1 Introduction This Draft Environmental Management Plan (EMP) has been prepared by SMEC Australia Pty Ltd (SMEC) for Cubic Aquatech Pty Ltd (Cubic) to support a development application seeking a Development Permit for Aquaculture over land described as Lot 13 on RP213529, situated at 55 O’Grady Road, Redbank Creek (the project). This EMP and associated Sub-plans have been written in accordance with the following policies, guidelines and legislation:

• Soil Erosion and Sediment Control: Engineering Guidelines for Queensland Construction Sites (Institute of Engineers Australia, 1996);

• Best Practice Erosion and Sediment Control (International Erosion Control Association, 2008); • Queensland Environmental Protection Act 1994; • Queensland Environmental Protection (Water) Policy 2009; • Queensland Nature Conservation Act 1992; and • Somerset Regional Council: Planning Scheme Policy 3 – Catchment Management Analysis Guidelines.

1.1 Project Description The project proposes the development of an aquaculture facility on land described as Lot 13 on RP213529, situated at 55 O’Grady Road, Redbank Creek.

It is project proposes the establishment of a facility for growing of Black Tiger prawns (Penaeus Monodon), an Australian native marine crustacean. Black Tiger prawns are a fast-growing subtropical – tropical species, they are one of three prawn species farmed in Queensland and the main species farmed in Australia.

Unlike traditional prawn aquaculture operations in Qld that require purpose-built earthen ponds, usually constructed on coastal lands adjacent to estuarine river systems, the project involves tanks holding saltwater housed within a dedicated building and fitted with marine aquarium adapted technology to maintain constant temperature and water quality.

1.2 Project Scope The project scope includes construction of the building to house the tanks, installation of pumps, pipework and electrical supply and ongoing operation of the aquaculture facility once the construction phase of the project is complete. Detail of construction and operational activities are listed in Section 2.1.

1.3 EMP Context This EMP has been prepared as a draft document and makes assumptions on behalf of the appointed Construction Contractor and future operational staff. The EMP sets the benchmark in terms of environmental management on site, however, the appointed Contractor and operational managers must complete their own risk assessment based on construction and management methodology and update specific requirements within the EMP and sub plans over the duration of the project to reflect adaptive management approaches. While this EMP has been prepared by SMEC, ultimate responsibility for compliance with relevant legislation and approvals lies with the construction and operational managers.

The EMP aims to ensure that potential environmental impacts and management requirements associated with the project are identified and appropriate mitigation methods are developed to minimise potential environmental harm. The EMP provides a framework for ensuring that all persons and organisations involved in the project are aware of their environmental management obligations.

1.4 EMP Objectives The key performance objective of this EMP is to comply with all relevant environmental legislation and regulations, including avoiding environmental harm.

This EMP defines environmental obligations and other legal and regulatory controls relevant to the construction and operation of the Project. Key environmental objectives and targets for the Project are shown in Table 1.

Introduction

Table 1: Environmental Objectives and Targets

ASPECT OBJECTIVE TARGET

Soils and Geology To apply soil erosion and sediment control principles to minimise soil erosion, sediment runoff.

• Effective erosion and sediment controls are installed and maintained throughout construction.

• Effective reinstatement of disturbed surfaces at completion of construction.

Ecology To protect flora and fauna within and adjacent to the site during construction and operation.

• On-site vegetation clearing is minimised.

• No damage to native vegetation beyond the site boundary.

• Potential impacts to native flora and fauna are minimised.

• Effective reinstatement/landscape of the site following construction.

Water Quality To avoid pollution of waterways by, waste water, fuels, oils, or chemicals stored used on the site and avoid sedimentation of waterways.

• Effective materials handling, and sediment and erosion control is implemented to ensure no spills of fuel, hazardous substances or sediment into waterways.

• Suitable offset distances from waterways are maintained.

Air Quality To minimise potential air pollution from construction and operational activities.

• Construction and operational activities do not result in excessive air quality impacts that cause environmental nuisance or harm.

Noise and Vibration To minimise potential impacts of noise and vibration from construction activities.

• Effective noise and vibration control measures are maintained throughout construction and operation.

Visual Amenity and Lighting

To protect landscape character and visual amenity values of the site and surrounds

• Effective screening, integration and siting of facilities to reduce visibility.

• No light spill from night time activities into neighbouring properties.

Waste To minimise waste resulting from construction and operational activities.

• Accurate records are maintained of all waste leaving the site.

• Tracking of any regulated wastes is maintained.

• Waste is disposed of at licensed facilities.

• The waste hierarchy of avoidance, reuse, recycling and disposal of waste is adopted during construction and operation.

1.5 EMP Sub-plans Sub-plans have been prepared to address each of the environmental aspects relevant to the Project. Each of these sub-plans has specific management measures, monitoring and reporting requirements that must be implemented. The EMP Sub-plans, which are provided in Section 10, are listed in Table 2.

2 Project Information 2.1 Construction Scope of Works The construction of the project will involve the building of a 14.04m x 25.54m insulated colour-bond clad shed on a concrete slab base. This structure will house the tanks which will be used for growing of the prawns and the associated treatment of water. The area where construction will take place is level and is cleared of native vegetation. Correspondingly, minimal earthworks and no clearing of native vegetation is proposed as part of the construction. The area proposed for construction of the shed is shown in Figure 2 below.

Figure 2 Proposed location of the shed which will house the Aquaculture facility

The proposed design of the shed and general layout of the aquaculture facility is illustrated in Appendix 1.

2.2 Future operations

The future operations of the facility fill focus on the production of two crops of prawns per annum. The major components of the facility are the 100m2 production tank and the 50m2 water treatment tank. A series of smaller tanks associated with various component stages of the water treatment process will also be installed. Details of the operational aspect of the project are included in the Cubic Aqua Tech Aquaculture Operation Plan attached as Appendix 2.

Key features of the future operation of the facility are:

• The facility is located indoors within an insulated shed, noise and vibration generated by the activity will subsequently be very minor

• Pumps used are small capacity electric pumps (see Appendix 2) which fill further reduce the potential for generation of excessive noise

• No by-products or waste from the aquaculture production process will be released to the environment on site. All waste will be disposed of by a licensed waste contractor at an appropriately licensed facility. Sampling of the waste product produced by an identical process at Cubic Aquatech’s trial facility in China has been laboratory tested and the results of this testing did not indicate levels of contaminants which would require disposal at a specialised contaminated land facility. The laboratory analysis results are attached as Appendix 3.

• No food processing will be undertaken on site.

3.2 Environmental Duty Under Section 319 of the EP Act, everyone has a ‘general environmental duty’ to not undertake an activity that causes or is likely to cause environmental harm unless all reasonable and practicable measures are taken to avoid that harm.

The EP Act also imposes a ‘duty to notify’ (Section 320A - 320G) upon any person who becomes aware that their activities, or the activities of somebody working with them, has caused or threatens to cause ‘material’ or ‘serious’ environmental harm that is unlawful under the EP Act.

The EP Act defines environmental harm as ‘any adverse effect, or potential adverse effect (whether temporary or permanent and of whatever magnitude, duration or frequency) on an environmental value, and includes environmental nuisance.’

Material environmental harm is defined as:

‘environmental harm (other than environmental nuisance): a. that is not trivial or negligible in nature, extent or context; or b. that causes actual or potential loss or damage to property of an amount of, or amounts totalling,

more than the threshold amount but less than the maximum amount; or c. that results in costs of more than the threshold amount but less than the maximum amount being

incurred in taking appropriate action to: i. prevent or minimise the harm; and

ii. rehabilitate or restore the environment to its condition before the harm.’

Serious environmental harm is defined as:

‘environmental harm (other than environmental nuisance):

a. that is irreversible, of a high impact or widespread; or b. caused to:

i. an area of high conservation value; or ii. an area of special significance, such as the Great Barrier Reef World Heritage Area; or

8 Compliance 8.1 Environmental Inspections and Monitoring During construction the Construction manager/foreman will undertake inspections to evaluate the effectiveness of any environmental controls in place. This will become the responsibility of the principal once the facility becomes operational. The inspections to be undertaken for the duration of construction/operations and are summarised in Table 4. Refer to the Site Inspection Checklist in Appendix C.

Table 4: Environmental Inspections

TYPE OF INSPECTION FREQUENCY RESPONSIBLE PERSONNEL

Visual inspections of site conditions including visible dust, waterways and drainage lines, site runoff, excavations, storage areas, crib areas etc.

Daily when work is occurring on site.

Construction manager/Foreman

Visual inspection of any erosion and sediment controls for condition and effectiveness.

At least daily (when work is occurring on-site). At least weekly (when work is not occurring on-site). Within 24 hours of expected rainfall; and Within 18 hours of a rainfall event of at least 20mm.

Construction manager/Foreman

Monitoring will be undertaken by the Contractor during construction to ensure the environmental controls are functioning adequately. For the duration of construction, monitoring will be conducted of all relevant environmental aspects as outlined in the Sub-plans contained in Section 10.

8.2 Corrective Actions Where monitoring or complaints indicate that the works are not meeting the environmental obligations, corrective actions must be undertaken. The Contractor will implement all corrective actions identified by the Principals Representatives. Works that do not meet environmental obligations must be ceased until corrective actions can be developed and implemented. The timing of installation of control measures will be critical to ensuring that environmental obligations are met within the required timeframe and that controls are effective in achieving their purpose. For each non-conformance identified, the Non-conformance Register (Appendix D) is to be completed showing a description of the non-conformance and the corrective actions taken to rectify the matter.

8.3 EMP Review The principal is required to review and update the EMP to capture any future changes to the project scale or operational methods. Revisions to this EMP may be required during the project to reflect changing circumstances or identified deficiencies. Revisions may result from:

• Management review; • Inspections; • Complaint reports; • Changes to the Project, site compound and operational changes etc; or • Changes to legislation or the conditions of approvals/permits.

Environmental Risk Assessment

15



9 Environmental Risk Assessment An environmental risk assessment was conducted of the environmental aspects associated with the proposed project. This risk assessment:

• Identified the environmental values of the project area; • Assessed the potential impacts that may occur from construction and operational activities; • Proposed mitigation measures to be applied to reduce the risk; and • Assessed the residual risks from potential impacts after the application of mitigation measures.

The risk was evaluated based on the likelihood of occurrence and the consequences of potential impacts resulting in an overall Risk Rating as shown in Table 5 below.

Introduction

The Cubic Aqua Tech Pty Ltd is a start-up company registered in Australia. The company will

introduce innovative and highly efficient aquaculture technology into Australia. It is proposed

to utilise OCTO technology for filtration and treatment of saltwater. This technology has been

developed over a 15 year period of marine aquarium equipment manufacture. The company

has a high reputation in the aquarium industry. Moreover, the use of this technology has

potential to benefit an expansion of Australia’s aquaculture industry.

The purpose of this report is to describe the technology and operational phase of the proposed

aquaculture facility. This operational plan explains the operating process of the aquaculture

facility proposed to be established at 55 O’Grady Road, Redbank Creek. It is for planning

assessment purposes only by Somerset Regional Council and by State Government agencies.

The information and photographs included in the report are provided by OCTO research and

technology team of a prototype aquaculture facility that was were established at the Shenzhen

OCTO research centre.

Farming Tank

Photograph 1. Farming tank Photograph 2. Farming tank

Photograph 1. shows the basic appearance of the farming tank. The livestock will be kept in

this tank from Post larvae to Adult. The farming period is 120 days to harvest. The size of

prototype shown in photograph 1 is around 20 sqm in surface area. The external shape is round

as it easy to distribute the water pressure to avoid the tank leaking. The total wall height for the

farming tank is 160cm while the height of water level is no more than 65cm.

3

Photograph 2. is the interior of the farming tank. This picture shows the water colour is brown.

The coloration is due to the use of the brown sugar used in the tank to neutralize the ammonia

nitrogen. The recycled water would be reused after sedimentation and treatment. Moreover,

the tank bottom drains centrally, as shown in Diagram 1. This design helps any waste to

concentrate into the centre of the farming tank for ease of collection.

Sediment Tank

Photograph 3. Sediment Tank

Photograph 3 shows the Sediment Tank -in the second stage of the process, recycled water

drains to the sediment tank. The tank is cone shaped kept in a concrete bund area with

approximately 1/3 of the tank underground, as shown in Diagram 1.

The main function of this tank is to settle the water from the faming tank which contains high

intensity prawn feed, excrement and shed prawn shells. The heavier substance will deposit to

the bottom of the tank with the sediment pumped to the Waste collection tank, as shown in

Photograph 7. The recycled water at the top of the sediment tank, is clearer than the waste

water deposited to the bottom of the tank, however, the water to be taken from the top of tank

after sediment treatment still contains micro organic compounds dissolved in the water. The

next stage of treatment is the protein skimmer, which is functioned to filter any dissolved

organic matter (DOM).

4

Protein Skimmer and ‘Urine Tank’

Photograph 4. Skimmer tank Photograph 5. Urine Tank

Photograph 4. is the protein skimmer Q15 which contains fifteen 240 voltage output skimmer

pump manufactured by OCTO. The material and appliance in this equipment are designed and

certified to a marine standard.

Protein skimmer uses the physical method to make the water spin with high speed in the

skimmer chamber. A unique characteristic of marine water is that it will release white foam

when spun at high speed. The black hose connected to the top of the skimmer transports the

foam to the ‘Urine Tank’ to settle, which is shown in Photograph 5.

The Urine tank will break down the foam into liquid and pumped to the Collection Tank, as

shown in Photograph 8.

After the skimmer treatment, the water will settle in the water treatment tank, as shown in

Photograph 7.

Water treatment

Photograph 5. Oxidant Dissolution tank Photograph 6. Water treatment tank

After the water treatment in the protein skimmer, the filtrated water will be stored in the

treatment tank, shown in Photograph 6. In addition, the sodium hypochlorite will be added in

the oxidant dissolution tank, see Photograph 5. The soluble sodium hypochlorite is similar to

swimming pool chemicals used to kill any bacterial and algae. The sodium hypochlorite must

be fully dissolved in the oxidant dissolution tank before the treated water is pumped to the

water treatment tank. The sodium hypochlorite needs to be 100% dissolved in the oxidant

dissolution tank to ensure no sodium hypochlorite sediment enters into water treatment tank.

The oxygen supply in the water is continuously provided by the skimmer pumps. Any bacterial

and algae will be killed by chloride compound produced in the chemical reaction producing

sodium and the oxidized compound.

The water will continually be reused after treatment process. The water quality will be

monitored each time as part of the water recirculation. Any chlorine residual will be harmful

to the livestock, if there is any residual. Therefore, the residual of chlorine is carefully tested

before the water is released to the farming tank.

Waste Collection Tank

Photograph 8. Waste Collection Tank

Photograph 8 is the waste collection tank that settles any material which comes from sediment

tank and the urine tank, described earlier in the water treatment process. The material from this

tank will be removed by a licensed liquid waste collector.

Operation

Diagram 1

Diagram 2.

Diagram 2 is a diagrammatic picture of the proposal aquaculture to be established at 55 O’

Grady Road, Redbank Creek. Please note there will only be one farming tank that will have a

surface area no greater than 100sqm in area to be used for the growing of prawns.

8

The water treatment tank proposed is bigger than the prototype shown in Diagram 2 and two

Q15 skimmers will support the water treatment for the proposed aquaculture.

The building material of the shed to house the aquaculture will be similar to a fridge panel and

be made of a galvanised metal frame. The 80-100mm thick fridge panel will be used as the

building wall and roofing given its insulation properties to help maintain the water temperature

between 28-30 Celsius. There will be six (6) standard roller doors and 2 fire doors proposed

within the shed.

Transport

After the initial filling of the tanks, the proposed development will require the occasional

delivery of saltwater to help accommodate the growth in size of the prawns. The total water to

be used at any one time by the aquaculture is 70,000 litres. There will be fresh marine water

delivered every 4 months for each new round of farming. Currently, two farming rounds

proposed per year. An addition of 8000 litres of marine water will be added every round of

farming. This service two purposes. Firstly, the fresh nature marine water is better for Post

Larva to grow. The recirculated water may block the larva gills because of the micro bio floc.

It is safe for juvenile and adult prawn. Secondly, as part of the water replenishment, there will

be some lose of water in the recycling process i.e., the water pump to the Waste Collection

tank.
