Any changes must be approved by this department and the design engineer prior to them being made. Per Pitkin County policy an ISDS for a barn is sized based on one horse per stall and 50 gallons of water usage per wash. The engineer design includes 275 gallons per day for the horse wash; therefore there can be five horses/stalls in the barn. The design is sized to include a potential attached living unit of less than 2,000 sq. ft. with no more than 2 bedrooms. The design has one 1500 gallon two compartment concrete tank with pump in biotube vault. There is a 30% reduction for use of infiltrators.The design is for a bed, 3 chambers wide by 16 chambers long = 48 units. Minimum horizontal distances between components of the system and physical features shall conform to the Pitkin County ISDS regulations. Permit approved by::zu.

ENGINEERS & GEOLOGISTS August 26, 1999 Julie Wykoff 42705 East Highway 82 Aspen, CO 81611 Subject: Revised OWS Design, Proposed Goodman/Bonini Barn 6548 Snowmass Creek Road, Snowmass, Sections 22 and 23, T9S, R68W, 6' P.M. Pitkin County, Colorado Job No. 10575-A Dear Ms. Goodman and Mr. Bonini, As requested, we are providing this revision of our OWS design for the subject site. The revision is based on the additional loading of a horse wash to be located nest to the proposed barn from our May 17, 1999 design letter. This letter should be used in conjunction with our original design letter. This letter includes two revised figures., Figures 1 and 2, and a pump curve diagram. The original Figures 1 and 2, and the pump curve, should be removed to reduce confusion. SITE CONDITIONS - The barn site is located in a rural area in Pitkin County, Colorado. The proposed drain field area has a moderate slope. There is a moderate cover of grasses, sagebrush, and scrub oak at the proposed field. PROPOSED CONSTRUCTION — The proposed barn will contain a one -bedroom residence with 1'/2 bathrooms and a horse wash. The living area will be less than 2000 square feet (SF). We proposed to design the OWS on two bedrooms and 275 gallons per day for the horse wash. The average sewage loading for a two-bedroom residence is 300 gallons per day (GPD) using Aspen/Pitkin Environmental Health Depart- mentEHD) loading of 75 gallons per day per person. The sewage loading with a peaking factor of 1.75 D n is 10 6 GPD. This loading includes a dishwasher, garbage grinder, and washing machine. The barn is served water by a well, which is greater than 102 feet from the proposed drain field. There is a pond near the river. The drain field must be greater than 50 feet from the pond. There is an irrigation ditch to the west and above the proposed field area. It is proposed to line the line within 50 feet of the proposed field. SUBSURFACE CONDITIONS - A subsurface investigation was performed by drilling seven percolation holes, 27 to 40 inches deep, and one profile hole. Subsurface conditions encountered in the profile hole consist of 1 foot of rich topsoil, underlain to the maximum depth explored of 8 feet by silty sand with gravel and cobbles. Percolation tests indicate percolation rates of 8 to 40 minutes per inch (MPI). The average percolation rate is 26 MPI. No groundwater or bedrock was encountered. RECOMMENDATIONS - We recommend the installation of a septic tank, pump, and one gravelless chamber bed. The OWS design is based on an average se�ge load of 575 GPD and a percolation rate of 26 MPI. We recommend the installation of a 1500 -gallon two-compartment concrete septic tank with a pub in a biotube vault. A pump is required duefo e evation differences and to increase the efficiency of the field. We recommend a pump with 25 gallons per minute flow rate and 33.7 feet of head be installed. The floats should be set to pump 250 gallons. Pump details are presented as Figure 3 and the pump curve. The drain field should consist of one 100 -feet by 9 -feet gravelless chamber bed be installed, as indicated on DENVER 4501 Wadsworth Boulevard Wheat Ridge, CO 80033 CASTLE ROCK 303.660.4358 303.463.9317 Fax: 303.463.9321 EVERGREEN 303.816.1455 Revised OWS Design, Barn/Caretaker Unit Job No. 10575-A Page 2 Figure 1. The bed requires 3 rows of 16 chambers. The drain field should be constructed similar to Figures 1 and 2. If additional bedrooms are possible, we recommend the OWS be constructed to serve the additional loading. This OWS design will serve a two-bedroom residence less than 2000 SF. For greater than two - bedrooms, the septic tank can be upsized 328 gallons for each additional bedroom. Each additional bed- room would require an additional 188 SF of field or 13 gravelless chambers and require a new permit. We recommend the surface of the field be seeded after installation of the field using a native seed mix. These mixes do not require irrigation and develop a growth 10 to 15 inches high. No automatic sprinkler system should be installed over the fields. No landscaping or plastic can be installed over the field, which will reduce performance of the fields. Livestock should not be confined in the field area. OPERATION AND MAINTENANCE - The owner must realize an OWS is different from public sewer service, and must assume the responsibility for maintenance of the OWS. The OWS is a low maintenance system, but the owner must have the septic tank pumped. We recommend the septic tank be pumped and the effluent filter be cleaned or "hosed off' every two years. There are daily considerations, such as not put- ting plastic or other nonbiodegradable material into the OWS. Water use must be monitored so toilets are not allowed to run when seals malfunction. To illustrate the point, a running toilet can consume in excess of 1000 GPD. A loading of 1000 GPD could flood and irreparably harm the OWS and stress the onsite well. We caution against installation of a water softener. The loading from the backwash of a water softener may be detrimental to OWS. A separate drywell should be constructed for the backwash waste, if a softener is installed. Chemically treated water from a swimming pool or spas should not be introduced to the OWS. LIMITATIONS - An OWS design requires installation by a contractor who is experienced in its installation. Our investigation, layout, design and recommendations are based on data submitted. if subsur- face conditions considerably different from those described in this report are encountered, we should be notified to evaluate the effect on the proposed OWS. If the health department makes modifications to this design, we should be contacted to evaluate the impact on the performance of the OWS. All construction is to be in accordance with the ISDS regulations. Pipe type and size, burial requirements, septic tank construction, and other specifications, which are not depicted in our report, are to conform to the requirements of the ISDS regulations. The installer of the system is to have demonstrated knowledge of the APEHD ISDS regulations and requirements. If there are any questions or if we can be of further service, please call.
