 We recognize that cootrol must be on many firoots, iiwhiding ballast water management, cfaemical oontroi, predatoty fish 

 cootiol, and other mechanisms. Vessels must use ballast water for safety puiposes to provide adequate stability, trim, 

 piopulsica, maoeuverability, and hull stress coatroL Recognizing these constraints, the marine industry will do everything 

 within its power, (fwiwnt with safety and stability, to decrease the spiead of known unwanted ooD-indigeaous species. 

 The imroductioa of new species from outside the system is under the control of the U. S. and rajHMtian Coast Guards 

 through ballast water exchange regulations prior to entry into the syston. This plan deals with the control of the spread of 

 the European Ru£fe fixxn Western Lake Superior ports, in particular, Duhith/Supehor or other haibon where Ruffe 

 colonies are documented. 



FOR VESSELS DEPARTING LAKE SUPERIOR PORTS WESTON BALLAST DEMARCATION LINE: 



Operators of vessels pumping ballast water onboard in the above harbon, with ballast line intakes equipped with 

 screens fitted with holes larger dian Vi" in diameter, are restricted at all tines of the year in their pumping oat of 

 ballast water from these haifoors into the Great Lakes or their Comecting Channels or harbors. This ballast water 

 should be pumped out west of a ballast demarcation line between Ontooagon. Michigan and Grand Portage, 

 Minnesota. Ballast water from these haibors must not be pumped out within 5 miles of the south shore of Lake 

 Superior while west of the ballast demarcation line. Ballast exchange should take place in water at least 20 fethoms 

 (120 feet) deep. 



Opeiators of vessels pumping ballast water onboard in the above harbors, with ballast line intakes equipped with 

 screens fitted with holes '/>" in diameter or less, are restricted only during the period between May 15 and September 

 IS in their pumping out of ballast water from chese harbors into the Great Lakes or their Connecting Channels or 

 harbors. During this 4-montfa period, diese vessels should pump out the harbor ballast water west of a ballast 

 demarcation line between Ontonagon, Michigan and Grand Portage, Minnesota. Harbor ballast water must not be 

 pumped out within 5 miles of the south shore of Lake Superior while west of the ballast demarcation line. Ballast 

 exchange should take place in water at least 20 fethoms (120 feet) deep. 



If ballast exchange is not completed at die time the vessel reaches the demaicatiao line, exchange may onminue in 

 Lake Superior, but only in waters at least 40 &thoms (240 feet deep) and IS miles fiom shore. In all cases, exchange 

 must stop before prorwding east of 86" west 



FOR VESSELS DEPARTING LAKE SUPERIOR PORTS EASTOV BALLAST DEMARCATION LINE: 



4) Vessels departing Thunder Bay should limit pumping ballast ooboard as in paragiaphs 1) and 2) above. These 

 vessels may exchange ballast in Lake Superior, but only in waters at least 40 fethoms (240 feet deep) and 15 miles 

 from shore. In all cases, exchange must stop before proceeding east of 86° west 



TOR ALL VESSELS DEPARTING LAKE SUPERIOR PORTS: 



5) Operators of vessels pumping m ballast water from the above baibois and leaving the harbor with that water will 

 mamtam a record showing the amount of ballast water ralfiti the means of control, if any, and the location where the I 

 treated or untreated harbor ballast water was pumped out. 



6) The ballast water records will be available for review by U.S. or Canadian Coast Guard personnel. 



7) The above requirements will be waived for vessels which attest by means of a log entry that the harbor ballast waieri 

 fixxn the above harbors will not be pumped out wittun the Great Lakes/SL Lawrence Seaway System (at least ucnl I 

 reaching salt water). Masters of these vessels recognize that ballast water from the above harbors must .lot bei 

 pumped out in anv other tiesh or brackish water port and thus should exchange ballast ^vnfa salt water.
