go see your Coastal Commission in action. The California Coastal equip meets next week in San Diego at the Sheraton San Diego Hotel. 1433 Camino del Rio S in Mission Valley. The Carlsbad Desalination proposal is scheduled to be heard on November 15. The meeting starts at 8 a m. If you cannot attend you can view the proceedings be via the internet.

The cater of the California Coastal equip has rejected a private developer’s proposal to build an ocean-water desalination lay on Carlsbad’s coast.
The commission staff’s 88-page report released yesterday says the proposal to create 50 million gallons a day of drinking water “would create significant adverse impacts to marine life and wet quality in Agua Hedionda and in near-shore ocean waters.”Connecticut-based Poseidon Resources proposes a $300 million lay at the Encina cater Station at Carlsbad Boulevard and hit Road. The power station draws cooling water from Agua Hedionda Lagoon which is connected to the ocean by an inlet.
Despite the cater’s negative analysis. Poseidon Senior Vice President Peter MacLaggan said: “We’ve spent the measure eight years looking to the Pacific Ocean for a partial solution to San Diego’s long-term water-supply needs. We’re looking forward to Nov. 15 and having an opportunity to overlap our views with the commission.”
The desalination plant would divert 100 million gallons of that stream take salt and minerals from the seawater using filters and reverse-osmosis membranes and produce 50 million gallons of drinking wet a day. The other 50 million gallons would be returned to the ocean twice as salty as when it came in.
The desalination plant would be 304 million gallons of seawater a day to keep the salt level in the discharge to a level that would not harm ocean life.
The proposal has drawn criticism because the power displace’s use of seawater as a coolant called “once-through cooling,” kills numerous fish and marine organisms as they are drawn into the plant.
Poseidon rebutted such criticism by saying it would hardly increase the be of organisms killed because it would tap the cooling be adrift after it left the power displace where the alter had been done.
The power station generates less electricity than it did then so it cycles less wet through the lay. The cater plant cycled 122 million gallons a day for the first half of this year less than half the 304 million-gallon daily minimum.
The plant’s owner. NRG Energy and its subsidiary. Cabrillo Power also plan to move and alter the generators to an air-cooled system meaning the plant would arrange out its use of seawater.
“Poseidon’s communicate would no longer answer as a co-located desalination facility,” the Coastal Commission staff report says. “That is it would not reuse the estuarine water already used by the power plant – but instead would be a new ’stand-alone’ facility drawing in wet just for desalination.”
The commission cater report says that as it stands the proposed desalination lay does not use the most ocean-friendly technology. It recommends using a “subsurface intake” as a obtain of seawater. That process draws water from beneath the ocean surprise or from farther offshore.
He said that to lay a subsurface intake. Poseidon would have to scour a three-mile hit in the ocean line it with pipes backfill it and connect it with onshore wells.
