Purpose.

This manual provides guidance and requirements for the selection, design, installation, operation, and maintenance of CPS for navigation lock gates and other U.S. Army Corps of Engineers (USACE) CW hydraulic steel structures (HSS). It may also be applicable to other types of structures and components depending on the specific application. This manual also discusses possible solutions to some of the problems with CPS that may be encountered at existing projects. For all Corrosion Prevention and Control (CPC) activities on HSS projects, it is critical to ensure compliance with this manual and other corrosion prevention criteria documents referenced below. This is to ensure that corrosion prevention activities, including selection and implementation of protective coatings, materials, and CPS, remain consistent across all USACE organizations.
