Attachment 3A: Proposed Activities A3A.1 Scope A3A.1.1 Primary activity

Category 35 – Asphalt manufacturing: premises on which hot or cold mix asphalt is produced using crushed or ground rock aggregates mixed with bituminous or asphaltic materials for use at places or premises other than those premises. Production or design capacity from the Environmental Protection Regulations 1987, Schedule 1 – not applicable. Category 61A – Solid waste facility: premises (other than premises within category 67A) on which solid waste produced on other premises is stored, reprocessed, treated, or discharged onto land (RAP). Schedule 1 – 500 tonnes or more per year.

A3A.1.2 Production or design capacity

Production capacity is estimated at 35,000t/annum. The proposed asphalt plant is the plant previously located at the Asphaltech Malaga site under licence number L8447/2010/3. The Malaga Plant will be reconstructed but with significant plant upgrades that include a production upgrade to incorporate recycling solutions when there is enough recycling material and recycling of asphalt becomes viable. The proposed plant is anticipated to include a production upgrade to incorporate recycling solutions when there is enough recycling material and therefore recycling of asphalt becomes viable. However, it is important that the declaration to recycle asphalt be made now in this application. Processed Reclaimed Asphalt Pavement (RAP) (which has already been crushed and/or screened to size for recycling into new asphalt) will be stored and used in the asphalt manufacturing process. The addition of the RAP cold feed system will allow recycling of asphalt materials. Asphaltech, in this application, proposes that RAP will not be incorporated into the mix at initial start-up and accordingly have not shown a mechanism for introduction of RAP into the plant. Asphaltech chooses to wait until a small market, such as the Southwest of Western Australia has enough RAP to make it economically viable to do so. However it is extremely important that this application includes the intention of the use of RAP at this time as Asphaltech have the use of recycled material at the top of their ongoing operational agenda. It is important to add that Asphaltech have a 100% RAP recycling facility at Neerabup near Perth and, in the interim, prior to sufficient material becoming available in the South West, RAP will be transported back to Perth and incorporated in their Perth mixes with only small amounts retained at the Gelorup site whilst waiting transport.

A3A.2 Infrastructure and Equipment

A3A.2.1 Asphalt Plant Installation The asphalt plant proposed will include the following infrastructure and equipment: Cold feeder bins, including conveyor. Dryer drum. Burner. Baghouse, including stack. Height of stack 13.4m. Recovered fines silo. Additional reclaimed filler storage bin. Imported filler silo. Cold RAP feeding line into the mixer. Mixing tower, hot elevator. Air compressor. Control cabin and plant management system. Electrically heated bitumen storage system. Raw material storage bins and reclaimed asphalt storage bin.

A3A.2.2 Site preparation

Limited earthworks will be undertaken to achieve the required topographic levels and level surfaces needed for the installation of the plant. The site is the site of the old Gelorup Quarry crushing and stockpile area and is therefore level, stabilized hard stand already installed with perimeter vegetated screening bunds and drainage management that will be updated.

A3A.3 Processes / Operations

A3A.3.1 Handling, storage and manufacturing – asphalt production process control system

Purpose The purpose of this process control system is to provide instructions, guidelines and adequate control, as applicable, for the handling, storage, manufacturing and delivery of asphalt in the production process. Scope This process control system shall apply to the production and supply and delivery operations. The personnel responsible shall be the Production Engineer and the Plant Operator. Procedure Handling Aggregates The aggregates are to be placed promptly in the correct storage bins. Delivery instructions shall be strictly followed up by transport trucks when delivering a load of aggregate into the company site. All incoming aggregates shall be accompanied by a delivery docket, which shall be signed by the Plant Personnel as evidence of receipt.

Page 7: WORKS APPROVAL APPLICATION...bitumen, additives and, where applicable, fuel in stock and record the unit quantities in stock. The Plant Operator is responsible for taking action to

Asphaltech

Asphaltech Confidential | Page 6

To prevent aggregate contamination, the loader driver shall ensure that loader buckets are kept clean and free from residues of aggregates, asphalt or other deleterious materials when loading cold feed bins, or trucks for transport of materials from site to site. Loader driver shall also monitor stockpiles during loading operations to detect any oversize or deleterious material that will affect the quality of aggregate. Any such material detected shall be brought to the immediate attention of the Production Engineering and shall be removed and discarded. Bitumen The delivery tanker driver shall be responsible for checking the contents of the tanker, mainly Bitumen C320 or C170, prior to loading, to ensure that contamination from any other material does not occur. The Plant Operator shall be responsible for ensuring that: • All bitumen handling equipment – hose fitting, hose pipe - is maintained in good condition and

used in a manner to prevent leakage which may result in injury to personnel and/or damage to the environment.

• Ensure the residual bitumen level in the receiving tank is adequate to allow the full capacity of incoming load to be accommodated with a 10% contingency, prior to any pumping activity occurring.

• All personnel handling bitumen, are to wear the specified protective clothing. • The Plant Operator is to be familiar with all standard operational procedures. A visual risk

assessment is to be made prior to transfer, and the transfer of Bitumen is then to be conducted to the standard procedures.

Additives The Plant Operator shall be responsible for ensuring that additives are handled in such a manner as to prevent loss, damage and/or contamination during loading/unloading procedures, and/or transfer to designated area etc. The Plant Operator shall also be responsible for ensuring that all personnel on the plant site who handle additives: • Wear, where necessary, the required protective clothing and/or breathing apparatus to prevent

contact with, or inhalation of the additives. • Take all necessary action to prevent or minimise environmental damage and follow standard

operations procedures. Storage Aggregates All aggregate in bulk storage stockpiles, and plant cold feed bins, shall be identified by a sign stating the name and size of material to prevent any potential confusion to the truck drivers as well as the loader driver. Aggregates shall be placed onto a firm floor which shall be at least level, or graded towards the face of the stockpile so that water does not settle on the floor and saturate the lower layers of the aggregate via capillary action. The height of any raw materials storage shall be limited to the top of the wall to eliminate the possibility of spillage and reduce the possibility of wind-blown contamination or loss. In dry, windy conditions, the Plant Operator shall be responsible for ensuring that wherever possible, the stockpile aggregate is kept damp by means of the automated “Cannon” sprinkler system to reduce wind-blown dust both from the surface of the stockpile and from the aggregate when being tipped into the cold feed bins.

Bitumen Bitumen shall be stored in a closed tank suitably identified, equipped with an adequate vent system, covered manhole access and a calibrated dipstick for measuring the volume of bitumen in litres. The tanks shall also be suitably insulated and have a thermostatically controlled electrical heating system. Thermostats shall be set to control the bitumen temperature in the range, 150-180°C. Bitumen in storage shall not be heated to more than 190°C. During extended periods where there is no asphalt production, the bitumen storage tank shall be kept as full as possible to maintain the smallest surface area and reduce oxidation and heat loss. Any other storage conditions as nominated by any relevant Statutory Authority shall be adhered to. Hydrated Lime / Baghouse fines Hydrated lime / Baghouse fines shall be stored in silos which are sealed to prevent the entry of water or other foreign material. The silo is equipped with a filtered, air pulse air vent system, and overfill alarm and/or overfill vent pipe which directs vented material into a suitable container, to prevent air borne contamination. Additives Additives, including bagged fibre, pigment and bitumen modifier, are stored under cover to be protected from rain or physical damage. Chemicals, fuel and other All volatile chemicals oils, cleaning agents, LPG cylinders and diesel shall be stored, controlled and identified in accordance with the requirements of all relevant Statutory Authorities and on site operational procedures. Stock Control and Inspection At the end of each Company financial month, the Production Engineer shall check all aggregates, bitumen, additives and, where applicable, fuel in stock and record the unit quantities in stock. The Plant Operator is responsible for taking action to correct any deficiencies, or where necessary, referring the matter to the Production Engineer for resolution. Manufacture Applicable Standards All mix shall be manufactured according to the requirements of AS2150 – Hot Mix Asphalt and AS 2734 – Asphalt (Hot Mixed) Paving – Guide to Good Practice, except in the case of Stone Mastic Asphalt, which shall be manufactured in accordance with AAPA Stone Mastic Asphalt Design & Application Guide. Programming Asphalt Production should not be allowed to proceed until a proper job card has been provided by the relevant personnel the day before, eg Construction Supervisor and/or Construction Engineer. The following information shall be included, but not limited to, in the job card:

(a) Customer name (b) Job site address (c) Mix type, by name and code number, estimated tonnage requirement for the job (d) Truck type requirement

Asphaltech Confidential | Page 8

(e) Any special comments Under no circumstance, shall the Plant Operator start mixing asphalt without the guideline of job card. Pre-start Process The Plant Operator is responsible for undertaking an appropriated pre-start process on the asphalt plant in the beginning of each day. This pre-start process involves pre-heating up the plant to ensure the plant and bag house system is dry and warm as well as identifying any deficiency or risk associated with the plant components. Anything unusual that is identified shall be noted in the prestart checklist as well as reported to the Production Engineer. Asphalt Plant Producing The Production Engineer shall ensure the raw aggregates and bitumen are of consistent and adequate quality. Whilst this will be relying heavily on the Quality Management Systems of the suppliers, a regular Inspection Testing Plan shall be in place to assure consistent and adequate quality. The Plant Operator shall be responsible for choosing the correct mix design recipe during the daily production according to job mix type indicated on the job card. Non-conformance form shall be issued if the job mix type is not followed. Adequate mixing time shall be allowed in the pugmill, as determined by the requirements of the mix design, to ensure thorough mixing of all ingredients and coating of the aggregate particles with bitumen binder. However, unnecessary extension on the mixing time is not permitted to minimise on site activities and maintain quality control. Batch weights shall be measured and recorded by the automatic computer controlled batching programme referenced to the asphalt docket issued. The temperature of final asphalt product shall be monitored and recorded in the daily docket and shall not exceed 180°C but not lower than 150°C. Plant Calibration It is the Production Engineer’s responsibility to ensure that all components of an asphalt plant are kept in calibration to reduce potential sources of assignable causes or non compliances. The components of the asphalt plant in Asphaltech, including weighbridge, aggregate scale, bitumen scale, hot mix storage weigh scale, RAP feeder scale and filler scale are scheduled to be calibrated annually. This calibration shall be maintained regularly as a part of Asphaltech’s quality control. In addition, the variable speed feed controller shall be calibrated annually in conjunction with aggregate bin gates and conveyors in-house to ensure the accurate feed rates. This activity shall be carried out every December or January when the aggregates are in a dry or nearly dry condition. Quality Assurance The testing of the asphalt product shall be carried out by a NATA endorsed laboratory in accordance with the minimum frequencies set out in the company Inspection Testing Plan. All tests shall be carried out in accordance with the current Australian and/or Main Roads WA standard.

Figure 7 Air Emission Points A3A.4 Emission / Discharge points

A3A.4.1 Emission Type: Air

• The main sources of airborne dust during the operation of the asphalt plant include: • Delivery and storage of raw materials. • Delivery and storage of filler materials. • Traffic movement on premises. • Dust from the pugmill and loading bay Specified emissions: particulate matter from the bag filter • Not more than 50 mg/m3 at any time.

Filtered air from the baghouse is to be released to the atmosphere through a 15m stack (includes cone). Daily visual monitoring maintained as per Environmental Log. Annual testing of the stack emissions are required through the DWER Licence, with those levels to be reported to the DWER annually. In the last three years of operation the levels for the Malaga Plant (the plant to be installed) the particulates ranged from 6.4 mg/m3 to 39 mg/m3, well under the requirement of 50 mg/m3 specified in the DWER Licence.

Aspect Impact Control Methods

Stack emissions from the plant

Dust discharged into the air The plant is serviced by a baghouse which minimizes dust emission via the stack.

The gases from the mixing tower that are mainly hot air with particulates from aggregates and gases from the dryer plant contain fines which are fed to the pre-separator for reprocessing.

Gases from the pre-separator enter the baghouse which consists of a serials of filters that capture any particulates (fines) which drop to the base and from there are recovered and sent to the imported filler silo and used in the asphalt.

The particulates stick to the bag filters, increasing the pressure which triggers automated cleaning procedures.

All recovered fines are used on site. The baghouse is inspected and maintained regularly. Annual stack emission testing conducted to conform to licence

requirements. Daily visual monitoring maintained as per Environmental

Log. Annual testing of the stack emissions are required through the DWER Licence, with those levels to be reported to the DWER annually. In the last three years of operation the levels for the Malaga Plant (the plant to be installed) the particulates ranged from 6.4 mg/m3 to 39 mg/m3, well under the requirement of 50 mg/m3 specified in the DWER Licence.

Daily visual monitoring is maintained as per Environmental Log.

Hardstand dust Traffic movement on premises

Dust may be generated from vehicle disturbance

Water will be available from the dam for dust suppression, drawn from the dam on site.

At the end of each daily production, or during if necessary, the hardstand is swept with a dedicated roller sweeper.

Hosing down is also used to remove and settle fines and dust. Perimeter screening bunds are in place and will be retained, as

will the screening trees to the west north and east. Yard surfaces are paved. Vehicle speed limit on the premises restricted to 5km, signage in

place. Regular sweeping of the premises conducted to prevent airborne

dust generation.

Dust from the storage bins

The raw feed storage bins have tall sides.

Aggregates are placed onto a firm floor which shall be at least level, or graded towards the face of the stockpile so that water does not settle on the floor and saturate the lower layers of the aggregate via capillary action.

The height of any raw materials storage is limited to the top of the wall to eliminate the possibility of spillage and reduce the possibility of wind-blown contamination or loss.

In dry, windy conditions, the Plant Operator is responsible for ensuring that wherever possible, the stockpile aggregate is kept damp by means of the automated “Cannon” sprinkler system to reduce wind-blown dust both from the surface of the stockpile and from the aggregate when being tipped into the cold feed bins.

Raw material available via onsite Hanson Quarry and from other sources. Vehicles will be fitted and use retractable covers to prevent airborne dust.

Raw material aggregates are sufficiently dampened when leaving the onsite quarry, prior to delivery to the storage bays.

Sprinkler systems are installed on the aggregate bays to maintain the materials in a damp state.

Stockpiles held in aggregate bays shall not exceed the height of the bay walls or extend past the sides of the bays to minimise airborne dust.

Traffic movement managed on premises with designated drive ways and signage.

Sweeping of yard is conducted when necessary, with special sweeper trucks fitted with misting spray bars and a suction sweeper to minimise airborne dust generation.

There remains a contingency to place a roof over the bins if required at some point in the future. This is not considered necessary at commencement because of the distance to sensitive premises.

The cold feed bins have high sides and a roof to minimise dust lift off from loading the bins.

The bins are installed with water sprays which are used to wet down materials as required.

Recovered asphalt pavement is also to be stored in a bin prior to reuse.

A3A.4.2 Emission Type: Stormwater

Figure 8 Stormwater Emission Point The only possibility of stormwater contamination may be caused from refuelling the loader by Contractor fuel suppliers and engine oil drips/spills from trucks and loader which is what may occur on any road surface. It is proposed that the Asphalt Mixing Plant will be positioned at a level R.L = 25.80m, whereby all stormwater runoff will be directed and drained to a proposed new Humeceptor (H) prior to entering the existing Dam water area (D) which is located some 100m South of the perimeter of the prescribed area and within part Lot 3(lease premises). Please refer to stormwater layout plan attached. All other areas of the prescribed area will drain naturally as they currently do. The existing DWER Licence has an emission point for stormwater and conditions that to be directed to an infiltration pond. On part lot 3 the water will be similarly contained but will not enter the groundwater system because it will be directed to the Humeceptor and then the dam, which is impervious and does not release water to the groundwater. Therefore there will be no risk of contamination of local surface water or groundwater. A copy of the details and construction of the proposed Humeceptor is attached. There is a high ground level area at the South – East Corner at the perimeter of the proposed prescribed premises which makes it a natural bunded area to prevent any stormwater runoff to the Dam further south. This natural bunded area will assist in directing all stormwater runoff to the Humeceptor.

Aspect Impact Control Methods The asphalt plant burner will operate on LPG

Gas

Refueling Loader and other vehicles

Minor Spillage Any diesel required, e.g loader, will be provided by an external fuel service vehicle.

A spill kit will be present on site. Any spill will be contained by the spill kit.

Staff will be trained in the use of the spill kit. Stormwater intersecting any spill area will be

directed to the Humeceptor. Hydrocarbons Contamination

Minor Stormwater runoff Humceptor installed. All surface water runoff is to be directed through

the Humeceptor. From there the water is directed to the Dam on Lot 3 which has no outlet and is used for dust suppression for the Gelorup Quarry and the Asphalt Plant.

The dam on Lot 3 currently accepts stormwater from the asphalt plant site which is located on the old Gelorup crushing and stockpile area and has stabilized between recharge and evaporation. No changes to the water level are anticipated.

Bitumen Storage Tank Potential issue from a leak in the tank.

The bitumen tank will be located in a lined impermeable bunded facility to ensure all leakages are contained.

Stormwater removed from the bunded facility is directed to the Humeceptor and then to the storage dam on the south of Lot 3.

The proposed asphalt operation, other than bitumen which will be bunded, will not have, on sit, any diesel, petrol or other hydrocarbons and therefore there is NO RISK to the land, soil and groundwater affecting the ecosystem. The asphalt plant burner will operate on LPG Gas and any diesel required, e.g loader, will be provided by an external fuel service vehicle.

A3A.4.3 Emission Type: Noise

Figure 9 Location of noise emission points The main sources of noise during the operation of the asphalt plant include: • Noise from fixed plant. • Noise from mobile plant. • On site traffic. • Truck traffic servicing the operations. • There is also the risk of umulative impacts from the quarry and the asphalt plant and therefore

noise measurements and modeling has been conducted by Asphaltech and Herring Storer. See the reports attached.

There is also the risk of cumulative impacts from the quarry and the operation of the asphalt plant and therefore noise measurements and modeling has been conducted by Asphaltech and Herring Storer Acoustics as outlined below.

Asphaltech Confidential | Page 19

Aspect Impact Control Methods Noise from fixed plant

Excessive noise levels on and offsite.

The plant components are fitted with noise reducing/silencing features. The burner fan is covered with a colorbond sheet. The air compressor is fitted with a sound proof cover. Cladding and insulation is fitted to exterior for durability and noise suppression. Noise testing is conducted on plant and machinery every five years as per the Code of Practice – Managing Noise at Workplaces.

Noise from mobile plant.

Excessive noise levels Mobile plant equipment regularly serviced and maintained to manufacturer’s specification. Equipment replaced regularly with latest new models meeting Australian Standards. Conduct noise testing on plant machinery every five years as per Code of Practice – Managing Noise at Workplaces.

External noise levels

Excessive noise levels on and offsite.

The proposed asphaltech plant previously operated in the Perth Metropolitan Area at Malaga. That plant has been disabled and is being moved to Lot 3 on the Gelorup Quarry Site. During operations in 2013 the noise levels of the various parts of the plant were measured and details are attached by Asphaltech. The relocated plant will be essentially the same with some improvements to the environmental management and therefore the noise pressure readings can be taken as a worst case scenario. The noise contours have been overlaid on the Gelorup site to show that noise impacts are managed and do not impact on local sensitive premises. See Asphaltech 2019, Noise Management Plan for proposed Asphalt Plant, Lot 3 Allenville Road, Gelorup. The closest dwelling to the asphalt plan is over 500 metres away. At that distance the predicted noise output was modeled to be 30.1 dB well within compliance of the Noise Regulations. The potential for cumulative impacts and truck traffic was considered in the Herring Storer Acoustic Study, dated June 2019. For that study Herring Storer used the measured data from the operating plant and combined them with the measured noise data from the operating Bunbury Quarry which has the same equipment as will operate at the Gelorup Pit. Herring Storer found that the combined noise of the asphalt plant and the Gelorup Quarry could easily comply at all dwellings. They also found that the truck activities would also comply, including accessing the asphalt during night time hours such as before 7.00 am when asphalt may be required for road and other construction. See Herring Storer, June 2019, Basalt Quarry, Asphalt Plant Lots 3 and 27, Allenville Road Gelorup, Acoustic Assessment.

A3A.4.4 Emission Type: Odour

The main sources of odour during the operation of the asphalt plant include:

• Bitumen Ventilation during hot bitumen transferring from road tanker to storage tank. • Hot Asphalt Discharge to Trucks at Pugmill This is the plant that was previously located at 416 Victoria Road, Malaga. Asphaltech has operated this plant in Malaga for 24 years. Refer to current Licence, Environmental Protection Act 1986, Part V:

• Licensee: Asphaltech Pty Ltd • Licence: L8447/2010/3

As such an analysis of the operation of that plant and the relocation to the new site on part Lot 3 have been assessed under the principles of the Department of Water and Environment Regulation Draft Odour Guideline for prescribed premises January 2018. The anaylsis of complaints, locations, wind patterns and the like, combined with a comparison to other operating sites, is prepared as a separate document and shows that there will be no increased risk from the commissioning of the plant on part Lot 3. A separate report on the potential for odour generation and nuisance has been prepared using the DWER Odour guideline for prescribed premises (Draft) January 2018. The analysis shows that the plant, when relocated, will be unlikely to cause any adverse impacts from odour generation. The plant operated for 24 years without complaint, even though there was significant light industrial land uses adjoining and nearby. The plant is being relocated to part Lot 3 at the Hanson Gelorup Quarry which has similar landform but much less dense adjoining land uses. The main risk is to the Gelorup Urban Area on still winter days. The meteorological data shows the number of calm days increases in winter to around 2.6 mornings per month. There are also times when the winds are light and another 15% or 3 days when gentle easterly winds are blowing. In winter therefore the number of calm days or light winds is around one working day per week when there is an increased risk of odour. Even so, with a buffer distance to the Gelorup Urban Area of 800 metres d it can be seen that only eight dwellings lie within the distance 800 – 1000 metres. There are three single dwellings to the north east and south – south west that lie within the same setback of 670 – 920 metres. All other dwellings lie outside 1 000 metres setback. In other directions the other four isolated dwellings are not in line of the prevailing winds.
