The property is located outside of Basalt, in an area where OW TSs and wells are necessary. The legal description of the property is Lot 20, Mountain Meadow Ranch, Second Filing, according to the plat thereof recorded August 3, 1979 in Book 289 at Page 266 as reception No. 185666, County of Eagle, State of Colorado. SITE CONDITIONS A 3-bedroom, single-family residence presently exists and is utilizing an existing OWTS. A remodel is proposed and a bedroom will be added. The existing OWTS consists of one 1000-gallon, two- compartment concrete septic tank and a 700 square foot pipe and gravel soil treatment area (STA). Eagle County Environmental Health Department Individual Sewage Disposal System (ISDS) Permit 669 documents this system. The percolation rate is documented as 10 minutes per inch (MPI) and was sized to accommodate a 3-bedroom residence. The system was given final approval by Eagle County on November 21, 1984. The existing OWTS was inspected by CBO, Inc. on February 26 & 28, 2014 and was found to be functioning normally with no signs of surface saturation or failure (report enclosed). The residence is served by a private well, which is located greater than 50-feet from the proposed and existing septic tank and greater than 100-feet from the existing STA. SUBSURFACE The subsurface was investigated on April 28, 2015 by digging two soil profile test pit excavations (Test Pits). A visual and tactile soil analysis was completed by Carla Ostberg at the time of excavation.1 The materials encountered in the Test Pit #1 consisted of dark to medium brown, moist, topsoil to 18- inches, underlain by tan to white loamy sand (caliche) with angular basalt boulders to a maximum depth explored to 7.5-feet. No bedrock or groundwater was encountered. 1 Carla Ostberg holds a Certificate of Attendance and Examination from the CPOW Visual and Tactile Evaluation of Soils Training. Page 2 The materials encountered in Test Pit #2 consisted of dark brown, moist, topsoil to 18-inches, underlain by tan to white loamy sand (caliche) with angular basalt boulders to a maximum depth explored of 3.5- feet. There was backhoe refusal in this pit at 3.5-feet on a large boulder. No bedrock or groundwater was encountered. A tactile analysis was taken from the soil at approximately 3 to 4-feet below grade. The sample was sieved and the soil formed a ball but no ribbon. The soil structure shape granular with very fine grains, had moderate structure grade, and loose consistence. STA sizing is based on Soil Type 1, Loamy Sand. This is consistent with the Eagle County Environmental Health Department percolation testing report dated 8/21/84 with an average percolation rate of 10 MPI and soil type reported as Silt/ Sand / Volcanic Rock. A long term acceptance rate (LTAR) of 0.8 gallons per square foot will be used to determine minimum sizing criteria of the STA, in accordance with Table 10-1 Soil Type 1 presented in the Eagle County On-Site Wastewater Treatment System Regulations, adopted May 13, 2014. Test Pits observed April 28, 2015 Test Pit #1 Test Pit Backfill Sieved sample Test Pit #2 Test Pit only dug to 3.5-feet (backhoe refusal) Page 3 DESIGN SPECIFICATIONS The OWTS design is based on 4-bedrooms. An average daily wastewater flow of 600 GPD will be used. We are proposing an alternating system to allow continued use of the existing STA2. Design Calculations: 600 GPD x 48 hour retention time = 1200 gallons minimum septic tank capacity Existing STA (pipe and gravel) 600 GPD / 0.8 gallons / SF = 750 SF 750 SF x 1.2 (gravity bed) x 1.0 (pipe and gravel) = 900 SF minimum STA 50% of 900 SF = 450 SF Existing 700 SF > required 450 SF Proposed additional STA (chamber bed) 600 GPD / 0.8 gallons / SF = 750 SF 750 SF x 1.2 (gravity bed) x 0.7 (chambers) = 630 SF 50% of 630 SF = 315 SF Minimum 27 ‘Quick 4’ Infiltrator® chambers The existing septic tank will be properly abandoned in place. The septic tank must pumped and collapsed and remaining void filled with gravel, sand, or compacted soil. A new minimum 1250-gallon, two-compartment concrete septic tank will be installed. An effluent filter (or screen) must be installed on the outlet tee of the septic tank. A Bull Run valve must be installed on the 4-inch pipe exiting the septic tank, connecting both the existing and new STAs. This Bull Run valve must be accessible from grade. The valve must be rotated annually, allowing each STA resting. Rotation of the valve should be documented by the homeowner and records maintained for future reference. The existing STA consists of 700 square feet of pipe and gravel infiltrative area. An inspection port is present at the end of the STA and must remain. This inspection port may be cut to grade and covered with a valve box for access. If the pipe from the Bull Run valve to the existing STA is found to have an accumulation of sludge, we recommend jetting this line. We also recommend removal of the existing garden area above the existing STA. The new STA will consist of three rows of 9 ‘Quick 4’ Infiltrator® chambers, connected with a level manifold, for a total of 27 chambers and 324 square feet of infiltrative area. The chambers should be placed between 2 and 3-feet below native grade. Inspection ports should be placed at the four corners of the bed and may be cut to grade and covered with a valve box for access. The component manufacturers are typical of applications used by contractors and engineers in this area. Alternatives may be considered or recommended by contacting our office. Construction must be according to Eagle County On-Site Wastewater Treatment System Regulations, the OWTS Permit provided by Eagle County Environmental Health Department, and this design. 2 Onsite Wastewater Treatment System Regulation #43, Section 43.10 F. 1. Page 4 REVEGETATION REQUIREMENTS An adequate layer of good quality topsoil capable of supporting revegetation shall be placed over the entire disturbed area of the OWTS installation. A mixture of native grass seed that has good soil stabilizing characteristics (but without taproots), provides a maximum transpiration rate, and competes well with successional species. No trees or shrubs, or any vegetation requiring regular irritation shall be placed over the area. Until vegetation is reestablished, erosion and sediment control measures shall be implemented and maintained on site. The owner of the OWTS shall be responsible for maintaining proper vegetation cover. OPERATION INFORMATION AND MAINTENANCE The property owner shall be responsible for the operation and maintenance of each OWTS servicing the property. The property owner is responsible for maintaining service contracts for manufactured units, alternating STAs, and any other components needing maintenance. Geo-fabrics or plastics should not be used over the STA. No heavy equipment, machinery, or materials should be placed on the backfilled STA. Livestock should not graze on the STA. 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 STA. The homeowner should pump the septic tank every two years, or as needed gauged by measurement of solids in the tank. 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 must be installed to allow pump lines to drain to minimize risk of freezing. The pump shall have an audible and visual alarm notification in the event of excessively high water conditions and shall be connected to a control breaker separate from the high water alarm breaker and from any other control system circuits. The pump system shall have a switch so the pump can be manually operated. Excavation equipment must not drive in excavation of the STA due to the potential to compact soil. Extensions should be placed on all septic tank components to allow access to them from existing grade. Backfill over the STA must be uniform and granular with no material greater than minus 3-inch. 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 contractor should have documented and demonstrated knowledge of the requirements and regulations of the county in which they are working. Licensing of Systems Contractors may be required by county regulation. Page 5 Please call with questions.

The subject OWTS consists of one 1000-gallon, two-compartment concrete septic tank and a 700 square foot pipe and gravel system. Eagle County Environmental Health Department Individual Sewage Disposal System (ISDS) Permit 669 documents this system. The percolation rate is documented as 10 minutes per inch (MPI) and was sized to accommodate a 3-bedroom residence. The system was given final approval by Eagle County on November 21, 1984. Access to the septic tank manhole lids were approximately 4 to 6-inches below grade. The septic tank appeared to be in good condition. Both inlet and outlet tees were present. The septic tank was pumped in August 2013 by B&R Septic. Water levels in the septic tank appeared normal. Pumping is not necessary at this time. We recommend installation of an effluent filter on the outlet tee of the septic tank. The absorption area appeared to be under a fenced in garden. One observation port was present on the west end of the observation area and was dry at the time of the inspection. According to Eagle County documents, the absorption area is pipe and gravel. We do not recommend continuing a garden above the absorption area. Attached is a fact sheet regarding septic systems from the University of Nevada Cooperative Extension. Please note the section titled “Can I plant a vegetable garden over a leach field?” At the time of the inspection, the residence was vacant and the absorption area was covered with snow; however, there was no indication of saturation or failure. Recommendations:  Add effluent filter to outlet tee (see attached specification sheet). We recommend the Orenco® 4-inch Biotube Jr. This filter should be cleaned annually.  Pump septic tank as needed, as gauged by accumulation of solids. This evaluation is not a guarantee of future system performance. Please call with questions.
