Ryan Ivy installed the system. The OWTS design is based on 4-bedrooms. 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 installation included a 1500-gallon, two-compartment Valley Precast concrete septic tank with an Orenco® Biotube Pump Vault and an Orenco® PF3005 pump in the second compartment of the septic tank. The floats were set to dose approximately 50 gallons each pump cycle. There is a filter in the second compartment of the septic tank that must be cleaned annually, or as needed. Risers were installed on the septic tank to bring access to grade. The control panel is located within line of sight of the septic tank. Valley Precast out of Buena Vista performed start up on the pumping system (see enclosed start-up letter dated December 7, 2021). They installed the pumping system and control panel after our visit to the property; therefore, I have approximated the control panel location on our drawing. A 1.5-inch diameter Schedule 40 pump line was installed from the pump to an Orenco® automatic distributing valve (ADV), model 6605. The ADV was placed at a high point in the system in an insulated riser with access from grade. Effluent is pressure dosed through 1.5-inch diameter pipes to five trenches, each with 8 ‘ADS’ ARC chambers, for a total of 40 chambers and 600 square feet of infiltrative area. There was at least 4-feet of undisturbed soil between each trench. Effluent is pressure dosed to 1.5-inch diameter laterals, which must be hung with zip ties from the underside of the chambers. Laterals will have 5/32-inch diameter orifices facing up, with the exception of the first and last holes facing down for drainage. Orifices were drilled 2-feet on center. Each lateral ends in a 90-degree ell facing up with a ball valve for flushing. Valves were placed in a valve box, accessible from grade, for access. Inspection ports were placed at the beginning and end of each trench. Ports may be cut to grade and covered with a valve 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. 3-29-2023 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.

Box 739 Snowmass, CO 81654 Via email: harry@ski.com carla.ostberg@gmail.com Subject: Final Acceptance Letter Lot 8, Coulter Creek Ranch Carbondale, CO 81623 OWTS Permit #: SEPT-6509 December 9, 2021 Harry and Kathryn, On June 1, 2021, we visited the residence at Lot 8 of Coulter Creek Ranch near Carbondale in Garfield County, Colorado to observe the Onsite Wastewater Treatment System (OWTS) installation pursuant to OWTS Permit # SEPT-6509. The contractor had installed the 1,500-gallon septic tank, high-head pump, effluent lines, automatic distributing valve, and five gravelless chamber trenches as designed by CBO, Inc. Cleanouts were installed as required along the sewer line between the house and the septic tank. Risers were installed on the septic tank and automatic distributing valve, as required. Effluent lines and laterals consisted of 1.5-inch diameter Schedule 40 PVC. Laterals were zip-tied to the top of the chambers, with 5/32-inch diameter orifices every three-feet on-center. The first and last orifices on the laterals pointed down to allow for drainage. All other orifices pointed up. Each trench consisted of 8 ARC 36 chambers per trench (40 chambers total, 600 ft2 STA). The effluent line between the tank and the ADV was not installed at the time of our first site visit. On December 8, 2021, we received a letter from the contractor that indicated the effluent pump for the system had been installed, wired, and tested. In our opinion, this system was installed in general conformance with Garfield County OWTS Regulations. No further action or review from Garfield County Environmental Health is required regarding this permit. Thank you, Edward R. “Ted” White, P.E.
