Clean Water Act Tag

If a state or local government discharges a pollutant from a point source to a navigable water it must obtain a permit under the Clean Water Act (CWA). But what if that pollutant is conveyed in something—say groundwater—between the point source and the navigable water? Must the state or local government still obtain a permit? That is the question the Supreme Court will decide next term in County of Maui, Hawaii v. Hawaii Wildlife Fund. Maui County injects treated wastewater from wells into the groundwater. Some of the treated wastewater reaches the Pacific Ocean. The Hawaii Wildlife Fund sued the County arguing it was required to obtain a permit under the CWA for these discharges.

The Trump administration asked the Supreme Court to hold “in abeyance” litigation over whether a federal district court or a federal court of appeals has jurisdiction to rule whether the current 2015 Waters of the United States (WOTUS) definitional rule violates the Clean Water Act. On April 2, 2017 the Supreme Court denied the motion, allowing the litigation to proceed. President Trump’s February 28, 2017 executive order Restoring the Rule of Law, Federalism, and Economic Growth by Reviewing the "Waters of the United States" Rule calls for the “rescinding or revising” of the WOTUS rule. Many state and local governments objected to the broad nature of this rule, in particular to the expansive definition of ditches and the ambiguous definition of tributaries.
