Young on October 1, 2015. The OWTS is designed to serve an existing three bedroom ranch house (replacing an undocumented septic system), a new six bedroom bunkhouse and two bathrooms in anew barn for a total system design of nine bedrooms. Due to the size of the system, additional setback distances apply as provided by the design engineer. System consists of a 2,500 gallon, FLXX Front Range Precast, two -compartment septic tank and a FLXX Front range Precast 500 gallon electric lift station equipped with an Orenco PF 3005 effluent pump placed in an Orenco Biotube pump vault. Effluent will be pumped to an Orenco V6605 Automatic Distribution Valve (ADV) for sequential dosing of about 77 gallons of effluent to each of the five trenches. The ADV must be installed at the high point of the system. Access to all components must be or above grade and the dose chamber must be equipped with an audible and visual alarm. The soil treatment area (STA) consists of 2,250 square feet (prior to adjustments for chambers and pressure dosing) via the installation of 105 Infiltrator Quick 4 Plus chambers arranged in five shallow , trenches with 21 chambers on each trench as shown on the plans. Be sure to install at a maximum of one foot deep to avoid installing in the rocky substrate as identified by the design engineer. Contact the design engineer if the rocky substrate is encountered to receive recommendations for moving the STA to another location. The existing tank serving the ranch house must be abandoned in accordance with WQCC Regulation 43.9 (C.) and documented as such. Do not install in wet or frozen ground. Do not connect any drains from horse washing tot he OWTS. Contact the design engineer at least 48 hours in advance to conduct the necessary squirt test and all inspections necessary to certify the system; and to prepare the as -built drawings. System certification along with the as -built drawing, photos and documentation of proper tank abandonment must be submitted to, and approved by, Eagle County Environmental Health prior to the use of the system or occupancy of structures.

This permit was approved and sized for a total capacity for 9 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.

O. Box 4195 Eagle, Colorado 81631 (mccordconstruction@hotmail.com) Project No. 16-7-652 Permit No. OWTS-10-15-13710 Subject: Onsite Wastewater Treatment System As-Built Evaluation, Proposed Bunkhouse and Existing Ranch House and Stables/Barn, Colorado River Ranch, 12799 Colorado River Road, Eagle County, Colorado Dear Tom: As requested, H-P/Kumar is providing this Onsite Wastewater Treatment System (OWTS) As- Built evaluation for the bunkhouse currently under construction, and the existing ranch house and stables/barn, at the subject site. Our observations and recommendations are presented in this report which includes an As-Built site plan and photographs of the system. The services are supplemental to Hepworth-Pawlak Geotechnical (now H-P/Kumar) agreement for professional services to McCord Construction dated March 28, 2014. Hepworth-Pawlak Geotechnical previously designed the OWTS for the project and presented their recommendations in a report dated December 11, 2015, Job No. 114 101A. The system will provide treatment for the new bunkhouse as well as the existing ranch house and stables/barn. We performed our As-Built site evaluation on March 16, March 25 and November 2, 2016. The installation and locations of system components and the infiltrative surface soils were verified. The components as-built locations and elevations were also surveyed by Archibeque Land Consulting, Ltd. The locations of components shown on Figure 1 are the locations provided by the surveyor. The installer was McCord Construction. The OWTS components observed included: sewer pipes, cleanouts, septic and dose tanks, effluent transport pipe, soil treatment area, pump and pump operation and automatic distribution valve. The contractor was unable to obtain the Front Range Precast tanks specified in our design in a timely manner and elected to use Valley Precast tanks in the configuration shown on Figure 1. The design changes were verbally approved by us prior to installation. The tanks meet the minimum storage capacity required by the regulations, and it is our opinion that the change in tanks will not alter the effectiveness of the OWTS. Photographs of the OWTS installation are provided in the attached Photograph Log.

The purpose of this report was to provide design details for the OWTS in accordance with 2014 Eagle County Onsite Wastewater Treatment System Regulations and the Colorado Department of Public Health and Environment's Regulation #43. We previously prepared an OWTS design for the Red Barn Pavilion renovation at the ranch and submitted our findings in a report dated April 30, 2014, Job No. 114 101A. PROPOSED AND EXISTING CONSTRUCTION There is an existing three bedroom residence on the property that was constructed in 1955 according to Eagle County records. No details for the existing OWTS were available, however, we understand that it is located in the same general vicinity of the proposed soil treatment area (STA) for the subject design. A bunkhouse with six bedrooms will be constructed northeast of the existing ranch house. There is also a barn/stables structure under construction to the east of the bunkhouse which will have two bathrooms (and no showers). The three structures will share the OWTS. The shared STA will be located southeast of the existing ranch house. The existing and proposed buildings and facilities are shown on Figure 1. The OWTS will be designed for nine bedrooms for the combined flows from the three structures. If proposed construction is different than that described, we should be contacted to re- evaluate our design recommendations. SITE CONDITIONS The property consists of an approximately 1,000 acre size ranch about 12 miles north of Dotsero. Several existing structures are located on the property. The building site is lob No 114 101A �� Gg;bech -2- located in the northeast portion of the property. The area where proposed OWTS will be located is generally gently sloping terrain down to the southwest from the ranch access road. The Colorado River is located about 700 feet west of the proposed STA. There is an irrigation diversion along the river that flows to a pond about 375 feet northwest of the proposed STA. There is also an irrigation ditch about 160 feet southwest of the proposed STA. A 78 feet minimum setback is required from the STA to all surface water features. The domestic well for the property is located 153 feet west of the proposed STA. A 128 feet setback is required from the STA to the well. SUBSURFACE CONDITIONS The field exploration was conducted on March 16, 2015. Three profile pits (Profile Pits 1, 2 and 3) were excavated at the approximate locations shown on Figure 1 to evaluate the subsurface conditions. Logs of the profile pits are provided below. Log of Profile Pit 1 Depth USDA Classification 0-51/2' SANDY LOAM; strong granular structure, medium dense, slightly moist, brown. 5%z'-8' SAND; very gravelly with subround cobbles up to 12 inch diameter, strong granular structure, slightly moist, brown. • Bottom of pit @ 8 feet. • No free water ivas eticocuitered ditring excavation. • Bulk disturbed satqle obtained front 2 to 3 eet. Log of Profile Pit 2 Depth USDA Classification 0-1' SANDY LOAM FILL; strong granular structure, loose, slightly moist, brown. 1'-5' SAND; very gravelly with subround cobbles up to about 12 inches in diameter, strong granular structure, slightly moist, brown. • Bottom of pit @ 5 feet. • No free water was encounteredduring excavation. Job No. 114 101 A G tech -3- Log of Profile Pit 3 Depth USDA Classification 0-1'/z SANDY LOAM FILL; strong granular structure, loose, slightly moist, brown. 1'/z-6' SANDY LOAM; strong granular structure, medium dense, slightly moist, brown. 6'-8' SAND; very gravelly with subround cobbles up to about 12 inches in diameter, strong granular structure, slightly moist, brown. • Bottom of pit @ 8 feet. • No free water was encountered during excavation. The soils encountered consisted of about 1 to 6 feet of sandy loam overlying very gravelly sand with cobbles to the maximum depth explored, 8 feet. The upper 12 to 18 inches of soil in Profile Pits 2 and 3 appeared to be man -placed fill. A hydrometer and gradation analysis was performed on a disturbed bulk sample of the upper soils from Profile Pit 1 with the results provided on Figure 2. The tested sample classifies a sandy loam per the USDA system. Based on the subsurface conditions, textural analyses and laboratory testing, the soils have been classified as Soil Type 2 per State regulations, which equates to a long-term acceptance rate (LTAR) of 0.6 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 septic disposal system. The system should consist of infiltrators in a trench configuration. The base of the soil treatment trenches will be located in sandy loam soils (Soil Type 2) and are suitable for a conventional infiltration disposal system. The STA will be sized for nine bedrooms for the three buildings. An LTAR of 0.6 gallons per square foot per day will be used for the design of the STA. The sewage will gravity flow to the septic tank for primary treatment then gravity flow to the dose tank where it will be pressure dosed to the STA for disposal and final treatment. The STA will consist of five trenches with Infiltrator chambers. Equal distribution will be provided by an automatic distributing valve. Job No. 114 101 A G&tec ..1 -4- Based on the subsurface condition encountered, the sandy loam layer may be thinner or non-existent in some locations. The very gravelly sand below the sandy loam is not suitable for effluent treatment. If the very gravelly sand with cobbles is encountered during excavation, we should be contacted to provide recommendations for moving portions of the STA or sub -excavation and replacement with imported concrete sand to allow for the required 4 feet of suitable soils beneath the chambers. We recommend a maximum cut depth of about I foot to maximize the thickness of the sandy loam. This will require placement of at least 1 foot of fill over the STA for frost protection. We understand the existing STA for the ranch house is located in the same general vicinity of the proposed STA; however, it was not encountered during our subsurface exploration. If encountered during construction, we can provide recommendations for removal of the existing STA and any accumulated biomat material. 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. If conditions encountered during construction are different than those that are described in this report please contact us and we will re-evaluate our design recommendations. Locations of existing water lines in the area should be determined and sewer piping encased as needed, which we should review and provide recommendations at the time of construction. The existing known site conditions and proposed OWTS components are shown on Figure I. SOIL TREATMENT AREA • The treatment system will consist of five trenches with 21 Infiltrator Quick 4 Plus Standard chambers in each row (105 chambers total). • The STA was sized based on an LTAR of 0.6 gallons per square feet per day. • Each chamber was allowed 12 square feet of area. A 20% dosing reduction and a 30% chamber reduction in the STA was allowed per Eagle County regulations. Job No, 114 101 A -5- The total STA is 1,260 square feet. The soil treatment area calculations are shown on Figure 3. • The base and sidewalls of the trench excavations should be scarified prior to chamber placement. • A minimum of 12 inches and a maximum of 24 inches of cover soil should be placed over the chambers. • Backfill should be graded to deflect surface water away from the STA and should be sloped at 3 (Horizontal) to I (Vertical) maximum. • 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 absorption area 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 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 view of the STA is presented on Figure 5. • Cleanouts are required at the ends of each pressure distribution lateral. A typical cleanout detail is provided as Figure 6. 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 and Dose Tank • A 2,500 gallon, two chamber Front Range Precast septic tank is proposed for primary treatment. The septic tank will be followed by a 500 gallon dose ("Lift Job No. 114 101A S-2 Station') tank equipped with a submersible effluent pump. A copy of the tank details are provided as attachments to this report. • The tanks must be set level. The excavation bottom must be free of large rocks or other objects that could damage the tank during placement. A gravel or road base bedding material may be necessary to prevent tank damage during placement and act as a Ieveling course. • Install tank with 2 feet minimum cover soil for frost protection. Maximum tank soil cover depth is 4 feet. • The septic lids must extend to final surface grade and made to be easily located. • The existing septic tanks should be abandoned per Eagle County Regulations. Typically the tanks are pumped dry and the lid and bottom of the tank is crushed and backfilled with onsite soil. The tanks may also be removed and disposed of. Sewer Pipe • The sewer line from the structures 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 pipes should have a rating of SDR35 or better. Schedule 40 PVC is required undenzeath all roadtvay surfaces. • The sewer pipes 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 pipes. 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 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 pipes should be bedded in compacted 3/4 inch road base or native soils provided that the native soils contain no angular rocks or rocks larger than 21/z inches in diameter to help prevent settlement of the pipe. Sags could cause standing effluent to freeze and damage piping. Job No. 114 tolA G -7- Install cleanout pipes within 5 feet of the building foundations, where the sewer pipes 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 locations shown on Figure 1 are considered conceptual. We assume that there will be only one sewer line exiting each structure. It is the responsibility of the owner and/or contractor to locate all sewer line exit locations and connections to the septic tank. We should be notified if there are other sewer lines exiting the structures. Effluent Transport Piping • 1.5 inch diameter Schedule 40 effluent transport piping should be sloped at 2% minimum to drain back from the ADV to the dose tank and from the ADV to the manifolds in each aggregate bed. The ADV must be the high point of the system. • The effluent transport pipe should be bedded in compacted 3/4 inch road base or native soils provided that the native soils contain no angular rocks or rocks larger than 21/2inches in diameter to help prevent settlement of the pipe. Sags in the pipes could cause standing effluent to freeze and damage piping. • 18 inches minimum 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(s) 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. 114 101 A Ma 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 effluent pumping. • The maximum effluent transport distance from the pump discharge to the ADV is estimated to be 55 feet. The distance from the ADV to the furthest trench is estimated to be an additional 52 feet. • The elevation difference from pump discharge to the STA manifold is estimated to be 12 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 15.0 gallons per minute at 26.0 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 82 gallons. The actual dose volume will be about 77 gallons assuming 5 gallons of drainback in the transport line. To achieve the desired dose volume the upper ("ON") and lower ("OFF") floats should be set approximately 8 inches apart. • The flow differential between the first and last orifices is estimated to be 4.1 %. • The high water alarm float should be placed approximately 3 inches above the "ON" float in the dose tank. The high water alarm must be wired on a separate electrical circuit from the pump. • A Va inch diameter weep hole should be drilled in the effluent transport line prior to exiting the dose tank so the transport line can drain after each pumping cycle. Automatic Distributing Valve • An Orenco V6605 Automatic Distributing Valve (ADV) will be used to alternate doses to the five trenches. • The ADV must be installed level and must be the high point in the system. • The ADV should be installed in a sprinkler box, or equivalent, such that it is serviceable and protected from freezing. We recommend the ADV be equipped with heat tape for additional frost protection during winter months. Job No. 114 101 A WE • We recommend the ground surface be graded away from the ADV in all directions. Improper surface drainage could cause standing water to freeze and damage the valve and/or piping. • The valve has clear sections of pipe that should be inspected at least annually to ensure that it is alternating doses to each trench. 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. a 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 household 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. Job No. 114 101 A G&teCh * 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, effluent filter and soil treatment area at least annually for problems or signs of failure. • The effluent filter should be cleaned annually by spray washing solids into the first chamber of the septic tank. • 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 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 from 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 an As -Built certification of the OWTS construction. We should be provided with at least 48 hour notice prior to the installer needing the As -Built 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 instalIer's construction schedule. Job No. 114 101A - G&hech Mile 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. 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 the system permitting.

Should print to scale at 11x17. The purple print was labeled building envelope w/ some non -essential notes. I turned that layer off. Here are some comments on your other questions. Looks like Tom was able to address the existing sewer line question. Other site features: There are ditches located west of the bunkhouse and southwest of the soil treatment area and a pond west of the exist in ranch house well outside of the required setbacks from sewer and effluent lines, septic tanks, and the STA. I changed the color to blue on Figure 1 to make it a bit easier to see. The closest we come to the setback is —110 feet from the sewer line outlet of the new bunkhouse to the edge of ditch to the west. There will be two areas where we cross water lines and sewer lines. They recently replaced the water lines and Tom McCord went ahead and sleeved the water lines w/ Sch. 40 PVC ±40' on each side of the proposed crossings. Sewer line length: Yes, the length is more than we would typically see in a residential scale application; however, gravity sewers have proven to be quite reliable keeping solids moving downhill as long as they are installed properly. I don't really have any concern as long as the pipe is properly bedded w/ a slope between 2-4%. 1 also tried to minimize bends as much as possible in my layout. Leaky fixtures: This is a concern with every septic system we put in the ground. I don't really see how this system is any different. All we can do is educate owners, ranch managers, etc. as best we can. Soil Type: We are certainly using all of the suitable soil we observed in the profile. The upper sandy loam we observed looked great so I'm trying to use it and based on what I saw we're close, but good. We can look at another pit or two to fine tune where the system will be placed. Let me know if you have any other questions. https://maiI.google.com/mail/ca/u/0/?ui=2&ik=1141485fcl&view=pt&as from=jdeem%40hpgeotech.com&as_sizeoperator=s sl&as sizeunit=s_smb&as subs... 1/3 11/9/2015 Eagle County Government Mail - RE: OWTS 10-15-13710 Thanks, JD Jason A.

Deem; Dave Young; Tom McCord Cc: #environment Subject: OWTS 10-15-13710 I've initiated the review of the OWTS proposed to serve the stable/barn, bunkhouse and existing ranch house and have a couple of questions and/or comments. First, could I get an electronic copy of Figure 1 (overall site plan) that I could enlarge to read the detailed notes, along with a key. I can't quite make out the red or purple print and want to understand the other features that might affect the OWTS design. Two things that concern me in general is the distance that solids and liquids will need to travel to get the the tank after passing under what appear to be driveways; and the risk of having a leaky fixture in any one of the uses causing a hydraulic overload/ failure of the STA. The design appears to be technically OK but I'm a little worried about the soil turning into a type 0 as was indicated in the design, just a few inches under the more suitable silt. Do you think additional investigation would be appropriate? The existing ranch house may have a cast iron sewer. Can the entire sewer pipe be replaced or are you envisioning a connection between the existing pipe and the new SDR35? May want to call out not using a rubber gasket like Calder or Fernco?

The purpose of this report was to provide design details for an 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 are supplemental to our agreement for professional service to McCord Construction dated March 28, 2014. BACKGROUND INFORMATION Hepworth-Pawlak Geotechnical, Inc. (HP Geotech) previously performed a subsoil study for foundation design for the site, and submitted our findings in a report dated May 15, 2015, Job No. 114 10IA. We also provided comments regarding a septic disposal system for the Red Barn in a letter dated June 5, 2014, Job No. 114 101A. A 2,000 gallon septic tank was installed in 2014 for temporary holding of wastewater from the Red Barn and is planned to be incorporated into the current OWTS design. PROPOSED CONSTRUCTION The Red Barn, which was renovated in 2014, consists of a two story structure located as shown on Figure 1. The structure will be utilized as an event facility for ranch functions and typical part-time use. Fixtures at the Red Barn will consist of a kitchen on the upper level, two bathrooms with showers on the lower level and an outdoor bathroom and shower. The OWTS soil treatment area.(STA) will be located southeast of the Red Barn. If proposed construction is different than that described, we should be contacted to re- evaluate our design recommendations. SITE CONDITIONS The property consists of an approximately 1,000 acre size ranch about 12 miles north of Dotsero. Several existing structures are located on the property. The Red Barn is in Job No. 114 101 A -2- about the middle portion of the property. The area where the Red Barn and proposed OWTS are located is generally gently sloping terrain down to the west towards the Colorado River which borders the property. The area where the soil treatment area is proposed is approximately 18 to 20 feet in elevation above the river level. SUBSURFACE CONDITIONS The field exploration was conducted to evaluate the subsurface conditions at the site on March 16, 2015. Two profile pits (Profile Pits 1 and 2) were excavated at the approximate locations shown on Figure 1. Logs of the profile pits are provided below. The soils encountered consisted of about 4 feet of moderate, blocky Sandy Loam with Gravel overlying weak, blocky Silt Loam to the depth explored, 8 feet. A hydrometer and gradation analysis was performed on a disturbed bulk sample from the assumed infiltrative surface with the results provided on Figure 2. The tested sample classifies a Sandy Loam with Gravel per the USDA system. Based on the subsurface conditions and laboratory testing, the soils have been classified as Soil Type 2 per Colorado State regulations, which equates to a long-term acceptance rate (LTAR) of 0.6 gallons per square foot per day.

Job No. 114 101 A -3- OWTS ANALYSIS Based on the profile pit evaluations and laboratory testing, the base of the soil treatment trenches will be located in Sandy Loam (Soil Type 2) and is suitable for a conventional infiltration disposal system. The STA will be sized for a maximum daily usage of 50 persons at a usage of 15 gallons per person per day. A LTAR of 0.6 gallons per square foot per day was used for sizing in the Sandy Loam soils. The sewage will gravity flow to the septic tank for primary treatment then effluent will flow to the dose tank where it is pressure dosed to the STA for final treatment. The STA will consist of three trenches with Infiltrator chambers. Equal distribution will be provided by an automatic distributing valve. Based on elevation difference the tank effluent will need to be dose pumped to the STA. It is feasible to incorporate the existing 2,000 gallon tank at the site into the OWTS design. A second 500 gallon dosing tank will need to be installed which will include the pump system. 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. If conditions encountered during construction appear different than those that are described in this report, contact us and we will re-evaluate our design recommendations. SOIL TREATMENT AREA • The treatment system (STA) will consist of three trenches with Infiltrator Quick 4 Plus Standard chambers. Each trench will consist of 25 chambers (75 chambers total). The trench layout is provided in Figure 1. • The STA was sized based on an LTAR of 0.6 gallons per square feet per day. • Each chamber was allowed 12 square feet of area and a 30% reduction in the STA was allowed per Eagle County regulations. The total STA is 900 square feet. Soil treatment area calculations are shown on Figure 3. • The base and sidewalls of the trench excavations should be scarified to disturbed soils prior to chamber placement. Job No. 11410tA e tech • A minimum of 12 inches and a maximum of 24 inches of cover soil should be placed over the chambers. • Backfill should be graded to deflect surface water away from the absorption area and should be sloped at 3 Horizontal:I Vertical maximum. • 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 absorption area 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 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. OWTS COMPONENTS The recommended OWTS components provided below are based on our design 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 2,000 gallon, two chamber Valley Precast septic tank has been installed at the site for primary treatment and will remain. H-P Geotech inspected the septic tank installation in August of 2014. As -Built documentation of the tank installation will be provided following construction of the remaining portions of the OWTS. The septic tank will be followed by a 500 gallon Valley Precast dose tank equipped with a submersible effluent pump. A copy of the tank details are provided as attachments to this report. The tank(s) should be provided with a heater to prevent freezing. • The tanks must be set level. The excavation bottom must be free of large rocks or other objects that could damage the tank during placement. A gravel road base JOO NO. 114 I V l A C,(VoFt@Ch -5- 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 soil cover depth is 4 feet. • The septic lids must extend to final surface grade and made to be easily located. Sewer Pipe • The sewer line from the structure to the septic tank was also installed in August of 2014 and was inspected by H-P Geotech. As -Built documentation of the sewer line installation will be provided following construction of the remaining portions of the OWTS. Based on our observations the sewer line installation met our minimum specifications, which are provided below. • The sewer pipe 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. • The sewer pipe should be sloped at 2% minimum (no maximum slope) from the residence to the septic tank. The slope of the last 10 feet of sewer pipe should be reduced to between 2% to 4% to help limit disturbance of solids in the tank and potential sewage bypass of the first chamber of the tank. Sewer lines 10 feet or less in length should be sloped between 2% to 4%. • 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. 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'/ 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 the building foundation, where the sewer pipe bends 90 degrees or more and every 100 feet of sewer pipe. Job No. 114 101 A M • 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 is and will be only one sewer line exiting the residence. It is the responsibility of the owner or contractor to locate all sewer line exit locations and connections to the septic tank. We should be notified if there are other sewer lines exiting the building. Effluent Transport Piping • The 1.25 inch diameter Schedule 40 effluent transport piping should be sloped at 2% minimum to drain back from the automatic distribution valve (ADV) to the dose tank and at 2% minimum from the ADV to the trenches. The ADV must be at the high point of the system. • 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 % 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 soil cover 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. Effluent Pumping System • An Orenco PF1005, 115 volt, submersible effluent pump with a 1.25 inch diameter discharge assembly, or equivalent, will be required for effluent pumping. Juo 1VO. 114 IUIH GAVOtech -7- • The maximum effluent transport distance from the pump discharge to the automatic distributing valve (ADV) is estimated to be 155 feet then an additional 38 feet from the ADV to the trenches. • The elevation difference from pump discharge to the dose tank is estimated to be 15 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 10.1 gallons per minute at 23.4 feet of total dynamic head. A pump performance curve is provided as an attachment to this report. • Due to the variability in anticipated flows from the Red Barn, a timed dosing system will be used to help buffer doses to the STA. • At a total design flow of 900 gallons per day and an estimated flow of 10.1 gallons per minute, the pump run time per day must at least 90 minutes. In order to provide sufficient dose volume to fully pressurize the system and to provide for disposal and treatment of 900 gallons per day, we recommend a pump run time of 12 minutes and a rest time of 48 minutes. This will provide dose volumes of approximately 121 gallons per pump run cycle. Actual dose volumes will be about 107 gallons assuming 14 gallons of drainback volume in the effluent transport pipe. In times of non-use or limited use, the system will not dose unless adequate effluent flows are available. • When the effluent level in the dose tank reaches a predetermined level, a liquid level sensor or float switch activates a timer sequence in the control panel. The timer cycles the pump "OFF" and "ON" at the desired dosing intervals until the liquid level drops enough to deactivate the liquid level sensor or float switch. • 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 tank so the transport line can drain after each pumping cycle. quo ivo. 1 14 tVIH GecPtech Automatic Distributing Valve • An Orenco V6403 Automatic Distributing Valve (ADV) will be used to alternate doses to each of the trenches. • The ADV must be installed level and must be the high point in the system. • The ADV should be installed in a sprinkler box, or equivalent, such that it is serviceable and protected from freezing. We recommend the ADV be equipped with heat tape for additional frost protection during winter months. • We recommend the ground surface be graded away from the ADV in all directions. Improper surface drainage could cause standing water to freeze and damage the valve and/or piping. • The valve has clear sections of pipe that should be inspected at least annually to ensure that it is alternating doses to each trench. 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 household drains as this may clog or damage OWTS components. Examples of household waste includes: dental floss, J00 INO. 114 1 U I A G8CRech 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, Biotube 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. • 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 of the septic tank 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 tank. Job No. 114 101 A -10- OWTS CONSTRUCTION OBSERVATION The Eagle County Environmental Health Department requires that the designer of the system provide an As -Built certification of the OWTS construction. We should be provided with at least 48 hour notice prior to the installer needing the As -Built 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 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, percolation test holes, 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. 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 the system permitting.

What is your timing for installation as we're currently slammed and would like to get you the permit for installation within a reasonable time frame. Although this project is pretty simple and straight forward, it will take some little time to get the permit emailed to you, especially since I'm out of town until next Tuesday. The engineered OWTS serving the pavilion will be installed in two phases this year and you'd like to get the tank installed so the facility can be used once constructed before the water features on the property are built in conformance with setback requirements. If my recollection serves me right, you paid $800 for the full permit in anticipation of the completed system. We can craft language in the OWTS permit that will indicate a minimum of 1,000 gallon tank with alarm as to allow the 2,000 tank. Once that aspect of the project is complete, please have Jason inspect the tank installation and alarm system functionality and provide us with a letter and site plan showing the exact location and we will let the building department know that the facility can be occupied although the OWTS permit will remain open for our purposes until the soil https://mail.google.com/mail/ca/?ui=2&ik-I141485fc1&Aew--pt&as frorrpmccordconstruction%40hotmail.com&as_sizeoperator=s_sl&as_sizeunit=s smb&as_... 1/2 6/12/2014 Eagle County Government Mail -RE: Septic Disposal Comments for 12779 Colorado River Rd.

Dear Tom: As requested, Hepworth-Pawlak Geotechnical observed the installation of the Onsite Wastewater Treatment System (OWTS) for the Red Bam structure at the subject property. The OWTS components observed included: sewer piping, septic and dose tanks, effluent transport piping, cleanouts, distribution lateral pipes, Infiltrator chambers, inspection ports, automatic distributing valve, pump, alarm and the locations of these components. This letter summarizes our observations and recommendations. We previously designed the OWTS and presented our recommendations in a report dated April 30, 2015 under the above job number. We performed our As -Built site evaluation on June 5, 2015. The installation and locations of system components and required setbacks were verified as shown on Figure 1 and were surveyed by Archibeque Land Consulting as shown in the attached "Existing Conditions Exhibit" dated July 30, 2015, Job No. 10112. We also performed a pump operation test and verified operation of the automatic distributing valve. It is our opinion that the OWTS was installed in general conformance with our April 30, 2015 design report. Photographs of the OWTS installation are provided in the attached Photograph Log. The observations and recommendations presented above are based on our site observations and our experience in the area.

Hepworth-Pawlak Geotechnical previously conducted a subsoil study for design of foundations at the site and presented our findings in a report dated May 15, 2014, Job No. 114 101A. The existing red barn is planned to be renovated into a pavilion. A 1,000 gallon, two chamber septic disposal tank located to the south (upslope) side of the building is planned as a holding tank until the location of the septic disposal field is determined and the on - site wastewater treatment system (OWTS) can be designed and installed. We have been requested to design the OWTS. Based on our experience with a 1,000 gallon, two chamber tank can likely be used for most typical events and incorporated into the OWTS. For large events, backup septic disposal such as "porta johns" may be needed. The tank should be installed with an alarm system to alert when nearing full. We should observe the tank installation. We will forward our design, when complete. In meantime, if you have any questions or need further assistance, please contact myself or Jason Deem in our Siverthome office.
