Box 885 Silt, Colorado 81652 (cmurillo2353@gmail.com) Project No. 21-7-306 Subject: Certification of Onsite Wastewater Treatment System, Proposed Residence, Tract 20, Antlers Orchard, 152 Rusty Spur Trail, Garfield County, Colorado Dear Chela: A representative of Kumar & Associates observed the installation of the Onsite Wastewater Treatment System (OWTS) for the residence at the subject site as required by the Garfield County Environmental Health Department. Our observations and recommendations are presented in this report. The services are supplemental to Kumar & Associates agreement for professional services to you dated March 29, 2021. We previously designed the OWTS for the residence as submitted in our report dated November 29, 2021, Project No. 21-7-306. The system was designed for three bedrooms. The OWTS was installed by you. We performed our evaluation on October 17, 2023. The OWTS components observed included: sewer line, cleanout, septic tank, effluent line, distribution box and soil treatment area (STA) and the locations of these components. The installation and locations of the system components were verified as shown on Figure 1. Pictures of the OWTS components made during the site visit are included with this report. The distance locations to the septic tank shown on Figure 1 were made by taping. The proposed Tuftite 4-hole distribution box was changed to a Polylok 4-hole distribution box. The change is acceptable to us. It is our opinion that the OWTS was installed in general conformance with the above referenced design, and no shallow confining soil layer exists as we assumed for our original design. The observations and recommendations presented above are based on our site observations and our experience in the area. We make no warranty either express or implied. Alterations to the system or improper backfill and site grading could affect the operation and effectiveness of the OWTS.
