Executive Summary

The Central Reclamation Phase III (CRIII) Works, Contract No. HK 12/02, was awarded to Leighton China State Van Oord Joint Venture (LCSVO-JV) by the Civil Engineering and Development Department (CEDD). (Previously called the Territory Development Department before merger with the Civil Engineering Department on 1^st July 2004.)

The works under the Contract HK 12/02 commenced on 28^th February 2003. Contract HK 16/03 for the CRIII Hinterland Drainage Improvement Works was awarded to Wang Kee Construction Co. Ltd., and works for this contract commenced on 17^th December 2003.

Atkins China Limited (ACL) has been commissioned by CEDD as the Environmental Team (ET) to undertake the Environmental Monitoring and Audit (EM&A) programme described in the approved EM&A Manual for the CRIII Project.

This is the 24^th quarterly EM&A Report for the works specified in Section 1.3 of the CRIII EIA Report. This report summarises the monitoring results and audit findings of the EM&A program during the reporting period from 1^st May 2009 to 31^st July 2009.

Environmental Monitoring and Audit Progress

Air quality, noise and water quality monitoring were conducted during this quarter. Weekly environmental site inspections were also conducted during this reporting quarter.

Exceedance of Action and Limit Levels

No exceedance in TSP level was recorded at the two monitoring stations during this reporting quarter.

No exceedance in noise level was recorded at the City Hall monitoring station during this reporting quarter.

Water quality exceedances were recorded on 34 sampling days in this reporting quarter. All exceedances have been investigated. All exceedances of Action/Limit Level for DO were considered to have not been related to the Project works. All exceedances of Action/Limit Level for SS were considered to have not been related to the Project works.

Complaint Log

There were no complaints received in relation to environment impact during this reporting quarter.

Notifications of Summons and Prosecutions

There were no notifications of summons or prosecutions received during this reporting quarter.

Environmental Observations

During the 12^th May 2009 environmental site inspection, EPD communicated with the ET and IEC that a report of muddy water near the works area of FRAE was received on 28^th April 2009. The report was relayed to the Contractor on 28^th April 2009.

After investigation by the Contractor, it was reported that the muddy water was due to a very high tide on the day (+2.4 mPD) which was higher than the concrete blocks, resulting in the detachment of some existing silt curtains and subsequent seepage of muddy water. An additional new curtain to enclose the seepage was being installed at the time of the observation, however the new curtain was not long enough to enclose the area. Further to this, an additional section of silt curtain was added on the same day (28^th April 09), providing appropriate enclosure of seepage. The area was monitored closely by the Contractor with no further issues noted

Site Inspection and Audit

Weekly environmental site inspections were carried out during this quarter. Minor deficiencies noted during the site inspections were rectified by the Contractor upon receipt of notification. The observations and findings are outlined below:

7^th May 2009

The access roads in IRAE and FRAW were observed dry with dust. The Contractor arranged for site staff to water the access roads appropriately.

Muddy water was observed near the mouth of culvert F. The source was identified as the piling activity in the works area of FRAW. Sediment was released from the seabed due to the piling works which could not be trapped by the silt curtain. The piling activity was stopped by the Site Supervisor immediately after such observation. The Contractor suspended the related works until the issue was resolved.

12^th May 2009

During the 12^th May 2009 environmental site inspection, EPD communicated with the ET and IEC that a report of muddy water near the works area of FRAE was received on 28^th April 2009. The report was relayed to the Contractor on 28th April 2009.

After investigation by the Contractor, it was reported that the muddy water was due to a very high tide on the day (+2.4 mPD) which was higher than the concrete blocks, resulting in the detachment of some existing silt curtains and subsequent seepage of muddy water. An additional new curtain to enclose the seepage was being installed at the time of the observation, however the new curtain was not long enough to enclose the area. Further to this, an additional section of silt curtain was added on the same day (28th April 09), providing appropriate enclosure of seepage.

A statistical analysis (presented in Annex I) of the suspended solids monitoring results found that the quarterly mean is significantly less than 1.3 times of the ambient mean recorded during the baseline period. This indicates that the Project construction works did not cause adverse impacts during the reporting period with respect to the baseline condition.

4.2 Non-Compliance

No non-compliance with regard to site environmental audit was recorded during the reporting period.

4.3 Summary of Actions Taken by the Contractor

The Contractor has implemented the following measures to prevent air and water quality impacts:

· Contractor has implemented their Drainage Management Plan to Control Site Run-off for the wet season – actions completed and underway include: repair and improvement of existing bunds/sandbags on the edge of the reclamation; installation of additional bunds; compaction of soil surface and paths where possible to prevent erosion, creation of drainage channels and soak pits;

· Provision of additional settlement tanks to remove suspended solids from discharge waters;

· Provision of catch pits to collect spill over from wheel washing facilities and increased frequency of cleaning of catch-pits; and

· Water browsing of haul roads and other areas of the site and covering of stockpiles.

4.4 Environmental Enquiries

No environmental enquiries were received during this reporting quarter.

4.5 Environmental Complaints and Prosecutions

No environmental complaints were received during this reporting quarter.

4.6 Environmental Observations

During the 12^th May 2009 environmental site inspection, EPD communicated with the ET and IEC that a report of muddy water near the works area of FRAE was received on 28^th April 2009. The report was relayed to the Contractor on 28^th April 2009.

After investigation by the Contractor, it was reported that the muddy water was due to a very high tide on the day (+2.4 mPD) which was higher than the concrete blocks, resulting in the detachment of some existing silt curtains and subsequent seepage of muddy water. An additional new curtain to enclose the seepage was being installed at the time of the observation, however the new curtain was not long enough to enclose the area. Further to this, an additional section of silt curtain was added on the same day (28^th April 09), providing appropriate enclosure of seepage. The area was monitored closely by the Contractor with no further issues noted

4.7 Record of Environmental Complaints and Summons & Prosecutions

There was no record of environmental complaints during this reporting quarter.

There were no notifications of summons and prosecutions during this reporting quarter.

5. Conclusion

During the environmental site inspections conducted within this reporting quarter, no non-compliances were noted and no prosecutions were received during this reporting quarter.

No exceedance in TSP level was recorded at the two monitoring stations during this reporting quarter.

No exceedance in noise level was recorded at City Hall monitoring station during this report quarter.

Water quality exceedances were recorded on 34 sampling days in this reporting quarter. All exceedances have been investigated. All exceedances of Action/Limit Level for DO were considered to have not been related to the Project works. All exceedances of Action/Limit Level for SS were considered to have not been related to the Project works.
