Permitted Construction / Details:
Install the OWTS exactly as depicted in the JVA, Inc. design stamped, signed and dated March 31, 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 3 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 (mode 3B) for recirculation to the 1,250 gallon first tank for denitrification then is dosed using an
Orenco PF 751012 pump to 1715 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. 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.

RE: Frost Creek - Onsite Wastewater Treatment System Design – Lot 8, Eagle County, CO
Dear Claire:
JVA Inc. (JVA) has prepared a design of an onsite wastewater treatment system (OWTS) to
serve Lot 8 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

RE: Frost Creek Lot 8 – Site and Soil Investigation Report for an Onsite Wastewater
Treatment System (OWTS)
JVA Job No. 1037.7e
Dear Claire:
Enclosed in this report are the results of the site and soil evaluation for Lot 8’s proposed OWTS
located in Frost Creek, Colorado. 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 September 16, 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. The HP Geotech report shows there were no test holes dug in this area, however the
results from a nearby test hole show that it consisted of a topsoil followed by a sandy clay layer
from 0.5 to 4 feet deep and a rocky, sandy clay from 4 to 8 feet deep. No groundwater was
encountered in either test holes.
SITE VISIT AND SOIL EVALUATION
A site visit and soil evaluation were conducted on September 30th, 2019 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 in a small valley that slopes gently from southwest to northeast. The
dominant vegetation at the proposed OWTS consists of native grasses and sage. 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 approximate locations identified in the
Permit Documents. As seen in Table 1 below, soil morphology for each soil profile hole from the
surface up to three feet deep was consistent with a Soil Type 3, and from three to eight feet deep
with a Soil Type 3 with R-1, Option 1. Figures 1 through 4 below show the soil profile holes and

corresponding morphology. No redoximorphic features, indicating seasonally high groundwater,
were observed in either profile hole. Therefore, Soil Type R-1, Option 1 was identified as the soil
type; the LTAR of soil type 3 treatment level 1 will be used. The proposed STA will be a bed with
the existing ground as the infiltrative surface.

RE: Onsite Wastewater Treatment System Final Certification – 60 Squires Lane, Frost Creek
Lot 8
Dear Claire:
The Onsite Wastewater Treatment System (OWTS) covered under Eagle County Permit No.
OWTS-018628-2020 was installed by Defina Construction for 60 Squires Ln and is ready for
final certification from Eagle County Environmental Health. This letter certifies that the
construction of the OWTS was completed as per the approved design plan. The final record
drawings from JVA, three-year maintenance contract, and construction photographs are provided
as attachments.
As part of the final approval process JVA ensured that start-up was completed by the
