The U.S. Coast Guard announced Tuesday the acceptance of nine ballast water treatment systems as Alternate Management Systems (AMS) in compliance with the service’s March 2012 final rule for Standards for Living Organisms in Ships’ Ballast Water Discharged in U.S. waters.

AMS acceptance by the Coast Guard is a temporary designation given to a ballast water treatment system approved by a foreign administration. Vessel operators may use an AMS to manage their ballast water discharges in lieu of ballast water exchange, while the treatment system undergoes approval testing to Coast Guard standards.

An AMS may be used to meet the Coast Guard ballast water treatment requirements for up to five years after the ship’s ballast water discharge standard compliance date specified in the final rule. This five-year timeframe allows for the completion of required land-based and shipboard testing.

“With these AMS acceptances, we move into a new era of aquatic invasive species prevention and control,” said Coast Guard Rear Adm. Joseph A. Servidio, Assistant Commandant for Prevention Policy. “Compared with the existing requirement for mid-ocean ballast water exchange, these technological solutions reduce the ballast water exchange safety concerns for mariners and provide greater protection for the marine environment.”

“This is an important first step in making Coast Guard and foreign approved ballast water treatment systems available for the global shipping industry,” said Servidio. “The Coast Guard AMS program will allow ship owners and operators to install a ballast water treatment system and use it in U.S. waters while it undergoes approval testing.”

The Coast Guard continues to review applications for AMS acceptance and will announce further determinations.
