SUBJECT: 4.11(c)--A�uthorize Purchase of Biosolids Biodryers for the Clear Creek
Wastewater Treatment Plant
Recommendation
Authorize and approve the following:
(1) Purchase of three Bioforcetech Biodryers and associated equipment for biosolids
processing at the Clear Creek Wastewater Treatment Plant (CCWWTP) in the amount
of$2,599,460;
(2) Authorize an additional $200,000 for taxes and fees associated with the purchase; and
(3) Find the project categorically exempt from review under the California Environmental
Quality Act Guidelines, pursuant to Sections 15301 - Existing Facilities, and 15303 -
New Construction ar Conversion of Small Structures.
Fiscal Impact
The guote for this purchase is $2,599,460, not including associated taxes, duties, and fees.
Funding for the purchase is budgeted and available in the Wastewater Utility Capital
Budget.
Alternatzves Action
The City Council (Council) may choose not to approve this purchase and provide alternate
direction to staff. By doing so, the City will not have the capacity to process all biosolids
through the pyrolysis system and would be in jeopardy of not meeting the regulatory deadline
for organics diversion goals for the State of California by January l, 2025.
Background/Analysis
On December 15, 2020, the City of Redding (City) awarded Request for Proposal (RFP) Bid
Schedule No. 5179 to Waterworks Engineers to provide engineering services to design a
wastewater biosolids pyrolysis system for the CCWWTP.
On August 17, 2021, the City awarded RFP Bid Schedule No. 5211 to Bioforcetech
Corporation to supply Biosolids Drying and Pyrolysis equipment for the Clear Creek
Wastewater Treatment Plan (CCWWTP) as part of Phase I(Pilot Project).
Report to Redding City Council July 12, 2023
Re: 4.11(c)--Authorize Purchase of Biosolids Biodryers for the Clear Creek Wastewater
Treatment Plant Page 2
On August 2, 2022, the City awarded Bid Schedule No. 5293 to SNL Group to construct the
CCWWTP Pyrolysis Project Phase 1, which is currently under construction. This project
consists o�the installation of one pyrolysis reactor and three biodryers to process biosolids
from the CCWWTP. The capacity of this project is not sufficient to handle al1 biosolids
produced at the CCWWTP.
The subject purchase will allow for the completion of the second of the four phases required
to fully complete this project. This second phase wi11 add three additional biodryers and
double the drying capacity, therefore, allowing all of the current biosolids production from
CCWWTP to be processed through the pyrolysis reactor. Additional expansion to this project
(Phases 3 & 4) is planned in upcoming budget cycles to provide additional capacity for the
Stillwater Wastewater Treatment Plant and a11ow for continuous operations when facing
system downtime.
Lead time for delivery of the requested equipment is 12-14 months from approved submittals.
Staff is requesting to purchase and order this equipment to receive and install it prior to
January l, 2025, in order to meet the regulatory deadline for organics diversion goals for the
State of California. The biodryers will be installed with the current construction contract Bid
Schedule No. 5293 under a contract change order.
Environmental Review
Staff has determined that the project is categorically exempt from review under the California
Environmental Quality Act Guidelines, per Sections 15301 - Existing Facilities, and 15303 -
New Construction or Conversion of Small Structures. Class 1 exemptions include the
operation, repair, maintenance, or minor alteration of existing facilities, structures, or
equipment involving negligible or no expansion of use. Class 3 exemptions consist of
construction and location of new small facilities and equipment, or conversion of existing
structures. The City will add new equipment to the existing Pyrolysis system and the project
will result in negligible expansion of use. The project area has been reviewed for sensitive
resources and wi11 not have an effect on biological or cultural resources such as threatened or
endangered species or their habitats, sensitive vegetation communities, tribal lands, or tribal
cultural resources. The project has no potential to have a significant effect on the
environment.
Council Priority/City Manager Goals

COVER LETTER
Dear Josh,
Bioforcetech Corporation would like to thank you for the
opportunity to serve as your biosolids solution and
service provider.
Bioforcetech is in the business of providing biosolids
solutions using two efficient and high value processes,
the BioDryer and the BFT Pyrolysis Unit. While the
equipment can be used independently,the BioDryer and
Pyrolysis units are most effective when configured
together as an integrated system.
BFT BioDryer
The Bioforcetech BioDryer is a unique technology that is
designed to dry biosolids in order to produce a nutrient
rich Class A organic material.The resulting product can
be recycled and applied as a fertilizer or soil amendment.
The BFT-BioDryer can save up to 70°io in energy costs compared to a conventional belt or paddle dryer
since it uses the metabolic energy of bacteria that naturally occur in biosolids, instead of costly fossil
fuels. Each BFT-BioDryer unit is able to dry 8 wet tons of biosolids at 20°io TS in as quick as 60 hours.
The result is Class A biosolids at 75-90°io TS.The BFT-Biodryer is a modular configuration allowing
units to be added to increase capacity and production of rich organic material.
i`.�`�?�,=J"<.i f tC"i"�
BFT Pyrolysis Units
"Pyrolysis" is the thermochemical decomposition of organic material through the
application of heat without the addition of extra oxygen. Through pyrolysis
Bioforectech is able to recuperate value from biosolids,transforming it into
renewable energy and OurCarbon0 biochar. Biochar is a carbon based product that is no longer
considered a biosolid. Biochar produced from the BFT-Pyrolysis has economic value and can be sold
as a fertilizer or as a material that can be used to make sustainable products
(htt s: wvvvv.r��d�vvithcat�rc�rbc�r�.�e�r�).
BFT's pyrolysis systems are self-sustained pyrolysis systems that generate enough energy to maintain
the process,and additional thermal energy that can be recirculated back to the BioDryer for additional
biosolids drying.
A complete Bioforcetech system helps municipal wastewater treatment facilities to meet their
sustainability goals by"producing"a valuable product, rather than costly waste.
The Bioforcetech systems are compact,modular, and self-contained for easy installation and
maintenance,as well as fully automated for 24/7 operation with little to no operator interaction.
We look forward to working with you and your Team on this and future projects. Feel free to contact me
or our local representative for any questions.
Best regards,
Valentino Villa

The BioForceTech (BFT) plant was designed and built to combine a low energy consumption drying
process(mediated by bacterial activity),with a system to add value to biosolids (through a pyrolysis
process), in order to obtain a plant having a positive energy balance.
BFT's ultimate objective was to build a high efficiency plant with low capital cost and limited external
fossil fuel requirements.
Special features were implemented in the design to keep energy waste to a minimum. These include
aeration,waste heat recovery,efficient reactor shape,and insulation methods.
Unlike most biosolids drying systems,which use high energy consumption to achieve high drying
levels,the BFT drying system guarantees a high degree of drying (from 20°io of dry matter to 90°io of dry
matter). This is accomplished by recycling the metabolic waste energy,generated by bacteria already
present in biosolids,as heat.
An energy recovery system (pyrolysis reactor) makes the process sustainable and efficient. Installed
downstream of the dryer,this system minimizes the use of outside energy for the complete treatment
of biosolids from the wastewater treatment plant.

"Upcycling,also known as creative reuse, is the process of transforming by-products, waste
materials, useless, or unwanted products into new materials or products of better quality or for
better environmental value."
At Bioforcetech we embrace this concept and realize it with our sustainable system,converting organic waste
into renewable energy and biochar.
Biochar is charcoal used as a soil amendment. Biochar is a stable solid-rich in carbon,and can endure in soil
for thousands of years. Biochar thus has the potential to help mitigate climate change via carbon
sequestration.

The BFT innovative process is able to dry(i.e.,remove the water from)various types of biomass
without the use of additives,such as fossil fuel energy,chemicals,etc. In a little over 60 hours,the BFT
BioDryer dries organic materials from 20°io solid content to 80°io solid content and above.
Use of the naturally-occurring microbial populations is the essence of our exclusive technology. By
taking advantage of the microbial populations that proliferate inside high-concentration organic
materials,our team has designed an extremely fast bioreactor that promotes life inside the biomass.
As the bacteria grow,they emit heat that BFT uses to remove the water and tap the stored energy.
The bacteria use carbon compounds found in the biosolids to grow and reproduce.The
microorganisms also need oxygen present in the air to complete these reactions.Waste heat is
released during the reactions.
These metabolic reactions alone can significantly increase the temperature inside the reactor in a few
hours. In a system optimized for this purpose such as the BFT BioDryer,this temperature,together with
a correct air flow,are used as the means to carry and evaporate the water held by the material,thus
leading to a high dry solids concentration.
i`.�`�?�,=J"<.i f tC"i"�
Equipment:
The BioDryer is composed of an external structure that is made with painted steel to
prevent rust corrosion and strength loss, and internal parts that are made of AISI
304L and AISI 304 stainless steel.
The AISI 304L is used when a welding process is needed.The stainless steel prevents fast
deterioration.The reactor looks like an octagonal rotating drum and is moved by a motor reducer and
linked to an aeration system. Loading and unloading gates are present on one side of the octagon.
The air system is composed of two blowers,polypropylene (PPH) pipes,and one heat exchanger.The
first centrifugal fan blows the air inside the reactor and provides oxygen for the process. The second
blower sucks the exhaust air and the steam formed during the process.
The PPH guarantees resistance to aggressive chemical agents and also has a good resistance to high
temperatures,up to 230°F.

SUBJECT: 4.11(d)--Award Request for Proposals No. 5179 and Authorize Execution of
Consulting and Professional Services Contract for the Clear Creek Wastewater Treatment Plant
Biosolids Pyrolysis Project
Recommendation
Authorize the following actions relative to Request for Proposals, Bid Sched�ule No. 5179, to
provide engineering services for the Clear Creek Wastewater Treatment Plant Biosolids
Pyrolysis Project:
(1) Award to Water Works Engineers;
(2) Authorize staff to negotiate and the Mayor to execute a consultant services agreement
(Agreement) for project management, environmental permitting and compliance,
geotechnical engineering, surveying, final design and contract documents, and technical
assistance during bidding for the Clear Creek Wastewater Treatment Plant Biosolids
Pyrolysis Project, for a not-to-exceed fee of$749,985; and
(3) Authorize the City Manager to approve contract amendments not to exceed$35,000.
Fiscal Impact
Funding for this project will come from the Wastewater Utility Fund. The City Council
(Council) approved Biosolids Master Plan preliminarily estimates the total small-scale pilot
project cost to be approximately $6.1 million. Sufficient funding for the proposed Water Works
Agreement is included in the 2020-21 Wastewater Utility budget.
Alternative Action
The City Council (Council) may choose not to award the Request for Proposals No. 5179 at this
time and direct staff not to pursue this project. This alternative wi11 delay or eliminate the
construction of the project. Staff would pursue other alternatives to managing biosolids disposal at
the Stillwater and Clear Creek Wastewater Treatment Plants. This may present regulatory, technical
and financial impacts to the Wastewater Utility.
Report to Redding City Council December 10,2020
Re: 4.11(d)--Award RFP No. 5279 Consulting Contract Page 2
Background/Analysis
The City of Redding (City) owns and operates two municipal wastewater treatment plants
(WWTPs). The C1ear Creek plant (CCWWTP) generally serves the west side of Redding with a
tributary area population of approximately 74,000 people. The Stillwater plant (SWWTP)
generally serves the east side of Redding with a tributary area population of approximately
24,000 people. Both plants discharge directly treated water to the Sacramento River.
Prior to 2014, the City disposed of WWTP biosolids through a combination of land application at
the Redding Airport and landfilling. However, the land application site is nearing its lifetime
capacity to accept additional biosolids due to metals loading, and the City has now been
exclusively disposing of biosolids at the West Central LandfilL This change also coincided with
a transition at CCWWTP from the use of drying beds to mechanical dewatering with a centrifuge
facility.
Recent State legislative changes regarding greenhouse gas emissions and the disposal of organic
waste (California Senate Bill (SB) 1383, California Assembly Bill (AB) 1826, AB 876, AB 341,
and AB 1594) may result in the landfill no longer accepting biosolids within the coming years.
SB 1383 codified California's commitments to red�uce greenhouse gas emissions and air pollution
statewide. It identified methane emissions from landfills as one area to address in order to meet
California's target to reduce Greenhouse Gas (GHG) emissions 40 percent below 1990 levels by
2030. SB 1383 enhances California's efforts to achieve the statewide 75 percent recycling goal
by 2020, established in AB 341, and strengthen the implementation of mandatory commercial
organics recycling established in AB 1826. As AB 341 set the roadmap to find beneficial uses
for organics and divert them from landfills, AB 1594 specifically phases the credit allowed from
biosolids being utilized as "Alternative Daily Cover" and classifies all green waste as regular
disposal. What this means is that landfills are being told to divert organic waste from landfills
including biosolids, therefor landfill disposal of biosolids wi11 not be a viable option in the
future.
In 2019, staff updated the Wastewater Biosolids Masterplan, including an alternative analysis of
different technologies to effectively dispose of biosolids. Pyrolysis was selected as the preferred
alternative for implementation. This process uses thermal decomposition of organic material
through the application of heat without the addition of extra air or oxygen converting the organic
material into two byproducts, syngas and biochar. The process is self-sustaining, as syngas is
created and combusted in a flameless reactor, creating the heat source to produce even more
syngas and process the organics into biochar. Biochar is the seguestered carbon portion of the
organics that remains after the pyrolysis process is complete and is similar to a commercial
activated carbon. Biochar has been used worldwide as a soil amendment, a replacement for
carbon black in plastics manufacturing, carbon electrodes in super-capacitors for energy storage,
food packaging, waste water treatment, air filtration, livestock feed supplement, for water
filtration, and as a composting agent.
On October 6, 2020, the Council authorized staff to solicit engin�ering services for the pyrolysis
project. At the end of October 2020, staff advertised Request for Proposals No. 5179, to select an
engineering firm to provide project management, design services, environmental permitting and
technical services to facilitate the design and construction of a pilot scale biosolids pyrolysis
system with plans for expansion to accommodate full-scale operation. The new pyrolysis process
will help the wastewater utility meet future and existing regulatory requirements.
Report to Redding City Council December 10,2020
Re: 4.11(d)--Award RFP No. 5279 Consulting Contract Page 3
Two proposals were received on November 20, 2020, from Water Works Engineers and GHD,
Consultants, both of Redding. Copies were distributed to the selection panel made up of Public
Works and Treatment P1ant staff and evaluated on the following factors — understanding of the
scope of work, ability to meet the proposed schedule and maintain the project budget, experience
and qualifications of the proposed staff, project approach, familiarity with City projects,
requirements and standards, and geographic location of the teain. Applying these criteria to the
proposals, the selection panel determined that Water Works Engineers is the best candidate to
provide the required services for this project.
If authorized, staff will negotiate a final cost based on the scope of required services with Water
Works Engineers. The consultant fee is estimated and the agreement wi11 be for actual work
performed. Due to the complex nature of the project, staff recommends the approval of an
additional $35,000 in contingency reserve for the contract. If this reserve needs to be utilized, a
contract amendment would need to be negotiated with the consultant and executed with approval
of the City Manager.
This project wi11 be a first-phase implementation allowing for testing of the pyrolysis technology,
while allowing the City to process a significant amount of biosolids produced at the Clear Creek
WWTP. Staff will gain first-hand experience of the performance and operational requirements of
the pyrolysis system. Staff anticipates utilizing the pilot facility to allow for testing the
processing of some biosolids produced at Stillwater WWTP, as that plant operates a completely
different biosolids management process. Plans for full-scale implementation of the technology
will be expected to process all biosolids produced by both facilities, ensuring that the City is
achieving the required significant diversion of organic waste from landfill disposal.

SUBJECT: 4.11(h)--Authorize a Pilot Scale Project for Biosolids Pyrolysis Process.
Recommendation
Authorize staff to solicit engineering services to design and construct a small-scale pyrolysis
system to process municipal wastewater biosolids (biosolids) at the Clear Creek Wastewater
Treatment Plant.
Fiscal Impact
The City Council (Council) approved Biosolids Master Plan preliminarily estimates a small-scale
pyrolysis project will cost approximately $6,100,000. Moving forward with the design phase is
estimated at $610,000. Sufficient funding is available in the current Fiscal Year 2020-21
Wastewater Utility budget.
AlteNnatives Action
The Council may decline to approve this project and provide alternate direction to staff. Staff
would pursue other alternatives to managing biosolids disposal at the Stillwater and Clear Creek
Wastewater Treatment Plants. This may present regulatory, technical and financial impacts to
the Wastewater Utility.
Background/Analysis
Staff is proposing to engage a consultant to assist with planning and design of a small-scale
pyrolysis unit to better prepare the City of Redding (City) to comply with environmental
regulations and provide a long-term sustainable solution to the disposal of biosolids from both
wastewater treatment plants. The handling and disposal of biosolids is highly regulated, with
eontinuously evolving environmental legislation in the State of California. The City of Redding
(City) currently disposes of this material at the local]andfills.
Report to Redding City Council September29,2020
Re: 4.11(h)--Authorize Biosolids Pyrolysis Project at CCWWTP Page 2
California Senate Bill (SB) 1383 codified California's commitments to reduce greenhouse gas
emissions and air pollution statewide. It identified methane emissions from landfills as one area
to address in order to meet California's target to reduce Green House Gas emissions 40 percent
below 1990 levels by 2030. SB 1383 enhances California's efforts to achieve the statewide 75
percent recycling goal by 2020, established in California Assembly Bill (AB) 341, and
strengthen the implementation of mandatory commercial organics recycling established in AB
1826. As AB 341 set the roadmap to find beneficial uses for organics and divert them from
landfills, AB 1594 specifically phases out the credit allowed from biosolids being utilized as
"Alternative Dai1y Cover" for landfills and classifies all green waste as regular disposal. What
this means is landfills are being forced to divert organic waste, including biosolids, whereas
landfill disposal of biosolids wi11 not be a viable option in the future.
More recently, the State Water Resources Control Board (SWRCB) issued an order requiring all
Publicly Owned Treatment Works (POTWs) to sample and report results for Per- and
Polyfluoroalkyl Substances (PFAS). PFAS are a group of man-made chemicals that have been in
use since the 1940s and are found in a wide range of consum�r products used daily such as
cookware, pizza boxes and stain repellants. These chemicals are commonly conveyed via the
wastewater to the POTW passing through the plant tr�atment proc�sses and remaining in �he
biosolids as they are not removed from the effluent waste stream. The Wastewater Utility wi11
begin sampling for PFAS at its wastewater treatment plants shortly and will know if PFAS are
present by early next year.
On August 18, 2020, the Council accepted the aforementioned 2020 Biosolids Master Plan as a
general planning document to be used by the Wastewater Utility. Several biosolid disposal
alternatives were eval�uated utilizing many technical, financial and regulatory criteria. The
recommended alternative was implementation of new technology utilizing process known as
pyrolysis.
Pyrolysis is the process of burning withou� a flame; utilizing heat produced to thermally remove
volatils organics, leaving behind a sequestered carbon solid that is held in a permanent state that
can be beneficially reused. This "biochar" locks the carbon into an extremely stable and
bene�cial soil amendment that returns the carbon to the soil, therefore virtually eliminating the
releasing of carbon in the form of inethane to the atmosphere. Other uses for the residual biochar
include a replacement for carbon black in manufacturing and as activated carbon for filtration.
The potential benefits of pyrolysis include the following:
l. A red�uction of biosolids in volume and weight by up to 90 percent, could be achieved,
thus substantially reducing storage and hauling costs.
2. A high percentage of the carbon content of the material processed is retained in pyrolysis
biochar, resulting in less overall carbon dioxide emissions (i.e. sequestration).
3. Biochar has the potential to be used as a soil amendment or replacement for carbon black
in an industrial manufacturing process.
4. Since pyrolysis does not fully combust the material being processed, compliance with air
quality requirements for the system exhaust is more readily achievable and permitting
will be less complex.
5. Pyrolysis of biosolids results in the destruction of PFAS, which are an emerging
coneerning contaminant that could affect land application of biosolids in the future.
Report to Redding City Council September29,2020
Re: 4.11(h)--Authorize Biosolids Pyrolysis Project at CCWWTP Page 3
6. Pyrolysis is largely unaffected by the nitrogen content of the biosolids being processed,
which makes this technology particularly attractive when taking into consideration the
acceptance of food waste.
7. Pyrolysis can be a self-sustained process that generates enough energy such that
electricity or natural gas are not used once stable operation is achieved, once the
pyrolysis process operating temperature is reached (using syngas generated from the
biosolids to burn).
The Biosolids Master Plan recommended that the City consider implementing a small-scale
pyrolysis system at Clear Creek Wastewater Treatment Plant (CCWTP) in order to gain
operating experience to prove the technology prior to constructing a full-scale facility. As of
today, pyrolysis is an emerging technology and selection of this alternative may result in the
need to sole-source or pre-select an equipinent provider with a track record of proven municipal
installations, given there are very few in the United States. Operation of a small-scale facility
could be an important step in meeting regulatory goals and establishing a permanent solution for
the disposal of biosolids.
Staff will continue to investigate alternative disposal methods including trucking to regional
facilities, composting, and land application to ensure flexibility in decision making and ultimate
investment of resources.

Recommendation
Accept the Wastewater Treatment P1ant Biosolids Masterplan as prepared in consultation with
Waterworks Engineers.
Fiscal Impact
There are no direct fiscal impacts from accepting this planning document. The consultant costs to
prepare the Biosolids Master Plan totaled $112,157.
Alternative Action
The City Couneil may choose not to accept the Biosolids Master Plan. Staff will continue to
study and evaluate alternatives to comply with local, State, and Federal law while processing
municipal biosolids.
BackgNound/Analysis
The City of Redding (City) owns and operates two municipal wastewater treatment plants
(WWTPs). The Clear Creek plant (CCWWTP) generally serves West Redding with a tributary
area population of approximately 74,000 people. The Stillwater plant (SWWTP) generally serves
East Redding with a tributary area population of approximately 24,000 people. Both plants
discharge directly to the Sacramento River following treatment.
A byproduct of wastewater treatment is the accumulation of organic waste known as biosolids.
Prior to 2014, the City disposed of WWTP biosolids through a combination of land application at
the Redding Airport and hauling to the landfill. However, the land application site is nearing its
lifetime capacity to accept additional biosolids due to metals loading, and the City has now been
exclusively disposing of biosolids at the West Central LandfiIl. This change also coincided with
a �ransition at CCWWTP from the process of using dryi.ng beds to using mechanical dewatering
with a new facility.

Re: 4.11(e)--Biosolids Masterplan Page 2
Recent State of California legislative changes regarding greenhouse gas emissions and the
disposal of organic waste (California Senate Bill (SB) 1383, California Assembly Bill (AB)
1826, AB 876, AB 341, and AB 1594) may result in the landfill no longer accepting biosolids
within the coming years. SB 1383 codified California's commitments to reduce greenhouse gas
(GHG) emissions and air pollution statewide. It identified methane emissions from landfills as

below 1990 levels by 2030. SB 1383 enhances California's efforts to achieve the statewide 75
percent recycling goal by 2020, established in AB 341 and strengthen the implementation
of mandatory commercial organics recycling established in AB 1826. As AB 341 set the
roadmap to fmd beneficial uses for organics and divert them from landfills, AB 1594 specifically
phases the credit allowed from biosolids being utilized as "Alternative Daily Cover" and
classifies all green waste as regular disposal. Consequently, landfills will be required to divert
organic waste, which includes biosolids, from the landfill, and therefore will no longer be a
viable option for disposal in the future.
City staff engaged Waterworks Engineers to develop an update to the City's Biosolids Master
Plan (Plan). The purpose of the Plan is to evaluate the biosolids disposal options available to the
City in terms of capital costs, operating costs, and other non-cost considerations to determine the
preferred disposal method that will be pursued in the future. Five different alternatives were
studied including various forms of land application in other areas, incineration, a thermal
hydrolysis process, and a high temperature thermal process known as pyrolysis. The various
alternatives were researched and ranked according to their impact on the following criteria:
� Cost, both capital and operational
• Long term reliability
• Public perception
� Operational staffburden
� Complexity of the regulatory permitting requirements
Based on the analysis, the pyrolysis alternative yielded the lowest net present value for the City.
Key benefits of this disposal option include the lowest overall cost, an automated conveyance
systeln that is less labor intensive than other alternatives, the ability to eliininate any emerging
containinant, and elimination of the need to purchase and maintain a land application site. The
pyrolysis technology is a new emerging process and will need to be vetted prior to any
significant investment to ensure long term scalability and reliability.
City staff may pursue multiple disposal options moving forward to ensure maximum flexibility
and minimize risk that comes with reliance on a particular disposal method.

Report to Redding City Council August 10,2021
Re: 4.11(d)--Award RFP No 5211 Page 2
Background/Analysis
At its meeting on August 18, 2020, the Council accepted the Wastewater Treatment Plant
Biosolids Master Plan (Plan). The Plan recommended an emerging technology for the handling
and disposal of Biosolids known as Pyrolysis. In response, the Council awarded a consulting and
professional services agreement in October 2020 with Water Works Engineers (WWE) to begin
the preliminary design process for the Clear Creek Waste Water Treatment Plant (CCWWTP)
Biosolids Drying and Pyrolysis pilot project. As part of the preliminary design process, a
Request for Proposals (RFP) was developed to solicit multiple manufacturers of the pyrolysis
equipment to provide an equivalent element evaluation of their ability to provide the required
process for both pilot scale and ultimate build out systems.
Five proposals were received on July 1, 2021; however, two of the proposals were deemed non-
responsive for failure to meet required elements in the solicitation. The remaining three
proposals received included Chartech Solutions, Anaergia, and Bioforcetech Corporation. The
proposals were reviewed by the selection panel made up of Public Works and Treatment Plant
staff, as well as WWE, and evaluated on the following factors: manufacturer's experience,
proposed system operational complexity, system capacity, required ancillary systems and
utilities, maintenance requirements and availability of spare parts and service, Biochar
management plan, submittal and equipment delivery schedule, exceptions taken to the advertised
RFP, and system cost (capital, operation and maintenance). Applying these criteria to the
proposals, the selection panel determined that Bioforcetech Corporation is the best candidate to
provide the required services and equipment for this project.
Once the manufacturer of the equipment has been approved, staff will execute a purchase order
and work with WWE to complete �nal design of the facility for advertisement construction bids.
It is anticipated that construction will begin in late 2022 with an estimated completion date and
facility start-up in 2023.

Re: 4.11(a)--Award Bid Schedule No. 5293 CCWINTP Pyrolysis Phase 1 Project Page 2
Project cost components are estimates and some shifting of the project development and
construction contingency funds may be necessary to balance the project within the approved
budget.
Alter�native Action
The City Council may choose to not award the bid for the Clear Creek Wastewater Treatment
Plant Pyrolysis Phase 1 Project and provide staff with alternative direction. Without this project,
staff would need to pursue other alternatives to managing biosolids disposal at the treatment
plant. This may present regulatory, technical, and financial impacts to the Wastewater Utility in
the near future.
Background/Analysis
The Clear Creek Wastewater Treatment Pyrolysis Phase 1 Project is an accepted project from the
Wastewater Treatment Plant Biosolids Master Plan. The City Council authorized staff to solicit
engineering services to design and construct the pilot scale project on October 6, 2020. The
project is using an emerging technology for the handling and disposal of biosolids at the
wastewater treatment plant. The following items are included in the scope of this project:
installation of biodryers and pyrolysis units, installation of conveyors and elevated support
structure with walkway for access and utility routing, installation of a transformer and electrical
building, construction of concrete slabs, installation of a pre-engineered metal canopy, and site
work which includes yard piping, grading,paving, fencing, and electrical facilities.
Attached is a tabulation of bids received and opened on July 19, 2022, for the Clear Creek
Wastewater Treatment Plant Pyrolysis Phase 1 Project. The low bid in the amount of$3,927,250
was received from SNL Group, Inc., of Redding, California. The engineer's estimate was
$3,894,000. Total project development costs for this project are estimated to be $845,000.
Project development costs include engineering, surveying, right-of-way, environmental, and
consultant services. Total construction administration and inspection costs for this project are
estimated to be $795,000. Construction administration and inspection costs include staff time and
the consultant fee received through RFP selection. The consultant's fee includes contract
administration, inspection services, and application programming, which is unique to this
project. Staff will offer to the Council approval of the consultant selection and execution of the
professional services agreement at a later meeting prior to the beginning of construction.
Staff has reviewed the project and determined that the project is Categorically Exempt from
review under the California Environmental Quality Act (CEQA) Guidelines, per Section
15301(b) - Existing Facilities and Section 15303 (d) New Construction or Conversion of Sma11
Structures. Class 1 exemptions include minor alteration of existing public facilities and
equipment. Class 3 exemptions include the construction of new small facilities or structures, and
installation of new equipment. The project will result in negligible or no expansion of use, and a
limited amount of new equipment and structures will be constructed. The project has been
reviewed for sensitive resources and will not have a significant effeet on biological or cultural
resources such as th.reatened or endangered species or their habitats, sensitive vegetation
communities, tribal lands, or tribal cultural resources. The project has no potential to have a
significant effect on the environment.
