Farrell, PE. The system is designed to serve a 5 bedroom single family residence. The system consists of a Valley Precast 1,250 gallon, single compartment tank with effluent screen and alarm placed on the outlet, followed by a 2,000 gallon Valley Precast 3-compartment recirculating/dose tank which will send wastewater to two, Advantex AX-20 pods for nitrification using an Orenco PF500512 pump. Nitrified effluent flows to the splitter valve (mode 3B) for recirculation to the 1,250 gallon first tank for denitrification then is dosed using an Orenco PF751012 pump to 960 square feet of soil treatment area (STA). The STA consists of four rows of 20 Infiltrator Quick 4 Plus Standard chambers arranged in a shallow bed for a total of 80 chambers. 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. 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 80 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 more efficient and informed site visit and soil evaluation, a preliminary investigation was conducted the week of October 1st, 2019. 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; this geotechnical investigation has been submitted to Eagle County previously. Results from the HP Geotech report showed that Test Hole A had a topsoil from zero to six inches deep, then a clay layer to three feet, and a gravel-clay layer from three to eight feet deep. Test Hole B had a topsoil from zero to six inches deep, then a clay layer to four feet deep, and a gravel-clay layer from four to eight feet deep. No groundwater was encountered in either test holes. SITE VISIT AND SOIL EVALUATION A site visit and soil evaluation were conducted on June 18, 2020 by Julie Gustavson; Julie has passed the Colorado Professionals in Onsite Wastewater (CPOW) Soils Evaluation Course. 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 is relatively flat with a slight slope from south to north. The dominant vegetation at the proposed OWTS consists of native grasses and trees. 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 six and a half feet deep was consistent with a Soil Type 3, and from six and a half to seven and a half feet deep was river Frost Creek Lot 80 Site and Soil Investigation 10/23/20 2 of 3 rock. At seven and a half feet from the surface ground water started appearing. Similarly, Soil Profile Hole Two had a Soil Type 3 layer to seven and a half feet deep, followed by river rock to eight feet deep, where ground water started appearing. Figures 1 through 4 below show the soil profile holes and corresponding morphology. Therefore, soil type 3 was identified as the soil type. The proposed STA will be a bed with the infiltrative surface three feet below grade. Table 1 – Visual and Tactile Soil Results Profile Hole Depth (ft.)
