ISSUE: On July 23, 1984, sealed bids for District Project No. 3836,
Remodel Office Building at 1250 Springbrook Road, Walnut Creek,
California, were received and opened. The Board of Directors must award
the contract or reject bids within forty-five (45) days of the public
opening.
BACKGROUND: During January, 1983, District's general offices were
relocated from the Springbrook Road office building in Walnut Creek to
5019 Imhoff Place, Martinez, California. District's Collection System
Operations Department (CSO) remained at the Springbrook Road location.
After considerable evaluation it was decided to remodel the lower portion
of the Springbrook Road Building for use of the CSO Department and
eventually lease the upper portion of the Springbrook Road Building.
When this issue was discussed with the Board in November, 1983, the
construction cost of the remodeling work, not including design and
incidentals, was estimated to be $200,000. $25,000 was authorized for
design work by an architect, District force account expenses, and lease
preparation. The architectual firm of Perry Haviland Associates,
Oakland, California, was selected to prepare plans and technical
specifications for the remodeling work necessary to accommodate the CSO
Department.
Upon completion of the plans and technical specifications by Haviland and
review by the District, the Notice to Contractors inviting bids was
published on June 18, 1984. Proposals were opened on July 23. A
tabulation of all bids received appears on Attachment A. The architect's
estimate for the work is $220,000. Seville Investment Corporation
submitted a bid which was nonresponsive because a bid bond was not
included and there was a discrepancy in the lump sum bid amount. The bid
by Seville should be rejected by the Board of Directors as being
nonresponsive.
The apparent lowest bidder is Malpass Construction of Pleasant Hill at a
lump sum amount of $215,000. The apparent low bid has been reviewed and
has been determined to be responsive. Malpass' references have been
checked, and Malpass has been determined to be a responsible contractor.

A summary of the funds required for the project is shown on Attachment B,
the "Post Bid-Preconstruction Estimate of Costs" for District Project No.
3836. Funds are included for the construction costs, construction
management, moving expenses, and relocation of utilities. The total
additional funds estimated to be required to complete Project No. 3836 is
$268,476. This project is included in the District's five-year Capital
Expense Plan.
In the near future, the existing roof on the Springbrook office building
will be replaced under separate contract. The cost of the replacement is
estimated to be between $25,000 and $35,000.
RECOMMENDATION: Authorize award of the contract for construction of
District Project No. 3836 to Malpass Construction in the amount of
$215,000 and authorize $268,476 in sewer construction funds for project
completion. Reject the nonresponsive bid by Seville Investment
Corporation.

AUTHORIZE $208,000 FROM THE SEWER CONSTRUCTION FUND FOR
GRANT ADMINISTRATION ON THE STAGE 5A AND 5B PROJECTS
TYPE OF ACTION
AUTHORIZE FUNDS
SUBMITTED BY
Curtis Swanson Senior Engineer
INITIATING DEPT./DIV.
Planning Division
ISSUE: Additional funds are required to enable District staff to
continue grant administration efforts on the Stage 5A and 5B Projects.
BACKGROUND: Funding for grant administration efforts associated with the
Stage 5A and 5B Projects has been requested on an annual basis. The
District has seven grants for the Stage 5A Phase I, Phase II; 5B Phase I,
Phase II Projects. The total amount of the seven grants is approximately
$72.9 Million.
The Engineering Department plans to increase its effort on grant
administration during the next year to prepare for federal audits of the
Stage 5A Phase I and II Projects and for construction of the Stage 5B
Project. The increased effort is due to the outcome of audits of other
sanitation agencies' projects that are similar to the Stage 5A and 5B
Projects. These agencies have had substantial portions of project costs
disallowed by auditors for various reasons. Recovering these costs
involves a costly and time consuming appeal process. Staff hopes to avoid
the appeal process by anticipating and addressing potential problems before
the audit.
A summary of the work planned for the major grants is as follows:
Stage5A Phase I
The Engineering Department will continue to lend support towards the
termination and close-out of this grant. Audit preparation involving
force account and consultant costs will be performed. Reconciliation of
previous grant progress payments is nearing completion which will lead
to a payment request up to the 95% limit of the grant. Before
termination of this grant, staff will attempt to obtain funding for the
seismic structural improvements and cathodic protection system elements
of the Stage 5A Completion Project. A pre-audit review of the Stage
5A-I grant is planned for January 1985. Funds for this review which
will be performed by a consultant will be requested at a later date.

RAB
Stage- 5 A Pha-se- H
This project has been completed but has not yet been audited. A
pre-audit review has just been completed and staff will be implementing
the recommendations of this review to mitigate potential audit problems.
One of the recommendations of the pre-audit review is that the District
prepare an indirect cost rate proposal as part of the District force
account costs claimed for this project. Staff intends to retain a
consul tant to prepare part of the indirect cost proposal. Funds for
this consultant will be requested at a later date.
Stage 5B- Phase-I
The District recently received grants for construction of the Stage 5B
Project. Staff will implement changes to the current grant
administration system before construction begins to minimize audit ~
preparation efforts at the end of the project.
St~ge --5B Pha~ - II
Over $1.2 Million was expended for solid waste resource recovery pilot
studies, the biological phosphorus removal pilot study, and other
planning studies under this grant. Efforts will be made to prepare
this project for audit and close-out.
Funding of $208,000 is required for grant administration activities
during the next year. This amount includes a District overhead
allowance and employee fringe benefits. The requested level of funding
represents 2-1/2 man-years of effort and constitutes approximately 70
percent of the total effort to prepare the grants for audit and
close-out. A summary of the funds requested is attached.
District staff will be assisted with the planned activities by Mr. Tom
Kawaguchi. Mr. Kawaguchi is a financial management consultant with
extensive experience with federal grant programs including the audit
process. The estimated cost for these services is $37,340 and is
included in the $208,000 authorization requested.

AUTHORIZE $1,500,000 FROM SEWER CONSTRUCTION FUNDS TO
COMPLETE THE INCINERATOR REPAIR AND MODIFICATIONS PROJECT
TYPE OF ACTION
AUTHORIZE FUNDS
SUBMITTED BY
Steve McDonald, Project Manager
INITIATING DEPT./DIV.
Engineering Division
ISSUE: Funds must be authorized to complete repairs and modifications
required to make the incinerator system operational.
BACKGROUND: Beginning on September 30, 1982, the District Board of Directors
authorized an initial $1.9 Million towards an estimated $4.6 Million effort to
complete the existing incinerator facility. The initial authorization provided
funding for the correction of known problems and for a two-month test to
identify the suitability of the incinerators for long-term operation.
The efforts of an integrated project team composed of District forces,
contractors, and outside consultants culminated 12 months later in the
successful start-up, operation, and test of the incinerator system. This was a
very complex undertaking which met all start-up and test goals.
The testing identified additional work in the process, equipment, and control
areas which needed to be completed to assure reliable long-term incinerator
operation. The project team developed a priority list, schedule, and budget to
identify, design, and implement solutions. The Board approved two subsequent
authorizations bringing the project budget to $3.1 Million.
A summary of major project accomplishments is:
o All original mechanical and electrical equipment has been tested and repaired
or modified as required.
o Some of the required additional mechanical and electrical equipment has been
installed.
o Air pollution District permits have been issued for both incinerators.
o Ash from the incinerator operation has been classified as a non-hazardous
waste by the California Department of Health Services.
o District personnel have been trained and are competent at incinerator
operation and maintenance.
o All major process, equipment, and control problems have been identified.

o District project management has kept the project on schedule and on budget.
As of July 15, 1984, the project budget was 97% expended. Start-up for
long-term operation is targeted for October 1984.
At this time the authorization to complete the incinerator repair and
modification project can be accurately determined. The authorization required
is $1,500,000 bringing the total project authorization to $4,606,400. A detailed
breakdown of the costs is included in the attachment to this position paper. A
brief summary of the major cost elements follows.
Incinerator System Control Room
Controls and instruments for the incinerator system are scattered throughout the
four floors of the solids conditioning building. When the incinerators are in
operation, the environment will consist of high temperatures and high noise
levels. The control room will provide a centralized instrumentation and control
package including an integrated graphical alarm panel in a controlled
environment. This facility is required for effective and efficient incinerator
operation.
Fuel Gas System Modification
The incinerators can be operated using less expensive landfill gas; however,
there will be times when the demand for landfill will exceed the supply. The
existing facilities do not provide the ability to supplement landfill gas with
natural gas during high demand periods, and in the event of a failure in the
landfill gas supply, air pollutant emissions would occur. The fuel gas system
modifications would provide the hardware necessary to supplement landfill gas
with natural gas and in the event of an interruption in the landfill gas supply,
to automatically transfer to natural gas without causing excessive air pollutant
emissions.
Emergency Power Provisions
The plant experiences occasional unplanned electrical power interruptions.
Certain critical and expensive parts of the incinerator would be damaged by high
temperatures that would result from loss of cooling air during a power failure.
The addition of an engine-driven generator would provide uninterrupted operation
of the incinerator cooling air fans.

INITIATING DEPT./DIV.
GEN. MGR./CHIEF ENG.
Process Modifications
Modifications to seven incinerator subsystems are required to provide stable and
reliable incinerator operation. The modifications range from providing a boiler
feedwater system with adequate capacity to meet all operatinp; conditions to
installing adequate seats in the natural draft dampers.
Upon completion of the work included in this authorization, the incinerators
will be fully operational; however, there are two possible future activities
associated with the Incinerator Repair and Modifications Project that are not
included in this final authorization. They are 1) the waste heat recovery
boiler bypass and 2) the incinerator process optimization project. Work on both
of these activities must await the results of our long-term operating
experience. The waste heat recovery boiler bypass has been deferred because of
its hip;h cost (approximately $600,000) and lack of operational experience. Based
on the operational experience to date, it does not appear that a bypass will be
required. The process optimization project is intended to reduce the cost of
incinerator operation. Treatment plant process modifications that will occur as
the result of the Stage 5B Project, will have a significant impact on the
character and quantity of sludp;e produced. The optimization project will be
undertaken in 1986.
The Incinerator Repair and Modification Project is included in the 5-Year
Capital Expenditure Plan.
RECOMMENDATION: Authorize $1,500,000 from Sewer Construction Funds to complete
the incinerator repairs and modifications project.

AUTHORIZE $20,000 FROM THE SEWER CONSTRUCTION FUND FOR
UNDERTAKING A WATER RECLAMATION STUDY
AUTHORIZE FUNDS
SUBMITTED BY
Curtis Swanson, Senior En~ineer
INITIATING DEPT./DIV.
Planning Division
ISSUE: Funds are needed to initiate a water reclamation study.
BACKGROUND: The Sta~e 5A Project was originally planned and designed as a
water reclamation facility, because of a State Water Resources Control Board
(SWRCB) requirement to implement reclamation. Although reclamation facilities
were constructed, a relaxation of waste discharge requirements, in addition to
numerous treatment plant defects, made reclamation impractical as originally
envisioned.
During the past several months, the District has been negotiating a
termination a~reement for the Sta~e 5A Grant with EPA and SWRCB. One of the
conditions of this a~reement will likely be that the District study and
promote the cost-effective use of reclaimed water and, if possible, make use
of the reclamation facilities funded under the Stage 5A Grant.
In a related matter, the District has proposed to Contra Costa Water District
(CCWD) that a joint project be undertaken to study water reclamation within
each a~ency's service area as a step toward resolvin~ problems with the 1972
Reclaimed Water Supply Agreement between CCWD and the District.
Plannin~ Division staff will begin planning for a water reclamation study that
will satisfy both the grant termination condition and the requirements for a
joint project with CCWD. Planning for the study includes defining the scope
of the study, reviewin~ past local and regional reclamation studies, making
contact with State water officials and potential users, defining water quality
criteria by type of use, preliminary identification of potential markets for
reclaimed water, and investi~atin~ possible funding sources for a reclamation
study and a possible reclamation project.
An authorization of $20,000 is requested to cover staff and other costs during
the study planning phase of the reclamation project.
RECOMMENDATION: Authorize $20,000 from the Sewer Construction Fund for
undertaking a water reclamation study.
