Construction" <bmtike@centurytel.net> Kenny, As we discussed earlier today, you installed an On -site Wastewater Treatment System (OWTS) at 49 Kicking Horse Trail without having a valid permit in -hand. I'm sending this email as a courtesy to stress the importance of making sure that you always have a valid OWTS permit before installing a system. The sanctions that you expose WY Construction to when installing an OWTS without a permit can lead to both being fined as well as having the installer's license revoked for a year. We are disappointed when we are placed in the awkward position of having to consider such sanctions with any of our licensed contractors and ask that you always make certain that you always have a valid OWTS permit prior to doing any OWTS work in the future. It is very important that you read the permit language carefully to be sure the design that is approved for installation matches the design that you're working from and that the plans are followed exactly as depicted on the design. Be aware that often times, there are other requirements included in the permit that require special attention or additional actions that must be completed in order to get final approval. As a reminder, any time you come across issues that tempt you to digress from the design in any way, please be sure to contact the design engineer to discuss the changes and receive permission from us, in writing, before implementing any changes to the approved design. Permission to proceed may come in the form of an email or may require a permit amendment. Feel free to contact me with any concerns or questions and please "reply all" with the date on the HP Geotech design report as well as the date it was stamped so we know what is installed matches what we reviewed.

This permit was approved and sized for a total capacity for 5 bedrooms. Additional information about the maintenance your septic system needs can be accessed through web site links provided on the Environmental Health Department’s home page at http://www.eaglecounty.us/envHealth/ 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 and making sure your septic tank is on a pumping schedule, 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.

Turnipseed, AIA Attn: Brennen Fitzgerald PO Box 3388 Eagle, Colorado 81631 (brennen csstaia.com) Project No. 16-7-288 OWTS Permit No. 9-14-11540 Subject: As -Built Evaluation of Onsite Wastewater Treatment System, Proposed Milsap Residence, Lot 7. Filing 33, The Territories at Cordillera, 49 Kicking Horse Trail, Eagle County, Colorado Dear Brennen: As requested, representatives of H-P/Kumar observed the installation of Onsite Wastewater Treatment System (OWTS) for the proposed residence at the subject property as required by the Eagle County Environmental Health Department. This report summarizes our observations and recommendations. The services were supplemental to Hepworth-Pawlak Geotechnical's (now H-P/Kumar) agreement for professional services to Scott S. Turnipseed, AIA dated June 17. 2014. Hepworth-Pawlak Geotechnical previously designed the OWTS for the subject residence and presented our recommendations in a report dated August 21, 2014, Job No. 114 241 B. The system was designed for six bedrooms. We performed an initial As -Built evaluation on October 23 and 28, 2015. Additional As -Built evaluations were performed on August 10 and September 22, 2016. The OWTS was installed by W.Y. Construction under permit number 9-14-11540. The OWTS components observed included: sewer pipe, cleanouts, septic tank, dose tank, effluent pump and pump performance, effluent transport pipe, soil treatment area including sand placement for the mounded system, and the Iocations of these components. The position of the sewer pipe, septic tank, effluent transport pipe and soil treatment area were modified some from our design. The sewer pipe was constructed to exit the west side of the residence just north of the chimney, and the septic tank location was adjusted accordingly. The effluent transport pipe was reconfigured to enter the south side of the soil treatment area instead of the north side. The soil treatment area was angled to the northwest to align better with ground contours. All modifications were verbally approved by us prior to installation and will not change the overall performance of the design. H-P . KUMAR - --- �- - — - ----- . Project No. 16-7-288 Scott S. Turnipseed September 23, 2016 Page 2 The installation and locations of system components were verified as shown on Figure 1. Photographs of the OWTS installation are provided in the attached Photograph Log. It is our opinion that the OWTS was installed in general conformance with the August 21, 2015 design. The observations and recommendations presented above are based on our site observations and our experience in the area. We make no warranty either express or implied. Alterations to the system or improper backfill and site grading could affect the operation and effectiveness of the OWTS.

The report summarizes the site and subsurface conditions, and provides design details for the OWTS in accordance with the 2014 Eagle County Onsite Wastewater Treatment System Regulations and the Colorado Department of Public Health and Environment's Regulation #43. The services were performed as part of our agreement for professional services to Scott Turnipseed AIA, dated June 17, 2014. BACKGROUND INFORMATION Hepworth-Pawlak Geotechnical, Inc. (HP Geotech) previously prepared a subsoil study for foundation design for the property and submitted our findings in a report dated July 25, 2014, Job No. 114 241A. The report included a review of the site conditions, evaluation of the subsurface conditions and percolation testing which are the basis for our OWTS design. PROPOSED CONSTRUCTION The residence will be a six bedroom residence with an attached garage located on the property as shown on Figure 1. The proposed soil treatment area for the septic system is planned to the southwest of the residence. Two out buildings are also proposed. We understand that the out buildings will not have plumbing. If proposed construction is different than described, we should be contacted to re-evaluate our design recommendations SITE CONDITIONS The lot was vacant at the time of our field exploration and the ground surface appeared mostly natural. The terrain is a low knoll with strong slopes down to the northwest and west. Slope grades range from 8 to 15%. The slope grades become moderately steep on Job No. 114 241 B Gt~gteCh -2- the order of 20% further to the west in the area of the proposed soil treatment area. Vegetation consisted of grasses, weeds and sagebrush. SURFACE WATER AND WETLANDS There are two small ponds and apparent wetlands in the southwest corner of the building envelope over 200 feet from the proposed soil treatment area. WELLS The proposed well for the property is shown on Figure 1 adjacent to the driveway between the proposed residence and Out Building 1. A minimum 100 feet setback is required from the soil treatment area to the well and a 50 feet minimum setback is required from the septic tanks and sewer line to the well. SUBSURFACE INVESTIGATION The field exploration for the project was conducted on July 10, 2014. Two Profile Pits (Profile Pits I and 2) and three percolation test holes (P-1, P-2 and P-3) were excavated at the approximate locations shown on Figure I to evaluate the subsurface conditions. Logs of the Profile Pits are provided below. The subsoils encountered consisted of 6 inches of topsoil overlying strong -blocky Clay/Silty Clay Loam with subangular basalt rock fragments to the depth explored, 7Y2 feet. Log of Profile Pit 1 II 0-6" I TOPSOIL; loose, moist, dark brown. 6" 7Yz' CLAY LOAM -SILTY CLAY LOAM; with subangular basalt rock fragments, blocky shape, strong grade, medium dense to dense, brown to light brown with depth. • Bottom ofpit @ 7Y2 feet. • No free water was encountered during the pit excavation.

Job No. 114 241 B " &--c ,y -3- No free water or indications of seasonally shallow groundwater were observed in the pits and the subsoils were generally moist. The results of a gradation/hydrometer analyses performed on bulk sample of the subsoils from our previous study is attached as Figure 5. PERCOLATION TESTING Percolation tests were performed in the three test holes by HP Geotech on July 11, 2014. The percolation rates obtained ranged from about 45 to 180 minutes per inch (mpi) with an average percolation rate of about 95 mpi. Percolation test procedures outlined in Regulation #43 were not utilized and the results were only used for comparison of the USDA soil type. OWTS ANALYSIS Based on the profile pit soils, the infiltrative surface of the soil treatment area (STA) will be located in strong -blocky Clay/Silty Clay Loam. A Long -Term Acceptance Rate (LTAR) of 0.2 gallons per square foot per was estimated based Table 10-1 of Regulation #43. A two (2) feet thick mounded sand filter will be used; therefore, the design LTAR can be increased to 0.3 gallons per square foot per day for Treatment Level 2 at the infiltrative surface (basal area). Based on the soil conditions encountered, a mounded sand filter treatment system will be required for the site. A Long -Term Acceptance Rate (LTAR) of 0.3 gallons per square foot per day was used for sizing of the Clay Loam/Silty Clay Loam soils for the basal area of the mounded sand filter, which assumes Treatment Level 2. Sewage will be collected in the septic tank for primary treatment then gravity flow to a dosing tank where it will be pumped to the mounded soil treatment area (STA) for disposal. A 2 feet maximum cut depth will be allowed for the soil treatment area construction. DESIGN RECOMMENDATIONS The recommendations presented below are based on the site and subsurface conditions encountered and our experience in the area. If soil or site conditions encountered during construction are different than those that are described in this report please contact us and we will re-evaluate our recommendations. Job No. 114 241B G49tech M SOIL TREATMENT AREA • The soil treatment absorption field will consist of an aggregate bed that is 75 feet long by 12 feet wide constructed over a 2 feet thick mounded sand filter. The aggregate area was sized based on an LTAR for concrete sand of 1.0 gallons per square feet per day. • A basal sand area of 3,000 square feet will be required based on an LTAR of 0.3 gallons per square foot per day. Due to the sloping site, only the basal sand area directly beneath and downgradient of the aggregate bed has been included in the usable basal area. An area of 40 feet wide by 75 feet long has been assumed for the mounded soil treatment area. The soil treatment area calculations are presented on Figure 2. • Concrete sand is suitable for construction of the mounded sand filter. • Absorption area aggregate will be a minimum of 1 foot thick. See Figure 4 for the aggregate specifications. • A minimum of 12 inches and a maximum of 36 inches of cover soil should be placed over the soil treatment area aggregate. A layer of 2 ounce/ydz (or stronger) filter fabric should be placed over aggregate prior to backfill. Mirafr 160N or equivalent is recommended. • Backfill should be graded to deflect surface water away from the absorption area and should be sloped at 3H:1 V maximum. • Disturbed soil should be re -vegetated immediately with a native grass mix. No trees, shrubs or other plants with deep roots should be planted on or near the absorption area as this may damage piping. • Four inch diameter inspection ports should be installed at each corner and in the center of the aggregate beds. The inspection port piping should extend to the base of aggregate. The portion of the pipe that lies within the aggregate should be perforated. The inspection ports should extent at least 8 inches above the finished ground surface or be protected in a valve box at finished grade. • A plan view of the absorption area is presented as Figure 3 and a cross section of the absorption area is presented as Figure 4. Job No. 114 241B C-XZtech -5- OWTS COMPONENTS Recommended OWTS components were based on our design details and our experience with the specific component manufacturers. Equivalent components may be used if desired; however, they must meet our minimum recommendations and should be approved by the design engineer. Septic and Dose Tank • A 2,000 gallon, two chamber Valley Precast septic tank is proposed for primary treatment of sewage from the residence. The septic tank will be followed by a 500 gallon Valley Precast dose tank equipped with a submersible effluent pump. Pump specifications are provided in the Effluent Pumping System section of this report. A copy of the tank details are attached to this report after the figures. • The tanks must be set level. The excavation must be free of large rocks or other objects that could damage the tank during placement. A gravel base course bedding material may be necessary to prevent tank damage during placement and act as a leveling course. • Install tanks with 2 feet minimum cover soil for frost protection. Maximum tank burial depth is 4 feet. • The septic and dose tank lids must extend to finished grade. Sewer Pipe • The sewer line from the existing residence to the septic tank should not be less than the diameter of the building drain and not less than 4 inches in diameter. • The sewer pipe should have a rating of SDR35 or better. • Sewer pipe should be sloped at 2% minimum from the residence to the septic tank except for the last 10 feet, which should be sloped at 4% maximum (2% minimum) to help limit disturbance of solids in the tank. • A minimum 36 inches of cover soil should be provided over the sewer pipe. Paved areas, patios or other areas without vegetative cover maybe more susceptible to frost. 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. Job No. 114 241 B G-M Bch M • The sewer pipe should be bedded in compacted 3/ inch road base or native soils provided that the native soils contain no angular rocks or rocks larger than 2'/2 inches in diameter to help prevent settlement of the pipe. Sags could cause standing effluent to freeze and damage piping. • Install cleanout pipes within 5 feet of building foundation, where the sewer pipe bends 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 existing residence. It is the responsibility of the owner to locate all sewer line exit locations and connections to the septic tank. Effluent Transport Piping • The 1.25 inch diameter Schedule 40 effluent transport piping should be sloped at 2% minimum to drain from the dose tank to the absorption area manifold. • The effluent transport pipe should be bedded in compacted'/< inch road base or native soils provided that the native soils contain no angular rocks or rocks larger than 2%2 inches in diameter to help prevent settlement of the pipe. Sags could cause standing effluent to freeze and damage 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 sewer pipe in these areas. If adequate cover soil is not possible the effluent pipe should be insulated on top and sides with 2 inch thick foam insulation board and the design engineer should re-evaluate soil cover 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. Job No. 114 241B G "'Ptech -7- Effluent Pumping System • An Orenco PF3005, 115 volt, submersible effluent pump with a 1.25 inch diameter discharge assembly, or equivalent, will be required for the effluent pumping. • The maximum effluent transport distance from the pump discharge to the treatment area manifold is estimated to be 75 feet. • The elevation difference from pump discharge to the dose tank is estimated to be 10 feet. • The pump should be enclosed in an Orenco Biotube Pump Vault for effluent filtering and protection of the pump from vibration. • An equivalent pump must be capable of operating at 26.1 gallons per minute at 26.8 feet of total dynamic head. A pump performance curve is provided as an attachment to this report. • The floats should be set to provide a dose volume of approximately 95 gallons. To achieve the desired dose volume the upper ("ON") and lower ("OFF") floats should be set approximately 9 % inches apart. • The high water alarm float should be placed approximately 3 inches above the "ON" float in the dose tank. • A /s inch diameter weep hole should be drilled in the effluent transport line prior to exiting the dose chamber so the transport line can drain after each pumping cycle. 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 the lifespan of the OWTS. The level of maintenance will vary with the complexity of the system and water use habits of the residents. We recommend that an Operation and Maintenance (O&M) Manual be developed for the system to ensure that it is properly maintained. Depending on the complexity of the system a contract with an OWTS maintenance provider may also be prudent. Below are some basic recommendations for the O&M. Job No. 114 241B GtVgtech OWTS HOUSEHOLD OPERATION • Use of high efficiency water fixtures is recommended to decrease the hydraulic load on the OWTS. • 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 system as this may cause a hydraulic overload. • Do not dispose of household waste down household drains as this may clog or damage OWTS components. Examples of household waste that should not be disposed of in drains include: 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 for households served by an OWTS. 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 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 water in septic tanks can freeze during extended periods of non-use. We recommend that second homeowners install a tank heater to help prevent freezing. OWTS MAINTENANCE • Inspect the septic tank, dose tank, pump vault and soil treatment area at least annually for problems or signs of failure. • The pump vault filter should be cleaned annually by spray washing solids into the first chamber of the septic tank. Job No. 114 241B Gec�tech -9- • 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 soil absorption area, which may shorten its life span. • Pumping should take place when the level of the sludge and scum layers combined take up 25 to 33% of the capacity of the first chamber of the septic tank. OWTS CONSTRUCTION OBSERVATION The Eagle County Environmental Health Department requires that the designer provide an As -Built certification of the OWTS construction. We should be provided with at least 48 hour notice prior to the installer needing inspection. Prior to issuance of our certification letter, we require observation of all system components prior to backfill. The number of site visits required will be dependent on the installer's construction schedule. LIMITATIONS We have conducted this study in accordance with generally accepted engineering principles and practices in this area at this time. We make no warranty either expressed or implied. The conclusions and recommendations submitted in this report are based upon the site conditions, data obtained from the profile pits, percolation test holes, soil texture analysis, the proposed type of 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 the recommendations presented herein. Job No. 114 241B C3Mech -10- It is our opinion that the designed location of the OWTS 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 and verified by H-P Geotech prior to permitting.

This report summarizes our observations and recommendations. The services were supplemental to Hepworth-Pawlak Geotechnical’s (now H-P/Kumar) agreement for professional services to Scott S. Turnipseed, AIA dated June 17, 2014. Hepworth-Pawlak Geotechnical previously designed the OWTS for the subject residence and presented our recommendations in a report dated August 21, 2014, Job No. 114 241B. The system was designed for six bedrooms. We performed an initial As-Built evaluation on October 23 and 28, 2015. Additional As-Built evaluations were performed on August 10 and September 22, 2016. The OWTS was installed by W.Y. Construction under Eagle County permit number 9-14-11540. The OWTS components observed included: sewer pipe, cleanouts, septic tank, dose tank, effluent pump and pump performance, effluent transport pipe, soil treatment area including sand placement for the mounded system, and the locations of these components. The position of the sewer pipe, septic tank, effluent transport pipe and soil treatment area were modified some from our design. The sewer pipe was constructed to exit the west side of the residence just north of the chimney, and the septic tank location was adjusted accordingly. The soil treatment area was angled to the northwest to align better with ground contours. All modifications were verbally approved by us prior to installation and will not change the overall performance of the design. Pump performance calculations were verified and no modifications to the design were required. Scott S. Turnipseed October 3, 2016 Page 2 Project No. 16-7-288 The installation and locations of system components were verified as shown on Figure 1. Photographs of the OWTS installation are provided in the attached Photograph Log. It is our opinion that the OWTS was installed in general conformance with the August 21, 2015 design. The observations and recommendations presented above are based on our site observations and our experience in the area. We make no warranty either express or implied. Alterations to the system or improper backfill and site grading could affect the operation and effectiveness of the OWTS. Please feel free to contact us if you have any questions regarding this letter. Respectfully, Jason A. Deem, Project Geologist Reviewed by David A. Young, P.E.
