RE: Final approval of septic permit OWTS-10-15-13607; Tax parcel #210925302004;
Property location: 598 Frost Creek Dr., Eagle area
Mr. Rinn,
This letter is to inform you that the above-referenced septic permit has been inspected and
finalized. This permit was approved and sized for a total capacity for 4 bedrooms. Maintenance
of your septic system will be scheduled by the Frost Creek maintenance team. The system is
connected and can be monitored remotely as required in the PUD. JVA will be working with
Frost Creek on the management of this more advanced remote monitoring technology.
Be aware that changes in the use of your property or alterations of your building may
require commensurate changes to, or relocation of, your septic system. Landscape features,
trees with tap roots, irrigation systems and parking areas above the drain field can cause
premature system failure. It is equally important that you notice and immediately repair
dripping faucets and hissing toilets as this will certainly cause the system to fail. By
following a few simple guidelines, like avoiding grease or other additives down the drain
your system has been designed to last for many years.
If you have any questions regarding this information, please contact us at (970) 328-8755 and
reference the OWTS septic permit number.
Sincerely,
Terri Vroman

RE: Soil and Site Evaluation
Lots 63, Frost Creek Filing No. 1
0598 Frost Creek Road
Eagle County, Colorado
Project NO. 15-3055
On September 17 and 18, 2015, we met with you at your property on Lots 63, Frost Creek
Filing No. 1, 0598 Frost Creek Road, Eagle County, Colorado. The purpose of our site visits was
to observe and test the area designated on the site plan that meets the criteria of OWTS #43, for a
septic system for the proposed Rinn Residence. Lot 63 is a 4.151 acre parcel of land at 0598
Frost Creek Road, off of Brush Creek Road, approximately 5.4 miles south from the intersection
of Brush Creek Road and Sylvan Lake Road, in Eagle, Eagle County, Colorado. The septic
system will have a secondary treatment in order to meet the Frost Creek PUD regulations for
nutrient removal.
!Preliminary Investigation
G Address: 0598 Frost Creek Road, southeast from the Town Of Eagle,
Eagle County, Colorado
G Legal Description: Lots 63, Frost Creek & Salt Creek PUD, Filing No. 1,
Eagle County, Colorado
G Existing Structures: There was an old shack on the southwest corner of
the lot.
G Location of existing and proposed wells on property: Water is provided
by the Town of Eagle Water Department.
G ECEHD records: There are no septic systems on Lot 63.
G Topography: The topography of the property is rolling. Within the
proposed leachfield area the topography was moderate, sloping gently to
the east. The leachfield will be located on the lower east portion of the lot,
in the back yard of the proposed residence.
G Soil Data: Two profile holes were excavated and observed. Profile hole
number one had about 18 inches of topsoil, over 14 inches of light brown,
silty sand with angular rock fragments over about 16 inches layer of
orange-brown, sandstone rock fragments over four feet of brown-orange,
silty clayey sand. The soil was moist near the bottom, but no free ground
water was encountered. The soil encountered in the profile hole No. 2
consisted of about a foot of Topsoil over about 20 inches of blocky clay

over 4.5 feet of light, reddish-brown, silty-sandy gravel with subround to
subangular cobbles and boulders. After 5 feet, the moisture increased and
the soil profile had grayish-orange discoloration. There was no ground
water or bedrock observed in the profile hole at the time of the excavation.
G Location of applicable setbacks in Table 7-1: The proposed septic tank is
about 28 feet away from the house, about 35 feet away from the leachfield.
The leachfield is at least 70 feet away from the house, and over 100 feet
away from the closest property lines.
!Reconnaissance
G Landscape position: The proposed leachfield site will be located in the
back yard, on a linear slope, along the contours.
G Topography: The topography of the proposed leachfield site is moderate
and the trenches will run along the contours.
G Vegetation: The vegetation of the proposed leachfield site consisted of
wild grass.
G Natural and cultural features: The natural topography of the site is
moderate with a gentle slope to the east. A portion of 150 feet wide
drainage easement runs along the south and east property lines of the lot.
Also, there is 50-foot drainage easement at the southwest corner of the lot,
and an old irrigation ditch transverse the lot from about the middle south
toward the northwest lot corner.
G Current and historic land use: Based on the records available, the
property seems to have been used as a ranch by an early settler, W.E.
Frost from the early 1880's. From 1973 the land had been developed into
the residential subdivision Adam’s Rib Ranch with a golf course. Most
recently, in March of 2015 the property had been repurchased and
renamed to Frost Creek Ranch. The use remains as a residential
subdivision with a golf course.
!Detailed Soil Investigation
G Visual and tactile evaluation of two or more soil profile test pit

Re: Impact of Frost Creek PUD on water resources in Brush Creek Valley, upstream
from Town of Eagle, CO
Since 2003, Wright Water Engineers (WWE) has overseen the Water Quality Management Plan for
the Frost Creek PUD (previously known as Adam’s Rib Ranch). Our work has been conducted for
the owners of the PUD, working closely with the Eagle County Health Department. As part of this
effort, WWE has monitored the surface water in Frost Creek, Salt Creek, and Brush Creek as well as
the groundwater throughout the planned development. This had included water quality monitoring
during both construction and post-construction conditions, including biological monitoring every
three years. Limited wetland monitoring has also been conducted. We have been asked to provide
an overall finding regarding the impacts to date of the Frost Creek PUD on water resources in the
Brush Creek Valley. Based on all of the data that have been collected since 2003, and considering the
written agreement that was reached between the Eagle County Health Department and the previous
owner of Adam’s Rib Ranch regarding water quality monitoring and mitigation, there have not been
significant impacts (ie. impacts which exceeded the “trigger limits” established in the agreement) to
the surface waters that have been monitored.
Surface water trigger limits for the Frost Creek PUD were established in 2005 using historical water
quality data from the 1970s through the 1990s. Surface water trigger limits were established in April
2012 for the Salt Creek Equestrian Center Parcel using five years of background data. Surface water
trigger limits were established for Total Suspended Solids (TSS), Total Dissolved Solids (TDS), and
Total Phosphorus (TP). The last four years of sample results are summarized below to provide the
basis for our finding that the Frost Creek PUD has not caused significant adverse impacts to water
resources.
During the 2012 sampling season there was one exceedance of TP in a surface water sample from
Salt Creek during the April sampling event. This exceedance was seen at the upstream (background)
sampling location and not at the location downstream of the PUD. Consequently, this exceedance
represented background water quality data. In both the August 2012 and September 2012 sampling
events, the Salt Creek locations exceeded trigger limits for TSS. These exceedances were attributed
to a newly constructed beaver dam upstream in Salt Creek and not attributed to impacts by the Salt
Creek Equestrian Center Parcel or the Frost Creek PUD.
November 2, 2015
Page 2
During the 2013 sampling season no trigger limits were exceeded.
During the 2014 sampling season there was one exceedance of TP in a surface water sample from
Frost Creek during the October sampling event. This exceedance was not consistent with a long term
trend of non-exceedance, one of the triggers in the original agreement.
The most recent 2015 sampling season results are summarized by excerpts from the June 2, 2015
letter to Ray Merry and Matt Shoulders from WWE.
“For both sampling locations of Brush Creek within the Salt Creek Equestrian Center Parcel
(SWBC-3 and SWBC-4), the trigger limits for TSS and TP were exceeded. These
exceedances of the trigger limits were likely caused by the rain event that occurred before and
during the sampling. This sampling event is not consistent with a long term trend but rather
shows a sudden increase in the TP and TSS concentrations found at SWBC-3 and SWBC-4.
These locations will be monitored closely in the future to determine if there is an increasing
trend.” [note: SWBC-3 is a background sampling point.]
“Based on the updated surface water trigger limits for the Salt Creek Equestrian Center Parcel,
the levels of TP at both SWSC-1 and SWSC-2 exceed the trigger limits shown in Table 4.
The TSS level at SWSC-1 exceeds the trigger limit shown in Table 4 as well. These
exceedances are not consistent with a long term trend but rather show a sudden increase in the
TP and TSS concentrations found at Salt Creek within the Salt Creek Equestrian Center
Parcel. These locations will be monitored closely in the future to determine if there is an
increasing trend.” [note: SWSC-1 is a background sampling point.]
On the basis of the data presented above from 2012 to 2015, the Frost Creek PUD has not significantly
adversely affected surface water quality.
Sincerely,
WRIGHT WATER ENGINEERS, INC.

Orenco Systems Incorporated
814 Airway Ave.
Sutherlin, OR 97479
Subject: Orenco, Advantex Series, Proprietary Treatment Product - Acceptance
For Use in Colorado On-site Wastewater Treatment Systems
Dear Mr. Soulia:
Pursuant to section 43.13 of the On-site Wastewater Treatment System Regulation 5 CCR 1002-43
(Regulation 43), the Water Quality Control Division (Division) has reviewed drawings and
specifications received between October 6, 2014 and January 12, 2015 for the Advantex proprietary
treatment technology products listed below.
The Advantex treatment technology is accepted as a higher level treatment system for use as a
component of an on-site wastewater treatment system (OWTS) subject to the design criteria in Table
1 below. This acceptance is not intended as an endorsement or third-party certification of the
technology.
This acceptance addresses the following product models:
Orenco, Advantex AX-20 for treatment level TL3N with flows up to 500 gpd.
Orenco, Advantex AX-20RT for treatment level TL3N with flows up to 500 gpd.
Orenco, Advantex AX-25RT for treatment level TL3N with flows up to 625 gpd.
Orenco, Advantex AX-100 for treatment level TL3N with flows up to 2,000 gpd.
This acceptance applies only to OWTS with design capacity less than or equal to 2,000 gallons per
day (gpd). Review and approval for the design of any OWTS proposing to use this technology will
be reviewed by the local public health agency. As individual local public health agency regulations
may be more stringent than Regulation 43, the Division cannot ensure the acceptance of a treatment
technology within any given jurisdiction.
Any modifications to the physical attributes or characteristics of this treatment technology must be
submitted to this office for review and acceptance by the Division prior to sale in Colorado. The
Division will review modifications, any additional third party verification reports and issue a revised
acceptance letter, or denial, as appropriate.
Joe Soulia, Orenco Systems Inc. March 26, 2015
On-site Wastewater Treatment System Treatment Technology Acceptance Page 2 of 4
Table 1. Design Criteria for Orenco Systems Inc., Advantex series models listed above:
Design Criteria
1. A septic tank consistent with section 43.9(A) and 43.9(B) and an effluent screen consistent
with section 43.3(44) and 43.9(I) must precede the treatment unit. Surge volume may be
required for some applications based on manufacturer recommendations. Pretreatment for
non-residential kitchens must include adequate separate grease separator tank(s) prior to
the primary septic tank(s) as required in section 43.9(J) of Regulation 43.
2. Mode configuration requirements:
a. In order to attain TL2, TL2N or TL3 effluent, the design of the treatment system may
be configured in “Mode-1” or “Mode-3”. This will ensure the required BOD, TSS and
TN reductions. Mode 1 is defined as recirculating all of the filtrate to the secondary
chamber of the processing tank.
b. The design of the treatment system for TL3N must be configured in “Mode-3” in
order to obtain the required nitrogen reduction for this treatment level. Mode 3 is
defined as recirculating all, or a portion, of the filtrate to the primary chamber of
the processing tank.
3. Cold weather considerations, general:
a. All units must incorporate 1-inch insulation attached to the bottom of all lids and
risers covers integral to the treatment unit. Insulating around the process tanks,
risers, and other components will be at the discretion of the design engineer.
b. For installations in areas where snow accumulates each winter, the air vent must be
extended to ensure it terminates above the peak snow level.
4. Cold weather considerations for TL2N, TL3 and TL3N:
a. As per data supplied by Orenco Systems Inc., treatment systems that integrate
“passive” ventilation do not require a warm air source for the treatment pod. This
configuration would be typical of a single family residential treatment system.
b. Systems that integrate “active” air ventilation will require a temperature controlled
air source to ensure that the temperature of the filtrate remains above 50º F. This
configuration would be typical of a commercial treatment system with an AX-100
treatment unit.
5. Timer settings for dosing the treatment unit:
a. Timed-dosing to the treatment unit is required. The initial timer settings should be
established based on the expected average daily flow and a 4:1 filter recirculation
ratio.
b. A residual pressure of 3 to 6 feet (5 feet desired) within the treatment unit is used to
determine the initial timed-dose settings.
c. AX-20 and AX-20RT: The “on” time should remain constant at 45 seconds per dose.
The “off” time should be adjusted depending on the average daily flows. See the
Orenco Systems design manual for further specifications.
d. AX-25RT: The “on” time should remain constant at 60 seconds per dose. The “off”
time should be adjusted depending on the average daily flows. See the Orenco
Systems design manual for further specifications.
6. Design flow shall be for maximum occupancy. Design flow for single-family residential
designs may vary based on the regulations adopted by the local board of health for each
specific location. Design flow values and strengths for multi-family and commercial systems
shall be consistent with section 43.6(A)(4). Therefore, all design criteria in this acceptance
are based on total gallons per day and the assumption of residential strength wastewater.
Joe Soulia, Orenco Systems Inc. March 26, 2015
On-site Wastewater Treatment System Treatment Technology Acceptance Page 3 of 4
7. The design must include pressure dosed distribution of effluent. Reductions in soil treatment
area size or separation distances shall be as described in section 43.10(C)(4) of Regulation
43.
8. The designated higher level treatment rating is identified for each model on page 1. Use in
higher level treatment applications requires system be designed by a Colorado Licensed
Professional Engineer. The accepted treatment product may also be used for applications
requiring less than the approved treatment level of the product. Reductions in soil
treatment area size or separation distances based on higher level treatment may not be
applied unless the local public health agency has a maintenance oversight program in place
as described in section 43.14.D of Regulation 43. In locations where the local public health
agency has not adopted a maintenance oversight program, the treatment system may be
used but only with soil treatment area size and separation distances consistent with
treatment level TL1 requirements.
9. In addition to these design criteria, other provisions of Regulation 43 and local regulations
also apply to a specific design as well as good OWTS design practice. The Division does not
approve manufacturer design manuals. Manufacturer provisions shall not be applicable if
those provisions are not consistent with Regulation 43, these design criteria, and the
regulations adopted by the local board of health for the design location. Local public health
agencies will review proposed designs to confirm consistency with Regulation 43, these
design criteria, the local board of health regulations adopted pursuant to Regulation 43, and
good OWTS design practice.
10. Monitoring of the system may be required by the regulations adopted by the local board of
health for the design location.
11. The treatment technology is not intended for industrial sources of wastewater. The
treatment technology is intended to receive domestic wastewater with TL1 concentrations
(see Table 6-3 in Regulation 43) exiting the septic tank. Wastewater with higher
concentrations will require verification of the products ability to treat the wastewater and
appropriate modifications or pretreatment.
12. Design shall provide access for maintenance and repair. As per the requirements of
Regulation 43, septic tanks and all treatment components, other than the soil treatment
area, shall be equipped with access manholes and risers that extend to or above final grade.
All risers and lids shall be watertight and secure.
Additional Operation and Maintenance Criteria
1. Design shall include an Operation and Maintenance (O&M) Manual to be provided for all
installations. Individual operation plans shall include scheduled inspections, assessments,
and maintenance of the treatment. This plan for scheduled inspections and assessments
should include a routine inspection as described in section 43.14(D)(4)(b) unless the local
regulations require more frequent inspections.
The owner of the OWTS is responsible for arranging proper design, operation, and maintenance of
the facility to achieve the desired treatment level.
