We conducted this study according to Section VII. of the Colorado Department of Health - Guidelines for Individual Sewaae Systems (1994). We have based our recommendations on the subsurface conditions encountered. Existino Construction. Use. and Site Conditions: The site is a parcel in the Highway 82 corridor approximately six miles South of Glenwood Springs. It is a part of a commercial strip in the area used by construction firms, a lumber yard, a mental health facility and several other businesses. The property served by a well. Currently, the building contains a gas station-convenience store, a liquor store and a 32 -seat dinner restaurant. The ground surface, which appears natural or of older, native fill material in the proposed area of the absorption field, slopes to the West at a 5% grade. There are no irrigation ditches in the area of the proposed absorption system. Subsurface Conditions: A soil profile, within the proposed absorption area, was excavated to as depth of ten feet where an abandoned gas line was encountered. This excavation revealed that no groundwater or bedrock was present. The subsoil consisted of a uniform, gray, cobbly loamy sand. Cobbles are three to thirty inches in diameter, from a depth of 6 inches to the bottom of the profile excavation at 10 feet. Some of the soil may have been moved P.O.

The subsurface soil conditions were evaluated with the standard percolation test procedures at the approximate location shown on Figure 1. The test holes were initially excavated by backhoe, and this company completed the percolation test hole preparation by digging a small twelve -inch diameter hole in the bottom of each excavation with hand tools. Percolation Testing: Percolation testing was performed in the proposed absorption bed area to the South of the existing building and across the concrete driveway. This area is uphill of the drywell or seepage pit for the existing sewage absorption system. This testing was performed in the two holes excavated to a depth of approximately seven feet. Gravel was placed into the bottom of each small percolation test hole to protect the bottom of the hole from scouring when water was added. The percolation holes were pre- soaked before our testing by adding water approximately every hour for eight hours before beginning the percolation test measurements to keep the bottom six inches of the test hole continuously submerged. The results of the percolation testing are presented in Table I. These results indicate the cobbly loam sands have an average percolation rate of 10 minutes per inch, a satisfactory percolation rate under County criteria. Minimum County Requirements: The percolation rates in the loam and clay loam subsoils were measured at an average of 10 minutes per inch. The minimum Garfield County requirements for this installation are based on a system flow of 1200 gallons per day. This flow would break down to the following average daily water use estimates: 1) The convenience store /gas station - 500 gallons per day 2) The liquor store - >200 gallons per day Valley Investment Properties Partnership Hue Mart Building Septic System Site Evaluation and Design Recommendations August 1, 1995 Page 3 3) The restaurant - 500 gallons per day For effective detention time and pretreatment, a total septic tank volume of 2700 gallons, minimum, is required. A standard absorption bed with a minimum of 1140 square feet would also need to be provided. Recommended On -site Wastewater Disposal Design: We recommend that the sewage system consist of an additional two 1250 - gallon concrete septic tanks, a pumping chamber of 1500 gallons, a duplex effluent pump system, a surge tank, and several laterals of leaching chamber units placed in an absorption bed configuration. We have suggested that you plan the construction of the absorption bed to use one of the graveless leaching chamber system designs incorporating all of the manufacturer's installation recommendations. These chambered systems, such as °Infiltrator w or "Biodiffuser nA, provide the required absorption area without the need to haul gravel to the site, and are much easier to place in the subsurface excavation. The use of leaching chambers also permits a 40% reduction in absorption area size under State Guidelines and Policies. An absorption bed of leaching chambers fits better on the available area of the site. The reduction in absorption area size is based on manufacturer's claims and on an approval of such a reduction by the Colorado Department of Health, Water Quality Control Division. We have recommend that the replacement septic system consist of two additional septic tanks located in the area of the existing drywell and a pumping chamber downstream of the tanks. The new septic tanks and pumping chamber would then receive a gravity flow of the wastewater from the building and existing septic tank. The septic tank effluent collected in the pumping chamber would be lifted to a surge tank and gravity flow to the absorption bed as shown in the details. Two effluent pumps sized to provide a flow of 60 gallons per minute against a head of 28 feet are considered necessary. These pumps are the equivalent of the Zoeller Model 161 High Head effluent pump or equal, as specified by the pump supplier and system installer. Because of the space limitations, utility line easements, and the required horizontt separations in the regulations, it is considered necessary to install the dosing chy and pump to a bed located in the best possible area for the soil absorption system ' Distribution to the runs of leaching chamber in the bed is by a surge tank that receives • • Melson Environmental & Wastewater Solutions Ltd E W S TABLE I PERCOLATION TEST RESULT FORM Hole Length Depth at Depth at Drop in Average Hole Depth of Interval Start of Interval End of Interval Water Level Percolation No. (in.)

The absorption bed should be somewhat oversized to accommodate future changes in use. We are recommending a bed using ±1600 square feet of leaching chambers (approxim-.. - •0 units) that provides an effective absorption area and gravel bed equivalent • 2667 -quare feet. We recommend that the water usage of each of the commercial units be metered. Careful record keeping on water usage will allow the system to be evaluated if the occupancy or use of the system changes. The restaurant should be provided with an effective grease trap and maintenance should be done weekly. We also recommend the use of low water use toilets, flushing on 1.6 gallons or less. This will further reduce the wastewater flow to the system (from an estimated 1200 gallons per day to an actual flow approximating 1080 gallons per day). However, although beneficial to the septic system operation, no further reductions in absorption area size are considered for purposes of this report. 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 we may reevaluate our recommendations.

Other lines in the system, from the surge tank to the bed are to be SDR 35 PVC 2) Bed, tanks, and other appurtenances may be field adjusted to best fit the site, provided that minimum setback requirements are met and Garfield County Building and Sanitation Department is notified. 3) Tanks and sewer lines are to be water tight. Use risers as needed to bring septic tank lids to finished grade. 4) The sewage effluent pump is to be a 1/2 Hp Zoeller pump, or equivalent, capable of delivering a flow of 60 gallons per minute against a head of 28 feet. 5) Mercury control floats and a quality alarm system with a mercury float should be used to turn the pump on and off and trigger an audible alarm in the house. 6) The dose volume, set by the spacing of the mercury float switches in the dosing chamber is to be ±300 gallons. 7) The following operations and preventative maintenance schedule is recommended to prolong the life of the system. A) Pump all septic tanks once per year B) Grease traps for the food service establishments should be cleaned weekly C) Check plumbing fixtures on a regular basis and repair all leaks that can add substantial amounts of water to the system. It is also recommended that all toilets be replaced with fixtures flushing with 1.6 gallons of water. P.O. Box 6961 Snowmass Village, CO. 81615 Office (303) 923.3289 Home (303) 923.2766 • D) Meter water usage to all units and keep accurate written accounts of readings and all other maintenance records. 8) It is the contractors responsibility to verify all locations of utilities that may affect the location of facilities as depicted. Verification is to be made with the owner and the affected utility company. Design Calculations: A. Determination of Design Flow 1) The convenience store/gas station - 500 gallons per day 2) The liquor store - >200 gallons per day 3) The restaurant - 500 gallons per day Total Average Daily Flow = 1200 gallons per day Peak Daily Flow (Q) = (1.5)(1200) = 1800 gallons per day B.
