Please note that modifications to the Dedicated Reclaimed Water Utilization facilities require an additional form (i.e., Form RWNC 06-16). B. Cover Letter: 1. No comment. C. Application Fee: 1. No comment. D. Application: 1. The provided application was signed by Mr. Brandon Long, who is described as the facility’s Operator in Responsible Charge (ORC). Our office could not find documentation that the current ORC has delegated signature authority. Please provide the signature delegation authority letter (i.e., Form NDSDAL 01-20 attached) for Mr. Brandon Long. Please note that the individual delegating authority must meet the requirements of 15A NCAC 02T .0106(b) and .0106(c). 2. Please confirm that Mr. Brandon Long (ORC) is the individual listed as Mr. Charles B. Long (WW- 2 1000788; SI 991385). 3. Section IV.7 of the application indicates that a flow reduction has been approved under 15A NCAC 02T .0114(f). Please submit a copy of the flow reduction approval letter. 4. Section V.4 lists an overflow from the 5-day upset pond to the wet weather storage pond. Water held within the 5-day upset pond is considered off-specification and this overflow would result in partially treated water being introduced to the finished reclaimed water stored in the wet weather pond. Pursuant to 15A NCAC 02U .0402(g), by-pass and overflow lines shall be prohibited. Please provide additional information regarding the overflow identified in the application. 5. The response to Section V.8 discussing the number days of residual storage provided in the design was left blank. Pursuant to 15A NCAC 02U .0402(j), 30 days of residual storage shall be provided. Please provide additional information indicating the number of days of storage incorporated into the design and how the requirements of 02U .0402(j) are to be met. 6. Within Section V.11., and the included engineering documents, the proposed treatment appear to comprise a single treatment train. Pursuant to 15A NCAC 02U .0402(c), dual facilities are to be provided for all essential treatment units. Additionally, the 5-day upset pond must have the ability to return effluent to the head of the treatment facility in accordance with 15A NCAC 02U .0402(d). Please review and revise as needed. Mr. Brandon Long November 4, 2022 Page 3 of 6 7. Section V.11.e. lists the facility design criteria for pumps. The proposed grinder pumps to handle waste flow from the existing office restroom (as depicted on Sheet U-1) are not included in this table. This permit includes the wastewater collection system for the Trump National Golf Club Charlotte WWTP, and any modifications to the wastewater collection system should be included herein. Please note that modifications to the collection system must meet the requirements of 15A NCAC 02T .0300, the North Carolina’s Minimum Design Criteria for the Permitting of Gravity Sewers, and the Minimum Design Criteria for the Permitting of Pump Stations and Force Mains. Please review and revise as needed. 8. The permitted dedicated reclaimed water utilization system employs both spray irrigation and drip irrigation equipment. Within Section VII.8. only the drip irrigation design elements were provided. Please provide information on both the spray irrigation design elements and drip irrigation design elements. E. Property Ownership Documentation: 1. No comment. F. Soil Evaluation: 1. Not applicable. G. Agronomist Evaluation: 1. Not applicable. H. Hydrogeologic Report: 1. Not applicable. I. Water Balance: 1. Not applicable. J. Engineering Plans: 1. The resolution on the provided plan sheets is limited and many of the line-weights and hatches are distorted and illegible. In addition to uploading a copy of the revised plans with the response submittal, please provide an electronic copy of the plan sheets in a separate email for our review. 2. Within the Engineering Plans, the existing facility is only referred to in a call-out on Sheet U-1. Please provide a Demolition sheet identifying existing structures/units and piping to be removed and/or abandoned in place for our consideration. Please clarify what “to be abandoned” entails. 3. “Future” Flow Equalization (EQ) Basin and Textile Filter units are called out on Sheet U-1. Are these units for a planned capacity expansion? Please note that the 02U rules require all essential treatment units be provided in duplicate prior to start-up and operation. Please provide clarification and revise as needed to meet the requirements of 15A NCAC 02U .0402(c). Mr. Brandon Long November 4, 2022 Page 4 of 6 4. Proposed piping between the new treatment facility and the existing storage facilities (i.e., the 5- day Lined Upset Pond and the Wet Weather Lined Storage Pond) was not depicted on the plan sheets. Please review and revise the plan sheets as needed. 5. A profile was not provided for the proposed collection serving the office restroom. Please provide a profile and the necessary detail drawings, notes, and call-outs required by North Carolina’s Minimum Design Criteria for the Permitting of Gravity Sewers and the Minimum Design Criteria for the Permitting of Pump Stations and Force Mains. 6. Using the provided graphic scale, only 5 feet of separation exists between the proposed Flow EQ Basin #1 and the existing 5-day Lined Upset Pond. It is unclear what protections are going to be in place, and whether any additional considerations are needed for the proposed construction. Please provide additional information regarding the installation of this unit. 7. Per Sheet U-1, is the manhole receiving waste flow from the office restroom an existing or new structure? Please provide additional information. 8. The provided hydraulic profile on Sheet U-2 does not depict the 5-day upset pond and the wet weather storage pond. Please include these features and their associated elevations in the profile. 9. Sheet U-3 depicts an alkalinity feed line with a note stating, “If needed”. A project narrative for the proposed treatment process and engineering calculations were not included in the submittal, and it is unclear whether the alkalinity feed line is being proposed for installation. Please review and revise. 10. The trenching detail provided does not specify minimum cover, please revise the plan sheets to indicate a minimum cover for all influent and reclaimed water piping. 11. The plan sheets show that the proposed flow equalization basin is to be installed above-grade. Will above-grade piping and associated appurtenances be insulated to protect against freezing? Please provide a call-out, notes, or detail drawings related to above-grade piping. 12. Within the turbidity basin detail drawing, the piping depicted is generic and does not depict separate piping for the 5-day upset pond and the wet weather storage pond. Please review and revise the plan sheets as needed to show that the requirements of 15A NCAC 02U .0402(d) are being met. K. Specifications: 1. The specification package states that the system is designed to comply with North Carolina Administrative Code 15A NCAC 02H .0200 on Pages 1 and 2. These rules were repealed in place of the new 15A NCAC 02T rules in 2006. However, the facilities in this permit are regulated as a reclaimed water system under the 15A NCAC 02U rules. Please amend these sections to reference the applicable administrative code. 2. Within the Scope of the Project on Page 1, it is noted that during the construction process, the Owner is prepared to shut down all flow for a period to allow for the change to occur. However, it was not clarified how this will be accomplished. Please provide a construction sequence for this project that addresses how wastewater service will be handled during installation activities that interrupt the treatment facilities. 3. The Basis of Design in Section 3 of the specifications appears to have some inconsistencies with the engineering plans and application. The primary treatment units specify two AX-MAX units on Page 3, whereas only one unit is depicted on Sheet U-1 of the plans, with a second to be included Mr. Brandon Long November 4, 2022 Page 5 of 6 in the future. Similarly, there are only two ultraviolet (UV) units listed on Sheet U-1 of the plans and Page 3 of the specifications, but four are specified in parallel on Page 1 of the specifications. Please provide a clarification on how many units of each type are being proposed in this modification. 4. Of Page 3, the effluent sampling is mentioned as being a brass sillcock “Located at Headworks”. Please clarify where the representative effluent sample is to be collected. 5. On page 11 of the specifications, the panel operations mention that once the daily volume is reached for irrigation Fields A, B, and C, all effluent shall be sent to the offsite remote dosing tank. The fields in this permit do not include Fields A through C, nor is there an offsite remote dosing tank in the facility description. Similarly on Page 12, there is a reference to Sheet U-17 for details for a freestanding shelter for the control panel, but U-17 and the detail are not included in this application package. Please correct these sections. 6. See Item D.6. The System Controller section of the Control Panels and Electrical specifications shall include panel operation conditions to direct flow to the 5-Day Upset Pond if either turbidity or permitted pathogen levels cannot be met in accordance with 15A NCAC 02U .0402(d). 7. See Item D.7. Any specifications regarding the installation of the grinder pump shall be included in an updated specifications package if it is a part of the modification. This should include the manufacturer’s information for the unit, methods of installation, and any water level float controls/alarms that would be associated with this unit. 8. See Item J.2. Please provide specifications detailing demolition procedures to be used for the removal/abandonment of any existing facilities. 9. See Item J.4. Please provide specifications for the installation of new piping, such as trenching and backfilling. 10. Specifications shall be provided detailing any provisions or considerations that are to be used protect the integrity of the existing facility. This should include protections such as stormwater/sediment control and construction techniques to preserve the integrity of the liner for the existing 5-Day Upset Pond during construction activities (mentioned in Item J.6). 11. See Item J.11. Specifications shall be provided detailing any provisions or considerations to be used to protect against freezing of pipes and associated appurtenances. L.
