Dear Mr. Brown: As requested by Paul Rutledge with Sopris Engineering, LLC, Hepworth - Pawlak Geotechnical, Inc., performed percolation testing at the subject site. We previously conducted a subsoil study for the proposed residence and presented our findings in a report dated April 23, 2002, Job No. 102 225. A profile pit and two shallow backhoe pits were excavated on May 13, 2002 at the locations shown on Fig. 1. The test holes (about 2 feet in diameter by 1 foot deep) were hand dug at the bottom of shallow backhoe pits and were soaked with water one day prior to testing. Screened rock was placed in the bottom of the test hole prior to soaking. The subsoils exposed in the percolation holes are similar to those exposed in the Profile Pit and consist of about 2 feet of topsoil overlying medium stiff sandy silty clay to the pit depth of 8 feet. Groundwater was encountered in the pit at a depth of 5 feet and the soils were moist to wet below the water. Percolation testing was conducted on May 14, 2002, by a representative of Hepworth - Pawlak Geotechnical, Inc. The percolation test results are summarized on Table I. The percolation test results indicate an infiltration rate of 20 minutes per inch. Based on the subsurface conditions encountered, primarily the shallow groundwater conditions, we recommend a civil engineer design the septic disposal system. If you have any questions or need further assistance, please call our office. Sincerely, I • • O�i��EiSs•ai_ 1 Jordy Z. Adamson,/Jr., �° 29707 Rev.

This design is based on our evaluation of the site conditions with information provided by others for use in supporting your application to Garfield County. Our recommendations are in accordance with Garfield County and the State of Colorado ISDS Regulations. Garfield County must permit any proposed improvement to the site. We have reviewed the information forwarded to us, conducted a site visit, formulated an ISDS design and created a site plan with construction details as part of our scope of work. Conclusions Based on our findings we believe that the design and installation of an approved ISTS system is feasible in accordance with the Regulations of Garfield County and the State of Colorado. We recommend that a new 1500 -gallon septic tank equipped with an approved wastewater treatment unit installed in the tank per Association standards. The treated effluent will discharge to a distribution box to be equally distributed across a 500 square foot soil dispersal field system. The soil dispersal system can be installed in natural soils and needs to be located within the building envelope down gradient of the proposed house, as delineated on the attached plan. The system will meet all required setbacks and be installed within the general boundaries indicated on the plan. Our Design is outlined below and delineated on the attached site pian. Site Location The subject site is located in the Cerise Ranch Subdivision at Lot 5, on the south side of Larkspur Drive in Garfield County, Colorado. The site is situated in Section 32, T 7 S, R 87 W of the 6`h P.M. The Site comprises approximately 2 acres. The site is bounded on the east and west by adjacent undeveloped single-family lots (6 & 4 respectively). 502 Main Street • Suite A3 • Carbondale, CO 81623 • (970) 704-0311• Fax (970) 704-0313 Sums ENGINEERING LLC civil consultants Chuck Brown SE Job No. 22060.01 June 25, 2002 Page 2 Existing Site Conditions The site is located on previously undeveloped, irrigated agricultural lands. The site has a gentle slope (1%) toward the southeast toward the existing drainage ditches and Blue Creek. The existing ground surface in the proposed septic area has an approximate slope of 1%. The site has been regraded and was previously covered with hay fields and pasture grasses. Domestic water will be supplied by a central water system. The majority of the lot is delineated as a common area/open space or easement. A relocated drainage ditch and easement runs across the Southern section of the lot approximately 25 feet south of the southern building envelope line. Proposed Site Conditions It is our understanding that you intend to construct a 3500 SF, two-story, 3 -bedroom single-family home with an attached garage. The maximum number of rooms that could be utilized as bedrooms in the structure is 4. The proposed improvements will include a new ISTS system with appropriate site grading. The new structure is to be generally located as shown on the plan. The site is required to have an engineered sewage treatment system to be installed and maintained in accordance with specifications and regulations approved by the Homeowners Association and the covenants of the subdivision approved by Garfield County. Basis of Sewage Treatment System Requirement Pursuant to Section 4.15 Wastewater Treatment contained in the Declaration of Covenants, Conditions, Restrictions and Easements for the Cerise Ranch Subdivision (Covenants) certain provisions for the design, installation and maintenance of ISTS for individual lots are required. " Wastewater treatment shall be supplied to each Lot by individual sewage treatment system (ISTS) installed by each Owner in accordance with the ISTS Design and Performance Standards set forth in Section 17.1.D. and maintained by the Association in accordance with the provisions of the ISTS Maintenance Plan set forth in Section 9.4. The Association shall be responsible for setting all rates, fees or charges for inspecting, maintaining and repairing each individual system and such rates, fees or charges assessed by the Association against each lot for such inspection, maintenance and repair shall be a personal obligation of the Owner thereof which the Association shall have the power and duty to enforce." Development of the site's ISTS will be in accordance with the above referenced design and Performance Standards. It is our understanding that a standard system(s) may be adopted for use on all the lots within the subdivision. The approved system will be installed in a standard concrete septic tank with minor modifications. We recommend installing the Orenco Systems Advantex-AX-20 unit. The Orenco Systems Advantex unit is an approved treatment system. Chuck Brown SE Job No. 22060.01 June 25, 2002 Page 3 Subsurface Conditions Attached herewith are the results of the subsurface investigation and percolation tests conducted on April 4 2002 and May 14, 2002 by Hepworth-Pawlak Geotechnical, Inc. The reports are dated April 19, 2002 and May 31, 2002 (Job Number 102 224). The subsoil encountered at the site consists of 2 foot of topsoil overlying medium stiff, sandy silty clay. Relatively dense, slightly silty sandy gravel with cobbles and boulders was encountered beneath the clay at depth of 10 to the profile boring depth of 14 feet. Groundwater was encountered at 6.5 feet in Boring 1, located in the northwest comer of the site and at 5 feet in Boring 2, located in the southeast comer of the site. HP performed an additional subsurface investigation and percolation test on May 14, 2002. A profile pit and percolation test holes were excavated on May 13, 2002. The percolation test resulted in an average percolation rate of 20 minutes per inch. Design Criteria The proposed single family home contains 3 bedrooms. The minimum design requirement at Cerise Ranch is 4 bedrooms. The design flow is calculated as follows: Single family home — equivalent 4 bedroom population @ 2 person /bedroom = 8 persons. From the Garfield County I. S. D. S. Regulation; Max. Design flow (Qd) = # of people x (avg. flow) x 1.5 gal/person/day. Gallons per day per person for the subject house = 75 gal/person/day Assume 8 people daily population Qd = 8*75*1.5* =900 gal/day Septic Tank Design Based on Design Flow Qd. Qd = 900 gal/day Volume (V) of tank = Design Flow * 1.25 (30 hour retention time) V = 900 gal/day * 1.25 days =1125 gallons To provide for future changes in use of the facility and accommodation of the treatment unit we recommend a minimum tank size of 1500 gallons. Use one 1500 -gallon, concrete, dual compartment septic tank. Chuck Brown SE Job No. 22060.01 June 25, 2002 Page 4 Treatment System Criteria Pursuant to Section 17.10, in the Covenants, the engineered system shall be designed to service at least (4) bedrooms utilizing an approved advanced treatment system. The advanced treatment system may be a recirculating trickling filter, sequencing batch reactors and/or other accepted on-site wastewater treatment system technologies. The system shall be capable of producing effluent quality which meets or exceeds the requirements of the US EPA for secondary wastewater treatment (30mg/L BOD and 30 mg/L suspended solids). All dispersal fields shall be sized to adequately service (4) bedrooms. All ISTS components shall be accessible from the surface to facilitate system testing and maintenance. Appropriate isolation valves or a distribution box is required. We recommend installing the Orenco Systems Advantex-AX-20 unit. Treatment System Desien With respect to effluent quality, maintenance and operation requirements, a compact recirculating trickling packed bed filter treatment system packaged in and on a new concrete septic tank is the preferred method of treatment. The Orenco Systems Advantex-AX-20 is a "State of the Art" pre -manufactured package system that provides economical, quiet, odor free operation that provides excellent wastewater treatment, which exceeds the requirements of the EPA for secondary wastewater treatment. Raw sewage inters a standard 2 -compartment septic tank for conventional primary treatment. Clear zone effluent is filtered and pumped to a distribution manifold in the Advantex filter pod via a pump/filter vault assembly installed in the secondary septic tank compartment. Effluent percolates down through textile media and is collected in the bottom of the filter pod. The vertical textile media provides approximately 40,000 SF of surface area for bio -mat attachment. The treated effluent is discharged out of the filter pod to a recirculating splitter valve (RSV) which, splits the flow between return flow back to the septic tank and flow to the dispersal/absorption field. During periods of no sewage loading all of the discharge is returned to the tank. The return flow is discharged back to the secondary compartment or if nitrogen removal is desired the return flow is discharged back to the primary compartment. The Advantex recirculating pump typically runs only 90 minutes per day. The Advantex AX -20 is designed to provide treatment resulting in effluent water quality parameter levels of 15 mg/L BOD and 15 mg/L TSS based on typical residential strength wastewater. Assuming an average BOD concentration of 150 mg/1 the unit will remove 90% of BOD and up to 85% total nitrogen removal. The Orenco Systems Advantex AX -20 is adequate to treat wastewater from an equivalent 5 -bedroom home utilizing a 1500 -gallon septic tank. Effluent Dispersal System Desigm Treated effluent is discharged to the ground via a soil infiltration system allowing the infiltration of treated effluent into the soil. The infiltration/dispersal field is sized adequately to maintain long-term acceptance of the treated effluent into the ground. We do not anticipate that a conventional bio mat will form on the bed surface. The bed will provide a means for achieving tertiary treatment (polishing). However for sizing the infiltration/dispersal system we are utilizing the guidelines approved by the State of Colorado for sizing of an absorption field. A soil infiltration/dispersal bed system, utilizing gravelless chambers is recommended. The chamber units may be installed in native soils. The State allows a maximum 40% area Chuck Brown SE Job No. 22060.01 June 25, 2002 Page 5 reduction for the use of gravelless infiltration chambers in a bed configuration. Based on the hydraulic loading rate of the receiving soils and the absence of a conventional bio -mat on the infiltrative surfaces in the field we estimate that the long-term recovery rate of the daily peak loading will be less than 2 hours. Soil DisuersaUInfiltration Field System Desi¢n The average slope in the septic envelope location, just north of the building site, is 1 %. The size of the infiltration bed is based on the average percolation rate of 20 minutes per inch. Based upon the design percolation rate, the standard absorption area equation is: A (SF) = Qd *(t)/' : where A = Area; Qd = Design flow (gal/day) 5 t = time in minutes This design calculation results in a recommended minimum absorption area: A= 900 *(20) 805 so. ft. 5 Apply a 40% reduction for utilizing gravelless infiltration chambers. 805 x 0.6 = 483 sq. ft. Use 4196 SF of bed with gravelless chambers: Assume Moot wide by 6.25 -foot long chamber units. Assume 15.5 square feet per chamber: 483 sq.ft. = 31 chambers. Use 32 chambers for 496 SF. 15.5 sq.ft/chamber We recommend using a bed system composed of 2 beds with 2 rows each 50 feet long and 6 feet wide, containing 8 standard infiltration chamber units in each row. Excavate dispersal field to accommodate a minimum 500 SF of interior surface area. This design is conservative based on the estimated recovery rate and the high quality of effluent applied to the bed. Effluent Distribution System A gravity distribution system will be utilized to transport effluent from the new septic tank and treatment system and to the infiltration field's leaching chambers. An effluent filter pump system vault will be installed in the secondary compartment of the septic tank to circulate filtered effluent through the packed bed filter treatment media above the tank, which will greatly reduce the biological loading to the infiltration field. An automatic float operated discharge valve opens per demand to allow treated effluent to be discharged to the field. A 4" effluent discharge line will discharge effluent to a distribution box installed near the down -gradient infiltration bed field. The effluent will be equally distributed from the distribution box through 4 individual discharge pipes to each pair of chamber rows in the system. The discharge pipes will connect to a tee at the head of each chamber row pair. An inspection port should be installed on the top mid -point cut out on the end chambers in each row. Chuck Brown SE Job No. 22060.01 June 25, 2002 Page 6 Control Systems An Orenco Systems control box will control all functions and monitoring of the installed system. The controls will record all operational cycles and will make adjustments if necessary. Alarms for the treatment system components in the septic tank will be recorded and reset through the control box. A Vericomm Telemetry control will be installed with the control box to allow offsite monitoring, data collection and remote operational setting control. Each system at Cerise Ranch will be set up with this web -based technology for use by authorized operators. ISTS Operation and Maintenance Pursuant to Section 9.4, ISTS Management Plan, in the Covenants, the engineered system shall be inspected on a regular basis and be properly maintained. Ownership of the system and responsibility for construction, repair and maintenance will remain with the Lot Owner. The Association shall retain the services of qualified personnel to inspect the ISTS's and to perform all maintenance and repairs necessary to ensure that the system is installed properly, is in good operating condition and is in compliance with the performance requirements set forth within Section 17.1.1). The operating components of the ISTS system will be inspected within 30 days of being placed into operation and thereafter at least quarterly. The treated effluent being discharged shall be sampled and tested for BOD and TSS content at least biannually. Administration of these requirements is delineated in Section 9.4. Attached is a copy of a maintenance agreement with SCG Enterprises the company that will install the system. The ISTS system should require minimal maintenance. Several factors influencing the need for maintenance include: actual wastewater flows versus design flows, the volume of kitchen/domestic waste (excluding human waste and toilet paper), excessive household chemicals and other toxic liquids. The tank, dispersal field and other applicable treatment system components should be visually inspected bi- annually for debris, wear, damage, leaks, or other potential problems. In general, for a properly utilized system, septic tanks should be pumped and inspected every 2 - 4 years. The effluent filters should be cleaned every six months and at the time of pumping. Dispersal fields should be maintained with suitable cover and kept free of root invasive plants. Positive surface drainage away from the infiltration field should be maintained. Attached are an ISDS and Advantex operation and maintenance guide. Construction and Inspections Prior to construction of the permitted system the engineer should be contacted by the contractor and owner well in advance to provide adequate time to discuss the system components with the contractor, answer questions, resolve any conflict issues and schedule inspection site visits based on construction progress. County Regulations require that the Design Engineers of record perform site inspections of the permitted system during construction and provide "As -Built" documentation of the installed system to the County after construction is complete. Chuck Brown SE Job No. 22060.01 June 25, 2002 Page 7 General Notes 1) All materials and installation practices shall conform to the Garfield County Individual Sewage Disposal Regulation. 2) All sewer lines and distribution lines in the system shall be 4" Schedule 40 or SDR -35 PVC unless specified otherwise on the plans. 3) Add a two-way clean out on the service line from the house. 4) The system shall be plumbed to distribution effluent into the bed with equal distribution. 5) The contractor shall ensure that the concrete septic tank and sewer lines are watertight. 6) The trench area must be protected to prevent damage from vehicular or livestock traffic and must be crowned to divert drainage runoff away from the trenches to minimize surface infiltration. 7) The infiltration chambers shall be installed level in the bed. The top of the backfill over the chambers shall be covered with filter fabric or other suitable pervious material to prevent the migration of fines from the overlying topsoil layer. 8) The field must have a minimum cover of 12 inches. A final cover of topsoil suitable for vegetation, a minimum 4" deep, shall be placed from the top of the pervious cover layer to the finished surface grade. 9) The dispersal field must be sodded or covered with vegetative ground cover. 10) The treatment unit shall be installed by in accordance with the manufactures specifications and installation guidelines by qualified personal. Our design and recommendations are based upon data supplied to us by others. If subsurface or site conditions are found to be different from those presented in this report, we should be notified to evaluate the effect it may have on the proposed ISTS. If the County Environmental Health Department requests changes or modifications to this design, we should be contacted to evaluate the effect on the ISTS.
