Hi Sergei---Roger, Mike and I found quite a few discrepancies in the EAA package sent by Brooks Engineering Associates (BEA) for the Miler Apartment Complex on US Hwy 70 East in McDowell County. Listed below are some of the discrepancies: 1. Figure 1 Development Site Plan: under General Notes: mentions BUNCOMBE County (this is McDowell Co. 2. 6.0 Attachments: Attachment B- Denial letter from JACKSON County 3. Attachment A. Local Government Review Form: was sent to the City Manager but the green card was from the County Manager's office. It shows they signed it, but BEA said it had not been received. WHAT? 4. On page 1: Introduction: BEA mentions "a letter from the regional branch of the DWQ was issued October 31, 2008 stating that discharge from the sewage system was increasing fecal coliform in the stream located on the property." This letter was not included in the package. 5. BEA talks about a 2,500 gallon septic tank but on the maps it shows a 2,000 gallon tank. It appears that Brooks Engineering Associates should review their package and correct their mistalyes. y n Call if you have any questions---Thanks---Janet Aj� �� �,,�� bow(- (Sce�------------------------------------------------------------------------------------------------------------------------------------- Janet Cantwell-lanet.Cantwell@ncdenr.gov North Carolina Dept. of Environment and Natural Resources Asheville Regional Office Division of Water Quality - Water Quality Section 2090 US Highway 70 Swannanoa, NC 28778-8211 Tel: 828-296-4500 Fax: 828-299-7043 Link to "Guidebook to Water Quality Management in North Carolina": http//h2o.enr.state.nc.us/basinwide/documents/SupportDocument.pdf Link to the NC Division of Water Quality: http://www.ncwaterguality.org Link to NPDES Programs & Compliance Info: (DMRs, Annual Report, Etc.): http://h2o.enr.state.nc.us/NPDES/ Link to Technical Assistance & Compliance Unit, WW Operator Regs, Etc.: http://h2o.enr.state.nc.us/tacu/index.html Link to Collection Systems (PERCS Unit): http://www.ncwaterq ualitv.oriz/i)eres/Collection%2OSvstems/CollectionSvstemsHome.htm I Link to NC Surface Waters & Wetlands Standards ("Redbook"): http_ah2o.enr.state.nc.us/admin/rules/codes statutes.htm Link to NC Stream Classifications: http://h2o.enr.state.nc.us./bims/reports/rei)ortsWB.html Link to Water Supply Watershed Info: httpJ/h2o.enr.state.nc.us/wswp/index.html Link to booklet "Guidelines for Riparian Buffer Restoration:" http://www.nceer).net/services/euidancedoc.htm Link to Stormwater, General Permits, & Runoff Pollution: Planning & Project Management Civil Engineering Surveying l Soil Science Services Environmental Engineering & Services ENGINEERINGBROOKS ASSOCIATES 1 17 Arlington Street I Asheville NC 28801 / www.hrooksea.com 1828-M-4700 December 17, 2009 NPDES-West 1617 Mail Service Center Raleigh, NC 27606 Attention: Sergei Chernikov Regarding: Miller Apartment Complex Project No. 326409 Dear Mr. Chernikov: DENR - WATER QUALITY POINT SOURLE BRANCH Brooks Engineering Associates, P.A. appreciates the review of the Miller Apartment Complex sewer system plans and EAA package.

This letter states that the existing subsurface sand filter sewage treatment system that was permitted by the McDowell County Health Department is not providing adequate treatment of sewage. The letter also states that a permit to discharge to waters of the state as required by North Carolina General Statute 143-215(a)(1) is not held. Mr. Miller has contracted with our firm to bring the sewage discharge into compliance with state rules. The accompanying plans are for the repair of an existing surface discharge onsite wastewater system that serves an 8 unit apartment complex. The design flow is 1920 gpd. Based on the Soils Report by Walker Ferguson LSS, the site is unusable for wastewater application via surface drip, subsurface drip, or conventional system due to spatial site limitations and unsatisfactory soil depth. This report can be found in Attachment B. There is no public sewage disposal system located near the subject site. The most practical resolution to bring the site in compliance with state regulations is to provide improvements to the existing system. The site is located within the limits of the City of Marion. The improvements to the existing wastewater treatment system for the apartment complex consists of a 2500 gal septic tank (STB-446) and 3000 gallon pump tank (PT-143) by Dellinger Precast, Inc. A recirculating sand filter designed based on a 5 GPD/ft2 loading rate provides 400 ft2 of surface area for treatment. A 4:1 recirculation ratio box by American Manufacturing is used to rout % of the flow back to the pump tank via gravity flow where it is re -circulated through the sand filter. Chlorination and de -chlorination apparatus by Bio- Dynamic are used for disinfection. The tablet chlorinator and dechlorinator consists of a housing and three tablet feed tubes. Slow dissolving Blue Crystal tablets dissolve at a rate proportional to the flow providing disinfection. Bio-Max dechlorination tablets are used for the removal of residual chlorine. A contact chamber provides approximately 37.5 minutes of detention time after the chlorination apparatus. Residual chlorine is then removed after flowing through the dechorination tablet feeder device. A cascade aerator provides aeration before the effluent discharges to the stream. Final plans for the treatment system stamped "Preliminary Not released for construction" have been included. The following items have been included as Attachments in this application package: A. Two signed copies of NPDES Application Form D B. Letter from soil scientist of evaluation of subject site for suitable disposal systems. C. Specifications for all major treatment components. D. Engineering Calculations. This submittal was originally submitted and received by NCDENR- Water Quality Point Source Branch on June 8, 2009. The submittal package was returned to our office in request for additional information per letter dated June 17, 2009. As requested per that letter the following items are include in this resubmittal: Application Fee of $860.00 (Check# 1194 ); Completed Engineering Alternatives Analysis and Local Government Review Form. We appreciate your timely review of this material. If there are any questions or issues that can be resolved with an explanation, please feel free to contact me at (828) 232- 4700.

Constructors, Inc. 2024 Nix Creek Road, Suite A Marion, North Carolina 28752 Attention: Mr. Miller Regarding: Report of Findings Soils Evaluation 2041 U.S. Highway 70 McDowell County, NC Dear Mr. Miller, Walker B. Ferguson of Brooks Engineering Associates (BEA) conducted a soils investigation on a 1.34 acre tract located at 2041 Highway 70 McDowell County, North Carolina. This investigation was conducted at the request of Mr. Miller. The purpose of the soil study was to determine if any land based wastewater options were available for an eight two-bedr000m unit apartment complex. The apartment complex is currently being served by a sand filter and surface water discharge system which is in failure. Fieldwork was conducted using the following tools and methods. A 3-inch hand auger, a knife, and a sharpshooter shovel were used to examine the soil. A Suunto clinometer was used to measure soil slope. Recommendations are based on, but not limited to, observations made and data collected on topography, landscape position, parent material, underlying geology, and soil characteristics. Soil characteristics include, but are not limited to, depth to a seasonal high water table (SHWT), depth to a restrictive horizon, total soil depth, soil horizonation, soil structure, soil color, clay mineralogy, bulk density, consistence, plasticity, stone content, and percent sand, silt, clay, and mica. They follow the guidelines set forth in the North Carolina Laws and Rules for Sewage Treatment and Disposal Systems, laws amended effective December 19, 2001, and rules amended effective June 1, 2006. Grading which occurs subsequent to this fieldwork renders the soil investigation in the graded area null and void. 17 Arlington St. Asheville, NC 28801 www.brooksea.com ph.828.232.4700 fx.828.232.1331 RESULTS AND DISCUSSION + BEA found Mr. Millers tract to be unsuitable for any surface or subsurface wastewater disposal system. The site is unsuitable for a subsurface wastewater system due to a shallow Seasonal High Water Table (SHWT) and insufficient area to support the 1920 gal/per/day (gpd) design flow. This tract does not meet setback requirements for surface drip irrigation to be considered. • BEA concludes that the only feasible alternative for the 1920 gpd is a pre-treated surface water disposal system into the stream northwest of the apartment complex. Thank you for the opportunity of presenting this information to you. If we can be of further assistance, please feel free to call. Sincerely, Walker B.

Engineer's Opinion of Cost for Infrastructure G. Proposed Treatment Technology Cut -sheet 1.0 Introduction This Engineering Alternatives Analysis (EAA) is provided as part of the application for a new NPDES permit for the Miller Apartment Complex in accordance with 15A NCAC 2H.0105. The purpose of this EAA is to determine the technical and economic feasibility of wastewater disposal options available for the development. As part of the 1972 Clean Water Act, discharge to surface waters is considered only as a last resort. Brooks Engineering Associates has evaluated all of the alternatives and has concluded that the surface discharge permit is the only viable option for the applicant. The project consists of an existing 8 unit apartment complex located on a 1.34 acre parcel. The apartments have been utilizing an existing sand filter discharging to Forsyth Creek that was originally permitted by the county health department, so no NPDES permit has been issued for the facility. A letter from the regional branch of the Division of Water Quality was issued October 31, 2008 stating that discharge from the sewage system was increasing fecal coliform in the stream located on the property. A copy of the letter is provided as Attachment A. The owner has hired our firm to assist in bringing the discharge in compliance with state regulations. Upon initiation of an investigation of the soil conditions by the McDowell County Department of Public Health, it was determined that the soil was unsuitable for a land disposal system because of unsuitable soil material and setback regulations. 9.1 Applicant Information Pertinent information regarding the applicant and this application is as follows. Property Owner: NPDES Permit Applicant: Larry Miller 2024 Nix Creek Road, Suite A Marion, NC 28752 Larry Miller 2024 Nix Creek Road, Suite A Marion, NC 28752 EAA Preparers Information: Brooks Engineering Associates, PA 17 Arlington Street Asheville, NC 28801 (828) 232-4700 Contact: Paul E. Sexton, P.E. Brooks Engineering Associates, P.A. Engineering Alternatives Analysis BEA Project No. 326409 Miller Apartment Complex 1.2 Property Information The subject property is located in McDowell County near the intersection of NCSR 1536 (Memorial Park Road) and U.S. Highway 70 E, in Marion, NC. The subject site consists of one parcel (PIN # 1712-52-6802) which is 1.34 acres. The site is mostly cleared with an existing two-story 8 unit apartment building and associated asphalt parking lot. The site is bordered to the north by Memorial Park Road and bordered to the south by U.S. Hwy 70 E. Forsyth Creek runs across the property from west to east. The existing building was built in the early 1970's and has been used as a residential apartment complex. The site water service is provided by a single existing well. The site layout is provided as Figure 1. The Local Government Review Form is provided as Attachment A. A general site location map has been included as Figure 2 depicting the discharge location. The proposed wastewater receiving stream is Forsyth Creek. The design flow for the project is calculated to be 1,920 gallons per day (gpd) based upon 8 units each with 2 bedrooms at 120 gpd/bedroom in accordance with 15A NCAC 02T .0114 (since 15A NCAC 2H 0.219 has been repealed). Brooks Engineering Associates, P.A. BEA Project No. 326409 Engineering Alternatives Analysis Miller Apartment Complex 2 2.0 Initial Discharge Determination Brooks Engineering Associates has performed an initial determination regarding the potential of the receiving stream to accommodate the proposed developments' design wastewater flow of 1,920 gpd. The discharge location longitude and latitude are provided on Figure 2. The receiving stream, Forsyth Creek, was researched for limiting classifications and the following determinations were made: ♦ Forsyth Creek has no zero -flow restrictions per 15A NCAC 2B.0206 (d)(2); ♦ Forsyth Creek is classified as a Class C stream (Stream Index No. 11-25); ♦ Forsyth Creek is not designated as an Impaired Water and has no designated TMDLs; ♦ The portion of Forsyth Creek where this project is proposed has no known presence of endangered species. ♦ Class C waters have no restrictions on watershed development or types of discharges. Forsyth Creek is part of the Catawba River Basin. A basin wide plan does exist for the Catawba River Basin but Forsyth Creek is not identified in the plan. To address potential deficiencies of the receiving stream regarding flow, BEA staff conducted an investigation by confirming a positive 7Q10 "low stream flow" for Forsyth Creek with the USGS. These activities are discussed below. On June 29, 2009 BEA staff contacted Mr. Curtis Weaver, PE of the USGS in Raleigh, North Carolina. Mr. Weaver is the principal engineer in charge of making stream flow determinations for the Raleigh USGS office. The 7-day 10-year low flow (7Q10) is the governing stream criteria for wastewater point source discharges for flow acceptance. Mr. Weaver replied via e-mail that a drainage area of 0.69 sq. mi. was determined for the point of interest on Forsyth Creek downstream from U.S. Highway 70 at Clinchfield (station id 0213814220); there are three nearby partial -record sites and two continuous -record gaging stations in McDowell County and western Burke County that are in vicinity of the subject site for which low -flow discharge estimates are provided. In Table 1 of the report United States Geological Survey Water -Supply Paper 2403, ' Brooks Engineering Associates, P.A. BEA Project No. 326409 Engineering Alternatives Analysis Miller Apartment Complex 3 Low -Flow Characteristics of Streams in North Carolina' low -flow discharge estimates are provided for these nearby sites. Expressing these estimates as low -flow yields provides some indication of 7Q10 flow estimates ranging from about 0.23 to 0.45 cfs (average about 0.31 cfs). The regional low -flow relations presented in above referenced report for this hydrologic area (HA10) results in a 7Q10 low -flow estimate with yield value of about 0.28 cfsm. Applying the above stated low -flow yields to a drainage area of 0.69 sq. mi. results in 7Q10 flow estimates ranging from about 0.15 to 0.3 cfs (average about 0.2 cfs). No USGS records of discharge are known to exist for at the discharge point on Forsyth Creek. Where no or insufficient data is available for a low -flow analysis, a determination of low -flow characteristics is based on assessment of low -flow yields (expressed as flow per square mile drainage area, or cfsm) at nearby locations where such statistics have previously been determined. The low -flow characteristics that have been provided have been computed by correlating the runoff characteristics of a nearby stream in vicinity of the request site. Therefore, based upon the preliminary investigation, it appears there are no flow or water quality restrictions on Forsyth Creek that would immediately prohibit discharge of domestic wastewater with a standard level of treatment to surface waters. Brooks Engineering Associates, P.A. BEA Project No. 326409 Engineering Alternatives Analysis Miller Apartment Complex 4 3.0 Technical Evaluation of Alternatives 3.1 Connection to Existing Waste Treatment Plant Figure 3 shows a map of the closest existing Wastewater Treatment Facility which is the Marion Catawba River facility (NPDES Permit No. NC0071200). The facility is currently being assumed by the City of Marion. The closest connection point is a pump station located off of Seagle Road. The route to the pump station has approximately 68 ft of elevation gain from average elevation of the subject site. The nearest connection location to the pump station is calculated to be 0.87 mile from the subject property. BEA estimates one pump station and force main construction for the entire 0.87 miles along U.S. Hwy 70 E, secondary roads, and private property would be required to connect to this system. This facility is permitted for 0.25 MGD and the City of Marion has stated that allocation for discharge to this plant is obtainable. The allocation fees for City of Marion are included in the economic evaluation. The next closest wastewater treatment facility is the Corpening Creek WWTP (NC0020214). The facility is located approximately 6.3 miles south of the subject site. Pump stations and force mains would also be required if the sewer line were to follow federal and state roadways to the facility. The Corpening Creek facility would be extremely difficult to route a sewer connection line and is much further away than the Catawba River facility. This facility is not considered further in this evaluation. While the connection to the Catawba River WWTP collection system is possible and permittable, the distance and route required to the facility is significant and must be evaluated for the economic feasibility. This option will be analyzed in Section 4.1. 3.2 Individual or Group Septic Systems The McDowell County Department of Environmental Health performed a Soils Evaluation for the site. Upon investigating the 1.34 acre site, sufficient drainfield area for the existing building was not found. The soils were deemed "unsuitable" and the application was denied. A copy of the McDowell County report is provided as Brooks Engineering Associates, P.A. BEA Project No. 326409 Engineering Alternatives Analysis Miller Apartment Complex 5 Attachment B. Brooks Engineering Associates conducted a soils investigation to find areas suitable for subsurface disposal or surface irrigation. The entire site was determined to be unsuitable due to setback conditions and inconsistent soil properties on site. The Brooks Engineering Associates soils report letter summarizing the findings is provided in Attachment C. The setbacks from surface water, property lines, and right-of-ways and poor soil conditions render the subject site unsuitable for surface irrigation. For a community system, the 1,920 god system would require 1.32 acres for primary and repair conventional drainfield area and 0.59 acre for a community subsurface drip system. These calculated areas are based upon assumed average soil loading rates and do not include any required acreage for setbacks and any pretreatment system placement land requirements, just disposal area. Calculations are provided in Attachment D. It is estimated a 0.59 acre area would be necessary to site the drip system with the governing setbacks and allow for conveyance piping. This amount of acreage is not available at the site. Individual and/or community septic systems (including subsurface drip) are determined to not be feasible at the subject site for the following reasons. o The project soil scientist report has not identified any area suitable according to the NCAC 18A .1900 rules due to the nature of the existing soil material. o The site plan depicts no area available for on -site disposal. There is insufficient acreage available. As neither the County nor BEA found any available space on the proposed site with suitable or provisionally suitable soil conditions, all of the 0.59 acre needed for a community septic (or subsurface drip) system would have to be acquired from adjacent property owners. This option is evaluated in subsequent sections. 3.3 Land Application & Reuse A full investigation of the feasibility of a land application system typically encompasses the following evaluations: 1. Soils Evaluation (to determine saturated hydraulic conductivity rates); 2. Agronomist Evaluation (to determine nutrient balance); Brooks Engineering Associates, P.A. BEA Project No. 326409 Engineering Alternatives Analysis Miller Apartment Complex 3. Hydrogeologic Evaluation (to determine water table and lateral flow); and 4. Water Balance Evaluation (to determine storage requirements). The irrigation rate is derived from soil saturated hydraulic conductivity measurements and a water balance based upon regional rain and evapotranspiration and storage provided. Based upon other regional projects, an irrigation rate of 1 inch per week (in/wk) is an assumed reasonable irrigation rate that will not necessitate restrictions based upon hydrologic or nutrient loading. A surface drip system would require 0.50 acre of disposal area (excluding setbacks and piping) with the same 1.0 in/wk loading rate. Calculations are provided in Attachment D. To obtain the required setbacks for surface irrigation systems, a reuse quality effluent would have to be provided (NCAC 18A 2T .0900 regulations) as the wastewater irrigation rule setbacks (NCAC 18A 2T .0500 regulations) can not be met with the existing site conditions to maintain required distances from habitable structures, property lines and surface waters. If reuse quality effluent can be provided, the only applicable setback would be 25 feet from the surface waters. From a practical standpoint, BEA estimates that at a minimum 0.50 acres would be required off site to get the disposal system installed with the 1.0 in/wk loading rate. A wastewater reuse irrigation system is determined to not be feasible at the subject site for the following reasons. o The project soil scientist report has not identified any area suitable for land application due to the nature of the fill material. o The existing site conditions and improvements allow no available property for on -site disposal. o Under the NCAC 18A 2T .0900 regulations a wet weather storage pond, typically sized for 30 days of wet weather storage (57,600 gallons) must be sited and an additional pond sized for five days of storage (9600 gallons) would have to be provided to accommodate "upset" conditions. An additional 0.05 acre would be required for constructing these ponds. Again, the basic land requirements result in this disposal option as being unfeasible for the present conditions. At a minimum, an additional 0.55 acre would have to be purchased for the disposal area and for the necessary storage ponds under the 15A NCAC 18A 2T .0900 requirements. Brooks Engineering Associates, P.A. Engineering Alternatives Analysis BEA Project No. 326409 Miller Apartment Complex Additional Land Purchase The economic feasibility of purchasing additional land purchase option is evaluated in Section 4.0. From a practical feasibility standpoint, the following purchase options have been evaluated and pursued. Adjacent property owner on the southwest is Northstar Properties Limited (2.2 acres, Deed Book 485, page 708) and to the northeast is Todd J. & Lisa M. Schweiger (0.79 acre, Deed Book 829, page 575). The southwestern adjacent property is a commercial warehouse facility that consumes most of the property. The northeastern adjacent property consists of a residential home. The adjoining property owners are shown on the attached "Site Layout" map (Figure 1). None of the adjacent parcels are for sale and given the use none are likely to be for sale. Neighboring land owners were not contacted for possible land acquisition by Mr. Larry Miller. However, a PVCA is provided in Section 4.0 assuming land was available. 3.4 Direct Discharge to Surface Waters As discussed in Section 2, discharge to surface waters is found to be a technically viable option as the initial evaluation has revealed the following conditions. • Forsyth Creek has no zero -flow restrictions per 15A NCAC 2B.0206 (d)(2). ♦ Forsyth Creek has a Class C stream classification. ♦ Forsyth Creek is not designated as impaired stream and has no designated TMDLs. ♦ This section of Forsyth Creek has no presence of endangered species. 3.5 Combination of Alternatives Neither the subsurface disposal or land application alternatives are viable for the development due to unsuitable soil conditions. A combination of discharge and land application or subsurface disposal could be effective if there were a neighboring property for sale with suitable soil conditions, but this is not the case. Brooks Engineering Associates, P.A. BEA Project No. 326409 Engineering Alternatives Analysis Miller Apartment Complex 8 Therefore, the only feasible options for the development are to connect to the nearest public collection system (with a connection point 0.87 miles from the subject site), acquire neighboring property, and a surface discharge permit. Each of these options are evaluated in Section 4. Brooks Engineering Associates, P.A. Engineering Alternatives Analysis BEA Project No. 326409 Miller Apartment Complex 4.0 Economic Evaluation of Alternatives The Present Value of Costs Analysis (PVCA) for each disposal option is provided as Attachment E. The economic evaluation of alternatives is for each of the wastewater treatment options based upon the best available information. As the apartment complex is existing, no development costs are provided. Essentially the wastewater system would have to be financed by rent profits. Should the wastewater system upgrade not be within a reasonable cost, the apartment complex would be abandoned, resulting in loss of lower income housing for the community. The cost for construction and operation is calculated for the project under the following scenarios: 1) extending sewer service to the nearest existing collection system (Marion Catawba River facility); 2) a community subsurface drip system requiring additional land purchase; 3) a community wastewater irrigation system (surface drip) requiring additional land purchase; and 4) an on -site recirculating sand filter system with a surface discharge permit. Only Options 1 and 4 were determined to be feasible in Section 3.0 primarily due to site limitations and soil constraints, so Options 2 and 3 are analyzed under the incorrect assumption that the purchase of adjacent property is possible. Options 1 and 4 are analyzed without an additional land purchase as none is required. The Engineers Opinion of Cost (EOC) for the development infrastructure is provided as Attachment F. The infrastructure costs in the Engineer's Opinion of Cost are based upon professional experience and data collected on previous regional projects. As all of the infrastructure cost would be incurred in the initial year of the development, they are all considered initial costs and therefore have no time value discounting and are not included in the PVCA analysis. The owner rents all 8 units in the apartment complex. The rental price for each unit is $500 resulting in a gross annual income of $48,000. After all financing and expenses, the owner profits approximately $12,000 annually. The upgrades to the VWVTP must be able to be financed with the annual profits of the apartment complex, or else the Brooks Engineering Associates, P.A. BEA Project No. 326409 Engineering Alternatives Analysis Miller Apartment Complex 10 apartments will be abandoned, resulting in the loss of much needed affordable housing for the area. 4.1 Connection to Existing Wastewater Treatment Plant The nearest sewer connection is the Marion Catawba River facility (NC0087602) currently operated by the City of Marion .The nearest connection point to this facility is a pump station located off Seagle Road measured to be 0.87 of a mile from the subject site. The cost for the internal development sewer collection for the apartment complex is not included in the PVCA for each disposal option, but it is included in the general infrastructure costs for the development as the collection system would have to be implemented with any of the wastewater options. The references utilized for the cost basis are as follows: ♦ The price for sewer force main line is based upon professional experience and data collected on previous regional projects. This data shows the average cost for 8-inch sewer line installation is $38/foot installed. This price includes materials and labor. It is assumed this would require one pump station (as a result of the headloss in the 0.9 miles of piping) and several road bores to cross the road. This price does not include any road re -surfacing as it is assumed the line could be installed off of the edge of pavement the entire length. This may or may not be true. Any road repairs would add significant cost. The price per foot could increase to over $100 per foot should road re -surfacing be required. 6 The price for pump stations is based upon professional experience where BEA has engineered similar pump stations to NC state standards. The $150,000 price includes a diesel backup power generator. 4 The costs of the impact fees were from City of Marion Public Works. As the operation and maintenance of the WWTF, pump stations, and force main would be performed by the City of Marion and are of no expense to Larry Miller, these costs are not included in the PVCA. Sewage rates would be paid by tenants. However, the Brooks Engineering Associates, P.A. BEA Project No. 326409 Engineering Alternatives Analysis Miller Apartment Complex 11 cost of the force main and pump station installation would be assumed by Larry Miller. The route for the sewer extension analyzed is that shown on Figure 3 with approximately 0.87 miles (4,594 ft). The results of the PVCA show that the project can not possibly support the 0.9 mile sewer extension is required, which would render it not an economically viable option. This lengthy sewer extension would put undo hardship on the applicant and render his land investment worthless. The PVCA for this option is provided in Attachment E. 4.2 Individual or Group Septic Systems Individual and community septic systems are discussed in Section 3.2. Individual septic systems are determined to be not a technically feasible option. A community septic system is an option only with the purchase of additional neighboring property. While no neighboring properties are available, this option is evaluated for economic feasibility. The purchase price of $107,610 is determined from latest tax appraisal data. It is determined in Section 3.2 that a minimum of 0.59 acres of land is required for disposal plus additional acreage for set -backs and constructability. Assuming property could be purchased, the northeastern adjoining lot (0.79 acres) would provide the 0.59 acre. The cost references utilized for the PVCA are as follows: ♦ The price for the wastewater treatment system is based upon vendor pricing for a recirculating media system capable of delivering tertiary treated effluent and includes materials, installation labor, and engineering. ♦ The price for the land application drip system is based upon vendor pricing and includes materials, labor and engineering. ♦ Operation and maintenance costs are based upon professional experience, except for electrical costs which are based upon state requirements and vendor recommendations. The results of the PVCA analysis demonstrate the project can not support this option, even if any of the identified adjacent parcels are for sale. This renders this option neither technically nor financially feasible. Brooks Engineering Associates, P.A. BEA Project No. 326409 Engineering Alternatives Analysis Miller Apartment Complex 12 4.3 Reuse Land Application Individual and group land application systems are determined to not be technically feasible without additional land purchase. Section 3.3 identifies an additional minimum of 0.50 acre would be required for disposal and setbacks. Assuming property could be purchased, a portion of the adjoining northeastern lot would need to be purchased. The on -site collection and pump system are again the same for any of the treatment options and this cost is not included in the PVCA, but is considered in the return on investment analysis. The general infrastructure costs for the collection system in the development would have to be implemented with any of the wastewater options, with the exception of individual septic systems, and the cost is the same with each option, except where otherwise noted. Treatment of the effluent is to be performed by a recirculating media system capable of delivering tertiary treatment standards. The effluent is then distributed to a drip irrigation system located on the northeastern adjoining lot. The drip system will have to be dosed by an additional pump station and have a disc filtration and monitoring system. The cost references utilized for the PVCA are as follows: • The price for the extended a small aerobic packed media filtration system is based upon vendor pricing and includes materials, installation labor, and engineering. • The price for the land application drip system is based upon vendor pricing and includes materials, labor and engineering. • Operation and maintenance costs are based upon professional experience, except for electrical costs which are based upon state requirements and vendor recommendations. The results show the project can not support this option. Also, as no additional neighboring acreage is available, this disposal option is rendered not technically feasible nor financially feasible. Brooks Engineering Associates, P.A. BEA Project No. 326409 Engineering Alternatives Analysis Miller Apartment Complex 13 4.4 Direct Discharge to Surface Waters This alternative is identified as technically viable and is analyzed for economic feasibility. The Present Value of Costs Analysis is provided as Attachment E. The proposed treatment technology is a recirculating media filtration unit. The proposed plant is an E=Z Treat TM system in which septic tank effluent is dosed approximately 36 times a day over a high surface area synthetic media for aerobic biodegradation. The technology is capable of attaining tertiary treatment limits. The system has a dual treatment train to allow for duplicity in the system and provide backup treatment in an emergency situation. The system will be equipped with tablet disinfection. A brochure for this technology is provided as Attachment G. The references utilized for the PVCA are as follows: ♦ The price for the EZ-Treat system is based upon vendor pricing and includes, materials, labor, engineering, and backup power. ♦ Operation and maintenance costs are based upon professional experience, except for electrical costs which are based upon vendor recommendations. (Electrical costs for the E-Z Treat system are less than that of an extended air system as there are no blowers). The results of the PVCA demonstrate this disposal option to be economically viable with a 42% Return on Investment. 4.5 Combinations of Alternatives As all soil disposal options require the purchase of additional land, which is not available, no combinations of alternatives are deemed technically or economically feasible.

Local Government Review Form General Statute Overview: North Carolina General Statute 143-215.1 (c)(6) allows input from local governments in the issuance of NPDES Permits for non -municipal domestic wastewater treatment facilities. Specifically, the Environmental Management Commission (EMC) may not act on an application for a new non -municipal domestic wastewater discharge facility until it has received a written statement from each city and county government having jurisdiction over any part of the lands on which the proposed facility and its appurtenances are to be located. The written statement shall document whether the city or county has a zoning or subdivision ordinance in effect and (if such an ordinance is in effect) whether the proposed facility is consistent with the ordinance. The EMC shall not approve a permit application for any facility which a city or county has determined to be inconsistent with zoning or subdivision ordinances unless the approval of such application is determined to have statewide significance and is in the best interest of the State. Instructions to the Applicant: Prior to submitting an application for a NPDES Permit for a proposed facility, the applicant shall request that both the nearby city and county government complete this form. The applicant must: ■ Submit a copy of the permit application (with a written request for this form to be completed) to the clerk of the city and the county by certified mail, return receipt requested. ■ If either (or both) local government(s) fail(s) to mail the completed form, as evidenced by the postmark on the certified mail card(s), within 15 days after receiving and signing for the certified mail, the applicant may submit the application to the NPDES Unit. ■ As evidence to the Commission that the local government(s) failed to respond within 15 days, the applicant shall submit a copy of the certified mail card along with a notarized letter stating that the local government(s) failed to respond within the 15-day period. Instructions to the Local Government: The nearby city and/or county government which may have or has jurisdiction over any part of the land on which the proposed facility or its appurtenances are to be located is required to complete and return this form to the applicant within 15 days of receipt. The form must be signed and notarized.

Brooks Engineering Associates Land Planning Civil Engineering Surveying Environmental Services Soil Science Services April 22, 2009 Larry Miller G.E.M. Constructors, Inc. 2024 Nix Creek Road, Suite A Marion, North Carolina 28752 Attention: Mr. Miller Regarding: Report of Findings Soils Evaluation 2041 U.S. Highway 70 McDowell County, NC Dear Mr. Miller, Walker B. Ferguson of Brooks Engineering Associates (BEA) conducted a soils investigation on a 1.34 acre tract located at 2041 Highway 70 McDowell County, North Carolina. This investigation was conducted at the request of Mr. Miller. The purpose of the soil study was to determine if any land based wastewater options were available for an eight two-bedr000m unit apartment complex. The apartment complex is currently being served by a sand filter and surface water discharge system which is in failure. Fieldwork was conducted using the following tools and methods. A 3-inch hand auger, a knife, and a sharpshooter shovel were used to examine the soil. A Suunto clinometer was used to measure soil slope. Recommendations are based on, but not limited to, observations made and data collected on topography, landscape position, parent material, underlying geology, and soil characteristics. Soil characteristics include, but are not limited to, depth to a seasonal high water table (SHWT), depth to a restrictive horizon, total soil depth, soil horizonation, soil structure, soil color, clay mineralogy, bulk density, consistence, plasticity, stone content, and percent sand, silt, clay, and mica. They follow the guidelines set forth in the North Carolina Laws and Rules for Sewage Treatment and Disposal Systems, laws amended effective December 19, 2001, and rules amended effective June 1, 2006. Grading which occurs subsequent to this fieldwork renders the soil investigation in the graded area null and void. 17 Arlington St. Asheville, NC 28801 www.brooksea.com ph.828.232.4.700 fx.828.232.1331 RESULTS AND DISCUSSION • BEA found Mr. Millers tract to be unsuitable for any surface or subsurface wastewater disposal system. The site is unsuitable for a subsurface wastewater system due to a shallow Seasonal High Water Table (SHWT) and insufficient area to support the 1920 gal/per/day (gpd) design flow. This tract does not meet setback requirements for surface drip irrigation to be considered. • BEA concludes that the only feasible alternative for the 1920 gpd is a pre-treated surface water disposal system into the stream northwest of the apartment complex. Thank you for the opportunity of presenting this information to you. If we can be of further assistance, please feel free to call. Sincerely, Walker B.
