No person shall install, renovate, or repair an OWTS in Eagle County (EC) without a valid EC Systems Contractor License. Any person that conducts a business as a systems contractor without having obtained a valid license section commits a Class 1 petty offense as defined in section 18-1.3-503, C.R.S. Please notify the department when an installer is identified, prior to installation of the OWTS. Install the OWTS exactly as depicted in the JVA, Inc. design stamped, signed and dated April 7, 2020 by Simon A. 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 screen and alarm placed on the outlet, followed by a 2,000 gallon Valley Precast three-compartment recirculating/dose tank which will send wastewater to two, Advantex AX 20 pods for nitrification using an Orenco PF 500512 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 751012 pump to 1728 square feet of soil treatment area via two beds each consisting of four rows of 18 Infiltrator Quick 4 Plus Standard chambers for a total of 144 Infiltrator chambers, set atop two feet of sand filter media that meets a gradiation of prefferred or secondary media as defined in 43.11.C.2. Note: Gradation of the sand media use must be completed within one month prior to the installation and confirmed with the design engineer. If the sand does not conform to secondary or preferred sand media requirements, it cannot be used for the sand treatment media. 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.

Box 179 500 Broadway Eagle, CO 81631 environment@eaglecounty.us April 8, 2020 Ms. Claire Lewandowski, REHS Eagle County Environmental Health 590 Broadway Eagle, CO 81631 RE: Frost Creek - Onsite Wastewater Treatment System Design – Lot 3, Eagle County, CO Dear Claire: JVA Inc. (JVA) has prepared a design of an onsite wastewater treatment system (OWTS) to serve Lot 3 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. 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 and B had a topsoil from zero to six inches deep, then a clay layer to four feet, 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 October 8th, 2019 by James Cochran; James has passed the 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 slopes from west to east, and the dominant vegetation 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. As seen in Table 1 below, Soil Type R-2 was identified as the soil type. 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. The proposed STA will be an unlined sand filter with beds. Frost Creek Lot 3 Site and Soil Investigation 4/8/20 2 of 2 Table 1 – Visual and Tactile Soil Results Profile Hole Depth (ft.)
