Portion)¡¨ (hereafter referred to as ¡§the Contract¡¨) for the Highways Department
of Hong Kong Special Administrative Region (HKSAR). The Contract was awarded to
China Harbour Engineering Co., Ltd. (hereafter referred to as ¡§the Contractor¡¨)
and ETS-Testconsult Limited was appointed as the Environmental Team (ET) by the
Contractor.
The Contract is part of Hong Kong¡VZhuhai¡VMacao
Bridge HKBCF which is a ¡§Designated Project¡¨, under Schedule 2 of the
Environmental Impact Assessment Ordinance (EIAO) (Cap 499) and Environmental
Impact Assessment (EIA) Report (Register No. AEIAR-145/2009) was prepared for
the Project. The current Environmental Permit (EP) No.
EP-353/2009/K for HKBCF was issued on 11 April 2016. These documents are
available through the EIA Ordinance Register. Site preparation works of the
Contract was started on 25 July 2014 and the construction works of the Contract
commenced on 24 November 2014.
ETS-Testconsult Limited has been appointed by
the Contractor to implement the Environmental Monitoring & Audit (EM&A)
programme for the Contract in accordance with the Updated EM&A Manual for
HKBCF (Version 1.0) and provide environmental team services to the Contract.
This is the Twenty-seventh Monthly Environmental
Monitoring and Audit (EM&A) Report for the Contract which summaries
findings of the EM&A works conducted during the reporting
period from 01 February to 28 February 2017.

As
informed by the Contractor, site
activities were carried out in
this reporting month:
¡± Bored piles works in Portion C;
¡± Pier / Abutment in Portion C & F;
¡± Pile Cap in Portion C & F;
¡± Pre-bored H-pile for sign gantries in Portion C & F;
¡± Storm drain and water main construction;
¡± Retaining wall, slop and earth works;
¡± Footing construction of directional signs, cable trench and
ducting;
¡± Marine Delivery of
precast segment & Construction of bridge deck in Portion D, A, E, C & F
¡± Marine sediment

Environmental Monitoring and Audit Progress
The monthly EM&A programme was
undertaken in accordance with the Updated EM&A Manual for HKBCF (Version
1.0). It should be noted that the air quality and noise monitoring works for
the Contract are covered by Contract No. HY/2010/02 ¡§Hong Kong-Zhuhai-
Environmental Site Inspection:
02, 09, 16
& 23 February 2017
Breaches of
Action and Limit Levels
Summary of
Action and Limit Level exceedance of 1-hr TSP level and 24-hr TSP level at AMS6
shall be referred to the monthly EM&A report prepared by Contract No.
HY/2011/03.
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.
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.
There
were two Action Level exceedances of SS on impact water quality
monitoring at station IS8 and SR7 during
mid-flood tide recorded
on 06 February 2017 and 15
February 2017,
one Action Level exceedance of SS on impact water quality
monitoring at station SR6 during mid-ebb tide recorded on 10 February 2017.
After
investigation, there was concluded that the three
exceedances were not relevant to this Contract
since there was no marine works or barge of this Contract worked at HKBCF
reclamation site near the sea area or area near the monitoring station IS8 and SR7 from 04
February 2017 to 06 February 2017 and 13
February 2017 to 15
February 2017 which was
unlikely to generate suspended solids in the marine water. Besides, during 08 February 2017 to 10 February
2017, there was no marine works worked at HKBCF
reclamation site near the sea area or area near the monitoring station SR6 except only one marine pre-cast segment
delivery barge which passed through the north-east side with
distance more than 4000 meters from the monitoring station SR6. Therefore, it is
unlikely that the SS exceedances recorded at IS8 and SR7 during
mid-flood tide on 06 February 2017 and 15 February 2017 and SR6 during mid-flood
tide on 10 February 2017 were contributed by
the works under Contract No. HY/2013/02. The Investigation Reports No. 011, 012 and 013 (including the causes of exceedance,
action taken and recommendation for mitigation) for Action or Limit Level
Non-compliance were provided in Appendix
J. There
was no Action
and Limit Level
exceedance recorded on other monitoring date at the monitoring
stations showed at Table 4.1 by the Environmental Team of Contract No.
HY/2010/02 during the reporting period.
Impact
dolphin monitoring results at all transects are reported in the EM&A Report
prepared for Contract No. HY/2010/02.

Notes: 1. "depth-averaged" is
calculated by taking the arithmetic means of reading of all three depths. |
|||
2. For DO, non-compliance of the water quality
limits occurs when monitoring result is lower than the limits. |
|||
3. For turbidity, SS, non-compliance of the water quality limits occurs
when monitoring result is higher than the limits. |

4.3
Monitoring Result
4.3.1
The monitoring results for the monitoring
stations showed in Table 4.1 are reported in the monthly EM&A Report
prepared for Contract No. HY/2010/02. There
was two Action Level
exceedance of SS at station IS8
and SR7 during mid-flood tide recorded
on 06 February 2017 and 15 February 2017, one
Action Level exceedances of SS at station SR6 during mid-ebb tide recorded on 10 February 2017.
4.3.2
The three exceedances were not relevant to this Contract since there was no marine
works or barge of this Contract worked at HKBCF
reclamation site near the sea area or area near the monitoring station IS8 and SR7 from 04 February 2017 to 06 February 2017 and 13 February 2017 to 15
February 2017 which was unlikely to generate suspended solids in
the marine water.
Besides, during 08 February 2017 to 10 February 2017, there was no
marine works worked
at HKBCF reclamation site near the sea area or area near the monitoring station
SR6 except only one
marine pre-cast segment delivery barge which
passed through the
north-east side with distance more than 4000 meters from the monitoring station
SR6. Therefore,
it is unlikely that the SS exceedances recorded at IS8
and SR7 during mid-flood tide on 06 February 2017 and 15
February 2017 and SR6 during mid-flood tide on 10 February 2017 were contributed by the works under Contract No.
HY/2013/02. The water quality
mitigation measures as mentioned in EM&A Manual and EP was fully
implemented in this Contract which including maintenance of the silt curtain on
a daily basis by Contract No. HY/2010/02 etc. Hence, the exceedances were considered as
non-Project related.
4.3.3
After
investigation, there was concluded that the exceedances were not relevant to
this Contract due to the above mentioned reasons. The Investigation Reports No.
011, 012 and 013 (including the causes of exceedance, action taken and
recommendation for mitigation) for Action or Limit Level Non-compliance were
provided in Appendix J. There was no
Action and Limit Level exceedance recorded on other date at the monitoring
stations showed in Table 4.1 by the
Environmental Team of Contract No. HY/2010/02 during the reporting period.
4.3.4
Although the exceedance was not relevant to this
Contract, the Contractor was reminded to ensure that the maintenance of
perimeter silt curtains with respect to the work boundary of this Contract
carried out by the Contractor of Contract
No. HY/2010/02 is maintained properly.

Environmental Site Inspection Schedule for the Coming Month
8.1 Conclusions
8.1.4
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.
8.1.5
There were
two Action Level exceedances of SS on impact water quality monitoring at station IS8 and SR7 during mid-flood tide recorded
on 06 February 2017 and 15 February 2017, one Action Level
exceedance of SS on impact water
quality monitoring at station SR6 during mid-ebb tide recorded on 10 February 2017. After investigation, there was concluded that the three exceedances were not relevant to this Contract since there was no marine
works or barge of this Contract worked at HKBCF
reclamation site near the sea area or area near the monitoring station IS8 and SR7 from 04 February 2017 to 06 February 2017 and 13 February 2017 to 15
February 2017 which was unlikely to generate suspended solids in
the marine water.
Besides, during 08 February 2017 to 10 February 2017, there was no
marine works worked
at HKBCF reclamation site near the sea area or area near the monitoring station
SR6 except only one
marine pre-cast segment delivery barge passed through the north-east side with
distance more than 4000 meters from the monitoring station SR6. Therefore, it is unlikely
that the SS exceedances recorded at IS8
and SR7 during mid-flood tide on 06 February 2017 and 15
February 2017 and SR6 during mid-flood tide on 10 February 2017 were contributed by the works under Contract No.
HY/2013/02. The Investigation Reports
No. 011, 012 and 013 (including the causes of
exceedance, action taken and recommendation for mitigation) for Action or Limit
Level Non-compliance were provided in Appendix
J. Although the exceedance
was not relevant to this Contract, the Contractor was reminded to ensure that maintenance of
perimeter silt curtains with respect to the work boundary of this Contract
carried out by the Contractor of Contract No. HY/2010/02 is maintained properly.
8.1.6
Impact
dolphin monitoring results at all transects are reported in the EM&A Reports prepared for Contract
No. HY/2010/02.
8.1.7
There were no complaints
received during the reporting period.
8.1.8
There were no notifications of summons or
prosecutions received during the
reporting period.
