The City of ~.~~-~: ~`~ t"~_. ~ '~~ Meridian will use the basis of design report to explore ~ ~ := . ' ; ~~ ~ , partnerships and funding options within its planning process. Design Approach This project involves the creation of a conceptual design for an enclosed negatively aerated composting facility to process 2,000 wet tons per year of biosolids (19% solids) and suitable amendments to achieve an appropriate bulls density, porosity, and moisture content for effective composting. The enclosure is for protection from rain, snow, and thermal heat loss due to wind exposure. It is also for odor control during the first few weeks of the process. The current peak biosolids rate is 111 wet tons per month Qanuary, 2008; annualized to 1,337 wet tons per year for facility sizing). Assuming a 2% growth rate in annual tonnage the compounded increase in tonnage rate in the twentieth year will be 2,000 wet tons per year. The biosolids will be amended with landscape waste, wood waste, and screening "overs" generated within the composting operation from the final screening phase. These amendments will adjust the density, porosity, and moisture content of the feedstock to allow rapid and aerobic composting to occur. Supplemental nutrient-rich effluent is CCPYRIGHi 2t>~ BY CH~i FALL, INC. • CdMAANY CCNRDENrIAI assumed to be added to the feedstock at a maximum rate of 30,000 gallons per month (at a maximum biosolids rate of 167 tans per month at 19% solids). The basis of design will include a concept design that shows truck weighing, material receiving, feedstock preparation, primary composting, secondary composting, aging, screening, final product storage, stormwater control, and operations support (shop, adnvnistration, employee facility, and machinery main#enance). Scope of Work 1. Review client information including biosolids production and characteristics. This will include a review of the proposed site (land area) and a one day meeting with City at the site to identify preferred location, existing utilities, ingress, egress, and surrounding land. uses. This will involve two project team members, including Jan Allen, our subconsultant, and a Civil Engineer from the CH2M HILL Boise office, as well as a representative from Sanitary Service who has experience at a similar facility in Moscow, Tdaho. 2. Review mass and volume balance with City to confirm biosolids rate, facility life cycle, and effluent reuse rate. Discuss with SSC the amount of grass and wood material needed to mix with the City's biosolids. Prepare process design showing facility sizing, volumetric residence time, enclosure size, aeration rate, biofiltration for odor control, machinery sizing, and general sizing of each phase in the process. 3. Prepare a process flow diagram and conceptual site plan showing approximate dimensions of the site and relative size of each phase. 4. Prepare an odor control strategy which includes odor prevention, capture, and control to ncLn;m;~e nuisance odor at the facility. This strategy will ~~nn,ar;~e the causes of nuisance odors in composting as well as design and operational best management practices to m;tL ;tee odor. 5. Prepare a compost product marketing strategy to show how the finished product can be sold, what will be the recommended product specification, who will be the target market, and what the pricixtg strategy should be. Avoided costs such as landfilling costs or saved operating costs by the Parks and Recreation Depar#ment will be specifically addressed. 6. Prepaze a construction cost opinion associated with the conceptual site plan. This cost opinion is intended for planning purposes. The methods used to prepare the estimate include a number of tools and assumptions. Some examples of estimating tools would be cost curves, capacity curves and factors, scale-up factors, and parametric and modeling techniques. Some examples of assumptions would be labor and material costs, competitive market conditions, site conditions, project scope, implementation schedule, staffing, contingencies, special engineering, and other variable factors. 7. Use the cost opinion and machinery sizing to model amortized capital costs, operating costs, and revenues on a year to year basis. This will be presented in a pro forma type spreadsheet showing the break even cost per ton of input and per wet ton of biosolids. COPYRIGHT 2Q~ BY CH2M HILL INC. • COMPANY CONFIDFJ+lML $. Prepare a life cycle cost analysis over a 15 year period using a nominal 4% interest rate, for biosolids disposal alternatives including composting, landfilling, incineration, drying, and land application. Costs will be reported in $/dry ton. This memo will rely on some information from Sanitary Service, who provides local recycling services. We value their experience and willingness to assist on this conceptual design, including a willingness to explore apublic-private partnership in the area of organic waste recycling. As a result of the Moscow facility (designed by CH2M HILL) they have an operating company doing business as Clearwater Composting LLC, a technology licensee of CH2M HILL. Specifically Clearwater can build, own, and operate patented CH2M HILL technologies in the areas of forced aeration, aerated pavement, and biofiltration. This is not a feasibility study to predict financial return on-investment or economic performance. Our work product is a conceptual basis of design memorandum and the work product is limited to providing a reasonable opinion of productivity based on our experience. The report is not intended to be a business plan or economic feasibility study for the prediction of the commercial viability. Special internal procedures and approvals are required for us to agree to provide an economic feasibility study. If a client requests such an economic feasibility study this carries more risk to CH2M HILL and therefore must be priced to fully address the costs and risks therein. This would include but not be limited contractual limitations, report disclaimers, and peer review of the work product. Assumptions and Limitations The unimproved site will be graded and paved so it can withstand repetitive front end loader activity. It will also have a runoff system that quickly removes rainfall from the working surface. Permit applications, meetings, and liaison with agencies are not included in the work scope at this time due to the unknown level of effort involved. Any and all applicable fees, assessments, permits, engineering calculations, plans, taxes (whether sales, excise, properly, use or other taxes) are not part of this scope. No analytical odor evaluation, measurement, modeling, or odor panel work is included in the proposed approach and scope of work. Utilities, e.g. power, water, wastewater, stormwater, telemetry, etc., are assumed to already exist at the site. Motor horsepower for each motor will be specified but no power distnbution design is necessary due to the simplicity of the work. No surveying is included in this scope of work. It is assumed the site has adequate soil strength to support the proposed improvements. I£ poor soil conditions exist additional scope of work to thoroughly address geatechnical issues will need to be agreed upon with City of Meridian. No condensate or wastewater systems are included in this design and these flaws are assumed to be drained to the existing wastewater treatment headworks. Remote control and monitoring of the system by modem and computer connection is not included in this design or this agreement. Public hearing attendance, community relations, or other similar services are not included in this scope of work. Specific Exclusions: a. All geotechnical investigation, design, foundation design, and field work b. All permitting, permit applications, and permit correspondence c. All utility investigations, rates, service requests, and utility correspondence CGPYRIGHT' 20~ BY GH2M FflU., ING. • COMPANY CONFlDENTIAL d. Characterization of wastewater, effluent, and biosolids e.

All field woxk (this is a desktop study) Attachment 6 Compensation Period of Performance: The period of performance will be from January, 2009 through May, 2009. Level of Effort and Deliverables: CH2M HILL will provide labor and materials necessary to perform a desktop study for the City. The deliverables associated with this work is a conceptual design memorandum. Proj ect Budget: A not to exceed budget of $22,082 is established for this scope on a time and material basis.
