While it is readily apparent that the physical and biological characteristics of a source water body at any given location are site-specific, some general characteristics typical of the broader classifications of different types of seawater (i�e�, open ocean, bays and estuaries, or even existing power plant outfall water) are summarized in the following sections�
Power Plant Discharge Water.
Using the discharge water from an existing coastal power plant (which uses seawater for cooling) as the feed water for a desalination facility eliminates con- struction impacts and typically will not introduce any new operational impacts� Shunting water through a desalination facility does nothing to increase the impingement and entrainment already associated with the operating power plant's circulating water system and routing the membrane concentrate into the existing discharge pipe helps to dilute and disperse it� Environmental concerns are typically associated with the impact on local biota of potentially for extending the operating life of the intake after the power plant has been decommissioned�
Vertical traveling screens are physical barriers designed to prevent passage of fish and debris into the water intake system� It is a standard feature at most power plant intake structures in the U�S� The ability of traveling screens to act as a barrier to fish without impinging depends on many site-specific factors, such as the size of the impinging fish, location of the screens, and presence of escape routes� It is considered advantageous to locate
Fine-mesh traveling screens have been installed at a few large-scale steam electric power plant cooling water intakes� Each screen basket is equipped with a water-filled lifting bucket that safely retains collected organisms as they are carried upward with the rotation of the screen� The screens are designed to operate continuously to minimize impingement exposure time� As each bucket passes over the top of the screen fish are rinsed into a collection trough by a low-pressure

Despite the U.S. holdout from the Kyoto Protocol, an increasing number of North American cities - such as Chicago, New York, and Vancouver - are making plans to address GHGs, including measuring local GHG emissions and identifying major sources of GHGs (such as factories, power plants, and
Common sites for brownfields include areas formerly used as dry cleaners, gas stations, industrial factories, and power plants.
increasingly aware of the environmental impact of these infrastructure and public services, such as the pollution generated by power plants and the ecological issues associated with water usage.
✓ Electrical generation facilities: These facilities transform raw sources of energy into electricity; they include plants that are powered by coal, oil, or natural gas, as well as hydroelectric and nuclear power plants.
In many cases, cities are served by power plants that are located dozens or hundreds of miles away.
