SUBJECT:	Summary of American Fisheries Society (AFS) 2011 Symposium

In support of the 316(b) rulemaking, Tetra Tech attended the American Fisheries Society's (AFS) annual meeting in Seattle, Washington on September 5[th] and 6[th], 2011.  The symposium was sponsored by the AFS Bioengineering Section.  The Monday session started at 1:15 PM with an introduction and presentation by Doug Dixon (EPRI) on the draft 316(b) rule for existing facilities.  The first session ended at 5:15 PM, and the symposium resumed at 8:00 AM on Tuesday and continued until 3:00 PM.  There were a total of 37 platform presentations.  Although it is somewhat difficult to categorize all presentations, the majority focused on intake technologies, impingement/entrainment surveys, source water surveys, and economic benefits.  Most speakers were representing engineering/consulting firms or utilities.

Attached to this memo is a summary of the symposium, including abstracts from each presentation.

One presentation was of particular interest to EPA; it was titled "Abundance and Composition of Fish and Shellfish Impinged and Entrained at Power Plant Intakes Based on a Survey of Over 220 Power Plants" and was presented by Greg Seegert of EA Engineering.  EPA followed up with Mr. Seegert and the sponsor of the research, Doug Dixon of EPRI.  The EPRI document upon which the presentation is based is also attached, as well as an additional analysis provided by EPRI.
