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 eleventh 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 February 2006 to 30 April 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

In February there were no exceedance of the AL or LL for TSP recorded during the reporting period. However, on the 16 March 2006, an exceedance of the AL for 1-hr TSP at the City Hall air quality monitoring station and an exceedance of the LL for 1-hr TSP at both the PLA and City Hall monitoring stations were recorded. On 25 April 2006, there were two exceedances of the AL for 1-hr TSP and one exceedance of the LL for 1-hr TSP recorded at PLA air quality monitoring station.

When the above TSP Exceedances were recorded, the general weather conditions on Hong Kong Island were very hazy with relatively low visibility. It is noted that Respirable Suspended Particulates (RSP) and API level recorded at EPD’s air quality monitoring stations in Central were also high. The weather and background air quality may have resulted in the exceedance of the AL and LL rather than the site activities which appear to be controlled, nevertheless the Contractor was reminded to suppress potential dust generation during the construction works to minimize possible.

Noise exceedances were recorded on the 6 and 20 February 2006 at City Hall but were not attributed to CRIII project works but more likely caused by a combination of noise sources including peak busy period traffic movements and other periodic sources that contributed to general background noise in the area.

One noise exceedances was recorded in March 2006 (i.e. on 3 March 2006) but was attributed to maintenance works being carried out by the ET on the SLM containment box. The exceedance at City Hall was, therefore, not attributed to CRIII project works.

During April 2006, two noise exceedances were recorded on the 19 and 20 April 2006, these were attributed to the Tian Hau Festival Activities, which included a boat moored on the Queens Pier broadcasting festive music. In the early hours of Monday the 24 April, two exceedances were recorded due to a thunderstorm. Further exceedances were recorded on the 28, 29 and 30 of April 2006. It was reported that a rally was held in the City Hall area between 28 April and 30 April 2006. The Contractor has also confirmed that there were no major project activities in the immediate vicinity of the City Hall during the above-mentioned days. In general, therefore, the exceedances at City Hall were not attributed to CRIII project works.

Normal DO levels were recorded in February 2006 along the seawall, in general, the majority of the stations showing levels within the AL although on a few occasions a few exceedances of DO and / or SS were reported. In March 2006 water quality along the seawall for most of the month was within the AL, however, the number of exceedances of the AL had increased slightly. During April 2006, DO levels along the seawall remained mostly within the AL, however, towards the end of the month DO levels began to fall.

Suspended Solid concentrations along the seawall were for the most part low during February 2006, although there were a few spikes which exceeded the AL. In March this pattern was repeated although the AL and / or LL was exceeded on a few occasions. During April SS levels were also for the most part low, although one spike in SS levels at one station did exceed the AL.

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

Particular precautionary mitigation measures implemented during this quarter included: commencement of Contractors Drainage Management Plan measures for the wet season, provision/renewal of four silt curtains inside culvert J, provision of a WetSep Water Treatment Plant, and improvement to Public Pier West Rock Socket Drilling spoil containment methods, as well as water bowsing to reduce dust generation.

Complaint Log

No new complaints were received during the reporting period.

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.

4. Environmental Complaint and Non-Compliance

4.1 Environmental E xceedances

In February there were No exceedance of the AL or LL for TSP recorded during the reporting period. However, on the 16 March 2006, an exceedance of the AL for 1-hr TSP at the City Hall air quality monitoring station and an exceedance of the LL for 1-hr TSP at both the PLA and City Hall monitoring stations were recorded. On 25 April 2006, there were two exceedances of the AL for 1-hr TSP and one exceedance of the LL for 1-hr TSP recorded at PLA air quality monitoring station.

During April 2006, two noise exceedances were recorded on the 19 and 20 April 2006, these were attributed to the Tian Hau Festival Activities, which included a boat moored on the Queens Pier broadcasting festive music. In the early hours of Monday the 24 April, two exceedances were recorded due to a thunderstorm. Further exceedances were recorded on the 28, 29 and 30 of April. It was reported that a rally was held in the City Hall area between 28th April 2006 and 30th April 2006. The Contractor has also confirmed that there were no major project activities in the immediate vicinity of the City Hall during the above-mentioned days. In general, therefore, the exceedances at City Hall were not attributed to CRIII project works.

DO levels recorded during February, March and April were for the most part in compliance with the AL. However, some exceedances of the AL were recorded and these are detailed below.

SS concentrations along the seawall were for the most part low during February, March and April 2006. However, a few exceedances of the AL and / or LL were recorded in February, March and April 2006, these are detailed below:

The exceedances observed were not directly attributable to project works as no marine works that would greatly disturb the seabed were being carried out during the reporting period and they are, therefore, attributed to natural variation in ambient conditions along the seafront and not project works.

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:
