On October 22, 2019, the EPA and the Corps published a final rule (Step One) to repeal the 2015 Rule defining “waters of the United States” and re-codify the regulatory text that existed prior to the 2015 Rule. The final Step One rule became effective on December 23, 2019. Read the final Step One rule.
On January 23, 2020, the EPA and the Corps finalized the Navigable Waters Protection Rule (Step Two) to redefine “waters of the United States” (WOTUS).The Step One rule was then replaced by the Navigable Waters Protection Rule when it was published in the Federal Register on April 21, 2020. The final rule will become effetive 60 days after the publication date. Factsheets on the Navigable Waters Protection Rule are available here.
Throughout the years and all of the legal challenges beginning in 2001 and earlier, the Association of State Wetland Managers has worked to stay abreast of potential changes in jurisdiction and practical application of the Clean Water Act in order to keep state and tribal wetland program managers prepared and equipped to navigate any regulatory changes or impacts to their programs.

Summaries of Significant Clean Water Act Court Decisions
United States v. Riverside Bayview Homes, 474 U.S. 121 (1985)
A developer challenged the government’s determination that groundwater fed wetlands, adjacent to Black Creek, a navigable waterway, in the Lake St. Clair area of Michigan, were “waters of the United States” (WOTUS). The Supreme Court, in a unanimous decision, held that adjacent wetlands, in this case the hydric soils and hydrophitic vegetation of which extended beyond the wetlands on the developer’s property, were WOTUS. This definition of WOTUS was broader than “navigable waters,” because “protection of aquatic ecosystems, Congress recognized, demanded broad federal authority to control pollution”. The court also noted that even wetlands that are not flooded by adjacent waters may still drain into those waters, serving to filter and purify water, as well as slowing the flow of surface runoff into lakes, rivers, and streams.
Solid Waste Agency of Northern Cook County v. US (SWANCC), 531 U.S. 159 (2001)
A landfill operator challenged the government’s determination that ponds in an abandoned sand and gravel pit site were jurisdictional based on use by migratory birds under the so-called ‘Migratory Bird Rule.’ The Supreme Court, in a 5 to 4 decision, held that isolated, non-navigable, intrastate waters used by migratory birds as habitat are not waters of the United States (WOTUS). The Government’s argument that the ‘Migratory Bird Rule” falls within Congress’ power to regulate intrastate activities that substantially affect interstate commerce, raises significant constitutional questions, yet there is nothing approaching a clear statement from Congress that it intended to reach abandoned sand and gravel pits. “The grant of authority of Congress under the Commerce Clause, though broad, is not unlimited.”
Rapanos v. United States, 547 S.Ct. 715 (2006)
A Michigan developer challenged the government’s enforcement action for placing fill in wetlands that were hydrologically connected by surface connection to tributaries of navigable waters. The four justice plurality decision, written by Justice Scalia, held that “waters of the United States” (WOTUS) includes only those relatively permanent, standing or continuously flowing bodies of water “forming geographic features” that are described in ordinary parlance as ‘streams, rivers and lakes, and does not include channels through which water flows intermittently or ephemerally, or channels that periodically provide drainage for rainfall. While four other justices wrote dissenting opinions, one justice, Justice Kennedy, wrote a concurring opinion, which has become the “the significant nexus” test. According to Justice Kennedy, wetlands possess the requisite nexus, and thus are navigable waters, “if the wetlands, either alone or in combination with similarly situated lands in the region, significantly affect the chemical, physical, and biological integrity of other covered waters more readily understood as navigable. Since 2006, Rapanos has and will continue to influence wetlands judicial decisions as well as agency rulemaking.
Sackett v. EPA, 132 S.Ct. 1367 (2012)
The Sacketts owned a residential site in Idaho that contained wetlands separated from Priest Lake by several lots containing permanent structures. The government determined that the wetlands were adjacent, jurisdictional wetlands. When the Sacketts filled the one half acre of wetlands, the EPA sent them a compliance order, and denied the Sacketts request for an administrative hearing. This was in accordance with a federal regulation at the time that a wetlands jurisdictional determination (JD) was not a “final agency action” entitled to an administrative hearing because no permit had been issued. The Supreme Court, in a rare unanimous decision, especially when it comes to wetlands, held to the contrary. The JD had all the hallmarks of “finality” under the Administrative Procedures Act (APA), and therefore the Sacketts could challenge the JD.
