Box 179 Eagle, CO 81631 Reference: Rusty & Lori Estes Residence (Permit # 2245-02) 2432 Cooley Mesa Road P.O. Box 89, Gypsum, CO 81637 Dear Ms. Fawcett: 876 9W esa give T.O.B. 3644 Eagfe, CO 81631 970-328-0876 Please accept this letter as my Final Certification Letter verifying that the referenced ISDS system was installed under my direction and approval and meets the full intent, capacity and safeguards of the original design. The change of the configuration of the infiltration chambers (as -built previously submitted) is not deemed to reduce or affect infiltration performance. In addition, the inlet and outlet pipes from the septic tank were exposed and grouted with non -shrink mortar by the owner and deemed to be acceptable (pictures previously submitted). Those connections have a built-in waterproof gasket on the tank for additional sealing. Finally, the vertical tank risers were installed with corrugated High Density Polyethylene Pipe (HDPE) with appropriate lid adapters at the top (pictures recently provided by owner). This application of HDPE pipe meets all specifications of AASHTO and ASTM for substitution with concrete pipe (risers) underground. In addition, the HDPE pipe is considered superior to concrete in aspects of water tightness, immune to galvanic and electrochemical effects, resistance to chemical attack and corrosion, and unaffected by soils or effluents with a ph range from 1 to 14. Should you need additional information or clarification, please don't hesitate to call me. incerely, Vern L. Brock, P.E.
