J4 �‘�� July 27, 2022 ism Mr. Charles Weaver 7/zMon NPDES Permitting Program Division of Water Quality 1617 Mail Service Center Raleigh,North Carolina 27699-1617 RE: Application for Discharge System—Turning Point CDC 2495 US 1/158 Hwy N, Henderson,NC 27536 Dear Mr. Weaver, Enclosed please find information supporting an application for a Certification of Coverage under the General Discharge Permit. The application is for a wastewater system with a design flow of 765 gallons/day (domestic waste) for an existing daycare facility located in Henderson, North Carolina. The proposed system will replace an existing un-permittable sub-surface system that serves the property. The current system is located off of the property. The project is located in Vance County, North Carolina. The site has been deemed unsuitable for ground absorption sewage treatment systems by the Granville-Vance District Health Department due to unsuitable soil characteristics, unsuitable wetness conditions, unsuitable soil depth, and insufficient space for a primary and repair area. This application is being submitted with the intent to have coverage under the NCG550000 General Discharge Permit. The following information is included with this letter: Notice of Intent(NCG550000). Attachment A. $60 check payable to North Carolina DENR. Letter from Granville-Vance District Health Department. Attachment B. Letter requesting coverage under the General Discharge Permit. Attachment C. Letter requesting an Authorization to Construct. Attachment D. Soils Evaluation report by Chris McGee of AWT, Inc. Attachment E. Correspondence from USGS. Attachment F. Flow Path to"Blue Line" Water Feature.Attachment G. Information on Connecting to Regional Sewer. Attachment H. Engineering Alternatives Analysis (EAA).Attachment I. Local Government Review Forms. Attachment J. Plans and Specifications for the proposed system. Attachment K � J The proposed discharge point is in an existing pond located on the adjacent property to the north that discharges north into an existing tributary of Indian Creek. A drainage easement will be required for the adjacent property to the north of the subject property as is included in Attachment G. The discharge system will utilize the following components: Septic Tank with Effluent Filter - Recirculation Tank AdvanTex®Treatment Pods(2 Pods) UV Disinfection - Discharge Pump and Pump Vault Pumped Discharge Line Discharge Point with Rip-Rap Flow Path to"Blue Line"Water Feature The proposed discharge point is in an existing pond located on the adjacent property to the north that discharges north into an existing tributary of Indian Creek. A drainage easement will be required for the adjacent property to the north of the subject property as is included in Attachment G. The drainage easement and a map showing the path from the proposed discharge point to the first "blue-line" feature, as shown on the Chatham County GIS data, can be seen in Attachment G. Notice of Intent As part of the Notice of Intent, the feasibility of alternatives to discharging must be addressed. The following alternatives are to be evaluated: Connection to a regional or municipal sewer collection system Letter from the local or county health department describing the suitability or non-suitability of the site for all types of wastewater ground adsorption and innovative non-discharge systems, as well as documenting the repair potential of the failed system. Investigate land application such as spray irrigation or drip irrigation. Connection to a Regional or Municipal Sewer Collection System Connection to a sewer collection system is not feasible for this facility. Mr. Andrew Perkinson, City of Henderson Public Works Director, was contacted to determine if the property is within the City's coverage area. As of the date of this submission, a response has not been received in regard to the location of sewer in the vicinity of the property. The closest current sewer is assumed to be at least 4,000 linear ft. from the property, and it is assumed that there are no immediate plans for a sewer extension to the area at this time (Attachment H). For reference, if an installation cost of $100/ft of installed sewer line was assumed, the cost to connect this property to the sewer line would be approximately$400,000. Additional costs including the cost of the pump station,potential "tap"or sewer capital fees, road repair costs, frontage fees and fees for right of way permits would also be incurred by the owner. Letter from the local or county health department describing the suitability or non- suitability of the site for all types of wastewater ground adsorption and innovative non- discharge systems. Document the repair potential of the failed system. Mr. Chris Hedrick of the Granville-Vance District Health Department indicated that the site is unsuitable for installation of a ground absorption septic system in a letter dated February 4,2022. The denial indicated that a repair permit cannot be issued due to unsuitable soil characteristics, unsuitable soil wetness conditions,unsuitable soil depth, and insufficient space (Attachment B). Investigate Land Application such as spray irrigation or drip irrigation. Per the soil evaluation by Chris McGee of Agri-Waste Technology, Inc. the site does not have suitable soil characteristics to accommodate a non-discharge surface spray or drip wastewater system. 7Q10 Flow Estimate The United States Geological Survey (USGS) was contacted to determine the 7Q10 flow estimate for the downstream tributary of the proposed wastewater discharge point. The proposed discharge point is in an existing pond located on the adjacent property to the north that discharges north into an existing tributary of Indian Creek. The analysis from USGS indicates the 7Q10 discharge for the point in question is likely zero (Attachment F). Engineering Alternatives Analysis An Engineering Alternatives Analysis (EAA) has been completed for this site and is included as Attachment I. In my opinion, the completed EAA demonstrates that a wastewater treatment system permitted under the NCG550000 General Discharge Permit is the only feasible option for this site. We have exhausted all other options for this site as follows: a.) connection to a municipal or regional sewer collection system - Not feasible due to costs. b.) subsurface disposal - No suitable soil for a subsurface absorption system. - Not feasible due to costs. c.) wastewater irrigation (drip and spray) - Unsuitable soil and insufficient space for a non-discharge ground absorption system. - Not feasible due to costs. d.) reclaimed-water systems - No suitable soil for a reclaimed water system. No reasonable ability to operate as a bulk distributor of reclaimed water. e.) Any viable combination of the above - There are no viable combinations of the above due to soil and cost limitations. I i r Local Government Review Forms As part of the EAA,Local Government Review Forms were sent to Vance County and the City of Henderson. To date,the completed forms have not been received. A copy of the submittal is included as Attachment J. I appreciate your time and efforts in reviewing this application. If you have any questions or comments,please feel free to contact me at 919-859-0669. Best Regards, IL°44 — Scott P. Jones, P.E.
