This system was designed to accommodate the maximum daily flows for 3 single-family homes, lots 129, 130 and 132 in Hunters View in the Frost Creek PUD with a maximum total of 12 bedrooms. The OWTS consists of 3 sewer lines, one exiting each residence. The primary treatment for the system consists of two Valley Precast 2,000 gallon, single compartment tanks in series with an effluent filter and alarm placed at the outlet tee of the second tank. The primary treatment tanks are followed by a 2,000 gallon Valley Precast three-compartment recirculating/dose tank which will send wastewater to an Advantex AX-100 pod for nitrification using an Orenco PF500712 pump. Nitrified effluent flows to the splitter valve for recirculation to the first 2,000 gallon tank for denitrification then is dosed using an Orenco PF501512 pump to an automatic distribution valve (ADV), set level at the high point of the system and made accessible at grade. The ADV will alternate dosed effluent to 2,448 square feet of soil treatment area between three beds, each consisting of 4 rows of 17 Infiltrator Quick 4 Plus Standard chambers for a total of 204 chambers. Maintain all elevations and setbacks. NOTE: The contractor must verify that all electrical components and inspections are covered under the electrical permit associated with the Orenco Vericom control panel and pump connections. The alarm must be connected to a separate circuit. Additional pump details are on the design drawing. Advantex systems must conform to the CDPHE technology approval letter dated May 1, 2018. Contact Eagle County Environmental Health and the design engineer well in advance of requesting inspections prior to backfilling any component of the OWTS. The design engineer is responsible for conducting all inspections necessary to certify the installation and assure functionality of the system. Because reductions are taken in the size of the STA, proof of an active operations and maintenance contract must be provided with final certification. System certification, along with photos and a record drawing is required to be submitted to, and approved by, Eagle County Environmental Health prior to the use of the system or occupancy of the dwellings.

October 29, 2021 Ms. Claire Lewandowski, REHS Eagle County Environmental Health 590 Broadway Eagle, CO 81631 RE: Frost Creek - Onsite Wastewater Treatment System Design – Hunters View Lots 129, 130, & 132, Eagle County, CO Dear Claire: JVA Inc. (JVA) has prepared a design of an onsite wastewater treatment system (OWTS) to serve Hunters View Lots 129, 130, & 132 within the Frost Creek PUD. JVA is the designated engineer to process all OWTS permit applications within Frost Creek. JVA has prepared the OWTS design to be in general conformance with OWTS requirements of the PUD. The 2020 annual Water Quality Monitoring Report prepared by Wright Water Engineers documents exceedances of the 85th percentile background concentrations during sampling events in 2020. The report states the following ‘While the concentrations observed in 2020 were high for Total Phosphorus and Total Suspended Solids in surface water, upon evaluation of the pattern of concentrations of each water quality parameter for surface and groundwater at the Frost Creek PUD, there are no evident increasing trends in the concentration of the sampled parameters that were outside of the range of historical values. Therefore, all three components of the trigger limits have not yet been met, and mitigation action is not yet required.’ Sincerely, JVA, INCORPORATED By: _______________________ Simon Farrell, P.E.

This report provides information needed to support the design of an OWTS including: results from the preliminary investigation, the site visit, and the soil evaluation. Design calculations are included in the drawing Permit Set attached. PRELIMINARY INVESTIGATION In preparation for the site visit and soil evaluation, a preliminary investigation was conducted the week of August 17th, 2020. Architectural site plans, aerial imagery, and previous Geotechnical investigations were used for the preliminary investigation. Geotechnical investigations were performed by HP Geotech in October 2002 across Frost Creek for OWTS suitability. Results from the HP Geotech report showed that for the proposed location, Test Hole A had a topsoil from zero to six inches deep, a silt layer to five feet, and a sandy gravel layer to nine feet. Test Hole B had a topsoil from zero to six inches, a silt layer to six feet, and a sandy gravel layer to eight feet. SITE VISIT AND SOIL EVALUATION A site visit and soil evaluation were conducted the week of August 24th, 2020. The purpose of the site visit and soil evaluation was to confirm hypotheses from the preliminary investigation, identify the topography, landscape position, vegetation, and site constraints for the proposed OWTS, and to conduct a visual and tactile soil evaluation of the underlying soils where the proposed soil treatment area (STA) is to be located for both suitability and sizing. The topography of the site slopes from north to south. The dominant vegetation at the proposed OWTS consists of native grasses. Site Constraints are shown in the Permit Documents. For the visual and tactile soil evaluation, two soil profile holes were excavated using a tracked excavator in the locations identified in the Permit Documents. As seen in Table 1 below, soil morphology for Soil Profile Hole One from zero to eight feet was Soil Type 3. Soil Profile Hole Two had Soil Type 3 from zero to eight feet deep. No redoximorphic features, indicating seasonally high ground water, were found in either holes. Figures 1 through 4 below show the soil profile holes and corresponding morphology. Therefore, Soil Type 3 was identified as the soil type.

This letter certifies that the construction of the OWTS was completed as per the approved design plan. The final record drawings from JVA, and construction photographs are provided as attachments. As part of the final approval process JVA observed that start-up was completed by the manufacturer’s representative, and completed a site visit to check all system components. The system is connected and can be monitored remotely as required in the PUD. Sincerely, JVA, INCORPORATED By: ________________________ Simon Farrell, P.E.
