scope:

This manual applies to all active and reserve afloat and ashore commands.

 a. For afloat commands, water monitoring requirements found in Chapter 1 do not apply under the following condition: Vessel is moored and receives shore water from an approved municipal source which maintains a free available chlorine residual. In addition, shore water must bypass the ship's water storage tank(s).

b. Ashore commands with CG-owned water systems, ? see section 2-H, are required to comply state or EPA monitoring and reporting requirements. Ashore commands who receive water from approved municipal treatment facilities are exempt from monitoring and reporting requirements if the water has a reliable disinfectant, e.g., chlorine, residual and is not further treated or stored. In addition to this Instruction, units must coordinate with their servicing Maintenance and Logistics Command, state regulating authority, and the Environmental Protection Agency to determine applicable regulations.

PURPOSE: To provide standards and public health information for Coast Guard personnel responsible for producing, storing, monitoring, and using potable water and wastewater systems at afloat and ashore units.
