PERMITTING PROCESS
STRATEGY
Two tier permitting strategy:
Accelerated and Traditional
dual paths.
Working with:
TWO TIER PERMITTING PROCESS STRATEGY
ACCELERATED
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;
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).
TWO TIER PERMITTING PROCESS STRATEGY
TRADITIONAL (would conduct all 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.
