Dennis Brown installed the system. The OWTS design is based on 4-bedrooms (3 bedrooms in the residence plus a future bedroom). An average daily wastewater flow of 525 GPD was used. The 4-inch diameter SDR 35 sewer line exiting the residence has a double-sweep clean out and a minimum 2% grade to the septic tank. The system installation included a 1250-gallon, two-compartment concrete Norwesco® poly septic tank with an effluent filter on the outlet tee. This filter must be cleaned annually, or as needed. Risers bring the manhole lids to grade for access. Effluent gravity flows to a distribution box and then to four 3’ wide x 52’ long trenches. The distribution box is accessible from grade with flow equalizers. Each trench has 6-inches of sand filter material placed in the trench excavation. One 39-inch wide GeoMat™ sheet was placed on top of the sand filter material in each trench. A 4-inch diameter perforated pipe runs down the center of the GeoMat™, under the top layer of fabric. Each trench has a total of 52 linear feet of GeoMat™ for a total of 208 linear feet of 39” GeoMat™ and 624 square feet infiltrative area. Inspection ports were installed at the beginning and end of each trench. Ports may be cut to grade and covered with a sprinkler box for access. The OWTS was generally installed according to specifications. This observation is not a guarantee of workmanship and/or parts and materials. CBO Inc. should be notified if changes are made to the OWTS in the future. Any additional OWTS construction must be according to the county regulations. LIMITS: Observations are limited to components that are visible at the time of the inspection. The installer must have documented and demonstrated knowledge of the requirements and regulations of the county in which they are working. The quality of the installation is dependent on the expertise of the installer, soil type, and weather conditions. Please call with questions. Sincerely, CBO Inc.

The property is located outside of Basalt, in an area where OWTSs are necessary. Legal Description: Subdivision: OAK RIDGE I Lot: 1 BK-0640 PG-0585 DC 04-06-93 Parcel ID: 2391-224-03-001 SITE CONDITIONS The property is currently undeveloped. A 3-bedroom, single-family residence with the potential for an additional bedroom in the future is proposed. The residence will be served potable water from a community water system. No water line will come within 25-feet of any OWTS component. The proposed soil treatment area (STA) will be located to the southwest of the proposed residence. The area has an approximate 10-12% slope to the southwest. There should be no traffic or staging of material over the future STA site to avoid compaction of soils prior to construction of the STA. SUBSURFACE The subsurface was investigated by Kumar and Associates and findings are documented in a report (enclosed) dated January 2, 2022, Project No 19-7-723. Test Pits 1, 2, and 6 were excavated for the purpose of determining feasibility of construction of the proposed STA. Pit 1 consisted brown topsoil to 1.0-foot, underlain by silty clay loam to clay loam to 4.5-feet, underlain by tan sand and gravel to a maximum depth of 6.5-feet. This horizon is described as sand and gravel, silty with cobbles and probably boulders, medium dense, slightly moist, tan basalt rock, calcareous, cemented. We typically describe this horizon as a calcareous clay matrix which grades as Soil Type 2. No bedrock or groundwater was encountered. Page 2 Pit 2 consisted of topsoil to 1.5-feet, underlain by silty clay loam to clay loam to 4.0-feet, underlain by tan sand and gravel to a maximum depth explored of 7.0-feet where practical digging refusal was encountered. No bedrock or groundwater was encountered. Pit 6 consisted of topsoil to 1.5-feet, underlain by silty clay loam to clay loam to 3.0-feet, underlain by tan sand and gravel to a maximum depth explored of 8.0-feet where practical digging refusal was encountered. No bedrock or groundwater was encountered. A sample of the clay loam horizon was taken from Pit 1 at 2.5 to 3.0-feet and consisted of 1% gravel, 20% sand, 51% silt, and 28% clay. A sample of the sand and gravel horizon (calcareous clay matrix) from Pit 2 at 7.0 to 7.5-feet and consisted of 23% gravel, 49% sand, 24% silt, and 4% clay. These findings are consistent with soils typical in this area of Missouri Heights. STA sizing will be based on Soil Type 2. A long term acceptance rate (LTAR) of 0.6 gallons per square foot will be used to design the OWTS, in accordance with Eagle County OWTS Regulation. Installation of the infiltrative area must occur just below the clay loam horizon, into the calcareous clay matrix. DESIGN SPECIFICATIONS Design Calculations: Average Design Flow = 75 GPD x 2 people/bedroom x 3 Bedrooms = 450 GPD + 75 GPD (4th bedroom) = 525 GPD LTAR = 0.6 GPD/SF 525 GPD / 0.6 GPD/SF x 1.0 (gravity trenches) x 0.7 (GeoMat™ with min. 6” sand) = 613 SF The OWTS design is based on 3-bedrooms in the residence + 1 future bedroom = 4 total bedrooms. An average daily wastewater flow of 525 GPD will be used. For the purposes of this OWTS design, Benchmark Elevation at grade 7263’ has been established as 100’ Main Level Finished Floor (FF). Lower Level FF is 90’ 10 ¼” (7253.85’). CBO Inc. should be notified of any discrepancies or problems with grade elevations of proposed components during installation of the OWTS. OWTS Component Minimum Elevation Primary Tank Inlet Invert Approximate horizontal distance 56’ / min. 2% fall / min. 14” fall Distribution Box Approximate horizontal distance 13’ / min. 1% fall / min. 1.625” fall Infiltrative Surface Approximate horizontal distance to furthest trench 24’ / min. 1% fall / min. 3” fall *Elevations are based upon standard OWTS installation practices. Component elevations may change during installation due to site conditions. Minimum grade refers to piping between components. The 4-inch diameter SDR 35 sewer line exiting the residence must have a double-sweep clean out and a minimum 2% grade to the septic tank. The system installation must include a minimum 1250-gallon, two-compartment concrete septic tank with an effluent filter on the outlet tee. Any state-approved poly septic tank or concrete septic tank may be Page 3 substituted. Risers must bring the manhole lids to grade for access. If more than one riser is added to the septic tank, an extension handle must be installed on the effluent filter. Effluent will gravity flow to a distribution box, and then to four 3’ wide x 52’ long trenches. The distribution box must be accessible from grade and must have flow equalizers, or similar product, installed on each outlet pipe in the distribution box to assure equal flow to each trench. Each trench must have a minimum of 6-inches of sand filter material placed in each trench over- excavation. Sand filter material must be clean, coarse sand, all passing a screen having four meshes to the inch. The sand must have an effective size between 0.15 and 0.60 mm. The uniformity coefficient must be 7.0 or less. Material meeting ASTM 33, for concrete sand, with three percent or less fines passing 200 mesh sieve may be used. A gradation of the sand media must be submitted to this office prior to obtaining the sand. One 39-inch wide GeoMat™ will be placed on top of the sand filter material on each trench. A 4-inch diameter perforated pipe will be placed down the center of the GeoMat™, under the top layer of fabric. Each trench will have a total of 52 linear feet of GeoMat™ for a total of 208 linear feet of 39” GeoMat™ and 624 square feet infiltrative area. All material associated with the GeoMat™ installation must be proprietary products associated with the GeoMat™, including the geotextile fabric. Manufacturer instructions must be followed regarding installation of the GeoMat™. There must be at least 4-feet of undisturbed soil between each trench. Inspection ports must be installed at the front corners of each trench to the side of the GeoMat™ and the end inspection ports will be tied onto the end of the laterals. Ports may be cut to grade and placed in sprinkler boxes for access. There shall be no cobble-sized (<2.5”) or greater rock in final cover over the GeoMat™. COMPONENT SPECIFICATIONS The component manufacturers are typical of applications used by contractors and engineers in this area. CBO Inc. must approve alternative components prior to installation of the OWTS. Requests must be submitted, in writing, to our office for approval prior to installation. Component technical data sheets are available upon request. COMPONENT MANUFACTURER MODEL NO.

Alternatives may be considered or recommended by contacting our office. Construction must be according to Eagle County On-Site Wastewater Treatment System Regulations, the OWTS Permit provided by Eagle County Environmental Health Department, and this design. 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 area. 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 2-21-2022 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.

(100-mm) Biotube Effluent Filters, Biotube Jr., Biotube Insert Filters, and Biotube Base Inlet Filters are ideal for residential septic tanks and have a lifetime warranty. They prevent large solids from leaving the tank, dramatically improving wastewater quality and extending the life of residential drainfields. Standard Features & Benefits • Alarm available, to signal the need for cleaning • Flow modulating discharge orifices available to limit flow rate leaving tank, mitigat- ing surges and increasing retention time • Custom and commercial sizes available Effluent from the relatively clear zone of the septic tank, between the scum and sludge layers, horizontally enters the Biotube Effluent Filter. Effluent then enters the annular space between the housing and the Biotubes, utilizing the Biotubes’ entire surface for filtering. Particles larger than the Biotube’s mesh are prevented from leaving the tank. Optional Features & Benefits Biotube Filtering Process 8-in. (200-mm) Base Inlet Filter 4-in.
