Denver Regulatory Office

The Department of the Army Regulatory Program is one of the oldest in the Federal Government. Initially it served a fairly simple, straightforward purpose: to protect and maintain the navigable capacity of the nation's waters. Time, changing public needs, evolving policy, case law and new statutory mandates have changed the complexion of the program, adding to its breadth, complexity and authority.

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

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

U.S. ARMY CORPS OF ENGINEERS, OMAHA DISTRICT, REGULATORY BRANCH

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 and 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 new 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.     

All six states in the Omaha District, which includes the northeastern quarter of Colorado, Nebraska, Montana, North Dakota, South Dakota, and Wyoming, are accepting RRS electronic submissions. Please note that in the state of Montana, the RRS joint permit application (JPA) process will not be available on May 15th.  The Montana Regulatory Offices will be flexible with incoming applications submitted in the RRS and continue to coordinate with state and federal counterparts to minimize the burden on applicants. The external JPA form for Montana’s resources is still available online; for further information regarding this JPA, please visit: https://dnrc.mt.gov/Licenses-and-Permits/Stream-Permitting/.

We believe that RRS will not only benefit our users by simplifying the application process but will also enhance our ability to effectively manage and review permit requests. We are confident that this modernization initiative will lead to improved customer satisfaction and greater overall efficiency within our Regulatory Program.

We encourage users to explore and utilize the new Regulatory Request System to take advantage of its benefits and features. Visit rrs.usace.army.mil today!

The U.S. Army Corps of Engineers, Omaha District has published in the federal register the Draft Environmental Impact Statement and conceptual mitigation plan for the Halligan Water Supply Project, a water supply project located in Larimer County, Colorado, proposed by the City of Fort Collins Utilities.  

The Corps is evaluating an application and conceptual mitigation plan from Fort Collins for a Department of the Army permit for the Halligan Project and prepared the Draft EIS in accordance with the National Environmental Policy Act to provide decision-makers and the public with information pertaining to the Halligan Project and disclose environmental impacts of the alternatives.  It also provides information for local and state agencies having jurisdictional responsibility for affected resources.  The U.S. Environmental Protection Agency Region VIII, U.S. Fish and Wildlife Service, Bureau of Land Management, Colorado Department of Natural Resources, Colorado Department of Public Health and Environment, and Larimer County participated as cooperating agencies in the development of the Draft EIS.  The Corps is neither a proponent nor an opponent of the proposed project.  

Fort Collins proposes to enlarge the existing Halligan Reservoir located about 25 miles northwest of Fort Collins on the North Fork of the Poudre River in Larimer County, Colorado.  Fort Collins proposes to raise Halligan Dam by 25.4 feet to enlarge Halligan Reservoir from its current capacity of 6,400 acre-feet to approximately 14,525 acre-feet to provide about 7,900 acre-feet of additional annual firm yield to meet Fort Collins’ projected 2065 municipal and industrial water demands.  The existing reservoir surface area is approximately 253 acres; the proposed enlargement would result in a surface area of approximately 386 acres.

Halligan Dam is a concrete arch dam built more than 100 years ago and will require rehabilitation in the near future to address safety risks.  These safety risks would be addressed by Fort Collins under their proposed action during enlargement of the dam.  Under the project alternatives, ownership of the dam and responsibility for rehabilitation would revert to the North Poudre Irrigation Company.

Under Fort Collins’ proposed action, Halligan Reservoir would continue to be filled with direct flows from the North Fork.  Releases would be made to the North Fork downstream of the dam and would flow through Seaman Reservoir to the confluence with the Cache la Poudre River.  From there, water would be exchanged up to Fort Collins’ intake or to the Monroe Canal intake and delivered to Fort Collins’ water treatment facility through the Pleasant Valley Pipeline.  

Under the proposed action, Fort Collins would maintain a minimum flow of five cubic feet per second in the North Fork from May 1 to September 30, a minimum flow of three cubic feet per second the remainder of the year, and forego all diversions to the enlarged Halligan Reservoir for the three days that coincide with the forecasted peak runoff flow event for the North Fork.

The Draft EIS also evaluates the effects of several alternatives to Fort Collins’ proposed action, including the No-Action Alternative, the Expanded Glade Alternative, the Gravel Pits Alternative, and the Agricultural Reservoirs Alternative.

The Corps’ decision on whether or not to issue a permit will be based on an evaluation of the probable impacts, including cumulative impacts, of the proposed project and its alternatives on the public interest.  The decision will reflect the national concern for both protection and use of important resources.  The benefits that may reasonably be expected to accrue from the proposal must be balanced against the reasonably foreseeable detriments.  All factors that may be relevant to the proposal will be considered including the cumulative effects thereof; among those are conservation, economics, aesthetics, wetlands, fish and wildlife values, flood hazards, floodplain values, land use, navigation, shoreline erosion and accretion, recreation, water supply and conservation, energy needs, safety, food and fiber production, mineral needs, considerations of property ownership and, in general, the needs and welfare of the people.  

The Draft EIS and conceptual mitigation plan are available for review on our website at:  http://www.nwo.usace.army.mil/Missions/Regulatory-Program/Colorado/EIS-Halligan

Printed copies of the Draft EIS are available for review at the following libraries and offices:

  • U.S. Army Corps of Engineers, Denver Regulatory Office, 9307 South Wadsworth Boulevard, Littleton, Colorado 80128

The Corps is soliciting written comments on the Draft EIS and conceptual mitigation planfrom the public; federal, state, and local agencies and officials; Native American Tribes; and other interested parties.  

On January 13, 2020, the Corps is holding a public hearing regarding the Department of the Army Permit application and Draft EIS for the Halligan Project.

Collapse All Expand All
 The Denver Regulatory Office of the U.S. Army Corps of Engineers' Omaha District has been working to be more responsive to the needs of the public. For the Regulatory Program, we know there is great interest in having us accept information associated with aquatic resource delineation verifications, permit applications, and other requests in a digital format, instead of paper. To that end, we have created a process for the public to submit their request electronically. This new process is easy to access, ensures timely delivery, and comports with Army and Department of Defense (DoD) requirements.

Effective immediately, we are asking that all new requests be submitted in digital form, which will eliminate any need to send a paper copy.

If you are submitting information associated with a new request, such as a permit application or request to verify an aquatic resources delineation, please submit it to DenverRegulatoryMailbox@usace.army.mil for initial in-processing. (NOTE: Emails including attachments cannot exceed 40Mb).

If you require assistance with an active request, we encourage you to send digital files directly to the project manager assigned to the action. If you do not know who is assigned to your action, please send your request to our general email box.

We will continue to accept paper copies of your requests if you are unable to submit them electronically.

We ask the public to submit their requests for jurisdictional determinations, permit applications, and other associated documents in digital form. This will eliminate the requirement for the public to send documents in paper form to the Corps and for the Corps to save those documents in paper form.

Contents of requests:

  1. The preferred document file format is .pdf. We will also accept Word documents in .docx format.
  2. The Aquatic Resource/Consolidated Upload Excel spreadsheet must be submitted in .xlsm spreadsheet format.
  3. If transmitting via email, include all information as email attachments, and avoid transmitting information in the body of the email.
  4. All documents (aquatic resource delineations, permit applications, endangered species biological assessment, historic properties reports, etc.) must be submitted as separate files. DO NOT combine all documents into one Adobe PDF or Word document file.
  5. Name files based on their content. Please do not use company project numbers or acronyms as the sole basis for the file name(s).
  6. Reduce file sizes to the maximum extent possible.

Submitting requests:

There are multiple options for submitting your request to the Corps (in order of preference):

  1. Submit via email. Our preferred method of electronic file submittal is via email.
    • Initial requests that have not been assigned a project manager and Corps project number should be sent to the Corps general email inbox: DenverRegulatoryMailbox@usace.army.mil
      • NOTE: Add to the Email Subject line the name of the applicant, name of the project, and name of the county in which the project is proposed.
    • Once a project has been assigned, documents should be emailed directly to the Corps Project Manager
      • NOTE: Add to the Email Subject line the Corps project number, name of the applicant, name of the project, and name of the county in which the project is proposed.
    • The Corps file limit is 40 MB for individual emails.  If your email would exceed 40MB, please request an upload link or use one of the methods below.
  2. Send a short cover letter and CD with all required information to the Denver Regulatory Office at 9307 South Wadsworth Boulevard, Littleton, Colorado 80128-6901. DO NOT SEND A USB STICK. The Corps cannot connect USB sticks to our computers.
