Public Information Booklet small slope downwards towards the flare, to make sure that any liquids run into the flare drum, and do not run backwards and block the flare piping. This is an important safety requirement. Placing the flares away from the coast may require piping to be placed higher than the current design and make it easier to see further away. Accommodation Questions: � What are the requirements for the accommodation camp? � Will Woodside build on a town site or not and why? The current requirement for the location of construction and operations accommodation is 3 to 5 kilometres (1.9 to 3.1 miles) from the plant boundary. This is due to concerns in relation to safety, cost and community impact. Safety An accommodation facility or camp is really a place for people to live while they are working. This means it falls in the category of a ësensitive land useí and therefore must meet the defined Environmental Protection Authority requirements. As a result, the accommodation facilities must be located at least 3 kilometres (1.9 miles) away from the LNG facilities. However the maximum distance away should be kept to about 5 kilometres (3.1 miles) as increasing this distance further adds to the risk of road accidents for up to 3,500 people travelling per day to and from work. Increasing the 5 kilometres (3.1 miles) journey to (say) 20 kilometres (12 miles) provides 4 times the risk of accident and injury, possibly more. This is because the more driving that is done at say 100 kilometres per hour on country roads might mean more accidents due to issues relating to tired drivers not paying attention, wildlife/animals venturing onto the road at dawn and dusk and other times of the day as well as other road users driving at high speeds on the road. Cost With a shorter distance from the plant, each bus with workers on it can complete lots of trips in a short amount of time meaning a smaller number of buses and drivers required. Community Impact The construction and operation phases of the plant will be on a 24 hour shift basis. It is important for the wellbeing of the workers that the accommodation is located reasonably close to the Precinct. The early thinking is that the accommodation will be high quality and have a variety of recreational facilities contained within it (particularly for construction). This will assist in lowering the impact on Broome and Dampier Peninsula communities. 5.3. Shore Crossing and Coastal Impacts Question: 5279225 55
Public Information Booklet What is the area of land required for shore crossing? A shore crossing for an LNG facility at the Precinct is critical for the operation of the facility. The shore crossing across the beach and associated corridor connecting it to the main LNG facility is required to carry several important pieces of infrastructure. There are two types of corridors required for the LNG Precinct. The first is for the pipelines coming from the gas fields offshore and include: � Multiple large pipelines that carry the gas and liquids in from the gas field (and offshore facilities). As these are high pressure gas pipelines they need to meet appropriate safety requirements to ensure they are appropriately separated from each other; roads and areas of public access. � Return lines that pump the chemicals recovered from the liquid stream back offshore to the gas fields. This primarily consists of Monoethylene Glycol (MEG) which is an anti-freeze very similar to what is put in car radiators in colder climates. The large pipelines need to cross the shore a safe distance from the area that ships will operate in to maintain safety of the facilities. The second type of corridor is for the loading the LNG onto ships and connecting the LNG facilities to the Materials Offloading Facility (MOF). The items in this corridor include: � LNG loading lines are required to carry the LNG from the tanks to the ship and gas (LNG) vapour from the ship back to the LNG facility. Consequently two lines are needed for each berth; � Condensate (light oil) loading lines are required to load the condensate from the storage tank out to the loading berth; � Liquefied Petroleum Gas (LPG) loading lines need to be allowed for in case a future proponent produces LPG if it needs to be removed from the gas to meet the LNG specification requirements; � A haul road is needed to connect the Materials Offloading Facility to the LNG plant to carry the large modules (potentially up to 10,000 tonnes) up to the LNG facility. This haul road requires about 75 metres (82 yards) of width); � Access road to the jetty for workers and maintenance equipment; � Various other utilities also need to be supplied including power, water, communications, etc. As the Precinct is designed to be expanded in the future the corridor and beach crossing has to allow enough room for the facilities that will already be operating and the installation of the new facilities to support expansion while the existing facilities remain in use. For example when a new pipeline from the sea is pulled ashore this cannot occur too close to an existing pipeline that is already operating so that the safety of the workers, community and environment is maintained. 5279225 56
