The San Diego Regional Water Quality Board unanimously approved a plan today to build a desalination plant in Carlsbad capable of producing 50 million gallons of drinking water a day.
Poseidon Resources, the project's developer, said the decision clears the way for construction on the desalination plant to begin.
"Today's decision successfully brings to a close the project's six-year permitting process that included more than 14 public hearings and over 70 hours of public testimony and deliberation," according to a statement issued by Poseidon Resources.
"Poseidon has now received every regulatory agency approval necessary to start project construction," it continued.
The company said it hopes to complete the more than $300 million project - which will be located adjacent to the Encina Power Station at Agua Hedionda Lagoon - by 2012.
When it's finished, the desalination plant will be capable of converting enough ocean water into drinking water to meet the needs of 300,000 residents, about 50 million gallons a day.
To mitigate any environmental impacts from the project's, the SDRWQB required Poseidon Resources to create 55.4 acres of coastal wetland habitat in Southern California.
The SDRWQB's decision comes one day after a Superior Court judge ruled against two environmental groups who sued in an effort to halt the construction of the desalination plant.
