It is our understanding that this system will service a commercial facility, with no future expansion planned at this time. The wastewater strength is anticipated to be similar to a single family residence because the system will only service a half bath. SITE INVESTIGATION A field investigation, performed on October 14, 2014, consisted of drilling one (1) profile hole to a depth of eight (8) feet and four (4) percolation holes to an average depth of thirty-two (32) inches. Percolation tests were performed on October 15, 2014. The Location of the Test Holes is shown on Drawing No. 1A. A Log of Borings is shown on Figure No. 2. The descriptions of the soils and/or bedrock strata are based, primarily, on visual and tactual methods which are subject to interpretation. The percolation test area was established by a representative of CDS Engineering Corporation based on a site plan provided by M3 Construction. Distances from the referenced features were made by taping and angles were estimated. Other than the distances to setback objects indicated on the design documents, no other objects requiring setbacks from the proposed on-site wastewater treatment system (OWTS), as indicated in Tables 30-7-1 and 30-7-2 of the Weld County Regulations, have been located or observed during our exploration. SITE LOCATION AND DESCRIPTION The site is located southeast of Grover, south of County Road 118, on the east side of County Road 95, Weld County, Colorado. The site is generally in a plains region with dirt roads and vegetation had been stripped from the site. The site is relatively flat. No rock outcrops, water wells or other water features were observed at this site. Historically, this site appears to have been used for agriculture. 2 Based on a site plan provided to us by M3 Construction, there do not appear to be any easements on the property. However, we recommend title work be completed prior to construction to ensure the property is clear of easements. From information provided on the County Property Information Portal Maps, this property is not located in a floodplain. At this time we understand that there are not additional improvements planned. SUBSOILS AND GROUNDWATER CONDITIONS Silt — Silts with slight amounts of sand and clay were encountered to the depths explored in the profile hole. The silts appear to be slightly moist, stiff, and light 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. We do not anticipate the high groundwater level to be within four (4) feet of the infiltrative surface. PERCOLATION TEST RESULTS A total of four (4) 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 October 14, 2014, and the test was performed on October 15, 2014. The percolation exploration indicated percolation rates of 54, 69, 120 and 60 minutes per inch with an average percolation rate of 76 minutes per inch. Based on the conditions described above, an Evapotranspiration absorption system should be suitable for this site. It is our understanding that this facility will operate 24 hours a day with no more than five (5) employees on site at any given time. In addition to the employees, 125 trucks per day will come through the site. For design purposes we anticipate 1/3 of the truck drivers (42) will use the restroom facility. 3 INFILTRATIVE SURFACE AREA CALCULATIONS Flow Calculations: 10 employees = 20 GPD/employee = 200 GPD 42 truck drives = 5 GPD/driver = 210 GPD Design Flow = 410 GPD Minimum Septic Tank Size = 1000 Gallons LTAR = 0.20 GPD/square foot (Table 30- 10- 1 , (WCHD On-Site Wastewater Regulations) Adjustment Factors (Tables 30-10-2, 30-10-3, (WCHD On-Site Wastewater Regulations) - Gravity Bed = 1 .2 - Chambers = 0.7 Minimum Area = 2028 sq. ft., See Water Balance Spreadsheet Effective area of chamber: 9.2 sq. ft./chamber Required Number of Chambers = 54 units Type of chamber to be used: *Infiltrator Quick 4 Plus High Capacity *Chamber information based on published material by Infiltrator Systems, Inc. MATERIALS The materials used in construction of the on-site wastewater treatment system shall be new, durable and not subject to corrosion, such as concrete, fiberglass or plastic. All materials shall be installed per manufacturer specifications. All connections between components shall be water tight to prevent leaks and infiltration. Piping Unperforated plastic pipe used in gravity flow beds shall have a nominal diameter of four (4) inches, and a wall thickness of 0. 120 inches, or greater. SDR 35 or Schedule 40 pipe could be used. The piping from the building to the septic tank, and from the tank to the field shall have a minimum fall of /$-inch per foot (`/4 inch per foot preferred). Perforated piping used in the absorption bed or trench shall have a minimum nominal diameter of three (3) inches, and a wall thickness of 0.70 inches, or greater. ASTM D2729 sewer and drain pipe is acceptable for this application. Pipe laid in beds or trenches shall be laid level. The terminal ends of all lines shall be capped or looped with all other lines in the system. Pipe bends shall 4 be limited to 45 degrees or sweeping 90 degree "L"s. Building sewer and effluent lines shall be buried a minimum of one (1 ) foot. All pipe bedding and trench compaction shall be in accordance with the manufacturer guidelines. Septic Tank Septic tanks shall meet the provisions set forth in the county on-site wastewater treatment regulations, and be constructed in accordance with ASTM C 1227. Tanks shall be placed a minimum of five (5) feet from any dwelling or building with a permanent foundation. The tank shall have a minimum of two (2) compartments. Tank size is based on design flow. See Drawing No. 2 for specific tank size. The tank lid shall be able to support a minimum of two (2) feet of soil cover. Tank manufacturer shall provide specifications on maximum cover depth and other design features. These should be provided to the engineer prior to delivery. Access risers shall be provided for each compartment of the septic tank. Risers shall have a minimum 24-inch diameter and extend to, or above, ground level. Riser lids shall have a secure closing mechanism to prevent unauthorized access. Tanks should be sold and delivered by the manufacturer or manufacturer's representative. Distribution Box Distribution boxes shall be placed on solid, level ground to provide uniform distribution of the effluent. The box shall be a minimum of five (5) feet from the septic tank, and be sufficient size to provide outlets for all lateral lines, otherwise additional distribution boxes may be required. Outlet lines shall consist of solid pipe (see piping) for a minimum of five (5) feet. Access to the distribution box shall be provided by a riser, similar to that described for septic tanks. ABSORPTION FIELD The absorption field shall be placed a minimum of twenty (20) feet from occupied or habitable structures or structures with permanent foundations. The field shall be constructed in accordance with this report and the drawings provided. The infiltrative surface and distribution lines, or chambers, must be level. 5 Trenches shall be no wider than three (3) feet; beds shall be no wider than twelve (12) feet. Evapotranspiration Absorption beds are exempt for this requirement. Beds and trenches shall be separated by six (6) feet, of undisturbed soil. Inspection ports, accessible from the ground surface must be installed at the terminal end of each line. The inspection port tube must extend to the bottom of the infiltrative surface and not be connected to the end of the distribution pipe. Where chambers are used, the inspection ports shall be installed per the manufacturer's recommendations, at the end of each line. See Drawing Nos. 2 and 3 for information specific to this project. BACKFILLING AND SITE GRADING All major grading shall be accomplished before construction of the sewage disposal system. Backfilling around septic tanks shall be accomplished before the installation of the piping. Backfill around the tank shall be in a manner to prevent settlement and avoid undue strain on the tank. Positive drainage from, and around, the bed must be provided by sloping, mounding, ditching or berming. CONCLUSIONS The system should be constructed by a licensed septic system installer, in accordance with the County On-Site Wastewater Treatment Regulations. An effluent filter could be installed in or after the septic tank and may provide a longer life for the system. Minimum dimensions and setback requirements specified by the state or county health department regulations shall be upheld. It is the contractor's/owner's responsibility to inform the engineer or health department of anything not mentioned in this report that may impact the performance of the septic system. This system is to meet all rules and regulations set forth by the (Larimer Weld Boulder) County Health Department. The system is to be inspected by a representative of the (Larimer Weld Boulder) County Health Department and Engineer, prior to backfilling. 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 6 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. 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.

Calculation Checks: Water Balance: OK Field Volume Storage: OK Water Level in Field: OK APPENDIX I GENERAL MAINTENANCE RECOMMENDATIONS FOR INDIVIDUAL SEWAGE DISPOSAL SYSTEMS The following minimum recommendations, if followed, should help increase the lifetime of the system: 1 . Septic tanks should be pumped as often as needed based on usage. Generally when the scum layer plus the sludge layer equals 25% of the liquid depth in the tanks, it should be pumped out. 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 within 10 feet of 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. REV 07/23/14 Hello
