Box 2258 Eagle, Colorado 81631 ahalminski@evanschaffee.com RE: Final approval of the: Septic System Installation, OWTS-016647-2019 Property location: 1066 Polar Star Dr, Eagle Area, Parcel # 21094101009 Mr. Halminski This letter is to inform you that the above-referenced, OWTS-016647-2019 permit, has been inspected and finalized. This OWTS permit was approved and sized to serve a total of five (5) bedrooms. Please be advised that the addition and connection to a potential ADU may require further permitting by Eagle County. Additional information about the maintenance your septic system needs can be accessed through our website links, provided on the Environmental Health Department’s septic system resource page. 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 soil treatment area 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. If you have any questions regarding this information, please contact us at (970) 328 -8755 and reference the OWTS septic permit number.

Box 2258 Eagle, Colorado 81631 (ahalminski@evanschaffee.com) Project No. 18-7-724.02 Permit No. OWTS-016647-2019 Subject: Certification of Onsite Wastewater Treatment System, Proposed Residence, Lot 4, Filing 1, Kaibab Subdivision, 1066 Polar Star Drive, Eagle County, Colorado Dear Andy: A representative of Kumar & Associates observed the installation of the Onsite Wastewater Treatment System (OWTS) for the residence currently under construction at the subject site as required by the Eagle County Environmental Health Department. Our observations and recommendations are presented in this report. The services are supplemental to H-P/Kumar’s (now Kumar & Associates) agreement for professional services to Andy Halminski dated December 3, 2018. We previously designed the OWTS for the residence as submitted in our report dated May 23, 2019, Project No. 18-7-724.02. The system was designed for five bedrooms. The OWTS was installed under Eagle County Permit Number OWTS-016647-2019 by Icon, Inc. We performed our evaluation on August 8, 2019. The OWTS components observed included: sewer line, cleanout, 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 location of the STA was moved from the northwest side to the southeast side of the lot to better fit the contours and setbacks for the STA. One additional profile pit (Profile Pit 3) was excavated on August 8, 2019 as per discussion with the Eagle County Environmental Health Department. We observed the soils encountered in the profile pit to be consistent with the soils previously encountered in Profile Pits 1 and 2 at the site. The soils encountered at Profile 3, below about 6 inches of topsoil, consisted of Loam to the pit depth of 8 feet.

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 Regulations and the Colorado Department of Public Health and Environmental Regulation #43. The services are supplemental to our agreement for professional services to Andy Halminski dated December 3, 2018. We previously conducted a subsoil study for foundation design of the proposed residence at the site and presented our findings in a report dated January 2, 2019, Project No. 18-7-724. PROPOSED CONSTRUCTION The residence will be a two-story structure over crawlspace with an attached garage located near the middle portion of the lot as shown on Figure 1. The ground floors will have finish elevations slightly above the existing ground surface. The residence will include 4 bedrooms with a possible fifth bedroom above the garage. The soil treatment area (STA) will be sized for 5 bedrooms. The proposed soil treatment area (STA) for the OWTS will be located to the southwest of the proposed residence shown on Figure 1. Water service will be provided by public water supply from Polar Star Drive near the southwest corner of the lot. The route of the water line to the residence has not yet been determined but the required set-backs from the OWTS should be considered for its location. If proposed construction is different than that described, we should be contacted to re-evaluate our design recommendations. - 2 - Kumar & Associates, Inc. ® Project No. 18-7-724.02 SITE CONDITIONS The lot is vacant and located in the valley bottom of a northeast to southwest trending small valley with hillside slopes rising to the northwest and southeast. The valley bottom is strongly sloping down to the southwest at grades estimated at about 5 to 6%. Elevation difference from the residence to the planned STA is estimated at about 6 to 8 feet and across the STA foot-print is estimated at about 3 or 4 feet. Vegetation consists of grass and weeds with scattered sagebrush. Bedrock of the Eagle Valley Evaporite is exposed on the nearby valley sides. SUBSURFACE CONDITIONS The field exploration for the OWTS was conducted on April 26, 2019. Two profile pits (Profile Pits 1 and 2) were excavated with a backhoe at the approximate locations shown on Figure 1 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’-½’ TOPSOIL; organic loam, firm, slightly moist, brown. ½’-3’ LOAMY SAND; gravelly, single grain structure, medium dense, slightly moist, brown. 4’-8’ LOAM; moderate blocky structure, stiff, slightly moist, brown • Disturbed bulk sample obtained from 3 to 4 feet. • Bottom of pit @ 8 feet. • No free water or redoximorphic features observed at time of pit excavation. Log of Profile Pit 2 Depth USDA Classification 0’-½’ TOPSOIL; organic loam, firm, slightly moist, brown. ½’-8’ LOAM; moderate blocky structure, stiff, slightly moist, brown. • Bottom of pit @ 8 feet. • No free water or redoximorphic features observed at time of pit excavation. - 3 - Kumar & Associates, Inc. ® Project No. 18-7-724.02 The soils encountered in profile pits below about 6 inches of topsoil consisted of nil to about 3 feet of Gravelly Loamy Sand overlying Loam to the pit depths of 8 feet. Hydrometer and gradation analyses were performed on a disturbed bulk sample of the soils from Profile Pit 1 from 3 to 4 feet depth with the results provided on Figure 2. The tested sample (minus No. 10 size sieve fraction) classifies as Loam per the USDA system. Based on the profile pit tactile evaluations and laboratory testing, the soils have been classified as Soil Type 2 per State regulations. No free water was encountered in the pits nor indications of seasonal high groundwater observed at the time of the pit excavations. Based on the tactile profile pit evaluations, the soils at the STA have been classified as Type 2 per State regulations, which equates to a long-term acceptance rate (LTAR) of 0.60 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 Loam soils (Soil Type 2) for which we will use an LTAR of 0.60 gallons per square foot per day to size the STA. The system will be designed for five bedrooms and an average daily flow of 75 gallons per person with double occupancy in the first three bedrooms and single occupancy in the other two bedrooms for a total of 8 persons. The effluent will gravity flow from the residence to the septic tank for primary treatment and then gravity flow to the STA for dispersal and final treatment. The STA will consist of three trenches with Infiltrator Quick 4 Plus Standard chambers. Equal distribution will be provided to the chambers and trenches by a distribution box. A 10 feet minimum setback from the STA is required to the property lines. The setbacks are shown on Figure 1. A 25 feet setback is required from the proposed STA to any potable water supply lines. The location of the water supply line is currently not designed. If the water supply - 4 - Kumar & Associates, Inc. ® Project No. 18-7-724.02 line is within 25 feet of the proposed STA, we should be notified for additional recommendations. 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 1. If conditions encountered during construction are different than those that are described in this report, please contact us to re-evaluate our design recommendations. SOIL TREATMENT AREA • The STA will consist of four trenches with 15 Infiltrator Quick 4 Plus Standard chambers placed in the native Loam soils (60 chambers total). Equal distribution will be provided to the trenches by a distribution box. • The STA was sized based on an LTAR of 0.60 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 is 720 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 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. • 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 - 5 - Kumar & Associates, Inc. ® Project No. 18-7-724.02 provided in the Infiltrator end caps. Install vents 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 25 feet setback to the on-site water supply line. The STA must be a minimum of 10 feet from the lot property 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 1,500 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. • The tank must be a minimum of five feet from the residence 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. - 6 - Kumar & Associates, Inc. ® Project No. 18-7-724.02 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 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 foundation, 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. • The sewer line location shown on Figure 1 is considered conceptual. We assume that there will be only one sewer line exiting the residence. 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 building. 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 - 7 - Kumar & Associates, Inc. ® Project No. 18-7-724.02 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 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 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 - 8 - Kumar & Associates, Inc. ® Project No. 18-7-724.02 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 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 - 9 - Kumar & Associates, Inc. ® Project No. 18-7-724.02 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, pump vault filter 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 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. - 10 - Kumar & Associates, Inc. ® Project No. 18-7-724.02 LIMITATIONS We have conducted this design in accordance with generally accepted engineering principles and practices in this area at this time. We make no warranty either expressed or implied. The recommendations provided in this report are based on the site conditions, profile pit evaluations and soil texture analysis, the proposed construction and our experience in the area. Variations in the subsurface conditions may not become evident until excavation is performed. If conditions encountered during construction appear different from those described in this report, we should be notified so that re-evaluation of the recommendations may be made. This report has been prepared for the exclusive use by our client for design purposes. We are not 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 with the exception of the sewer line which has been addresses in the design portion of this report. 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.

I also have an aerial as well to help clarify. The reason we want to move is that the infiltration field is getting pinched between the property line setback on the north and the driveway on the south.

Please remember that the water line location was not know and so not addressed on the plans, and a 25' setback must be maintained between the waterline and the STA. Please reflect these changes on your final certification and site plan. By the way, will you have the Giordano final ready soon? I believe our Admin received a call wondering it's status for final approval? Thanks for reaching out.
