Dear Mr. Chapin Mr. Clement Riddle of Clearwater Environmental Consultants, Inc., on behalf of Mr. Barton Tuck, requests a letter of concurrence from the North Carolina Wildlife Resources Commission (Commission) to obtain a 404 permit from the U.S. Army Corps of Engineers. We reviewed information provided by the applicant and are familiar with habitat values of the project area. These comments are provided in accordance with provisions of the Clean Water Act of 1977 (33 U.S.C. 466 et seq.) and the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d). Mr. Tuck proposes construction of Phase I of the Bright's Creek development (347 lots) and a companion golf course on 981 acres of a 4,400-acre tract in the Bright's Creek watershed. The project would impact 290 linear feet of unnamed tributaries to Bright's Creek. Compensatory mitigation for the impacts includes 300 linear feet of stream restoration from channel relocation and removal of four existing culverts. Restrictive covenants for 25-foot buffers will be implemented on 36,146 linear feet of the total 69,130 linear of unimpacted streams in phase I portion of the tract. The Division of Water Quality classifies Bright's Creek and its tributaries as C trout. Bright's Creek potentially supports trout, but it is not designated by the Commission as trout waters. Further, the lower end of the hatchery supported segment of the Green River occurs at its confluence with Rash Creek, which is a short distance downstream of the project site. The Commission is encouraged that Phase 1 of the development was apparently designed to extensively avoid and minimize direct impacts to streams and that aquatic resources should benefit from the stream restoration. We encourage the applicant to design future phases on this tract similarly. Further, we request the opportunity to review the final mitigation plan that will detail the restoration work. Mailing Address: Division of Inland Fisheries • 1721 Mail Service Center • Raleigh, NC 27699-1721 Telephone: (919) 733-3633 ext.281 • Fax: (919) 715-7643 eni Btight's Creek, 16 2 January 31, 2004 Polk County r The Co tss n is concerned about adverse effects on trout and other aquatic resources in this drainage fromsfkm t mperature elevation and sedimentation that may because of vegetation removal and construction;'particularly that occurring on portions of the development with progressively steeper topography. The buffer preservation should help minimize those effects on approximately one-half of the Phase 1 streams, which are listed in the application as delineated but not field surveyed. We presume that since the protective instrument will be covenants that these streams occur within the subdivision portion of the development. The plats depict buffers along streams in the golf course portion of the development, but it is not indicated how much or what type of vegetation disturbance will be conducted within the buffers for fairway clear zones, golf cart crossings, etc... Also, the mitigation calculations on the plats (page 5 of 23) indicate preservation of upland buffers on 69,130 linear feet, but it is unclear how that preservation will be maintained. We request further clarification on the location of the streams under the protective covenants and other buffer impacts that may be conducted in this development, including those associated with the golf course and any necessary driveway impacts associated with individual lots. We also recommend that where possible the applicant implement the largest undisturbed riparian buffer possible to not only provide important water quality functions, but also to conserve their wildlife habitat functions, which typically improve with size. A minimum 50-foot buffer along intermittent streams and 100 feet along perennial streams is advisable. The applicant should also consider that wildlife conflicts may be problematic in this development, particularly because of proximity to a large population of Canada geese at Lake Adger. We recommend that a wildlife management plan be developed to address these issues proactively. Technical information on wildlife management can be solicited from Mr. Mike Carraway, the Commission's District 9 wildlife biologist, at (828) 646-9913. Although the Commission has concerns with impacts of the proposed project, we can concur with the issuance of the 404 permit provided the previous requests are satisfactorily addressed and the following conditions are placed on the subject permit: I. As indicated by the applicant, work in streams and within the 25-foot buffer is prohibited during the trout spawning period of Oct 15-April 15 to minimize impacts on the egg and fry stages. 2. Stringent sedimentation and erosion control measures must be implemented and maintained on the project site until project completion to avoid impacts to downstream aquatic resources. Temporary or permanent herbaceous vegetation should be planted on all bare soil as soon as possible and within 15 days of ground disturbing activities to provide long-term erosion control. Tall fescue should not be used in riparian areas. We encourage the applicant to utilize onsite vegetation and materials for streambank stabilization when practicable. Erosion control matting should be used in riparian areas, instead of straw mulch. 3. Culverts that are less than 48-inch diameter should have the floor of the barrel installed 20% of the diameter of the culvert below the level of the stream bottom. Culverts that are 48-inch diameter or larger should be placed with the floor of the barrel 12 inches below the stream bottom to allow natural stream bottom materials to become established in the culvert following installation and to provide aquatic life passage during periods of low flow. This may require increasing the size of the culvert to meet flow conveyance requirements. Any perched culverts should be corrected during construction. 4. The natural dimension, pattern, and profile of the stream above and below the culverts should not be modified by widening the stream channel or changing the depth of the stream. 5. Under no circumstances should rock, sand, or other materials be dredged from the wetted stream channel under authorization of this permit, except in the immediate vicinity of the culverts. Instream dredging has catastrophic effects on aquatic life, and disturbance of the natural form of the stream channel will likely cause downstream erosion problems, possibly affecting other landowners. $ Bright's Creek, NW 39 3 January31, 2004 Polk County 6. Excavation of the stream crossings should be conducted in the dry, if possible. Sandbags, cofferdams, flexible pipe, or other diversion structures should be used to minimize excavation in flowing water. 7. If concrete is used during culvert installation (e.g., headwalls), a dry work area should be maintained to prevent direct contact between curing concrete and stream water. Water that inadvertently contacts uncured concrete should not be discharged to surface waters due to the potential for elevated pH. 8. Rock check dams at culvert outlets should be removed at project completion to avoid blocking movement of aquatic life. 9. Stormwater should be directed to buffer areas or retention basins and should not be routed directly into streams. Bridges should not have drains that allow direct discharge of stormwater from the deck to the stream. 10. Riprap should be minimized and installed in a manner so as not to interfere with aquatic life passage during low flow conditions. Riprap placed for bank stabilization should be limited to the streambank below the high water mark, and vegetation should be used for stabilization above the high water elevation. 11. Removal of vegetation and grading and backfilling at the stream crossing and adjacent to streams should be minimized. Native trees and shrubs (e.g., rhododendron, dog hobble, willows, alders, sycamores, dogwoods, black walnut and red maple) should be planted along the streambank to reestablish the riparian zone and to provide long-term erosion control and cover for fish and wildlife in the vicinity of the road crossing and along the streams within the dedicated rights of way. Backfill materials should be obtained from upland sites. 12. Heavy equipment should be operated from the bank rather than in the stream channel whenever possible in order to minimize sedimentation and reduce the likelihood of introducing other pollutants into the stream. All mechanized equipment operated near surface waters should be inspected and maintained regularly to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids or other toxic materials. 13. Discharging hydro -seed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is strictly prohibited. 14. This permit does not authorize the discharge of waste rock and dirt into the streams or riparian zone except for permitted areas associated with culvert extensions and channel changes. 15. As depicted, ponds should have a primary bottom water draw to minimize the potential for temperature increase and associated trout habitat degradation in downstream waters.

The design is in reference to Additional Condition #7 under the original permit modification letter DWQ# 03-1625 dated May 26, 2005. Additional Condition #7 refers to the maintenance facilities and states that "a written stormwater management plan shall be written and implemented before any structure is to be occupied." The goal for this project is to address the maintenance facility water quality design as the stormwater collection systems have been installed along with the parking areas and maintenance sheds. Maps of the project site can be found in Appendix A. Project Approach Since the stormwater collection systems have already been installed, a conservative design approach was implemented. The Golf maintenance shed area consists of 1.4 acres with approximately 70% of that area being impervious due to the buildings and parking areas. The drainage areas were analyzed using SCS methodology. The SCS inputs utilized are found in Table 1. Table 1: SCS Watershed Inputs Landuse Type Area Acres Chl Golf Storage Facility 0.16 98 Sidewalk 0.01 98 Parking Area 0.80 98 Grassed Areas 0.43 69 Total Area 1.40 Area Weighted CN 89 A conservative average time of concentration (TOC) of 0.1 hrs (6 min.) was selected for the entire drainage area. The soils of the drainage area were determined to be of hydrologic soil group (HSG) `B'. Hydrologic soil group `B' is defined as soils having moderate infiltration rates when thoroughly wetted and consist chiefly of moderately deep, moderately well drained soils with moderately fine to moderately course textures. Soils maps of the project site can be found in Appendix B. The SEDCAD4 model was used to simulate runoff for the selected storm frequencies and for evaluating and routing various permanent dry detention designs to adequately meet NCDWQ standards. The SEDCAD4 program output files are included in Appendix B. March 23, 2006 Bright's Creek Golf Course 2 Stormwater and Water Quality Report Permanent Stormwater Quality Management Due to land constraints, previous site development and limited drainage areas, a step pool dry detention pond system with a wooded buffer area was selected to provide permanent stormwater quality management. With a site drainage area of only 1.4 acres, stormwater wetlands and wet detention ponds were not considered. The NC DENR Stormwater Best Management Practices Manual suggests that stormwater wetlands and wet detention basins should have a minimum contributing drainage area of 10-acres (25-acres or more is preferred). Bioetention was not selected because the NC DENR Stormwater Best Management Practices Manual states the bioretention should not be used in areas where mature trees would have to be removed solely to construct the bioretention area. A heavy stand of mature trees and mountain laurel would have to be removed to properly install a bioretention area on this site. The pond was designed to capture the rainfall from a 1-inch storm event which was selected to be a 2-year 0.5 hour storm (1.32 inches) based on NOAA's Atlas 14 data collection chart for the greater Tryon, NC area. The NOAA table can be found in Appendix C. The pond was designed to minimize the extent of impact to the surrounding area with respect to natural habitat and soil grading. The pond utilizes a natural drainage swale that does not require excavation in order to meet the volume requirements. An emergency drain was not installed since the riser structure is adequate to completely drain the pond under the 100-year storm event. The permanent stormwater water quality management system consists of- - A step forebay with a design storage volume of 300 fo (270 ft3 is required based on 20% of the required dry detention volume). - An extended dry detention basin with a design storage volume of 2,400 ft (1,300 $3 required). The peak flow from the pond for the water quality storm event is 1.6 cfs. The design checklist can be found in Appendix D. - A level spreader downstream of the pond outlet to promote ground infiltration and overland sheet flow distribution to the wooded riparian buffer area. The design checklist can be found in Appendix D. - A 300-foot natural wooded riparian buffer area downstream of the level spreader. This entire 300-foot buffer is designated as a "protected riparian buffer" and there will be no construction or disturbance in this area. The buffer area will promote the removal of TSS, nitrogen, phosphorus, and bacteria before flow from the maintenance area reaches Bright's Creek. The wooded buffer will also provide thermal benefits to the runoff from the maintenance area. The IDEAL (Integrated Design and Evaluation Assessment of Loadings) Model was run to calculate the efficiency of the stormwater quality management system. The results of the IDEAL model are shown in Table 2 and the IDEAL design can be found in Appendix G.

A full detail of the detention basin layout can be found in Appendix E and a description of the rock gabion system can be seen in Appendix F. Both the detention basin berm and level spreader will be protected with Erosion Control Blankets (ECBs) and permanently seeded within 14 days of completion of the project in accordance with N.0 seeding specification # 1 M. The seeding specifications can be found in the N.C. Erosion and Sediment Control Planning and Design Manual. March 23, 2006 Bright's Creek Goff Course 4 Stormwater and Water Quality Report MAINTENANCE AGREEMENT Extended Dry Detention Basin and Forebay Extended dry detention basins require frequent mowing and unclogging of outlets. The following maintenance requirements must be followed: • Mow all grassed areas of an extended dry detention basin at least twice annually and repaired with seed or sod to restore dead or damaged ground cover. • Extended dry detention basins collect debris and sediment. Remove sediment when it reduces the pond volume by 25% (top of clean out stake), or at least twice annually. • Inspect the basin annually immediately after a rain event to ensure that it is operating as designed. • Clean out the pond forebay when sediment reaches top of cleanout stake. At a minimum, included and address the following items in the annual inspection: • Clogging of the outlet or too rapid release • Erosion on the banks or replacement of Erosion Control Blankets • Erosion at the inlet and outlet • Sediment accumulation and the need for removal in the basin and the forebay • Condition of embankment due to the emergence of woody vegetation Level Spreader Until permanent vegetation is established, the level spreader should be inspected every seven days and within 24-hours after each rainfall event that produces %-inches or more of precipitation to ensure that it is functioning correctly. The contractor should avoid placement of any material on the structure or prevent construction traffic across the structure. If the spreader is damaged by construction traffic, it should be immediately repaired. Level spreaders require frequent maintenance. The following maintenance requirements shall be performed: • Mow all grassed areas at least twice annually. • Inspect for erosion, rills and gullies annually. Repair damaged areas with seed and permanent Turf Reinforcement Matting (TRM) as needed. • Remove litter and debris annually or as needed. March 23, 2006 Bright's Creek Golf Course 5 Stormwater and Water Quality Report Wooded Riparian Buffer Wooded riparian buffers require maintenance to repair erosion and protect against wildlife damage, insect damage and disease problems. Periodic thinning and harvesting of mature trees may be required to maintain buffer health and growth. At a minimum, the following maintenance requirements must be followed: Inspect and repair erosion, rills, gullies or water channelization (monthly and following each large rainfall event). Inspect trees and shrubs to evaluate their health (every 6-months). Remove of evasive vegetation (every 6-months). Maintenance Facility Spill Containment BMPs The maintenance facility will provide and maintain spill containment BMP's on -site to eliminate spills from entering the storm drainage system. The owner/superintendent will conduct annual training to the maintenance facility staff on the location, application and use of each spill containment BMP. BMPs should be implemented to prevent and control spills in a manner that minimizes or prevents the discharge of spilled material to the storm drainage system. They apply anytime chemicals and/or hazardous substances are stored or used on -site. These substances may include, but are not limited to: • Herbicides; • Pesticides; • Growth inhibitors; • Fertilizers; • Deicing/anti-icing chemicals; • Fuels; • Lubricants; and • Other petroleum distillates. To the extent that the work can be accomplished safely, spills of oil, petroleum products, substances listed above, and sanitary and septic wastes should be contained and cleaned up immediately. If a spill, regardless of size, of a hazardous substance reaches surface waters, DWQ must be notified. When reporting a spill, the following information must be provided: • Reporting party; • Material released; • Concentration or amount of material; • Contact phone number(s); • Resource damages (e.g., dead fish); March 23, 2006 Bright's Creek Golf Course 6 Stormwater and Water Quality Report Location; Responsible party; and Cleanup status. Training Educate employees on what a "significant spill" is for each material they use, and what is the appropriate response for "significant" and "insignificant" spills. Educate employees on the potential dangers to humans and the environment from spills and leaks. Hold regular meetings to discuss and reinforce appropriate disposal procedures. Provide specific cleanup instructions for different products handled on -site. Assign a person to be in charge of cleanup assistance. Prepare spill containment and cleanup lists that are easy to find and use. Post a summary of the cleanup plan at appropriate locations. Cleanup and Storage Procedures If a spill occurs, demobilize it as soon as possible. If there is a chance that the spill could enter a storm drain or sewer, plug the inlet and turn off or divert any incoming water. Cover the spill with the proper absorbent material. Do not use straw. Dispose of the used absorbent per manufacturer's instructions. If the spill is flammable, dispose of as directed by the local fire marshal. Keep the area well ventilated. Minor Spills — Minor spills typically involve small quantities of oil, gasoline, paint, etc., which can be controlled by the first responder at the discovery of the spill. Use absorbent materials on small spills rather than hosing down or burying the spill. Semi -Significant Spills — Semi -significant spills still can be controlled by the first responder along with the aid of other personnel. This response may require the cessation of all other activities. Contain the spill immediately. If the spill occurs on paved or impermeable surfaces, clean up using "dry" methods (absorbent materials, cat litter and/or rags). Contain the spill by encircling with absorbent materials and do not let the spill spread widely. If the spill occurs in dirt areas, immediately contain the spill by constructing an earthen dike. If the spill occurs during rain, to the extent that it doesn't compromise clean up activities, cover spill with tarps or other material to prevent contaminating runoff. March 23, 2006 Bright's Creek Golf Course Stormwater and Water Quality Report Sienificant/Hazardous Spills — For significant or hazardous spills that cannot be controlled by personnel in the immediate vicinity, the services of a spills contractor or a Haz-Mat team should be obtained immediately. Maintenance personnel should not attempt to clean up the spill until the appropriate and qualified staff has arrived at the job site. Spills should not be buried or washed with water. Previously used spill containment materials, contaminated materials, and recovered spill materials that are no longer suitable for the intended purpose should be stored and disposed of properly. Water used for cleaning and decontamination should not be allowed to enter storm drains or watercourses and should be collected and disposed of in the proper manner. Proper storage, clean-up and spill reporting instructions for hazardous materials stored or used on the project site should be posted at all times in an open, conspicuous and accessible location. Waste storage areas should be kept clean, well organized and equipped with ample clean- up supplies as appropriate for the materials being stored. Perimeter controls, containment structures, covers and liners should be repaired or replaced as needed to maintain proper function. Inspection and Maintenance Verify weekly, that spill control clean up materials are located near material storage, unloading and use areas. Update and stock appropriate clean-up materials whenever changes occur in the types of chemicals used or stored onsite.

DATE: 1-12-06 4 Tj DWG # PROJECT # APPENDIX F TERRA AQUA GABION INFORMATION AND INSTALLATION SPECIFICATIONS March 21, 2006 Bright's Creek Golf Course F Stormwater and Water Quality Report TERRA AQUA GALVANIZED GABION Scope: This specification data sheet covers the use of galvanized steel double twisted woven wire mesh gabion baskets filled with stone and used for various applications including but not limited to retaining walls, mechanically stabilized soil retaining structures, stream bank protection, slope paving, outfall structures, weirs, drop structures, etc... Definition: a) Gabions are defined as double twisted woven wire mesh box shaped baskets, of various sizes and dimensions. b) The selvedges of the gabion baskets are the thicker perimeter and edge wires to which the wire mesh is secured as to withstand sudden or gradual stress from any direction. c) Reinforcing wires are the thicker wires incorporated into the netting during fabrication. d) The internal diaphragms are the internal wire mesh partitions which divide the gabions into cells. e) Lacing or tie wire is used to assemble and join the gabion units. f) Connecting wires are the internal wire used to prevent the gabions from bulging. g) Alternative wire fasteners are ASTM approved wire fasteners used in lieu of lacing wire. Fabrication: Double Twisted Hexagonal steel wire mesh Galvanized Gabions. Gabions shall be fabricated in such a manner that the sides, ends, lid and diaphragms can be assembled at the construction site into rectangular baskets of the sizes specified and shown in the drawings. Gabions shall be of single unit construction: the base, lid, ends, and sides shall be either woven into a single unit or edge of these members connected to the base section of the gabion in such a manner that strength an flexibility at the connecting point does not compromise the engineered structural design of the gabion. Where the length of the gabion exceeds on an one half its horizontal width, the gabion shall be divided by diaphragms of the same mesh and gauge as the body of the gabion, into cells `whose length does not exceed the horizontal width. The gabion shall be furnished with the necessary diaphragms secured in proper position on the base in such a manner that no additional tying is required at this juncture. Mesh Formation: The double twisted hexagonal wire mesh shall have deformability sufficient to permit minimum of mesh elongation equivalent to 10% of the unstretched length of the mesh test section without reducing the gauge or the tensile strength of the individual wire strands to values less than those for similar wire, one gauge smaller in diameter. Non -Raveling: The double twisted hexagonal wire mesh is to be fabricated in such a manner as to be . non raveling. This is defined as the ability to resist pulling apart at any of the twists or connections forming the mesh when a single wire strand in a section of mesh is cut or broken. Gabion fill: The stone fill material used for filling the gabion units shall be clean, hard stone with pieces ranging from 4 — 8 inches on the greatest dimensions. Stone filling shall not exceed 24 inch vertical drop above the gabion basket. All effort shall be made to ensure that the stone fill material utilized in the design of the structure match the stone fill used in constructing the gabion structure. Assembling and placing:. a) Each gabion unit shall be assembled by tying or fastening all connecting seams. The binding wire shall be tightly looped around every other mesh opening along the seams in such a manner that single and double loops are alternated. An alternative wire fasteners may be used in lieu of lacing wire. The alternative wire fasteners shall be applied at approximately 4" - 6" intervals on all vertical and horizontal seams. No less than 3 fasteners per one foot on any given seam. b) A line of empty gabions, shall.be placed into position according to the contract drawings. Binding wire or alternative wire fasteners shall be used to secure each unit to the adjoining one along the vertical reinforced edges and the top selvedges. An approved corner closure tool shall be used to adjoin adjacent gabions to insure a' tight, neat seam and minimize gabion wired or fastened to the latter at front and back. The lid shall be secured with an approved closure tool to insure proper closure without excessive mesh deformation. c) To achieve optimum alignment and finish for retaining walls, a minimum amount of stretching may be required. d) Connecting wire shall be inserted during the filling operation as follows: The connecting wires shall be installed according to manufacturers instructions every 1' vertical lift of the gabion unit.

Salisbury St. Raleigh NC 27604 RE: . Bright's Creek Phase One Low Pressure Sewer System LDI Project No. 6003050 Permit # WQ 0024460 Dear Mr. Ascenzo, Enclosed please find one (1 )sets of as built record drawings and a partial certification for the Bright's Creek Phase 1 Low Pressure Sewer system located in Polk County, North Carolina. The plans were permitted and approved under Permit # WQ 0024460 by Marie Doklovic, P.E February22 2005. This partial certification is for the Phase 1 Sewer System including the collection system the intermediate pump station and force main to the waste water treatment plant. This certification does not include the sewer collection system that serves Lots 296 thru 303 on Green Road. This portion of the system will be included in the final certification upon completion of construction and testing. A number of minor adjustments to the originally submitted plans have been made due to field constraints and preferences of the owner/operator Heater Utilities. These changes are summarized below. None of the field changes result in a non compliance situation. Field Changes 1. The final pump used at the intermediate pump station was an ABS pump AFP 1048 instead of the originally permitted Flygt pump. This change was due to a preference by the operator of the system and there familiarity with maintaining ABS pumps. This revised pump still hits the required operating point on the system .curve. 2. The layout of the intermediate pump station site is slightly different, than that shown in the permitted plans with the wet well being located furthest from the road and the gas generator moving closer to the road. 3. The below ground backflow preventer assembly vault at the intermediate pump station was replaced with an above ground "Hotbox" unit. If you should have any questions, comments or need any additional information during your review please call. We appreciate your efforts to expedite permitting of these plans.

L INTRODUCTION BACKGROUND The parcel of land under consideration for the installation of the low-pressure sewer system is the proposed Bright's Creek Golf Club and Subdivision. Bright's Creek is a golf -course community located in Polk County. The overall project is 4,354 acres and consists of several phases. Access to the site is via Palmer Road State Route #1155 (see attached map). The site has a variety of natural features and terrain ranging from steeply wooded areas to rolling meadows and orchards all accessible by existing logging roads which traverse throughout the site. The site contains various creeks and tributaries that serve as the headwaters of the Bright's Creek watershed. SCOPE The purpose of this section is to provide detailed design calculations to support sizing of pumps for the 303 residential lots and associated golf course infrastructure in Phase One and establish design flows for each pressure main segment (zone). It is proposed to design and construct all of the low-pressure facilities and intermediate pump station to collect the waste water and transport it to the on -site waste water treatment plant. DESCRIPTION OF PRESSURE SEWER SYSTEM The following represents requirements for the pressure sewer systems proposed for the Bright's Creek Subdivision and Bright's Creek Golf Course. Each individual residential lot, the real estate sales center, golf maintenance office and the swim and tennis facility will be served by pressure sewer and identical simplex pump stations Gatorgrinder/AMGP by eOne. The pumps will be located in a prefabricated 658 gallon fiberglass pump vault located outside of the 100 year flood zone. 2. Responsibility for ownership, operation and maintenance of the grinder pump, basin, control panel, and the discharge main from the unit to the street right-of-way will be by Heater Utilities, Inc., who will own and operate the system. 3. Heater Utilities, Inc. will have a repair and maintenance contract with a local licensed plumber on call 24 hours a day, seven days a week. The 24 hour call number for service and repair will be clearly posted on all pump stations control panels. All home owners will also be given a booklet outlining the system and what to do in the event that the alarm sounds. G:\6003050\Docs\Sewer SpecsUntroduction.doc - 1 - 6003050 4. Response time to replace a failed pump is estimated to be as follows: Home Owner calls number on control panel Contractor assemble and preparation time = 45 minutes Drive time to site = 30 minutes Pick up pump at wastewater treatment facility and change out at call location = 45 minutes Total response time for pump replacement = 2 hours The maintenance facility is required to have a back up supply of pumps equal to 10% of the installed units. A total of 30 spare Gatorgrinder pumps will be required to be on hand at the final build out of phase 1. The pumps are also available within 24 hours from the manufacturer. 5. Each residential pump basin will provide 476 gallons of emergency storage above the "pump on" elevation with 6" of freeboard. (Single family residences generate 360 gpd), the wastewater flow during a 2 hour response time is estimated to be 52 gallons. The power provider, Rutherford EMC, has provided their most current annual outage and reliability report for the 5 year period, 1997-2001, which indicates an average annual outage of 1.5 hours per customer per year. (See Appendix) 6. The design of the pressure sewer system is accompanied by detail design calculations supporting sizing of pumps and mains providing number of lots and design flow for each segment of pipe; 7. Pressure sewer plans in form and content conform to NCDENR requirements. Plans have been prepared as 1"=200' plan sheets, and separate profile sheets at scales of horizontal 1 "=100' and vertical 1 "=10'. 8. The. pressure sewer system layout for Bright's Creek is shown on the plans depicting: clean -outs for flushing, valves for isolating line segments, air/vacuum release valves, individual cut-off valves at the street right-of- way for each service lateral, and other construction details as necessary. Pipe material is HDPE DR11 and all mains are minimum bury of three (3) feet; 9. The location of all pressure sewer mains will be uniformly two (2) feet off the edge of pavement within a 6' roadway shoulder as applicable to facilitate ease of location for maintenance. The water main will be installed in the opposite roadway shoulder. All pressure sewer mains will be installed with green plastic locator tape to differentiate the pressure sewer mains from water mains. The tape shall be Type III Detectable marking tape by Lineguard, Inc. 10. All low pressure sewer mains outside of the road right-of-way shall have a 20' easement. All residential lots shall have a 10' utility easement along the side property lines. Heater Utilities will also have an access easement to gain access for service and maintenance of the pump stations and alarm panels. GA6003050\Docs\Sewer SpecsUntroduction.doc -2- 6003050 11. The Sales Center will be served by a simplex pump station identical to those used at the residential lots. The daily flow of 300gpd will be less than that generated by a single family residence (360gpd). In the event of a power outage at this office, the sales center would be closed. 12. The swim and tennis center will be served by a simplex pump identical to those used at the residential lots but with the 6' diameter 108" high basin. The daily flow of 1500gpd equates to a peak flow of 3.9gpm (1 500gpm/1 6hrs/60mins x 2.5 peaking factor = 3.9gpm). The gatorgrinder simplex pump can discharge at a rate of 13gpm so will be very capable of handling the maximum flow condition. In the event of a power outage at this facility, the center would be closed. However, we will still be providing the required 24hour emergency storage (1500 gallons) above the pump on elevation. 13. The clubhouse will be served by a triplex gatorgrinder pump station and will have back up power provided by a portable dedicated generator. The wet well will also have 1071 gallons of storage above the lead/lag pump on elevation. Clubhouse Phase 1 = 7500gpd Avg. flow = 7.81 gpm (7500gal/16hrs/60mins) Emergency storage above pump on=1071gal The dedicated standby generator will be a Tsurumi TPG-7000 DXE .The clubhouse will be operating on a very limited service during a power outage and therefore it would not be necessary to run two pumps from this generator to handle a peak flow. 14. The Golf maintenance office will be served by a simplex pump station identical to those used at the residential lots. The office will include a shower, kitchen and restroom facilities for the groundskeepers. The daily flow of will not exceed the that as generated by a single family residence (360gpd). 15. There will be two restrooms on the golf course, each will be served by a simplex pump station. 16. A number of of lines which will be installed within Phase 1 of the Brights Creek subdivision will be also carry sewer flows from future phases. Since the pressure sewer is designed to carry these future flows a number of lines may experience velocities below 2ft/sec when carrying only phase 1 flow. These lines will be designated as high priority lines. And will be inspected and flushed if required at least every 6 months. Flushing connections have been installed on these high priority lines and on the high side of sections of pipe which run at a gradual slope or have high points. G:\6003050\Docs\Sewer Specs\Introduction.doc - 3 - 6003050 These specifications are submitted as minimum criteria to establish a uniform standard of pressure sewer design. The standards are not intended to restrict the addition of other requirements appropriate to insure the high quality of design and construction typical of the said System. D. DESIGN PROCESS The first step in designing a low pressure system is to make a layout of the project. A main line should be established. This is usually a continuous line starting from the discharge point to the furthest point in the system. The next step is to establish the branch lines, sub -branch lines, and junction points. Once the layout and notation are complete, the next step is to complete the r� computer data sheet. Note the information that is required for the upstream station of junction point (laterals and nodes), elevation of junction points, critical elevation (elevation of the grinder pump elevation and highpoints along the route), and pipe diameter. Once the data in the computer worksheets is complete and loaded into the program, the design peak and simulated conditions can be run. Simulated conditions estimate the expected number of pumps on at any one time (operating simultaneously) and expected peak flow rates. From the computer worksheet disk there is detailed information on the system. The velocity in each line segment is shown. Any of the parameters can be modified such as the C factor, pipe diameter, etc. Pipe size may have to be altered to maintain a balance between total head and velocity. Velocity is very important to carry the solids and also prevent the build-up of deposits. High velocities also help to remove entrapped air. E. CONCLUSION / SUMMARY The design of the low-pressure sewer system was designed to accommodate low flows and high heads typical of the Bright's Creek community: The selection of the Environment One Gatorgrinder pump allows for the identical pump to be. used throughout the project for ease of maintenance. The addition of pump basins at each residence allows for the economical collection and treatment of waste in areas of challenging topography. Homeowners at Bright's Creek will be educated as to the maintenance operations of the low-pressure sewer system and how to flush the system prior to leaving for extended periods. The data and computer reports generated demonstrate that the low pressure sewer system operates satisfactorily under a variety of combinations. The velocity present in all the zone lines is adequate under worst case conditions. The system should work well.

INC. 1 Patent Number(s): 5,439,180 Printed in USA, on recycled paper LM000171 Rev. B 5/01 r� u riff-4., General Applications The Gatorgrinder reduces all forms of sanitary waste to a non -clogging slurry and pumps it through a network of small -diameter pipes. Since gravity is replaced by the power of the pump, sewer systems need not run downhill nor require large -diameter pipes, deep trenches, multiple lift stations — or their associated costs. Designed specifically for operation in warmer climates, the Gatorgrinder is an efficient, economic station for single dwelling service. Features The Gatorgrinder is a complete unit that includes: the grinder pump, check valve, fiberglass tank and controls. The fiberglass tank is supplied complete with discharge fitting installed, simplifying installation of the grinder pump and plumbing. All solids are ground into fine particles, allowing them to pass easily through the pump, check valve and small diameter pipelines. Even objects that are not normally disposed of through sewer lines, such as plastic, rubber, fiber, and wood, are ground into fine particles by the Gatorgrinder. The 1-1/4" discharge fitting is adaptable to any piping material, thereby allowing us to meet your local code requirements. The.48"diameter tank is constructed of laminated fiberglass and is available in several depths to accommodate capacity and site requirements. Other tank sizes are available upon request. The integral grinder pump check valve assembly is custom designed for non - clog, trouble -free operation. f 4 TM c, -er Automatic grinder pump activation is provided by the Gatorgrinder level control system. The Gatorgrinder is designed to run infrequently, for very short periods of time. The annual energy consumption is typically that of a 40-watt light bulb. Operational Information Motor 1 HP, 1,725 RPM, high torque, capacitor start, thermally protected, 120/240V, 60 Hz, single phase. Inlet Connection 4" inlet grommet standard for DWV pipe. Field penetration and installation of inlet grommet allows site plumbing flexibility. Discharge Connections Tank is equipped with a factory installed discharge fitting. Tank discharge terminates in a 1-1/4" female NPT thread. Field connection of pump discharge to tank bulkhead is easily accomplished using the supplied discharge assembly or other material required by local code. Discharge* 15 gpm at 0 pig 11 gpm at 40 psig 9 gpm at 60 psig Overload Capacity The maximum pressure generated by the pump is limited by the motor characteristics and overload protection. The motor/pump combination generates a pressure well below the rating of the pipe and appurtenances. The automatic reset feature of the motor does not require manual operation following overload. 'Discharge data includes minimal losses through the check valve.

Proper installation of this equipment will ensure years of trouble -free service. The Gatorgrinder station consists of a grinder pump, tank and pump control panel. The tank is a fiberglass basin complete with a gasket -sealed, fiberglass lid. Sewage enters the Gatorgrinder tank through the 4" (standard) inlet pipe where it is ground into fine particles by the grinder pump. The in -line pumping mechanism discharges the ground sewage to a force main, gravity main or a remote treatment site. The pump is a semi -positive displacement type capable of developing discharge pressures up to 60 psig. Ample tank storage capacity in conjunction with integral level sensing controls provides for economic, on - demand, operation of the grinder pump. ITEMS REQUIRED FOR INSTALLATION Prior to beginning installation of the Gatorgrinder station, a thorough review of these installation instructions is recommended. This will likely eliminate problems with inconvenient piping and cable locations or due to unavailable materials or equipment. In addition to the components furnished with each Gatorgrinder station, the following items will be needed to support installation: • Supply voltage in accordance with the voltage specified on the Gatorgrinder nameplate. • Bedding material (see Section 2) • Concrete ballast (see Section 3) • 4" inlet pipe (from residence or building sewer; see Section 4) • 1-1/4" discharge pipe to force or gravity main; see Section 5) • Compactable backfill material (see Section 8) The following tools: • 5" diameter hole saw • 1-1/16" diameter hole saw ' • Pipe thread sealant (suitable for PVC) • Pipe wrenches • Water pump pliers 1 Electric drill, 1/2" chuck • Common hand tools The following instructions will provide the necessary information to properly install the Gatorgrinder system. All applicable OSHA procedures must be followed during installation of this equipment. k i ' 1. Station Unpacking (Figure 1) The Gatorgrinder control panel, grinder pump and tank are shipped to the job site separately. Inspect the tank (1) and ensure that it sustained no damage'during shipment. Proper handling of the fiberglass tank will ensure reliable performance. Do not drop the fiberglass tank or roll it on its side. Only a non -marring sling ' should be used to lift the fiberglass tank. Ensure that all lifting equipment is rated for the load being lifted. Verify that the discharge fitting (4) is installed on the tank. Remove the fiberglass tank lid (2) and verify that the EQD bracket'(5) and ' lid gasket(3) are installed. The balance of the factory provided components were delivered with the grinder pump unit. Inspect the shipping cartons for signs of any damage sustained during shipment. If damage is suspected on any of the Gatorgrinder components, do not proceed with installation. Notify a Gatorgrinder representative of any damage discovered. Open the shipping cartons and verify that the grinder pump (6), pump stand (7), discharge piping kit (8), supply cable (9), cable grip (10), inlet grommet (11) and control panel (12) are enclosed. Notify a Gatorgrinder representative of any missing components. 2. Site Excavation Excavate a hole of sufficient depth and width to accommodate the tank, underground piping and required backfill material as well as providing adequate working space for plumbing and electrical connections. The base of the excavated hole should be level and prepared with proper bedding material, such as gravel, in accordance with the site Engineer's requirements. The depth of the excavation must be sufficient to accommodate the bedding material and tank burial to approximately 1" below the upper flange surface. The size, shape and shoring requirements of the excavation will be based on the soil conditions and should be in accordance with the site Engineer's recommendation and safety requirements. 3. Tank Installation (Figure 2) Improper handling of the fiberglass tank may result in damage and, ultimately, failure of the station. Care should be taken during lifting and placement to prevent impacting or otherwise damaging the tank. A non -marring sling should be used when lifting the tank by the fiberglass surfaces. Ensure that lifting sling is rated for the load being lifted. Lifting chains or cables should never be placed in direct contact with the fiberglass tank surfaces. Place the tank on the level bed of fill material in the excavated hole. Orient the installed discharge fitting, as required; to align it with the existing or proposed discharge piping path. Determine and mark the 4" DWV inlet pipe location on the fiberglass tank wall. The inlet pipe location corresponds with the actual or projected point where the 4" building sewer line intersects the tank wall. The center of the inlet pipe must be a minimum of 30 inches from bottom of the tank. The slope of the inlet pipe (per national and local code requirements) must be accounted for when ; determining the inlet location. The supply cable path and cord grip location ' should be considered when selecting the inlet location (see Section 7 and Figure 4). If the site conditions require concrete tank ballast to prevent flotation, ensure that the volume of concrete used complies with the site Engineer's recommendation. Concrete ballast, if required, should be cast in place around the tank in the excavation. Do not pour the concrete ballast above the marked inlet pipe location. If the ballast must be poured above this level, proceed with installation of the inlet piping (Section 4) before pouring the concrete. The inlet pipe must be sleeved with an 8" tube prior to pouring. The tank should be filled with water, to a level above the specified ballast height to prevent shifting during the concrete pour. Alternatively, precast concrete, around the tank bottom, may be used for ballast (Figure 2). Do not pour ballast above the intended inlet location. If this ballast method is used, lifting hooks must be anchored in the concrete to support subsequent handling of the tank. The lifting hooks must be adequate to support the combined weight of the tank and concrete ballast, and should be sized and installed in accordance with the site Engineer's recommendation. Place the ballasted tank in the excavated hole using the lifting hooks. Do not lift the tank by any of the fiberglass surfaces if precast ballast is utilized. 4. Vent Installation The Gatorgrinder station is supplied with a 2 mushroom vent, to be installed. in the station cover. Locate the 3" hole in the station cover. A vent'hole may be added to a station cover in the field using a 3" diameter hole saw. Consult the factory before installing a vent hole in an existing station cover. Install the rubber grommet in the hole in the station. The flange on the grommet should sit flush with the station cover. Apply soap to the end of the nipple on the vent assembly. Align the nipple on the vent assembly with the grommet in the station cover and press the vent assembly down into the grommet until the vent housing bottoms on the grommet. 5. Inlet Installation (Figure 3) The type, size and venting requirements of the inlet pipe must be in accordance with all national and local plumbing codes. The Gatorgrinder is a sewage handling pump,and requires ventilation for proper and safe operation. The Gatorgrinder is supplied with a standard grommet to accept a 4" DWV (4.5" outside diameter) sewer inlet pipe. The grommet is self-sealing and does not require the use of additional sealant or adhesives. Other grommet sizes :are available upon request. Verify that the grommet supplied with the Gatorgrinder will accommodate the selected inlet piping. Using a 5" hole saw, drill through the 'fiberglass tank wall at the marked inlet location. Install the supplied inlet grommet in the 5" hole. Place a mark on the inlet pipe 3-1/2" in from the end that will enter the fiberglass tank. A bevel should be ground or filed on the pipe end to aid in installation through the grommet. Clean the grommet and pipe surfaces to remove any debris. Apply a film of pipe soap or dish soap to the outside surface of the inlet pipe end and the inside of the grommet. Insert the pipe end into the grommet and. push the inlet pipe into the fiberglass tank until the 3-1/2" mark lines up with the grommet outside edge. Inspect the grommet flange on the outside of the tank. The flange should be flush against the tank wall and completely visible when the pipe and grommet are installed properly. 6. Tank Discharge Piping Connection Connect the tank discharge piping to the threaded tank fitting. The 1-1/4" NPT �- female thread on the discharge fitting will accommodate a variety of pipe materials and fittings. The discharge fitting is made of reinforced Nylon and the threads may be damaged if over tightened. Use a suitable threaded adapter and thread sealant to connect the discharge piping to the tank fitting. Typically, %2 to 1-1/2 turns beyond hand tight will produce a leak proof seal. Discharge piping must be selected in accordance with local and national plumbing codes. If allowable, the use of 1-1/4, schedule 40, Type 1, PVC pipe or SDR 11 polyethylene pipe is recommended. If polyethylene discharge piping is used, compression type fittings that provide a smooth inner passage should be utilized. 7.-Control Panel Mounting Before proceeding; verify that the supply voltage is the same as the motor �- voltage shown on the grinder pump nameplate. Determine the location of the Gatorgrinder control panel. The control panel may be mounted on a pole or directly on an outdoor wall surface. The mounting location selected must be I visible from the Gatorgrinder station location and provide general visibility to the occupants of the building. To mount the control panel, remove the panel, front 9 P _ cover and secure to `the wall or pole using standard #10 or #12 screws through the two mounting holes located on the back panel. 8. Supply Cable Installation (Figures 4 & 5) A 32 supply cable and cord grip are provided with the Gatorgrinder station for electrical connection between the station and the control panel. All electrical wiring must be in accordance with local codes. The supply cable is rated under the National Electric Code (NEC) for direct burial as long as a minimum of 24" of ground cover is maintained. Those portions of the cable with less than 24" of cover must be housed in a suitable protective conduit. The supply cable; terminates in a convenient, electrical quick -disconnect .(EQD) plug to support future servicing of the grinder pump. The supply cable cord grip provides a leak r tight seal around the power cable as it enters the tank and will prevent movement of the supply cable during burial and subsequent ground settlement. The cord i grip should be installed in a position on the tank that will provide convenient, direct routing of the supply cable to the control panel. The supply cable cord grip should be installed 25" below the top of the tank and within approximately 6" of either side of the EQD mounting bracket (Figure 4). (Exception: On 48" tall tanks the cord grip should penetrate the tank 18" below the top of the tank; the portion of the cable with less then 24" of soil cover shall be installed in suitable protective conduit.) Locate and mark the location of the cord grip on the fiberglass tank wall. Using a 1-1/16" hole saw, drill through the tank wall at this location. Install the cord grip and O-rin.g seal as shown. Tighten the cord grip locknut until snug. Loosen the cord nut and slide the supply cable free end through the cord grip as shown in Figure 4. Continue to slide the entire cable length through the cord grip until the metal cable stop rests against the cord grip face. Tighten the cord nut until snug. Failure to tighten the cord nut will result in groundwater entering the station. Rest the EQD plug end in the holding bracket as shown in Fig. 4. Use care when installing and burying the supply cable. If the cable is cut or otherwise damaged it may result in a' pump malfunction. Run the supply cable underground, ensuring 24", minimum, of soil coverage, to the control panel location. Leave a 6"-12" loop of supply cable near the station and the control panel to accommodate settlement of the soil. A protective conduit must be utilized where 24" of soil cover cannot be maintained (Figure 5). 9. Tank Backfill Proper backfill is essential to the long-term reliability of the Gatorgrinder station. The choice of backfill material is dependent upon the local soil and groundwater conditions and must be in accordance with the site Engineer's recommendation. Heavy non-compactable clays and silts are not acceptable backfill for the G.atorgrinder tank or any other underground structure such as the inlet or discharge piping. Backfill should be placed and compacted in 12" lifts. Special care should be taken when placing backfill around inlet and discharge piping to ensure support and compaction. Do not strike the inlet pipe, discharge pipe or electrical connection with the compaction equipment during backfill. The finished grade should be 1" below the upper flange on the fiberglass tank. The finished grade should be sloped down from the station to prevent water from pooling around the tank. 10. Grinder Pump Stand Assembly (Figure 6) Detach the three stand retaining rings from the pump stand. Temporarily rest the grinder pump on its side. Using a block of wood or similar object, prop up the lower pump end to allow installation of the pump stand. Align the three legs of the pump stand with the three holes in the pump lower end. Push the stand legs into the pump lower end until the bend in each stand leg bottoms against the pump - housing surface. Turn the pump upright on the installed stand. Install one stand retaining ring on each of the three leg ends protruding through the pump lower end. The retaining rings are a pressure fit and are easily tapped in place using a 5/16" socket or nut driver and mallet. The retaining rings should only be driven 1 ' onto each leg approximately 1/4". Do not attempt to bottom the rings against the angled pump surface as this may distort the ring and lessen its holding power. 11. Grinder Pump Installation ' Prior to installing the grinder pump in the tank, flush the inlet pipe with water to force any miscellaneous debris in the sewer line into the tank. Heavy debris such as sand, clay, etc. should be removed from the tank before installing the grinder pump. The Gatorgrinder was supplied with all of the necessary plumbing components to ' connect the pump discharge to the tank discharge. Refer to the separate Gatorgrinder Discharge Plumbing Installation Instructions for the specific discharge arrangement included with this unit. After completing the plumbing connections per the Gatorgrinder Discharge Plumbing Installation Instructions Discharge, proceed with connecting the pump power cable. The grinder pump power cable is supplied with the mating half of ' the EQD connector. Verify that the EQD gasket is in place on the grinder pump power cord (Figure 8)..Plug the pump power cable into the supply cable' EQD connector. Note that the EQD halves are "keyed" and the plug connections can only be made one way. Align the clamping screws on the pump power cord EQD with the threaded holes on the EQD bracket. Secure the EQD connection by tightening the two clamping screws until the EQD plastic "stops" are in contact with each other. Remove the plug from the Equalizer tube installed in the breather port and insert barbed fitting on the Equalizer. (Figure 8) 12. Electrical Connections The Gatorgrinder control panel contains a circuit breaker pair to protect the pump motor and a separate circuit breaker to control the alarm circuit. The station ' supply cable and power supply cable (from the building service) must be run into the panel and appropriately connected. All panel wiring should be completed by a qualified electrician and be in compliance with national and local electrical codes. ' Conduit should be provided, where required by code, and adequate strain relief used on cable and/or conduit entry points. The appropriate wiring connections for the Gatorgrinder are shown in Figure 9. 13. Start -Up Test Procedure When the system is completely installed, the station should be checkedto ensure proper installation and reliable performance. i i 1 1 L SYSTEM INSPECTION Perform the following visual inspections: • Proper burial depth - the tank should have been buried to a level 1" below the fiberglass cover flange. • Proper grading - the surrounding soil should be graded down, away from the station. • Station supply cable - the station supply cable must not be exposed outside of the station. Suitable conduit must be used where proper burial depth (24") cannot be maintained. • Control panel - ensure that the control panel is properly mounted and free of any damage. Verify that the control panel has been wired properly in accordance with the wiring instructions in this manual. ELECTRICAL TESTS The following electrical tests are recommended prior to operating the grinder pump station. These tests require the use of appropriate electrical test equipment and should only be performed by qualified personnel trained in the safe operation of this equipment and electrical system servicing. 1. Ensure that the electrical power supplying the control panel is "OFF". 2. Ensure that the grinder pump (double) and alarm (single) circuit breakers in the control panel are in the "OFF" position. 3. Using a test (ohm) meter, set at a 2 meg ohm setting, measure the resistance between the colored wire pairs shown in Table 1. Resistance readings are to be taken in the control panel on the colored leads supplying the pump station (supply cable). Resistance readings other than those shown in Table 1 may indicate a problem with either the supply cable or the grinder pump. If the measured readings are not as indicated in Table 1, do not proceed with station start-up; contact you local Gatorgrinder or qualified service representative. TABLE 1 COLOR I COLOR 2 NORMAL READING GREEN BLACK GREEN RED GREEN WHITE (: = Infinity or open circuit) 4. Turn "ON" the power to the control panel from the building service panel. 5. Using a test (volt) meter, verify that the incoming panel voltage is within 10% of the pump nameplate voltage (for 240V pump, voltage at panel must be 216V to 264V). If the voltage is outside of this range, do not continue with station start- up. The voltage problem must be corrected prior to proceeding. START-UP TEST The following test must be performed prior to placing the system in service: 1. Ensure all service and control panel breakers are in the "OFF" position. 2. Open the discharge ball valve at the tank discharge fitting. 3. Open any additional discharge lines. Some installations may have additional discharge line valves before entering the street main. 4. Turn "ON" power to the control panel, from the building service panel. 5. Set the alarm circuit breaker in the control panel to the "ON" position. 6. Fill the fiberglass tank with water until the red alarm light on the control panel is lit. 7. Set the grinder pump circuit breaker in the control panel to the "ON" position. Once power is turned on to the grinder pump: o The grinder pump should start immediately. o The red alarm lamp should switch off in approximately one minute. o The pump should stop within approximately three minutes. OPERATIONAL ELECTRICAL TEST The following electrical test is recommended in conjunction with the Start -Up Test of the grinder pump station. This test requires the use of appropriate electrical test equipment and should only be performed by qualified personnel trained in the safe operation of this equipment and electrical system servicing. 1. The current to the grinder pump should be measured in the control panel, at the white wire supplying the pump station (supply cable). 2. Using an ammeter, measure the current in the white wire while the pump is operating. 3. The current should be between 5 amps and 8 amps. 4. Higher amperage indicates higher discharge pressure. Measured current in excess of 8 amps could indicate,a blocked or closed discharge line. Correct any blockage problems and•confirm that the current is within the acceptable range. If the current remains outside of the acceptable range, and no discharge blockage is detected, contact your local Gatorgrinder or qualified service representative. If the grinder pump fails to perform as indicated, review the start-up procedure again and verify that all wiring connections are correct in accordance with these instructions. If the grinder pump still fails to perform as indicated contact your T local Gatorgrinder or qualified service representative B.

N L 1 I I 1 fl Model 100 Hardware, Communications and Control Center'Specifications Overview Mission offers a revolutionary, turnkey monitoring and control system to manage remote sites. Initially, some people think of the Model 100 as an advanced wireless autodialer. Mission will show it. is also an automated management system, primarily for pumping stations and the people who maintain them. The Model 100 RTU has 8 digital, 2 analog and 1 electronic key reader inputs, and 3 outputs. It typically installs in two hours or less. The wireless communication is through the ultra -reliable cellular digital control channel to Mission's automat- ed Control Center. The Model 100 works anywhere in the U.S. and dependably performs in remote or hilly areas where regular cellular doesn't. The data is collected at your secure web site that Mission provides. Your infor- mation is displayed on an easy to understand graphic depiction of your water system. Log on and get a real time snapshot of all RTU's with alarms or AC failures detailed in a single glance. Mission's system can also blend with existing radio SCADA systems and send data right to the host HMI computer. Mission's automated Control Center simultaneously generates alarm and status notifications to your personnel via all pagers, e-mail, faxes, voice phone calls or TCP/IP. All alarms are easily confirmed by time arid- recipient. Electronic RTU service keys document and log service person- nel site inspections and maintenance. Mission can supply you with virtually all information needed for CMOM/state EPA reporting for your pump stations; from rainfall/wet weather event documentation, I &'I estimates, pump station performance and maintenance, to alarms and documented responses. General Description For the first time, this industry has available a truly low cost, wireless monitoring and control RTU that will work virtually everywhere you want, and will outperform autodialers and most long range radios. It's extremely easy to use, and it's small enough to fit inside an existing PLC's NEMA enclosure. Messages arrive at Mission Control from field RTU's located anywhere in the country,in 2 seconds or less. Mission then delivers the alarm or status message to your existing phones, pagers, faxes, etc., in addition to storing the event at your custom Mission web site. There are no cellular con- tracts or licenses to obtain. Mission handles all hardware and services. In addition to more standard SCADA functions such as reporting general alarms, pump run times, pump starts, meter reading and well or tank level monitoring, etc., Mission's system has a number of unique abilities. Mission actually analyses pump performance on a daily basis using customized, long term statistical formulas. When Mission detects abnormal pump performance, it automatically notifies you of the trouble. Catch problems before they become cata- strophic failures. Mission has unique alarm notification scheduling, alarm receipt confirmation abilities and extensive event and service personnel tracking. On-line diagnostics provide a multi -point snapshot of each wireless link. This gives you system confidence and helps you proactively make sure your information keeps flowing. The system continuously self tests and automatically generates and delivers management reports. Now supervisors can conveniently oversee what's happening, who's responding and when it happened. And only Mission can bring you this level of performance, reliability, flexibility and convenience at breakthrough prices. All this at half or less than the price of autod!alers and about half the monthly phone line costs! Replacing costly phone lines,can save $300 per site per year.

A NEW SOLUTION FOR AN OLD PROBLEM Sometimes it's the easiest - and least expensive - solution which works the best. Elegantly simple, PEACEMAKER" (brand) scrubbers are compact, good looking, safe to use and easily installed. There is but one moving part -- an exhaust fan. The negative pressure created prevents malodorous air from leaking out of the enclosed area from which air is being drawn into areas which would generate com- plaints. Only one thing can happen -- foul air goes in, clean air comes out. Vessel design is integral to -the per- formance of the system. Air is pulled through dual chambers and diffused in a manner to maximize distribution and contact with treatment media and chemicals. Demand dependent, chlorine dioxide - releasing media in the first chamber is for oxidizing the worst odors. Sustained -released PERSNICKETY® CountervailantTM media in the second chamber is for polishing the rest. The result is safe, extremely effective, broad-spectrum malodor control. Each technology has a critical role to play: The Oxidizing Chemistry The worst malodors are sulfur -based. The main culprit is hydrogen sulfide (H2S). PEACEMAKERTM scrubbers destroy H2S and mercaptans using chlorine dioxide, which is an extremely powerful oxidiz- ing agent. For example, one pound of chlorine dioxide is equivalent in oxidation power to 2.5 pounds of chlorine; 3.8 pounds of potassium permanganate. And, because chlorine dioxide reacts selectively and primarily with only the most offensive odor producing compounds, PEACEMAKERT"' scrubbers will normally provide a much longer service life than competitive products such as activated carbon. Similarly, chlorine dioxide will remain intact longer than chlorine, hypochlorite, peroxide and perman- ganate. Unwanted reactions do not occur. Power is not needlessly spent. Chlorine dioxide remains available and ready on demand, providing > 99 percent removal efficiency on H2S and mercaptans . The Polishing Chemistry Polishing chemistry provides for. the removal of malodors which are largely nitrogen -based, such as ammonia and methylamine. The media has adsorption properties of its own, but is also impregnated with PERSNICKETY® CountervailantTM, a complex and broadly useful technology. Malodor molecules contain one or more chemically reactive groups called osmophores. Polishing reactions with these groups are varied, but are most commonly electrostatic and/or polymeric. 0 per- snick'e•ty, a. (Colloquial -Scottish dialect) 1. showing extremely careful treatment. 2. fussy, fastidious. The worst smelling malodors usually have the strongest electronegative charges, which are readily drawn to the largely electropositive charges of PERSNICKETY® CountervailantTM. It works very much like a magnet. The union either facilitates a chemical reaction or creates a large molecule of very low vapor pressure. Reacted or adsorbed malodor molecules then allow the formation of a homopolymer lattice which surrounds them. Osmophoric activity ceases. Bad smells are gone. There are two PERSNICKETY® CountervailantTM polishing formulas available. One is odorless. The other is slightly more reactive and has a clean, "soapy' smell. SIZING PEACEMAKERTM SCRUBBERS There are a number of standard PEACEMAKERTM models to choose from. When needed, custom designs are provided.. Except for the smallest models, fans are individually tailored to air flow and static pressure requirements. Proper scrubber and fan sizing depends solely upon good information. Ask your PEACEMAKERTM representative for Form 550-A, "Information Required for Sizing PEACEMAK- ERTM Oxidizing Dry Air Scrubbers". It is likely that you have on hand most or all of the information needed. IMPORTANT NOTE: PEACEMAKERTM scrubbers are designed for the effective control of nui- sance odor. They are not intended for dangerous levels of H2S in confined spaces unless specifically designed to do so. A PEEK INSIDE The drawings below are representative. Actual dimensions can be found in the Specification Sheets which are available on each model. Each scrubber is mounted on a skid. Footprints for standard mod- els range from 20" x 28" to 60" x 60". Passive (no fan) versions are available, and are used mainly on air relief valves. Fan Speed Control Clean Ak Exhaust 1 Chan Polishing Oxidizing Condensat eg. of a Fan Chamber Model Economic ... NO CAPITAL COSTS Motor Fan Chamber Intake rfuser 7user nbly Polishing Oxidizing I Mixing ?AN STYLE r Diffuser Fan Speed Control Foul Air Intake it Diffuser Condcnsate Dratn eg. of a Ventilating Model PEACEMAKERTM scrubbers are normally sized to provide a one-year service life. After one year, we send you a new one, you send the old one back, freight collect. This benefits everyone. It insures product performance and dependability. It insures the peace. And you never have to buy a scrubber. If your requirements should change from year-to-year, simply switch to the appropriately sized PEACE- MAKER. No more out -grown and useless capital equipment. 1 Here's how it works. For a very affordable annual fee, you LEASE, or RENT, or agree to EXCHANGE. Ask your PEACEMAKERTM rep for pricing and Agreement details. NO LABOR AND MAINTENANCE COSTS There just isn't anything to do once you've turned on the fan. And there isn't anything that can go wrong unless the fan gives out. It would be rare, but if such a thing happened, Syneco would send you a new fan next -day air at no charge. You would install it in about thirty minutes. There are no dangerous chemicals to buy and handle. No pumps, valves, bells and whistles to worry about. No media change -outs. No expensive disposal problems -- Syneco Systems handles any dis- posal or recycling required. Change -out may take two hours, once a year. ANOTHER IMPORTANT ECONOMIC BENEFIT -- CORROSION CONTROL Corrosion is substantially reduced. H2S accumulates in the head space of a sealed wet well or other enclosed area. It is not unusual to find several hundred ppm H2S which eventually forms sulfuric acid, a highly corrosive compound. When H2S is continuously drawn off and scrubbed, corrosion is commonly reduced by more than ninety percent. A Peaceful Process ... WHO DOES WHAT AND WHEN? Another strong advantage of PEACEMAKERTM scrubbers is the speed and ease with which you go from problem to solution. Below is a typical example of the time -line and process from start to finish. TASK TIME 1) You provide Syneco Systems with a completed Form No. 550-A, 7 days "Information Required for Sizing PEACEMAKERTM Scrubbers." We can help and advise. 2) Syneco will size a scrubber and submit a quote. 2 days 3) You decide. If it's a go, sign and return the Agreement. 7 days 4) Syneco manufactures and ships your scrubber. 28 days 5) You install it. < 1 day START TO FINISH 45 days Of course, if there is a custom design or bid process, the time -line will be extended. On the other hand, some models are inventoried, and the process may take only two weeks. In any case, the soon- er we start the sooner peace will descend.

All construction activities, including the design, installation, operation, and maintenance of sediment and erosion control Best Management Practices, shall be performed so that no violations of state water quality standards, statutes, or rules occur. 4. Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum extent practicable. If ` placement of sediment and erosion control devices in wetlands and waters is unavoidable, they shall be removed and the natural grade restored within six months of the date that the Division of Land Resources has released the project; 5. Restrictive covenants prohibiting any direct discharge of collected stormwater (such as stormwater collected from roof gutters) to surface Waters of the State shall be placed on all residential properties within the Bright's Creek development; - 6. All stormwater from tees greens and fairways shall be directed to the permanent stormwater management facilities as described in the application. The stormwater management facilities and in -stream plunge pools proposed in the application shall be designed to protect water quality by controlling dissolved pollutants, temperature and discharge. The stormwater management plan shall include an operation and maintenance agreement that must be implemented. Also, before the golf course is opened for use, the facilities (as approved by the Division) shall be constructed and operational, and the stormwater management plan (as approved by the Division) shall be implemented. The structural stormwater practices as approved by this Office as well as drainage patterns must be maintained in perpetuity. No changes to the structural stormwater practices shall be made without written authorization from the Division of Water Quality; 7. An additional condition is that a final, written stormwater management plan (including a signed and notarized Operation and Maintenance Agreement) to treat runoff from the clubhouse and golf maintenance facilities shall be approved in writing by this Office before the impacts specified in this Certification occur. Also, before any permanent building is occupied at the subject site, the facilities (as approved by this Office) shall be constructed and operational, and the stormwater management plan (as approved by this Office) shall be implemented. The structural stormwater practices as approved by this Office as well as drainage patterns must be maintained in perpetuity. No changes to the structural stormwater practices shall be made without written authorization from the Division of Water Quality; 8. Culverts required for this project shall be installed in such a manner that original stream profiles are not altered. Existing stream dimensions (including the cross section dimension, pattern, and longitudinal profile) are to be maintained above and below the locations of each culvert. Culverts shall be designed and installed to allow for aquatic life movement as well as to prevent head cutting of the streams. If any of the existing pipes are or become perched, the appropriate stream grade shall be re-established. If the pipes are installed in a perched manner, the pipes shall be removed and re- installed correctly. The culvert(s) shall not be installed in such a manner that will cause aggradation or erosion of the stream up -or down- . stream of the culvert(s). Existing stream dimensions (including the cross section dimension, pattern and longitudinal profile) are to be maintained above and below locations of each culvert. Native, woody vegetation and other soft stream bank stabilization techniques must be used where practicable instead of rip -rap or other bank hardening methods. If rip -rap is necessary, it shall not be placed in the stream bed, unless specifically approved by the Division of Water Quality. Installation of culverts in wetlands must ensure continuity of water movement and be designed to adequately accommodate high water or flood conditions; 9.

Any time an existing distribution line is improved, the facilities are being relocated to existing roadways when possible. This policy not only ' returns rights -of way to their original condition, but also helps improve reliability by placing the facilities in a better position to be patrolled and repaired. This also reduces the right-of- way cost by reducing the required trimming along distribution lines. Continued recloser maintenance on a three year cycle and reviewing loading on all reclosers on a 6 month schedule will reduce the total occurrence of outages and the amount of consumer outage time since improved sectionalizing reduces the numbers of affected members.

The plans were permitted and approved under Permit # WQ 0024460 by Marie Doklovic, P.E February 22 2005. This final certification is for the Phase 1 Sewer System including the collection system the intermediate pump station and force main to the waste water treatment plant. A number of minor adjustments to the originally submitted plans have been made due to field constraints and preferences of the owner/operator Heater Utilities. These changes are summarized below. None of the field changes result in a non compliance situation. Field Changes 1. The final pump used at the intermediate pump station was an ABS pump AFP 1048 instead of the originally permitted Flygt pump. This change was due to a preference by the operator of the system and there familiarity with maintaining ABS pumps. This revised pump still hits the required operating point on the system curve. 2. The layout of the intermediate pump station site is slightly different than that shown in the permitted plans with the wet well being located furthest from the road and the gas generator moving closer to the road. 3. The below ground backflow preventer assembly vault at the intermediate pump station was replaced with an above ground "Hotbox" unit. If you should have any questions, comments or need any additional information during your review please call. We appreciate your efforts to expedite permitting of these plans.

Provide discussion on phasing and current tributary (permitted) flow, or on how Certificate of Occupancies will be issued for homes that flow to the Bright's Creek Phase I Wastewater Treatment Facilities. 2. Provide a schedule of when the full certification for the Bright's Creek Wastewater treatment facilities will be issued. Please note that, based on the Engineer's Partial Certification of only 60,000 gpd at the Wastewater Treatment Facility and the collection system currently being permitted to construct 187,520 gpd, it is unlikely a permit will be issued to construct this additional tributary flow until the wastewater treatment plant is certified to handle the currently -permitted flow. 3. Please confirm this project is being connected to Phase II. If this is the case, adjust the permit application to reflect a permit modification to WQ0030347 (Phase II) instead of WQ0024460 (Phase I). 4. The certificates of Public Convenience and Necessity need to be submitted with the responses to these conunents. Calculations: 1. Provide a profile drawing starting from lot 2205 (in phase 2A), showing the expected path through Phase I and Phase II of the collection system, taken to reach the wastewater treatment plant. This drawing should be on an 11 x 17 sheet of paper with the elevation scale maximizing the size of the paper. 2. Provide an engineering calculation (E1 analysis check), showing that the lowest elevated pump being requested in this application can compete with the highest elevated pump, duplex/triplex operating pressures, and friction in the system. Specifications: 1. Testing of the system states the test pressure will be 100 psi at the low point of the section under test. These sections should be identified to ensure that 1.5 times the typical operating pressure is represented in the test. 1 of 2 Plans 1. Update sheet SSO, showing all the low pressure collection lines serving Phase I and Phase II, and also showing on each lot (all phases), its lot number, zone number and elevation. 2. Update General note #6 on sheet SS 1 to reflect the minimum separation distances identified in 15A NCAC 02T.0305(f). 3. Provide the inside diameters of the 2-inch hdpe pipes being referenced. 4. Provide information on the flushing mechanism to be used at Sta. 17+50, preliminary calculations, and availability of water if it is to be used. 5. Confirm lot 2003 is permitted under Phase H, and should not be included in Phase IIA. The service connection showed on sheet SS 1 is not clear. 2of2 Michael F.
