Public Notices

A public notice is the primary method the Corps uses to advise interested parties of a proposed activity for which a Department of the Army permit is being sought. The Corps solicits comments and information to evaluate the probable impacts of the proposed activity on the public interest. Public notices are also used to inform the public about new or proposed regulations, policies, guidance, or permit procedures.

Public Notices issued by the Sacramento District are posted on this page and can be found on the Corps’ Regulatory Request System (RRS). Once a public notice is available on-line, an email notification is sent to individuals who signed up to receive our public notices.  Comments, which are due by the expiration date of the public notice, should be submitted through the RRS. Only comments submitted through the RRS, by email, or in hard copy format through a delivery service, such as the U.S. Postal Service, can be accepted. Hard copy comments must be submitted to the address listed in the public notice.

Special Public Notice: Applicability of the Clean Water Act 404(f)(1)(C) exemption for the construction or maintenance of irrigation ditches and the maintenance of drainage ditches within Colorado

Regulatory Division
Published March 25, 2021

SUBJECT: On July 24, 2020, the U.S. Army Corps of Engineers (Corps) and U.S. Environmental Protection Agency (EPA) issued a memorandum to the field regarding application of the exemptions under Section 404(f)(1)(C) of the CWA for the construction or maintenance of irrigation ditches and for the maintenance of drainage ditches. For purposes of implementing the ditch exemptions, the memo defines terms including “irrigation ditch” and “drainage ditch” and provides a framework for determining the applicability of the ditch exemptions and the recapture provision in CWA Section 404(f)(2). The memorandum provides a clear, consistent approach regarding the application of the exemptions, superseding prior national guidance.

DESCRIPTION: The fact sheet identifies the specifics relating to how this memorandum affects the Corps’ Regulatory Program in Colorado and where to find more information.
