BACKGROUND
The Emergency Sludge Loadout Facility(ESLF) is located within the wastewater treatment plant in
Martinez and is used for emergency storage and truck loading of dewatered raw sludge (sludge) in case
the incinerators are unavailable. Since the commissioning of the ESLF in 2010, the facility has been rarely
used or tested. This is due to the significant deficiencies related to the existing conveyance and odor
control systems. These systems do not allow operators to control the flow of sludge from the silos into the
conveyor and then into hauling trucks without overflowing, and thus spraying sludge on equipment, trucks,
and personnel. Sludge releases extremely odorous air, and the amount of sludge contained within the
ESLF renders the existing odor control system inadequate. The ESLF Upgrades, District Project(DP)
7348A(ESLF Project)will install new isolation and modulating gates on the sludge silos, make mechanical
and controls system improvements, upgrade the odor control with a new system, and upgrade the
ventilation to allow a safer and fully functional system to operate. The work under this project will increase
operational reliability and flexibility for emergency solids handling.A map showing the location of the ESLF
Project is included as Attachment 1.
The ESLF Project is the first of three construction contracts as part of the Solids Handling Facility
Improvements, DP 7348 (Solids Project). These three separate contracts include the ESLF Project, the
Sludge Blending Tank Repairs, DP 6172, and the Solids Project. The Sludge Blending Tank Repairs
Project and ESLF Project are being constructed ahead of the Solids Project to ensure that the sludge
bending tank and ESLF is fully functional and available for use during construction of the Solids Project,
which is scheduled to be awarded by mid-2020.
The Engineer's estimate for construction of the ESLF Project was $2,300,000. This project was
advertised on April 26 and May 1, 2019. Three sealed bids were received and publicly opened on May 30,
2019. The Capital Projects Division conducted a technical and commercial review of the bids and
determined that Auburn Constructors, LLC is the lowest responsive and responsible bidder with a total bid
amount of$2,150,300.A summary of bids received is shown in Attachment 2.
Black& Veatch Corporation (B&V) designed the ESLF Project as part of the larger Solids Project. Staff
recommends amending the existing professional engineering services agreement with B&V to
include engineering services during the construction phase. The additional engineering services will
include submittal review, design response services, field verification, and asset management record
support.A$220,000 cost ceiling has been negotiated with B&V to provide these services, which includes
a cost of$45,000 to update the record drawings and asset information for the entire facility. The asset and
drawing documents will be incorporated in Cityworks and GeoPortal (database systems for staff).
Central San staff will administer the construction contract and provide contract management and
administration. Construction inspection will be done by one of Central San's existing consultant inspection
agreements. In addition, staff will be coordinating and managing the solids disposal under a separate
contract with Lystek International Inc. (Lystek), as a pilot effort during the commission of the ESLF
Project. Lystek is an organic materials and recovery firm with experience working with wastewater
municipalities for solids waste management in an environmentally safe manner and located at the Fairfield
Suisun Sewer District.
CEQA
Staff has concluded that this project is exempt from CEQA under Central San's CEQA Guidelines
Section 15301, since it involves minor alterations to existing public facilities involving no expansion of use,
and CEQA Guidelines Section 15302, since it involves replacement of existing public facilities at the
same location and with the same purpose.Approval of this project will establish the Board's independent
finding that this project is exempt from CEQA.

ALTERNATIVES/CONSIDERATIONS
The Solids Project is a two to three year construction effort and highly complex. Several critical equipment
and processes will be offline and coordinated for the construction of replacement systems including, but
not limited to, the incinerator controls, air pollution control equipment, dewatering equipment, and new
electrical and controls infrastructure in the Solids Conditioning Building. Staff recommends upgrading the
ESLF before commencing the Solids Project to provide a loading system that can be used more on a
daily basis in case of issues that could arise during the Solids Project.
The Board may elect to reject all bids and provide another alternative.
FINANCIAL IMPACTS
The total estimated costs for constructing this project is $3,548,000, which includes planning, design,
construction contract, contingency, and construction management costs as shown in Attachment 3.
The ESLF Project is being funded by the Solids Project under a sub-account, which has adequate budget
for the ESLF Project construction phase. No transfer of funds will be required. The Solids Project is listed
under the Fiscal Year(FY) 2019-20 Budget on page 182 with a FY 2019-20 project budget of$6,550,000.
COMMITTEE RECOMMENDATION
The Engineering and Operations Committee reviewed this matter at the June 4, 2019 meeting
and recommended approval of the project. The Committee suggested to update the Board on the Lystek
pilot, especially if it is successful.
RECOMMENDED BOARD ACTION
Staff recommends the following:
1. Find that the Project is exempt from CEQA;
2. Award a construction contract in the amount of$2,150,300 for the construction of the Emergency
Sludge Loadout Facility Upgrades, District Project 7348A, to Auburn Constructors, LLC, the lowest
responsive bidder;
3. Authorize the General Manager to amend the existing professional engineering services
agreement with Black& Veatch Corporation to include construction services in the amount of
$220,000; and
4.Authorize the General Manager to execute the Contract Documents subject to submittal
requirements and include up to a 15-percent contingency.
