1.0 Introduction Lynwood Quarry is owned and managed by Holcim (Australia) Pty Ltd (Holcim). The quarry is located in the Goulburn Mulwaree Local Government Area, approximately 160 kilometres southwest of Sydney and approximately 27 kilometres north-east of Goulburn (refer to Figure 1.1). Construction of the project commenced in November 2010, with operations anticipated to commence in 2014. Holcim (formerly Readymix) was granted development consent on 21 December 2005 (DA-128-5-2005) by the Minister for Planning for the construction and operation of Lynwood Quarry. Minor modifications to the development consent were approved in May 2009, March 2011 and August 2011, the modifications are further discussed in Section 1.2.1. Lynwood Quarry will provide a long-term supply of high quality construction material into the Sydney, regional and local markets. This Annual Review details the operational and environmental management activities of Lynwood Quarry during the period 1 July 2011 to 30 June 2012. The report has been prepared in accordance with Condition 6 of Schedule 5 of the Development Consent. 1.1 Overview of the Project

The Lynwood Quarry site is bounded to the south by the Hume Highway and bisected in an east-west direction by the Main Southern Railway. It incorporates the headwaters of Joarimin, Lockyersleigh and Marulan Creeks and has historically been used primarily for agriculture, in particular grazing. Lynwood Quarry will provide a long-term supply of high quality construction material into the Sydney, regional and local markets. The supply to the Sydney market will replace supply from existing quarries that are nearing the end of their resources. The project area contains a substantial, high quality, hard rock resource with ready transport access to the Main Southern Railway and Hume Highway. The quarry is approved to produce up to five million tonnes per annum (Mtpa) of saleable quarry product for an initial 30 year quarrying period (refer to Figure 1.2). The target resource has an expected life of in excess of 90 years. 1.2 Consents and Licences

The operation of Lynwood Quarry is regulated by a range of licences and approvals from both state and local authorities. For environmental purposes, these include: • Development Consent (DA 128-5-2005), as modified;

• Environment Protection Licence (EPL) No. 12939;

• A Controlled Activity Approval (CAA No. 10 ERM 2011/0446) under the Water Management Act

2000 (WMA Act) for works within the Joarimin Creek, Lockyersleigh Creek and Marulan Creek riparian zones. The Controlled Activity Approval was modified on 4 May 2012 to include a temporary creek crossing ‘J13’ which was required in order to construct the rail turn out;

• Aboriginal Heritage Impact Permit (AHIP) No. 1100264 which consolidates previous AHIPS for the

site and covers ongoing works to be undertaken at Lynwood Quarry; and

• S65 Approval under the Heritage Act 1977 (2009/S65A/13).


1.2.1 Development Consent

Development consent (DA-128-5-2005) for Lynwood Quarry’s operation and surface facilities was granted on 21 December 2005 by the Minister for Planning. In May 2005, Holcim lodged a development application and accompanying Environmental Impact Statement (EIS) (Umwelt, 2005) with the then Department of Infrastructure, Planning and Natural Resources (DIPNR) (now Department of Planning and Infrastructure (DP&I)) for determination by the then Minister for Infrastructure and Planning. The project was classed as a State Significant Development under Section 76 A(7) of the EP&A Act. Development Consent was granted for the project on 21 December 2005. On 7 May 2009, Holcim received approval to modify the design of the Quarry (Modification 1) in accordance with Section 96(1A) of the EP&A Act. A Statement of Environmental Effects (SEE) was prepared by Umwelt (Umwelt, 2009) on behalf of Holcim to assess the potential environmental impacts of the proposed modifications, which comprised:

• the quarry footprint being reduced in the western extent, which necessitated changes in the

progression of the quarry pit, due to the identification of a fault in this area;

• a revised layout of Quarry site infrastructure including the crushing and screening plant;

• a revised conceptual design of the Hume Highway interchange; and

• approval for delivery of quarry product by road to all markets, due to the potential for staged construction.

On 22 March 2011, approval for Modification 2 to the development consent was granted by the then Department of Planning (now DP&I) to optimise the site infrastructure and site layout. The key modifications included reconfiguration of the rail loop to a rail spur, relocation of the office facilities and other infrastructure components, minor changes to the quarry pit development and crushing equipment and minor changes to the western excess product emplacement area. On 19 August 2011, a minor modification to the Development Consent for Lynwood Quarry (128-5-2005) was approved (MOD 3). The modification related to: • modification of the date in the consent relating to the submission of the first Annual Review to

reflect the date of commencement of construction; and

• modification of the date of the commissioning of first the Independent Environmental Audit to reflect the date of commencement of construction of the project in November 2010.

This Annual Review has been developed in accordance with Condition 6 of Schedule 5 of the Development Consent. Table 1.1 details the consent condition and where the requirements are addressed in this document.

1.4 Employee Training During the reporting period Holcim, in conjunction with the primary civil contractor BMD Constructions (BMD), developed a comprehensive environmental training program for all employees, contractors and visitors at Lynwood Quarry. The training package was designed to ensure that personnel gain a sound understanding of relevant environmental issues and management strategies, environmental incident and emergency response procedures, and their role and responsibilities in developing, implementing the requirements of the Environmental Management Strategy. The training program consists of: • Holcim Australia Environmental induction – this is Holcim’s national environmental induction and

covers a range of environmental issues including dust, noise, water, vegetation and traffic;

• Site specific Lynwood Quarry induction – this induction is completed by all personnel entering the site and includes comprehensive information on Aboriginal heritage,

• Environmental awareness training – this competency based training is part of the site induction process to ensure that all personnel have knowledge of the relevant roles and responsibilities that relate to their activities;

• Emergency response training – this covers general safety aspects and also environmental specific issues such as bushfires; and

• Regular toolbox talks – these talks address specific environmental issues, such as findings from incident or complaint investigations, or improvement initiatives.


2.0 Summary of Operations during the Report Period

2.1 Construction

In the 2012 Annual Reporting period the civil earthworks progressed to approximately 90% completion. BMD were the primary contractor for the civil works, including the Hume Highway interchange which was constructed under Roads and Maritime Services (RMS) authority. A summary of construction works for the period is provided below:

Completion of Sedimentation Dams A and E, and Supply Dam 1; Installation of water pipeline infrastructure, linking Sedimentation Dams A, E and F to Supply

Dam 1; Completion of earthworks for the ‘South Pad’ – the area to the south of the Main Southern

Rail where the future processing plant will be located; Completion of blasting and earthworks to create the foundation for the primary crusher; Rail siding construction and commencement of rail turnout, linking the siding to the Main

Southern Rail; 80% completion of the main site access road, from the Hume Highway interchange to the

future quarry infrastructure area; Commencement of topsoiling and revegetation of access road batters and table drains 75% completion of the Hume Highway Interchange; and 80% completion of electrical infrastructure including installation of high voltage and low

voltage conduits, transformers and the switch room.

2.2 Quarrying Activities

The foundation for the Primary Crusher was constructed during the reporting period. This was undertaken as part of the civil works contract and involved drilling, blasting and earthworks to construct the face where the Primary Crusher will be located in the future. The excavation, drilling and blasting produced approximately 200kt to 300kt of Primary Raw Feed which has been stockpiled for use in the infrastructure commissioning phase.

3.0 Environmental Management, Monitoring and Performance

A range of environmental monitoring was undertaken during the reporting period. All environmental monitoring locations are shown on Figure 3.1. The locations are representative of EPL requirements for Lynwood Quarry. There are presently differences with the monitoring locations specified in the EPL (currently the monitoring locations in place) and those outlined in the approved Environmental Monitoring Program prepared in accordance with Condition 3 of Schedule 5 of the development consent (intended long-term monitoring locations). It is noted that DP&I advised in a letter dated 4 April, 2012 that Holcim have the monitoring locations amended to reflect the Environmental Monitoring Plan by the 2011/12 reporting period. This was not completed; however Holcim has a program in place for the 2012/13 reporting period to rectify this situation. A brief summary of environmental management techniques applied during the reporting period are also provided in the sections below. Environmental impact predictions from the initial site EIS and the modifications SEE and EA were based on the site operating at full capacity, thus impacts from site earthworks and construction activities during the reporting period are, in most cases, significantly less than the impacts expected at full operating capacity as assessed through the environmental assessment and planning process. As detailed in the following sections, there have been some issues with the implementation of some aspects of the environmental monitoring program at Lynwood Quarry over the reporting period. In particular, there have been issues with the implementation of the noise monitoring program with only two quarters being monitored in the reporting period. Holcim has identified improvement opportunities for the noise monitoring and has taken steps to engage a specialist noise monitoring consultant for all future noise monitoring works. 3.1 Review of Management Plans and Monitoring Programs

During the annual reporting period the Lynwood Quarry Environmental Management Plans were revised to reflect the 2011 Modification 2 of the Consent. On 4 April, 2012 Department of Planning advised Holcim that the following management plans had been approved: Environmental Management Strategy; Environmental Monitoring Program; Noise Monitoring Program; Blast Monitoring Program; Air Quality Monitoring Program; Construction Traffic Management Plan; and Caring for Country Aboriginal Heritage Management Plan.

The following documents were approved in principal, providing that minor amendments to the plans would be made in accordance with Department of Planning requirements: Water Management Plan; and Rehabilitation and Landscape Management Plan.


Given that the Independent Environmental Audit took place during the reporting period and this triggers a review of Management Plans, the required amendments to the above plans will be incorporated into the management plan reviews, to be submitted to DP&I in January 2013. 3.2 Meteorological Monitoring

A meteorological station is located at Lynwood Quarry as shown in Figure 3.1. This meteorological station location is representative of the meteorological conditions experienced at Lynwood Quarry. During the reporting period in early 2012, it was discovered that the Lynwood Quarry Meteorological Station data had been corrupted. Technicians speculated that this was likely caused by a lightning strike to the station. Despite attempts to retrieve the data, the monitoring results for the reporting period could not be salvaged. In light of this, for the purposes of the reporting period, the meteorological data from the closest Bureau of Meteorology (BoM) weather station has been used – Goulburn Airport, Station No.: 070263. The Lynwood Quarry meteorological station will be repaired during the next reporting period. 3.2.1 Rainfall

For the purpose of this report, rainfall data has been sourced from the records Bureau of Meteorology station 070263.

TOTAL 799 190 As shown in Table 3.1, annual rainfall for the reporting period was 799mm, which is higher than the annual average of 607 mm identified in the Lynwood Quarry EIS (Umwelt, 2005). Rainfall was particularly high during February and March, with a total of almost 350mm of rain falling in this period. The local Goulburn-Mulwaree region experienced significant flooding during this period.


3.2.2 Wind For the purpose of this report, wind rose data has been sourced from the records of BoM station 070263. The results are presented in Appendix 1 as annual wind roses showing the relative proportions of wind velocities from each compass sector for both 9.00am and 3.00pm. Wind direction was predominantly from the west and to a lesser extent the north west during the months of May through to October. Wind speed during this period was also high, particularly during August, September and November with a high proportion of winds over 40km/hr. In the warmer months of the year (i.e. December through to April, the wind direction was more variable, although still predominantly westerly). 3.3 Air Quality

3.3.1 Dust Management Controls

The dust management controls implemented for Lynwood Quarry during earthworks and construction activities included: • use of water sprays on construction access roads;

• confining traffic to identified construction traffic routes;

• keeping exposed areas to a minimum;

• prompt reseeding of areas no longer required for operational use;

• daily assessment of meteorological conditions to identify wind conditions that may be conducive to excessive dust generation – for example, very high winds, so that proactive measures can be taken to modify construction activities to reduce dust impacts; and

• stop works issued during periods of high winds.

Monitoring undertaken during the reporting period has indicated that construction activities at the site are having minimal impact on background dust levels in the region and are primarily within the criteria for the site, as outlined in Sections 3.2.2 and 3.2.3. 3.3.2 Dust Deposition Monitoring

Condition P1.1 of the EPL identifies dust deposition monitoring requirements for Lynwood Quarry at Points 1 to 8 (Depositional Dust Gauges (DG) 1 to 8) for the purposes of monitoring air quality. The location of each of these points is shown on Figure 3.1. The locations of the DGs and the HVAS’s are consistent with the locations in the EPL and the EIS completed for the site. These locations are however inconsistent with the approved Air Quality Monitoring Program. The DG and HVAS locations will be modified during the 2012 - 2013 reporting period to be consistent with the Air Quality Monitoring Program. The Lynwood Quarry EPL will also be varied to reflect the revised monitoring locations.


DG6 was removed from the revised Air Quality Monitoring Program as approved by the DP&I in April 2012. The results at this location within the site boundary were not deemed representative of air quality conditions at any surrounding privately owned residences or property. Dust deposition monitoring is continuous, with samples being obtained monthly. For each dust gauge location, Insoluble Solids must be reported to EPA in accordance with EPL and Development Consent conditions. Depositional dust results obtained during the report period are detailed within Table 3.2 on the following page. The dust gauge results provided in Table 3.2 include an annual average of the monthly DG results. All dust deposition monitoring locations complied with the 4g/m2/month criteria except for DG3, with an annual average of 6.8 g/m2/month. The samples at DG3 contained bird droppings and/or insects on several occasions which may have increased the insoluble solid content. Also, this DG is located near an external road used by heavy vehicles which potentially impacts the air quality at this location. Baseline data showed elevated results at this location.

All HVAS PM10 data is within the 24 hour criteria limit of 50 µg/m3 and the annual average criteria limit of 30 µg/m3. The annual average for HVAS Site 1 was 7.8 µg/m3; the highest PM10 value recorded for the monitoring period was 20.5 µg/m3. The annual average for HVAS Site 2 was 4.0 µg/m3; the highest PM10 value recorded for the monitoring period was 11.8 µg/m3. As discussed in the previous section, the HVAS locations will be modified during the 2012 - 2013 reporting period to be consistent with the Air Quality Monitoring Program. The Lynwood Quarry EPL will also be varied to reflect the revised monitoring locations. 3.4 Erosion and Sediment Control

During the report period, the construction of permanent sedimentation dams was completed, and ongoing maintenance of construction erosion and sediment controls was undertaken on a regular basis. The Lynwood Quarry Environmental Coordinator undertook regular inspections of disturbed areas, drainage lines and existing environmental controls to identify erosion and sedimentation issues, with management works implemented as appropriate. The construction contractor also undertook daily and weekly inspections of the erosion and sediment controls at the site.


The erosion and sediment control structures were implemented to minimise the potential for increased sediment load migrating into local water courses during the construction phase of works at Lynwood Quarry and to meet the overall site goal of having a neutral or beneficial effect on water quality. Erosion and Sediment Control works have been undertaken within the disturbed areas identified in Figure 2.1. Examples of erosion and sediment controls implemented at the site include: construction of main sedimentation dams (A, E and F) and smaller sedimentation basins; installation of sedimentation fencing, sand bags and straw bales along drainage lines and

suitable use of rock check dams and grass filter strips where appropriate ; prompt seeding of topsoil stockpiles; reseeding and revegetation of exposed areas not required for future operational or construction

purposes as soon as practicable, including topsoiling and seeding of access road batters and table drains; and

inspection of the site following rain events to ensure adequacy of erosion and sediment controls.

Further details regarding erosion and sediment controls implemented at the site are provided in the Water Management Plan for Lynwood Quarry. 3.5 Water Management

The primary objectives of the Lynwood Quarry water management system are: to minimise off site impacts; to ensure neutral or beneficial impact on water systems, with the site forming part of the Sydney

drinking water catchment; to comply with development consent conditions; to comply with Environment Protection Licence (EPL) conditions; and to maximise water use efficiency. 3.5.1 Surface Water Management Surface water management on the site involves the following: installation and regular maintenance of erosion and sediment controls including sediment

fences, straw bales, sandbags and sediment basins; delineation of areas required to be disturbed, ensuring that disturbance is limited to those areas

required and the minimisation of vegetation disturbance; Appropriate and prompt rehabilitation of disturbed areas no longer required for ongoing

construction or operational purposes; Active management of sediment dam levels via water transfers between dams and drawing

water for use as dust suppression on unsealed surfaces, or irrigation of revegetated areas.

Each of the overburden emplacement areas will be serviced by a sediment dam when construction is completed. Catchment areas, required storage volumes and design criteria for each of these dams are listed in Table 3.4

Notes to Table 3.4: * In accordance with Blue Book Volume 1 and Volume 2E (Landcom, 2004 & DECC, 2008) requirements Construction of site sedimentation dams A, E and F were completed during the reporting period (refer to Figure 2.1). Construction on Water Supply Dam 1 was also completed during the reporting period. A series of pipelines connecting the sedimentation dams to the supply dam are in the process of being installed. These pipelines will allow transfer of water from sediment basins to the supply dams for future processing water.

Sedimentation Dam A


During the reporting period, Sedimentation Dam F overflowed following the significant rainfall event that saw almost 350mm of rain fall in the months of February and March. In the days leading up to the overflow, site activities at the Lynwood Quarry were significantly disrupted due to wet conditions which culminated in the site being shut down for four days due to safety concerns. EPA issued Holcim with a Notice to provide information regarding the overflow in April. Holcim responded to this Notice in June 2012, and in October 2012 EPA advised that no further regulatory action would be taken. Following the overflow a number of measures have been implemented on site to manage water levels in dams, including: Water transfers between sedimentation and supply dams via pumping; Targeting the dam with highest water level for water cart refilling (for dust suppression and

irrigation activities); Maintaining dam levels at a freeboard of at least 0.5m; and Approval to use flocculent on site has been granted by the EPA to improve water quality.

3.5.2 Water Supply and Demand

Water for site amenities is sourced from rainwater tanks installed in the site compound area. During the reporting period no water had to be sourced from off site due to higher than average rainfall. Potable (drinking) water was provided for site staff using water coolers in the site offices. These are delivered approximately every three weeks. The potable water requirements for the site were calculated during the EIS at 1 ML/year during the initial years of the project, increasing up to approximately 2.25 ML/year at full production. 3.5.3 Site Water Balance

The Water Management Plan for Lynwood Quarry states that the ‘water balance will be reviewed once a year as part of the AEMR for the site’. However, as only the civil phase of construction works have been undertaken and the construction of surface water control structures were not completed until late in the reporting period, it was considered unnecessary to complete a full review of the water balance at this early phase of construction. Reporting of the site water balance will be undertaken in future reporting periods, during the operational phase of works to document water supply and demands. 3.5.4 Water Monitoring Program

3.5.4.1 Review of Surface Water Quality

Surface water quality is monitored at four locations on Joarimin Creek (SW3 to SW6) and two locations on Marulan Creek (SW1 and SW2) (refer to Figure 3.1). Other surface water monitoring locations shown on Figure 3.1, SW7 to SW13, are only required to be monitored during periods of active discharge from site sedimentation dams. Surface water sampling was undertaken at six monthly intervals prior to the commencement of construction activities at Lynwood Quarry, however since construction commenced in November 2010 the frequency has increased to monthly. Surface water monitoring results are summarised in Tables 3.5 to 3.10.

Baseline Criteria 1197 7.1 50 10 0.06 1 NS - Not sampled due to no flow in creek on the date of sampling


Surface water results have been compared against trigger values in the Surface Water Monitoring Program and ANZECC Guidelines criteria. A number of samples were not collected due to minimal or nil flow conditions in Marulan and Joarimin Creeks during the reporting period In general, the monitoring results were within the expected values identified from the analysis of baseline data for the site however, during the period of significant rainfall in February to April there were some elevated results, in particular suspended solids at some locations. The pH levels across all sample locations are typically within the ANZECC criteria values of 6.5 to 7.5, with the exception of some occasions when SW1 and SW4 were slightly below these values. These results are within the expected range through analysis of baseline data and are not considered to be non-compliant results. Electrical Conductivity (EC) at the site is variable across sampling locations and appears to be influenced by low flow conditions in the creeks. The general trend across all monitoring locations was a significant reduction in EC following the large rain event. In the period leading up to this rainfall event in early 2012, the dry conditions potentially caused a build up of salts within the creek beds, which would account for the higher levels. In contrast to all other monitoring locations, EC at SW6 peaked around April when all other locations were at their lowest. SW6 is located off site, downstream of SW5 which did not have an elevated EC. It is possible that there was impact external to site operations that impacted this location. For the first six months of the reporting period, suspended solids results were within baseline and ANZECC criteria limits, with the exception of SW3. The elevated suspended solids levels at SW3 were potentially caused by the high level of vehicle activity in the vicinity of this location and the low flows of the creek. In the second half of the reporting period suspended solids significantly increased at several locations, coinciding with the significant rainfall experienced on site. It is likely that the high volume of rainfall caused the suspended solids to increase due to a ‘flushing’ effect of creek beds being inundated. It is also likely that the intensity of the rainfall caused higher than normal erosion in the overall catchment. Suspended solids levels were back to the baseline range by May when weather conditions had stabilised. Total oil and grease results are well within criteria and often below detection limit – all samples for the reporting period were <1mg/L. There appears to be no distinct trend across all samples in Nitrogen and Phosphorous results for the reporting period. Nitrogen and Phosphorous results appear to be slightly increased during the significant rainfall period, particularly SW3. In all cases, the Nitrogen and Phosphorus levels are higher at the monitoring locations within the site than they are downstream. 3.6 Groundwater

3.6.1 Groundwater Monitoring Program A groundwater monitoring program was established in the Lynwood Quarry project area in 2004 to provide baseline groundwater data, with a network of 11 piezometers installed (refer to Figure 2.1). The piezometers were tested quarterly for standing water level during the reporting period, while water quality parameters were tested in July 2010, January 2011 and April 2011. The groundwater monitoring program requires standing water level to be measured quarterly, while groundwater quality analysis is required to be undertaken every 6 months.


As a result of modifications to the development consent during 2011, the Groundwater Monitoring Program was updated in 2011, and approved by DP&I in April 2012. The groundwater monitoring will be updated to reflect the new plan in the 2012/13 reporting period. Results of groundwater monitoring during 2011/12 are provided in Appendix 2. 3.6.2 Groundwater Levels and Flows Groundwater levels have been monitored in all piezometers on a generally monthly basis since July 2004. Groundwater levels during the Annual Review reporting period were monitored quarterly. The monitoring data has been found to have some anomalies in the data set for bores MP-5, MP-9 and MP-11 which are believed to be a result of monitoring practice. Lynwood Quarry has commenced a process of reviewing the monitoring practice for these bores. The groundwater contours are generally in line with the topography, with the highest water table elevations being recorded in the elevated regions near the northern and southern boundaries of the project area, and the lowest in the central zone close to Joarimin Creek. Groundwater flows southwards or northwards towards Joarimin Creek, then flows eastwards in the same general direction as surface flow. Groundwater level data collected during the reporting period is considered to be baseline data, as no earthworks activities intercepted groundwater during the reporting period. 3.6.3 Groundwater Quality Five different water quality aspects of groundwater have been monitored: electrical conductivity;

pH;

trace elements;

nutrients; and

total petroleum hydrocarbons.

Groundwater quality for the reporting period is detailed in Appendix 2. As no earthworks activities intercepted the groundwater table during the reporting period, the groundwater quality information presented in Appendix 2 is considered to be baseline information. 3.7 Blasting

As part of BMD’s construction program, a series of blasts were carried out from December 2011 to May 2012. BMD contracted Orica to undertake these works which consisted of 20 blasts in total. Prior to undertaking any blasting at the site, the following was implemented, in accordance with DA 128-5-2005: Landowners / occupiers within 2 kilometres of the quarry pit were notified about the blasting

schedule on site; and


The Lynwood Quarry blasting hotline was in place to enable the public to get up-to-date information on blasting operations at the development.

BMD made the assessment that the risk of causing ground disturbance due to vehicle bogging outweighed the risk of not monitoring the blasts, and supported this decision by noting that previous peak particle velocity results at this location were well below the 100mm/sec limit. In addition to the gas pipeline not being monitored on several occasions, there was also insufficient blast monitoring information provided for 2 blasts: On 24/01/2012 at the nearest resident (monitoring location B3) the monitoring results were

provided in the form of a “no trigger” statement from Orica, however the statement failed to identify what the trigger level had been set at; and

On 22/02/2012 at the rail underpass, the monitoring results were again provided in the form of a “no trigger” statement from Orica, however the statement failed to identify what the trigger level had been set at.

Excluding the issues outlined above, all monitored blasts undertaken during the reporting period were within the limits specified in the Consent and EPL.


3.8 Operational Noise

3.8.1 Noise Monitoring

Noise monitoring was only undertaken for two quarters during the reporting period, however a program has been put in place to ensure all noise monitoring in undertaken in the following reporting period and thereafter. The monitoring results for the unattended noise monitoring program indicate potential exceedances of the noise affected construction noise criteria for noise monitoring locations N1 to N4. However, it is likely that the Main Southern Railway has some acoustic influence on the noise statistics measured at N1 due to its proximity to the noise monitoring location. Location N3 is potentially affected by noise from the Hume Highway (N3). Locations N1 and N3 are located further from the site than locations N2 and N4. Sites N1 to N4 do not exceed the highly affected noise criteria at any time during the noise monitoring event. As no there were no construction related noise complaints during the time of unattended noise monitoring it is not known if the Project was the cause of the elevated noise levels experienced at the noise monitoring locations. Holcim has committed to implementing best practice work practices outlined in the Interim Construction Noise Guideline (DECCW 2009).Please refer to Appendix 3 for Noise Monitoring Report prepared by Umwelt. 3.9 Visual

Views of the quarry are largely restricted by surrounding topography and vegetation, except for views of the eastern emplacement areas from rural residences to the northeast and filtered views of the quarry and associated works from one residence to the south. The eastern emplacement areas will be constructed during the early years of the project and once established will provide visual screening of the remainder of the project area. Once rehabilitation of these areas is complete, the newly vegetated areas will blend in with the surrounding vegetated topography and will not be significantly visually different. Views of the quarry from major transport corridors will be limited to views from the Main Southern Railway, with these views of short duration, and very limited, distant views from the Hume Highway (as well as views of the new interchange intersection). Potential impacts on night-time scenic quality are not considered to be significant due to the proposed lighting controls and existing light impacted night-time visual character. Selected construction works for the Hume Highway interchange have been undertaken outside of the specified construction hours in accordance with DA 128-5-2005, with written approval from the NSW Roads and Traffic Authority. These works have been undertaken during night-time hours to limit impacts on traffic flow. Therefore there is limited potential for lighting impacts from current activities. Liaison with residents near the relevant work areas was undertaken to address their concerns regarding the hours of construction.


3.10 Threatened Flora

During the reporting period two threatened flora species / communities were identified on site: Hoary Sunray Leucochrysum Albicans var. Tricolor (Hoary Sunray); and White Box, Yellow Box, Blakely’s Red Gum Grassy Woodland and Derived Native Grassland

Critically Endangered Ecological Community (Box Gum Woodland CEEC). Holcim subsequently lodged a referral with the Department of Sustainability, Environment, Water, Populations and Communities in September 2012 under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). 3.10.1 Hoary Sunray The Hoary Sunray is listed as an endangered species under the EPBC Act. Following its identification within the project area including the Hume Highway interchange, works with the potential to impact the species were ceased and Holcim commissioned Umwelt (Australia) Pty Limited (Umwelt) to undertake an inspection and assessment. 3.10.2 Box Gum Woodland CEEC At the time of the original Ecological Assessment (Umwelt 2005), the Box Gum Woodland CEEC was not listed under the EPBC Act. The Box Gum Woodland CEEC was listed under the EPBC Act during May 2006. After a field survey and subsequent analysis, Box Gum Woodland CEEC was identified as being present within the Project Area. 3.11 Threatened Fauna

Five threatened fauna species were recorded during surveys in the Lynwood Quarry project area for the EIS (Umwelt, 2005). The species recorded were the squirrel glider, speckled warbler, eastern bent-wing bat, eastern freetail bat and eastern false pipistrelle. The EIS concluded that the impact of the project on these species in accordance with Section 5A of the EP&A Act would not be significant. One threatened fauna species, the brown treecreeper (listed as vulnerable under the Threatened Species Conservation Act 1995), was recorded within the project area during field surveys for the Environmental Assessment (Umwelt, 2010). No endangered fauna populations were recorded or are expected to occur within the Lynwood Quarry project area. Additional Annual Review reporting requirements are identified in the Rehabilitation and Landscape Management Plan (RLMP) for the site. The following reporting requirements have not yet been triggered but will be triggered prior to the commencement of quarrying operations and reported in future annual reviews: • riparian area vegetation monitoring; and

• nest box monitoring. Lynwood Quarry has programmed the installation of nest boxes and commencement of riparian area vegetation monitoring, along with other ecological monitoring, to occur in the next reporting period.


3.12 Aboriginal Heritage

3.12.1 Annual Aboriginal Heritage Monitoring In November 2011, the Annual Aboriginal Heritage Monitoring was undertaken in accordance with the Lynwood Quarry Aboriginal Heritage Management Plan. The purpose of the monitoring was to ensure compliance with AHIP 1100264 and the AHMP. In general it was found that the majority of the sites being managed in-situ within the Holcim project boundary and outside of its approved disturbance boundary were being managed in compliance with the AHMP and AHIP #1100264. There were some exceptions, however since the November 2011 monitoring these issues have been rectified: The Cultural Heritage Management Zone was not implemented at the time of the monitoring;

however in December 2011 the area was fenced in accordance with the AHMP; During monitoring it was observed that MRN15 (#51-6-0256) and MRN PAD1 (#51-6-0687) had

been impacted by minor vehicle movements and a topsoil stockpile has also been placed in the MRN15 site area. This was notified to OEH in January 2012 and fencing and signage delineating these areas was immediately installed. No impact to Aboriginal objects was observed in either MRN15 or MRN PAD1 and therefore it is assessed that there is not a breach of Section 86 (1) or 86 (2) of the NPW Act (1974).

At the time of the monitoring the Joarimin Creek Riparian Zone (which contains 20 Aboriginal

heritage sites) was not permanently fenced. The area was demarcated by closely spaced star pickets, high visibility flagging and signage. Permanent fencing was installed around this zone in January 2012.

Three additional sites were located during the monitoring – one isolated find and two artefact scatters. Site cards have been prepared for these new sites and they will be monitored again during the next reporting period. 3.12.2 Reportable Incidents During the reporting period there were three separate incidents that were reported to Authorities where conditions of the AHIP #1100264 and AHMP had been breached. The first incident related to the installation of a water pipeline from Dam A during site

construction works. The construction of the largely above ground pipeline involved some vegetation clearing and earthworks (e.g. topsoil removal and placement of fill material). The construction of this pipeline was identified by Holcim as a potential incident as part of the pipeline was found to be located outside of the approved disturbance footprint. All works in this area were immediately ceased and the area was delineated with high visibility flagging and signage;


The second incident involved a temporary access track being near the interchange construction zone. This was identified by Holcim as a potential incident as part of the track was constructed outside the maximum disturbance boundary. All works in this area were immediately ceased and the area was delineated with high visibility flagging and signage. In addition to this all site personnel were re-inducted to enforce site responsibilities;

The most recent of these incidents was the minor impact to MRN15 (#51-6-0256) and MRN

PAD1 (#51-6-0687) which was reported to OEH as a technical breach, as no impact to Aboriginal objects was observed in this area. Following the identification of this issue, the area was fenced off and signage put in place. The completion of the access road and guardrails in this location has since created a permanent barrier to this area.

3.13 Historical Heritage No further historical heritage works have been undertaken during the reporting period. The final excavation activities were completed in June 2011, at the site of the Old Marulan Township on the Hume Highway in accordance with a S65A application under the Heritage Act (2009/S65A/13). The final excavation report is due to be submitted in September 2013, as approved by OEH in September 2012. Further details regarding the Historical Heritage of the site are contained within the EIS, SEE and EA for the Lynwood Quarry. 3.14 Bushfire Lynwood Quarry infrastructure areas are protected from bushfire by the provision of fire hydrants, extinguishers and hose reels in appropriate locations on site and are maintained in accordance with OH&S guidelines. The construction contractor operates at least two water carts, which will be used for fire fighting as required. Firebreaks will be maintained and constructed as required and will not be established within habitat management areas. 3.15 Public Safety

The following measures have been implemented at Lynwood Quarry to minimise the risks to the public and ensure public safety: the site is fenced;

access points to the site are gated, and are locked after hours; access points to the site have security signs and warning signs;

a “gate-keeper” is employed to man the gate during construction hours to direct site visitors and

ensure site personnel are made aware of visitors; all visitors to the site must sign in and out at either the construction contractors’ office or at the

Lynwood Quarry Holcim Office; the site is under video surveillance;


all vehicles entering the site from Wilson Drive entrance are stopped at the gate and are required to call or radio to be escorted onto the site; and

site access roads used by heavy vehicles have restricted access.

3.16 Waste Management

Waste management at Lynwood Quarry during the reporting period was undertaken in accordance with the BMD Lynwood Quarry Construction Waste Management Plan. The Plan outlines the procedures for the monitoring, minimisation, classification and disposal of waste during construction activities. The Waste Management Plan also outlines the actions and responsibilities applicable to all waste management processes conducted onsite. Waste details are also recorded onsite through the implementation of a waste register, which includes:

the classification of waste; how and where the waste is to be reused / recycled, stockpiled and disposed of; the receptacles that will be used for storing the reused, recycled, stockpiled or disposed of

material; and the method of transport, the company, the storage methods and the method of treatment for

all wastes handled on the site.

3.16.1 Sewage Treatment and Disposal

The Lynwood Quarry sewage treatment system consists of onsite sewage storage tanks. The tanks are pumped out weekly by a licensed contractor for disposal at an appropriately licensed waste water treatment facility. 3.16.2 Waste Disposal and Recycling

Waste is placed in general waste bins, the bins are collected on a regular basis by an authorised waste disposal contractor. Waste is recycled and reused where appropriate, in accordance with Conditions 53 and 54 of Schedule 3 of the Lynwood Quarry development consent. Recyclables from the offices are separated and taken to an appropriately licensed waste facility for processing. 3.17 Hazardous Material Management

Hazardous materials utilised during the construction phase at Lynwood Quarry are utilised in accordance with specific environmental management sub-plans developed by the construction contractor. Hydrocarbon materials for construction activities are contained within a Hazardous Materials (HAZMAT) container held onsite by the construction contractor. The container also holds the relevant MSDS for each material. Diesel is stored in a fuel trailer which also contains a spill kit for spillages that may occur. No spills were recorded during the Annual Review period.


Hazardous Materials utilised on site were managed in accordance with the relevant regulatory requirements during the report period. Maintenance on construction vehicles is generally undertaken at the construction contractors’ workshop which is located offsite. 3.18 Feral Animal Control Feral fauna species will be visually monitored during the Lynwood Quarry Environmental Officer’s regular inspections and during fauna surveys undertaken once every three years. Measures to control feral species will be implemented as required and in consultation with the Rural Lands Protection Board, where necessary. No feral animal control works activities were required to be undertaken during the reporting period. 3.19 Weed Control Areas not subject to quarrying activities will be subject to six monthly weed assessments by the Environmental Officer. Outbreaks of weeds, in particular noxious weeds as defined by the Noxious Weeds Act 1993, will be controlled using suitable control measures such as spraying, slashing or manual removal. During the report period, spraying for tussock grass was undertaken.


4.0 Community Relations

Lynwood Quarry has established a Community Consultative Committee (CCC) in accordance with Conditions 9 and 10 of Schedule 5 of DA 128-5-2005. During the reporting period, two CCC meetings were held on 10 October 2011 and 12 March 2012. The main focus of the meetings was: • an update on construction progress;

• a review of environmental performance; and

• an update regarding the ongoing community consultation process for the site.

4.1 Community Complaints

Nine community complaints were received by Lynwood Quarry during the report period. The details of the complaints are provided in Table 4.1, below.

Table 4.1: Community Complaint Details

quarry

4.2 Community Donations The following donations were made to the local community during the reporting period. Contributions from Holcim’s nearby Johnnifelds Quarry have been included in this summary, as the Johnnifelds Quarry is also located in Marulan and therefore targets the same community:

• $500 contribution to PCYC program aimed at preventing youth crime; • $500 donation to Marulan Christmas Family Fun (Johnnifelds) • $1000 donation to the Marulan Football Club (Johnnifelds) • $500 donation to the Goulburn North Family Fun and Fireworks Night (Johnnifelds)


5.0 Rehabilitation Activities During the reporting period temporary land shaping, seeding and other revegetation works were undertaken in disturbed areas to minimise the potential for offsite impacts associated with the migration of windblown dust, particularly in regard to topsoil stockpiles and stripped soil surfaces not required for operational use. Topsoil stockpiles were seeded to minimise the potential for loss of soil through wind or rainfall erosion. In addition to this, an extensive area of new surfaces created during construction were topsoiled and seeded – these areas included over 20ha of road batters, table drains, and diversion drains.

Figure 1: Rehabilitated Former Asphalt area at Interchange

Opportunities for future rehabilitation in the next 12 months will be increased due to the civil construction phase coming to an end and the remaining construction activities confined to the future infrastructure areas. Further detail on the proposed progressive rehabilitation during quarrying operations and the conceptual final land use for the site are provided in the Lynwood Quarry Rehabilitation and Landscape Management Plan.


6.0 Activities Proposed for 2012/13 Annual Review Period The following construction works are programmed for the next Annual Review period: • Completion of all civil works including:

Hume Highway Interchange; Site Access Road; Rail siding; and Electrical infrastructure.

• Commencement of processing plant and associated equipment, including:
