We understand that MTI-GEO will also be responding to some of the comments in a separate letter from their office. MOUND DESIGN COMMENTS 1) The basal area calculation was not shown on the plan because (in this case) it was not critical.. The basal area that would develop due to construction on the hillside would be far in excess of that recommended by the EPA Design Manual for Onsite Wastewater Treatment and Disposal Systems, Table 7-10, which allows a loading rate of 1.2 gpd/sf for soils with perc rates up to 30 mpi. However, we have now shown a minimum basal area calculation based on a loading rate of 0.6 gallons per day per square foot. This would be in the upper middle of the rates recommended in the Converse and Tyler publication. The latest information from MTI-GEO shows fast perc rates in the upper 18" of soils, so our initial design rates have been verified. 2) We concur that since the elevations are such that the system needs a pump, it would make sense to have a pressure distribution system in the mound. We have enclosed a standard detail for the piping for the pressure distribution layout. 3) We will modify the sand specification to conform with the recommended specification. 4) We have enclosed a sheet of general construction specifications for mound construction. 923 Cooper Avenue • Glenwood Springs, CO 81601 Telephone: (970) 945-8676 • FAX: (970) 945-2555 Aspen/Pitkin Environmental Health June 14, 1996 (Revised June 18, 1996) Page 2 5) A note will be added to the plans which specifies stages of construction which will require inspection. These stages will be: preparation of basal area, placement of intermediate fill, placement of sand fill, placement of rock and distribution piping, and final cover and grading. 6) The dose for the tank specified will be 580 gallons, and the emergency storage available would be approximately the same. 7) The calculated total dynamic head for the pump 28 feet, we specified 30 feet. A Hydromatic SPD100H submersible effluent pump would be a good choice, and we have included a pump curve for that pump. If you have any questions, or need additional information, please contact us. Sincerely, HIGH COUNTRY ENGINEERING, INC. Ti 6th Y _P. eck, P.E. P 'ncipal Engineer T B/soe cc: Stan Helenschmidt, MTI-GEO John Muir, Robert Trown Associates C MOUND SYSTEM SPECIFICATIONS 1. The mound shall be placed parallel to the contours. 2. Grass, shrubs and trees shall be cut close to the ground surface and removed from the site. 3. The mound site shall be tilled to a depth of 8 inches to roughen the surface and incorporate the vegetation. This can be done with a plow or chisel teeth mounted on a tool bar attached to the bucket of a backhoe. Standard backhoe bucket teeth are not satisfactory and shall not be used. 4. A layer of sand should be placed before it rains on the tilled area. Placement of the sand should be such as not to rut or compact the tilled area. All work should be performed from the upslope side so as not to compact the downslope area. 5. Place the proper depth of sand, then form the sand/gravel interface area with the area bottom being level. Protect this infiltrative area from rain by placing the aggregate prior to rain. 6. Place the screened rock (aggregate) to the specified depth and area. 7. Place the pressure distribution pipe, connect it to the force main and cover with aggregate. 8. Cover the aggregate with a geotextile filter fabric. 9. Place a minimum of 12 inches of suitable soil cover on the sides of the mound and to the necessary depth for grading on the top of the mound. 10. Final grade the mound and surrounding area with light weight equipment so surface water moves away from the mound and does not accumulate on the upslope side of the mound. 11. Seed and mulch the entire exposed area to avoid erosion. Landscape with shrubs and plants as desired.

Attn: Nancy MacKenzie 130 South Galena Aspen, CO 81611 Re: Davidson Residence/Stony Creek Ranch ISDS HCE File Number 96004.15 Dear Ms. MacKenzie: This letter is in response to my conversation this morning with your consultant, Warren Brown. We discussed the ISDS for the Davidson Residence, and agreed to increase the spacing of the distribution pipes and the perforations in the distribution pipes in order to maintain a reasonable pump size and allow us to stay with the pump specified. Thus, the contractor will be informed of the change in writing, but the drawing will not be changed until the system is complete and the changes can be incorporated into the record drawing. The changes we discussed were, specifically, the distribution piping will be changed back to a spacing of six feet on center, and the perforation spacing will be changed to 48" on center instead of 30" on center. If you have any questions, or reed additional information, please contact us. Sincerely, HIGH COUNTRY ENGINEERING, INC. Ti othy P. Beck, P.E.

Director June 13, 1996 Recycled Paper �9 Tri -County Health Department Serving Adams, Arapahoe and Douglas Counties 'JUN 1996 Nancy MacKenzie Aspen -Pitkin Environmental Health Department 130 S. Galena Street Aspen, Colorado 81611 Dear Nancy: I have completed the review of the proposed Individual Sewage Disposal System for the Davidson Residence Addition, at 2761 Owl Creek Road. I offer the following comments. SOILS AND PERCOLATION TEST RESULTS The percolation test results indicate that the upper topsoil is permeable (perc rates of 11-14 minutes per inch), to a depth of 16 inches, however, the soil log indicates that the topsoil is a soft gray clay, which raises a concern whether it is actually permeable. In order for mounds to function, topsoils must have acceptable percolation rates (no more than 60 mpi), proper texture, (e.g. sandy clay), or have some structure which will allow water to infiltrate into the upper soil horizon. The log indicates "slightly block", which may mean a blocky structure, which would allow water to infiltrate, or it may indicate shrinkage cracks in the clay, which would seal off and not allow water to percolate. I believe that the topsoil requires additional evaluation, to determine if a mound is acceptable, and recommend the following: 1) I see no indication that the percolation test holes were pre-soaked for 24 hours before the test. The pre-soak is critical to evaluating clay soils. I would ask the engineer if the holes were presoaked, and if not, the tests in the holes 1 and 5 should be repeated after a minimum of 24 hours presoak. 2) I would also recommend a minimum of 3 additional percolation tests in the shallow topsoil area (basal area) which will be covered by the mound. 3) The additional percolation test holes should also be logged and classified, to determine if the soil texture and/or structure is acceptable and to determine if the depth of -the topsoil is of adequate depth under the proposed mound (12"-18") minimum. Administrative Office ❑ 7000 East Belleview Avenue ❑ Suite 301 ❑ Englewood, Colorado 80111-1628 303/220-9200 ❑ FAX 303/220-9208 9 June 13, 1996 Page 2 If, after following the above recommendations, the topsoil is found to be of acceptable texture (sandy clay with structure), is acceptably permeable, and of sufficient depth under the mound fill ( say 12"-18") , the mound concept is acceptable. If the topsoil is not permeable (i.e. peres more than 60 mpi) , if the soil is of clay texture, or not of sufficient depth, a mound is not recommended and an alternative system should be considered, such as an evapotranspiration system. MOUND DESIGN If the additional evaluation proposed above indicates that a mound is acceptable, the proposed mound design needs to be revised, in order to meet the requirements of your regulation and to assure it will perform adequately. The revisions are listed below. 1) The design does not include a calculation of basal loading rate (basal area of mound divided by total design flow) . This needs to be included to evaluate the design. The Wisconsin Mound Soil Absorption System Siting, Design and Construction Manual, by Converse and Tyler, recommends basal loading rates, based on surface soil texture. In this case, a basal loading rate of 0.2 gallons/ sq. ft. /day may be appropriate, considering the impermeable clay soils below the topsoil. 2) The distribution system must be designed for uniform effluent application throughout the mound. The proposed system will not provide uniform distribution. Uniform distribution systems typically utilize relatively small diameter laterals (1"-2") with smaller holes spaced further apart (e.g. 1/4" holes @ 3' spacing). The method for designing a uniform distribution system is prescribed in the Wisconsin Mound manual. I have also included a section of our Regulation I-96 pertaining to uniform distribution, for reference. 3) It is advisable to use a sand within the mound which meets a "filter sand" specification. In section 12-5.1 in your regulation, filter sand must have an effective size of 0.6 mm and a uniformity coefficient of 4.0 or less. The sand specified has an effective size of 0.13 mm, and a uniformity coefficient of less than 5. This sand may be too fine, which may result in excessive clogging. 4) The mound design must include construction specifications, as described in the Wisconsin manual. If not properly constructed, a mound may not perform. For example, improper construction could result in compaction of the topsoil under the mound, resulting in failure. 5) The plans do not specify inspections. Several inspections by the engineer are critical to verify that the mound is properly constructed. Examples would be: inspection of basal area C June 13, 1996 Page 3 K J preparation, placement of fill (fill below sand filter, sand filter, rock, final cover, etc) . The engineer needs to specify and perform the necessary inspections, and provide certification that the necessary inspections have been performed. Please do not hesitate to call if you have any questions. Sincerely, wloe'-zo.cr.�/ Warren S. Brown, P.E.

Z Subject: Report of Percolation Testing, Davidson Residence Addition, 2761 Owl Creek Road, Aspen, Colorado i Job No. G96 134 Dear Mr. McGarry: MTI GEO has performed percolation testing for a new leach field at the subject site. The testing was performed based on your verbal authorization and in accordance with Pitkin County Regulations. Seven percolation holes and one profile pit were excavated at the site. The subsoils exposed in the profile pit, beneatha proximately 1.5 feet of topsoil, consisted of clays to a depth of 9.5 feet. The clay has minor mounts of gravel between 1.5 and 6.0 feet in depth. Three of the percolation pits were hand excavated 14 inches deep in the bottom of 3 foot deep backhoe excavated pits. Two were hand excavated to approximately 28 inches and two were hand excavated to approximately 15 inches_ The approximate pit locations are shown on Figure 1. The trench log of the profile pit is attached as Figure 2. Percolation pit number Pere 7 showed average percolation rates of 38 to 50 min/inch. However, all of the other deeper pis showed rates outside of the range considered acceptable for a standard infiltration type sewage disposal system. The two shallow pits (Pere 1 and Pere 5) showed rates ranging from 6 to 19 minutes/inch. The attached Table I shows specific percolation rates as measured in the field. The average percolation values which are shown in bold are in the "below 6 inch" zone of the hole'' -where design rates are measured. The percolation of the upper soils will be relied upon for design of a "mound" system currently being designed by High Country Engineering. 5080 Road 134 • Glenwood Springs - Colorado • 81601 rr■■rr� JUN -06-1996 13:43 HIGH COUNTRY ENGINEERING Norris & Associates May 30, 1996 Page 2 If you have any questi jus, or if we may be of further service, please call.

We understand that MTI-GEO will also be responding to some of the comments in a separate letter from their office. MOUND DESIGN COMMENTS 1) The basal area calculation was not shown on the plan because (in this case) it was not critical. The basal area that would develop due to construction on the hillside would be far in excess of that recommended by the EPA Design Manual for Onsite Wastewater Treatment and Disposal Systems, Table 7-10, which allows a loading rate of 1.2 gpd/sf for soils with perc rates up to 30 mpi. However, we have now shown a minimum basal area calculation based on a loading rate of 0.6 gallons per day per square foot. This would be in the upper middle of the rates recommended in the Converse and Tyler publication. The latest information from MTI-GEO shows fast perc rates in the upper 18" of soils, so 2) We concur that since the elevations are such that the system needs a pump, it would make sense to have a pressure distribution system in the mound. We have enclosed a standard detail for the piping for the pressure distribution layout. 3) We will modify the sand specification to conform with the recommended specification. 4) We have enclosed a sheet of general construction specifications for mound construction. 923 Cooper Avenue • Glenwood Springs, CO 81601 Telephone: (970) 945-8676 • FAX: (970) 945-2555 I . Y 1� Q Aspen/Pitkin Environmental Health June 14, 1996 Page 2 5) A note will be added to the plans which specifies stages of construction which will require inspection. These stages will be: preparation of basal area, placement of intermediate fill, placement of sand fill, placement of rock and distribution piping, and final cover and grading. 6) The dose for the tank specified will be 580 gallons, and the emergency storage available would be approximately the same. 7) The calculated total dynamic head for the pump 28 feet, we specified 30 feet. If you have any questions, or need additional information, please contact us. Sincerely, HIGH COUNTRY ENGINEERING, INC. Tim heck, Prin ipal Engineer TP /so cc: Stan Helenschmidt, MTI-GEO John Muir, Robert Trown Associates MOUND SYSTEM SPECIFICATIONS 1. The mound shall be placed parallel to the contours. 2. Grass, shrubs and trees shall be cut close to the ground surface and removed from the site. 3. The mound site shall be tilled to a depth of 8 inches to roughen the surface and incorporate the vegetation. This can be done with a plow or chisel teeth mounted on a tool bar attached to the bucket of a backhoe. Standard backhoe bucket teeth are not satisfactory and shall not be used. 4. A layer of sand should be placed before it rains on the tilled area. Placement of the sand should be such as not to rut or compact the tilled area. All work should be performed from the upslope side so as not to compact the downslope area. 5. Place the proper depth of sand, then form the sand/gravel interface area with the area bottom being level. Protect this infiltrative area from rain by placing the aggregate prior to rain. 6. Place the screened rock (aggregate) to the specified depth and area. 7. Place the pressure distribution pipe, connect it to the force main and cover with aggregate. 8. Cover the aggregate with a geotextile filter fabric. 9. Place a minimum of 12 inches of suitable soil cover on the sides of the mound and to the necessary depth for grading on the top of the mound. 10. Final grade the mound and surrounding area with light weight equipment so surface water moves away from the mound and does not accumulate on the upslope side of the mound. 11. Seed and mulch the entire exposed area to avoid erosion. Landscape with shrubs and plants as desired. t Pump Characteristics Pum /Motor Unit Submersible Manual Model (50) MH1 MH2 MH6 MH4 I MH5 Automatic Models AHI— Shaft Stainless Steel Mechanical Shaft Seal Seal Faces: Carbon/Ceramic Seal Body: Brass Spring: Stainless Steel Bellows: Buna-N Horse ower 1/2 Full load Ams 15.0 7.5 Lower Bearing Motor Type_ Capacitor Start Three -Phase R.P.M. 3450 Phase 0 1 3 Voltage 115 230 200 460 1 575 Manual Model (100) MH2 MH6 MH3 MH4 MH5 Automatic Models AH2 — — — Horse ower 1 Full Load Ams 9.5 1 4.5 4.0 1 1.7 1.5 Motor Type (ap.

Davidson has received a conveyance of Jefferies' interest in the Easement and the real property benefited thereunder. B. The parties have discovered that an erroneous legal description was contained in the Easement which granted rights to a pipeline for the delivery of water from a spring located on the "LPG Property" to the ''Jefferies Property", as those terms are defined in the Easement. The Jefferies Property is now owned by Davidson. C. The parties are entering into this Amendment for purposes of correcting the legai description and amending the Easement as set forth hereafter. NOW, T HEREFORE, in consideration of the undertakings herein contained, which constitute a good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree: I .

P. 0. Box 5759 Snowmass Village, CO 81615 Subject: Response to Review Comments From Tri County Health Department Dated June 13, 1996 and Supplemental Percolation Testing, Davidson Residence Addition, 2761 Owl Creek Road, Snowmass Village, Colorado Job No. G96 134 Gentlemen: The following provides response to Items 1 through 3 of the Tri County Health Department review comments for the proposed Individual Sewage Disposal System for the subject residential addition dated June 13, 1996. Other comments will be addressed by Mr. Tim Beck of High Country Engineering. Also submitted herewith are the results of six additional percolation tests performed in the proposed mound system area and logs of percolation test holes for the recent six percolation tests. Response to Review Comments Item 1 Percolation tests reported in our May 30, 1996 letter were indeed pre-soaked prior to testing for a period of eight hours and tested the following day (within 24 hours of the presoak period). This method is in accordance with the procedure described in the Pitkin County Testing Procedures Article 5-3 (copy attached). Considering the percolation rates of the soils, presoaking of the soils continuously for 24 hours would be impractical and would in our opinion not significantly affect the percolation rates of the soil. Item 2 Six additional percolation tests were performed in and adjacent to the proposed mound area. These percolation holes were presoaked for eight hours and tested the following day. It rained the evening prior to percolation testing and during the day that the holes were tested. The ground in the area of the tests was very wet. Percolation rates for the recent six tests ranged from 3 to 12 minutes per inch. Item 3 Logs of the recent percolation test holes are attached. Based on our observations and testing, soils with suitable percolation characteristics extend to at least 12 to 18 inches below existing ground surface. 5080 Road 154 • Glenwood Springs • Colorado • 81601 Article 5: Sail Tests 5-1 Location: At least 3 soil perc tests are required in the area where the absorption system is to be located. They must be spaced uniformly over the proposed area, but there must be at least one (1) test hole in every soil texture type in the area and in every twelve hundred (1200) square foot area of the absorption system. 5-2 Dimensions: The perc test holes should be six (6) inches in diameter, and no less than four (4) inches and no greater than twelve (12) inches in diameter where prohibitive soil or geological conditions exist. The holes must end at the depth of the proposed absorption system. The perc tests must be done in the soils that comprise the 4 feet of acceptable soils beneath the bottom of the absorption field. 5-3 Procedure: Perc test holes must be filled with water to a depth of 14 inches or more for at least 8 hours, but not more than 24 hours, before doing the perc test. They must be refilled with water if necessary to a depth of at least 14 inches prior to final measurement. The time for the water to drop one inch within the lower six (6) inches of the perc test hole is measured. The applicant must report the perc rate in minutes per inch drop. 5-4 Calculations: The perc rate is the average rate of the perc tests after the rate has stabilized in all the test holes in the proposed absorption area. 5-5 Performance of Percolation ("Perc") Tests: The perc test must be performed by or under the supervision of an RPE or by an Environmental Health Officer of the Department unless adequate tests previously performed by an RPE are submitted with the application for a permit. The Environmental Health Officer may request additional perc tests if the results are conflicting or questionable. If the applicant demonstrates to the satisfaction of the Department that the system is not dependent upon soil absorption, the requirement for perc tests may be waived. 5-6 Alternate Perc Test: Other soil test procedures such as soil analysis may be approved by the Environmental Health Officer if the test results of alternate procedures meet or exceed those determined using the test procedure detailed in this article. 5-7 Soil Profile: One soil profile hole must be drilled or dug to provide observation of the soil profile in the area of the soil absorption system. The hole must be prepared at least eight (8) feet deep. The hole must be prepared so as to provide identification of the soil profile four (4) feet below the bottom of the soil absorption system. (The hole may be terminated when groundwater or bedrock is encountered.) 16 1 0 mWEO TGEOTECHNICAL ENGINEERING I ENVIRONMENTAL SERVICES CONSTRUCTION MATERIALS TESTING AND INSPECTION June 17, 1996 Mr. Patrick McGarry Norris and Associates, Inc.
