and Infiltration (1&I) in our system causing excessive flow through our treatment plan: 1) Maintenance crews have inspected manholes during heavy rains. Work orders have been made to address the problem areas. 2) On March 4-6, 2019, Fred Summers with NC Rural Water was invited to the Town to help with smoke testing. There were several issues identified including gutters hooked to the sanitary sewer system, drain lines hooked to sewer system, and missing caps on clganouts. Certified letters were sent to customers requiring them to correct the identified issue within 30 days. 3) During this smoke testing, the Town has identified projects to complete to help address areas with 1&I, 4) We have received $95,000 for an Asset Inventory and Assessment Grant. This funding will be used to conduct a comprehensive infiltration/inflow evaluation of our sanitary sewer collection system. The results will help the Town prioritize the areas to repair and/or replace within the sewer system which will have the most impact in reducing I&1. Flow meters, smoke testing, and video inspections of the sewer lines will be performed. Please contact me if you have additional questions concerning this response.

Box 726 Bryson City, NC 28713-0726 Subject: Imposition of Sewer Line Moratorium Demonstration of Future Wastewater Treatment Capacities NPDES Permit NCO026557 Bryson City WWTP Swain County Dear Ms. Mathis: 15A NCAC 02T .0118, "Demonstration of Future Wastewater Treatment Capacities," was adopted by the Environmental Management Commission to ensure that wastewater treatment systems owned or operated by municipalities, counties, sanitary districts or public utilities do not exceed their hydraulic treatment capacities. This Rule specifies that no permits for sewer line extensions will be issued by the Division to facilities exceeding 80% of their hydraulic treatment capacity unless specific evaluations of future wastewater treatment needs have been completed. A review of your discharge monitoring report data for the period August 2018 through July 2019 has indicated flow at the subject facility exceeded the 80% threshold. The average flow calculated for this period was 0.5251 MGD, and represented 87.5% of the current treatment capacity. Therefore, we will be unable to approve any further sewer line extensions for this facility until such time as you have complied with the requirements contained in the Rule. In order to attain compliance with the Rule, you must submit an approvable engineering evaluation of future wastewater treatment needs. This evaluation must outline specific plans for system expansion and include the sources of funding for the expansion. If future expansion is not proposed, a detailed justification must be made based on past growth records and future growth projections and, as appropriate, shall include conservation plans or other specific measures to achieve waste flow reductions.

The Town acknowledges the evidence of average flows exceeding 80% of its wastewater treatment plant capacity as provided in 15A NCAC 02T.0118, "Demonstration of Future Wastewater Treatment Capacities." The Town is in the process of compliance with this rule by completing the two engineering studies outlined below: 1. Wastewater Treatment Plant Alternatives Analysis This study is funded by a Special Evaluation Assistance for Rural Communities and Households (SEARCH) grant from Rural Development (RD). The study will evaluate alternatives to renovate expand and/or replace the Town's existing WWTP. The study will also project future flows on which to base WWTP capacity decisions. The Town anticipates this study being completed in early 2020, 2. Asset Inventory Analysis This HomeTown Strong funded initiative will conduct an infiltration/inflow (1/1) analysis to identify areas of the Town's system which are susceptible to stormwater and groundwater intrusion. The results of the study are expected to identify capital projects which will reduce 1/1 to acceptable levels, restoring flow capacity to the system for future growth. The Town anticipates this study being completed in early 2020. The Town has approved the following connections to its' sewer system, prior to receiving the moratorium letter: • 10 residential taps with a total of 20 bedrooms @ 120 gpd/bedroom = 2,400 gpd 4 small townhomes with 1 bedroom each @ 120 gpd/bedroom = 480 gpd • 17 vacation cottages @ 200 gallons/unit = 3,400 gpd • Art gallery with 2 restrooms @ 125 gallons per fixture = 250 gpd • 60-room hotel @ 120 gallons/room = 7,200 gpd Total: 13,730 gpd MCGILL ASSOCIATES 55 BROAD STREET, ASHEVILLE, NC 28801 / 828.252.0575 / MCGILLASSOCIATES.COM Mr. Charles Weaver November 13, 2019 Page 2 of 2 The Town believes that the addition of this flow, which will occur gradually over the next 12 months, will not adversely impact the existing WWTP's ability to comply with its NPDES Permit. Further, they will work closely with Tim Heim of the NCDEQ Asheville Regional Office in communicating the recommendations resulting from the aforementioned studies and other capital upgrades planned for its wastewater system.

Wf Town of Bryson City Annual Performance Report I. General Information Facility System Name: Town of Bryson City 315 Riverview Drive Swain County Permit Wastewater Treatment: NC0026557 Collections Permit: WQCS00170 Person in Charge: Wastewater Plant ORC-Environmental, Inc. Collection System ORC-Tom Shook Description of System: Bryson City operates a 0.6 MGD wastewater treatment facility located at 315 Riverview Road southwest of Bryson City in Swain County. The treatment components include: mechanical bar screen, two contact stabilization treatment units consisting of influent pumping, reaeration zones, secondary clarifiers, sludge digester, belt press, sludge dry storage, chlorination, and dechlorination. Discharge from the treatment enters into the Tuckasegee River, a class B water within the Little Tennessee River Basin. The Town operates a sanitary sewer system composed of gravity sewer lines, constructed of various materials, including vitrified clay, PVC and ductile iron. Seven lift stations are presently operating within the collection system. II Notice of Violations: Summary of System Performance from July 1, 2018 to June 30, 2019 July 2018 Notice of violation and intent to assess civil penalty for violations on 7/5/18 and 7/31/18 at the wastewater treatment plant (WWTP) for exceeding the daily maximum for coliform, fecal. At the time of the violation on 7/5/18, the WWTP was operating with only one tank rather than two. Tank 92 had been down for approximately 6-8 weeks due to a blown motor and gearbox on the skimmer. The company had originally sent a single-phase motor rather than a three phase. Both tanks were back operational on July 4, 2018. It was also during the time that there was an issue with the chemical feed pump so the discharge was not getting chlorinated like it should. The problem was fixed. A permit violation on 7/31/18 for failure to maintain "Operator Arrival Time" & "Operator Time on Site" at the wastewater treatment plant. The ORC had to resubmit the report for 7/31/18. He had forgotten to include the "Operator Arrival Time" and "Operator Time on Site." August 2018 Notice of violation on 8/1/18 due to Sanitary Sewer Overflow (SSO) of the manhole located at 45 Everett Street. December 2018 Notice of violation and intent to access civil penalty for violation on 12/28/18 due to Sanitary Sewer Overflow (SSO) at the manhole located at 45 Everett Street. Maintenance crews have inspected manholes during heavy rains and work orders have been placed to address some of the problem areas. We are W reviewing ordinances and will include one requiring campgrounds near the river to have spring loaded sewer caps that close automatically when campers hastily unhook campers from the sewer system without placing the sewer cap on the sewer pipe. February 2019 Notice of violation and intent to access civil penalty for violation on 2/12/19 for Sanitary Sewer Overflow (SSO) at the manhole located at 45 Everett St. On March 4-6, 2019 smoke testing was performed at a section of town. There were several issues identified including gutters hooked to the sanitary sewer system, drain lines hooked to the sewer system, and missing caps on cleanouts. Certified letters were sent to customers requiring them to correct the identified issue. Notice of violation for exceeding the monthly average flow at the wastewater treatment plant. This was due to several heavy rainfalls. March 2019 Notice of violation and intent to assess civil penalty for violation on March 31, 2019 for exceeding the monthly average flow at the wastewater treatment plant. III.

ELECTRONIC REPORTING OF MONITORING REPORTS [G.S. 143-215.1(b)] Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program reports. The final NPDES Electronic Reporting Rule was adopted and became effective on December 21, 2015. NOTE This special condition supplements or supersedes the following sections within Part 11 of this permit (Standard Conditions for NPDES Permits): • Section B. (11.) Signatory Requirements • Section D (2.) • Section D (6.) • Section E. (5.) Reporting Records Retention Monitoring Reports 1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)1 The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) mternet application. Monitoring results obtained during the previous month(s) shall be summarized for each month and submitted electronically using eDMR. The eDMR system allows permitted facilities to enter monitoring data and submit DMRs electronically using the internet Until such time that the state's eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation (CROMERR), permittees will be required to submit all discharge monitoring data to the state electronically using eDMR and will be required to complete the eDMR submission by printing, signing, and submitting one signed original and a copy of the computer printed eDMR to the following address: NC DEQ / Division of Water Resources / Water Quality Penmttmg Section ATTENTION• Central Files 1617 Mail Service Center Raleigh, North Carolina 27699-1617 If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility being physically located in an area where less than 10 percent of the households have broadband access, then a temporary waiver from the NPDES electronic reporting requirements may be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1. 1, 2, 3) or alternative forms approved by the Director. Duplicate signed copies shall be submitted to the mailing address above. See "How to Request a Waiver from Electronic Reporting" section below. Regardless of the submission method, the first DMR is due on the last day of the month following the issuance of the permit or in the case of a new facility, on the last day of the month following the commencement of discharge. Starting on December 21, 2020, the permittee must electronically report the following compliance monitoring data and reports, when applicable: Sewer Overflow/Bypass Event Reports; Pretreatment Program Annual Reports; and Clean Water Act (CWA) Section 316(b) Annual Reports. The permittee may seek an electronic reporting waiver from the Division (see "How to Request a Waiver from Electronic Reporting" section below). Page 4 of 6 NPDES Permit NC0026557 2. Electronic Submissions In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the time of each electronic submission. The permittee should use the EPA's website resources to identify the initial recipient for the electronic submission. Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity (EPA or the state authorized by EPA to implement the NPDES program) that is the designated entity for receiving electronic NPDES data [see 40 CFR 127.2(b)]. EPA plans to establish a website that will also link to the appropriate electronic reporting tool for each type of electronic submission and for each state. Instructions on how to access and use the appropriate electronic reporting tool will be available as well. Information on EPA's NPDES Electronic Reporting Rule is found at: http•//www2 epa ovg /compliance/final-national-pollutant-discharge-elimination-system-npdes-electromc- reporting-rule. Electronic submissions must start by the dates listed in the "Reporting Requirements" section above. 3. How to Request a Waiver from Electronic Reporting The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an electronic reporting waiver, a perimttee must first submit an electronic reporting waiver request to the Division. Requests for temporary electronic reporting waivers must be submitted in writing to the Division for written approval at least sixty (60) days prior to the date the facility would be required under this permit to begin submitting monitoring data and reports The duration of a temporary waiver shall not exceed 5 years and shall thereupon expire At such time, monitoring data and reports shall be submitted electronically to the Division unless the permittee re -applies for and is granted a new temporary electronic reporting waiver by the Division. Approved electronic reporting waivers are not transferrable. Only permittees with an approved reporting waiver request may submit monitoring data and reports on paper to the Division for the period that the approved reporting waiver request is effective.

APPENDIX 8: I/I REMEDIATION PROJECT LIST INFLOW / INFILTRATION REMEDIATION PROJECT LIST UPDATE 3/31/2020 TOWN OF BRYSON CITY, NC Shaping Communities Together This document is generated as a result of the Town's 2019/2020 Asset Inventory and Assessment project funded by NCDEQ, which is currently underway. Significant sources of inflow and infiltration have been identified herein. Each project is accompanied by a short description, location map, and estimation of probable cost. It is intended that this supplement is used to obtain funding in addition to that which is intended for improvement of the Town's wastewater treatment facility. It will ultimately be merged with the final AIA project deliverable. Attached to this document, in no particular order, is a list of several small-scale projects that are categorized as immediate needs to combat inflow and infiltration but are not of a sufficient size to warrant outside funding as major capital improvements. This list has been provided to Town staff and they have begun the process of addressing the areas identified. We would like to acknowledge the field crew members for their enthusiasm in repairing these problem areas.

The project area begins at manhole #53 and extends to manhole #69. These line segments consist of antiquated VCP and concrete pipes. The line sections are generally in poor condition as identified by qualitive observation and limited CCTV inspection. Manholes are in poor condition as well. Many are brick with suspect penetrations and poor inverts. Significant surcharging has been observed. Inflow and infiltration along this line is notable. Smoke testing of some of these line segments revealed connections to stormwater catch basins and/or pipes. Flow testing was also performed at manhole #57, monitoring the basin to the east encompassing Island Street, Ramseur Street, Deep Creek Road and various side streets. Average dry weather flows of 55 gpm were noted. During rain events flows exceeding 250 gpm were recorded with a peaking factor of 4.5 times that of average dry weather flow. -22 2• L 22-- 22 r 2" I 2+P► 22= - L22 v 2..
