Dennis Brown Excavation installed the system. The OWTS design is based on 3-bedrooms. An average daily wastewater flow of 450 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 1000-gallon, two-compartment Norwesco® poly septic tank with an Orenco® 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 gravelless chamber trenches. The distribution box was accessible from grade and had flow equalizers installed on each outlet pipe in the distribution box to assure equal flow to each trench. Each trench consists of 12 ARC ‘ADS’ chambers for a total of 48 chambers and 720 square feet of infiltrative area. There was at least 4-feet of undisturbed soil between each trench. Inspection ports were installed at the beginning and end of each trench. Ports may be cut to grade and placed in sprinkler boxes 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. 7-26-2022 Please call with questions. Sincerely, CBO Inc.

The property is located outside of Basalt, in an area where OWTSs are necessary. Legal Description: Subdivision: ASPEN MESA EST REFILE 8-13 Block: B Lot: 8 Parcel ID: 2391-273-02-006 SITE CONDITIONS The property is currently undeveloped. A 2-bedroom residence is proposed with a future bedroom contemplated. The residence will be served potable water from a community water system. The water line will enter the property from Escalate to the north and no OWTS component will come within 25-feet of the water line. The property slopes to the south west with an approximate 10% slope. The proposed soil treatment area (STA) is covered with native grasses and is an open field area. 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 on March 15, 2021 by digging two soil profile test pit excavations (Test Pits). A visual and tactile soil analysis was completed by Carla Ostberg at the time of excavation.1 The materials encountered in Test Pit #1 consisted of dark brown topsoil to 2.0-feet, underlain by light brown calcareous clay matrix to a to a maximum depth explored of 5.0-feet where digging became difficult. No bedrock or groundwater was encountered. The materials encountered in Test Pit #2 consisted of dark brown topsoil to 2.0-feet, underlain by light brown calcareous clay matrix to a maximum depth explored of 6.0-feet where digging become difficult. No bedrock or groundwater was encountered. 1 Carla Ostberg holds a Certificate of Attendance and Examination from the CPOW Visual and Tactile Evaluation of Soils Training. Page 2 A sample of the soil was taken from Test Pit #2 at 3-feet below grade. Soil structure grade was moderate to weak. The soil formed a ball and a ribbon less than 1-inch before breaking. Soil structure shape was blocky and consistence was friable. Soil texture was more smooth than gritty. Soils are consistent with Soil Type 2A. A long term acceptance rate (LTAR) of 0.5 gallons per square foot, will be used to design the OWTS. View of the property from Escalante Test Pit #1 Page 3 Test Pit #1 Backfill Page 4 Test Pit #2 Page 5 Test Pit #2 Backfill Sieved sample Ribbon less than 1-inch before breaking Page 6 DESIGN SPECIFICATIONS Design Calculations: Average Design Flow = 75 GPD x 2 people/bedroom x 3 Bedrooms = 450 GPD LTAR = 0.5 GPD/SF 450 GPD / 0.5 GPD/SF x 1.0 (gravity trenches) x 0.7 (chambers) = 630 SF The new OWTS design is based on 3-bedrooms. An average daily wastewater flow of 450 GPD will be used. For the purposes of this OWTS design, Benchmark Elevation at grade 7224’ (Lower Level Finished Floor) has been established as 100’. 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 72’ / min. 2% fall / min. 18” fall Automatic Distributing Valve / Distribution Box Approximate horizontal distance 25’ / min. 1% fall / min. 3.125” fall Infiltrative Surface (to farthest trench) Approximate horizontal distance 14’ / min. 1% fall / min. 1.75” fall *Elevations are based upon standard OWTS installation practices. Component elevations may change during installation due to site conditions. 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 1000-gallon, two compartment Infiltrator® poly septic tank with an Orenco® Effluent Filter on the outlet tee. 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 gravelless chamber 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 bed. Each trench will consist of 14 ‘Quick 4’ Infiltrator® chambers for a total of 56 chambers and 672 square feet of infiltrative area. There must be at least 4-feet of undisturbed soil between each trench. Inspection ports must be installed at the beginning and end of each trench. Ports may be cut to grade and placed in sprinkler boxes for access. 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. Page 7 COMPONENT MANUFACTURER MODEL NO. COMMENTS Septic Tank Infiltrator® IM 1060-2CP Two-compartment poly septic tank Biotube Effluent Filter Orenco® Full Size Effluent Filter and housing Tank Risers and Lids Orenco® Double-walled PVC Risers and Lids (24” diameter) Distribution Box Polylok Poly distribution box, lid, risers, and (4) flow equalizers Chambers Infiltrator® 56 ‘Quick 4’ Chambers 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. 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. Page 8 4-27-2021 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. 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. 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.
