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 1st July 2004.)

The works under the Contract HK 12/02 commenced on 28th 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 17th 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 26th 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 1st November 2009 to 31st January 2010.

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. 

Additional water quality monitoring was conducted, since 14th December, for the “the water quality of embayment area between the eastern seawall and the Hong Kong Convention and Exhibition Centre (HKCEC) upon completion of eastern seawall”, in accordance with the Environmental Permit No. EP-01/122/2003/D Condition 3.9. 

The water quality monitoring conducted by the ET was changed, as approved by EPD, since 11th January 2010, from 8 stations to 3 stations.

 

Exceedance of Action and Limit Levels

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

17 exceedance in noise level was recorded at the City Hall monitoring station on 9th, 11th and 12th November 2009, 5th, 6th, 14th and 31st December 2009 and 1st, 11th and 26th January 2010. On 9th, 11th and 12th November 2009, 6th, 14th and 31st December 2009 and 26th January 2010, the noise exceedances were considered to be attributed by the extension work on Hong Kong Planning and Infrastructure Exhibition Gallery rather than the project works. On 5th December 2009, activities East Asian Games opening ceremony which included firework display was carried out on the floating platform of Victoria Harbour. On 1st January 2010, a protest parade was held near the City Hall. On 11th January 2010, the major noise source during the monitoring period was Ceremonial opening of Legal Year 2010 which held in City Hall. 

Water quality exceedances were recorded on 14 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 also considered to have not been related to the Project works.
