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.

Over the course of 2018, Latham & Watkins lawyers reviewed all 57 California Environmental Quality Act (CEQA) cases, both published and unpublished, that came before California appellate courts. These cases covered a variety of CEQA documents and other topics. Below is a compilation of information from the review and a discussion of the patterns that emerged in these cases. Latham will continue to monitor CEQA cases in 2019, posting summaries to this
The Environment Agency has released data indicating that enforcement undertakings in England and Wales reached more than £2.2 million in 2018 — the highest-ever levels within a single year.
