Scope of Work
Conceptual Design for an Organic Waste Composting Facility
Project Understanding
The project involves consultation on the development of
anew co-composting facility for the City of Meridian.
The City has a potential site just west of their wastewater
treatment facility {western land area is approximately
1,250 ft x 600 ft; and 17 acres}. The facility would accept
dewatered biosolids and landscape waste to produce a
commercially valuable soil product. Compost will be the
primary product, but other products like mulch and
manufactured topsoil could follow, depending upon the
final marketing strategy. The wastewater operations
may also provide nutrient-rich effluent (containing
nitrogen and phosphorus) to irrigate and enhance the
composting process. Economics, product quality, and
odor control are the three primary success factors.
CH2M HILL will provide a basis of design to address
these success factors and show how the facility would
look and operate within the potential site. The City of
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 bulk 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 (January, 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-xich effluent is

asstuned to be added to the feedstock at a maximum rate of 30,000 gallons per month {at a
maximum biosolids rate of 167 tons 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,
administration, employee facility, and machinery maintenance).
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 a#fice, as
well as a representative from Sanitary Service who has experience at a similar
facility in Moscow, Idaho.
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 minim;~e nuisance odor at the facility. This strategy will summarize the
causes of nuisance odors in composting as well as design and operational best
management practices to minimize 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 pricing strategy should be. Avoided costs such as
landfilling costs or saved operating costs by the Parks and Recreation Department
will be specifically addressed.
6. Prepare a construction cost opinion associated with the conceptual site plan. This
cost opinion is intended for planning purposes. The methods used to pxepare 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 yeax 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.

$. Prepare a life cycle cost analysis over a 15 year period using a nominal 4% interest
rate, for biosolids disposal alternatives including composting, IandfiIling,
incineration, drying, and land application. Costs will be reported in $/dry tan.
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 farted 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 finis 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 wrill 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, property, 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, wastewatex, stormwater,
telemetry, etc., are assumed to already exist at the site. Motor horsepower for each motor
will be specified but no power distribution 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. If poor soil conditions exist additional
scope of work to thoroughly address geotechnical issues will need to be agreed upon with
City of Meridian. No condensate or wastewater systems are included in this design and
these flows 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 corxespondence
c. All utility investigations, rates, service requests, and utility correspondence
