Environmentalists May Challenge Desal Project Approval

The California Coastal Commission voted last night to approve the largest desalination project in the country.   Poseidon Resources says it's now on track to build the $300 million plant in Carlsbad next year. But environmental groups may challenge the project in court. KPBS reporter Ed Joyce has details.

The company says it will convert seawater to 50 million gallons of drinking water each day.

Poseidon VP Peter Maclaggan says construction of the plant could start next year and water could be delivered to users by 2010. But environmental groups may try to block those plans.

Mark Massara, director of the Sierra Club's California Coastal Program , on the chances for a legal challenge.

Massara : I'd say it's a virtual certainty given the massive unaddressed questions and information inadequacies that are still associated with the project."

He says Poseidon needs to do more studies to determine how the plant's operations would affect the marine habitat. Coastal commission staff recommended commissioners reject the project. They say the plant's electricity use would increase greenhouse gas emissions -- and Poseidon's plan to offset those emissions isn't good enough.
