2.1 Property lnformation
PhvsicalAddress: 5169 County Road 154, Glenwood Springs, Colorado.
Lesal Description: Section 1 Township:7 Range: 89; TR in Lot g. Account No. R011595, Parcel
239501 1 00098.
Existinq Structures: Presently, there is a one story wood frame structure on site used for retail
space. According to County documents the following information for the structure was obtained.
. The structure has 168 square feet of heated area. The structure has no bedrooms.o The structure has no bathrooms.¡ The structure has one story.
Domestic Water: Provided by an existing well in the western portion of the subject property. The
well is located greater than the minimum setback requirement of 100 feet, Table 7-1 of Reg43.
2.2 Public Health Agency Records
Search of Garfield County's Public Records did not reveal existing documents to indicate an
existing OWTS is permitted for the subject property.
2.3 Topography
Existing topography in the vicinity of the OWTS slopes from northeast towards the southwest at
grades of between 2.0 lo 4.0 percent. Grades in the northwest towards southeast are flat and
continuous, not broken by irregularities in the ground surface. Grades are not proposed to change
under proposed conditions"
2.4 Soil Data
According to the Web Soil Survey for the Natural Resources Conservation Service (NRCS), soils
associated with this subject property are classified as map unit 28-, Dahlquist-Southace complex.
Page 5 of l3
Dahlquist-Southace has grades of between 12 to 25 percent, which does not agree with field
observation.
Dahlquist-Southace also has a very limited rating for septic tank absorption fields due to large
slopes, filtering capacity and slopes. However, plotting of percentages of clay, sand and silt given
for this soil unit on the USDA Textural Triangle indicates the soils would classify as soil type 2 or
2A. Soils having a classification type of 3 or 3A are very suitable for absorption fields, having
long term application rates (LTAR) of 0.35 and 0.3 gallons per day per square foot of area (gpd/ft2),
respectively.

A detailed soil investigation to determine the depth to the limiting layer, if any, and properly classify
the soil type was conducted on August 9,2021. Visual evaluation of five soil profile test pits were
conducted in the field and samples collected from each test pit. The samples were taken to SGM's
Office to classify the soil type that will receive the effluent waste using the soil texture by feel method.
Page 6 of 13
Test pits were excavated adjacent to the proposed location for the STA, see sheet C9 for locations.
Visual evaluation of all test pits was conducted under adequate light conditions, with the soil being in
an unfrozen state.
3.1 Visual Evaluation
The Client's excavator excavated five soil profile test pits, TP-1 through TP-s, with SGM personnel
being on site. All test pits were excavated to an approximate depth of 5 to 8 feet, with no
groundwater nor bedrock being encountered. Observations of the excavated test pits show:
¡ Test pits TP-1 through TP-3 were excavated to a depth of 96 inches, TP-4 to a depth of
84 inches and TP-5 to a depth of 60 inches.. Test pits TP-1 through TP-4 had roadway gravels between the depths of 0 inches to 18
inches.. Test pit TP-5 had topsoil between the depths of 0 inches to 12 inches.
. Test pits TP-1 through TP-3 exhibited soils with sandy clay texture, prismatic soil
structure shape, moderate soil structure grade and soil consistence of friable from
between 12 inches to 96 inches.. Gravel became more prominent in test pits TP-2 and TP-3 at a depth of 60 inches.
o Test pits TP-4 and TP-S exhibited soils having sand varying from a fine to coarse texture,
granular soil structure shape, weak soil structure grade and soil consistence of loose
from between 12 inches to 84 inches.. Excavation of test pits TP-4 and TP-5 were terminated prior to reaching 8 feet due to the
observation these soils were a limiting layer of type "R" soils.
Soil observation logs and photos can be found in the Appendix
All measurements are from ground surface
3.2 Tactile Evaluation
SGM conducted a Soil Texture by Feel test on soil samples collected from test pits TP-3 and TP-
5 per CPOW's methodology. Tests were not performed on samples from TP-1 and TP-2 as the
samples were identical to the sample tested from TP-3. The sample from TP-4 was identical to
the sample tested for TP-5.
Gravels were present in sample TP-3, but were less than 35 percent rock, therefore Table 10-1 ,
Section 43.10 of Reg43 was used to determine soiltype and the applicable long term application
rate (LTAR) for this soil type.
Gravels were present in sample TP-S and was greater than 35 percent rock, therefore Table 10-
1A was used to determine the soil type and the applicable LTAR for this soil type.
Page 7 of l3
Results of the soil texture by feel tests are shown in the following table.

Results shown in the above table indicate a USDA soil classification of Sandy Clay Loam, type 3
or 3A for the soils sampled from TP-3; for the soils sampled from TP-S the indication is the soil is
sand, type 1 and since the volume of gravel was greater than 35 percent the soil type is R-0.
To determine the proper soil type, 3 or 3A for the soils sampled from TP-3, the USDA soil structure
type and grade were used. The following Table shows the soil's USDA structure type and grade
determined for the sample.

According to Table 10-1 , section 43.10 of Reg43, both soil types 3 and 3A can have a prismatic
structure type, but only soil type 3 can have a moderate soil structure grade. As such, the soil
to receive the effluent waste is classified as soil type 3, having a LTAR of 0.35 gpdfft'zfor receiving
treatment level 1 (TL1) effluent.
The USDA soil classification based on NRCS data for clay, sand and silt percentages in
subsection 2.4 above supports this conclusion.
SGM's worksheets for the Soil Observation Logs, Soil Texture by Feel and STA LTAR by Soil
Texture, Soil Structure and Treatment Level can be found in the Appendix.

The STA shall be installed as shown on sheet C9
1. One bed with 38 infiltrators.
2. Bed shall be no wider lhan 12 feet, four infiltrators placed side-by-side.
3. Bed length shall be as shown on C9 but shall not exceed 60 feet.
4. The infiltrative surface shall be no greater than 3-feet from the surface.
5. Bed floors shall be level.
6. Chambers shall be placed per the manufacturer's directions.
The STA configuration shown on sheet C9 may be modified or changed in the field if guidelines 2
through 7 are maintained and setbacks in section 2.5 can be met. Other setbacks per Table 7-1 of
Reg43 may be required, so review of Table 7-1 should be completed prior to relocating a STA bed.
ln addition, the Engineer should be consulted prior to relocating the STA.
The STA shall have a final soil cover as described on Sheet C10. This may mean that the STA cover
will need to be 16-inches +/- when initially placed to allow for settlement over the freeze-thaw of a
winter season. The surface of the STA shall be seeded after installation of the system. A native,
upland seed mix should be used. These mixes do not require irrigation and develop a growth 10 to
15 inches high. No automatic sprinkler system shall be installed over the STA. Vehicular traffic and
livestock snãll Oe kept off of the STA. No landscaping, impervious surfaces or plastic sheeting can
be installed over the STA, which will reduce its performance.

The installation of the OWTS shall be observed by the design engineer. A final dosing observation
will be required prior to placing the OWTS into service. Our office shall be called at 970-945-1004 to
observe the installation at least three days in advance.

The goal of an operation and maintenance schedule is to observe the operation, and perform minor
maintenance to the onsite wastewater system to allow for proper, long-term functioning of the system.
Septic tanks: The scum and sludge accumulation in the septic tanks shall be monitored yearly. Once
the cumulative scum or sludge thickness reaches 25o/o of the tank depth, the entire tank shall be
pumped. A pumping frequency of 1 to 3 years is expected at design flows. An alternative is a regular
pumping frequency of every 2 years.
Filter and Effluent Pumnino Svsfern:The effluent filter at the septic tank discharge shall be cleaned
(hosed off) at the time of pumping or as needed. The etfluent pumps shall be checked semi-annually
to ensure pumps are functioning properly. lf the alarm sounds, the pumps and floats shall be checked
and/or serviced immediately.
General: System users must realize that an on-site wastewater treatment system is different from
public sewer service. There are daily considerations, such as not putting plastic or other non-
biodegradable material into the system. Water use shall be monitored so that toilets are not allowed
to leak when seals malfunction. Allowing fixtures to flow continuously to prevent water lines from
freezing is not acceptable. Although the proposed system can accommodate variable flows,
spreading water use over several hours and eliminating peak flows is recommended. To illustrate
the point, a malfunctioning toilet can discharge in excess of 1,000 GPD. Excessive daily loading
could flood and irreparably harm the OWTS.
SGM recommends against installation of a water softener. The chemical and hydraulic loading from
the backwash of a water softener would be damaging to the OWTS, so if a softener is installed, a
separate drywell shall be constructed for the backwash waste. No landscaping or plastic can be used
over the STA, which would reduce the performance of the STA. The design of the OWTS is based
on the treatment of domestic sewage only. Swimming pool or spa water is not to be discharged into
the OWTS. The proposed OWTS design is based on the regulatory flows noted in the attached
calculations. lncreased flows may hydraulically or organically overload the OWTS, causing
premature failure.

Our investigation, layout, design, and recommendations are based on data provided by others. The
contents of this letter shall not serve as the basis for any third party engineering design. lf conditions
that are considerably different from those described in this report are encountered, SGM shall be
called to evaluate the conditions. lf the proposed construction is changed, SGM shall be notified to
evaluate the effect of the changes on the OWTS. All construction shall be in accordance with the
Garfield County OWTS regulations. Pipe type and size, burial requirements, septic tank construction,
and other specifications, which are not depicted in our report, shall conform to the requirements of
the County OWTS regulations. The installer of the system shall be acceptable by the County's
Environmental Health Department and shall have demonstrated knowledge of the County's OWTS
regulations and requirements.

Septic TankAbsorption Fields-Aspen-Gypsum Area, Colorado, Parts of Eagle, Garfield, and
Pitkin Counties
GALLEGOS VENTURES, INC
Description
Septic tank absorption fields are areas in which effluent from a septic tank is
distributed into the soil through subsurface tiles or perforated pipe. Only that part
of the soil between depths of 24 and 60 inches is evaluated. The ratings are
based on the soil properties that affect absorption of the effluent, construction
and maintenance of the system, and public health. Saturated hydraulic
conductivity (Ksat), depth to a water table, ponding, depth to bedrock or a
cemented pan, and flooding affect absorption of the effluent. Stones and
boulders, ice, and bedrock or a cemented pan interfere with installation.
Subsidence interferes with installation and maintenance. Excessive slope may
cause lateral seepage and surfacing of the effluent in downslope areas.
Some soils are underlain by loose sand and gravel or fractured bedrock at a
depth of less than 4 feet below the distribution lines. ln these soils the absorption
field may not adequately filter the effluent, particularly when the system is new.
As a result, the ground water may become contaminated.
The ratings are both verbal and numerical. Rating class terms indicate the extent
to which the soils are limited by all of the soil features that affect the specified
use. "Not limited" indicates that the soil has features that are very favorable for
the specified use. Good performance and very low maintenance can be
expected. "Somewhat limited" indicates that the soil has features that are
moderately favorable for the specified use. The limitations can be overcome or
minimized by special planning, design, or installation. Fair performance and
moderate maintenance can be expected. "Very limited" indicates that the soil has
one or more features that are unfavorable for the specified use. The limitations
generally cannot be overcome without major soil reclamation, special design, or
expensive installation procedures. Poor performance and high maintenance can
be expected.
Numerical ratings indicate the severity of individual limitations. The ratings are
shown as decimal fractions ranging from 0.01 to 1.00. They indicate gradations
between the point at which a soil feature has the greatest negative impact on the
use (1.00) and the point at which the soil feature is not a limitation (0.00).
The map unit components listed for each map unit in the accompanying
Summary by Map Unit table in Web Soil Survey or the Aggregation Report in Soil
Data Viewer are determined by the aggregation method chosen. An aggregated
rating class is shown for each map unit. The components listed for each map unit
are only those that have the same rating class as listed for the map unit. The
percent composition of each component in a particular map unit is presented to
help the user better understand the percentage of each map unit that has the
rating presented.
Other components with different ratings may be present in each map unit. The
ratings for all components, regardless of the map unit aggregated rating, can be
viewed by generating the equivalent report from the Soil Reports tab in Web Soil
Survey or from the Soil Data Mart site. Onsite investigation may be needed to
validate these interpretations and to confirm the identity of the soil on a given
site.

Rating Options
Aggregation Method: Dominant Condition
Aggregation is the process by which a set of component attribute values is
reduced to a single value that represents the map unit as a whole.
A map unit is typically composed of one or more "components". A component is
either some type of soil or some nonsoil entity, e.9., rock outcrop. For the
attribute being aggregated, the first step of the aggregation process is to derive
one attribute value for each of a map unit's components. From this set of
component attributes, the next step of the aggregation process derives a single
value that represents the map unit as a whole. Once a single value for each map
unit is derived, a thematic map for soil map units can be rendered. Aggregation
must be done because, on any soil map, map units are delineated but
components are not.
For each of a map unit's components, a corresponding percent composition is
recorded. A percent composition of 60 indicates that the corresponding
component typically makes up approximately 60% of the map unit. Percent
composition is a criticalfactor in some, but not all, aggregation methods.
The aggregation method "Dominant Condition" first groups like attribute values
for the components in a map unit. For each group, percent composition is set to
the sum of the percent composition of all components participating in that group.
These groups now represent "conditions" rather than components. The attribute
value associated with the group with the highest cumulative percent composition
is returned. lf more than one group shares the highest cumulative percent
composition, the corresponding "tie-break" rule determines which value should
be returned. The "tie-break" rule indicates whether the lower or higher group
value should be returned in the case of a percent composition tie. The result
returned by this aggregation method represents the dominant condition
throughout the map unit only when no tie has occurred.
Component Percent Cutoff: None Specified
Components whose percent composition is below the cutoff value will not be
considered. lf no cutoff value is specified, all components in the database will be
considered. The data for some contrasting soils of minor extent may not be in the
database, and therefore are not considered.
Tie-break Rule; Higher
The tie-break rule indicates which value should be selected from a set of multiple
candidate values, or which value should be selected in the event of a percent
composition tie.
