National Aquatic Invasive Species Act of 2007

Mr. President, today, my colleague from Maine, Senator Collins and I are very pleased to introduce the National Aquatic Invasive Species Act of 2007. This bill, which reauthorizes the Nonindigenous Aquatic Nuisance Prevention and Control Act, takes a comprehensive approach towards addressing aquatic nuisance species to protect the nation=s aquatic ecosystems. Invasive species are not a new problem for this country, but what is so important about this bill is that it to takes a comprehensive approach toward the problem of aquatic invasive species rather than just focusing on species after they are established and a nuisance. The bill deals with the prevention of new introductions of species, the screening of live aquatic organisms imported into the country, the rapid response to new invasions before they become established, and the research to implement the provisions of this bill.

More than 6,500 non-indigenous invasive species have been introduced into the United States and have become established, self-sustaining populations. These species B from microorganisms to mollusks, from pathogens to plants, from insects to fish to animals B typically encounter few, if any, natural enemies in their new environments and often wreak havoc on native species. Aquatic nuisance species threaten biodiversity nationwide, especially in the Great Lakes.

In fact, the aquatic nuisance species became a major issue for Congress back the late eighties when the zebra mussel was released into the Great Lakes. The Great Lakes still have zebra mussels, and now, more than 20 states are fighting to control them. They have traveled down the Mississippi River, then up the Arkansas River over to Oklahoma, and zebra mussels have been found out even in Nevada and California. From 1993 to 2003, rapidly multiplying zebra mussels caused $3 billion in damage to the Great Lakes region. Industry and municipalities spend millions to keep water pipes from becoming clogged with zebra mussels. And that is just the economic impact that one species has caused.

Zebra mussels were carried over from the Mediterranean to the Great Lakes in the ballast tanks of ships. The leading pathway for aquatic invasive species was and still is maritime commerce. Most invasive species are contained in the water that ships use for ballast to maintain trim and stability. There are over 180 aquatic invasive species in the Great Lakes. Some of the more notorious aquatic invaders such as the zebra mussel and round goby were introduced into the Great Lakes when ships pulled into port and discharged their ballast water. In addition to ballast water, aquatic invaders can also attach themselves to ships= hulls and anchor chains.

Because of the impact that the zebra mussel had in the Great Lakes, Congress passed legislation in 1990 and 1996 that has reduced, but not eliminated, the threat of new invasions by requiring ballast water management for ships entering the Great Lakes. Today, there is a mandatory ballast water management program in the Great Lakes, and the Coast Guard recently turned the voluntary ballast water exchange reporting requirement into a mandatory ballast water exchange program for all of our coasts. The current law requires that ships entering the Great Lakes must exchange their ballast water, seal their ballast tanks or use alternative treatment that is Aas effective as ballast water exchange.@ Unfortunately, alternative treatments have not been fully developed and widely tested on ships because the developers of ballast technology do not know what standard they are trying to achieve. This obstacle is serious because ultimately, only on-board ballast water treatment will adequately reduce the threat of new aquatic nuisance species being introduced through ballast water.

Our bill addresses this problem by setting a ballast discharge standard. After 2011, all ships that enter any U.S. port after operating outside the Exclusive Economic Zone of 200 miles will be required to use a ballast water treatment technology that meets the ballast technology standard. This standard is based on the standard proposed by the International Maritime Organization but is more protective of our waters by a factor of 100. The standard would ensure that ships discharge water that has less than 1 living organism that is greater than 50 micrometers per 10 cubic meters of water. If the Coast Guard determines in 2010 that technology is not available that can meet this standard, then the Coast Guard and EPA would establish a standard for ballast water management based on the best performance available that exceeds the international standard. Technology vendors and the maritime industry will know what standard they should be striving to achieve and when they will be expected to achieve it.

I understand that ballast water technologies are being researched, and some are currently being tested on-board ships. The range of technologies includes ultraviolet lights, filters, chemicals, deoxygenation, ozone, and several others. Each of these technologies has its own merits, and each has a different price tag attached to it. This bill will not overburden the maritime industry with an expensive requirement to install technology because the market for technology to meet a domestic and an international standard is evolving into a competitive market, and that competition will provide affordable technology.

Technology will always be evolving, and we hope that affordable technology will become available that completely eliminates the risk of new introductions. Therefore, it is important that the Coast Guard regularly review and revise the standard so that it reflects what the best technology currently available is.

Mr. President, there are other important provisions of the bill that also address prevention. For instance, the bill encourages the Coast Guard to consult with Canada, Mexico, and other countries in developing guidelines to prevent the introduction and spread of aquatic nuisance species. The Aquatic Nuisance Species Task Force is also charged with conducting a pathway analysis to identify other high risk pathways for introduction of nuisance species and implement management strategies to reduce those introductions. And this legislation, establishes a process to screen live organisms entering the country for the first time for non-research purposes. Organisms believed to be invasive would be imported based on conditions that prevent them from becoming a nuisance. Such a screening process might have prevented such species as the Snakehead, which has established itself in the Potomac River here in the DC area, from being imported.

The third title of this bill addresses the early detection of new invasions and the rapid response to invasions as well as the control of aquatic nuisance species that do establish themselves. If fully funded, this bill will provide a rapid response fund for states to implement emergency strategies when outbreaks occur. The bill requires the Army Corps of Engineers to construct and operate the Chicago Ship and Sanitary Canal project which includes the construction of a second dispersal barrier to keep species like the Asian carp from migrating up the Mississippi through the Canal into the Great Lakes. Equally important, this barrier will prevent the migration of invasive species in the Great Lakes from proceeding into the Mississippi system.

Lastly, the bill authorizes additional research which will identify threats and the tools to address those threats.

Though invasive species threaten the entire nation=s aquatic ecosystem, I am particularly concerned with the damage that invasive species have done to the Great Lakes. There are now roughly 180 invasive species in the Great Lakes, and on average, a new species is introduced every 8 months. Invasive species cause disruptions in the food chain which is now causing the decline of certain fish. Invasive species are believed to be the cause of a new dead zone in Lake Erie. And invasive species compete with native species for habitat.

This bill addresses the ANOBOB@ or No Ballast on Board problem which is when ships report having no ballast when they enter the Great Lakes. However, a layer of sediment and small bit of water that cannot be pumped out is still in the ballast tanks. So when water is taken on-board and then discharged all within the Great Lakes, a new species that was still living in that small bit of sediment and water may be introduced. By requiring that these ships immediately begin saltwater flushing so that freshwater species cannot survive in the saltwater being pumped through the ballast tank, this bill addresses a very serious issue in the Great Lakes. In 2012, these NOBOB ships, like all ships, will be required to install and use ballast technology.

All in all, the bill would cost about $150 million each year if authorized funding were to be fully appropriated. This is a lot of money, but it is a critical investment. As those of us from the Great Lakes know, the economic damage that invasive species can cause is much greater. The zebra mussel, which is just 1 of the 180 species that has invaded the Great Lakes, has caused $3 billion in economic damage over 10 years. Imagine what the cost of zebra mussels is to all of the states that are now dealing with them. Compared to the annual cost of zebra mussels and the hundreds of other aquatic invasive species, the cost of this bill is more than reasonable. Therefore, I urge my colleagues to cosponsor this legislation and work to move the bill swiftly through the Senate.
