Overall 1. The Applicant's responses to the questions regarding dual facilities (i.e., Item D.6 in the Response Letter dated December 21, 2022, and Item VI.8 of Application Form RWG 06-16) indicate that mechanical redundancy is to be provided in lieu of dual facilities. Mechanical redundancy is required under 15A NCAC 02U .0402(h) where "multiple pumps shall be provided wherever pumps are used". Pursuant to 15A NCAC 02U .0402(c), dual facilities shall be provided for all essential treatment units. The intent of this rule is that reclaimed water facilities be designed with dual treatment trains for all essential treatment units. The combined capacity of the dual treatment trains must at least equal the proposed design treatment capacity of 25,000 gallons per day (GPD). Please revise the proposed design to meet the requirements of 15A NCAC 02U .0402(c). Based on actual daily flow to the treatment plant, we feel that Phase I (installed at this time) meets the intent of the rule with all essential treatment units including 2 times the volume in the flow EQ chamber, 2 rows of textile accounting for two times actual daily flow, dual pumps in all places, and two UV filters allowing for redundancy with all essential treatment components. 2. With regards to the permitted capacity of the TNGC Charlotte WWTP: a. The RWG 06-16 application lists a daily design flow of 25,000 GPD under Item 111.6. This value corresponds with the previously permitted treatment facility design. b. A review of the provided engineering calculations indicates that the current disposal capacity is 20,000 GPD (12,500 GPD contributed via spray utilization areas and 7,500 GPD contributed via drip utilization areas). c. The response to Item J.3. in the Response Letter dated December 21, 2022, indicates that the "future" treatment units depicted on the plans are necessary for the treatment facility to be rated at 25,000 GPD. However, pending the response to Item A.1, we understand that these "future" units are not proposed for construction currently resulting in a design treatment capacity of 12,500 GPD. Item A should be 20,000 GPD and has been revised to reflect that since the irrigation areas are the limiting factor in the design flow. Since the actual daily flows do not exceed 6,500 gallons per day, we request that the design flow remain at 20,000 GPD in the permit. If flow to the treatment plant were to increase from any new growth (none planned at this time) then Phase II would be required to be implemented per the newly requested permit. Please note that the permit effluent flow limit is based on the most restrictive capacity (treatment or disposal). If the proposed facility capacity (either treatment or disposal) is less than the minimum allowable daily design flow under 15A NCAC 02T .0114(c), then a Flow Reduction Approval from the Collections Group within the Municipal Permitting Unit may be necessary. Please contact the Collections Group regarding the requirements of 15A NCAC 02T .0114(f) for an adjusted daily sewage flow design rate. Please provide our office with a copy of the Flow Reduction Approval or other documentation indicating that the requirements outlined in 15A NCAC 02T .0114 are being met. This item was addressed on October 20, 2015 (see attached approval). 3. Within the Engineering Documents, Sheet U-3 depicts a single Flow EQ Tank, a Stage 1/Textile Filter Tank, a Stage 2/Polishing Filter Tank, and a greyed -out "Future" Stage 1/Textile Tank to be installed in parallel with the aforementioned Stage 1 Tank. On Page 4 of the Specifications, the components of the system list one Flow EQ Tank, two Stage 1/Textile Filters, and one Stage 2/Polishing Filter. On Page 17 of the Specifications, the system components are listed as two Flow EQ Tanks, two Stage 1/Textile Filter Tanks, and one Stage 2/Polishing Filter Tank. Are both Flow EQ Tanks and Stage 1/Textile Filter Tanks being proposed for construction in this modification? It is unclear whether the Applicant is seeking to have all the depicted units (including the greyed out "Future" units) permitted as part of this modification request. Please provide clarification and ensure that the Plan Set and the Specifications agree. This was clarified on page 17 of the specification section that (1) flow equalization tank, (1) primary recirculating textile filter and (1) Stage II recirculating textile filter is to be installed at this time. B. Response/Cover Letter: 1. The response to Item J.6. in the Response Letter dated December 21, 2022, indicates that the unit will be placed at grade; however, the response (and the specifications) was unclear on how the proposed Flow EQ Basin #1 (which is not an Orenco Media Filter) is to be maneuvered into place without damaging the liner of the 5-day upset pond. Additionally, it was noted that the proposed location for the Flow EQ Basin #1 crosses the existing return pipe from the 5-day upset pond to the treatment headworks. Will the existing return pipe be impaired by the installation of Flow EQ Basin #1? Please provide additional information regarding the installation method proposed for Flow EQ Basin #1 and any considerations being taken to ensure that the existing infrastructure associated with the 5-day upset pond remains operational. These considerations should be outlined within the Specifications. The flow equalization tank (TMAX) will be set on the existing grade and will remain above grade with no excavation required adjacent to the existing 5 day upset pond. Existing area will be leveled with gravel screenings (existing site material) to allow for a level pad for the unit to be placed on. 2. The response to Item KA indicates that a sampling port is to be located at the back of the last treatment unit before discharging to the turbidity basin. Sheet U-6 of the plans is referenced as the noted location. A review of Sheet U-6 depicting the polishing filter does not show an effluent sampling port. Please revise. This was added to Planview on plan sheet U-6. E. RWG 06-16 Application: 1. The values provided in the table for Item V.1. appear to be directly copied from the Type 1 reclaimed water effluent characteristics in 15A NCAC 02U .0301. These values should reflect what the proposed treatment facility can achieve based on the engineering calculations. Please revise Item V.1. The values have been revised to reflect the calculations provided by the manufacturer. 2. Within Item Vll.d. Residuals Treatment, an anaerobic digester is listed. An anaerobic digester is not described within the remaining engineering documents. Please clarify why an anaerobic digester is specified here. This was an error on our end with the pull -down menu on the application. The application has been revised accordingly for Residuals Treatment to be as "other". All solids are removed from the waste at the TMAX unit, which acts like a septic tank, so that only effluent is treated in Stage I and Stage II filters. F. RWNC 06-16 Application: 1. Item 1.4 of the lists a dedicated utilization capacity of 25,000 GPD for the TNGC Charlotte WWTP. In Item 11.6., the applicant indicated that this value is based on what was listed in the previous permit. The engineering calculations provided in this submittal determined that 5,000 GPD of capacity associated with drip zones D-4, D-5, D-6, and D-7 was removed from the permit in 2015. The combined disposal capacity in the calculations lists 12,500 GPD attributed to the spray utilization sites and 7,500 GPD attributed to the remaining drip utilization sites for a total disposal capacity of 20,000 GPD. Additionally, a note within Section VI. Design Information for Non -Conjunctive Irrigation Systems indicates that the spray system is not utilized. Is the active dedicated utilization capacity currently 7,500 GPD? Please document the disposal capacity and revise the application. Additionally, please explain why the spray utilization system is currently not in use and if repairs are necessary to return the spray utilization sites to operational status. Additional supporting documentation (i.e., soils report, agronomic evaluation, hydrogeologic report) in favor of the 25,000 GPD disposal capacity for the remaining utilization sites may be necessary. You are correct that the drip field removal permitted in 2015 was for 5,000 gallons per day, therefore, the permitted design flow has been revised from 25,000 gallons per day to 20,000 gallons per day. The daily flow never exceeds 6,500 gallons per day of actual flows. The drip is utilized first, then the spray irrigation. The spray system is manually operated periodically by the ORC as demonstrated to Maria Schulte at MRO at time of last inspection and performed satisfactorily. No additional flow is expected to be added to the WWTP, however, the client does not want to revise permit for any less flow than what is currently permitted. H. Engineering Plans: 1. Sheet DEMO-1 indicates the intent is to cut and cap the existing treated effluent piping to the old plant; however, it is unclear what is being proposed for the abandonment/removal of the existing return pipe from the 5-day upset pond to the old plant or the inlet piping from the old plant to the 5-day upset pond. The specifications within the Demolition section state that all underground piping may remain at the discretion of the Owner. Please provide additional information. The intention of the return pipe from the 5-day upset pond to the old plant is for it to be re-routed to the head of the new plant. 2. Sheet U-6 depicts an AX-MAX 125-42 Denite Unit. This differs from what is listed on Sheet U-3 for Stage 2 (an AX-MAX 275-42 unit). Which AX-MAX unit is being proposed for Stage 2? Please revise the Plan Sheets, as necessary. This treatment unit was revised on the plans as noted. 3. Piping from the 5-day upset pond to the head of the treatment works was not depicted. Please revise Sheet U-1 to depict all the proposed piping and accompanying inlet/outlet structures. Will the pond levels need to be lowered to complete this work? Revised as requested. Pond levels will not need to be lowered to complete the conversion of the return piping to from 5 day upset to the old plant to the new plant. 4. The provided plan set dated April 12, 1999, depicts the discharge piping from the treatment facility to the 5- day upset pond at the southern corner with a similar configuration at the southeastern corner of the wet weather storage pond. The proposed treatment configuration depicts discharge piping into the northern corner of the 5-day upset pond with a similar depiction at the southwestern corner of the wet weather storage pond. Detail drawings for the discharge piping/structure were not provided for the proposed treatment configuration. Detail piping now shows tying into these existing discharge pipes from the existing plant so that no penetrations into the existing liners would be made. This was discussed with the ORC and installer and Mr. Long felt this was the best way to do this. 5. The provided plan set dated April 12, 1999, depicts a 6-inch perforated PVC pond underdrain that runs down the centerlines of the 5-day upset and wet weather storage ponds. Where does this subsurface drain discharge? This existing subsurface drain discharges below Irrigation Zone 1 into an existing storm drain junction box per the current and previous ORC. I. Specifications: 1. Page 1 of the specifications indicated that the 5-day upset pond and wet weather storage pond are to be unchanged. Specifications were not provided regarding the installation of the revised piping and inlet/outlet structures within the 5-day upset pond and wet weather storage pond. Means and methods for ensuring that the integrity of the synthetic liner is not compromised should be described. There will no new pipe penetrations in the existing pond liners. It was discussed with the current ORC, Brandon Long as well as the previous ORC, Tim Bannister, that the existing 4-inch metal pipe will be tied into on the eastern side of the upset pond to avoid cutting into the existing liner. J. Engineering Calculations: 1. The provided engineering calculations are considered incomplete. Pursuant to 15A NCAC 02U .0201(c)(3), treatment unit sizing criteria (including UV disinfection systems), total dynamic head and system curve analysis for each pump and buoyancy calculations are to be provided. Please revise. All calculations have been provided as requested. As far as the treatment unit are concerned with buoyancy calculations, these are not needed since they will be set on grade or cut into bank. 2. The facility capacity varies throughout the calculations package. The initial page of the Piedmont Design Associates calculations shows a maximum daily flow of 12,500 GPD, and the second page shows a maximum daily flow of 25,000 GPD. The first page of the AQWA calculations shows an average flow of 9,500 GPD, and the second page shows 14,750 GPD. Please clarify the proposed treatment capacity, and if construction is to be conducted in phases, then please clarify Phase 1, 2, etc. within the calculations and the other engineering documents. Please also explain the discrepancy between the Piedmont Design Associates design flows and the AQWA design flows. The design flow we are using for the treatment and disposal system is 20,000 gallons per day due the restricting daily flow of the irrigation fields. The daily maximum flow to the system never exceeds 6,500 gallons (based on actual data). 3. The required textile area of 531 square feet (SF) at a flow of 9,500 GPD provided by AQWA does not appear to correspond to the Piedmont Design Associates 12,500 GPD textile area calculation which states that 250 SF of AX-MAX textile is required with an additional 65 SF of textile (having a different textile per unit value of 75 SF) listed for polishing. Is the Piedmont Design Associates calculation describing an AX-MAX 275-42 unit and an AX-MAX 125-42 Denite unit? Is the proposed design of one AX-MAX 275-42 unit against the manufacturer's specifications, and is the single unit sufficient to meet the effluent treatment standards for 12,500 GPD? A portion of the calculations that were provided were used in the preliminary sizing of the treatment units. These have been removed from the calculation section of the submittal. The new calculations have been revised to reflect a design flow of 10,000 gallons for Phase I and 20,000 gallons for Phase II. 4. Similarly, a large discrepancy between the required textile surface area is present between the AQWA and Piedmont Design Associates calculations for the proposed permitted flow of 25,000 GPD. The AQWA calculation determined that 824 SF (equivalent to three AX-MAX 275-42 units) is necessary for a lower design flow (14,750 GPD). The calculations provided by Piedmont Design Associates showed that treatment is achieved with 500 SF of textile (two AX-MAX 275-42 units) and an additional 125 SF of textile (possibly as one AX-MAX 125-42 Denite Unit). Please address this discrepancy and clarify the design and unit selection. If the AX-MAX 125-42 unit is not being proposed, then please revise the calculations from Piedmont Design Associates to reflect the designed treatment facility. A portion of the calculations that were provided were used in the preliminary sizing of the treatment units. These have been removed from the calculation section of the submittal. The new calculations have been revised to reflect a design flow of 10,000 gallons for Phase I and 20,000 gallons for Phase II. 5. Within the calculations for the high-water alarm elevation, a total dosage of 27,000 GPD is used. Our understanding is that the applicant is proposing a facility capacity of 25,000 GPD, please explain what the additional 2,000 GPD represents in this calculation. Total volume dosed over the Advantex Textile filter has been revised to be 20,000 gallons, however, based on historical data, the treatment and disposal system will never see volumes of this magnitude. The high — water alarm will remain at 4.05-inches above the tank bottom. O. Recommendations: 1. Based on the submitted design, the turbidimeter and diversion to the 5-day upset pond occurs downstream of the UV disinfection unit. The UV disinfection system experiences reduced efficacy under increased turbidity conditions, and it is unclear how the proposed configuration will prevent solids accumulation in the UV bank. Our office recommends the Engineer consider altering the design such that the turbidimeter and diversion process occurs prior to the UV disinfection chamber. The turbidimeter has been re -located to the outlet side of the Stage II Polishing Filter (pre -UV) as recommended after discussions with the ORC and treatment manufacturer. We feel this addresses all concerns regarding this project. If you have any further questions, comments or concerns, please feel free to contact us at (704) 664-7888.

Suite 101 Westfield Center 125 East Plaza Drive Mooresville, NC 28115 Phone: (704) 664-7888 NCBELS: C-1007 SECTION I - GENERAL Trump National Golf Course is a private golf course and club located in Mooresville, Iredell County, North Carolina. Trump National Golf Course was originally permitting for installation and operation around 2000 by Dale Stewart, PE with Land Design. Based on historical usage, a modification to the irrigation fields was applied for in 2015 to allow for a portion of the drip irrigation wetted areas to be removed from the permitted areas. Due the age of the current wastewater treatment plant and the ongoing operation and maintenance costs, the Current Owner & Operator (TCW Wastewater Management, Inc.) have decided to abandon the existing treatment facility and install a new treatment system on the same site, treating to the same standards. The current collection system, 5 day upset pond, wet weather storage pond and disposal system will not change. All solid waste will be collected at the front end of the treatment system and pumped on an as needed basis. Residuals will be disposed of offsite by a licensed pumper. Directions to the property: From Brawley School Road in Mooresville, travel southwest toward the end of the road. Go around the traffic circle. Treatment area is located on left hand side of the road. These specifications and design plans have been prepared for a centralized treatment and disposal system. The system will consist of two Orenco T-MAX 42 Unit (septic tank chamber and flow equalization chamber) with alternating duplex pumps (one Phase I current & one Phase II future) for (25% of the peak daily flow), (2) Orenco AX-MAX 275-42 recirculating textile media filters in parallel (one Phase I current & one Phase II future), a secondary (Stage II) Orenco AX-MAX 275-42 recirculating textile media filter with turbidimeter located in back end of unit and UV filtration located after unit. Treated effluent passes through (2) UV disinfection units in parallel, an existing lined wet weather storage impoundment, an existing lined upset pond will remain unchanged. Irrigation fields will be dosed out of an existing 4-foot diameter wet well with duplex alternating pumping system. Treated effluent will pass through existing filtration to screen -out fine material prior irrigation to the wetted areas. All irrigation components, including dosing sequence will remain unchanged. The system is designed to accept and treat waste from the commercial portion of Trump National Golf Course. No other discharge is allowed, including condensate water from HVAC systems and stormwater. The systems design criteria are intended to comply with NC DEM Administrative Code 15A NCAC 2H.0200 and 15A NCAC 18A .1969 and IWWS-2004-3-R4 (Orenco Treatment Systems). The installer shall be knowledgeable of the type of system to be installed and shall have prior instruction on the installation of the various components of the system and shall have the prior approval of the treatment manufacturer (Orenco), and the approval of the Design Engineer. Scope of the Project: The scope of this project is to abandon the current wastewater treatment process and install new process. The existing collection system will remain unchanged as well as upset, wet weather storage and the irrigation system. The new process will include a vessel to remove solid on the front end of the treatment process, flow equalize the effluent and treat for disposal. Since the new treatment process will be placed in an area where there are no treatment components, transition plans are to install a valve on the existing plant influent force main adjacent to a new tee and a new valve toward the new plant as shown on the plans. Once the new plant has been accepted by all parties and tested, the valve to the old plant can be closed and new valve can be opened. This valve and tee assembly can be cut in and can occur during non -operational hours once the new installation is close to completion. The new pump controls will have a 24-hour clock, programmable as determined by the Engineer and the Operator. Controls shall also have elapsed run time clock and cycle counter for each of the pumps. The controls shall also have manual operating capabilities and alarms. The controls are to be placed in a readily accessible location at the facility.

Freeze Protection for Above Ground Piping PVC and CPVC piping systems are susceptible to freezing in colder temperatures. There are several operational and installation practices that can be used to protect the system from freezing such as using pipe insulation and heat trace tapes. The manufacturers of these products should be consulted for suitability and compatibility with PVC and CPVC prior to use. Acceptable forms of insulation shall be either a tubular foam rated for exterior use or a fiberglass pipe wrap with a self-sealing jacket. Other methods are approved on a case -by -case basis approved by the Engineer. PVC and CPVC piping systems installed in direct sunlight or in enclosed boxes, primarily metal, should have precautions taken to ensure that the environmental conditions do not exceed the temperature ratings of the material. Failure to do so can result in product/system damage and/or failure. PVC and CPVC piping systems exposed to direct sunlight (UV radiation) can be painted with a light-colored acrylic or latex (water -based) paint to avoid UV radiation, and its effects. Dark colors can lead to greater heat absorption, which can exceed the heat handling capacity of the fittings and pipe material. Design and installation considerations for thermal expansion/contraction should still be made. Check with the paint manufacturer to assure the paint is chemically compatible with the PVC/CPVC products. Use only water - based paints. Oil -based paints are not recommended for use with PVC or CPVC. Requirements for Leakage Testing -Pressure PVC Piping Required testing of pipelines and valves shall be done under the direct supervision of the Project Engineer. Field-testing shall not negate the requirements for material certifications as contained in the material specification section of this contract. Unless otherwise directed by the Engineer, all testing and disinfection will be completed prior to connection to any existing line.

The water for testing purposes can be taken from the nearest available water source under the supervision of the Engineer's Inspector. All leaks and any defective material shall be repaired or replaced to the satisfaction of the Engineer and the tests repeated until the requirements of this specification are met. Any special equipment, pumps, etc., required to make the test shall be furnished and operated by the Contractor as directed by the Inspector. The Contractor shall use great care to be sure that all air is expelled from each section under test. If service connection or other openings are not available for the purposes of expelling air, the Contractor shall provide air release of sufficient size (as determined by the Engineer). Trump National Golf Course WWTF Page 15 June 16, 2022 Mooresville, Iredell County, NC Revised December 21, 2022 Revised April 3, 2023 Specific procedures for testing main are as follows: • The test pressure will be 100 PSI at the low point of the section under test. • Allowable leakage will be determined by Table 6, AWWA C-600 (see below) or by the formula: 1 = 0.000106(S)(D) where S in the length of pipe under test and D is the pipe diameter. • Pressure and leakage tests will be run concurrently and for duration of four hours except as modified below. • The Contractor will pressurize the line and verify that it is within allowable leakage before the official test is started. • The Inspector will begin the test and remain at the job for the first hour, making sure that the test pressure is maintained within 5 PSI. The Contractor is to maintain the pressure within 5 PSI for the duration of the test period. At the end of the first hour, with the line pumped to full test pressure, he will read the meter and record the first hour leakage. If the first hour leakage is within allowable, he will return at the end of the fourth hour and again read the meter. If the total leakage for the four-hour period does not exceed four times the first hour leakage, the test will be terminated. If the total leakage exceeds four times the first hour leakage, but is still within allowable, the test will be held an additional hour. If the fifth hour leakage does not exceed the average hourly leakage for the first four hours, the test will be terminated at the end of the fifth hour. Otherwise, the test will be held until the leakage is non -increasing and within allowable for two consecutive hours. • If leakage exceeds allowable for the four-hour test, the test will be terminated and re -scheduled after the Contractor has verified that actual leakage is within the allowable leakage, but no earlier than the next working day. • If the first hour leakage does not exceed 15% of the allowable, or if the allowable leakage rate does not exceed 0.4/gal/hr., the test may be terminated at the end of two hours provided the second hour leakage does not exceed the first hour leakage. If the second hour leakage exceeds the first hour leakage, the test will be held for an additional period as described in Paragraph (e) above. • The maximum length of pipe testing in one test shall be 5,000 feet or as close to 5,000 feet as possible depending on valve spacing. • During the last stages of the test and without any reduction in pressure progressing from the end opposite the test pump, each mainline valve will be closed, and pressure released to determine if the valve is holding pressure (minimum 10 minutes per valve closing). The Contractor shall be required to provide as many tests and/or certifications as the Engineer may deem necessary for materials, such as concrete, piping, valves, steel reinforcement, all fasteners and anchorage systems, etc. Testing for materials shall be made by a separate independent test laboratory employed by the Contractor and approved by the Engineer.
