Dependence on rainfall and riverwater
for water supply
Repetitive droughts strained the water
supply
Brackish water desalination plant added
as supplement
Water availability too low to supply local
communities and required expensive
supplemental long-haul trucking
Situation unlikely to improve naturally
Long-term, affordable & sustainable
water supply is required

CARBON-FREE DESALINATION PROCESS
Preliminary assessement based
on the Project International
Standard - Part 2 (ISO 14064-2)
on the Oneka Technology
New study planned in 2023
Saves about
1 m3/d of desalinated water produced = 0.75 to 1 ton of CO2e per year Compared to fossil-fuel powered high efficiency desalination (with ER) Small community project example
3500 m3/d project (for Fort Bragg)
(640 gpm)
2500 to 3500 T of CO2e saved per year
Large project
185,000 m3/d for larger city needs
(50 MGD )
140,000 to 185,000 T of CO2e saved per year
AVOIDED CARBON EMISSIONS:
No Land or Visual Impact

Result
The salinity variation is extremely limited Localised salinity increase can be significant in some cases 60-micron-size intake holes to prevent harmful
impact on ecosystems (adjustable)
60 micron is smaller than nearly all fish larvae

Pilot Project permitting
The California Ocean Plan’s Desalination Amendment (OPA) provisions don’t apply with the following conditions :
<
OPA Criterion (at M.1.a.) Oneka Pilot Project
Satisfies Criterion?
“desalination facilities that are operating to serve as a critical short-term water supply during a state of emergency declared by the Governor” Yes portable desalination facility Yes
withdraw less than 0.10 MGD Yes
operated by a governmental agency Yes
Oneka is working with
governments and local
agencies to minimize
negative impacts and
maximize positive
impacts of each project
we undertake.
Building and implement
best practices and
strong relationship with
local communities is
central to our permitting
process.
GENERAL PERMITTING PROCESS SUBJECTS
ENVIRONMENT:
OCEAN - BEACH & COAST
CONCESSIONARY RIGHTS
NAVIGATION SAFETY
HEALTH
• Hard bottom impacts
• Brine
• Animal Entanglements
• Intakes
• Location
• Ocean, coastal and land use
KEY CONCERN(S)
• Navigation international codes
• IMO safety standards
• Water quality
• WHO standards
Use the pilot project to conduct studies
Potential studies that could be conducted concurrently
1. Entrainment Study. A technical, field sampling study to determine what impact the seawater withdrawal will have on the plankton resources that include fish larvae.
2. Benthic Habitat Survey. A sonar survey of the seafloor to document the area’s habitat to determine what type of seafloor habitat is present (rocky reef, kelp, sandy bottom, or some combination).
3. Water Need. Ideally this must be cataloged in a water planning document from the local water authority.
4. Subsurface Intake Feasibility. The Oneka buoy includes an integrated surface water intake. Therefore, before it can be used, at least at utility scale, the feasibility of a subsurface intake must be determined.
5. Brine Discharge Technology Empirical Study.
6. Essential Fish Habitat Assessment. A review by the National Marine Fisheries Service to ensure the project does not have an adverse impact on any Federally managed fisheries.
7. Sensitive Species Survey. A survey to ensure the installation and operation will not adversely impact any sensitive species in the area.

Pilot Project permitting
The California Ocean Plan’s Desalination Amendment (OPA) provisions apply to the buoys under most circumstances. Under the two following conditions the OPA would not apply:
1. “desalination facilities that are operating to serve as a critical short-term water supply during a state of emergency declared by the Governor” would not need to comply with any of the OPA;
The unit of the pilot project would be sold to the city of Fort Bragg who would also own it (exception to typical business model)
2. “portable desalination facilities that withdraw less than 0.10 (MGD) of seawater and are operated by a governmental agency” would not need to comply with the OPA in the following sections:
o Chapter III.M.2 (Water Code section 13142.5(b) Determinations for New and Expanded Facilities: Site, Design, Technology, and Mitigation Measures Feasibility Considerations),
o Chapter III.M.3 (Receiving Water Limitation for Salinity), and o Chapter III.M.4 (Monitoring and Reporting Programs).
