Colorado 80303 Subject: OWS Observation, Proposed Residence Lot 14, Crystal River Park Pitkin County, Colorado Job No. 10363 Dear Mr. and Mrs. Downey, As requested, we observed the installation of the onsite wastewater system (OWS) at the subject site on July 8, 1999. The OWS was designed under our Job No. 10363 dated December 23, 1998. The installation included one 1000 -gallon two-compartment tank with an effluent filter on the outlet and a 36 feet x 6 feet x 10 feet drywell with 3 vertical perforated PVC pipes. The area of drywell is greater than the required area of 1032 square feet (SF). The observed components of the OWS were installed in conformance with the plans and specifications. An as -built drawing is attached as Figure 1. If you have any questions concerning this project, or if we can be of further service, please call. Very truly yours, CHURCH & Edward O.

ENGINEERS & GEOLOGISTS December 23, 1998 Chuck and Doris Downey 5325 Kewanee Drive Boulder, Colorado 80303 Subject: OWS Design, Proposed Residence Lot 14, Crystal River Park Pitkin County, Colorado Job No, 10363 Dear Mr. Downey, As requested, we prepared an Onsite Wastewater System (OWS) design for the proposed residence. Nelson Environmental and Wastewater Solutions (NEWS) investigated subsurface conditions. Results of the NEWS investigation are presented in Appendix A. SITE CONDITIONS -The site is a 1.8 -acre lot in a rural mountainous residential area, where an OWS is required. The proposed drain field area has an approximate 10% slope to the southwest. There is a moderate cover of grasses and aspens at the proposed drain field area. A stream is located east of the proposed drain field. The home will be served water by a community water district. PROPOSED CONSTRUCTION - The proposed residence will have three bedrooms and less than 2000 square feet (SF) of living area. Aspen/Pitkin Environmental Health Department (APEHD) confirmed the number of bedrooms of the residence. The location of the proposed residence is presented on Figure 1. The sewage load for a three-bedroom residence with less than 2000 SF of living area is 450 gallons per day (GPD) using the APEHD sewage loading calculation. Sewage loading with a 1.75 peaking factor is 788 GPD. This loading includes a garbage grinder, dish washer, and washing machine. SUBSURFACE CONDITIONS - Subsurface conditions were investigated by NEWS. We were not given profile hole information by NEWS. We discussed subsurface conditions with NEWS. NEWS stated subsurface conditions consisted of a thin topsoil layer; underlain by soil to the maximum depth explored of 10.25 feet. Other sources state the test pit was actually 16 feet deep. As requested, this design is based on a profile pit 16 feet deep. A profile pit 16 feet deep should be excavated prior to construction of the drain field to confirm subsurface conditions and our proposed OWS. We understand APEHD has approved this condition for the issuance of a permit. No ground water or bedrock was reported in the profile hole. Percolation test results indicate percolation rates ranged from 32 minutes per inch (MPI) to 57 MPI. The average percolation. rate is 43 MPI. RECOMMENDATIONS - We prepared a septic tank and a drywell OWS design for the site. A "standard" shallow gravel drain field could not be installed at the site due to site constraints such as the water line and lot size. The OWS design is based on a peak sewage load of 788 GPD and a percolation rate of 43 MPI. We recommend the installation of one 1000 -gallon two-compartment pre -cast concrete septic DENVER 4501 Wadsworth Boulevard Wheat Ridge, CO 80033 CASTLE ROCK 303.660.4358 303.463.9317 Fax: 303.463.9321 EVERGREEN 303.816.1455 tank with an effluent filter on the outlet. We recommend a 6 feet wide by 36 feet long by 10 feet deep dry well be installed. The OWS should be constructed similar to Figures 1 through 3. The proposed OVA'S was designed for a three-bedroom residence less than 2000 SF of living area. If additional bedrooms are anticipated, we believe the installation of a larger OWS at the time of initial con- struction to accommodate any "build -out" of the residence is cost effective. The septic tank would have to be increased by 328 gallons of capacity for each additional bedroom. Each additional bedroom will require a minimum of 344 SF of dry well. OPERATION AND MAINTENANCE - The owner must realize an OWS is different from a public sewer system. The owner must be aware of and assume responsibility for maintenance of the system. We recommend the septic tank be pumped and the effluent filter be cleaned (hosed off) at every two years. There are daily considerations such as not putting plastic or other non -biodegradable materials down the septic system. Water use must be monitored so toilets are not allowed to run when seals malfunction. To illustrate the point, it should be noted a running toilet would consume in excess of 1000 GPD if allowed to run. An excess 1000 -gallon loading will flood and irreparably harm the system. LIMITATIONS - Our layout, design and recommendations are based on data submitted. If subsurface conditions different from those described in this report are encountered, we should be called to observe the subsurface conditions. If proposed construction changes, we should be notified to evaluate the effect of the changes on the proposed system. All construction must be in accordance with county 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 must have knowledge of the ISDS regulations and requirements. The OWS design includes one installation observation. Additional observations are not included in the cost of this design. If there are any questions or if we can be of further service, please call. CHURCH & Associates, AEQ�S Edward O.

Downey 5325 Kewanee Drive • Boulder, Colorado 80303 • (303) 499-5272 Ms. Jannette Whitcomb Aspen/Pitkin Environmental Health Dept. 130 So. Galena St. Aspen, CO 81611 Dear Jannette: January 2, 1999 i 07 This Metter confirms the outcome of the meeting we had on December 18, 1999 Our discussion focused on the percolation pit depth excavated this past September on Lot 14 in the Crystal River Park Subdivision in Redstone. The actual perc measurements taken by Bob Nelson are not in question, but there is confusion around verification of the soil consistency and the absence of ground water and bedrock below the lowest perc depth of 124 inches (10 1/3 feet). In a follow-up telephone conversation with Duane Piffer after our meeting, he said that he did indeed excavate the perc pit to a depth of 16 feet and that the soil was consistent to that depth with no ground water or bedrock present. However, Bob Nelson has since developed serious health problems and is unlikely to be able to verify Duane's statement. Unfortunately, Bob Nelson's soil evaluation and percolation test report dated November 5, 1998 failed to mention soil conditions below 124 inches. Without soil verification below 124 inches, the surface area required for the drain field is excessive and will result in the destruction of mature spruce, pine and aspen trees and considerable disruption to the site, its native grasses and vegetation. To prevent this, you recommended a strategy that would allow the septic engineering be done on the assumption that the soil is consistent to a depth of 16 feet, and that on-site verification be performed as the first step in the actual construction process. If a problem with soil consistency is uncovered, changes to the septic design will have to be made to accommodate the finding. Church and Associates is satisfied with this approach and has designed the system based on this assumption.

Per our conversation, I would like you to look at the following examples of ISDS design calculations. Please note that living space, bedroom & potential bedroom (workshop) count, and perc rate determine the size of the aborption area. The absorption area would be the same size for a standard pipe and gravel bed system and a drywell. If you have any questions please call. These are only examples. This department does not have actual perc rates for the Downey site. All examples assume a house size of less than 2000 sq.ft. (75 gpd). • 3 bedrooms + 1 workshop; perc rate 30 mpi; absorption area 1150 sq.ft. • 3 bedroom; perc rate 30 mpi; absorption area 863 sq.ft. • 3 bedroom + 1 workshop; perc rate 15 mpi; absorption area 813 sq.ft. • 3 bedroom; perc rate 15 mpi; absorption area 610 sq.ft.
