A caretaker dwelling unit (CDU) and Free Market Single Family (SF) House are proposed. The property is located outside of Aspen, in an area where OWTS and wells are necessary. SITE CONDITIONS The property is currently developed; however, the existing structures on the property will be demolished prior to construction of the new residences. Water to residences will be provided by a private well. SUBSURFACE CDU: The subsurface was investigated by digging three profile pits and two sets of three percolation holes, as indicated. Profile #1 and the associated percolation holes are closest to the proposed absorption area that will serve the CDU. The materials encountered in the profile pit #1 consisted of 1.0 -foot of a sandy, gravelly root zone, underlain by sandy, clayey, gravelly, very dense, moist red/brown/tan soil to the maximum depth explored of 8 feet. No groundwater or bedrock was encountered, but excavation was difficult. A gradation was performed on profile pit #2 resulting in 14% gravel, 51% sand, and 35% fines. See Tables 1, 2, and gradation analysis for details. Free Market SF House — Parcel A: The subsurface was investigated by digging three profile pits and two sets of three percolation holes, as indicated. Profile #3 and the associated percolation holes are closest to the proposed absorption area that will serve the 2 -bedroom Free Market SF house on Parcel A and the Free Market SF house on Parcel B. The materials encountered in profile pit #3 consisted of C Page 2 1.0 -foot of sand with cobbles and gravel, underlain by sand, clayey, gravelly, very dense, moist red/brown/tan soil to the maximum depth explored of 8 feet. No groundwater or bedrock was encountered, but excavation was difficult. An average of 30 MPI percolation rate will be used to design the OWTS. See Tables 1, 2, soil log, and gradation analysis for details. DESIGN SPECIFICATIONS CDU: The OWTS serving the CDU will be designed to serve 1 -bedroom. An average daily wastewater flow of 150 GPD will be used. The installation must include a 1000 -gallon, two-compartment septic tank with an effluent filter. Effluent will be gravity fed to two gravelless chamber beds consisting of 2 rows of 8 Quick 4 chambers, for a total of 32 chambers, or one graveness chamber bed consisting of 3 rows of 9 ARC 36 chambers for a total of 27 chambers. Free Market SF House — Parcel A: A 1000 -gallon, two-compartment septic tank with a Biotube pump vault will serve the Free Market SF House on Parcel A. A P-30 pump and standard control panel are recommended. The absorption area will be sized to accommodate flow from both the Free Market SF House on Parcel B (5 bedrooms with living area greater than 6000 square feet) and the Free Market SF House on Parcel A (2 bedrooms). An average daily wastewater flow of 1300 GPD will be used to size the absorption area which will consist of a level 6" deep sand bed, 33 -feet wide by 54 -feet long. 72 Eljen modules will be placed on the bed, 6 rows of 12 modules, with 3 -feet of space between each row. Depth of cover over modules should be between 12" and 24". Construction must be according to Pitkin County OWTS Regulations, the OWTS Construction Permit provided by Pitkin County Environmental Health Department, and this design. OPERATION INFORMATION AND MAINTENANCE The surface of the drain field should be seeded upon completion. Vegetation is an important factor in drain field performance. Erosion control should be practiced prior to and during re -vegetation. No heavy equipment, machinery, or materials should be placed on backfilled drain field. Livestock should not graze on the drain field. Plumbing fixtures should be checked to ensure that no additional water is being discharged to OWTS. For example, a running toilet or leaky faucet can discharge hundreds of gallons of water a day and harm a drain field. The homeowner should pump the septic tank every two years, or as needed gauged by measurement of solids in the tank. The effluent filter should be cleaned annually, or as needed. Garbage disposal use should be minimized, and non -biodegradable materials should not be placed into the OWTS. Grease should not be placed in household drains. Loading from a water softener should not be discharged into the OWTS. No hazardous wastes should be directed into the OWTS. Mechanical room drains should not discharge into the OWTS. The OWTS is engineered for domestic waste only. ADDITIONAL CONSTRUCTION NOTES If design includes a pump, air release valves and weep holes should be installed to allow pump lines to drain to minimize risk of freezing. Excavation equipment must not drive in excavation of drain Page 3 Id due to the potential to compact soil. Extensions should be placed on all septic tank components allow access to them from existing grade. Precast concrete tanks and distribution boxes should be -d, unless plastic or fiberglass is required. Access to all tank compartments and distribution devices optimal. INSTALLATION OBSERVATIONS ALL SERVICE septic, LLC must view the OWTS during construction. The OWTS observation should be performed before backfill, after placement of OWTS components. Septic tanks, distribution devices, pumps, dosing siphons, and other plumbing, as applicable, must also be observed. ALL SERVICE septic, LLC should be notified 48 hours in advance to observe the installation. LIMITS: The design is based on information submitted. If soil conditions encountered are different from conditions described in report, ALL SERVICE septic, LLC should be notified. All OWTS construction must be according to the county regulations. Requirements not specified in this report must follow applicable county regulations. The installer should have documented and demonstrated knowledge of the requirements and regulations of the county in which they are working. Please call with questions.

Aspen Earthmoving installed the system. The installation included a new 1000 -gallon, two-compartment Valley Precast concrete septic tank with a Biotube® Pump Vault and pump in the second compartment. The filter in this compartment must be cleaned annually, or as needed. The location of the tank was moved closer to field because of groundwater issues near the foundation of the CDU. Effluent is pumped to two gravelless chamber beds, each with two rows of 8 `Quick 4' chambers in each bed for a total of 316 square feet of infiltrative area. The field installation was shallow, no more than 2 - feet below native grade, to assure at least 4 -feet separation between the infiltrative area and seasonal high groundwater. The OWTS was generally installed according to specifications. This observation is not a guarantee of workmanship and/or parts and materials. ALL SERVICE septic, LLC should be notified if changes are made to the OWTS in the future. Any additional OWTS construction must be according to the county regulations. LIMITS: Observations are limited to components that are visible at the time of the inspection. The installer must have documented and demonstrated knowledge of the requirements and regulations of the county in which they are working. The quality of the installation is dependent of the expertise of the installer, soil type, and weather conditions. Please call with questions.

On July 18, 2013 a site visit was conducted and the pipe in Profile #1 was still present and no groundwater was observed. An additional profile hole was excavated and groundwater was present at approximately 7 - feet. An estimate of groundwater at 6 -feet will be used for this design. DESIGN SPECIFICATIONS CDU: The OWTS serving the CDU will be designed to serve 1 -bedroom. An average daily wastewater flow of 150 GPD will be used. The installation must include a 1000 -gallon, two-compartment septic tank with an Orenco® pump and Biotube® pump vault in the second compartment. A minimum 2" line must be run from the tank to the manifold. There must be a high point for adequate drain -back after each pump cycle and a weep hole in the line before it exits the tank. The pump line should be well bedded to avoid any settling. Effluent will be pumped to two gravelless chamber beds consisting of 2 rows of 8 Quick 4 chambers, for a total of 32 chambers, OR one gravelless chamber bed consisting of 3 rows of 9 ARC 36 chambers for a total of 27 chambers. Installation of the chambers may not be more than 2 -feet below grade and there must be at least 1 -foot of cover over the chambers. This letter and attached pump specification should be used in conjunction with the design letter and drawings dated October 8, 2012. This letter should be submitted to Pitkin County Environmental Health Department. Construction must be according to Pitkin County OWTS Regulations, the OWTS Construction Permit provided by Pitkin County Environmental Health Department, and this design. OPERATION INFORMATION AND MAINTENANCE The surface of the drain field should be seeded upon completion. Vegetation is an important factor in drain field performance. Erosion control should be practiced prior to and during re -vegetation. No heavy equipment, machinery, or materials should be placed on backfilled drain field. Livestock should not graze on the drain field. Plumbing fixtures should be checked to ensure that no additional C • Page 2 water is being discharged to OWTS. For example, a running toilet or leaky faucet can discharge hundreds of gallons of water a day and harm a drain field. The homeowner should pump the septic tank every two years, or as needed gauged by measurement of solids in the tank. The effluent filter should be cleaned annually, or as needed. Garbage disposal use should be minimized, and non -biodegradable materials should not be placed into the OWTS. Grease should not be placed in household drains. Loading from a water softener should not be discharged into the OWTS. No hazardous wastes should be directed into the OWTS. Mechanical room drains should not discharge into the OWTS. The OWTS is engineered for domestic waste only. ADDITIONAL CONSTRUCTION NOTES If design includes a pump, air release valves and weep holes should be installed to allow pump lines to drain to minimize risk of freezing. Excavation equipment must not drive in excavation of drain field due to the potential to compact soil. Extensions should be placed on all septic tank components to allow access to them from existing grade. Precast concrete tanks and distribution boxes should be used, unless plastic or fiberglass is required. Access to all tank compartments and distribution devices is optimal. INSTALLATION OBSERVATIONS ALL SERVICE septic, LLC must view the OWTS during construction. The OWTS observation should be performed before backfill, after placement of OWTS components. Septic tanks, distribution devices, pumps, dosing siphons, and other plumbing, as applicable, must also be observed. ALL SERVICE septic, LLC should be notified 48 hours in advance to observe the installation. LIMITS: The design is based on information submitted. If soil conditions encountered are different from conditions described in report, ALL SERVICE septic, LLC should be notified. All OWTS construction must be according to the county regulations. Requirements not specified in this report must follow applicable county regulations. The installer should have documented and demonstrated knowledge of the requirements and regulations of the county in which they are working. Please call with questions.
