LAC 33:IX.4701. What are the purpose and scope of this Subchapter?

A. This Subchapter establishes requirements that apply to the location, design, construction, and capacity of cooling water intake structures at new facilities. The purpose of these requirements is to establish the best technology available for minimizing adverse environmental impact associated with the use of cooling water intake structures. These requirements are implemented through LPDES permits issued in accordance with Section 402 of the CWA, under the assumption of the NPDES program. B. This Subchapter implements Section 316(b) of the CWA for new facilities. Section 316(b) of the CWA provides that any standard established in accordance with Section 301 or 306 of the CWA and applicable to a point source shall require that the location, design, construction, and capacity of cooling water intake structures reflect the best technology available for minimizing adverse environmental impact. C. New facilities that do not meet the threshold requirements regarding amount of water withdrawn or percentage of water withdrawn for cooling water purposes in LAC 33:IX.4703.A must meet requirements determined on a case-by-case, best professional judgment (BPJ) basis. D. Nothing in this Subchapter shall be construed to preclude or deny the right of any state or political subdivision of a state or any interstate agency under Section 510 of the CWA to adopt or enforce any requirement with respect to control or abatement of pollution that is more stringent than those required by federal law.
