RRS Public Notice module - Monday, January 6, 2025

6 January 2025
Public Notices Module Now Available
Enhances RRS Functionality!

The U.S. Army Corps of Engineers (USACE) is excited to announce the launch of the Public Notice module on the Regulatory Request System (RRS). Released in January 2025, this new feature allows users nationwide to search, review, and comment on projects being reviewed by the Regulatory Program, significantly enhancing transparency, accessibility, and efficiency. The Public Notice module provides access to Regulatory projects requiring a standard permit or when public notices are issued to develop Mitigation Banks, In-lieu Fee Programs or to issue/reissue a Regional or Programmatic Permit or Section 404 Letter of Permission.  It organizes notices by state and district, which can be viewed in a table format or on an interactive map. Users can easily search for notices by project name or address and submit comments directly through the platform, streamlining public engagement and reinforcing USACE's commitment to improving transparency and the permitting process.

The RRS is a web-based platform, currently in its beta version, designed to simplify the permitting process and enhance user experience. In addition to the new Public Notice Module, RRS enables users to submit permit applications, request jurisdictional determinations, and schedule pre-application meetings, all through a user-friendly interface.

We encourage you to explore the Regulatory Request System and its new features by visiting rrs.usace.army.mil. For additional information or to provide feedback, please contact us at rrs@usace.army.mil

Notice of Availability of the Regional Streamflow Duration Assessment Methods for the Arid West, Western Mountain, and Great Plains

Joint Public Notice


Notice of Availability of the Regional Streamflow Duration Assessment Methods for the Arid West, Western Mountain, and Great Plains

The U.S. Army Corps of Engineers (Corps) Albuquerque, Chicago, Detroit, Fort Worth, Galveston, Kansas City, Los Angeles, Omaha, Rock Island, Sacramento, San Francisco, St. Louis, St. Paul, and Tulsa Districts, and the U.S. Environmental Protection Agency (EPA), Regions 5, 6, 7, 8, and 9 jointly announce the availability of the Regional Streamflow Duration Assessment Methods (Regional SDAMs) for the Arid West, Western Mountains and Great Plains (October 8th, 2024). The methods are rapid assessment tools to help distinguish between ephemeral, intermittent, and perennial streamflow at the reach scale for the Arid West, Western Mountains and Great Plains regions.

These Regional SDAMs were developed for use in all or part of the states of Arizona,

California, Colorado, Illinois, Iowa, Kansas, Michigan, Minnesota, Missouri, Montana, Nebraska, Nevada, New Mexico, North Dakota, Oklahoma, South Dakota, Texas, Utah, Wisconsin, and Wyoming by the Corps and the EPA (Figure 1). These methods result from a literature review and multi-year field study conducted at nearly 700 stream reaches across the range of hydrologic landscapes of the Arid West, Western Mountains and Great Plains. Developed through statistical analyses of the field data, the Regional SDAMs provide a data-driven approach using reliable indicators to determine streamflow duration class at the reach scale. The agencies are making these final Regional SDAMs available for public use.  This follows completion of a more than one year preliminary implementation and comment period on beta methods to inform development of the final Regional SDAMs.

The Regional SDAMs for the Arid West, Western Mountains and Great Plains can be applied whenever there is uncertainty regarding streamflow duration class and a rapid evaluation method is desired. The methods provide a scientifically supported, rapid assessment framework to support best professional judgment in a consistent, robust, repeatable, and defensible way. The classification outcome resulting from application of the methods may inform a range of activities where information on streamflow duration class can improve ecological assessment, management, and decision-making. The Regional SDAMs were developed specifically from data collected in the Arid West, Western Mountains and Great Plains.

Practitioners such as stream ecologists, aquatic ecologists, hydrologists, and wetland scientists are encouraged to utilize the Regional SDAMs. All materials and tools necessary to understand and support application of the Regional SDAMs can be found at: https://www.epa.gov/streamflow-duration-assessment.
