Public Information Booklet Vessel Management Questions: � How is bilge from vessels managed including invasive marine species and how are invasive species attached to ships hulls managed? � How and where will company empty the ballast water? The risk and management of invasive marine species is an issue for all ports around the world. This is an area of strong focus by both the State and Commonwealth governments with legislation in place to manage the risk relating to the potential spread of invasive marine species. All Precinct proponents will need to manage potential invasive marine species in compliance with the legislation and any conditions that are set via the Strategic Assessment and other relevant environmental approvals. This will also involve trying to understand what invasive marine species may already exist in and around James Price Point as well as at Broome Port and how they should be managed so they donít spread any further/as well as measures to prevent the potential introduction of new species from elsewhere. There are a number of ways that invasive marine species could be introduced with the main two being via ballast water (i.e. from the bilge) or on the hull of a vessel. Management of ballast water is relatively well understood and is regulated by the Australian Quarantine Inspection Service. Ships are generally required to flush their ballast water tanks while out in the deep ocean (deep water species generally donít survive closer to the coast and visa versa). They are then required to complete a report and provide it to the government. Management of invasive marine species on the hull is the current focus of regulatory development and management practices. Australian National Biofouling Management Guidelines have been prepared as a collaborative effort by the Australian State and Northern Territory governments, marine industries, researchers and conservation groups. These guidance documents were released in 2009 as part of the National System for the Prevention and Management of Marine Pest Incursions. The Precinct proponents would be required to meet these requirements along with any conditions set as part of the Strategic Assessment. In practice, this typically means proponents will need to understand the history of where a vessel has been, its potential for being affected by invasive marine species and where necessary having divers inspect the vessels prior to them being used. If invasive marine species are identified, measures may be able to be put in place to remove these prior to the vessel being utilised. If a proponent canít be certain these issues have been dealt with and there is a significant risk invasive marine species may be introduced from the vessel, there may also be the option of looking for more appropriate vessels. Question ñ How many and what type of boats/ships will there be during construction and operations and where will the shipping lanes be located? The number of vessel movements required during the foundation proponentís initial construction phase has not been determined as yet and this is dependent on the 5279225 67
Public Information Booklet construction techniques, site location, bathymetry and metocean conditions. Vessels are likely to be utilised for: � Jetty construction; � Module transport; � LNG processing vessels and equipment import; � Rock import; � Pipeline installation; � Breakwater construction; � Dredging; and � Bulk supplies for upstream and downstream aspects of the development as well as drilling activities. Vessel use will be distributed over the full construction period. At the height of the construction the number of vessels off the James Price Point area could be in the order of 20 at any one time. These activities will be coordinated and managed to minimise the impacts to the environment. Figure 39: Supply boat and lay barge 5279225 68
