1 Approval process A Notice of Intent in relation to the proposal was received by the Board of the Environment Protection Authority (the Board) on 21 April 2016. An application for a permit under the Land Use Planning and Approvals Act 1993 (LUPA Act) in relation to the proposal was submitted to Launceston City Council on 27 February 2017. The proposal is defined as two ‘level 2 activities’ under schedule 2 of the Environmental Management and Pollution Control Act 1994 (EMPC Act), being:

• 5(a) Quarries: the extraction of any rock or gravel and producing 5,000 cubic metres or more of product per year; and

• 6(a)(ii) Materials Handling – Crushing, grinding or milling: processing (by crushing, grinding, milling or separating into different sizes by sieving, air elutriation or in any other manner) of rocks, ores or minerals at a rate in excess of 1,000 cubic metres per year.

Section 25(1) of the EMPC Act required Council to refer the application to the Board of the Environment Protection Authority (the Board) for assessment under the Act. The application was received by the Board on 3 March 2017. The assessment has been undertaken by the Director, Environment Protection Authority under delegation from the Board. The Board required that information to support the proposal be provided in the form of an Environmental Effects Report (EER). A draft of the EER was submitted to the EPA for comment prior to its finalisation and acceptance on behalf of the Board. The final EER was submitted to Council with the permit application. The EER was released for public inspection for a 14-day period commencing on 15 March 2017. An advertisement was placed in The Examiner and a notice was placed on the EPA website. The EER was also referred at this time to relevant government agencies for comment. No public submissions were received.

2 SD objectives and EIA principles The proposal must be considered by the Director in the context of the objectives of the Resource Management and Planning System of Tasmania (RMPS), and in the context of the objectives of the Environmental Management and Pollution Control System (EMPCS) (both sets of objectives are specified in Schedule 1 the EMPC Act). The functions of the Board are to administer and enforce the provisions of the Act, and in particular to use its best endeavours to further the RMPS and EMPCS objectives. The Director must undertake the assessment of the proposal in accordance with the Environmental Impact Assessment Principles defined in Section 74 of the EMPC Act.

3 The proposal The proposal, located approximately 28km north-east of the township of Launceston, is for an open-cut quarry to extract up to 100,000mᵌ of rock and clay/silt material. The South Pit will excavate up to 40,000mᵌ clay/silt material to a depth of approximately 3m and screening may be required. The North Pit will excavate up to 56,000mᵌ basalt rock to an approximate depth of 7m. Blasting, crushing and screening may be required in the North Pit. The proposed quarry is a “one off” activity specifically for the construction of the Camden Rivulet Dam as part of developing the Scottsdale Irrigation Scheme (SIS), to service primary production in the local area. The quarry will be rehabilitated after completing the SIS, approximately 18 months from the SIS commencement. The main characteristics of the proposal are summarised in Table 1. A detailed description of the proposal is provided in Section 3.1 of the EER. Table 1: Summary of the proposal’s main characteristics

Activity

Blasting, extraction, crushing and screening of a maximum of 100,000 cubic metres of rock and clay/silt per annum.

Hydrology The majority of the proposed quarry site drains to the east, directly into a tributary of the Camden Rivulet. A small portion of the north-western area of the site drains westerly into Camden Creek which reports to Camden Rivulet downstream of the dam wall.


4

Fauna The Ecological Assessment, conducted as part of the EER, did not identify any fauna species listed as threatened under the Threatened Species Protection Act 1995 (TSP Act) or the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) within the proposed quarry area.

Flora The Ecological Assessment did not identify any ecological communities listed under the EPBC Act within the proposed quarry area, however, two vegetation communities (Freshwater Aquatic Sedgeland and Rushland (ASF) and Nothofagus – Atherosperma rainforest (RMT)), listed under Schedule 3A of the Nature Conservation Act 2002 (NC Act) were identified within the margins of mining lease 2024P/M.

The natural values database indicates the occurrence of slender curved riceflower, a listed species under Schedule 3 of the TSP Act, within the proposed quarry footprint.

Local region

Climate Rainfall is approximately 1,572mm per annum. Wind direction is predominantly west or north to north-westerly.

Surrounding land zoning, tenure and uses

The surrounding land uses are predominately forestry and agriculture. A permanent timber production zone is located approximately 1km east and the Mt Barrow State Reserve is located 3.4km south-west of the proposed quarry area.

Species of conservation significance

The Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) listed Riverbed wintercress (endangered) is known to occur within the Camden Rivulet downstream of the proposed quarry1

Proposed infrastructure

Major equipment The EER states that the type/model of equipment used will be determined by a contractor prior to commencement, but that nevertheless, extraction will likely involve the use of:

• Bulldozers;

• Excavators;

• Crusher (North Pit only);

• Drilling equipment (North Pit only);

• Screener vibrators (North and South Pits); and

• Haulage trucks.

Other infrastructure

• Sediment retention basin;

• Site drainage (e.g. intercept drains and culverts);

• Access roads; and

• Stockpiles.

Inputs

Water Water may be used for dust suppression.

Energy Diesel fuel will be used for fuelling on-site machinery.

Other raw materials

Explosives will be brought to the proposed quarry as required by the blasting contractor.

1 NB this species is not listed under Schedule 5 of the TSP Act and therefore is not considered in this assessment report.


5

Wastes and emissions

Liquid Stormwater runoff from extraction and stockpile areas.

Atmospheric Dust from internal traffic, stockpiles and from crushing, screening and blasting activities.

Solid Small amounts of general wastes including packaging materials, small amounts of construction wastes and machinery consumables.

Controlled wastes

None.

Noise Mobile equipment such as excavators, dozers, drill rigs and haulage trucks will create noise emissions, as will the blasting, crushing and screening activities.

Greenhouse gases

Mobile equipment (excavators, dozers, vehicles, drill rigs, trucks) will produce greenhouse gas emissions.

Construction, commissioning and operations

Proposal timetable

The Scottsdale Irrigation Scheme (SIS) is due to commence construction in the fourth quarter of 2017 and is estimated to be completed within 18 months. Material extraction will require approximately 6 months to complete during that 18 month period.

Operating hours (ongoing)

The proposed quarry will operate between 0700 hours to 1900 hours Monday to Friday.

4 Need for the proposal and alternatives According to the EER the Camden Rivulet Dam (the Dam) is identified as a key component of Tasmanian Irrigation’s Scottsdale Irrigation Scheme. The purpose of the SIS is to enhance the productivity of the dairy and livestock industry, as well as the potato, poppy and vegetable production industry, within the Scottsdale region. Geotechnical investigations associated with the construction of the Dam have identified that there may be an insufficient volume of suitable construction material (earthen and rock fill) within the Dam footprint to construct the Dam wall. The proponent has therefore proposed the Ben Bullen Quarry as a secondary source of material should additional material be required to construct the Dam wall. The EER states that trucking in required materials from existing external quarry sites was considered as an alternative to the Ben Bullen Quarry. However, this was seen as a potential constraint on the project that would result in the generation of significant offsite haulage traffic and also increase the cost of dam construction considerably. According to the EER, identifying a material source adjacent to the Dam site was deemed the most cost effective and efficient way of mitigating the risk of having an insufficient volume of material within the Dam footprint to complete the construction of the Dam wall. Recent harvesting of plantation from the proposed quarry site was also considered advantageous to disturbing other nearby land, particularly native forest.

5 Public and agency consultation A summary of the government agency/body submissions is contained in Appendix 1 of this report. No public representations were received. The EER was referred to a number of government agencies/bodies with an interest in the proposal. Responses were received from the following:

• Mineral Resources Tasmania; • TasWater; and • Launceston City Council.

The following Divisions/areas of the Department of Primary Industries, Parks, Water and Environment were also consulted on the EER:

• Regulator, EPA Tasmania; • Natural & Cultural Heritage Division.

Section 6 of the EER states that extensive public consultation has been undertaken by the proponent regarding the construction and operation of the SIS over the past seven years. According to the EER, the proponent has regularly consulted with the landowner regarding the acquisition of the Dam site over the past five years. The proponent indicates that the landowner supported the Notice of Intent submitted to EPA Tasmania in regards to the proposed quarry site. The EER also states that the Indigenous community has been consulted, as facilitated by Aboriginal Heritage Tasmania (AHT), in regards to the proposed irrigation scheme. In addition, the EER was forwarded to AHT. They indicated that the proponent has undertaken the required steps with regards to Aboriginal Heritage in accordance with the Aboriginal Relics Act 1975 and considered that no further action was required.

6 Evaluation of environmental issues The environmental issues considered relevant to the proposal have been evaluated by the EPA Division. Details of this evaluation, along with the permit conditions required by the Board, are discussed below. Issue 1: Flora, fauna and habitat Description of potential impacts

The Ecological Assessment, included in Appendix B of the EER found that the majority of the proposed quarry site is located within a recently cleared plantation area with small areas of native forest (predominantly Acacia dealbata) and other exotic vegetation. The Ecological Assessment did identify two small areas on the margin of mining lease 2024P/M (the mining lease) containing threatened flora communities listed under Schedule 3A of the Nature Conservation Act 2002 (NC Act). Freshwater aquatic sedgeland and rushland (ASF) was mapped along the tributary to the Camden Rivulet and Nothofagus – Atherosperma rainforest (RMT) was mapped on the north eastern margin of the mining lease; refer to Figures 4-1 and 4-2 of the EER. Furthermore, advice from the proponent on 23 May 2017 states that the 2015 Ecological Assessment determined that the ASF should be reclassified as highland grassy sedgeland (MGH), also a listed community under the NC Act. It was noted that the natural values database also holds a record of the slender curved riceflower within the north eastern area of the mining lease. According to the EER, native and threatened fauna may pass through and use the proposed site to forage. The EER states that no breeding habitat was identified within the proposed quarry area during the Ecological Assessment. If not managed appropriately, the proposed quarrying activity has the potential to impact on threatened flora and fauna values.

Management measures proposed in EER

Commitment 1 – A site specific Construction & Environmental Management Plan (CEMP) will be prepared and submitted to the EPA prior to construction. Commitment 2 – The remnant patch of Nothofagus – Atherosperma rainforest (RMT) and a small patch of mapped aquatic sedgeland and rushland (ASF) within the project site will be marked out on site as no-go zones and remain undisturbed (unless within the Dam permit area). The EER also states that in addition to the two areas of threatened flora being marked on maps within the CEMP as no-go zones, they will also be taped off to ensure that the no-go zones are physically marked out. Furthermore, the proponent’s Environmental Protection Guideline (EPG 1) – Disturbance to Terrestrial and Aquatic Flora and Fauna (refer to Appendix A of the EER) includes additional mitigation measures, in particular protocols for the unexpected discovery of dens or nests.

Public and agency comment

No public or agency representations were received in relation to flora, fauna and habitat.

Evaluation

The measures to protect threatened flora, as expressed by commitment 2 and marking out of these areas with tape are necessary and supported. Condition FF2 is imposed to ensure that the areas containing threatened flora are physically marked out to help avoid disturbance from


11

machinery or other activities. Further advice from the proponent via email on 23 May 2017 stated that under Dam Works Permit No. 2016009250 a small amount of the MGH is required to be cleared where it is located within the Camden Dam Rivulet inundation area (see Attachment 2 of Permit Conditions – Environmental no. 9480). It was therefore considered appropriate for condition FF2 to exclude the area of MGH required to be cleared under the Dam Works Permit from requiring fencing and protection. While the EER notes that the 2012 Ecological Assessment identified the listed threatened species slender curved riceflower within the north eastern corner of the mining lease, the EER also notes that the 2015 Ecological Assessment did not identify the species and has concluded that the species was most likely misidentified as the non-threatened Pimelea pauciflora. The EER acknowledges that there is potential for the proposed quarry to be used by threatened fauna species for foraging (but not as core habitat) as they move through the area. However, given the disturbed nature of the site, relatively small footprint and short term nature of the activity, impacts to threatened fauna are likely to be negligible; consequently, no further conditions are considered necessary.

Conclusion

The proponent will be required to comply with the following site-specific condition: FF2 Protection of threatened vegetation communities


12

Issue 2: Weed and disease management Description of potential impacts

Gorse, a declared weed under the Tasmanian Weed Management Act 1999 and also a Weed of National Significance has been identified within the broader irrigation scheme area, however, it was not observed within the proposed quarry footprint. Nevertheless, there is potential for plant and equipment to transport weeds and diseases to and from the site and between the proposed quarry and the Camden Rivulet Dam site, if appropriate management measures are not put in place.


Commitment 1 discussed above is considered relevant to weed and disease management. Commitment 3 – A Weed and Hygiene Management Plan will be included as part of the CEMP. The EER states the Weed and Hygiene Management Plan will include, as a minimum, wash down prior to entry and exit from the site in accordance with the Weed and Disease Planning and Hygiene Guidelines – Preventing the spread of weeds and diseases in Tasmania, DPIPWE, 2015 (Weed Guidelines) and weed inspection and control during and post operation in accordance with the Quarry Code of Practice 1999 (QCoP). Tasmanian Irrigation’s Environment Protection Guideline – EPG 4 – Weed and Hygiene Control is also contained in Appendix A of the EER and outlines a framework for managing weeds and diseases at the site.


No public or agency representations were received in relation to weed and disease management.

Evaluation

The proponent’s commitment to developing a Weed and Hygiene Management Plan in accordance with the Weed Guidelines is supported. Condition FF1 requires the proponent to manage weeds in accordance with the Weed Guidelines. The other management measures proposed are considered to be consistent with the Weed Guidelines and are supported. In addition, the proponent has committed to manage weeds in accordance with the QCoP; this is imposed by condition G7 requiring the activity to be undertaken in accordance with the QCoP.

Conclusion

The proponent will be required to comply with the following standard condition: G7 Quarry Code of Practice The proponent will also be required to comply with the following site-specific condition: FF1 Weed Guidelines


13

Issue 3: Stormwater and sediment management Description of potential impacts

The mining lease has a total footprint of 45ha, however, the EER states that the area of disturbance for the north and south pits will be approximately 12ha. The remaining area may potentially be utilised for topsoil stockpiles, screening / crushing equipment and drainage infrastructure, as shown on the indicative site plan (Figure 2 of this report). The proposed quarry is comprised of the north pit (rock and general fill material) and the south pit (clay materials only). The two pits are divided by a small saddle where an ephemeral drainage line runs to the east, intersecting a tributary of the Camden Rivulet. The north pit is located on a small hill that drains predominantly to the east, but also west to Camden Creek, as shown on Figure 2 of this report. The south pit will be excavated into an east facing slope, all drainage from this pit will be towards the tributary on the eastern boundary of the mining lease. The proposed quarry is located within a TasWater drinking water catchment. If appropriate measures are not implemented there is potential for stormwater to inundate the extractive pits causing erosion and the movement of sediment into the unnamed tributary and potentially the Camden Rivulet which may impact on water quality.


Commitment 4 – An Erosion and Sediment Control Plan (ESCP) will be included as part of the CEMP. Commitment 5 – Drainage and sediment control will be installed at the project site prior to operation. Commitment 6 – Water management infrastructure will be inspected weekly during dry weather and daily during wet weather. Commitment 7 – Waterways will be monitored in accordance with the SIS Camden Dam Turbidity Management Framework. The EER states that the ESCP will be developed in accordance with the QCoP, any permit conditions and relevant Australian Standards. The proponent notes that the key mitigation measures outlined in Section 4.2.5 of the EER will be incorporated into the ESCP, including construction of drainage lines and collection of potentially impacted stormwaters in a drainage sump prior to discharge, development of wet weather stop work procedures, minimisation of vegetation removal, returning drainage to pre-quarrying conditions upon cessation of the activity, and regular monitoring.


TasWater noted there is potential for the proposed development to impact on raw water quality in the St Patricks River, and therefore the Distillery Creek Water Treatment Plant. TasWater supported the measures outlined in Section 4.2.5 of the EER relating to the control of erosion and sediments. TasWater also noted the proponent should notify it immediately if an event, such as a fuel spill or failure of sediment control infrastructure, that may pose an imminent risk to drinking water quality occurs. No public or further agency representations were received in relation to stormwater and sediment management.


14

Evaluation

Figure 2 of this report shows indicative locations of cut off drains and the drainage sump. However, it is noted this configuration may be subject to modification once a contractor has been appointed. Due to the high naturalness value of the Camden Rivulet and known occurrence of the EPBC Act listed riverbed wintercress (endangered) downstream of the quarry, the proposed installation of stormwater and sediment control infrastructure and the measures outlined in Appendix A of the EER (including the Turbidity Management Framework) are considered necessary to limit erosion and control sediments. Therefore, the following standard conditions are imposed. The development of a CEMP which contains an Erosion and Sediment Control Plan developed in accordance with the QCoP and any relevant Australian Standards is also supported. Condition E3 requires any polluted stormwater that will be discharged from the land to be collected and treated prior to discharge to the extent necessary to prevent environmental harm or nuisance, which may include sediment settling ponds or retention basins. It also requires that stormwater discharged from the land must not carry pollutants or sediments in such concentrations as to degrade the visual quality of receiving waters outside of The Land. Additionally, condition E1 requires the proponent to construct and maintain perimeter cut-off drains to prevent stormwater from entering the working area or other disturbed areas that have sufficient capacity to handle a 1 in 20-year storm event. Furthermore, condition E2 requires sediment settlement ponds to be constructed and maintained to ensure sufficient capacity to settle sediments out during a 1 in 20-year storm event. Condition DC3 also requires that stockpiles of topsoil must be protected from erosion or other disturbance. Refer to issue 8 for further discussion. In addition, the proponent has committed to manage stormwater and sediments in accordance with the QCoP; this is imposed by condition G7 requiring the activity to be undertaken in accordance with the QCoP. It is considered that the inclusion of the above mentioned conditions to support the proponent’s commitments is sufficient to reduce the potential risk to the environment from stormwater and sediments that may arise as part of the proposed activity. In addition, TasWater was supportive of the proponent’s commitments to minimise risks to the drinking water catchment.

Conclusion

The proponent will be required to comply with the following standard conditions: G7 Quarry Code of Practice E1 Perimeter drains E2 Design and maintenance of settling ponds E3 Stormwater


15

Issue 4: Air emissions Description of potential impacts

The proposed quarry is likely to have a total disturbed footprint of approximately 12ha which is likely to be entirely exposed to wind and rain on completion of extraction. During operation, machinery such as trucks and excavators will be moving on and off the site as well as within the proposed extractive pit area itself which may generate dust. There is also likely to be stockpiled material (topsoil) located within the proposed quarry footprint. Blasting, crushing and screening activities within the north pit may also produce dust emissions. If these activities are not managed appropriately, there is potential for dust emissions to leave The Land which has the potential to cause environmental nuisance.


Commitment 8 – A complaints register to monitor and address any dust, noise or other complaints will be maintained. The EER also states that the CEMP will comply with the QCoP and the construction Environmental Protection Requirements (EPR’s) contained in Appendix A of the EER; and that mitigation measures will include (as a minimum) visual monitoring of dust levels, water spraying if dust becomes an issue, restriction of vehicle speeds, maintaining a complaints register, management of blasts to reduce the amount of dust generated and rehabilitation of exposed areas as soon as practical.


No public or agency representations were received in relation to air emissions.

Evaluation

The nearest land in other ownership is approximately 800m west of the north pit and 940m south of the south pit. The nearest identified sensitive receptors are located approximately 680m south, 1.2km south-west and 1.8km north-east of the proposed quarry area. The proposed management measures for control of dust emissions are considered to be appropriate and are supported given the location and distances to the nearest sensitive receptors. However, there is potential for a large area to be disturbed (12ha) that may produce dust emissions, it is therefore considered appropriate to include condition A1 which requires the proponent to control dust emissions to prevent environmental nuisance beyond the boundary of The Land. Given the separation distances and short term nature of the operation dust related nuisance is considered unlikely, therefore implementation of further dust control measures for the activity are not considered necessary.

Conclusion

The proponent will be required to comply with the following standard condition: A1 Control of dust emissions


16

Issue 5: Solid and liquid waste management Description of potential impacts

Solid wastes will be restricted to general wastes including packaging materials, and small amounts of constructions wastes. Inappropriate collection, storage or disposal of these wastes has the potential to cause environmental nuisance. The EER states that no liquid wastes are expected to be produced at the proposed quarry.


The EER states that waste streams will be collected in on-site covered skip bins and removed from the site on a regular (i.e. weekly) basis. Where possible waste segregation will be applied, with separate vessels for recyclable and non-recyclable materials.


No public or agency representations were received in relation to solid and liquid waste management.

Evaluation

Given the short term nature of the activity and the likely types and low volume of waste generated at the site, the above mentioned management measures are considered appropriate and supported. Specific conditions in regards to waste management are not considered necessary for this proposal. It should be noted, however, that condition G7 is included. This requires that the activity undertaken must comply with the acceptable standards provisions of the QCoP (which includes waste management provisions). In addition, OI1 outlines the appropriate manner in which to manage wastes (i.e. reduce, re-use or recycle wastes where possible).

Conclusion

The proponent will be required to comply with the following standard condition: G7 Quarry Code of Practice The following information is included in the permit: OI1 Waste management hierarchy


17

Issue 6: Noise emissions Description of potential impacts

According to the EER noise will be generated by machinery (trucks, excavators, dozers and light vehicles), equipment (crushing, screener vibrators and blast hole drilling equipment) and blasting. If not managed appropriately there is potential for nuisance noise and vibration emissions to occur.


Commitment 8 discussed at issue 4 of this report is considered relevant to noise emissions. Commitment 9 – Operation of machinery and equipment will be restricted to daytime hours (0700 hrs to 1900 hrs) Monday to Friday. Commitment 10 – The contractor will prepare a Blast Management Plan addressing noise and vibration, prior to blasting. Commitment 11 – The contractor will notify nearby residents 24 hours prior to blasting. Commitment 12 – Blasting will occur during daylight hours only (between 1000 hrs and 1600 hrs). In addition to the above commitment, the EER states the CEMP will contain additional noise mitigation measures including, selection and maintenance of quality equipment fitted with industry standard noise reduction mechanisms, employing a licenced blasting contractor to undertake blasting in accordance with the QCoP and keeping blasts (if required) small to minimise the potential for nuisance noise and vibration emissions.


No public or agency representations were received in relation to noise emissions.

Evaluation

While the specific type and model of machinery that will be used is unknown, it is not anticipated that the machinery likely to be used would generate a significant or unacceptable noise impact on the nearest sensitive receptors, noting that blasting and crushing will only occur in the north pit. The proposed quarry is located approximately 680m south, 1.2km south-west and 1.8km north-east of the nearest sensitive receptors. In addition, the proposed quarry will only be operated for a short term and during daytime only. Haulage trucks will only travel on internal roads (which do not form part of this assessment, since they are outside of the proposed quarry area). The proposed hours of operation are consistent with those in the QCoP and are appropriate to help limit noise impacts. While blasts will produce ground vibration and noise emissions, impacts on the nearest sensitive receptors are considered unlikely, due to the small and infrequent nature of the blasts and the separation distances to the sensitive receptors. Nevertheless, it is considered appropriate to impose condition B1 to ensure that blasting is undertaken only during daytime hours on weekdays. It is also considered appropriate to include condition B2 to ensure that if noise and vibration issues arose, the Director could require the proponent to demonstrate the noise and vibration limits are being met at any residence or other noise sensitive premises. Condition G7 also requires that the activity must comply with the acceptable standards provisions of the QCoP and supports the proponent’s commitments. The proposed management measures and hours of operation and the requirement to operate


18

the quarry in accordance with the QCoP are adequate to manage the potential noise and vibration emission risks to the nearest sensitive receptors. Further noise emission conditions are not considered necessary.

Conclusion

The proponent will be required to comply with the following standard condition: G7 Quarry Code of Practice B1 Blasting times B2 Blasting – noise and vibration limits


19

Issue 7: Dangerous goods and environmentally hazardous materials Description of potential impacts

The EER states quarrying machinery will remain in-situ during the proposed quarrying works and require refuelling and minor servicing on-site by mobile fuel trucks / mechanics. The minor servicing works may include the use of small volumes of hydraulic fluid. The blasting contractor will transport explosives onto the site as required for each blast. Should fuel or hydraulic fluid be handled incorrectly or a spill to the environment occur there is potential for contamination of soil, groundwater and waterways that could cause environmental harm or nuisance. As noted, the proposed quarry lies within a drinking water catchment.


Commitment 13 – Hydrocarbon spill kits will be present for all refuelling/servicing events in-situ. The EER states that wherever possible mobile equipment (e.g. trucks) will be refuelled off-site at the Dam construction site and that any major servicing works will also be undertaken at the Dam construction site where a suitable servicing area will be provided. The EER also states that no dangerous goods or environmentally hazardous materials will be stored on-site. In addition to the above management measures, the EER states that the CEMP will contain additional mitigation measures including, training of staff in the use of the spill kits, any refuelling trucks will also contain a spill kit, in the event of a spill it will be contained and impacted soils will be excavated and removed for disposal by a licenced contractor, and that any refuelling / servicing activities undertaken on-site will be undertaken well away from any waterways.


No public or agency representations were received in relation to dangerous goods and environmentally hazardous materials.

Evaluation

The management measures proposed above are considered to be appropriate for the relatively minor volumes of dangerous goods to be transported onto the site, noting that no storage of dangerous goods will occur on-site. To support the proponent’s commitments condition H1 is included which requires that appropriate spill kit(s) are located on-site to contain any spills that may occur. Additionally, condition H2 requires that where fuelling or servicing of mobile or fixed plant on The Land is required, all reasonable measures must be implemented to prevent unauthorised discharge, emission or deposition of pollutants. The QCoP also has general acceptable standards for the storage of hazardous materials, therefore permit condition G7 is also relevant.

Issue 8: Decommissioning and rehabilitation Description of potential impacts

According to EER, the short term nature (6 months) of the proposed quarry, means progressive rehabilitation is not likely to be feasible. It is therefore likely that the entire proposed extractive pit area will be disturbed (12ha) before any rehabilitation occurs. Therefore, the potential for dust and erosion impacts is heightened due to the large area being disturbed. Additionally, should the rehabilitation not be conducted appropriately and in a timely manner after completion of extraction, those risks are likely to further increase.


Commitment 15 – A detailed Rehabilitation Plan will be submitted to the EPA by the contractor at least 30 days prior to commencement of construction of the project. Section 4.15 of the EER outlines some basic rehabilitation principles that will be followed, including rehabilitation to pre-quarrying condition suitable for forestry use, removing all infrastructure, reuse of stockpiled topsoil, use of appropriate seed mixes where required, ensuring natural drainage is reinstated to prevent erosion, removal of roads and monitoring of rehabilitation efforts.


No public or agency representations were received in relation to decommissioning and rehabilitation.

Evaluation

While it is standard practice to require progressive rehabilitation for a typical quarry, the purpose and nature (i.e. only 6 months of operation) of the proposed quarry is not conducive to progressive rehabilitation. The total area exposed upon completion of extraction is likely to be up to 12ha, therefore the proponent will need to pay close attention to how dust, erosion and sediment control is managed. The proponent’s commitment to stockpile topsoil for reuse during rehabilitation works of the proposed quarry is imposed by condition DC3. There is potential for dust and sediments to be mobilised from these stockpiles if not appropriately managed. Issues 3 & 4 above, outline proposed management measures / commitments in relation to stockpiles. Those measures are consistent with condition DC3. It is considered that the short operational timeframe, relatively simple nature of the extraction and proposed end use (suitable for forestry) will require modest rehabilitation effort. Nevertheless, given the area of land exposed with no progressive rehabilitation being undertaken, it is considered appropriate to include conditions DC4 and DC5 to require the proponent to develop and implement a Decommissioning and Rehabilitation Plan (DRP). The rehabilitation principles detailed in Section 4.15 of the EER are generally supported and should inform the final DRP that is to be submitted to the Director for approval within 3 months of the date operations commence, as required to be reported to the Director by condition G6.

Additionally, standard conditions require the proponent to notify the Director, EPA of the permanent cessation of the activity (DC1), or where a temporary suspension of the activity is likely to occur (DC2).

Conclusion

The proponent will be required to comply with the following standard conditions: G6 Notification prior to commencement


21

G7 Quarry Code of Practice DC1 Notification of cessation DC2 Temporary suspension of activity DC3 Stockpiling of surface soil DC4 Rehabilitation following cessation The proponent will also be required to comply with the following site-specific conditions: FF1 Weed Guidelines DC5 Decommissioning and Rehabilitation Plan

following requirements:1.1 ponds must be designed to successfully mitigate reasonably foreseeable sediment

loss which would result from a 1 in 20 year storm event;1.2 discharge from ponds must occur via a stable spillway that is not subject to

erosion;1.3 all pond walls must be stable and treated with topsoil and vegetated or otherwise

treated in such a manner as to prevent erosion; and1.4 sediment settling ponds must be periodically cleaned out to ensure that the pond

design capacity is maintained. Sediment removed during this cleaning must besecurely deposited such that sediment will not be transported off The Land bysurface run-off.

E3 Stormwater1 Polluted stormwater that will be discharged from The Land must be collected and

treated prior to discharge to the extent necessary to prevent serious or materialenvironmental harm, or environmental nuisance.

2 Notwithstanding the above, all stormwater that is discharged from The Land must notcarry pollutants such as sediment, oil and grease in quantities or concentrations that arelikely to degrade the visual quality of any receiving waters outside the Land.
