Our observations and recommendations are presented in this report. The services are supplemental to Kumar & Associates agreement for professional services to Biscayne Trust WGS LLP dated June 5, 2019. We previously designed the OWTS for the cabin as submitted in our report dated August 12, 2019, Project No. 19-7-359.02. The system was designed for four bedrooms. The OWTS was installed under Eagle County Permit Number OWTS-017165-2019 by Highmark Builders. We performed our evaluation on December 11, 2019. At this time, renovation of the cabin was underway. The OWTS components observed included: septic tank, effluent line, distribution box, and soil treatment area (STA) and the locations of these components. The installation and locations of the system components were verified as shown on Figure 1. Pictures of the OWTS components made during the site visit are included with this report. The distance locations to the septic tank shown on Figure 1 were made by taping. The soils exposed in the trench excavations for the STA were sandy loam to loam and similar to those used for the design. The distribution box was changed from the designed Tuf-Tite 4-hole distribution box to a PolyLok 7-hole distribution box which is acceptable to us. All components of the system are outside of the 50-feet setback to the pond. At the time of our visit, the existing septic tank had not yet been abandoned and the sewer line to the new septic tank was not yet installed. This was recently done and pictures of the installation of the new sewer line provided by the contractor. These pictures are included in our photograph log.

The purpose of the report was to provide design details for the OWTS in accordance with the 2018 Eagle County Environmental Health Department Onsite Wastewater Treatment System Regulation #43. The design services are supplemental to our agreement for professional services to Biscayne Trust WGS LLP dated June 5, 2019. PROPOSED CONSTRUCTION The existing cabin is a one and two-story, four-bedroom structure located in the SESE of Section 13, Range 87W, Township 3S, see Figure 1. The proposed renovation of the cabin will not add bedrooms. The cabin floor is over crawlspace. The location of the cabin is shown on Figure 2. It is planned to construct a new OWTS at the site for the cabin. The soil treatment area (STA) will be sized for the four bedrooms the cabin currently has. The proposed soil treatment area (STA) for the OWTS will be located to the southwest and downslope of the cabin as shown on Figure 2. Water service is provided by an onsite spring and storage tank located to the north of the cabin, see Figure 2. If proposed construction is different than that described, we should be contacted to re-evaluate the design recommendations. SITE CONDITIONS The cabin access is a gravel road parallel and to the southwest of West Fork Sheep Creek and by a bridge across the creek with the road extending to the east of the creek, see Figure 2. There are various sheds and fences on the property. The site is creek valley bottom which is moderately sloping down generally to the southeast at about 10% grade. Elevation difference from the cabin - 2 - Kumar & Associates, Inc. ® Project No. 19-7-359.02 to the planned STA is estimated at about 10 feet and elevation difference across the planned STA is estimated at about 3 or 4 feet. The cabin has a floor elevation slightly above adjacent ground surface. Two ponds are to the south of the cabin and the proposed STA as shown on Figures 1 and 2. There is also an irrigation ditch located to the north and northwest of the cabin. Vegetation consists of grass, weeds and brush. The cabin is currently served by an OWTS. A plastic septic tank is to the south of the cabin in the area of the proposed new septic tank and is estimated to be about 1,000 gallons volume. The existing STA is in the general vicinity of the proposed STA. SUBSURFACE CONDITIONS The field exploration for the OWTS was conducted on July 19, 2019. Two profile pits (Profile Pits 1 and 2) were excavated with a backhoe at the approximate locations shown on Figure 2 to evaluate the subsurface conditions at proposed STA for the OWTS. The pits were logged by a representative of Kumar & Associates. Logs of the profile pits are provided below. Log of Profile Pit 1 Depth USDA Classification 0’-1’ TOPSOIL; organic loam, firm, moist, dark brown. 1’-8’ SANDY LOAM; gravelly, weak blocky structure, stiff, slightly moist to very moist with depth, brown. • Disturbed bulk sample obtained from 3 to 4 feet. • Bottom of pit @ 8 feet. • Water seepage encountered at 8 feet. • No redoximorphic features observed at time of pit excavation. Log of Profile Pit 2 Depth USDA Classification 0’-1’ TOPSOIL; organic loam, firm, moist, dark brown. 1’-2’ EXISTING SOIL TREATMENT AREA; 8” diameter perforated, corrugated, polyethylene pipe 2’-8’ SANDY LOAM to LOAM; gravelly, weak blocky structure, stiff, slightly moist to moist with depth, brown. • Bottom of pit @ 8 feet. • No free water or redoximorphic features observed at time of pit excavation. - 3 - Kumar & Associates, Inc. ® Project No. 19-7-359.02 The soils encountered in profile pits below, about nil to 1 foot of topsoil, consisted of Gravelly Sandy Loam to the pit depths of 8 feet. Profile Pit 2 encountered the existing STA from 1 to 2 feet depth. The soil was classified as Sandy Loam with a gravel content of 25 to 30%. Groundwater seepage was encountered in the Profile Pit 1 at 8 feet deep at the time of excavation. No indications of seasonal higher groundwater were observed in the pits. Based on the tactile profile pit evaluations, the soils at the STA have been classified as Type 2A per State regulations, which equates to a long-term acceptance rate (LTAR) of 0.50 gallons per square foot per day. OWTS ANALYSIS Based on the site conditions and profile pit evaluations, the evaluated area should be suitable for a conventional infiltration soil treatment system consisting of chambers in a trench configuration. The base of the soil treatment trenches will be in Sandy Loam soils (Soil Type 2A) for which we will use an LTAR of 0.50 gallons per square foot per day to size the STA. The system will be designed for four bedrooms and an average daily flow of 75 gallons per person with double occupancy in the first three bedrooms and single occupancy in the fourth bedroom. The effluent will gravity flow from the cabin to the septic tank for primary treatment and then gravity flow to the STA for dispersal and final treatment. The STA will consist of four trenches with Infiltrator Quick 4 Plus Standard chambers. Equal distribution will be provided to the chambers and trenches by a distribution box. A 50 feet setback is required to the creek and ponds from the proposed STA. As designed, the STA is about 65 feet from the creek and about 60 feet from the nearest pond. A 20 feet setback is required from the cabin to the proposed STA. A 25 feet setback is required from the proposed STA to any potable water supply lines. The water supply line appears to be well away from the OWTS. If the water supply line is within 25 feet of the proposed STA, we should be notified for - 4 - Kumar & Associates, Inc. ® Project No. 19-7-359.02 additional recommendations. The existing irrigation ditch is about 90 feet from the planned STA. The existing septic tank, piping and STA should be abandoned per Eagle County regulations. We believe removal of the tank, piping and STA is the more desirable approach. We should observe the STA trench excavations at the time of construction to determine if subexcavation of the existing system field soils and replacement with concrete sand is needed. DESIGN RECOMMENDATIONS The design recommendations presented below are based on the proposed construction, the site and subsurface conditions encountered and our experience in the area. A layout of the proposed OWTS components is provided on Figure 2. If conditions encountered during construction are different than those that are described in this report, contact us to re-evaluate our design recommendations. SOIL TREATMENT AREA • The STA will consist of four trenches with 16 Infiltrator Quick 4 Plus Standard chambers placed in the native Sandy Loam soils (64 chambers total). Equal distribution will be provided to the trenches by a distribution box. • The STA was sized based on an LTAR of 0.50 gallons per square feet per day. • Each chamber was allowed 12 square feet of area. A 30% reduction of the STA size was applied for use of Infiltrator chambers in a trench configuration. The total STA design size is 768 square feet. Soil treatment area calculations are shown on Figure 3. • A minimum of four feet of undisturbed soil between the trenches is required. • A minimum of 12 inches and a maximum of 24 inches of cover soil should be placed over the top of the chambers. • The trenches should be oriented along ground contours to minimize soil cut and cover. • The base and sidewalls of the trench excavations should be scarified prior to the chamber - 5 - Kumar & Associates, Inc. ® Project No. 19-7-359.02 placement. • Backfill should be graded to deflect surface water away from the STA and should be sloped at 3 horizontal to 1 vertical or flatter. A swale to divert surface water run-off may be needed along the up-slope side of the STA. • Disturbed soil should be re-vegetated as soon as possible with a native grass mix. No trees, shrubs or other plants with deep roots should be planted on or near the STA as this may damage the system piping. • Four-inch diameter inspection ports should be installed vertically into the knockouts provided in the Infiltrator end caps. Install ports at each end of each trench. The inspection port piping should be screwed into the top to the chambers and should not extend down to the ground surface inside the chambers. The inspection ports should extend at least 8 inches above the finished ground surface or be protected in a valve box at finished grade. • A plan view of the STA is presented on Figure 4 and a cross section of the STA is presented on Figure 5. • The STA must maintain a minimum 50 feet setback from West Sheep Fork Creek, the ponds and the irrigation ditch. • The STA must maintain a minimum 20 feet setback from the cabin. • The STA must maintain a minimum 25 feet setback from the on-site water supply line. OWTS COMPONENTS Recommended OWTS components provided below are based on our design details and our experience with the specific component manufacturers. Equivalent components may be feasible but need to be approved by us prior to construction. Septic Tank • A Valley Precast 1,250 gallon, two-chamber septic tank will be used for primary treatment. A detail of the tank is provided as an attachment to the report. • An effluent filter should be installed in the tank outlet tee. - 6 - Kumar & Associates, Inc. ® Project No. 19-7-359.02 • The tank must be a minimum of five feet from any structure and from the STA. The tank must be a minimum of 10 feet from any potable water supply lines. • The tank must be set level. The excavation bottom must be free of large rocks or other objects that could damage the tank during placement. A road base or gravel bedding material may be needed to prevent tank damage during placement and act as a leveling course. • The tank lids must extend to final surface grade and made to be easily located. • Install the tank with 2 feet minimum cover soil for frost protection. Maximum tank soil cover is 4 feet. Sewer Pipe • The sewer line to the septic tank should not be less than the diameter of the building drains and not less than 4 inches in diameter. • The sewer pipe should have a rating of SDR35 or stronger. Schedule 40 PVC pipe is required beneath all driveway surfaces. • The sewer pipe should be sloped between 2% to 4% to help limit disturbance of solids in the tank and potential sewage bypass of the first chamber of the tank. If a steeper slope is needed, this can be accomplished with vertical step-downs in the sewer line. • A minimum 36 inches of cover soil should be provided over the sewer pipe. Paved areas, patios or other areas without vegetative cover may be more susceptible to frost and we recommend 48 inches of soil cover over the sewer pipe in these areas, and the pipe be insulated on top and sides with 2-inch-thick blue foam insulation board. If adequate soil cover is not possible, we should be contacted for re-evaluation prior to installation. • The sewer pipe should be bedded in compacted ¾ inch road base or native soils provided that the native soils contain no angular rocks or rocks larger than 2½ inches in diameter to help prevent settlement of the pipe. Sags in the pipe could cause standing effluent to freeze and damage the piping. • Install cleanout pipes within 5 feet of the building foundations, where the sewer pipes bend 90 degrees or more and every 100 feet of sewer pipe. • All 90-degree bends should be installed using a 90-degree long-sweep or by using two 45-degree elbows. - 7 - Kumar & Associates, Inc. ® Project No. 19-7-359.02 • The sewer line location shown on Figure 2 is considered conceptual. We assume that there will be only one sewer line exiting the cabin. It is the responsibility of the owner/contractors to locate all sewer line exit locations and connections to the septic tank. We should be notified if there are more than one sewer line exiting the cabin. Effluent Transport Piping • The effluent transport pipe should be 4-inch diameter SDR35 piping sloped at a 2% minimum to flow from the septic tank to the distribution box and from the distribution box to each trench. Piping should extend at least 6 inches into the top knockout provided in the Infiltrator end caps and be screwed in place. Splash plates should be installed beneath the inlet piping to help limit scouring of the infiltrative soil surface in the chambers. • The effluent transport pipe should be bedded in compacted ¾ inch road base or native soils provided that the native soils contain no angular rocks or rocks larger than 2½ inches in diameter to help prevent settlement of the pipe. Sags could cause standing effluent to freeze and damage to the piping. • A minimum 18 inches of cover soil should be provided over the effluent transport pipe. Paved areas, patios or other areas without vegetative cover may be more susceptible to frost. We recommend 48 inches of soil cover over the effluent pipe and insulation with at least 2 inches of rigid foam insulation in these areas. If adequate cover soil is not possible, we should re-evaluate the condition prior to installation. • The effluent pipe should be double encased with larger diameter Schedule 40 PVC pipe underneath driveway surfaces and be provided with at least 48 inches of soil cover and be insulated on top and sides with 2-inch-thick foam insulation board. • All 90-degree bends should be installed using a 90 degree long-sweep or by using two 45-degree elbows. Distribution Box • The distribution box will be used to equally divide effluent flow between the trenches. We recommend the Tuf-Tite 6-Hole Distribution Box since it is easily accessible from - 8 - Kumar & Associates, Inc. ® Project No. 19-7-359.02 ground surface for maintenance. A copy of the distribution box detail is provided as an attachment to this report. • The distribution box outlet pipes should be equipped with Tuf-Tite speed levelers for ease of initial setup and adjustment over time. • The distribution box should be a minimum of 18 inches below grade with risers and an access lid at or above grade. • The distribution box must be accessible from ground surface for inspection and maintenance per State guidelines. • The effluent line from the septic tank should be directed downward into the distribution box with a 90-degree elbow inside the box. • The distribution box must be installed level on a compacted road base subgrade to ensure equal effluent distribution. If settlement of the distribution box occurs, unequal effluent distribution may take place which could cause hydraulic overload of one of the trenches and potential failure. The distribution box should be monitored periodically, and the speed levelers should be adjusted as necessary for levelling. The ground surface above and around the distribution box should be graded to drain away surface water to prevent standing water near the distribution box. OWTS OPERATION AND MAINTENANCE The OWTS will require periodic inspection and maintenance to function properly. A properly designed, installed and maintained system can greatly increase its lifespan. The level of maintenance will vary depending on the complexity of the system and water use habits of the residents. We recommend that an OWTS Operation and Maintenance (O&M) Manual be developed. Depending on the complexity of the system, a contract with an OWTS maintenance provider may be prudent. Below are some basic recommendations for the OWTS O&M. OWTS HOUSEHOLD OPERATION • Use of high efficiency water fixtures is recommended to decrease the hydraulic load on the OWTS system. • Fix plumbing leaks immediately as this may cause a hydraulic overload of the soil - 9 - Kumar & Associates, Inc. ® Project No. 19-7-359.02 absorption system. • Do not irrigate the area on top of or directly upgradient of the soil absorption field as this may cause a hydraulic overload. • Do not dispose of household waste down drains as this may clog or damage OWTS components. Examples of household waste includes: dental floss, cotton swabs, coffee grounds, paper towels, feminine products and many other kitchen and bath items. • Use of kitchen garbage disposals is not recommended. If a garbage disposal is utilized, kitchen wastewater should be screened thoroughly. Many kitchen solids are not decomposed in the septic tank and may cause increased tank pumping frequency. • Do not dispose of household chemicals, greases, oils, paints, hot tub water or water softener backwash in household drains. A separate drywell, if feasible, may be necessary for hot tub water or water softener backwash disposal. • Limit the use of bleach as this may harm useful bacteria in the septic tank and soil absorption system. • Liquid dishwasher and clothes washer detergent is recommended for households served by an OWTS. Clay substances used as fillers in powder detergents may result in clogging of the soils absorption system. • The effluent in septic tanks can freeze during extended periods of non-use in cold weather. We recommend that a tank heater be installed in this system to help prevent freezing. OWTS MAINTENANCE • Inspect the septic tank, pump vault filter, distribution box and STA at least annually for problems or signs of failure. • The filter should be cleaned annually by spray washing solids into the first chamber of the septic tank. • The septic tank should be pumped and cleaned every 3 to 5 years depending on use. Longer pumping intervals may increase the amount of solids that reach the STA, which may shorten its life span. • Pumping of the septic tank should take place when the level of the sludge and scum - 10 - Kumar & Associates, Inc. ® Project No. 19-7-359.02 layers combined take up about 25 to 33% of the capacity of the first chamber of the tank. OWTS CONSTRUCTION OBSERVATION The Eagle County Environmental Health Department requires that the designer of the system provide a record drawing and certification of the OWTS construction (As-Built inspection). We should be provided with at least 48-hour notice prior to the installer needing the inspections. Prior to issuance of our certification letter, we require observation of all system components prior to backfill. The number of site visits required for the inspection will depend on the installer’s construction schedule. LIMITATIONS responsible for technical interpretations by others of our information. As the project evolves, we should provide continued consultation and field services during construction to review and monitor the implementation of our recommendations, and to verify that the recommendations have been appropriately interpreted. Significant design changes may require additional analysis or modifications to our design. It is our opinion that the designed location of the OWTS components does not violate any setback requirements of the current Eagle County Regulations. Below is a table of common minimum horizontal setbacks to OWTS components. Refer to the Eagle County Regulations for a complete list of required setbacks. We recommend the OWTS components be surveyed by a Professional Colorado Land Surveyor.
