Dear Mr. Slaven: As requested by Mel Hansen, Hepworth - Pnwlak Geotechnical, Inc., performed percolation testing at the subject site. The services were done in accordance with our agreement for professional services to you, dated April 26, 2007. Hepworth-Pawlak Geotechnical, Inc. previously conducted a subsoil study and percolation test for foundation and septic disposal system designs at the subject site and presented our findings in.a report dated June 23, 2004, Job No. 104206. A profile pit and three percolation test holes had been excavated prior to our arrival on- site at the locations shown on Figure I. The subsoils exposed in the Profile Pit consisted of about b4 foot of topsoil and 2 feet of sandy silty clay with scatted gravel and cobbles overlying sandy silty clay with fragments of sandstone up to boulder size to the crit depth of 31/2 feet. No free water was observed in the pit and the soils were slightly moist. Percolation test holes were hand dug in the bottom of shallow backhoe pits and soaked with water on May I, 2007. Percolation testing was conducted on May 2, 2007, by a representative of Hepworth - Pawlak Geotechnical, Inc. The percolation test results are summarized on Table 1. The percolation tests indicated an infiltration rale between 12 and 17 minutes per inch with an average of 15 minutes per inch. Based on the subsurface conditions encountered and the percolation test results, the tested area should be suitable fora conventional infiltration septic disposal system. We recommend that the Profile Pit be deepened to a depth of 8 feet to verify that bedrock or groundwater doesn't exist below the area of the septic disposal system. If you have any questions or need further assistance, please call our office. Sincerely, HEPWORTH - PAEO Jordy Z.

CHURCH OWC, LLC Onsite Wastewater Consultants November 07, 2007 Gary Slaven 23 South Painted Horse Circle New Castle, Colorado 81647 Subject: OWS Installation Observation Lot 12 Cedar Hills Garfield County, Colorado Job No. C482 Mr. Slaven, This letter presents a summary of the installation observations of the Onsite Wastewater System (OWS) at the subject site. The Installation Observations were performed on November 01 and 06, 2007. The installation was based on the design dated July 12, 2007 under Job No. C482. On November 01, 2007 COWC was called by the general contractor Mel Hanson to observe the installation of the septic tank and the connection to the house. The installation was found to have been generally installed complete with risers as per the July 12, 2007 design. On November 06, 2007 COWC was called by Mel Hanson to observe the installation of the drainfield and the connection to the septic tank. It was observed and noted by the contractor that an additional infiltrator needed to be added to each run as per the design. It was further noted that the distribution box was required to have a baffle in it and the one installed did not have a baffle. The contractor agreed to correct the deficiencies prior to backfilling. The transport line connection between the septic tank and the distribution box was observed to have two clean outs 100 feet apart and an "s" curve installed to diffuse the velocity of the effluent traveling to the distribution box. The components of the OWS appeared to be installed in general conformance with our plans and specifications, with the differences noted. Above noted deficiencies were discussed with the general contractor and will be corrected prior to backfilling and operation of the system. Our installation observations do not imply a guarantee or warranty ofmaterials or workmanship. If there are questions or if we can be of further service, please call.

The design was prepared for Individual Sewage Disposal System (ISDS) permit submittal to the Garfield County Building Department. Subsurface conditions were Investigated by HP Geotech, under their Job No. 107 0286, dated May 8, 2007. SITE CONDITIONS The Investigated site Is a 3 -acre lot. A site plan is Indicated on Figure 1. The site is located In a rural area where OWS Is required. The area of the proposed drain field slopes gently to the north. The site Is vegetated with sparse native grass and moderate cover of sage brush. PROPOSED CONSTRUCTION A four-bedroom single-family residence Is proposed. In accordance with the Garfield County ISDS regulations, the average daily sewage load for a four-bedroom residence is 600 gallons per day (GPD), and with a peak load of 900 GPD. Water will be provided by a public water system. SUBSURFACE CONDITIONS Subsurface conditions were investigated by HP Geotech as presented In APPENDIX A. Subsurface conditions consisted of 0.5 feet of topsoil underlain by 2 feet of sandy clay with scattered gravel and cobbles underlain by sandy silty clay with sandstone fragments to boulder size. No free water was encountered. A Profile Pit is required per the HP Geotech report at the time of construction to confirm no bedrock or groundwater. Three percolation test holes were excavated at the locations presented on Figure 1 to depths of 30 to 36 inches. The percolation test results ranged from 12 to 17 minutes per Inch (MPI). Percolation test results are presented in Appendix A. RECOMMENDATIONS The results of the HP Geotech investigation indicate an OWS can be Installed at the location presented on Figures 1 and 2. The OWS design is based on an average daily sewage load of 9590 West 14th Avenue Ste. 100, Lakewood, CO 80215 Voice 720.898-3434 FAX: 720-898-3455 Feb. 13, 2008 2:39PM Church OWC, LLC No. 0781 P. 3 OWS Design Job No. C482, Page 2 600 GPD and a percolation rate of 15 MPI. A 50% reduction in the drainfleld area was taken for the use of Infiltrator chambers in a trench configuration. A 1,250 -gallon, two-compartment, precast -concrete septic tank Is proposed, COWC suggests a 500 -gallon tank with .dosing siphon be Installed. A dosing siphon collects approximately 100 gallons and then discharges the effluent the drainfield trenches rather than a response to use of water at the home. The dosing siphon is optional, but the installer should price the tank and siphon for consideration by the owner. The drainfield must consist of two Infiltrator chamber trenches, each containing 18 Quick 4 chambers. A 4 -Inch perforated pipe is recommended on the ground to distribute effluent, If additional bedrooms In unfinished areas are possible, it is suggested that the OWS be con- structed to serve the additional loading. The Installation of a properly engineered OWS to serve future build -out can be cost effective, During construction vehicular movement over the absorption trenches should be kept at a minimum to avoid compaction of the receiving soils. Dump trucks and rubber -tire backhoes and excavators are to be kept out of the absorption trenches during construction. The surfaces of the absorption trenches should be seeded after Installation of the OWS. A seed mix adapted to local conditions without Irrigation should be sown. These mixes do not require Irrigation and may develop a growth 10 to 15 Inches high. No automatic sprinkler system should be installed over the absorption area. INSTALLATION OBSERVATIONS The installation of the OWS is to be observed by the design engineer. Observations are prior to final backfill. The final observation should be performed prior to backfill, after placement of the gravel and distribution pipes, Septic tank, dosing siphon, flow splitter basin, sewer and effluent piping, as applicable, can be observed during the visit. Our office should be called to observe the Installation of the OWS 24 hours In advance, Instal- lation observations, OWS redesigns, staking of drainfield or additional site visit requirements In addition to those required for this design, are not Included with this design and will be at an additional fee per the service agreement and/or fee schedule. OPERATION ANO MAINTENANCE The owner must realize an OWS is different from public sewer service. The owner must also be aware of, and assume responsibility for, ongoing maintenance of the system. In the absence of a monitoring program, the septic tank should be pumped every two years or more frequently If needed. Effluent filters and screened vaults, as applicable, are to be cleaned at the time of pumping or as needed. There are daily considerations such as not putting plastic or other non - biodegradable materials into the septic system. Garbage disposal use should be minimized to reduce the frequency of pumping. Water use must be monitored so toilets are not allowed to run when seals malfunction. To Illustrate the point, a running toilet can use In excess of 1000 GPD, which may flood and Irreparably harm the system, Feb. 13. 2008 2:39PM Church OWC, LLC No, 0781 P. 4 OWS Design Job No. C482, Page 3 COWC cautions against the Installation of a water softener. The hydraulic loading from the backwash of a water softener Is detrimental to an OWS and a separate drywell should be constructed for the backwash waste, if a softener Is Installed. No landscaping or plastic can be used over the field, which will reduce performance of the field. Chemically treated water from a swimming pool or spas should not be Introduced to the OWS. The design of the OWS Is based on the treatment of domestic sewage only. No Industrial or hazardous wastes should be Introduced into the OWS. poor drains should not discharge Into the OWS. LIMITATIONS Our investigation, layout, design, and recommendations are based on data submitted. If conditions different from those described are encountered, we should be called to observe the conditions. If proposed construction is changed, we should be notified to evaluate the effect of the changes on the wastewater system. All construction Is to be in accordance with the ISDS regulations. Pipe type and size, burial requirements, septic tank construction, and other specifi- cations, which are not depicted In our report, are to conform to ISDS regulations. The Installer of the system is to be licensed with the county health department, and is to have demonstrated knowledge of the ISDS regulations and requirements. If then: are questions, please call.

Dear Mr. Slaven: As requested by Mel Hansen, Hepworth - Pawlak Geotechnical, Inc., performed percolation testing at the subject site. 'The services were done in accordance with our agreement for professional services to you, dated April 26, 2007. Hepworth-Pawlak Geotechnical, Inc. previously conducted a subsoil study and percolation test for foundation and septic disposal system designs at the subject site and presented our findings in a report dated June 23, 2004, Job No. 104 206. A profile pit and three percolation test holes had been excavated prior to our arrival on- site at the locations shown on Figure 1. The subsoils exposed in the Profile Pit consisted of about i/ foot of topsoil and 2 feet of sandysilty clay with scatted gravel and cobbles overlying sandy silty clay with fragments ofsandstoneup to boulder size to the pit depth of 31/2 feet. No free water was observed in the pit and the soils were slightly moist. Percolation test holes were hand dug in the bottom of shallow backhoe pits and soaked with water on May 1, 2007. Percolation testing was conducted on May 2, 2007, by a representative of Hepworth - Pawlak Geotechnical, Inc. The percolation test results are summarized on Table 1, The percolation tests indicated an infiltration rate between 12 and 17 minutes per inch with an average of 15 minutes per inch. Based on the subsurface conditions encountered and the percolation test results, the tested area should be suitable for a conventional infiltration septic disposal system. We recommend that the Profile Pit be deepened to a depth of 8 feet to verify that bedrock or groundwater doesn't exist below the area of the septic disposal system. If you have any questions or need further assistance, please call our office. Sincerely, HEPWORTH - P i� Jordy Z.
