Install the new STA exactly as depicted on the October15,2018 H-P Kumar design packet, signed and stamped by David A.Young, PE on October 16,2018.The system is designed to serve a 4 bedroom residence. Changes to the existing STA will consist of installing two new, shallow trenches closer to the home spaced four feet apart, with15 Infiltrator Quick 4 Plus Standard chambers in the first trench and19 in the second while adding one chamber to the next two trenches in series as shown on the design drawing. A new SDR 35 effluent line will be required to connect the existing septic tank to the first row of Infiltrator chambers with the subsequent trenches connected serially.Additional grading may be required to divert surface drainage away from the STA.The existing trenches that are located within the unused,30' easement may be removed or left in place. NOTE:The 20' and setback from the house to the STA, as well as the edge of the unused,30' easement should be clearly marked prior to installation. Contact Eagle County Environmental Health and the design engineer at least48 hours in advance of requesting inspections.A inspections necessary to certify proper installation must be performed by the design engineer.Final certification, along with a record drawing and photos are required to be submitted to, and approved by, Eagle County Environmental Health prior to the use of the system.

Eagle County Area. Mr. McCarty: This letter is to inform you that the above-referenced, OWTS-10-18-20229 permit, has been inspected and finalized. This OWTS permit was approved and sized to serve the 4 bedrooms, residence. Additional information about the maintenance your septic system needs can be accessed through our website links, provided on the Environmental Health Department’s septic system resource page. Be aware that changes in the use of your property or alterations of your building may require commensurate changes to, or relocation of, your septic system . Landscape features, trees with tap roots, irrigation systems and parking areas above the soil treatment area can cause premature system failure. It is equally important that you notice and immediately repair dripping faucets and hissing toilets as this will certainly cause the system to fail. If you have any questions regarding this information, please contact us at (970) 328-8755 and reference the OWTS septic permit number. Best Regards, Giovanna Harkay.

Grant Street, Apt. 2601 Minneapolis, Minnesota 55404 (jmcca29920@aol.com) Permit No. OWTS-10-18-20229 Project No. 16-7-307.02 Subject: As-Built Evaluation of Modified Onsite Wastewater Treatment System, Existing Residence, Lot 2, Granada Glen, The Divide at Cordillera, 322 Granada Glen Road, Eagle County, Colorado Dear Mr. McCarty: H-P/Kumar observed the modified of the Onsite Wastewater Treatment System (OWTS) for the existing residence at the subject site as required by the Eagle County Environmental Health Department. This report summarizes our observations and recommendations. The services are supplemental to Hepworth-Pawlak Geotechnical (now H-P/Kumar) agreement for professional services to you dated November 10, 2015. Hepworth-Pawlak Geotechnical (now H-P/ Kumar) originally designed the OWTS for the residence and presented the recommendations in a report dated June 27, 2016, Project No. 115 567A. H-P/Kumar submitted a revision to the OWTS design in a letter dated July 19, 2017, Project No. 16-7-307.02. We submitted an As-Built evaluation letter dated August 21, 2017, Project No. 16-7-307.02. At that time the county accepted the system as constructed. It was requested that the portion of the soil treatment area (STA) within the 30 feet vacant utility easement in the lower part of the lot adjacent to Granada Glen Road be relocated. We submitted a modification design of the STA for the OWTS on October 15, 2018, Project No. 16-7-307.02. We performed our As-Built evaluation for the STA modification on November 15, 2018. A. R. Excavating installed the OWTS under Eagle County Permit No. OWTS-10-18-20229. The OWTS components observed included: effluent transport pipe, soil treatment area (STA) and the locations of components. The sewer line and septic tank were previously installed and reported in our August 21, 2017 As-Built letter. The two downhill, southern rows of the existing STA (orange on Fig. 1) were abandoned by cutting and capping the serial connection to them and removing the observation ports. The two new rows of chambers (green on Fig. 1) were placed on the uphill, northern side of the existing STA and connected to the effluent transport line from the septic tank. As designed, an additional chamber was to be placed on each on the existing rows of chambers; however, it was possible in Granad a G l e n ( R . O .

McCarty 500 E. Grant Street, Apt. 2601 Minneapolis, Minnesota 55404 (jmcca29920@aol.com) Permit No. OWTS-7-16-14999 Project No. 16-7-307.02 Subject: Revised STA Layout for OWTS, Existing Residence, Lot 2, Granada Glen, The Divide at Cordillera, 322 Granada Glen Road, Eagle County, Colorado Dear Mr. McCarty: As requested by Don Dotson, we are providing recommendations for revising the soil treatment area (STA) layout for the existing onsite wastewater treatment system (OWTS) at the subject site. This reports provides our recommendations for the new layout of the system. Background: The original design of the OWTS was submitted in a report dated June 27, 2016, Project No. 115 567A by Hepworth-Pawlak Geotechnical (now H-P/Kumar). H-P/Kumar submitted revisions to the design in a letter dated July 19, 2017, Project No. 16-7-307.02. The system was permitted by Eagle County under their Permit No. OWTS-7-16-14999. We provided the OWTS As-Built evaluation for the system in a letter dated August 21, 2017, Project No. 16- 7-307.02. The system is conventional gravity flow to Infiltrators in a trench configuration with serial distribution. The system has been accepted by the County and is functional. We understand that you are requesting the portion of the STA located within the 30 feet vacant utility easement in the lower part of the lot adjacent Granada Glen Road be removed. The system has been designed for four bedrooms as is this current re-design discussed below. Recommendations: A layout of the proposed new STA is provided on the attached Figure 1 with plan and cross section of the STA provided on Figures 2 and 3, respectively. The existing septic tank and sewer line to the tank will remain as installed. Based on site elevations provided by Marcin Engineering, continued gravity flow from the tank to the revised STA is feasible. A new effluent line from the septic tank to the first row (west side) of STA Infiltrators will be needed. The new STA layout will have the effluent gravity flow through the Infiltrator/trenches by serial distribution for dispersal and final treatment. Current State and Eagle County regulations allow the Infiltrator/trenches to have a minimum 4 feet of undisturbed soil between the trenches, rather than the minimum 6 feet separation for the original design. For the STA modifications, the two rows of Infiltrators within the 30 feet easement on the downhill, eastern side of the STA (shown as brown on Figure 1) will be abandoned. Two additional rows of Infiltrators in trenches (shown as green on Figure 1) will be added on the uphill, western side of the STA.
