CONCLUSIONS AND RECOMMENDATIONS �+ APPENDICES ow m" o" am ow am f, am em f—" em so am no SECTION I INTRODUCTION The Riverstone Industrial Park is an industrial complex that is proposed to be developed in the southern portion of Rutherford County, North Carolina, adjacent to the Broad River and U.S. Highway 221. The industrial park is currently designed to contain approximately 48 separate lots, totaling approximately 1,152 acres. Ultimately, the industrial park is expected to employ 5,000 workers. The developer of the property, Stonecutter Mills Corporation, has agreed ow to give the nearby Town of Forest City approximately 17 acres of land on the industrial park property for the construction of a wastewater treatment facility to serve the park. The Riverstone Wastewater Treatment Plant is planned to be owned and operated by the Town of Forest City, and is proposed to be located near the confluence of Floyd's Creek and the Broad River to allow a wastewater discharge to the Broad River. ow If constructed, the Riverstone Wastewater Treatment Facility could also be used to treat the wastewater generated at Chase High School (located approximately 3.4 miles north of the industrial park), in addition to numerous homes in the surrounding area of the school and the industrial park. Wastewater flow from the high school is currently pumped through five (5) separate lift stations prior to treatment at the Town of Forest City Wastewater Treatment Plant. am MR 1 am This study evaluates alternatives for the treatment and disposal of wastewater from the proposed industrial facility. The alternatives have been evaluated on an estimated construction cost basis as well as a present worth basis over a twenty-year operations period. The alternatives that have been evaluated are: • Alternative No.1 - No Action • Alternative No. 2 - Connection to Publicly Owned Treatment works Alternative 2-A — Connection to Town of Forest City Sewer Svstem Alternative 2-B — Connection to Cliffside Sanitary Sewer District WWTP Alternative 2-C — Connection to Chesnee, South Carolina Sewer System • Alternative No. 3 - Connection to a Privately Owned Treatment Works • Alternative No. 4 — Individual and Community Subsurface Systems ,^ • Alternative No. 6 — Surface water Discharge Through NPDES Permit ., System • Alternative No. 6 — Drip Irrigation • Alternative No. 7 — Spray Irrigation "'' • Alternative No. 8 — Reuse am am M FM IM 2 5ECTION II DESCRIPTION OF NEEDS As previously mentioned, the Riverstone Industrial Park is proposed to be developed in the southern portion of Rutherford County, adjacent to the Broad River and Highway 221. Wastewater generated by this facility is proposed to be treated at the Riverstone Wastewater Treatment Plant (WWTP), which is planned to be constructed near the confluence of Floyd's Creek and the Broad River. A location map of the proposed industrial park site and wastewater treatment plant site is included in Figure 2-1. Ultimately, it is anticipated that the industrial park will employ approximately 5,000 people. In addition, the Riverstone WWTP may also be used to treat wastewater generated at Chase High School (see Figure 2-1), and approximately 200 homes in the vicinity of the high school and the industrial park that are not currently served by the Town's sewer system. Therefore, wastewater flow to the WWTP in gallons per day (GPD) is ultimately anticipated 5713511159 M. 5,000 employees X 25 GPD/employee = 125,000 GPD Chase High School flow (per water billing records) = 15, 000 GPD 200 homes X 3 bedrooms/home X 120 GPD/bedroom = 72, 000 GPD t�-� Industrial Process Flow (Estimated) = 238, 000 GPD�- TOTAL ESTIMATED FLOW = 450,000 It is therefore proposed to obtain an NPDES permit and construct a wastewater treatment plant with a capacity of 450,000 GPD to serve the above 3 described areas. Due to the fact that it may take several years for the industrial park to reach its full capacity, it is proposed to construct the project in two (2) phases. Phase 1 of the project would consist of the construction of a 100,000 GPD wastewater treatment facility to serve the initial facilities that locate to the industrial park, and could allow for immediate plans to construct sewer lines to r serve Chase High School and the surrounding area. Phase 2 of the project is proposed to take place approximately ten (10) years after the construction of the Phase 1 facility. Phase 2 would consist of the upgrade of the facility from 100,000 GPD to 450,000 GPD to allow for the increase in flow that is eventually expected to be treated at the Riverstone Wastewater Treatment Plant.

Included in this discussion 0" are estimates of the capital costs of each alternative as well as a present worth analysis for the 20 year planning period. The costs will be used to compare the various alternatives, and to make recommendations for wastewater disposal at the facility. ALTERNATIVE NO. 1 — NO ACTION This alternative consists of no action being taken by the Town of Forest City to provide wastewater treatment to the Riverstone Industrial Park. Without an adequate method of wastewater disposal, the land could not be developed into the industrial park, resulting in a loss of the 5,000 jobs that are anticipated to be available by the construction of the park. The development of the industrial park is expected to provide significant economic growth to both the Town of Forest City and Rutherford County. To allow for this growth, it appears to be in the best interest of the Town to provide a method of wastewater disposal to the industrial park site. Alternative No. 1 is therefore not an acceptable alternative and will not MM be discussed in further detail. R" a+ 5 ALTERNATIVE NO. 2 — CONNECTION TO A PUBLICLY OWNED TREATMENT WORKS Three (3) public sanitary sewer systems are currently known to be located within five (5) miles of the proposed industrial park site. The systems are as follows: A. The Town of Forest City operates a wastewater pump station that is located at Chase High School, approximately 3.4 miles north of the — industrial park site (Alternative 2-A). B. Cone Mills Corporation operates a WWTP that includes domestic flow from the Cliffside Sanitary Sewer District, and is located approximately five (5) miles to the northeast of the proposed industrial park site (Alternative 2-13). C. The Town limits of Chesnee, South Carolina are located approximately four (4) miles to the south of the proposed industrial park site. The Town operates a wastewater treatment facility with a design capacity of 0.5 MGD (Alternative 2-C). Alternative 2-A — Connection to Town of Forest City Sewer System Alternative No. 2-A involves connecting to the Town of Forest City's wastewater collection system by pumping the flow from the Riverstone Industrial Park to the existing Chase High School lift station. This alternative would require a lift station to be constructed at the same location as the proposed wastewater R treatment plant to collect all flow generated at the industrial park. Due to the elevation differences between the proposed lift station location and the existing lift station at the high school (approximately 200 feet), at least two (2) new wastewater lift stations would need to be constructed to pump the flow from the industrial park to the school. Based on preliminary calculations that are included in Appendix C, it is assumed that two (2) submersible pump stations, each consisting of a concrete wet well with two (2) submersible solids handling pumps, control panel, emergency generator, and a chain link fence would be required to pump the flow from the industrial park to the existing high school lift station. Figure 3-1 includes a preliminary map of the proposed lift station locations, and the location of Chase High School pump station. If this alternative were selected, wastewater flow from Chase High School would continue to be pumped to the Town's sewage system by the existing high school lift station. Therefore, the 15,000 GPD of flow from the high school that is included in the estimated Riverstone WWTP flows would not be included in the flows received by the industrial park lift stations. Flow from the 200 homes in the vicinity of the industrial park and high school is assumed to be included in the potential flow to the industrial park lift station. For hydraulic purposes (See Appendix C), Phase 1 of the project would consist of the construction of two (2) lift stations and related force mains to adequately pump an average daily flow of 100,000 GPD to the existing Chase High School lift station. Wastewater flow that currently enters the high school lift 7 station is pumped through five (5) separate lift stations prior to final treatment at the Town of Forest City's wastewater treatment plant. — Flow is pumped from the high school lift station to a lift station at Chase Middle School, and then must be pumped through two (2) additional lift stations' near the Town of Alexander Mills (Highway 221A Lift Station and Alexander Mills Lift Station), and a large pump station near Bracketts Creek prior to treatment at the Town of Forest City VWVFP. None of these pump stations currently have adequate capacity to pump an additional 100,000 GPD of flow, with the exception of the Bracketts Creek lift station, For this alternative to be feasible, the High School, Middle School, and both Alexander Mills pumping stations would need to be replaced with higher capacity facilities to pump the additional flow. In addition, a large portion of the force mains and gravity sewer lines between the lift stations would also need to be upsized to account for the increase in flow. Preliminary calculations regarding the size of the lift station, force main, and gravity sewer upgrades are included in Appendix C. The Town of Forest City currently holds an NPDES permit to discharge 4.95 million gallons per day (MGD) of wastewater into the Second Broad River at their wastewater treatment plant. According to NCDENR Daily Monitoring Reports, current flows at the facility average approximately 4.0 MGD. It is therefore assumed for the purposes of this study that the 100,000 GPD of flow generated by the industrial park in Phase 1 will not require an upgrade to the facility. 4•0 tab> µ&D OVO- 8 4 _6 '. -1 FIGURE 3-1 F°- Alternative 2-A Pump to r °° Chase High School Lift Station Laurel �P Town of Forest City Chase Road Avenue �\ Rutherford County, North Carolina -� Chose High\ ,V, , School s z2 EXISTING \ CHASE HIGH SCHOOL 5!'

Phase 2 would also involve upgrades to the force mains constructed in Phase 1 to meet current State regulations for velocity (See calculations in Appendix C). It is assumed that the lift station wetwells constructed in Phase 1 would be designed with enough storage capacity to continue to be used in Phase 2. Therefore, the lift station upgrades would only involve the replacement of pumps in the lift stations, and related electrical upgrades. The lift stations, force mains, and gravity sewers located from the Chase High School lift station downstream would also need to be upsized to account for the increase in flow. Preliminary calculations estimating the required size of the sewer lines and lift stations are included in Appendix C. The 435,000 GPD would increase the flow at the Town of Forest City's wastewater treatment facility to approximately 90% of the current design capacity. In order to keep a reserve capacity available at the facility, it is assumed that an expansion to the plant will be constructed in conjunction with the pump station upgrades for Phase 2.

The facility is located approximately five (5) miles to the northeast of the industrial park site. The majority of the flow treated at the facility is generated at the Cone Mills Industrial plant, but the WWTP also treats domestic wastewater from the Cliffside Sanitary Sewer District. Cone Mills Corporation was contacted regarding the possibility of accepting and treating the wastewater generated at the Riverstone Industrial Park at the existing -Cone Mills WWTP. Discussions with Cone Mills Corporation have indicated that the company f" does not have the interest in receiving the flow from the park. A letter from Mr. Arthur J. Toompas, Corporate Environmental Manager of Cone Mills Corporation is included in Appendix A at the back of this report. Due to the correspondence with Cone Mills Corporation, the option of pumping the Riverstone Industrial Park flow to the Cone Mills WWTP will not be discussed further. M am on a, 13 Oft an Alternative 2-C — Connection to Chesnee, South Carolina Sewer System am The Town of Chesnee, South Carolina is located approximately four (4) am miles to the south of the Riverstone Industrial Park site. According to the South Carolina Department of Health and Environmental Control (SCDHEC), the Town OR owns and operates a wastewater treatment facility with a design capacity of 0.5 am MGD, and the facility is currently treating approximately 221,000 gallons of flow per day. The Town of Chesnee was contacted to discuss the option of pumping wastewater flow from the proposed industrial park to the Town's sewer system. Mr. Connie Nichols, Mayor of the Town of Chesnee expressed interest in accepting the flow, but noted that the Town's existing wastewater plant does not am currently have the capacity to treat the quantity of wastewater that is eventually am anticipated from the park. For the purposes of this study, it is therefore assumed that pumping flow am from the Riverstone Industrial Park to the Town of Chesnee sewer system is a 0" feasible option. It is also assumed that flow would be required to be pumped a" form the industrial park site directly to the Town of Chesnee wastewater treatment plant. This assumption is based on the fact that the Town's existing FM wastewater treatment plant has a capacity of just 0.5 MGD, and therefore, the existing sewer collection system is assumed to not have the capacity to accept a" an additional 450,000 gallons of flow per day. No costs have been included to M ffin 14 am so upgrade existing force mains, pump stations, or gravity sewer lines within the OM Town of Chesnee's existing sewer system. "M If this alternative were selected, it is assumed that flow from Chase High School would continue to be 'pumped to the Town of Forest City's sewer system. Therefore, the 15,000 GPD of wastewater that is generated at Chase High School will not be included in the total flow that would be pumped to Chesnee's VW TP. The 200 homes that are in the vicinity of the industrial park are assumed to be able to be served by the industrial park lift stations, and therefore have been included in the flow calculations. For hydraulic purposes (See calculations in Appendix C), Phase 1 consists of pumping an average daily flow of 100,000 GPD of flow and Phase 2 consists of pumping an average daily flow of 435,000 GPD of flow to Chesnee's VWVfP. am A lift station would be required to be constructed at the same location as the proposed wastewater treatment plant to collect all flow generated at the - industrial park. Due to the elevation differences observed on the USGS. Quadrangle maps for the area, the elevation difference between the lift station at the industrial park and the Chesnee Wastewater Treatment Plant would require an additional pump station to be constructed along Highway 221 in South Carolina. The preliminary design for this alternative consists of one (1) lift station on the industrial park site that pumps across the Broad River and across the North Carolina/South Carolina border, to a second lift station. The second lift ", station would pump the flow to the Chesnee VW TP. M P" 15 am AMR It is therefore assumed that two (2) submersible pump stations, each am consisting of a concrete wet well with two (2) submersible solids handling pumps, am control panel, emergency generator, and a chain link fence would be constructed so to pump the flow to the Town of Chesnee.

It is assumed that the wetwells of the lift stations constructed in Phase 1 would be sized with enough storage capacity for the increase in flow in Phase 2. Therefore, the pump station upgrades would only involve the replacement of pumps in the lift -F, stations, and related electrical upgrades. 1 17 OM The 6-inch force mains that are constructed in Phase 1 would not be sufficient to transfer the increased flow to the treatment plant. Therefore, the 6- go lines would need to be replaced with new 12-inch force mains in order to MR adequately handle the average daily flow of 435,000 gallons per day (See calculations in Appendix C). In addition to the upgrades to the lift stations and force mains, the am additional 335,000 GPD of wastewater flow for Phase 2 would be added to the Town of Chesnee's wastewater treatment plant. Based on current flows at the plant per SCDHEC (221,000 GPD), the additional total flow of 435,000 GPD would increase the total flow at the plant to 656,000 GPD. As a result, an expansion to the Chesnee VllWTP would be necessary to treat and discharge the flow. It is assumed that Chesnee would need to maintain a reserve capacity at 0" their plant to provide for future growth in the area. Therefore, a 335,000 GPD wastewater treatment plant expansion will be included in the cost analysis to treat all of the Phase 2 flow from the industrial park.

A copy of the report that was completed by Toney C. Jacobs & Associates of Mooresville, North Carolina is included in Appendix B of this report. The soil analysis report concludes that less than one-half of the soils that were studied on the industrial park site are provisionally suitable for septic systems. In addition, the report states that "the density, intensity, and flow of your proposed site will have to be drastically reduced to get an on -site option" and that subsurface systems are not feasible at the design flow. Due to the information and recommendations included in the soils f" analysis report, the option of treating the wastewater from the Riverstone Industrial Park with a subsurface system will not be discussed further. OW 014 am am 22 ALTERNATIVE NO. 5 - SURFACE WATER DISCHARGE THROUGH THE NPDES PERMIT SYSTEM This alternative consists of the construction of a wastewater treatment facility on the site of the Riverstone Industrial Park, and a discharge of the treated wastewater into the Broad River. The treatment facility would be constructed in two (2) phases — Phase 1 would involve the construction of a facility with a design capacity of 100,000 gallons per day (GPD) and Phase 2 would upgrade the facility constructed in Phase 1 to 450,000 GPD. According to information obtained from the United States Geological Survey (USGS), the Broad River has an estimated 7Q10 flow of 201 CFS = 130 MGD at the location of the proposed wastewater treatment plant. At this time, it is proposed to construct a sequencing batch reactor as the main treatment unit for the new facility. Phase 1 of the project would involve the construction of an influent pump station, mechanical bar screen with manual bypass, a pre -equalization basin, and one (1) SBR unit that would be sized to treat an average daily flow of 100,000 GPD. Treated flow from the SBR would enter a post -equalization basin, followed by chlorination and dechlorination in a chlorine contact basin, and finally would be discharged into the Broad River. Sludge from the SBR unit is proposed to be transferred to a sludge -r holding tank, and then hauled to the Town of Forest City Wastewater Treatment ' Plant for dewatering by an existing sludge dryer.

The influent pumps would need to be replaced, OR along with any necessary electrical upgrades. MR In addition, it is proposed that the Phase 2 plant would include a new influent force main, mechanical bar screen with manual bypass, and grit removal system at the head of the plant. Two (2) new sequencing batch reactors are proposed to be constructed to provide the primary treatment at the new facility. No - The existing SBR unit constructed during Phase 1 would be converted to sludge Y holding to provide for adequate sludge storage capacity at the new plant. Effluent from the SBR units would flow to a new post equalization � basin, jP11/ a*1 and then would be disinfected in a new chlorine contact basin.

These options do not appear to be economically feasible when compared to other disposal methods, based on a 20- year present value analysis. At this time, there are no known industries that are planning .to locate a facility to the industrial park that could reuse the wastewater treatment plant 40* effluent as either a process or cooling water. Using reclaimed water for toilet flushing at the facilities would still involve the construction of the wastewater treatment plant.

C. an Introduction This evaluation was made to advise the wastewater engineer and applicable State permitting agency of the soil resources and feasibility of a 450 thousand gallon per day on -site waste system, either ground absorption septic or a surface disposal system by spray or drip irrigation, along with site specific loading rate for such systems, and soil or site specifics to consider in system design. No off -site parcels were examined for potential use as waste receiver sites. This report addresses soil and site criteria for permitting through NCDENR-DEH (T 15A. 18A .1900), which includes the Rutherford - Polk -McDowell District County Health Department (RPMDHD), and also through 04 NCDENR DWQ (T 15A. 02H .0200). With these two agencies the disposal options include a subsurface ground absorption system, a surface spray or drip system, or a discharge system (NPDES), or a combination of systems. Preliminary plans are for the . 1100 acre tract is to divided into 48 parcels for development and have 208 acres in green space (Fig. 1). The green space is primarily in the buffer areas along the Broad River and its tributaries. This area is flood plain, with steeper side or lineal slopes from -the uplands to the bottomlands. Field work for this preliminary investigation was conducted in two days, November 9 and 10, 2000. This included soil and site investigation and the collection of soil maps and aerial photos of the site and adjoining properties. The soil investigation did not include participation of staff from the RPMDHD or any other State am agency. Assimilation of soil information in this report began with the Soil Suf-vey of Ruthe? ford County (Keenan, in publication). With the aid of this map and the site plan, three partial transects were made north -south across the property. Auger holes were randomly placed from 1-4 feet in depth to verify NRCS mapping and soil use capabilities. All natural cuts were examined and any tree throws were checked (Plates 1 & 2). Any other environmental features to affect land use were also noted. The primary objective of this work was to verify and expand past soil mapping to use for waste application. on G1 2 The recormnendation for either a ground absorption or surface disposal system is .. based on a combination of factors, including, but not limited to 1) topography and landscape positions, 2) soil characteristics, 3) wetness conditions, 4) soil depth, 5) soil restrictive horizons, 6) available space, 7) ability to meet setbacks, 8) affect on surface and groundwater, and 9) any nuisance factors. Generally, some of these conditions which may limit site or system use can be compensated for by modifying the system design; however, some factors cannot be remediated. It is with this philosophy that this report is prepared. This report is a supplement to an engineering design by Mr. Mike Waresak, P.E., McGill Associates, Asheville, N. C. Details required of that design have been omitted from this work. Portions of conclusions or design reconmrendations may have been modified to reflect unified efforts of soil scientist and engineer. Establishnnent of final design flow is deferred to the engineer, but this evaluation was made with a requirement for 100 thousand gallons per day initially, expanding to 450 thousand gallons per day in ., the future. Site �► The proposed industrial park is located in the south central part of Rutherford County, approximately 7 miles south of Forest City, N. C. (Fig 2). The area around the park is a mix of rural residential, moderate density residential, agricultural and woodlands (Fig. 2). All of the residential homes in the area are served by individual septic systems. Approximately 2.5 miles of property line borders Broad River to the south, a major area drainage to tine area. Broad River drainage is much of south western N. C. and the piednnont of S. C. The area is all in woods of varying degrees of salability. There is an ongoing logging operation in the central portion of the property west of Hwy. 221 (Plate 2-top). A few of the old fields that were identifiable are now grown up in small pines, briars, and other hardwoods. Much of this site is in vines and briars and is difficult to move across. A 1984 soil map and air photo (Fig. 3) is very similar to the 1993 FSA photo in Figure 4. No old homes were observed, nor were they shown on the USGS topo map. There M were numerous disturbed areas used by hunters. No time was spent locating water or 3 wastewater facilities at hunting camps. The USGS topo (Fig. 5) indicates no buildings on the property. Soils �• The site was mapped by USDA-NRCS as approximately one-half Pacolet sandy clay loam 8-15 and 15-25 percent slopes, eroded and one-half Pacolet-Bethlehem complex 2- 8, 8-15, 15-25 percent slopes, eroded. The small remainder of the tract is floodplain soils Clrewacla and Buncombe. The Pacolet is on the broad interfluves which transects the site primarily north to south. These are easily seen in Figure 3. Pacolet soils formed from mostly acidic metaniorphic rock such as granite, gneiss, schist, and sillimanite-mica schist. Pacolet soils are well drained, red or reddish yellow, have a moderate solum (usually 20-40") and have a low shrink -swell potential (Plate 1-top & 2-middle). Appendix 1 has technical information for Pacolet and Pacolet-Bethlehem Series. Plate 1- A has a typical 36" profile from this landscape. The site specific soil evaluation placed and described 20 plus subsurface profiles on the site. The inspection points were roughly field located by line of site triangulation and topo and are not shown on the site plan because horizontal control was very limited. The .. full extent of logging road -cuts along Hwy 221 was checked and used as an entry point (Plate 2-top & middle). The soils were very wet on the surface, but dry below during the evaluations. Many holes were prematurely terminated because of rock or rock fragments. Water was added to soil as needed while field evaluations were made to get accurate colors, textures, and consistencies. Soil colors indicated well -drained, highly oxidized soils in the upland positions. No low chroma mottles were noted in soil profile descriptions. Drainage mottles of two chronna or less were not observed because the lower landscape position r. was excluded from the evaluation. NRCS mapping indicates these as occasionally M flooded. Rock and weathered rock which would interfere with system performance or installation were frequently encountered, and many rocks were observed on the surface (Plates I & 2). The only minor restrictive horizons observed which could significantly limit vertical water movement and waste use was rock. Most holes had less than 40" of provisionally suitable soil in the upland and lineal slope areas. Many holes were 4 attempted that could not be placed to the prescribed (48") depth. Because of the scope of this work, saturated hydraulic conductivity (Ksat) measurements were not taken, nor were soil samples collected. Toney C. Jacobs & Associates had done an intense soil investigation for Cherokee Corporation in 1993 which included site specific work on property adjoining this parcel (Jacobs, 1993). From those measurements we would estimate Ksat of the surface horizon at 10 inches per day and the clay loam B soil horizon at 4 inches per day. Both of these values are less than the published NRCS which has a range of 48-144 inches for the topsoil and 14.4 to 48 inches per day for the subsoil (B horizon). We usually find the NRCS values to be above those values measured in the field. Our measurements were taken by the Compact Constant -Head Penneameter method described by Amoozegar (1989). Depending on the final waste disposal option, this parameter will have to be evaluated to a much greater detail. Slopes and topography are a major limitation to on -site waste disposal. The soil survey has approximately 40% of the area as D slope which is 15-25%. The heavily dissected landscape with ephemeral streams would require large aerial losses of potential available wetted areas. .. General Discussion On -site Septic ., The initial investigation identified less than one-half of the soils as provisionally suitable (PS) for ground absorption septic systems. These systems would require shallow placement and pretreatment and be difficult or impossible to permit via NCDENR-DEH. There are really no 450K gpd systems in Piedmont Carolina. These systems would utilize all the area in the upper landscape position on the site and require about 230 acres for system and required repair. Dealing with DEH and industrial wastewater would also be a tremendous challenge because of the limited DISH engineering staff. _ On -Site Spray This could be aerial or drip technology and could load the field with 0.5-1.0 inches of wastewater per week. A preliminary work -up of the best soil and landscape would indicate a required 116 to 232 acres wetted plus buffer to support the 450 thousand gallon per day design flow. Slopes would dictate the use of drip technology rather than aerial 5 spray. A project of this magnitude would be very expensive. (I just worked on one with 25K gpd that was almost one million dollars.) The site could support a small aerial spray system with a grass receiver crop (Plate 2-bottom). This pasture is adjoining on the northern property boundary. The assumptions for these numbers are based on the highest level of treatment (reuse waters). Conclusions and Recommendations The density, intensity, and flow for your proposed site will have to be drastically reduced to get an on -site option. If either of the two methods are used a much more comprehensive soil and site evaluation will be required and this soil report supplemented. A review of the USDA soil map for the area around this project indicates comparable adjoining lands, so to look at an on -site option on adjoining property appears to be futile. To keep the design flow of your proposed plan will require connecting to public or private sewer with sufficient capacity or an NPDES permit with a treatment facility. Certainly this requires a receiver stream which meets the demanding requirements of DWQ. As mentioned in the introduction, a combination of technologies, such as a conjunctive permit could be considered if flows in the Broad River are too low for this discharge. Our opinion is that on -site is not feasible at this design flow. (450,°oo 31'4) Thank you for the opportunity to be of assistance with this project. If you decide or ^ should have to reduce flow (50-100K gpd may be manageable) and need further soil investigation, let me know if I could be of assistance. If questions arise about this report by your office, the developer, or State agency, please do not hesitate to contact me at the address on the front. 6 CITED 1. Amoozegar, Aziz. 1989.
