1. ENVIRONMENTAL MANAGEMENT PLAN

A plan which details the following information regarding the use of restricted Category C cover material at Taylors Road Landfill;

• A risk assesment

• Operational procedures

• Monitoring Program

What is it?

3

RISK ASSESSMENT

• The risk assessment was conducted as per the relevant sections of EPA publication 1321.2 (2011) – Licence Assessment Guidelines

• The methodology used required identification of the following;

– Receptors

– Pathways

– Emissions• Once these are identified, each item is looked at individually and

assigned a level of risk based on no controls.• An review into existing controls and other data (historical monitoring,

precedent, likelihood etc) is conducted and a reviewed risk rating is applied.

What is this and how was it done?

RISK ASSESSMENT

The table in Appendix 5 summarises the Risk Assessment process.

OPERATIONAL PROCEDURES

• This section of the EMP details the operational methods and controls regarding the use of Category C soil as cover material;

– Restricted contaminants

– No double handling

– Dust mitigation as required

• These controls & procedures are derived from the risk assessment and address the identified risks.

• These operational procedures are what control the level of risk associated with the activity.

What is this and how was it done?

6

MONITORING PROGRAM

• Monitoring data will is used to measure whether the operational procedures are being effective in controlling the identified risks.

• As the predominant risk identified with the Category C cover trial is in relation to airborne dust and contaminants, the monitoring program in this management plan focuses on assessing these risks.

Why is this important?

7

MONITORING PROGRAM

• Daily visual post placement inspections of restricted Cat C cover by SITA staff, prior to close of business.

• VOC monitoring within the PIW cell to be conducted by SITA staff with the use of appropriate equipment.

• Ammonia monitoring within the PIW cell to be conducted by SITA staff with the use of appropriate equipment

• Directional dust monitoring gauges assessed by a third party NATA-accredited laboratory.

• Weather conditions (specifically wind)

What will it consist of? What is being monitored?

8

MONITORING PROGRAM

• 24 hour dust and contaminant monitoring events (including monitoring during non-operational periods)

• Conducted by a third party NATA-accredited consultant and laboratory with use of specialised equipment

• Assesses levels of dust being emitted from the PIW cell over 24 hours (operational & non-operational)

• Considers the impact of the weather conditions (wind, temperature, rain, etc)

• Assesses for contaminants within the restricted Cat C cover range such as metals, as well as for asbestos.

What will it consist of? What is being monitored?

9

AUDITOR REVIEW

• All monitoring results will be provided to the auditor as they are received by SITA during the trail period

• This does not mean any required action will not be taken until auditor review.

• At the conclusion of the trial period, the auditor will provide a report with an assessment on the use of Cat C cover and the results of the trial period.

How is the auditor involved in the process?

10

• an EMP has been developed

• Risk assessments have been conducted to BPEM standards

• Operational procedures have been developed

• Monitoring processes have been defined

• an independent Auditor will review
