1.2 DEFINITION OF SYMBOLS AND TERMS
Throughout this section the following terms and abbreviations are used to denote equipment and services.
CCTV Closed Circuit Television EFTPOS Electronic Funds Transfer at Point of Sales FTA Free to Air kVA Kilovolt Ampere LED Light Emitting Diode LPG Liquified Petroleum Gas MATV Master Antenna Television NBN National Broadband Network TMV Thermostatic Mixing Valve
2.0 INFRASTRUCTURE
2.1 POWER SUPPLY
There are three wood poles on the site belonging to Tasnetworks and carrying high voltage along the South Western boundary. The pole closest to the existing accommodation block (414847) has a relatively new pole mounted transformer (T72 117) which although has lost its markings, is about the size of a 200kVA unit or 260 Amps per phase.
CES196066R-A1-HA01 Great Lake Hotel Redevelopment May 2019 Miena for Johns Group (1) Building Services Condition Report
An overhead supply in ABC or insulated conductor runs to a private pole (414848) which is in good condition. At this point there are some pole mounted service fuses to protect an underground 3 phase supply to a main switchboard on the side of the shop. This is supply authority metered on one tariff and is rated at less than 40 Amps per phase.
Also from the private pole, 4 single insulated conductors are strung overhead across the internal carpark to the wall of the hotel on the second level. These then pass down the wall cavity to the Hotel main switchboard below. The switchboard is metered on three tariffs – light and power (3 phase 100 Amp), Hot water (1 phase 80 Amp) and off peak (1 phase 80? Amp).
There is a separate switch for the fire pump (1 phase 35 Amp). A non-compliance is that there are 2 points of supply for the one title but could be argued on physical separation of the Shop and Hotel that this is acceptable. Will affect future development of the site and would require a new site main switchboard.
The Hotel has no back-up generator or point of connection.
The Shop has a back-up generator but it is owned by the Lessee.
It was reported that whilst power outages are not that prevalent, they can last for extended periods. This needs to be balanced against a potential cost of $60k or so to install a back-up generator to the Hotel.
CES196066R-A1-HA01 Great Lake Hotel Redevelopment May 2019 Miena for Johns Group (2) Building Services Condition Report
2.2 COPPER TELEPHONE SERVICES
Telstra underground cables and pits exist in the road verge of the Marlborough Highway. There appears to be separate copper cables run underground to the Hotel and Shop, these could not be located but would be 10 pair based on past usage.
The services to the Shop are no longer utilised but there is a public phone box which remains operational. The services to the Hotel are only utilised for FAX and telephone landline.
2.3 NBN
Both the Hotel and Shop have independent wireless broadband services with a direct line of site to the local tower. Each has a dish on the roof.
The Hotel has two service providers over the link – one for private owners use and one for EFTPOS, KENO and Hotel Wi-Fi.
The Wi-Fi service provided free to customers has no reported limitations – the only issue is that in case of power failure at the tower site, the NBN service is lost after approximately 3 hours.
CES196066R-A1-HA01 Great Lake Hotel Redevelopment May 2019 Miena for Johns Group (3) Building Services Condition Report
2.4 LPG
There is a substantial bullet on site to provide LPG to site services. At this time that is confined to kitchen equipment (2 deep fryers, griddle and 8 burner cook top) and space heating in the second level private residence. Previous connections to gas dryers have been capped off.
2.5 FIRE DETECTION AND PROTECTION
Fire detection is limited to stand alone smoke alarms in bedrooms. There is no AS 1670.1 detection system or occupant warning system in any of the buildings.
Fire protection is afforded by a series of 4 external fire hose reels throughout the Hotel and a non-compliant hydrant adjacent the fire water tank. There are no facilities to the Shop and camping grounds.
CES196066R-A1-HA01 Great Lake Hotel Redevelopment May 2019 Miena for Johns Group (4) Building Services Condition Report
There is an above ground PVC water tank of some 20,000l capacity against the cabin accommodation block. Adjacent to this is an electric fire pump and an 80 mm stand pipe hydrant connected to the tank. From the tank to the pump is a PVC pipe that is subject to fire or physical damage (along with the tank if there was a fire in the accommodation block). From the pump, fire water is piped underground in PVC pipe to 4 external fire hose reels. These fire hose reels have been maintained but some of the enclosures require replacement. Adequate coverage from the FHR would need to be checked for compliance.
The procedure in case of fire is to go to the tank, open the valve and manually start the pump. In case of loss of power supply and without a means of advance warning via a smoke detection system, lack of any automation or provision of alarms in case of loss of water supply in the tank make the system a risk that would need to be assessed by a Fire Engineer.
There is no fire sprinkler system.
CES196066R-A1-HA01 Great Lake Hotel Redevelopment May 2019 Miena for Johns Group (5) Building Services Condition Report
2.6 WATER SUPPLY
Fresh water supply is from an on-site bore that fills an underground tank via float control on the East of the Hotel. This water is then pumped to service the Hotel and Shop.
The Shop has an external tank that gravity feeds the Shop in times of loss of power supply. Pumping to a high level tank to then gravity feed all water outlets may assist in times of power failure.
2.7 SEWER
All sewer connections including the Shop are gravity fed to a septic tank system on the East of the Hotel. The grey water is separately collected in an adjacent tank and then pumped to a primary and secondary settling pond to the West of the site.
CES196066R-A1-HA01 Great Lake Hotel Redevelopment May 2019 Miena for Johns Group (6) Building Services Condition Report
Advice was that the septic tank required pumping out every 6 to 9 months.
During Winter the public toilet adjacent the Shop is subject to freezing and requires management. The grey water pump system has been replaced recently.
2.8 STORM WATER
There is evidence that downpipes from the building also run into a second underground tank which is then utilised for site irrigation via a separate pump.
3.0 BUILDING SERVICES
3.1 GENERAL
We understand the building was constructed in 1984 and taken over by the present owner some 16 years ago. There are numerous non conformances obviously with current standards but they would only come into effect if substantial modifications were undertaken where we have noted – or else compliance with standards at the time of construction is assumed.
The owner has undertaken most maintenance of services required and has undertaken some upgrades to services such as replacement of bayonet lamps with compact fluorescent type, upgrade of grey water pump station, replacement of hot water cylinders as required, external flood lighting replacement with LED type, Freezer Room condenser upgrade.
CES196066R-A1-HA01 Great Lake Hotel Redevelopment May 2019 Miena for Johns Group (7) Building Services Condition Report
3.2 SWITCHBOARDS, SUBMAINS & CABLING
The main switchboard for the Hotel is located externally and is set up for three tariffs. Submains for light and power and hot water are extended to 5 panel boards (single phase) that service the accommodation wings.
All submain protection and subcircuit protection are circuit breakers but there are no RCD circuit breakers installed apart for the new sewer pump station.
4 of the panel boards are equipped with circuit breakers but only one subcircuit (fire pump) has RCD protection. One panel board is equipped with fuse cartridges with some circuit breaker inserts but no RCD protection.
The main switchboard for the Shop is located externally and is single tariff only. It is equipped with circuit breakers but only one is RCD protected – the recently installed air conditioner.
CES196066R-A1-HA01 Great Lake Hotel Redevelopment May 2019 Miena for Johns Group (8) Building Services Condition Report
3.3 INTERNAL LIGHTING
Hotel lighting control is from a central location BOH – straight switching and no dimming.
Luminaires date back to original construction and therefore are approaching end of life and several already have.
The original lighting would have consisted of surface mounted fluorescent battens plus surface mounted incandescent batten holders and recessed incandescent downlights.
Internally batten holders and recessed downlights have had the incandescent lamps replaced with compact fluorescent lamps. This has created a glare issue in the main.
Fluorescent battens need replacing as lamps will no longer be available and are corroded externally.
In accommodation areas there are fluorescent battens plus some incandescent wall lights – comments apply as above.
CES196066R-A1-HA01 Great Lake Hotel Redevelopment May 2019 Miena for Johns Group (9) Building Services Condition Report
3.4 EXTERNAL LIGHTING
Several building mounted flood lights have been replaced with LED type. Coverage at night is unknown but should be adequate to complement CCTV coverage. Covered walkway lighting to accommodation units consist of fluorescent battens that need maintenance plus incandescent batten holders that have no lamps.
There is no car park pole lighting as such, reliant on building mounted lighting.
Shop has some new fluorescent luminaires under driveway canopy but some original fittings remain. Similarly within Shop – surface mounted fluorescent fittings.
3.5 HEATING
Off peak power supplies feed into in slab floor heating in the Dining Rooms and Bar. These have been disconnected and no longer utilised in favour of wood heaters. Removal of this tariff should be considered.
Bedrooms are heated with wall mounted fan heaters. There is no heating in ensuites.
CES196066R-A1-HA01 Great Lake Hotel Redevelopment May 2019 Miena for Johns Group (10) Building Services Condition Report
Common areas are predominately heated with wood heaters.
Ancillary heating to the Shop is by a floor mounted LPG gas heater supplied from a dedicated bottle supply.
3.6 EMERGENCY & EXIT LIGHTING
There was no evident emergency lighting to any of the buildings including Shop and no emergency and exit light test stations to any switchboards.
There is one lit exit sign to the main entry and one to the rear entry only. Neither are operable on battery and have probably not had regular testing undertaken.
3.7 DATA & WI-FI
There is no communications rack on site as such, discrete Cat 5E links are used to interconnect NBN to shelf mounted switches and to EFTPOS, Room Booking system and the like.
CES196066R-A1-HA01 Great Lake Hotel Redevelopment May 2019 Miena for Johns Group (11) Building Services Condition Report
Similarly there are 3 Wi-Fi wireless access points within the accommodation areas to provide full coverage to the site.
3.8 ELECTRONIC SECURITY
The Hotel has a domestic type electronic intruder detection system only with limited motion detectors plus external and internal annunciators.
The Hotel has a 16 camera colour CCTV system with three monitors in BOH for monitoring.
The Shop has a 4 camera colour CCTV system with a single monitor.
There is no access control system.
3.9 MATV & FOXTEL
There are separate MATV systems to Shop and Hotel. In the Hotel there is a FTA distributed system to all bedrooms but not Foxtel.
CES196066R-A1-HA01 Great Lake Hotel Redevelopment May 2019 Miena for Johns Group (12) Building Services Condition Report
There are separate Foxtel (or equivalent) dishes to Shop and Hotel.
3.10 AIR CONDITIONING
The only unit located on site is within the Shop and is Lessees private property.
3.11 LAUNDRY EQUIPMENT
Two commercial electric washers and two commercial electric dryers in good condition.
3.12 HOT WATER SYSTEMS
There are 4 electric hot water cylinders servicing the site. They age between 2009 and 2011 so a replacement scheme has been ongoing.
CES196066R-A1-HA01 Great Lake Hotel Redevelopment May 2019 Miena for Johns Group (13) Building Services Condition Report
No evidence of TMV’s or tempering valves were located. No cylinders had drain trays with subsequent drainage to waste.
3.13 MECHANICAL EXHAUST
Most ensuites and amenities do not have mechanical exhaust and rely on natural ventilation via opening windows.
There are 6 wall mounted exhausts to the Dining and Bar areas that are individually controlled from BOH area.
CES196066R-A1-HA01 Great Lake Hotel Redevelopment May 2019 Miena for Johns Group (14) Building Services Condition Report
There are wall mounted exhausts to amenities in Bar area.
Kitchen hood is non-compliant as it has a horizontal section of canopy. The effectiveness of the fan is questionable as kitchen paper is evident in the drain tray of the hood. Testing of the fan performance and cleaning of system components upstream of filters would be recommended. Make up air is via opening window and door. Must be a major issue in Winter if no preheating is undertaken.
CES196066R-A1-HA01 Great Lake Hotel Redevelopment May 2019 Miena for Johns Group (15) Building Services Condition Report
3.14 BUILT UP COOLROOMS AND FREEZER ROOMS
There is a Kitchen Freezer, Kitchen Cold Room and Bottle Shop Cool Room on site. The Freezer is serviced by a condenser unit installed some 7 years ago. The Cold Room is serviced by a condenser unit dating back to original installation. Refrigeration gas is non-compliant. The Cool Room is serviced by a condenser unit dating back to original installation. Refrigeration gas is non-compliant.
If maintenance is continued, all units should be adequate for 5 to 10 years’ service.
All rooms are non-compliant with respect to lighting, lighting control, emergency lighting, escape facilities, monitoring and alarms.

Alterations and additions to an existing building at 3096 Malborough Road, Miena requires demonstrated compliance with Building Amendment (Bushfire-Prone Areas) Regulations 2014, and the Determination, Director of Building Control – Requirements for Building in Bushfire-Prone Areas, version 2.1 29th August 2017, the site is located in a bushfire prone area. The Bushfire attack level has been determined as ‘BAL- 12.5’, provisions for property access and water supplies for firefighting are detailed in this report and on the Bushfire Hazard Management Plan (BHMP).
3.0 Introduction
This bushfire hazard report has been completed to form part of supporting documentation for a building permit application for the proposed development. The proposed development site has been identified as being in a bushfire prone area. A site-specific bushfire hazard management plan has been provided for compliance purposes.
Bushfire Hazard Report – 3096 Malborough Road, Miena. September 2019. GES00017v1.0 3 of 18
4.0 Proposal
The proposal is for alterations and additions to an existing building at 3096 Malborough Road, Miena (appendix B). Construction standards for buildings, property access, water supplies for firefighting and hazard management areas will be required (as appropriate) to meet the standards outlined in the ‘Director’s Determination – Requirements for Building in Bushfire-Prone Areas’ and ‘Australian Standard 3959-2018 Construction of Buildings in Bushfire-prone Areas.
5.0 Bushfire Attack Level (BAL) Assessment
5.1 Methods
The Bushfire attack level has been determined through the application of section 2 of AS3959-2018 ‘Simplified Procedure’ of AS3959-2018. Vegetation has been classified using a combination of onsite observations and remotely sensed data to be consistent with table 2.3 of AS359-2018. Slope and distances have been determined by infield measurement and/or the use of remotely sensed data (aerial/satellite photography, GIS layers from various sources) analysed with proprietary software systems. Where appropriate vegetation will be classified as low threat.
5.2 Site Description
The proposal is located at 3096 Malborough Road, Miena, in the municipality of Central Highlands and is zoned Local Business under the Central Highlands Interim Planning Scheme 2015. Access to the lot will be by an existing crossover from Malborough Road, a state-maintained road. The lot is ~ 2.9 ha is irregular in shape and is located approximately 1.8km north west of Mackersay Head (Figure 1). Adjacent lands surrounding the lot are zoned rural resource. At a landscape scale the lot occurs on the south western edge of Great Lake in a rural setting characterised by predominantly native forest vegetation. The lot has gentle slopes with a northerly aspect and is unlikely to influence fire behaviour.
Vegetation surrounding the lot was assessed (Table 1) and described as ‘Grassland and Forest’ (as per AS3959-2018). The classified vegetation potentially having the greatest impact on the site occurs on every azimuth of the site (Figure 2). The vegetation classification system as defined in AS 3959-2018 Table 2.3 and Figure 2.3 (A to G) has been used to determine vegetation types within 100 metres of the site (Table 1).

6.0 Results
The bushfire attack level for the site has been determined as BAL-12.5. While the risk is considered to be low, there is a risk of ember attack and a likelihood of low levels of radiant heat impacting the site. The construction elements are expected to be exposed to a heat flux not greater than 12.5 kW/m2. The northern azimuth requires a minimum separation distance from the bushfire prone vegetation of 32 metres to achieve a BAL of 12.5. This will be a combination of 7 metres inside the title boundary and the adjoining excluded land.
6.1 Property Access There is existing access to the site, in this circumstance there is no further requirement for the design or constructions standards for property access.
6.2 Water supplies for fire fighting Static water supplies and associated infrastructure for firefighting purposes will be provided in accordance with table 4.3B of the Determination, Director of Building Control – Requirements for Building in Bushfire- Prone Areas, version 2.1 29th August 2017. The following elements of table 4.3B as noted above will be required to meet compliance; A Distance between building area to be protected and water supply B Static water supplies C Fittings, Pipework and accessories (including tank and stands) D Signage for static water supply connections E Hardstand
Bushfire Hazard Report – 3096 Malborough Road, Miena. September 2019. GES00017v1.0 7 of 18
6.3 Hazard Management Area. The Bushfire Attack Level for this site is BAL-12.5. A hazard management area contained within the title boundaries will need to be established to achieve this outcome. Table 1 above shows the minimum separation distances (hazard management area width) for each azimuth of the site that will result in a bushfire attack level of BAL-12.5. These are the minimum separation distance between the site (house) and the bushfire prone vegetation.
The bushfire attack level for the proposed site is BAL-12.5. There is a risk of ember attack, particularly from wind borne embers from forest vegetation types in the local area. The hazard management area should have sufficient fuel removed such that the propagation or carriage of fire is significantly impeded.
Hazard management areas for alterations or additions to buildings must meet the following requirements: (a) Be located on the lot so as to be provided with an HMA which: (i) Has the separation distances required for the BAL assessed for the construction of the existing building; or (ii) In the case of a building without an existing BAL assessment, is no smaller than the separation distances required for BAL 29; and (b) Have an HMA established in accordance with a certified bushfire hazard management plan.
The attached bushfire hazard management plan is certified and provides for the above conditions to be met. Separation distances are given and will provide for a bushfire attack level of BAL-12.5 at the site.

8.0 Guidance
The defendable space (hazard management area) around a building is critical for providing occupants and/or fire fighters with safe access to the building in order that fire fighting activities may be under taken. The larger the defendable space, the safer it will be for those defending the structure. Some desirable characteristics of a hazard management area are:
• The area directly adjacent to the building has a significant amount of flammable material removed such that there is little to no material available to burn around the building; • Includes non flammable areas such as paths, driveways, short cropped lawns; • Establishment of orchards, vegetable gardens, dams or waste water effluent disposal areas on the fire prone side of the building; • Creating wind breaks and radiation shields such as non combustible fences and low flammability hedges; • Removing fire hazards such as wood piles, rubbish heaps and stored fuels; • Creating and maintaining vertical as well as horizontal separation between ground fuels and tree canopies by pruning; • It is not necessary to remove all vegetation from the defendable space, trees can provide protection from wind borne embers and radiant heat in some circumstances.

11.0 Limitations Statement
This Bushfire Hazard Report has been prepared in accordance with the scope of services between Geo- Environmental Solutions Pty. Ltd. (GES) and the applicant named in section 2. To the best of GES's knowledge, the information presented herein represents the Client's requirements at the time of printing of the Report. However, the passage of time, manifestation of latent conditions or impacts of future events may result in findings differing from that described in this Report. In preparing this Report, GES has relied upon data, surveys, analyses, designs, plans and other information provided by the Client and other individuals and organisations referenced herein. Except as otherwise stated in this Report, GES has not verified the accuracy or completeness of such data, surveys, analyses, designs, plans and other information. The scope of this study does not allow for the review of every possible bushfire hazard condition and does not provide a guarantee that no loss of property or life will occur as a result of bushfire. As stated in AS3959-2018 “It should be borne in mind that the measures contained in this Standard cannot guarantee that a building will survive a bushfire event on every occasion. This is substantially due to the degree of vegetation management, the unpredictable nature and behaviour of fire, and extreme weather conditions”. In addition, no responsibility is taken for any loss which is a result of actions contrary to AS3959-2018 or the Tasmanian Planning Commission Bushfire code. This report does not purport to provide legal advice. Readers of the report should engage professional legal practitioners for this purpose as required. No responsibility is accepted for use of any part of this report in any other context or for any other purpose by third party.

Introduction
Client: Johns Group Tasmania Date of inspection: 17/4/2019 Location: Great Lake Hotel - 3096 Marlborough Road, Miena 39Land description: Approx. 2.9ha Building type: Existing buildings Investigation: GeoProbe 540UD Inspected by: JP Cumming B.Agr.Sc (hons) PhD CPSS GAICD and G. McDonald
Background information
Map: Mineral Resources Tasmania SE Tasmania 1:250000 Rock type: Jurassic Dolerite Soil depth: Approx. 1.80m+. Planning overlays: None identified in wastewater area Local meteorology: Annual rainfall approx. 800mm Local services: Tank water and on-site wastewater required
Site conditions
Slope and aspect: Approx. 4% slope to the East Site drainage: Moderate to imperfect drainage Vegetation: Mixed bush species Weather conditions: Cloudy, approx. <10mm of rain received in preceding 7 days. Ground surface: Slightly moist surface conditions, very rocky
Investigation
A number of auger holes were completed to identify the distribution of, and variation in soil materials onsite. A representative auger hole drilled at the approximate location indicated on the site plan was chosen for testing and classification according to AS1547-2012 (see profile summary).

Profile Summary
Hole 1 Horizon Description Depth (m)
0.00 – 0.25 A1 Dark Reddish Brown Clayey SAND (SC), peaty loam, weak polyhedral structure, slightly moist, loose consistency, abundant roots, ~15% clay, rocks and cobbles, gradual boundary to 0.25 – 1.8+ B1 Brown and Strong Brown Sandy Gravelly CLAY (CL), strong sub- angular blocky structure, moist, stiff consistency, medium plasticity, common rocks and cobbles, lower boundary undefined
Soil Profile Notes The soils onsite consist of clayey sands overlying clay loam subsoils which are developing on a combination of dolerite colluvium and fractured dolerite bedrock. The significant amount of gravels throughout the profile will improve soil permeability for onsite wastewater disposal.
Wastewater Classification & Recommendations
According to AS1547-2012 (on-site waste-water management) the natural soil is classified as Clay Loam (Category 4) with a Design Irrigation Rate (DIR) of 3.5mm/day.
The proposal is to upgrade the wastewater system of the hotel and restaurant and decommission the existing lagoon system. The hotel and restaurant will be serviced by a commercial sized AWTS unit and a grease trap connected to the kitchen.
Accommodation units The existing 15x one bedroom accommodation units each have a calculated maximum wastewater loading of 240L/day. This is based on tank water supply and a maximum occupancy of 2 people per unit (120L/day/person). For further detail please see table 1.
Restaurant and Cafe The proposed restaurant will have a peak wastewater loading of 1000L/day. This based on a maximum of 100 patrons/day for the restaurant at 10L/person/day. For further detail please see table 1.

Geo-Environmental Solutions Pty Ltd – Site Assessment 3096 Marlborough Road
Managers residence The existing dwelling has a calculated maximum wastewater loading of 480L/day. This is based on tank water supply and a maximum occupancy of 4 people (120L/ person/day) For further detail please see table 1.
Table. 1 Wastewater and BOD loadings for accommodation units, restaurant and managers residence
People/day Loading Total loading BOD BOD Total L/person/day (L/unit/day) (grams/person/ (grams/day) day) Units 30 120 3600 80 2400
Restaurant 100 10 1000 10 1000
Managers 4 120 480 80 320 residence Total 134 5080 3070
Given a total wastewater loading of 5080L/day, and a DIR of 3.5mm/day, then 1400m2 of surface irrigation into the native bush is required to accommodate the expected flows for the accommodation units, restaurant and managers residence. Due to the low slope angle a cut- off diversion drain will not be required. The area excluded from traffic or any future building works and a 100% reserve area should be set aside for future wastewater requirements. For further detail please refer to the attached plan and Trench summary reports.
The following setback distances are required to comply with the Building Act 2016:
Upslope or level buildings: 3m
Downslope buildings: 2.5m
Upslope or level boundaries: 1.5m
Downslope boundaries: 2.5m
Downslope surface water: 100m
Compliance with Building Act 2016 Guidelines for On-site Wastewater Management Systems is outlined in the attached table.

AS1547:2012 – Loading Certificate – AWTS Design
This loading certificate sets out the design criteria and the limitations associated with use of the system.
Site Address: Great Lake Hotel – 3096 Marlborough Road, Miena
System Capacity: 5080L/day
Summary of Design Criteria
DIR: 3.5mm/day.
Irrigation area: 1400m2
Reserve area location /use: assigned – more than 100% available
Water saving features fitted: Standard fixtures
Signage: Suitable warning signs to be displayed around the disposal area indicating that reclaimed water is being used i.e. “Recycled Water, Avoid Contact, Do Not Drink”
Allowable variation from design flows: 1 event @ 200% daily loading per quarter
Typical loading change consequences: Expected to be minimal due to use of AWTS and large land area
Overloading consequences: Continued overloading may cause hydraulic failure of the irrigation area and require upgrading/extension of the area. Risk considered acceptable due to monitoring through quarterly maintenance reports.
Underloading consequences: Lower than expected flows will have minimal consequences on system operation unless the house has long periods of non occupation. Under such circumstances additional maintenance of the system may be required. Long term under loading of the system may also result in vegetation die off in the irrigation areas and additional watering may be required. Risk considered acceptable due to monitoring through quarterly maintenance reports.
Lack of maintenance / monitoring consequences: Issues of underloading/overloading and condition of the irrigation area require monitoring and maintenance, if not completed system failure may result in unacceptable health and environmental risks. Monitoring and regulation by the permit authority required to ensure compliance.
Other considerations: Owners/occupiers must be made aware of the operational requirements and limitations of the system by the installer/maintenance contractor.

Design specifications: 1. Manufacturer’s recommendations for spacing of irrigation lines and sprinklers should be followed (i.e. wobbler® 5.56 mm sprinklers) with a longitudinal spacing of approx 5m centers. 2. Typical sprinkler flow rates are 0.3-0.8L/sec per 5.56 mm emitter dependant pressure. 3. Sprinklers to be placed on secure staked risers with sufficient height to clear undergrowth such as grass and sedges 4. A flush line must be installed at the lowest point/bottom of the irrigation area with a return valve for flushing back into the treatment chamber of the system (not into the primary chamber as it may affect the performance of the microbial community) or to a dedicated absorption trench. 5. The minimum irrigation pumping capacity should be a 12m head or 120 kpa measured at the highest point of the irrigation area. 6. Pressure check valves to be used on steep sites on each sprinkler line to ensure even distribution

EXECUTIVE SUMMARY This report presents the findings from Preliminary Site Investigation (PSI) undertaken by Geo- Environmental Solutions Pty. Ltd. (GES) at Great Lakes Hotel, 3096 Marlborough Highway, Miena - hereby referred to as ‘The Site’. GES was engaged by The Johns Group P/L to conduct this investigation. This report is a requirement for the potential sale of land is it has been prepared by a suitably qualified and experience practitioner in accordance with procedures and practices detailed in NEPM (2013) guidelines and key regulations and policies. The objective of the PSI was to determine the following for the potential sale/purchase of land: • Conduct a desktop assessment the suitability of the site for the intended use; • Confirm if contamination is likely and the likely extent of the contamination at the site; • Complete a preliminary assessment of site wastewater infrastructure; • Consider impact on human health and the environment in a conceptual site model (CSM); • Provide recommendations on what measures may need to be put in place to address any potential data gaps and to further assess contamination remediation and/or management (if required). The scope of works of this PSI was to: • Conduct a desktop assessment, site history including WorkSafe Tasmanian Search, Environmental Protection Authority (EPA) Tasmania and The LIST data base search. • Site visit; photographs of site conditions, limited sample collection. • Limited soil testing; one soil sample was collected from the effluent pond wall. The sample was analysed for Total Recoverable Hydrocarbons (TRH), Benzene Toluene Ethylbenzene Xylene Naphthalene (BTEXN), Polynuclear Aromatic Hydrocarbons (PAHs);a suite of 15 Metals plus OC/OP Pesticides. • The analytical results against were compared against NEPM ASC (2013) guidelines as well as other relevant guidelines for assessing hydrocarbon vapour and soil dermal contact risks; and • Present the findings of the site investigation, conduct a risk assessment and develop a conceptual site model (CSM) plus present future investigation recommendations. • Undertake preliminary assessment of site wastewater and bore water supply infrastructure. The following conclusions were made from the desktop assessment: • The site is zoned Local Business on the eastern half of the site and Rural Resource on the western half of the site under the Central Highlands Interim Planning Scheme of 2015 • WorkSafe Tasmania confirmed the following information for the site; it has hosted fuel storage and sales since the mid-1980 and has three underground storage tanks of diesel, unleaded petrol and leaded petrol (super). The site has also held LPG on site for sales and cooking purposes. This investigation is not concerned with the LPG storage as contamination from this is unlikely. • The site is underlain with Jurassic Dolerite. The site is approximately 1060m above sea level. Groundwater is inferred to be directed towards the east to Swan Bay on Great Lake with the same aspect as the surface topography. This is the closest ecological receptor. The edge of the lake is 450m east from the UPSS infrastructure. • The historical aerial photographs confirm the following: There are numerous buildings on site associated with the hotel activities. The two sewage settling ponds have been onsite since the hotel facilities were constructed. There appear to be two informal rubbish dumps on the site. There was a wildfire in that area summer of 2019, as seen in the 2019 aerial photograph. • GES is aware of the following report for the site: Site Services Due Diligence Report for Johns Group Great Lake Hotel Redevelopment by Coordinated Engineering Services (CES). CES confirmed that the site has hosted a commercial shop front and hotel accommodation since 1984. • The Environmental Protection Authority (EPA) Tasmania is aware that the site has three active registered underground petroleum storage systems with a total volume of 40,000L which is considered as a potentially contaminating activity. • There appear to be no monitoring records for the fuel infrastructure, and it also appears that no formal loss monitoring and reporting (SIRA) has been completed; • The shop and refuelling area has no spill containment or loss control in place with only an open stormwater drain present, therefore any surface spills during operations since the 1980’s are likely to have impacted soil and possibly groundwater in the area;
Geo Environmental Solutions – GES Page ii Preliminary Site Investigation. Great Lakes Hotel, 3096 Marlborough Highway, Miena. June 2019
• Conceptual Site Model o As determined in this desktop assessment, areas of potential concern (AOPC) on site relate to the activities relating to fuel storage and sales; including: ▪ Back-up generator operated by the shop – diesel powered unknown but assumed; ▪ UPSS infrastructure adjacent to the shop – diesel, ULP and Super petrol stored in underground tanks plus, 2 bowsers 1 x single electric pump and 1 x duel electric pump; and ▪ Informal rubbish dumps – house-hold waste in two localised areas ▪ The effluent ponds o The following contaminants of potential concern (COPC) associated with underground fuel storage, dispensing infrastructure and other activities have been identified on site: ▪ Total Petroleum/Recoverable Hydrocarbons (TPH/TRH); ▪ Mono Aromatic hydrocarbons: Benzene, Toluene, Ethylbenzene, Xylene (BTEX); ▪ Polycyclic Aromatic Hydrocarbons (PAH) including Benzo(a)pyrene (B(a)p) and ▪ Lead; plus ▪ Heavy Metals and hydrocarbons from informal waste dumps and accumulation in sewerage sludge.
The following conclusions have been made from the assessment of the wastewater and bore water infrastructure: • Np grease trap is installed for the commercial kitchen on site • The two effluent ponds are unlined, in poor condition, with an open outlet to the ground surface • The effluent ponds are considered to be non-compliant with health and environmental standards and will require decommissioning and replacement with a suitable new system as part of any site redevelopment • Soil testing shows the pond walls to have low level heavy metal contamination (level 2 according to EPA IB105) which will require appropriate management • The bore water supply appears to be in a dolerite aquifer with low to moderate yield, and preliminary screening of water samples showed a positive to bacterial contamination • The bore system has inadequate storage, filtration, and treatment • The bore system requires more detailed investigation and testing, and will require upgrading of infrastructure as part of any site redevelopment
GES recommends the following: • An Environmental Site Assessment (ESA) should be completed to understand if the existing UPSS infrastructure has been compromised overtime. This must include invasive soil investigation in the vicinity of the underground storage tanks plus the area surrounding the generator where hydrocarbon containing fuels may have been spilt. Soil surrounding the informal waste dumps should also be tested. The ESA could be completed as part of any development application package for the site. • The bore water system should be testing for yield, plus draw down, and further tested for quality parameters including bacteria to determine if the effluent ponds, surface contamination from animals or other sources are impacting water quality.

2.6 Dangerous Goods Records (WorkSafe Tasmania)
Dangerous goods records for the site were provided by WorkSafe Tasmania on the 17 May 2019. Table 2 summarises the relevant documents and these documents in their entirety are provided in Appendix 3. Figure 6 is a site plan for the underground petroleum storage systems (UPSS) in October 2006 and Figure 7 is a site plan in May 1990. In summary the site has hosted fuel storage and has three underground storage tanks used for the storage of diesel, unleaded petrol and leaded petrol (super). site has also held LPG on site for sales and cooking purposes. This investigation is not concerned with the LPG storage as contamination from this is unlikely.

5 SOIL ECOLOGICAL IMPACT ASSESSMENT
5.1 NEPM ASC (2013) Guidelines
The following ecological investigation guidelines are to be addressed to assess acceptable levels of risk to terrestrial ecosystems: • NEPM ASC (2013) Ecological Investigation Levels (EIL’s) – have been developed for selected metal and organic substances. EIL’s depend on specific soil and physicochemical properties and land use scenarios and generally apply to the top two (2) metres of the soil profile (NEPM 2013); • NEPM ASC (2013) Ecological Screening Levels (ESL’s) – have been developed for selected petroleum hydrocarbon compounds and total petroleum hydrocarbon fractions. ESL’s broadly apply to coarse- and fine-grained soils and various land use scenarios within the top two (2) metres of the soil profile (NEPM ASC 2013).
Soil analytical results are compared against Ecological Screening Levels (ESL’s) and Ecological Investigation Levels (EIL’s) limits presented in Table 4. Table 4 Summary of Soil Investigation Limits Considered at the Site based in NEPM ASC (2013) Analytes Investigated Investigation Hydrocarbons Metals Levels (IL) TRH Benzo(a) pyrene Naphthalene Zn, Cu, Cr(III), DDT BTEX Lead (F1 to F4) (PAH) (PAH) Ni & As ESL’s Analysed Analysed Analysed EIL’s Analysed Analysed Analysed Not Analysed

6 SOIL HUMAN HEALTH DIRECT CONTACT ASSESSMENT
6.1 Guidelines
6.1.1 Land Use Classification The NEPM (2013) guidelines have been referenced to ensure that the correct land use and density category has been adopted for the site and the surrounding properties (where applicable). As per NEPM (2013) guidelines, the adopted land use class is dependent on the building density and the opportunity for soil access by site occupants (exposure to potentially impacted soil). Aspects needing to be considered include: • Whether the site is of sensitive land use such as a childcare centre, preschool, primary school or aged care facility in which case land use Class A is applicable; • The proportion of paved area to determine direct contact exposure risk and therefore classification as low or high density; and • Classification based on residential, recreational or commercial/industrial setting.
6.1.2 Adopted Land Use Classification The adopted land use class is presented in Table 7. Table 7 Summary of Land Use Spatial and Temporal Setting for Determining Exposure Risk Soil Location Land Use Pathway* Land Use Class Bores All Site Commercial workers ALL D * Pathways: DC – Dermal Contact – HSL Trench Worker Guidelines (CRC CARE 2013) DI – Dust Inhalation - HIL Guidelines (NEPM ASC 2013) SI – Soil Ingestion - HIL Guidelines (NEPM ASC 2013) ALL – All of above

7 SOIL DISPOSAL ASSESSSMENT
7.1 Guidelines
Soil which is excavated from the site for landfill disposal is to be assessed against Information Bulletin 105 (IB105) for Classification and Management of Contaminated Soil for Disposal. The Environmental Protection Authority (EPA) uses 4 categories to classify contaminated soil as per Table 11: • (Level 1) Fill Material; • (Level 2) Low Level Contaminated Soil; • (Level 3) Contaminated Soil; and • (Level 4) Contaminated Soil.
Fixed numerical values are presented for soil concentrations and leachable fraction concentrations. Table 11 Summary of IB105 Classification Guidelines
7.2 Findings
The soil samples were compared against IB105 guidelines for soil disposal, see Table 12. There were no hydrocarbon detections. Some elevated metals were detected, and Chromium exceeded the Level 1 Material classification. It is likely that the chromium is naturally derived from either the dolerite or basalt found in the area.

8 Preliminary Assessment of Wastewater and Bore water Infrasturcture
8.1 Wastewater
The site is currently serviced by a basic septic tank/pump well system which sewerage to effluent treatment ponds located at the rear of the site (see plate 6 & 7). The system consists of two ponds, linked by a gravity line, and the ponds are both unlined, with effluent a bright green colour of low quality. The second treatment pond also has an outfall to the ground surface with no cover or absorption drain. The effluent pond area is also unfenced, and has open access for animals or public wandering around the site. The current system is considered non-compliant and would constitute a potential environmental and health hazard. It is also possible that the un-lined effluent ponds are leaching into the groundwater aquifer at the site, and potentially impacting the bore water supply. The presence of the ponds on site has also resulted in a planning attenuation overlay on the site which currently limits site development potential. It is assume that if the ponds are decommissioned and a new treatment system installed that the attenuation overlay will be removed.
It is recommended that the wastewater infrastructure be upgraded as part of any site development including the following: • Decommissioning of the existing effluent ponds • Review of the current primary pumping infrastructure and replacement or upgrading as required depending upon capacity requirements • Installation of appropriate grease trap for the hotel (min 3000L suggested to be required) • Design and installation of an appropriate treatment system for the site, with indications that a commercial aerated wastewater treatment system (AWTS) with irrigation of treated effluent on site would be suitable • Preliminary estimates suggest that a budget of approximately $100-150K should be allowed for decommissioning and replacement works

Plate 7 wastewater effluent ponds (note effluent colour and unlined pond)
8.2 Bore water
The site is currently serviced by a groundwater bore drilled to a depth of approximately 18m into the fractured dolerite underlying the site (see appendix 5). The standing water level is approximately 6m, although it is not known how this fluctuates with pumping draw down or seasonal rainfalls and recharge. The bore head has been excavated and a large concrete man hole installed for mounting of the pump, see plate 8 below. There does not appear to be any pre treatment or disinfection equipment installed for the bore water supply. The water quality appears to be good, with a clear colour and no odour. However, a presumptive sample for bacteria returned a positive result, suggesting some contamination is represent in the system. This could possibly be in the aquifer from effluent contamination or other sources. This could also be in the infrastructure on site or in the well head from animal droppings or other bacteria growing on delivery lines (water was tap sampled).
It is recommended that the bore water infrastructure be investigated upgraded as part of any site development including the following: • Pump testing of drawn down and yield • Thorough testing of the water quality from a number of points in the system including bacterial testing • The bore water and roof water supply be evaluated to ensure sustainable supply • An appropriate treatment system for metal removal and disinfection be designed and installed • Preliminary estimates suggest that a budget of approximately $25-50K should be allowed for upgrade works

9 CONCLUSIONS
9.1 Desktop Assessment
The following conclusions were made from the desktop assessment: • The site is zoned Local Business on the eastern half of the site and Rural Resource on the western half of the site under the Central Highlands Interim Planning Scheme of 2015 • WorkSafe Tasmania confirmed the following information for the site; it has hosted fuel storage and sales since the mid-1980 and has three underground storage tanks of diesel, unleaded petrol and leaded petrol (super). The site has also held LPG on site for sales and cooking purposes. This investigation is not concerned with the LPG storage as contamination from this is unlikely. • The site is underlain with Jurassic Dolerite. The site is approximately 1060m above sea level. Groundwater is inferred to be directed towards the east to Swan Bay on Great Lake with the same aspect as the surface topography. This is the closest ecological receptor. The edge of the lake is 450m east from the UPSS infrastructure. • The historical aerial photographs confirm the following: There are numerous buildings on site associated with the hotel activities. The two sewage settling ponds have been onsite since the hotel facilities were constructed. There appear to be two informal rubbish dumps on the site. There was a wildfire in that area summer of 2019, as seen in the 2019 aerial photograph. • GES is aware of the following report for the site: Site Services Due Diligence Report for Johns Group Great Lake Hotel Redevelopment by Coordinated Engineering Services (CES). CES confirmed that the site has hosted a commercial shop front and hotel accommodation since 1984. • The Environmental Protection Authority (EPA) Tasmania is aware that the site has three active registered underground petroleum storage systems with a total volume of 40,000L which is considered as a potentially contaminating activity. • There appear to be no monitoring records for the fuel infrastructure, and it also appears that no formal loss monitoring and reporting (SIRA) has been completed; • The shop and refuelling area has no spill containment or loss control in place with only an open stormwater drain present, therefore any surface spills during operations since the 1980’s are likely to have impacted soil and possibly groundwater in the area; • Conceptual Site Model o As determined in this desktop assessment, areas of potential concern (AOPC) on site relate to the activities relating to fuel storage and sales; including: ▪ Back-up generator operated by the shop – diesel powered unknown but assumed; ▪ UPSS infrastructure adjacent to the shop – diesel, ULP and Super petrol stored in underground tanks plus, 2 bowsers 1 x single electric pump and 1 x duel electric pump; and ▪ Informal rubbish dumps – house-hold waste in two localised areas ▪ The effluent ponds o The following contaminants of potential concern (COPC) associated with underground fuel storage, dispensing infrastructure and other activities have been identified on site: ▪ Total Petroleum/Recoverable Hydrocarbons (TPH/TRH); ▪ Mono Aromatic hydrocarbons: Benzene, Toluene, Ethylbenzene, Xylene (BTEX); ▪ Polycyclic Aromatic Hydrocarbons (PAH) including Benzo(a)pyrene (B(a)p) and ▪ Lead; plus ▪ Heavy Metals and hydrocarbons from informal waste dumps and accumulation in sewerage sludge.

The following conclusions have been made from the assessment of the wastewater and bore water infrastructure: • No grease trap is installed for the commercial kitchen on site • The two effluent ponds are unlined, in poor condition, with an open outlet to the ground surface • The effluent ponds are considered to be non-compliant with health and environmental standards and will require decommissioning and replacement with a suitable new system as part of any site redevelopment • Soil testing shows the pond walls to have low level heavy metal contamination (level 2 according to EPA IB105) which will require appropriate management • The bore water supply appears to be in a dolerite aquifer with low to moderate yield, and preliminary screening of water samples showed a positive to bacterial contamination • The bore system has inadequate storage, filtration, and treatment • The bore system requires more detailed investigation and testing, and will require upgrading of infrastructure as part of any site redevelopment
10 RECOMMENDATIONS GES recommends the following: • An Environmental Site Assessment (ESA) should be completed to understand if the existing UPSS infrastructure has been compromised overtime. This must include invasive soil investigation in the vicinity of the underground storage tanks plus the area surrounding the generator where hydrocarbon containing fuels may have been spilt. Soil surrounding the informal waste dumps should also be tested. The ESA could be completed as part of any development application package for the site. • The bore water system should be testing for yield, plus draw down, and further tested for quality parameters including bacteria to determine if the effluent ponds, surface contamination from animals or other sources are impacting water quality.
Yours faithfully,
Sarah Joyce BSc (Hons) Environmental Geologist

WASTEWATER LAGOONS – DECOMMISSIONING MANAGEMENT PLAN
2. EXECUTIVE SUMMARY This document has been prepared for the Johns Group in response to the request for a Decommissioning Management Plan (EMP) to be developed for the decommissioning of two existing wastewater lagoons at the Great Lake Hotel situated at 3090 Marlborough Highway Miena.
This plan primarily covers the management of environmental risks from the required works to decommission the lagoons. A complaint handling system is recommended for the management of any issues arising from the operations on the site.
A basic overview of commitments arising from this plan are as follows: • The contractors and site owners must eliminate the offsite movement of uncontrolled wastewater in stormwater or groundwater, by removing any remaining wastewater in the lagoons prior to excavation • The environmental consultant must ensure sludge in the lagoons is tested for classification according to EPA bulletin 105 and NEPM 2013 • Excess sludge in the lagoons not suitable to treatment and retention on site must be transported to an approved waste facility by a licensed contractor • The contractor must ensure all directions relating to site rehabilitation are followed including lime amendment of sludge, soil cover, and revegetation • A chain of custody must be kept by the contractor and endorsed by the environmental consultant for all wastewater and sludge leaving the site • The contractor must ensure all traffic management recommendations are followed to minimise odor and noise generation, and to ensure a safe working environment for all staff. • Maintain a complaints and enquiries register including but not limited to, any complaints regarding noise, odor, water management or potentially contaminating issues.
It should be noted that this document is only valid for the management of operations as currently understood by GES and any changes to site management, site infrastructure, or major changes to operations will require amendments to the plan and invalidate this document.

WASTEWATER LAGOONS – DECOMMISSIONING MANAGEMENT PLAN
3. SITE DESCRIPTION
3.1. Location The Great Lake Hotel is located at 3096 Marlborough Highway, Miena - hereby referred to as ‘The Site’. The site is zoned Local Business on the eastern half of the site and Rural Resource on the western half of the site under the Central Highlands Interim Planning Scheme of 2015.
The Site location is presented in Figure 1.
The Site
Figure 1 -site location
3.2. Background The Johns Group is intending to install a new wastewater system and decommission the existing wastewater infrastructure at the site, including the two wastewater lagoons on the property (see figure 2&3). The two lagoons have been in place for some time and the operation of the lagoons is not compliant with current environmental standards. The primary and secondary lagoons have an area of approximately 450m2 and 300m2 respectively, and an estimated total working volume of approximately 1ML. The lagoons have several environmental hazards that must be managed during the decommissioning process:
1. Wastewater in the lagoons will contain bacteria and other pathogens.
2. Sludge in the lagoons will be anaerobic, contain bacteria, pathogens, and potentially be contaminated with heavy metals and other substances.
3. Soil on the lagoon base and walls may also be potentially contaminated with heavy metals and other substances.

WASTEWATER LAGOONS – DECOMMISSIONING MANAGEMENT PLAN
4. ENVIRONMENTAL MANAGEMENT
A series of management impacts parameters have been assessed as part of this plan. They include management actions associated with the disposal of hard infrastructure in the lagoons, wastewater, residual sludge, and any contaminated soil that maybe encountered. A daily site checklist is attached as appendix 1.
4.1. Potential Environmental Impacts
4.1.1. Surface Water
There is potential for localized surface water contamination during the works. In particular uncontrolled release of wastewater or sludge from the lagoons must be managed.
Management Actions: • Access to be provided for pump truck in close proximity to the lagoons, a gravel pad or staging area maybe required for inclement weather • A SWMS to be prepared prior to all pumping operations and endorsed by all personnel on site and the environmental consultant • Any spare pumping equipment fittings and spare parts to be stored on racking or appropriate containers • Additional bunding and spill kits will be made available for the management of any localized fluid spills that may occur from the trucks
4.1.2. Groundwater
The groundwater at the site is unlikely to be affected by the works. Groundwater flow direction is expected to mirror the surface contours. If the soil underlying the site does become contaminated during works, then surface water could potentially leach contaminates into the groundwater, however if the plan is followed correctly this is unlikely to occur.
Management Action: • Effort should be taken to ensure minimal ground spillage of fluids during the operation of the site. • If there is a significant spill of fluids or other contaminants on the site immediate clean up action must be taken
4.1.3. Noise The nearby hotel has accommodation such that operators of machinery must be aware of potential nuisance noise. Noise generated by normal operations include traffic entering and exiting the site (i.e. truck brakes, starting of motors) and use of pumps, excavators and other machinery. During daily works, noise generation is considered unavoidable. Management Action: • Works will comply with all council regulations in regards to operating times. • Maintain a complaints register including any associated noise issues. Review the register on a regular basis in order to determine key characteristics and any requirement for further investigation and corrective actions
6
WASTEWATER LAGOONS – DECOMMISSIONING MANAGEMENT PLAN
4.1.4. Dust
During works at the site, particularly in the summer months, dust production is considered unavoidable. Where dust is produced there is some potential that it will contain contaminating materials.
Management Action: • There are unlikely to produce excessive amounts of dust, except in dry and windy conditions. • Where dust production is considered excessive, dust mitigation though watering would be required.
4.1.5. Odour
The dewatered lagoons have the potential to produce offensive odors from the anaerobic sludge and impact guests of the hotel.
Management Action: • The moisture status and odor of the sludge must be monitored upon dewatering and a bulk supply of lime available onsite for immediate stabilization of the sludge • The bulk supply of lime should be equivalent to a 1:2 ratio for mixing with the estimated sludge volume
4.1.6. Imported materials
Any imported fill material used in the management of the site will undergo validation sampling and be documented (it is not envisaged any imported fill will be required).
4.1.7. Wastewater
It is anticipated that a significant volume of the wastewater in the lagoons will evaporate following disconnection of the rising sewer main. Any wastewater remaining in the lagoons not able to be evaporated or discharged to the existing outfall will require removal from site and disposal in an approved wastewater treatment plant.
Management Action: • Residual wastewater to be disposed of at an approved wastewater plant by a licensed contractor (chain of custody to be kept)
4.1.8. Sludge
The lagoons will have a sludge layer that must be adequately managed. The sludge material has the potential to contain pathogens, and contaminates such as heavy metals.
Management Action: • Sludge in the lagoons must be tested by the environmental consultant in a NATA approved laboratory and classified according to Tasmanian biosolids guidelines, EPA IB105, and NEPM 2013 • Pending results sludge can be lime amended and incorporated into the soil on site
7
WASTEWATER LAGOONS – DECOMMISSIONING MANAGEMENT PLAN
• Any sludge not suitable for lime stabilization and reuse on site must be transported to an approved site by a licensed contractor • A chain of custody is to be kept for all testing, classification, and any disposal
4.1.9. Potentially contaminated soil
Soil forming the base and walls of the lagoon has potential to be contaminated, as a result the area must be adequately tested once sludge has been removed and prior to any spreading or removal of soil. Management Action: • Soil in the area of the lagoons must be tested by the environmental consultant in a NATA approved laboratory and classified according to and NEPM 2013 • If any soil dos not comply with the NEPM land use guidelines it must also be classified according to EPA IB105 and if off site disposal is required the appropriate approvals sought from EPA Tasmania (regulation 12) • Any removal or transport of contaminated soil must be undertaken by a licensed contractor to an approved facility and chain of custody to be kept
5. COMPLAINTS HANDLING SYSTEM A complaints handling system is recommended for the management of any issues arising from the operations of the site.
5.1. Objectives To ensure effective communication between nearby commercial occupants, residents and Site Management; by recording any complaints and responding directly to the complainant until the source of the incident is verified and resolved as far as is practicable.
5.2. Management Strategy
5.2.1. General To effectively manage community health, safety and environment concerns, the contractor will implement a complaints handling system. Complaints and enquires will be recorded in a complaints and enquiries register. The register will record the date, nature, and resolution of any action from a complaint.
Within two working days of a complaint being made, the complaint will be recorded on the complaints and enquiries register, investigated by the Operations Manager and a response sent to the complainant if necessary. Actions will then be taken to resolve the point of conflict.

RE: Great Lake Hotel – Proposed Water Treatment System
Mark, following our discussions regarding the water treatment system at the property I can provide the following additional information.
I have held discussions around the required specifications of the system with Nigel Vincent from water solutions Tasmania. A copy of the water quality results is attached, which indicates that the water quality is generally good and only requires filtration, minor pH correction and disinfection. As a result, he has provided the following information regarding the recommended filtration and treatment. • pH correction – a pH neutralising system is recommended to minimise copper corrosion (eg two NTS4000 cylinders in series) • General filtration – a general twin filter arrangement would be recommended to remove fine suspended sediment and organic material which can affect taste and odour (eg EM2 series) • Disinfection – to remove bacteria a UV filter is recommended to ensure adequate health standards (eg puretec radfire RI series commercial filters) • The filtration and disinfection will require fine tuning according to the flow rates and pumping arrangement as detailed below • A pump system will be required to deliver clean potable water to the building with a maximum estimated flow rate requirement (From Aldanmark) of 5.8L/Sec or approximately 350lpm. • To accommodate the peak flow rate a series of variable speed pumps are recommended, and a system such a DAB Esybox 3 pump arrangement capable of 360lpm would be suitable
I have attached copies of the water test results and the product information to this letter and I would nominate Water Solutions Tasmania as the preferred subcontractor.

The analytical procedures used by the Environmental Division have been developed from established internationally recognized procedures such as those published by the USEPA, APHA, AS and NEPM. In house developed procedures are employed in the absence of documented standards or by client request. Where moisture determination has been performed, results are reported on a dry weight basis. Where a reported less than (<) result is higher than the LOR, this may be due to primary sample extract/digestate dilution and/or insufficient sample for analysis.
Where the LOR of a reported result differs from standard LOR, this may be due to high moisture content, insufficient sample (reduced weight employed) or matrix interference.
When sampling time information is not provided by the client, sampling dates are shown without a time component. In these instances, the time component has been assumed by the laboratory for processing purposes. Where a result is required to meet compliance limits the associated uncertainty must be considered. Refer to the ALS Contact for details.
Key : CAS Number = CAS registry number from database maintained by Chemical Abstracts Services. The Chemical Abstracts Service is a division of the American Chemical Society. LOR = Limit of reporting ^ = This result is computed from individual analyte detections at or above the level of reporting ø = ALS is not NATA accredited for these tests. ~ = Indicates an estimated value. l EA010-P: Electrical Conductivity @ 25°C was analysed by manual method (EA010). l E.Coli & FC (MM696) is conducted by ALS Scoresby NATA accreditation no. 992, site no. 989. NATA accreditation does not cover performance of this method. l TC & E.Coli (MM698) is conducted by ALS Scoresby NATA accreditation no. 992, site no. 989. NATA accreditation does not cover performance of this method. l ED037-P: Poor duplicate precision observed carbonate alkalinity for sample #1. Insufficient sample remains to confirm results. l Ionic balances were calculated using: major anions - chloride, alkalinity and sulfate; and major cations - calcium, magnesium, potassium and sodium. l ED045G: The presence of thiocyanate can positively contribute to the chloride result, thereby may bias results higher than expected. Results should be scrutinised accordingly. l EA016: Calculated TDS is determined from Electrical conductivity using a conversion factor of 0.65. l HPC @ 22C and 36C (MM524) is conducted by ALS Scoresby NATA accreditation no. 992, site no. 989. l E.coli & Total Coliforms by MPN (MM514) is conducted by ALS Scoresby NATA accreditation no. 992, site no. 989. l Sodium Adsorption Ratio (where reported): Where results for Na, Ca or Mg are Sub-Matrix: WATER Client sample ID S Tank N Tank Bore ------(Matrix: WATER) Client sampling date / time 29-Jul-2019 00:00 29-Jul-2019 00:00 29-Jul-2019 00:00 ------Compound CAS Number LOR Unit EM1912087-001 EM1912087-002 EM1912087-003 ------Result Result Result ------EA005P: pH by PC Titrator pH Value ---- 0.01 pH Unit 6.69 6.43 7.12 ------EA010P: Conductivity by PC Titrator Electrical Conductivity @ 25°C ---- 1 µS/cm 49 47 67 ------EA016: Calculated TDS (from Electrical Conductivity) Total Dissolved Solids (Calc.) ---- 1 mg/L 32 30 44 ------EA045: Turbidity Turbidity ---- 0.1 NTU ---- 2.2 3.9 ------ED037P: Alkalinity by PC Titrator Hydroxide Alkalinity as CaCO3 DMO-210-001 1 mg/L <1 <1 <1 ------Carbonate Alkalinity as CaCO3 3812-32-6 1 mg/L <1 <1 <1 ------Bicarbonate Alkalinity as CaCO3 71-52-3 1 mg/L 12 11 25 ------Total Alkalinity as CaCO3 ---- 1 mg/L 12 11 25 ------ED041G: Sulfate (Turbidimetric) as SO4 2- by DA Sulfate as SO4 - Turbidimetric 14808-79-8 1 mg/L <1 <1 2 ------ED045G: Chloride by Discrete Analyser Chloride 16887-00-6 1 mg/L 7 8 6 ------ED093F: Dissolved Major Cations Calcium 7440-70-2 1 mg/L 2 3 5 ------Magnesium 7439-95-4 1 mg/L 1 1 2 ------Sodium 7440-23-5 1 mg/L 3 3 3 ------Potassium 7440-09-7 1 mg/L <1 <1 <1 ------EG020T: Total Metals by ICP-MS Aluminium 7429-90-5 0.01 mg/L 0.11 0.14 0.12 ------Antimony 7440-36-0 0.001 mg/L <0.001 <0.001 <0.001 ------Arsenic 7440-38-2 0.001 mg/L <0.001 <0.001 <0.001 ------Barium 7440-39-3 0.001 mg/L 0.001 0.002 0.002 ------Cadmium 7440-43-9 0.0001 mg/L <0.0001 <0.0001 <0.0001 ------Chromium 7440-47-3 0.001 mg/L <0.001 <0.001 <0.001 ------Copper 7440-50-8 0.001 mg/L 0.001 <0.001 0.002 ------Nickel 7440-02-0 0.001 mg/L <0.001 <0.001 <0.001 ------Lead 7439-92-1 0.001 mg/L <0.001 <0.001 <0.001 ------Zinc 7440-66-6 0.005 mg/L 0.017 0.015 0.007 ------Manganese 7439-96-5 0.001 mg/L 0.001 0.002 0.004 ------Molybdenum 7439-98-7 0.001 mg/L <0.001 <0.001 <0.001 ------Page : 4 of 4 Work Order : EM1912087 Client : GEO-ENVIRONMENTAL SOLUTIONS Project : Great Lake Analytical Results Sub-Matrix: WATER Client sample ID S Tank N Tank Bore ------(Matrix: WATER) Client sampling date / time 29-Jul-2019 00:00 29-Jul-2019 00:00 29-Jul-2019 00:00 ------Compound CAS Number LOR Unit EM1912087-001 EM1912087-002 EM1912087-003 ------Result Result Result ------EG020T: Total Metals by ICP-MS - Continued Selenium 7782-49-2 0.01 mg/L <0.01 <0.01 <0.01 ------Silver 7440-22-4 0.001 mg/L <0.001 <0.001 <0.001 ------Boron 7440-42-8 0.05 mg/L 0.05 <0.05 <0.05 ------Iron 7439-89-6 0.05 mg/L 0.06 0.10 0.18 ------EG035T: Total Recoverable Mercury by FIMS Mercury 7439-97-6 0.0001 mg/L <0.0001 <0.0001 <0.0001 ------EN055: Ionic Balance ø Total Anions ---- 0.01 meq/L 0.44 0.44 0.71 ------ø Total Cations ---- 0.01 meq/L 0.31 0.36 0.54 ------MM524: Heterotrophic (Total) Plate Count @ 22C and 36C Heterotrophic Plate Count (22°C) ---- 1 orgs/mL 530 590 0 ------Heterotrophic Plate Count (36°C) ---- 1 orgs/mL 120 160 0 ------MM696: E. coli & Faecal Coliforms by MF (Chromogenic) Faecal Coliforms ---- 1 CFU/100mL 0 0 0 ------MM698: Total Coliforms and E. coli by MF (Chromogenic) Escherichia coli ---- 1 CFU/100mL 0 0 160 ------Total Coliforms by MF ---- 1 CFU/100mL 0 0 70 ------JET - JET INOX - EUROINOX M-P PREPARED CENTRIFUGAL ELECTRIC PUMPS TECHNICAL DATA Operating range: from 0.4 to 10.5 m3/h with head up to 62 metres.

Acidic water can cause corrosion of pipe-work and seals in the water line, causing costly damage. The Puretec NTS Series reduces green/blue staining commonly noticed on plumbing fixtures meaning that corrosion of the pipe-work has possibly started. These units effectively utilise a calcium carbonate media, which slowly dissolves into the water to lift the pH, protecting the plumbing system from corrosion. Knowing the pH level of your water can help you prevent secondary effects. If the acidity of your water is too high, corrosion can leach out lead and copper from pipes and plumbing as well as damage your water supply system and water heater. SPECIFICATIONS FEATURES & BENEFITS • Neutralise potentially corrosive water with a low pH Model NTS Series • Utilise calcium carbonate media to lift the pH pH range 5.0 - 7.0 • Slow reacting for controlled pH correctors Operating Pressures 200 - 600 kPa • Media fll port for easy maintenance Operating Temperature Ranges 5 - 40°C • Utilise calcium carbonate media to lift the pH Inlet/Outlet Fitting Connections 1” Male Inlet/Outlet • 1” connections means minimum pressure loss • No Power required For more information contact your local stockist or visit us at puretecgroup.com Australia 1300 140 140 | New Zealand 0800 130 140 Page 1 of 2 JULY.2018 NTS Series SYSTEM SPECIFICATIONS AND PERFORMANCE DATA Max Flow Ordering Code Application Backwash Service Flow Lpm Lpm NTS2000 Small to medium building / residence in/out head 20 70 NTS3000 Medium building / residence in/out head 40 90 NTS4000 Medium to large building / residence in/out head 60 100 NTS70-C Commercial building / residence in/out head 70 150 Operating Conditions: 1.
