INTRODUCTION The Grassy Branch Sewer Collection System has been a concern for Union County Water for a number of years due to the Grassy Branch Water Reclamation Facility (WRF) frequently exceeding its capacity. Dating back to 2016, the County has conducted several flow monitoring studies to quantify the amount of infiltration and inflow (1-1) entering the system during periods of wet weather. It has also performed several phases of sewer system evaluation activities including smoke testing, manhole inspections and iTracker micro -detection studies to identify the exact sources of 1-1. It has subsequently repaired any of these defects that were identified. At the present time, the County is confident that the problem is simply a lack of capacity since the average dry weather daily flow rate is very close to the treatment capacity of the Grassy Branch WRF. Even minor amounts of 1-1 will cause the WRF to exceed its capacity and potentially result in sanitary sewer overflows (SSOs) in the system. Despite this, the County decided to perform CCTV inspections of all sewer mains and laterals within the Grassy Branch collection system to identify any defects that could potentially allow 1-1 to enter the system. This report presents the findings of these CCTV inspections. The information gathered during the study has been used to identify specific defects within the system and develop repair/rehabilitation recommendations with cost estimates in order to assist the County with reducing 1/1 into the collection system. 11. GRASSY BRANCH COLLECTION SYSTEM INVENTORY The Grassy Branch collection system ends at the WRF just north of Old Fish Road, runs parallel to Grassy Branch, crosses Unionville Road and Sikes Mill Road to Piedmont High School and Middle School. (This system also receives sewer via a force main from Unionville Elementary School) A "Sewer Main Priority Rating Map" is included in Appendix A and shows the full extent of the gravity collection system and study area. This collection system includes approximately 30,868 linear feet of gravity sewer. The mains are a mix of polyvinyl chloride (PVC) and ductile iron pipe (DIP). Table 1, below, lists the footage of each diameter and material of pipe found in the study area.

RESULTS OF FIELD INVESTIGATIONS A. Cleaning and Internal CCTV Inspection All lines were cleaned using a high -velocity jet / vacuum truck in order to remove debris and provide an unobstructed view of the pipe surface. After cleaning, the lines were then visually inspected by means of a closed-circuit television (CCTV) system, which includes a self-propelled tractor and camera unit. The camera is coupled with an inspection system containing both digital video recorders, footage counter and a laptop equipped with IT Pipes video inspection reporting software. Service laterals were inspected using a special system that "launches" a smaller camera up into the lateral from the main. For each mainline section or lateral, an inspection log was prepared showing the location of any structural defects, offset or separated joints, points of infiltration, roots, etc. The log also shows the location of all service connections and upstream and downstream manhole numbers. The complete inspection was also recorded on videotape and captured digitally on MPEG files. A copy of the inspection logs is contained in Appendix B. Digital videos and digital inspection logs for each line segment are included on Appendix D (thumb drive). Once all the lines were cleaned and inspected, the next step was to evaluate each line and prioritize the lines according to condition severity. Based on our evaluations, each defect was assigned a priority rating from 1 to 5. The priority rating system uses the NASSCO Pipeline Assessment and Certification Program (PACP) and Lateral Assessment Certification Program (LACP) methodology described below. • Grade 5 — Defects require immediate attention. Pipe has failed or will likely fail within the next five years • Grade 4 — Severe defects that will become Grade 5 within the foreseeable future. • Grade 3 — Moderate defects that will continue to deteriorate • Grade 2 — Defects that have not begun to deteriorate. • Grade 1 — Minor defects. NASSCO recognizes two families of defects: structural defects and operation and maintenance (O&M) defects. Structural defects are various types of defects within the structure of the pipe including cracks, fractures, broken pipe, collapsed pipe, offset or separated joints, surface damage from expose to hydrogen sulfide gas, etc. Operation and maintenance defects include deposits (grease, sand), roots, infiltration, obstructions, etc. that affect the system's ability to operate properly. NASSCO also assigns each structural and O&M defect with a grade rating corresponding to the severity of the defect (5 the most severe and 1 the least severe). A grade score is Page 2 of 14 Grassy Branch — Condition Assessment Report Union County Water calculated by multiplying the grade rating by the number of occurrences of that grade identified throughout the pipe. The grade scores are summed in their appropriate families (structural and O&M) to calculate the structural defect rating and O&M defect rating. The overall rating is the sum of structural and O&M defect ratings. Each pipe is also assigned a quick rating, which is a four -digit number showing the number of occurrences for the two highest severity grades occurring in that pipe (the number is displayed with the grade rating first followed by the number of occurrences). For example, if the pipe inspected has two grade 5 defects and six grade 4 defects the quick rating would be 5246. Hydrostructures assigns a priority ranking based on the severity of the worst defect contained in the line. Therefore, a line containing a structural collapse (grade 5) would be scored as a priority 5. The results of the priority rating process are provided in the table below. Zero (0) priority 5, one (1) priority 4, thirty-four (34) priority 3, one (1) priority 2, and ninety- one (91) priority 1 mainline pipe sections were identified in the collection system (Table 2 below). A "Sewer Main Priority Rating Map" is provided in Appendix A and shows the location and priority rating for all mainlines inspected as part of this evaluation. CCTV logs for all pipe segments inspected on the system are included in Appendix B.

Two sags were identified that do not require repair. The remaining pipe was found to be in good condition. Operation and Maintenance Defects and Infiltration O&M defects include debris, sand, rocks, grease, infiltration, etc. The sewer cleaning removed most settled / attached debris and deposits. There were very few maintenance defects and only one mainline joint with infiltration that needs a 4' sectional liner. This joint, between DIP and PVC, had a small dripper. See photo below. Cream There was only one service lateral that needs a lateral seal for infiltration that is coming between the service lateral and the mainline section. See photo below. Service at 46' upstream of manhole 2784 has small runner. Page 6 of 14 Grassy Branch — Condition Assessment Report Union County Water B. Service Lateral CCTV Inspection In addition to the PACP inspection of all pipe segments, each service lateral was inspected and prioritized according to the Lateral Assessment Certification Program (LACP). Based on our evaluations, each defect was assigned a priority rating from 1 to 5. The priority rating system uses the NASSCO Pipeline Assessment and Certification Program (PACP) methodology described above. A total of 132 service laterals were located in the collection system at the time of the project and all except 3 were inspected. All were PVC and 4-inches in _diameter. A few had grease, sags, or offset joints, but only one requires repair. Each has been assigned a priority rating and the summary table is provided below. Zero (0) priority 5, one (1) priority 4, one (1) priority 3, eleven (11) priority 2, and one hundred sixteen (116) priority 1 service laterals were identified in the collection system (Table 2 below). A "Sewer Main Priority Rating Map" is provided in Appendix A and shows the location for all service laterals inspected as part of this evaluation. Inspection logs for all the service laterals are included in Appendix C. TABLE 4 — LATERAL PRIORITY RATING SUMMARY Priori 5 0 Priori Priorit 4 3 7 1 1 Priority 2 11 Priority 1 116 Only one service lateral needs to be replaced.

ALTERNATIVES EVALUATION Several methods and technologies are available for the rehabilitation of sewer mains and service laterals. This section discusses the available and most commonly recommended / implemented rehabilitation methods. A. Manhole Rehabilitation and Repairs 1. Pipe Connection Infiltration Pipe connections between the manhole wall and the influent and effluent piping are sometimes found to be sources of infiltration and root intrusion. These connections may lack a boot (typically older brick manholes) and not be adequately grouted or the boot was not properly seated and tightened around the pipe during installation. Infiltration is especially prevalent in deeper manholes, where the hydrostatic pressure from high groundwater levels can cause significant leaks through relatively small cracks and holes. We recommend that leaking pipe connections be sealed by injecting chemical grout pumped through drilled injection ports into the crack or void from the inside of the manhole. The grout will penetrate to the exterior of the manhole, where it will fill any voids and seal the leak from the outside. After the void has been filled with chemical grout, cementitious grout should be used to seal the pipe connection from the inside of the manhole. Estimated Cost: $500.00 per Pipe Connection. B. Sewer Main Rehabilitation and Repairs 1. Open -Cut Point Repairs A point repair consists simply of excavating down to a damaged section of pipe and replacing the damaged section with new pipe. It is used when damage is isolated to one particular area of the pipe, generally less than twenty feet in length. It is also used to repair pipe collapses, sags, and/or offset joints prior to manhole - to -manhole trenchless rehabilitation by CIPP. It can be very disruptive to the surrounding area, especially if the pipe is deep or underneath pavement. It can also be extremely expensive depending upon the location and/or depth of the repair. Estimated Cost: 8" — 12" = $12,500 15" — 18" = $17,500 *Includes bypass pumping, assumes DIP 2. Internal CIPP Sectional Liner (CIPP Spot Repair) Sectional cured -in -place spot repairs are ideal for patching holes and other isolated, non -deformed structural defects. Spot repair patches can be used for infiltration control when hydrophilic 0-rings or caulk is used between the host pipe Page 11 of 14 Grassy Branch — Condition Assessment Report Union County Water and ends of the repair patch. Most manufactures have repair patches available up to 42-inches and lengths of 2, 4, and 8-feet are common. Patches are fiberglass with epoxy resin or typical felt with vinylester resin. Spot repairs are installed with a flow through bladder. The patch is secured to the inflatable bladder, pulled into place, the bladder pressurized to form the patch tightly to the pipe surface and allowed to cure ambiently. Because the bladder is flow through, little or no flow control is required during installation Estimated Cost: 8" —12" _ $5,000 15" —18" _ $9,500 C. Service Lateral Rehabilitation and Repairs The following section discusses service lateral rehabilitation methods including connecting service laterals to the main line. Cost estimates for each method are provided based on similar rehabilitation projects. 1. Open -Cut Replacement This method of repair consists of excavating the defective service lateral and replacing it with a new lateral within the same trench. This method is the most cost effective to rehabilitate shallow service laterals in low traffic areas. Although it obviously requires more excavation, it is the most frequently recommended method for service rehabilitation. Service lateral replacement is only performed from the sewer main to the right-of-way (location of the cleanout). Estimated Cost: $100 per linear foot of service lateral (If the replacement of the lateral includes the replacement or installation of a cleanout and reconnection to the main line, the total cost is usually an additional $2,000 or $3,000.) 2. CIPP Lateral Seal Full Wrap Lateral Seal rehabilitation is a trenchless service connection rehabilitation method used to seal leaking service connections and restore structurally integrity. Full wrap lateral seals are recommended when conflicts or depth increase the difficulty and cost of excavation. A full wrap later seal includes a polyester felt tube with a sewn flange that covers up to 16-inches of the mainline in a full wrap. The use of hydrophilic sealants and silicate resins applied to the backside of the full warp connection enhances the watertight seal. Typically, this wrap includes 2-feet of lateral liner to extend up into the service lateral. Ambient cure polyester or vinylester resins are used. Diameters of 4-inch and 6-inch service lateral rehabilitation are possible with 8-inch to 24-inch mainline wraps. During installation, the mainline must be cleaned and free of all debris. Roots and other debris are removed from the lateral connection. The full wrap lateral seal is loaded on a silicone bladder lateral train and inserted through the downstream rage Iz or l4 Grassy Branch — Condition Assessment Report Union County Water manhole. When the lateral train reaches the connection (as confirmed by standard CCTV equipment), the bladder is inflated and held at the recommended air pressure while the connection seal is allowed to cure. Once cured, the bladder is removed and the service is returned to use. Estimated Cost: $ 10,500.00 per CIPP lateral seal 2. Reconnecting Laterals to Main Line This process consists of reconnecting a lateral to a sewer main by use of a saddle or fitting. It is used to repair break-in taps or other defective connections, which are very common in older collection systems. These connections are very susceptible to ground water infiltration and root intrusion. It is recommended that break-in taps be replaced by a saddle connection. Estimated Cost: $6,000.00 per service lateral 3. Installation of Clean -outs Many older service laterals were installed without clean -outs at the property line (right-of-way). Without them, it can be very difficult to remove blockages that can occur in the laterals. If a clean -out on private property is used, it can be difficult to determine whether the responsibility for removing a blockage lies on the property owner or the municipality. To allow for easier maintenance, we recommend that all service laterals have clean -outs installed at the property line or edge of right-of- way. Estimated Cost: $1000.00 per clean -out Page 13 of 14 Grassy Branch — Condition Assessment Report Union County Water V. REPAIR / REPLACEMENT / REHABILITATION (RRR) RECOMMENDATIONS WITH COST ESTIMATES Overall, the collection system was found to be in very good condition. Only a few active infiltration defects were identified; most were in manholes or at the manhole/pipe connection. Because there are so few repairs, the price of each repair can be expected to be highly inflated if this work is done as a standalone project. We recommend including these few repairs in with another sewer rehabilitation project in order to obtain better overall pricing. TABLE 6: RRR COSTS Estimated Unit Description Quant.

VI. CONCLUSION This report presents the data, results, and recommendations from the evaluation of the Grassy Brach gravity collection system. Based on the CCTV inspection results, there are only a few minor defects in the collection system that need to be addressed. We encourage Union County Water to move forward with the recommendations presented in this study. Following these repair recommendations will reduce 1/1 reaching the WRF. Furthermore, tending to these issues will prevent these defects from getting worse over time. We also recommend that the County include these repairs in with another sewer rehabilitation project for the best possible cost benefit. Hydrostructures, P.A. has extensive experience with trenchless rehabilitation engineering, and we would welcome the opportunity to assist the County with the implementation of RRRs proposed in this report.

Introduction The Grassy Branch Water Reclamation Facility (WRF) Expansion project will expand the treatment capacity of the WRF from 50,000 gallons per day (gpd) to 120,000 gpd. The two alternatives evaluated in this technical memorandum (TM) include summary of unit processes and cost comparison of: (1) installation of a parallel 70,000 gpd package train with flow equalization, sludge storage, aeration tanks, and clarifiers while maintaining the existing 50,000 gpd package train in its current configuration, and (2) installation of packaged 120,000 gpd aeration tanks and clarifiers while reconfiguring the existing aeration tanks to operate as flow equalization volume. Alternative 2 is evaluated with two options: (A) utilizing existing sludge storage and flow equalization tanks for sludge storage; (B) including a new sludge storage tank with the new package plant. Both alternatives will include new influent pumping, chemical storage and feed, blowers, cloth disk filters, UV disinfection, effluent outfall piping, electrical service and switchgear, instrumentation & controls, and general site work.

Effective May 1, 2022, UCW was issued updated effluent limits to the Grassy Branch WRF related to an application for a Special Order by Consent (SOC) to expand the facility from 50,000 gpd to 120,000 gpd. Table 2-1 summarizes the final effluent permit limits for five-day biochemical oxygen demand (BOD5), total suspended solids (TSS), ammonia (NH3-N), and fecal coliform (FC). Table 2-1: Final Effluent Permit Limits Parameter Monthly Average Weekly Average BOD5, mg/L (April 1 through October 31) 5.0 7.5 BOD5, mg/L (November 1 through March 31) 10.0 15.0 TSS, mg/L 30.0 45.0 NH3-N, mg/L (April 1 through October 31) 2.0 6.0 NH3-N, mg/L (November 1 through March 31) 4.0 12.0 Fecal Coliform, geometric mean/100mL 200 400 2.2 Influent Design Flows Influent design flows were developed by Hazen in the Grassy Branch WRF Process Evaluation TM (July 2019). Table 2-2 summarizes the proposed design Annual Average (AA), Maximum Month (MM), Maximum 7-day, and Maximum Day (MD) flows and peaking factors. Table 2-3 summarizes the proposed design annual average and maximum month concentrations and loads. The proposed design influent concentrations were selected based on historical data and typical values for medium strength domestic wastewater. Equipment proposals were requested based upon the design flow parameters listed in the two tables below. Secondary proposals were requested based upon the flow scenario with adequate equalization storage volume to limit peak flow through Grassy Branch WRF to "2Q", or 240,000 gpd.

Alternatives Comparison The following two design scenarios were examined: Alternative 1: Installation of a parallel 70,000 gpd package train with flow equalization, sludge storage, aeration tanks, and clarifiers while maintaining the existing 50,000 gpd package train in its current configuration. Alternative 2: Installation of package 120,000 gpd aeration tanks and clarifiers while reconfiguring the existing aeration tanks to operate as flow equalization volume. Alternative 2 was divided into two subalternates (2A and 2B) that examined two different sludge storage configurations. Both alternatives will incorporate the following new common facilities: • Influent Pumps & Pump Station • Lime Storage & Feed Pumps • Process Blowers • Cloth Disk Filter • UV Disinfection • Effluent Outfall & Piping • Electrical Service & Switchgear • Instrumentation & Controls • General Site Work 3.1 Site Layout Appendix A includes a Parcel Map and the FEMA Floodplain Map associated with the facility. A flow schematic of the existing facilities at Grassy Branch is shown in Figure 3-1. Both alternatives will require extensive site grading to provide a level surface for the proposed facility expansion. The area due south of the existing treatment train where the proposed basins will be located is within the 100-year floodplain. USGS topographic maps denote a secondary stream feeding into Grassy Branch from the pond southwest of the WRF property. All work will likely be within the riparian buffers designated by Union County ordinance 70.030. The existing Union Power Cooperative power distribution utility pole for the site will need to be relocated to accommodate the proposed facility expansion. The existing 150-foot Duke Energy Transmission right-of-way corridor will restrict the available footprint for expansion on the southern portion of the property. The facility's potable water well will need to be decommissioned due to the proposed facility expansion. Union County Water (UCW) Page 4 of 11 Grassy Branch Water Reclamation Facility Expansion Alternatives DRAFT Hazen March 31, 2023 3.2 Common Facilities Influent Pump Station The existing influent pump station will be replaced with a new influent pump station with the same wet well and valve vault configuration. The wet well will have three 5-HP submersible pumps that will operate with two (2) duty pumps and one (1) standby pump. The following design conditions were identified for influent pump selection: • Max Month Flow — 84 gpm at 30-feet TDH • Max Day Flow — 326 gpm at 40-feet TDH Variable frequency drives (VFDs) will be installed to manage variable flows. Submersible pump selections have been requested from Flygt. UCW uses Flygt pumps at their other wastewater treatment facilities and could streamline maintenance by maintaining a single pump manufacturer. Other pump manufacturers can be considered if UCW has additional preferences. Influent Screening The WRF currently relies on a manual bar rack located inside the package plant distribution box. The introduction of a new fine screen sized to meet the increased influent flows listed in Section 2 would increase the plant's screening reliability. A fine screen, such as the Lakeside Raptor Micro Strainer, could serve as a centralized screening facility for the WRF for Alternative 2. An initial selection would consist of the following features: • 326 gpm capacity • 17-feet x 3-feet footprint • 2-hp Drive • 15 gpm at 60 psi water requirement Alternative 1 is scoped herein with a screen for each package train due to the complexity of piping from a single screen to both sets of aeration tanks. Cloth Disk Filter A single cloth disk filter system would replace the existing mixed media filter system at the WRF. Initial pricing and selection of cloth disk filter was based on the Kruger system, which is used at other UCW wastewater treatment facilities. The initial selection from Kruger consists of the following features: • 326 gpm capacity • Footprint: 100-square feet Union County Water (UCW) Page 5 of 11 Grassy Branch Water Reclamation Facility Expansion Alternatives DRAFT Hazen March 31, 2023 • Number of Discs: 2 • Backwash Requirement: 14 gpm Under Alternative 2, greater equalization storage volume may result in adequate volume to limit peak flow through the plant to "2Q", or 240,000 gpd. Per conversations with Kruger, this could allow the system selection to remove one of the two required disk filters (approximately $10,000 per disk filter). Given the minimal cost savings and the built-in system redundancy of having multiple disk filters, it is recommended to install the higher capacity unit. Ultraviolet (UV) Disinfection A new UV Disinfection system will be required to meet the updated capacity requirements. The new system would allow for one duty and one standby unit (i.e. banks) to meet the peak day flow. The selection consists of the following features: • 326 gpm capacity • Footprint: 24-feet x 3-feet • Number of Banks: 2 • Number of Lamps per Bank: 16 • UV Transmittance @ 253.7 nm: 65% (to be validated during design) • Can be installed in Series or Parallel The initial pricing and selection of a UV disinfection system was based on a TrojanUV system, which is used at other UCW wastewater facilities. Under Alternative 2, greater equalization storage volume may result in adequate volume to limit peak flow through the plant to "2Q", or 240,000 gpd. Per conversations with TrojanUV, this could adjust the system selection to eight (8) lamps per bank. The smaller flow compatible unit would result in a $20,000 reduction in capital costs. Given the minimal cost savings and reliability at higher flows, it is recommended to install the higher capacity unit. Miscellaneous Work The following describes miscellaneous work that will be required for both design alternatives: New process piping will be installed to accommodate all related facility expansion work. For both alternatives, flow will be split between the existing treatment train and the proposed treatment train using valves and magnetic flow meters. • A new effluent outfall will be constructed adjacent to the existing outfalI on Crooked Creek. • Lime, for supplementary alkalinity addition, will be pumped to the influent splitter box for each alternative. Currently lime is fed into the equalization portion of the package treatment plant. Operators have reported lime buildup at the feed point within the equalization tank. Union County Water (UCW) Page 6 of 11 Grassy Branch Water Reclamation Facility Expansion Alternatives DRAFT Hazen March 31, 2023 Only the existing equalization and sludge holding tanks were repaired and recoated in the most recent upgrade project. The remaining interior tank coatings have reached the end of their useful service life and these tanks will need to be recoated. The existing interior aeration basin coatings (both alternatives) and clarifier coatings (Alternative 1 only) should be completely removed by sandblasting and the interior surfaces recoated with a high solids epoxy system specifically designated for wastewater immersion. After sandblasting, the cleaned steel surfaces should be inspected for damage and surface loss. Any damaged areas of steel walls, floors, welds or stiffeners should be repaired or replaced prior to recoating. • The existing mixed media filters and UV disinfection facilities will be demolished. A new potable water line that will serve the facility to be installed and fed from the water main on Old Fish Road. Electrical system including utility service, generator, automatic transfer switch, switchgear, and VFDs. Systems integration of all new facility improvements. 3.3 Alternative 1 Along with the proposed improvements described in Section 3.2, Alternative 1 will incorporate a new 70,000 gpd package treatment plant to operate in parallel to the existing 50,000 gpd package treatment train. A flow schematic for Alternative 1 is shown in Figure 3-2. Flow Equalization The existing package treatment plant has a flow equalization volume of 15,400 gallons. The flow equalization tank has two dedicated 2-horsepower (HP) rotary lobe positive displacement (PD) blowers to supply process air to the system via coarse bubble diffusers. The proposed new package treatment plant would include a flow equalization chamber of approximately 23,100 gallons to provide a total equalization volume of 38,500 gallons. The proposed flow equalization tank would include a coarse bubble aeration system and three 5-HP rotary lobe PD blowers that would operate in two duty, one standby configuration. Equalized flow will be repumped to the influent distribution box of the package plant. Secondary Treatment The existing package treatment plant consists of two 25,000 gallon aeration basins and two 10-foot diameter secondary clarifiers. WAS from the secondary clarifiers is routed to a 9,000 gallon sludge holding tank. Aeration basins and sludge holding tanks utilize two 7.5-HP rotary lobe PD blowers to supply process air via coarse bubble diffusers. Currently plant staff must operate both blowers as duty blowers to meet the aeration demand. Union County Water (UCW) Page 7 of 11 Grassy Branch Water Reclamation Facility Expansion Alternatives DRAFT Hazen March 31, 2023 The proposed new package treatment plant would include two 35,000 gallon aeration basins and two 14- foot diameter secondary clarifiers. WAS from the proposed secondary clarifiers will be routed to a new 11,000 gallon sludge holding tank. The proposed aeration basins and sludge holding tanks would include a coarse bubble aeration system and three 10-HP rotary lobe PD blowers that would operate in a two duty, one standby configuration. The blowers would be configured to operate on VFDs to provide operation flexibility. The initial pricing and selection of a secondary treatment system was based on a Pro -Water Systems package treatment plant. The initial pricing and selection of aeration blowers was based on Aerzen rotary lobe PD blowers, which are used at other UCW wastewater facilities. 3.4 Alternative 2 Along with the proposed improvements described in Section 3.2, Alternative 2 will incorporate a new 120,000 gpd package treatment plant. Flow Equalization Under this alternative the two 25,000 gallon aeration tanks in the existing package treatment plant would be converted to flow equalization thus creating a total flow equalization volume of 50,000 gallons. The proposed flow equalization system is intended to leverage the existing aeration blowers and diffusers. Equalized flow will be drained to the influent pump station manhole. Secondary Treatment The proposed new package treatment plant would include two 60,000 gallon aeration basins and two 16- feet diameter secondary clarifiers. WAS could be stored in two possible ways in this alternative, thereby differentiating Alternatives 2A and 213: Alternative 2A: The flow equalization and sludge holding tanks within the existing package treatment plant would be refurbished to act as a single sludge holding tank with a proposed volume of 24,500 gallons. New piping and a WAS pump would be required in this scenario to direct flow from the new basins to the sludge holding tank. A flow schematic for Alternative 2A is shown in Figure 3-3. • Alternative 213: A new sludge holding tank at the head of the proposed package treatment plant with a proposed volume of 19,000 gallons. This system would utilize the pressure from the RAS airlift system, like the currently installed package treatment plant, to transfer WAS from the secondary clarifiers to the sludge holding tank. A flow schematic for Alternative 213 is shown in Figure 3-4. Union County Water (UCW) Page 8 of 11 Grassy Branch Water Reclamation Facility Expansion Alternatives DRAFT Hazen March 31, 2023 The proposed aeration basins would include a coarse bubble aeration system and three 15-HP rotary lobe PD blowers that would operate in a two duty, one standby configuration. The blowers would be configured to operate on VFDs to provide operation flexibility. A site layout of Alternative 213 is shown in Figure 3-5. The initial pricing and selections are based on Pro -Water Systems and Aerzen, similar to Alternative 1. The following work in the existing package treatment plant is recommended under Alternative 2B: Interior walls of the existing package treatment plant will be partially removed to consolidate equalization volume. Holes will be cored into the dividing wall between the two proposed equalization cells to create a single equalization system. The existing secondary clarifiers will be demolished. The existing flow equalization and sludge holding volume will be abandoned in -place.

Operational Considerations UCW may consider alternative configurations depending on how they choose to operate the selected alternatives, including the following: • Sole sourcing of certain equipment and systems could streamline operation and maintenance of UCW's wastewater treatment facilities. Package plants are available in two different options: (1) field assembled plants and (2) pre - manufactured plants. The existing package plant at Grassy Branch WRF is a field assembled plant. The existing package plant at Olde Sycamore WRF is a pre -manufactured plant. Pre - manufactured plants are limited to dimensions that allow for ground transport, whereas field assembled plants allow for basin dimensions to be optimized. Field assembled plants were considered in the development of the Section 4 Cost Summary. • Under Alternative 1, flow into each package treatment plant would be controlled by modulating valves and flowmeters. The modulating valves may create a restriction that could lead to nuisance valve clogging. A single screen channel upstream of the influent pump station may be considered as an alternate. • Under Alternative 2A, WAS transfer to the sludge holding tanks from the proposed treatment train requires a transfer pump. Package plants, like the existing treatment train, typically have the sludge holding tank at the head of the package treatment train and WAS is transferred using airlift piping. • The proposed site plan should provide adequate access for sludge hauling and chemical delivery vehicles. Currently large transportation vehicles must back into the plant property. • Addition of a potable water service connection from Old Fish Road. • Addition of a bathroom and/or eyewash station (not included in this TM).

Ideal for small treatment facilities, the Raptor® Micro Strainer utilizes a semicircular screenings basket to capture debris, such as plastics, hygienic articles and fibers. The Raptor® Micro Strainer features, including the screw conveyor, are all stainless steel construction (304 or 316) to handle the most severe conditions. At 35'to 45' angle of inclination, the Raptor® Micro Strainer provides high removal efficiency using a perforated plate or wedge wire basket with small openings ranging from 0.04 to 0.25 inches (1 to 6 mm). A central screw conveyor with a cleaning brush removes the captured solids from the screenings basket and transports the debris for disposal. As the solids are being conveyed, they are macerated to break down large fecal matter, and then washed using a two -stage screenings wash system to return organic material back to the wastewater stream. The washed screenings are compacted and dewatered prior to being discharged, thereby reducing the volume and weight to a dry solids content of 40 percent, ultimately reducing disposal cost. Raptor® Micro Strainer Raptor® Micro Strainer with Bagger with Weather Protection Superior design and construction • All stainless steel construction resists corrosion • Combines 4 processes in one unit (screens, washes, compacts and dewaters) • Dual spray wash system provides cleaner discharge screenings • Integrated compaction zone reduces volume and weight for reduced disposal cost • Enclosed transport tube and optional bagger attachment reduce odors • Hinged support to pivot screen out of channel for maintenance • Removable bearing bars promote longer brush life without disassembling the screen • Tank -mounted screens and explosion -proof designs are available • Optional weather protection system protects to 13' F below zero (minus 25' C) Round openings are available in sizes of 0.12 inch and larger Wedge wire screens are available in bar spacing of 0.12 inch and smaller Raptor® Vertical Micro Strainer for Applications with Limited Space The Lakeside Raptor® Vertical Micro Strainer is designed specifically to fit into limited access areas such as wet wells, submersible pump stations, and underground vaults. Similar to the inclined Raptor® Micro Strainer, it combines the functions of screening, compacting and conveying into a single unit. The Raptor® Vertical Micro Strainer incorporates a shafted screw with cleaning brush attached to the flights in the basket area to convey captured material for disposal. The split basket design provides easy access to the brush assembly. The screen basket is either View of Slide Rail and Head Box Durability and performance perforated plate for wastewater applications or wedge wire for special/industrial applications. An optional slide rail system is available to allow easy removal of the screen from the wet well or vault. A quick connect flange is used to make sure the screen's head box lines up with the influent pipe connection. Raptot4 Vertical Micro Strainer with Bagger • Shafted screw for most effective conveying Raptor® Vertical Dewatering/ Micro Strainer Compaction Zone • Accessible composite bearing bars • Split screenings basket for easy service • Optional slide rail system for screen removal • Discharge chute and optional bagger • Automated controls _ Screw Conveyor Vertical applications you can rely on • Submersible pump stations and manholes • Tank -mounted packaged headworks • Package treatment systems • Industrial systems Influent Se WE Connection Slide Rail Head Box Treatment equipment and process solutions from Lakeside Equipment Corporation Lakeside offers a wide range of equipment and systems for virtually all stages of wastewater treatment from influent through final discharge.

Statement Regarding Competitive Transparency Veolia takes all issues surrounding probity and confidentiality very seriously in all of its dealings with competitors and stakeholders. In this spirit and for the sake of transparency, we inform you that the publicly traded parent company Veolia Environnement S.A., recently acquired a 29.9% interest in Suez S.A ("Suez') and launched a public bid for the remainder of Suez' share capital. Consistent with our commitment to competition law compliance, Veolia will continue to act entirely independent of Suez until all relevant antitrust approvals of Veolia's acquisition of Suez have been obtained and we will of course let you know if this would change before the end of the tender proceedings. Specifically, none of Veolia's representatives sit on the board of Suez, Veolia has no influence over the strategy or operations of Suez, and Veolia has no access to competitively sensitive information about Suez's operations. Accordingly, Veolia's ongoing project to acquire Suez will have no effect on our participation in, or response to, this tender.

The facility serves three schools, two subdivisions, and several additional private parcels. The facility has been issued Notice of Violations (NOVs) for flow, biochemical oxygen demand (BOD), ammonia, total suspended solids, fecal coliform, and pH over the last several years dating back to 2018. It has been determined that the majority of the NOVs have been a result of record rainfall events; however, over -allocation of sewer capacity has also contributed to discharge permit compliance issues. The County has actively been addressing inflow and infiltration (I & I), but the over -allocation of sewer capacity must be addressed through a plant expansion. The County has entered into a Special Order of Consent (SOC) to address the capacity issues through expansion of the facility, and a schedule of compliance is included in Appendix E. The facility's NPDES discharge permit includes provisions for expansion to 0.120 MGD upon issuance of an Authorization to Construct from NCDEQ. The effluent discharge limits for the facility at 0.120 MGD are summarized in Table 1 below, and the complete NPDES discharge permit is included in the Appendix D.

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) internet 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. The eDMR system may be accessed at: https://deq.nc.gov/about/divisions/water-resources/edmr. 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 following address: NC DEQ / Division of Water Resources / Water Quality Permitting Section ATTENTION: Central Files 1617 Mail Service Center Raleigh, North Carolina 27699-1617 See "How to Request a Waiver from Electronic Reporting" section below. Monitoring results obtained during the previous month(s) shall be summarized for each month and reported via the eDMR system no later than the last calendar day of the month following the completed reporting period. 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, 2025, the permittee must electronically report the following compliance monitoring data and reports, when applicable: Page 7 of 9 DocuSign Envelope ID: 08D06D03-27E2-4B5F-83BC-46360B2F33B4 NPDES Permit NCO085812 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). 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: https://www.federalre_ig ster.gov/documents/2015/10/22/2015- 24954/national-pollutant-discharge-elimination-system-npdes-electronic-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 permittee must first submit an electronic reporting waiver request to the Division.

Definitions 2/Month Samples are collected twice per month with at least ten calendar days between sampling events. These samples shall be representative of the wastewater discharged during the sample period. 3/Week Samples are collected three times per week on three separate calendar days. These samples shall be representative of the wastewater discharged during the sample period. Act or "the Act" The Federal Water Pollution Control Act, also known as the Clean Water Act (CWA), as amended, 33 USC 1251, et. seq. Annual Average The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal coliform, the geometric mean of such discharges. Arithmetic Mean The summation of the individual values divided by the number of individual values. Bypass The known diversion of waste streams from any portion of a treatment facility including the collection system, which is not a designed or established or operating mode for the facility. Calendar Day The period from midnight of one day until midnight of the next day. However, for purposes of this permit, any consecutive 24-hour period that reasonably represents the calendar day may be used for sampling. Calendar Week The period from Sunday through the following Saturday. Calendar Quarter One of the following distinct periods: January through March, April through June, July through September, and October through December. Composite Sample A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 mL in such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The Director may designate the most appropriate method (specific number and size of aliquots necessary, the time interval between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically. Composite samples may be obtained by the following methods: (1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow. (2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour period of discharge and combined proportional to the rate of flow measured at the time of individual sample collection, or (3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period with the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow measurement between sample intervals shall be determined by use of a flow recorder and totalizer, and the preset gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at the treatment system, or Version 1110912011.2 DocuSign Envelope ID: 08D06D03-27E2-4B5F-83BC-46360B2F33B4 NPDES Permit Standard Conditions Page 2 of 18 (4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at a constant time interval. Use of this method requires prior approval by the Director. This method may only be used in situations where effluent flow rates vary less than 15 percent. The following restrictions also apply: ➢ Influent and effluent grab samples shall be of equal size and of no less than 100 milliliters ➢ Influent samples shall not be collected more than once per hour. ➢ Permittees with wastewater treatment systems whose detention time < 24 hours shall collect effluent grab samples at intervals of no greater than 20 minutes apart during any 24-hour period. ➢ Permittees with wastewater treatment systems whose detention time exceeds 24 hours shall collect effluent grab samples at least every six hours; there must be a minimum of four samples during a 24-hour sampling period. Continuous flow measurement Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance activities on the flow device. Daily Discharge The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as the total mass of the pollutant discharged over the day. For pollutants expressed in other units of measurement, the "daily discharge" is calculated as the average measurement of the pollutant over the day. (40 CFR 122.2; see also "Composite Sample," above.) Daily Maximum The highest "daily discharge" during the calendar month. Daily Sampling Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the permit. Sampling shall be conducted on weekdays except where holidays or other disruptions of normal operations prevent weekday sampling. If sampling is required for all seven days of the week for any permit parameter(s), that requirement will be so noted on the Effluent Limitations and Monitoring Page(s). DWR or "the Division" The Division of Water Resources, Department of Environmental Quality. Effluent Wastewater discharged following all treatment processes from a water pollution control facility or other point source whether treated or untreated. EMC The North Carolina Environmental Management Commission EPA The United States Environmental Protection Agency Facility Closure Cessation of all activities that require coverage under this NPDES permit. Completion of facility closure will allow this permit to be rescinded. Geometric Mean The Nth root of the product of the individual values where N = the number of individual values. For purposes of calculating the geometric mean, values of "0" (or "< [detection level]") shall be considered = 1. Grab Sample Individual samples of at least 100 mL collected over a period of time not exceeding 15 minutes. Grab samples can be collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream samples).

Instantaneous flow measurement The flow measured during the minimum time required for the flow measuring device or method to produce a result in that instance. To the extent practical, instantaneous flow measurements coincide with the collection of any grab samples required for the same sampling period so that together the samples and flow are representative of the discharge during that sampling period. Monthly Average (concentration limit) The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar month. In the case of fecal coliform or other bacterial parameters or indicators, the geometric mean of such discharges. Permit Issuing Authority The Director of the Division of Water Resources. Quarterly Average (concentration limit) The arithmetic mean of all samples taken over a calendar quarter. Severe property damage Substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage excludes economic loss caused by delays in production. Toxic Pollutant: Any pollutant listed as toxic under Section 307(a)(1) of the CWA. Upset An incident beyond the reasonable control of the Permittee causing unintentional and temporary noncompliance with permit effluent limitations and/or monitoring requirements. An upset does not include noncompliance caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation. Weekly Average (concentration limit) The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar week. In the case of fecal coliform or other bacterial parameters or indicators, the geometric mean of such discharges. Section B. General Conditions 1.

Proper Operation and Maintenance The Permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the Permittee to achieve compliance with the conditions of this permit. Proper operation and maintenance also includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires the Permittee to install and operate backup or auxiliary facilities only when necessary to achieve compliance with the conditions of the permit [40 CFR 122.41(e)]. NOTE: Properly and officially designated operators are fully responsible for all proper operation and maintenance of the facility, and all documentation required thereof, whether acting as a contract operator [subcontractor] or a member of the Permittee's staff. 3. Need to Halt or Reduce not a Defense It shall not be a defense for a Permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the condition of this permit [40 CFR 122.41(c)]. 4. Bypassing of Treatment Facilities a. Bypass not exceeding limitations [40 CFR 122.41(m)(2)] The Permittee may allow any bypass to occur which does not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the provisions of Paragraphs b. and c. of this section. b. Notice [40 CFR 122.41(m)(3)] (1) Anticipated bypass. If the Permittee knows in advance of the need for a bypass, it shall submit prior notice, if possible at least ten days before the date of the bypass; including an evaluation of the anticipated quality and effect of the bypass. (2) Unanticipated bypass. The Permittee shall submit notice of an unanticipated bypass as required in Part II.E.6. (24-hour notice). c. Prohibition of Bypass (1) Bypass from the treatment facility is prohibited and the Permit Issuing Authority may take enforcement action against a Permittee for bypass, unless: (A) Bypass was unavoidable to prevent loss of life, personal injury or severe property damage; (B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate backup equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and (C) The Permittee submitted notices as required under Paragraph b. of this section. (2) Bypass from the collection system is prohibited and the Permit Issuing Authority may take enforcement action against a Permittee for a bypass as provided in any current or future system -wide collection system permit associated with the treatment facility.

Definitions In addition to the definitions in Part II of this permit, the following definitions apply to municipal facilities: Indirect Discharge or Industrial User Any non -domestic source that discharges wastewater containing pollutants into a POTW regulated under section 307(b), (c) or (d) of the CWA. [40 CFR 403.3 (i) and 0) and 15A NCAC 02H .0903(b)(11)] Interference Inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which causes or contributes to a violation of any requirement of the Permittee's (or any satellite POTW's if different from the Permittee) NPDES, collection system, or non -discharge permit or prevents sewage sludge use or disposal in compliance with specified applicable State and Federal statutes, regulations, or permits. [I 5A NCAC 02H .0903(b)(14)] Pass Through A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with discharges from other sources, causes a violation, including an increase in the magnitude or duration of a violation, of the Permittee's (or any satellite POTW's, if different from the Permittee) NPDES, collection system, or non -discharge permit. [15A NCAC 02H .0903(b)(23)] Publicly Owned Treatment Works (POTW) A treatment works as defined by Section 212 of the CWA, which is owned by a State or local government organization. This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T .0402, only if it conveys wastewater to a POTW treatment plant. The term also means the local government organization, or municipality, as defined in section 502(4) of the CWA, which has jurisdiction over indirect discharges to and the discharges from such a treatment works. In this context, the organization may be the owner of the POTW treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of POTW may be referred to as a "satellite POTW organization." [15A NCAC 02H .0903(b)(26)] "Significant Industrial User" or "SIU" An Industrial User that discharges wastewater into a publicly owned treatment works and that [15A NCAC 02H .0903(b)(33)]: 1. Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW (excluding sanitary, noncontact cooling and boiler blowdown wastewaters); or 2. Contributes process wastewater which makes up five percent or more of the NPDES or non -discharge permitted flow limit or organic capacity of the POTW treatment plant. In this context, organic capacity refers to BOD, TSS and ammonia; or 3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or 4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement, or the POTW's effluent limitations and conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options; 5. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting the criteria in paragraphs 1 or 2 of this definition above has no reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement, the POTW's effluent limitations and conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options, and thus is not a Significant Industrial User (SIU); or 6. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a non -significant categorical Industrial User. Section B. Publicly Owned Treatment Works (POTWs) Version 1110912011.2 DocuSign Envelope ID: 08D06D03-27E2-4B5F-83BC-46360B2F33B4 NPDES Permit Standard Conditions Page 15 of 18 All POTWs must provide adequate notice to the Director of the following [40 CFR 122.42(b)]: 1. Any new introduction of pollutants into the POTW from an indirect discharger, regardless of the means of transport, which would be subject to section 301 or 306 of CWA if it were directly discharging those pollutants; and 2. Any substantial change in the volume or character of pollutants being introduced by an indirect discharger as influent to that POTW at the time of issuance of the permit. 3. For purposes of this paragraph, adequate notice shall include information on (1) the quality and quantity of effluent introduced into the POTW, and (2) any anticipated impact that may result from the change of the quantity or quality of effluent to be discharged from the POTW. Section C. Municipal Control of Pollutants from Industrial Users. 1. Effluent limitations are listed in Part I of this permit. Other pollutants attributable to inputs from Industrial Users discharging to the POTW may be present in the Permittee's discharge. At such time as sufficient information becomes available to establish limitations for such pollutants, this permit may be revised to specify effluent limitations for any or all of such other pollutants in accordance with best practicable technology or water quality standards. 2. Prohibited Discharges a. The Permittee shall develop and enforce their Pretreatment Program to implement the prohibition against the introduction of pollutants or discharges into the waste treatment system or waste collection system which cause or contribute to Pass Through or Interference as defined in 15A NCAC 02H .0900 and 40 CFR 403.

(DRAFT) North Carolina License C-0381 June 28, 2019 To: Union County Department of Public Works From: Jim Struve, PE, Hazen and Sawyer (Hazen) Mary Sadler, PE, Hazen Joe Rohrbacher, PE, Hazen Michael Parker, PE, Hazen Amanda Ford, Hazen Engineer Certification for Grassy Branch Water Reclamation Facility Special Order by Consent Introduction This process certification is in support of the Union County Public Works (UCPW) application for a Special Order by Consent (SOC) for the Grassy Branch Water Reclamation Facility (WRF). This correspondence is an independent professional report on the status of the Grassy Branch WRF to meet the existing National Pollutant Discharge Elimination System (NPDES) permit limits during the period the WRF will be operating under the SOC. The following narratives specifically address the SOC application requirements. It should be noted that all engineering determinations are supported by a detailed process evaluation published separately from this signed and sealed certification. 2. Summary of Existing WRF Infrastructure The Grassy Branch WRF is an extended aeration package treatment plant (PTP) constructed by Hydro - Aerobics Package Wastewater Treatment Systems in 1997. The WRF is permitted for a maximum month design flow of 50,000 gallons per day (gpd), or 0.05 million gallons per day (mgd). Union County operates the facility NPDES permit NC0085812. Table 2-1 summarizes the final effluent permit limits for five-day biochemical oxygen demand (BOD5), total suspended solids (TSS), ammonia (NH3-N), and fecal colifonn. The Grassy Branch WRF consists of coarse screening, flow equalization, two conventional aeration basins with coarse bubble diffusers, two secondary clarifiers, a sand filter, and ultraviolet (UV) disinfection. Waste activated sludge (WAS) is processed in an aerobic digester for volatile solids reduction. The digested solids are then pumped to a tanker truck and transported to the Crooked Creek WRF for further stabilization. Table 2-2 summarizes the design criteria of the existing Grassy Branch WRF infrastructure.

Flow Evaluation The historical data indicate that influent flows in excess of the permitted design capacity of the WRF have resulted in final effluent pennit violations for flow, conventional pollutants, and bacterial pollutants. The County has attributed the majority of the Notice of Violations (NOVs) to record rainfall events in the region. The County also acknowledges that more sewer connections have been allocated to the Grassy Branch WRF than available capacity. Hazen recommends a permanent increase in the design maximum month flow from 0.05 mgd to 0.120 mgd. Engineer Certification for Grassy Branch Wafer Reclamation Facility Page 3 of Two parallel analysis were ran to verify the proposed 120,000 gpd maximum month design capacity. The first analysis used the average day wastewater flow rates published in 15A NCAC 02T .0114 (Wastewater Design Flow Rates). The wastewater unit flow rates for schools and dwelling units were applied to the number of students and homes served by the Grassy Branch WRF. Due to the proximity to schools, an assumption of three bedrooms per dwelling unit was used in the analysis. The second flow analysis used a Hazen and Sawyer statistical approach for evaluating flow metrics and peaking factors. Table 3-4 summarizes the proposed design annual average for both analyses. Both calculation methods result in an annual average flow within 20%. The statistically -derived maximum month, maximum week, and maximum day peaking factors are also summarized in Table 3-4. The more conservative annual average flow of 67,000 gpd was used to fully account for the impact of the seasonal flow variation attributed to the three schools.

The calculations assume three bedrooms per dwelling unit due to the proximity to schools. 4. Evaluation and Optimization of Existing Treatment Units 4.1 Historical Influent Characterization Data Tables 4-1 and 4-2 summarize the maximum month, maximum week (e.g., 7-day), and maximum day peaking factors (PF) and influent concentrations and loads, respectively. Data was evaluated from 2015 through 2018. Data from the year 2019 does not account for the impact of the seasonal flow variation and Engineer Certif-mation for Grassy Branch Water Reclamation Facility Page 4 of 9 am was therefore not included in the analysis. A statistical approach was used for evaluating influent characterization metrics and peaking factors. The original design influent loads and concentrations for the WRF are not known, as the criteria were not provided in the manufacturer's Wastewater Treatment Systems Operations and Maintenance (O&M) manual. The proposed design concentrations and loads for the Grassy Branch WRF improvements project are summarized in Table 4-3. Table 4-1: Influent Flow and Peaking Factors Parameter 2015 2016 2017 2018 Maximum month peaking factor 1.94 1.65 1.74 1.91 Maximum week (7-day) peaking factor 2.98 3.44 2.70 2.72 Maximum day peaking factor 7.76 7.00 6.74 6.72 Table 4-2: Annual Average Influent Concentrations and Loads Parameter 2015 2016 2017 2018 BOD5, mg/L 135 185 217 203 BOD5, Ib/d 46 59 69 87 TSS, mg/L 184 325 462 458 TSS, Ib/d 63 98 137 170 NH3-N, mg/L 33 33 27 29 NH3-N, Ib/d 10 11 9 11 Table 4-3: Proposed Influent Design Concentrations and Loads TSS 250 140 1.2 1.5 2.0 BOD5 250 140 1.2 1.5 2.0 TKN 40 22 1.2 1.5 2.0 NH3-N 26 15 1.2 1.5 2.0 TP 5.0 2.8 1.2 1.5 2.0 Engineer Certification fca Grasgy Branch Water Reclamation Facility Page 5 of 9 4.2 Influent Pumps The existing influent pumps are rated at 130,000 gpd each at 15 feet of total dynamic head (TDH), which allows for 260,000 gpd with both units in service. The existing pumps cannot be further optimized and do not have sufficient capacity for the proposed maximum month design flow. Additional pumps will be needed to provide adequate capacity with redundancy for the proposed improvements. 4.3 Influent Screening lnfluent screening is comprised of a manual coarse bar screen designed for a peak hour flow of 150,000 gpd (e.g., 2.5 times the maximum month design flow of 50,000 gpd). The existing bar screen cannot be further optimized. Additional screening unit(s) are required as the existing screen does not have adequate capacity to meet the proposed maximum month design flow. 4.4 Plow Equalization Existing flow equalization consists of two 7,700-gallon basins, or 15,400 gallons total volume. The existing flow equalization basins cannot be further optimized, as the basins do not provide adequate hydraulic retention time to attenuate the proposed maximum month design flow. Additional equalization volume is required as part of the facility improvements. 4.5 Secondary Treatment Train The secondary treatment process consists of a 50,000 gpd (e.g., two trains in service) conventional aeration activated sludge process. The PTP is equipped with coarse bubble diffusers and two rotary lobe positive displacement blowers. The aeration basins were designed to provide a 24-hour hydraulic retention time at the current maximum month design flow of 0.05 mgd. However, only 15 hours of hydraulic retention time is provided at current flows. The WAS flow is not measured nor were solids hauling records available for the determination of the solids retention time (SRT). The positive displacement blowers and coarse bubble aeration system does not have adequate capacity to treat the existing annual average, maximum month, maximum week, and maximum day loads with one blower out of service. Based on the available hydraulic, process, and equipment capacity, the secondary process cannot be further optimized to treat additional flow. New process volume and aeration equipment is required as part of the facility improvements for the proposed maximum month design flow. 4.6 Secondary Clarifiers The Grassy Branch WRF has two 10 foot diameter secondary clarifiers. Each clarifier has a sidewater depth of 10 feet. The reported historical peak day surface overflow rates (SOR) and surface loading rates (SLR) are 1,823 gpd/SF and 63 lb/SF, respectively. The calculated overflow and loading rates are excessive compared to standard engineering best practices. Typical design overflow rates range from 300 to 1,000 gpd/SF. Typical solids loading rates range from 15 to 35 lb/day-SF. The existing secondary Engincer Certification for Grassy Rranch Water Reclamation Facility Page 6 of 9 clarifiers are undersized and caimot be further optimized. New secondary clarification capacity is required for the proposed improvements. 4.7 Tertiary Filtration The WRF has two mixed media (anthracite/sand) tertiary filters each with a surface area of 18.75 SF. The historic peak day hydraulic loading rate and solids loading rate are 7.3 gpm/SF and 3.9 lb/SF, respectively. The calculated hydraulic and solids loading rates are excessive compared to standard engineering best practices. Typical filter design hydraulic and solids loading rates are 5 gpd/SF and 3 lb/day-SF, respectively. The existing mixed media filters cannot be further optimized. New filtration capacity is required for the proposed improvements. 4.8 UV Disinfection The existing UV disinfection system was installed in the original chlorine contact chamber as a retrofit project. Routine maintenance is problematic as it requires that UCPW staff remove grating and stand in the channel. The existing UV system carmot be further optimized and does not have the required capacity to meet the proposed maximum month design flow. An additional unit(s) will be required to meet the proposed peak day flow. 4.9 Effluent Flow Measurement Effluent flow is measured via a discharge weir. The existing weir will require replacement to accommodate the proposed maximum month design flow. 4.10 Post Aeration The facility does not have a formal post aeration system. Aeration is achieved through the effluent flow weir and head drop to the final effluent discharge location. The facility has not had any effluent permit violations for dissolved oxygen, so it is not anticipated that additional post aeration capacity will be needed. 4.11 Aerobic Digester The existing aerobic digester equalization consists of two 4,500-gallon basins for 9,000 gallons of total volume. The aerobic digester is equipped with coarse bubble diffusers connected to the secondary treatment positive displacement blowers. The aerobically digested solids are pumped out and transported to the Crooked Creek WRF for final disposal. Additional aerobic digestion volume will be needed to accommodate the proposed maximum design flow. The final disposal method will not be altered. Engineer Certikeation for Grassy Branch Water Reclamation Facility Page 7 of 9 4.12 Operational Procedures Current operating procedures are consistent with best practices for operation of a wastewater treatment facility. Housekeeping and maintenance of the facility are excellent for industry standards. No operational changes are recommended at this time. 5. Specific Requirements of the SOC 5.1 Evaluation of Existing Treatment Units and Operational Procedures The existing Grassy Branch WRF does not have adequate process capacity to adequately treat the current flows and loads and maintain NPDES permit compliance. The WRF cannot be further optimized or operated in a manner that achieves compliance with final effluent permit limits. Additional process units are necessary to be in compliance with the existing final effluent permit limits. 5.2 The Effluent Limits that the Facility Could Be Expected to Meet if Operated at Their Maximum Efficiency during the Term of the Requested SOC (Consider Interim Construction Phases) The historical data indicate influent flows greater than the permitted maximum month design flow results in final effluent permit violations for flow, BOD, TSS, ammonia, and fecal coliform. Table 5-1 summarizes the requested interim effluent limits for the Grassy Branch WRF. The requested limits are based on the 2015 to 2018 historical data in conjunction with the process modeling and WRF evaluation. It is not anticipated that construction phases will be applicable to the proposed upgrade project, so tiered interim limits are not necessary.

A Phase 1 I&I study was commissioned in 2016 to broadly determine problem areas. A Phase 2 Engineer Certification for Gassy Branch Water Reclamation Facility Page K of9 study in 2017 focused on repair efforts readily identified in the Phase 1 study. The Phase 2 study also included wet weather monitoring. In 2018, Phase 3 efforts included confirming the effectiveness of previous repair efforts, extensive CCTV review of the entire collection system, and the continuation of repair efforts. Phase 4 of the I&I reduction effort started in 2019. This phase consists of a review of dry and wet weather data and patterns and on -going inspection of the collection system. As of January 2019, the entire Grassy collection system has been surveyed by CCTV. As of May 2019, 42 manholes have been grouted and 48 inflow collectors installed. Union County has also been actively evaluating process changes at the WRF to minimize NOW Staff has taken several precautionary measures in anticipation of high flow events, as follows: Bypassing of filters Increased monitoring of WRF to include frequent visits during a wet weather event and constant monitoring of telemetry via SCADA Control of air input to aeration basins to retain suspended solids: o Shutting down of all compressors except one. o Reducing remaining compressor to 30 Hz. o Shutting down all aerator drop legs except the first set. 6. Summary of Recommendations for Infrastructure Improvements The historical data indicate the influent flows that exceed the permitted design capacity of the Grassy Branch WRF have resulted in final effluent permit violations for flow, conventional pollutants, and bacterial pollutants. The County has attributed the majority of the NOVs to record rainfall events in the region. The County also acknowledges that more sewer connections have been allocated to the Grassy Branch WRF than available capacity. Hazen recommends a permanent increase in the design maximum month flow from 0.05 mgd to 0.120 mgd. Hazen recommends an expansion of the Grassy Branch WRF which would include larger influent pumps, an additional secondary treatment train and secondary clarifier, the addition of cloth disk filters, and a new UV disinfection system. Hydraulics would be evaluated during detail design. Existing unit processes will remain in service during construction. It is not anticipated that construction activity will affect the current facility performance.
