California Wastewater Utilities Appeal Suit Over CWA Permit Test Method

摘要

California wastewater groups will ask the U.S. Court of Appeals for the 9th Circuit to block the state from using a contentious Clean Water Act (CWA) test method to measure compliance with facilities' discharge permits, potentially teeing up a precedential decision on utilities' claim that the method falls short of regulatory standards. The plaintiffs in Southern California Alliance Of Publicly Owned Treatment Works (SCAP), et al, v. EPA filed a notice of appeal on March 21, signaling that they will seek to overturn a decision by a federal district judge that rejected their challenge to use of the test of significant toxicity (TST) as untimely.
