The Regulatory Branch's jurisdiction is subject to the River and Harbors Act and the Clean Water Act. Section 9 & 10 of the Rivers and Harbors Act of 1899 includes all navigable waters. This includes the territorial seas and those waters of the United States that are subject to the ebb and flow of the tide shoreward to the mean high water mark, and/or are presently used or have been used in the past, or may be susceptible to use to transport interstate or foreign commerce.
Section 404 of the Clean Water Act regulates discharges of dredged/fill material into waters of the United States. "Waters of the United States" is broadly defined to include waters whose alteration could or does influence interstate and international commerce. These waters include navigable waters, interstate waters, intrastate lakes, rivers, streams (including intermittent streams), mud flats, sand flats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds. This section 404 jurisdiction is defined as encompassing Section 10 waters plus their tributaries, adjacent wetlands and isolated waters. Final authority regarding Clean Water Act jurisdiction remains with the Environmental Protection Agency.
A Jurisdictional Determination (JD) is the procedure of identifying and locating jurisdictional waters of the United States regulated by the Corps of Engineers under Section 404 of the Clean Water Act and Section 10 of the Rivers & Harbors Act of 1899, and is commonly referred to as the “JD process”, a “wetland determination” or “delineation”. This process is essential when investigating, planning, designing, or submitting an application for a permit from the Corps to determine if the proposed activity will impact jurisdictional waters of the United States.
The Corps receives thousands of requests each year to perform JDs. Due to limited staff and resources, response time can be several months or longer. To expedite the JD process, we encourage applicants (commercial or private) to use a consultant to conduct wetland delineations whenever possible, especially for project areas greater than 5 acres. The consultant will delineate the extent of wetlands and other waters of the United States within the project area. The consultant should then submit the delineation report to the Corps for concurrence. Once a JD is completed for the project area, a determination of permit requirements can be made at that time.
To request a Jurisdictional Determination prior to submitting a permit application, please include a letter which addresses the information needed to complete an Approved Jurisdictional Determination. In most cases, a Preliminary Jurisdictional Determination is the most efficient type of JD for a given site. Preliminary JDs are non-binding and advisory in nature and cannot be appealed, while an Approved JD is appealable.
9 June 2021 - EPA, Army Announce Intent to Revise Definition of Waters of the United States
The Environmental Protection Agency and Department of the Army have announced their intent to revise the definition of “waters of the United States” (WOTUS), to better protect our nation’s vital water resources that support public health, environmental protection, agricultural activity, and economic growth. The EPA/Army press release can be accessed here: https://www.epa.gov/newsreleases/epa-army-announce-intent-revise-definition-wotus.
The agencies’ new regulatory effort will be guided by the following considerations: - Protecting water resources and our communities consistent with the Clean Water Act.
- The latest science and the effects of climate change on our waters.
- Emphasizing a rule with a practical implementation approach for state and Tribal partners.
- Reflecting the experience of and input received from landowners, the agricultural community that fuels and feeds the world, states, Tribes, local governments, community organizations, environmental groups, and disadvantaged communities with environmental justice concerns.
The agencies are committed to meaningful stakeholder engagement to ensure that a revised definition of waters of the United States considers essential clean water protections, as well as how the use of water supports key economic sectors. Further details of the agencies’ plans, including opportunity for public participation, will be conveyed in a forthcoming action.

30 July 2021 – EPA and Army Announce Next Steps for Crafting Enduring Definition of Waters of the United States
The Environmental Protection Agency (EPA) and the Department of the Army (Army) have announced plans for upcoming community engagements to inform their efforts to revise the definition of “waters of the United States” (WOTUS). EPA and Army have stated a commitment to developing a reasonable, effective, and durable definition of WOTUS that protects public health, the environment, and downstream communities while supporting economic opportunity, agriculture, and other industries.
EPA and Army are announcing a series of engagement opportunities, including an opportunity for stakeholders and the public to provide written recommendations and a series of public meetings in August to hear perspectives on the rulemaking.
The full announcement can be found here: https://www.epa.gov/newsreleases/epa-and-army-announce-next-steps-crafting-enduring-definition-waters-united-states.

3 September 2021 – Current Implementation of Waters of the United States
The Environmental Protection Agency and U.S. Army Corps of Engineers (the agencies) are in receipt of the U.S. District Court for the District of Arizona’s August 30, 2021, order vacating and remanding the Navigable Waters Protection Rule in the case of Pascua Yaqui Tribe v. U.S. Environmental Protection Agency. In light of this order, the agencies have halted implementation of the Navigable Waters Protection Rule and are interpreting “waters of the United States” consistent with the pre-2015 regulatory regime until further notice. The agencies continue to review the order and consider next steps. This includes working expeditiously to move forward with the rulemakings announced on June 9, 2021, in order to better protect our nation’s vital water resources that support public health, environmental protection, agricultural activity, and economic growth. The agencies remain committed to crafting a durable definition of “waters of the United States” that is informed by diverse perspectives and based on an inclusive foundation.
