The Southern Environmental Law Center (SELC) appealed to the Eleventh Circuit a Southern District of Georgia ruling that enjoined the Clean Water Rule (2015 Rule), a 2015 rulemaking by EPA and the U.S. Army Corps of Engineers (Corps) re-defining “Waters of the United States” under the Clean Water Act. Several states challenged the 2015 Rule and the court’s injunction applies to each of the petitioning States: Alabama, Florida, Georgia, Indiana, Kansas, Kentucky, North Carolina, South Carolina, Utah, West Virginia and Wisconsin. SELC intervened in the litigation, arguing that the 2015 Rule is necessary to protect waters and wetlands under the Clean Water Act. The district court, however, agreed with the state petitioners in finding that they were substantially likely to demonstrate that the 2015 Rule exceeded EPA’s authority. Even without the court’s injunction, however, the 2015 Rule will not take effect in any state as EPA has delayed its effective date until 2020. Environmental groups are challenging the regulation delaying the effective date in New York, South Carolina and Washington federal district courts. The United States is not appealing the Georgia district court’s injunction. Instead, it has argued that courts should defer ruling on challenges to the 2015 Rule until EPA and the Corps can finish their reconsideration process.
