ITEM TITLE: Resolution Authorizing Execution of Containerized Composting
Pilot Project
SUBMITTED BY: Chris Waarvick, Wastewater Superintendent
Bruce Bates, Assistant Superintendent
CONTACT PERSON/TELEPHONE: Chris Waarvick/Bruce Bates, 575-6078
SUMMARY EXPLANATION:
The City of Yakima, in accordance with their 1993 updated Biosolids Management Plan
and Best Management Practices, is examining other options for biosolids utilization.
Currently all biosolids are dewatered and treated to a Class "B" level which is
acceptable for agricultural use on Health District permitted sites. These sites, which are
primarily hop fields, are closely supervised by the City according to State, Federal and
Local regulations, resulting in unavoidable costs from field monitoring, laboratory tests,
sampling, and administrative overhead. One alternative to the strict regulations which
accompany agricultural sites which receive Class "B" biosolids, is the production of
Class "A" compost. Class "A" compost was produced at the Yakima Facility last year
during some pilot tests. Forage grasses were also included in the compost mix which
resulted in significant odor generation. These tests took place in an open environment
utilizing the aerated windrow method. This led to numerous odor complaints from the
surrounding neighborhood. The proposed agreement with Green Mountain
Technologies will utilize enclosed containers with odor containment and treatment
therefore, eliminating the objectionable odors. This activity was contemplated in the
1996 adopted budget in concert with preparing an updated Biosolids Management
Plan.
Through this contract with Green Mountain Technologies, staff will gather more
information on the best methods to produce a viable, odor free compost product.
Given this information, staff should be able to determine improved cost effective
methods for biosolids utilization. Cost for this contract is not to exceed $12,000 and is
budgeted in the 478 fund, Project #1752.

INFORMATION ITEM
January 26, 1996
.To: Honorable Mayor, Members of City Council, and City Manager
From: Chris Waarvick, Wastewater Superintendent
Regarding: Containerized Composting Trials
Summary
For over two decades Yakima's class "B" biosolids have been
successfully utilized on agricultural lands. The land application sites are
permitted by the Yakima Health District following an extensive
environmental review. Before application of biosolids to the farmer's
land, background levels of micro -nutrients in soils and near -by wells are
determined. The residual available nitrogen in crop soil and the crop
nitrogen requirements are used to calculate biosolids application rates.
However, due to regulatory and market uncertainty, a composting pilot
project was conducted in 1995. Composting of biosolids creates a product
which minimizes application site monitoring costs, reduces the potential
for presence of microbial pathogens, and ultimately could make the
biosolids available for general public distribution. Carefully controlled
composting trials are scheduled for 1996 to provide data for inclusion
into an updated Biosolids Management Plan.
Discussion
Biosolids are a by-product of municipal wastewater treatment.
Early in the treatment process, settleable -solids are removed from the
liquid waste stream through primary clarification. The liquid and solids
waste streams are then treated separately. At the Yakima Wastewater
Treatment Facility, solids are treated through the anaerobic digestion
process, a biological process which stabilizes the biodegradable solids.
After stabilization, the solids are thickened or "dewatered" in a sludge
centrifuge, and stockpiled at the treatment plant for beneficial reuse as a
fertilizer and soil amendment on agricultural land. Biosolids are
classified by federal regulation (CFR 40 part 503) as either a class "A"
biosolids or class "B" biosolids. CFR 40 part 503 stipulates that
biosolids must meet vector attraction reduction, volatile solids reduction,
metal levels and pathogen levels to be classified as a Class "A" biosolids.
Dewatered Yakima biosolids can only meet three of the four levels
required for a Class "A" product, which makes Yakima's biosolids a Class
"B" biosolids.
page 1
Although our class "B" biosolids program continues to be successful,
we believe it is important to continue to explore and develop alternative
biosolids processes such as composting. This is important because the
Class "8" market is not completely guaranteed and regulations may
become more onerous. Site application regulations for a Class "B"
biosolids are more stringent than for Class "A" biosolids.
To explore other markets, reduce regulatory oversight that govern
Yakima's biosolids and possibly reduce costs, we have experimented with
composting. Composting is an aerobic process that relies on micro-
organisms. The metabolic process of composting creates enough heat to
reduce the pathogen levels of the composted biosolids to make them a
Class "A" product. The heat comes from the activity of the micro-
organisms in the composting process. Composting produces a rich humus-
like soil additive that plants thrive on. The compost helps retain wager in
the soil, thereby conserving water. Bulking agents used in compost may be
clean, recycled community waste by-products, but optimally are clean
wood chips. The City has an approved composting site plan from the
Yakima Health District. This plan also received SEPA review in 1995.
For a class "A" biosolids product (compost), the monitoring i s
performed at the plant, while class "B" biosolids require additional,
extensive monitoring at the application sites. The compost process
is monitored for length of time at sufficient temperature for ;pathogen
reduction. Complying with EPA 503 regulations ensures that Class "A"
compost is safe for use. Development and utilization of an agricultural
site for class "B" biosolids application requires extensive laboratory
testing on soil and water, and entails considerable site management
responsibilities. Irrigation run-off water from the application sites are
monitored for nitrogen leaching and fecal coliforms.
Composting
This past spring and summer we experimented with vvindrow
composting at the treatment plant. See attached approved composting
permit and DNS of composting project. Windrow composting is one of the
simplest methods of composting, done in the open air with a minimum of
equipment. It starts by piling the bulking agents, usually wood chips, and
the biosolids in a row and mixing them. Air (oxygen) is introduced iinto the
compost pile by turniing the pile. We tracked the length of time required
for the compost to meet EPA 503 rules for temperatures and pathogen
reduction. Grasses were composted from the Industrial Waste Sprayfield
with ground yard wastes and biosolids in an effort to reduce grass
page 2
disposal costs. Unfortunately, the amount of grass added caused the
compost mix to become out of balance, excessive odors were created, and
neighbors objected strongly to our operation. Subsequent discussions
with composting professionals revealed that the presence of grass was
the main cause of odors in the compost. To control odors, different mixes
and/or different composting techniques may be employed. At the end of
the 1995 composting season, Yakima had produced a quality compost that
met all the requirements for EPA 503 Class "A" product. Part of the
compost was applied to the Industrial Waste Sprayfield and some was
donated to the Yakima Greenway to improve soil conditions.
Proposed Composting Activity for 1996
In an effort to meet our composting objectives and still be good
neighbors, we propose to test a containerized composting pilot project
this spring (see attached brochure). Containerized composting is different
from windrow composting in that air must be forced through the compost.
It is similar to static pile composting, where the pile has air forced
through it and the pile is not disturbed until the pile has finished
composting.
The compost mix is placed inside an enclosed container that has
perforated piping inside it. After the container is filled, a blower unit i s
installed on the end of the piping to blow air into the compost for the
micro-organisms. Exhaust air is piped to a biofilter to remove any odors.
The biofilter is a pile of mature compost that has micro-organisms in i t
that use odors for food. The compost is monitored for length of time i t
meets the required temperature to kill pathogens and be classified as a
class "A" product.
The containerized compost pilot project is estimated to cost $5,000
for a 12 week test. The adopted 1996 budget has funds appropriated for
expenses incurred in the updating of the Biosolids Management Plan. Upon
completion of the test we should have the following information.
• Can containerized composting produce a Class "A" product
without excessive odors?
• Can spray field grasses be mixed with the compost without
causing odors and still meet Class "A" standards?
• Is the system a viable alternative to other forms of static pile
composting?
• How does this compost method compare in cost, staff
requirements and operation and maintenance when compared to
Class "8" biosolids production and other composting methods?

This information will be utilized to amend the 1993 Yakima
Biosolids Management Plan. The updated plan will provide direction and
guidance for the next decade on residuals management.

Meeting Composting Demands in the 90's
The Containerized Compost System provides affordable state-of-the-
art composting for small operations. The sealed in -vessel design
controls odors and collects leachate. The computerized aeration
system reliably meets and records EPA temperature requirements
while minimizing odor generation. The complete turn -key system
includes integrated mixing, loading and screening equipment to
minimize capital and operating costs.
The Comploader TM'
Preparing the right mix is essential for composting.
The CompLoader tums shredding, mixing and
loading into a one step process. Load the hopper
with biosolids or food waste and bulking agent. The
mixing augers shred and blend the material then load
it into the CompTainer. Weight scales indicate the
amount of each ingredient for the perfect compost
recipe. High energy flails at the end of the conveyor
break up dumps and uniformly load the CompTainer.
The CompTainer TM
Rain or snow won't affect composting! The
CompTainer is a modular, air tight composting vessel.
The design begins with a stainless steel aeration floor
to evenly distribute pressurized air while capturing
leachate. Walls are insulated and covered with
durable liner to prevent corrosion and freezing. With
no moving parts to maintain, the CompTainer is
simple and reliable to operate. Compost is loaded
through a gasketed door or an optional removable
cover. The CompTainer uses standard roll -off trucks
for unloading and transport, giving enormous
flexibility to facility design and operation.
•
Aeration and Odor Control
Maintaining aerobic conditions and minimizing
exhaust air are the keys to odor control. The aeration
system captures all the compost exhaust air for
treatment in a biofilter or recirculation back to the
CompTainers. Biofiltration is an inexpensive
biological process proven effective for compost odor
control. A heat exchanger and dampers are used to
rapidly heat up the mix and maintain a uniform
temperature in each CompTainer. The aeration
system and biofilter can be installed in a roll -off
container to make the entire system transportable.
le Containerized Composting Process
compostable material is loaded into the CompLoader where it
shredded and mixed with bulking agent. The CompLoader
iveys the mix into the CompTainer. Once full, the operator
ses the CompTainer, attaches; the aeration lines and inserts the
iperature probes. The CompTroller regulates sterilization during
to 24 days of active composting. The CompTainer is picked up
a roll -off truck and dumped at the product storage area. The
npost may be screened to recover bulking agent and improve
compost product.
