Attached, please find responses to each of the questions/comments listed in your letter dated January 24, 2024. To facilitate the review of this response, I have included each point from the comment letter below. A. Soil Evaluation: Chris Smith of the Raleigh Regional Office noted the following: a. The evaluation narrative states "The area evaluated and suitable for the proposed system is about 46,000 ft2, so ample space is available for the wastewater irrigation system anywhere within the evaluated area." The disposal area calculation is using a Drainage Coefficient (DC) of 13%. According to the DWR Soil Scientist Evaluation Policy and the EPA Process Design Manual: Land Treatment of Municipal Wastewater Effluents (EPA 625/R-06/016) a DC of 4- 10% is recommended. The inconsistency of the Ksat values (0.01, 0.02, and 0.09 in/hr) and the stated shallow depth to the high water table do not support an elevated DC. DWR staff recommends that the DC be reduced to a maximum of 10% and the disposal area size be increased. i. Response detailed in stamped Soils letter. b. The report states the water table on the site is perched. Low chroma colors are described at depths of 5", 6", and I F for Ksat measurement locations 1, 2, and 3 respectively. The low chroma values continue to be described throughout the soil profile after the initial observance depth at every Ksat nest location. The continued observance of these low chroma values throughout the evaluation range potentially indicates an extended period of saturation through the lower parts of the soil profile and does not support the statement that the water table encountered is perched. c. The application does not include a clear and detailed soils map. A site drawing is included, but lines delineating various features are not continuous due to the inclusion of text labels. An aerial image map clearly delineating soil series polygons, Ksat nest locations, and soil boring locations should be provided to assist DWR staff in locating these features in the field. d. The site drawing provided appears to show both Creedmoor and White Store soil series with differing slopes present in the proposed disposal area, but only Creedmoor is mentioned in the evaluation. Ksat data and soil profile descriptions are provided only for the Creedmoor series. No explanation has been offered for the exclusion of the White Store series from the soils evaluation. Please explain. Please respond to the above concerns and give further insight into the decision making process for this site. Additionally, the plot included for Ksat 1 shows a linear increase across the final three measured values. This does not indicate that steady state within this test was achieved. Please explain how steady state was determined within this specific test. B. Engineering Calculations: 1. According to the engineering calculations, 0.48 acres of irrigation area has been designed for the system. Form: SFRWWIS 06-16 notes that the irrigation area is 0.53 acres (including blanking). Of the 0.53 total acres, how much area is being wetted and contributing to the irrigation capacity of the facility? a. Due to soils accommodations, the design has been updated, and affected components have been included with this response. Thank you for your assistance with this application.

CY d 7354 NORYN Response to Additional Information Request Concerning Escobar Single -Family Residence Wastewater Irrigation System PREPARED FOR: Cord Anthony, Division of Water Resources PREPARED BY: Jeff Vaughan, Ph.D., L.S.S. Senior Agronomist/Soil Scientist Heath Clapp, L.S.S. Senior Soil Scientist DATE: February 21, 2024 This letter, sealed with the L. S. S. stamps of Jeff Vaughan and Heath Clapp, is in response to an additional information request received from Cord Anthony in regard to permit application #WQ0044892 for a Single -Family Residence Wastewater Irrigation System. Item I Response: A drainage coefficient of 10% has been achieved by increasing the disposal area size to approximately 28,399 square feet. Item 113 Response: Per the USDA -MRCS Official Series Description Sheets of both soil types mapped within the proposed drain field area (Creedmoor sandy loam and White Store sandy loam), the `Tabular Series Date' section at the bottom of the description states that the water table kind is perched. Also accounted for in the Official Series Description Sheets for both soil types is the presence of low chroma (< 2) values from initial observation until the official description depth is reached (60-69"). This is consistent with the described deep boring performed by AWT, to the required depth of 84". Concrete evidence of a water table being perched as opposed to apparent can't always be established if the perched water table goes below the required depth of the deep boring. The USDA-NRCS Official Series Description Sheets for both soil types will be included in attachment 1. Item I Response: An aerial map utilizing the data contained in the drawing has been created and is included in attachment 2. Item 1D Response: All borings performed in the disposal field portion of the property were more indicative of a Creedmoor sandy loam than a White Store sandy loam. No slickensides as well as the presence of gleyed horizons more closely resembles the Creedmoor sandy loam soil series. Additional Response Regarding Ksat 1: AWT follows all Johnson Permeameter manufacturer practices as well as industry standards (running Ksats a minimum of 3-4 hours in heavy clays). Equilibrium for Ksat 1 was calculated based on the sawtooth pattern that the data presented, showing a slowly increasing trend. The last 3 values recorded (one being the lowest value recorded and one being the highest value recorded) were averaged to reach the value that was used. This Ksat ran longer would have likely ended up running at a higher rate based on the trend of the data. AWT's assumption of what happened in this scenario is that that water took time to fill the micro/macropores of the slightly smeared expansive clay (from the auger boring) where it bottomed out, and eventually started having preferential flow, showing the increasing trend. AWT believes that the value used was reasonably conservative. 2 Attachment 1: USDA-NRCS Official Series Description Sheets LOCATION CREEDMOOR NC+SC VA Established Series Rev.

Contractor to document system installation with photographs. 5. Contractor shall backfill around all access areas such that storm water is shed away from potential entry points. OPERATION AND MAINTENANCE SCHEDULE: 1. A contractor or other qualified professional should be contacted if you are uncomfortable or unfamiliar with operating this system or if system troubleshooting is necessary. 2. The Septic Tank Effluent Filter shall be cleaned at least every 6 months or per manufacturer's recommendations. Check Septic Tank solids level annually. In general, it is recommended that solids be pumped from the Septic Tank every 3-5 years. 3. A clean -out is located on the system just before the Septic Tank. If liquid backs up into the house or the Septic Tank, the drainline may be clogged or the Septic Tank may have too many solids in it to allow adequate flow through. A qualified contractor should be contacted to unclog any blockages via these clean -outs. A pumping contractor should be used to empty solids from the Septic Tank. 4. Effluent from the AdvanTex treatment system shall be sampled per the requirements of the system permit. If no parameters are listed, AWT recommends sampling for the following parameters; Total Suspended Solids (TSS), Biological Oxygen Demand (BOD5), Total Nitrogen (TN), Ammonia -Nitrogen (NH3-N), and Fecal Coliform. 5. Maintenance of the AdvanTex treatment system should be conducted by a certified operator under contract with the homeowner. 6. Invert elevations of all components to be verified in field by contractor to insure proper operation. 6. The UV component shall be checked Weekly to ensure the alarm bulb (on control panel) is not illuminated. The UV bulb should be cleaned on a 6 month interval.

Upon system completion, Contractor to supply Engineer with documentation of installation and a signed letter indicating system was installed per approved design or noting any deviation from approved design. 7. The storage and pumping component shall be checked Weekly to ensure the alarm bulb (on control panel) is not illuminated. If the control panel indicates the system is in alarm mode, the following steps should be taken: • Stop use of all Water in the residence (to stop flow into the pump tank), • Verify that the system has electrical power. • Contact a qualified contractor to inspect the system (if needed). If it has rained recently the pump may not be operating because the rain sensor is temporarily blocking the system from 10. All system piping to be SCH40 PVC. operating. If this is the case then the pump will resume operation once it is dry enough. If the pump tank is in danger of overflowing and continued rainfall is expected, contact a septic tank pump contractor to remove a portion of the liquid in the 11.

All risers to have cast -in tank adapters and be single -piece risers Risers shall be secured to cast -in tank adapters per manufacturer's recommendations. Risers to extend 6" above soil surface and be designed and maintained to prevent surface Water inflow. Risers to be gasketed and secured with four (4) 5/16" diameter screws. 8. It is important to inspect the pump tank, and components on an annual basis to ensure no solids are building up on the tank bottom, to ensure that the pump control switches are placed properly, and to verify proper pumping of the effluent. These activities will be handled by the engaged service provider. 9. The location of the supply line should be Walked Weekly to ensure that a line breakage has not occurred. The area in which the line is buried should be monitored for any wet spots or locations of excessive vegetation growth as these occurrences may be an indication of a line breakage. No permanent structure shall be erected over the locations of the Supply and Return lines. No heavy vehicles or equipment should be driven over the Supply and Return lines. 10. The dripfield should be inspected Weekly to verify proper operation and to ensure driplines have not become damaged. Clogged or worn drip tubing should be replaced or, in the event of minimal obstruction, cleaned. No heavy vehicles or equipment should be driven over the irrigation area.
