Cooling Water Intake Structures

Brief description of the federal cooling water intake structure rule and implementation activities.

Section 316(b) of the Clean Water Act requires EPA to issue regulations on the design and operation of intake structures, in order to minimize adverse environmental impacts. The goal is to reduce impingement mortality and entrainment of fish and other aquatic organisms at cooling water intake structures (CWISs) used by certain power generation and manufacturing facilities for the withdrawal of cooling water from waters of the United States (WOTUS). EPA published a final regulation to establish Section 316(b) requirements for Phase II (existing) facilities on August 15, 2014 (Final Rule).

316(b) Stakeholder Meeting

TCEQ scheduled a series of stakeholder meetings to discuss and obtain feedback on TCEQ guidelines for implementing Section 316(b) of the Clean Water Act and future revisions to application worksheets. The most recent meeting was Wednesday, December 14, 2016 at the TCEQ offices in Austin, Texas. Any future meetings will be announced when scheduled.
