3.2.4.     For regular impact monitoring, the sampling frequency of at least once in every six-days, shall be strictly observed at all the monitoring stations for 24-hour TSP monitoring. For 1-hour TSP monitoring, the sampling frequency of at least three times in every six-days should be undertaken when the highest dust impact occurs.

Sampling Procedure and Monitoring Equipment

3.2.5.     High volume samplers (HVSs) in compliance with the following specifications shall be used for carrying out the 1-hour and 24-hour TSP monitoring:

          0.6 1.7 m3 per minute adjustable flow range;

          Equipped with a timing / control device with +/- 5 minutes accuracy for 24 hours operation;

          Installed with elapsed-time meter with +/- 2 minutes accuracy for 24 hours operation;

          Capable of providing a minimum exposed area of 406 cm2;

          Flow control accuracy: +/- 2.5% deviation over 24-hour sampling period;

          Equipped with a shelter to protect the filter and sampler;

          Incorporated with an electronic mass flow rate controller or other equivalent devices;

          Equipped with a flow recorder for continuous monitoring;

          Provided with a peaked roof inlet;

          Incorporated with a manometer;

          Able to hold and seal the filter paper to the sampler housing at horizontal position;

          Easily changeable filter; and

          Capable of operating continuously for a 24-hour period.

3.2.6.     Initial calibration of dust monitoring equipment shall be conducted upon installation and thereafter at bi-monthly intervals. The transfer standard shall be traceable to the internationally recognized primary standard and be calibrated annually. The concern parties such as IEC shall properly document the calibration data for future reference. All the data should be converted into standard temperature and pressure condition.

Laboratory Measurement / Analysis

3.2.7.     A clean laboratory with constant temperature and humidity control, and equipped with necessary measuring and conditioning instruments to handle the dust samples collected, shall be available for sample analysis, and equipment calibration and maintenance. The laboratory should be HOKLAS accredited.

3.2.8.     Filter paper of size 8 x 10 shall be labelled before sampling. It shall be a clean filter paper with no pinholes, and shall be conditioned in a humidity-controlled chamber for over 24-hours and be pre-weighed before use for the sampling.

3.2.9.     After sampling, the filter paper loaded with dust shall be kept in a clean and tightly sealed plastic bag. The filter paper shall then be returned to the laboratory for reconditioning in the humidity controlled chamber followed by accurate weighing by an electronic balance with readout down to 0.1 mg. The balance shall be regularly calibrated against a traceable standard.

7. Cumulative Construction Impact due to the Concurrent Projects

7.0.1.     This section addresses the relevant cumulative construction impact due to the concurrent activities of the current projects including the Central Reclamation Phase III (CRIII), Wan Chai Development Phase II (WDII), Central-WanChai Bypass (CWB), Island Eastern Corridor Link projects (IECL) and Wan Chai Development Phase II Central Wan Chai Bypass at Wan Chai East (CWB Tunnel).

7.0.2.     According to the Monthly EM&A report (July, August and September 2013) of Central Reclamation Phase III (CRIII) for Contract HK 12/02, surface drainage and footpath construction adjacent to GPO, modification to the junction of Road D8 and Road P2, modification of timber decks at advance promenade, paving and landscaping work behind GPO boundary wall, and additional run-in at Road P2 footpath (north bound) outside ESB S8.1 were performed in the reporting period. The water quality monitoring was completed in October 2011 and no Project-related exceedance was recorded for air and noise monitoring. It can be concluded that cumulative construction impact due to the concurrent activities of the current projects with the Central Reclamation Phase III (CRIII) undertaken by contractor HK12/02 was insignificant.

7.0.3.     According to the construction programme of Wan Chai Development Phase II, Central-Wan Chai Bypass and Island Eastern Corridor Link projects, the major construction activity under Wan Chai Development Phase II were marine works at HKCEC areas, cross-harbour Watermains, Fresh Watermains and Cooling Watermains Installations, tunnel works at Wan Chai East, ELS work and pipe roofing works at TS4 and cut and cover tunnel construction at TPCWAE, excavation and tunnel works at Central Interchange, ELS and box culvert construction at North Point area, bridge construction and tunnel works at Central Interchange, ELS segment launching works and IEC parapet demolition at North Point area. The major environmental impact was water quality impact at Causeway Bay and Wan Chai. Land-based construction activities were diaphragm wall construction at TS2, ELS works and excavation at TS2, ELS work and pipe roofing works at TS4, cut and cover tunnel construction at TPCWAE, tunnel works at Central and ELS work at North Point and tunnel works at Wan Chai East in the reporting period.

7.0.4.     The major environmental impacts generated from tunnel works at Central and tunnel works at Wan Chai East, IECL and Causeway Bay Typhoon Shelter were undertaken in the reporting period. No significant air impact from construction activities was anticipated in the reporting period. Besides, no project-related exceedances were recorded during the air and noise environmental monitoring events in the reporting period. Thus, it is evaluated that the cumulative construction impact from the concurrent projects including Wan Chai Development Phase II was insignificant.

8. Conclusion

8.0.1.     The EM&A programme was carried out in accordance with the EM&A Manual requirements, minor alterations to the programme proposed were made in response to changing circumstances.

8.0.2.     No non-compliances were noted and no prosecutions were received during the reporting period.

8.0.3.     The construction programmes of individual contracts are provided in Appendix 8.1.
