Sincerely, Lauren Raup-Plummer, Engineer III Division of Water Resources cc: Wilmington Regional Office, Water Quality Regional Operations Section (Electronic Copy) Jimmy Holland, PE – McKim & Creed, Inc. (Electronic Copy) Laserfiche File (Electronic Copy) Mr. Barnes Boykin August 12, 2022 Page 2 of 6 A. Cover Letter: 1. No comment. B. Application Fee: 1. No comment. C. Application: 1. In Section II, the provided address of 2844 Caratoke Highway and the provided facility coordinates of 34.44º, -78.05º do not appear to correspond to the parcel referenced in the submittal documents. Please revise the facility information to include the address associated with the proposed facility, and please revise the coordinates to a higher level of accuracy (preferred accuracy is to the nearest tenth of a second or six decimal points). 2. Item IV.7 lists that representative data and a flow reduction approval were used for the proposed facility’s wastewater flow. A value of 260 gallons per day (GPD) was listed for the business; however, it is unclear what data was used to determine this flow as this facility and the associated business have not yet been constructed. Additionally, a copy of the flow reduction approval letter was not included within the submittal package. Please provide additional information regarding the daily design flow of the proposed wastewater facility that meets the requirements of 15A NCAC 02T .0114(c) and a copy of the flow reduction approval letter issued by the Municipal: NPDES, Pretreatment and Collection Systems Unit. 3. Item IV.9 indicates that documentation of the presence or absence of threatened or endangered aquatic species was provided. This documentation was not included in the submittal package. Please provide the missing document. 4. Item IV.10 lists an active monitoring well (Monitoring Well 1). Please provide a copy of the Well Construction Record (Form GW-1) so that we can add this well to the permit records. If the well has not been constructed, then please revise the application to indicate that the monitoring well is “proposed”. 5. Item V.1, the “Designed Effluent Concentrations” column lists values of less than the permit limits outlined in 15A NCAC 02T .0505 for the designed effluent parameter rather than supplying values representative of the proposed plant’s nutrient and constituent removal capacity. Please provide either removal calculations that demonstrate what this treatment facility should be capable of achieving or effluent study data from Advantex systems serving comparable influent waste streams. Please revise the application as needed. 6. The response to Item V.5 states that an activated standby power supply will be made available onsite to satisfy 15A NCAC 02T .0505(l). The response under Item IX.5 indicates that an automatically activated standby power source will not be provided. Please address this discrepancy and provide additional information regarding the Power Reliability Plan. 7. Earlier in the application, it was indicated that 15A NCAC 02T .0505(k), which requires multiple pumps be provided wherever pumps are used, is being met. Section V.11.e indicates that only one effluent pump is being installed in the pump tank. How is the applicant intending on complying with .0505(k)? Mr. Barnes Boykin August 12, 2022 Page 3 of 6 8. Item VII.1 of the application states that the minimum depth to the Seasonal High Water Table (SHWT) within the proposed irrigation area is 2.72 feet. This measurement does not appear to agree with the Soil Evaluation report provided by Applied Resource Management, P.C. which indicated that the water table may be within 12 inches of the surface. Please revise or explain the discrepancy. D. Property Ownership Documentation: 1. The submittal package included a document titled “Assignment of Rents” between Cedar Run Capital, LLC (the applicant) and Truist Bank that refers to parcel 2285-63-0939-0000. The "Assignment of Rents" document does not appear to meet the requirements of 15A NCAC 02T .0504(f), and a review of the Pender County Register of Deeds GIS map shows that Parcel number 2285-63-0939-0000 is owned by Rudy Johnson. Additionally, Mr. Johnson does not appear to be affiliated with Cedar Run Capital, LLC. Please demonstrate that the requirements of 15A NCAC 02T .0504(f) are being met by providing one of the following: a) Legal documentation of ownership (i.e., GIS, deed or article of incorporation), b) Written notarized intent to purchase agreement signed by both parties with a plat or survey map, or c) Written notarized lease agreement that specifically indicates the intended use of the property and has been signed by both parties, as well as a plat or survey map. Lease agreements shall adhere to the requirements of 15A NCAC 02L .0107. E. Soil Evaluation: 1. Saturated hydraulic conductivity (Ksat) values were only provided for depths of 22 to 40 inches and 66 to 84 inches. The Murville Muck series, as described in the “Soil Survey of Pender County, North Carolina”, includes a mucky fine sand in the A horizon. The provided engineering design indicates that the existing soils are to remain in situ, and hydraulic conductivities were not provided for the full soil profile. Indications of a shallow groundwater table were noted throughout the Soil Evaluation, and it is unclear whether the values depicted in Table 1 are representative of the most restrictive soil horizon at the site. Please provide additional information regarding the saturated hydraulic conductivity in the upper 22 inches of the soil profile. 2. Within the Soil Evaluation, a maximum daily design flow of 200 gallons per day (GPD) is provided based on the preliminary water balance data with a note that the maximum daily design flow may be limited by nutrient loading rather than hydraulic loading. The loading rate analysis section indicates that phosphorus removal is the limiting design criteria and provides a maximum loading rate of 70.8 inches per year. The loading rate of 70.8 inches per year for a 0.08-acre disposal area appears to correspond to approximately 420 GPD – this is reflected in the Daily Design Flow calculation in Appendix B. The engineering design for this application uses a daily design flow of 260 GPD. It is unclear what the basis is for the 200 GPD recommended in the Soil Evaluation, and whether the proposed engineering design daily flow of 260 GPD is attainable for the current site conditions. Please address the inconsistencies between the daily design flow requirements and provide additional information as needed. F. Agronomist Evaluation: 1. No comment. Mr. Barnes Boykin August 12, 2022 Page 4 of 6 G. Hydrogeologic Report: 1. Not applicable. H. Water Balance: 1. The provided water balance was termed a “Quick Water Balance Assuming No Storage”. It is unclear how nutrient management, required pursuant to 15A NCAC 02T .0504(k), has been incorporated into the provided water balance. The maximum allowable irrigation depicted shows considerably higher values than the 259 gallons per day listed in the Totals row. Please provide additional information regarding the water balance. I. Engineering Plans: 1. The provided Plan Set appears to have been resized during the submittal process rendering many of the finer notes and features illegible. Please submit a copy of the revised Plan Set via email in addition to your electronic submittal for the response to this letter so that our staff can confirm that the depicted facility corresponds to the provided engineering calculations and design.. 2. Several of the submitted documents indicated that Irrigation Field Notes 1 and 2 on Sheet G101 conflict with the Fill System Detail provided in the Soil Evaluation report. The Fill System Detail calls for 24 inches of approved sand fill, while the Plan Note calls for 18 inches. Similarly, the Fill System Detail states that fill material should be tapered from the top edge of the fill to the ground surface 6 feet from the boundary area, while the Plan Note calls for 5 feet. 3. Sheet C101 depicts a pond and a temporary skimmer basin near the proposed treatment plant and irrigation facility. The scale on the provided plan set is difficult to discern, but it appears that these features are within the setback limits outlined in 15A NCAC 02T .0506. The Soil Evaluation provided by Applied Resource Management, P.C., recommended reconstruction of the pond to provide for the proper setback distance; however, this does not appear to be reflected in the provided Plan Set (or other engineering documents). Additionally, it is unclear whether the temporary skimmer basin will still be in operation at the time of facility start-up. Please provide additional information regarding these structures including anticipated cease of operation, reconstruction, and any additional actions necessary to meet the setback requirements. 4. A sufficiently detailed view of the pump tank was not provided within the submitted Plan Set. Please include a detail that depicts the screened vent, as well as a depiction of the controls, alarms, and proper signage. 5. Please provide a trench detail for piping installation and a detail for the compliance monitoring well. Please note that monitoring wells are to be constructed in accordance with the 15A NCAC 02C rules. J. Specifications: 1. The Engineering Plans and Soil Evaluation indicate that specialized earthwork is needed to construct the drip irrigation area. Please provide specifications for the construction of the drip irrigation mound area, including the type of soil to be used as backfill, methods used to place the soil (e.g., tilling, discing, etc.), and any other necessary considerations. Mr. Barnes Boykin August 12, 2022 Page 5 of 6 2. On page TS-4, Subpart 1.09 Equipment states that the Contractor may use any type of earth- moving, compaction, and watering equipment. Additional considerations are required for earthwork and preparation activities in the proposed disposal area to preserve soil structure. Please revise this section to adequately reflect separate requirements for earthwork activities within the proposed disposal area. 3. Page TS-9 discusses fertilizer application in advance of seeding, but the specifications do not appear to distinguish between the drip irrigation areas and the landscape areas of the property. The proposed fertilizer is 8-8-8 which will result in further phosphorus loading to the proposed disposal area and is not suitable for a site where phosphorus removal is the limiting design criteria. Please revise this section to adequately reflect separate requirements for seeding and turfing the drip irrigation areas. The Non-Discharge Branch also requests that the proposed seed mixtures for the irrigation area cover crop be described therein. 4. TS-18 describes the high-head effluent pumps, but a few parameters were not included. Please include the proposed pump operating point. 5. The specifications for the disinfection system list only that it is to be accomplished by ultraviolet disinfection. Please provide details including the number of banks, the number of lamps per bank, and the maximum disinfection capacity. Please also include product sheets of the selected system or a list of acceptable manufacturers. K. Engineering Calculations: 1. Several calculations were not included in the submittal. Pursuant to 15A NCAC 02T .0504(c)(3), the engineering calculations should include hydraulic and pollutant loading for each treatment unit, treatment unit sizing criteria, hydraulic profile of the treatment system, total dynamic head, and system curve analysis for each pump, buoyancy calculations, and irrigation design. Please revise the calculations to include the hydraulic and pollutant loading for each treatment unit, treatment unit sizing criteria, the hydraulic profile of the treatment system, and the system curve analysis depicting the pump curve and operating point. L. Site Map: 1. It appears that Plan Sheet C101 is meant to serve as the Site Map for this permit application. This sheet was missing several of the features required under 15A NCAC 02T .0504(d). Please include the monitoring well (i.e., MW-1) and label the disposal zones (i.e., Zone 1 and Zone 2) so that the Site map corresponds with the information provided in the application form. Please revise as needed. M. Power Reliability Plan: 1. A Power Reliability Plan was not included in the submittal. On the application checklist, the checkbox for “Has sufficient storage capacity that no potential for overflow exists” is checked. A storage calculation was not provided within the submittal package, and further information is needed for approval from the Director. Please provide additional information within the Power Reliability Plan document that meets the requirements of 15A NCAC 02T .0505(l). Mr. Barnes Boykin August 12, 2022 Page 6 of 6 N. Operation & Maintenance Plan: 1. Pursuant to 15A NCAC 02T .0507(a)(4), the Operation & Maintenance (O&M) Plan shall include spill control provisions, including (but not limited to): response to upsets and bypasses, including control, containment, and remediation; and contact information for plant personnel, emergency responders, and regulatory agencies. 2. The Drip Irrigation System O&M Manual states "See the following pages for specific maintenance tasks and troubleshooting guidelines". However, no additional pages were provided. Please review and revise. 3. The ultraviolet (UV) disinfection system did not appear to be included within the provided product manuals. Please provide the appropriate Operation & Maintenance information for the proposed UV disinfection system. O. Residuals Management Plan: 1. A Residuals Management Plan was not included in the submittal. Pursuant to 15A NCAC 02T .0504(j) and .0508, submit a Residuals Management Plan that includes, at minimum: a. A detailed explanation of how generated residuals (including trash, sediment and grit) will be collected, handled, processed, stored, treated, and disposed. b. An evaluation of the treatment facility’s residuals storage requirements based upon the maximum anticipated residuals production rate and ability to remove residuals. c. A permit for residuals utilization or a written commitment to the Applicant from a Permittee of a Department approved residuals disposal/utilization program that has adequate permitted capacity to accept the residuals or has submitted a residuals/utilization program application. P. Additional Documentation:  Floodway Regulation Compliance: 1. Not applicable.  Operational Agreements: 1. No comment.  Threatened or Endangered Aquatic Species Documentation: 1. Appropriate documentation was not included in the submittal. Please provide documentation meeting the requirements of 15A NCAC 02T .0105(c)(10).
