5.                    CONCLUSION AND RECOMMENDATION

5.1                    Conclusions

5.1.1                1-hour TSP and 24-hour TSP impact monitoring at AMS2, AMS3C and AMS7B were carried out in the reporting period, no Action / Limit Level exceedance was recorded during the period.

5.1.2                Summary of Action and Limit Level exceedance of 1-hour TSP level and 24-hour TSP level at AMS6 shall be referred to the monthly EM&A report prepared by Contract No. HY/2011/03.

5.1.3                Construction noise monitoring were carried out in the reporting period, no Action / Limit Level exceedance was recorded during the period.

5.1.4                In accordance with the Dolphin Monitoring Survey Findings and Analysis in Section 3.3.9 and 3.3.10 of Appendix I, low dolphin occurrence of dolphins within the survey areas in both NEL and NWL were observed during the construction period. Moreover, such significantly and dramatically decrease of dolphin usage in those area has also been observed in this reporting quarter. In addition, the dolphin usage in North Lantau water has not only shown no sign of recovery, but also has continued to decline to the lowest ever level. However, it is critical to continuously monitor the dolphin usage in North Lantau region, in order to determine whether there is any sign of recovery under the post-construction activities of the HKBCF next quarter.

5.1.5                17 weekly environmental site inspections were carried out in the reporting period. Recommendations on mitigation measures for air quality impact, water quality impact and chemical and waste management were given to the Contractor for remediating the deficiencies identified during the site inspections.

5.1.6                Referring to the Contractor’s information, no environmental complaint, notification of summons and successful prosecution was received in the reporting period.

5.2                   Comment and Recommendations

5.2.1                The recommended environmental mitigation measures, as proposed in the EIA reports and EM&A Manuals shall be effectively implemented to minimize the potential environmental impacts from the Project. The EM&A programme would effectively monitor the environmental impacts generated from the construction activities and ensure the proper implementation of mitigation measures.

5.2.2                According to the environmental site inspections performed in the reporting period, the following recommendations were provided:

 

Air Quality Impact

·          Dust suppression measure should be provided.

·          Water spray should be provided at all main exit to prevent sludge from being taken outside the site area.

·          The contractor was reminded to maintain housekeeping to prevent dust leaving from the site.

Construction Noise Impact

·          No specific observation was identified in the reporting period.

Water Quality Impact

·          Stagnant water should be avoided and removed.

·          Silt insider the U-channel should be cleared.

·          The contractor was reminded surface water should be controlled properly to prevent flowing outside.

Chemical and Waste Management

·          All waste generated at the site should be cleaned and collected.

·          The opening of drip tray should be plugged to prevent chemical leakage.

·          Drip tray should be provided for chemical container.

·          The contractor was reminded to maintain housekeeping.

Landscape and Visual Impact

·          No specific observation was identified in the reporting period.

Permit/ Licenses

·          NRMM label should be provided to replace the substandard label.

Others

·          The caps for the water-safety barriers should be provided.
