There must be room for a backup system in case this experimental system fails. A filter after the final septic tank is required. _ Site of system must be similar to that required for an ET system - not in a shaded north -facing valley, but in an area open to sunshine and breezes enough days per year and hours per day. DETAILS NEEDED IN THE PERMIT Permit must be issued in the name(s) of the legal owners of the property involved and must contain an accurate description of the property Permit must display the requirements in Section 4- 20 of regs, "Experimental Systems". The permit issued for a Drip Irrigation system shall be recorded in real estate records for the property. For 5 years in January of each year, the applicant (owner) must provide a written report to EH Dept.documenting maintenance, soil moisture data if required.. August 10, 1999 ASPEN - PITKIN ENVIRONMENTAL HEALTH DEPARTMENT We have been notified that you are going to install a Drip Irrigation sewage'disposal system for your property and we want to be sure that you, the property owner, understand what this means. This is an alternative method of wastewater disposal not provided for in the Pitkin County Regulations. As such, it has been declared an experimental system and the installation of a total of eighteen such systems have been approved. Attached is a copy of Resolution #99-34 which was adopted by the Pitkin County. Board of Commissioners, acting as the Pitkin County Board of.Health. We request that you read the conditions of the resolution and sign the bottom of this letter stating that you understand these conditions. We have. taken these precautions because Drip Irrigation is an experimental system in this area. Several hundred of these systems have been installed on the Eastern . Slope. However, we do not have historical data to know how the system will perform at this altitude and in the extreme and varying weather conditions we experience. Some conditions that must be met before we can issue your septic permit are as follows: • If a "water balance " method of calculating waste load is applied, a monitoring plan must be submitted to determine saturation status of soils. After installation, you must provide a written report to this Department documenting maintenance on the 'system for a period of five years, and submit it to this Department in Janu. Bch year.

The purpose of the plan is to indicate whether the setbacks from various OWS are within the influence of each other_ The setback for OWS 1 based on the 2712.5 GPD loading is 237 feet. The setback for OWS 2 based on a 3150 GPD loading is 272 feet. Setbacks from the fields are presented on Figure 1. As indicated on Figure 1, the setbacks and therefore zones of influence do not intersect. The systems are therefore considered independent.

The OWS was designed under our Job No. 13288W, dated October 1, 2001. The installation included two 2000 -gallon single -compartment precast concrete septic tanks with dual pumps, a four outlet automatic distributing valve, and four AX20 Advantex"m pods followed by one 1000 - gallon lift station with dual pumps. The drain field consisted of six 12 x 90 feet drip irrigation field sections for a total area of 6480 square feet. ABS pipe was used in the OWS installation. Distribution valves were installed to distribute effluent. The pump, alarm, and filters were in place at the time of our third site visit. The construction manager, Jeff Spalding, with Fenton Construction, may activate pumping system at his discretion. The components of the OWS were installed in conformance with our plans and specifications. If there are questions or if we may be of further service, please ca CHURCH and Associates, Inc. Timothy R.

Ranch, OWS 4 Pitkin County, Colorado Job No. 13288W Mr. Yeary, 2(o q 3 - Z35 4-0 1 —OC4,, This letter is to confirm that there is risk of discharge water treatment backwash to the onsite wastewater system (OWS). Our experience is that the discharge of the backwash brine from a water treatment system can cause an early failure of the field and can affect the treatment process within the AdvanTex system. Based on a telephone conversation with Angela Helliwell of SCG Enterprises, Inc., she indicated one system at Circle R Ranch already has backwash discharge to the AdvanTex system and the treatment process is not functioning properly. Other systems without backwash are functioning properly. Based on telephone conversations with Paul Jacobs and Dean Derosier of McLaughlin Rincon, they are concerned about shallow ground water. It is our understanding there is a "drywell" for the backwash at this time but water ponds. It is suggested the drywell be enlarged. We have also had conversations with Carla Block of the Pitkin County Environmental Health Department (PCEHD) with regard to discharge of water softener backwash. PCEHD does not require a permit for a drywell. PCEHD is aware of problems where water treatment backwash is discharge to OWS. In summary, we strongly advise against discharging backwash from the water treatment system to the OWS. If there needs to be a meeting with respect to this, please call. If there are questions, please call. Sincerely, CHURCH & Associates, a division of InTEC of Denver Metro, LLC. Reviewed by: Edward O.

These figures must replace figures in OWS 1 design and OWS 2 design dated October 15, 2001 and October 1, 2001 respectively. Based on topographic positioning of the irrigation ditches, the mounded drain field and use of Advantex TM secondary treatment with nitrogen reduction, we believe the setback distance can be reduced from 187 feet to 125 feet to down -gradient ditches and to 75 feet to up -gradient ditches. We believe contamination of the ditches by the OWS will be prevented. The temporary water treatment facility meets all required setbacks. The temporary water treatment facility is to be moved further up Woody Creek in 2002. Water lines, when closer than 10 feet to sewer lines, must be sleeved with Schedule 40 HDPE pipe.

ENGINEERS & GEOLOGISTS October 1, 2001 BEACH Environmental LLC 715 West Main, Suite 304 Aspen, Colorado 81611 Subject: Subsurface Investigation and OWS Design TWO MILE RANCH, OWS 2 Pitkin County, Colorado Job No. 13288 Gentlemen, As requested, we have investigated subsurface conditions and prepared an Onsite Wastewater System (OWS) design for the site. Our firm investigated subsurface conditions on September 26, 2001. SITE CONDITIONS The investigated site includes two building envelopes at the Two Mile Ranch as indicated on Figure 1. The subject site is located in a rural area where OWS are required. The slope at the proposed drain field is 5 percent to the northwest. There is a good cover of native grasses at the proposed field location. PROPOSED CONSTRUCTION The sites to be served include two building envelopes, which are 0.6 -acre and 0.7 -acre in size as presented on Figure 1. The average daily sewage load is 1800 gallons per day (GPD) as presented in TABLE I below per Aspen/Pitkin Environmental Health Department (APEHD) regulations. The peak loading is 3150 GPD. There are specific plans for the home at the 0.7 -acre parcel, but no specific plans for the 0.6 - acre parcel. The drain field is proposed to the southeast of the 0.7 -acre building envelope, which will be 212+ feet from Woody Creek The property will be served water by several onsite wells located 272+ feet 7 from the drain field. Water is collected and treated before distribution to individual structures.

HDPE pipe has been substituted for PVC in specifications. In several details we have not changed the PVC description, but we have requested PVC components to be substituted with HDPE. SUBSURFACE CONDITIONS Subsurface conditions were investigated by excavating a test pit and four percolation holes, 26 to 38 inches deep, at the locations indicated on Figure 1. Subsurface materials consisted of 1 foot of silty sand topsoil underlain to 9 feet by reddish brown silty sand with random cobbles. No ground water or bedrock was encountered during the excavation. The percolation test indicates rates from 10 to 27 minutes per inch (MPI). The average percolation rate is 17 NIDI. Percolation data is included as Figure 5. EXPERIMENTAL DRIP IRRIGATION SYSTEM The proposed drip irrigation (wallow trench) OWS has been authorized as an experimental OWS in Pitkin County. As a part of the authorization, there are conditions, which are not typical of other permits in Pitkin County. The conditions include: a. the applicant must commit to follow recommendations of the Department and the design engineer, b. a backup system design is required, c. monitoring of soil saturation and an annual report is required and must be reported for 5 years, d. the site must be reviewed for solar and wind exposure. You will have to agree to the following conditions: 1. you must agree to the terms of the permit; 2. a backup design is an ETA bed design in the same area and 3. monitoring as described later in this letter will be required which will include an annual report as described in Item C. The site has been reviewed as described under Site Conditions and found suitable for installation of a drip -irrigation OWS. Twelve shallow trench drip irrigation systems have been installed and are performing properly in Pitkin County, so we do not anticipate problems with installation or performance ofthe OWS. There are 3500+ successful drip irrigation OWS operating in Colorado. It is our understanding the experimental status of drip irrigation OWS is being reviewed by APEHD staff. We have discussed the status with them and hopefully experimental requirements will not apply to this application. Typically drip irrigation systems are installed where there is poor percolation. Because good percolation rates were found at this site a backup drain field design was not prepared. A backup field could be chamber trenches. RECOMMENDATIONS The results of our investigation indicate an OWS can be installed at` he location presented on Figure 1. The OWS design is based on an average daily sewage load of 1800 GPD with an advanced treatment system and a drip -irrigation drain field. The advanced treatment installation includes two 2000 -gallon (total 4000 gallons), one -compartment concrete septic tanks, with an AdvanTexTm AX20 Treatment System, as presented on Figure 2. Discharge is via a 500 -gallon tank with a pump vault unit (PVU) with dual pumps, as presented on Figures 2 and 4. Pump specifications are included as Figure 3. Similar to a recirculating sand filter, the AdvanTexTM system provides treatment of organics, (total suspended solids and BODS) and nitrate reduction using effluent recirculation through a textile media -filled pods. The AdvanTexTm units treat the effluent before being discharged to the drain field by a dosing -pump. A service contract is recommended for operation and maintenance of the advanced treatment system. W460 OWS 2 Design Job No. 13288 Page 3 Our design includes the installation of 6480 square feet of drip -irrigation field. The drain field installation should include 6480 SF of drip -irrigation field in 6 sections as presented on Figures 1 and 6. The drip irrigation field configuration can be modified to fit the topography with approval of our office. The trenches should be backfilled to re-establish the original slope. The installation is presented with a trencher. The surface of the drip irrigation or ETA field should be seeded after installation of the system. A native seed mix available at seed stores should be used. These mixes do not require irrigation and develop a growth 10 to 15 inches high. No automatic sprinkler system should be installed over the field. INSTALLATION OBSERVATIONS The installation of the OWS is to be observed by the design engineer. We will verify field depth, separation distances and subsurface conditions. The septic tank and AdvanTex1m units are to be installed with risers on the tank, and inlet and outlet connections properly bedded. Other components such as effluent filters or pumping systems, as applicable, will be observed at that time. OPERATION AND MAINTENANCE The AdvanTexTM treatment system is sold as a package that includes component installation and two years of operation and maintenance. We recommend an operation and maintenance contract exist at all times with a certified AdvanTexTM maintenance company. During the first month of operation, the system is to be observed to ensure proper control settings and system "start up". Subsequent to system "start up" a semi-annual observation is to be performed. During the semi-annual observations, septic tank sludge and scum accumulation is to be measured and septage pumping arranged as necessary. The treatment system components are to be cleaned in accordance with the manufacturer's recommendations. Effluent quality is to be observed to confirm a clear, odorless effluent is discharged to the drain field. The dosing system is to be observed to verify its operation. The surface area over the drain field is to be observed for indications of effluent surfacing. Liquid levels in the field are to be measured and recorded. The owner must realize an OWS is different from public sewer service. The owner must be aware of, and assume responsibility for, ongoing maintenance of the system. In the absence of a monitoring program, the septic tank should be pumped every two years. Effluent filter and screened vaults, as applicable, are to be cleaned during pumping. There are daily considerations such as not putting plastic or other nonbiodegradable materials into the septic system. Garbage disposal use should be minimized to reduce the frequency of pumping. Water use must be monitored so toilets are not allowed to run when seals malfunction. To illustrate the point, a flowing toilet can use in excess of 1000 GPD. An additional 1000 GPD loading may flood and irreparably harm the system. We caution against the installation of a water softener. The hydraulic loading from the backwash of a water softener is detrimental to an OWS and a separate drywell should be constructed for the backwash waste, if a softener is installed. No landscaping or plastic can be used over the field, which will reduce performance of the field. Chemically treated water from a swimming pool or spas should not be introduced to the OWS. The design of the OWS is based on the treatment of domestic sewage only. No industrial or hazardous wastes should be introduced into the OWS. Floor drains should not discharge into the OWS. OWS 2 Design Job No. 13288 Page 4 As a part of the experimental permit, there are conditions imposed by the APEHD. The differences from other installations are the requirements for monitoring of the installation of the drip -irrigation system. These may be required because of a prior experience in Pitkin County with experimental systems. Drip -irrigation systems have been installed in Pitkin County and there have been no problems. We anticipate the annual reporting will be a requirement for five years and the cost is estimated to be $200.00 per year if the experimental status is required. LIMITATIONS Our investigation, layout, design, and recommendations are based on data submitted. If conditions dif- ferent from those described in this report are encountered, we should be called to observe the conditions. If proposed constriction is changed, we should be notified to evaluate the effect of the changes on the wastewater system. All construction is to be in accordance with the ISDS regulations.
