This Site Management Plan accompanies an application to Council and DEHP for associated approvals and licenses for the occupation and operation of the above mentioned site for the said purposes of an Extractive Industry - Quarry. The application is to be assessed against the provisions of the Environmental Protection Regulation 2008 and associated policies.
The purpose of this document is to provide a Site Management Plan (SMP) that highlights the actual and potential environmental impacts associated with the proposed activities. Environmental impacts from extractive industries can be significant and long lasting, this SMP aims to ensure that good practice in the management and operations of the quarry are encouraged. The following elements of the quarry have been included in this SMP:
Subsequently, this SMP will provide a description of: 1. How this activity will be conducted on the site;2. Provide a site plan indicating the location of the buildings to house the activities;3. An indication of the production capacity expected by the operator; and,4. Detail any potential environmental impacts associated with these activities, including:
Air emissions;
Noise emissions;
Water quality runoff;
Dangerous Goods Storage;
Waste generation; and
Land contamination and potential dangerous goods.
(Identified to acceptable and agreed limits in accordance with the relevant environmental legislation and standards (ie. Environmental Protection Act 1994 (EP Act)).
This SMP addresses various environmental performance requirements to be implemented on-site by the Site’s Owners/Managers if not already. All persons however, will be responsible for the day to day improvement of his/her environmental duty on site and is also

required to comply with the recommendations of this SMP. Where appropriate this document recommends best practice benchmarks, with which Owners, Managers and Employees are expected to comply.
Notwithstanding, by maintaining and improving where necessary the current environmental measures and day-to-day monitoring program contained in this SMP, the current pro-active environmental management approach adopted by Edith Pastoral Company will be enhanced for the operation of this activity.
It is stated to Council and the Department of Environment and Heritage Protection that the proposed use of the site is consistent with that of surrounding operations to the north of the site, and other nearby approved uses.
Furthermore, the proposed operation of this site given the nature of the business proposing to conduct the activity has the ability to modify and alter specific management measures as required in the event that off-site migration of materials occurs.
1.1 LIMITATIONS OF THE SMP
It is stressed that this SBMP does not negate the need for site Owner/s, Managers and Employees to continue to improve the environmental performance of the business. The recommendations provided are to be implemented into the operations of the Environmentally Relevant Activities not only to gain the relevant environmental licenses, permits or approvals deemed necessary for activities carried out on this site but to ensure that the business is maintaining its Environmental Duty.
Further, compliance with this SBMP does not necessarily exempt the operators from prosecution or ensure compliance with legislation. It remains the responsibility of the operator, employees or manager undertaking these activities to satisfy their own “General Environmental duty”.
1.2 GOALS OF THE SMP
The intention of this SMP is provide clarification as to the ACTUAL and POTENTIAL release of contaminants, the environmental impacts and management solutions required to ensure that the operation of this facility neither causes environmental/human harm or nuisance. The individual technical reports which have been prepared by each specialist consultant to accompany this application, set out in full a detailed assessment of the project have been provided and partially addressed herein this report.
Areas where it is anticipated that environmental harm/nuisance may occur will be investigated and where required strategies will be formulated for the minimisation of such harm to provide a framework for the monitoring of performance of these strategies.
The overall goals of the SBMP are to:

1.3 SITE DESCRIPTION
The site is located at 310 Gregors Creek Road, Gregors Creek, and is located amongst rural lands with a small number of sensitive uses nearby and existing extractive industries to the north (figure 1). The site is situated to the east of the Brisbane valley Highway providing excellent access to the site from surrounding towns, with direct access from Gregors Creek to the north.
The site is well situated within an amphitheater surrounding, reducing direct line of site to the existing sensitive receivers in the locality. There are no existing buildings to be removed. The site is void of any significant vegetation with only scattered low density shrubs and scattered trees (5-10m).

North: Rural Lands and agriculture lands, existing quarry; East: dense bushland and high ridge line; South: number of sensitive receptors and Brisbane River; and West: Rural Lands and agriculture lands
1.4 DAY OPERATIONS
The site is proposed to be operational for up to twelve (12) hours of the day adjacent to a separate concrete batching plant, and will provide aggregates for that plant. Operation hours will most likely to be between 0600hrs and 1700hrs. Daily operations will include the following activities for production:
Excavation of materials with the use of dozers, excavators, and other heavymachinery;
December, 2015 JT Environmental PTY LTD
JT1582 – 310 Gregors Ck Rd - Site Based Management Plan - Quarry 9
Crushing and screening of minerals;
Stockpiling of assorted aggregates for use off-site; and
Loading of front end loaders to deliver aggregate material to the adjacent quarry;
It is proposed for trucks to be entering and exiting the plant via the haulage road as shown on the attached site plans. The haulage road is to be made of a compact unpaved surface which as stated in the dust management plan by JT Environmental will be regularly watered and maintained for dust suppression.
The Quarry has been appropriately designed and located so as to reduce line of site to surrounding residents and create minimal disturbance to the environment.
1.5 ENVIRONMENTAL MANAGEMENT
Implement environmental policies and practices
The overall goal of the Environmental protection Act 1994 is to protect Queensland’s environment while allowing for development that improves the total quality of life, now and in the future, in a way that maintains the ecological processes on which life depends (ecological sustainable development).
An SMP addresses the impacts of noise, air quality, waste and any other relevant environmental issues associated with the proposed development that could pose a significant risk to the environment, if not properly controlled, monitored and/or managed.
This SMP is a statement of the facts as known at time of preparing the report; it will detail concise control measures and procedures, checklists and any relevant records (permits, waste disposal etc.)
The overall goal of a management plan is to increase performance of the development while reducing environmental harm or nuisance as much as possible by implementing good management practices. Key components of this SMP include but not limited to:
Monitoring and reporting Records Staff training/awareness Complaints responses and forms Emergency and incidents reports/forms
The following reports in particular have been referenced with the relevant criteria or sections to support this management plan where relevant.

2.0 BACKGROUND INFORMATION AND RESEARCH ASSOCIATED WITH QUARRY OPERATIONS
2.1 PROPOSED QUARRY
Stone quarrying is a multistage process by which rock is extracted from the ground and crushed to produce aggregate, which is then screened into the required sizes for immediate use, in this case for the adjacent concrete batching plant namely. Other processes the aggregate can be used for is being coated with bitumen to make bituminous macadam (asphalt).
The process involved for small scaled quarry operations is relatively straight forward and simple, and includes the following operations:
Rock blasting (restricted to midday)
Crushing – where aggregates are broken down to produce various sizes;
Screening – the crushed aggregates are screened into various size categories; and
Aggregate supply system – Various aggregates sizes are assorted in to stockpiles to betransported off-site.
Figure 3: Existing quarry to the north at Coominya – similar scale to the proposal.
The proposed quarry falls into the category of surface mining, which is simply the process of stripping surface vegetation, dirt, and layers of bedrock from an open pit quarry for building materials. As well as rock blasting to extract aggregates, the following heavy machinery will also be used;
Motor graders;
Mass excavators;
Articulating truck;
Bulldozers;
Haul trucks;
Hydraulic & electric shovels;

JT1582 – 310 Gregors Ck Rd - Site Based Management Plan - Quarry 13
Figure 4: Examples of heavy machinery for operations
Rock Blasting:
Rock blasting in quarries is a standard and necessary process, and is to be highly controlled. The potential impacts from blasting include air borne dust particles, and air-borne vibrations referred to as overpressure and ground vibrations. Blasting can have significant affects on the local amenity for an area; subsequently all blasting activities are to be conducted under strict guidelines of the Environmental Protection Act.
The proposed design of the quarry ensures compliance with the regulatory limits stipulated by the Ecoaccess 2006 Guidelines. These regulations limit overpressure levels (noise) to 115dB (linear) for 9 out 10 consecutive blasts, which is readily achieve d as detailed in the noise assessment by JT Environmental.
It is to note that from the modeling conducted, the blasting impacts are to be well below the regulatory limits for human comfort, and orders of magnitude below the levels that would could cause structural damage to properties. The existing separation distance to the sensitive receiving environments allows the development to comply with these regulations as no property is within a 1.1km radius of the proposed quarry. Such compliance demonstrates that no structural damage to any properties in the locality will occur.
Furthermore, blasting will be conducted by professionally qualified personnel in strict accordance with both regulatory requirements, with engineers surveying the quarry face prior to blasting. All blasting will also be limited to midday, to ensure no unnecessary impacts occur during the morning or evening periods. Both the AQA and the NIA demonstrate that compliance can be achieved and that no unacceptable nuisance will be experienced at the sensitive receiving dwellings.

JT1582 – 310 Gregors Ck Rd - Site Based Management Plan - Quarry 14
2.2 PRIMARY CRUSHING
The crushing and screening process can result in an increase in noise and air quality emissions, especially during high wind events. Both the AQA and the NIA have included this process in the desktop modelling and demonstrated that no loss of amenity for the dwellings in the locality will be a result of operations on-site.
In stone quarries or in very "boney" gravel pits, large material usually is reduced in size by either a jaw (Figure 1) or a gyratory crusher. Both types are compression crushers. Although economical, they have the tendency to create thin, elongated particles. Particle shapes sometimes may be a problem for Producers of hot mix asphalt. In some operations impact crushers are used for primary crushing, but they may have a slightly higher cost per ton. Impact crushers may upgrade poor-quality aggregate and increase separation, such as removal of rebar from concrete in recycling operations.
Figure 5: example of jaw crushing and cone crushing units
After primary crushing/reduction the resulting aggregate generally is placed in a large "surge" pile where the aggregate may be fed into the secondary operation whenever convenient. Care is always taken when building up and loading out surge piles, as this step may be a major source of segregation of material going to the secondary plant. Variation at this point may affect both mineral quality and gradation.
Drawing from an inverted cone over a load-out tunnel works well after material has been deposited and left undisturbed to form the walls of the draw-down cone. If the need ever arises to consume the entire pile, care is taken to thoroughly mix the older material a little at a time with fresh product to make the surge as uniform as possible as the aggregate is being pushed into the tunnel. If the operation relies on end loaders to feed the secondary plant from the surge pile, the same care is taken to mix coarse with fine material from the outside to the inside of the pile.

2.3 SECONDARY AND TERTIARY CRUSHING
Secondary and tertiary crushing, if necessary, are the final steps in reducing the material to a desired product size. Historically, cone and roll crushers were the most common choice crushers, but in recent years impact crushers are more widely used. These crushers also are sometimes used as primary crushers for fine-grained gravel deposits.
The cone crusher (a compression type) simply crushes the aggregate between the oscillating cone and the crusher wall (Figure 3). Clearance settings on this equipment are required to be checked and maintained as part of standard operating procedure.
Figure 6: Cone Crusher
As with other compression crushers, the cone crusher yields a somewhat elongated and slivery particle shape. This may be minimized, however, by "choke" feeding the crusher. This technique will also make the shape and size more uniform. One way to choke feed is with a surge hopper and a controlled belt-feed to the cone crusher (Figure 3). Automatic level controls measure the head of the material over the top of the cone (Figure 4).
A roller crusher (Figure 4) is another compression type crusher that simply breaks the material by pinching the aggregates. These types of crushers are often found in gravel operations. Roller crushers have constant maintenance problems and are prone to excessive wear. The rollers are required to be checked frequently to insure proper clearance and uniformity across each roller. Rebuilding and remilling the roller is a standard operating procedure.

Figure 7: Roller Crusher
Screening is carried out at various stages of the crushing process. The screening process involves sheets of mesh with the required apertures for each rock size. The screens (mesh) are vibrated by a rotating transverse shaft, which is machined to be unbalanced so that the required vibratory motion is available to agitate the aggregate. The mesh sizes allow the aggregate to be assorted according to each material size, from large aggregates at the top to the smaller aggregates at the bottom.
2.4 SCREENING
Screening is another technique to control both quality and gradation of the aggregate product.
Figure 8: Screening process (mesh for separation).

JT1582 – 310 Gregors Ck Rd - Site Based Management Plan - Quarry 17
PRODUCT QUALITY
If deleterious material exists at undesirable levels after crushing and may be identified as being predominantly in one size range that is not needed for product size, the material may be screened out (namely, fines or top size). This step may occur between crushing’s so that an opportunity exists to recreate the same size downstream, if needed, to create a product. The screened-out lower-quality material may be used for a lower quality product or wasted if no use exists. The rinse screen (Figure 8) is also commonly used. By running the material over a screen that retains the entire product, enough clay and deleterious fines to make the product acceptable may be rinsed away.
2.4.2 GRADATION CONTROL
The best technique for gradation control is screening (Figure 9).
Screening may be done wet or dry, depending on the kind of aggregate being processed and the degree of consistency required for each product. Washing, for example, may be necessary to clean a concrete aggregate, but may not be needed for hot mix asphalt products, which can contain more fines. For gradation control alone, however, consistency sometimes may only be maintained by using wet screening, especially for hot mix asphalt products. Gradation consistency is usually an overriding factor for a hot mix asphalt customer. Water volume and flow direction are critical in wet screening. Frequent checking of gradation is a standard operating procedure.
Figure 9: Screening
The screening process produces the various aggregates required for the particular use off-site. mineral sizes to be produce are unknown at this stage but the images below provide examples of the aggregates produced at the existing quarry to the north owned and operated by Edith pastoral Company, and is to be similar in scale to the newly proposed quarry for this application.

JT1582 – 310 Gregors Ck Rd - Site Based Management Plan - Quarry 18
2.5.3 SCREENING
Dry screening is a slight misnomer because the material passing over the screen decks is wet, ranging from slightly damp to very wet, depending on conditions such as rain or subsurface moisture. Non-washed screening is a more accurate description of this screening process. High moisture is a concern because the wet aggregates may cause some material to become sticky and bind together, making the aggregate harder to separate. Furthermore, high-moisture conditions may cause binding of lower screen decks, causing override of the material rather than separation. If these conditions are encountered, the Producer may need to establish a balance between the moisture content of the incoming material and the feed rate through the screens. This balance is required to be made for each hour of operation. If reduced feed rates do not solve the problem or is too costly, washing or an additional screen area may be needed.
Sometimes screening variation is too great even under the most favourable of conditions. When this occurs the Producer is required to check that the equipment and the screen cloth are in good repair. The most common reason for high screening variability is the tendency to push too much material over a screen. The only way to maintain a bed of material thin enough for optimum efficiency is to provide enough screening to allow the desired rate of production. Standard operating procedures should reflect the maximum feed rate for the design of the plant. For well-graded products having many sieves, (namely, #53s), gradation control may not be done without first separating the material into fractions. Separating the material into numerous small fractions and then back-blending at a set rate for each fraction may be necessary to control the gradation. Frequent sampling, testing, and control charting are necessary for monitoring because aggregate gradation is subject to so many variables.

The prescribed permits and licenses are required for this development. All site personnel are required to comply with State Legislation and policies as deemed relevant.
5.0 ERA 33 – CRUSHING, MILLING, GRINDING OR SCREENING OF MATERIALS
5.1 AIR QUALITY MANAGEMENT
A review of the project has determined that the most significant air pollutant would be dust (TSP, PM10 and PM2.5). The associated air quality assessment has considered the above pollutants arising from activities from the proposed quarry. The assessment has included the emissions from the quarry alone, as well as the cumulative emissions from bother the quarry and the proposed concrete batching plant (not part of this application) to demonstrate compliance under a worst case scenario during operation. Ambient data was also collected over a 7 day unattended monitoring period and utilised to identify the relevant criteria in accordance with the Environmental protection (Air) Policy 2008.

To comply with the Environmental Protection (Air) Policy 2008; Ecoaccess guidelines; Environmental Protection Regulation and Environmental Protection Act.
Blasting is a main emission source for airborne dust particles (PM10, Pm2.5 and TSP). Screening crushing operations during high-wind events.
December, 2015 JT Environmental PTY LTD
JT1582 – 310 Gregors Rd - Site Management Plan 23
Transporting and loading of aggregates can also potentially cause increased dust particles in the atmosphere.
To comply with the conditions of the Environmental License and supported by the management measures of this SMP.
Source Description Blasting has the ability to increase airborne pollutants (dust) into the atmosphere, especially in high wind events.
During the operation of the site for the purposes of crushing or screening of aggregates, emissions of particulate matter are the primary target emissions source. Given that the recycling of aggregate material results in material with high specific gravity, the possibility of high levels of PM is unlikely. This together with the crushing internally of the equipment will serve to assist in the prevention of off-site migration.
Site delivery with heavy vehicle movement and unloading of raw RAP etc is also a primary emission source from site.
Appropriate Management measures will serve to assist in the reduction of off-site migration of PM. Appropriate assessment of PM10, PM2.5 and TSP has been conducted to demonstrate the project is compliant with the relevant criteria.
Sensitive Receptor locations The site is located within a locality that is dominated by agricultural activities with a number of extractive uses located to the north of the site as detailed in the appendix of this report. These operations are somewhat similar to the proposal, and operated by Edith Pastoral Company. Additionally, the locality is also made up of a number of dwellings that as part of this application have been included in modelling for air pollution from the project.
Given the buffer distance it is considered that with due consideration and pro-active nature of on-site management, there will be no impacts from these emission sources to the identified sensitive uses

JT1582 – 310 Gregors Rd - Site Management Plan 24
Actual or Potential emission source
This actual emission source has the potential to have off-site impacts where direct sensitive receptors were located within close proximity.
This site is located in an area of Gregors Creek where similar uses have been previously and currently used.
This is potential emission source given separation distances and has been assessed accordingly in associated environmental reporting.
Actions or Mitigation Provided
On-site management measures are required to be implemented. These include but are not limited to:
1. Deliveries are to be unloaded by contractors asdirected;
2. All blasting will take into account weatherconditions, conducted during middaytimeframes, and carried out by professionalpersonnel ONLY.
3. Deliveries that are noted as being dominated byhigh levels of particulate matter, appropriatedampening prior to unloading is to occur. This isparamount during high wind periods.
4. Appropriate speed limits of heavy or articulatedvehicles are to be maintained to prevent PMentrainment during manoeuvring.
5. Dust suppression is to be implemented duringcrushing/screening if significant PM migration isobserved.
Suggested associated condition:
Release of Contaminants to the Atmosphere (B2) This environmentally relevant activity must be carried out by such practicable means necessary to prevent the release or the likelihood of release of contaminants that will or may cause environmental harm to the atmosphere.

Emissions To comply with the Environmental Protection (Water) Policy 2009.
To comply with the conditions of the Environmental Authority.
Screening crushing operations during high-rainfall periods are a potential source if not managed appropriately.
To comply with the conditions of the Environmental License and supported by the management measures of this SMP.
Source Description Given the proposed use will expose raw and stockpiles of finished recycled product to the elements, namely rainfall. Appropriate mitigation measure will be required to ensure that all off-site migration is stored/treated prior to discharge.
Overland flow and runoff from stockpiles is the primary emission source of Particulate Matter.
As detailed in the Stormwater and Sediment and Erosion Control Plan, the proposed design will capture, screen and treat sediment laden stormwater prior to discharge from site. The existing dams have been considered best practise management and will serve as a secondary treatment prior to discharge.
Sensitive Receptor locations Treatment strategies have been recommended in the details provided for the site.
JT Environmental considers that the incorporation ofthese particular sedimentation fencing, diversion and open drains, rock check or energy dissipators, sediment ponds and the recycle dam will serve to provide stormwater collection and treatment, and re-use measures on-site.

With no consideration for stormwater runoff from this site, stormwater discharge is likely to contain significant levels of sediment from surface and stockpile runoff. Given the proposed measures to be implemented on-site, it is unlikely that off-site migration of surface PM and runoff from stockpiles will occur.
Considered a potential emission source from site.
Continual monitoring will be conducted to ensure the integrity of the stormwater measures.

5.4 NOISE MANAGEMENT
As detailed in the acoustic assessment report, the project can achieve full compliance with the relevant noise criteria in accordance with the Environmental Protection (Noise) Policy 2008.
The main sources of noise from on-site operations from the plant will b:
Quarry blasting;
Crushing and screening of aggregates;
Aggregate (finished product) loading;
Vehicle manoeuvring on-site.
The sensitive receiving environments that have the potential to be affected by operation noise are located a minimum of 1280km from the plant. This separation distance as detailed in the associated noise report allows appropriate attenuation to meet the criteria of the EP (Noise) Policy 2008.
Operational hours are for up to 12 hours of daily operations, most likely from 6am to 6pm, Occasional after hour access will occur, however as demonstrated from the noise results below, extracted from the noise impact assessment prepared by JT Environmental, all noise criteria are achieved for day, evening and night time periods.
Associated distance attenuation between the subject site and off-site receptors provided for the following calculation:

have been included in all desktop modelling for predictions of future noise impacts at these locations.
Given the buffer distance it is considered that with due consideration and pro-active nature of on-site management, there will be no impacts from these emission sources.
No noise will impact on any sensitive receiving environment based on the separation distance and the localised topography that screens the use.
Actual or Potential emission source
The noise source from this operation is negligible, on the basis of the separation distance. This is considered to be a potential emission source given the locality operations.
The proposed development will not have any adverse noise impacts on existing or future development in the locality.
If significant non frivolous complaints are received site noise monitoring can be conducted by JT Environmental to ensure compliance with the appropriate conditions.
Actions or Mitigation Provided
Modelling conducted on-site, and ambient data collected over 7-day period as detailed in the Noise Impact Assessment – see below.
Noise emission limits will comply with the provisions under the Environmental Protection Act 1994 and associated regulation and policies at any sensitive receiving environment given the significant separation distance provided.
Emission of Noise
(F1) In the event of a complaint about noise that constitutes intrusive noise being made to the administering authority, that the administering authority considers is not frivolous or vexatious, then the emission of noise from the premises to which this development approval relates must not result in levels greater than those specified in the abovementioned criteria table from EP (Noise) Policy.
December, 2015 JT Environmental PTY LTD
JT1582 – 310 Gregors Rd - Site Management Plan 33
The noise recommendations made by JT Environmental are to be adhered to during all hours of operation. The recommendations are:
Performance monitoring during operation of the plant is to be conducted once commissioning has occurred to ensure compliance with the indicated amenity levels detailed in this report;
Ensuring a low speed environment is maintained on-site;
Actively maintaining all plant and machinery to reduce noise emissions;
Truck reversing triggering the reverse beeper is to be avoided where possible –it is to note that the design accommodates forward motion of vehicle manoeuvring; and

9.1 APPLICABLE LEGISLATION
9.1.1 ENVIRONMENTAL PROTECTION ACT 1994
The main piece of environmental legislation relevant to environmental management is the Environmental Protection Act 1994 and it’s supporting regulation and policies. The aim of the EP Act is to protect Queensland’s environment while allowing for development without jeopardising precious natural assets and resources for the future, promoting Ecological Sustainable Development ESD.
In order to ensure that contaminated soil is not illegally disposed of and to ensure that new contaminated site are not created, Section 424 of the Act requires that a disposal permit be obtained from the Environmental Protection Agency (EPA) before removal of contaminated soil. Disposal permits are issues for a specified volume of soil and stipulate the place of disposal and a condition relating to soil removal, treatment and disposal. An application for a disposal permit must be made before removal of contaminated soil under the following circumstances:
From a site recorded on the Environmental Management Register (EMR) ofContaminated Land Register (CLR);
From a site with a remedial action approved by the EPA;
From a site which has been ort is being used for a notifiable activity; or
From a site where contaminated soil is being removed for off-site treatment.
If the owner becomes aware a notifiable activity is being carried out on the land or if the land has been, or is being, contaminated by a hazardous contaminant, the owner must notify the EPA within 30 days as per Section 371 of the Act. Failure to observe procedures including programs and orders, and causing wilful or unlawful environmental harm, are offences under the EP Act and can result in a jail term.
9.1.2 ENVIRONMENTAL PROTECTION REGULATION 2008
One of the main features of the Environmental Protection Regulation 2008 is to list all the Environmentally Relevant Activities (ERA’s), their level, whom administers them and the applicable annual license fee/s. Either the Sunshine Coast Regional Council of the Queensland Environmental Protection Agency (EPA) administers ERA’s. Under this legislation and as previously identified it is the intention of the owners of this site to use it for activities which constitute a notifiable activity.
The Waste EPP provides a strategic framework for managing waste in Queensland. It does this by detailing a preferred waste management hierarchy and various principles as the basis for waste management. The waste Hierarchy moves from the most preferred-waste avoidance, to re-use, recycling, and energy recovery, through to waste disposal, the least preferred.
The principles are:
The polluter pays principle – all costs associated with waste management should,where ever possible, be borne by the waste generator;
The user pays principles – all costs associated with the use of a resource should,where possible, be included in the price of goods and services development fromthat resource; and
Product stewardship principle – the producer or importer of a product shouldtake all reasonable steps to minimise environmental harm from the production,use and disposal of the product.
The hierarchy and principles provide the basis for waste management programs that may be required as a condition of approval for an ERA for industry. Given the intended use of this site once operational waste minimisation and especially re-use id the primary purpose behind the establishment of this facility.
During the construction phase however the waste management policy provided provisions for the following:
Offences for littering, waste dumping, unlawful disposal of hypodermic needlesand unlawful activities at waste facilities;
A waste tracking system that collects data on waste generation, transportationand disposal with Queensland and interstate;
Requirement for premises generating clinical and related waste, includingpreparing waste management plans, segregating infectious waste, appropriateon-site storage and proper disposal;
A framework for managing and ultimately phasing out certain polychlorinatedbiphenyl’s; and
This has the purpose of achieving the object of the EP Act in relation to Queensland waters
The purpose is to be achieved by providing a framework for:
Identifying environmental values for Queensland waters;
Deciding and stating water quality guidelines and objectives to enhance theenvironmental values;
Making consistent and equitable decisions about Queensland waters thatpromote efficient use of resources and best practice environmentalmanagement; and
Involving the community through consultation and education, and promotingcommunity responsibility.
This has the purpose of achieving the object of the EP Act in relation to Queensland’s acoustic environment.
To achieve the object, the policy:
Identifies environmental values to be enhanced or protected
Specifies an acoustic quality objective; and
Provides a framework for making consistent and fair decisions that best protectQueensland’s acoustic environment; resolving disputes about noise issues;developing noise management programs involving government entities, industrygroups and the community; making accurate and consistent noise assessment;and providing customers with important information about noise.
9.1.7 ENVIRONMENTAL PROTECTION (AIR) POLICY 2008
This has the purpose of achieving the object of the EP Act in relation to Queensland air environment.
To achieve the object, the policy:
Identifies environmental values to be enhanced or protected;
Specifies air quality indicators and goals to protect the environmental values;and
Provides a framework for making consistent and fair decisions about managingthe air environment; and involving the community in achieving air quality thatbest protects Queensland’s air environment.
