2.0 INTRODUCTION

2.1 Background

Cleartech Waste Management Pty Ltd (CWM) is a private waste management business established in 2006.

The director and employees of the company have extensive experience within the waste management and

environmental services industry in Western Australia, Australia and Europe including significant experience

at senior management and board level in both public and private businesses. CWM has successfully been

operating a waste transfer facility (WTF) at Units 3 & 4 390 Victoria Road (CTS) since 2016.

Cleartech Waste Management Pty Ltd proposes to operate a larger waste transfer facility which will receive

packaged controlled wastes from Perth and Western Australian industry primarily manufacturing, oil &

gas, mining, government, healthcare and automotive industries. Waste materials to be received at the

facility include paints, resins, hydrocarbons, solvents, batteries, oils, greases and other controlled wastes. A

full listing of the waste types and volumes is provided later in this document.

Volumes of industrial wastes in Western Australia continue to increase year on year with the continued

expansion of mining and oil & gas sectors and associated support industries. Waste producers continue to

strive for better environmental outcomes to minimise the impact of their operations. Cleartech has been

established to provide technical solutions for difficult or problematic industrial wastes produced by West

Australian industry and to manage them in a safe and sustainable manner maximising reuse and recycling over

traditional treatment and disposal options.

The WTF will receive both bulk and packaged controlled waste which will be inspected, assessed, processed,

consolidated then stored pending despatch from the facility to approved re-use, recycling and disposal facilities in

Western Australia, Australia and potentially overseas.

It is expected that the WTF will have an initial throughput of approximately 5000 tonnes per annum which will

increase up to a design capacity of 10,000 tonnes per annum over five years. At any time the facility will hold

no more than 300 tonnes, will comply with any relevant Australian Standards and hold all the necessary

approvals including dangerous good storage if required.

Benefits that this development will provide include;

• Location and Logistics

• Enhanced Recovery

• Existing Facilities at Capacity

Location and Logistics

The Malaga based facility is strategically located to service industry in the north and east of Perth and is General

Industry zoned. Its location is ideal not only to service the expansion of industry in the northern suburbs of Perth

but also those in Welshpool and Canning Vale. The facility shall provide essential waste management

infrastructure and satisfies the proximity principle by serving these growing industrial areas.

The facility is also well situated with regard to transport links with the Mitchell Freeway and Tonkin Highway

with other major haulage roads readily accessible.

6


Enhanced Recovery With the specialist knowledge and experience of the director and employees of Cleartech the intent of this

facility will be to provide viable reuse and recycling routes for our client's wastes where applicable.

Existing Facilities at Capacity

In addition to the proximity and logistical benefits to waste generators in the North and North-East of

Perth, there is benefit to providing additional waste management capacity to the Perth and Western

Australian region as a whole. Anecdotally, there is evidence that existing facilities both South and

East of the city have been reaching capacity limits and restricting their intake of waste as a result of

the increased volumes being produced as a result of growth in the region on the back of major

construction projects in Perth and the North-West. This bottle-necking of waste disposal could lead

to inappropriate disposal locations or methods being used by some unscrupulous operators.

Waste Types Accepted

The WTF will be licensed to accept all categories of controlled waste as per the Environment

Protection Act (controlled waste) Regulations 2004. The inputs associated with the proposed waste

management transfer facility are outlined in Section 3.0

3.0 PROPOSAL DESCRIPTION

3.1 Overview

CTS proposes to operate a waste transfer facility (WTF) for the acceptance, consolidation, storage and

transfer off-site of bulk and packaged controlled wastes. We also propose to do a small amount of

treatment to chemical waste. Activities on site shall include;

• Controlled waste receipt and storage;

• Controlled waste consolidation and storage;

• Chemical treatment and absorption/immobilisation of limited types of waste

• Controlled waste transfer to approved recycling, treatment and/or disposal facilities by road transport;

Infrastructure associated with this facility shall include: • Packaged waste stores

• Vehicle unloading area

• Waste receipt, inspection and sorting area

• Chemical treatment and absorption/immobilisation

• Bin storage area

Cleartech Waste Management propose to store liquid controlled wastes within low permeability bunded

areas that allow the recovery of liquid in the event of spillage. For liquid waste stored in packages, the

capacity of the spill containment compound is at least 100% of the volume of the largest package plus 20%

of the storage capacity up to 10,000L, together with 10% of the storage capacity between 10,000L and

100,000L and 5% above 100,000L.

The bunded areas within the premises will meet the requirements described below;

• Be chemically resistant to the substances store;

• Be designed such that chemical which may react dangerously if they come into contact, are in

separate bunds in the same compound or in different compounds;

• Be controlled such that the capacity of the bund is maintained at all times

12


3.2 Forecast Waste Types & Volumes

Table 4 provides indicative volumes of waste the facility can be expected to receive over the next 3 years . The waste types accepted on site will include all categories of controlled waste however the main waste types have been grouped together for the purpose of this table.

3.3 Operating Hours

The normal operating hours of the facility will be:

• Office: 7:30am to 5:00pm

• Transfer Facility: 7:00am to 5:00pm

The nature of this industry however necessitates the ability from time to time to operate on a 24 hour,

7-day per week basis, however, this will only be on an as required basis.

13


3.4 Waste Acceptance Procedure

All waste materials will be assessed prior to quotation and collection following documented health, safety,

environmental and quality (HSEQ) procedures and Environmental Protection (Controlled Waste)

Regulations 2004. Upon receipt all materials will be inspected and assessed to ensure compliance prior

to processing and storage pending off-site transfer for re-use or disposal.

The main stages and control documents in this process include:

Waste assessment & evaluation form (includes analysis and MSDS as appropriate)

• Job Sheet & manifest

• Company Quotation and Conditions

• Controlled Waste Tracking Form

• Waste or Dangerous Goods Transport Document (if applicable) & labels

• Waste Acceptance Form

• Site Inspection Checklist

All stages of the assessment, quotation, collection, receival, processing and dispatch are monitored and

audited as part of the company 's HSEQ management system.

3.5 Description of Operations

Waste Types & Classification

The facility will be licensed to accept all controlled waste categories Indicative waste types and volumes

have been provided as part of this submission section 3.2. The facility will accept both packaged and bulk

controlled wastes.

Delivery Method

It is anticipated that waste will be delivered by flat deck vehicles or curtain-sided vehicles and vacuum/bulk

tanker and the average load size will be less than 10 tonnes.

Each waste load received will be inspected and assessed prior to unloading in the designated unloading area.

Once received the waste will then be placed into an inspection and processing area (if packaged) or transferred

to a holding tank (if bulk) awaiting a more detailed assessment prior to allocation of storage and off-site dispatch.

Dispatch Method

Packaged waste will be dispatched by site via road transport in loads sizes typically between 10 to 20 tonnes.

Bulk wastes shall be dispatched from site via road transport in loads typically between 10 and 20 tonnes in

vacuum or bulk liquid tankers.

All controlled waste dispatched from site shall be via controlled waste licensed vehicles.

14


Storage of Waste

Once waste received on site is assessed and consolidated/aggregation it shall be allocated a storage

bay appropriate to its characteristics. The site will have the following segregated storage areas:

Combustible Liquids (hydrocarbons)

Non-Hazardous Solids & Liquids

Flammable Solids & Liquids

Corrosive Solid & Liquids

Oxidising Solids & Liquids

Environmentally Hazardous Solids & Liquids

Toxic Solid & Liquids

Table 5 below gives an indication of the expected types & volumes of waste to be held on site at any

time along with the respective capacities on site for that waste category.

Table 5 - Site Storage Volumes and Locations

Category Expected Quantity

Container Type Location Capacity

Combustible <5 Tonnes Package Non-DG Storage area 10 Tonnes

Non Dangerous <10 Tonnes Package Non-DG Storage area 20 Tonnes

Flammable <5 Tonnes Package DG Storage area 3 20 Tonnes

Corrosive <5 Tonnes Package DG Storage area 8 10 Tonnes

Oxidising <1 Tonne Package DG Storage area 5 2 Tonnes

Environmentally Hazardous

<2 Tonnes Package DG Storage area 9 5 Tonnes

Toxic <2 Tonnes Package DG Storage area 6 5 Tonnes

All packaged waste will be stored in compliance with the relevant Australian Standards and Codes of Practice for the storage of Dangerous Goods. The expected quantity is the normal operating volumes expected to be stored at the facility. Volumes of waste on site will be managed to ensure sufficient capacity at all times.

All packaging received on site will either be:

Reused - in the event any waste is delivered to site in a reusable container all efforts to return the container to the customer or to reuse the container will be made Recycled - wherever possible empty containers shall be drained and/or cleaned to be free of residue and recycled. Disposed - Containers and packaging that is not reusable or not residue free will be incorporated into landfill waste for disposal as appropriate.

15


3.6 Waste Processing

The predominant form of processing on-site will be the consolidation of smaller packaged waste

(<200 litres) volumes into larger containers to facilitate the safe, environmentally efficient and

operationally effective manner of shipment off-site for re-use, recycling or disposal.

Once waste is received and accepted on site it will be assessed by technically qualified personnel and will

then be processed according to the following criteria:

• Physical Form

• Hazard - reactivity, flammability, acidity etc.

• Waste type & contaminants

• Package quality , size and type

Similar waste streams are assessed and compatibility checked to ensure suitable for consolidation

prior to transfer of contents into 200 and 1,000 litre containers. Liquids will be transferred via gravity

discharge, vacuum or compressor driven air pumps.

3.7 Chemical Treatment

Smaller selected waste streams will be treated on site. Treatment processes will include:

• Oxidation - Reduction (REDOX) neutralisation

• Acid – Base neutralisation

• Absorption of small quantities i.e. <1 tonne per week of non-reactive liquid/sludge waste such as herbicides, pesticides, drilling mud, laboratory samples, oil sludge, etc. Disposal of absorbed material will be to class 2 landfill.

Neutralised/treated liquid waste will then be consolidated and sent for disposal as per the processes

described in section 3.6, above.

3.8 Waste Dispatch

Once packaged wastes have been aggregated into suitable loads for dispatch, this is typically 10 to 20

tonnes in size however can be less depending on the nature of the material. The aggregated waste

is dispatched to approved reuse, recycling, treatment or disposal facilities both within Western

Australia , other states in Australia and potentially overseas.

All controlled wastes greater then 200kg dispatched from the facility will be tracked as per the

Environmental Protection (Controlled Waste) Regulations and additionally any waste sent inter-state

would be accompanied by the required interstate waste movement approvals as regulated by the

National Environment Protection Measure (NEPM) for inter-state waste movements. Any waste

materials requiring to be sent overseas for recycling will be accompanied by the appropriate Federal

approvals as per the Basel Convention.

16


3.9 Description of Project Infrastructure

The general infrastructure required is already in place and includes:

• Sealed roadways

• Utilities - water, power, telecommunications

• Stormwater control systems and site drainage

• Covered operational and storage areas

• Concrete loading, storage and processing areas

7.0 ENVIRONMENTAL IMPACTS & MITIGATION MEASURES

7.1 Introduction

A qualitative Environmental Risk Assessment (ERA) has been undertaken to:

• Identify the type of impact (hazards) associated with the proposed operation;

• Analyze the probability (likelihood) and significance (consequence) of the impacts occurring to

determine the level of the risk;

• Evaluate the impacts to assess the extent and nature of management required;

• Identify and assess mitigation measures to determine the best management options to

mitigate impacts; and

• Determine the level of residual risk following the implementation of mitigation measures.

7.2 Methodology

The ERA has been prepared in accordance with Australian Standard AS 4360 Risk management Guidelines, 2004 (AS4360-2004) . The risk management process is illustrated as follows:

Figure 7 - Risk Management Process (Standards Australia, 1999)

21


The following aspects I receptors have been assessed as part of the ERA:

• Air Quality (Dust and Odor);

• Noise and Vibration ;

• Water Quality (Surface Water and Groundwater);

• Soil;

• Flora and Fauna;

• Weeds and Feral Animals;

• Culture (Aboriginal and European) and Heritage ;

• Waste Management (Solid and Liquid Waste) ;

• Health and Safety Management;

• Traffic Management; and

• Dangerous Goods.

The definition of risk according to AS4360-2004 is "the chance of something happening that will have an impact on objectives ". The assessment of risk is a factor of the likelihood of an impact occurring and the consequences of the impact occurring in relation to a particular receptor. The combinat ion of these aspects will determine the level of risk of the impact.

The following tables outline the criteria that have been used to assess the likelihood and consequences of potential impacts occurring for the proposed operation. Potential impacts have been assessed for operational phase of the project.

The likelihood of an impact arising is defined in Table 7. The likelihood relates to the probability of a potential hazard I impact occurring.

Table 6 - Likelihood (Probability) Scale

Category Description Score

Almost Certain

Is expected to occur in most circumstances. Almost certain or the most likely and expected result. Has a >90% chance of occurring if the risk is not mitigated.

10

Likely Will probably occur in most circumstances. Quite possible I not unusual. Has a 60-90% chance of occurring if the risk is not mitigated. 6

Possible Might occur at some time. Would be a remotely possible coincidence. Has a 40- 60% chance of occurring if the risk is not mitigated. 3

Unlikely

Could occur at some time. Would be remotely possible coincidence. Has a 10- 30% chance of occurring if the risk is not mitigated. 2

Rare May occur only in exceptional circumstances. Less than 10% chance of occurring if the risk is not mitigated. 1

>90-200 Extreme Immediate action is required. Appropriate measures are to be developed to mitigate and manage the potential impacts associated with risks.

>20-90 High Management / long-term risk reduction is required. Appropriate measures are to be developed to mitigate and manage the potential impacts associated with risks.

>6-20 Medium Management of risks is required. Risks can be mitigated by implementing reasonable / standard management measures.

0-6 Low

Acceptable risks are assessed and controlled as required. No specific management measures are required or risks can be directly managed through design measure, general mitigation measures and safety controls.

The risk rating for potential impacts assumes that no management I mitigation measures will be put in place and determines the inherent (uncontrolled) risk. Mitigation measures have been recommended for potential impacts and the risk rating revised to determine the level of residual risk remaining, following the implementation of these measures.

Mitigation measures have been identified in accordance with hierarchy of control measures as follows:

• Elimination - Eliminate the hazard from the project altogether (i.e. eliminate a hazardous task that is not required);

• Substitution - Replace a process with a less hazardous one;

• Isolation - Isolate the hazard from receptors through the use of barriers etc.;

• Engineering - Redesign work procedures I processes to reduce the hazard;

• Administrative - Provide construction workers with training, instruction, supervision, job rotation and safe work procedures to prevent impacts I incidents.
