SUMMARY OF EXCEEDANCES, COMPLAINTS,
NOTIFICATION OF SUMMONS AND SUCCESSFUL PROSECUTION
4.1
Summary of
Exceedance of the Environmental Quality Performance Limit
4.1.1
Summary of Action and Limit Level exceedance of 1-hr
TSP level and 24-hr TSP level at AMS6 is reported in the monthly EM&A
Reports (for June, July and August 2017) prepared by Contract No. HY/2011/03.
4.1.2
There was no Action and Limit Level exceedance of
1-hr TSP level and 24-hr TSP level recorded at station AMS7 by the
Environmental Team of Contract No. HY/2010/02 during the reporting period.
4.1.3
There
was no Action and Limit Level exceedance for noise recorded at station NMS2 and
station NMS3B by the Environmental Team of Contract No. HY/2010/02 during the
reporting period.
4.1.4
There
were two Action and Limit Level exceedances of suspended solids recorded at station SR3 during mid-ebb
tide on 12 July 2017 and station IS7 during mid-flood tide on 14 July 2017. The
investigation reports (including the causes of exceedance, action taken and
recommendation for mitigation) for Action or Limit Level Non-compliance were
provided in Appendix I.
Regarding
the exceedance on 12 July 2017, marine-based construction works were undertaken
in Box Culvert B and there was one derrick lighter delivered sand to the work
site of Three Runway Project on 12 July 2017 under Contract No. HY/2013/03.
Both marine-based construction works and the route of marine transportation
were far away from the concerned WQM station SR3. There was no notification of
exceedance received at the WQM stations closer to the marine-based construction
works areas, such as IS(Mf)11, IS10, IS17 and SR7. Besides, the SS exceedance
was recorded at 13:49. The derrick lighter was deposited at HKBCF from morning
until 16:00. Therefore, it was unlikely to generate any suspended solids to
cause the SS exceedance recorded at the concerned WQM station SR3 during
mid-ebb tide on 12 July 2017. Besides,
the water quality mitigation measures as mentioned in EM&A Manual and EP were
fully implemented in Contract No. HY/2013/03. Hence, the exceedance on 12 July
2017 was not related to Contract No. HY/2013/03.
Regarding the exceedance on 14 July
2017, marine-based construction works were undertaken in Box Culvert B and
there were two derrick lighters delivered sand to the work site of Three Runway
Project on 14 July 2017 under Contract No. HY/2013/03. Both marine-based
construction works and the routes of marine transportation were undertaken in
the north side of HKBCF while the concerned WQM station IS7 was in the
south-west side. As the concerned monitoring station was far away from both
marine-based construction works and the routes of marine transportation and
there was no notification of exceedance received at the WQM stations closer to
the works areas, such as IS(Mf)11, IS10, IS17 and SR7,
it was unlikely to generate any suspended solids to cause the SS exceedance
recorded at the concerned WQM station IS7 during mid-flood tide on 14 July
2017. Besides, the water quality mitigation measures as mentioned in EM&A
Manual and EP were fully implemented in Contract No. HY/2013/03. Hence, the
exceedance on 14 July 2017 was not related to Contract No. HY/2013/03.
After
investigation, it was concluded that the exceedances were not related to Contract
No. HY/2013/03 due to the above reasons. There was no Action and Limit Level
exceedance recorded on other monitoring dates at the monitoring stations shown
as shown at Table 4.1 by the
Environmental Team of Contract No. HY/2010/02 during the reporting period.
Although
the exceedances were not relevant to Contract No. HY/2013/03, the Contractor
was reminded to continue to fully maintain all water quality mitigation
measures and ensure the silt curtain is fully maintained to prevent any water
quality impact to seawater.
4.1.5
Ecological monitoring results at all transects are
reported in the EM&A report (for the reporting period) prepared by Contract
No. HY/2010/02.
