Hydrolox Screens: Best Technology Available for 316(b)
Section 316(b) of the EPA's Clean Water Act requires that the location, design, construction, and capacity of cooling water intake structures reflect the best technology available (BTA) for minimizing adverse environmental impacts - impingement and entrainment. Under the terms of the rule, Hydrolox traveling water screens qualify as a BTA for minimizing impingement mortality ("modified traveling screens"). Specifically, the EPA noted that Hydrolox screen designs have "shown promise in reducing impingement mortality".
Hydrolox Series 6000 Vertical Traveling Water Screen with Ristroph-Style Fish Collection Buckets
Equipped with Ristroph-style fish
collection buckets, a low-pressure wash, and a fish handling and return
system, Hydrolox traveling water screens are a powerful solution for
enabling compliance with Section 316(b) of the Clean Water Act:
Section 316(b) applies to roughly 1,065 electric power plants, chemical
manufacturers and petroleum refiners in the United States that withdraw
at least two million gallons of cooling water per day and use at least
25 percent of that water for cooling purposes. The final Section 316(b)
ruling was published to the Federal Register on August 15, 2014 and
became effective on October 14, 2014. For more information about the
EPA's Section 316(b) of the Clean Water Act, visit the the EPA's website.

Power Research Institute's (EPRI) report, "Hydrolox Traveling Water
Screen Fish Impingement and Survival Case Study: Plant Barry Generating
Station", evaluates the survival of fish exposed to a Hydrolox
traveling water screen specifically designed to protect juvenile and
adult fish at Alabama Power Company's Plant Barry Generating Station.
