In addition, the IEC shall be responsible for verifying the environmental acceptability of permanent and temporary works, relevant design plans and submissions under this Permit. The IEC shall verify the log-book(s) mentioned in Condition 2.1 of this Permit. The IEC shall notify the Director by fax, within one working day of receipt of notification from the ET Leader of each and every occurrence, change of circumstances or non-compliance with the EIA Report (Register No. AEIAR-055/2002) or this Permit, which might affect the monitoring or control of adverse environmental impact. Where the IEC fails to so notify the Director of the same, fails to discharge the duties of the IEC as defined the EM&A Manual or fails to comply with this Condition, the Director may require the Permit Holder by notice in writing to replace the IEC. Failure to replace the IEC as directed or further failure to so notify the Director despite employment of a new IEC may render the Permit liable to suspension, cancellation or variation.

After the full completion of the dewatering activities, confirmation tests shall be conducted at the locations of the soak away pit and the wastewater storage facility to verify that there is no land contamination caused by the dewatering activities. If contaminated soil is found, it shall be collected and treated in accordance with the requirements of the Remediation Plan approved under Condition 2.7 of this Permit.

3.14 Excavation of dioxins contaminated soils shall be limited to 200 m³/hr. Excavation of styrene and chromium VI contaminated soils shall be limited to 20 m³/hr.

The locations of contaminated soils as identified in the EIA report are shown in Figure 4 of this Permit.

3.15 Excavated soils shall be loaded directly onto vehicles for transportation of contaminated soils at the point of excavation to avoid stockpiling of contaminated soils and minimise double handling and any associated loss.

3.16 After excavation, confirmation sampling and testing shall be conducted in accordance with the Remediation Plan as described in Condition 2.7 of this Permit to ensure complete excavation of contaminated soils.

3.17 Handling process of contaminated soils such as screening and crushing shall be conducted in an roofed and sheltered environment which shall be bottom lined with concrete or impermeable sheet.

Measures for Transportation of Contaminated Soils from CLS Site to TKW Site

3.18 All contaminated soils which require to be transported from the CLS site to the TKW site shall be transported via a dedicated road access as shown in Figure 5 of this Permit to minimise interface with public road. No other transportation route shall be used unless otherwise agreed with the Director. The entire dedicated road access shall be properly illuminated if there are any night works.

Action Levels and Cleanup Targets for Land Remediation

3.19 Land decontamination works of the Project shall be carried out to comply with the action levels as described in Appendix A of the Permit and the cleanup targets as described in Appendix B of this Permit. The action levels and cleanup targets for dioxins are 1ppb I-TEQ for soils that will be left or placed below 3m of clean fill; and 0.1ppb I-TEQ for soils that will be left or placed from ground surface to 3m deep.

Measure for Treatment of Non-Dioxin Contaminated Soils

3.20 Soil contaminated with Total Petroleum Hydrocarbons (TPH) and/or Semi-Volatile Organic Compounds (SVOCs) only shall be treated by biopiling method at the TKW site.

3.21 Soil contaminated with metals and TPH / SVOCs shall be treated by biopiling method for organic contaminants and followed by cement solidification for metal contaminants at the TKW site.
