The main supply and return lines shall be installed below the host line Mand shall feed the shallow 'top feed' manifolds with a single vertical section of insulated sell 40 PVC pipe. Insulation shall be minimum 1/2' thick foam insulation (o muivdmt). On But sites where 'top feed' manifolds will not drain therefore requiring the use of side feed me hifuds, 12' .- is recommended bell - highest point of 1/2' black fexble PVC pipe (non loop connections) and final grade. On trip tubing installations less than 12' this would require additional cover over the header ditch arm to create the 12' separation. Any additional cover is it to be graded and tooled into landscape. Please see note an loop cannections below. Dense vegetation turf cover to be established over supply branch, return trench and tubing prior to 1st exposure to cold weather. It vegetation cannot be established, than trenches and tubing to be covered with a thick lover, (minimum 6') of mulch, straw/hay, etc until soon turf cover is established. Cover must be stabilized and maintained until dmw vegetative turf is established Amount of cover may need to be adjusted to account far settling.

If fiberglass insulation is used It must be sealed to prevent it from becoming saturated. The 'remote Mires' shall be Placed on a bed of gravel m screenings (4'-6'). Positive grade away tram Mve boxes is encouraged to reduce the volume of groundwater that may collect in wave box. Certain sites may require positive drains to daylight Ali loops connecting alp runs with 1/2' flexible PVC shall be slightly elevated (minimum 1'-2') so that they drain into the trip tubing after the Pump shuts off.

Project Summary for: Boikova Residence — 3 bedrooms Union County, NC. The project is located at 461 Union Road to the east of Mint Hill, NC in Union County. The proposed house is a 3-bedroom house and is to be designed at 120 gpd for 360 gpd. There is an adjacent business to the property. This is shown on the plan and is over 200 feet away so that it doesn't affect this site with any setback requirements. The tract of land is wooded, light in underbrush and easy to traverse. The disposal area has not been disturbed and will need to be cleared. A Surface Drip Wastewater Disposal system is proposed because of the lack of adequate available subsurface soils. It has an underlayment of heavy clay along with seasonal high water. The site drains from the back of the property down toward the road and a culvert to an upland tributary (dry weather) with a very small watershed (from just above the site). The stormwater from the watershed directly uphill from the site is diverted away from the disposal area by a proposed ditch that is to be installed with the wastewater improvements. The Watershed Classification for this area is "C", within the Yadkin watershed and drains specifically to the Pee Dee River and is in the upper watershed of Duck Creek. The Health Department was consulted, and they determined that the site was unsuitable for a subsurface system. The owner hired an independent Soil Scientist to make a detailed analysis of the soils on the site. Thompson Environmental determined that expansive clays were near the existing surface along with a seasonal high-water table and concurred with the findings of the Health Department. Thompson Environmental performed additional sampling, boring, ksat work for the disposal area, performed a stream analysis, water balance, and coordinated for an Agronomist Evaluation. This report and supporting documents Page 5 are included in this submittal along with a copy of the Health Department "Denial" for subsurface. The system will consist of a new Norweco Singular Green Bio-Kinetic Unit with a BioFilm Reactor Unit. An Ultraviolet disinfection unit outside the Pump Tank is used to sterilize the effluent as it is pumped to the disposal site. A simplex Puturb effluent pump system inside the Pump Tank is recommended for this discharge. The system utilizes a Norweco Control Panel for the PreTreat units and UV Light and an American Control Panel for the Pump Tank and Headworks Unit. Each panel is housed within a NEMA 4X enclosure that is setup for the floats, pumps and internal monitoring of the system. A programmable micro -logic controller (PLC) activates the discharge pump through a program that self -adjusts these operations based on actual wastewater flow into the processor (as monitored by the PLC). The processor constantly evaluates the water usage and meters out the effluent discharge to the disposal area at the appropriate interval to assure proper effluent treatment. The proposed PreTreat Tanks are made of HDPE and the Pump Tank is made of precast concrete. Floatation of the tanks is not a factor as the units are being installed above the road and not subjected to flooding. However, calculations for floatation are included in this submittal.

If there are any questions regarding these guidelines, design and installation personnel should contact Thompson Environmental Consulting, Inc. (TEC) for clarification. These guidelines are presented as TEC's professional opinion and are not dictated by the NC DWR. However, the NC DWR retains the right to determine what constitutes suitable fill material and installation thereof, as the regulatory authority responsible for permitting this waste water disposal system. Surface water diversion: Surface water will need to be diverted away from the proposed application area. Fill material composition: The fill material should consist of mineral soil with a textural classification of sandy loam. It shall consist of no more than 10 percent of rock fragments (> 2 min in size), organic material, etc. Once a source of fill material is found, a sample should be submitted to TEC personnel so that a particle size analysis can be conducted. Note: Before any earth moving activities are conducted on site, TEC should be contacted to mark the fill area boundary and inspect the moisture content of the soil. If the soils are too saturated, no tillage may occur. This inspection is to avoid compacting the application area. All site work should be conducted by machinery with tracks instead of pneumatic tires. 1. The existing ground surface should be lightly tilled/scarified lightly and should extend at least three (5) feet beyond the intended irrigation area on all sides. 2. Three (3) inches of approved fill material should be applied to the disposal area and tilled into the application area and then lightly rolled with a lawn roller filled approximately one quarter (1/4) of water (or equivalent technique). The soil should not be overly compacted during this process. 3. At this point, the total depth of fill should be at least three (3) inches above the initial ground surface. If three (3) inches has not been achieved, continue applying fill as outlined in step 3 until a minimum of three (3) inches is present. 4. The fill material should extend five (5) feet beyond the proposed disposal area. From this point, the fill should be tapered down to the surrounding ground surface with a berm slope not to exceed a 1:4 rise to run ratio. In other words, there should not be any more than one (1) inch of rise for every four (4) inches of run, making the berm one (1) foot wide at a minimum for the proposed three (3) inches of proposed fill. Page 59 Turf option: The entire area should be temporarily seeded with an appropriate turf species for the area, covered with hay or other suitable temporary cover that will both protect the seed and soil from erosion while the pine/hardwood duff layer is regenerated. Temporary irrigation should be provided to the area so that a suitable stand of turf takes root. Care should be taken not to erode the installed fill. Mulch option: If a mulch cover is chosen, TEC personnel should be contacted for a visual inspection of the fill material once it has been put into place, but before mulch is applied. Once formal approval has been granted that the site meets the design criteria, an approved mulch can be applied on top of the fill. The mulch should not exceed a depth of two (2) inches. The site must be maintained with a continuous cover of mulch at all times until the pine/hardwood duff layer is regenerated. The drip tubing is the installed over the mulch. TEC should be contacted to conduct another visual inspection of the drip tubing after installation. If it is determined that the mulch is not acting as an adequate erosion protection technique, it should be replaced with a stand of turf.

The design daily flow is 360 gallons per day (GPD). The proposed system will operate in accordance with state rules 15A NCAC 02T. 0600 (2T Rules). 1.3 Proposed Wastewater System Wastewater will be treated to the minimum monthly average standards. Wastewater will be applied using surface drip irrigation. 1.4 Study Area A preliminary soil evaluation was completed in select areas of the project site. The Study Area referred to in this report consists of the 1.0± acres on the western portion of the property outside of property line setbacks and powerline corridors (Figure 2). 2.0 OBJECTIVES The objectives of this investigation were to evaluate pertinent site conditions and identify a satisfactory wastewater application area within the Study Area and to provide recommendations to its utilization. Specific attributes evaluated included the soils, vegetation, topography, hydraulic assimilative capacity, jurisdictional features, and landscape position. 3.0 INVESTIGATION METHODOLOGY A Soil and Site Evaluation was conducted by TEC in June and July 2018, by Larry B. Thompson, LSS and Evan T. Morgan, LSS-IT. 3.1 Soil Evaluation Soil borings were made with a hand -turned auger and soil color was determined with a Munsell Soil Color Chart. Soil profiles were described per the Field Book for Describing and Sampling Soils, version 3.0. Landscape characteristics were noted (slope, drainage 461 Union Road SFR Soil Scientist Evaluation 1 July 2018 Page 29 patterns, etc.) as well as soil properties (depth, texture, structure, soil wetness, restrictive horizons, etc.) to auger refusal. Soil borings were described under moist conditions. Additional borings were advanced to shallower depths to identify diagnostic horizons and record soil properties. A hand-held GPS unit with sub -meter accuracy was used to locate each soil boring as well as other site features. 3.2 Saturated Hydraulic Conductivity Testing and Reporting Saturated hydraulic conductivity (KSAT) measurements were performed with a compact constant -head permeameter (Amoozemeter). An Amoozemeter was used because of the need to conduct the test below current grade. KSAT test values were generated using the published calculations and formulas found in the corresponding User's Manual (Amoozegar). The Glover solution was chosen as the most appropriate method for calculating KSAT values. The Glover solution is recommended when the distance between the bottom of the auger hole and any impermeable layer(s) is greater than 2 times the head (H), or constant water level in the hole. The Glover solution is given by: KSAT = AQ Where: A= {sinh"'(H/r)-[(r/H)2+1] 1/2+r/H} / (27EH2) And: Q is the steady-state rate of water flow from the Amoozemeter into the auger hole. To solve for A: H is the head in the hole (i.e. total water depth) and r is the radius of the hole. Values for H and r can be found on the attached KSAT data sheets. 4.0 STUDY AREA DESCRIPTION 4.1 Regional Geology and Local Topography The project site is located in the Piedmont physiographic region. The general lithology consists of fine textured late Proterozoic -Cambrian rocks. The general topography includes gently rolling hills and ridges with fairly broad drainages (Figure 1). Typical slopes ranged from 2% to 6%. 4.2 Vegetation The vegetation in the Study Area consisted of pine, hardwood, and soft wood species including: Virginia pine (Pinus virginiana) loblolly pine (Pinus taeda), red maple (Acer rubrum), sweet gum (Liquidambar styraciva), post oak (Quercus stellate), southern red oak (Quercus falcata) and red cedar (Juniperus virginiana). Dominant species were pine, oak, and sweetgum. The diameter at breast height (DBH) ranged from 8 to 12 inches for the majority of canopy species. 461 Union Road SFR Soil Scientist Evaluation 2 July 2018 Page 30 4.3 Jurisdictional Features No jurisdictional streams or wetlands were identified on the parcel. 4.4 Soils Soils in the Study Area are located in the Carolina Slate Belt and formed in residuum weathered from argillite or other fine-grained metavolcanic rocks (phyllite and schist). The Web Soil Survey was referenced prior to the field investigation to get an overview of the possible soil series mapped in the Study Area. The Tarrus soil series is mapped in the Study Area (Figure 3). Information for this series is listed in Table 1. Six (6) soil borings were advanced to characterize the dominating soil properties and their locations are noted on Figure 2. The Cid soil series was identified within the Study Area by a brownish yellow, colored Bt horizon overlying a similarly colored BC horizon that showed signs of iron depletions within 17 inches and significant parent material (Figure 4). Cr horizons exhibited weathered rock with seams of gray depletions. Evidence of a perched water table (PWT) was observed throughout the soils in the study area, ranging in depth from 10-17 inches. A seasonal high water table (SHWT) was not observed before auger refusal. 4.5 Fill Material As stated above, a perched SHWT was recorded ranging from 10 to 17 inches. State regulations require 12-inches separation from the point of wastewater application (soil surface) to a PWT. Due to the variability in depth to the PWT throughout the application area, three inches of appropriate fill material is proposed to be added final application area. A Fill Application Plan is appended and outlines the appropriate activities needed to apply the fill material. 4.6 Saturated Hydraulic Conductivity Testing Surface application systems require KsAT tests be performed to substantiate the recommended hydraulic loading rate. KsAT tests are conducted in the most hydraulically limiting soil horizon within seven feet of the naturally occurring surface. In all, 6 KsAT measurements were conducted and their locations shown on Figure 2. Measurements were conducted in lower BC horizons as it was determined as the most hydraulically limiting soil horizon. The results of KsAT measurements are listed in Table 2. 461 Union Road SFR Soil Scientist Evaluation July 2018 Page 31 Table 2. KSAT Test Results. 1 B 1 37 BC 0.0048 2 B2 17 BC 0.0555 3 B3 22 BC 0.0084 4 B4 23 BC 0.0040 5 B5 22 BC 1 0.0079 6 B6 24 BC 0.0111 KsAT test results provided consistent measurements. The measured KsAT rate for the BC horizon is 0.0096 in/hr. KsAT data sheets are appended. 4.7 Soil Fertility Analysis Soil samples were collected in the upper 12 inches and analyzed by Waypoint Analytical, Inc. The results are typical for a mature forest piedmont soil. Soil phosphorus (P) is rated low. The wastewater applied will help raise the soil P levels to a normal range. Full soil fertility results are appended. 5.0 HYDRAULIC LOADING RATE ASSESSMENT The hydraulic loading rate is the amount of wastewater that can be applied to the Application Area and is derived from in -situ KsAT data, vegetation, nutrient loading, and best professional judgement. 5.1 Design Coefficient and Justification The geometric mean for KsAT measurements conducted in the BC horizons was calculated as 0.0096 in/hr (1.61 in/wk). This KsAT rate must be modified by a Drainage Coefficient to determine the hydraulic loading rate. A design factor of 0.50 is proposed for the Application Area resulting in a soil drainage rate of 0.115548 inches/day. Sites can utilize higher drainage factors with favorable parameters such as: • Receiver crop type and Application Area conditions • Physical characteristics that promote infiltration into surface horizons and percolation through to subsurface horizons • Favorable landscapes for wastewater application The Study Area, and subsequent Application Area, is forested and is advantageous to wastewater assimilation. Forest systems and soils are typically nutrient limited and can readily take-up wastewater and wastewater constituents during most of the year. The thick canopy lessens surficial impacts from raindrops during rainfall events thus reducing runoff potential. The underlying duff layer consists of organic material and supports ideal habitat for soil microbes that can readily ingest added nutrients as well as soil 461 Union Road SFR Soil Scientist Evaluation July 2018 Page 32 macro -organisms that will aid in soil aggregation and stability. The latter will also aid in wastewater infiltration. The soil borings described in the Study Area exhibited friable silt loam surfaces that ranged from 6 to 15 inches with friable silty clay loam to clay Bt horizons typically extending from 10 to 28 inches from the surface. The silt loam surfaces will facilitate infiltration of applied wastewater while the Bt horizon will provide storage to allow wastewater to further permeate vertically or move laterally along the landscape. The landscape positions that occur within the Study Area consist of broad, flat ridge and linear slopes. The average slope for the Application Area is 4%. This slope will allow for infiltrated wastewater to move laterally away from the Application Area. Wastewater for surface application systems is treated more than regular domestic wastewater. Higher drainage factors can be utilized for wastewater treated to these standards. Lowered concentrations of wastewater constituents such as biological oxygen demand (BOD), total suspended solids (TSS), ammonia, fecal coliforms, as well as nutrients N and P attained by secondary treatment reduce detrimental impacts from application of wastewater. 5.2 Water Balance Calculation & Recommended Loading Rates A monthly water balance was calculated to determine the maximum annual loading rate using NCDEQ Division of Water Resources, Single -Family Residence Loading Rate Worksheet based on a design daily flow of 480 GPD. Monthly precipitation data came from the State Climate Office of North Carolina CRONOS Database located in Salisbury (Station: SALI), from a period of 1985 to 2018 (33 yrs). Evapotranspiration was calculated using the conservative Thornthwaite method, which utilizes temperature values from the same source and period as the precipitation data. The geometric mean for KsnT tests conducted in the BC horizons (0.0096 in/hr) was used for the percolation rate. Using a 0.50 Drainage Coefficient the maximum allowable irrigation rate calculated by the water balance is 18.12 in/yr for an irrigation area of 0.267 acres (11,631 sq-ft). The 18.12 in/yr annual hydraulic loading rate is on the higher end for an SFR-C group soil; but is supported with a Ksa,T rate that is on the higher end for SFR-C and a relatively moderate drainage coefficient. Based upon the results of the site investigation and our professional experience, we recommend the following loading rate: • Weekly Loading Rate of 0.4 in/wk 5.3 Instantaneous Loading Rate The instantaneous loading rate is the amount of wastewater that should be applied in a single event. There is published data that recommends instantaneous (or infiltration) rates for particular soil types (textures) and landscape positions (Sprinkler Irrigation, 461 Union Road SFR Soil Scientist Evaluation July 2018 Page 33 1969). These rates must then be adjusted based on site -specific conditions. The factors considered at the project site included: • The surface horizon is typically a silt loam that generally extends at least 6 to 15 inches in depth. • Abundant soil organic matter exists in the duff layer that will aid infiltration. • The topography is generally a 4% slope that will allow for infiltration. Based on these considerations, a maximum instantaneous loading rate of 0.15 in/hr is recommended for the Application Area. 5A Minimum Required Storage Storage is proposed to be contained on -site in tanks. The minimum storage for a single- family residence is 5-days or 1,800 gallons. 6.0 AGRONOMIC REPORT The Agronomist Evaluation of the Study Area was completed to include recommendations for the receiving crop, its ability to accept proposed loading rates (both hydraulic and nutrient) and provide information to ensure proper maintenance of the recommended receiving crop. 6.1 Receiving Crop The receiving crop will consist of a mature forest stand. Dominant species are listed in Section 4.2 of this report. Wastewater application to forested areas is beneficial in many aspects. Forests provide a steady source of organic matter and are typically nutrient deprived. Mature trees can take-up a vast amount of water with some large trees absorbing as much as 100 GPD. Rooting habits of mature trees also include deep penetration and perennial growth. 6.2 Wastewater Characterization Typical wastewater contains varying levels of essential plant nutrients, organic compounds, trace minerals, and potentially phytotoxic compounds. Each of these typical wastewater constituents are assimilated or transformed on a wastewater receiver site through physical, chemical, and biological processes. The effluent will be treated to minimum monthly average water standards listed in 15A NCAC 02T .0605(b). Treatment will be to monthly average levels that shall not exceed 30mg/L BODs, 30mg/L TSS, 15mg/L Ammonia, and 200 colonies/100 ml Fecal Coliform. 6.3 Nutrient Loadings As limited as this site is hydraulically, the site will not be limited by nutrient levels. 461 Union Road SFR Soil Scientist Evaluation July 2018 Page 34 6A Soil Testing and Recommendations Periodic fertility sampling and monitoring of micronutrients, such as sodium (Na), calcium (Ca), and magnesium (Mg), is recommended to ensure optimal receiver crop efficacy. Application of gypsum may be required as a corrective measure if the sodium adsorption ratio (SAR) is consistently above 10. Irrigation wastewater should have SAR values < 10 to avoid potential adverse growing conditions related to soluble salts in the soil. 6.5 Vegetation Maintenance/Monitoring & Recommendations Advantages associated with matures trees as wastewater receiver crops regarding hydraulic and nutrient loading capacities have been previously stated. Additional advantages include little to no vehicular traffic, no need for cutting and removing of residues, and regular maintenance accustomed to producing annual crops. Thinning of saplings and shrubs is recommended. Thinning and pruning of diseased trees should be completed immediately upon identification. 7.0 CONCLUSIONS TEC is proposing the installation of a 360 GPD single-family residence surface application system. TEC completed soil borings, KsAT tests, and soil fertility data to verify favorable soil properties exist for wastewater application. An annual hydraulic loading rate of 18.12 in/yr was calculated with the NCDEQ Division of Water Resources, SFR Loading Rate Worksheet and site -specific soil data. A minimum Application Area of 0.267 ac (11,631 sq-ft) will be required. Weekly loading rates should not exceed 0.4 in/wk with an instantaneous loading rate of 0.15 in/yr per event. The Application Area is most limited hydraulically. Applying at the design irrigation rate will not lead to excess nutrients to the Application Area. The Application Area should be evaluated annually. A wastewater sampling program should be instituted to ensure optimum nutrient inputs to the cover crop being irrigated by this proposed system. The wastewater parameters to be monitored include the following, as a minimum: total nitrogen, total phosphorus, potassium, sodium, calcium, magnesium, copper, and zinc. Fill material will have to be placed over the entire Application Area prior to installation of the drip tubing. The Fill Application Plan in Appendix F should be followed, and TEC should be consulted on the material chosen. 461 Union Road SFR Soil Scientist Evaluation 7 July 2018 Page 35 8.0 REFERENCES Auchmoody, L.
