1. Call Meeting to Order
Chair McGill called the meeting to order at 4:15 p.m.
2. Public Comments
None.
3. Review Construction Progress for Collection System Operations Department (CSOD)
Administration, Crew and Warehouse Facility, District Project 8208
Senior Engineer Alex Rozul described the scheduling software and approach being
used by the project’s contractor. He referenced the construction schedule posted on
the wall in the construction trailer. He also noted that the District has an outside
party, Swinerton and Walberg, providing a monthly analysis of the contractor’s
schedule to assist staff in identifying areas of concern. Chair McGill noted that the
linear nature of the contractor’s schedule may provide opportunities for concurrent
activities and schedule reduction. Mr. Rozul concurred with his assessment. Chair
McGill further noted that he is less concerned with the schedule than with the proper
construction of the project. Member Menesini concurred that given CSO is operating
well from the Martinez site, there is no reason to overemphasize the schedule at the
expense of ensuring the project is well built.
COMMITTEE ACTION: Reviewed the construction progress.

*4. Review Progress on Other Critical Construction Projects
Senior Engineer Ba Than presented the latest construction photos (attached) and
updated the Committee on the following four projects: Solids Handling Improvements,
Dry/Wet Weather Bypass Improvements, Standby Power Facility Improvements and
Treatment Plant Piping Renovations.
COMMITTEE ACTION: Reviewed the progress of the projects.
*5. Report on the following:
National Nutrient Issues and Strategies from National Association of Clean Water
Agencies (NACWA) Nutrient Summit in Chicago on September 16-17, 2010
Emission guidelines for existing sewage sludge incinerators (Section 129 of the
Clean Air Act)
Other regulatory issues being considered for development of Ten Year Capital
Improvement Plan
Director of Engineering Ann Farrell and Associate Engineer Gail Chesler presented
updates to the Committee (attached) on pending regulatory initiatives that could add
significant costs to the Ten-Year Capital Plan compared to last year’s plan. Chair
McGill recalled that the District had included a regulatory placeholder of $32 million in
the out years of the plan last year. Ms. Farrell responded that staff is concerned that
this may not be enough to cover the regulations as they have evolved since last year.
Of most concern are the new emission guidelines for existing sewage sludge
incinerators, which currently have a compliance schedule of three to five years and,
thus, will need to be implemented within the scope of the Ten-Year Plan. This could
cost significantly more than the $32 million figure from last year, given that the
proposed mercury limits are much lower than expected. Less certain but more likely
than was expected last year at this time is a requirement to remove ammonia and
possibly nitrogen from the District’s effluent. Staff is preparing capital planning
scenarios to address these regulatory initiatives, which will be presented to the
Committee at its December 8, 2010 meeting and to the full Board at a workshop
scheduled for December 16, 2010.
COMMITTEE ACTION: Received the report.

Take -aways from
NACWA Nutrient Summit
The road will be long and not easy and we need to prepare for
discussions:
• Know our Waters
• Get Uses Right
• Clarify and Improve Existing tools
• Nonpoint Source Folks Should Participate Meaningfully
3
Take -aways from
NACWA Nutrient Summit
(continuing)
• Explore the Range of Control Approaches
• Implement Goals through Adaptive Management
• Express Permit Limits with some Flexibility
• Incorporate Analysis of Costs and Benefits
Conference call on Nov 3rd & A white paper will be coming from NACWA

L —NPDES permit expires March 31,2012
G,L
• Sac Regional draft permit is causing us
concern
• Likelihood of nitrification and possibly
de- nitrification is increasing as scientific
evidence accumulates
• Ten Year Capital Improvement Plan will
include some funding scenarios for
ammonia and nitrogen removal to examine
impact on rates
5
Sludge becomes Solid Waste under
r —Clean Air Act...
"Y ` . New sewage sludge incinerator regulations for
existing and new incinerators
• Multiple hearth regulations for existing units
will require upgrades to remove HCI and Hg
which are not entirely proven
• Replacement with new fluidized bed reactors
will be evaluated but likely not feasible /cost
effective
• Compliance must be funded....cost figures will
be incorporated in Ten Year Capital Plan
• Time for compliance is 3 -5 years and will be a
challenge 6

• • \.
—AB32 Green House Gas Bill
-L.
• Likely not to be repealed by Proposition 23
• District may be able to avoid reductions by
staying under 25,000 ton limit....means
running cogeneration at reduced capacity and
buying clean power off grid
• Regulations are in abeyance awaiting
Proposition 23 outcome
• For this year's plan will assume no capital
expenditures and that any reductions will be
achieved by purchasing carbon offsets on the
open market
7
SFRWQCB 13267 Letter
Requirements
• New annual SSO reporting procedures and
requirements
• Electronic reporting
• Additional information on number, volume,
location and causes of SSOs
• Trend analysis compared to previous years
• Explanation of how Capital Program is
prioritizing and addressing defects will likely
be a requirement

r--Improvement Plan Funding Needs....
• Reviewed with Committee on December 8,
2010
• Presented to full Board on December 16,
