Engineering Report Concludes:
"Wedgewire Screens Best Technology Available to Protect Hudson River Fish"
Albany, NY -The Entergy Corporation presented to the state Department of Environmental Conservation (DEC) on Friday the findings of an independent engineering firm and leading, nationally recognized biological experts that Wedgewire and underwater screens technology would be superior to cooling towers for protecting Hudson River aquatic life near the Indian Point Energy Center.
The filing is in response to a request from the DEC relating to a water discharge permit proceeding. The DEC required Entergy to make a filing on the feasibility of cooling towers as well as present alternate technologies of comparable effectiveness. In its filing, Entergy has asked the DEC to issue a revised draft permit that includes the Wedgewire technology in April.
After a rigorous and thorough study, an engineering firm commissioned by Entergy, Enercon, and its leading nationally recognized biological experts concluded that Wedgewire screens would better protect fish eggs and larvae over the 20-year period of a renewed Indian Point license in large part because they can be installed and operational 12 to 15 years sooner than cooling towers.
Moreover, unlike Wedgewire systems that operate beneath the surface of the river with no harmful emissions, the massive cooling towers would emit approximately 100 tons of particulate matter a year of air pollution. Particulate matter are considered among the leading environmental causes of respiratory illness, especially among the very young and the elderly.
Wedgewire screens is a technology that is growing in popularity with hundreds in operation worldwide and in the US, including The Charles Point Resource Recovery facility adjacent to Indian Point and an IBM facility on the Hudson River.
The Enercon study concluded that there is very little, if any, chance that the massive cooling towers could receive the necessary construction, rock blasting and zoning permits required from the Village of Buchanan, N.Y. Entergy could also encounter significant opposition to moving a major interstate pipeline that, according to its owner, supplies approximately 50 percent of New England's natural gas requirements to make way for the cooling towers.
