scope:

This ER addresses shallow- and deep-draft navigation projects located in rivers, reservoirs, lakes, estuaries, and the coastal zone. Ongoing project-related reporting, inspection, and monitoring programs should continue. The MCNP program may be implemented as either a comprehensive detailed survey to verify postconstruction conditions on a one-time basis or a continuous (repetitive) collection of appropriate prototype data over an extended period. Generally, the continuous monitoring efforts will not exceed five years in length. The MCNP Program can only fund monitoring for completed projects operated and/or maintained by the CE. It is limited to funds available for project monitoring. Projects must be related to navigation, or mitigation for navigation projects, to be monitored by the MCNP Program. The availability of previously collected data will be a factor in the selection of projects for monitoring under the MCNP Program.

Purpose. This engineer regulation (ER) states the objective, outlines the scope, discusses funding, assigns responsibility, and establishes the procedures by which the Corps of Engineers (CE) evaluates planning, design, construction, and operation and maintenance performance of civil works navigation projects.

Applicability. This regulation applies to all USACE Commands with responsibility for civil works projects.
