The installation included a 1000 -gallon, two-compartment precast concrete septic tank with an effluent filter, followed by 2 rows of 12 `Quick -4' chambers, for a total of 24 chambers, equaling 237 SF of drain field. Effluent is distributed with a concrete distribution box. The OWS was installed according to specifications. This observation is not a guarantee of workmanship and/or parts and materials. ALL SERVICE septic, LLC should be notified if changes are made to the OWS. LIMITS: The observations were based on information submitted. If conditions are different from conditions described in this letter, ALL SERVICE septic, LLC should be notified. All additional OWS construction must be according to the county regulations. The installer should have documented and demonstrated knowledge of the requirements and regulations of the county in which they are working. Please call with questions.

The property is located outside of Silt Colorado, in an area where OWS are necessary. SITE CONDITIONS The project area is located north of Highway 6 and east of County Road 210. An office building is proposed as indicated on Figure 1. The project area is relatively flat with no vegetation. The proposed office will have approximately 1400 SF. SUBSURFACE The subsurface was investigated by digging one profile pit and three percolation holes, as indicated. The materials encountered in the profile pit consisted of 1 -foot of road base, underlain by sandy clay to 8 feet. Groundwater or bedrock was not encountered. Three percolation holes were dug, in the area of the proposed drain field, as indicated. Percolation rates ranged from 27 to 40 minutes per inch (MPI). A 32 MPI rate will be used to design the OWS. DESIGN SPECIFICATIONS The OWS design is based on a 12 persons office building and an average sewage load of 240 GPD. The installation must include a 1000 -gallon, two-compartment, precast concrete septic tank with an OrencoTM Biotube 4 -inch diameter effluent filter, followed by two gravelless trenches. Each trench must have 12 `Quick -4' chambers for a total of 24 chambers, equaling 237 SF of infiltrative area. Subsurface Investigation and OWS Design Project No. 1421 11/19/07 Page 2 Tank alternatives may be considered. A concrete distribution box with a baffle must be installed to distribute effluent. Construction must be according to the county ISDS regulations, the septic permit provided by Garfield County Environmental Health Department, and this design. OPERATION INFORMATION AND MAINTENANCE The surface of the drain field should be seeded upon completion. Vegetation is an important factor in drain field performance. Erosion control should be practiced prior to and during re -vegetation. Geo - fabrics or plastics should not be used over the drain field. Livestock should not graze on the drain field. Plumbing fixtures should be checked to ensure that no additional water is being discharged to OWS. For Example, a running toilet or leaky faucet can discharge hundreds of gallons of water a day and harm a drain field. The homeowner should pump the septic tank every two years and clean the effluent filter as needed. Garbage disposal use should be minimized, and non -biodegradable materials should not be placed into the OWS. Grease should not be placed in household drains. Loading from a water softener should not be discharged into the OWS. No hazardous wastes should be directed into the OWS. Mechanical room drains should not discharge into the OWS. The OWS is engineered for domestic waste only. ADDITIONAL CONSTRUCTION NOTES If design includes a pump, air release valves and weep holes should be installed to allow pump lines to drain to minimize risk of freezing. Excavation equipment must not drive in excavation of drain field due to the potential to compact soil. Extensions should be placed on all septic tank components to allow access to them from existing grade. Precast concrete tanks and distribution boxes should be used, unless plastic or fiberglass is required. Access to all tank compartments and distribution devices is optimal. INSTALLATION OBSERVATIONS ALL SERVICE septic, LLC, and the county must view the OWS during construction. The OWS observation should be performed before backfill, after placement of chambers and distribution pipes. Septic tanks, distribution devices, pumps, dosing siphons, and other plumbing, as applicable, must also be observed. ALL SERVICE septic, LLC should be notified 48 hours in advance to observe the installation. Subsurface investigation and OWS Design Project No. 1421 11/19/07 Page 3 LIMITS: The design is based on information submitted. If soil conditions encountered are different from conditions described in report, ALL SERVICE septic, LLC should be notified. All OWS construction must be according to the county regulations. Requirements not specified in this report must follow county regulations. The installer should have documented and demonstrated knowledge of the requirements and regulations of the county in which they are working. Please call with questions.
