Correspondence of February 1, 1996 Re: Bialek Dear Betsey: Bob Nelson has asked that I co-sign a letter to you dated February 1, 1996 regarding a Winter season percolation test at 0500 Twining Flats Road in Pitkin County. Rather than co-sign his letter, I wanted to provide a separate letter to clarify a couple of points and reflect the discussions Bob and I have had regarding Winter percolation testing procedures. The first point I would make is that I was not present at the site at any time during the percolation test at 0500 Twining Flats Road. My co-signing of Bob's percolation report, as is generally the case, is to indicate that I have reviewed the written report, discussed its contents or any special conditions with Bob and verified the testing methodology. My signature and seal is to fulfill the requirements of Section 5-5 of the Pitkin County Individual Sewage Disposal System Regulation, as revised in 1995, that the perc test "..be performed by or under the supervision of an RPE or by an Environmental Health Officer of the Department..." Our intent is to indicate that my review of Bob's report work fulfills the "under the supervision of an RPE" requirement. Personally, I have a high regard for Bob's knowledge and experience in the ISDS field in general and have no hesitation in signing off on his work and methodology for percolation testing. Regarding Bob's letter of February 1, 1996, his comments reflect several conversations he and I have had over the years, and in regard to this particular test, with respect to Winter percolation testing. That is, several techniques are available to protect the percolation holes from inclement conditions and that conditions in this area can be highly variable even in the Winter season, often allowing percolation testing. My log notes and photographs from a jobsite in downtown Aspen reflect the fact that frost conditions were minimal and weather conditions sunny and relatively warm on January 9, 1996, the date Bob performed this test procedure. I would support Bob's assertion that conditions for percolation testing were appropriate on January 9, 1996 and that the techniques he used to perform the test and protect the excavation were suitable. Please feel free to contact me if I may provide additional comment. 1001 Grand Ave., Suite 2E • Glenwood Springs, Colorado • (303) 945-1004 February 6, 1996 Ms. Betsey Kipp Page 2 Very Truly Yours, SCHMUESER GORDON MEYER, Jay .

The test hole was excavated at the bottom of a five-foot backhoe pit by hand. At this depth, there was no evidence of frost, and the soil was still quite warm from the mild December temperatures. This testing was performed in a small hole dug by hand to a total depth of seventy one inches at the bottom of the five-foot backhoe pit, The bottom of the backhoe pit was well below frost line at the time of the testing, and immediately after the smaller hole was prepared, the hale was covered with several layers of cellotex insulation and a plastic tarp.

M. and numbered as 0500 Twining Flats Road, Pitkin County, Colorado, Dear Stan, This company has conducted an inspection of the referenced property for the purpose of evaluating the on-site wastewater disposal system serving the existing dwellings constructed in 1981. It was apparent that septic tank effluent was ponded in the seepage bed and it was clogged. As a result of this condition and as requested, Nelson Environmental and Wastewater Solutions, Ltd., performed a soils study and percolation tests for a replacement septic system for the structure. We conducted this study in accordance with Article 5 of the Pitkin County Individual Sewage Disposal System Regulation. We have based our recommendations on the subsurface conditions encountered. We will furnish this letter to the Aspen/Pitkin Environmental Health Department as soon as possible in order for you to obtain a permit to construct this individual sewage system. Existing Construction and Building Site: The building was originally constructed in the late 1960's. The residential property is on a tract of approximately 2 acres. The existing residence is a duplex with a total of eight bedrooms. The top floor unit is a three bedroom residence of approximately 1200 square feet. The lower two floors, including the walk -out basement, make up another unit with five bedrooms, two and one-half bathrooms, and approximately 1800 square feet of finished living area. The site is a lot in the Twining Flats area of Woody Creek. The topography is gently sloping away from Highway 82 at grades of less than 5%. The area of the proposed replacement absorption filed is in the bottom of a cut done years ago, apparently in conjunction with the original construction. Water to the residence is supplied from a well drilled on the East side of the property on the lower level bench about 80 feet lower and 300 feet away from the structure. The well is located a sufficient distance from obvious sources of contamination, such as the existing and proposed septic system location. There is another abandoned well shown on the site plan on the northwesterly corner of the property. This well is no longer useable, and will be properly capped and closed to prevent the possibility of contamination from an adjacent seepage bed, as being proposed. P.O.

The current septic system is a series of two 1250 gallon concrete septic tanks and a 1000 gallon pumping chamber. Septic tank effluent is lifted by a duplex pumping unit to a dosed seepage bed of 1332 square feet, located on the southwesterly portion of the property. The percolation testing in 1981 in conjunction with the construction of the existing seepage bed revealed a rate averaging 8 minutes per inch. Subsurface Conditions: A soil profile, 30 feet West of the structure and within the proposed absorption area was excavated to a depth of nine feet. The excavation revealed that there was no groundwater apparent or bedrock present within nine feet below the surface of the ground. The soils consisted of about 22 inches of dark organic clay loam topsoil. The subsoil was a sandy clay loam with numerous cobbles from two inches to over two feet in diameter. The subsurface soil conditions were evaluated with the standard percolation test procedure at the approximate location shown on Figure 1. With the concurrence of the Aspen/Pitkin Environmental Health Department, only one test hole was used in this location because the shed to be torn down took up much of the proposed absorption area available. The test hole was excavated at the bottom of a five-foot backhoe pit by hand. Before the test, the sidewalls were scrapped and gravel was placed in the test hole to prevent scouring when water was added. Percolation Testing: Percolation testing was performed in the proposed absorption bed area West of the residential building. This testing was performed in a hole excavated to a total depth of seventy one inches. An initial filling of the percolation test holes was done by adding approximately 12 gallons of water to the hole the evening of the day before the percolation test was conducted. The percolation holes were then further pre-soaked by adding water to refill the test holes to a depth of fourteen inches several times for the six: hour period before beginning the percolation test. The results of the percolation testing are presented in Table I. These results indicate the sandy clay loam in this area has an average percolation rate of 16 minutes per inch, a satisfactory percolation rate under Pitkin County criteria and not a lot different from the measurements done fourteen years ago some sixty feet away. 2 Bialek Septic System Investigation and Percolation Tests 0500 Twining Flats Road January 18, 1996 Page 3 Limitations: This report has been prepared according to generally accepted practices in this area for use for sewage disposal design purposes. The conclusions and recommendations submitted in this report are based upon data obtained from our site visits at the location indicated. There is some possibility that the nature and extent of variations in the subsurface soils across the site may not have been evident at the time of this investigation, and may need additional evaluation, if further excavation reveals conditions different from those described. This office should be advised of any unusual situations as soon as possible so that we may reevaluate our recommendations. We hope that this investigation is sufficient for you.
