Employment of Environmental and Audit (EM&A) Personnel
2.1 An Environmental Team (ET) shall be established by the Permit Holder no later than one month before the commencement of construction of the Project. The ET shall not be in any way an associated body of the Contractor or the Independent Environmental Checker (IEC) for the Project. The ET shall be headed by an ET Leader. The ET Leader shall be a person who has at least 7 years of experience in environmental monitoring and auditing (EM&A) or environmental management. The ET and the ET Leader shall be responsible for the implementation of the EM&A programme in accordance with the EM&A requirements as contained in the EM&A Manual of the Project. The ET Leader shall keep a contemporaneous log-book of each and every instance or circumstance or change of circumstances, which may affect the compliance with the recommendations of the EIA Report (Register No. AEIAR-123/2008) and this Permit. The ET Leader shall notify the IEC within one working day of the occurrence of any such instance or circumstance or change of circumstances. The ET Leader’s log-book shall be kept readily available for inspection by all persons assisting in supervision of the implementation of the recommendations of the EIA Report (Register No. AEIAR-123/2008) and this Permit or by the Director or his authorized officers. Failure to maintain records in the log-book, failure to discharge the duties of the ET Leader as defined in the EM&A Manual or failure to comply with this Condition would entitle the Director to require the Permit Holder by notice in writing to replace the ET Leader. Failure by the Permit Holder to make replacement, or further failure to keep contemporaneous records in the log-book despite the employment of a new ET Leader may render the Permit liable to suspension, cancellation or variation.
2.2 An IEC shall be employed by the Permit Holder no later than one month before commencement of construction of the Project. The IEC shall not be in any way an associated body of the Contractor or the ET for the Project. The IEC shall be a person who has at least 7 years of experience in EM&A or environmental management. The IEC shall be responsible for duties defined in the EM&A Manual, and shall audit the overall EM&A performance, including the implementation of all environmental mitigation measures, submissions required in the EM&A Manual, and any other submissions required under this Permit. 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-123/2008) and this Permit, which might affect the monitoring or control of adverse environmental impacts from the Project. In the case where the IEC fails to so notify the Director of the same, fails to discharge the duties of the IEC as defined in 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. Notification by the Permit Holder is the same as notification by the IEC for the purpose of this Condition.
Management Organization of Main Construction Companies
2.3 The Permit Holder shall, no later than two weeks before the commencement of construction of the Project, inform the Director in writing the management organization of the main construction companies and/or any form of joint ventures associated with the construction of the Project. The submitted information shall include at least an organization chart, names of responsible persons and their contact details.
Measures for Mitigating Ecological Impact
2.4 To mitigate the ecological impact on the Common Rat Snake Ptyas mucosus, capture-surveys on the species shall be conducted by a qualified ecologist within the project site before the commencement of construction of the Project. Any of these species caught during the surveys shall be relocated to nearby shrubland or other suitable habitats to be agreed by the Director. The Permit Holder shall, within one month after completion of capture-survey and relocation works, deposit with the Director three hard copies and one electronic copy of the report including the following information :-
(a) qualification of the ecologist(s) to carry out the capture-survey and relocation works;

Environmental Permit No. EP-388/2010
環境許可證編號EP-388/2010
Annex A (as referred to in Condition 3.10)
Measures to Mitigate Water Quality Impact During Construction
(i) Surface run-off from the construction site shall be directed into adequately designed sand/silt removal facilities such as sand traps, silt traps and sediment basins before discharge into storm drains. Channels, earth bunds or sand bag barriers shall be provided on site to properly direct stormwater to such silt removal facilities.
(ii) Catchpits and perimeter channels shall be constructed in advance of site formation works and earthworks.
(iii) Manholes (including newly constructed ones) shall be adequately covered and temporarily sealed so as to prevent silt, construction materials or debris being washed into the drainage system.
(iv) Silt removal facilities, sediment traps, channels and manholes shall be suitably maintained with the deposited silt and grit being removed regularly at least once a week, and at the onset of and after each rainstorm to ensure that these facilities are functioning properly at all times.
(v) Earthworks final surfaces shall be well compacted and the subsequent permanent work or surface protection shall be carried out immediately after the final surfaces are formed to prevent erosion caused by rainstorms. Appropriate intercepting channels shall be provided along the site boundary. Rainwater pumped out from trenches or foundation excavations shall be discharged into silt removal facilities before discharge into storm drains.
(vi) Open stockpiles of construction materials (e.g. aggregates and sand) on site shall be covered with tarpaulin or similar fabric during rainstorms. Measures such as providing sand bag barriers shall be taken to prevent the washing away of construction materials, soil, silt or debris into any drainage system.
(vii) All generators, fuel and oil storage shall be within bunded areas. Drainage from the areas shall be connected to storm drains via a petrol interceptor, which should be regularly emptied to prevent the release of oil and grease into the storm water drainage system.
(viii) The excavation works for the drainage diversions shall be carried out during low tide or under a condition that seawater influx entering the works area can be minimized to keep the works area dry.
(ix) The dredging / sandfilling works shall not cause the release of foam, oil, grease, litter or other objectionable matter into the water within and adjacent to the Project site.
(x) Adequate clearance between vessels and the seabed shall be maintained at all time to avoid water pollution due to turbulence from the vessel movement or propeller wash.
