Farrell, PE. The OWTS is designed with capacity to serve a 5 bedroom residence. The system consists of a Valley Precast 1,250 gallon, single compartment tank with effluent filter and high water alarm placed on the outlet tee, followed by a 2,000 gallon Valley Precast three-compartment recirculating/dose tank which will send wastewater to two, Orenco Advantex Series AX 20 pods for nitrification using an Orenco PF 5005 pump. Nitrified effluent flows to the splitter valve for recirculation to the 1,250 gallon first tank for denitrification then is dosed using an Orenco PF 5005 pump to automatic distribution valve that will alternation doses between two shallow beds each consisting of four rows of 21 Infiltrator Quick 4 Plus Standard chambers for a total of 168 Infiltrator chambers, for a total of 2,016 square feet of soil treatment area via. Distribution lateral details, along with orifice size, spacing and orientation are on the design drawing. The contractor must verify that all electrical components and inspections are covered under the electrical permit associated with the Orenco Vericom control panel (Model VCOM-AX20B2) 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, including configuration in mode 3 for treatment level 3N. 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. 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 dwelling.

(JVA) has prepared a design of an onsite wastewater treatment system (OWTS) to serve Lot 45 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 2019 annual Water Quality Monitoring Report prepared by Wright Water Engineers documents exceedances of the 85th percentile background concentrations during sampling events in 2019. The report states the following ‘The trends of water quality parameters seen throughout the sampling of groundwater and surface water at the Frost Creek PUD have not reflected a marked upward increase in concentrations of the sampled parameters. As more homes are constructed on the Frost Creek PUD during 2020, the surface water and groundwater sampling location will continue to be monitored’ 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 a site visit and soil evaluation, a preliminary investigation was conducted the week of August 27, 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. Test holes were not investigated directly on Lot 45, however the current location of Lot 45 falls between Lot 28 and Lot 29 as they were identified in the HP Geotech report. Results from the HP Geotech report for Lot 28 showed that Test Hole A had a topsoil from zero to six inches deep, then a clay layer to eight feet deep. Test Hole B had a topsoil from zero to six inches deep, then a clay layer to eight feet deep. No groundwater was encountered in either test hole. Lot 29 showed that Test Hole A had a topsoil from zero to six inches deep, then a clay layer to eight feet deep. Test Hole B had a topsoil from zero to six inches deep, then a clay layer to eight feet deep. No groundwater was encountered in either test hole. SITE VISIT AND SOIL EVALUATION A site visit and soil evaluation were conducted on August 27, 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 south to north. 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 five feet deep was consistent with a Soil Type 4, and from Frost Creek Lot 45 Site and Soil Investigation 11/9/20 2 of 3 five to eight feet deep was bedrock. Soil morphology for Soil Profile Hole Two from zero to eight feet deep was consistent with a Soil Type 3. 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 4 was identified as the soil type. Table 1 – Visual and Tactile Soil Results Profile Hole Depth (ft.)
