Notices to Navigation Interests (NTNI)
The current NTNI website and process was introduced in 2015 as a way to provide centralized and standardized navigational information primarily about USACE projects to the industry and the public. Notices are published periodically as the need arises. A variety of information is provided within notices including:
- USACE work planned/in progress including maintenance dredging, lock maintenance, and work on jetties and breakwaters
- Deliberate modifications to channel dimensions, including reductions in maintained depths, or changes in other significant project features
- Section 10 permit work which may impact general navigation
- Change in USACE issued navigation regulations
- Special/temporary operating restrictions imposed by USACE
- Information for correction of USACE charts
- Advance notice of USACE chart revision publication of next edition
- Changes or corrections to National Ocean Service-charted features
Other government agencies also post notices, including the U.S. Coast Guard and the National Oceanic and Atmospheric Administration.
