|Ocean Desalination Plants in Southern California
Right now Southern California has several large desal proposals in the works that are
important to keep an eye on:
The City of Huntington Beach approved both Poseidon's EIR and the Conditional Use
Permit (CUP) for their proposed 50 MGD plant. Over concerns that the EIR is inadequate,
both a CEQA lawsuit and a Coastal Commission appeal are moving forward.
The San Diego County Water Authority (SDCWA) released the EIR for their 50 MGD
proposed plant at the Encina Power Plant and opened and closed a public hearing.
However, the vote was delayed and is now scheduled for July 27th, 3pm and the SDCWA
offices. The SDCWA is also going to begin studies at the San Onofre nuclear power plant
and has allocated funds for these studies.
The City of Carlsbad and Poseidon approved the EIR and various permits for their
proposed 50 MGD plant at the Encina Power Plant. Local environmental organizations
are prusuing a CEQA lawsuit.
Below is a list of desal plants and associated companies, existing and proposed.
