In April 2020, two days before the U.S. Supreme Court issued its decision in County of Maui v. Hawaii Wildlife Fund, the United States Environmental Protection Agency (EPA) and the Department of the Army, Corps of Engineers (ACOE), published the Navigable Waters Protection Rule redefining the scope of waters subject to federal regulation under the Clean Water Act (Act or CWA).

The Act, which prohibits the discharge of any pollutant into “navigable waters” without a permit from the EPA under the National Pollutant Discharge Elimination System (NPDES) and the discharge of dredge or fill material into “navigable waters” without a permit from the ACOE under the Act’s Section 404 permit program, defines “navigable waters” as “the waters of the United States, including the territorial seas.” Although the Supreme Court has consistently held that the CWA’s jurisdiction extends beyond waters that are actually navigable, a clear definition of “waters of the United States” (WOTUS) has eluded lower courts and federal regulators since the Supreme Court decided Rapanos v. United States in 2006. In Rapanos, a plurality opinion by Justice Antonin Scalia interpreted WOTUS to cover relatively permanent or continuously flowing bodies of water connected to traditional navigable waters, as well as adjacent wetlands with a continuous surface water connection to these waters. Although concurring in the ultimate decision, Justice Anthony Kennedy wrote a separate opinion with a different interpretation of WOTUS, covering any wetlands that have a “significant nexus” with traditionally navigable waters. The 4-1-4 decision did not establish a clear precedent for the WOTUS definition.

In June 2015, the Obama Administration published the Clean Water Rule to clarify the WOTUS definition after questions arose over the government’s authority when confusion around the WOTUS definition stalled CWA enforcement actions. The Clean Water Rule looked to the Act’s objective “to restore and maintain the chemical, physical, and biological integrity of the Nation’s waters” and adopted Justice Kennedy’s “significant nexus” standard to implement this objective. The rule thus covered any waters that, either alone or in combination with similarly situated waters in the region, significantly affected the chemical, physical, or biological integrity of traditional navigable waters. It established six categories of waters that were jurisdictional by rule; specified waters that were excluded from CWA jurisdiction; and identified two categories of waters (similarly-situated regional waters and floodplain waters) that could be subjected to a case-specific significant nexus jurisdiction analysis.

The new Navigable Waters Protection Rule replaces the Clean Water Rule and, in doing so, shifts the emphasis of the WOTUS definition more in line with Justice Scalia’s plurality opinion in Rapanos. Under the new rule, jurisdictional waters “encompass relatively permanent flowing and standing waterbodies that are traditional navigable waters in their own right or that have a specific surface water connection to traditional navigable waters, as well as wetlands that abut or are otherwise inseparably bound up with such relatively permanent waters.” The new rule establishes four categories of jurisdictional waters: (1) the territorial seas and traditional navigable waters; (2) perennial and intermittent tributaries that contribute surface water flow to such waters; (3) certain lakes, ponds, and impoundments of jurisdictional waters; and (4) wetlands adjacent to other jurisdictional waters. All other waters or features are excluded from CWA jurisdiction.

This new rule will have the effect of further muddying the waters of CWA jurisdiction as the regulatory pendulum swings back once again, risking further confusion in an area where consistency and predictability are key. As the new rule reduces the Act’s reach over the nation’s waters, it is expected that it will also reduce the number of permits required under the NPDES and Section 404 permit programs. There are five lawsuits currently in federal court which are challenging the Navigable Waters Protection Rule, including a lawsuit in Massachusetts federal court.

We will continue to monitor judicial and administrative developments under the CWA as courts, the EPA, and the ACOE apply this new rule. For any questions regarding this evolving area of the law, please reach out to the attorneys at Mackie Shea Durning, PC.

In April, the United States Supreme Court issued a decision that could drastically expand the scope of activities requiring a permit under the federal Clean Water Act (CWA or Act). The case, County of Maui v. Hawaii Wildlife Fund, involved a wastewater reclamation facility in Hawaii that pumped treated waste water into groundwater injection wells, from which the effluent would enter groundwater and flow to the Pacific Ocean.

The Court held that, even though the effluent traveled through groundwater (a non-point source) before entering the ocean, this activity required a CWA permit, because it was “the functional equivalent of a direct discharge from the point source into navigable waters.” In doing so, the Court introduced a new test for determining whether indirect discharges, i.e., when point-source discharges of water pollution enters a non-point source (such as groundwater) before traveling to a water body covered by the CWA, required CWA permits.

The holding is particularly relevant to wastewater treatment facilities who pump treated effluent into groundwater wells, since that is the particular fact pattern at issue; however, it is also relevant to any point source discharger from whom pollutants could travel through groundwater or another non-point source into waters of the United States.

CWA Permitting and Application

The CWA prohibits the “discharge of any pollutant by any person” into the waters of the United States without that person obtaining a permit from the United States Environmental Protection Agency (EPA) under the National Pollutant Discharge Elimination System (NPDES). The Act defines “pollutant” broadly to include, among other things, any solid waste, sewage, and industrial, municipal, and agricultural waste discharged into water. A “discharge of a pollutant” is any addition of any pollutant to navigable waters from any point source. A “point source” is any discernible, confined and discrete conveyance, including but not limited to any pipe, ditch, channel, conduit, or well, from which pollutants are or may be discharged.

Less clear is whether, and to what extent, a NPDES permit is required for discharges of pollutants to non-point sources, such as groundwater. Regulation of groundwater has traditionally been left to the states and not the federal government under the Act. Practically speaking, non-point source pollution is rarely traceable to any single discrete source and is, therefore, difficult to regulate through individual permits.

Not too long before the Court’s decision, in November 2019, the federal court in Massachusetts acknowledged the ambiguity inherent in the CWA’s application to discharges of pollutants into groundwater. In Conservation Law Foundation, Inc. v. Longwood Venues & Destinations, Inc., the District of Massachusetts deferred to EPA’s April 2019 interpretative statement on the issue and held that “discharges into groundwater are categorically excluded from the CWA’s regulatory regime, irrespective of any hydrological connection to navigable waters.” Thus, the Supreme Court’s decision in County of Maui nullified what was the (not at all longstanding) prevailing law on this issue in Massachusetts.

The Court’s Decision and the New “Functionally Equivalent” Test

In County of Maui, a majority of the Supreme Court (in a 6-3 opinion written by Associate Justice Stephen G. Breyer) resolved the ambiguity by applying the CWA to certain discharges of pollutants to groundwater. Under the new test, the addition of a pollutant from any point source requires a NPDES permit when (i) a point source directly discharges pollutants into navigable waters, or (ii) the addition of the pollutants is “the functional equivalent of a direct discharge from the point source into navigable waters.”

Unfortunately, by resolving one ambiguity, the Court may have created more confusion instead of clarifying the law. The majority essentially staked a middle position between two arguments. The petitioner, the County of Maui’s wastewater treatment facility, argued for a bright-line “means-of-delivery” test where only direct discharges from a point source to a covered water required a permit, focusing on the manner in which the pollutant is conveyed to the covered water. The respondents, several environmental groups who filed a CWA citizen suit against the water treatment facility, argued for application of the Ninth Circuit’s “fairly traceable” test, which would have required a permit whenever pollutants are fairly traceable from the point source to a navigable water. The U.S. Solicitor General submitted an amicus brief in support of the petitioner and arguing for the application of the EPA’s April 2019 interpretative statement. The Court declined to grant deference to the EPA’s interpretation, because no party had requested it and because a total exclusion of all discharges through groundwater “would open a loophole allowing easy evasion of the [Act’s] basic purposes.”

In the end, the Court settled on the “functional equivalent” test and identified several factors which may be relevant to determining whether a particular discharge is the functional equivalent of one directly into navigable waters:

• transit time;
• distance traveled;
• the nature of the material through which the pollutant travels;
• the extent to which the pollutant is diluted or chemically changed as it travels;
• the amount of pollutant entering the navigable waters relative to the amount of the pollutant that leaves the point source;
• the manner by or area in which the pollutant enters the navigable waters; and
• the degree to which the pollution has maintained its specific identity at the point it enters the navigable water.

The first two factors, time and distance, will be the most important factors in most cases.

The problem with this new test is that it introduces a number of new ambiguities to replace the original ambiguity over whether discharges to groundwater required a CWA permit. The Court acknowledged these shortcomings: the list of factors is not exhaustive (“courts can provide guidance through decisions in individual cases”); the two factors which the Court said are most important will “not necessarily [be important in] every case;” and even when time and distance are important, there is only a sliding scale of the acceptable range (a permit is required somewhere between “[w]here a pipe ends a few feet from navigable waters” and “[i]f the pipe ends 50 miles from navigable waters and the pipe emits pollutants that travel with groundwater, mix with much other material, and end up in navigable waters only many years later”).

During a status conference in federal district court following the decision, the Maui wastewater facility declared its intent to proceed to discovery and prepare its case for trial in light of the Supreme Court’s ruling. Both parties will have an opportunity to submit additional briefs on discovery issues, which the district court will hear in a further status conference at the end of June.

In combination with the EPA’s newly-promulgated Navigable Waters Protection Rule revising the definition of “waters of the United States,” which takes effect on June 22, 2020, the Supreme Court’s decision marks a major shift in CWA permitting.

We will continue to monitor judicial and administrative developments under the CWA as courts and the EPA apply this new “functional equivalent” test. For any questions regarding this evolving area of the law, please reach out to the attorneys at Mackie Shea Durning, PC.
