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 23^rd 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 February 2009 to 30^th April 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.

35 exceedances in noise level were recorded at the City Hall monitoring station during February 2009 of the reporting period. Based on the observation and Contractor record, drilling and sheet piling activities were being undertaken in the works area of the former Queen’s Pier during the monitoring period. Therefore, the exceedances may have been attributed to the Project works, possibly due to the concurrent operation of both the drilling and sheet piling activities.

ET communicated exceedances to the Contractor representative accordingly and it was suggested that the Contractor schedule the construction activities at the former

Queen’s Pier carefully and that concurrent operation of both the drilling and sheet piling activities should be avoided. Following three such notifications, a meeting was scheduled and held on 2nd March 2009 at 14:00 with ET, Contractor representative, RE and IEC in attendance where the noise exceedances were discussed along with further mitigation measures.

Further mitigation measures were carried out, whereby the Contractor representative provided guidelines to frontline staff to continue with previous guidelines and to also stagger lunch breaks to avoid such exceedances. Furthermore, additional noise mats were installed at existing noise barrier. A review of noise data from 14:05 on 27^th February to 5th March 2009 showed that no further noise exceedance occurred.

On 23rd February 2009, there were maintenance works on the box containing the sound level meter. As such, the noise exceedances on this day are considered to be attributed to the maintenance works rather than the project works.

Water quality exceedances were recorded on 30 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.

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:

5^th February 2009

A stockpile was observed without cover near P2 roads work area in IRAE. The contractor was reminded to cover stockpiles when unused.

12^th February 2009

N.A.

19^th February 2009

N.A.

26^th February 2009

· Dark smoke emission was observed from the air compressor in the FRAW works area. The Contractor was reminded to maintain and inspect equipment appropriately to prevent smoke emission.

· Muddy water was found on the caisson surface near the mouth of Culvert J and brownish water was also observed near the mouth of Culvert J. The investigation revealed that the muddy water was due to the unloading of materials from the barge during the morning of 26th February 2009. The Contractor was reminded to prevent material leakage during barge unloading.

5^th March 2009

N.A.

12^th March 2009

· Rubbish was trapped by the silt curtain in the culvert F. The Contractor was reminded to collect rubbish at culvert F regularly.

· The additional silt curtains installed at the sea opening in FRAW were not installed appropriately. The Contractor was reminded to install and maintain the additional silt curtains at the sea opening in FRAW appropriately to ensure efficient functioning.

20^th March 2009

2^nd April 2009

· A patch of contaminated soil was observed in the work area of CR16 due to relocation of a generator. The Contractor was reminded to collect and dispose of the contaminated soil as chemical waste.

· Drums containing chemicals were stored without drip trays in the works area of Tun Wo Lane. In addition, runoff (of water which was clear at the time) was discharged without the use of a sediment tank. The Contractor was reminded to provide drip trays for temporary chemical storage in the works area and also to provide sediment tanks for discharge from the works area. The Contractor stopped the works at Tun Wo Lane in order for implementation of a sediment tank.

· Silt was observed on the public road at the site entrance on Man Yiu Street. The Contractor was reminded to ensure that all vehicles leaving the site should utilise the wheel washing facility appropriately.

9^th April 2009

· Some general refuse including wood material was observed in the works area at IRAE. The Contractor was reminded to collect refuse regularly and to ensure site tidiness.

· A container of unidentifiable liquid was found near the access road of IRAE. The Contractor was reminded to treat and dispose of the container of unidentifiable liquid as chemical waste.

· Muddy water was observed upstream of Culvert F which may be caused by the excavation work in the region. However, no muddy discharge was observed at the mouth of culvert F at Victoria Harbour. The Contractor was reminded to prevent muddy discharge from the site and to provide enough silt curtains in the culvert for precaution.

16^th April 2009

Muddy water was observed at Victoria Harbour near Pumping Station 7.1. This was observed on the outside of the site boundary, exterior to the silt curtain on the mouth of culvert F. However, no muddy water was observed on the inside of the site boundary, interior to the silt curtain. The source of the muddy water was unidentifiable after investigation by the Contractor, IEC and ET during the inspection, and had disappeared before the end of the inspection. The Contractor was reminded to closely monitor the situation and to ensure that no muddy water is discharged to Victoria Harbour from the site. The Contractor has arranged frontline staff for such monitoring.

23^rd April 2009

Dark smoke emission was observed from the air-compressor in the FRAW works area. The Contractor was reminded to maintain and inspect equipment appropriately to prevent dark smoke emission

30^th April 2009

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.
