2.0 PROJECT DESCRIPTION - OVERVIEW

Shipping activities during operation of the QGC Facility are anticipated to include:

▪ Movement of operations personnel and material within the Port of Gladstone; and

▪ LNG carriers through the Port of Gladstone and the Great Barrier Reef Marine Park (GBRMP).

2.1 Key Nodes – Operations Personnel and Material

A summary of key QGC Project Nodes for shipping activities in the Gladstone Region and a brief description of logistics activities associated with each, is provided below.

2.1.1 Curtis Island Facilities

QGC Marine Transport Nodes on Curtis Island include:

▪ The LNG Jetty at Curtis Island, including specialised LNG Loading Facilities.

▪ A Materials Offloading Facility (MOF / QC4) on Curtis Island. During operation of the LNG Facility, this will be the primary access point to the site utilised for:

▪ Personnel ferries

▪ Delivery of materials and equipment to the site, and removal of wastes from the site.

▪ A Construction Dock (CD / QGC3) consists of a floating pontoon, concrete ramp and materials dock on Curtis Island. The floating pontoon is used to transfer regulators, LNGC maintenance personnel, ship’s crew, shipping agent and cargo survey to and from the vessel. The concrete ramp is used by the RO/RO to supply material and equipment for the PDS and pipeline when required by upstream or should QC4 Linkspan not be available. Both the pontoon dock and concrete ramp is an alternative emergency evacuation point. The large materials dock adjacent to the concrete ramp will be preserved should construction of another facility be approved in the future. .

2.1.2 Gladstone Mainland

Marine Operations Terminal

The Marine Operations Terminal (MOT), within Gladstone Port (RG Tanna bulk storage facility), is the key staging point for transport of personnel, material and equipment to and from Curtis Island during Operations.

This facility includes access for passenger ferries for personnel to and from the LNG Facility on Curtis Island, and roll-on roll-off (RORO) capability for trucks carrying materials and equipment to and from the facility.

The location, layout and transport routes associated with this facility are shown in Figure 1.

3.0 VESSEL MOVEMENTS

3.1 Port Curtis – Movements of Operations Personnel, Materials and Equipment

3.1.1 Vessel Specifications

Specifications for vessels used to support LNG operations are outlined below:

▪ Passenger Ferry: Length Over All (LOA) - 30 to 45m, Draft - 2m, Maximum Speed 25 knots, Passenger Capacity - 150 to 400.

▪ Barge Ro/Ro: LOA - 35 to 45m, Draft - 4.0m, Maximum speed -10 knots.

▪ Passenger Ferry (Small): LOA – 15 to30m, Draft - 1.0m, Maximum speed – 25 knots, Passenger Capacity - 20 to 140.

▪ Security Boat: LOA - 5 to 15m, Draft - 1.0m, Passenger Capacity 25 – 50 Maximum speed – 25 knots.

3.1.2 Personnel

During normal operations, personnel will transit from the MOT on the Gladstone mainland to the QGC Facility daily. This will consist of regular scheduled passenger services, plus additional water taxi or other personnel movements to address emergency or ad-hoc requirements. An indicative timetable for the regular schedule passenger service is provided in Table 1 below, though this will be subject to further refinement.

It should be noted that during periods of high maintenance activity, especially Plant Turnarounds, movements of both personnel and materials will be different from those outlined below. Turnarounds will occur indicatively once per year per LNG train in the first few years, then once every 3 years per train as the operation matures. Turnarounds will typically last for a period of 14 to 21 days.

3.1.3 Materials and Equipment

In addition to the passenger movements outlined above, ferry / barge services will operate transporting materials and equipment to the QGC Facility and removing wastes. These will also depart from the MOT to the MOF. Roll On-Roll Off (RO-RO) cargo barges will typically run twice per day to QGC but may increase to three times per day during Turnaround events.

In addition to the above, there may be ad-hoc movement of water taxis carrying small numbers of personnel outside the scheduled ferry times.

3.1.4 LNG Carrier Operations

LNG carrier operations are described in the QGC Shipping Transport Management Plan (STMP) (LNGOP-QL00-MRN-PLN-000001), which provides detail on types and sizes of LNGCs, pilotage requirements (both within the Port and Gladstone and elsewhere in Australian territorial waters, including the Torres Strait and northern section of the Great Barrier Reef). This STMP has been approved by Maritime Safety Queensland. A summary is provided in the sub-sections below.

3.1.5 Type and Sizes of Ships

The ship design criteria for mooring and loading at QGC’s jetty is vessels with capacities ranging from 125,000 m3 to 220,000 m3, Moss or Membrane design LNG Carriers. This range of vessels, with arrival drafts to 11.0m and laden drafts to 12.2m, and length over all (LOA) to 315 m x 55 m beam have been simulated in the Gladstone channels and found acceptable.

3.1.6 Pattern of Operation

QGC cargoes will trade internationally to Asia, including Singapore, China, Taiwan, Japan, Korea, and India.Under normal operating conditions there will be approximately 2 - 3 ship LNGC loadings per week.

3.2 Vessel Routes

3.2.1 Port of Gladstone

QGC shipping routes within the Port of Gladstone are shown in Figure 2 below. It should be noted that these routes are indicative only and may vary due to factors including (but not limited to) tidal or meteorological conditions, other harbour traffic, the requirements of the Gladstone Harbourmaster, vessel type, and further refinement of Project planning.

Shipping routes will be subject to “Go Slow – Wildlife” speed restriction zones as specified in Section 5.0.

LNGCs which arrive at the Port of Gladstone before their channel allocation may anchor in a designated LNG anchorage to be established at the eastern edge of the Gladstone Eastern Anchorage.

When LNG carriers anchor, once ready for the transit through the Port to the QGC Facility, each LNG carrier will be met by a Gladstone pilot, subject to weather conditions being appropriate for the transit and for berthing at the LNG Facility. Weather monitoring instruments are mounted on beacon “S16” and various other locations in the port, including the QGC jetty, and the final determination for safe boarding conditions is with the pilot and ship’s master at the time.

The pilot and ship’s master will exchange manoeuvring information about the LNGC and the anticipated transit. The pilot will perform a series of checks to verify the equipment is operational. The pilot will contact Gladstone REEFVTS for permission to enter the channels and to confirm that the channels ahead are clear of outbound traffic.

The total distance from the commencement of pilotage to QGC is approximately 24.5 nm. Transit time is approximately 3 hours depending on the environmental conditions at the time, excluding swinging and final berthing manoeuvres.

Between the Fairway buoy and the entrance to Wild Cattle Cutting, two 80 ton escort tugs supplied by GPC’s tug provider will connect at S28 and escort the LNGC. Once inside the harbour, tow 70 ton bollard pull harbour tug will connect (to assist the LNGC to the berth.

Transit speed will be reduced to 8 kts through the water passing Barney Point Wharf (6 kts through the water if Barney Point Wharf is occupied).

Clinton Bypass channel is the normal route for LNG Carrier transits in and out. However, in exceptional circumstances, the Clinton Main Channel could be utilised, provided precautions are taken for passing ship interactions for any ships moored at RG Tanna Wharf.




4.0 SHIPPING WITHIN THE GREAT BARRIER REEF MARINE PARK

Shipping associated with the Project undertaken through the Great Barrier Reef Marine Park (GBRMP), terminating in Gladstone, will be specific to LNG carrier operation and LNG carrier activity.

Environmental risks related to shipping within the Great Barrier Reef can occur from the routine discharge of pollutants during normal ship operations, or as a result of accidents or incidents. Potential impacts include:

▪ Spills or discharges of oil, chemicals, cargo, sewage and grey water;

▪ Garbage and marine litter;

▪ Collisions with marine animals;

▪ Toxic effects of anti-fouling paints;

▪ Physical damage from groundings and anchoring;

▪ Ecosystem changes resulting from the introduction of invasive marine pests; and

▪ Shipping noise.

4.1 Management of Shipping within the Great Barrier Reef Marine Park

When transiting the GBRMP, LNG carriers will navigate within the designated shipping areas and the general use zone.

The designated shipping area has been placed to minimise the impact on the shipping industry while having regard for Australia's international obligations. It takes into account past and forecast vessel usage patterns in the inner and outer shipping routes, existing recommended tracks and proposed new routes. The designated shipping area as specified by the Great Barrier Reef Marine Park Authority (GBRMPA) is shown in Figure 4.

In addition to the Great Barrier Reef designated shipping areas, the Australian Maritime Safety Authority has prepared the Queensland Coastal Passage Plan and the North-East Shipping Management Plan, intended to ensure co-operation between government agencies and industry in ensuring protection of the environment of the Great Barrier Reef. Each plan “outlines measures currently in place to manage the safety of shipping in the sensitive marine environments of Australia’s north-east region and propose options to minimise the environmental impacts of these activities in the years to come”.

Pilotage, Great Barrier Reef and Torres Strait Vessel Traffic Service (REEFVTS), vessel inspection and auditing and other requirements on LNG carriers are outlined in Section 5.0

QGC LNGCs will typically use the outer Barrier Reef route except when meteorological conditions favour the inner route.




Figure 4: Great Barrier Reef Designated Shipping Area




4.2 International and National Requirements for Shipping Operations in Australian

Waters

A number of international and national management arrangements and obligations apply throughout all Australian waters, including the Great Barrier Reef. The management framework for shipping activities is determined by a series of international conventions that are implemented through Australian law. These international conventions and regulations include:

▪ United Nations Convention on the Law of the Sea 1982;

▪ International Convention for the Prevention of Pollution from Ships 1973 and the 1978 Protocol (MARPOL 73/78) (see Management actions applied to shipping in the Great Barrier Reef);

▪ International Regulations for Preventing Collisions at Sea 1972 (COLREGS); and

▪ International Convention for the Safety of Life at Sea 1974 (SOLAS).

All international conventions will be complied with and routine inspections will be conducted by AMSA.

4.3 Regulatory Framework

These conventions are implemented within Australia and the Great Barrier Reef region and administered by the Australian Maritime Safety Authority, the Department of Transport and Regional Services, the Department of the Environment and Energy, Maritime Safety Queensland and the Great Barrier Reef Marine Park Authority through the following articles of legislation:

4.3.1 Australian Maritime Safety Authority

▪ Navigation Act 1912;

▪ Protection of the Sea (Prevention of Pollution) from Ships Act 1983;

▪ Protection of the Sea (Powers of Intervention) Act 1981;

▪ Protection of the Sea (Civil Liability) Act 1981;

▪ Marine Safety (Domestic Commercial Vessel) National Law Act 2012 (and associated Regulation);

4.3.2 Department of and Transport and Regional Services

▪ Maritime Transport Security Bill 2003;

▪ Transport Safety Investigation Act 2003;

4.3.3 Great Barrier Reef Marine Park Authority

▪ Great Barrier Reef Marine Park Act 1975;

▪ Great Barrier Reef Marine Park Regulations 1983;

▪ Area Plans of Management;

4.3.4 Maritime Safety Queensland

▪ Transport Operations (Marine Safety) Act 1994;

▪ Transport Operations (Marine Pollution) Act 1995;

4.3.5 Department of Agriculture, Water and Environment (formerly Department of Sustainability,

Environment, Water, Population and Communities)

▪ Environment Protection and Biodiversity Conservation Act 1999;

▪ Environment Protection (Sea Dumping) Act 1981;

▪ Historic Shipwrecks Act 1976;

▪ Sea Installations Act 1981.

The Commonwealth MARPOL implementing legislation includes a number of enforcement related provisions derived from the United Nations Convention on the Law of the Sea. These are:

▪ Extension of the application of the Act to the exclusive economic zone (EEZ) (section 6)

▪ Provisions which require foreign ships to provide information (section 26G);




▪ Detention of foreign ships suspected of involvement in pollution breaches. (The ship must be released on the posting of a bond or in the event of other circumstances arising as listed in the Act - section 27A);

▪ Provision that detention may include escorting a ship into port (subsection 27A(1A));

▪ Provision to ensure that proceedings in Australia against a foreign ship for a pollution breach will be suspended if proceedings for the same pollution breach are taken in the flag state of the ship (subsection 29(2));

▪ Provision of specific powers relating to inspection of ships in the EEZ which are suspected of having caused a pollution breach; and

▪ A requirement for an Australian ship that is in the territorial sea or the EEZ of a foreign country to provide information required by that country to determine if a pollution breach has occurred (section 27C).

The Transport Operations (Marine Safety) Act 1994 (Qld) requires marine safety and implementation of marine safety strategies, whilst the Transport Operations (Marine Pollution) Act 1995 (Qld) regulates disposal of waste from vessels, and requires marine pollution strategies and pollution response plans in coastal waters.

The GBRMPA administers the legal requirements of the Great Barrier Reef Marine Park Act 1975 and associated Regulations, including the compulsory use of local pilots for certain ships within prescribed areas, restrictions on certain activities (for example, waste discharge, negligent shipping), wreck removal and penalties for causing environmental damage to the Marine Park. The GBRMPA regulates the entry and use of the Marine Park by ships and boats through the Great Barrier Reef Marine Park Zoning Plan 2003.

The Environmental Protection (Sea Dumping) Act 1981 (Cth) and MARPOL limit discharge of wastes and applies to all vessels in Australian waters.

The Navigation Act 1912 provides powers for the inspection and detention of unseaworthy or substandard vessels under s. 190AA(1) and s.210(1). All Shipping Activities associated with the Project will be undertaken in accordance with the above applicable International Protocols, and applicable Australian and Queensland legislation.




5.0 KEY PORT CURTIS SPECIES, HABITATS AND PROTECTION MEASURES

The Shipping Approval requires identification of habitats and activities in relation to the following EPBC listed species:

Subsequent to publication of the QGC EIS, monitoring of seagrass during the Western Basin Dredging and Disposal Project (2011 – 2013) indicates that seagrass presence in the Western Basin Project may be highly seasonal and only occurs during seagrass growing season (Rasheed et al., 2012; McCormack et al., 2013). Apart from this natural seasonal variability, seagrass abundance (during the seagrass growing season) has remained constant with the exception of 274 hectares of direct seagrass lost resulting from the construction of the Western Basin reclamation area. This loss now results in approximately 6972 ha of intertidal (coastal) seagrass beds. Western Basin Dredging and Disposal Project monthly seagrass monitoring reports are located at www.westernbasinportdevelopment.com.au/environmental_reports/section/environmental.

The geographic locations of known turtle nesting beaches, and seagrass extent, in relation QGC construction shipping in Port Curtis is shown in Figure 5: QGC Port Curtis Operations Shipping in relation to Turtle Nesting Beaches and Seagrass Distribution (seagrass extent shown based on surveys undertaken June 2010, November 2010 and November 2011, 2012 and 2013) .

Port Curtis is located within the Rodds Bay Dugong Protection Area (DPA), with this area covering the entire coastal zone between Rodds Bay and the Narrows. The extent of the Rodds Bay DPA is shown in Figure 6, with all QGC shipping activities within Port Curtis occurring within the Rodds Bay DPA.

Known locations of Water Mouse (Xermoys myoides) are described in the approved QGC Environmental Management Plan - Water Mouse (Xeromys myoides) (document QCLNG-AUS-PMT-ENV-PLN-0675) (Water Mouse Management Plan).

A commitment of the QGC Environmental Management Plan - Water Mouse (Xeromys myoides) was to undertake annual water mouse surveys during construction, and five years post construction of the Narrows Crossing Project. Water mouse surveys ended in 2016 when water mouse populations returned to pre-construction numbers at the Narrows Crossing Project.

QGC LNG Facility surveys were not included given the absence of water mouse during pre-clearance surveys. Subsequent survey results include:

▪ Six water mouse captures during the pre-clearance surveys June 2011;

▪ Five water mouse December 2011;

▪ No water mouse December 2012;

▪ Three water mouse captured in November 2013.

Maritime Safety Queensland has issued Port Procedures for Gladstone. QGC Project shipping was conducted in accordance with all applicable requirements of these procedures (or as otherwise directed by the Gladstone Harbourmaster).

5.1 Risk Assessment

A risk assessment of the potential impacts of shipping-related activities on the EPBC listed species specified in Condition 1(a) of the Shipping Approval has been completed, to determine the likelihood and consequence of an impact occurring on that species.

The risk assessment approach adopted has been modified from Great Barrier Reef Marine Park Authority Environmental Assessment and Management (EAM) Risk Management Framework, which involves assessing risk both before and after the implementation of mitigation actions. The criteria used to determine the likelihood and consequence of each potential impact are described in Table 4. Given that shipping activities are ongoing for a period of decades, the recovery of impacted species and habitats is described in the consequence rating of Table 4 in the context of new mitigation measures being applied that eliminate an initial impact. The likelihood rating is the probability of a defined impact occurring at a population level along the Queensland coast.

The risks associated with shipping activities have been considered in three geographic areas, as the potential mode of impact on listed species differs across the area:

▪ Inshore habitats located adjacent to the LNG facility and their associated dredged channels located west of Auckland Point, which are surrounded by tidal and subtidal flats. Shipping activities in this area comprise water taxis, barges and LNGCs under assistance from a pilot and tugs.

▪ Estuarine habitats of Port Curtis, located inside the barrier islands of Curtis and Facing Islands east of Auckland Point. Shipping activities generally include LNGCs in transit under assistance from a pilot through partially sheltered waters of Port Curtis.

▪ Offshore habitats of the Great Barrier Reef, located east of the barrier islands of Curtis and Facing Island. Shipping activities generally include LNGCs in transit through oceanic waters of the Great Barrier Reef Marine Park. Anchoring may also be carried out very infrequently within this area at designated anchorage sites.

Results of the risk assessment are presented in Table 4, Table 5 and Table 6, identifying inherent (unmitigated) risks and the residual risks to EPBC-listed species and their habitats following the implementation of mitigation and management strategies. Risks have been assessed by considering the likelihood of an impact occurring on an EPBC listed species at the population level or its habitat, rather than the risk of a single incident occurring. The consequence rating is based upon the most probable consequence for populations of EPBC-listed species and their habitats given the nature of the activity.

Results of the three risk assessments are discussed in further detail below in relation to EPBC-listed species identified in Condition 1(a) of the Shipping Approval.




Table 3: Risk Assessment Matrix

affected, either through elevated mortality,

habitat disturbance or a minor disruption to a

population over a widespread geographic

area. Recovery at habitat level would take at least a decade, with

recovery of listed species taking several

decades.

Major – Significant impact on populations of EPBC listed species and their habitats, with high levels of mortality. Recovery of habitats

would take a few decades, with

5.1.1 Summary of Results of Risk Assessment

The risk assessment identified that prior to the implementation of mitigation measures, shipping-related risks to EPBC-listed species and their habitats are highest within the inshore areas of Port Curtis, located between Auckland Point and the LNG jetty. This is because shipping activities in the area:

▪ Have water depths adjacent to channels which are shallow (generally




maximum speed of six knots while operating in waters shallower than 5m (measured at low tide). Navigational routes within a specified channel are selected based on a range of factors, including the location and dimensions of the shipping channel, the dimensions of the vessel, tide and weather conditions, marine activities also occurring in the area and navigational hazards. For purposes of operational flexibility and adaptive management the vessel master shall be free to elect from the 5 metres chart contour, onboard navigational devices (including depth sounder indicating the depths equivalent to the 5m contour), or reliance on buoys installed at transition zones. Safety is the key factor influencing the selection of navigational routes, which are chosen by the pilot. The selection of a route which has maximum depth to achieve navigational safety (clearance from the bottom) also generally has benefits in minimising impacts to marine fauna (by reducing clearance between the vessel and the bottom, thus reducing the potential for boat strike).

▪ A ship or vessel must not approach a dugong or turtle closer than 50 m while the vessel is underway, or closer than 100 m if the vessel is moving faster than planing speed. Vessel masters will keep a constant lookout for marine fauna and take action to avoid a collision where this is safe to do so;

▪ If a dugong or turtle approaches an under-way vessel closer than 50 m, the operator must ensure their gears are in neutral and, when safe to do so, move away at a speed of no more than six knots to a distance of 50 m (excludes LNG carriers);

▪ The vessel must not cause, or act in a manner to cause an adult and its young to become separated, or individuals to become separated from a group;

▪ If the vessel accidentally harms, injures, or kills a dugong or turtle, the skipper or captain must report it as soon as practicable, that is whilst on site, to the RSPCA hotline (see below) and to the QGC Lead Environmental Advisor (LNG) who will undertake notification to DAWE. The information required to report includes:

▪ Identifying the extent of injury

▪ The exact location of the incident / animal

▪ Where safe and practical, staying with the animal until advised by the GBRMPA ECSU Group or Department of Environment and Science (DES) stranding coordinator or conservation officer.

5.3 Turtles – Measures to Minimise Environmental Disturbance

As shown in Figure 5, there are known turtle nesting beaches along the ocean beaches on Curtis and Facing Island, with important turtle-nesting beaches for Flatback turtles (Natator depressus) on the east coast of Curtis Island and Facing Island and further south at Tannum Sands (approximately 15 km south of Gladstone). The majority of turtle nesting for Curtis Island occurs on South End Beach. Green turtles (Chelonia mydas) and Loggerhead turtles (Caretta caretta) nest occasionally on the beaches of Curtis Island and Facing Island, with Loggerhead turtle nests not concentrated in any particular location.

Flatback turtle nesting in Eastern Queensland commences in mid-October, reaching a peak in late November / early December and ceases around late January. Hatchlings emerge from nests during early December until around late March, with a peak of hatching in February.

Curtis Island eastern beach has been used as an index beach for monitoring population dynamics of Flatback turtles within the eastern Australian stock. Mid-season nightly census studies at Curtis Island since 1970 have shown no obvious trend in the size of the annual nesting population, with a range from approximately 35 to 80 individuals per season recorded. The Curtis Island Flatback turtle nesting population has maintained an approximately constant size over the 35 years since monitoring began.

In Southern Queensland, Green turtle nesting commences in mid to late October, reaches a peak in late December to early January and ends around late March to early April. Hatchlings emerge from nests from late December until around May with a peak of hatching in February and March. Loggerhead turtle nesting commences in late October, peaks in December and ends in early March. Hatchlings emerge from nests from late December through to April.

There are no known turtle-nesting beaches close (within 5 km) to the proposed QGC Facility. Port Curtis and surrounding waters are used by turtles for transit, feeding and resting.




Port Curtis includes significant turtle foraging habitat, particularly for Green turtles which feed on seagrass and algae. Loggerhead turtles and hawksbill turtles may also be found within Port Curtis, although they are more common at the coral reefs located offshore. Inter-nesting flatback turtles are also likely to enter Port Curtis from time to time, with the broader region offshore from Gladstone providing a feeding resource for the species.

Some foraging turtles are known to have a high degree of site fidelity, and may feed within a home range when not in a breeding migration. Disturbance from shipping activities may result in turtles avoiding an area within their home range, or continuing to forage in such an area despite the disturbance of shipping activities (increasing the risk of boat strike). The magnitude of the disturbance is directly proportional to the number of vessel movements and can be limited spatially through the use of a single navigation route rather than multiple routes.

Project shipping entering the Gladstone harbour will be along existing shipping channels and under standard harbour protocols, and will include “Go Slow – Wildlife” speed restriction zones as described in Section 5. All vessels are subject to MSQ speed restrictions within the harbour, including LNGCs. LNGCs are required to travel within the dedicated channels and travel at speeds set by the Pilot and local regulations. No other special measures are proposed apart from those in place for non QGC Project shipping activities associated with Gladstone Port.

Within Port Curtis, key risks to turtles from QGC shipping activity include:

▪ Vessel strike;

▪ Increases in the overall sky glow of the Gladstone region from ship lighting;

▪ Disturbance associated with noise and vibration from the operation of vessels;

▪ Indirect impacts on habitats such as seagrass foraging areas, reducing turtle health and resilience;

▪ Impacts arising from fuel, oil or chemical spills, or other marine discharges.

Protocols associated with vessel strike are as described for dugong (refer Section 5.0 above), including the “Go Slow – Wildlife” requirement. Mitigation measures to address spills and marine discharges are included in this section.

QGC has prepared a Long Term Turtle Management Plan (LTTMP) (QCLNG-BX00-ENV-PLN-000070) to manage the LNG Facility impacts. This document outlines the LNG Facility impacts to marine turtles and details QGC management measures. In summary, such mitigation measures include:

▪ Training of staff regarding marine megafauna and project-related risks

▪ Approach distances for turtles under various operating circumstances

▪ Procedures for monitoring fauna and reporting of incidents

▪ Vessels utilise established shipping routes to minimise the area of disturbance

▪ Use of low pressure sodium lights, and directional lights to reduce sky glow.

5.4 Water Mouse – Measures to Minimise Environmental Disturbance

The water mouse is listed as vulnerable under the Queensland Nature Conservation Act 1992 (where it is described as false water-rat) and vulnerable under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999. It is also recognised internationally as vulnerable under the IUCN Red List of Threatened Species. A species recovery outline in the Action Plan for Australian Rodents (Australian Nature Conservation Agency, 1995), and a recovery plan that is currently being developed set out research and management actions needed to support the recovery of the water mouse.

The water mouse is a small, non-arboreal, nocturnal rodent. Adults have an average head-body length of 103mm, tail length of 81mm and an average weight of 42g. Young animals have steel-grey backs and pure white bellies, but as they age the dorsal fur becomes grey-brown and spotted with small white flecks. Like the water rat Hydromys chrysogaster, the Water Mouse has small ears and a characteristic hunched body shape. However, it is much smaller and lacks the rat’s white-tipped tail.

The Water Mouse lives in mangrove communities, adjacent freshwater lagoons, swamps and sedged lakes close to coastal foredunes. In southern Queensland its mangrove habitat includes Avicennia marina, Rhizophora stylosa, Bruguiera gymnorrhiza, Aegiceras corniculatum and Ceriops tagal, often backed by either a discrete zone of sedgeland, swamp, dry sclerophyll and or by heathland. The Water Mouse is carnivorous, foraging within a home range on small crabs, shellfish and worms in mangrove habitats. Small nests are




constructed from mud in sedgelands. Threats include predation from feral animals, erosion of coastal habitat and loss of food resources through environmental impacts of coastal development.

In central Queensland, the species has only been captured within fringing mangroves in the high intertidal zone dominated by Ceriops tagal and / or Bruguiera spp. despite extensive searching in other mangrove habitats. This is possibly a reflection of the challenges presented to the species by a much higher tidal range in this area.

▪ Management measures for the Water Mouse, as well as known locations and details of additional surveys undertaken on Curtis Island that did NOT identify the Water Mouse, are described in the QGC Environmental Management Plan - Water Mouse (Xeromys myoides) (document QCLNG AUS-PMT-ENV-PLN-0675). Survey results conducted annually before and during construction of the QGC pipeline across the Narrows in accordance with the QGC Environmental Management Plan - Water Mouse (Xeromys myoides) include:

▪ Six water mouse captures during the pre-clearance surveys June 2011;

▪ Five water mouse December 2011;

▪ No water mouse December 2012;

▪ Three water mouse captured in November 2013.

▪ The QGC site does not comprise important Water Mouse habitat, due to the absence of extensive tidal flats and marine vegetation which is required by the species to feed and breed. However, the Water Mouse is known to occur at some Curtis Island locations outside of the QGC site, where such mangrove and tidal flat habitats are more extensive. Some small sections of these habitats are adjacent to the navigation channels utilised by ships servicing the QGC facility, and thus the consideration of shoreline erosion and general disturbance from shipping activities is relevant. The very low level of shipping activity and spatial separation of shipping channels (in excess of a kilometre-Figure 2) and Water Mouse habitats result in low risks for disturbance to Water Mouse and its habitats.

▪ If LNG is spilled into the water from a LNGC, it will vaporise as it reaches ambient temperature and is therefore highly unlikely to cause any significant environmental impacts. LNG is odourless, colourless, non-toxic and non-corrosive. The location where such a spill would be most likely to occur is the LNG Jetty, which is isolated from the mainland and does not contain Water Mouse habitat. The LNG loading arms of the jetty are contained within a large bund which will capture any LNG spilled during loading operations. There are also automatic isolation systems which are activated in the event that a spill occurs and which will prevent any significant volumes of LNG being spilled.

▪ In the event that a shipping incident occurred and posed spill risks for Curtis Island, Facing Island or Rodds Bay mangrove areas, then an incident response would be initiated through liaison with MSQ and GPC’s First Strike Oil Response team.

▪ Avoid landscape modifications that disturb water mouse habitat by prevention of exposure to bilge water, chemicals, sewage, oil and fuel from all ships and vessels;

▪ For any oil spill response activities near mangrove areas of Curtis Island, Facing Island or Rodd’s Bay, MSQ may choose to introduce local speed limits to prevent prolonged or repeated shoreline wash from waves produced by vessel wakes. Such speed limits would be set by MSQ, giving consideration to the circumstances of the incident.

5.5 Seagrass – Measures to Minimise Environmental Disturbance

Seagrasses are true flowering plants found between intertidal and subtidal habitats. They grow within sediments which range from coarse sands to fine muds. Seagrasses play a major role in marine ecosystem functioning including as a substrate, nursery area and providing shelter and food for organisms as well as physical stability of the coastline and seafloor. They are essential food sources for a variety of marine and estuarine organisms including dugongs, turtles, fish and macro invertebrates. Seagrasses require sunlight for photosynthesis and are therefore sensitive to changes in water quality which reduce the quantity and quality of incident light at the sea bed (e.g. increase in suspended sediment). Other environmental factors affecting seagrass include freshwater inputs from flood events, sediment deposition, changes in the concentration of nutrients and competition with algae or other benthic organisms.




Within the Port Curtis region, seagrass has been regularly monitored by the Department of Primary Industries and Fisheries (DPIF) Marine Ecology Group in collaboration with the Port Curtis Integrated Monitoring Program (PCIMP). Within the Port of Gladstone, the following six seagrass species have been identified:

▪ Halodule uninervis;

▪ Halophila ovalis;

▪ Halophila decipens;

▪ Halophila minor;

▪ Halophila spinulosa; and

▪ Zostera capricorni.

A total of 7,246 ha of intertidal (coastal) seagrass beds have been identified within the Port of Gladstone – Rodds Bay Dugong Protection Area (DPA), with an additional 6,332 ha in deepwater areas (>5m Mean Sea Level) identified to the east and south of Facing Island. No deepwater seagrass communities have been reported within the inner-port area.

Seagrass distribution and per cent cover has varied significantly within Port Curtis since 2011, following some severe flood events. Seasonal influences on temperature, riverine discharges and light intensity are also factors affecting seagrass growth at Port Curtis over periods of months, with a senescent period known to occur between February and June each year. The cumulative effects of natural and anthropogenic influences on seagrass habitats require management to improve the ecosystem function and increase resilience to future perturbations.

There are no seagrass beds in the vicinity of the QGC jetty facility, and inshore channels leading to the facility only have small areas of sparse seagrass. Shipping activities should therefore be managed to avoid the disruption of natural colonisation activities that may occur in the area, rather than protect existing habitats. Impacts associated with shipping activities result from accidental spills, anti-fouling residues and ship-borne litter. For the purposes of impacts upon DPAs and other coastal habitats, the following effects need to be considered:

▪ Direct impacts upon the animals and key habitats within the DPA

▪ Effects of response actions, e.g. use of dispersants

▪ Chronic pollution from oil trapped in mangrove and saltmarsh communities.

Control on shipping to address potential impacts in seagrass include operational control and controls relevant to incident response. Operational controls for QGC Project vessels operating within Port Curtis include:

▪ Stay within channels during transits, avoid vessel grounding, especially in proximity of seagrass meadows

▪ Use of designated anchorages or floating pontoons

▪ Spill response for LNG Operation activities will be managed in accordance with QGC Operations Emergency Response Plan – QGC Curtis Island (LNGOP-QL00-HSS-PLN-000001)

▪ Incident-related controls will be executed under the constraints of incident response planning and procedures specified by MSQ.

Areas of most concern are the mid-upper intertidal zone where spilled chemicals or oil can settle. On shorelines and bays with gentle slopes, more extensive effects may occur. Deeper water habitats may be impacted through direct response actions such as the use of dispersants. The GBRMPA’s policy on dispersant use clearly states that dispersants may be used in waters over seagrasses to protect mangrove habitats downstream. Other response actions such as shoreline washing where oil is washed off the shore into the water may also cause similar impacts should the oil mix into the water column. The approach to managing a spill incident, including the use of dispersants, would be determined by the incident controller of MSQ, based on several factors such as the spill location, type of oil spilled, weather conditions and location of sensitive environmental receptors.

Ballast water carried on board ships to maintain stability and safety at sea is recognised as a major contributor to the spread of exotic marine pests around the world. Current national ballast water requirements aim to minimise the introduction of pests of concern into Australian territorial waters (extending to 12 nautical miles from the coastline). The International Convention for the Control and Management of Ships’ Ballast Water and Sediments (BWM Convention) aims to minimise the spread of marine pests via ships’ ballast water.

QGC LNG carriers will adhere to all National and International ballast water management practices and conventions.

5.6 Summary of Control and Mitigation Measures

5.6.1 Vessel Traffic Service (VTS)

As described by the Australian Maritime Safety Authority , REEFVTS is a coastal Vessel Traffic Service which has been put in place by the Australian and Queensland Governments to improve safety and efficiency of vessel traffic and to protect the environment through a range of measures from the provision of simple information messages to ships, such as the position of other traffic or meteorological hazard warnings, to extensive management of traffic within a port or waterway. REEFVTS is operated under joint Australian and Queensland Government arrangements between the Australian Maritime Safety Authority (AMSA) and Maritime Safety Queensland (MSQ). The system is manned on a 24-hour basis from the REEFVTS Centre, situated in Townsville, North Queensland.

REEFVTS are recognised internationally as a navigational safety measure through the International Convention on the Safety of Life at Sea 74/78 (SOLAS). In particular, the provisions in SOLAS Chapter V (Safety of Navigation) Regulation 12 provides for Vessel Traffic Services and states, amongst other things, that:

The Great Barrier Reef and REEFVTS aims to:

▪ Enhance navigational safety in Torres Strait and inner route of the Great Barrier Reef by interacting with shipping to provide information on potential traffic conflicts and other navigational information;

▪ Minimise the risk of a maritime accident and consequential ship sourced pollution and damage to the marine environment in the Torres Strait and Great Barrier Reef region; and

▪ Provide an ability to respond more quickly in the event of any safety or pollution incident.

5.6.2 Pilotage

In addition to pilotage of LNG carriers described in Section 3.1.4, the IMO has designated the Torres Strait and Great Barrier Reef a Particularly Sensitive Sea Area (PSSA). This gives Australia greater powers to protect the Reef through a Shipping Management System.

A LNG Carrier must carry a licensed pilot in the Torres Strait and northern sections of the Great Barrier Reef Inner Route. Two competing coastal pilot organisations provide pilot bookings and transfers through Torres Strait, The Australian Reef Pilots, and the Torres Strait Pilots. The pilots are independent contractors, licensed by AMSA.

AMSA has implemented an Underkeel Clearance Management System for shipping through the Torres Strait for all ships with a draft of 8 m or more. The maximum draft permitted for transit is 12.2 m

5.6.3 Ship Vetting and Auditing

QGC is committed to ensuring that all LNG cargoes which are loaded at its terminal are carried safely, and with the minimum risk to people, infrastructure, and the environment. STASCO (Shell International Trading and Shipping Company Limited) is accountable for the execution of all marine assurance activities pertaining to the pre-chartering and contracting approval requirements of LNG Carriers berthing at QGC. Shell Shipping & Maritime is based in London, with specialist centres in Houston, The Hague, Singapore, Perth and Tokyo - networked to maritime professionals across the globe.

Ship vetting is the process whereby all known relevant information is used to make an assessment on whether a ship should be accepted or declined for QGC, or interact with owned or operated terminals. STASCO will obtain, from the ship owner, copies of the relevant ship’s certificates and classification society status report, consult port state control inspection and industry specific databases, and obtain the recent trading history of the ship. STASCO will obtain a recent OCIMF-SIRE inspection report before a LNG Carrier is chartered, and arrange periodic re-inspections by an OCIMF accredited inspector. STASCO may contact terminals which the ship has recently visited to form a professional opinion of the quality of the ship.

STASCO will perform vetting checks for all LNG Carriers, including third-party ships, loading at QGC according to STASCO Procedure.

STASCO will audit, as opposed to vetting, LNG Carriers owned or long-term chartered by STASCO.




In addition to vetting and auditing by STASCO, Gladstone Ports Corporation requires any LNG Carrier calling at the Port be vetted by itself. A LNG Carrier may be pre-approved by GPC at any time. QGC will submit its Annual Delivery Program annually, and its rolling 90-day cargo forecast three months in advance to GPC. Any LNG Carrier nominated on the 90-day cargo forecast which is not pre-approved may be vetted by GPC. QGC will provide the information required by GPC for vessel vetting, which in general will include:

▪ Compliance with relevant criteria published by the Australian Maritime Safety Authority;

▪ Compliance with the relevant criteria published in GPC’s LNG Shipping Protocols (Port Notice No. 4);

▪ Compliance with the relevant criteria published in MSQ’s Port Procedures for Gladstone;

▪ Name and flag of the Ship;

▪ International Maritime Organization identification number;

▪ Name of the Ship’s agent;

▪ Port of Registry;

▪ Gross tonnage / net register tonnage / dead weight tonnage;

▪ Signed protection and indemnity insurance certificate; and

▪ A description of the Ship

5.6.4 Limits on Vessel Speeds

Limits on vessel speeds to address potential risk of vessel strike to dugong turtle are outlined in Section 5 and Appendix A.

Additional controls on vessel speed may be applied at the direction of the Gladstone Harbourmaster to address safety or navigability issues.

5.6.5 Limits on Vessel Movements, including the Use of Thrusters

Vessel movements will typically occur along the routes outlined in Figure 2, although as noted these routes are indicative only and may vary due to factors including (but not limited to) tidal or meteorological conditions, other harbour traffic, the requirements of the Gladstone Harbourmaster, vessel type, and further refinement of Project planning.

Bow thrusters are predominantly used during the berthing process at the LNG Jetty on Curtis Island. Given the limited extent of seagrass in proximity to the proposed vessel routes within Port Curtis, and the absence of confirmed Water Mouse presence along the foreshore in the immediate vicinity of the LNG Facility site, no limits on use of thrusters are proposed other than standard requirements of MSQ and the Gladstone Harbourmaster.
