3 Cargill and the Bay Area
4 Solar Sea Salt Production –
Long History in the South Bay
5 Cargill’s solar sea salt facility
in Newark is the only large-
scale manufacturer of food-
grade sea salt in the United
States
6 Nourishing, protecting and enriching the Bay Area community where we live and work.
Cargill’s Community Commitment
7 • Cargill provides 200 union and management jobs at its Newark facility. • Whether participating in volunteer events at the refuge, collecting and sorting food for those in need, or investing in local STEM programs for local students, Cargill employees demonstrate their commitment to the local community.
• Over the last five years, Cargill’s Bay Area operation has donated more than $1.5 million and hundreds of volunteer hours to local nonprofits.
• Nonprofit include Second Harvest Food Bank, San Francisco Bay Wildlife Society, Ducks Unlimited, LOV of Newark, Abode Services Fremont and many others. • Cargill was recently recognized by Ducks Unlimited for a partnership to deliver a program that brings Bay Area middle school and high school students out to the San Pablo Bay National Wildlife Refuge.

Cargill’s proactive approach
Addressing Sea Level Rise
9 • Climate change and sea level rise will impact all of us.
• The time to act is now so we can protect the Bay
and the communities where we live and work.
• Cargill is addressing sea level rise and protecting the Bay for future generations by enhanced processing
and removing the natural mixed sea salts from our
Newark facility.
• Cargill is partnering with EBDA to safely return the
mixed sea salts back to the Bay.
Options Considered for Mixed Sea Salt Post-Harvest
•Land‐based options
• Leave it place (local cap‐in‐place)
• Risk due to proximity to the Bay;
permitting challenges
• Truck to landfill
• High GHG emissions; additional local
traffic; long time frame
• Truck or train to underground
injection control well
• High GHG emissions; additional local
traffic
•Bay/Ocean‐based options
• Barge to deep‐water ocean
• High GHG emissions; requires legislative act
• Direct discharge to the South Bay
• Dramatic increase in Bay water use
• Discharge to the Bay by connecting to
EBDA pipeline system
• Limited GHG emissions
• Marginal increase in Bay water use
• Use EBDA’s existing infrastructure/permit

Proposed Project Overview
13 • Cargill would construct pipeline and connection to EBDA • Route and connection point will be discussed later in this presentation • Cargill will execute Project Labor Agreement with Building Trades for pipeline construction
• Average of 1‐2 MGD of brine would be discharged to EBDA year‐round • Brine discharges would be paused in the event of EBDA capacity constraints • Wet weather
• Process upset
• Water quality would be monitored to ensure compliance • Discharges would continue in the long term, until the current MSS has been harvested and discharged, with an expected timeline of 10‐15 years.

New Pipeline
Cargill Goals: Adaptation, Resilience, and Sustainability 15 •Reduces risk of a release of brine due to sea
level rise
•Sustainable discharge of MSS brine utilizing
EBDA’s existing effluent and deep‐water
outfall
•Enhanced harvesting of commercial product
•Partner with EBDA, as a long‐term
customer, to jointly create a solution to
adapt to sea level rise in a sustainable
manner
EBDA Drivers and Potential Benefits
16 •Sustainably manage discharge generated within EBDA’s service area •Utilize excess capacity available in EBDA’s existing infrastructure •Receive financial compensation that will offset EBDA expenses to the benefit of the Member Agencies’ ratepayers
•Benefit from new or improved infrastructure that will be more corrosion‐resistant and resilient to higher salt levels •Support efforts to improve resilience of SF Bay from sea level rise by facilitating removal of salts from Cargill’s MSS ponds adjacent to the Bay Pipeline, Construction & Route Specifics
• Cargill working with Hayward public works staff
and consultant on the pipeline route and
construction specifics
• 18” high‐density polyethylene (HDPE) pipeline
constructed within Union City’s public streets
• Pipeline buried 4‐6’ underground
• Both open trench and trenchless drilling will be
used to minimize impacts
• Proposed route provides for possibility of
concurrent installation of recycled water line and
installation of conduit for fiber optic cable
• Brine in pipeline under low pressure coupled
with corrosion resistant HDPE material minimizes
risk of leakage/spill
