Box 179 500 Broadway Eagle, Colorado 81631-0179 RE: Issuance of Individual Sewage Disposal System Permit No. 1812-98. Tax Parcel # 2101-213-00-008. Property Location: Vail Ski area, bottom of Chair Lift # 21. Enclosed is your ISDS Permit No. 1812-98. It is valid for 120 days. The enclosed copy of the permit must be posted at the installation site. Any changes in plans or specifications invalidates the permit unless otherwise approved. Systems designed by a Registered Professional Engineer must be certified by the Engineer indicating that the system was installed as specified. Eagle County does not perform final inspections on engineer designed systems. Your TCO will not be issued until our office receives this certification. Permit specifications are minimum requirements only, and should be brought to the property owner's attention. This permit does not indicate conformance with other Eagle County requirements. If you have any questions, please feel free to contact the Environmental Health Division at 328- 8755. cc: files LKP Engineering, Luiza Petrovska LKP Engineering, Inc.

Box 179 Eagle, CO 81631 RE: ISDS Application, Chair 21, Vail Ski Resort Eagle County, Colorado Project No. 98124 Dear Ray: We are submitting the application for the septic system at Chair 21, on the Vail Mountain Ski Resort, Eagle County, Colorado. The system will service public restrooms. Mountain Services of Vail Associates is proposing to construct restrooms near the bottom of Chair 21. The effluent from the restrooms will be treated by the Devap 2000 system. The system is odorless and waterless process. It reduces the human waste and evaporates the liquid waste. The remaining solids are emptied at the end of the ski season when the access roads are passable. This system has been used successfully in the White River National Forest and Jackson Hole for number of years. Also, this system has been in service, for two yers, on the Vail Mountain at Chair 2. All of the above systems have similar high uses by skiers, and are located on high elevation areas. In addition, the proposed system for Chair 21, will have a 2000 gallon septic tank for a possible high use overflow of liquids not evaporated by the system either due to malfunction of the system or surge in use. Also, part of the constructed system will be a 1000 gallon tank for the waste water from hand washing. The water for hand washing will be hauled to the restrooms on daily basis. At 5 oz. per hand washing, the 1000- gallon tank will provide storage for water from 178 hand washes per day for 150 days. This tank will also be pumped out at the end of the ski season.

The existing septic system was designed for less than 100 or so flushes per day. Peak days have started to reach the capacity of the existing system. The Devap System is a waste conversion and reduction system that is an odorless, waterless process that uses no chemicals to reduce human waste. Liquid waste is evaporated. Sinks for hand washing are proposed which will bypass the Devap System and be directed into a standard septic system. Each Devap System can handle up to 150 uses per day, so the 2 systems can handle up to 300 flushes per day. On peak days where use exceeds 300 flushes, overflow from the system is proposed to go to a septic tank (same tank as used for hand washing) and then to an absorption field. DESIGN FLOW A. Restrooms The Devap System does not use water to flush toilets. The restrooms are to be open to the public (using the ski area). I have contacted Alex Raycheck who sells the Devap System (1-800- 524-1097) to inquire on sizing and system capacity. Based on his experience with systems installed in areas of similar elevations and uses, and systems installed in the Vail Ski Area, the following assumptions have been made in the design: Peak Number of Uses Expected: 500 uses Capacity of 2 Devap Systems: 200 uses Excess Above Capacity: 300 uses 200 uses per day = 12 gallons of effluent. To be conservative assume 30 gpd. B. Hand Washing The hand washing sinks are to be push-button, low -flow type. They are 5 ounce valve sinks that provide for approximately 1000 hand washes per day. The water for the hand washing sinks is to be supplied from a 74-gallon tank to be filled daily (or piped from a tank at PHQ) 500 uses per day @ 5 ounces per use = 2500 ounces — 20 gallons To be conservative use 75 gallons Average Daily Flow Qavg = 30 gpd from overflow + 75 gpd from hand washing Qavg = 105 gpd Qmax = 105 gpd x 150% Qmax = 158 gpd LKP Engineering, Inc. 3 SOIL PROFILE AND PERCOLATION TEST One, 8 feet deep soil profile hole and three percolation holes were excavated within the proposed leachfield area as shown on the location sketch. The soil profile consisted of one foot of topsoil over 7 feet of brown, slightly clayey, sandy gravel with cobbles and boulders. The percolation holes were dug and presoaked on September 7, and we ran the tests on September 8, 1998. The average percolation rate recommended for design is 20 minutes per inch. ABSORPTION AREA A = Qmax/5✓20 = 158gpd/5✓20 = 141 square feet Compare with. -Long Term Acceptance Rate of 0.72 gpd/sf A=158/0.72L219,square feet - more conservative 50% reduction for Infiltrators in a trench configuration A=11�Osquare feet Alloed area of one Infiltrator for design = 15.5 square feet Use infiltrators in two trenches with four infiltrators each. be connected with serial distribution.
