SUBJECT: Resolution to Dispense with Formal Bid per Public Contract Code Section 3400,
and Petaluma Municipal Code Section 4.05.050 for Acquisition of Bio- methane
Processing Equipment and to make a Sole Source Finding for the Equipment
Acquisition in Conjunction with the Biomass -to- Biofuel Project at Ellis Creek
Water Recycling Facility
RECOMMENDATION
It is recommended that the City Council adopt the attached Resolution to Dispense with Formal
Bid per Public Contract Code Section 3400, and Petaluma Municipal Code Section 4.05.050 for
Acquisition of Bio- methane Processing Equipment and to make a Sole Source Finding for the
Equipment Acquisition in Conjunction with the Biomass- to- Biofuel (B2B) Project at Ellis Creek
Water Recycling Facility.
BACKGROUND
The City's Ellis Creek Water Recycling Facility ( ECWRF) has been in operation since early
2009 and currently processes an average dry weather daily flow of 4.8 million gallons per day.
As described in previous Council meetings, wastewater loading increases and the need for
process redundancy require the City to add a second anaerobic digester and other ancillary
improvements. The second anaerobic digester at the ECWRF is currently under construction
with a projected completion in summer 2017.
The California Energy Commission (CEC) grant program, the Alternative and Renewable Fuel
and Vehicle Technology Program for Pilot -Scale Advanced Biofuels Production Facilities (PON-
13 -609), promotes the development of new California -based biofuel production facilities that can
sustainably produce low carbon transportation fuels. The anaerobic digestion of biosolids
produces biogas that can be cleaned to produce biomethane, which can be compressed to create
compressed natural gas (CNG) which can be used to fuel vehicles. In March 2014, the City
submitted an application for a $3 million grant to the CEC for the design and construction of a
biomethane production facility, a CNG fueling station, and related site improvements at
ECWRF. The funding required a minimum 50% match from local funds. The total cost of the
B2B improvements, including the anaerobic digester and appurtenant facilities, CNG production
facilities, and the high strength waste facilities, is $15,300,000. In November 2015, the City was
advised the 13213 project had been selected for funding. On January 4, 2016, the City Council
approved Resolution N.C.S. 2016 -008 authorizing the City Manager to execute all necessary
application documents and to negotiate and execute a financial assistance agreement with the
CEC and any amendments or change orders thereto. On March 9, 2016, the City was awarded a
$3 million grant by the CEC for the 13213 project.
With the addition of a second digester, ECWRF will have sufficient excess capacity to receive
high strength waste feedstock from local food and beverage industries to produce additional
biomethane that can be used for beneficial purposes. The goal of the 13213 project is to use
anaerobic digestion and state -of- the -art RNG production technology to produce CNG to fuel City
vehicles, specifically, the refuse and recycling trucks that service the City. The design work is
currently underway with the 50% design submittal received and under review by City staff. After
extensive research of the capabilities of this developing industry and application of the project
design parameters, only one manufacturer, Unison Solutions, Inc., has been identified that makes
appropriate biogas scrubbing equipment of the capacity and capability needed for this project.
Even though Petaluma is a charter city, and has the power to adopt local regulations governing
City contracts that conflict with state law, the City has not exercised its charter power regarding
City contracts very extensively. As a result, City public works contracts are generally subject to
state public contracting laws, including provisions of the Public Contract Code that limit the
ability of local agencies to specify materials and goods being procured by brand name. Public
Contract Code Section 3400, subdivision (b) prohibits state and local agencies and their officials
from issuing bid specifications for public works projects that limit bids to particular firms or
designate items being acquired by brand name, unless bidders are permitted to propose items
equal to those specified by brand name. However, Section 3400, subdivision (c) includes an
exception that permits designating a material, product or service by brand or trade name in
certain specified circumstances, including when the product is unique and there is no known
competing product. For the exception to apply, the awarding agency or its designee must make a
finding that is described in the bid invitation or request for proposal that a material, product or
service is designated by brand or trade name for one of the reasons permitted under subdivision
(e).
The City's public works contracts and equipment purchases are also subject to the requirements
of the City Charter, which require competitive bidding for acquisitions above $24,600, according
to bidding procedures specified in the purchasing chapter in the Municipal Code. However, ,
similar to the state public works law discussed above, Section 4.04.050 of the Municipal Code
allows dispensing with formal bidding when a commodity can be obtained from only one
vendor. In addition, the common law recognizes a bidding exception for circumstances where
competitive bidding of public contracts otherwise required by statute may be excused, including
circumstances where the contract is such that competitive proposals would be unavailing or
would not produce an advantage, and the advertisement for competitive bid would thus be
undesirable, impractical, or impossible. Government contracts for goods and services only
available from a single source have been held to fall within the exception. Graydon v. Pasadena
Redevelopment Agency (1980) 104 CA3d 631. Because the City intends to purchase the
biomethane scrubbing and processing equipment that will work within the constraints of the 13213
2
Project, and this equipment is available from only one vendor, it is necessary to obtain a sole
source finding prior to completing the request for proposal and negotiating a contract and price
with the vendor.
DISCUSSION
The 13213 project requires a biogas treatment system with the capability to remove contaminants
in the biogas produced at the ECWRF to produce renewable natural gas (RNG). The RNG needs
to comply with Society of Automotive Engineers Standard for CNG Vehicle Fuel — SAE J1616.
Producing RNG from biogas and compressing the RNG for use as vehicle fuel requires relatively
new and innovative methods, which are not widely manufactured. In fact, the innovative gas
treatment system designed and manufactured by Unison Solutions Inc. (Unison) is the only
known biogas treatment system that has a proven track record to successfully produce RNG at
the relatively low biogas flow rates of 100 cubic feet per minute (cfm) or less, needed for the
13213 project. For that reason, the City included Unison Solutions on its project team in its grant
application to the CEC as the vendor to design and furnish the gas treatment system.
Since being awarded the CEC grant, further research has confirmed that the Unison biogas
treatment system is the only proven system that fits the 13213 project design parameters. With this
determination, and given that the CEC grant is anticipating the use of the Unison biogas
treatment system, it is recommended that the City negotiate a sole source contract with Unison to
furnish and install its biogas treatment system. This contract would lock in a negotiated price for
furnishing, installing, and commissioning the equipment. The negotiated contract would then be
presented to City Council for approval prior to award. Added benefits of directly contracting
with the manufacturer include avoiding general contractor mark -ups on the equipment and
reducing risk of project delays, as the equipment has a long lead -time. A similar approach was
recently taken by the City of San Mateo with Unison to provide the same equipment at their
wastewater treatment plant. For these reasons, it is recommended that the Council make the
findings for sole source of the biomethane to CNG processing equipment to Unison.
FINANCIAL IMPACTS
Funds to purchase for the Unison biogas treatment system equipment are budgeted in Capital
Improvement Project number C66501518 for the 13213 project. The CEC grant for the project will
partially cover the costs of this equipment. There is no projected fiscal impact of the
recommended action.

COMPRESSOR SYSTEMS
Using technology from the sour gas industry, Unison
Solutions has developed gas compression systems that resist
the destruction caused by biogas. These systems are used on
turbine, fuel cell, and biogas pipeline projects.
• Skids designed for any gas flow at pressures up to
200 psig
• Two stage condensate removal
• Particulate free delivery with relative humidity less
than 25%
DRYING SYSTEMS
If compression is not required, the same level of gas
conditioning for use with an existing blower or compressor
can be provided. Whether filtration, condensate removal, or
heat transfer is required, we can build a system for the
specific application. Unison Solutions can also provide passive
drying systems for process gases that are not related to
biogas.
BLOWER SYSTEMS
Low pressure blower systems are designed to treat gas for
use in boilers and internal combustion engines such as CAT,
GE Jenbacher, GE Waukesha, Cummins, MWM, Liebherr,
MAN, and Guascor.

HYDROGEN SULFIDE REMOVAL
Hydrogen Sulfide (HZS) and organic sulfur removal from biogas is
often necessary to prevent corrosion, decrease maintenance of
downstream equipment and lower SO), emissions. H2S can also
inhibit the effective removal of siloxanes.
Unison Solutions offers several different sulfur removal
technologies depending on the concentration levels and
application. Technologies range from "scavenger- type" media
based systems to biological systems.
SILOXANE REMOVAL
Nearly all digester and landfill gas contains one or more
species of siloxanes. These are chemicals used extensively in
industrial products such as lubricants and in personal care
products.
When biogas containing siloxanes is combusted in gas
turbines, boilers, fuel cells, or internal combustion engines,
deposits of solid silica (Si02) collect within the equipment.
Damage inflicted by siloxane deposits can be profound,
causing more frequent maintenance and lower generation
capacity.
