The mailing address is 130 South Galena, Aspen, Colorado, 81611. Any questions concerning your septic system permit will be answered in a timely matter. A building lot must comply with three broad requirements before the permit of a conventional system can be issued. These requirements are. as follows: 1. satisfactory soil percolation test, 2. satisfactory soil profile test hole, 3. and minimum setback distance requirements (as provided in this packet) Soil Percolation Test The percolation (perc) test enables the Environmental Health Department to determine the capacity of the soil to adsorb liquids. This provides the standards for sizing a leach field. Perc tests must be certified by a professional engineer registered by the State of Colorado. Homeowners and contractors are prohibited by Colorado Law from conducting these tests themselves. When the perc tests are conducted by a Registered Professional Engineer, the results must be submitted on the same format as the attached form and properly signed and stamped with an Engineer's seal. Percolation tests must be run in at least three holes inside the proposed leach field area. These holes need to be staked and numbered for easy identification. The perc test holes must be at the same depth as the proposed leach field; if the site is on a hillside the uphill holes must be deeper than the downhill holes. See Figure 3 for a description of perc test holes. Perc test holes must be pre-soaked, filled with water several times, for a minimum of eight hours prior to running the test. Pre-soaking is vital to obtaining accurate results in the percolation test. Soil Profile Hole The soil profile test hole enables the Environmental Health Department to determine if groundwater, bedrock, impervious clay layers, etc., exist in the area of the proposed leach field. These conditions may cause problems with the functioning of the leach field. If any conditions do exist that may interfere with a conventional system, an engineered design system may be required. The soil profile hole is a large hole eight feet deep and is usually dug with a backhoe. This hole must be properly barricaded immediately after it is excavated to prevent accidents. 1 130 South Galena Street Aspen, Colorado 81611 303/920-5070 The soil profile hole must meet the following requirements: 1. It must be at least eight feet deep, or to bedrock, but at least four feet deeper than the proposed leach field. 2. It must be large enough in diameter to permit visual observation of the soil strata at all levels. 3. It must be located not closer than four feet nor farther than ten feet from the proposed leach field. This test hole must be inspected by Aspen/Pitkin Environmental Health Department personnel. Soil logs developed by qualified soil engineers will be accepted in lieu of this inspection if the Department has given approval. Some portions of Pitkin County exhibit seasonally high water tables. In these areas the Environmental Health Department inspection can only be made during maximum groundwater level periods (usually May 15th through June 15th). If inspections are made in these areas at other times of the year, a system may be installed that will not function property. Please contact the Environmental Health Department if you believe there is a high water table on the building site. Minimum Distance Requirements Individual sewage disposal system components must be adequately separated from water supplies, streams, buildings, property lines, etc. to prevent contamination, building settling, and other potential problems. These distances are located in Table 2. Site Inspections The Aspen/Pitkin Environmental Health Department makes at least two site inspections (initial site inspection and final inspection) on each individual sewage disposal system. These inspections are described in detail later. If a specific system were to require more inspections, arrangements should be made in advance with this Department. Initial Site Inspection: Initial site inspections enable the Department to determine if a conventional system will function properly on a building site. This inspection must be done prior to issuing an ISDS permit. Before requesting an initial site inspection, the following must be completed: 1. soil percolation tests certified by a registered professional engineer, 2. a soil profile hole must be excavated and available for inspection by Department staff, 3. all components of the system as well as proposed buildings, wells, water lines, and property lines must be staked out on the property, 4. and the Department must have a copy of the competed application and all fees must be paid. Arrangements for initial site inspections should be made at least two working days in advance of the requested inspection time. Final Inspection: Final inspections enable the Environmental Health Department to determine if the components of the system are properly installed and if the permit conditions have been met. Before requesting a final inspection the following conditions must exist: 1. The individual sewage disposal system must be completely installed. If the Department must make more than one final inspection because the system was not completely installed, charges may be made for extra inspection fees. All fees are outlined in Table 1. If a phased inspection schedule is necessary, however, no additional charges will be made if arrangements have been made- in advance with the Environmental Health Department, 2. All components of the system must be exposed so that they may be inspected. Do not backfill any portion of the system prior to final inspection. Arrangements for final inspections should be made at least two working days in advance of the requested inspection time to allow for the most efficient planning. Problem Sftuations Several conditions may prohibit the installation of a conventional sewage disposal system or require the system to be designed by a registered professional engineer. These conditions include but are not limited to the following: 1. unsatisfactory soil perc results (either too fast or too slow), 2. high groundwater table, 3. insufficient depth of suitable soil, 4. minimum distance requirements cannot be met, 5. or slopes in excess of thirty percent (30%). If any of these conditions exist an engineer designed system must be submitted to the Department stamped with a certified engineers seal. A final letter stating that the system was constructed according to design must also be submitted by the engineer after the system is complete. Please contact the Department for information on alternative systems or possible solutions which may be available. Septic Tanks and Dosing Systems Septic tanks are usually constructed of concrete, fiberglass, or plastic. Each material has advantages and disadvantages. The Environmental Health Department or hired contractor can outline the specifics of each. Metal is not an acceptable material for septic tank construction as it corrodes easily. The minimum septic tank size allowed in Pitkin County is seven hundred and fifty (750) gallons. All tanks must have two compartments. Each compartment must have a manhole with a diameter of at least twenty (20) inches allowing access into it. This is an important item for the maintenance of the tank. Passive or active dosing systems allow sewage to flow into the leach field during intervals throughout the day. This periodic dosing of the leach field has shown to extend the life of the field and provide better distribution of the entire field area. The Environmental Health Department recommends the use of these devices where possible. Maintenance of an ISDS Home owners should exercise care in how they use their individual sewage disposal systems. Solid material (particularly from the garbage disposal) should be kept to a minimum. With periodic maintenance and reasonable use the septic system should last a long time. Septic Tanks: The primary function of a septic tank is to remove solids from the sewage. This is a primarily physical process of settling, although some biological decomposition does occur. The solids that accumulate in the tank need to be removed periodically or they will be carried into the leach field and cause possible malfunction. Septic tanks should be checked annually to determine the volume of solids in the tank. To facilitate this process, Pitkin County regulations require that tank lids be no deeper than the ground surface on all recently constructed systems. Since 1973 the Department has made drawings of each system as 3 it was installed. These drawings are on file and can be made available upon request for assistance in locating septic tanks and fields. A nominal fee must be charged for such copies. Actual inspection of solids accumulation is the only way to determine if the tank needs to be pumped. The septic tank must first be located and the lid of the first compartment removed. A layer of grease and scum will be floating on top of the water in the tank. This is a normal situation. The grease layer is fairly resistant to penetration but a hole must be made for access to the water below. To check the solids accumulation a long stick with rough white cloth attached to it is lowered into the first compartment of the tank until contact is made with the tank bottom (Figure 1). Solids will adhere to the white cloth and the depth can be measured once the stick is removed. When the depth of the solids is 50% of the water depth in the tank, the tank should be pumped. An alternative to this process is to pump the tank every year or every two years. This ensures that solids are not accumulating. Prior to pumping, make sure both compartment lids are uncovered and to have both compartments pumped. Absorption Fields: The primary function of an absorption field is to evenly distribute septic tank effluent through an area of soil that will filter the sewage water as it moves through the soil. Most conventional leach field require no maintenance. Occasionally, even with proper installations and septic tank maintenance, leach fields will fail to work properly. Commonly this is due to a biological clogging layer that is formed with the use of a system over a period of time. When this situation occurs, sewage will either back up into the house or be discharged onto the surface of the ground. In the past a malfunctioning leach field required the installation of a new system. Recent technological developments now make it possible to treat some systems which are malfunctioning or to do simple repair work to the system. Please contact a contractor or this Department for information on failing systems. The Application Process The ISDS application gives the Department information about the house to be built. From this data it can be determined where the property is and how much sewage might be produced from the home on a daily basis. Graph paper can be used for the site plan if desired. This site plan enables the Department to determine if any minimum distance problems exist before time is devoted to a site inspection. The contractor will also use this information to construct the system. A sample plot plan is included in this package (Figure 2). The sample shows the type of information and the detail needed on the plat plan and is included on the application. Also included is Table 2 showing minimum setback distances. Tables 3, 4, and 5 are included for additional information on sizing tanks and fields. The Soil Data Form is attached for the soil percolation results. Please make sure the engineer stamps this page with a registered seal. Please make sure that the application has been filled out completely and all requested information is provided. Incomplete applications can not be processed and will cause a delay in the issuing of an ISDS permit. TCPC: W P:PERM(T.D.APP.INFO.ISDS 4 Table 1.

EOC i daft J E.O. CHURCH, INC. ENGINEERS & GEOLOGISTS F April 24, 1995 / ' Michael Gassman, Architect / P.O. BOX 740 Aspen, CO 81612 Subject: Onsite Sewage Disposal System Design Proposed Sultani Residence, 350 Upper Ranch Road Lot 7, Filing 2, Brush Creek Village Pitkin County, Colorado Job No. 6076 Dear Mr. Gassman, As requested, we have visited the site, evaluated subsurface condi- tions and prepared an onsite sewage disposal system (OSDS) design for the subject site. The design is based on a review of plans, test pits for subsurface condition evaluation by Nelson Environmental & Waste- water Solutions, Ltd.. We met with Bob Nelson on April 14, 1995 at the site. SITE CONDITIONS - The site is an approximate 2 acre lot located in a developing rural subdivision of Pitkin County, Colorado as indicated on Fig. 1. At the time of our design a single family residence was proposed in the southwestern portion of the lot. The slope at the proposed field ranges from 40 to 550 to the east-northeast. The site was vacant at the time of our design. The site has a sparse cover of native grass and with a moderate cover of sage brush and service berry in the proposed disposal field area. PROPOSED CONSTRUCTION - The location of the proposed residence and disposal field are presented on Fig. 1. The sewage load for a 4 bed- room dwelling is 600 gallons per day (GPD), 900 GPD with a 1.5 safety factor. This loading includes a garbage grinder and washing machines. Water will be provided by the Snowmass Water and Sanitation District. SUBSURFACE CONDITIONS - Subsurface conditions were investigated by Nelson Environmental & Wastewater Solutions, Ltd. by excavating two hand dug profile pits and percolation holes in the proposed field areas indicated on Fig. 1. Subsurface conditions consisted of 3 feet of stiff sandy clay underlain by weathered claystone. No free water was encountered, although snowmelt was infiltrating the near surface soil. Percolation test could not be performed because of the snow - melt. Samples were obtained from each profile hole and gradation tests were performed as indicated on Fig. 5. The results of our evaluation of subsurface conditions and the gradation analysis indicates a perco- lation rate of 180 minutes per inch (MPI). RECOMMENDATIONS - We recommend a low pressure shallow trench OSDS be installed in the natural soils. We recommend the OSDS be designed based on a percolation rate of 180 MPI, which is an application rate 925 East 17th Avenue • Denver, Colorado 80218.1407 P.O. Box 2869 • Evergreen, c;oioraao tlu4J`J (303) 832.9692 FAX (303) 832.3517 (303) 674-0660 FAX (303) 674-0813 of 0.18 gallons/square-foot/day (GAL/SF DAY). This application rate utilizes slow rate soil absorption an evapotranspiration. The OSDS should be designed for a sewage load f 600 GPD. A low pressure shal- low trench disposal system design ba ed on an application rate of 0.18 GAL/SF/DAY and a sewage load oGPD is presented on Figs. 1 - 4. In lieu of a pump, a dosingLsipho can be installed as long as the siphon will deliver a minimum of 200 gallons per dose. As indicated on Fig. 1, the field has an area of 7200 square feet«--�& Sec- tions. There are 3 valves from which there ares iribution bow to __ divide flow to the 6 sections. The dispersal lines ___._ r are to be installed at the outside edges of backhoe trenches. The trenches must be level within each of the 6 sections. We recommend 1 of the sections be closed at a time, and the closure be rotated on a six month basis to allow periodic drying of each section of field. The location of the fields will be staked by Bob Nelson. Two sections are to be located above a cedar tree and the remaining 4 sections are to be located on a slightly flatter area on the lower portions of the lot. If the owner is anticipating finishing of additional bedrooms in un- finished areas, we recommend the OSDS be constructed to handle the ad- ditional loading. The installation of a properly sized OSDS to serve future buildout can be cost effective. The proposed septic tank con- figuration will serve up to a 5 bedroom residence. For greater than 5 bedrooms, either or both the septic tanks can be upsized to 1250 gallons to accommodate t 7 edrooms. Each additional bedroom would require an additional 180 r of disposal field. We recommend the surface of the disptx field be seeded after instal- lation of the low pressure shallow trench system. We recommend using a seed mix such as a "Foothills, Pasture, or Prairie" mixes available at local seed stores. These mixes do not require irrigation and devel- op a growth 10 to 15 inches high. No automatic sprinkler system should be installed over the disposal field. The owner must realize an OSDS is different from public sewer service. The owner must be aware of and assume the responsibility for mainte- nance of the system. The system is relatively maintenance free, but the owner must have the septic tanks pumped. We recommend the trash chambers (1st tank) be pumped at the end of the lst year of use to monitor sludge buildup and every 2 years afterwards. There are daily considerations, such as not putting plastic or other nonbiodegradable material down the OSDS. Water use must be monitored so toilets are not allowed to run when seals malfunction. To illustrate the point, a running toilet will use in excess of 1000 GPD if allowed to run. An excess 1000 GPD will irreparably harm the system. We caution you against installation of a water softener. The hydrau- lic loading from the backwash of a water softener is detrimental to OSDS and a separate drywell should be constructed for the backwash waste, if a water softener is installed. No landscaping or plastic can be used over the disposal field, which will reduce performance of the disposal field. Chemically treated water from a swimming pool or spas must not be introduced into the OSDS. LIMITATIONS - A low pressure shallow trench design requires installa- tion by a contractor who is experienced or has close supervision dur- ing installation. We have worked with Nelson Environmental previously and would anticipate having them supervise installation. Our layout, + � 3 design and recommendations are based on data submitted. If subsurface conditions considerably different from those described in this report are encountered, we should be notified to evaluate the affect of the changes on the proposed sewage disposal system. If modifications to this design are made by governing Health Departments, we should be contacted to evaluate the impact of the changes on the performance of our OSDS design. If there are any questions, or if we can be of further service, please call. E. 0. CHURCH, INC,,, Edward 0. Church r _ Pe.
