FROM: James D. Herberg, General Manager
Originator: Celia Chandler, Director of Human Resources
SUBJECT: LABOR RELATIONS — CONTRACT NEGOTIATIONS
GENERAL MANAGER'S RECOMMENDATION
Authorize the Board Chair to execute an agreement with the external Chief Negotiator
selected by the Ad Hoc Committee.
SUMMARY
BACKGROUND
On January 27, 2016, the Steering Committee approved the formation of an Ad Hoc
Committee for the purpose of interviewing and selecting an external Chief Negotiator
for the upcoming contract negotiations with all six (6) bargaining units at the Orange
County Sanitation District.
The Ad Hoc Committee consists of the Board Chair, the Board Vice-Chair, and the
Administration Committee Chair. The Ad-Hoc Committee is meeting to interview and
select from the following list of firms:
• Liebert, Cassidy, &Whitmore
• Rutan & Tucker
• Filarsky & Watt
• Andleson, Atkinson, Loya, Ruud, & Romo
On February 19, 2016, the Ad Hoc Committee conducted interviews with the firms.
The Committee will report their recommendation to the Steering Committee and the
Board of Directors at their regular February 24, 2016 meetings.
RELEVANT STANDARDS
• Highly qualified, well trained, motivated, and diverse workforce
• Competitive compensation and benefits
• Positive employer, employee relations
• Negotiate fair and equitable labor agreements
Page 1 of 3
PROBLEM
Contract negotiations are expected to begin with all six (6) bargaining units prior to the
expiration of their respective MOU's in June, 2016. In preparation for the upcoming
negotiations, the OCSD labor negotiations team and OCSD's Chief Negotiator will
need to work closely with board leadership to set parameters and develop negotiation
strategies.
PROPOSED SOLUTION
Authorize the Board Chair to execute an agreement with the external Chief Negotiator
selected as by the Ad Hoc Committee Chief Negotiator selection process in
accordance with Ordinance NO. OCSD-47, Section 3.03.E Contractors Reporting to
the Board.
OCSD-47 is an ordinance of the Board of Directors of the Orange County Sanitation
District establishing requirements and procedures forthe purchase of goods, services,
and public works projects. OCSD-47 Section 3.03.8 Contractors Reporting to the
Board, lists that the provisions listed under Article 3 (Professional Services), shall not
apply to the retention of Professional Service firms or individuals that are selected by
the Board and report directly to the Board. For such contracts, the Board shall
determine the method of selection, consistent with the requirements of applicable law.
TIMING CONCERNS
On June 30, 2016, the Memorandums of Understanding (MOU's)with all six (6)of the
OCSD's bargaining units will expire. It is anticipated that the selection of the Chief
Negotiator will be presented to the Board of Directors for consideration and
authorization during the February, 2016 Board Meeting, leaving approximately four(4)
months for preparation and negotiation once the Chief Negotiator is hired.
PRIOR COMMITTEE/BOARD ACTIONS
On January 27, 2016, the Steering Committee formed an Ad Hoc Committee for the
purpose of interviewing and selecting an external Chief Negotiator for the upcoming
contract negotiations with all six (6) bargaining units at the Orange County Sanitation
District.
ADDITIONAL INFORMATION
On June 30, 2016, the Memorandums of Understanding (MOU's) with all six (6) of the
Orange County Sanitation District bargaining units will expire. Three (3)of the bargaining
units are represented by the Orange County Employees Association (OCEA). OCEA
represents 96 OCSD employees, who perform paraprofessional and administrative jobs.
One (1) bargaining unit is represented by the International Union of Operating Engineers
- Local 501 (Local 501). Local 501 represents 191 OCSD employees, who perform
operations, maintenance and other trade-related jobs. The remaining two (2) bargaining
Page 2 of 3
units are represented by the Supervisor and Professional Management Group (SPMT)
affiliated with the American Federation of State, County and Municipal Employees
(AFSCME). SPMT/AFSCME represent 55 OCSD employees that are responsible for
supervisory duties across all Divisions. In addition, SPMT/AFSCME represent 192 OCSD
employees holding professional, exempt-level positions who perform analytical work.

FINANCIAL CONSIDERATIONS
It is estimated that the cost for labor relations consulting for all negotiations will total
$60,000.

Ordinance OCSD-47 Section 3.03 B, Contractors Reporting to the Board. This item has
been budgeted. (Line item: FY 2015-16 Budget Section 53256).

Orange County Sanitation District
FROM: James D. Herberg, General Manager
Originator: Robert P. Ghirelli, Assistant General Manager
SUBJECT: ALTERNATIVE APPROACHES TO INTEGRATED REGIONAL WATER
MANAGEMENT
GENERAL MANAGER'S RECOMMENDATION
Information Only.
SUMMARY
BACKGROUND
The CA Department of Water Resources (DWR) manages an Integrated Regional
Water Management (IRWM) Program for the purpose of allocating Prop. 84 and
Prop. 1 water bond grant funds. DWR specifies grant allotments to 12 funding areas
statewide; north central Orange County is part of the Santa Ana watershed funding
area, along with portions of Riverside and San Bernardino counties. The Santa Ana
Watershed Project Authority (SAWPA) administers the grant program in this funding
area. Approximately$63 million dollars in grant funds will be made available in 2017
to fund IRWM projects in the Santa Ana funding area.
RELEVANT STANDARDS
• Constantly identify and implement increases in efficiency
• Support OCWD expansion of GWRS
• Secure outside funding (grants)for recycled water or other capital program
• Maintain collaborative and cooperative relationships with stakeholders
PROBLEM
There needs to be a more equitable process for allocating grant funds to ensure
each region within the funding area receives its fair share of the available monies.
For example, Orange County might garner a greater share of grant funds if the
allocation formula was based on land area and population.
Page 1 of 2
PROPOSED SOLUTION
Representatives of several Orange County agencies are discussing and evaluating
options to work with SAWPA on alternatives to the current allocation process.
OCSD is one of several entities (along with the County of Orange, Irvine Ranch
Water District, and Orange County Water District) proposing to engage SAWPA and
its member agencies in a discussion to refine the IRWM funding process for Prop. 1.
The goal is to work in a cooperative fashion with our SAWPA partners to put in place
an allocation formula that is a more participatory and transparent process for funding
projects within the Santa Ana funding area.
TIMING CONCERNS
With the next round of Prop. 1 funding less than a year away, it is important to
engage SAWPA now to increase the likelihood that an alternative funding approach
is in place to guide the 2017 grant allocations. The joint OCSD/OCWD effluent
reuse study will be complete in summer 2016 and may recommend construction of
projects that could be eligible to receive grant funds in the next round of funding.
RAMIFICATIONS OF NOT TAKING ACTION
Failure to seek a change in the IRWM funding process could mean Orange County
misses out on receiving millions of dollars in Prop 1 grant funds that would otherwise
be spent on projects outside Orange County.
