The 2.766-acre property is located outside of Glenwood Springs, in an area where OWTSs and wells are necessary. Legal Description: Quarter: SW Section: 25 Township: 5 Range: 90 A TR CONT 2.50 AC, ALSO A TR CONT. .22 AC. ALSO A TRACT OF LAND CONT. .046 AC.+/- AS DESC. IN RECEPTION # 858415. Parcel lD: 2123-253-00-046 SITE CONDITIONS There are two residences developed on the property: a 2-bedroom residence and a 1-bedroom cabin. Both are served by separate existing OWTSs. We were unable to find any documentation from Garfield County on either OWTS. lt should be noted that the Garfield County Assessor's website notes the 2- bedroom residence was built in 1969 and the 1-bedroom cabin in 1971 . The subject OWTS serving the 2-bedroom residence is slow draining and there is a desire to upgrade the system. The 1-bedroom cabin will continue to be served by the existing, OWTS' Potable water on the property is served by an existing well. The well ís located to the south of the 2- bedroom residence. The well is located within the 50-foot setback to the existing OW[S. Canyon Creek runs to the west of the residences within the western property boundary. The existing OW|S is located within the 5O-foot setback to the creek. With the proposed septic tank location within the S0-foot setback to both the creek and the well, it is recommended that a bitumastic coating be applied to the outside of the septic tank or a liner incorporated in the septic tank excavation, bedded with sand or pea gravel (or non-angular rock). Garfield County On-Site Wastewater Treatment System Regulations, Table 7-1, Note: states "For repair or upgrading of existing OWTS where the size of lot precludes adherence to these drsfances, a repaired OWTS must not be closer to setback features than the existing OWT9, as reviewed and approved by the local public health agency." There is also an irrigation and ditch and pond that is filled with irrigation water during the summer months. The proposed STA will be located at least 50-feet from the irrigation ditch and pond. lt should be noted that the pond may require mitigatlon to assure there is no over.flow when it is full as the Page2 proposed STA is downgradient of the pond and there is evidence that over-flow has occurred in the past. Photo of pond We do not find it feasible to locate the proposed septic tank outside of the required setbacks required for the well and the creek. The proposed soil treatment area (STA) will be located to the east of the resídences, outsíde of required setbacks. The proposed STA focatíon has an approxímate five percent slope to the west toward Canyon Creek. The proposed area is vegetated with native grasses. 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 16,2022 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.l The materials encountered in Test Pit #1 consisted of dark brown topsoil to 2.5-feet, underlain by medium brown to silty clay loam a maximum depth explored of 6.0-feet with increasing density below 5.5-feet. No bedrock or groundwater was encountered. The materials encountered in Test Pit #2 consisted of dark brown topsoil to 2.5-feet, underlain by medium brown to silty clay loam a maximum depth explored of 7.0-feet with increasing density below 6.5-feet. No bedrock or groundwater was encountered. A sample of the soil was taken from Test Pit #1 at 3-feet below grade. The soil formed a ball and a ribbon 1 to 2-inches in length before breaking. Soil structure shape was blocky and consistence was firm to extremely firm. Soiltexture was more smooth than gritty. Soilstructure grade was moderate, becoming more dense with depth. A shallow (approx. 2-feet below native grade) installation of the STA is proposed. STA sizing is based on SoilType 3, Silty Clay Loam with moderate structure grade. A long term acceptance rate (LTAR) of 0.35 gallons per square foot will be used to design the OWTS. 'Carla Ostberg holds a Certificate of Attendance and Examination from the CPOWVisualand Tactile Evaluation of Soils Training. Page 3 t .'4. - Test Pit #1 ¡j tt ¡d 'y Sieved sample * Ribbon length Page 4 Test Pit #2 View of Test Pit #2 looking toward Test Pit #l (looking south) DESIGN SPECIFICATIONS The existing OWTS serving the 1-bedroom cabin will remain. The existing septic tank serving the 2' bedroom residence will be pumped and the top, bottom, and sides crushed, and remaining void filled with onsite material or removed. The existing STA will be abandoned in place. Desiqn Calculations: Average Design Flow = 75 GPD x 2 people/bedroom x 2 Bedrooms = 300 GPD LTAR = 0.35 GPD/SF 300 GPD / 0.35 GPD/SF x 1.0 (pressured dosed bed) x 0.7 (chambers) = 5gg ga The new OWTS design is based on 2-bedrooms. An average daily wastewater flow of 300 GPD will be used. : i:li 'l Page 5 For the purposes of this OWTS design, Benchmark Elevation has been established as 100' as the elevation of the existing sewer line exiting the residence. CBO lnc. should be notified of any discrepancies or problems with grade elevations of proposed components during installation of the OWTS. *Elevations are based upon standard OWTS installation practices Component may change during installation due to site conditions. Minimum grade refers to piping between components. The sewer line exiting the residence must have a double-sweep clean out and a minimum 2% grade to the septic tank. This sewer line must also be encased as it comes within 50-feet from the existing well (See Encasement Detail W4.0i3). The system installation will include a 1O0O-gallon, two-compartment Valley Precast concrete septic tank wíth an Orenco@ Bíotube Pump Vault and an Orenc@ PF3005 pump in the second compartment of the septic tank. lf the septic tank will be in an area subiect to traffic, it must be traffic rated. The floats should be set to dose approximately 80 gallons each pump cycle, allowing approximately I gallons of drain back after each pump cycle. A pump curve is enclosed. The control panel for the pump must be located within line of sight of the septic tank. We recommend Valley Precast out of Buena Vista be contracted for start-up of the pumping system. A 1.S-inch diameter Schedule 40 pump line must be installed from the pump to an Orenco@ automatic distributing valve (ADV), model 6402. The elevation difference between the components must be verified to assure the pump curve was run properly (estimated 20-feet elevation difference). This pump line must have a minimum 1% grade for proper drain back into the tank after each pump cycle. The pump line that runs under the driveway and within the 50-foot well setback must be encased (See Encasement Detail W4.0i3). The ADV must be placed at a high point in the system in an insulated riserwith access from grade. Screened rock must be placed below the ADV to support the ADV and to assure the clear pipes exiting the ADV remain visible forfuture inspection and maintenance. Effluent will be pressure dosed through 1.S-inch diameter pipes to a gravelless chamber beds with four rows of 13 'Quick 4' Standard Plus Low Profile f nfiltrator@ chambers, for a total of 52 chambers and 624 square feet of infiltrative area. The ADV will divide the bed into two zones, each with 2 rows connected with a level manifold. Effluent will be pressure dosed to 1.S-inch diameter laterals, which must be hung with zip ties from the underside of the chambers. Laterals will have 5132-inch diameter orifices facing up, with the exception of the first and last holes facing down for drainage. Orenco@ Orifice Shields may be placed under each downward-facing orifice. The orifices must be placed 3-feet on center.

Valves may be placed in a valve box, accessible from grade, for access. lnspection ports must be placed at the beginning and end of each trench. Ports may be cut to grade and covered with a valve box for access. The STA must be shallow, with burial depth of the chambers not to exceed 2-feet below native grade. COMPONENT SPECIFICATIONS The component manufacturers are typícal of applications used by contractors and engineers in this area GBO lnc. must approve alternative components prior to installation of the OWïS. Requests must be submitted, in writing, to our off¡ce for approval prior to installation. Component technical data sheets are available upon request. Construction must be according to Garfield County On-Site Wastewater Treatment System Regulations, the OWTS Permit provided by Garfield County Building Department, and this design. INSTALLATION CONTRACTOR CBO lnc. 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 ofüce is expected throughout the installation. INSTALLATION OBSERVATIONS CBO lnc. 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 lnc. should be notified 48 hours in advance to observe the installation.

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 re$ponsible for maintaining proper vegetation cover. OPERATION INFORMATION AND MAINTENANCE The property owner shall be responsible for the oper:ation and maintenance of each OWTS servicíng the property. The property owner is responsible for maintaining service contracts for manufactured units, alternating STAs, and any other components needing maintenance. Geo-fabrics or plastics should not be used over the STA. No heavy eguipment, machinery, or materials should be placed on the backfilled STA. Machines with tracks (not wheels) should be used during construction of the STA for better weight distribution. Livestock should not graze on the STA. Plumbing fixtures should be checked to en$ure that no additional water is being discharged to O\^nS. For example, a running toilet or leaky faucet can discharge hundreds of gallons of water a day and harm a STA. lf an effluent filter or screen has been installed in the OWTS, we recommend this filter or screen be cleaned annually, or as needed. lf 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 lf 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. Page I LIMITS: The design is based on information subm¡tted. lf soil conditions encountered are different from conditions described in report, CBO lnc. should be notified. AIIOWTS 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 requ¡rements 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 lnc.Reviewed By: (læn[a ûrtbuxg Carla Ostberg, MPH, REHS Romeo A.

Box 1534 Eagle, CO 81631 altitudeseptic@gmail.com www.altitudeseptic.com 07/26/2O2t 277 Jø Court, Glenwood Springs, CO Altitude Septic, LLC was hired to perform a Septic inspection at the above address. There are no records available from the county on th¡s septic system. The current system at the main house has a 1000-gallon plastic septic tank that has risers on the tank to bring access to the surtace. The risers are not sealed and can allow water in or out, the ¡nlet and outlet tees are in place. The tank itself appears to be watertight, we also jetted and used a sewer camera in the outlet to determine that the leach field is hotding water. There is an inspection port at the end of the leach field, and it is holding water. This only further confirms that the leach field is failing. I would recommend replacing this system. The cabin on this property has a S0O-gallon single compartment plastic septic tank, this tank had normal levels and is functioning as it should. There is an outlet tee present, and the tank has risers to the surface. The leach field area shows no signs of failure, there are no inspection ports on this leach field. A new leach field at current prices will run in the 530,000.00 range. lf you have any questions, please give me a call Jason Altitude Septic, LLC 970-47t-L330 Please be aware of the following disclaimer: Altitude Sepfic accepfs no responsibility for the proper operation of this sepfic sysfem.
