Executive Summary

Atkins China Limited (ACL) has been appointed by TDD (now called the Civil Engineering and Development Department (CEDD) after the merger of the Civil Engineering Department and the Territory Development Department on 1 July 2004) to implement the Environmental Monitoring and Audit (EM&A) programme that was identified in the EIA Report for the CRIII Project and is providing Environmental Team services during the duration of the construction works.

This is the tenth 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 November 2005 to 31 January 2006.

Environmental Monitoring and Audit Progress

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

Exceedances of Action and Limit Levels

One air quality exceedance of the Action Limit (AL) for 1 hr TSP was recorded during the reporting period (December 2005). It was concluded that while works at CRIII may contribute in some way to the elevated levels observed, regional air quality was by far the biggest factor in the exceedance of the AL.

Continuous noise monitoring was carried out during the reporting period and noise exceedances were recorded in November 2005 (Total 1 Day), December 2005 (Total 1) and January 2006 (Total 12). The exceedances were found not to be attributed to the project works but rather to be a combination of the Hong Kong Electric’s Contractors laying a below ground cable directly in front of City Hall (November and December), the façade renovation works at City Hall (November 2005 to Mid January 2006), general peak bus and taxi traffic drop off flows in front of City Hall and Lunar New Year seasonal activities in January 2006.

Reduced DO levels were recorded in November 2005 along the seawall, the majority of the stations showing levels below the AL with only one exceedance of the Limit Level (LL). In December 2005 water quality along the seawall for the first part of the month was similar to that of November, showing several exceedances of the AL, however, as the month progressed overall DO concentrations increased. In January 2006, only one exceedance of the AL was recorded with most DO concentrations well above the AL.

While overall average concentrations of SS had reduced from the previous quarter, several exceedances of the AL and LL at the seawall stations were recorded for the reporting period. During November, SS levels exceeded the AL on 6 days and the LL on 2 days. During December 2005 SS was very low, with no exceedances being recorded. The general low concentration of SS was maintained in January 2006 although there were 3 days were SS concentrations spiked above the LL.

For both DO and SS these exceedances were not found to be attributable to the project works but rather natural variation in water quality across the site and beyond.

Precautionary mitigation measures implemented during the quarter included increased frequency of haul road water bowsing as a consequence of the dry season, coverage of stock piles, bunding of bore piling operations and installation of additional silt curtains in culvert J to prevent migration of silty water into Victoria Harbour.

Complaint Log

In December 2005, two noise complains were received one from a member of the public and one from the Management office for IFC both regarding construction noise along Man Yiu Street.

Notifications of Summons and Prosecutions

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

Site Inspection and Audit

Weekly environmental site inspections were carried out during this quarter. Any minor deficiencies noted during the site inspections were rectified by the Contractor upon receipt of notification.

On 16 January 2006, exceedances of the LL were recorded at stations M5 on the mid-flood tide.

On 25 January 2006, exceedances of the LL were recorded at stations M4A on the mid-ebb tide.

None of the observed WQ exceedances were found to be directly attributed to site works, as most of the major marine dredging and reclamation works for IRAE and IRAW have been completed, the remaining marine works undertaken during the period such as diversion works for culvert J and bore piling for the eastern seawall of FRAE did not result in significant disturbance to the seabed or creation of excessive suspended solids in Victoria Harbour.

A statistical analysis (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 generally did not cause adverse impacts during the reporting period with respect to the baseline condition.

4.2 Non Compliance

No environmental no-compliances were reported in the quarter.

4.3 Summary of Actions Taken by the Contractor

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

· General maintenance of bunds, drainage channels, catch-pits and wheel wash bays;

· Provision of rock and sand bunds along culvert J, IRAE;

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

· Drivers instructed to wash down truck wheels and undercarriage before leaving site;

· Water bowsing of haul roads and other areas of the site. Covering of stock piles.

4.4 Environmental Enquiries

No environmental enquiries were received during the reporting quarter.

4.5 Environmental Complaints and Prosecutions

A complaint was received by CEDD on the 12 of December 2005 from a member of the public regarding noise generated from works along Man Yiu Street. The Complaint was passed on to the ER and the ET for investigation.

In addition to the 24 hr noise monitoring carried out at City Hall by the ET, the ER also carry out ad-hoc noise monitoring twice a month on the IFC Podium (opposite Man Yiu St). Data from the IFC Podium indicate that Leq (30 min) dB(A) has remained below 70 dB(A) over the last 6 months.

The Environmental Monitoring and Audit (EM&A) Manual for CRIII sets out various noise control mitigation measures including the use of quiet plant and mufflers. These were installed on the excavation breaker so as to reduce further the nuisance to the public.

A response was issued by CEDD on the 18 of December 2005.

A complaint was received by CEDD on the 17 of December 2005 from the management office of IFC regarding noise generated from works along Man Yiu Street. The Complaint was passed on to the ER and the ET to investigate.

As discussed above, the ER carries out regular noise monitoring on the IFC Podium. In response to the complaint, the ET and ER carried out further noise monitoring during the noisiest activities at Man Yiu Street, daily 30 minute sheet piling works, and found that levels reached 72 Leq (30 min) dB(A).

The Environmental Monitoring and Audit (EM&A) Manual for CRIII sets out various noise control mitigation measures including the use of quiet plant and mufflers. Mufflers were installed on the excavation breaker so as to reduce further the nuisance to the office works.

As the IFC is a place of work relying on closed windows and due to the daily short period of sheet piling activity, the noise level threat at IFC should be lower than the 72 Leq (30 min) dB(A) measured on the Podium.

A response to the IFC Management Office was issued by CEDD on the 28 of December 2005.

4.6 Record of Environmental Complaints and Summons & Prosecutions
