McAfee & Taft RegLINC - September 2011: Recent developments under the Clean Water Act: Proposed rule modifies cooling-water intake unit requirements by Jessica John Bowman

Section 316 governs the design, construction and use of cooling water intake structures, requiring that the “location, design, construction, and capacity” of such structures “reflect the best technology available for minimizing adverse environmental impact.” The proposed rule is designed to mitigate the impact of cooling water intake structures on fish and wildlife populations. In the ordinary course of operations, cooling water intake structures present a risk to fish, shellfish, and other wildlife; specifically, the cooling intake unit may impinge or entrain such organisms, causing fatalities and adversely affecting the ecological makeup of the body of water from which the water is drawn.

Facilities Subject to the Proposed Rule
