EPA proposes fish safety rules under 316(b)

The U.S. Environmental Protection Agency proposed standards to protect fish and other aquatic organisms based on the Clean Water Act.  So who is affected?  Existing facilities that withdraw at least 25 percent of their water exclusively for cooling purposes OR have an intake flow of greater than 2 MGD would be required to reduce fish impingement.  Comanies have the option of conducting monitoring to show the specified performance standards for impingement mortality of fish and shellfish have been met in order to satify the new standards.  The proposed action calls for companies to change any open loop cooling systems to closed.  Simply they are requiring large building to have cooling towers and recirculate water, rather constantly drawing from local water resources.

This will be a 90-day comment period then a final action must be taken by July 27, 2012.
