Decision concludes a permit is required if such discharges are the “functional equivalent” of a direct discharge to navigable waters.

On April 23, 2020, the Supreme Court of the United States issued an opinion in County of Maui, Hawai’i v. Hawai’i Wildlife Fund, holding that the Clean Water Act (CWA) requires a permit for certain discharges through groundwater. Specifically, a permit is required if there is a “direct discharge” from a point source to navigable waters, or if a given discharge is the “functional equivalent” of a direct discharge when that discharge passes through groundwater before reaching navigable waters.[1]

In establishing this new functional equivalence test, the Court rejected both the argument that allowing any regulation of discharges through groundwater would expand the CWA’s scope without warrant, and the contrary argument that every discharge that is “fairly traceable” from a point of discharge to navigable waters must be regulated under the CWA. When applying the test, the Court explained that several factors — most centrally, time and distance — are relevant to determining whether a discharge through groundwater is the functional equivalent of a direct discharge.

The proposed federal permitting regime includes some surprising provisions, including no permit expiration and no proposed application deadline for most units.

On December 19, 2019, the US Environmental Protection Agency (EPA) released a proposed rule to establish a federal permitting program under the Resource Conservation and Recovery Act (RCRA) for the disposal of coal combustion residuals (CCR), also known as coal ash, in surface impoundments and landfills. EPA’s 2015 CCR rule established self-implementing requirements for the management of CCR. In 2016, Congress passed the Water Infrastructure Improvements for the Nation (WIIN) Act, which authorized states to submit for EPA approval state CCR permit programs to implement the federal CCR rule requirements. The WIIN Act also required EPA to implement a federal CCR permit program in Indian country and in states that do not have an approved permitting program.

The proposed rule, titled Hazardous and Solid Waste Management System: Disposal of Coal Combustion Residuals from Electric Utilities; Federal CCR Permit Program (Proposed CCR Permitting Rule), would establish this federal permitting backstop.
