1 General Overview

Boral Resources (Qld) Pty Limited has been contracted to upgrade the runway on Norfolk Island Airport. This will primarily involve installing approximately 30,000 tonne of asphalt over the existing runway pavements.

The asphalt is made up of a combination of bitumen, sand and graded rock aggregates. There is no sand available on the island, and while there is an existing quarry, at Cascade, it has not need used for 14 years. The Cascade Quarry cannot provide the aggregate required for a number of reasons including, but not limited to:

• There are no current approvals for extractive industry nor a Development Approval. An approval could take several years. • An on island drilling investigation revealed there is not sufficient suitable accessible rock for the Airport Project requirements. • Part of the existing quarry is on at least 2 lots of private property on which private dwellings have been built.

It is planned to import approximately 42,000 tonne of aggregate from South east Queensland in Australia to Norfolk Island for the asphalt, concrete and ancillary requirements.

It is recognised that Norfolk Island is a unique habitat of flora and fauna and that it is necessary to manage all stages of the importation of sand and aggregate to minimize the risk of contamination with unwanted pathogens.

For technical reasons in the asphalt design, crusher dust will be sourced from Boral’s West Burleigh quarry while 7 mm, 10 mm and 14 mm size aggregate will be sourced from Boral’s Ormeau Quarry. The asphalt mix design would normally incorporate a washed pit sand, but to reduce biosecurity risk, a marine sand from Moreton Bay has been used in this mix design. The crusher dust from West Burleigh is needed to compliment the properties of the marine sand. For the concrete design, 32mm size aggregate from West Burleigh quarry and 20 mm size aggregate from Ormeau quarry are also required.

The process for getting the aggregate and sand from Brisbane to Norfolk Island will involve a number of elements. In outline, this includes transporting the sand and aggregate to a loading facility in Brisbane, loading a bulk ship, shipping to Norfolk Island in a bulk ship, transferring product from the bulk ship to a DO/DO barge at Norfolk island, landing the barge at a purpose built rock groyne, loading transport trucks on the barge and trucking the product to the construction site at the airport. The details of these elements along with the relevant biosecurity controls are covered in the following sections.

3 Process details for each product source 3.1 Lytton Marine Sand

Boral’s Lytton sand facility is located on the southern bank of the Brisbane River. It supplies a single product for a range of construction uses such as concrete, bedding, filters and asphalt.

The sand is sourced from Spitfire channel in Moreton Bay.

Spitfire channel

The sand is recovered by a combination suction dredge and barge. The sand is prescreened as it is loaded to remove any oversize contaminants. The barge has a load capacity of 3000 tonne.

The barge has dewatering pumps which allows the sand to drain on board. The loaded sand is transported to Boral’s sand facility at Lytton.

The sand is unloaded by a dedicated excavator on board the barge which places the sand in an onshore hopper. It is transferred from the hopper to shore by conveyor.

The sand is transferred from arrival stockpile to the storage stockpile by front end loader. After 2 days in the storage stockpile, it is available for end use delivery at approximately 6% moisture content. The source and process produce a sand of consistent quality and size.

Product destined for Norfolk Island will be loaded from a ”fresh” stockpile once the moisture content is below 6% and within 5 days of being transferred from the dredge. The test method and frequency for moisture measurement is included in the inspection and test plan.

This stockpile will be separate from older stockpiles to prevent product in longer term storage from mixing with the NI material

Two loaders are used on site but as there is only one product, their use is interchangeable. Where the loader has previously loaded product from other than the NI stockpile, the loader bucket will be checked to ensure it is free of sand or other contaminants and cleaned, if necessary, before loading from the NI stockpile.

The loader will only load from a minimum 200 mm above the stockpile floor to eliminate contamination from material other than sand.

The sand is loaded into trucks by frontend loader. The loads are then covered ready for transport. Dedicated trucks are primarily used to transport the sand but when there is a change of product, the truck bodies are checked for cleanliness and washed out prior to loading. Trucks go through a wheel wash and are subsequently weighed before dispatch.

3.2 West Burleigh Quarry, Crusher Dust and 32 mm

West Burleigh quarry is located at the Gold Coast south of Brisbane and supplies a variety of different sized quarry materials for civil construction. It consists of a metagraywacke metamorphic rock source.

The process first requires the stripping of vegetation and overburden material to expose clean quality rock. Once exposed the rock is drilled to provide core holes for filling with explosive. The location of the holes and quantity of explosive is calculated to produce fresh rock broken to size suitable for the crushing process.

The blasted rock is transported to the crushing plant in dedicated dump trucks. It is first processed in the jaw crusher (the primary) to break down oversize rock. The product exiting the jaw crusher can be scalped to remove any material passing a 40 mm screen if required. This will not be done for the NI material as the blast rock is from deep, pure, uncontaminated source rock. It then undergoes a series of screening and crushing processes through a large cone crusher (the secondary) and 3 smaller cone crushers (the tertiary stage) to provide aggregates of different sizes in discrete stockpiles. The discrete products are normally transferred by front-end loader and dedicated yard

trucks to the storage stockpiles. Products are sampled and tested for quality conformance from these stockpiles.

For Norfolk Island bound crusher dust, the product will be loaded from a “fresh” stockpile directly under the production belt. The product must be loaded within 2 days of production.

Where the loader has previously loaded product from other than the NI stockpile, the loader bucket will be checked to ensure it is free of other contaminants and cleaned if necessary, before loading from the NI stockpile.

The loader will only load from a minimum 200 mm above the stockpile floor to eliminate contamination from material other than crusher dust.

The shift will be dedicated to either 32 mm or crusher dust.

The crusher dust is loaded into trucks by frontend loader. The loads are then covered ready for transport. Truck bodies are checked for cleanliness and washed out prior to loading if required. Trucks go through a wheel wash and are subsequently weighed before dispatch.

3.3 Ormeau Quarry 7mm, 10mm, 14 mm and 20 mm

Boral’s Ormeau quarry is located between the Gold Coast and Brisbane and supplies a variety of different sized quarry materials for civil construction. It also consists of a metagraywacke metamorphic rock source.

The process first requires the stripping of vegetation and overburden material to expose clean quality rock. Once exposed the rock is drilled to provide core holes for filling with explosive. The location of the holes and quantity of explosive is calculated to produce fresh rock broken to size suitable for the crushing process.

The blasted rock is transported to the crushing plant in dedicated dump trucks.

It is first processed in the jaw crusher (the primary) to break down oversize rock. The product exiting the jaw crusher is scalped to remove any material passing a 40 mm screen. This removes soil or degraded material from the quality rock to be processed. The quality rock then undergoes a series of screening and crushing processes through the secondary and tertiary stage crushers to provide aggregates of different sizes which report to distinct stockpiles. Products are sampled and tested for quality conformance from these stockpiles.

Only one NI product will be loaded in a shift. The shift will be dedicated to only one of 20mm, 14 mm, 10 mm or 7 mm.

For Norfolk Island bound products, each product will be loaded from a “fresh” stockpile directly under the production belt. The product must be loaded within 2 days of production.

Where the loader has previously loaded product from other than the NI stockpile, the loader bucket will be checked to ensure it is free of other contaminants and cleaned if necessary, before loading from the NI stockpile.

The loader will only load from a minimum 200 mm above the stockpile floor to eliminate contamination from material other than the fresh screened rock.

The sized aggregates are loaded into trucks by frontend loader. The loads are then covered ready for transport. Truck bodies are checked for cleanliness and washed out prior to loading if required. Trucks go through a wheel wash and are subsequently weighed before dispatch.

4 Transport from Source to Pre-shipping Storage

All sand and aggregate will be transported in semi-trailer or truck and dog combination from the quarry source to either of:

(i) An enclosed storage area at 40 Steel Place Murarrie.

(ii) The Graincorp ship loading facility at Pinkenba.

All truck bodies will be inspected and cleaned, if necessary, prior to loading. All loads will be covered during transport and will taken directly from the source to the storage area.

5 Storage Prior to Shipping, Transshipment and Ship loading

There are number of factors that impact on the process of getting aggregate and sand from the quarry to the ship loader. These include:

(i) The need to transport material soon after production to minimise any possible contamination risk from storage within the quarry. (ii) The production rate achievable for each product component. (iii) The limited operating and transport hours permitted under the Development Approvals for each of the supply sites. (iv) The limited availability of suitable interim storage facilities in which any bioscecurity risks can be managed.

The process subsequently will involve a combination of delivery methods:

(i) The loading will be split over 2 bulk ships to allow accumulation of lower production rate product in the limited space, biosecurity acceptable, interim warehouse storage. (ii) High production aggregates and sand will be transported during daylight hours direct from the quarry to the ship loader. This transport will occur within the permitted operating hours for the supply sites. (iii) Lower production aggregates will be accumulated at the interim storage site for subsequent transshipment to the ship loader at night.

Storage

Sand and aggregate will be stored, in segregated stockpiles, undercover at a warehouse facility dedicated to Boral products only. This facility is at 40 Steel Place, Morningside. A preliminary inspection was conducted by a DAWR officer and the building deemed suitable, subject to agreed controls. Controls include:

(i) Identify and seal off external openings in the walls (e.g. pipe entry points) (ii) Thoroughly sweep and clean the interior prior to delivery of product. (iii) Sweep and clean the exterior traffic areas to prevent contamination on truck tyres (e.g. leaves and bird droppings). Implement ongoing monitoring and suction sweeping as required. (iv) After cleaning, apply an initial pesticide knock down spray and barrier spray. (v) Install a targeted baiting program, as per DAWR target requirements, document, and carry out inspections, and repeat application of ant baits, no less than fortnightly during the period of use. (vi) Reapply the perimeter barrier spray of deltamethrin at no greater than 6 weekly intervals. (vii) Provide a storage plan and Vehicle movement plan at the site.

A DAWR officer will inspect the storage immediately prior to delivery commencing and this will form a “Hold Point” require release by that DAWR officer.

Trucks will tip inside the building and the material will be pushed into stockpile by the front-end loader. A truck marshal will be on site to direct trucks and monitor the process for wind-blown contamination.

The capacity of the shed is such that the material will be spread over 2 shipments. The shed will be filled for the first shipment, emptied and refilled for the second shipment, with the building swept between shipments.

Transshipment

When the ship loading is ready to start, Boral will truck sand and aggregate direct from the production source during daylight hours to the open air receival hoppers at Graincorp. After hours, aggregate will be transshipped from the enclosed storage and tip at the open air receival hoppers at Graincorp. Trucks will be loaded from within the shed by font end loader. A truck Marshal will check the entering trucks to ensure:

(i) There is no contamination on truck wheels. (ii) The truck bodies are free from contamination

All trucks will be equipped with load covers for the 10 km journey from 40 Steel Place Morningside to Graincorp at Pinkenba.

Ship Loading

The open-air hopper area at Graincorp consists of a solid concrete floor with two separate hopper inlets. To limit contamination exposure, only the primary hopper at the SE corner of the area will be used. Trucks will be able to tip directly over the hopper or adjacent to it. The front-end loader will heap material over the hopper in the interval between trucks tipping. This process will be overseen by the truck marshal. This process should contain truck tipping to within an area 25 m x 25. The area consists of a substantial truck maneuvering area and concrete upstands at the load hopper inlets to limit material spillage.

The following actions will be taken prior to tipping material at the load point. A DAWR officer will inspect the tipping area for compliance and this will form a “Hold Point” in the ship loading process. (i) Groom the area and remove weeds. (ii) Provide screening or wrapping to trees which could be a contamination risk through loss of foliage. (iii) Install targeted ant baits prior to the commencement of loading. (iv) Thoroughly clean the area with a suction sweeper to remove any contamination. (v) Provide a truck marshal/spotter during unloading operations to record each truck arrival, direct the trucks where to tip, check the cleanliness of the wheels for truck entering the tipping area and monitor for wind-blown contamination. (vi) The truck marshal will work with the loader operator to limit exposure of material tipped at either hopper to a target of one hour with a maximum of two hours. Note the ship loader capacity is 800 tph with an expected max truck delivery rate of 360 tph.

In the event of a delay in the loading process (e.g. equipment failure) the following action will be taken: (i) The truck marshal at the ship loader will call the truck marshal at the truck loading point to suspend loading and hold all trucks. (ii) At the ship loader, the front-end loader operator will push any tipped material into stockpiles over the load hoppers. (iii) If the delay will exceed one hour, the loader driver and truck marshal will cover the stockpile with a tarp. Two tarps will be at site, ready to be deployed, in the event of this contingency.

After loading into the ground level hopper, the material will travel via an inclined conveyor direct to the each of the ships holds. The loading process can deliver 800 tonne per hour but will be limited by the truck delivery process to a maximum of 360 tonne per hour.

Graincorp’s “Export Hygiene Biosecurity Process” will apply and targeted ant baiting will take place for 2 weeks prior to the commencement of loading.

6 Fumigation of Aggregate and Sand in the Ship’s Holds.

The following process has been mandated by DAWR.

The consignment must be fumigated with methyl bromide at 48 g/m3 for 24 hours at or above 21 degrees C. A fumigation certificate must be provided to the department prior to the goods arriving in Norfolk Island. Notes:

(a) Fumigation must be performed immediately prior to loading or in the ship’s hold (b) For each 5ºC (or part of 5ºC) the temperature is expected to fall below 21ºC, 8g/m³ must be added to the dosage rate. (c) Methyl bromide fumigation is not permitted if the ambient minimum temperature falls below 10ºC. (d) A fumigation plan must be provided to the department for approval prior to commencement of the treatment.

The specific fumigation plan requires finalisation of the ship charter and has to be agreed with the fumigator, the ship’s owner/captain and the port authority. It can be provided prior to the process being carried out, but is not available for inclusion with this plan.

Rentokil’s SOP for Methyl Bromide Fumigation in the ship’s hold is provided as an attachment.

7 Sampling and Testing for Phytophthora Cinnanomi

Phytophthora Cinnanomi (root rot) has been identified as the primary pathogen of concern for the importation of aggregate to Norfolk Island.

Testing for Phytophthora cinnanomi can be conducted by “Grow Help” within the Department of Agriculture and Fisheries, Queensland State Government. https://www.business.qld.gov.au/industries/farms-fishing-forestry/agriculture/agribusiness/grow- help-australia/submitting-samples

Boral collected baseline samples from each material source on the 9th and 11th of April 2019 and delivered these samples, sealed in plastic bags, to “Grow Help” on 15th April 2019.

The test results were clear and are provided at the end of this appendix.

In addition, at the direction of DAWR, the Queensland Department of Agriculture & Fisheries (QDAF) was engaged by Boral to conduct wide area sampling of the perimeter at both West Burleigh & Ormeau quarries. The basis of this was, that if no Phytophthora cinnanomi was present surrounding the quarry, and in areas that stormwater ingress was possible, then the risk of subsequent contamination of the stockpiles within the quarry was considered extremely low. This risk was mitigated even further by limiting storage within the quarry to a maximum of 2 days.

GDAF’s report, prepared by Dr Andrew Manners is provided as an attachment.

8 Shipping

The aggregates will be transported by two charter vessels in bulk holds. The vessels will have a capacity of 35,000 tonne total in 5 separate holds. The cargo tonnage will be split approximately evenly between the two ships for a total of 42,000 tonne.

Example ship only. Actual ship subject is to charter availability.

Each bulk ship will load at the GrainCorp facility at Pinkenba on the Brisbane River. Each ship’s hold will be clean and free of any foreign matter. The holds will be inspected by a qualified marine surveyor prior to loading and found free of live insects and extraneous materials that pose a

phytosanitary or sanitary risk. The ship’s officer will also provide details of the previous 5 cargos to the marine surveyor. A marine surveyor’s certificate must be issued prior loading. The surveyor’s certification will also cover the cleanliness of the front-end loader, the receival hopper and conveyor system. This certification will be a “hold point” in the loading process.

Example Cargo Plan only.

9 Unloading at Norfolk Island

The charter ship will moor off Ball Bay at Norfolk Island. Aggregates and sand will be transferred from the bulk ship to a flat deck barge via clam buckets attached to the ship’s cranes. Procedures will be in place to minimise any spillage of material, particularly sand, during the transfer process. The procedure will also cover controls applicable to transport vehicles. The procedure is provided separately as an attachment. The barge will transfer the cargo from the bulk ship to a specially constructed groyne in Ball Bay. An excavator on the barge will load the sand & aggregate to both local and imported trucks which will deliver the cargo to the airport. The groyne will be constructed in advance from local materials in Ball Bay.

Proposed Ship mooring and groyne location.

The tug & barge will establish in advance of the bulk ship. The barge will establish from Vanuatu and will not carry any cargo to Norfolk Island.

Typical barge & groyne from previous project. Ball Bay with groyne.

It is planned for the barge to load from the ship at night and for the barge unloading and transport to occur in daylight hours. 10 Airport Storage

Aggregate & sand will only be stored within the airport precinct and at two locations. The primary storage pad at the airport for sand & aggregate will be the SW end of the asphalted cross runway 04- 22. The working storage pads at the asphalt plant will be covered in a waterproof bitumen/chip seal. The primary purpose is to prevent the imported material being contaminated by local soil, but it will serve the dual purpose of preventing the contamination of local soil from the highly unlikely risk, due to biosecurity controls, of contamination by an imported pathogen.

B. Testing for Phytophthora Cinnanomi

Baseline testing of existing stockpiles was undertaken to identify if phytophthora cinnanomi might be present in existing processes.

Sampling was carried out as recommend by “Grow Help” within the Department of Agriculture and Fisheries, Queensland State Government. The process involved:

• Taking 6 sample portions from around the stockpile. • For each sample portion, removing at least 200 mm of surface material and taking a scoop of uncovered material. • Accumulating 6 sample portions in a new and clean plastic sample bag to form a representative sample for each stockpile. • Sealing the plastic bag. • Labelling the plastic bag with ID and date.

Identification of the baseline samples is as follows:

• Sample 1. Lytton Sand, sampled from plant stockpile 9/4/19. • Sample 2. West Burleigh crusher dust, sampled from quarry 11/4/19 • Sample 3. Ormeau 7 mm, sampled from quarry 11/4/19

Site Perimeter Testing

At the direction of DAWR, the Queensland Department of Agriculture & Fisheries (QDAF) was engaged to conduct wide area sampling at both West Burleigh & Ormeau quarries. The basis of this was, that if no phytophthora cinnanomi was present surrounding the quarry, and in areas that stormwater ingress was possible, then the risk of subsequent contamination of the stockpiles within the quarry was considered extremely low. This risk was mitigated even further by limiting storage within the quarry to a maximum of 2 days.

7. Method of Work

GENERAL INSTRUCTIONS / DETAILS It is your responsibility to ensure that you understand this procedure before performing the following tasks. Contact the document author if you have any questions about this procedure as well as all associated requirements in relation to IMDG CODE (International Maritime Dangerous Goods Code) 2008 Edition Supplement – “Recommendations on the Safe Use of Pesticides in Ships applicable to the Fumigation of Ships Holds. A full assessment of venting/air intake inlets and air-conditioning system (including sanitary vents, galley vents and engine room ventilators) must be undertaken for all manned areas (including crews quarters) by the ‘Fumigator-in- Charge’ and written instruction must be provided to the Master/Captain (before ship sets sail) on requirements for ‘shut-down’ during the ventilation process. The ‘Fumigator-in Charge’ must undertake a thorough inspection of the vessel, and all potential leakage areas must be identified following visual inspection. Physical testing to ensure that holds are structurally sound should have been conducted prior to loading of the vessel by an authorised party (records to be provided). Placarding – The fumigator must provide and erect appropriate placards for methyl bromide immediately prior to fumigation. Placards must be used for the purpose of providing a warning sign for holds/areas under fumigation. Placarding will also be placed in engine rooms in the vicinity of cargo hold bilge valves/piping as applicable, so that no accidental gassing can occur. The placards must comply with the IMO requirements for Placarding, and must also contain any additional requirements outlined by AMSA. The placard must also contain a subsidiary risk pictogram of ‘Flammable Gas’. Placards must remain in place for the entire duration of the voyage and may not be taken down until all residues have been removed from the ships holds. The vessels agent shall notify persons intending to visit the vessel that fumigation will be taking place on board and access may be restricted. This would include for example, stevedores, wharf personnel, contractors, surveyors, and Government Officials and the like. It is also advised that the expected timeframe of restriction should be included in any notification. A watchman must be placed at the gangway and shall not allow unauthorised persons on board whilst the fumigation process takes place. Clear instructions on his/her responsibilities with regard to this duty need to be provided by the Master/Captain and the ‘Fumigator-in-Charge’ as appropriate. It is also recommended that the vessels crew, where possible, remain indoors during this process.

The following is too preformed for ship fumigations with Methyl Bromide: Preparation • Inspection – inspection of all holds, access ways and connected areas. Special attention is to be taken to the bulge areas of the ship or any connected areas to the engine room/s • Sealing of hatches – hatches, hold vent points and access points will be sealed with cloth tape to ensure there are no gas leaks

• Circulation Ducting – ducting is to be placed down the hold via the man entry points (where possible / or close to) to aid in circulation and venting of the fumigation. A circulation fan is connected to the ducting blowing into the holds • Installation of introduction / monitoring lines – gas introduction lines should be placed as close as possible to the top of the commodity being treated (facing the top of the hold) as the gas will sink to the bottom of the hold during the treatment process. Monitoring lines should be placed (a minimum of 2 per hold) at the top of the commodity and as close to the bottom as possible. • Sealing of holds – the seals must be checked and cleaned if required to ensure a tight fit with the hold cover. Any joining points must be sealed with cloth tape to ensure a gas seal. • Sealing of access points and connected areas – all connected areas and access points to the holds must be sealed to prevent access and possible leakage out of the treated holds. It is recommended to check with the vessels engineer to verify any connected areas • Seal checks – check to ensure that all gaps have been sealed. Equipment • Gas masks and gas dispensers must be checked to ensure all are in working order. DURING ALL USE OF METHYL BROMIDE A FULL FACE MASK MUST BE WORN AT ALL TIMES WITHIN THE RISK AREA Fumigation • Introduction of the methyl bromide into the hold must be done at a steady rate • Pipes delivering the methyl bromide must be inserted just below the hatches to enable the gas to drop through the product • 2 monitoring point must be placed below and away from the pipes (being used to administer the methyl bromide) to confirm the gas has dispersed. Rate • Methyl bromide must be administered in accordance with the conditions specified on the import permit

Monitoring the Fumigation • Seals, hatches and the risk area – once the full amount of methyl bromide have been introduced into the hold all seals must be rechecked for leaks, (using a methyl bromide gas detector). MONITORING MUST BE UNDERTAKEN AT 30MINS FOLLOWING THE INTRODUCTION OF THE METHYL BROMIDE TO ENSURE THE CORRECT AMOUNT OF GAS HAS BEEN INTRODUCED INTO THE HOLD • If the methyl bromide concentration is at the required rate and within the desired equilibrium range the fumigation proceeds as normal • If the concentration is low the hold must be rechecked for leaks and additional gas will need to be introduced. 4 Hour Check • At the 4 hour mark the holds and risk area must be checked for leaks • The hold must also be checked to ensure the correct gas concentration is beeing maintained. MONITOR HOLDS AT REGULAR INTERVALS TO ENSURE GAS RETENTION • The hold must be monitored at regular intervals to confirm the methyl bromide concentration is adequate. • The risk area, connected areas and hold must also be checked for leaks • All areas regularly visited by personnel (accommodation areas, engine room, bridge and any other areas) must also be checked at regular intervals for leaks and gas concentrations. • All areas of treatment and those mentioned above must be checked at regular intervals throughout the treatment process (no more than 4 hours between checks). Final Readings • 24 hours after the introduction of the gas the final readings must be taken and recorded to confirm that the importing country requirements have been met.

• If the requirement has been met the venting process can commence. • If the requirements have not been met the hold must be topped up and treated for an additional 4 hours. Venting • To commence venting remove all tape sealing from the holds, vents and access covers. • Turn on the circulation / ventilation system to increase air movement within the hold • Crack the first hold to allow the gas to start to escape at a controlled rate • After a few minutes the hold must be completely opened to facilitate the venting process • Only open one hold at a time to minimise the risk of high concentrations of gas escaping at one time. • During venting personnel is to be kept minimised, all risk areas are to remain in place and anybody entering the treatment area must be wearing an appropriate mask and filter and be accompanied by a licenced fumigator. Confirming gas clearance • The monitoring frequency of the gas levels within the hold and the risk area will be dependent on the weather conditions • Gas freedom is achieved when levels of 5ppm or lower is reached, this may take anywhere from 12 to 24 hours depending on the weather and prevailing winds. • Once the fumigator has confirmed that the hold is gas free the fumigator issues the gas free certificate and can issue the fumigation certificate.

If the SOP is unable to be followed a secondary Risk Assessment, Safe Work Method Statement, and Specialised Standard Operating Procedure must be created and approved by management.

Job Completion 1. Advise the office of the final monitoring readings as well as the gas clearance readings. 2. Inform the yard the job is complete and sign off in their relevant job book. 3. Ensure the site is clean and tide when you leave. 4. Record all gas mask filter use as well as updating your personal treatment diary.

1 General Overview

Boral Resources (Qld) Pty Limited has been contracted to upgrade the runway on Norfolk Island Airport. This will involve installing approximately 30,000 tonne of asphalt over the existing runway pavements, providing concrete parking aprons for aircraft, replacement of existing Airfield Ground Lighting (AGL), regrading of runway flanks and new line-marking.

There is a limited amount of suitable construction equipment on island to carry out the proposed works and the majority of plant and equipment required for the project will be imported specifically for the works. With the exception of some small equipment, all equipment will be returned to Brisbane, Australia on completion.

There is no wharf infrastructure on Norfolk Island. The project involves the construction of a groyne out into the sea at Ball Bay. Equipment will be shipped on a towed barge fitted with DO/DO bow ramp. 3 barge voyages will be required to establish all the required equipment & stores.

Ball Bay is approved by DAWR for the discharge of petroleum fuel and LPG only. Boral will make an “Application for Permission to Unload Goods at a Landing Place or Port other than a First Point of Entry”, once DAWR have accepted this Biosecurity Plan.

The biosecurity inspection resources on Norfolk Island are limited and there are no facilities for large scale equipment cleaning or fumigation.

Equipment to be shipped includes a mobile asphalt manufacturing plant, a mobile concrete batching plant, tip trucks, concrete agitators and a variety of specialised construction plant.

The planned method of biosecurity control is to clean, fumigate or otherwise treat equipment and stores here in Australia, prior to departure for Norfolk Island. This will significantly reduce the level of inspection required on arrival at Norfolk Island and eliminate the need for local cleaning and treatment, except where minor conformances, if any, are detected.

3 Cargo Reporting

A cargo manifest will be prepared for each voyage. The cargo for each voyage will be planned well in advance and the cargo manifest prepared. Due to the nature of the project, the range of specialist contractors, and the wide range of stores and specialised equipment, the completed actual cargo on any voyage will not be finalised until each barge departs.

The completed manifest will be available and distributed within 48 hours of departure of the barge.

A copy of the manifest will be emailed to the biosecurity officer on Norfolk Island. As the transit time of the barge is 8 days, the officer will receive this information at least 6 days before the arrival of the barge at Ball Bay.

The cargo manifest will be in the form of an excel spreadsheet. It will contain at least the following information:

(i) A list number for each item of cargo. (ii) Containerised items, listed individually, but grouped by container ID (iii) Unique identifier for major items (e.g. vehicle VIN or rego number) (iv) Weights and dimensions for major items. (v) Reference to the unique cleaning inspection seal number for used equipment. (vi) Reference to invoices or other providence documents for new equipment. (vii) Owner’s name (some goods will be the property of NIRC or local residents) (viii) Reference to fumigation certificates where appropriate (e.g. containerised goods) (ix) Reference to insecticide application report on loading.

Note that the DAWR Inspection Group in Brisbane will maintain a register of all equipment inspected by them. This will have a description of the equipment, VIN identification number or similar, if applicable, and the unique number of the seal attached by them, to the equipment, on completion of satisfactory inspection. The DAWR Inspection Group will provide regular updates of the register to the Biosecurity Officer on Norfolk Island and Boral’s Logistics Coordinator.

4 Used Equipment Cleaning.

Used equipment will be cleaned to a standard acceptable to the DAWR inspection officers, Inspection Group, DAWR, Port of Brisbane.

The equipment will be pre-cleaned by Boral to remove obvious external contaminants. It will then be transported to Chalmers Industries Pty Ltd at the Port of Brisbane for cleaning to biosecurity import standard at Chalmers’ approved cleaning station.

Boral will provide Chalmers with a list of equipment and order of cleaning, regularly updated, and coordinate delivery of equipment to suit storage available, and the rate at which equipment can be cleaned & inspected.

Chalmers will carry out the cleaning and coordinate the inspection process with the Inspection Group, ensuring notice is provided and inspections are booked.

The Inspection Group will maintain a register of equipment cleaned, based on Boral’s equipment list.

Once a piece of equipment has been cleaned and approved, the Inspection Group will fit a uniquely numbered seal to a conspicuous location on that equipment.

The register will then be updated with the seal number, date inspected, DAWR identifier for the inspector, and the inspector’s comments, if required.

Regular updates of the cleaning register will be forwarded to the biosecurity officer on Norfolk Island.

Once tagged with a seal, the equipment will be moved to Chalmers’ nearby, surface-sealed hardstand area for storage awaiting loading on the barge. Storage times will vary, but could be up to 6 weeks.

Boral will undertake weekly inspection of stored equipment and maintain a record of those inspections, any non-conformances found and the action taken.

5 New Equipment

There will be some new equipment purchased specifically for the project or supplied to NIRC as part of the contract arrangement.

New equipment will be sent to Chalmers for cleaning and inspection. It will subsequently be delivered to the loading staging area at 50 Paringa Road, Murarrie within 2 days of loading. Boral will inspect the equipment for possible contamination prior to loading and clean as necessary. Inspection Services will be advised of the availability of the new equipment for inspection and will inspect at their discretion.

New equipment will receive the pest control treatment as per item 9.

New equipment will be supported by invoices or other providence documents. Verification can be made from the odometer or hour meter on the equipment.

6 Containerised Stores

Bitumen & Cement will be transported in dedicated, material specific sea containers. These containers will be visually internally inspected prior to loading for residual product or contamination. Unsuitable containers will be rejected. Note that this is driven by the material quality requirements of the project and not biosecurity alone.

The following treatment will apply to bitumen containers:

(i) On arrival at the staging location, the containers receive a pressure wash and the underside of the container will be inspected and pressure washed while on the side- loader. (ii) The containers will be unloaded onto timbers above the sealed pavement. (iii) The hollow burner tubes will then be treated with Chandrite spray and Maki Block Rodenticide before being sealed with a cover plate. (iv) Prior to loading on the barge, each bitumen container will be picked up from the staging area and put on the inspection stand. (v) Boral will inspect and spray any insects found with a fast knockdown aerosol (vi) Boral will dry vacuum the underside of all containers (vi) Inspection Services will then inspect the containers, if they elect to attend. (vii) The pest controller will treat the underside of all containers with deltamethrin. (viii) The container will be moved from the inspection stand to the barge. (ix) Records will include a photograph of each container on the stand and a pest treatment report for each bitumen container.

The following treatment will apply to cement containers:

(x) The cement containers consist of a hollow frame (no floor) with an internal pressure tank and all surfaces are accessible. (xi) On arrival at the staging location, the containers receive a pressure wash while on the side loader. (xii) The cement containers will receive further inspection onloading and insecticide treatment as per section 9. (xiii) The cement containers will receive treatment with deltamethrin to all pin sockets.

General stores and spare parts will be loaded into standard sea containers. These items will be mainly new, but there may be some reconditioned spares. These containers will be internally fumigated at Chalmers’ approved facility at POB using Methyl Bromide.

Where appropriate, containers housing sensitive electrical equipment will not be fumigated with Methyl Bromide. An alternative fumigant (such as sulfuryl flouride) or topical pesticide (such as deltamethrin) will be used.

The fumigator used by Chalmers is Blufume Pest Control (DAWR registration no: Q2805).

Fumigation certificates for each container will be referenced on the cargo manifest. Copies will be available to DAWR if requested.

7 Accumulation Storage and Storage Prior to Loading

Equipment that is new, or cleaned and approved by Inspection Services, along with containerised materials & supplies, will be stored in Chalmers storage yard at the Port of Brisbane. The storage yard is immediately across the road from the cleaning pad.

The storage location is primarily a shipping container storage area. It is situated on a fenced and secure asphalt hardstand with good separation from the limited landscaping vegetation at POB.

Boral will conduct weekly inspections of the cleaned equipment in the storage area. Records will be kept of these inspections. Where a nonconformance is found, action will be taken and also recorded. If specialised treatment is required (e.g. pest treatment), relevant documentation will be provided (e.g. pest treatment certificates).

A section will be set aside for the storage of Boral barge cargo only. The cargo held for Boral will not be mixed with other cargo.

The Chalmers’ yard will be the location for accumulating and staging each barge cargo. The Storage area is a dedicated export area with sealed hardstand and separation from vegetation. A pest control and baiting program is in operation at each of Chalmer’s facilities and implemented by Blufume Pest Control.

Two days before the loading of the barge commences, Boral will commence transferring cargo from Chalmers yard at POB to the Pacific Tug yard at 50 Paringa Road, Murarrie. A bitumen sealed hardstand area leading directly to the RO/RO ramp of the barge has been prepared for this purpose. This process is necessary to accommodate over-dimension equipment which can only be moved under time-restricted permit, and to allow for efficient barge loading. Some cargo will be staged short term at the Pacific Tug yard and some will travel direct from Chalmers’ yard onto the barge.

A pest control and baiting program is in operation at the Pacific Tug sealed hardstand at Murarrie.

Primary Storage Point and Barge Loading Point

8 Loading the Barge

10 days prior to the planned loading of the barge, Boral will provide a copy of the proposed manifest to Inspection Services for reconciliation with their inspection records.

Prior to loading the barge, there will be a HOLD POINT. Boral will provide relevant documentation to confirm:

a. All new equipment has been inspected by the department, or Boral, must be clean and free from animal and plant material and soil, and if cleaned, are accompanied by documentation stating the method of cleaning. b. All used equipment must have been inspected by the department, and cleanliness maintained by Boral, to ensure the conditions of section 37 of the Biosecurity (Prohibited and Conditionally Non-prohibited Goods – Norfolk Island) Determination 2016 are met on arrival in Norfolk Island. c. Other equipment, such as but not limited to general purposes containers, concrete containers, concrete bollards, but excluding bitumen containers, must be clean and free from animal and plant material and soil, and if cleaned, are accompanied by documentation stating the method of cleaning.

Bitumen containers will be treated in accordance with the BMP immediately prior to loading, but will not be loaded until the hold point release has been met for all other cargo. The conformance report for bitumen container inspection & treatment will be provided within 24 hrs of treatment and loading.

Prior to loading the barge, the deck of the barge will be swept clean and washed with potable water if required.

Everything loaded onto the barge will receive an external inspection immediately prior to loading. This is to identify any contamination that may have occurred to new or precleaned equipment during recent storage. A blower/vacuum and pressure water sprayer will be on hand to address minor contamination from the storage process. If major contamination is found, the equipment will be moved back in the queue for more thorough inspection and cleaning.

As stores and equipment are driven onto the barge via the bow loading ramp, a high-pressure water sprayer will be used to wash the vehicle wheels.

At this point, the underside of containers will be accessible through the truck frame and will also be pressure washed.

For containers, locking pins will be welded to the deck in advance of loading and the area cleaned of welding waste prior to loading.

For heavy equipment, the load restraint anchors will be welded to the deck after the equipment is in its transport location. Welding waste will be vacuumed up after load restraint is complete.

During the loading process for the barge, all equipment and containers will be treated with a residual insecticide, deltamethrin or approved equivalent. This treatment will be carried out by Blufume Pest Control (DAWR registration no: Q2805).

It is not proposed to fully coat all surfaces. Surfaces will be selectively sprayed where insects might nest or traverse surfaces. Containers will be sprayed in the container lock recesses or other susceptible locations.

Fixed installations on the barge deck will also be treated such as anchor winches and hydraulic power packs.

The Pest Controller will mark off each item treated form a cargo list. On completion, the pest controller will provide a certificate for the treatment carried out and attached the hand notated hardcopy of the cargo list. The MSDS for the product used, together with the manufacturer and batch number will be provided with the report for spray treatment.

10 Supporting Documentation

The following supporting information will be available for biosecurity officers on Norfolk Island in the form of a conformance report:

(1) The cargo manifests (2) Inspection Service’s cleaning register (3) Fumigation certificates for relevant containers (4) Invoices or other evidence for new equipment (5) Pest Treatment reports (6) Photographs where nominated (7) Records of all inspections carried out by Boral, including any nonconformances found and actions taken.

Boral will also provide a copy of this conformance report to Tim Killesteyn ,Assistant Director, Cargo Operational Policy, DAWR.

Notwithstanding the preparation of the conformance report, individual pest control reports and fumigation certificates will be sent to [email protected] prior to loading the barge.

11 Contingency Arrangements on Norfolk Island

On landing the barge at Norfolk Island, the barge will be inspected by the Operations Manager, Inspection Services, DAWR on Norfolk Island. If major contamination is found, the cargo or partial cargo may not be allowed ashore. In the event of minor contamination, the Operations Manager may direct specific cleaning or pest treatment.

There are no specific biosecurity facilities on Norfolk Island. There is a quarantine shed that is only suitable for smaller items. Boral will have high-pressure water cleaning equipment on the barge and can address minor contamination on the barge if required.

As all equipment will be going to the airport precinct, it will be possible to isolate specific items at the end of the cross runway on a sealed pavement. The goods would not be under cover.

Boral has had engagement with Ron van Gorth, a licensed pest controller for both deltamethrin spraying and Methyl Bromide fumigation operating on Norfolk Island. There are no DAWR registered pest controllers on Norfolk Island. Treatment can be effected on the barge or at the isolation area at the end of the cross runway if required.

12 Unloading on Norfolk Island

When the barge arrives at Norfolk Island, only those personnel necessary to facilitate the mooring of the barge and the landing of the access ramp will be allowed on the barge prior to inspection by DAWR officers.

DAWR officers will do an initial inspection of the cargo, and if satisfied the cargo and condition is consistent with the documentation, will allow unloading of the barge to commence. DAWR officers may elected to do further inspection at any time during the cargo unloading.

Cargo unloading will be during daylight hours, nominally in summer between 5.30 am and 8.00 pm (0530 to 2000) to allow inspection, if elected, by DAWR officers.
