 May 15, 2024 – Permit applications are now available in RRS! 

USACE is pleased to announce that the new national online application portal and management platform, known as the Regulatory Request System (RRS) now includes an electronic submission option for permit applications. This platform has been introduced to modernize our permit application process to address our users' expectations by providing a straightforward and transparent process for the submittal of permit requests.

RRS is a web-based platform currently in a beta version that enables users to submit pre-application meeting requests, jurisdictional determination requests, and now applications for individual and general permits. This new system aims to streamline the process, improve efficiency, and provide a more user-friendly experience for our applicants.     

At this time the RRS system does not accept the Idaho Joint Application Permit Form.  The Army Corps of Engineers (Corps), the Idaho Department of Water Resources (IDWR), and Idaho Department of Lands (IDL) has established a joint process for activities impacting jurisdictional waterways that require review and/or approval of both the Corps and the State of Idaho. The Stream Application Alteration Permit is the same application as the Walla Walla District Corps of Engineers 404 Joint Application. You only need to fill out the application once; you can send the same copy to all agencies as needed. 

We encourage applicants to continue to use the Idaho Joint Application for Permit in the interim, please visit Walla Walla District > Business With Us > Regulatory Division > Joint Application for Permit (army.mil) for information for applying for a permit.

18 January 2023 – Final Revised Definition of "Waters of the United States"

On December 30, 2022, the U.S. Environmental Protection Agency (EPA) and the U.S. Department of the Army (the agencies) announced the final "Revised Definition of 'Waters of the United States'" rule. On January 18, 2023, the rule was published in the Federal Register; the rule will be effective on March 20, 2023. The agencies developed this rule with consideration of the relevant provisions of the Clean Water Act and the statute as a whole, relevant Supreme Court case law, and the agencies’ technical expertise after more than 45 years of implementing the longstanding pre-2015 “waters of the United States” framework. This rule also considers the best available science and extensive public comment to establish a definition of “waters of the United States” that supports public health, environmental protection, agricultural activity, and economic growth. More information about the final rule is available at: https://www.epa.gov/wotus/revising-definition-waters-united-states.

 

 01 December 2022 – Release of the Interim Draft of the National Ordinary High Water Mark Field Delineation Manual for Rivers and Streams

The U.S. Army Corps of Engineers (USACE) and EPA (the Agencies) jointly announce the availability of the Interim Draft of the National Ordinary High Water Mark Field Delineation Manual for Rivers and Streams (National OHWM Manual) and its accompanying data sheet. The Interim Draft National OHWM Manual provides draft technical guidance for identifying and delineating the OHWM using a scientifically supported, rapid framework. The Agencies are requesting comments and feedback from the public and practitioners on the Interim Draft of the National OHWM Manual via the public notice linked below. Following the public comment period and additional field testing, comments and feedback received from the public and practitioners will be utilized to further refine the Interim Draft of the National OHWM Manual for clarity, consistency, and technical accuracy. The one-year testing and comment period ends on December 1, 2023. A final version of the National OHWM Manual is anticipated to be published during 2024.

During the period while the OHWM Manual is an interim draft, OHWM identification and/or delineation for official USACE Regulatory purposes should continue in accordance with the applicable OHWM definition in the Federal regulations, Regulatory Guidance Letter 05-05, and any applicable USACE district policies. However, USACE Regulatory staff are encouraged to test the Interim Draft of the National OHWM Manual and provide comments and feedback by emailing usace.ohwm@usace.army.mil.

 

27 April 2022 – Water Quality Certifications and USACE Permitting

On April 6, 2022, the U.S. Supreme Court issued a stay of the October 2021 order by the U.S. District Court for the Northern District of California that vacated EPA’s 2020 Clean Water Act Section 401 Certification Rule. The stay of the vacatur applies nationwide. Therefore, the CWA Section 401 certification process is once again governed by the CWA section 401 certification regulations promulgated by EPA in 2020. Districts will confer with certifying authorities regarding water quality certification decisions they issued on or after April 6, 2022 to determine whether they would like us to review those decisions under EPA’s 2020 Rule, or if they would like us to extend the reasonable period of time (when possible within the one year statutory limit) to allow the certifying authority to process the WQC request under EPA’s 2020 Rule. Permit actions or general permit verifications that were finalized prior to April 6, 2022 do not have to be revisited. Additional information regarding the stay can be found on EPA’s website at: https://www.epa.gov/cwa-401/qa-stay-2020-rule-vacatur

 

05 April 2022 – Army Corps of Engineers Announces the Release of Automated Wetland Determination Data Sheets (ADS)

The U.S. Army Corps of Engineers (USACE) announces the release of the ENG Forms 6116 (1-9), Automated Wetland Determination Data Sheet (ADS), and the associated “User Guide for Automated Wetland Determination Data Sheets.” These documents are available at the USACE Regulatory Headquarters website in both Portable Document Format (PDF) and Microsoft Excel (Excel) file formats. Practitioners should, at a minimum, utilize the PDF versions of the Office of Management and Budget approved forms to document the presence or absence of wetlands for the applications related to the administration of the Clean Water Act (CWA) and the Rivers and Harbors Act (RHA). The Excel-based ADS is an optional tool.  However, the PDF versions do not provide the automated features found in the Excel-based versions.

LINK TO ADS AND USER GUIDE: (https://www.usace.army.mil/Missions/Civil-Works/Regulatory-Program-and-Permits/reg_supp/).  (under “General Information”)

Wetland determination data forms are used to document the presence or absence of wetlands, as  outlined in the Regional Supplements to the Corps of Engineers Wetland Delineation Manual (Regional Supplements). The wetland determination data forms included in the Regional Supplements were initially published as PDF files which were intended to be manually completed by hand. A subsequent collaboration between the USACE Detroit District and the U.S. Army Engineer Research and Development Center’s Wetlands Regulatory Assistance Program resulted in the development of an automated, Excel-based ADS for each of the 10 Regional Supplements and an associated user guide to aid in ADS application. 

The Excel-based ADS increases technical accuracy by reducing errors, and increases efficiency by automatically populating many of the field indicators of wetland hydrology, hydrophytic vegetation, and hydric soils. The ADS incorporates or includes the following:

  • Similar layout as the Regional Supplement wetland determination data forms,
  • Application of the most up-to-date plant species wetland indicator status ratings from the National Wetland Plant List (currently the 2020 National Wetland Plant List, version 3.5),
  • Automated calculation of hydrophytic vegetation indicators,
  • Automated interpretation of most hydric soil indicators and certain wetland hydrology indicators,
  • Automated features prompting users to complete or review required information,
  • Exportable to PDF or other electronic format, and the ability to print formatted hard copies, and
  • Application of the most up-to-date field indicators of hydric soils (currently version 8.2).

The ADS is utilized to document the presence or absence of wetlands. A wetland delineation alone is not a determination of the jurisdictional status of an area under the CWA or the RHA. Additional information and analysis beyond wetland delineation protocols is required to determine if an area is subject to CWA and/or RHA jurisdiction. The ADS do not provide any new guidance regarding wetland identification or delineation, or change USACE Regulatory program policies. Rather, the ADS provide a tool to help improve the efficiency and accuracy of field data collection and reporting. Users remain responsible for ensuring that wetland delineation data entry and analysis are accurate when utilizing the ADS for CWA and RHA applications.

For additional information on or application of the ADS, or to submit error reports, please contact autodatasheet@usace.army.mil.

 05 January 2022 – Navigable Waters Protection Rule Vacatur

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 (“NWPR”) nationwide and are interpreting “waters of the United States” consistent with the pre-2015 regulatory regime until further notice. The agencies are 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.

On November 18, 2021, the agencies announced the signing of a proposed rule to revise the definition of “waters of the United States.” This proposal marks a key milestone in the regulatory process announced in June 2021. The agencies propose to put back into place the pre-2015 definition of “waters of the United States,” updated to reflect consideration of Supreme Court decisions. This familiar approach would support a stable implementation of “waters of the United States” while the agencies continue to consult with states, tribes, local governments, and a broad array of stakeholders in both the current implementation and future regulatory actions.

A durable definition of “waters of the United States” is essential to ensuring clean and safe water in all communities—supporting human health, animal habitat, agriculture, watersheds, flood management, local economies, and industry. This rulemaking process follows a review conducted by the agencies as directed by the January 20, 2021 Executive Order 13990 on “Protecting Public Health and the Environment and Restoring Science to Tackle the Climate Crisis.”

Further details about the agencies’ plans, including information regarding the upcoming public meetings and proposed rule docket, can be found here.

An approved jurisdictional determination (“AJD”) is a document provided by the Corps stating the presence or absence of “waters of the United States” on a parcel or a written statement and map identifying the limits of “waters of the United States” on a parcel. See 33 C.F.R. § 331.2. Under existing Corps’ policy, AJDs are generally valid for five years unless new information warrants revision prior to the expiration date. See U.S. Army Corps of Engineers, Regulatory Guidance Letter No. 05–02, § 1(a), p. 1 (June 2005) (Regulatory Guidance Letter (RGL) 05–02). 
 

As a general matter, the agencies’ actions are governed by the definition of “waters of the United States” that is in effect at the time the Corps completes an AJD, not by the date of the request for an AJD. AJDs completed prior to the court’s decision and not associated with a permit action (also known as “stand-alone” AJDs under RGL 16-01) will not be reopened until their expiration date, unless one of the criteria for revision is met under RGL 05-02. A NWPR AJD could also be reopened if the recipient of such an AJD requests a new AJD be provided pursuant to the pre-2015 regulatory regime. In that case, the Corps will honor such request recognizing that if the recipient of a NWPR AJD intends to discharge into waters identified as non-jurisdictional under the NWPR but which may be jurisdictional under the pre-2015 regulatory regime, such recipient may want to discuss their options with the Corps. AJD requests pending on, or received after, the Arizona court’s vacatur decision will be completed consistent with the pre-2015 regulatory regime.
 

As the agencies’ actions are governed by the regulatory definition at the time of the action, permit decisions made prior to the court’s decision that relied on a NWPR AJD will not be reconsidered in response to the NWPR vacatur. Permit decisions may be modified, suspended, or revoked per 33 C.F.R. § 325.7 where the regulatory criteria are met. The Corps will not rely on an AJD issued under the NWPR (a “NWPR AJD”) in making a new permit decision. The Corps will make new permit decisions pursuant to the currently applicable regulatory regime (i.e., the pre-2015 regulatory regime). Therefore, for any currently pending permit action that relies on a NWPR AJD, or for any future permit application received that intends to rely on a NWPR AJD for purposes of permit processing, the Corps will discuss with the applicant, as detailed in RGL 16-01, whether the applicant would like to receive a new AJD completed under the pre-2015 regulatory regime to continue their permit processing or whether the applicant would like to proceed in reliance on a preliminary JD or no JD whatsoever.

 02 December 2021 – Water Quality Certifications and Corps Permitting

On October 21, 2021 the U.S. District Court for the Northern District of California issued an order vacating and remanding the Environmental Protection Agency’s 2020 regulations implementing Section 401 of the Clean Water Act.  On November 18, 2021, after a temporary pause on permit decisions reliant on a Section 401 water quality certification or waiver completed under the vacated regulations, Corps districts resumed making decisions on all permit applications and requests for nationwide permit verifications.  As part of that decision making process, districts will coordinate with certifying authorities on water quality certifications that are potentially impacted by the vacatur order.

Additional information regarding the vacatur can be found on EPA’s website at: https://www.epa.gov/cwa-401/2020-clean-water-act-section-401-certification-rule  

 18 November 2021 – EPA, Army Announce Signing of Proposed Rule to Revise the Definition of Waters of the United States

On 18 November 2021, the U.S. Environmental Protection Agency and the Department of the Army (“the agencies”) announced the signing of a proposed rule to revise the definition of “waters of the United States.” This proposal marks a key milestone in the regulatory process announced in June of 2021. The agencies propose to put back into place the pre-2015 definition of “waters of the United States,” updated to reflect consideration of Supreme Court decisions. This familiar approach to “waters of the United States” would support a stable implementation of “waters of the United States” while the agencies continue to consult with states, Tribes, local governments, and a broad array of stakeholders in both the implementation of WOTUS and future regulatory actions.

In developing the proposed rule, EPA and the Army reviewed and considered the extensive feedback and recommendations the agencies received from states, tribes, local governments, and stakeholders throughout consultations and pre-proposal meetings and webinars.

The agencies’ press release for the 18 November 2021 announcement is available at https://www.epa.gov/wotus/revising-definition-waters-united-states .

 17 November 2021 – Rescission of the 30 June 2020 NWPR Memo, “EPA and U.S. Army Corps of Engineers Process for Elevating and Coordinating Specific Draft Determinations under the Clean Water Act

After careful consideration, the U.S. Environmental Protection Agency and the Department of the Army have rescinded the memorandum “U.S. Environmental Protection Agency (EPA) and U.S. Army Corps of Engineers (Corps) Process for Elevating and Coordinating Specific Draft Determinations under the Clean Water Act (CWA),” signed by EPA on June 26, 2020 and Army on June 30, 2020. The memorandum established a process by which the Corps and EPA (together, the agencies) intended to elevate to their headquarters for coordination certain case-specific and stand-alone CWA determinations under paragraph (a)(1) of the Navigable Waters Protection Rule (NWPR). The NWPR did not change the definition of traditional navigable waters and retained the agencies’ longstanding “guidance on determining whether a water is a ‘traditional navigable water’ for purposes of the Rapanos Guidance, the Clean Water Act (CWA), and the agencies’ CWA implementing regulations.” However, by establishing new procedures for one category of traditional navigable waters, the 2020 elevation memorandum created an unnecessary extra step for making traditional navigable waters determinations that the agencies have been making for many years. Therefore, the agencies are rescinding that memorandum, and retaining their legal memorandum on traditional navigable waters, which has remained unchanged since 2007. The legal memorandum, “Legal Definition of ‘Traditional Navigable Waters,’” can be found at https://www.epa.gov/wotus/legal-definition-traditional-navigable-waters.”

 02 November 2021 – Final 2020 National Wetland Plant List

The U.S. Army Corps of Engineers, as part of an interagency effort with the U.S. Environmental Protection Agency, the U.S. Fish and Wildlife Service, and the U.S. Department of Agriculture Natural Resources Conservation Service, is announcing the availability of the final 2020 National Wetland Plant List (NWPL). The Federal Register Notice for the 2020 NWPL update can be found here: https://www.federalregister.gov/documents/2021/11/02/2021-23891/national-wetland-plant-list The NWPL provides plant species wetland indicator status ratings, which are used in determining whether the hydrophytic vegetation factor is met when conducting wetland delineations under the Clean Water Act and wetland determinations under the Wetland Conservation Provisions of the Food Security Act. Other applications of the NWPL include wetland restoration, establishment, and enhancement projects. The list is effective as of 2 November 2021 and will be used in any wetland delineations performed after this date. Completed wetland delineation/determination forms should reference the version of the NWPL used to complete the form.  The final NWPL is available at https://wetland-plants.sec.usace.army.mil/ (preferred browsers are Chrome and Firefox).

 13 January 2021 – Army Corps of Engineers Publishes 2021 Nationwide Permits

USACE announce today the publication in the Federal Register of the 2021 Nationwide Permits (NWPs) at https://www.federalregister.gov/documents/2021/01/13/2021-00102/reissuance-and-modification-of-nationwide-permits.  The 12 reissued and four new 2021 NWPs in the rule are necessary for work in streams, wetlands and other waters of the United States under Section 404 of the Clean Water Act and Section 10 of the Rivers and Harbors Act of 1899.  These 16 NWPs will go into effect on March 15, 2021 and will expire on March 14, 2026.  The 40 existing NWPs that were not reissued or modified by the January 13, 2021, final rule remain in effect. More information on NWPs can be found at https://www.usace.army.mil/Missions/Civil-Works/Regulatory-Program-and-Permits/National-Notices-and-Program-Initiatives/.

 28 January 2020 – NRCS and Army Rescind 2005 Joint Memorandum

The Natural Resources Conservation Service (NRCS) and the Deputy Assistant Secretary of the Army have provided written notice to rescind the 2005 joint memorandum titled "Guidance on Conduction Wetland Determinations for the Food Security Act of 1985 and Section 404 of the Clean Water Act".  This rescission is effective immediately. This rescission does not alter the roles or responsibilities of the Agencies under their respective statutory and regulatory authorities. The Agencies will continue their practice of informing landowners that wetland delineations (performed by the Corps) and determinations (performed by the NRCS) may not be valid for FSA or CWA requirements, respectively.  The Agencies intend to issue new guidance on this topic in the near future.

 18 June 2019  Special Public Notice: Walla Walla Regulatory Wetland Delineation Guidance

 25 February 2019 – Army Issues New Regulatory Guidance for Mitigation Banks – Improving Efficiency and Consistency in the Corps Regulatory Program

On February 22, 2019, the U.S. Army Corps of Engineers (Corps) issued Regulatory Guidance Letter (RGL) 19-01 “Mitigation Bank Credit Release Schedules and Equivalency in Mitigation Bank and In-Lieu Fee Program Service Areas.” Developed in collaboration with the U.S. Environmental Protection Agency, RGL 19-01 provides guidance to District Commanders on two issues relating to that authority: credit release schedules for mitigation banks and consistency in establishing service areas for mitigation banks and in-lieu fee programs.


In 2015, the Corps conducted an analysis of the implementation of the 2008 Mitigation Rule. The analysis compared the processing timeframes for Department of the Army permits between the use mitigation bank or in-lieu fee credits and permittee-responsible mitigation to meet compensatory mitigation requirements. Permit processing timeframes were reduced by approximately 50 percent with the use of mitigation bank or in lieu fee credits.


Consistent with flexibility within the 2008 Mitigation Rule, RGL 19-01 will provide a substantial benefit to the Nation by facilitating the release of more credits available for sale to permittees shortly after successful construction of a mitigation bank. The Army anticipates that allowing for additional credits for sale will result in mitigation credits be sold at a more competitive, fair and comparable prices.


“Having more credits available for sale to permittees can allow for even more reduced permitting timeframes for the important infrastructure, energy, and other administration priority activities,” said R.D. James, Assistant Secretary of the Army for Civil Works “Homebuilders and many others who need authorization from the Corps for their proposed activities will also benefit from increase in available mitigation credits.”


The credit release is contingent on the bank sponsor successfully constructing the mitigation bank in accordance with the Corps approved mitigation plan and providing sufficient financial assurances that the bank will meet the approved ecological performance standards.


This guidance will benefit the mitigation bankers businesses, the permittees, as well as the aquatic resources. The Army anticipates that improved guidance in releasing mitigation credits will encourage more investment in mitigation banks, thereby improving the quantity and quality of aquatic habitat being restored Nation-wide.


In addition to addressing the credit release schedules for mitigation banks, the RGL also addresses service areas for mitigation banks and in-lieu fee programs. In 2004, Congress mandated that the Corps in developing the 2008 Mitigation Rule to "apply equivalent standards and criteria to each type [on-site, off-site, and in-lieu fee mitigation and mitigation banking] of compensatory mitigation". Therefore, the guidance makes clear that with each District, the Corps should ensure that the same criteria are used to establish similar service areas for mitigation banks and in-lieu fee programs.

Regulatory Program Misson

Water is one of our nation’s most valuable resources. It is becoming increasingly important that we protect the quality of our inland waters and wetlands for the use and benefit of future generations.

The Department of the Army's Regulatory Program is one of the oldest in the federal government. Initially, it served a simple purpose: to protect and maintain the navigable capacity of the nation's waters. Changing public needs, evolving policy, court decisions and new statutory mandates have changed several aspects of the program including its breadth, complexity and authority.

The U.S. Army Corps of Engineers, through the Regulatory Program, administers and enforces Section 10 of the Rivers and Harbors Act of 1899 (RHA) and Section 404 of the Clean Water Act (CWA). Under RHA Section 10, a permit is required for work or structures in, over or under navigable waters of the United States. Under CWA Section 404, a permit is required for the discharge of dredged or fill material into waters of the United States. Many waterbodies and wetlands in the nation are waters of the United States and are subject to the Corps' regulatory authority.

The Regulatory Program is committed to protecting the Nation's aquatic resources and navigation capacity, while allowing reasonable development through fair, flexible and balanced permit decisions. The Corps evaluates permit applications for essentially all construction activities that occur in the Nation's waters, including wetlands.

Program Overview

The Walla Walla District, Corps of Engineers is responsible for administering the Regulatory Program in the State of Idaho. The Regulatory office processes permit applications for work that occurs in “waters of the United States” that are regulated by the Corps.

Examples of work activities that require a permit include, but are not limited to:

  • Dredging of waterways
  • Bank stabilization
  • Construction of piers, docks, marinas, fleeting areas, boat ramps, roads
  • Residential and commercial developments
  • Utility lines
  • Mining activities

Our Goals

The Walla Walla District Regulatory Program strives reach the goals of the mission:

1.  To provide protection to the nation’s aquatic environment, including wetlands.

2.  To enhance the efficiency of the administration of the regulatory program.

3.  To ensure that the Corps provides the public with fair and reasonable decisions.
