SUSTAINABILITY, U.S. CLEAN WATER ACT 316(B) FINAL REGULATIONS, AND BEST TECHNOLOGIES AVAILABLE FOR DESIGN OF WATER INTAKE STRUCTURES
Author : MAHMOOD NAGHASH
The U.S. Environmental Protection Agency (EPA) Section 316(b) guidelines for facilities with cooling water intake structures require that the location, design, construction, and capacity of intake structures reflect the best technology available (BTA) to minimize harmful impacts on the environment. EPA asserts that the withdrawal of cooling water by facilities removes billions of aquatic organisms from waters of the U.S. each year, with most impacts to early life stages of fish and shellfish through impingement and entrainment. The EPA 316(b) regulations for new facilities have been complied with since its inception in 2001 and guidelines for existing facilities was finalized in July 2014 after over a decade long reviews and court appeals (EPA 2014). EPA has identified 3 technologies as pre-approved BTA for new facilities which include i) closed-cycle cooling systems, ii) offshore velocity caps, and iii) reduced intake velocities. For existing facilities there are 4 additional technologies to comply with in modifying the existing intake systems. Among the 3 pre-approved BTA the closed-cycle cooling water system is the EPA’s preferred due to its substantial reduction in water withdrawal from natural waters. The other two pre-approved EPA
