3. Environmental Management Plans

3.1 Environmental Management Process

The proposed framework for environmental management during the design and construction phases of the project is detailed below. It is proposed to be undertaken in the following stages:

Draft IIS Mitigation Management Plans (MMPs)

The plans detailed in this section form the basis for management strategies during the design, construction and operational phases of the project.

Environmental Design Report

During the detailed design phase of the project, the design will be audited against the design phase requirements of the MMPs to meet the needs of the SHEQ-MS and DTAE. This audit may be undertaken by the design contractor and/or an independent auditor.

Construction Phase Environmental Management Plans (EMP)

Detailed management strategies, based on the detailed design and construction methodology, will be developed by the construction contractors, to meets the needs of the SHEQ-MS and of DTAE. The EMPs will need to address the requirements outlined in the MMPs.

Operational Phase

Monitoring programs for the operational phase of the project will be developed by Gunns to meet the requirements of the RPDC Guidelines. In addition, specific operating conditions will be developed in conjunction with DTAE as part of the project’s environmental licensing conditions. Consequently, operational phase environmental management strategies have not been included in this document.

3.2 Mitigation Management Plan Framework

The following EMPs have been developed for each major component of the project and for particular environmental and safety issues relevant to the project. The plans provide criteria and indicators to measure the environmental performance of the project during the design stage, as well as management controls to reduce potential impacts during construction and operation.

The objectives of the MMPs in relation to eliminating or reducing impacts include:

Avoidance – projects or activities that could cause adverse impacts. These are most effective at the earlier stages of a project;

Prevention – measures that impede the occurrence of negative impacts;

Preservation – prevention of future actions that may negatively impact on a resource or attribute;

Minimisation – limiting or reducing the degree of an impact;

Rehabilitation – repairing or enhancing affected resources;

Volume 4: Page 3-31 Draft Integrated Impact Satement Bell Bay Pulp Mill

Restoration – restoring an affected resource to how it was prior to the impact; and

Compensation – create or enhance a resource to compensate for what is lost.

Source: World Bank (1999).

Compliance with Australian Standards and procedures is implied for all the EMPs, even if not directly stated.

Although the EMPs are focused on environmental issues, health and safety issues are included to ensure that they are part of the design process. The EMPs also include commitments made in the Draft IIS and in the accompanying technical studies.

The EMPs include ‘performance indicators’ which can be reviewed to indicate whether the performance objective has been achieved. Monitoring will establish whether performance targets have been met. Monitoring results will be collated, interpreted and submitted to DTAE as part of an Annual Report.

Each plan incorporates the following elements:

1. Groundwater quality;

2. Surface/onshore water quality;

3. Marine/offshore water quality (where applicable);

4. Air quality (including dust and emissions);

5. Noise and vibration;

6. Erosion prevention and sediment control;

7. Terrestrial/onshore flora and fauna;

8. Marine/offshore flora and fauna (where applicable);

9. General waste management;

10. Hazardous material storage and handling;

11. Cultural heritage;

12. Social, land and marine use and economics;

13. Emergency response; and

14. Safety, health and asset.


3.3 Environmental Management Plan – Pulp Mill

The MMP applies to the pulp mill only – it does not encompass the associated wharf, water supply pipeline, effluent pipeline or landfill, or quarry and water reservoir; these are subject to separate MMPs. Construction of the pulp mill has the potential to impact on the natural, social and cultural environment in a number of ways, as described in Volume 2. The EMP (Planning) summarises the management measures proposed to control detrimental impacts and provides the outline of a monitoring strategy to assess the success of the management measures. The Alliance will develop an EMP (Construction).

The Alliance will establish and maintain a Site Yard in proximity to the pulp mill site, with equipment lay-down areas, working areas, facilities for refuelling, waste management, and storage of chemicals. It will be the responsibility of the Alliance to identify a suitable location. The Alliance will also rehabilitate the Site Yard where appropriate.

3.3.1 Groundwater Quality

The baseline environmental data for the pulp mill site (Volume 2) indicates that groundwater depth varies between 2.6m and 25m. More detailed groundwater sampling undertaken as part of the planned 2.5-year base-line monitoring program will also be considered when defining background conditions.

Construction of the pulp mill has the potential to affect groundwater if contaminants such as those listed below migrate down through the soil horizon and reach the water table:

Fuel and hydraulic fluid from plant and equipment, fuel storage and refuelling areas;

Chemicals such as paint, cement, asphalt, etc.; and

Liquid wastes including oily water from drip trays, sewerage and grey water from the Site Yard.

1. Groundwater Quality

Performance Objective

To limit the risk of contamination and potential impacts to groundwater of the surrounding environment.

Performance Indicator – During Operations

Groundwater bore monitoring indicates no significant impacts to groundwater quality based on monitoring results.

Management Actions All design and drawings comply with this MMP and EMP (Design).

All working areas will be designed so as not to impact on existing ground water quality as defined as part of the baseline monitoring program. As a minimum, design of working areas will include:

– Dedicated fuel and chemical storage areas that meet the requirements of AS1940, and are appropriately signed with content and volume. The storage areas will be sited in locations that pose low risk to any watercourses or bores. All storage areas will be bunded and all associated infrastructure (that is, hoses, pipework, etc) will be contained in accordance with the relevant Australian Standard. All bunds will contain an oily water interceptor and sump.

Volume 4: -33 Draft Integrated Impact Satement Bell Bay Pulp Mill


– Spill kits will be available at all fuel and chemical storage areas and will include response equipment specific to the intended purpose. Personnel will be trained in the use of spill kits and in general emergency response.

– Refuelling of plant, equipment and vehicles will take place in designated areas only (signed, bunded and provided with an interceptor) and in accordance with the documented refuelling procedure. All personnel will receive training on the correct refuelling procedure.

– All fixed plant will be equipped with drip trays. Drip trays will be checked after significant rainfall events, and any oily water will be collected and disposed of in such a way that prevents contamination of groundwater.

– All plant and machinery (particularly hydraulic hoses, fuel lines, etc) will be inspected daily and any defaults or signs of wear and tear reported to the Site Foreman for repair as part of a preventative maintenance program.

– Sewage and grey water produced at the Site Yard will be collected and disposed of appropriately (e.g. at a Municipal WWTP).

– All oily water collected from sumps, interceptors and drip trays will be disposed at a suitably licensed waste disposal facility.

A training register will be maintained of all personnel who have undergone the training listed above in the Management Actions section.



A number of groundwater monitoring bores are in place within the pulp mill site, and associated working areas. These will be used to detect variations in the standing water levels of the underlying aquifers and water quality analyses. The groundwater monitoring bores have been installed in proximity to planned:

– Waste storage areas (including wastewater);

– Fuel and chemical storage areas;

– Refuelling areas;

– Interceptors and sumps associated with wash down areas -; and

– Any areas highlighted as being of high groundwater vulnerability in Volume 2.

Groundwater levels and quality will be analysed prior to construction commencing in order to establish a baseline measurement. The monitoring program shall be developed in conjunction with DTAE.

During construction of the pulp mill, regular groundwater quality monitoring will be undertaken. Additional monitoring will occur if there is reason to suspect contamination has occurred, e.g. in the event of a significant spill.

Upon completion of the construction phase, groundwater levels and quality will be analysed and compared to baseline levels.

Reporting and Review

To ensure that the results of the monitoring are valid and defensible, a set of quality assurance and control procedures has been developed for this investigation. The procedures are summarised below.

Work will be carried out by a suitably qualified professional, in accordance with industry-accepted standards.

Field quality control procedures include rigorous sample collection, decontamination, handling and transfer protocols.

Pre-cleaned, disposable sampling equipment will be used, to prevent cross-contamination. Prior to installation, all non-disposable equipment used for sampling will be decontaminated using industry accepted protocols outlined below:

– Wash and/or scrub in potable water;

– Rinse or scrub in phosphate-free detergent;

– Rinse in potable water; and

– Rinse twice in distilled water.



Field quality assurance will comprise replication of field measurements in accordance with the requirement of the Monitoring Program.

The results of the laboratory quality control samples will be presented with the certified laboratory reports and included with any formal reporting as an appendix.

3.3.2 Surface/Onshore Water Quality

There are no permanent watercourses within the actual footprint of the proposed pulp mill. However, there are several watercourses in proximity to the site. These include Williams Creek (located between the existing chip mill and the proposed pulp mill site) and the Tamar River.

Construction of the pulp mill has the potential to impact on surface-water quality off-site if contaminants such as those listed below are accidentally released and are not sufficiently contained:


Chemicals such as paint;

Liquid wastes, including sewage and grey water from the Site Yard;

Sediment-laden run-off from construction work sites; and

Sediment-laden water released from excavations during dewatering and over-pumping.

2. Surface/ Onshore Water Quality


To limit the discharge of contaminated surface-water to the surrounding environment.


Surface water monitoring indicates no significant impacts to surface- water quality based on monitoring results.

Management Actions All design and drawings comply with this MMP.

All potentially contaminated water must be collected and treated on site prior to discharge.

All working areas will be designed to meet surface-water quality criteria that will be agreed with DTAE as part of the Construction EMP.

As a minimum, design of working areas will include:

– Dedicated fuel and chemical storage areas that meet the requirements of AS 1940, and are appropriately signed with content and volume. The storage areas will be sited in locations that pose low risk to any watercourses or bores. All storage



areas will be bunded and all associated infrastructure (that is, hoses, pipework, etc) will be contained within the bund. All bunds will contain an oily water interceptor and sump.



– All fixed plant will be equipped with drip trays where appropriate. Drip trays will be checked after significant rainfall events, and any contaminated water will be collected and disposed of in such a way that prevents contamination of surface water.



All oily water collected from sumps, interceptors and drip trays will be disposed at a suitably licensed waste disposal facility.

As part of the EMP (Construction), the Alliance will develop a Stormwater Management Plan prior to construction commencing.

The minimum requirements for the Stormwater Management Plan are outlined below:

– As far as reasonably practicable, uncontaminated stormwater will be diverted and/or segregated from work area runoff.

– Stormwater detention basins will be constructed to collect site runoff and minimise the direct release of stormwater from the site.

– During operation overflow stormwater will only be released to surface water during 1 in 10 year storm events.

– Excavated soil will be stockpiled in such a way as to minimise release of sediment. There will be no stockpiling in close proximity to watercourses.



– Pre-construction drainage will be required to divert excess water away from excavations and working areas to minimise sediment-laden run-off.

– Any water pumped or drained from excavations will be filtered through a suitable medium (straw bales, break tank, geotextile membrane, or settling pond) prior to being disposed of to vegetated land. There will be no direct discharge of silty water to watercourses.

Site Manager (during construction and operations). Monitoring

All monitoring will compare results against the stated standards.

During construction of the pulp mill, regular visual site inspections will be carried out to determine if there is any silty run-off from the site.

Surface water quality monitoring will be undertaken in the Tamar River and Williams Creek prior to construction commencing, in order to establish a baseline measurement, and at least monthly thereafter until completion of construction. The monitoring program shall be developed in conjunction with DTAE.

During construction of the pulp mill, water quality analyses of Williams Creek and/or the River Tamar will be carried out if there is a significant spill, or reason to suspect contamination of either watercourse has occurred as a direct result of related activities.

Should any parameters monitored fall outside of the stated water quality standards or differ by 10% or more from the baseline measurement. The EMP (Construction) and the investigation threshold will be reviewed and amended as necessary.














3.3.3 Air Quality

The dominant emission sources near the pulp mill are an aluminium smelter, ferroalloy plant, and a gas fired power station. Emissions from the Bell Bay Industrial Estate include sulphur dioxide, nitrogen dioxide, particulate matter and hydrogen fluoride (Volume 2). Gunns installed an air quality monitoring station adjacent to the mill site in July 2005, to measure PM10, SO2, TRS and NO2 and several meteorological parameters. The recently collected data (July 2005 – to date) indicates low values for all pollutant parameters measured, which are within the relevant NEPM Ambient Air Standards. Point source monitoring of emissions will be initiated upon commissioning of the pulp mill project and will be further detailed in the EMP (Operation).

Air quality impacts resulting from construction of the pulp mill have the potential to occur by:

Release of particulates from dust; and

Release of greenhouse gases from construction plant and machinery.


3. Air Quality


To limit the release of air pollutants into the surrounding air shed.


Air emissions from the works do not cause significant impacts outside of the site boundaries from dust, odour, smoke and fumes.

Management Actions All design and drawings will comply with this MMP and EMP (Design).

The design will include the ability to generate biofuel power as part of the pulp mill plant.

Air emissions will be controlled in accordance with the relevan5t standards.

Water spraying will be utilised as required (that is, when in close proximity to sensitive receptors such as houses) to dampen dust on working areas and/or access tracks.

Speed limits will be reviewed during extended periods of dry weather to minimise dust generation.

All plant and equipment will be regularly serviced and well maintained in order to reduce emissions of greenhouse gases.

Use of ozone depleting substances will not be permitted.

Burning of waste materials on site will not be permitted, except in the instance of controlled burning of cleared vegetation.

If necessary, earthworks will cease during strong wind conditions.

When travelling on gazetted public roads, loads on haul trucks will be covered to minimise dust emissions.

Monitoring Monitoring will be based on the air quality standards given in Section 4.

Meteorological monitoring will continue to provide baseline data prior to and during the pulp mill construction period.


3. Air Quality

Continuous ambient air quality monitoring will continue to be undertaken prior to and during the pulp mill construction period.

Visual inspections of working areas and access tracks will be carried out regularly to monitor dust levels. Community liaison (including any records of complaints) will reveal any areas of specific concern.


A community complaints register will be maintained in order to identify areas where dust management is a significant problem.

3.3.4 Noise

The proposed pulp mill site is located within a generally hilly landscape, with the nearest residents located across the Tamar River, approximately 1.5km away.

Major sources of noise during construction of the mill will include the equipment associated with blasting, excavating, crushing, screening and transporting of heavy material.

4. Noise


To limit the noise emissions from facilities, equipment and machinery to mitigate potential impacts to the workforce, surrounding residents and faunal populations.


Noise levels do not exceed licence conditions or stated industry practice guidelines.


All activities will comply with the noise standards as described in Section 4.

Undertake noise surveys at various locations prior to construction commencing, in order to establish baseline measurements. Continuous noise surveys will be carried out over, daytime (7 am to 7 pm), evening (7 pm to 10 pm) and night time (10 pm to 7 am) and, as a minimum, at the following locations:

– The boundary of the pulp mill site; and

– At the nearest practicable Rowella residence.

Low noise equipment will be used. Regular servicing and maintenance of plant will be undertaken to ensure optimum performance.


4. Noise

Where appropriate, noise barriers will be erected between sensitive receptors and construction operations, e.g. cladding, soil mounds or straw bale barriers around pumps and generators.

Where practicable, excessive noise generating activities will be undertaken during daytime operating hours.

All plant and machinery will be turned off when not in use. Equipment found to be producing noise in excess of the EMPCA Noise Regulations will be taken out of use, and repaired or removed from site.

Inform local residents in advance of any particularly noisy operations, e.g. blasting.

Blasting at the mill site will be limited to twice a day, between the hours of 9.00am and 3.00pm.

Crushing plant will be located as far away from sensitive receptors as practicable.

Supply employees with hearing protection as required and provide training on the importance of use. Clearly signpost areas where the use of hearing protection is required.

Monitoring Noise monitoring will be carried out continuously.

During construction, spot surveys may be carried out at sensitive locations. .

Additional monitoring will be required during particularly noisy activities (e.g blasting, sheet piling). Noise monitoring will be carried out at different times of day, e.g daytime, evening and night-time.


4. Noise

Monitoring will be undertaken in accordance with protocols contained in Noise Measurements Procedures Manual, (DPIWE 2004).

Noise monitoring may need to be further modified to meet possible licence requirements, and if complaints are received from nearby residences.

Vibration and air blast will be monitored on an ongoing basis and blast parameters will be modified accordingly. In particular, residents at Rowella will be monitored for vibration.

Reporting and Review As required, noise contours will be prepared using baseline noise

readings, for different times of the day (daytime, evening and night time).

A database of recorded noise readings will be maintained, and the results compared to the baseline noise levels and noise limits in Section 4. Non-compliances will be reported, as well as the remedial action taken to address the issue.

Reporting and review procedures will be developed further prior to construction, and will be dependent on any licence requirements.

3.3.5 Erosion Prevention and Sediment Control

The majority of the land near the pulp mill is characterised as having a high risk of erosion (Volume 2).

Construction of the pulp mill will require cut and fill of large volumes of soil and has the potential to result in erosion and subsequent sediment release to the surrounding environment for the following reasons:

Vegetation will be cleared, leaving the topsoil exposed;

Topsoil and subsoil will be stockpiled in mounds; and

Inadequate compaction during backfilling combined with weakened soil structure may make the site more susceptible to water erosion.

These issues may be exacerbated by the steep slopes found across the pulp mill site.


5. Erosion Prevention and Sediment Control


To limit the erosion and sediment load to that similar to natural soil movement.


Sediment load monitoring and environmental audits indicate no significant impacts from erosion.


Undertake soil and geotechnical assessment (including testing for Acid Sulphate Soils) during the detailed design phase.

Limit the total area of disturbance, or ‘project footprint’ to the minimum required for the project.

An Erosion and Sediment Control Plan will be developed prior to construction commencing. This will address the following:

– Safeguard of topsoil by stripping and stockpiling prior to construction.

– In areas where no permanent structures are to be installed, 10-15 cm of topsoil will be replaced to promote vegetation growth. Supplementary seeding with native grasses/pastures (as appropriate) may be utilised in areas of particularly high risk of erosion e.g. steep slopes.

– As far as practicable, land will be progressively disturbed during construction to ensure minimum exposure to the influence of weather conditions (e.g. rainfall and wind).

– Design erosion control structures such as diversion banks and berms to limit topsoil movement as necessary.

– Design topsoil stockpiles to prevent excessive loss by wind and water erosion.

– Ensure that erosion and sediment control measures are constructed in high risk areas.

– Install pre-construction drainage where necessary. Design drainage outfalls to divert flow and control runoff, and ensure adequate scour protection. This may include utilising riprap (rocks held with wire mesh), revegetation and/or geotextile material.


Standard N/A





Monitoring Compaction tests will be carried out at regular intervals during backfilling, to ensure soil compaction ranges 90% to 110% of the compaction of adjacent undisturbed soils. A record of all compaction tests will be maintained.

A photographic record of the site will be prepared upon completion of construction works. This will be utilised as a baseline against which to monitor any future erosion.

Monthly site inspections will be carried out on completion of construction, for a period of time that will encompass autumn and winter. The physical extent of erosion (rills and gullies) will be noted and, if the erosion does not stabilise, remedial earthworks will be undertaken.

The monitoring program will be developed further prior to construction commencing and will be incorporated into the Construction EMP.


Reporting and review procedures will be developed prior to construction commencing.

3.3.6 Terrestrial Flora and Fauna

Field surveys indicate the flora at the pulp mill site is of State conservation importance due to the presence of ten confirmed species of State significance, 1 unconfirmed species of State significance and five ecological vegetation communities of State significance (based on the TASVEG classification system).

Construction of the pulp mill will affect terrestrial flora and fauna in the following ways:

Loss of or damage to native vegetation (including ecologically threatened communities) across the pulp mill site, at the Site Yard, and associated access tracks;

Loss of habitat for terrestrial fauna (both temporary and permanent);

Habitat fragmentation, resulting in populations becoming separated from one another;

Loss of or damage to species of state significance;

Noise, vibration, light and dust impacts on local flora and fauna;

Potential introduction and/or spread of weeds, pest species and diseases such as Phytophthora cinnamomi to the site; and

Altered fire and/or grazing regimes that may change species composition.


6. Terrestrial Flora and Fauna


To limit the negative impacts on the significant flora and fauna species and habitat of communities potentially affected by the project.


Disturbance to flora and fauna habitat is restricted to footprint areas and adjacent areas are not significantly impacted.


The Site Project Manager will prepare a Vegetation and Fauna Management Plan which addresses the following:

– Limit the clearing of vegetation to that essential for the project (during design this applies to the ‘footprint’ of disturbance).

– Where practicable, locating Site Yard and other project facilities to avoid sensitive habitats or areas known to support protected species.

– Install fencing in areas that are within the development footprint but are planned for non-disturbance.

– Design night-lights such that they are not directed onto sensitive habitat areas. Limit light spillage as far as possible.

– Rehabilitation of disturbed areas of the site, which are not required for ongoing mill operations, to minimise the total amount of permanent habitat loss.

– Fauna inhabiting the area are to be allowed to relocate naturally. Construction crews will be educated regarding management of fauna (that is, not to kill fauna including snakes).

– Prior to entry to the construction site, machinery will be washed down to ensure removal of foreign soil, vegetation and debris.

– Ongoing ecological assessment will be undertaken internally by appropriate staff to ensure a detailed understanding of local landscape processes, which may affect ultimate restoration success.

– Topsoil stripped from the site will be stockpiled separately from subsoil and used for rehabilitation, where practicable. Topsoil stockpiles will be protected from erosion and water-logging to ensure the natural seed bank stored in the soil remains viable.

– Where applicable, on completion of the works, disturbance of rehabilitated areas will be minimised by fencing to facilitate revegetation.



A weed management strategy will be developed, to assist in preventing the introduction of weeds and diseases to the site and will include a program of weed eradication in affected areas. This will be incorporated into the Vegetation and Fauna Management Plan.

Rehabilitation may require the establishment of a native seed bank prior to construction commencing.

Establish the extent (if any) of Phytophthora cinnamomi, install wheel wash facilities to prevent its introduction and use reliable, clean sources for gravel and other fill materials. Restrict access to known infected areas and restrict construction to summer months wherever possible, as the pathogen is less likely to spread in dry conditions.

A fire management strategy will be developed that takes into account the regenerative requirements of the species present while still aiming to protect assets and limit the encroachment of shrubs into areas of remnant grassland. The location of firebreaks will be minimised and carefully selected. Firebreaks will consist of slashed vegetation, not bare earthen boundaries. This will be incorporated into the Vegetation and Fauna Management Plan.

Where appropriate, maintain native herbivore grazing regimes in order to maintain open grass swards and high species diversity.

Consider the development of habitat offsets elsewhere, to compensate for the loss of vegetation on site.


Standard Environment Protection and Biodiversity Conservation Act, 1999 (Commonwealth).

Threatened Species Protection Act, 1999.

Forest Practices Act 1985



Monitoring For areas of the site that are to be rehabilitated, a photographic record of will be prepared prior to construction commencing. This will be used as a baseline (along with pre-construction baseline assessment data obtained as part of the Draft IIS) against which to measure the success of rehabilitation.



On completion of the construction works, monthly visual inspections of the rehabilitated areas will be carried out, for a period of time that will encompass autumn and winter (that is, the period of highest rainfall).

The success of natural revegetation of the alignment will be assessed by comparison of the percentage and species composition of vegetation cover to the pre-construction baseline. Remedial action may include further earth works or supplementary seeding with native seeds appropriate for the habitat in question.

Monitoring procedures will be developed further prior to construction and may require specific strategies for individual protected species.


Reporting and review procedures will be developed prior to construction.

3.3.7 General Waste Management

The general hierarchy of waste management principal will be applied to all general waste generated by the pulp mill project. The majority of non recyclable waste produced during construction of the pulp mill will be stored on site, in readiness for later disposal at the new landfill site. This landfill will accept inert and non-hazardous waste only. Hazardous waste and putrescible waste will be disposed of to a suitably licensed Municipal facility.

Inadequate waste management may result in the following impacts:

Potential contamination of soils, surface-water and groundwater;

Potential ingestion and/or entanglement in litter and waste by native fauna and livestock;

Spread of disease through the introduction of vermin;

Spread of weed through introduction of green waste;

Potential fire hazard;

Impacts upon visual amenity; and

Generation of odours.


7. General Waste Management


To manage waste generated on site in a sustainable way and ensure impacts on the surrounding environment are minimised.


Key Performance Indicators (KPI) for waste recycled, waste generation, waste re-use and management of site landfills are achieved.

Monitoring indicates no significant impacts to the surrounding environment.


A licensed contractor will be used for all waste to be removed from site. Waste Tracking Certificates will be completed for all regulated waste and kept in the site offices as part of the project Environmental Record. Non-regulated waste will not be tracked. However, a log of all waste types produced will be maintained, along with approximate quantities generated.

The waste management system will follow the waste hierarchy (Reduce; Reuse; Recycle; Responsible Disposal).

Procurement of materials brought on site must consider the amount of waste generated, and consideration be given to reducing this at the procurement stage. Consideration must also be given to the cost of waste disposal, any necessary pre-disposal treatment required and the risk of contamination.

All waste will be stored in appropriate containers and protected from adverse weather and vermin. All waste disposal containers will be clearly labelled.

There will be designated waste storage areas at the Site Yard, with containers stored in bunded (and preferably covered) areas.

Waste storage areas will not be located immediately adjacent to any surface-water or bores.

All personnel will be provided with training on waste management.


Standard Waste Recovery and Recycling Directory.

Environmental Management and Pollution Control (Waste Management) Regulations, 2000





Monitoring Weekly inspections of waste storage areas will be carried out, to ensure compliance with the waste management system.


A waste log will be established and kept up to date for each waste stream produced. The log will record approximate quantities of waste re-used, recycled, treated and disposed of. These will be compared to the waste management KPIs to be set during the detailed design stage.

Monitoring procedures will be further developed prior to construction.

Reporting and Review Summary reports of the waste management inspections will be

produced, documenting any non-compliance with the waste management system and remedial action taken.

Reporting measures to relate the waste log to the target KPIs will be developed prior to construction.

3.3.8 Hazardous Materials Storage and Handling

Construction of the pulp mill will require the storage and use of various hazardous materials. Examples include fuel, hydraulic oil and paint.

Impacts from spills and accidental releases of hazardous and/or toxic materials may pose a risk to both human health, and the surrounding environment (flora and fauna, soil, water), depending on the specific substance in question.


8. Hazardous Material Storage and Handling


To limit the risk of contamination and potential impacts from the use of hazardous and/or toxic substances, to human health and the receiving environment.


Environmental incident statistics indicate no significant spills have occurred to land or water.


Hazard Identification (HAZID) workshops will be conducted to determine high and extreme risk events for potential contamination in relation to an accident event. Where possible, design to eliminate the risk or reduce it to as low as reasonably practical.

Fuel and chemical storage areas will be bunded according to AS1940, to contain any potential spills. They will not be located immediately adjacent to any surface-water or bores.

Bunded storage areas must be of sufficient capacity to contain 110% of the potential volume that could be spilt from the largest vessel within the bund. All hoses, valves, and pipework are to be contained within the bund. Bunds will drain to an interceptor and sump.

Storage areas will be clearly labelled with the quantity and characteristics of the chemical stored. Manufacturers’ Material Safety Data Sheets (MSDS) will be available which indicate the appropriate action to be taken in the event of a spill.

Spill kits appropriate for the hazardous material spill response will be available at all fuel and chemical storage areas. Personnel will be trained in spill response.

Procedures will be documented for the correct handling and use of all hazardous materials and personnel will be trained accordingly.

Refuelling of plant, equipment and vehicles will be carried out in designated areas in accordance with documented procedures.

All spills or incidents must be reported to the Site Foreman and, if required, to the appropriate Regulatory Authority.




Standard Dangerous Goods Act, 1998.

Dangerous Goods Regulations, 1999.



Monitoring A record will be maintained of all personnel who have undergone the training listed above in the Management Actions section.

Regular stock-takes will be carried out at fuel and chemical storage areas to ensure the minimum required amounts of hazardous materials are stored on site.

Daily site inspections will record any spills or non-compliances and the remedial action taken.

Monitoring procedures will be developed further, prior to construction, as the material storage and handling quantities will be determined during detailed engineering design.

Reporting and Review A register will be kept of all spills and incidents. This will be used to

identify trends and issues for which the EMP (Construction) may require amendment.

Significant spills may require reporting to the appropriate Regulatory Authority.

3.3.9 Cultural Heritage

The pulp mill is located within the Tippogoree Hills, one of 29 sites ranked as “Recommended Area for Protection” as a result of a 1997 survey commissioned by Forestry Tasmania. Desk-based assessment and follow-up fieldwork has identified sites of Local (and potentially Regional) Historic heritage significance and sites of Aboriginal heritage significance requiring further consideration.

Aboriginal Heritage

Site specific management strategies for the Aboriginal sites identified above are detailed in this section. All site specific management prescriptions, protocols and protection measures will be incorporated into the Cultural Heritage Management Plan. Specific locations of sites will be maintained as confidential information.

The following strategies have been developed based on the recommendations of the consultants, and have been further developed in consultation with the Aboriginal Heritage Office (DTAE).


TASI 9896

This site is approximately 7.8 ha in size, consisting and bounded by three artefacts scattered over several hundred metres. The site is located on the main rise to be developed for the pulp mill. It is suggested that this site may extend into the subsurface in this locality beyond the current known location (Stone and Stanton 2006).

The artefact located within the temporary car park will remain in situ and be protected during construction activities. A reserve of minimum 1m x 1m will be applied with the boundary to be indicated clearly by temporary fencing for the duration of construction activities.

The two remaining artefacts will require a permit to relocate. These artefacts will be moved to the 2 ha reserve area indicated for TASI 9903.

Subsurface testing of the organic soil horizon will be undertaken over the remainder of the site to determine the full context of the site. This activity will be controlled by an Aboriginal Heritage Officer. If subsurface Aboriginal heritage values are identified the following will be applied:

– A permit will be required to undertake a full archaeological examination to recover as much information as possible from the site. All information to be provided to the Tasmanian Aboriginal Land and Sea Council.

3.4 Mitigation Management Plan – Wharf Facility

This MMP applies to the wharf facility only. Construction of the wharf has the potential to impact on the natural, social and cultural environment in a number of ways, as described in Volume 2. The MMP summarises the management measures proposed to control detrimental impacts and provides the outline of a monitoring strategy to assess the success of the management measures. The Alliance will develop an EMP (Construction).

The Alliance will establish and maintain a Site Yard in proximity to the wharf, with equipment lay-down areas, working areas, facilities for refuelling, waste management, and storage of chemicals. The Alliance will also rehabilitate the Site Yard where appropriate.


Construction of the wharf has the potential to affect groundwater if contaminants such as those listed below migrate down through the soil horizon and reach the water table:


Chemicals such as paint; and

Liquid wastes including oily water from drip trays, sewerage and grey water from the Site Yard.







All working areas will be designed to meet the groundwater quality standards in Section 4. As a minimum, design of working areas will include:

– Dedicated fuel and chemical storage areas that meet the requirements of AS 1940, and are appropriately signed with content and volume. The storage areas will be sited in locations that pose low risk to any watercourses or bores. All storage areas will be bunded and all associated infrastructure (that is, hoses, pipework, etc) will be contained in accordance with the relevant Australian Standard. All bunds will contain an oily water interceptor and sump.





– All fixed plant will be equipped with drip trays. Drip trays will be checked after significant rainfall events, and any oily water will be collected and disposed of in such a way that prevents contamination of groundwater.



– All oily water collected from sumps, interceptors and drip trays will be disposed at a suitably licensed waste disposal facility


Ongoing comparison with Groundwater Quality Standards (Section 4).

Standard EMP (Design), Section 4, Groundwater Quality Standards.


State Policy of Water Quality Management, 1997. Responsibility



Monitoring All monitoring will compare results against the criteria identified in the

Monitoring Plan (Section 4).


A number of groundwater monitoring bores are in place around the wharf site. These will be used to detect variations in the standing water levels of the underlying aquifers and water quality. The groundwater monitoring bores have been installed in proximity to planned:

– Waste storage areas (including wastewater);

– Fuel and chemical storage areas;



– Refuelling areas;

– Interceptors and sumps associated with any wash down areas ; and

– Any areas highlighted as being of high groundwater vulnerability in Volume 2.

Groundwater levels and quality will be analysed prior to construction commencing in order to establish a baseline measurement. The monitoring program shall be developed in conjunction with DTAE.

During construction of the wharf facility, further groundwater quality monitoring will be undertaken. Additional monitoring will occur if there is reason to suspect contamination has occurred, e.g. in the event of a significant spill.















The wharf will be located on the eastern shore of the Tamar River adjacent to Bell Bay. Construction of the wharf has the potential to impact on the surface-water quality of the river in the event that contaminants such as those listed below are accidentally released and/or not sufficiently contained:


Chemicals such as paint, concrete, road sealant, anti-fouling chemical (from ship hulls, during berthing, mooring, unloading).;

Liquid wastes including sewage and grey water from the Site Yard;

Sediment-laden run-off from construction work sites;

Sediment-laden water released from excavations during dewatering and over-pumping; and

Generation of turbidity plumes from re-suspended sediment associated with pile driving, rock armouring, trestle installation and vessel movement.





Water monitoring indicates no significant impacts to surface-water quality based on monitoring results.


All potentially contaminated water must be collected and treated on site prior to discharge.



– Dedicated fuel and chemical storage areas that meet the requirements of AS 1940, and are appropriately signed with content and volume. The storage areas will be sited in locations that pose low risk to any watercourses or bores. All storage areas will be bunded and all associated infrastructure (that is, hoses, pipework, etc) will be contained within the bund. All bunds will contain an oily water interceptor and sump.

– Spill kits will be available at all fuel and chemical storage areas and will be include response equipment specific to the intended purpose. Personnel will be trained in the use of spill kits and in general emergency response.








As part of the EMP (Construction) the Alliance will develop a Stormwater Management Plan prior to construction commencing.






– Any water pumped or drained from excavations will be filtered through a suitable medium (straw bales, break tank, geotextile membrane, or settling pond) prior to being disposed of to vegetated land. There will be no direct discharge of silty water to watercourses.



All ships will be required to comply with the Australian Ballast Water Management Requirements.

Marpol convention Responsibility


Site Project Manager (during construction and operations). Monitoring

All monitoring will compare results against the stated standards (Section 4).

Surface water quality monitoring will be undertaken at the Tamar River prior to construction commencing in order to establish a baseline measurement, and at least monthly thereafter until completion of construction. The monitoring program shall be developed in conjunction with DPIW.

During construction of the wharf facilities, additional water quality monitoring of the Tamar River will be undertaken in the event of significant rainfall, or if there is reason to suspect contamination has occurred, from a significant spill or as a direct result of related activities.

Should any parameters monitored fall outside of the stated water quality standards (Section 4) or differ by 10% or more from the baseline measurement. The EMP (Construction) and the investigation threshold will be reviewed and amended as necessary.














3.4.3 Air Quality

The wharf will be located within the Port of Launceston’s existing industrial estate, which is zoned as “Major Industrial”. Emissions from the Bell Bay Industrial Estate include sulphur dioxide, nitrogen dioxide, particulate matter and hydrogen fluoride.

Air quality impacts resulting from construction of the wharf have the potential to occur by:



3. Air Quality






The design will include the ability to generate biofuel power as part of the pulp mill plant.

Air emissions will be controlled in accordance with the standards provided in Section 4.


3. Air Quality


All plant and equipment will be regularly serviced and well maintained in order to reduce vehicular emissions.



Loads on haul trucks will be covered to minimise dust emissions.


Standard Section 4, Air and Noise Quality Standards.





Visual inspections of working areas and access tracks will be carried out regularly to monitor dust levels.

Community liaison (including any records of complaints) will reveal any areas of specific concern.


A community complaints register will be maintained in order to identify any areas where dust management is a significant problem.

3.4.4 Noise and Vibration

Noise and vibration are both processes which will be out puts of both the mill and associated infrastructure construction and the ongoing operation of such.

Excessive noise from construction of the wharf has the potential to cause detrimental impacts on the project workforce, nearby residents, livestock and local fauna. The nearest residences are located at the community of Rowella, approximately 1.5km away and across the Tamar River.

Construction activity can result in varying degrees of ground vibration depending on the equipment and methods employed. Operation of construction equipment causes ground vibration which diminish in


strength with distance. Buildings founded on the soil in the vicinity of the construction site respond to these vibrations with varying results, ranging from no perceptible effects at the lowest levels, low rumbling and perceptible vibrations at moderate levels and slight building damage at the highest levels.

Ground vibrations from construction activities very rarely reach the levels that can damage structures, but they can achieve the audible and perceptible ranges in buildings very close to the site. As pile driving is only proposed for the wharf facility, and there are no structures within 1 km of the work area, pile driving is not likely to result in any vibration risks to structures.

4. Noise and Vibration








Noise barriers will be erected between sensitive receptors and construction operations, e.g. cladding, soil mounds or straw bale barriers around pumps and generators and underwater air curtains.




Supply employees with hearing protection as required and provide training on the importance of use. Clearly signpost areas where the use of hearing protection is required.

Although pile driving is required at the wharf, there are no buildings within 1km therefore there are no anticipated impacts due to vibration. Where practicable, sonic or vibration piles will be used instead of impact piling.


4. Noise and Vibration

Establish a direct line of communication with the nearby Van Diemen Aquaculture Facility.




NSW DEC Environmental Noise Control Manual and Industrial Noise Policy.



Monitoring Noise monitoring will be carried out continuously.

During construction spot surveys may be carried out at sensitive locations.

Monitoring will be undertaken using protocols contained in the Noise Measurements Procedures Manual (DPIWE,2004). The analysis of the noise monitoring results will take into account existing background noise levels.

Noise monitoring may need to be further modified to meet possible licence requirements, and if complaints are received from nearby residences.

Reporting and Review As required, noise contours will be prepared using baseline noise

readings, for different times of the day (daytime, evening and nighttime).

A database of recorded noise readings will be maintained, and the results compared to the baseline noise levels and noise limits in Section 4Non-compliances will be reported, as well as the remedial action taken to address the issue.



The majority of the land upon which the wharf construction works will be undertaken is characterised as having a high risk of erosion.


Construction of the wharf has the potential to result in erosion and subsequent sediment release to the surrounding environment for the following reasons:


Topsoil and subsoil will be stockpiled in mounds, making it susceptible to wind and water erosion; and

Inadequate compaction during backfilling and weakened soil structure may make the site more susceptible to water erosion,.



To limit the erosion and sediment load increase above natural soil movement.







– In areas where no permanent structures are to be installed, 10-15 cm of topsoil will be replaced to promote vegetation growth. Supplementary seeding with native grasses/pastures (as appropriate) may be utilised in areas of particularly high risk of erosion (e.g. steep slopes).




– Ensure that erosion and sediment control measures are constructed in high-risk areas.

– Reclamation area will be kept above the average low tide mark

– A rock bund will first be constructed around the perimeter of the reclamation area to contain disturbed sediments.

– Install pre-construction drainage where necessary. Design drainage outfalls to divert flow and control runoff, and ensure adequate scour protection. This may include utilising riprap



(rocks held with wire mesh), revegetation and/or geotextile material.

– Design for a complete suspended structure on piles so that the hydrodynamic conditions arising from construction are unlikely to cause erosion either up- or down-stream.

– Stabilise the banks of the Tamar River within the development footprint.


Standard N/A





Monthly site inspections will be carried out on completion of construction, for a period of time that will encompass autumn and winter (that is, periods of high rainfall). The physical extent of erosion (rills and gullies) will be noted and, if the erosion does not stabilise, remedial earthworks will be undertaken.





A range of potential direct and indirect impacts are relevant to the construction and ongoing operation of the pulp mill. These impacts may be direct or indirect, adverse or beneficial, short or long term, temporary or irreversible.

Construction of the wharf may affect terrestrial flora and fauna in the following ways:


Loss of or damage to native vegetation (including ecologically threatened communities) across the wharf site, at the Site Yard and associated access tracks.;

Resulting loss of habitat for terrestrial fauna (both temporary and permanent);





Altered fire and/or grazing regimes that can change species composition.






Management Actions

All design and drawings comply with this MMP and EMP (Design).



– Where practicable, locating Site Yard and other project facilities to avoid sensitive habitats or areas known to support protected species.

– Install fencing in areas that are within the development footprint but are planned for non-disturbance.

– Design night-lights such that they are not directed onto sensitive habitat areas. Limit light spillage as far as possible.

– Rehabilitation of disturbed areas of the site, which are not required for ongoing mill operations, to minimise the total amount of permanent habitat loss.






– Topsoil stripped from the site will be stockpiled separately from subsoil and used for rehabilitation, where practicable. Topsoil stockpiles will be protected from erosion and waterlogging to ensure the natural seed bank stored in the soil remains viable.

– Where practicable, on completion of the works, disturbance of rehabilitated areas will be minimised by fencing to facilitate revegetation.

A weed management strategy will be developed, to assist in preventing the introduction of weeds and diseases to the site and will include a program of weed eradication in affected areas. This will be included in the Vegetation and Fauna Management Plan.

Establish the extent (if any) of Phytophthora cinnamomi, install wash facilities to prevent its introduction and use reliable, clean sources for gravel and other fill materials. Restrict access to known infected areas and restrict construction to summer months wherever possible, as the pathogen is less likely to spread in dry conditions.

Develop a fire management strategy that takes into account the regenerative requirements of the species present while still aiming to protect assets and limit the encroachment of shrubs into areas of remnant grassland. The location of firebreaks will be minimised and carefully selected. Where practicable, firebreaks will consist of slashed vegetation, not bare earthen boundaries. This will be included in the Vegetation and Fauna Management Plan.

Where appropriate maintain native herbivore grazing regimes in order to maintain open grass swards and high species diversity.

Reporting and Review Reporting and review procedures will be developed prior to construction.


3.4.7 Marine/Offshore Flora and Fauna

An ecological survey at the wharf site was carried out by Aquenal in 2005. The following habitats observed:

Soft sediments and fine sands between the sub-tidal zone and 10m; and

Dense oyster beds with encrusting biota at depths > 10m.

The inter-tidal community at the wharf site has relatively high species diversity, but shows some signs of modification. There are a number of introduced species in addition to some locally rare species.

7. Marine/Offshore Flora and Fauna


To constrain the negative impacts on the marine flora and fauna habitat of communities potentially affected by the project.




Where practicable, piling and shoring activities are to be undertaken outside times of ecological sensitivity (that is, giving consideration to breeding cycles of key species.).

Construction crews will be educated regarding management of fauna. (that is, not to kill fauna). Fishing will not be permitted off the wharf facility.

Night lighting may disorientate sea birds. Lights will be designed to attempt to minimise impacts.

No blasting will be undertaken as part of the pile driving activity. Air curtains will be used if considered appropriate.

All ships will comply with current Australian Quarantine Inspection Service (AQIS) procedures and the Australian Ballast Water Management Requirements.


Standard Threatened Species Protection Act, 1999

EPBC Act 1999



Monitoring A benthic fauna/flora monitoring program will be developed and implemented immediately before and after wharf construction.



A marine pest-monitoring program will be developed and implemented to establish a baseline of pests already present in the wharf vicinity. The program will then be replicated annually to monitor pest presence or absence.

Other monitoring procedures will be developed prior to construction.




The general hierarchy of waste management principal will be applied to all general waste generated by the pulp mill project. The majority of non recyclable waste produced during construction of the wharf will be stored on site, in readiness for later disposal at the new landfill site. This landfill will accept inert and non-hazardous waste only. Hazardous waste and putrescible waste will be disposed of to a suitably licensed Municipal facility.





Spread of weeds through the introduction of green waste;








Key Performance Indicators (KPI) or waste recycled, waste generation, waste re-use and management of site landfills are achieved.



A licensed contractor will be used for all waste to be removed from site. Waste Tracking Certificates will be completed for all regulated waste and kept in the site offices as part of the project Environmental Record. Non-regulated waste will not be tracked. However a log of all



waste types produced will be maintained, along with approximate quantities generated.

Construction of wharf will require the storage and use of various hazardous materials. Examples include fuel, hydraulic oil and paint.




To limit the risk of contamination and potential impacts from the use of hazardous and/or toxic substances to human health and the receiving environment.







Storage areas will be clearly labelled with the quantity and



characteristics of the chemical stored. Manufacturers’ Material Safety Data Sheets (MSDS) will be available which indicate the appropriate action to be taken in the event of a spill.













Monitoring procedures will be developed further prior to construction, as the material storage and handling quantities will be determined during detailed engineering design.






All sites of Historic Heritage Significance will be protected within the reserve network for the site.

Two sites of Historic Heritage Significance have been identified in close proximity to the area to be developed for the Wharf: the Big Bay Stone Piles (site 4B) and Big Bay House Site (site 3B).

The Big Bay Stone Piles were identified as Medium significance with the recommendation to protect from all impacts. The entirety of the site will be protected within the reserve network for the site, however, the southern most stone pile is located within close proximity to the development area. A reserve buffer of 10m will be implemented to ensure no impact on the site from the development.

The Big Bay House Site was identified as High significance with the recommendation to protect from all impacts. The entirety of the site will be protected within the reserve network for the site, however, this site is located within close proximity to the development area. A reserve buffer of 10m to be implemented to ensure no impact on the site from the development.





No complaints are received concerning cultural heritage from the local or regional communities.



A Cultural Heritage Management Plan will be prepared prior to the construction phase for the management of both Aboriginal and Historic Heritage sites. The Plan will incorporate the site specific recommendations detailed above.










Where practicable, culturally significant sites will be avoided when locating access roads, Site Yard and associated infrastructure.

Conduct community consultation process with TALSC and any other potentially affected people prior to construction commencing.

Significant sites will be designated as prohibited areas to ensure they are not destroyed or affected.

3.5 Mitigation Management Plan – Landfill, Quarry and Local Water Supply Reservoir

In addition to the proposed quarry and local water supply reservoir (not to be confused with Lake Trevallyn), this MMP applies to construction of the new non-hazardous waste landfill facility only. This plan does not apply to operation of the landfill (that is, including leachate monitoring), which will be covered in an EMP (Operation).

Construction of the landfill, quarry and water supply reservoir has the potential to impact on the natural, social and cultural environment in a number of ways. The MMP summarises the mitigation measures proposed to control detrimental impacts and provides the outline of a monitoring strategy to assess the success of the mitigation measures. The Alliance will develop an EMP (Construction)

At all times, works at the proposed landfill will comply with the Sustainability Guide for the Siting, Design, Operation and Rehabilitation of Landfills, (DPIWE 2004).

The Alliance will establish and maintain a Site Yard in proximity to the landfill site, with equipment lay-down areas, working areas, facilities for refuelling, waste management, and storage of chemicals. The Alliance will also rehabilitate the Site Yard where appropriate.


The groundwater near the landfill site is not suitable for use as potable water.

Two groundwater-monitoring bores have been installed at the proposed new landfill site, indicating that groundwater levels below ground surface range between 3m towards the lower (southern) end and 10m+ towards the upper (northern) end. However, it must be noted that these samples were retrieved during a period of dry weather and actual groundwater levels may vary throughout the year in response to rainfall.

A borehole at the southern end of the site intersected a highly fractured zone from 24 to 28 m, which is considered to be a potential groundwater passage.

Construction of the landfill may affect groundwater if contaminants such as those listed below migrate down through the soil horizon and reach the water table:

Fuel and hydraulic fluid from plant and equipment, fuel storage and refuelling areas; and

Liquid wastes including oily water from drip trays, sewage and grey water from the Site Yard.









All working areas will be designed to meet the groundwater quality standards in Section 4. As a minimum, the design of working areas will include:




– All fixed plant will be equipped with drip trays. Drip trays will be checked after significant rainfall events, and any oily water will be collected and disposed of at a facility appropriately approved for that purpose.

– All plant and machinery (particularly hydraulic hoses, fuel lines, etc) will be inspected daily and any faults or signs of wear and tear reported to the Site Foreman for repair as part of a preventative maintenance program.

– Sewage and grey water produced at the Site Yard will be collected and disposed of at a facility appropriately approved for that purpose (e.g. at a Municipal WWTP).


The landfill will be constructed with a geosynthetic clay liner and High Density Polyethylene (HDPE) membrane to prevent leachate entering the groundwater system. The landfill design will incorporate cut off drains to intercept surface runoff that would otherwise flow onto the landfill area.







State Policy on Water Quality Management, 1997. Responsibility




A training register will be maintained of all personnel who have undergone the training listed above in the Mitigation Actions section.

A number of groundwater monitoring bores have been installed within the vicinity of the landfill site. These will be used to detect variations in the standing water levels of the overlying aquifers and the water quality analyses. It may be necessary to install additional groundwater monitoring bores at the Site Yard (fuel storage and refuelling areas) and/or at any areas highlighted as being of high groundwater vulnerability in Volume 2.

– Groundwater levels and quality will be analysed prior to construction commencing in order to establish a baseline measurement. The monitoring program will be developed in conjunction with DTAE.

During construction of the landfill, regular groundwater quality monitoring will be undertaken. Additional monitoring will occurif there is reason to suspect contamination has occurred, e.g. in the event of a significant spill.


Reporting and Review To ensure that the results of the monitoring are valid and

defensible, a set of quality assurance and control procedures has been developed for this investigation. The procedures are summarised below.



Pre-cleaned, disposable sampling equipment will be used, to prevent cross-contamination. Prior to installation, all non- disposable



equipment used for sampling will be decontaminated using industry accepted protocols outlined below:








The new landfill site is located within the sub-catchment of Williams Creek, which drains into the Tamar River, north of the existing woodchip mills. There are no known potable surface-water sources in proximity to the landfill site.

Construction of the landfill may affect surface-water quality off-site if contaminants such as those listed below are accidentally released and are not sufficiently contained:


Chemicals such as cement and road sealant;

Liquid wastes including sewage and grey water from the Site Yard;


Sediment-laden water released from excavations during dewatering and over-pumping.



To limit the discharge of contaminated surface water to the surrounding environment.


Surface water monitoring indicates no significant impacts to surface water quality based on monitoring results.


All potentially contaminated water will be collected and treated prior to discharge.

All working areas will be designed to meet surface-water quality



criteria that will be agreed with DTAE as part of the Construction EMP.







– Sewage and grey water produced at the Site Yard will be collected and disposed of at a facility appropriately approved for that purpose.





– Stormwater detention basins will be constructed to collect site runoff and minimise the direct release of stormwater from the



site.



Any water pumped or drained from excavations will be filtered through a suitable medium (straw bales, break tank, geotextile membrane, or settling pond) prior to being disposed of to vegetated land. There will be no direct discharge of silty water to watercourses.

Cut off drains will be installed to divert all natural drainage lines around the landfill.








Monitoring All monitoring will compare results against the stated standards (Section 4).

No baseline monitoring has been carried out to date, as all the surface-water in proximity to the landfill is ephemeral in nature. If the opportunity arises (e.g. after a significant rainfall event), baseline monitoring will be carried out. As a minimum, pH, total dissolved solids and hydrocarbons will be analysed.

Visual inspections will be carried out regularly at the Site Yard and landfill site, to monitor silty water run-off. Fuel storage and refuelling areas will also be inspected to ensure correct procedure is being adhered to at all times.

Given the ephemeral nature of surface-water, water quality monitoring will be repeated only if there is reason to believe contamination has



occurred because of related activities.

3.5.3 Air Quality

The dominant emission sources in the area surrounding the landfill site are an aluminium smelter, a ferroalloy plant and a gas fired power station. Emissions from the Bell Bay Industrial Estate include sulphur dioxide, nitrogen dioxide, particulate matter and hydrogen fluoride.

Air quality impacts from construction of the landfill could potentially occur by:

Mitigation Actions All design and drawings will comply with this MMP and EMP (Design).


Water spraying will be utilised as required (that is, when in close proximity to sensitive vegetation) to dampen dust on working areas and/or access tracks.



Speed limits will be reviewed during extended periods of dry weather to minimise dust generation.


When travelling on gazetted public roads, loads on haul trucks will be covered to minimise dust emissions.

The landfill has been designed to allow for the progressive rehabilitation and revegetation of cells as soon as they have reached


3. Air Quality

capacity. Vegetative cover will help bind the surface soil and reduce dust emissions.








Visual inspections of sensitive vegetation will be carried out regularly to monitor dust levels.



A complaints register will be maintained in order to identify any areas where dust is a significant problem.

3.5.4 Noise

The proposed new landfill site is located away from any residents or other sensitive receptors.

4. Noise








Where appropriate, noise barriers will be erected between sensitive receptors and construction operations (including welfare facilities for


4. Noise

construction workers), e.g. cladding, soil mounds or straw bale barriers around pumps and generators.

Where practicable, excessive noise generating activities will be undertaken during daytime operating hours.


Local residents will be informed in advance of any particularly noisy operations, e.g. blasting.


Construction employees will be supplied with hearing protection as required and will be provided with training on the importance of its use. Areas where the use of hearing protection is required will be clearly signposted.

A noise management strategy will be prepared prior to the quarry becoming operational.







Monitoring Due to the lack of sensitive receptors in proximity to the landfill site, noise monitoring is not considered necessary.

Targeted noise surveys will be carried out in the event of complaints being received. The nature of the complaint will determine the noise monitoring strategy to be employed.

Reporting and Review If complaints are received and noise monitoring becomes necessary,

reporting and review procedures will be developed at that time.



The majority of the soils at the landfill site are class 6 (Volume 3, Section 2.6.2), which is characterised as having a high risk of erosion.

Construction of the landfill may result in erosion and subsequent sediment release to the surrounding environment for the following reasons:


Topsoil and subsoil will be stockpiled in mounds, making it susceptible to wind and water erosion; and

Inadequate compaction during backfilling and weakened soil structure may make the soils more susceptible to water erosion, forming gullies.







Limit the total area of disturbance, or ‘project footprint’ to the minimum required for the project. The landfill design is based on a progressively construction of cells only if and as they are required.


– Safeguarding of topsoil by stripping and stockpiling prior to construction.



– Erosion control structures such as diversion banks and berms will be designed to limit topsoil movement as necessary.

– Topsoil stockpiles will be designed to prevent excessive loss by wind and water erosion.

– Erosion and sediment control measures will be installed in



high-risk areas.

– Pre-construction drainage will be installed where necessary. Drainage outfalls will be designed to divert flow and control runoff, and ensure adequate scour protection. This may include utilising riprap (rocks held with wire mesh), revegetation and/or geotextile material.

Install pre-construction drainage where necessary. Design drainage outfalls to divert flow and control runoff, and ensure adequate scour protection. This may include utilising riprap (rocks held with wire mesh), revegetation and/or geotextile material.


Standard N/A



Monitoring Compaction tests will be carried out at regular intervals during backfilling, to ensure soil compaction ranges 90% and 110% of the compaction of adjacent undisturbed soils. A record of all compaction tests will be maintained.


Monthly site inspections will be carried out on completion of construction, for a period of time that will encompass autumn and winter (that is, periods of high rainfall). The physical extent of erosion (rills and gullies) will be noted and, if the erosion does not stabilise, remedial earthworks will be undertaken.





A range of potential direct and indirect impacts are relevant to the construction and ongoing operation of the pulp mill. These impacts may be direct or indirect, adverse or beneficial, short or long term, temporary or irreversible. Construction of the landfill may affect terrestrial flora and fauna in the following ways:


Loss of native vegetation within the 14ha site, the Site Yard and associated access tracks. This includes clearance of vegetation of conservation importance (Shrubby Eucalyptus ovata-E. viminalis forest);

Loss of habitat for terrestrial fauna (both temporary and permanent);


Loss of or damage to plant species of state significance, Pimelea flava;



Altered fire and/or grazing regimes that can change species composition.








– Limit the clearing of vegetation to that essential for the project (during design this applies to the ‘footprint’ of disturbance). The landfill design is based on a progressively construction of cells only if and as they are required.

– Where practicable, locating the Site Yard and other project facilities to avoid sensitive habitats or areas known to support protected species.

– Installation of fencing in areas that are within the development footprint but that are planned for non-disturbance.

– Designing night-lights so that they are not directed onto sensitive habitat areas. Light spillage will be limited as much as possible.

– Rehabilitation of disturbed areas of the site which are not required for ongoing mill operations to minimise the total amount of permanent habitat loss.

– Fauna inhabiting the area will be allowed to relocate naturally. Construction crews will be educated about the management of fauna (eg. not to take fauna including snakes).





– Topsoil stripped from the site will be stockpiled separately from subsoil and used for rehabilitation, where practicable. Topsoil stockpiles will be protected from erosion and waterlogging to ensure the natural seed bank stored in the soil remains viable.

– Where practicable, on completion of the works, disturbance of rehabilitated areas will be minimised by fencing to facilitate revegetation.



Development of a Rehabilitation Management Plan for the quarry site (in accordance with the Quarry Code of Practice) and for the landfill site.

Establishing the extent (if any) of Phytophthora cinnamomi, installing wash facilities to prevent its introduction and using reliable, clean sources for gravel and other fill materials. Restrict access to known infected areas and restrict construction to summer months wherever possible, as the pathogen is less likely to spread in dry conditions.

Developing a fire management strategy that takes into account the regenerative requirements of the species present while still aiming to protect assets and limit the encroachment of shrubs into areas of remnant grassland. The location of firebreaks will be minimised and carefully selected. Where practicable, firebreaks will consist of slashed vegetation, not bare earthen boundaries.

Where appropriate maintaining native herbivore grazing regimes in order to maintain open grass swards and high species diversity.

Considering the development of habitat offsets elsewhere, to compensate for the loss of vegetation on site.

The general hierarchy of waste management principal will be applied to all general waste generated by the pulp mill project. During the construction period, the new landfill will accept inert non-recyclable construction waste only, which will be disposed of into a dedicated cell. Putrescible and hazardous construction waste will be disposed of to a suitably licensed Municipal facility.





Spread of weed through the disposal of green waste;











A licensed contractor will be used for all hazardous and putrescible waste removed from site. Waste Tracking Certificates will be

Hazardous materials will not be permitted at the landfill.


Procurement of materials brought on site will consider the amount of waste generated, and consideration will be given to reducing this at the procurement stage. Consideration will also be given to the cost of waste disposal, any necessary pre-disposal treatment required and the risk of contamination.

Where necessary, waste will be stored in appropriate containers and protected from adverse weather and vermin. All waste disposal containers will be clearly labelled.




Trucks carrying waste to the landfill will if necessary (subject to the nature of the waste being transported in any given load) be covered with tarpaulin to minimise the risk of escape and dust.

3.5.10 Social, Land Use and Economics

The proposed landfill site is located within the Bell Bay Industrial Area, which has long been accepted by local residents as an area of heavy industry. The site was one of three preferred sites for a new landfill identified by the (then) Department of Environment and Land Management. Gunns selected the proposed site over the other two primarily due to its lower visibility potential. The site is located in a depression in the lower Tippogoree Hills, below the ridgeline.

3.6 Environmental Management Plan - Water Supply Pipeline

This MMP applies to construction of the pulp mill water supply pipeline and associated infrastructure (pumps, etc) only. Construction of the pipeline has the potential to impact on the natural, social and cultural environment in a number of ways, as described in Volume 3. The EMP (Planning) summarises the mitigation measures proposed to control detrimental impacts and provides the outline of a monitoring strategy to assess the success of the mitigation measures. The Alliance will develop an EMP (Construction).

Where appropriate, construction of the water supply pipeline will be consistent with the Australian Petroleum Industry Association (APIA) Code of Environmental Practice.

The Alliance will establish and maintain a Site Yard in proximity to the pipeline route, with equipment lay-down areas, working areas, facilities for refuelling, waste management, and storage of chemicals. It will be the responsibility of the Alliance to identify a suitable location (taking into account the requirements of the EMP) and to negotiate the lease for such a site with the relevant landholders. The Alliance will also rehabilitate the Site Yard where appropriate.


The baseline environmental data for the water supply pipeline route (Volume 3) indicates that groundwater is generally of good quality, with low salinity. It is suggested that it is suitable for both domestic and livestock uses. The water table is high, at approximately 3m. Aquifers are unconfined and moderately susceptible to pollution (although this will vary somewhat along the pipeline route).

Construction of the water supply pipeline has the potential to affect groundwater if contaminants such as those listed below migrate down through the soil horizon and reach the water table:


Chemicals such as paint; and

Liquid wastes including oily water from drip trays, sewerage and grey water from the Site Yard and any additional welfare facilities along the route.







All working areas will be designed to meet the groundwater quality standards in Section 4. As a minimum design of working areas will include:

– Dedicated fuel and chemical storage areas that meet the



requirements of AS 1940, and are appropriately signed with content and volume. The storage areas will be sited in locations that pose low risk to any watercourses or bores. All storage areas will be bunded and all associated infrastructure (that is, hoses, pipework, etc) will be contained in accordance with the relevant Australian Standard. All bunds will contain an oily water interceptor and sump.



– All fixed plant will be equipped with drip trays. Drip trays will be checked after significant rainfall events, and any oily water will be collected and disposed of in such a way that prevents contamination of groundwater. (




In areas where there is a potential risk of the pipeline trench intercepting the water table (e.g. on the floodplain of the River Tamar), it may be necessary to install clay plugs or similar at regular intervals within the trench to prevent the pipeline route acting as a preferential pathway for groundwater flows. This method of control will also be utilised in the event that the pipeline passes through areas of previously contaminated land.



Ongoing comparison with Groundwater Quality Standards (in the absence of baseline data) (Section 4).





State Policy of Water Quality Management, 1997.





During construction of the water supply pipeline, groundwater quality monitoring will be undertaken if there is reason to suspect contamination has occurred.













No groundwater abstraction is permitted for construction of the water supply pipeline, this is inclusive of hydrotesting.



The water supply pipeline will cross a number of watercourses, the most significant of which is the Tamar River. The latter will be crossed using a jet trenching technique. However the smaller watercourses are expected to be crossed using an open cut methodology or piers.

Construction of the water supply pipeline has the potential to impact on surface-water quality on or off-site if contaminants such as those listed below are accidentally released and are not sufficiently contained:



Liquid wastes including sewage and grey water from the Site Yard and any additional welfare facilities along the route;


Sediment-laden water released from the pipeline trench during dewatering and over-pumping.







Existing water allocations from Hydro-Tasmania will be utilised.

All potentially contaminated water must be collected and treated prior to discharge.

All working areas will be designed to meet surface-water quality criteria that will be agreed with DPIW as part of the Construction EMP.






Cut off drains will be installed to divert all natural drainage lines around the landfill.

All watercourse crossings will be rehabilitated on completion of the construction works. Rehabilitation design will be undertaken with reference to the pre-construction flora and fauna surveys.










Surface water quality-monitoring will be carried out at all watercourses to be crossed by the pipeline prior to construction commencing, in order to establish a baseline measurement. The following components will be analysed as a minimum:

– pH;

– Total Suspended Solids; and

– Hydrocarbons.

During construction of the Tamar River crossing, a weekly water quality monitoring program near the crossing will be initiated.

Additional analyses will also be carried out for watercourse crossings other than the Tamar River in the event of significant rainfall occurring during construction of the crossing or if there is reason to believe contamination has occurred e.g. if there has been a significant spill.

Sampling will be carried out at all watercourse crossings on completion of the works.



Should any parameters fall outside of the stated water quality standards (Section 4) or differ by 10% or more from the baseline measurement. The EMP (Construction) and the investigation threshold will be reviewed and amended as necessary.












3.6.3 Air Quality

The dominant emission sources in the pipeline corridor are from Launceston based industries, domestic fuel heaters and vehicles in the southern sector and Bell Bay industries in the northern sector. Emissions from these industries include sulphur dioxide, nitrogen dioxide, particulate matter and hydrogen fluoride.

Air quality impacts resulting from construction of the water supply pipeline have the potential to occur by:

3.6.4 Noise

The primary noise source from the proposed water supply pipleing is from the physical constructtion activities. The construction process will included works close to residential dwellings and subsequent noise impacts may occur. These noise impacts will be from eartmoving machinery and engineering of the pipeline.

4. Noise







Modern construction equipment that utilises built-in noise abatement equipment will be used. Regular servicing and maintenance of plant will be undertaken to ensure optimum performance.

Where appropriate, noise barriers will be erected between sensitive receptors and construction operations (including welfare facilities for construction workers), e.g. cladding, soil mounds or straw bale barriers around pumps and generators.

Normal construction hours will be 7am to 6pm Monday to Friday and 8am to 4pm on Saturday and Sunday. All work outside of these hours will require approval in advance by the appropriate authority, and will need to comply with the stated noise limits.

All plant and machinery will be turned off when not in use. Equipment found to be noise in excess of the EMPCA Noise Regulations will be taken out of use, and repaired or removed from site.


Supply personnel with hearing protection as required and provide training on the importance of use.


4. Noise







Monitoring Noise monitoring may need to be further modified to meet possible licence requirements, and if complaints are received from nearby residences.

Reporting and Review A log sheet of recorded noise readings will be maintained, and the

results compared to the baseline noise levels and noise limits in Section 4. Non-compliances will be reported, as well as the remedial action taken to address the issue.



The majority of the land crossed by the water supply pipeline is class 6 (Volume 3, Section 2.6.2), which is characterised as having a high risk of erosion.

Construction of the water supply pipeline may result in erosion along the alignment and subsequent sediment release to the surrounding environment for the following reasons:


Topsoil and subsoil will be stockpiled in mounds while the pipe is being laid, making it susceptible to wind and water erosion; and

Inadequate compaction during backfilling and weakened soil structure may make the alignment more susceptible to water erosion, forming gullies.

These issues may be exacerbated on side slopes along the pipeline route.




Performance Sediment load monitoring and environmental audits indicate no

significant impacts from erosion.



Construction impacts of the pump station will be minimised by conducting works during regular maintenance events for the Trevallyn Dam.

Utilise jet trenching construction methods to minimise impacts on Tamar River crossings.







– Ensure that erosion and sediment control measures are constructed in high-risk areas.

– Install pre-construction drainage where necessary. Design drainage outfalls to divert flow and control runoff, and ensure adequate scour protection. This may include utilising riprap (rocks held with wire mesh), revegetation and/or geotextile material.

Install pre-construction drainage where necessary. Design drainage outfalls to divert flow and control runoff, and ensure adequate scour protection. This may include utilising riprap (rocks held with wire mesh), revegetation and/or geotextile material.




Standard N/A





The alignment will be inspected on a monthly basis on completion of construction, for a period of time that will encompass autumn and winter (that is, periods of high rainfall). The revegetation and physical extent of erosion (rills and gullies) will be noted and, if the erosion does not stabilise, remedial earthworks will be undertaken.

The monitoring program will be developed further prior to construction commencing.




Construction of the water supply pipeline may affect terrestrial flora and fauna in the following ways:

Loss of or damage to native vegetation (including ecologically threatened communities) along the 20m working width and at the Site Yard, pump station location and associated access tracks.;




Noise, vibration, light and dust impacts on local flora and fauna; and

Potential introduction and/or spread of weeds, pest species and diseases such as Phytophthora cinnamomi to the site.








Minimise clearing and maintain screening where possible.



– Rehabilitation of disturbed areas of the site where no permanent structures are to be installed, to minimise the total amount of permanent habitat loss.



– Ongoing ecological assessment should be undertaken internally by appropriate staff to ensure a detailed understanding of local landscape processes, which may affect ultimate restoration success.


– On completion of the works, disturbance of rehabilitated areas will be minimised by fencing to facilitate revegetation.


Establish the extent (if any) of Phytophthora cinnamomi, install wheel wash facilities to prevent its introduction and use reliable, clean sources for gravel and other fill materials.. Restrict access to known infected areas and restrict construction to summer months wherever possible, as



the pathogen is less likely to spread in dry conditions.

Where appropriate maintain native herbivore grazing regimes in order to maintain open grass swards and high species diversity.



Standard Environment Protection and Biodiversity Conservation Act, 1999 (Cth).












The general hierarchy of waste management prinicpal will be applied to all general waste generated by the pulp mill project. The majority of non-recycable waste produced during construction of the water supply pipeline will be stored on site, in readiness for later disposal at the new landfill site. This landfill will accept inert and non-hazardous waste only. Hazardous waste and putrescible waste will be disposed of to a suitably licensed Municipal facility.






Spread of weed through the introduction of weed;











A licensed contractor will be used for all waste to be removed from site. Waste Tracking Certificates will be completed for all regulated waste and kept in the site offices as part of the project Environmental Record. Non-regulated waste will not be tracked However a log of all waste types produced will be maintained, along with approximate quantities generated.








All personnel will be provided with training on waste management



Environmental Management and Pollution Control (Waste Management) Regulations, 2000.











Construction of the water supply pipeline and associated facilities will require the storage and use of various hazardous materials. Examples include fuel, hydraulic oil and paint.










Fuel and chemical storage areas will be bunded according to AS1940 to contain any potential spills. They will not be located immediately adjacent to any surface-water or bores.


Storage areas will be clearly labelled with the quantity and characteristics of the chemical stored. Manufacturers’ Material Safety Data Sheets (MSDS) will be available which indicate the appropriate action to be taken in the event of a spill.




















A combination of desk-based assessment and field surveys has identified that there are six known sites of Historic heritage significance along or within the vicinity of the water supply pipeline alignment. There are three known sites of Aboriginal heritage significance, located at the Tamar river crossing, East Arm and near Mount Direction.

The preferred alignment of the water supply pipeline does not result in impacts on any identified sites of Historic Heritage Significance.



To ensure there are no negative impacts on the region’s cultural heritage values at or adjacent to the project sites.


No complaints are received with concerning cultural heritage from the local or regional communities.













Prior to construction, undertake field surveys along those parts of the alignment that were not previously surveyed due to access restrictions.

Route the pipeline to avoid the three known sites of Aboriginal heritage significance. If avoidance is not possible, written permission from the Minister must be obtained, prior to a suitable qualified and experienced Aboriginal Heritage Officer relocating the artefacts to an alternative site.

Monitoring by an Aboriginal Heritage Officer will be undertaken whilst undertaking works on the section of pipeline between Coulsons and Station Creeks at Dilston.

Conduct community consultation process with Tasmanian Aboriginal Land and Sea Council (TALSC), and with any other potentially affected people prior to construction commencing.

Sites that are to be avoided will be designated as prohibited areas and cordoned off and flagged, to ensure they are not destroyed or affected. Construction crews will be informed of their importance.

3.6.10 Social, Land Use and Economics

Potential socio-economic impacts that may arise because of construction of the pipeline include the following:

Visual impacts including light pollution

Potential problems arising between the landholders with regard to construction impacts.

Pressure on local services and infrastructure.



To realise economic and social benefits of the project while minimising negative impacts on the local community and businesses.




Develop an agreement with landowners to allow for the pipeline location and access.

Develop a site specific traffic management plan.

Encourage job applicants from local communities.



Facilitate employment opportunities and ease of employment (that is, transport to working areas) for local workers.



Existing sealed roads will be crossed using a non-open cut technique (auger boring) to minimise disturbance to road users.

Working areas will be fenced off to ensure farmers and livestock do not access the pipeline works.

Restrict rock blasting to times which will have minimal impact on the local community.

Inform residents of blasting events/times.

Locate Site Yards to minimise impacts on residential areas.

Where possible, local and regional businesses will be supported by:

– Using local content of the workforce where possible; and

– Providing training for the workforce on site.

Pipeline alignment will be restored as close as possible to its pre-construction conditions to support the original or similar land use, however the easement must remain clear of medium to tall woody vegetation.

3.7 Environmental Management Plan - Effluent Pipeline and Ocean Outfall

This MMP applies to construction of the pulp mill effluent pipeline and associated ocean outfall only. Construction of the pipeline and ocean outfall has the potential to impact on the natural, social and cultural environment in a number of ways, as described in Volume 3. The EMP (Planning) summarises the mitigation measures proposed to control detrimental impacts and provides the outline of a monitoring strategy to assess the success of the mitigation measures. The Alliance will develop an EMP (Construction).Construction of the effluent pipeline will be consistent with the Australian Petroleum Industry Association (APIA) Code of Environmental Practice.

The Alliance will establish and maintain a Site Yard in proximity to the pipeline route, with lay-down areas, working areas, facilities for refuelling, waste management, and storage of chemicals. It will be the responsibility of the Alliance to identify a suitable location for additional Site Yards should they be required (taking into account the requirements included in the EMP) and to negotiate the lease for such a site with the relevant landholders. The Alliance will also rehabilitate the Site Yard.


The baseline environmental data provided in Volume 3 indicates the presence near Five Mile Bluff of aquifers with groundwater quality suitable for most uses and with high susceptibility to pollution, except in areas where the aquifer is overlain with a layer of low permeability, e.g. clay. The quality of the groundwater is likely to be more potable progressively inland, although the extensive use of fertilisers on farms may diminish water quality. The migration of saline seawater into the aquifer is naturally prevented by the recharge of freshwater in inland areas and the coastward flow of this water.

Construction of the effluent pipeline and ocean outfall has the potential to impact on groundwater if contaminants such as those listed below migrate down through the soil horizon and reach the water table:


Chemicals such as paint, asphalt, etc.;

Liquid wastes including oily water from drip trays, sewerage and grey water from the Site Yard and any additional welfare facilities along the route; and

Drilling and auguring muds.

















, As far as practicable, trenching in the swales between sand dunes will be undertaken during the dry season to prevent the influx of saline water into the fresh groundwater system.







State Policy of Water Quality Management, 1997.





During construction of the effluent pipeline, groundwater quality monitoring will be undertaken if there is reason to suspect contamination has occurred eg in the event of a significant spill.













Other than dewatering to prevent saline intrusion into aquifers, no groundwater abstraction will be permitted for construction of the effluent pipeline; this is inclusive of hydrotesting.



The effluent pipeline will cross five watercourses (Appendix D of Effluent Pipeline Design Basis Report, Hargrave Pipeline Group, 2005). Most of the streams in the region are ephemeral, with strong flow mainly occurring only in the winter months and after summer storms. The drainage of water in the coastal plain is predominantly through broad, shallow, seasonally intermittent creeks that occur in swales between dunes or dune sets.

Construction of the effluent pipeline has the potential to impact on surface-water quality on or off-site if contaminants such as those listed below are accidentally released and are not sufficiently contained:



Liquid wastes including sewage and grey water from the Site Yard and any additional welfare facilities along the route;

Sediment-laden run-off from construction work sites;

Sediment-laden water released from the pipeline trench during dewatering and over-pumping; and

Drilling and auguring muds.















– All fixed plant will be equipped with drip trays where appropriate. Drip trays will be checked after significant rainfall events, and any contaminated water will be collected and disposed of at a facility appropriately approved for that purpose













All watercourse crossings will be rehabilitated on completion of the construction. Rehabilitation design will be undertaken with reference to the pre-construction flora and fauna surveys.




State Policy on Water Quality Management 1997.

EMP (Design), Section 3.5.1, Ground Water MMP.



Monitoring All monitoring will compare results against stated standards (Section 4).


Surface water quality monitoring will carried out at all watercourses to be crossed by the pipeline prior to construction commencing, in order to establish a baseline measurement. The following components will be analysed as a minimum:

– pH;


– Hydrocarbons.

During construction of the watercourse crossings, water quality monitoring will be undertaken only after significant rainfall events or if there is reason to be contamination has occurred e.g. in the event of a major spill.

Water quality monitoring will be undertaken at all watercourse crossings on completion of the works and compared to the baseline measurements.



Should any parameters fall outside of the stated water quality standards (Section 4), the EMP (Construction) will be reviewed and amended as necessary.












3.7.3 Marine/Offshore Water Quality

Contaminants enter Bass Strait directly and via the Tamar estuary from a variety of point and diffuse sources, including treated sewage, industrial effluent, urban run-off, atmospheric and groundwater pollution, ballast discharges and run-off from agriculture, forestry and mining within the catchment. These contaminants are rapidly diluted as they enter the Bass Strait but may remain there for one or two tidal cycles. Metal concentrations in estuary water, sediments and biota (particularly of zinc and cadmium) have been known to exceed recommended guidelines.

The effluent pipeline will terminate in a 3 km offshore outfall from Five Mile Bluff, with a multi-point diffuser system. Currently the preferred construction methodology for this is to dredge, lay (bottom-tow) and backfill; this will be confirmed during the detailed design stage.

Construction of the outfall may adversely affect marine habitats through the release of sediment during dredging activities and the potential release of contaminants such as fuel and hydraulic fluid. The location of the outfall has been planned to consider the location of ecologically sensitive areas such as high and low profile reefs.


3. Marine/Offshore Water Quality


To limit the risk of contamination and potential impacts to marine waters of the surrounding environment.


Hydrodynamic modelling and sediment analysis will be conducted and the results analysed to ensure there is no irregular stratification of offshore waters or adverse impact to marine flora/fauna – outside of a defined mixing zone.


All work methodologies, storage and equipment will be designed to meet the marine (offshore) water quality standards for discharge (Section 4).

Ensure that the detailed design locates the outfall and multi-point diffuser away from:

– existing fixed installations (e.g. underwater cables and pipelines); and

–

– Identified ecologically sensitive areas (e.g. high diversity reefs).

Design to maximise dispersal and mixing from the outfall.

In the event that blasting is required, the resulting wave action will ensure that any sediment that resettles in the intertidal zone is redistributed to conform to the surrounding sand surface.

Low toxicity additives will be used if hydrotest waters will need to be discharged into Bass Strait. The water will be discharged as far offshore as practicable, and in a way that maximises mixing. Additional dilution will be provided if required.

The Site Project Manager will prepare a Dredging Management Plan which will incorporate the following:

– The location of dredge-spoil storage areas offshore will include an assessment based on ecological sensitivity.

– Dredge material will be placed as near as practicable to the pipeline trench, and subsequently reused to cover the pipeline.

. All pipe laying and excavation works within Donovans Bay (Tamar Estuary) that have the potential to result in mobilisation of sediments will be carried out in the first two-thirds of outgoing tides. This will provide maximum downstream movement and dilution of mobilised contaminants.



Discharge (that is, hazardous materials, oil, untreated shipboard effluent, wastes and refuse) from the pipe-laying vessel to coastal waters will be prohibited. Discharge products will be retained on-board and disposed of at appropriate onshore facilities.

Ballast sludge will not be discharged to the sea, nor will any ballast water that does not meet the discharge criteria in Section 4.

The pipe-laying vessel will be equipped with appropriate spill response equipment (including, but not limited to a floating boom, skimmers and absorbent materials) to be used to prevent the spread of contaminant will any spills occur. The use of dispersants will be prohibited, except with the provision of expert advice, as these products frequently result in greater impacts on pelagic and benthic species in shallow environments.

All crew on the pipe-laying vessel will be trained in spill response methods for marine waters.

Drip trays will be used under all fixed plant on the pipe-laying vessel.


Ongoing comparison with Marine/Offshore Water Quality Standards (Section 4).

Standard EMP (Design), Section 4, Marine/Offshore Water Quality Standards.

State Coastal Policy, 1996.





Marine water quality will be monitored prior to commissioning as a baseline measurement, monthly over the duration of construction activities, and upon completion final activities.

As a minimum, parameters measured will include:

– Hydrocarbons

– Total Suspended Solids.














3.7.4 Air Quality

The dominant emission sources in the effluent pipeline corridor area are from an aluminium smelter, a ferroalloy plant and a gas-fired power station. Emissions from the Bell Bay Industrial Estate include sulphur dioxide, nitrogen dioxide, particulate matter and hydrogen fluoride (Volume 3).

Air quality impacts resulting from construction of the effluent pipeline and outfall discharge point have the potential to occur by:



4. Air Quality


To limit the release of harmful air pollutants into the surrounding air shed.


Air emissions from the works do not cause significant impacts outside of the site boundaries from dust, air particulates, odour, smoke and fumes.


4. Air Quality







Loads on haul trucks will be covered if necessary (subject to the nature of the load being carried) to prevent dust emissions.

The pipeline route will be rehabilitated and revegetated as soon as practicable following completion of construction. As for other pipeline.

Natural re-vegetation may be enhanced by the use of targeted seeding programmes in areas of high risk of wind erosion, e.g. dune systems.


Standard Section 4, Air and Noise Quality Standards




Monitoring Monitor by exception as per previous.


Community liaison (including a record of any complaints) will reveal any areas of particular concern.




3.7.5 Noise

The primary noise source from the proposed effluent pipeline is from the physical construction activities. The construction process will include works close to residential dwellings and subsequent noise impacts may occur. These noise impacts will be from earthmoving machinery and engineering of the pipeline.

5. Noise








When appropriate noise barriers will be erected between sensitive receptors and construction operations, e.g. cladding, soil mounds or straw bale barriers around pumps and generators.

Normal construction hours will be 7am to 6pm Monday to Friday and 8am to 4pm on Saturday and Sunday, excluding the outfall which will be 24 hour during the launching phase.


Local residents will be informed in advance of any particularly noisy operations, e.g. blasting.

Construction employees will be supplied with hearing protection as required and provided training on the importance of its use. Areas where the use of hearing protection is required will be clearly signposted.

Noise arising from construction of the marine outfall may disturb marine fauna, including sea birds.

As far as practicable, construction will avoid sensitive seasons such as shark pupping.


5. Noise

Throughout construction, crews will be alerted to the presence of whales, dolphins, seals, turtles and other migratory species and the use of noisy equipment will then be limited.

Monitoring Noise monitoring may need to be undertaken if complaints are received from nearby residences.





The Quaternary sands of the coastal dunes and beaches are highly susceptible to wind erosion. Inland, sheet erosion is a risk on elevated areas, particularly where dolerite occurs on steeper slopes.

Construction of the onshore component of the effluent pipeline and outfall may result in erosion along the alignment and subsequent sediment release to the surrounding environment for the following reasons:


Topsoil and subsoil will be stockpiled in mounds while the pipe is being laid, making it susceptible to wind and water erosion;

Inadequate compaction during backfilling and weakened soil structure may make the alignment more susceptible to water erosion, forming gullies; and

Sand dunes will need to be trenched through, making them vulnerable to blow outs

These issues may be exacerbated on side slopes along the pipeline route.

The sediments near the multi-port diffuser consist predominantly of coarse sand. These areas are more exposed to agitation by wave action than areas where the sediments are interspersed with patches of


reef. Construction of the offshore component of the effluent pipeline will result in the release of sediment from dredging and blasting activities and potential increased susceptibility to erosion.











– As far as practicable, land will be progressively disturbed during construction to ensure minimum exposure to the influence of weather conditions (eg. rainfall and wind).



– Erosion and sediment control measures will be installed in high-risk areas.

– Pre-construction drainage will be installed where necessary. Design drainage outfalls will be designed to divert flow and control runoff, and ensure adequate scour protection. This may include utilising riprap (rocks held with wire mesh), revegetation and/or geotextile material.

Installation of the effluent pipeline through the dune systems has the potential to result in inland movement of disturbed sand. Additional mitigation measures may be required, such as:

– Minimise disturbance of unconsolidated or semi-consolidated materials, for example by using shoring and battering to reduce



the width of trenches through the dunes.

– the excavation associated with the dune crossing of the pipeline will remain open for the minimum amount of time practiciable.

– Hessian fencing (or similar mesh fencing) installed around working areas to limit the movement of sand.

– Stockpiles of excavated material covered with geotextile to minimise loss of sand by wind erosion.

– Stabilisation of areas as soon as backfilling is complete. This may require temporary stabilisation measures to be used until final reinstatement can be carried out.

– Rehabilitate areas as soon as they are stabilised, as vegetative cover will assist to bind the surface of the sand.


Standard N/A





The alignment will be inspected on a monthly basis on completion of construction, for a period of time that will encompass autumn and winter (that is, periods of high rainfall). The physical extent of revegetation and erosion (rills and gullies) will be noted and, if the erosion does not stabilise, remedial earthworks will be undertaken.

The monitoring program will be developed further prior to construction commencing and will incorporated into the Construction EMP. This will include ongoing monitoring of the dune stability associated with the shoreline face.





Construction of the effluent pipeline may affect terrestrial flora and fauna in the following ways:

Loss of or damage to native vegetation along the 20m easement, at the Site Yard, access tracks, etc., including ecologically threatened communities;



Loss of or damage to species of national or state significance;











– Where practicable, locating the Site Yard and other project facilities to avoid sensitive habitats or areas known to support protected species.

– Rehabilitation of disturbed areas of the site which are not required for ongoing mill operations, to minimise the total amount of permanent habitat loss.

– Fauna inhabiting the area will be allowed to relocate naturally. Construction crews will be educated about the management of fauna (that is, not to kill fauna including snakes).







A Remediation and Revegetation Plan will be prepared.



Establishing the extent (if any) of Phytophthora cinnamomi, installing wheel wash facilities to prevent its introduction and using reliable, clean sources for gravel and other fill materials. Access to known infected areas will be restricted and construction will be restricted to summer months wherever possible, as the pathogen is less likely to spread in dry conditions

Where appropriate maintaining native herbivore grazing regimes in order to maintain open grass swards and high species diversity.

Considering the development of habitat offsets elsewhere, to compensate for the loss of vegetation on site.


Standard Environmental Protection and Biodiversity Conservation Act, 1999 (Cth).

On completion of the construction works, monthly visual inspections of the rehabilitated areas will be carried out, for a period of time that



will encompass autumn and winter (that is, the period of highest rainfall).





3.7.8 Marine/Offshore Flora and Fauna

The proposed marine outfall is located within the Boags marine bioregion, which is characterised by several species (such as the seagrass Posidonia) not generally found further south in Tasmania. A survey carried out by Aquenal Pty Ltd in 2005 in the vicinity of the outfall identified approximately 100 to 110 species.

Impacts to marine flora and fauna will be primarily associated with the dredging of the outfall trench. Sound engineering design (e.g. location of the outfall pipes and multi-port diffuser) and selection of appropriate construction techniques will limit potential impacts on marine flora/fauna.



To constrain the negative impacts on the marine flora and fauna habitat of communities potentially affected by the project.




Marine habitats have been mapped in detail and will be considered prior to construction to ensure the location of the outfall does not encroach on rocky reefs or areas of seagrass, as far as reasonably practicable. A bathometric survey has been completed and will also be used for this purpose.

Where practicable dredging activities are to be undertaken outside times of ecological sensitivity (that is, considering breeding cycles of key species, coral spawning etc.).

The use of a silt curtain is not currently thought to be feasible due to the perceived currents. However this option may be explored further, with the provision of metocean data.



Fauna inhabiting the area will be allowed to relocate naturally. Construction crews will be educated in fauna management (that is, not to take fauna).


Standard Threatened Species Protection Act, 1999

Monitoring A benthic fauna/flora monitoring program will be developed and implemented immediately before and after initial dredging or offshore spoil disposal events.

Other monitoring procedures will be developed prior to construction.






Waste produced during construction of the effluent pipeline that cannot be recycled or reused will be disposed of in a dedicated construction waste cell at the new landfill site that Gunns will open as part of the overall pulp mill project. This cell will accept inert waste only. Hazardous waste and putrescible waste will be disposed of to a suitably licensed Municipal facility.

Inadequate waste management can result in the following impacts:

Operations Monitoring indicates no significant impacts to the surrounding environment.


A licensed contractor will be used for all hazardous waste to be removed from site. Waste Tracking Certificates will be completed for all regulated waste and kept in the site offices as part of the project Environmental Record. Non-regulated waste(including construction waste) will not be tracked. However a log of all waste types and quantities produced will be maintained along with approximate quantities generated.
















A waste log will be established and kept up to date with for each waste stream produced. The log will record quantities of waste re-used, recycled, treated and disposed of. These will be compared to the waste management KPIs to be set during the detailed design stage.






Construction of the effluent pipeline and marine outfall will require the storage and use of various hazardous materials. Examples include fuel, hydraulic oil and paint.






Environmental incident statistics indicates no significant spills have occurred to land or water.


Hazard Identification (HAZID) workshops will be conducted to determine high and extreme risk events for potential contamination in relation to an accident event. Where possible, design will eliminate the risk or reduce it to as low as reasonably practical.




Bunded storage areas will be of sufficient capacity to contain 110% of the potential volume that could be spilt from the largest vessel within the bund. All hoses, valves, and pipework are to be contained within the bund. Bunds will drain to an interceptor and sump.


Spill kits appropriate for the hazardous material spill response will be available at all fuel and chemical storage areas. Personnel will be trained in spill response..

A combination of desk-based assessment and field surveys has identified that there are no known sites of Historic heritage significance along the effluent pipeline alignment, there are two sites of Historic heritage significance in the vicinity of the proposed outfall. There are three sites of Aboriginal heritage significance in the vicinity of the proposed outfall, and an isolated artefact located close to the effluent pipeline alignment at Lauriston Park.





No complaints are received concerning cultural heritage from the local or regional communities.













Carry out field surveys for sites of Aboriginal heritage significance in those areas that have not already been surveyed due to access restrictions.

Locate the outfall to avoid disturbance to the three known sites of Aboriginal heritage significance. If this is not possible, written permission from the Minister will need to be obtained, prior to a suitably qualified and experienced Aboriginal Heritage Officer relocates the artefacts to an alternative site.

Avoid further disturbance to the Lauriston Park artefact by designating it as a prohibited areas, cordoning off the site and advising construction crews of its importance.

Avoid disturbance to the two Historic heritage sites in the vicinity of the proposed outfall.

Avoid culturally significant sites when locating access roads, Site Yard, and associated infrastructure. Additional field surveys will be undertaken if the preferred location for such facilities has not previously been surveyed.

If Aboriginal heritage sites are at risk of disturbance, TALSC and with any other potentially affected members of the Aboriginal community will be consulted prior to construction commencing.

Significant sites will be designated as prohibited areas and cordoned off and flagged to ensure that they are not destroyed or disturbed.

A contingency plan for the event that any previously unknown sites are discovered during construction will be developed. This will include immediate cessation of works, notification of the relevant authorities and further investigation as required.

3.8 Environmental Management Plan - Accommodation Facility

This MMP applies to the construction of the accommodation facility only. Construction of the facility has the potential to impact on the natural, social and cultural environment in a number of ways. The EMP (Planning) summarises the mitigation measures proposed to control detrimental impacts and provides the outline of a monitoring strategy to assess the success of the mitigation measures. The Alliance will develop an EMP (Construction).

The Alliance will establish and maintain a Site Yard in proximity to the accommodation facility, with lay-down areas, working areas, facilities for refuelling, waste management, and storage of chemicals. The Alliance will also rehabilitate the Site Yard where appropriate.


As part of the geotechnical investigation (Appendix 60, Volume 18) groundwater was encountered 0.3 – 1.1 mm below natural surface level.

Latinovic (2002) indicates that the accommodation facility is located over a porous aquifer that is generally high yielding, with groundwater suitable for most purposes. Vulnerability to pollution would be high unless a layer of low permeability material, such as clay, overlies the aquifer.

Construction of the accommodation facility has the potential to impact on groundwater if contaminants such as those listed below migrate down through the soil horizon and reach the water table:


Chemicals such as paint, asphalt, etc.; and

Liquid wastes including oily water from drip trays, sewage and grey water from the Site Yard and any additional welfare facilities at the site.








– Dedicated fuel and chemical storage areas that meet the requirements of AS 1940, and are appropriately signed with content and volume. The storage areas will be sited in locations that pose low risk to any watercourses or bores. All storage areas will be bunded and all associated infrastructure (that is,



hoses, pipework, etc) will be contained in accordance with the relevant Australian Standard. All bunds will contain an oily water interceptor and sump.




– All plant and machinery (particularly hydraulic hoses, fuel lines, etc) will be inspected daily and any faults or signs of wear and tear reported to the Site Foreman for repair as part of a preventative maintenance program.










Monitoring – During construction of the accommodation facility, groundwater quality monitoring will be undertaken if there is reason to suspect contamination has occurred e.g. in the event of a significant spill.


To ensure that the results of the monitoring are valid and defensible, a


1. Groundwater Quality Review set of quality assurance and control procedures has been developed

for this investigation. The procedures are summarised below.











No groundwater abstraction will be permitted for construction of the accommodation facility; this is inclusive of hydrotesting.

3.8.2 Surface Water Quality

With the exception of the northeast corner, drainage from the majority of the site is uncontrolled and leaves the site as overland flow. Surface water from the northeast corner flows towards a storm water pipe running adjacent to SVP Industries and then through that into the town storm water system, which flows towards York Creek and then into York Bay.

There are no streams or creeks running through the site. Surface water pools near the northeast corner.

Construction of the accommodation facility has the potential to impact on surface-water quality on or off-site if contaminants such as those listed below are accidentally released and are not sufficiently contained:



Liquid wastes including sewage and grey water from the Site Yard and any additional welfare facilities along the route; and


Sediment-laden run-off from construction work sites.

2. Surface Water Quality




Surface water monitoring indicates no significant impacts to surface-water quality based on monitoring results…








– All fixed plant will be equipped with drip trays where appropriate. Drip trays will be checked after significant rainfall events, and any contaminated water will be collected and disposed of at a facility appropriately approved for that purpose


– Sewage and grey water produced at the Site Yard will be collected and disposed of at a facility appropriately approved



for that purpose (e.g. at a Municipal WWTP).












State Policy on Water Quality Management 1997.

EMP (Design), Section 3.5.1, Ground Water MMP.







Monitoring of any significant surface water bodies will carried out prior to construction commencing, in order to establish a baseline measurement. The following components will be analysed as a minimum:

– pH;


– Hydrocarbons.

Should any parameters fall outside of the stated water quality standards (Section 4), the EMP (Construction) will be reviewed and amended as necessary.

Water quality monitoring will be undertaken after significant rainfall events or if there is reason to be contamination has occurred e.g. in the event of a major spill.

Water quality monitoring will be undertaken on completion of the works and compared to the baseline measurements.













3.8.3 Air Quality

The dominant emission sources in the pipeline corridor area are from an aluminium smelter, a ferroalloy plant and a gas fired power station. Emissions from the Bell Bay Industrial Estate include sulphur dioxide, nitrogen dioxide, particulate matter and hydrogen fluoride28.

Air quality impacts resulting from construction of the accommodation facility have the potential to occur by:

Monitoring Noise monitoring will be carried out prior to set up of the Site Yard.

During construction of the accommodation facility, spot surveys will be carried out at sensitive locations.

Additional monitoring may be required during particularly noisy activities (e.g. rock breaking).

Monitoring will be undertaken using hand-held or tripod-mounted loggers, recording hourly averages. The analysis of the noise monitoring results will take into account existing background noise levels.






Construction of the accommodation facility may result in erosion and subsequent sediment release to the surrounding environment for the following reasons:


Topsoil and subsoil will be stockpiled in mounds while the facility is constructed, making it susceptible to wind and water erosion; and

Inadequate compaction during backfilling and weakened soil structure may make the alignment more susceptible to water erosion, forming gullies.





Sediment load monitoring and environmental audits indicate no significant erosion.





– In areas where no permanent structures are to be installed, 10-15 cm of topsoil will be replaced to promote vegetation growth. Supplementary seeding with native grasses/pastures (as appropriate) may be utilised in areas of particularly high risk of erosion.

– As far as practicable, land will be progressively disturbed during construction to ensure minimum exposure to the influence of weather conditions (eg. rainfall and wind).



– Erosion and sediment control measures will be installed in high-risk areas.

– Pre-construction drainage will be installed where necessary. Design drainage outfalls will be designed to divert flow and control runoff, and ensure adequate scour protection. This may include utilising riprap (rocks held with wire mesh), revegetation



and/or geotextile material.

Altered fire and/or grazing regimes, which can change species composition.









The Site Project Manager will prepare a Flora and Fauna Management Plan which addresses the following:


– Sensitive siting of Site Yard and other project facilities to avoid sensitive habitats or areas known to support protected species.

– Install fencing in areas that are within the development footprint but that are planned for non-disturbance.

– Designing night-lights so that they are not directed onto sensitive habitat areas. Light spillage will be limited as much as possible.

– Rehabilitation of disturbed areas of the site where no permanent structures are to be installed, to minimise the total amount of permanent habitat loss.
