Remarks: -    Considering the absence of intake pump operation at Windsor House intake (C7), this sensitive receiver was apparently not exist during this period so that no water quality monitoring at C7 for compliance checking was undertaken in this reporting month.

-          The cessation of seawater intake operation for C6 was confirmed on 17 May 2011, the water monitoring at C6 was then terminated since 17 May 2011.

-          It was not included the exceedances recorded at C3 in the daily monitoring from 17 May to 27 May 2011.

 

  1. Investigation found that turbidity and/or SS level exceedances at C3 recorded on 5 and 7 May 2011 were caused by silt screen defect and improper maintenance of deployed silt curtain as identified during regular site inspections. In additional, the exceedances at C3 on 16, 18 and 19 May 2011 were caused by improper control and management of deployed silt curtain as identified during site inspections and monitoring. Other than these exceedances, it was concluded not related to the Project works.

 

Complaints, Notifications of Summons and Successful Prosecutions

  1. There was no environmental complaint recorded in the reporting month.

 

Site Inspections and Audit

  1. The Environmental Team (ET) conducted weekly site inspections for Contract nos. HY/2009/11, HK/2009/01, HK/2009/02, HY/2009/15 and HK/2010/06 under EP no. EP-356/2009 in the reporting month.

Section 10      Conclusion

2.         Project Background

2.1               Background

2.1.1.        ¡§Wan Chai Development phase II and Central-Wan Chai Bypass¡¨ and ¡§Central-Wan Chai Bypass and Island Eastern Corridor Link¡¨ (hereafter called ¡§the Project¡¨) are Designed Project (DP) under the Environmental Impact Assessment Ordinance (Cap. 499) (EIAO).  The Environmental Impact Assessment (EIA) Reports for Central-Wan Chai Bypass and Island Eastern Corridor Link (Register No. AEIAR-041/2001) and Wan Chai Development phase II and Central-Wan Chai Bypass (Register No.: AEIAR-125/2008) have been approved on 31 August 2001 and 11 December 2008 respectively.

2.1.2.        The key purpose of Wan Chai Development Phase II (WDII) is to provide land at Wan Chai North and North Point for construction of the Central-Wan Chai Bypass and Island Eastern Corridor Link (CWB). Land formed under the project will be developed as a world-class waterfront promenade joining that at the new Central waterfront for public enjoyment.

2.1.3.        There is a compelling and present need for the CWB to provide relief to the very congested east-west Connaught Road Central/Harcourt Road / Gloucester Road Corridor (the Corridor) which is currently operating beyond its capacity. The CWB will provide relief to the existing congestion along the Corridor and cater for the anticipated growth of traffic on Hong Kong Island. Without the CWB and its access roads, there will not be sufficient capacity to serve the heavy traffic demands at both strategic and local levels.

 

2.2               Scope of the Project and Site Description

2.2.1.        The Project is located mainly in Wan Chai North, Causeway Bay and North Point, and is demarcated by Gloucester Road and Victoria Park Road to the south, Fenwick Pier Street to the west and Tong Shui Road Interchange to the east, as shown in Figure 2.1.

2.2.2.        The study area encompasses existing developments along the Wan Chai, Causeway Bay and North Point shorelines.

¡P          Land formation for key transport infrastructure and facilities, including the Trunk Road (i.e. CWB) and the associated slip roads for connection to the Trunk Road and for through traffic from Central to Wan Chai and Causeway Bay. The land formed for the above transport infrastructure will provide opportunities for the development of an attractive waterfront promenade for the enjoyment of the public

¡P          Reprovisioning / protection of the existing facilities and structures affected by the land formation works mentioned above

¡P          Extension, modification, reprovisioning or protection of existing storm water drainage outfalls, sewerage outfalls and watermains affected by the revised land use and land formation works mentioned above

¡P          Upgrading of hinterland storm water drainage system and sewerage system, which would be rendered insufficient by the land formation works mentioned above

¡P          Provision of the ground level roads, flyovers, footbridges, necessary transport facilities and the associated utility services

¡P          Construction of the new waterfront promenade, landscape works and the associated utility services

¡P          The Trunk Road (i.e. CWB) within the study area and the associated slip roads for connection to the Trunk Road.

 

2.2.4.        The project also contains various Schedule 2 DPs that, under the EIAO, require Environmental Permits (EPs) to be granted by the DEP before they may be either constructed or operated.

Noise Monitoring Parameters, Frequency and Duration

4.1.3.        The construction noise level shall be measured in terms of the A-weighted equivalent continuous sound pressure level (Leq). Leq (30 minutes) shall be used as the monitoring parameter for the time period between 0700 and 1900 hours on normal weekdays. For all other time periods, Leq (5 minutes) shall be employed for comparison with the Noise Control Ordinance (NCO) criteria. Supplementary information for data auditing, statistical results such as L10 and L90 shall also be obtained for reference.

4.1.4.        Noise monitoring shall be carried out at all the designated monitoring stations. The monitoring frequency shall depend on the scale of the construction activities. The following is an initial guide on the regular monitoring frequency for each station on a weekly basis when noise generating activities are underway:

¡P          one set of measurements between 0700 and 1900 hours on normal weekdays.

4.1.5.        If construction works are extended to include works during the hours of 1900 ¡V 0700 as well as public holidays and Sundays, additional weekly impact monitoring shall be carried out during respective restricted hours periods. Applicable permits under NCO shall be obtained by the Contractor.

Monitoring Equipment

4.1.6.        As referred to in the Technical Memorandum ™ issued under the NCO, sound level meters in compliance with the International Electrotechnical Commission Publications 651: 1979 (Type 1) and 804: 1985 (Type 1) specifications shall be used for carrying out the noise monitoring. Immediately prior to and following each noise measurement the accuracy of the sound level meter shall be checked using an acoustic calibrator generating a known sound pressure level at a known frequency. Measurements may be accepted as valid only if the calibration level from before and after the noise measurement agree to within 1.0 dB.

4.1.7.        Noise measurements shall not be made in fog, rain, wind with a steady speed exceeding 5 m/s or wind with gusts exceeding 10 m/s. The wind speed shall be checked with a portable wind speed meter capable of measuring the wind speed in m/s.

 

4.2               Air Monitoring

Air Monitoring Parameters, Frequency and Duration

4.2.2.        One-hour and 24-hour TSP levels should be measured to indicate the impacts of construction dust on air quality. The 24-hour TSP levels shall be measured by following the standard high volume sampling method as set out in the Title 40 of the Code of Federal Regulations, Chapter 1 (Part 50), Appendix B.

4.2.3.        All relevant data including temperature, pressure, weather conditions, elapsed-time meter reading for the start and stop of the sampler, identification and weight of the filter paper, and any other local atmospheric factors affecting or affected by site conditions, etc., shall be recorded down in detail.

4.2.4.        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

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

¡P          0.6 - 1.7 m3 per minute adjustable flow range;

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

¡P          installed with elapsed-time meter with +/- 2 minutes accuracy for 24 hours operation;

¡P          capable of providing a minimum exposed area of 406 cm2;

¡P          flow control accuracy: +/- 2.5% deviation over 24-hour sampling period;

¡P          equipped with a shelter to protect the filter and sampler;

¡P          incorporated with an electronic mass flow rate controller or other equivalent devices;

¡P          equipped with a flow recorder for continuous monitoring;

¡P          provided with a peaked roof inlet;

¡P          incorporated with a manometer;

¡P          able to hold and seal the filter paper to the sampler housing at horizontal position;

¡P          easily changeable filter; and

¡P          capable of operating continuously for a 24-hour period.

 

4.2.6.        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

4.2.7.        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.

4.2.8.        An alternative non-HOKLAS accredited laboratory was set-up for carrying out the laboratory analysis, the laboratory equipment was approved by the ER on 8 February 2011 and the measurement procedures were witnessed by the IEC.  Any measurement performed by the laboratory was be demonstrated to the satisfaction of the ER and IEC.  IEC shall regularly audit to the measurement performed by the laboratory to ensure the accuracy of measurement results. 

4.2.9.        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.

4.2.10.    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.

4.2.11.    All the collected samples shall be kept in a good condition for 6 months before disposal.

 

4.3               Water Quality Monitoring

4.3.1.        The EIA Report has identified that the key water quality impact would be associated with the dredging works during the construction phase.  Marine water quality monitoring for dissolved oxygen (DO), suspended solid (SS) and turbidity is therefore recommended to be carried out at selected WSD flushing water intakes.  The impact monitoring should be carried out during the proposed dredging works to ensure the compliance with the water quality standards.

4.3.2.        The updated EM&A Manual for EP-356/2009 (Version in March 2011) is approval by EPD on 29 April 2011. As such, the Action Level and Limit Level for the wet season (April ¡V October) will be effected and applied to the water quality monitoring data from 30 April 2011.

Water Quality Monitoring Stations

4.3.3.        It is proposed to monitor the water quality at 9 WSD salt water intakes and 12 cooling water intakes along the seafront of the Victoria Harbour. The proposed water quality monitoring stations of the Project are shown in Table 4.4 and Figure 4.1.  Appendix 4.1 shows the established Action/Limit Levels for the monitoring works.

6.3.1.        No exceedance was recorded in the reporting month.

 

6.4               Water Quality Monitoring

 

Contract no. HY/2009/11 ¡V Central ¡V Wanchai Bypass, North Point Reclamation

6.4.1.        Referring to the exceedances shown in Table 5.9, the occasionally Action and Limit level exceedances of turbidity and suspended solid were recorded at Stations C8 and C9. Since there were numerous unknown outfalls from the nearby coastal area closed to the cooling intakes C8 and C9, it causes the potential for accumulation of pollutants near the intakes and may lead to potential water quality deterioration at the seawater intake points. Besides, muddy discharge from the outfalls near Oil Street and C9 were recorded in reporting month.

6.4.2.        Major marine works were only installations of caisson seawall at NPR2E and reclamation work at NPR1 and NPR2W in this reporting month. Proper condition of silt curtain was provided between the barge and the seawall during the filling material transportation. The recorded turbidity and SS exceedances were concluded as not project-related.

6.4.3.        Reviewed the trend of overall results at all monitoring stations nearer the marine work area, the turbidity exceedance recorded at WSD15 on 12 May 2011 while low turbidity and SS levels were recorded at the stations near the marine work area without exceeded the action and limit level. Besides, the exceedances recorded at WSD17 during mid-flood were located in the upstream of the marine works. Thus, theses turbidity and SS exceedances were considered not related to the Project works.

Contract no. HK/2009/01 - Wan Chai Development Phase II ¡V Central ¡VWanchai Bypass at HKCEC

6.4.4.        Since there were only filling works at HKCEC1 and no dredging works of the Cross Harbour Water Mains on 5 May 2011, no potential water impact was near the station C1. Thus, it was considered not related to the Project works.

6.4.5.        Referring to exceedances recorded at WSD19 on 5 May 2011 during mid-ebb, it was located in upstream of the Project works, the exceedances were definitely non-works related under the Project.

6.4.6.        Exceedances of turbidity and/or SS level at C3 were recorded on 28 and 30 April, 3, 5, 7, 12, 14, 16, 18, 19, 23, 25 and 27 May 2011. Investigation found that the turbidity levels outside the silt screen on 28, 30 April and 3, 12 and 14 May 2011 were well below the Action Level while turbidity exceedances were recorded inside the silt screen. Recorded exceedances on these days might be caused by trapping of material inside the silt screen and not adequately removed by Contractor in time.

6.4.7.        In the additional turbidity measurements at the outside the silt screen on 5, 7, 16, 18, and 19 May 2011, it indicated that the turbidity levels outside the silt screen were also higher than the Limit Level. In the further investigation, silt screen defect and deployed silt curtain not properly maintained as identified during regular site inspections were the findings to cause the exceedances recorded on 5 and 7 May 2011. Besides, deployed silt curtain was not properly managed and controlled as identified during site inspections and monitoring on 16, 18 and 19 May 2011. These exceedances were concluded to be in relation to the deployed silt screen and silt curtain. The frequency of water quality monitoring has been increased to daily from 17 May 2011 so as to keep in view of any further deterioration of water quality in water channel. Filling operation was then suspended since 19 May 2011 morning.

6.4.8.        The turbidity inside the silt screen on 23, 25 and 27 May 2011 were higher than the turbidity outside the silt screen. The exceedances recorded on these days were considered in relation to the accumulation of wastewater and debris since a discharge pipe was discovered inside the silt screen by Contractor on 24 May 2011. The monitoring frequency was then resumed to normal monitoring frequency on 27 May 2011. The diversion of the discharge pipe is under liaison with the stakeholder. Follow-up action will be taken in the coming month.

6.4.9.        More detail of the action taken and the recommendation for the exceedances can be referred to Appendix 6.2.

Contract no. HK/2009/02 - Wan Chai Development Phase II ¡V Central ¡V Wan Chai Bypass at WanChai East

6.4.10.    There was one SS level at WSD21 exceeded the Action level on 3 May 2011 during mid-ebb. Washing screen by WSD was observed during the water monitoring. The silt screen was checked in proper condition during water quality monitoring. Besides, the silt curtain for the dredging work at submarine outfall was then checked in proper condition during the site inspection on 5 May 2011. It was concluded that the SS level exceedance was not related to the Project works.

Contract no. HY/2009/15 - Central-Wanchai Bypass ¡V Tunnel (Causeway Bay Typhoon Shelter Section)

6.4.11.    There was one DO level at ex- WPCWA SE exceeded the Action Level on 25 May 2011 in the Enhanced DO monitoring. According to the information reported by Contractor HY/2009/15, no marine activities were carried out at ex-WPCWA on 25 May 2011. In view that no marine activities were undertaken and no odour nuisance was noted during monitoring, the DO exceedance was considered not related to the Project.

6.4.12.    No exceedance was recorded in the reporting month.

6.4.13.    Summary for notification of exceedances can be referred to Appendix 6.2.

 

6.5               Review of the Reasons for and the Implications of Non-compliance

6.5.1.        There was no non-compliance from the site audits in the reporting period. The observations and recommendations made in each individual site audit session were presented in Section 8.

6.5.2.        There were exceedances of turbidity and/or SS level recorded at C3 on 5, 7, 16, 18 and 19 May 2011 that were considered in relation to the deployed silt screen and silt curtain as identified during the site inspection and monitoring.

 

6.6               Summary of action taken in the event of and follow-up on non-compliance

6.6.1.        When the exceedance was recorded during water quality monitoring, repeated in-situ measurement and additional turbidity measurement were immediately taken outside the silt screen when the Action Level or Limit Level exceedance was recorded inside the silt screen for checking of relation from the filling works. Diver inspection on the silt screen and silt curtain was conducted on 5 May 2011. The maintenance works of geotextile was then conducted on 6 and 7 May 2011. Additional silt curtains have been installed in HKCEC water channel on 7 May 2011.

6.6.2.        In response to further recorded exceedances at water monitoring station C3, the frequency of water quality monitoring has been increased to daily from 17 May 2011 so as to keep in view of any further deterioration of water quality in water channel. Filling operation was then suspended from 19 May 2011 morning until 23 May 2011 morning.

6.6.3.        A discharge pipe for HKCEC was discovered located in between the C3 intake inlets and inside the silt screen by Contractor on 24 May 2011. A site investigation with ARE and SIOW from AACL, ET, IEC, Contractor and stakeholder was conducted on 27 May 2011 to confirm the location of the discharge pipe. The monitoring frequency was then resumed to normal monitoring frequency on 27 May 2011. The diversion of the discharge pipe is under liaison with stakeholder. Follow-up action will be taken in the coming month.

6.6.4.        The implementation of the recommended mitigation measures would be continuously followed-up and reported in the next reporting period.

7.         Cumulative Construction Impact due to the Concurrent Projects

7.0.1.        According to Condition 3.4 of the EP-356/2009, this section addresses the relevant cumulative construction impact due to the concurrent activities of the current projects including the Central Reclamation Phase III, Central-Wanchai Bypass and Island Eastern Corridor Link projects.

7.0.2.        From the Monthly EM&A report (April 2011) of Central Reclamation Phase III (CRIII) the key works in May 2011 are as follows:

¡P          Type A filling in FRAW and FRAE above +2.5mPD;

¡P          General filling works above +2.5mPD in IRAE;

¡P          Surcharging in FRAW and FRAE;

¡P          Construction of cantilever slab at caisson ;

¡P          Construction of storm and foul drainage and gullies in hinterlands for Road P2, Road D7, and Road D9;

¡P          Construction of GPO boundary wall;

¡P          Construction of PLA boundary wall and entrance;

¡P          Construction of Promenade enhancement works;

¡P          Construction of buildings at PLA berth;

¡P          Road P2 Underpass ramp structures;

¡P          Precasting for retaining wall (offsite);

¡P          Installation of cooling mains discharge pipes in FRAE and FRAW;

¡P          Bulk excavation to formation level at CWB works;

¡P          Construction of CWB structure;

¡P          Disposal of material off-site to Government fill banks; and

¡P          Strengthening of Man Yiu Street Footbridge

 

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 activities under Wan Chai Development Phase II were the filling works at North Point Reclamation Shoreline Subzone (NPR2E) and (NPR1& NPR2W), the filling at WCR1 and dredging at Wan Chai Reclamation Shoreline Subzone (Submarine sewage pipeline) respectively, filling at HKCEC1 and dredging at TCBR and filling at TPCEAE, and the dredging works at MTR Tunnel Crossing in the reporting month. The major environmental impact was water quality impact at North Point and Wan Chai.

7.0.4.        The major environmental impacts generated from the filling work at Central Reclamation Phase III were only located along the coastline of Central and Admiralty while the adverse water impact was located in the HKCEC water channel in relation to the filling operation causing exceedances at station C3 in this reporting month. Other than the exceedances recorded at C3, it was concluded not related to the Project works. Thus, it was unlikely to have cumulative impact from CRIII. It is evaluated the cumulative construction impact from the concurrent projects including Wan Chai Development Phase II and Central Reclamation Phase III was insignificant.
