O. Box 543 Glenwood Springs, Colorado 81602 ewags67@gmail.com Project No. 23-7-689 Subject: Certification of Onsite Wastewater Treatment System, Proposed Residence, Lot 2, Piffer Subdivision Exemption, 321 Ram Lane, Garfield County, Colorado Dear Evan: As requested, 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 December 7, 2023. We previously designed the OWTS for the residence as submitted in our report dated March 29, 2024, Project No. 23-7-689. The residence has 3 bedrooms. The system was designed for five bedrooms to allow for future expansion. We performed our as-built evaluation on December 11 and 20, 2024. The OWTS components observed included: septic tank, distribution box, effluent line 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 septic tank was changed from a Valley Precast 1,500-gallon, two -chamber tank to an Infiltrator IM-1530, 1,530-gallon, two-chamber tank. The change is acceptable to us. It is our opinion that the OWTS was installed in general conformance with the above referenced design.
