The 5.21-acre property is located outside of Carbondale in an area where OWTSs and wells are necessary. Legal Description: Section: 32 Township: 7 Range: 87 A TR IN LOT 19 & 10 CONT 5.96 AC LESS RR ROW .75 AC, NET. Parcel ID: 2391-321-00-042 SITE CONDITIONS The property is currently developed with a 4-bedroom residence. The existing OWTS consists of a 1500- gallon, 2-compartment concrete septic tank followed by a 36-inch diameter concrete pump chamber with an Orenco® duplex pumping system. Effluent is pumped via a 1.25” diameter pump line to a 12’ x 80’ mounded sand filter with a minimum of 2-feet of sand filter material. Distribution consists of 4-inch diameter laterals set on 6-inches of gravel. Garfield County Individual Sewage Disposal System (ISDS) 3961 documents the system. The permit received final approval on March 21, 2005. Sopris Engineering design dated October 30, 2003 and As-Built documents dated March 21, 2005 are enclosed. Page 2 DESIGN SPECIFICATIONS There is an existing pond that appears to extend from the house foundation to approximately 15-feet from the primary septic tank. It has been reported to us that the pond is lined. The pump chamber replacement will be in the same approximate location as the existing pump chamber, as there are no reasonable alternatives for relocation of the pump chamber. We recommend examining the pond liner to ensure there are no leaks when the water can be re-routed or turned off in this area. The existing 1500-gallon, two-compartment septic tank appears to be water-tight. The 36-inch diameter concrete pump chamber is in poor condition and water infiltration may be occurring. Additionally, the electrical connections for the pumping system were located in the riser and were not water-tight. There was significant debris in the pump chamber, as well. Considering these conditions, we are recommending a new, 500-gallon, single-compartment concrete pump chamber, anchored with Deadmen, be installed in the same approximate location as the existing pump chamber. The existing pump chamber must be abandoned by crushing the top, bottom and sides and filling the void with onsite material or removing the concrete. A new, Orenco® Biotube Pump Vault, internal and external splice box, float tree, effluent filter, and discharge assembly (typically all things included in the Orenco® ProPak, with the exception of the control panel). Two new PF300511 pumps will be installed. Either the existing control panel will be used or a new Orenco® Duplex Control Panel will be installed. An Orenco® riser must be installed, in a water-tight fashion, to bring access to or just above grade. The elevation of the new pump chamber must align with the sewer line exiting the existing 1500-gallon septic tank and the 1.25-inch diameter pump line to the existing mounded sand filter. The control panel for the pump must be mounted on the existing post near the septic tanks. We recommend Valley Precast out of Buena Vista be contracted for start-up of the pumping system.

PERMIT APPLICATION INSTRUCTIONS An OWTS Permit Application must be submitted to Garfield County Environmental Health Department. https://www.garfield-county.com/environmental-health/filesgcco/sites/16/OWTS-Application-Complete- Packet-Dec.-2019.pdf. If the OWTS Permit Application will be submitted with a Building Permit Application, it should be submitted directly to Garfield County Building Department. All questions regarding permit submission can be directed to Garfield County Environmental Health Department, 970-945-6614 x8150. Page 4 INSTALLATION CONTRACTOR CBO Inc. expects that the installer be experienced and qualified to perform the scope of work outlined in this design. The installer must review this design thoroughly and coordinate with our office in advance of installation. Any additional conditions in this design or county permit must be completed and documented prior to final approval of the OWTS installation. Communication between the installer and this office is expected throughout the installation. INSTALLATION OBSERVATIONS CBO Inc. must view the OWTS during construction. The OWTS observation should be performed before backfill, after placement of OWTS components. Septic tanks, distribution devices, pumps, dosing siphons, and other plumbing, as applicable, must also be observed. CBO Inc. should be notified 48 hours in advance to observe the installation. In an effort to improve the accuracy of the record drawing, we request that the installer provide a sketch of the installation, including path of the sewer lines, water line installation (if applicable), septic tank location, STA location, and measurements from building corners or another fixed objects on the property. This sketch is most easily provided on Sheet W2.0 of the OWTS Design Packet. Photographs of the installation and final cover are also requested to supplement our installation documentation. REVEGETATION REQUIREMENTS An adequate layer of good quality topsoil capable of supporting revegetation shall be placed over the entire disturbed area of the OWTS installation. A mixture of native grass seed that has good soil stabilizing characteristics (but without taproots), provides a maximum transpiration rate, and competes well with successional species. No trees or shrubs, or any vegetation requiring regular irrigation shall be placed over the STA. Until vegetation is reestablished, erosion and sediment control measures shall be implemented and maintained on site. The owner of the OWTS shall be responsible for maintaining proper vegetation cover. OPERATION INFORMATION AND MAINTENANCE The property owner shall be responsible for the operation and maintenance of each OWTS servicing the property. The property owner is responsible for maintaining service contracts for manufactured units, alternating STAs, and any other components needing maintenance. Geo-fabrics or plastics should not be used over the STA. No heavy equipment, machinery, or materials should be placed on the backfilled STA. Machines with tracks (not wheels) should be used during construction of the STA for better weight distribution. Livestock should not graze on the STA. Plumbing fixtures should be checked to ensure that no additional water is being discharged to OWTS. For example, a running toilet or leaky faucet can discharge hundreds of gallons of water a day and harm a STA. If an effluent filter or screen has been installed in the OWTS, we recommend this filter or screen be cleaned annually, or as needed. If the OWTS consists of a pressurized pump system, we recommend the laterals be flushed annually, or as needed. The homeowner should pump the septic tank every two years, or as needed gauged by measurement of solids in the tank. Garbage disposal use should be minimized, and non-biodegradable materials should not be placed into the OWTS. Grease should not be placed in household drains. Loading from a water softener should not be discharged into the OWTS. No hazardous wastes should be directed into the OWTS. Mechanical room drains should not discharge into the OWTS. The OWTS is engineered for domestic waste only. Page 5 ADDITIONAL CONSTRUCTION NOTES If design includes a pump, weep holes must be installed to allow pump lines to drain to minimize risk of freezing. The pump shall have an audible and visual alarm notification in the event of excessively high- water conditions and shall be connected to a control breaker separate from the high-water alarm breaker and from any other control system circuits. The pump system shall have a switch so the pump can be manually operated. Excavation equipment must not drive in the excavation of the STA due to the potential to compact soil. Extensions should be placed on all septic tank components to allow access to them from existing grade. Backfill over the STA must be uniform and granular with no material greater than minus 3-inch. LIMITS: The design is based on information submitted. If soil conditions encountered are different from conditions described in report, CBO Inc. should be notified. All OWTS construction must be according to the county regulations. Requirements not specified in this report must follow applicable county regulations. The contractor should have documented and demonstrated knowledge of the requirements and regulations of the county in which they are working. Licensing of Systems Contractors may be required by county regulation. Please call with questions. Sincerely, CBO Inc.

October 30, 2003 James & Kathleen Duke 17111 Highway 82 Carbondale, Colorado 81623 RE: Onsite Wastewater System Improvements Design, Duke Residence, 256 Flying Fish Road, Garfield County, CO SE Job No. 23124.01 Dear James & Kathleen: Pursuant to your request, attached herewith is a letter presenting our findings in regard to the feasibility of design and approval of an engineered Onsite Wastewater System (OWS) for the above referenced Site. The feasibility and verbal approval by the county to proceed with design recommendations are based on current knowledge of the existing ground water levels, observation of the site conditions and information provided by others for use in supporting your application to Garfield County. It is our understanding that Garfield County will allow improvements on the site and will permit a system under current accepted guidelines. Our design reconunendations are feasible with respect to current and proposed land use, setback issues and estimated groundwater levels. Our recommendations are in accordance with Garfield County and the State of Colorado ISDS Regulations. We are including a detailed description of the system in this letter and have attached a site plan and details as a part of our scope of work. Conclusions Based on our findings we believe that the design and installation of an improved OWS system is feasible in accordance with Garfield County Regulations and the State of Colorado. We assume the system will serve the needs of an equivalent 4-bedroorh single-family home. Our design recommendations for an OWS include the installation of a 1500 -gallon concrete septic tank equipped with a duplex pump biotube vault dosing assembly and associated piping and controls. The treated effluent will discharge to a mounded gravel and pipe bed type soil absorption system. The soil absorption system will provide secondary treatment of wastewater for infiltration into the ground. The system will meet all required standards and setbacks for an absorption bed system. The mounded bed absorption system can be installed over the native sub soils. The system will meet all required setbacks and be installed within the general boundaries indicated on the plan. Our design is outlined below and delineated on the attached site plan. Site Location The subject site is located at 256 Flying Fish Road south of State Highway 82, in Garfield County, Colorado. The site is situated in Section 32, T 8 S, R 87 W of the 6"1 P.M. The Site comprises approximately 6 acres. The site is bounded by agricultural/riparian lands, the Roaring Fork River and adjacent single-family acreages. 502 Main Street • Suite A3 • Carbondale, CO 81623 • (970) 704-0311 • Fax (970) 704-0313 CAOR1Q ruf_'1urrR1uf: 1 1 e i James & Kathleen Duke SE Job No. 23124.01 October 30, 2003 Page 2 Existing Site Conditions The site is located on a relatively flat lower river bench sloping to the south to the Roaring Fork River. The site has an existing house and 2 small sheds. The existing ground surface in the proposed septic development area ranges from 1% to 2%. An irrigation ditch crosses through the property. The developed site and undisturbed areas are covered with grasses, weeds, scattered evergreen, cottonwood and aspen trees. Base Flood Elevation Review of the FEMA, FIRM map (panel 33 of 325, 0802051880 B) dated January 3, 1986 indicates that the 100 -year base flood elevation at the site ranges between is 6320 to 6321 feet (msl). The interpolated base flood elevation at the assumed upstream corner of the proposed house and absorption field mound is approximately 6320.5 feet (msl). Proposed Site Conditions It is our understanding that you intend to remodel and construct a new addition to the existing home. The house will have a total of 4 -bedrooms. The proposed improvements will include a new -mounded absorption field and septic tank with a pump dosing assembly. The proposed field location, grades, soil and site conditions will be further evaluated during construction to confirm assumptions made in the following design recommendations. The new facilities are to be generally located as shown on the plan. Subsurface Conditions Based on our knowledge of the general area, observations of onsite excavations, and geotechnical evaluations performed in the area. The subsoil encountered at the site generally consists of one to two feet of topsoil overlying 1-2 feet of sandy silty clay and clayey sands underlain by gravel alluvium with cobbles. Groundwater was observed at a depth of 1-2 feet below the surface. Additional geotechnical evaluations will be performed during pre construction and during construction of the system to provide recommendations for subsoil preparation, soil replacement as needed and placement of imported fill materials. The OWS is designed based on the utilization of imported sand filter material and recovery of the treated effluent by percolation into the native soils. James & Kathleen Duke SE Job No. 23124.01 October 30, 2003 Page 3 Design Criteria The remodeled residence will be a 4 -bedroom house. The design flow is calculated as follows: The new OWS shall be based on a minimum of 4 -bedrooms Residence unit - 4 bedrooms @ 2 person /bedroom = 8 person From the State I. S. D. S. Regulation: Max. Design flow (Qd) = # of people x 75(avg. flow gal/person/day) x 1.75 = gal/day Gallons per day for the subject house = 75 gal/person/day Qd = 8*75*1.5 =900 gaUday Septic Tank Design Per regulations Qd = 900 gal/dav Volume (V) of tank = Design Flow * 1.25 30 hour retention time) V = 900 gal/day * 1.25 = 1125 Use one 1500 -gallon septic tank Use a double chamber concrete tank with a filtered dosing pump system and controls. The tank must have appropriate access openings with watertight risers and lids. The tank shall be installed with additional dead weight for bouncy compensation. Mounded Absorption Field Design A site plan is provided to detail the various components of the proposed onsite wastewater treatment system. The location of the proposed absorption field system is outside of the floodplain however; a mound system needs to be built high enough so the system functions during seasonal high groundwater conditions. We have designed the mound with the top approximately 5 feet above the high ground water observed below the existing surface grade and the theoretical maximum base flood stage. The bottom of the distribution layer is 4 feet above the theoretical maximum base flood stage to be consistent with regulations requiring a 4 -foot separation from seasonal high ground water. The following information details the technical criteria utilized in design of a proposed system. The existing surface and sub grade at the proposed location of the mound system shall be prepared to provide an effective interface between the subsoil and the imported mound material. The topsoil shall be scraped away and used for the final top cover over the new mound. The existing subsoil shall be scarified and/or replaced with suitable imported material as needed to insure effective percolation of treated effluent into the subsoil. This soil preparation will be based on additional observations and evaluations during construction. The preparation and fill materials shall be approved by the engineer. James & Kathleen Duke SE Job No. 23124.01 October 30, 2003 Page 4 Proposed Absorption System The system will utilize a mounded sand filter system with imported sand and other suitable fill material. Area required for treatment bed in a mound system: Long Term Acceptance Rate method (LTAR) Using imported course sand media yields the minimum area: LTAR maximum loading rate for sand filter = 0.95ga1/S.F./day A=OJLTAR = 900/0.95 = 948 sq. ft. Use: Minimum 12' x 80' mounded absorption field or dimensions to obtain 950 sq. ft. minimum. Inspection ports shall be installed at the terminal ends of the new 4" perforated distribution pipes. The vertical inspection ports shall be 4" SDR 35 or schedule 40 pipe extending at least 6" above the surface. This will allow for checking the performance of the system. In regard to the current conditions, the septic tank, risers and sewage lines must be watertight to avoid discharge of effluent and infiltration of water into the system during high ground water or extreme flood events. Based on evaluation of the site it is assumed that the proposed septic tank will be in place with variable water table levels. Therefore the tank needs to have buoyancy protection by installation of appropriate dead weight anchors with cables and/or use of an 8" concrete lid. More detailed recommendations for buoyancy compensation will be made during final layout of the system. The mound needs to be graded to prevent surface water runoff from collecting on or around the mound. Effluent Dosing Distribution System A septic tank effluent pump system will be utilized to transport effluent to the distribution manifold at the head of the distribution lateral in the bed. We recommend the use of an Orenco Systems BioTube pump vault system or approved equal. The pump system shall incorporate a duplex pump system to insure continuous operation in the event that one pump fails to operate. The controls shall provide for alternate operation of each pump. Automatic float switches including a high water float with alarm shall be incorporated in the system. The pump assembly and dosing chamber will be installed in the secondary compartment of the septic tank. The vault will utilize a maintainable effluent filter. The transport line from the dosing pump to the absorption field shall be schedule 40 PVC with a maximum diameter of 1.25 inches. The transport line will be installed to allow the drain back of effluent to the dosing chamber. The mounded bed will be pressure dosed through the distribution header pipe. The pressure will reduce to gravity distribution through the individual 4" perforated distribution laterals running the length of the bed. The perforated pipe will be SDR -35 pipe with the orifices oriented downward. A 4" inspection port will be installed at the terminal end of the distribution laterals. The effluent pump shall be sized to pump at a minimum velocity of 4 ft/sec. The dosing volume shall not exceed 150 gallons. James & Kathleen Duke SE Job No. 23124.01 October 30, 2003 Page 5 OWS Operation and Maintenance All components of the engineered OWS shall be inspected on a regular basis and be properly maintained. The system and responsibility for repair and maintenance of the system will remain with the Owner. The OWS should require minimal maintenance. Several factors influencing the need for maintenance include: actual wastewater flows versus design flows, the volume of kitchen/domestic waste (excluding human waste and toilet paper), excessive household chemicals and other toxic liquids. The tank, absorption field and other system components should be visually inspected bi-annually for debris, damage, leaks, or other potential problems. In general, for a properly utilized system, septic tanks should be pumped and inspected every 2 - 4 years. The effluent filters should be cleaned every six months and at the time of pumping. Absorption fields should be maintained with suitable cover and kept free of root invasive plants. Positive surface drainage away from the absorption field should be maintained. Construction and Inspections Prior to construction of the permitted system the engineer should be contacted by the contractor and owner well in advance to provide adequate time to discuss the system components with the contractor, answer questions, resolve any conflict issues and schedule inspection site visits based on construction progress. County Regulations require that the Design Engineers of record perform site inspections of the permitted system during construction and provide "As -Built" documentation of the installed system to the County after construction is complete. General Notes 1) All materials and installation practices shall conform to County and the State of Colorado Individual Sewage Disposal Regulations. 2) All sewer lines and distribution lines in the system shall be 4" Schedule 40 or SDR -35 PVC unless specified otherwise on the plans. 3) Add a two-way clean out on the service line from the proposed house addition. 4) The contractor shall ensure that the concrete septic tank, risers and sewer lines are watertight. 5) The mounded bed area must be protected to prevent damage from vehicular or livestock traffic and must be crowned to divert drainage runoff away from the bed. 6) A maximum 3 -foot separation distance shall be maintained between perforated distribution pipe laterals. 7) A pressurized distribution manifold header pipe shall be installed at the head of the field to insure equal distribution to individual 4" perforated distribution laterals. 8) The treatment and distribution media shall be 3/4' to 1 'h" clean screened rock. 9) The sand material utilized in the mounded absorption bed shall have an effective size between 0 25 mm and 0.6mm. The uniformity coefficient shall be 4.0 or less. 10) A final cover of soil suitable for vegetation, a minimum 4" deep, shall be placed to the finished surface grade. The mound shall be planted (sod or mulch seeding) with suitable vegetative cover. James & Kathleen Duke SE Job No. 23124.01 October 30, 2003 Page 6 11) Fill utilized in constructing the mound must be clean suitable fill consistent with local material and allow for percolation rates between 10 to 20 minutes per inch. Fill materials to be approved by the engineer. 12) The Septic tank needs to be anchored to prevent movement during extreme flood events when groundwater may be present. Our design and recommendations are based upon data supplied to us by others. If subsurface or site conditions are found to be different from those presented in this report, we should be notified to evaluate the effect it may have on the proposed ISDS. If the County Environmental Health Department requests changes or modifications to this design, we should be contacted to evaluate the effect on the ISDS. If you have any question or need any additional information, please call. Sincerely, SOPRIS ENGINEERING, LLC Paul E. Rutledge March 21, 2005 James & Kathleen Duke 17111 Highway 82 Carbondale, Colorado 81623 RE: AS -BUILT OWS - Duke Property House Addition — Duke Residence, 256 Flying Fish Road, Garfield County, CO SE Job No. 23124.01 Dear James & Kathleen: Pursuant to requirements, this letter provides documentation that a new Onsite Wastewater System (OWS) was recently installed at the above referenced site. Sopris Engineering inspected the new -mounded sand filter/absorption bed at various times during construction prior to final backfill. The new -mounded sand filter/absorption bed was constructed in general compliance with the permitted design. The system constructed on site was designed and built to serve the needs of the 4 -bedroom house. Sopris Engineering performed visits to inspect and verify the material specifications and the distribution components associated with the treatment and absorption system. The new OWS components also include a 1500 -gallon concrete septic tank, and 36" diameter concrete dosing basin manhole structure and a duplex pump system. The mounded sand filter/absorption System and a 1500 -gallon dual compartment concrete septic tank was installed in accordance with Garfield County Regulations; the design specifications presented in the Sopris Engineering design drawing dated October 29, 2003 and the report dated October 30, 2003. The mound absorption field was constructed in an alternate location parallel with the north lot line. The 990 sq. ft Sand Filter/absorption field was constructed as a mounded gravel and pipe bed type sand filter absorption system. The pipe and gravel distribution layer was installed over 24" of filter sand. Suitable pit run type material fill was placed as needed below the sand filter to raise the level of the mounded bed to an appropriate height above the seasonal high ground water and the 100 -year flood plain. The Sand filter/absorption bed was installed level. Inspection ports were installed on each corner of the bed. The average depth at the top of the sand from existing ground is approximately 4 feet. The exposed soils after grubbing were suitable and consistent across the field. The distribution gravel was covered with filter fabric and a minimum of 12 inches of backfill was placed to the finish grades that have been shaped to provide drainage off the bed. Appropriate grading around the mound is complete with approximate side slopes at 3:1 The effluent is pumped from the dosing tank through a pressurized 1.25" transport pipe that splits to 4 individual distribution lines installed in the mounded field. The minimum setback distances have been maintained. The average 100 -year flood water level has been estimated to be at site elevation of 6320. The top of the sand layer and bottom of the distribution layer, in the mounded bed is at an approximate elevation of 6324.5 approximately 4.5 above the average flood elevation. A 36" diameter concrete dosing basin manhole structure was installed with a duplex pump vault dosing system with automatic controls. OWS Operation and Maintenance All components of the engineered OWS shall be inspected on a regular basis and be properly maintained.

The OWS should require minimal maintenance. Several factors influencing the need for maintenance include: actual wastewater flows versus design flows, the volume of kitchen/domestic waste (excluding human waste and toilet paper), excessive household chemicals and other toxic liquids. The tank, sanitary tees and effluent filter should be visually inspected bi-annually for clogging debris, damage, leaks, or other potential problems. In general, for a properly utilized system, septic tanks should be pumped and inspected every 2 - 4 years. The effluent filter should be cleaned every six months and at the time of pumping. Absorption fields should be maintained with suitable vegetative cover and kept free of root invasive plants. Positive surface drainage away from the absorption field should be maintained. If you have any question or need any additional information, please call. Sincerely, SOPRIS ENGINEERING, LLC Paul E.

And its patented pump vault technology eliminates the need for separate dosing tanks. This document provides detailed information on the ProPak pump vault and filter, 4-in. (100-mm) 60-Hz turbine effluent pump, and control panel. For more information on other ProPak components, see the following Orenco technical documents: • Float Switch Assemblies (NSU-MF-MF-1) • Discharge Assemblies (NTD-HV-HV-1) • Splice Boxes (NTD-SB-SB-1) • External Splice Box (NTD-SB-SB-1) Applications The Biotube ProPak is designed to filter and pump effluent to either gravity or pressurized discharge points. It is intended for use in a septic tank (one- or two-compartment) and can also be used in a pump tank. The Biotube ProPak is designed to allow the effluent filter to be removed for cleaning without the need to remove the pump vault or pump, simpli- fying servicing. Complete packages are available for on-demand or timed dosing sys- tems with flow rates of 20, 30, and 50-gpm (1.3, 1.9, and 3.2 L/sec), as well as with 50 Hz and 60 Hz power supplies.

Using a Pump Curve A pump curve helps you determine the best pump for your system. Pump curves show the relationship between flow (gpm or L/sec) and pressure (total dynamic head, or TDH), providing a graphical representation of a pump’s optimal performance range. Pumps perform best at their nominal flow rate — the value, measured in gpm, expressed by the first two numerals in an Orenco pump nomenclature.
