One set of requirements for flows below 0.5 MGD, and another more stringent set of requirements for flows from 0.5 to 0.9 MGD. The Town is required to send a letter to the Asheville Regional Office of the NCDEQ after any month the average flow is 0.4 MGD or greater. In December 2018 the Old Fort WWTP averaged 0.459 MGD due to heavy rains and high inflow and infiltration. The Town would like to remain under the 0.5 MGD monitoring schedule, as we feel this is an unusual occurrence and the Town is looking to resolve some of inflow & infiltration issues. The Town is also completing an Asset Inventory and Capital Improvement Plan, which has several parts of the wastewater collection system scheduled for repair and replacement. We feel that once these repairs are completed, it will reduce the amount of 1/1 the WWTP receives. And because the plant is at less than 25% of capacity, it has had no permit limit violations. The Town is continuing to work to improve this situation in the collection system and at the WWTP.

This Report describes how the utility will manage these infrastructure assets. The WWTP has a design capacity of 0.5 MGD and currently manages an average of 0.164 MGD. Based on projected McDowell County population growth, wastewater flow in Old Fort is projected to increase to approximately 170,700 gpd average by 2037; still way below the WWTP's permitted capacity. See Tables 2.2 and 2.3. The following items summarize the utility s asset review and plan to provide for long-term improvements in the operation and maintenance of the sanitary sewer system and WWTP: ■ Table 4.1 contains an inventory of treatment train components at the Old Fort Wastewater Treatment Plant (WWTP). The table also contains an assessment of each component including age, condition, consequence of failure, replacement year, risk factor category, and action based on risk., Table 6.1 establishes the proposed improvements at the WWTP. ® Several sections of the existing sanitary sewer system were selected by the Town to be video inspected as part of the sewer system assessment. A copy of the resulting Video Inspection Report is included in Appendix B. Table 6.2 is a condition assessment of those videoed sewer lines. • It is estimated that the utility will spend between $42,000 and $52,500 per year for the next 10 years for sewer system rehabilitation projects out of fund balance. A financial summary for the annual expenditures for sewer system improvements is presented in Table 6.3. Table 6.4 provides the projected expenditures for both WWTP and sewer system expenditures by fiscal year including anticipated rate increases needed to fund the WWTP improvements, assuming loans will be acquired for the WWTP improvements. ® Table 6.5 presents the Total Projected Expenditures for the Water and Sewer Department, proposed utilization of reserve funds and anticipated sewer rate increases over the 10-year CIP. By contributing $104,000 in FY 2019-2020 and 100,000 in FY 2020-2021 from reserves to the Water and Sewer Budget, the Town may be able to keep its sewer rates at their current level. The major improvements at the wastewater treatment plant are proposed to be funded through a State Revolving Loan in FY2024-2025. The annual debt service for these improvements, assuming 2.25% interest rate and a 20-year term, has been included in the Sewer System CIP beginning in FY 2024-2025. It is expected that it will not be necessary to increase sewer rates through the 10-year term of the CIP. See Table 6.5. ■ The operating ratio will be greater than or equal to 1.0 during the next 10 years. 4 1 November 2018 Old Fort 2018 Wastewater Asset Inventory and Assessment Report 1. INTRODUCTION This Asset Inventory and Assessment Report covers the Town of Old Fort's Wastewater Treatment Plant and sanitary sewer system. Customer service demands and regulations require utilities to actively manage water and wastewater assets through careful maintenance, repair and replacement decisions.

LEVEL OF SERVICE AGREEMENT The goal of the Town of Old Fort Wastewater Treatment Plant is to confirm wastewater is treated effectively and efficiently by providing services that meet or exceed customer expectations and comply with federal, state, and local regulations. This section describes both utilities' Level of Service goals and the key performance targets for each Level of Service goal for present and future performance. The Level of Service describes the characteristics of the utility's performance, such as "how much", "of what nature", and "how frequently." The utility's progress toward meeting those goals will be reviewed annually. The Levels of Service determine the amount of funding that is required to maintain, renew and upgrade the entire wastewater collection and treatment infrastructure to provide the customers with the Levels of Service specified. The Level of Service goals are defined across the four service areas identified below. Changes to the Levels of Service goals and how the utility addresses the issues will affect funding requirements and how well the utility can provide the proper service to the community. The Target Levels of Service that the utility has chosen to meet are presented in Table 3.1. This table lists the Level of Service goals and measures the success of each goal. Table 3.1. Level of Service Goals Health, Safety, and Comply with all federal, state, and Meets all performance objectives Security local worker safety requirements Asset Preservation and Perform routine maintenance on all Condition major equipment per factory Meets all performance objectives recommendations Conservation, Compliance, Meet all federal, state, and local Meets all performance objectives and Enhancement regulatory standards Provide uninterrupted service for the Wastewater Treatment Plant and Meets all performance objectives Service Quality and Cost sanitary sewer service areas Sewer rates reviewed annually Meets all performance objectives C 9 ]November 2018 Old Fort 2018 Wastewater Asset Inventory and Assessment Report 4. INVENTORY OF CRITICAL ASSETS The Town of Old Fort Wastewater Treatment Plant and Sanitary Sewer System include assets associated with the sanitary sewer system, lift stations, the treatment process and maintenance of treatment facilities. A map of the collection system is provided in Figure 4-1. Figure 4-2 includes blowup maps of individual sanitary sewer system that were prepared as part of the AIA Project. A schematic of the Wastewater Treatment Plant process flow identifying the major unit processes is provided in Figure 4-3. Figure 4-4 is a map of the sewer lines that were video inspected. Some assets are more important than others in making sure that wastewater is collected and treated effectively. Therefore, the Asset Inventory and Assessment team used the CUPSS software (developed by the U.S. Environmental Protection Agency) to identify and prioritize critical assets. This process includes reviewing all assets and recording their conditions (likelihood of failure), criticality to the utility (consequence of failure) and redundancy (the number of back-up assets to help support each asset). The information collected during the review is used to assign a risk to each asset. This will ensure that the utility delivers the level of service described in the previous section. The following sections define the metrics used to assess each asset: Condition The condition of each of the critical assets was ranked according to the following scale: a Excellent -New equipment with >:90% of anticipated equipment life remaining IN Good -Equipment with <90% of anticipated equipment life remaining and in above average condition It Fair -Average condition and suitable for operation a Poor -Not suitable for long-term use due to offset joints, significant corrosion, cracks, reduced capacity, or other mechanical or electrical deficiencies a Very Poor -Not operable Assets rated as poor or very poor are addressed through the capital improvement plan. Consequence of Failure As defined in the CUPSS guidance, consequence of failure "estimates the degree of impact on utility service should the asset fail''. The consequence of failure of each asset was ranked according to the following scale: ® Insignificant - Minimal short-term or long-term impact on wastewater conveyance or treatment operations ® Minor - Minimal short-term impact on wastewater conveyance or treatment operations a Moderate - Operations will be disrupted, but may not impact compliance a Major - Wastewater conveyance or treatment will be severely disrupted, service to customers may be disrupted, and noncompliance is probable a Catastrophic - The Wastewater Treatment Plant may shutdown, service to customers may be halted, or there may be a water quality emergency. Redundancy a The redundancy of each asset was recorded as one of the following categories: a 0% Back-up 0 50% Back-up ■ 100% Back-up a 200% Secondary Back-up. ' CUPSS Release 1.3.10, July 2017, User's Guide. November 2018 Old Fort 2018 Wastewater Asset Inventory and Assessment Report Risk Category As defined in the CUPSS guidance, the risk category identifies the "potential for realization of unwanted adverse consequences or events"2 associated with the condition or performance of a specific asset. Risks were categorized as: • High -Provide immediate attention to monitor asset condition and develop plans for asset repair, rehabilitation, or replacement s Medium - Provide aggressive monitoring o Low -Perform routine maintenance for asset to extend remaining useful life. The risk category was assigned based on the probability of failure and the consequence of failure. The probability of failure was estimated based on the remaining useful life of the equipment and the redundancy provided for the equipment. Appendix A provides a summary of the risk calculation. The Town of Old Fort Wastewater Treatment Plant and the Old Fort Public Works Asset Inventory and Assessment Team has completed the asset assessment. The assessment of the equipment and components at the wastewater treatment plant is based on operator knowledge, age and type of equipment, and observed equipment performance. The assessment of the sanitary sewer conditions is based on the result of the sewer video work performed on certain portions of the sanitary sewer system. Table 4.1 lists assets at the wastewater treatment plant and identifies those that are critical to maintain the performance of the plant. Table 6.2 lists the results of the sanitary sewer video inspection report and the actual viewing of the sewer videos, themselves. The sewer video inspection report is included in Appendix B. 2 2 CUPSS Release 1.3.10, July 2017, User's Guide. 111 November 2018 Old Fort 2018 Wastewater Asset Inventory and Assessment Report Laboratory/Operations Building HVAC System Influent Pump No. 1 Influent Pump No. 2 Pump No.3 Pump Station Building Influent Pump Power Panel Automated Influent Sampler Automated Effluent Sampler Mechanical Bar Screen Bar Screen Control Panel Bar Screen Power Panel Vortex Grit Chamber EQ Basin Concrete EQ Basin Blower 1 EQ Basin Blower 2 EQ Basin Blower 3 I LEQ Basin Diffusers and Air Piping EQ Basin Effluent Pump 1 EQ Basin Effluent Pump 2 Aeration Basin 1 Concrete 3Aeration Basin 1 Floating Aerator 1 O Aeration Basin 1 Floating Aerator 2 Aeration Basin 1 Floating Aerator 3 • Aeration Basin 1 Aerator Power Panel Aeration Basin 2 Concrete Aeration Basin 2 Floating Aerator 1 0 Aeration Basin 2 Floating Aerator 20 Aeration Basin 2 Floating Aerator 3 Aeration Basin 2 Aerator Power Panel Aeration Basins Influent Splitter Box 0 Aeration Basin Splitter Box Gates O Clarifier No.1 Clarifier No. l Concrete Clarifier No. 2 Clarifier No. 2 Concrete Clarifier No.3 - ..._:.:__..�,, 2C1v 1Tank Operation Building Operation Building Influent Pump Station Influent Pump Station Influent Pump Station Influent Pump Station Influent Pump Station Lab/monitoring Lab/monitoring Influent Screening Influent Screening Influent Screening Influent Screening Flow Equalization Flow Equalization Flow Equalization Flow Equalization Flow Equalization Flow Equalization Flow Equalization Aeration Basin 1 Aeration Basin 1 Aeration Basin 1 Aeration Basin 1 Aeration Basin 1 Aeration Basin 2 Aeration Basin 2 Aeration Basin 2 Aeration Basin 2 Aeration Basin 2 Aeration Basins Aeration Basins Secondary clarifier Secondary clarifier Secondary clarifier Secondary clarifier Secondary clarifier Secondary clarifier Active Active Active Active Active Active Actived Active Active Active Active Active Active Active Active Active Active Active Rarely Used Rarely Used Active Active Active Active.

The maintenance strategy focuses on the three areas listed below and will be revisited every year. The current 0&M plan is included in Appendix E. 5.1 PREVENTIVE MAINTENANCE Preventive maintenance is the day-to-day work necessary to keep assets operating properly, which includes the following: 1. Regular and ongoing annual tasks necessary to keep the assets at their required service level 2. Day-to-day and general upkeep designed to keep the assets operating at the required levels of service 3. Tasks that provide for the normal care and attention of the asset including repairs and minor replacements Preventive maintenance is carried out because of a planned maintenance program (such as regularly scheduled asset repairs) and historically problematic operations. Equipment must be maintained according to manufacturer's recommendations to achieve maximum return on investment. By simply following the manufacturer's suggested preventive maintenance the useful life of equipment can be increased 2 to 3 times when compared to run till failure. Communities that have eliminated preventive maintenance practices from their operating budget can achieve positive returns from a relatively small additional investment. 5.2 EMERGENCY/REACTIVE MAINTENANCE Reactive maintenance is often carried out because of customer requests or sudden asset failures. The required service and maintenance to fix the customers issue(s) is identified by staff inspection. 5.3 DEFERRED MAINTENANCE Deferred maintenance is any maintenance, repair, restoration or replacement work that should have been accomplished before now, and that has not been performed. The utility plans to reduce overall deferred maintenance over the following 10 years by implementing the capital improvement plan. 14 1 November 2018 Old Fart2018 Wastewater Asset Inventory and Assessment Report 6. CAPITAL IMPROVEMENT PLAN (CIP) The Town of Old Fort Wastewater Treatment Plant capital improvement plan (Wastewater Treatment Plant CIP), the Sanitary Sewer System Capital Improvement Plan and the Water Plant Capital improvement plan (WTP CIP included in the Water AIA Report) provide the description of future capital project needs for the next 10. years. Capital improvement projects generally create a new asset that previously did not exist or they upgrade and improve an existing asset's capacity or capability to better perform. The projects noted in the CIP can result from growth or environmental needs, such as the following: a Expenditure that purchases or creates a new asset or in any way improves an asset beyond its original design capacity a Upgrades that increase the capacity of the asset Construction designed to produce an improvement in the standard operation of the asset beyond its present capacity or beyond its present operational performance. In addition to capital improvement projects, the Asset Inventory and Assessment team has reviewed and is -- -- - establishing a renewal (or rehabilitation) strategy. Renewal expenditure is anything that does not increase the asset's design capacity but restores an existing asset to its original capacity. Any improvement projects that require more than simply restoring an asset to its original capacity are deemed to be a renewal project, such as the following: • Activities that do not increase the capacity of the asset (i.e., upgrade and enhance the assets, restoring them to their original size, condition, and capacity) • Rehabilitation involving improvements and realignment or restores the assets to a new or fresh condition. In making renewal decisions, the utility considered several categories other than the normally recognized physical, failure or breakage. Such renewal decisions include the following: a Structural • Capacity s Level of service failures ■ Outdated functionality • Cost or economic impact. Summaries of the current plans are presented in Table 6.1 and Table 6.2. Because the expected needs of the utility will change each year, the CIP plan will be updated to reflect those changes. 6.1 FINANCIAL MANAGEMENT STRATEGY This section describes the Town of Old Fort Utilities Department financial condition and its strategy for future financing. Equipment expenses greater than or equal to $200 are considered capital costs. Capital costs are one- time expenses (not including labor) used to replace or upgrade, because of capacity, a part of the utility's infrastructure. Capital costs do not include 0&M costs. Collection system, wastewater treatment, water treatment and distribution system expenses are funded through grants, loans and general rates and fees. The Town of Old Fort received funding for the Wastewater Treatment Plant Improvement Project from the Clean Water Revolving Fund. This project included replacement of the anaerobic basin mixers, aerobic digester sludge recirculation pumps, and installation of new aerobic digester air jammers. The Town has retired the existing debt service for the Wastewater Treatment Plant. The budgetary savings due to this debt retirement are being transferred to the Town's Wastewater Treatment Plant Capital Reserve for use on future projects. Therefore, it is assumed that the WWTP capital projects that are being proposed herein will be funded by the Capital Reserve and/or potential State and Federal grant/loan programs. The utility estimates that it will spend a total of $0.8M on wastewater over the next 10 years to upgrade the Wastewater Treatment 15 Ortnhcr 201 A nm Pnrt 9m A Plant equipment so that it can continue to maintain compliance with state, and federal effluent limits. A financial summary noting the planned improvements at the wastewater treatment plan for the next 10 years is presented in Table 6.1. The utility estimates that it will spend a total of $0.6M on sanitary sewer system improvements over the next 10 years to rehabilitate or replace old terra cotta pipe and brick manholes. A financial summary for the next 10 years is presented in Table 6-4. 6.1.1 Total Expenditures Table 6.5 illustrates the forecasted financial needs for the next 10 years. The financial forecast includes the capital cost for Wastewater Treatment Plant improvement projects and sanitary sewer system projects that are recommended to be completed in the next 10 years. 6.2 USER RATES Fee increases are not required at this time to implement the first year in the CIP and to maintain an operating ratio greater than or equal to 1 in the first year. 16 October 2018 Old Fort 2018 Wastewater Asset Inventory and Assessment Report Table 6.1.

Debt service for $885,500 for 20 years at 2.75% = approximately $50,000/year. Assumes State Revolving Loan Funds. 4 The Town of Old Fort is in the process of replacing the Belt Press Control Panel and having it wired. It was funded in the 2017-2018 FY budget and so will not be included in the CIP overall costs when calculating rate increases. S The Estimated Total Project Cost is distributed over the life of the project (up to 20 years) and includes project costs (excluding debt service) covered by grants, loans. The Town of Old Fort costs associated with a project may be distributed in fiscal years after 2029 and that distribution is not presented in this table. 17 NovemberSG18 Old Fort 2018 Wastewater Asset Inventory and Assessment Report 6.2 Videcied Sewer Lines Condition RecommendationsTable Assessments and Work Segment us DS Pipe e Dia.

USER RATE CALCULATIONS The Town charges sewer customers a sewer consumption fee based on the total volume of water used. Out of town customers are billed at a higher consumption rate than in -town customers. The current sewer use fees are shown in Table 7-1. The current water user fees are shown in Table 7-2. Table 7.1. Current Sewer User Fees Residential/Commercial - In Town $6.00 $4.39 Residential/Commercial — Out of Town $6.00 $8.78 Industries — Up to 100,000 Gal/Month $6.00 $4.39 Industries — Usage above 100,000 Gal/Mo $4.00 Notes: 1. Minimum monthly charge is for all customers regardless of usage. 2. $/1000 gallons up to 100,000 gallons per month. $4.00/1000 gallons for all usage over 100,000 gal/month Table 7.2. Current Water User Fees Residential/Commercial - In Town $6.00 $3.47 Residential/Commercial—Out of Town $6.00 $6.93 Industries — Up to 100,000 Gal/Month $6.00 $3.47 Industries — Usage above 100,000 Gal/Mo $3.20 Notes: 1. Minimum monthly charge is for all customers regardless of usage. 2. $/1000 gallons up to 100,000 gallons per month. $3.20/1000 gallons for all usage over 100,000 gal/month The current water and sewer user fees, plus usage of current Water and Sewer Department Reserve Funds in Fiscal Years 2019 through 2021, provide for implementation of the CIP. The Town will maintain the current rate structure to build capital reserve for future Wastewater Treatment Plant improvement and for sewer system improvements projects. Sewer rate increases (%/year) are noted in Table 6.5. It is proposed to fund the sewer system improvements through contributions to the Capital Improvements Plan from Water and Sewer Department Reserve Funds. However, some of the proposed wastewater treatment plant improvements are needed beginning FY 2019- 2020. It is proposed to finance those improvements through the State Revolving Loan Funds in FY 2024-2025 in order to refrain from raising the sewer rates drastically at one time. 23 1 November 2018 Old Fort 2018 Wastewater Asset Inventory and Assessment Report 8. RECOMMENDATIONS The Town of Old Fort Wastewater Treatment Plant and Sewer Lines Asset Inventory and Assessment Report refers to many objectives, targets, and improvements for the utility. It is recommended that the Town of Old Fort consider the following to successfully implement the Asset Inventory and Assessment Plan: • Review this plan annually and update the community on new information and revisions ® Implement the 0&M plan to extend the life of equipment a Pursue funding for the projects identified in the Tables 6.1 and 6.3.

Additionally, through the use of a GIS software program, the Town can look at individual attributes of the sewer system, such as manhole depths, pipe types, etc. f. Legal Authorities and Controls 1. Sewer Use Ordinance The Town of Old Fort has established and implemented regulations regarding the use of the wastewater collection system. Old Fort has a sewer use ordinance, consistent with EPA's model ordinance, in place. As regulations and requirements change, the Town of Old Fort passes new or additional ordinances to address those issues. Ordinances are kept up-to-date and are available at the Town Hall.. The Town of Old Fort reviews the adequacy of user rates when the Fiscal Year Budget is prepared. 2. GENERAL INFORMATION ABOUT THE TOWN OF OLD FORT'S SANITARY SEWER SYSTEM a. Wastewater Treatment and Collection System Description The Town of Old Fort's first formal wastewater collection system dates back to early 20a' century and the first wastewater treatment facility was constructed in 1967. The collection system transports wastewater to the treatment facility, located on Curtis Creek, a tributary of the Catawba River. The oldest part of the system is the downtown area, which also has the highest density of commercial customers. In 1967, the local textile plants constructed a treatment facility to treat the wastewater from the plant and from the Town. Since the closing of the textile plant in the 1980's, Town of Old Fort has operated a 0.9 mgd secondary treatment facility that provides wastewater treatment for the Town, itself, and the remaining industrial water users. The last major upgrade of the wastewater treatment facility was completed in 2004 and included new clarifier, sludge pasteurization system and new primary treatment facilities. The treated wastewater is discharged to Curtis Creek. The Town of Old Fort does not own or maintain any portion of the sewer laterals that drain each privately owned parcel or property beyond the property line. However, the Town does work with homeowners to prevent backups into their homes. The Town of Old Fort's staff and contractors perform planned maintenance tasks at scheduled frequencies. Frequencies are established based on experience and collection system information to minimize the risk of blockages or equipment failures that could lead to sewer. Approximately 10% of the sewer collection system is cleaned each year. Some portions of the wastewater collection system are maintained more frequently than others based upon past history and their importance to the effective operation of the wastewater collection system. Staff and/or contractors also perform unplanned maintenance. As part of the 2018 Sewer system Asset Inventory and Assessment Study, many of the older sewer lines were videoed. Subsequent to that video work, a Capital Improvement Plan was prepared that set forth a 10-year sewer replacement program, beginning with the 2019-2020 fiscal year. b.

E System Map Maps of the sanitary sewer system are included in the 2018 Wastewater Asset Inventory and Assessment Report to which this O&M Plan is attached. The map is current through November 1, 2018. 10 3. CLEANING, INSPECTION AND ASSESSMENT PROGRAM In 2018, the Town of Old Fort completed its Wastewater System Asset Inventory and Assessment (AIA) Study to assess the maintenance needs and structural condition of the entire collection system. During this process, the Town cleaned and video inspected approximately 5,800 LF of sanitary sewer lines, in various locations within the overall sanitary sewer system. The lines videoed were selected by the Town as suspected vitrified clay pipe or lines where problems were known to exist. The Town of Old Fort began the cleaning, inspection and assessment program with a focus on the known problem areas and the older sections of the Town. The results from the cleaning, inspection and assessment program have been used to categorize the cleaning frequency and the repair or replacement needs for each section of line. Previous knowledge of the condition of the sewer system, and the new knowledge gained from the video inspection, is being used to establish more frequent cleaning scheduled for identified problem areas. Critical infrastructure components at the wastewater treatment plant were also identified and assessed. These components have been identified in the Wastewater AIA Study, as well. The cleaning efforts are generally performed by Water and Sewer Department staff and/or by outside contractors, as was the case in the 2018 video inspection work. Data obtained from the 2018 video work has been entered in the 2018 Wastewater AIA Study. As an on -going effort, the Town will continue to clean at least 10% of its sanitary sewer system annually. During these cleaning events, the Town will take note of the manhole condition and the types of pipe entering and leaving each manhole. Such investigations will provide the Town with information regarding the expected condition of specific line segments. With that knowledge, the Town can prioritize additional future video investigations. The cleaning and CCTV schedules are closely coordinated. As the Town of Old Fort's goal is to have a complete cleaning, inspection and system assessment at least every 10 years, approximately 10% percent of the system is reviewed by CCTV each decade. Approximately 10% percent of the system is cleaned annually: the cleaning performed each year includes the priority cleaning plus 10 percent of the remaining parts of the collection system, factoring in the intermediate and long term interval cleaning schedules. All of the system cleaning is for gravity lines, as described in more detail in Section b, below. Information from cleaning and inspections (see Inspection section, below), including any findings, is entered into field logs and is noted and incorporated into the schedule for maintenance and capital improvement. This information is also used to update Asset Inventory and Assessment Study. a. Cleaning The Town's primary sewer maintenance activity is sewer line cleaning. The Town's sanitary sewer service area is divided into several sewer shed areas as contained on the Town's GIS sewer system map. 11 The cleaning of sewer lines, manholes is categorized as: priority (annual or more frequent cleaning); intermediate (2-5 year interval); or long term (6 or more year interval). Cleaning Schedules — Priority Cleaning Pipe -sections on a priority cleaning frequency are identified based on known Trouble Spots and Critical Service Areas lists. The Trouble Spots have a history of blockages or overflows. The Critical Service Areas locations where sewer malfunction would lead to major disruption, are inspected and maintained at greater frequency due to the importance of their function. Cleaning - Gravity Lines Routine Cleaning This section details schedules for the routine cleaning of each sub -area of the collection system. During the 2018 Asset Inventory and Assessment Study, each pipe and manhole was evaluated, based on MA inspection, to determine cleaning frequency. As the AIA program continues, a pole camera may be used to evaluate each sewer line to determine theneedfor cleaning and/or a CCTV structural inspection. A pipe section that has not been cleaned in over 6 years, but has been evaluated using the pole camera and shown that cleaning is not warranted, is assigned to the long term cleaning frequency (10+ years). If the camera evaluation indicates a need for cleaning, the pipe section can be put on the intermediate cleaning frequency. The cleaning schedules for other pipe sections in the sub -area will determine whether the cleaning frequency will be closer to 2-3 years or 10 years. All cleaning records are kept in a spreadsheet that tracks the following: • date, time and location of cleaning activity, • specific lines cleaned; • equipment used; • identity of cleaning crew; • number of passes needed to clean the line; • presence of root, grease, or debris; and • problems identified or other follow up actions necessary. Each line segment cleaned is identified by an upstream and downstream manhole number. A log is submitted for each day of work completed. Support from private commercial sewer cleaning and video inspection firms may also be used for cleaning and repairs, and for emergencies during non -business hours. Manhole deficiencies are also noted in cleaning logs. Information about manholes requiring attention is provided to the Water and Sewer Department Directror and either a repair work order is issued or it is added to the capital repair schedule. b. Pipe and Manhole Inspection Planned manhole and pipe inspections are coordinated with the cleaning program and generally follow the cleaning schedule. The cleaning, inspection and assessment program goal is to inspect the entire collection system within 10 years. During the 2018 AIA Study, the full CCTV screening assessed the pipe and manhole structural condition or other deficiencies. In moving forward, future video inspection should look at the following pipe conditions: C 12 • the structural condition of the pipe • root intrusion • grease • protruding taps • evidence of inflow and infiltration (UI) or surcharging • manhole pave-overs, and • other deficiencies that factor into condition assessment All newly constructed sewer lines and manholes are required to be vacuum tested to ensure tightness and prevent release of sewer odors and future infiltration of storm water. Manhole inspections help keep the asset inventory up to date and are used not only to update collection system maps, but to determine structural condition. During manhole inspections, field crews may take a complete inventory of each manhole including construction materials, ring size, depth to invert, flow conditions and evidence of problems according to the checklist in Manhole inspection results are reviewed for condition rating. Those needing repair may be placed on a priority schedule, and routine repairs are coordinated with re -paving work. Outside firms that specialize in manhole rehabilitation are generally engaged for completing structural repairs to manholes. Repairs include invert work, frame and cover grade adjustment, and frame and cover replacement.Work is completed based on priority as noted on work orders which are tracked and completed in our work order database. c. Assessment While routine cleaning and visual inspection are used to assess the condition of manholes and surface facilities, occasional CCTV video inspections are the primary method used to assess the condition of the sewer pipes. All records are entered into spreadsheets and maintained at the Town Hall. The results from routine inspection and monitoring are used to prioritize areas needing CCTV inspections to assess pipe condition such as manholes with evidence of slow flow or surcharging. The assessment is logged into Sewer Inspection Worksheets using conventional defect criteria. In 2018, approximately 103.1 LF of 6" pipe, 3,861.6 LF of 8" pipe and 2,246.7 of 12" pipe were video inspected and a rehabilitation plan prepared. The digital videos have been reviewed and condition assessments entered into the Town's 10-Year Capital Improvement Plan. Pipe condition information is used to determine short and long term maintenance strategies including increased cleaning, root treatment, sewer line repair, or replacement. The condition assessment helps establish the cleaning frequency and populate Old Fort's Capital Improvement Plan. As more condition assessment information becomes available, the priority of capital projects may change. Sewer line repair or replacement projects may also be coordinated with re- paving schedules. Condition assessments document the following details and deficiencies. Characteristics including pipe diameter, and age and type of material 1. Sags in line l( 2. Grease build-up 3. Root intrusion 13 4. Sediment accumulation and encrustation 5. Structural condition, including cracks, corrosion and erosion 6. Joint alignment and movement 7. Reverse slope 8. Obstructions 9. Deformations in line Based on the criteria ratings noted below, the Town of Old Fort assigns an overall rating for each asset. A ranking of each asset, based on its condition assessment rating (see Table 3.1), is then used for prioritizing capital repairs and replacement. Table 3.1 Condition Rating Condition Description Maintenance Required 0 New Normal 1 Excellent Condition Normal 2 Minor Defects Only Minor 3 Backlog Maintenance Significant 4 Requires Major Renewal Renew 5 Almost Unserviceable Replace Assessment Factor Consideration Scale Criticality How critical is the service of this asset? 0 (noncritical) —10 (critical) Performance What level ofperformance is it providing? New to unserviceable (on a scale of 0 to 5) Impact of Failure Is there a process, environmental, or safety issue? 0 (no issue) - 3 (significant) or each im act category Capacity Is it capable of meeting system needs? Undersized — Oversized Remaining Life How much of its design life is used up? Percentage from 0 to 100% Redundancy Does the component have a back up? From 0 (no back up) to 200% d. Staffing and Equipment The Town of Old Fort has staff trained for sewer cleaning, inspection and assessment, and they are deployed in 2 person crews at least once per year for cleaning. Inspection work is coordinated with the Water and Sewer Department staff, with oversight from the Public Works Director. The Water and Sewer Department Director works with the inspection crew on assessing the condition of the collection system, using. Approximately semi-annually, crews are assigned a specific area of the collection system with an associated map and are responsible for cleaning all lines (or, in the case of preliminary evaluation, determining if cleaning is needed) within the assigned area within the specified time frame. Crews receive training on the use of equipment and how to address problems that might be encountered while cleaning the collection system (roots, fats, oils and grease, and manhole condition, including when to call in outside contract services. Crews report back on a semi-annual basis on progress and problems including any C inconsistencies between the map and the actual sewer lines which are noted and submitted with 14 their log to the Public Works Director for entry into the database and correction of mapping or location errors. As the crews perform cleaning and evaluation, the long term cleaning schedule for the entire sub -area is reviewed to determine if any lines designated for long term cleaning need to be cleaned before the crew moves to a new area. Cleaning crews perform manhole inspections during cleaning and approximately 20 manholes are inspected in the average year. The following equipment is available for cleaning: A sewer jetting machine is used to clean most lines. Root saws are attached to the jetting equipment and used as needed. Rodding equipment is used to remove blockages from lines. Brush cutting equipment is used to clean easement lines that are difficult to access with the jet equipment and lines that are difficult to traverse with large jet nozzles. 15 4. GRAVITY LINE PREVENTIVE MAINTENANCE a. Fats, Oils and Grease (FOG) Grease and grease -like products can significantly increase the likelihood of sewer overflows. Grease can also cause blockages or aggravate blockages due to roots or structural deficiencies. Restaurants, cafeterias, and other food service facilities, as well as industrial facilities, can discharge grease as part of their normal sanitary flows that can lead, in time, to blockages, backups and overflows. The discharge of fats, oils and grease (FOG) is regulated through our Sewer Use Ordinance; however, backups can sometimes occur. Areas of the collection system with known grease problems are inspected more often than other areas. The Town of Old Fort routinely assesses the occurrence of greases in the collection Most blockages are found to occur in the commercial district, and where school discharges occur. Although commercial facilities account for a high percentage of the grease blockages, they are not the only contributors of grease to the collection system, as residential areas, in general, also contribute grease to the system. The Town's grease awareness program includes education for commercial/industrial facilities, and for schools and residents. The Town attorney has reviewed the existing sewer use ordinance and found that it grants authority to the Town to regulate discharges to the sewer system, including grease. Old Fort's sewer use ordinance prohibits discharges of grease and other substances to the collection system at levels that interfere with the operation of the system. The ordinance also authorizes inspection of facilities during normal business hours. The Town of Old Fort has enacted a policy and procedures requiring commercial and industrial grease generating facilities to install and maintain a grease interceptor or automatic grease removal devices, and maintain records of maintenance and operation. The policy also includes annual inspections of such devices conducted by the Public Works Staff. If the grease interceptor has not been maintained (with documented removal of accumulated grease and cleaning), has been bypassed, or if significant grease is discovered within the service connection, the Town of Old Fort will issue a letter to the owner giving notice of the ordinance/policy non- compliance and requiring action be taken to prevent further discharge of grease into the system. b. Root Control The Town of Old Fort currently uses mechanical root removal for sewer lines with chronic root problems. Root saw attachments are standard equipment on cleaning trucks. When a crew encounters roots during routine cleaning, a hydraulic saw is attached to the jetter and used to out and remove the roots. The severity of the problem is recorded on the daily log, and if necessary, the pipe section is placed on the list for priority cleaning. Cutting a tree's roots is like pruning the tree, and stimulates root growth into the system. Consequently, mechanical treatment must be repeated every year or two, which is factored into the cleaning schedules. Root control is also a major part of easement maintenance. c. Service Laterals While the Town of Old Fort maintains service laterals from the property line to the sewer main (portions in the public right-of-way), the service lateral from the building to the property line is 16 C the owner's responsibility. The Town of Old Fort will repair laterals that are located in the public right-of-way when responding to service complaints. If a complaint is received and the Water and Sewer Department field crew determines that the problem is limited to the section of the lateral between the property line and the main, the "lower" lateral will be rodded out if needed (at no cost to the customer) if a cleanout is available at the property line If service lateral problems are found to be the result of blockage or a collapse in the portion of the lateral under the property owner's responsibility, the field crew provides the property owner with information of private sewer rodding companies in the immediate area.. 5. EASEMENTS and PAVING: MAINTENANCE AND ACCESS a. Maintenance of Right of Way and Easements Easements give the Town of Old Fort the right to install and maintain sewer and water facilities on property not owned by the the Town. Easements in Old Fort are usually no more than 30 feet wide, but can ran from a lot width feet to several hundred feet in length. Easements are recorded as deed records that are accessed through McDowell County's Registry of Deeds. Easements are important for the Town's ability to operate and maintain the sanitary sewer collection system. Old Fort's goal is that all easements remain clear of any fences, buildings, gardens, trees, shrubs and extensive landscaping, to allow equipment access for maintenance of the collection system. The Town of Old Fort is not liable to repair or replace any such items that are removed in the process of completing repairs or maintenance on the collection system. Crews Care, however, instructed to work with the property owner whenever possible. Maintenance of easements is accomplished in various ways. Easements on privately -owned parcels are often maintained by the owner. The County Building Inspector refers construction questions as they arise, to the Town's Water and Sewer Department. Easements on public land are maintained by the entity responsible for property upkeep. Manholes in easements are inspected as part of the Town's ongoing preventive maintenance program. The Town of Old fort has a program to identify manholes that have been paved over, or are on department maps but not found in the field. b. Street Paving Coordination Old Fort's Water and Sewer Department is responsible for coordinating street resurfacing and ensuring that all utilities are aware of scheduled resurfacing. A prioritized list of streets to be paved in a particular fiscal year schedule is developed as part of the Town's Powell Bill program. This list is distributed to the Water and Sewer Department to facilitate coordination of all underground work. The Water and Sewer Department assesses the condition of its associated infrastructure to determine where repairs may be necessary, and notifies the Town Board as to which streets need underground infrastructure work completed prior to resurfacing. As sewer lines are inspected and assessed under the Cleaning, Inspection and Assessment program, repairs are scheduled in conjunction with the repaving schedule whenever possible. Sometimes work is performed on a priority basis so that repairs are completed on the highest priority street, working in coordination with the Town's paving schedule. In this case, the Cleaning and Inspection schedules are modified to coordinate with the paving schedule. Upon 17 completion of the sewer repairs for an individual street, it is released to the Water and Sewer Department Director for resurfacing. During paving work, the Water and Sewer Department prepares manholes prior to the re -paving of any street with sewer lines. 6. PUMP STATION/FORCE MAIN MAINTENANCE The Town of Old Fort currently does not own or operates any wastewater pump stations. However, this section of this O&M plan is included at this time so that any new pump stations and force mains will be covered. The performance of any pump stations will be monitored through daily inspections. During these inspections, the Water and Sewer Department staff will review pump run hours, totalized flow, wet well levels and alarms. Back-up generators will be exercised monthly. On an annual schedule, the Water and Sewer Department staff will pump the wet wells, remove grease build up, and calibrate the floats. Inspection, maintenance and repairs will be recorded on the Water and Sewer Department tracking system for each station. Logs will be maintained at the Town Hall. If a problem or maintenance issue is encountered, personnel shall report it directly to the Water and Sewer Department Director for resolution. Repairs are a higher priority than routine maintenance. Manufacturer's Operation and Maintenance (O&M) manuals for equipment will be maintained at the Town Hall.. Pump rebuilding, motor rewinds, and other repairs for the pump stations are contracted to a local firm specifically engaged in this type of work. Repairs to motor control centers, flow meters, remote monitoring equipment, valves, and macerators are typically repaired by local electricians In general, any replacement parts that are difficult to acquire will be kept in stock by the Water and Sewer Department; other parts are obtained from local vendors or the manufacturer's service center. As pumps and other parts are replaced, Old Fort will make an effort to standardize pumping station equipment as much as possible. 7. REACTIVE MAINTENANCE This chapter outlines the process used by the Town of Old Fort to respond to non -overflow, unplanned maintenance needs in its collection system. It also provides an overview of responsibilities for emergency events. While Chapter 3 outlines Old Fort's preventive maintenance and emergency response plan details the Town's response procedures for emergency sewer overflows, this chapter is written to address those unscheduled maintenance events that don't result in overflows or backups of sewage into basements. The Sewer Overflow Response Plan is available at the Town Hall. Crews are trained on sewer overflow emergency response as part of that plan. Sewer Overflow Response - is always a priority situation, details are provided in Old Fort's Sewer Overflow Response Plan (SORP). W Responsibilities for reactive maintenance are assigned by the Water and Sewer Department Director based on level of priority for response as follows: a. Corrective Maintenance Most repair needs are identified while conducting routine maintenance, inspections and assessments. Because there is such a wide range of potential unexpected events, it is not possible to prescribe the appropriate repair for every possible scenario, The Town of Old Fort has established a prioritization scheme for determining the timing of repairs. This is based on the types of problems that have occurred in the collection system in the past or could occur in the future. While this contingency analysis focuses on system upsets that would not result in immediate sewer overflow, the response timing is based on the potential for a resulting sanitary sewer overflow. Low -risk items, such as light bulbs and small non -critical appurtenances, are planned for run -to - failure, and as such, are not part of the PM Program. These items are replaced when they fail. When assets critical to the process fail, they are scheduled for corrective maintenance either on an urgent or routine schedule. Some of these repairs are handled under the operations and maintenance account, and some must be put in as capital improvements as part of the Town's asset management activities depending on asset cost and life expectancy. Corrective maintenance repairs include (but are not limited to): • cleaning to eliminate flow problems that are noted during inspections • spot repair or replacement of a pipe that shows signs of deterioration • replacing a rattling or failed manhole cover • responding to, investigating and mitigating customer complaints • repairing system parts subject to vandalism b. Scheduling Scheduling of repairs runs the range from repairing components found to be in substandard condition during inspection, to major, capital -intensive, repair projects, such as a manhole -to - manhole pipe replacement or rehabilitation. An emergency, however, always supersedes scheduled maintenance. Major replacement or rehab may be capitalized outside of the annual operating budget grants and/or loans are available. c. Complaint Response The Water and Sewer Department is responsible for responding to sewer service complaints. Complaints are generally related to sewer stoppages, overflows, or odors. Response is performed by the Water and Sewer Department staff during work hours and by the same staff during off work hours. Complaint response includes both assessing the complaint and resolving the problem. The majority of complaints are related to stoppages in lateral lines. During work hours, a cleaning crew is diverted to remove stoppages if the stoppage is found to be on public property. During non -work hours, a cleaning crew is diverted to remove stoppages if the stoppage is found to be on public property. If stoppages are on private property, the customer is advised to contact a local plumber. 19 8. EQUIPMENT AND TOOL INYENTORY a. Essential Day -to -Day Items The Town of Old Fort provides operations and maintenance crews with the essential work related items they use on a day-to-day routine basis. Should new or replacement equipment or tools be needed, the crew leader notifies the Water and Sewer Department Director. The Director will issue the crew leader stocked items. For non -stocked items, the Director advises the crew leader of a local vendor and requests a purchase order for the needed item(s). The crew leader will then procure the requested items through the local vendor in an "in -stock" format. b. Spare Equipment and Tools The Town of Old Fort keeps a limited supply of spare equipment and tools for personnel. In lieu of maintaining a full supply of spare equipment and tools for personnel, the Town of Old Fort has an annual "supply bid" for essential common equipment and tools. This bid requires the vendor to maintain "in -stock" items listed in the annual bid, and the vendor must have a local storefront for item pick-up. Non -bid equipment and tools can be purchased in amounts up to $500 dollars. The large equipment and tools needed for certain tasks may be obtained through current rental contracts or purchased Town Board approval for permanent acquisition of the item. An inventory of the equipment and tools used by Town of Old Fort to maintain the wastewater collection system is maintained at the Town Hall. 9. CAPACITY MANAGEMENT The Town of Old Fort's collection system has not exceeded design capacity. However, sewer pipes in the Red Town Area are undersized. In light of capacity issues in the Red Town Area, the Town of Old Fort intends to apply for CDBG funding to replace the undersized sewer lines with 8" sewer lines. 10. RESOURCES AND BUDGET a. Budget Process Old Fort's budget process complies with the mandated North Carolina Local Government Commission budget cycle, which requires that the annual budget be completed by June 30`b of each year. For the Collection System operations and maintenance budget, the process begins with last year's numbers and projected needs for one or more years into the future. The Water and Sewer Department works with the Town Board to prepare the new budget. b. Rate Setting, Budgetary Policies and Financial History The Town's rate -setting policies are based on the following principles: 1. Rates and fees will be based on the actual cost to deliver each service. 2. Current rates must be sufficient to cover current costs and to meet all bond covenants. 20 3. Rates will include funding for Capital Improvement Plan projects included in an annually updated ten-year financial plan (both operating and capital). 4. Rate increases will be Implemented in a gradual and predictable manner, avoiding large one- time rate increases. Old Fort's Water and Sewer Department operates as an enterprise Fund. Old Fort's Sewer revenue is generated from user fees, connection fees from new customers, pretreatment permits, fines, interest earnings, and other miscellaneous income. The Old Fort user charge has two components: an administrative service charge and a volume charge based on monthly water usage. Old Fort's sewer system expenses included operation and maintenance, debt service, and capital reserve fund replenishment. c. Historical Rate Review Old Fort's current sewer rate structure is based on metered water usage. Customers are billed monthly for wastewater services based on 100 % of the metered water use. In addition to flow charges, customers are also assessed a base charge to recover fixed costs. See Tables 10.1 and 10.2, for a summary of current user water and sewer rates. Table 10.1. Current Sewer Use Fees Residential/Commercial - In Town $6.00 $4.39 Residential/Commercial — Out of Town $6.00 $8.78 Industries — Up to 100,000 Gal/Month $6.00 $4.39 Industries — Usage above 100,000 Gal/Mo $4.00 Notes: 1. Minimum monthly charge is for all customers regardless of usage. 2. $/1000 gallons up to 100,000 gallons per month. $4.00/1000 gallons for all usage over 100,000 gal/month Table 10.2. Current Water Residential/Commercial - In Town $6.00 $3.47 Residential/Commercial — Out of Town $6.00 $6.93 Industries — Up to 100,000 Gal/Month $6.00 $3.47 Industries — Usage above 100,000 Gal/Mo $3.20 Notes: 1. Minimum monthly charge is for all customers regardless of usage. 2. $/1000 gallons up to 100,000 gallons per month. $3.20/1000 gallons for all usage over 100,000 galhnonth 21 d. Operating and Maintenance Expense Estimated operating expenses for FY 2018-2019 totaled $377,707.. Operating and maintenance expenses include: • Employee salary and compensation • Operating supplies • Utilities • Repair and maintenance • Professional services • Routine capital outlay • Debt service expenses for repair and replacement Current year and projected future expenses are shown in the Town's Sewer Asset Inventory and Assessment Report to which this O&M Plan is attached. Professional Services includes planning and engineering studies for replacement projects. Contractor Services includes contractual work for cleaning sewer lines and manholes, CCTV, and improvements to the collection system map. Routine Capital Outlay includes items that are considered capital assets and are purchased from annual operating revenue rather than through bonds or the capital reserve fund. Items, such as vehicles, specialized maintenance equipment, pumps, motors, office equipment and other smaller items. Debt service is the annual principle and interest payments for bonds, loans and other fiduciary instruments owed by the Town of Old Fort. The debt service supports capital improvement projects. Old Fort's policy is to not accumulate a maximum debt greater than the percent of the operating budget dictated by the NC Local Government Commission. e. Capital Improvement Program Overview The current Capital Improvement Plan (CIP) is part of long-term planning, and has been established in the Town's 2018 Wastewater Asset Inventory and Assessment Report, to which this O&M Plan is attached. The CIP also incorporates the Town's projected needs for maintaining the integrity of the collection system and expanding sewer capacity to accommodate growth when needed. Capital projects have been evaluated in the Town's 2018 Wastewater Asset Inventory and Assessment Report, to which this O&M Plan is attached The Town of Old Fort has determined a number of projects in its Capital hnprovement Plan. The Town of Old Fort has developed a ten-year CIP program that is updated annually. The CIP describes each proposed project, the budgeted cost for the project and the financing source(s). The current CIP will primarily be funded through the capital reserve fund and hopefully with CDBG Grant Funds for the Red Town Area. The capital reserve funds result from the balance of funds remaining after the payment of all 22 operating and maintenance, debt service and other expenses. The reserve funds are primarily used for: • Non -bond funded capital projects • Additional funds for bonded projects • Emergency repair and maintenance f. Capital Improvement Plan The Wastewater Asset Inventory and Assessment Report to which this O&M Plan is attached includes the Town's current 10-Year CIP. The total 10-Year CIP cost exceeds $ 925,000. . 1. Population Growth The Town of Old Fort has been growing slowly for a number of years. In the 1990 census, the population was 732. By 2010, the population had grown to 908, an average growth of 1.2 percent per year. The long range population for Old Fort is expected to reach 944 through the year 2030. 2. Capacity and Fees The Town's wastewater treatment plant has a capacity of 500,000 gallons per day (GPD). This service capacity includes current average sewer demands of 0.1642 MGD. Therefore, the Town has an excellent wastewater treatment reserve capacity. Based on the expected population growth of Old Fort and the use of reserve funds for capital improvements, the sewer fees are expected to remain level for the next 10 years. 3. Capital Facilities Projects and Financing. The total cost of the planned capital projects during the next 10-year period is $925,000. The proposed projects and the annual cost of those projects are noted in the 2018 Wastewater Asset Inventory and Assessment Report to which this O&M Plan is attached, 11. SEWER SYSTEM PREVENTIVE MAINTENANCE PLAN UPDATES a. Plan Update Process The Town of Old Fort completes an annual review of its Preventive Maintenance program during the budget preparation process. This process general begins in January to February each year and is completed by June 30a' each year. The review will consider the progress that has been made in developing and implementing our CIP, the results of our monitoring program described in Section b, below, and will incorporate updates to this Plan including: • Changes to organizational structure, information management, contacts, and system maps, • Changes to information on the collection system, such as the size and age of pipes, to incorporate information on repairs completed during the year, • Incorporation of successful cleaning, inspection and assessment program improvements during the past year, • Changes to our Sewer Use Ordinance, 23 • Updates as the Town evaluates its collection system capacity, • Budget and Capital Planning updates, The sewer inspection history of specific segments of pipe was conducted in 201 S. The data generated from that inspection was used to develop condition ratings. Those condition ratings were used in prioritizing future sewer rehabilitation projects contained in the CIP. b. Monitoring, Measurement, and Program Modifications The Old Fort Water and Sewer Department maintains complaint and blockage records in a log at the Town Hall. The Town also maintains records of cleaning and other preventive maintenance activities, and records problems (e.g., excessive debris, observed manhole defects) identified through regular sewer maintenance activities the same log book. The sewer inventory, mapping and maintenance database, completed in 2018, will be used to track problems to any sewer segment in the sanitary sewer system. Specifically, the Town currently tracks the following parameters with which to measure the effectiveness in reducing SSOs and meeting set goals. • Number of SSOs per year • Volume of SSOs per year • Number of dry weather SSOs per year • Number of SSOs per year by cause (e.g., roots, grease, pipe failure, I/I, pump failure or other deficiency, etc.) • Response time to SSOs and other service calls (time from call received to first responder arriving on site) • Length of gravity sewers cleaned annually • Actual versus scheduled cleaning dates for gravity sewers • Length of gravity sewers CCTV inspected annually • Percent of system rehabilitated (repaired or upgraded) each year • Improvements in capacity due to reductions in 1/I • Safety history/incidents This information will be assessed and reported to the Town Board of Commissioners during the annual budget process. 24 ROY COOPER 60r0rA0r MICHAEL S.

Tony West (ORC) assisted with the records review and facility inspection. The following items are non -compliant with NPDES Permit NC0021229: The splitter box between the aeration basins and secondary clarifiers is non -operable. This is a critical piece of equipment for plant operations and redundancy. Of the 4 clarifiers listed in the permit, 1 is completely decommissioned (likely un-repairable) and 2 are non -operable and require significant maintenance. At least one additional clarifier should be restored to operating condition as soon as is practicable to provide redundancy. While it is recognized that the facility experiences significantly reduced flow due to loss of industry, the permit description of the facility should be revised to include only the number of clarifiers that will be operated. In addition, the following items of significance were noted during the inspection and should be addressed: The EQ basin diffuser piping appears to have reached the end of its design life and should be evaluated for replacement. While Aeration Basin 1 is operating adequately, the floating aerators appear to have reached the end of their design life and should be evaluated for replacement. Aeration Basin 2 is not operated as the ORC states the capacity is not needed. Additionally, the facility should maintain at least one backup aerator.

Page # 1 NPDES yr/mo/day Inspection Type 3I NCO021229 I11 12I 11/11/16 117 18I CI (cant.) Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) I conducted a 'un-announced' Compliance Evaluation Inspection (CEI) of the NPDES system that serves the Town of Old Fort on November 16, 2011. The reason for the CEI was to review the terms, conditions, and modifications of permit NC0021229, upon renewal dated November 1, 2011.The assistance and cooperation of Mr. Tony West, ORC of Old Fort WWTP, in conducting the CEI was greatly appreciated. Based on records reviewed, on -site discussions with Tony, the Old Fort WWTP NPDES system was determined to be in compliance with permit NC0021229. A report is attached for your records and findings are summarized. Site/System Review The current NPDES WWTP System consists of a bar screen, Influent Pump station and flow meter with composite sampler, 'pista' type grit chamber, an equalization basin, 2-0.600 MGD aeration basins ,4 secondary clarifiers , a chlorine contact basin with de -chlorination, and effluent flow meter and composite sampler, as described in the permit. During the Inspection the discharge observed going into the receiving stream designated as `Curtis Creek' in the Catawba River Basin, did not appear to be causing a negative impact, nor were there any indication of foam or visible solids in the discharge. Suggestions/Recommendations The current use of only one aeration basin appears to be functioning well for the Town. The `floating' aerators may be less efficient and cost more to operate than a modified `diffused' aeration system. The WWTP already has `blowers' on -site, used for aeration and mixing of digesters. An evaluation should be conducted to see if aeration modification would benefit the system. On -site observations and discussions with ORC regarding condition of the secondary clarifiers indicate there is deterioration of the `bearings' of the drive systems. This situation can present maintenance issues in addition to cause deterioration of the final effluent. Please review this condition and seek a remedy. The situation can definitely create conditions that support non-compliance with NPDES permit conditions. Composite sampler(s) of Influent and Effluent were operating correctly at the time of the inspection, with the exception of the thermometer(s) located in each refrigeration unit. There was no indication on the thermometers as to each ones `correct/ed' reading. Please review and make note on each of any temperature corrections. The `Flow Meter' used for reporting flow(s) to NCDENR was last calibrated by Tony West, ORC, on July 2011. Tony uses a `ruler' to determine the head over the crest of the V-notch weir, of which the accuracy is not determined. Please modify this method by using a level and square in combination, to more accurately ascertain flow meter calibration. If there are questions or additional information is needed regarding system operation, maintenance, or a NPDES System permit question, please let me know. Thank you for the opportunity to conduct this Compliance Evaluation Inspection.

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) This is the most upstream municipal wastewater system ultimately discharging into the Catawba River; having outstanding operation and maintenance practices are crucial. The facility appears to be well operated. The time and efforts by Tony West are appreciated. At the time of the inspection it did not appear there were pressing maintenance issues with components in operation. However, components not in use, such as clarifier #1 and #2 do have maintenance needs. Old Fort is considering accepting wastewater from Hydrotime. If this venture takes place and flows increase to where clarifier #1 and/or #2 are needed, maintenance (e.g. scum trough, center well etc.) will be needed prior to putting the clarifiers back into operation. Regarding the possible future venture with Hydrotime, it is essential that the Town have in place sufficient pretreatment operations and spill containment. Contact with water quality staff, both Regional and Central, will be pertinent.

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) The time and assistance of Tony West in conducting the Technical Assistance is appreciated. The reason for this Technical Assistance visit was to review past DMR data reported by the facility regarding Total Suspended Solids (TSS) violations that had occurred in February 2007, December 2008, and January 2009. It appears solids violations are occurring at the WWTP during periods of SIU (significant industrial user) shut down. The industry shut down coincides with the same time period of TSS violations. During the Technical Assistance Solids measurements were taken in the EQ basin, the Aeration Basin, and the Return Sludge. Results are as follows: EQ basin = 71 mg/L; Aeration Basin = 4880 mg/L; & Return Sludge = 5170 mg/L. The concentration of solids maintained in the system is a little high for the time of year( most Extended Aeration Activated Sludge) systems maintain 2500 - 3000 mg/L solids in an Aeration Basin during cooler winter months and lower the level down by 500 -750 mg/L during warmer summer months. On site discussions with ORC Tony West indicated system had maintained the high level due to aeration basin foaming problems and loss of pin floc through the secondary clarifiers. At the current time ORC only does weekly Process Control due to lack of needed staff. It is suggested system increase staff level at WWTP and increase Process Control measurements to improve solids wasting, and control solids inventory and maintain compliance. Other parts of the system are not used due to lack of flow to WWTP. These areas are still in need of O & M and require maintenance. The secondary clarifier flow distribution system should be reviewed by a Professional Engineer and determine if "short circuiting" is occurring. By maintaining a high(er) solids inventory in the secondary system, short circuiting can be a contributing factor to TSS violations in the effluent.Review of staffing information from EPA document 430/9-79-013 indicates that a WWTP the size and complexity of Old Fort's should have at least 5 personnel. Sections of the above mentioned document are attached for review. Should additional questions arise or you need more information, please contact me at (828)296-4500.

Comment: Facility currently measures Aeration Basin MLSS and Clar. Eff. TSS 1/week, DO, Sett., and pH as operator time allows. This frequency of measurement is not adequate for effective Process Control. The Town of Old Fort should review staffing needs at the WWTP and Sewer Collection system and increase staff as needed.

I would suggest this basin be utilized for "increased" flow EQ to allow basin and tankage isolation and inspection. Each tank and basin at Old Fort's WWTP should be taken down, inspected, and any needed maintenance performed at least once per year. The current staffing level at the WWTP does not allow for this. EQ basin TSS measured on -site = 1500 mg/L, sample taken for analysis in DWQ lab = 71 mg/L. Aeration Basins Yes No NA NE Page # 3 Permit: NCO021229 Inspection Date: 01/27/2010 Aeration Basins Mode of operation Type of aeration system Is the basin free of dead spots? Are surface aerators and mixers operational? Are the diffusers operational? Is the foam the proper color for the treatment process? Does the foam cover less than 25% of the basin's surface? Is the DO level acceptable? Is the DO level acceptable?(1.0 to 3.0 mg/1) Owner - Facility: Old Fort WWTP Inspection Type: Technical Assistance Comment: Only one of the two existing aeration basins was in service at the time of the Technical Assistance. Aeration currently in place at the Old Fort WWTP consists of "floating" aerators positioned in place with stainless steel "mooring" cables. It is suggested these steel cables be "REPLACED" with polypropolene ski rope with 2 connections per aerator side. This would allow for easier access and maintenance to the aerators, and also allow for improved positioning of the aerators to allow for optimum aeration and mixing hopefully allowing for reduced power consumption. MLSS measurements taken on -site = 5900 mg/L, samples taken and measured in ARO lab = 5170 mg/L. Secondary Clarifier Is the clarifier free of black and odorous wastewater? Is the site free of excessive buildup of solids in center well of circular clarifier? Are weirs level? Is the site free of weir blockage? Is the site free of evidence of short-circuiting? Is scum removal adequate? Is the site free of excessive floating sludge? Is the drive unit operational? Is the return rate acceptable (low turbulence)?

The 4th secondary clarifier is not in service due to degradation of system components. Flow distribution to the secondary clarifiers is controlled by "adjusting" a weir on the effluent leaving the aeration basin. The current method does not allow for "equalized" flow distribution to the clarifiers. It is suggested that Old Fort discuss this deficiency with a Consulting Engineer to determine the most cost and operationally effective manner to address this situation. This may include using a "telescopic and/or modulating valve" to distribute the flow to the secondary clarifiers equally.

(Tracking Number NOV-2019-PC-0504). Permit Number NC0021229. The clarifiers that we have are in very much needed repair, this is just one of our huge issues that we are having difficulty in financing. The Walker Clarifiers are basically need replacing everything inside the weir and everything below the bridges. The contract W62263 with a Mike Fowler. Getting parts and finding someone to do the labor has been very time consuming. We also were hoping to have three bids, but so far at this time we only have one. We would also like for the State to give us some more time to either draw funding from general fund or see another way to finance this project. Applying for grants is not moving fast enough as you can imagine. Please respond back to me, Tony West, or Renee Taylor on suggestions. We will be discussing this in our August town meeting. Thank you for your patience. Sincerely, Rick Hensley Mayor Town of Old Fort "Colonial Ainerica's Western Outpost Until 1756"
