Email: admin@catalano.com.au
2.2 DESCRIPTION OF PREMISES
2.2.1 Location
The Donningtons Gravel Quarry is located within the Shire of Chittering. The site is located approximately 5km south-west of the Chittering townsite and approximately 11km north-east of Muchea in Western Australia.
2.2.2 Community and Sensitive Premises
The surrounding land use includes farming, extractive industry operations, tree plantations and rural small holdings. There are several sensitive residential receptors within 1000m of the extraction stages as depicted on Figure 1.
2.3 PROCESS DESCRIPTION
The site activities involve the use of a mobile plant to crush and screen up to 240,000 tonnes of gravel per year, dependent on demand.
The plant comprises the following:
•
A primary jaw crusher
•
Screening plant
•
Secondary impactor
•
Radial stacker
•
Trailer mounted diesel generator
•
Loader
•
Bulldozer
The process comprises gravel preparation, processing and rehabilitation.
DWER Annual Audit Compliance Report Lot 83 Great Northern Highway
Lundstrom Environmental Consultants Pty Ltd Page 6
2.3.1 Gravel Preparation
•
Topsoil will be stripped and placed in windrows along the edges of the working area to serve as a noise, stormwater and visual barrier.
•
A bulldozer will rip the laterite and then blade it into the crusher sites until a large raw material stockpile has accumulated.
•
The raw material will be loaded into the crusher using a front-end loader.
2.3.2 Processing
•
Electric primary and secondary crushers, powered by self-contained diesel generators, crush the laterite into smaller fragments.
•
The screening plant screens out the product to correctly sized gravel, which is then stacked into stockpiles.
•
The gravel is then loaded from stockpiles to road trucks and taken off-site.
2.3.3 Rehabilitation
•
Progressive rehabilitation will be undertaken as excavation in each area is completed.
•
The completed excavation floor will be deep-ripped in two directions.
•
Overburden, followed by topsoil is spread across the surface. The rehabilitated area is raked to remove rocks and then seeded with pasture grass as outlined in the rehabilitation section of the EIL report (Lundstrom Environmental Consultants Pty Ltd, 2016).
•
Contour bunds are constructed in each extraction stage during rehabilitation to attenuate surface water flows and prevent rill erosion.
•
Rehabilitation has commenced in the stages in which the product stockpiles have been removed as detailed in Section 3.
Revegetation
•
Screening vegetation was planted along a 500m strip along Maddern Road to the east of Stages 5 and 6. Plate 1 in Appendix 2 shows the growth of the plants to date. This area (approximately 0.4ha) forms a part of the total 2.7ha of native revegetation required as a condition of the Clearing Permit 6678.
•
The remainder of revegetation in accordance with CPS 6678 was undertaken in winter 2019.
Plates 2 and 3 in Appendix 2 show that this revegetation has a good strike rate and is
progressing well.

3 PREMISES OPERATION
The premises operation in December 2020 is shown on Figures 2a and 2b.
Extractive operations at the premises commenced in late December 2016 and are now complete aside from some reprocessing activities on Stages 1 and 2 and completion of rehabilitation commitments for all stages as detailed below.
Additional screening of remaining stockpiles in Stages 1 and 2 was nearing completion in December 2020 (see Plate 4 in Appendix 2). Preparation of these stages for rehabilitation is scheduled to commence in early 2021.
All product stockpiles have been removed from Stages 3 to 8. Earth has been smoothed on Stages 3,4, 7 and 8 and contour bunds are being constructed (see Plates 5 and 6 in Appendix 2).
Rehabilitation of Stages 5 and 6 is complete and these stages are now in maintenance and
management (see Plate 7 in Appendix 2). The performance of the rehabilitation will be assessed in winter 2021.
3.1 QUANTITIES OF RAW MATERIALS MINED
A total of 239,760 tonnes of gravel has been extracted from this site during this reporting period, which is within the approved premises production capacity. The extraction has been distributed as follows:
Jan-20 35,100 Feb-20 25,228 Mar-20 18,800 Apr-20 18,039 May-20 3,169
Jun-20 4,962 Jul-20 1,722 Aug-20 1,265 Sep-20 31,309 Oct-20 38,955 Nov-20 28,621 Dec-20 32,590
Total239,760
3.2 COMPLIANCE DOCUMENTATION
Compliance documentation has been submitted for each of the Stages 2 to 8 in accordance with the
conditions of Works Approval W5979/2016/1 prior to commencement of extraction in each of these
stages.
DWER Annual Audit Compliance Report Lot 83 Great Northern Highway
Lundstrom Environmental Consultants Pty Ltd Page 8
3.3 STORMWATER DETENTION BASINS
All stormwater detention basins in each stage have been constructed to capture 2 hours rainfall from
a 1 in 10-year Average Recurrence Interval rainfall event. Photographs of detention basins are shown
on the photographic plates (8 to 18) attached as Appendix 2. During a site inspection on 7
thDecember
2020, it was observed that the detention basin in Stage 3 had burst and the overflow had created a
gully. This basin and the gully was repaired soon after using material from a nearby overburden
stockpile. There was no evidence of stormwater overflow from any of the other detention basins.

4 DUST MANAGEMENT
Measures implemented to reduce dust during extraction operations include:
•
Application of water using a 15kL water cart on unsealed roads and sprinklers on product stockpiles to reduce dust lift-off
•
Internal roads have been surfaced with gravel to minimise dust lift-off
•
Adherence to speed limits on unsealed roads to reduce dust lift-off
•
All loads are covered to reduce dust generation from product transport.
There has been no requirement to apply dust suppressants to the product stockpiles.
DWER Annual Audit Compliance Report Lot 83 Great Northern Highway
Lundstrom Environmental Consultants Pty Ltd Page 10
5 DUST MONITORING
Dust monitoring was not undertaken during the reporting period because there was no crushing on
site during this time. There is no requirement for dust monitoring when the crusher is not operating
at the site.
DWER Annual Audit Compliance Report Lot 83 Great Northern Highway
Lundstrom Environmental Consultants Pty Ltd Page 11
6 REPORTING
This Annual Environmental Report & Audit Compliance Report are required to be submitted by 10
thJanuary 2021.
Information that fulfils specific reporting conditions of the Licence including complaints management, noise verification reports and dust trigger exceedances are provided below.
6.1 COMPLIANTS MANAGEMENT
No known complaints have been received during the reporting period. The Environmental Health Officer at the Shire of Chittering was contacted via email and voicemail in November and December 2020 to check if there had been any complaints, but no reply was received. On this basis, it is assumed there have not been any complaints.
6.2 NOISE VERIFICATION REPORTS
A Noise Verification Report was undertaken by Lloyd George Acoustics in February 2019 at the commencement of Stage 4 operations (see Appendix 4 of 2019 AER report). The noise verification
was conducted under ‘worst case’ wind direction and speed conditions. The assessment found thathigher than predicted LA10 noise levels may occur at the closest sensitive receptor. It was suggested that this could be mitigated by 3m high stockpile mounds between the crushing plant and dozer working areas and the eastern residences. This was put in place during the crushing operations.
No further noise verification assessments were undertaken as it was difficult to distinguish noise associated with the operations from that occurring as a result of roadworks associated with the Northern Link construction, as well as finding a suitable time of worst-case scenario wind conditions.
6.3 DUST TRIGGER EXCEEDANCES
As discussed in Section 5 there was no requirement for dust monitoring at the site during the reporting period therefore there are no dust trigger exceedance events to report.
Catalano’s have a water cart on site which is employed to keep the unsealed roads and stockpiles
damp during dry, windy conditions.

Introduction
This Introduction is not part of the Licence conditions.
DER’s industry licensing role
The Department of Environment Regulation (DER) is a government department for the state of Western Australia in the portfolio of the Minister for Environment. DER’s purpose is to advise on and implement strategies for a healthy environment for the benefit of all current and future Western Australians.
DER has responsibilities under Part V of the Environmental Protection Act 1986 (the Act) for the licensing of prescribed premises. Through this process DER regulates to prevent, control and abate pollution and environmental harm to conserve and protect the environment. DER also monitors and audits compliance with works approvals and licence conditions, takes enforcement action as appropriate and develops and implements licensing and industry regulation policy.
Licence requirements
This Licence is issued under Part V of the Act. Conditions contained within the Licence relate to the prevention, reduction or control of emissions and discharges to the environment and to the monitoring and reporting of them.
Where other statutory instruments impose obligations on the Premises/Licensee the intention is not to replicate them in the licence conditions. You should therefore ensure that you are aware of all your statutory obligations under the Act and any other statutory instrument. Legislation can be accessed through the State Law Publisher website using the following link:
http://www.slp.wa.gov.au/legislation/statutes.nsf/default.html
For your Premises relevant statutory instruments include but are not limited to obligations under the:
Environmental Protection (Unauthorised Discharges) Regulations 2004 – these Regulations make it an offence to discharge certain materials such as contaminated stormwater into the environment other than in the circumstances set out in the Regulations.
Environmental Protection (Controlled Waste) Regulations 2004 - these Regulations place obligations on you if you produce, accept, transport or dispose of controlled waste.
Environmental Protection (Noise) Regulations 1997 – these Regulations require noise emissions from the Premises to comply with the assigned noise levels set out in the Regulations.
You must comply with your licence. Non-compliance with your licence is an offence and strict penalties exist for those who do not comply.

Premises description and Licence summary
An application for a new concurrent works approval and licence was received by the Department of Environment Regulation (DER) on 15 July 2016. The application is to conduct a gravel extraction operation at Lot 83 Great Northern Highway, Chittering.
The application proposes the use of a mobile crusher and screen with a design capacity of 6000 tonnes per day and a nominated throughput of 240,000 tonnes per year hence the premises is a prescribed premises for the purposes of Part V of the Environmental Protection Act 1986 (EP Act) in category 12.
Category 12 screening etc. of material is defined in the Environmental Protection Regulations 1987 as premises on which material extracted from the ground is screened, washed, crushed, ground, milled, sized or separated.
B. & J. Catalano Pty Ltd (the applicant) was established in 1962 as a transport and earth moving operation in the south-west of Western Australia and since then has expanded into the
Metropolitan and Midwest regions with over 300 employees. The applicant operates a number of basic raw material quarries and its customers include large corporations, local and state
government, mining companies, builders and contractors.
The application supporting documentation outlines that the proposal is to extract gravel within 8 operational stages with a total area of 40.2 hectares under an Extractive Industry Licence (EIL).
Planning approval and an EIL have been granted by the Shire of Chittering for the operation for a period of five years, expiring 30 June 2021. The proponent may apply for an extension of the EIL for two further periods of up to two years each, bringing the total potential lifetime of the operation to nine years. The area is zoned as ‘Agricultural Resource’ in terms of the Shire of Chittering Town Planning Scheme No. 6.
An application for a permit to clear native vegetation (CPS 6678/1) under the EP Act was received by DER in July 2015. The clearing permit was granted by DER in August 2016.
There is no history of prosecution or of any formal statutory compliance/enforcement notices issued under the EP Act by DER to B. & J. Catalano Pty Ltd.
The Lot 83 Great Northern Highway Gravel Quarry is located within the Shire of Chittering. The site is located approximately 5km south-west of the Chittering town site and approximately 11 kilometers (km) north-east of Muchea.
The proposed extraction area is located next to the Darling Scarp within the southern section of the Dandaragan Plateau. The property lies in the Swan-Avon Region. The surrounding land use includes farming, extractive industry operations, tree plantations and rural small holdings.
Environmental Protection Act 1986 Page 4 of 16 Licence: L8988/2016/1
File Number: DER2016/001511 IRLB_TI0672 v2.9
The application supporting documentation details that Lot 83 consists of cleared grazing land, areas of remnant native vegetation, remnant pine plantations, rehabilitated clay pits and associated detention ponds from the previous clay extraction operations undertaken by owner Austral Bricks (WA) Pty Ltd. Clay extraction was undertaken in the southern section of Lot 83 between 2003 and 2013 under previously approved EILs. There is no infrastructure on site associated with this previous operation.
There are several sensitive residential receptors located within 1000 metres (m) of the extraction stages. Map reference A depicts the sensitive receptor located within Lot 83. Map references S1, S2, S3, S4 and S5 depict the location of sensitive receptors within 1000m of the premises. The location of the sensitive receptors is depicted in the map of site and surrounds in Schedule 1.

3 Executive summary of proposal and assessment
An application for a new concurrent works approval and licence was received by the Department of Environment Regulation (DER) on 15 July 2016. The application is to conduct a gravel extraction operation at Lot 83 Great Northern Highway, Chittering.
The application proposes the use of a mobile crusher and screen with a design capacity of 6000 tonnes per day and a nominated throughput of 240,000 tonnes per year hence the premises is a prescribed premises for the purposes of Part V of the Environmental Protection Act 1986 (EP Act) in category 12.
Category 12 screening etc. of material is defined in the Environmental Protection Regulations 1987 as premises on which material extracted from the ground is screened, washed, crushed, ground, milled, sized or separated.
B. & J. Catalano Pty Ltd (the applicant) was established in 1962 as a transport and earth moving operation in the south-west of Western Australia and since then has expanded into the Metropolitan and Midwest regions with over 300 employees. The applicant operates a number of basic raw material quarries and its customers include large corporations, local and state government, mining companies, builders and contractors.
The application supporting documentation outlines that the proposal is to extract gravel within 8 operational stages with a total area of 40.2 hectares under an Extractive Industry Licence (EIL).
Planning approval and an EIL have been granted by the Shire of Chittering for the operation for a period of five years, expiring 30 June 2021. The applicant may apply for an extension of the EIL for two further periods of up to two years each, bringing the total potential lifetime of the operation to nine years. The area is zoned as ‘Agricultural Resource’ in terms of the Shire of Chittering Town Planning Scheme No. 6.
An application for a permit to clear native vegetation (CPS 6678/1) under the EP Act was received by DER in July 2015. The clearing permit was granted by DER in August 2016.
There is no history of prosecution or of any formal statutory compliance/enforcement notices issued under the EP Act by DER to B. & J. Catalano Pty Ltd.

The Lot 83 Great Northern Highway Gravel Quarry is located within the Shire of Chittering. The site is located approximately 5km south-west of the Chittering town site and approximately 11 km north- east of Muchea.
The proposed extraction area is located next to the Darling Scarp within the southern section of the Dandaragan Plateau. The property lies in the Swan-Avon Region. The surrounding land use includes farming, extractive industry operations, tree plantations and rural small holdings.
The application supporting documentation details that Lot 83 consists of cleared grazing land, areas of remnant native vegetation, remnant pine plantations, rehabilitated clay pits and associated detention ponds from the previous clay extraction operations undertaken by owner Austral Bricks (WA) Pty Ltd. Clay extraction was undertaken in the southern section of Lot 83 between 2003 and 2013 under previously approved EILs. There is no infrastructure on site associated with this previous operation.
There are several sensitive residential receptors located within 1000m of the extraction stages. Map reference A depicts the sensitive receptor located within Lot 83. Map references S1, S2, S3, S4 and S5 depict the location of sensitive receptors within 1000m of the premises. The location of the sensitive receptors is depicted in the map of site and surrounds in Schedule 1 maps of the Licence.

operation L1.2.1 L1.2.2 - 1.2.3 L1.2.4 - 1.2.5
Condition L1.2.1 sets premises production capacity limits. 240,000 tonnes is the Licence Holders maximum nominated annual throughput.
Compliance documentation for stage 1 was received by DER on 5 January 2017. This has been assessed as meeting the requirements of the conditions of works approval W5979/2016/1. A water management plan submitted as part of works approval application (W5979/2016/1) states that there will be no overflow from the extraction stages due to the construction of detention basins that have capacity to hold a 1 in 10 year, 2-hour duration Average Recurrence Interval (ARI) rainfall event. This has been taken to mean that there will be no overflow under normal rainfall conditions. The risk of the overflow from the detention basins has been assessed below.
Condition 1.2.3 sets the requirement that the Licensee is to operate stages 2, 3, 4, 5, 6, 7 and 8 once compliance documentation has been submitted in accordance with the conditions of the Licence.
Emission description
Emission: Overflow of stormwater beyond designated stormwater detention basins to land that drains towards the west towards Yalyal Brook. Yalyal Brook is a tributary of Ellen Brook. The overflow event could happen in a greater than 1 in 10 year, 2-hour ARI rainfall event.
Impact: Ellen Brook is subject of a water quality improvement plan to reduce nutrients and other contaminants entering the Swan River.
Controls: Yalyal Brook is located more than 2 km downstream from the extraction
