SITE INVESTIGATION A field investigation,performed on January 9,2014,consisted of drilling one(1)profile hole to a depth of eight (8) feet and six (6) percolation holes to an average depth of thirty (30) inches. Percolation tests were performed on January 10,2014. The Location of the Test Holes is shown on Drawing No. 1. A Log of Borings is shown on Figure No. 2. SITE LOCATION AND DESCRIPTION The site is located east of Briggsdale,on the southeast corner of the intersection of Highway 14 and County Road 105, Weld County, Colorado. The site is generally in a plains region and vegetation consists primarily of grasses and cacti. The building site is relatively flat. No rock outcrops were observed at this site. SUBSOILS AND GROUNDWATER CONDITIONS Topsoil-A thin layer of topsoil,approximately six (6) inches,overlies the site. The topsoil should be stockpiled and used as backfill over the absorption field. Clays—Clays with slight to moderate amounts of sand were encountered to the depths explored in the profile hole. The clays appear to be slightly moist, stiff and brown. Groundwater levels were recorded as the borings were advanced, after completion of the drilling operations, and twenty-four (24) hours after the drilling operations. During our field explorations groundwater was not encountered in the profile hole. The groundwater table could be expected to fluctuate throughout the year depending on seasonal moisture variations. 2 PERCOLATION TEST RESULTS A total of six (6) percolation tests were conducted on the site, using the Standard Test Method,as described by the Weld County Health Department. Percolation test holes were presoaked on January 9, 2014, and the test was performed on January 10, 2014. The percolation exploration indicated percolation rates of 48,60,60,60,80,and 80 minutes per inch with an average percolation rate of 65 minutes per inch. Due to the slow percolation rates, an engineered septic system will be required for these conditions. Additional percolation tests conducted on the site may or may not warrant a more desirable site. Additional percolation tests could be conducted for an additional fee. It is our understanding that this facility will operate twenty four hours a day,with a total of nine(9)employees on during each shift. There will be no showers at this facility. For this design we have used 20 GPD per employee, per eight hour shift, for an average daily flow of 180 GPD. In addition to the employees,this design includes sixty(60)truck drivers at five(5)gallons per day for an average daily flow of 300 GPD. Based on the conditions described above, the Weld County I.S.D.S.R. and the water balance spreadsheet, the minimum bed size required is presented in the following table. Septic Tank Size (gal.) 1000 Standard ETA* Bed Area(ft2) 2293 Infiltrator ETA* Bed Area(ft2) 2378 Number of HC** Units 65 *ETA=Evapotranspiration Absorption **HC = High Capacity Quick 4 SEPTIC SYSTEM RECOMMENDATIONS Recommended is a compartmented septic tank of the required size to be followed by an Evapotranspiration absorption field or Infiltrator System of at least the minimum size as mentioned in the table above. The bed should be constructed by a licensed septic system installer,in accordance with the I.S.D.S.R. for Weld County (see Drawing Nos. 2 and 3). An effluent filter could be 3 installed in or after the septic tank and may provide a longer life for the system. The bed should lie a minimum of ten(10)feet from property lines,twenty(20)feet from the proposed residence,and one- hundred (100) feet from any water feature. The contractor and/or owner must carefully plan the elevations of the structures if gravity flow of the wastewater to the septic system is desired. We recommend that the top of the bed or trench be a minimum of one foot below any floor level with gravity sewer otherwise a pump system may be required. This system is to meet all rules and regulations set forth by the Weld County Health Department. The system described in this report may not be the only option available for wastewater treatment and disposal. Other options and technologies may exist which could provide similar levels of treatment and disposal. We recommend that a test pit be excavated prior to construction, and inspected by the Health Department or Engineer to verify the soil conditions at the site. Subsurface conditions described from the borings are based on limited samples and auger cuttings and may vary from visual observations of the test pits which may necessitate changes in the referenced system. The system is to be inspected by a representative of the Weld County Health Department prior to backfilling. CONCLUSIONS All future owners are to be directed to information in Appendix I (General Maintenance Recommendations) of this report. These tests are only valid for the areas tested. Additional percolation tests and soil profile information will be required if the septic system is to be constructed in a different location than covered by this exploration. The findings and recommendations of this report have been obtained in accordance with accepted engineering practices in the field of Geotechnical Engineering. The type of septic system described in this report is only a reference to the I.S.D.S.R.for the county health department and are not to be considered recommendation by the Engineer. There is no other warranty,either expressed or implied. The county health department has final acceptance over these test results and referenced system. All construction shall be in compliance with the septic system permit.

Septic tanks should be pumped a minimum of once every four years. 2. Septic tanks and distribution boxes should be checked at least once a year for sludge accumulation which may clog the leach area if overflow occurs. 3. The leach area should not be used for grazing, sports activities, traffic, or other activity which may compact the soils. 4. Schedule 80 pipe should be used if lines are to be placed under driveways. 5. Trees should not be planted near the leach area so as to prevent roots from clogging the system. 6. If trees are to be planted nearby, they should be located so that the leach area is not shaded. 7. Overuse of strong chemicals, which may kill the bacteria in the system and inhibit decomposition of the sewage,should be avoided. 8. Positive drainage should be maintained over and around the absorption field area to prevent pooling of water. 9. Lines to the tank or leach area should have sufficient ground cover to prevent freezing. REV 07/10/96 Hello
