6.0 FURTHER WORK SINCE PREPARATION OF MY REPORT
19. Since completing my HA report, I reviewed of the results of more recent groundwater chemical analyses and filter cake soil chemistry leaching column studies to ascertain whether placement of filter cake into the proposed dredge pond would pose unacceptable risk to groundwater (discussed in Section 12). I also prepared additional mapping of the water table beneath Deep Creek to aid in understanding the relationship between the creek bed and underlying groundwater (included in Chapter 12).
7.0 HA REPORT SUMMARY AND CONCLUSIONS
20. WA1488 is in a coastal aquifer hydrogeological setting. The regional water table beneath the majority of the site occurs within Brighton Group sediments. Groundwater flows towards and discharges into Western Port Bay.
21. The site is bounded by two creeks, Deep Creek to the north and Colbert Creek to the south. Flow in both creeks is ephemeral, only occurring after extended rainfall events.
22. The water table is below the creek beds only intersecting streambed at lower elevations west of the Bass Highway.
23. DPQ will require additional water for sand washing and processing under the ERR endorsed Work Plan Variation for WA1488. The additional water would be sourced from groundwater either pumped directly from the dredge pond or recovered from the sand feed (mostly from dredged slurry). DPQ have negotiated a temporary groundwater licence transfer for 80.5 ML per annum.
24. Groundwater recharge at WA1488 has been increased by the development of the existing FMSEP as a result of the removed of the silt/clay overburden and exposure of the underlying more permeable sand. Recharge will be further increased (enhanced) as the proposed footprint of the existing FMSEP increases and with development of the proposed eastern CSEP.
March 2021 Planning Permit Application 120388-1 5 GW-21/003 Expert Evidence - Hydrogeology – John Leonard 003167
JOHN LEONARD CONSULTING SERVICES GROUNDWATER AND ENVIRONMENTAL CONSULTANTS
25. The resulting increased groundwater storage will be reduced by evaporation from the free water surface in the proposed FMSEP dredge pond and by water deficit associated with sand processing of about 65 ML/year as well as by the future use of groundwater pumped from the FMSEP dredge pond for dust suppression (10 ML/yr).
26. Overall site and sand processing water budgets indicate that there will be a minimum net gain to the groundwater system of about 136 ML per annum resulting from increase rainfall infiltration into the exposed sands or the dredge pond. Consequently, local drawdown interference is not expected to occur.
27. The findings of groundwater quantity and quality risk assessments were that most potential risks are in the Low Risk category, and that Risk Mitigation measures would result in Low Residual Risks.
28. I confirm my opinion that the proposed WA1488 variations will not adversely impact groundwater quantity, groundwater quality, flow in Deep Creek, and/or discharge into Western Port Bay.
8.0 DECLARATION
29. I have made all the inquiries that I believe are desirable and appropriate and no matters of significance which I regard as relevant have to my knowledge have been withheld from the Panel. In preparing this report I have read and had regard to the PPV Expert Witness Practice Note dated April 2019.

9.0 BACKGROUND
30. The HA report that I prepared focused on assessing the Environmental Risk to groundwater and the interconnected surface water systems associated with development of the endorsed Work Authority variation for WA 1488 particularly use of groundwater in sand processing works and for on-site dust suppression. In this context, I point out that at the time that I prepared my HA report, DPQ were in the process for applying for a temporary licence for 80.5 ML per year under the provisions of the Water Act 1889 and trading rules established for the local water management area, i.e., the Koo Wee Rup Water Supply Protection Area administered by Southern Rural Water (SRW). A temporary licence subject to annual review was subsequently granted by SRW.
31. In preparing my report, I addressed the requirement of both the “Preparation of Work Plans and Work Plan ― Variations Guidelines for Mining Projects” prepared by the Department of Jobs, Precincts and Regions (DJPR, V12, 2019), and the Water Act 1989 (as amended).
32. The DJPR (2019) guidelines requires that descriptions must be included in WA variation documents of (but not limited to) 1) the nature of any new auxiliary works, e.g., dewatering bores, and water treatment plant that could adversely impact local groundwater systems, 2) the location of sensitive hydraulically connected receptors such as water supply bores and Groundwater Dependent Ecosystems within two kilometres of the licence boundary relevant to the new or changing works, and 3) an assessment of the risk of harm arising from the proposed changed operations to local groundwater users and hydraulically connected sensitive environmental segments such as wetlands or Groundwater Dependent Ecosystems (GDEs).
33. The provisions of the Water Act 1989 require that potential groundwater users obtain 1) a license to construct a bore, and 2) a separate licence to take and use groundwater for commercial uses. [Extracting groundwater for stock watering and/or domestic use is a statutory right under the Water Act and does not require an extraction licence.] Licensing authorities are also required to ensure that allocation of a new groundwater licence does not undermine environmental water reserves or surface water allocations. In considering applications for a groundwater extraction licences the Rural Water Authorities including SRW have to take a number of matters into consideration including, 1) the existing and projected availability of water in the area, 2) any adverse effect that the allocation or use of water under the entitlement is likely to have on existing authorised uses of water, a waterway or an aquifer, 3) the need to protect the environment, including the riverine and riparian environment, and 4) government policies concerning the preferred allocation or use of water resources.
10.0 CONTEXT AND GROUNDWATER CHARACTERISTICS
34. Key earth system components that I considered in my HA report included climate, topography, surface and subsurface geology, aquifer type and form, aquifer spatial distribution, and aquifer hydraulic parameters. Climate, especially rainfall and evaporation, control the amount of water available to recharge aquifer systems. The
March 2021 Planning Permit Application 120388-1 7 GW-21/003 Expert Evidence - Hydrogeology – John Leonard 003169
JOHN LEONARD CONSULTING SERVICES GROUNDWATER AND ENVIRONMENTAL CONSULTANTS
amount of recharge together with other stresses on groundwater systems and aquifer hydraulic parameters in turn control the depth to groundwater. Topography is not only one of the main controls on surface water runoff but also has a significant influence on water table position; the water table configuration is a subdued reflection of the surface topography. The influence of topography is more pronounced in hilly and mountainous terrain with high relief. Direct groundwater discharge occurs where the water table intersect the ground surface or indirectly via evapotranspiration where the water table is close to the ground surface. The geological history of an area controls the number and type of aquifers, their lateral and vertical extent, and configuration (depth, outcrop pattern), hydraulic properties and degree of interconnection. Surface/outcrop geology controls the recharge/discharge regime of aquifer systems whilst subsurface geology controls the distribution and flow of groundwater. Subsurface geology also controls possible development of perched water tables above the main regional water table.
Climate
35. The climate in the Grantville area is temperate and variable with moderate rainfall received in most months. The average monthly rainfall over the 10-year period 2009 to 1018, inclusive varied between about 43.4 and 99.3 mm, and the corresponding average annual rainfall was was about 932 mm.
Topography and Drainage
36. The Grantville area is located in on a coastal plain between Western Port Bay to the west and the foothills of the Strzelecki Ranges to the east. The coastal plain is drained by a number of small general east-west aligned “streams” including Deep Creek along the northern boundary of WA1488 and Colbert Creek along its southern boundary that discharge into Western Port Bay (Figure 1). The pre-quarrying elevation across WA1488 ranged from less than 10 m AHD in the northwestern part of the site up to more than 120 m AHD on the ridge in the eastern portion of the site (Figure 2).
37. The channel of both Deep Creek and Colbert Creek are incised and well defined with a number of shallow depressions in the streambed; small, disconnected pools form in the depression after rainfall events. Both streams were dry except for some on- and off- stream dams and small, natural water holes, and relatively short reaches close to Western Port Bay when inspected during field reconnaissance in 2012-3, 2017, 2018, and 2019.
Geology
38. The geology varies across the WA1488 site with the western, larger portion (~124.0 ha) of the site located within the Western Port Basin and smaller eastern portion (~31.6 ha) is within the Gippsland Basin. The two basins are separated by the general northeast- southwest aligned Heath Hill Fault. Movement on the Heath Hill Fault has juxtapositioned younger, unconsolidated Tertiary Brighton Group against consolidated and indurated Cretaceous Strzelecki Group Rocks that outcrop east of the Heath Hill Fault (Figure 3) and is the predominate rock type that forms the Strzelecki Ranges.

39. The Brighton Group beneath WA1488 was not fully penetrated during sand resource investigative drilling undertaken by BCA between 2011, 2017 and 2018. However, based on review of bore logs in the (greater) Grantville area, the stratigraphic sequence beneath WA1488 is considered to consist of (from oldest to youngest): 1) Strzelecki Group, 2) possibly Childers Formation (thin brown coal was reported in a number of bores in the Grantville area), and Brighton Group.
40. The Brighton Group east of the Heath Hill Fault consists of unconsolidated sands, silts and clays with up to 4-10 m of silt and clay “overburden” overlaying fine-medium sand in the western portion of WA1488, with thinner to absent overburden above the coarse sand in the more elevated eastern portion of the site closer to the Heath Hill Fault.
41. A thin veneer of Brighton Group overlies older Cretaceous consolidated Strzelecki Group rocks on the eastern side of the Heath Hill Fault. A volcanic plug intruding Strzelecki Group rocks was intersected in drillholes immediately east of the Heath Hill Fault (these drillhole were logged by R Anderson).

Hydrogeology
42. The hydrogeology of WA1488 and the surrounding area is described in detail in HA report Chapter 7 and summarised in this Section.
43. The water table beneath WA1488 occurs within the Brighton Group west of the Heath Hill Fault, and in the Strzelecki Group east of the fault. Shallow groundwater intersected in bores immediately east of the Heath Hill Fault is consider to be perched above the deeper regional water table.
44. The water table within the Brighton Group slopes in a general westerly direction towards Western Port Bay. The salinity of the groundwater in the Brighton Group beneath WA1488 was less than 500 mg/L TDS. The horizontal hydraulic conductivity of the Brighton Group fine to medium sands determined from the grain size analyses undertaken by BCA is in the general range 20 to 30 m/day. The hydraulic conductivity of the coarse sand facies in the eastern portion of WA1488 would be higher possibly up to 50 m/day. Rainfall recharge under per-quarrying conditions was variable with high infiltration rates (25 to 30%) on the more elevated eastern portion where Brighton Group sands outcrop or subgroup beneath a thin layer of silt and clay, and lower (less than 15-20) in the flatter-lying western portion of the site where sand is overlaid by a thicker layer of silt and clay. Groundwater recharge at WA1488 has been increased by the development of the existing FMSEP as a result of the removed of the silt/clay overburden and exposure of the underlying more permeable sands.

45. Groundwater discharges mainly into the Western Port Bay over a relatively wide discharge/transition zone, into local creeks where the base of the creeks are below the water table, or via evapotranspiration near the bay where the water table is close to the ground surface. The water table is below the base of both creeks that bound WA1488 (Deep Creek along the northern boundary and Colbert Creek along the southern boundary). The water table only intersects the streambed of these creeks very close to Western Port Bay.

11.0 THE PROPOSED FURTHER DEVELOPMENT AND SUPPORTING DOCUMENTATION, INCLUDING THE PROPOSALS TO INTERSECT GROUNDWATER AND EXTRACT SAND BELOW THE GROUNDWATER TABLE
46. The ERR endorsed variation includes 1) increasing the area of the western, fine-medium extraction sand pit (FMSEP) above water table and dredging sand from the extended central area of the pit (dredge pond) using a dredge cutter, and 2) development a new coarse sand extraction pit (CSEP) at higher elevation and more than 40 m above the water table in the eastern portion of the approved site in area (Figure 4). The final dredge pond within the FMSEP will cover about 24.1 ha and contain about 3,500 ML of water.

JOHN LEONARD CONSULTING SERVICES GROUNDWATER AND ENVIRONMENTAL CONSULTANTS
47. The dry screening and blending sand plant will be significantly enhanced enlarged to process both wet sand slurry from the proposed FMSEP dredge pond as well as “dry” sand from the FMSEP areas above the water table and “dry” coarse sand from the CSEP. The processing plant will include a sand wash plant, thickener and water clarifier, mud buffer tank, dewatering belt press, fresh water storage tank and recycled water storage tank (recycled water will be returned to the dredge pond).
48. Groundwater will be removed from the pond in the slurry (25% sand and 75% water) dredged from the pond and pumped to the sand washing plant for processing. Groundwater will also be pumped directly from the pond for sand processing make-up water and for dust suppression.
49. The plant at WA1488 will be enlarged to process both slurry from the proposed FMSEP dredge pond. Dry sand will continue to be extracted above the water table from an expanded FMSEP and blended with sand from the proposed CSEP. The enhanced sand washing, and dewatering plant will incorporate the existing raw bulk feed bin system with the addition of constant density feed regulating sumps, cyclones, wet sizing and dewatering screens, water clarifier and thickening tank, mud buffer tanks, process water and make-up tanks, a dewatering belt press.).
Net Water Loss
50. For the purposes of my HA report, I analysed the highest water “losses” scenario which was for a combination of 220 dry tonnes per hour (dtph) of “wet” sand (25% sand and 75% water slurry) from the FMSEP dredge pond and 109 dtph of “dry” sand quarried from pit areas above the water table in both the FMSEP and the CSEP. [A sand and water budget process flow diagram for this scenario is presented in Figure 9.1 on page 63 of my HA report].
51. The net water lost from the combined sand extraction and process system under the highest water loss operating scenario would be 34 m3/hr. The corresponding annual water lost for 8-hour work day, 5-days per week for 48 weeks per year would be 65,280 m3 or about 65 ML. Dust suppression would require an additional conservatively estimated 10 ML per year.
52. The total water use would therefore be about (65 + 10 =) 75 ML/yr
Pit Storage Volume
53. I estimated the volume of water stored in the final pit to be about 3,500 ML (see calculations on page 64 of my HA report).
Net Change in Groundwater Storage
54. I used a simple annual groundwater balance approach considering a range of infiltration rates to estimate the change in groundwater storage from increased (enhanced) recharge over the areas of the proposed pits between pre-quarrying and proposed ultimate pits
March 2021 Planning Permit Application 120388-1 13 GW-21/003 Expert Evidence - Hydrogeology – John Leonard 003175
JOHN LEONARD CONSULTING SERVICES GROUNDWATER AND ENVIRONMENTAL CONSULTANTS
considering both plant processing and dust suppression water losses. For the purpose of the simplified water balance, the other water balance components (runoff, evaporation, evapotranspiration) are lumped as non-infiltrated rainfall. The infiltration rate for the ultimate pit conditions after the low permeability overburden is removed was considered to be 100%, i.e., all rain that falls over these areas becomes groundwater via infiltration in pit areas above the water table, and rain that falls on the FMSEP dredge pond becomes groundwater storage (the exposed water in the dredge pond would be a “window” into the water table). Annual evaporation from the exposed water table in the dredge pond and the total water use volume (75 ML) were subtracted from the enhanced recharge to estimate the annual change in groundwater storage. The net Annual Change in groundwater storage for analysed infiltration rates of 15%, 20%, 25% and 30% were about 241, 206, 171 and 136 ML, respectively. The assumptions that I used and example calculations were presented on page 66 of my report.
12.0 WHETHER THE PROPOSED FURTHER DEVELOPMENT WILL CAUSE ANY UNREASONABLE GROUNDWATER IMPACTS
Groundwater Resource Impacts
55. I used three different analysis methods to investigate drawdown and associated drawdown impacts, namely:
1. Analytical modelling of drawdown induced by pumping the DPQ licensed allocation of 80.5 ML from a single bore. 2. Instantaneous extraction of 80.5 ML from the proposed FMSEP. 3. Worst case analysis – all processing and dust suppression water sourced from the FMSEP dredge pond but with no associated increased (enhanced) recharge. 4. Enhanced Recharge Net Groundwater Storage analysis.
Drawdown Analytical Modelling
56. The drawdown induced assuming that the calculate daily volume of 335.4 m3 (≈ 0.335 ML) was extracted from a bore located at the approximate centre of the proposed FMSEP dredge pond pumping at a rate of 11.65 L/sec for 8 hours was determined using the Theis nonequilibrium analytical modelling equation. This analysis assumed conservative saturated aquifer thickness and storativity of 80 m and 0.001 (dimensionless), respectively, and an aquifer hydraulic conductivity of 25 m/day derived from grain size analysis data. The modelled time-drawdown data and data plots for radii of 350, 700 and 1050 m from the theoretical pumping bore are presented in Figure 5. [The drawdown at Western Port Bay about 1,050 m from the theoretical bore after pumping for 8-hours would be about 0.025 m.] The water level would recovery during the intervening period before extraction commences on the next day.

Instantaneous Dredge Pond Water Level Decline
57. I further assed the worst-case drawdown impact by assuming that the licensed allocation of 80.5 ML (80,500 m3) was pumped instantaneously directly from the proposed FMSEP dredge pond. The FMSEP dredge pond will have a surface area of about 24.1 ha, water depth of about 17 m and contains about 3,500 ML of water. A volume of 80.5 ML is about 2.3 per cent of the volume ow in the proposed dredge pond. The change in the water depth (∆d) in the dredge pond (surface area of 241,000 m2) assuming that all the sought allocation of 80,500 m3 is removed instantaneously directly from the pond (worst case scenario and physically not achievable) would be (241,000 x ∆d = 80,500) would be about 0.33 m. Applying the same instantaneous extraction analysis for the volume of groundwater extracted during an 8-hour working day of (41,927 x 8 ≈) 335.42 m3, the change in water depth would be (241,000 x ∆d = 335.42) 0.0014 m, or 1.4 mm (not measurable in the field).
All Water From Dredge Pond, No Enhanced Recharge
58. The worst-case water “loss” from the endorsed WA1488 variation would be for all water lost during sand processing and consumptive use (e.g., dust suppression) to be sourced from groundwater in the FMSEP dredge pond with no offset from the enhanced recharge that will occur under proposed quarrying conditions. The highest water “loss” from sand processing would be for a sand feed blend from both the dredge pond slurry at an input rate of 220 dtph and dry sand quarried above the water table at 109 dtph. The net water loss from this combined feed input would be 34 m3/hr (0.034 ML/hr) or
March 2021 Planning Permit Application 120388-1 15 GW-21/003 Expert Evidence - Hydrogeology – John Leonard 003177
JOHN LEONARD CONSULTING SERVICES GROUNDWATER AND ENVIRONMENTAL CONSULTANTS
65.280 ML annually assuming that the quarry will operate 8-hours a day, 5-days a week for 48 weeks per year. Dust suppress watering will require a conservatively estimated 10 ML/yr. The total annual water deficit would therefore be about 75 ML.
59. The maximum extraction over an 8-hour day would result in the greatest drawdown interference as the water level would recover during the subsequent 16-hour non- pumping period. The highest daily water loss associated with sand production would therefore be (0.034 x 8 =) 0.272 ML. Assuming that dust suppression will only occur every working day during the 6-month period September to February (120 working days), the daily usage would be (10 ÷ 120 =) 0.08 ML. The highest total daily water deficit would therefore be (0.272 + 0.08 =) 0.352 ML (equivalent to 12.22 L/sec).
60. The drawdown after 8-hours continuous pumping at a rate of 12.22 L/sec 350 m, 700 m and 1,050 m from an imaginary pumping bore located at the approximated centre of the proposed dredge pond would be about 0.14, 0.06 and 0.03 m, respectively (Figure 6).

FIGURE 6 Daily Time-Drawdown Data Plots, Deficit Rate = 12.22 L/sec
Net Groundwater Storage Change
61. In order to assess the realistic impact of the water deficit (processing loss plus dust suppression water) the increased groundwater storage has to be taken into account. The process and groundwater balances that I presented in Chapter 9 of my HA indicated that the total change in groundwater storage [(enhanced recharge; 487 ML/yr) minus evaporation loss (276 ML/yr) minus water use deficit (75 ML/yr)] for worst case pre- quarrying infiltration (30% rainfall) would be a gain of 136 ML per year.
March 2021 Planning Permit Application 120388-1 16 GW-21/003 Expert Evidence - Hydrogeology – John Leonard 003178
JOHN LEONARD CONSULTING SERVICES GROUNDWATER AND ENVIRONMENTAL CONSULTANTS
62. As the change in groundwater storage is positive, the removal of groundwater in the FMSEP dredged sand slurry and by direct pumping of water from the dredge pond will not cause adverse drawdown interference around the pond. Consequently, the proposed variations to WA1488 Work Plan will not adversely impact local groundwater users.
Groundwater Quality Impacts
General
63. I assessed potential impacts on groundwater quality as part of the “Groundwater Contamination Risk Assessment” (GCRA) in my HA report using industry standard Source-Pathway-Receptor-Consequence (SPRC) SPRC approach (refer HA Report Section 11.4).
64. Potential contamination sources or events that I considered were, 1) leaking fuel storage tanks and/or fuel spills, 2) leakage and/or spills of stored processing chemicals, 3) chemicals in in water returned to the FMSEP dredge pong (discussed in more detailed in this Statement based on data obtained subsequent to completing my HA report), and 5) dredge incident.
65. Most of the assessed risks were in the no/low or medium risk ranking. The exception was a high risk ranking associated with potential leaking fuel tank of fuel spill.
66. I consider that adapting risk mitigation measures as listed below would reduce all risks to no/low ranking
• All fuels and other chemicals will be stored in compliance with 1) Hydrocarbon storage in accordance with AS 1940 (The Storage and Handling of Flammable and Combustible Liquids) and 2) the Dangerous Goods (Storage and Handling) Act. • Underground fuel storage tanks will not be used. • Vehicle refuelling will only be in bunded hardstand containment areas • Contaminant spill kits will be kept onsite. • All machinery and equipment including the cutter dredge will be regularly checked and maintained to minimize the potential for equipment failure. • Drip trays will be used on the cutter dredge to contain accidental spills when refuelling or changing hydraulic fluids.
Specific to possible disposal of filter cake in FMSEP dredge pond
67. An option considered by DPQ after I completed my HA report involves disposing filter cake from the sand processing operations into the water in the FMSEP dredge Pond. The filter cake would contain heavy metals derived from the original sand feed and possibly residual coagulants and flocculants used in processing the raw sand.
March 2021 Planning Permit Application 120388-1 17 GW-21/003 Expert Evidence - Hydrogeology – John Leonard 003179
JOHN LEONARD CONSULTING SERVICES GROUNDWATER AND ENVIRONMENTAL CONSULTANTS
68. Subsequent to preparing my 2019 HA report, DPQ had a sample of filter cake analysed for soil chemical composition and subjected a sample to column leachate testing by two laboratories, Eurofins Environmental Testing (Eurofins) and ALS Environmental (ALS). The analyte suite for both the soil and leachate from the column test was comprehensive. The leachate column tests analytical method were conducted in accordance with AS 4439.3.
69. Most of the chemical concentrations in the leachate from the column test were less than the Limit of Report (LOR).
70. The concentrations of heavy metals in the leachate sample analysed by Eurofins are presented in Table 1.
TABLE 1 Heavy Metal Concentrations in Filter Cake Leachate, Eurofins Report 742427-L Extract
March 2021 Planning Permit Application 120388-1 18 GW-21/003 Expert Evidence - Hydrogeology – John Leonard 003180
JOHN LEONARD CONSULTING SERVICES GROUNDWATER AND ENVIRONMENTAL CONSULTANTS
71. The concentration of the tested heavy metals in the Leachate sample analysed by Eurofins were mostly less than respective LOR, and were similar or less than the concentrations in the ambient groundwater at WA1488.
72. I also read the reply to DPQ from the SFN Australian Pty Ltd dated 2 March 2021 (copy below) regarding the use of the proposed polymers (EMA8335) and coagulants (FL4440) at other sites in particular at potable water treatment plants to settle and dewater solids. Victorian Water Authorities using similar chemicals include Melbourne Water, Gippsland Water, South Gippsland Water, Western Water, Barwon Water, and Central Highlands Water. Based on this information, I consider that the use of polymers at WA1488 would not contaminate groundwater in the filter cake is emplaced in the FMSEP dredge pond or have associated unacceptable risks of environmental harm.
13.0 ANY ISSUES RAISED IN THE OBJECTIONS TO THE AMENDMENT APPLICATION THAT ARE WITHIN YOUR EXPERTISE.
73. I read all of the objections in he Hearing Book. I searched the objections using a variety of keywords (groundwater, water table, etc.) to identify objections related to my expertise. I grouped the objections into five general and in part overlapping categories, namely:
1. Effects on flow in Deep Creek; 2. Reduce groundwater availability in an aquifer that is fully allocated; 3. Adverse effects on groundwater quality 4. Adverse impact on the groundwater flux into and the quality of waters of Western Port Bay; and 5. Need for Independent review of WA1488 Hydrogeological Assessment Report.
Flow in Deep Creek
74. I presented multiple lines of evidence including field observations, topographic analysis using high accuracy Lidar elevation data, and water table mapping to demonstrate that Deep Creek is a losing stream that only flows intermittently after rainfall events. My analysis indicated that the water table does not intersect the creek bed until the creek tract downstream from Bass Highway. Reconnaissance surveys along this portion of Deep Creek suggested that the creek would only become a gaining stream below elevation of about 2-3 metres Australian Height Datum (m AHD).
75. Deep Creek upstream of the Bass Highway is incised and well defined with a number of shallow depressions in the streambed; small, disconnected pools form in the depression after rainfall events (Plate 1).
76. I prepared Figures 7, 8 and 9 for my Evidence Statement to visualise the spatial relationship between the bed of Deep Creek and the underlying water table to further demonstrate that the any water table drawdown at WA1488 would not impact flow in Deep Creek.

JOHN LEONARD CONSULTING SERVICES GROUNDWATER AND ENVIRONMENTAL CONSULTANTS
Groundwater allocation
77. One objector was concerned that DPQ were granted a groundwater extraction licence even though groundwater is fully allocated.
78. The WA1488 is within Zone 7 Coastal Buffer of the Koo Wee Rup Water Supply Protection Area (KWR WSPA). The amount of groundwater that can be extracted annually from Zone 7 has been fully allocated (actual groundwater usage in Zone 7 has historically been less than 40 per cent of the total allocated volume). DPQ have obtained a licence to “Take and Use” 80.5 ML per year by Temporary Water Trading under the provisions of the Water Act 1989 (as amended). The temporary licence is subject to annual review by SWR as delegated manager for water resources across southern Victoria.
Impacts on groundwater quality
79. See discussion in Section 11 of my Statement for response regard potential impacts on groundwater quality
Western Port Bay
Impact on groundwater discharge flux
80. Groundwater flow tubes that pass beneath WA1488 discharge into the near off-shore zone in Western Port Bay. The discharge zone is located at a minimum more than 600 m from the western edge of the final FMSEP. [I consider that the main discharge most likely occurs further offshore because of the large linear extent of the advance and retreat of seawater across the relatively extensive tidal mud flats in the bay in the Grantville area.] The various analyses that I undertook to assess the likely drawdown associated with future use of groundwater by DPQ showed that drawdown, if any, along the Western Port Bay shoreline under a variety of different scenarios would very small, less than about 3 cm (and difficult to differentiate from other process that cause water table fluctuations). Consequently, the use of groundwater at WA1488 will not adversely impact the groundwater flux into the bay.
Impact on Western Port Bay Water Quality
81. Based on the findings of my GCRA prepared as part of my HA report, I consider that the risks of contamination arising from sand quarrying operations at WA1488 affecting the quality of the water in Western Port Bay via groundwater pathways would be very low and that the associated risks are acceptable.
Independent Review of Hydrogeological Assessment Report
82. One objector advocated that my HA report should be independently reviewed.
March 2021 Planning Permit Application 120388-1 23 GW-21/003 Expert Evidence - Hydrogeology – John Leonard 003185
JOHN LEONARD CONSULTING SERVICES GROUNDWATER AND ENVIRONMENTAL CONSULTANTS
83. My HA report was reviewed by an experienced hydrogeologist with Earth Resources Regulation as part of their regulatory review of the WA1488 variation documents. It was also reviewed by SRW when considering DPQ’s application for a temporary groundwater Take and Use licence; SRW were required to be satisfied that the matters required under the Water Act 1989 had been addressed and use of groundwater would not have adverse impacts on other local groundwater users and/or the environment.
14.0 THE NEED FOR ANY ADDITIONAL WORKS OR OTHER MEASURES TO MITIGATE ANY POTENTIAL GROUNDWATER IMPACTS.
General Groundwater Monitoring Bore Network
84. The current groundwater bore network is considered to be generally adequate to monitor the impact of the endorsed WPV on groundwater. However, one of the existing bores will be removed as the FMSEP is expanded. Consequently, I recommended that a replacement bore should be installed. I consider that the replacement bore should be sited down the hydraulic gradient to the west of the FMSEP dredge pond. I also recommended that an additional monitoring bore should be installed to the south of the FMSEP near the WA1488 site boundary with the Parks Victoria, Grantville Bushland Reserve.
Groundwater quality monitoring
85. The suite of analytes tested in groundwater should be include all chemicals used on site.
Filter cake and leachate analysis
86. Testing of representative samples of the filter cake from the proposed sand processing after the plant has been upgraded should be undertaken and leachate column tests conducted to ascertain whether the filter cake produced by the proposed expanded sand processing plant would cause water contamination if emplaced below the water table in the FMSEP dredge pond. If the findings of the additional testing indicates that the risk of environmental harm associated with disposal below the water table would be unacceptable, alternative disposal methods such as above ground on-site disposal or off- site disposal to a suitably licenced facility would be required.
Risk Mitigation Measures
87. If any potential groundwater contaminating events such as chemical spills occur, DPQ should initiate works to either remove or control the potential contamination source, install investigation/monitoring bores down hydraulic gradient from the source if existing bore are not suitably located and analyses groundwater samples for Chemicals of Concern associate with the source to determine water quality impacts. If the analyses indicate contamination, the risk assessment should be up-dated to determine whether the risk of harm has become unacceptable. If the risks are unacceptable DPQ should instigate clean-up measures appropriate to the source characteristics to rehabilitate any contaminated groundwater to the extent practicable or until the risks are acceptable.

15.0 THE ISSUES SET OUT IN PARAGRAPHS 6 AND 19 OF THE DIRECTIONS TO THE EXTENT WITHIN YOUR EXPERTISE
88. No issues that were raised in Paras 6 and 19 of the Directions that are relevant to my area of expertise in hydrogeology.
16.0 ANY OTHER GROUNDWATER MATTERS YOU CONSIDER RELEVANT TO THE ASSESSMENT OF THE PROPOSED FURTHER DEVELOPMENT
89. No other matters have been raised that are relevant to the WPV in my area of expertise in groundwater management.
17.0 HA REPORT SUMMARY AND CONCLUSIONS
90. WA1488 is in a coastal aquifer hydrogeological setting. The regional water table beneath the majority of the site occurs within Brighton Group sediments. Groundwater flow towards and discharges into Western Port Bay.
91. The site is bounded by two creeks, Deep Creek to the north and Colbert Creek to the south. Flow in both creeks is ephemeral, only occurring after extended rainfall events.
92. The water table is below the creek beds only intersecting streambed at lower elevations west of the Bass Highway.
93. DPQ will require additional water for sand washing and processing under the ERR endorsed Work Plan Variation for WA1488. The additional water would be sourced from groundwater either pumped directly from the dredge pond or recovered from the sand feed (mostly from dredged slurry). DPQ have negotiated a temporary groundwater licence transfer for 80.5 ML per annum.
94. Groundwater recharge at WA1488 has been increased by the development of the existing FMSEP as a result of the removed of the silt/clay overburden and exposure of the underlying more permeable sand. Recharge will be further increased (enhanced) as the proposed footprint of the existing FMSEP increases and with development of the proposed eastern CSEP.
95. The resulting increased groundwater storage will be reduced by evaporation from the free water surface in the proposed FMSEP dredge pond and by water deficit associated with sand processing of about 65 ML/year as well as by the future use of groundwater pumped from the FMSEP dredge pond for dust suppression (10 ML/yr).
96. Overall site and sand processing water budgets indicate that there will be a minimum net gain to the groundwater system of about 136 ML per annum resulting from increase rainfall infiltration into the exposed sands or the dredge pond. Consequently, local drawdown interference is not expected to occur.

JOHN LEONARD CONSULTING SERVICES GROUNDWATER AND ENVIRONMENTAL CONSULTANTS
97. The findings of groundwater quantity and quality risk assessments were that most potential risks are in the Low Risk category, and that Risk Mitigation measures would result in Low Residual Risks.
98. I confirm my opinion that the proposed WA1488 variations will not adversely impact groundwater quantity, groundwater quality, flow in Deep Creek, and/or discharge into Western Port Bay.

Dear John Panel for the Grantville Quarry Application Application to Amend Planning Permit No. 120388-1 1381 – 1395 Bass Highway, Grantville We act for Dandy Premix Quarries Pty Ltd (Dandy Premix). Dandy Premix has applied to amend Planning Permit No. 120388 (the Amendment Application). That application has been called in by the Minister and will be considered at a panel hearing which has been scheduled for 22 to 25 March 2021 (inclusive), 30 & 31 March 2021, 1 April 2021, 6 to 8 April 2021 (inclusive) (Panel Hearing). 1 We confirm that, subject to confirming your fee proposal, our client wishes to engage you to prepare expert hydrogeology evidence and to appear as an expert witness at the Panel Hearing.
2 The following provides brief background information in relation to the Amendment Application. 3 An electronic copy of all relevant documents set out in the Hearing Book Index (the Hearing Book) is also provided as part of your brief.
Background 4 Dandy Premix is the owner and operator of the Grantville Quarry (the Quarry), situated at 1381 – 1395 Bass Highway, Grantville (the Subject Land), which currently operates under Work Authority No 1488 (WA1488) and Planning Permit 120388 (the Permit). 5 In order to meet its anticipated future demands for additional sand, Dandy Premix has applied to Bass Coast Shire Council (Council) to amend the Permit to facilitate further development within the existing limits of the WA1488 site boundary.
EQUIPE LAWYERS PTY LTD 8 GOLD STREET, COLLINGWOOD VICTORIA 3066 ABN 49 141 940 703
P/03 9853 5000, E/[email protected] EQUIPELAWYERS.COM.AU 003208 6 WA1488 contains a State significant sand resource. In recognition of its strategic importance to the Victorian economy, the Quarry and its proposed further development (the Proposed Further Development) were included on the Extractive Industry Priority Project List. A copy of the Extractive Industry Priority Project List is contained in Tab 168 of the Hearing Book. 7 The WA1488 area contains an estimated total resource of 76,000,000 tones and is situated within an identified Melbourne Supply Area Extractive Industry Interest Area. 8 Dandy Premix anticipates that total production in 2021 will be approximately 500,000 tonnes and this will increase to 750,000 to 800,000 tonnes per annum in 2026 if the Permit is amended.
9 Significant increases in the demand for construction sands in recent years has meant that sand reserves in the areas approved under the Permit have depleted at faster than expected rates such that the approved resource is likely to be exhausted by 2023 at the current rate of production.
10 In order to extend the life of the Quarry and to meet its anticipated future demand for sand, Dandy Premix proposes to access additional reserves within the existing Work Authority boundary by: 10.1 further developing the existing fine-medium sand extraction pit (FMSEP), including extracting sands from below the water table; and
10.2 establish a new coarse extraction sand pit (CSEP) and 10.3 washing sands on site, which will require a new sand washing and dewatering plant and associated infrastructure works within this boundary;
10.4 introducing a signalised intersection. 11 The Proposed Further Development would secure access to an approximate additional 30,000,000 tonnes of sand resource and ensure that the Quarry can continue to meet current and forecast rates of production into the future. 12 Whilst the Proposed Further Development will necessitate some Native Vegetation removal, it will be offset through extensive existing native vegetation offsets which will be set aside on the Subject Land and/or on adjoining land owned by Dandy Premix. The offset vegetation may be protected in perpetuity as First Party Offsets under an agreement made under section 69 of the Conservation Forests and Lands Act 1987 security agreement with the Secretary, Department of Environment, Land, Water and Planning (DELWP). The Subject Land 13 The Subject Land is located at 1381 – 1395 Bass Highway Grantville. It is located on the eastern side of the Bass Highway approximately 1 km to the north of the Grantville township.

14.2 Crown Allotment 176B Parish of Corinella (Vol 07824 Folio 032) 14.3 Lot 2, PS 300991J (Vol 10031 Folio 148)
14.4 Lot 4, PS 604744H (Vol 11044 Folio 475) 14.5 Lot 5, PS 604744H (Vol 11044 Folio 476) 14.6 Lot 1, TP 515206V (Vol 08869 Folio 053) 15 The Subject Land is affected by Section 173 Agreement No. AL599252 (the Section 173 Agreement). A copy of the certificates of title and the Section 173 Agreement are contained in Tabs 5 and 10 of the Hearing Book. 16 The Subject Land has a frontage to Bass Highway of approximately 285 metres. It runs eastward from the Bass Highway for some 2177 metres. Its north-south depth generally varies between 490 metres and 1137 metres. The Subject Land is 156 hectares in size. 17 The western part of the Subject Land sits within the coastal plain between Western Port Bay and the Strzelecki Ranges to the east. It is gently undulating with an ephemeral tributary, MW3840, to Deep Creek located within part of it. The eastern part of the land is more undulating and forms part of the foothills to the Strzelecki Ranges. The site’s elevation ranges from approximately 120 m AHD on the ridge in the east of the site, down to less than 10 m AHD at the western end of the Deep Creek tributary. 18 The Subject Land includes three small lots fronting the Bass Highway. Each of these have a dwelling and associated shedding located on them. 19 Prior to sand extraction commencing, the Subject Land was historically used for grazing activities. Pasture grasses were the predominant vegetation, with native vegetation located in areas of the eastern part of the land. 20 Apart from 2 dwellings located near the south west corner of the property near the Bass Highway, the proposed extraction site is well buffered from all surrounding properties not owned by the applicant.
