POLLUTANT ANALYSIS CONDITION The Permittee shall conduct a test for pollutants once every five years at the effluent from the treatment plant. The discharge shall be evaluated as follows: A. A pollutant analysis of the effluent must be completed using EPA approved methods for the following analytic fractions: • purgeables (i.e. volatile organic compounds); • acid extractables; • base/neutral extractables; • organochlorine pesticides and PCBs; • herbicides; and • metals and other inorganics. The Pollutant Analysis Monitoring (PAM) Requirement Reporting Form A and accompanying memo, to be provided to all discharges impacted by this monitoring requirement, describes the sampling and analysis requirements and lists chemicals to be included in the pollutant analysis. B. Other significant levels of synthetic organic chemicals must be identified and approximately quantified. For the purposes of implementing this requirement, the largest 10 GC/MS peaks in the purgeable, base/neutral extractable, and acid extractable fractions (or fewer than 10 if less than 10 unidentified peaks occur) for chemicals other than those specified on the PAM reporting form should be identified and approximately quantified as stated in the aforementioned reporting form. This part (item B) of the PAM requirement is to be referred to as the "10 significant peaks rule". Vaughn&Melton 219 West Depot Street Greeneville, Tennessee 37743 Tel. (423) 639-0271 FAX.

Wastewater collected by the regional sewer system will be received at the plant's headworks by a 12" gravity line. Influent wastewater will go through a proposed comminutor (Muffin Monster or equal) where solids and other large size material will be ground. The existing manually cleaned bar screen will remain and serve as an overflow channel. The ground wastewater will flow into the upgraded headwork's pump station and be transferred to the new WWTP. Pumped influent from the headworks pump station will be directed into an oversized extended activated sludge operation unit (oxidation unit) engineered to remove biological suspended, colloidal and dissolved matter from the wastewater stream. The oxidation' unit, which will be operated with long hydraulic detention times, high solids retention times, and low organic loading rates, will provide low-cost treatment, reliable performance and operation simplicity. Effluent wastewater from the extended activated sludge unit will then be processed by two circular center feed secondary clarifiers. All solids and suspended growth biomass leaving the oxidation ditch with the effluent stream should be removed at this location prior to effluent discharge. Sludge withdrawal and return will be employed from the bottom of the clarifiers and collected at the RAS pump station for visual inspection prior to further treatment. Two pumps with 400 gpm capacity each (800 gpm total) will be provided. Part of the sludge will be wasted into the digester while the remaining sludge will be recirculated back into the oxidation ditch to maintain the desired MLSS concentration. Digested sludge from the aerobic digester (minimum detention time of 45 days) will be fed into a proposed sludge filter belt press for additional thickening and dewatering. Supernatant from the filter belt press and the digester will be recirculated back into the RAS pump station and eventually into the oxidation ditch. Before the treated wastewater is discharged into the North Toe River, it will be disinfected using the proposed ultraviolet light disinfection system. The flow rate of the treated wastewater will be recorded at the proposed effluent flume prior to its release to North Toe River. Influent and effluent samplers will be provided next to the flow measuring structures for monitoring and compliance purposes. V&M # 29901-01 ENGINEERING ALTERNATIVES ANALYSIS NEWLAND, NORTH CAROLINA WASTEWATER TREATMENT PLANT EXPANSION April, 2003 (Revised October, 2003) - Prepared By - VAUGHN & MELTON 1318-F Patton Avenue Asheville, North Carolina 28806 V&M Project No. 30024-01 I. GENERAL INFORMATION A. Provide Basic Identification of the Project: Name of Facility County Facility Address Facility Telephone Number EAA Preparer Town of Newland Wastewater Treatment Plant Avery P.O. Box 429 Newland, NC 28657 (828) 733-2023 Vaughn & Melton 1318-F Patton Avenue Asheville, NC 28806 Contact: Mike Calhoun, P.E. (828) 253-2796 M. Wayne Robertson, P.E. (423) 639-0271 B. Project Description & Flow Calculations: The Town of Newland is planning an upgrade of its Wastewater Treatment Plant from 0.32 MGD capacity to 0.60 MGD (Please see Appendix for a location map). As early as 1997, the Town of Newland received a Notice of Violation for having exceeded 80% of their permitted capacity. In March 1998, the Town of Newland was cited for overflows which had occurred at its main pump station bar screens. In March, 2001, the Town received a Notice of Violation for exceeding its permitted capacity. Please see copies of these Notices in the Appendix. The Town of Newland's WWTP has exceeded its design capacity on numerous occasions for several years. As a result, a design was developed to provide the WWTP with sufficient capacity for the expected growth of the next 20 years. That design process is outlined in the following sections. Population: According to North Carolina State demographic information, the population of the Town of Newland was 724 in 1998 (See data in Appendix). That population grew 9.6% from April 1990 to July 1998, which represents an approximate growth rate of 1.2% per year. If the project is assumed to be completed in 2004, population figures for 20 years beyond that (2024) are estimated as follows. Projected Population = 724 (1.012)1\2 PROJECT #30024-01 10/03 PAGE 1 In addition to the growth expected in the Town of Newland, there are other potential sources of growth. There is a good chance that a new, 300 unit subdivision will be developed in the area within the next few years. In addition, the Town of Mt. Glenn has expressed an interest in connecting to the Town of Newland's system. Infiltration & Inflow: Infiltration and inflow were addressed as part of the designed upgrade as well. An estimated I&I flow of 148,100 GPD was calculated as shown in the Appendix. To combat the problem of I&I, extensive sewer rehab is underway in a related project to the WWTP upgrade. This project involves the rehabilitation of approximately 10,000 feet of sewer lines in the Town of Newland. The rehabilitation project should be completed prior to plant construction. Flow: NCAC T15A: 02H. 0219 stipulates a minimum design flow of 120 gpd per bedroom, with a minimum flow per dwelling of 240 gpd. Additional bedrooms se that flow by 120 gpd. To simplify the calculations, an average flow of d/customer was assumed. The sewer system currently serves 500 residential and commercial customers. Assuming that a population growth rate of 1.2% per year will apply to customers and that the upgrades will be completed in 2004, the number of customers expected in 2024 is calculated as follows. Projected customers = 500 (1.012)^2 A summary of the determination of the upgraded plant capacity of 0.600 MGD is given in Table 1. TABLE 1 Description Flow (GPD) Maximum average monthly flow (past 2 years) 380,000 Customer Growth (150 customers @ 270 GPD) 40,500 Reserve (25% of maximum monthly flow) 60,000 Commercial Flow (18% of total future flow) 60,000 Future I&I ((.15) (165,500qpd)) 24,075 Total Required Capacity 564,575 Design Capacity 600,000 Peak Flow Rate (2.5 peaking factor) 1,411,437 PROJECT #30024-01 10/03 PAGE 2 Flow restriction devices could possibly reduce the total flow. However, as nearly all of Newland's customers are private residences and businesses, implementation and enforcement of a flow reduction program and would be extremely difficult. Any flow reductions would be small at best, and due to the large uncertainties in forecasting flow, construction economics would dictate that the plant be designed and constructed for at least a 0.600 MGD capacity. C. Existing Facilities: The existing plant has a design flow of 0.32 MGD. Two modular contact stabilization units consist of an aeration basin, a secondary clarifier and an aerobic digester. Other components of the existing plant include an influent flow splitter box and influent flume, a chlorination / dechlorination basin, a sludge holding tank, sludge drying beds, a filtrate pump station, three positive displacement blowers and other controls and equipment necessary for the operation. Some of this equipment is 35 years old and has reached the end of its operational life. The proposed WWTP upgrade will utilize both existing components and new construction. The completed plant will consist of two oxidation ditches, two secondary clarifiers, a RAS pump station, a dewatering building with a belt filter press, and an ultraviolet disinfection system. The existing modular contact stabilization units will be modified and utilized as aerobic digester basins. All construction will occur on the existing site of the WWTP; no new land will be acquired. See Appendix for diagrams of the process and site plans of the existing and proposed conditions. A design report will be submitted with the application for an "Authorization to Construct" permit after an NPDES permit is obtained. In addition to the proposed upgrade at the WWTP, improvements at the headworks pump station are also included in the proposed project. A series of 4" to 12" sewer lines and pump stations convey flow to the headworks pump station, which is located approximately 0.5 miles away from the WWTP. This pump station will be upgraded with the addition of a new, 10' diameter wet well and two new pumps. The new wet well will provide additional storage capacity. See the Appendix for diagrams of the existing and proposed headworks. It is anticipated that the work at the WWTP and headworks pump station will be completed as one project. The existing WWTP and headworks will be kept operational during construction. No phasing of construction is expected. D. Phases: No phasing of work is planned. PROJECT #30024-01 10/03 PAGE 3 II. DISPOSAL ALTERNATIVES Several alternatives for disposal of the effluent from the proposed upgraded WWTP were explored as described in the following sections. • Connecting to a Publicly Owned Treatment Works (POTW) • Connecting to a privately owned treatment works • Feasibility of individual subsurface systems ■ Feasibility of community subsurface systems • Drip irrigating — both surface and subsurface • Spray irrigating • Reuse ■ Surface water discharge through the NPDES program • Any possible combination of the above options A. Connection to a Publicly -Owned Sewer -Collection System: The Town of Newland operates the largest sewer collection and treatment system in Avery County. Other permitted treatment plants located within approximately five miles of the Town of Newland and their permitted capacities are listed in Table 2. TABLE 2 (Source: http://h2o.enr.state.nc.us/NPDES/documents/docs/permits2.xls) Owner Facility Avery Development Corporation GGCC Utility Inc Linville Land Harbor Prop. Owners Assoc. Linville Resorts, Inc Linville Ridge Country Club NC DENR Town of Crossnore Town of Newland Mountain Glen Golf Club GGCC Utility Incorporated Linville Land Harbor Poa Linville Resorts Incorporated Linville Ridge Country Club Corpening Training Center Crossnore WWTP Newland WWTP Permitted Capacity 6,000 70,000 225,000 100,000 15,000 18,000 70,000 320,000 The nearby treatment facilities are primarily package treatment plant systems which are not designed for treating high volumes of residential and commercial sewage. The largest facility, owned by the Linville Land Harbor Property Owners Association, has a permitted flow which is only 28% of the required flow to treat waste streams from Newland. No known expansions of any of the listed treatment facilities is expected to occur in the next five years. PROJECT #30024-01 10/03 PAGE 4 B. Land -Based Disposal: Several types of land disposal systems for treated effluent are available, including low pressure pipe systems, drip irrigation, and spray irrigation systems. However, all of these have a similar drawback when being applied to large effluent flows such as those found in this project: Land disposal requires large areas of suitable land. Identification of sites for small systems (<1.0 MGD) is usually much less complicated than that for larger systems. However, due to the steep slopes of available land near Newland, available sites are very limited. The search begins at the point of wastewater collection and radiates outward until one or more potentially suitable sites have been located. The sites may be identified with the following desirable features: 1. Fairly large tracts of undeveloped land or farms under a single ownership. 2. Land that is now or has been farmed, or is forested. 3. Location is relatively near point of wastewater collection. 4. Groundwater is more than loft (3m) deep or there is a nearby water body that could be used to receive the under drainage needed to lower the water table and to receive the percolated effluent. 5. Land that is already for sale or that can be bought with reasonable negotiations. 6. Zoning that is compatible with land treatment facilities requirements, such as areas zoned for greenbelts. 7. Existing irrigated lands (e.g., golf courses, parks, highway landscaping). 8. Access from developed roads and adequate power supply. At this point in the site investigations neither the land treatment process nor the total land area is known. In order to make some initial assessment of the sites, some preliminary estimate of area is needed. Guidelines to land area needs for preliminary site identification are provided. These values are for estimating purposes only and must be refined before any final design. These lands needs come from EPA Design Manual for Land Applications of Municipal Wastewater. PROJECT #30024-01 10/03 PAGE 5 1) Surface Disposal: Surface disposal considered was over -land flow and high rate spray irrigation. Based on the EPA Design Manual, spray irrigation or other surface disposal option would not be a viable without large holding lagoons. Cold winters would prevent the systems from -operating during much of the winter. A temporary pond to contain the flow from the plant for 60 days could be sized as follows: 600,000 gal/day * (40 days) * (0.133 ft^3/gal) = 3,192,000 ft^3 The above flow would require approximately 10 acres of land with average pond depth of 10 feet with 1.5 feet of free board. PROJECT #30024-01 10/03 PAGE 6 2) Subsurface Disposal: Because of their large land requirements, subsurface disposal options such as drip irrigation are best suited to relatively small flow unless large tracts of suitable land are available. This land should be level, have good permeability, and have a fairly large depth of soil above the first impermeable layer. The soils found at the WWTP site, as identified in the Environmental Report, dated August 18, 2002, and prepared by the Region D Council of Governments and Vaughn & Melton Consulting Engineers, are Nikwasi sandy loam, Porters loam, Warne fme sandy loam, and Watauga loam. A brief description of each of these soils types follows: Soil description has been included in Appendix I. Jim Watson, Environmental Engineer with the Tennessee Valley Authority in Chattanooga, was contacted for information regarding drip irrigation systems. All information utilized in the following calculations was provided by him. An average infiltration rate for silty loam is 0.2 gal/day/ft^2. Based on that estimate, which would need to be confirmed by detailed soils analysis, the land required is calculated as follows: (600,000 gal/day) / (0.2 gal/day/ft^2) = 3,000,000 ft^2 / (43,560 ft^2/acre) = 69 acres DENR requires a 100% reserve area for subsurface disposal systems, so the land required is: (69 acres) * 2 = 138 acres The Town of Newland owns only 7 acres at the WWTP site. The land surrounding the plant is steeply sloped toward the North Toe River. As much of this land would be within the flood plain, it would be unacceptable for subsurface disposal. In addition, since steeply sloping soil is less suitable to subsurface disposal, even more land would likely be required. Even if the land were available, costs of a subsurface disposal would be prohibitive. In addition to the initial cost of the land, a subsurface disposal system requires piping for emitters spaced on 2' centers, pumps, valves, and other control systems must be installed. A typical cost for a subsurface system with a flow on the order of 0.25 MGD is $4.00 per gallon/day. Economies of scale could reduce this cost. PROJECT #30024-01 10/03 PAGE 7 However, even if the installed price were $2.00 per gallon, the resulting cost would be: 600,000 gal/day * ($2.00/gal/day) = $1,200,000 Plus transport cost to nearest suitable site approximately 50,000 linear feet from treatment plant pump station location, at an estimated cost of $8.00/LF, this would be $400,000.00, plus the required 3 pump stations @ $80,000/Each or $240,000 making a total construction cost of $1,840,000, not including primary treatment plant cost. This amount represents about 85% of the total expected project cost of $2,300,000 as estimated in the Preliminary Engineering Report dated April 28, 2000. Due to this factor and the unavailability of land, this does not appear to be a viable option. C. Wastewater Reuse: Because no other facilities are located at or adjacent to the WWTP, there are no uses for this amount of effluent on site. The WWTP is located in a rural area with no large users such as golf courses nearby. The nearest golf course is approximately 9 miles from the treatment plant site or 50,000 LF. The transport cost would be the same as in item (B) or $640,000 plus $1,700,000 in facilities improvement for pretreatment. D. Surface Water Discharge: 1. The existing WWTP currently is permitted under NPDES Permit #NC0021857 to discharge up to 0.32 MGD to the North Toe River. Speculative effluent limits for the proposed expansion to 0.80 MGD were granted by the NC DENR in a letter dated May 4, 2001 (See Appendix). In that letter, the summer 7Q10 flow for the river at the location was estimated as 3.3 cfs. 2. No tertiary filters have been considered due to their high cost and the lack of a need for tertiary treatment to meet the discharge limits. A detailed design report will be submitted with the "Authorization to Construct" application. 3. A diagram of the proposed discharge system including outfall lines is included in the Appendix. The discharge system includes approximately 400' of 14" gravity sewer line running from the secondary clarifiers to an existing manhole. From here, the effluent utilizes the existing 12" gravity discharge line to the North Toe River. Along this line, a new UV system (Trojan System UV 3000B or equal) will disinfect the effluent, and a new Parshall flume will monitor and record discharge flows. PROJECT #30024-01 10/03 PAGE 8 4. No additional land acquisition will be required for this option. The upgrades will require approximately one-half acre of additional land; this land is already owned by the Town. No additional staff cost will be incurred. The discharge will not require that any additional staff be hired. 5. Present Valve Cost Analysis: The present valve analysis is outlined in the following: PROJECT #30024-01 10/03 PAGE 9 TABLE 3 Plant Construction Cost Plus Operation & Maintenance for 20 years @ 4.5% interest. 2,290,000 + $50,000/year Present Worth Factor =13.0263 Present Worth = $2,941,312.50 Total Capital Cost + Operation & Maintenance $2,500,000 + $50,000/year Total Present Wo Rural Development fundinuments are attached. E. Disposal Combinations: Since none of the disposal alternatives except surface water discharge is feasible, no combination of alternatives will be practical to increase capacity of existing treatment facilities. From available information, surface water discharge is the only viable alternative. No private or public sewer systems of a suitable size are located within five miles of the Town of Newland's WWTP, and no upgrades of any of the existing WWTP's have plans for upgrades. Land -based systems would require nearly 60 plus acres of suitable land, but only a few acres of land are available at the site. No reuse of the effluent is possible because there is no need for that quantity of effluent at the site of the WWTP or nearby. A combination of these options is not feasible since none of the individual options are suitable. The most viable environmental or economic alternative is to provide treatment to meet proposed limits and use surface water disposal into the North Toe River.

This Rule specifies that no permits for sewer line extensions will to issued by the Division of Water Quality to facilities exceeding 80% of their hydraulic treatment capacity unless specific evaluations of futiur wastewater treatment needs have been completed. A review of your self -monitoring reports has indica±ed that the subject facility exceeded the 80% value for calendar year 1997. The average flow calculated for this period was 0.2612 MGD, and repitsented 81.62`70 of the current treatment capacity. Therefore, we will be unable to approve any further sewer line extensions for this facility until such time as you have complied wide' the requirements.contained in the Rule. In order to remain in compliance with the Rule., you must submit an approvable engineering evaluation of future wastewater treatment needs. This evaluation must outline specific plans for system expansion and including the sources- of funding for the expansion. If future expansion is not proposed, a detailed justification must be made based on past growth records and future growth projections and, as appropriate, shall include conservation plans or other specific measures to achieve waste flow reductions. To prevent delays in the processing of your future permit applications for sewer Line extensions, please submit a plan of action containing the -information necessary to comply with the appropriate demonstrations as described above to the following address: P.O.

Re*ulrtcrs The Honorable Beatrice Daniels, Mayor Town of Newland Post Office Box 429 Newland, North Carolina 28657 Subject: NOTICE OF 'VWL TION Illegal Discharge of Wastewater Sewer Line Overflows Town of Newland Avery County Dear Mayor Daniels: The Division of Water Quality has recently received several complaints concerning the overflow of wastewater from the Town of Newland's sewerage system at the bar screen unit at the Town's main pump station. On February 17, 1998, Mr. Mike Parker, Environmental Chemist, Division of Water, discussed this matter with Mr. C. L. Lewis at the Town Hall and asked him to investigate this matter and to submit information concerning the overflows on the Sanitary Sewer, Pump Station and WWTP Spill or Bypass Report Form. In September 1997, the Town of Newland was sent a letter from Mr. Preston Howard, Director, Division of Water Quality, outlining.the reporting requirements for wastewater overflows and bypasses. A copy of the reporting form was included with Mr. Howard's letter. For your information I am enclosing another copy of the reporting requirements. After receiving additional complaints concerning wastewater overflows from the pump station area, Mr. Parker conducted an investigation on March 13, 199B. The results of that investigation found that the concrete structure housing the bar screens had recently overflowed and there was also evidence of an overflow from the manhole between the bar screen structure and the main pump station. It appears that these sewerline overflows made their way to the North Toe River, Class C--trout waters. 59 Woodfin Place, Asheville, North Carolina 28801 Telephone 704-251.6208 Fax 704-251-6452 An Epusl Opportunity AtfittnitiVs Action ErrlpiaWar Honorable Beatrice Daniels March 20, 1998 Page Two These overflows onto the ground and into state surface waters constitute a violation of N. C.. General Statute 143-215.1 (a)(1), by creating an outlet into waters of the State without a permit. The Town of Newland is also in violation of NPDES Permit No. NC0021857, Part II, Section C. 4. c. for failure to notify the Division of Water Quality of these bypasses. These violations may result in enforcement actions being taken against the Town of Newland. . This is a very -serious situation that could result in health hazards to persons coming into contact with untreated sewage and should be considered as an emergency any time a sewerline overflows. It is requested that the Town of Newland submit a written response to this office by March 31, 1998, explaining what caused the overflows, providing records of all sewerline overflows since October 1, 1997,(en the sewerline overflow reporting form), an explanation as to why these overflows were not reported to the Division of Water Quality and the actions the Town is taking to prevent future overflows. If you have questions, please contact Mr. Mike Parker at 704/251-6208. Sincerely, Roy M. Davis, Regional Supervisor Division of Water Quality xc: C. L. Lewis Don Safrit Avery County Health Dept.

I/I determination: The reported daily flowrate to the Newland Wastewater Treatment Plant was plotted versus time on the attached graph. The theoretical wastewater production rate was subtracted from all the reported flowrates during the last two years. The number of days flow exceeded the 112,500 GPD theoretical wastewater production rate was 384. The difference between the reported daily flowrate and the theoretical wastewater production rate is the daily I/1 contribution. The total (cumulative flow in excess of 112,500 GPD) I/1 contribution during those 384 days was 56.863 million gallons. 3.

Only a few cost figures are actually presented, but references are made to specific sources of cost information. Because the cost effectiveness of land treatment is sensitive to land cost, a separate discussion for estimating this item is included. Methods of evaluating revenues and a discussion of tradeoffs that are unique to land treatment cost analysis are also discussed. 3.7.1.1 Capital Costs Curves for capital costs are available in Costs of Wastewater Treatment by Land Application [48] .The Stage II curves are recommended in conducting cost estimates. Although the base date for these curves was February 1973, they should not be arbitrarily updated by conventional cost indexes. A comparison of unit costs for key items, such as earthwork and continuous -move sprinkling equipment, may provide a more reasonable estimate of the increase in current local prices over the prices of February 1973 [49] . Components that might be used for preapplication treatment include primary sedimentation and aerated lagoons. Their capital costs can be determined from published cost curves for conventional treatment systems [50, 51], recent construction bids, and current price quotations, as necessary. Additional cost estimating data have beer. published for aerated lagoons because they are commonly used in conjunction with land treatment systems [48, 52]. Costs should include sludge handling as well as liquid processing components. A checklist of the items requiring a capital cost estimate is provided in Table 3-13. These should be completed for each alternative system. Salvage values at the end of the planning period for structures and equipment should be based on expected service life. Appendix A of 40 CFR 35 [45] specifies service lives to be used in Section 201 facilities planning (under PL 92-500) as follows: Land Structures Process equipment Auxiliary equipment 3-45 Permanent 30 to 50 years 15 to 30 years 10 to 15 years TABLE 3-13 CHECKLIST OF CAPITAL COSTS FOR ALTERNATIVE LAND TREATMENT SYSTEMS [48] Alternative No. Type of system Average flow mgd Analysis date Total Amortized cost, $ cost $/yr Preapplication treatment Transmission Storage Mgal Field preparation Recovery Additional costs SUBTOTAL Service and Interest factor at % SUBTOTAL Land at /acre TOTAL a.

However. if proper annual maintenance is practiced, figure only interest on the leveling costs. Use interest on capital invested in water right purchase. d. Except where silting from watershed above will fill reservoir in an estimated period of years. 3-47 3.7.1.2 Annual Operation and Maintenance Costs Operation and maintenance costs include labor, materials and supplies, and power costs. They may be assumed constant for the planning period though many of the costs will vary throughout the period, particularly those which are flow -dependent, such as power costs for aeration and pumping, and chemical costs. if flows are expected to increase substantially during the planning period, varying operation and maintenance costs should be analyzed on a year -by -year basis (life -cycle cost) or by reducing the total future value of the increasing annual costs to an equivalent annuity amount. Preapplication treatment will require operation and maintenance labor, materials including chemicals, and power costs. These costs can be determined from cost estimating sources for conventional treatment processes [50, 51, 54]. Additional operation cost data on aerated lagoons can be obtained from other sources [48]. Operation and maintenance costs for the remaining categories can be found in reference [48]. A checklist has also been prepared for operation and maintenance cost estimating purposes and is shown in Table 3-15. 3.7.1.3 Land Costs 3.7.1.3.1 Fee -Simple Purchase The land category includes the cost of acquiring land for application sites, buffer zones, service roads, storage reservoirs, preapplication treatment facilities, administrative and laboratory buildings, and other miscellaneous facilities. Easements for transmission pipelines may also be included in this category. Land for preapplication treatment facilities and other permanent structures is usually purchased outright if it is not already under control of the wastewater management agency. Several options are potentially available for acquisition or control of the land used for the treatment process. These include outright purchase (fee -simple acquisition), long-term lease or easement, and purchase with leaseback of the land with no direct involvement in the management of the land. A separate option of simply negotiating contracts with private landowners to sell or deliver wastewater for application would eliminate land acquisition as a capital cost. According to a recent survey, fee -simple land acquisition is preferred by most states, communities, and federal agencies [55]. Purchase of the land provides the highest degree of control over the application sites and ensures uninterrupted land availability for both short-term and long-term planning. In many cases, 3-48 TABLE 3-15 CHECKLIST OF ANNUAL OPERATION AND MAINTENANCE COSTS FOR ALTERNATIVE LAND TREATMENT SYSTEMS [48] Alternative No. Type of system Average flow • Mgal/d Analysis date Annual Cost, $ Labor Power Material Total Preapplication treatment Transmission Storage Mgal Distribution Recovery Additional costs Revenues SUBTOTAL Land lease TOTAL a. Section 3.7.1.4 purchase will be more economical than leasing or easements. For this option, land acquisition is treated as a simple capital expenditure. For projects eligible for PL 92-500 construction grant funding, purchase of land to be used as an integral part of the treatment process is eligible. Purchase and leaseback of land for agricultural 3-49 or other use involving application of wastewater would require an initial capital expenditure and annual revenues, or negative operation costs, as discussed in a later section. Assuming that land is purchased, the capital cost is determined simply by multiplying the total area required by the prevailing market value. Methods of estimating the total area required have been discussed in Section 3.3. Because the final altematives usually include specific sites, the prevailing market value can be estimated from information supplied by a local source, such as the tax assessor's office. In a few cases, the wastewater management agency may already control sufficient land and acquisition is therefore eliminated as a capital cost factor. The costs of relocating residences and other buildings must be included in the estimate of initial costs and are highly dependent on the location. Agencies such as the U.S. Army Corps of Engineers, U.S. Bureau of Reclamation, and state highway departments can assist in the estimates. For federally funded projects, the acquisition of land and relocation of residents must be conducted in accordance with the Uniform Relocation Assistance and Land Acquisition Policies Act of 1970. In one case, relocation costs for moving approximately 200 families averaged about $5 000 per family, plus about $300 000 for administration of the program [42]. EPA guidelines require that the salvage value of land be assumed equal to the initial purchase price. Land values may, in fact, appreciate considerably during the planning period, particularly if relatively undeveloped land is purchased initially. 3-50 ' V4/ 11 / 1be;i 14: 21 l932669 NEWLAND PAGE 02 Name of Applicant TGWU of Newland GRANT DETERMINATION `. 1rtate NC Try OF SERVICE : Sewer Plant Expansion and line Work 1.

These characteristics and the required effluent quality requirements will combine to suggest the type of land treatment process that should be used. *EPA Publication — 625/1-77-008 6-6 Site characteristics that should be noted include the following: 1 Soils --type, distribution, permeability of most restrictive layers, physical and chemical characteristics, and depth to groundwater 2. Available land area, both gross and net areas (i.e., excluding roads, rights -of -way encroachments, stream channels, and unusable soils) 3. Distance from source of wastewater to site, including elevation differential 4. Topography, including relief and slopes 5. Proximity of site to industrial, commercial, residential developments; surface water streams; potable water wells; public use areas such as parks, cemeteries, or wildlife sanctuaries 6. Present and future land uses 7. Present vegetative cover 6.2.4 Select Land Treatment Process The selection of the appropriate unit process depends primarily on the following two conditions: 1. Soil characteristics at the prospective site 2. The requirements of the discharge permit or groundwater quality Obviously, other conditions such as other site features, total land area, operating personnel, and related economic and environmental factors, combine to help form the final conclusion. A decision matrix for forming preliminary conclusions on the land treatment process based on technical considerations only is presented in Table 6-6. Other related conditions can then be used to finalize the decision. The preferred land treatment options for small systems are, in order: slow rate, rapid infiltration, and overland flow. Other treatment processes have been used to treat wastewater in research and demonstration projects but applicable design criteria are not generally available. Slow rate systems are the first design choice because of the similarity to normal agricultural practices, and their performance is the least sensitive to operational changes so that treatment reliability under variable conditions is greatest Rapid infiltration systems are 6-7 PRELIMINARY SELECTION OF LAND TREATMENT SYSTEMS Levels of effluent quality (NPDES permit), mg/L Range of soil permeability, in./ h <0.06 0.06-0.2 0.2-0.6 0.6-2.0 2.0-6.0 6.0-20.0 >20.0 g3OD=4 <SS = 2 <N = 4 <P = 0.1 Slow rate Slow rate Slow rate Slow rate g3OD = 5 .

Discharge to groundwater or indirect discharge to surface water. 1 in./h = 2.54 cm/h the second choice in small scale systems because removals of most wastewater components are excellent with low operation and maintenance requirements. A consistent level of nitrogen removal, however, is more difficult to obtain than with other systems. In some groundwater aquifers nitrogen content is of little concern, greatly enhancing the use of rapid infiltration systems. Overland flow systems require the greatest level of on -site management to maintain high levels of treatment so extra operator training is required, particularly for proper maintenance of the terraces. After selecting the unit process, the required "wetted" or application land area can be computed. In general, this calculation requires development of the hydraulic application rate and the duration of application during the year. It also requires consideration of additional applied water in the form of precipitation and the lost water due to percolation and evapotranspiration. This computation is usually combined with a water balance computation for determining storage requirements. For each treatment system this procedure is somewhat different. Therefore, computations of wetted land area are discussed separately for each process and summarized in Table 6-7. 6-8 TABLE 6-7 SUMMARY OF APPLICATION PERIODS FOR LAND TREATMENT SYSTEMS Unit process Crop management Slow rate Annual crop Double crop or perennials Rapid NA Application Description Growing season only All year unless restricted by weather or planting and harvesting All year-round, if in free infiltration draining materials Overland flow Perennial All year unless restricted grasses by weather Estimated period 3-5 months 6-12 months(also see Figure 6-2) 12 months See Figure 6-2 NA = not applicable. a. This period is maximum in semiarid areas. The lower values should be used where winters are severe. 6.2.4.1 Application Area For Slow Rate Systems The application area for slow rate systems is based on a weekly application rate and the length of the application season. The permeability of the predominant soil types combined with crop water use determine a weekly application rate, as shown in Table 6-8. Water use requirements of most crops will be met using the rates presented in Table 6-8.

Application during growing season. Year-round application Volume applied equally during 5 to 7 days per week; low value for screened effluent and higher rates for primary and biological treatment effluent. 1 in./wk = 2.54 cm/wk 6-9 The length of the application season should be computed on the basis of intended management. Two management techniques are commonly practiced: 1. Grow single, annual crop 2. Grow perennial forage grasses, practice double -cropping, or use the no -till management system For a single annual crop, the application period will be the growing season plus any preplanting or after harvest irrigation and could result in an application period as short as 3 months. For this reason, the second management technique is generally used. For the second case, the application season is determined from climatic data given in a county soil surveyor other local source, for the proposed vegetation. The mean growing season, Le., the number of weeks between the last 32°F (0°C) occurrence in the spring and the first 32°F (0°C) occurrence in the fall, is used for all annual crops. Typical annual crops used in the United States with land treatment systems are corn, wheat, barley, cotton, and soybeans. To extend the application period for annual crops, they may be double -cropped, or winter or spring cover crops may be planted after harvesting. Perennial crops are typically forage grasses such as Bermuda grass, orchard grass, tall fescue, Reed canary grass, and alfalfa. Wastewater can be applied between occurrences of 26°F (-3.3°C) temperatures in the spring and fall. The application period should be reduced by 30 to 45 days to allow for planting (annual crops only) and harvesting periods. The annual application volume is determined by multiplying the weekly rates from Table 6-8 by the length of the application season in weeks. The annual application rate determines the required application area according to the following equation: F = 36.8 0^ LR where F = field area, acres (ha) Q = annual flow, Mgal/yr (m3 /yr) L = period of application wk/yr R = rate of application, in./wk (cm/wk) 36.8 (0.01) = conversion factor = 3.06 acre-ft x 12 in. Mgal ft (6-1) 6-10 6.2.4.2 Application Area For Rapid Infiltration Systems Where application of wastewater to an infiltration basin is by flooding, the period of application is the entire year. An exception may occur under one of the following conditions: 1. The soil is fine textured or not free draining so freezing of water within the soil pores renders it impermeable. 2. The water is applied by sprinkler methods, and the droplets freeze and coat the surface with ice. 3. There is a severe low temperature resulting in freezing of water in the distribution piping or as it exits. Although some provision is recommended for storage to account for one of the above events, the application period can be assumed as 12 months. The application rate can be selected from Table 6-8 based on soil permeability. Then, using Equation 6-1 and an application period of 52 weeks, the application area can be computed. 6.2.4.3 Application Area For Overland Flow Systems This process requires an effluent discharge to either a surface water body or another unit process. Consequently, application rates are not dependent on soil permeability but rather on biological activity. Experience has indicated that an application rate of 4 in./wk (10 cm/wk) will easily match biological activity on the prepared slopes. The application period is usually determined by climatic conditions. These conditions are similar to those for perennial grasses with slow rate systems. in general, Figure 6-2 can be used to esiimate the number of days that overland flow cannot operate. Subtracting this period in weeks from 52 wk/yr will result in the application period. Using Equation 6-1, the wetted area can be computed. 6.2.5 Preapplication Treatment Preapplication treatment is desirable for small scale systems to control nuisance: and odor conditions during storage with slow rate and overland flow systems, and to lessen bed maintenance on rapid infiltration systems. Biological treatment is often employed with many forms of land treatment but may be avoided with overland flow. Also, rapid infiltration may be used with only primary level treatment but the application rate must be reduced somewhat over that of secondary level because of the clogging effect of suspended solids. The use of primary 6-11 FIGURE 6-2 ESTIMATED WASTEWATER STORAGE DAYS BASED ONLY ON CLIMATIC FACTORS [6] SHADING DENOTES REGIONS WHERE THE PRINCIPAL CLIMATIC CONSTRAINT TO APPLICATION OF 1ASTEKATER 15 PROLONGED WEE SPELLS grg n ion S 0 0 ;LrLE MILES BASED ON 32°F (0°C) MEAN TEMPERATURE 0.5 in./0 PRECIPITATION. 1 In.

Typically oxidation ponds or aerated lagoons. 6.2.6 Storage Requirements Storage volume estimates must include consideration of the total water balance for the year. However. the designer can approximate this storage by referring to Figure 6-2 and selecting the proper values for the geographical location in question. The values taken from the figure represent days of storage for the worst year in 20, based on severity of winter conditions. Storage requirements may be further reduced by seasonal discharges to surface waters if permitted by the state. Storage volume guidelines are summarized in Table 6-10. TABLE 6-10 GUIDELINES FOR STORAGE VOLUMES Land treatment process Storage volume guidelines Slow rate Annual crops Perennial crops Rapid infiltration Overland flow Up to 9 months of flow 0.5-6 months of flow, see Figure 6.2 7-30 days of flow See Figure 6-2 6-13 6.2.7 Selection of Application Systems In preliminary design for slow rate, the method of applying the water must be decided. Surface application is preferred where the site topography is quite flat or is suitable for application with a minimum amount of leveling. This method of application offers the least capital cost and the least operation and maintenance cost for most systems. Also, there should be no problems with aerosol transport or need for buffer zones. Sprinkler application may be used for almost any topography, but preferably one having slopes of less than 15% to minimize difficulties with effluent runoff and erosion control. For small systems, the use of surface application systems is preferred for both rapid infiltration and overland flow treatment. 6.2.8 Postapplication Treatment In those cases where effluent is collected for discharge to surface waters, discharge requirements must be met. Systems with overland flow may require postdisinfection. Disinfection may be accomplished using hypochlorinators or, in some cases, an erosion feeder type of chlorinator may be used. The latter units have not been widely accepted but may offer suitable reliability for very small systems. 6.3 Facilities Design As in other parts of this manual, no attempt will be made to discuss the detailed design of preapplication treatment and storage facilities. The discussion is limited to the distribution and application systems. In addition to the comments contained in this chapter, the reader is directed to Section 5.8 for detailed design guidance. -Distribution and application systems will be discussed for each land treatment process in the following section. 6.3.1 Slow Rate System A schematic diagram showing the typical elements of a slow rate system is presented in Figure 6-3. 6.3.1.1 Surface Application Systems Surface application systems require site -specific design, while sprinkler system design should be based on consultation with the 6-14 September 15, 2003 Mr. Cecil L.

Ross, Jr., Secretary Department of Environment and Natural Resources Alan W. Klimek, P.E., Director Division of Water Quality Subject: Additional Information Request NPDES Application for Expansion Newland WWTP - NC0021857 Avery County Dear Mr. Lewis: The Division has completed its first review of the application package submitted on your behalf by Vaughn & Melton. During our review, a number of questions were raised that necessitate additional information. Items requiring attention are detailed below.. 1. Insufficient Flow Justification. The Division recognizes that growth in Newland is likely. However, the justification for flow in the Engineering Alternatives Analysis (EAA) is insufficient. It is evident that the Town has struggled with inflow/infiltration in recent years. In justifying the requested expanded flow of 0.8 MGD, the aforementioned EAA used the maximum monthly flow as a baseline for existing treatment need. It further incorporates 20% above "total future flow" to accommodate for inflow/infiltration (I/I). This appears to constitute double -counting for I/I. The maximum monthly flow of 380,000 gpd undoubtedly includes a substantial quantity of I/I. Based on the I/I determination provided later in the EAA, as much as 250,000 gpd or more of the maximum monthly flow can be attributed to I/I. Inclusion of an additional 20% is inappropriate. The 25% reserve flow offered in the EAA is also not an appropriate figure. The 25% was based on the maximum monthly flow (substantially higher than necessary given the I/I situation). As I'm sure you are aware, the Division does not grant expansion of NPDES permits, and thus wastewater treatment needs, to accommodate excessive I/I. The Town must have its engineering consultant, to the extent possible, accurately quantify existing I/I to determine an appropriate flow for permitting purposes. Additionally, items such as future commercial flow (18% of total) need to be justified. 2. Land -Disposal Alternatives. For the purposes of the EAA, assume a best -case soil loading rate, calculate the necessary land for each non -discharge alternative, and assume that sufficient land is available for purchase. A detailed cost analysis is required for each alternative. Such an analysis should include capital costs for construction of the treatment system (including land acquisition) and a 20-year present value analysis articulating the impact of annual operation and maintenance costs (including labor, analytical, etc.) on the true cost -to -operate each system. 3. Surface Water Discharge Alternative. Costs for the surface water discharge alternative have not been sufficiently itemized in the EAA. The analysis must detail the various component costs to establish, with reasonable accuracy, an estimation of capital costs for construction. While these costs were provided in general in the back of the EAA, they were not referenced and unit costs were not provided for items such as yard piping, etc. Furthermore, a reasonable estimation of electrical load should be determined with an annual electrical cost incorporated into the recurring costs (labor, operation and maintenance, analytical, etc.). All costs must be documented with sources clearly referenced. 1617 MAIL SERVICE CENTER, RALEIGH, NORTH CAROLINA 27699-1617 - TELEPHONE 919-733-5083/FAX 919-733-0719 VISIT US ON THE WEB AT http://h2o.enr.state.nc.us/NPDES Permit No. NC0021857 Town of Newland WWTP Page 2 Please provide the additional information requested herein by July 31, 2003.
