		These regulations also require vessels to maintain a ballast water management plan that is specific for that vessel and assigns responsibility to the master or appropriate official to understand and execute the ballast water management strategy for that vessel.
		Ballast water discharged from ships is one of the largest pathways for the introduction and spread of aquatic nuisance species (ANS).
		However, the rate of compliance was found to be inadequate, and vessel operators often failed to submit mandatory ballast water reports to the Coast Guard during this timeframe.

		However, open-sea ballast water exchange is not completely effective in preventing the spread of alien invasive species, largely because 100 percent exchange of the ballast water cannot be guaranteed.
		Such vessels are exempt from the mandatory ballast water exchange testing and enforcement actions currently required of vessels entering the Great Lakes, even though they can typically contain a significant residual quantity of unpumpable ballast water and sediment, estimated to range between 50 and 450 tonnes per ship.
		The taking on of ballast water is a long-standing practice in the shipping industry, as a means of enhancing the safety of ship operation by increasing vessel stability and maneuverability.

	Biological Pollution: Great Lakes Ballast Technology Demonstration Project
		All ballast water was treated for a period of two months prior to testing to minimize concern of leakage of untreated water from other parts of the system into the treated water.
		Most importantly it will subject the system to the wide variety of physical, biological and chemical water quality parameters that ballast treatment will need to address within the source water of the harbors that the ship visits and the ballast tanks of the ship itself.

		If you are concerned about the problems with ballast water release, contact your state and federal representatives to draw their attention to this problem and ask them to look into measures that control the release of exotic organisms from ballast water.
		Most of the current strategies to deal with the problems posed by ballast water focus on minimizing transport and recommend exchanges where ships discharge and refill their ballast tanks in the open ocean.

	STEMMING THE TIDE
		Ballast is defined as any solid or liquid placed in a ship to increase the depth of submergence of the vessel in the water (the draft), to change the trim, to regulate the stability, or to maintain stress loads within acceptable limits.
		Ballast water is generally used in preference to solid ballast because of reduced loading times and increased vessel stability during a voyage.
		The biota in ballast water are correspondingly diverse, and predicting the presence of a particular unwanted species in a particular vessel or certifying a particular vessel as free of or safe from all unwanted species is extremely difficult.

	OptiMar Ballast System Home
		Around the world more than 10 billion tons (m3/h) of ballast water are carried in ships each year containing thousands of species of aquatic animals and plants, creating problems for the marine environment and human health, threatening the aquatic flora and economies that depend on healthy aquatic ecosystems.
		Ballast water exchange requires a vessel to pump 3 times the volume of the water to replace less than 95%.
		The transportation of ballast water cannot be stopped, but the transfer of harmful aquatic organisms and pathogens can be minimized by deep sea exchange or suitable treatment.

	Environmental Issues
		With the open-minded approach to new ballast water treatment techniques it appears then that the future will be the development of minimum standards at which these techniques should perform to, for example, the methods should destroy 95% of the organisms present in the ballast water.
		This is a key issue for INTERTANKO owing firstly to the vast amounts of ballast water carried by the world's tanker fleet and secondly, to the potential environmental damage that the alien species carried in these vast quantities of ballast water could cause.
		If the organisms in the ballast water survive the journey and if various biological and physical parameters are correct, then there is the chance that the organism will survive in the new environment.

	MITSG CCR: Marine Bioinvasions: Conference Abstracts
		Ballast water exchange is being promoted nationally and internationally as a management strategy to (1) decrease the abundance of coastal organisms within ships’ ballast water and thereby (2) reduce the risk of future invasions by nonindigenous species.
		The overall effect of ballast water exchange in reducing invasions therefore depends not only upon (a) the percent of vessels that exchange their ballast water and (b) the methods and results of exchange per vessel, but also (c) the relationship between supply and invasion rates.
		Ballast water sediments and hull fouling organisms are being collected randomly from commercial vessels arriving in Hawaii from foreign and U. mainland ports.

		Lisiecki said ozone-treated ballast water is safe to be pumped back into seawater.
		Tankers bound for Valdez usually take on water from the Puget Sound in Washington or ports in San Francisco or Long Beach, Calif. Ballast water stabilizes a ship and lowers the draft of a vessel so its propellers are underwater.

		Ballast water discharged from ships is one of the largest pathways for the introduction and spread of aquatic nuisance species (ANS).
		On June 14, 2004, the Coast Guard published regulations establishing penalties for ships headed to the U.S. that fail to submit a ballast water management reporting form, as well as vessels bound for the Great Lakes or portions of the Hudson River that violate mandatory ballast water management requirements.

		Sikkema and numerous others concerned by this unprecedented change in natural ecosystem balances agree that treating ballast water -- which would entail adding chlorine to ballast water to kill any resident stowaways, then dechlorinating before discharge -- is the key to stemming the invasion.
		Although many research projects are underway to look into effective treatment of ballast water, industry representative Jermain stressed that any method would have to pass muster for maintaining structural integrity of the ships.

		To rise again to the surface, it has to purge the ballast tanks by blowing air into them, forcing the water out and lowering the submarine's density.
		To submerge, it has to take in water in "ballast tanks", increasing its density above that of water and causing it to sink.
		From this observation, it is also apparent after a moment's thought that if multiple pipes of different diameter are stuck into the top of a sealed vessel and the vessel is overfilled with water, that water will be at the same level no matter the diameter of any individual pipe.

	NBIC: National Ballast Information Clearinghouse
		The National Ballast Information Clearinghouse (NBIC) is a joint program of the Smithsonian Environmental Research Center (SERC) and the United States Coast Guard that collects, analyzes, and interprets data on the ballast water management practices of commercial ships that operate in the waters of the United States.
		The principal aims of NBIC are to quantify the amounts and origins of ballast water discharged in US coastal systems and to determine the degree to which such water has undergone open-ocean exchange or alternative treatments designed to reduce the likelihood of ballast-mediated invasions by exotic species.

		Although it is under increased criticism, exchanging the harbor water in ballast tanks for seawater from the open ocean is still the only tool available to ship owners, he said.
		Bilney stressed the need to keep ballast water exchange at sea on the list of available tools until a realistic effective alternate is available.
		Rushing to demand that ships must "sterilize" billions of tons of ballast water in the absence of reasonably effective technologies will only compound the crisis.

	MITSG CCR: Welcome
		Ballast exchange reduces ANS by 1) discharging a percentage of them into the inhospitable environment of the ocean, and in some cases, 2) by increasing the salinity level within the ballast tank to a level such that the species of freshwater or brackish water origins cannot survive.
		During exchange, a vessel replaces its original ballast water (taken on board while the vessel was in port or near to the coast) with water from the open ocean.
		The ballast water forums were held at various locations along the west coast, and were well attended by regulators and maritime industry representatives.
