Biodiversity Management

  • During clearing activities vegetation shall be cleared separately and stockpiled adjacent to the cleared area to facilitate re-spreading. Vegetation clearing should avoid damage to adjacent live vegetation.

  • Ensure that vegetation clearing protocols include appropriately stock-piling cleared vegetation, topsoil and trench spoil to facilitate rehabilitation.

  • Clearing and stockpiling will only be undertaken within the specified construction footprint, and clearing boundaries will be delineated prior to clear and grade activities being undertaken.

  • Spiecapag will develop a Vegetation Clearing Procedure prior to commencing construction that describes best practice vegetation clearing procedures to minimise harm to wildlife during land clearing activities.

  • The trench will be progressively backfilled after the pipe is installed.

Biosecurity

Clean Areas

  • Induct staff on the identification and reporting of weeds during site inductions. Workers and contractors to report suspected weeds to Environmental Manager immediately.

  • Review and develop mapping of weed management zones and weed hygiene stations. Weed hygiene stations are to be used and inspections undertaken between weed zones and at additional sites as determined prior to reinstatement. Weed hygiene declaration forms are to be completed for each inspection.

  • A weed identification booklet for the weed species known to occur within the construction footprint will be available to staff. Fact sheets will be displayed at camps and in crib huts.

  • A weed identification booklet for the weed species known to occur within the construction footprint will be available to staff. Fact sheets will be displayed at camps and in crib huts.

  • Stockpile weed infested vegetation and topsoil separately to vegetation and topsoil that is free of weeds; do not move soil between weed zones.

  • Install weed hygiene points at required locations, and enforce the use of weed hygiene stations.

  • Personnel working in high weed risk zones will also be subject to weed hygiene, specifically checking boots and clothes for seeds prior to moving between weed zones or into ‘clean’ areas. Operators will be trained in this as part of the weed inspection training.

  • Only vehicles and machinery approved for clearing works will access weed risk zones. All general construction traffic and machinery will only travel on ‘clean’ work areas. All vehicles and machinery must have a valid vehicle and machinery weed hygiene declaration.

  • If required undertake control of weed populations (either by chemical or physical means) for small infestations or where new infestations are identified within the construction footprint (‘clean’ areas). Controls to be implemented by suitably qualified workers in accordance with Qld guidelines, or Statutory Weed Management Plan.

Reinstatement/rehabilitation activities

  • Construction footprint will be progressively reinstated.

  • Undertake chemical control of weed populations in identified control zones along the construction ROW, within topsoil stockpiles, and along access tracks, prior to undertaking rehabilitation works, as required. Controls to be implemented by suitably qualified workers in accordance with Qld guidelines, or Statutory Weed Management Plan.

  • Replace removed topsoil and cleared vegetation back to original location. No topsoil or vegetation is to move between weed zones.

  • Any active revegetation (i.e. seeding or planting) must not use declared weed species.

  • No contaminated washdown water will be discharged to watercourses

  • Induct staff on the identification and reporting of weeds during site inductions. Relevant operators should be trained in weed inspections.

Vehicle Washdown

  • A washdown bay will be established at the camp/laydown yard for the duration of the project

  • Temporary washdown/blowdown weed hygiene locations will be established at all required locations as described in the Weed Management Plan.

  • Washdown pads for vehicles will be constructed to capture and recycle wastewater. No discharge of contaminated water will occur from washdown bays.

  • All washdown bays will be bunded to capture run-off

  • Washdown facilities will capture weed seeds in a sump to ensure they are not spread to surrounding environment.

  • Sump residue will be removed and disposed of at a licenced facility.

Fauna Protection

  • For safety reasons, FSCs will not be permitted to enter the trench. Entry to the trench to check fauna shelters will only be permitted with the approval of a Health and Safety Manager and will be in the presence of an identified observer whilst no construction works are being undertaken in the vicinity.

  • Undertake trenching and backfilling in a progressive manner that minimises the length of trench open.

  • Install end caps on welded pipeline strings at the end of the day’s construction activities to stop fauna becoming trapped.

  • Install earth plugs with slopes less than 45° (to provide exit ramps for fauna) at intervals of no greater than 1km intervals to allow the passage of fauna and stock.

  • Provide fauna shelters at 500m intervals along open sections of trench to provide shade for any fauna within the trench.

  • In the section of the construction ROW between KP 609.5 and KP 622 (i.e. suitable Carpentarian Antechinus habitat), for every 50m of rocky habitat and every 100m of intervening habitat, hessian (or similar material) will be draped from the top of one side of the trench, down along the side and bottom of the trench, and up the other side to the top of the opposite side of the trench

  • Maintain a Fauna Incident Log that records any animal death or injury due to any construction activity (apart from land clearing and trenching) – e.g. vehicle strike.

  • Prepare a Trench Inspection Report (Daily Enviro Report) - For each trench inspection (i.e. daily), records the KP’s surveyed, number and species of fauna relocated or deceased, locations in which release occurred, and recommendations.

Daily Trench Inspections

  • The maximum length of the open trench will not exceed the length capable of being practically inspected and cleared by FSC teams

  • Each day, prior to commencement of works, the FSCs will inspect the trenches for fauna. The trench inspections will be scheduled and resourced so that they can be completed within five hours of sunrise each day. The number of FSCs will be adjusted as required to achieve this target

  • Trench inspections will be conducted from the end of the trench closest to where works will be commencing, towards the other trench end.

  • Trench inspections will be completed by FSCs walking along the edge of the open trench and making observations using suitable methodologies such as a mirror attached to a pole. This will ensure that all areas of the open trench (including base and walls) are inspected

  • Any detected fauna will be captured using suitable methodologies such as a modified pool-cleaning net to enable capture without the FSC entering the trench.

  • If fauna is detected within the trench during construction works, then any works within the area which a FSC believes could impact the animal will cease.

  • Fauna that are removed from the trench will be assessed for any injury, and uninjured animals will be immediately released into adjacent suitable habitats. The FSCs will be suitably qualified to assess the habitat requirements of each species so that they are released in areas where their survival potential is maximised.

  • In the event that the immediately adjacent habitat areas are deemed unsuitable for release of an animal, it will be temporarily contained in a catch bag and placed in a cool dry area until a suitable release site is identified.

Hot Spot Inspections

  • Any recorded incidence of a listed threatened species.

  • Higher than average numbers of small mammals and frogs, that are most susceptible to mortality by desiccation or are trapped in a designated section of trench on a daily basis.

Construction Trench Inspection

  • A FSC will be responsible for assessing the situation and removing the animal by the most appropriate means.

  • Works will resume once the FSC indicates there is no longer a risk of impact to fauna from construction works.

Reinstatement and Rehabilitation

General

  • Progressive reinstatement of ROW must commence within 6 months of completion of construction activities.

  • Construction ROW and all temporary facilities, tracks and work areas will be progressively reinstated the construction phase. The entire construction footprint is to be reinstated, unless permanent access is required or landholders request that certain infrastructure remains.

Right of Way

  • Trench is to be backfilled and topsoil respread along construction ROW within 3 months of construction.

  • Topsoil is to be respread across the disturbed area, in the same location that it was originally cleared from.

  • Topsoil must be the final ground cover layer, as it contains the seed stock.

  • Any contaminated land resulting from construction activities is remediated.

  • Vegetation cleared during the ROW construction will be spread back over topsoil as a ground cover.

  • All waste materials are removed from ROW, including flagging used to delineate sensitive environmental areas, cultural heritage areas or weed management zones.

Watercourse crossings

  • Minimise the duration of disturbance by progressively reinstating watercourse crossings as soon as practicable following construction of crossing, including access through water courses when no longer required.

  • Major watercourse crossing profiles will be surveyed for levels prior to disturbance and these levels will be used as a guide for reinstatement following construction.

  • Bed and banks of watercourses will be reinstated to pre-disturbance conditions.

  • Active revegetation of watercourse banks will be considered to minimise vegetation fragmentation and assist in rapid stabilisation.

Erosion and Sediment Control

  • Permanent drainage controls are installed in accordance with the ESCP. As a minimum, diversion bunds will be installed at intervals along the ROW and at approaches to watercourses to avoid water flowing down the ROW, into watercourses and resulting in erosion, and sedimentation of watercourses.

  • Temporary drainage, erosion and sediment controls will be installed and maintained in accordance with ESCP to assist in diversion, stabilisation and management of anticipated surface water flows during site re-establishment; these will be removed once there is sufficient ground cover for the area to be stable (to be detailed in ESCP).

  • Permanent erosion controls will focus on ground cover in the form of natural revegetation.

Weed Management

  • Rehabilitation monitoring and maintenance includes weed control where required.

  • Implement Weed Management Plan, specifically weed management zones, weed hygiene and restrictions on moving weed contaminated vegetation and topsoil along the ROW.

  • Operators and staff working on reinstatement will be trained in weed hygiene and weed inspections, and will adhere to weed management zones and required controls.

Temporary Infrastructure

  • All temporary infrastructure will be reinstated as follows: infrastructure removed, topsoil respread over the surface, recontoured to match the surrounding landscape, ripped along the contour, and cleared vegetation will be respread as ground cover to aid in revegetation.

  • All temporary construction infrastructure (access tracks, construction camps and water storage dams) will be decommissioned and reinstated unless otherwise requested by the Landholder.

  • Temporary construction camps will be constructed, used, and decommissioned progressively as construction moves along the ROW. As each camp is no longer required all infrastructure will be removed (and moved to the next camp location for reuse where required). Where possible, habitat trees will be retained at construction camps (i.e. not cleared initially) to aid in rehabilitation and stabilising the landform.

  • Dams will be dewatered where required; any dams that require dewatering will first be sampled and analysed for potential pollutants, prior to dewatering to land via erosion and sediment controls as per ESCP.

  • Dams will then be backfilled, returning soils in the order that they were removed.

  • Temporary access roads will be reinstated once once construction is complete unless required by landholder. Permanent diversion bunds and drainage may be installed along the access track to shed water and avoid erosion down the track; to be detailed in ESCP.

  • The construction ROW will not be actively revegetated but will rely on the natural seed stock in topsoil and cleared vegetation. Measures will be implemented to manage trees from growing over the pipeline (refer following section).

Permanent Infrastructure

  • Permanent access points will be required for maintenance activities and to access the MLVs and CPs. Any permanent access will be managed via landholder agreements and Jemena will be responsible for ongoing monitoring and maintenance of these areas (refer following section)

  • Pre-construction land use will be reinstated as much as possible, including repairing pastoral fences and gates, and minimising risks to livestock by removing all waste and potential contaminants.
