Dear Mr. and Mrs. Benderly; This letter is to inform you that the above referenced ISDS Permit has been inspected and finalized. Enclosed is a copy to retain for your records. This permit does not indicate compliance with any other Eagle County requirements. Your Advantex Treatment System requires regular maintenance by the contractor, Environmental Filtration Products, in order to function properly. Be aware that later changes to your building may require appropriate alterations of your septic system.

Dear Mr. and Mrs. Benderly: Hepworth-Pawlak Geotechnical, Inc. has observed the installation of the Individual Disposal System (ISDS) at Lot 3, Block 6, Lake Creek Meadows Subdivision. The ISDS components observed included: absorption area over -excavation, septic tanks, . effluent transport pipe and 'grades, distribution laterals, cleanout, manifold pipes, inspection ports, and the locations of all components. A 400 gallon single chamber dosing tank was used in place of the 500 gallon single chamber tank specified in the approved ISDS design dated September 25, 2003 because the 400 gallon tank is a non - seam monolithic concrete tank while the 500 gallon tank has a mid -seam. The distribution and manifold piping was installed as shown on Figure 5 of the approved ISDS design dated Septerrioer 25, 2003. The bridge abutment drain outlet pipe was extenThe and the drainage channel filled to .a distance of 57 feet from the absorption area. ISDS component locations are shown to scale on the attached Figure 1. The absorption area over -excavation was observed to be completed to depths where the underlying alluvial gravel deposits were encountered. Three to six feet of minus 6 inch pit run from the LaFarge pit in Eagle was placed in the excavation as import filter soil. A gradation analysis was performed on the import soil, prior to placement, to ensure that it met the project specifications. The gradation analysis of the minus 6 inch pit run is presented on Figure 2. In addition we reviewed a gradation analysis of the LaFarge Glenwood Springs 970-945-7988 0 Parker 303-841-7119 * Colorado Springs 719-633-5562 Jason and Monica Benderly July 8, 2004 Page 2 concrete sand and found it to be acceptable for use as the 2 foot thick sand filter overlying the import soil. A gradation analysis of the concrete sand supplied by LaFarge is presented as an attachment. The absorption area was installed to maintain at least a 5 foot separation to the existing groundwater conditions. Based on our observations made during the site visits it is our professional opinion that the ISDS was constructed in general accordance with the design plan. An ISDS plan view as -built, drawn to scale, is shown on the attached Figure 1. The sewer pipe and the effluent pipe from the Advantex AX-20 pod to the dosing tank were not observed because they were backfilled prior to our final visit. The Advantex components were installed by qualified professionals from SCG Enterprises and were not inspected by HP-Geotech. If you have any questions or if we may be of further assistance, please let us know. Sincerely, ]HEPWORTH - PAAW�LA�K GEOTECHNiCAL, INC.

Dear Mr. and Mrs. Benderly: As requested by the Eagle County Environmental Health Department, Hepworth- Pawlak Geotechnical, Inc. (H-P Geotech) has incorporated the ISDS design changes submitted in a letter dated June 9, 2003 to the Revised Individual Sewage Disposal System Design, dated June 4, 2003, Job No. 402 332, for the proposed residence at Lot 3, Block 6, Lake Creek Meadows Subdivision, located at 25 West Lake Creek Drive. The existing two bedroom residence has been demolished and the proposed new residence will have four bedrooms and a new ISDS. The original septic tank and absorption area gravel and soils should be removed and properly disposed of. The local landfill may accept the soils from the existing absorption area. The study was conducted in accordance with our agreement for engineering services to you dated December 10, 2002. The new ISDS will be located outside of the 100-year floodplain which was delineated by Tetra Tech, Inc. and shown on a site plan prepared by Range West, Inc. dated February 14, 2003. The data obtained and our recommendations based on the existing site conditions and the proposed residence are presented in this report. Percolation Testing: No percolation testing was performed because the shallow soils consist of uncontrolled fill and the aggregate used to construct the original absorption area trench. Two separate gradation analyses were performed to establish a long term acceptance rate (LTAR) for the fill subsoils in the proposed absorption area. Two Glenwood Springs 970-945-7988 0 Parker 303-841-7119 0 Colorado Springs 719.633-5562 Jason and Monica Benderly September 25, 2003 Page 2 Profile Pits were excavated at the locations shown on Figure 1. The soils exposed in the Profile Pits are shown on the Log of Profile Pits, Figure 2. In Pit 1 a thin veneer of topsoil overlies about 6 feet of man -placed, moist, medium dense clayey, silty, gravelly sand fill with roots and organics. The fill overlies a soft, organic, slightly clayey silt containing root material to the maximum depth explored of about 8 feet. The subsoils encountered in Profile Pit 2 consist of about 5 feet of man -placed, slightly clayey, silty, sandy gravel with cobbles and scattered boulders and debris overlying about 2 feet of organic, slightly clayey silt containing root material. Beneath the silt layer a slightly silty, sandy gravel with cobbles and boulders was encountered to the depth explored of about 8.5 feet. Gradation analyses were performed on two composite samples of the fill obtained from the proposed absorption zone. Based on the gradation analysis results, the soil classifies as a gravelly loam, see Figures 3A and 3B, in accordance with the United States Department of Agriculture (U.S.D.A.) textural classification system and has a LTAR of about 0.5 gallons per square foot per day in accordance with the Colorado State Board of Health, Guidelines on Individual Sewage Disposal Systems, Revised 2000. ISDS Analysis: Based on the limits of the 100-year flood plain, site setback constraints, site conditions and the lack of area for a future replacement ISDS, the new ISDS will consist of an Orenco Systems, Inc. (Orenco) Advantex AX-20 treatment system and a pressure dosed absorption area. The absorption area will be constructed by soil replacement. Because of the low LTAR rate of the fill soils and the presence of the existing absorption area, the existing soils in the proposed absorption area are not suitable for the loading rate required by the limited size of the project site. In addition, the existing septic tank is undersized and will be removed. Therefore, we propose to over excavate beneath the proposed absorption area to a depth of about 7 feet or until the natural alluvial gravels with a high acceptance rate are 402 332 Jason and Monica Benderly September 25, 2003 Page 3 encountered. No percolation testing was performed on the receiving soils due to their depth of about 7 feet below grade. It has been our experience that alluvial gravels typically have Long Term Acceptance Rates (LTAR) of 1.2 gallons per square foot per day or greater. A replacement soil consisting of a slightly silty to silty, sandy gravel with 35 % or greater by weight passing the No. 4 sieve and less than 15 % by weight passing the No. 200 sieve should be placed in the bottom of the over -excavation on the natural alluvial gravels. The fine graded soil particles passing the No. 200 sieve should be primarily silt, not clay. The replacement soil will be 2.5 to 3 feet thick and the specified gradation will coincide with the U.S. D.A. gradation for sand and loamy sand, suitable for an application rate of 1.2 gallons per square foot per day. A sand filter which is 2 feet thick will be placed over the replacement soil. Per the U.S. E.P.A. Design Manual, Table 7-8, a medium sand will be required to achieve an LTAR of 1.2 gallons per square foot per day. The gradation of the medium sand should meet the following requirements: > 25 % by weight particle size of 0.25 to 2.0 mm, < 35 % by weight particle size of 0.05 to 0.25 mm and < 10 % by weight of particle size of 0.002 to 0.05 mm. The combination of 2 feet of medium sand overlying about 2.5 to 3 feet of replacement soil in the over excavation will provide at least a 4 foot minimum separation to groundwater seepage. A revised Figure 6 is attached showing a cross-section of the proposed absorption area. The replacement soil and medium sand should be placed in 6 to 8 inch loose lifts and compacted by wheel rolling or track, to about 85 % of the maximum standard Proctor dry density (ASTM D-698). Care should be taken to ensure that the replacement soil is not over -compacted which could decrease its permeability. A site plan showing the proposed residence, proposed ISDS, property lines and the minimum horizontal distances of these features relative to the ISDS is shown on Figure 1. 402 332 Jason and Monica Benderly September 25, 2003 Page 4 Septic and Dosing Tanks: A water tight, concrete, 1,500 gallon, two chamber, septic tank designed for use with the Advantex Treatment System will be used for primary treatment of sewage from the residence. The treated effluent will be pumped to a 500 gallon water tight, single chamber, concrete, dosing tank. A submersible effluent pump will be used to dose the absorption area. Approved risers should be installed on septic tank access ports to allow easy access for maintenance. Septic tank riser lids should be insulated to provide frost protection. Riser lids must be installed no deeper than 8 inches below finished grade for easy access. All gaskets sealing the sewer pipe inlet, transport pipe outlet, riser to tank gaskets and riser lids should be water tight to ensure that shallow groundwater or flood waters do not enter the tank or treatment tanks. We have determined that a minimum of 4 feet of backfill soil needs to be placed over the top of the septic tank and dosing tank to counter act the buoyant force of groundwater on the tanks. If less than 4 feet of backfill soil is placed over the tanks, up lift of the tanks could occur when they are empty, such as after pumping the tanks empty for maintenance. Dosing Pump: An Orenco P5005, two stage, 115 volt effluent pump with a 1.25 inch diameter discharge assembly is suitable for this application. For design purposes, it was assumed that the elevation difference from the dosing pump intake to the distribution manifold in the absorption area is not more than 12 feet and that the transport pipe length is not more than 55 feet. The pump performance curve for the Orenco P5005 effluent pump is shown on Figure 7. The dosing pump will be controlled by floats set to provide a dose of about 120 gallons at a maximum frequency of approximately 9 doses per day. The actual dose volume applied to the absorption area is about 100 gallons, assuming an effluent drain -back volume of 20 gallons per dose. 402 332 Jason and Monica Benderly September 25, 2003 Page 5 AdvanTex Treatment System: An AdvanTex AX-20 treatment system installed in the 3B configuration will be used to ensure that high quality effluent is applied to the absorption area. The AdvanTex treatment system is sold as a package unit that includes component installation and three years of operation and maintenance. It is required that a maintenance contract with a certified AdvanTex maintenance company exist at all times because the system does require regular maintenance to function properly. The system should be observed for the first month of operation to ensure proper control settings and operation. Once "start-up" is completed a semi-annual observation of the system is required. During the semi-annual observations the septic tank sludge and scum accumulation should be measured and this data used to arrange a tank pumping schedule. The effluent quality should be observed to ensure that clear odorless effluent is dosed to the absorption area. In addition the air vent/inspection ports in the absorption area should be observed for any evidence of effluent ponding. If ponding is observed, the levels should be measured and recorded for future use. Sewer and Effluent Piping: The sewer line from the residence to the septic tank should not be less than the diameter of the building drain and not less than 4 inches in diameter. The portion of the sewer line extending from 5 feet outside the foundation should have a slope of at least 2 % except for the 10 feet of pipe immediately preceding the septic tank which must be sloped between 0.5% and 2%. Clean -out pipe should be installed in the sewer line adjacent to the foundation, adjacent to the septic tank, where the line bends at 90 degrees or more and at least every 100 linear feet of pipe throughout the length of the line. 90 degree bends should be accomplished with a pair of 45 degree elbows or a 90 degree clean sweep. Use of 90 Degree elbows is not approved. The transport pipe should be schedule 40 PVC and must be sloped to allow effluent to drain backto the dosing chamber when the pump switches off. This will prevent 402 332 Jason and Monica Benderly September 25, 2003 Page 6 effluent from freezing in the pipe. The absorption area manifold piping and distribution piping layout is shown on Figure 5. High water alarm switches should be installed above the high float position in the dosing tank and as part of the Biotube Pump Package in the septic tank. The high water alarm will provide audio and visual warning of a high water condition and should be placed inside the dwelling where it will be readily seen and heard. The highwater alarm must be wired on a circuit that is separate from the pump circuit. Absorption Area: The absorption area bed is designed to be 750 square feet based on a LTAR of 1.2 gallons per square foot per day for the medium sand replacement soil and ultimately the natural receiving gravels below. A 25 % reduction in the absorption area size was given for dosing because of the high quality of the effluent applied to the absorption area. The absorption bed has dimensions of 15 feet wide by 50 feet long. We should be contacted to sample and perform gradation analysis on the medium sand and replacement soil before placement to ensure that the gradations of the materials are suitable, unless the gradations are available from the supplier. Absorption area calculations are shown on Figure 4 and an absorption bed plan view is shown of Figure 5. The over excavation should be completed to a depth where all soils from the old absorption area, clayey fill and organic silts have been completely removed and the underlying alluvial gravels are exposed. Care must be taken during installation to ensure that the soils exposed in the bottom and sides of the over excavation are not compacted. In addition, the bottom and sides of the over excavation should be scarified prior to placing the 2.5 to 3 feet of replacement soil. The replacement soil and the 2 feet of medium sand placed over it should be placed in 6 to 8 inch thick loose lifts. Each lift should be compacted, by wheel or track, to about 85 % of the maximum 402 332 G�~Pt�Ch Jason and Monica Benderly September 25, 2003 Page 7 standard Proctor dry density before placement of the next lift. An absorption area cross-section is shown on Figure 6 and the specific gradations of the fill materials used to construct the absorption area are discussed in the ISDS Analysis section of this report on pages 2 and 3. Mirafi 140N or equivalent geotextile should be placed over the aggregate containing the distribution pipe to help prevent clogging of the aggregate by fine soil particles. The total thickness of the soil cap over the mound, including topsoil, should be a minimum of 1.5 feet with any backfill side slopes graded at a slope of 311:1V or flatter. A minimum of 0.5 feet of topsoil, suitable to support vegetation, should be placed over the entire soil cap. It is important not to plant large vegetation in and around the absorption area and manifold piping as the roots may damage the distribution piping. We recommend that the topsoil cap be re -vegetated as soon as possible with a mountain meadow grass mix or suitable equivalent. A drainage swale should be constructed on the existing slope above the absorption area to divert surface water away from the absorption area. Combination air vent/inspection ports should be installed at each corner of the aggregate bed. We recommend "candy cane" style air vent/inspections ports so that the vent opening faces down towards the ground surface. The opening should be covered with #16 fly-tite screen. The top "candy cane" portion of the ports should extend a minimum of 8 inches above the topsoil cap over the absorption area and should be removable so that any effluent ponding can be observed and measured. The vent/inspection ports should be constructed of 4 inch diameter PVC pipe installed to the bottom of the aggregate bed. The bottom 12 inches of pipe which lies within the aggregate bed should be perforated. All piping and materials should meet the specifications of the Eagle County Land Use Regulations for Individual Sewage Disposal Systems. 402 332 Jason and Monica Benderly September 25, 2003 Page 8 ISDS Maintenance: The on -site ISDS and AdvanTex treatment system will require maintenance as specified by the manufacturer. The level of maintenance will vary with the complexity of the system and water use habits of the users. We recommend that fats, oils, greases, paint, solids, water softener backwash solution, water from hot tubs, and other constituents that can clog and foul collection and disposal equipment are not disposed of in the residence drains. It is critical that no water fixtures in the residence leak, which can hydraulically overload the system. The absorption area and any areas directly up gradient of it should not be watered excessively by lawn irrigation systems or other means as the soils may become hydraulically overloaded. The septic tank should be pumped as required by the AdvanTex maintenance contractor. The septage should be disposed of at an approved location. The high water alarm switches should be checked to ensure that they are working properly once a year. We recommend that the operation and maintenance manual be developed for the ISDS by the AdvanTex certified contractor. The ISDS should be operated and maintained as stipulated in the manual. Limitations: This design has been conducted in accordance with generally accepted engineering principles and practices in this area at this time. We make no warranty either express or implied. The conclusions and recommendations submitted in this report are based upon the data obtained from the Profile Pits excavated at the location indicated on Figure 1 and to the depths shown on Figure 2, the proposed type of construction, and our experience in the area. Our findings include interpolation and extrapolation of the subsurface conditions identified at the Profile Pits and variations in the subsurface conditions may not become evident until excavation is performed. If conditions encountered during construction appear different from those described in this report we should be notified at once so re-evaluation of the recommendations may be made. 402 332 Jason and Monica Benderly September 25, 2003 Page 9 The staked locations of the ISDS components are approximate and not for construction. We recommend that the position of the ISDS components, proposed residence and setback requirements be verified in the field by a Professional Land Surveyor licensed in the state of Colorado. Residences in this area are served by municipal water sources. The absorption area size and location was designed to allow for a 50 foot setback to the non potable springs located northeast and east of the proposed absorption area. No other suitable areas for the ISDS absorption area exist on the project site. The Eagle County Table of Minimum Horizontal Distances shows that a 100 foot setback is required from absorption areas to springs, wells and suction lines. Our interpretation of this setback is that the absorption area must be 100 feet minimum from drinking water sources because springs are grouped together with wells and suction lines which are both potable water supply methods for drinking water. The spring on the site is not considered potable and is not used for drinking water. Therefore, it is our opinion that the non potable spring is not any different from the other surface water on the property and the use of a 50 foot offset is suitable. Verbal approval was given by the Eagle County Environmental Health Department at the beginning of the project use a 50 foot surface water offset to the proposed absorption area. In addition, ISDS regulations in Summit County require only a 50 foot setback from absorption areas to non -potable springs. This report has been prepared for the exclusive use by our client for the ISDS design submittal process. We are not responsible for technical interpretations by others of our information. As the project evolves, we should provide continued consultation and field services during ISDS construction to review and monitor the implementation of our recommendations, and to verify that the recommendations have been appropriately interpreted. We recommend on -site observation of excavations, replacement soil placement, pipe and tank installation, and soil backfill placement by a representative of 402 332 Gam~P� Jason and Monica Benderly September 25, 2003 Page 10 the geotechnical engineer. Any field observations of the ISDS installation or other out of scope services will be provided at additional cost. Two stamped copies of this final report have been mailed to the Eagle County Environmental Health Department. It is the responsibility of the client or contractor to collect and dispose of the previous ISDS designs and ensure that the installation contractor has this most current ISDS design.

It is assumed that there are two (2) people per bedroom. The calculated design flow is 150% of the average daily flow which is calculated as follows: Q = (75)(4)(2)(1.5) = 900 gallons per day The absorption area, before reduction for dosing, was calculated using an LTAR of 1.2 gallons per square foot per day for the medium sand replacement so il, a design flow of 900 gallons per day and a 1.3 factor for the absorption bed as follows: A = 900 x 1.3 = 975 square feet 1.2 Because of the high effluent quality a 25% reduction will be allowed for dosing and the minimum _ absorption area was calculated as follows: A= 975 X 0.75 = 732 square feet A medium sand replacement soil absorption area designed to be 15 feet wide by 50 feet long totaling 750 square feet will be used. The two chamber, water tight, precast concrete septic tank, approved for used with the AdvanTex AX-20 should have a minimum effective liquid tank capacity of 1,500 gallons in accordance with the manufacturers recommendations. The dosing tank will be a 500 gallon, single chamber, water tight, concrete tank with a float controlled Orenco P5005 submersible effluent pump. The absorption area is designed to be 750 s quare feet. 402 332 HEPWORTH — PAWLAK OT 3, BLOCK 6, LAKE CREEK MEADOWS FIGURE 4 GEOTECHNICAL, INC_ IL ABSORPTION AREA CALCULATIONS 2" DIA.
