This Environmental Assessment Report (EAR) has been drafted for the purposes of detailing information on the management and mitigation of emissions and discharges from the prescribed premises. The objective of the EAR is to provide a risk assessment of emissions and discharges, and information on the management of other activities occurring onsite which are not related to the control of emissions and discharges from the prescribed premises activity. This does not restrict the Department of Environment and Conservation (DEC) to assessing only those emissions and

discharges generated from the activities that cause the premises to become prescribed premises.

Basis of Assessment

The Martin Road Gravel Quarry (the ‘'premises”) has been assessed as a "prescribed premises”, under category number 12 (Screening, etc. of material) within Schedule 1 of the Environmental Protection Regulations 1987 (EP Regs):

Category 12 is applicable to premises on which material extracted from the ground is screened, washed, crushed, ground, milled, sized or separated -

Gravel extracted from the premises will be screened, crushed and sized, prior to being

transported off-site for the production of road base. Approximately 110 000 tonnes per year of gravel will be processed in five stages over a five year period.

1. BACKGROUND

1.1 GENERAL COMPANY DESCRIPTION

B. & J. Catalano Pty Ltd (Catalanos) is a family earthmoving business established in 1962,

specialising in bulk earthworks, heavy haulage, contracting for mining & civil and the supply of basic raw materials.

Catalanos own and operate several sand, gravel and limestone quarries across the South West, metropolitan and Mid-West regions.

1.2 LOCATION OF PREMISES

The premise is located on the Swan Coastal Plain in the locality of Mornington, approximately 150 km south of Perth, Shire of Harvey. The proposed site includes cleared farming land and plantation trees.

1.2.2 Geography and hydrology

The proposed extraction areas are covered with a thin veneer of topsoil, overlying approximately 1 m of laterite cap rock and gravel, which grades into kaolinite clays (20 m deep) before fresh granitic material is encountered.

Groundwater is limited within the area due to the low permeability of the subsurface materials. Small pockets of groundwater may occur at depth below the weathered clays (15-25 mbgl); however extraction will only occur between 1 - 2 mbgl.

1.2.3 Community and Sensitive Premises

The proposed site is surrounded by farming land and tree plantations. The nearest noise sensitive premise is a shed located 2.5km east of the site, which is used on weekends only. Another shed is located 1.1km south of the site; however it is understood this is not used as a place of residence.

1.3 PROCESS DESCRIPTION

The proposed activity involves the use of mobile plant to crush and screen approximately 110 000 tonnes per year of gravel.

The plant comprises a primary jaw, screening plant, secondary impactor and a radial stacker. A trailer-mounted diesel generator powers the plant.

(3)

The process comprises resource preparation, processing and land restoration / rehabilitation, however this assessment focuses on the crushing and screening operations only.

1.3.1 Resource preparation

• Topsoil is scraped up into small piles for later use in rehabilitation (also assists in dust and noise mitigation).

• Laterite is ripped and pushed into a resource dump by a bulldozer.

• Loader takes resource from dump to load the crusher.

1.3.2 Processing

• Electric primary and secondary crushers, powered by self-contained diesel generators, crush the laterite into smaller fragments.

• Screening plant screens out product to obtain the correct product size, which is placed onto stockpiles.

• Product is loaded from stockpiles to road trucks, and is taken off-site.

1.3.3 Rehabilitation

• Completed excavation floor is deep-ripped in two directions.

• Overburden, followed by topsoil is spread across the surface. Rehabilitation is raked to remove rocks and seeded for rehabilitation.

1.4 REGULATORY CONTEXT

1.4.1 Part IV Environmental Protection Act 1986, Environmental Impact Assessment The proposal was not referred to the Environmental Protection Authority (EPA) for assessment.

1.4.2 Part V Environmental Protection Act 1986, Environmental Management

Previously, mobile plant used for crushing and screening of raw materials from Catalano’s pits was licensed under the EP Act; however DEC now regulates the "premises” on which the activity is being undertaken.

The Martin Road Gravel Quarry has been assessed as a “prescribed premises”, category number 12, under Schedule 1 of the Environmental Protection Regulations 1987, and as such requires a licence to operate under Part V, Section 54 of the EP Act.

This assessment was triggered by the application for licence submitted by Catalanos on 5 April 2011. Extra documents prepared by the proponent include:

• Excavation - Environmental Management Plan - Laterite Gravel Quarry, Lot 200 Martin Road, Mornington (September 2009);

• Noise and Dust Management Plan - South West Operations - B&J Catalano Pty Ltd;

• Occupational Noise Survey Report for Martin Road, Benger (September 2010);

• Noise Impact Assessment - Lot 200 Martin Road, Mornington, Shire of Harvey (December 2010); and

• Correspondence dated 18 March 2011, with attached letters of consent from surrounding neighbours.

(4)

These documents deal with the emissions and discharges during the operation phase of the project.

EP Regulations relevant to the proposal:

Environmental Protection Act 1986;

• Environmental Protection Regulations 1987;

• Environmental Protection (Noise) Regulations 1997 (EP (Noise) Regs);

• Environmental Protection (Unauthorised Discharges) Regulations 2004;

Contaminated Sites Act 2006;

• Contaminated Sites Regulations 2003.

1.4.3 Local Government Authority

Lot 202 is located within the Shire of Harvey. The land is zoned "General Farming" in accordance with the Shire of Harvey Town Planning Scheme No.1.

The Shire of Harvey issued an Extractive Industries Licence under the Shire's Extractive Industry Local Law on 9 March 2010. A copy of this approval is held on DEC files.

2.0 STAKEHOLDER AND COMMUNITY CONSULTATION

SUBMISSIONS RECEIVED DURING 21 DAY PUBLIC COMMENT PERIOD

The application for licence details was advertised in the West Australian newspaper on Monday, 30 May 2011, as a means of advising stakeholders and to seek public comments. No submissions were received in response to this round of advertising.

3.0 EMISSIONS AND DISCHARGES RISK ASSESSMENT

DEC considers that conditions should focus on regulating emissions and discharges of significance.

Where appropriate, emissions and discharges which are not significant should be managed and regulated by other legislative tools or management mechanisms.

The following section assesses the environmental risk of potential emissions from the premises. In order to determine the site’s appropriate environmental regulation, an emissions and discharges risk assessment was conducted of the premises using the environmental risk matrix outlined in Appendix A. The results of this are summarised in Table 2.

4.0 GENERAL SUMMARY AND COMMENTS

This licence relates to the proposed Martin Road Gravel Quarry in Mornington. Gravel will be extracted, crushed and screened for the production of road base.

The main emissions and discharges of concern during operation include noise and dust. Additional waste streams may include contaminated stormwater runoff. Emissions of odour and light have been assessed and are not expected to be significant. Additional management tools, including the amendment of the licence, is available to DEC should the management of emissions be found to be insufficient during operation.

The environmental risk of emissions or discharges during operations has been assessed, and standard management conditions are required to ensure Catalanos manages the premises in accordance with regulations, the proposal presented to DEC for assessment, and any other

requirement deemed necessary by DEC. Additional conditions are required to ensure information is communicated to DEC.

The premise has been classified as “low priority" in accordance with DEC’S licensing priority management framework and as such, the licence will be reissued for a period of five (5) years.

The premise is also subject to the provisions of the Environmental Protection Act 1986 relating to causing and reporting pollution, and the provisions of the Environmental Protection (Unauthorised Discharges) Regulations 2004.
