September 8, 1997
4:30 p.m.
Large Conference Room
Members present: Mayor Rooff, Getty, Krizek, Anders, Mollenhoff,
Jordan, Murphy, Collier.
Moved by Mollenhoff, seconded by Krizek that the Agenda, as
proposed, be approved. Ayes: Four. Absent: Jordan, Murphy,
Collier. Motion carried.
The Professional Services Agreement with RUST Environment &
Infrastructure, Inc. in conjunction with the Lagoon Bio -Gas
Recovery System Project and the request of the Administrative
Director to proceed with Phase I, Preliminary Design, was reviewed.
The cost of the preliminary design is $70,000 and will be paid from
the sewer fund. The Project consists of the construction of new
facilities at the Northeast Anaerobic Treatment Facility (NATF) to
clean and compress the bio -gas from the NATF for sale as a vehicle
fuel and for sale to the local natural gas utility. The NATF
produces an average of 539,000 cubic feet per day of bio -gas, which
is currently flared to the atmosphere. Previous studies have
suggested the feasibility of cleaning the bio -gas of contaminants
in order to bring the methane content up to natural gas pipeline
standards. The clean bio -gas would be compressed and metered into
the nearby natural gas distribution pipeline, either for direct
sale to the natural gas utility, or for transport to a future
compressed natural gas vehicle fueling station constructed in
Waterloo. The Preliminary Design Phase culminates with the
preparation of the design documents to approximately 30 percent
design completion. The purpose of the Preliminary Design Phase
includes the following:
1. Confirm the suitability of NATF bio -gas for the cleaning
process.
2. Confirm the reliability of the gas cleaning technology.
3. Determine the size and layout of the new gas cleaning
facilities at the NATF.
4. Prepare a conceptual cost estimate.
The preliminary design documentation will provide the city with the
information necessary to budget and schedule the actual
construction of the project as well as confirm that the system will
perform as expected after startup.
The total project cost for the Bio -Gas Recovery System is
$6,680.00. This cost includes 117 diesel conversion kits at $8,300
each and 252 gasoline conversion kits at $4,200 each.
Bob Bamsey from RUST Environment & Infrastructure stated that no
other community is using bio -gas from a treatment facility. There
are other systems in place using bio -gas, mostly from landfills.
Councilperson Getty questioned if after the study is completed will
the project be brought back to the council for final design. Bob
Stevenson, Administrative Director, responded that the results will
be brought back to the council and that the city will be
investigating funding for the project, including the conversion
kits.
Moved by Mollenhoff, seconded by Anders that the Professional
Services Agreement with RUST Environment & Infrastructure, Inc. be
approved and the Administrative Director be authorized to proceed
with Phase I, Preliminary Design with an April 1, 1998, in
conjunction with the Lagoon Bio -Gas Recovery System Project. Ayes:
Four. Absent: Jordan, Murphy, Collier. Motion carried.
An application for Congestion Mitigation/Air Quality (CMAQ) funding
for the Lagoon Bio -Gas Recovery System was reviewed.

Jordan now present at 4:43 p.m.
Bob Stevenson, Administrative Director, stated that the Iowa
Northland Regional Council of Governments (INRCOG) is preparing a
grant application to the Iowa's Clean Air Attainment Program for
CMAQ funds. Vehicle conversion kits, which are necessary to allow
existing fleets to use the compressed natural gas (CNG), are
estimated at $2,030,000, cost for the facility is estimated at
$4,080,000 and a contingency of $570,000 to cover legal,
engineering and administrative costs for a total project costs of
$6,680,000. The city will be required to furnish a 20 percent
match, which can met using sewer funds. The deadline for the
application is October 1, 1997. Construction could start within
one year and take a year to a year and a half for completion.
Councilperson Murphy now present at 4:46 p.m.
Dick Grimm, Superintendent of Sanitation/Recycling, updated the
council on the recycling program. The cost for the city's
recycling program has increased dramatically. The recycling cost
for April through May 1997 averaged $24,436, and last year over the
same period the cost averaged $16,024. Due to increased usage at
the drop off sites and demands by the businesses where the drop off
sites are located to increase service and the cleaning of the
sites, we have increased our contract with Corkery for Saturday and
Sunday service at premium labor costs.
Representatives from Corkery stated that the cost per ton is
determined by the cost to sort the material and whether the
materials are contaminated. Materials collected from households
are not high valued. There is more contamination with drop off
sites.
Councilperson Anders suggested an educational program on recycling.
Corkery suggested that funds be solicited from the Black Hawk
County Landfill Commission to be used for an educational program.
Mayor Rooff stated that it may be necessary to implement a curbside
recycling program if the costs for the drop off sites continue to
rise.
Ideas that were suggested included: hiring someone to police the
sites, using prisoners to clean the drop off sites, reducing the
number of days that the material is picked up from the drop off
sites, hiring retirees and educating the public.
Corkery reported that seven counties are using co -mingled curbside
recycling programs and they have been well accepted. There is
approximately a 50 percent diversion from the landfills. Some are
using landfill money to help pay for curbside recycling.
Councilperson Collier now present at 5:15 p.m.
Mayor Rooff stated that our costs for drop off sites has increased
17 percent over four years. The city has increased the number of
sites from seven to eleven.
Councilperson Jordan asked what system works better, curbside
recycling or the drop off sites. Corkery reported that a private
contractor can provide the services at less cost than the city and
cheaper than the current drop off site system. The city has
outgrown the drop off sites, and the level of services has
increased at an increased cost.
Mayor Rooff stated that staff needs to investigate what it would
take to keep the sites clean at a cost cheaper than the services
Corkery currently provides. Superintendent Grimm was instructed to
gather information and provide the information to the Public Works
