under Contract No. HY/2010/02, which include ground investigation (GI) works,
construction of temporary timber platform, removal of jetty and reinstatement
of seawall at the western section and construction of outfall at the eastern
seawall, would cause limited disturbance to water column and not to the seabed.
In view of this, a proposal for change of EM&A programme/requirements was
prepared by ET in accordance with Condition 5.1 of EP-353/2009/K and Condition
4.1 of EP-354/2009/D, to terminate water quality monitoring works at stations
IS5, IS(Mf)6, IS8, SR4(N), SR5(N), SR6, SR10A, SR10B(N), CS4, CSA and CS6, and
dolphin monitoring (line-transect vessel survey method) covering NEL and NWL
when perimeter silt curtain under the Contract is completely removed and vessel
traffic numbers average 10 per month for Contract No. HY/2010/02. A revised
proposal has been updated and sent to IEC/ENPO for their further review on 15
August 2017 and IEC/ENPO verified the revised proposal on 16 August 2017. The
revised proposal has been sent to authority by project team for review and

Summary
of EM&A Programme Requirements
2.1
Monitoring Parameters
2.1.1
The Contract Specific EM&A Manual designated 4 air quality
monitoring stations, 2 noise monitoring stations, 21 water monitoring stations
(9 Impact Stations, 7 Sensitive Receiver Stations and 5 Control/Far Field
Stations) to monitor environmental impacts on air quality, noise and water
quality respectively. Pre-set and fixed transect line vessel based dolphin
survey was required in two AFCD designated areas (Northeast and Northwest
Lantau survey areas). The impact dolphin monitoring at each survey area should
be conducted twice per month.
2.1.2
For impact air quality monitoring, monitoring locations AMS2 (Tung Chung
Development Pier) and AMS7 (Hong Kong SkyCity Marriott Hotel) were set up at
the proposed locations in accordance with Contract Specific EM&A Manual.
The conditional omission of Monitoring Station AMS6 was effective since 19
November 2012. For monitoring location AMS3 (Ho Yu College), as proposed in the
Contract Specific EM&A Manual, approval for carrying out impact monitoring
could not be obtained from the principal of the school. Permission on setting
up and carrying out impact monitoring works at nearby sensitive receivers, like
Caribbean Coast and Coastal Skyline, was also sought. However, approvals
for carrying out impact monitoring works within their premises were not
obtained. Impact air quality monitoring was conducted at site boundary of the
site office area in Works Area WA2 (AMS3B) respectively. Same baseline and
Action Level for air quality, as derived from the baseline monitoring data
recorded at Ho Yu College, was adopted for this alternative air quality
location.
2.1.3
For impact noise monitoring, monitoring locations NMS2 (Seaview Crescent
Tower 1) was set up at the proposed locations in accordance with Contract
Specific EM&A Manual. However, for monitoring location NMS3 (Ho Yu
College), as proposed in the Contract Specific EM&A Manual, approval for
carrying out impact monitoring could not be obtained from the principal of the
school. Permission on setting up and carrying out impact monitoring works at
nearby sensitive receivers, like Caribbean Coast and Coastal Skyline, was also
sought. However, approvals for carrying out impact monitoring works
within their premises were not obtained. Impact noise monitoring was conducted
at site boundary of the site office area in Works Area WA2 (NMS3B)
respectively. Same baseline noise level, as derived from the baseline
monitoring data recorded at Ho Yu College was adopted for this alternative
noise monitoring location. Reference is made to ET¡¦s proposal of relocation of
air quality monitoring station (AMS7) dated on 2 February 2015, with
no further comment received from IEC on 2 February 2015 and no objection
received from EPD on 5 February 2015, the impact air quality monitoring station
AMS7 (Hong Kong SkyCity Marriott Hotel) has been relocated to AMS7A (Chu Kong
Air-Sea Union Transportation Company Limited) on 3 February 2015. Action Level
for air quality, as derived from the baseline monitoring data recorded at Hong
Kong SkyCity Marriott Hotel, was adopted for this alternative air quality
location.
2.1.4
As informed by the premises owner of (AMS7A) - Chu Kong Air-Sea Union
Transportation Co. LTD would not grant us the permission to install air quality
monitoring equipment (High volume sampler) and conduct 1-hour TSP/24 hour TSP
monitoring at the premises of Chu Kong Air-Sea Union Transportation Co. LTD
after December 2015. In order to fulfil the EM&A requirement of this
Contract, as permission to conduct impact air quality monitoring at the premise
of Hong Kong SkyCity Marriott Hotel has been granted in December 2015, ET
proposed relocation of air quality monitoring station (AMS7A) on 15 December
2015, with no further comment received from IEC on 15 December 2015 and no
particular comment received from EPD on 21 December 2015, the impact air
quality monitoring station AMS7A (Chu Kong Air-Sea Union Transportation Company
Limited) has been relocated to AMS7 (Hong Kong SkyCity Marriott Hotel) on 30
December 2015. The impact air quality monitoring for December 2015 was
conducted before the relocation of AQM Station from AMS7A to AMS7. The impact
air quality monitoring has been conducted at AMS7 (Hong Kong SkyCity Marriott
Hotel) since 1 January 2016, Action Level for air quality, as derived from the
baseline monitoring data recorded at Hong Kong SkyCity Marriott Hotel will be
adopted for this air quality monitoring location.
2.1.5
In accordance with the Contract Specific EM&A Manual, twenty-one
stations were designated for impact water quality monitoring. The nine Impact
Stations (IS) were chosen on the basis of their proximity to the reclamation
and thus the greatest potential for water quality impacts, the seven Sensitive
Receiver Stations (SR) were chosen as they are close to the key sensitive
receives and the five Control/ Far Field Stations (CS) were chosen to
facilitate comparison of the water quality of the IS stations with less
influence by the Project/ ambient water quality conditions.
2.1.6
Due to safety concern and topographical condition of the original
locations of SR4 and SR10B, alternative impact water quality monitoring
stations, naming as SR4(N) and SR10B(N), were adopted, which are situated in
vicinity of the original impact water quality monitoring stations (SR4 and
SR10B) and could be reachable. Same baseline and Action Level for water
quality, as derived from the baseline monitoring data recorded, were adopted
for these alternative impact water quality monitoring stations.
2.1.7
The monitoring locations used during the reporting quarter are depicted
in Figures 2, 3 and 4 respectively.
2.1.8
Due to the commencement of marine work of the Expansion of Hong Kong
International Airport into a Three-Runway System
(3RS Project), a large portion of
works site boundary will be established at the northern
part of the existing airport Island. The recent arrangement of works boundary
of 3RS Project which delineates the boundary of the designated 3RS Project (for
the indicative 3RS boundary, please refer to Figure 5). The works area of
3RS project will affect several water quality monitoring stations and the
dolphin monitoring transect lines which are
being used for conducting monitoring under
Contract No. HY/2010/02. The EM&A Programme for the HZMB HKBCF
Project will therefore be affected. As a result, a proposal was prepared by ET
in September 2016 in accordance with condition 5.1 of EP-353/2009/K and
condition 4.1 of EP-354/2009/D, to relocate water quality monitoring stations
from SR5, IS10, CS(Mf)3 and alternate the transect lines of impact
dolphin monitoring 2, 3, 4, 5, 6 and 7. A revised proposal has been
updated and sent to IEC/ENPO for their further review on 24 March 2017 and
IEC/ENPO verified the revised proposal on the same date. The revised proposal
has been sent to authority by project team for review and approval on 3 April
2017. The authority subsequently approved the proposal on 12 May 2017.
2.1.9
Due to substantial completion of marine works by the end of June 2017,
it is anticipated that the remaining construction works under Contract No.
HY/2010/02, which include ground investigation (GI) works, construction of
temporary timber platform, removal of jetty and reinstatement of seawall at the
western section, construction of outfall at the eastern seawall, would cause
limited disturbance to water column and not to the seabed. In view of this, a
proposal for change of EM&A programme/requirements was prepared by ET in
accordance with Condition 5.1 of EP-353/2009/K and Condition 4.1 of
EP-354/2009/D, to terminate water quality monitoring works at stations IS5,
IS(Mf)6, IS8, SR4(N), SR5(N), SR6, SR10A, SR10B(N), CS4, CSA and CS6, and
impact dolphin monitoring (line-transect vessel survey method) covering NEL and
NWL when perimeter silt curtain under the Contract is completely removed and
vessel traffic numbers average 10 per month for Contract No. HY/2010/02. A
revised proposal has been updated and sent to IEC/ENPO for their further review
on 15 August 2017 and IEC/ENPO verified the revised proposal on 16 August 2017.
The revised proposal has been sent to authority by project team for review and
approval on 21 August 2017. The authority subsequently approved the proposal on
7 September 2017.
2.1.10
The Contract Specific EM&A Manual also required environmental site
inspections for air quality, noise, water quality, chemical, waste management,
marine ecology and landscape and visual impact.
2.2
Environmental Quality Performance (Action/Limit Levels)
2.2.1
The environmental quality performance limits (i.e. Action and/or Limit
Levels) of air and water quality monitoring were derived from the baseline air
and water quality monitoring results at the respective monitoring stations,
while the environmental quality performance limits of noise monitoring were
defined in the EM&A Manual.
2.2.2
The environmental quality performance limits of air quality, noise and
water monitoring are given in Appendix D.

5.1.7
Due to the commencement of marine work of the Expansion of Hong Kong
International Airport into a Three-Runway System
(3RS Project), a large portion of
works site boundary will be established at the northern
part of the existing airport Island. The recent arrangement of works boundary
of 3RS Project which delineates the boundary of the designated 3RS Project (for
the indicative 3RS boundary, please refer to Figure 5). The works area of
3RS project will affect several water quality monitoring stations and the
dolphin monitoring transect lines which are
being used for conducting monitoring under
Contract No. HY/2010/02. The EM&A Programme for the HZMB HKBCF
Project will therefore be affected. As a result, a proposal was prepared by ET
in September 2016 in accordance with condition 5.1 of EP-353/2009/K and
condition 4.1 of EP-354/2009/D, to relocate water quality monitoring stations
from SR5, IS10, CS(Mf)3 and alternate the transect lines of impact
dolphin monitoring 2, 3, 4, 5, 6 and 7. Comment was subsequently received
from IEC/ENPO. The comments were under ET¡¦s review in the reporting quarter. A
revised proposal has been updated and sent to IEC/ENPO for their further review
on 24 March 2017 and IEC/ENPO verified the revised proposal on the same date.
The revised proposal has been sent to authority by project team for review and
approval on 3 April 2017. The authority subsequently approved the proposal on
12 May 2017.
5.1.8
Due to substantial completion of marine works by the end of June 2017,
it is anticipated that the remaining construction works under Contract No.
HY/2010/02, which include ground investigation (GI) works, construction of
temporary timber platform, removal of jetty and reinstatement of seawall at the
western section, construction of outfall at the eastern seawall, would cause
limited disturbance to water column and not to the seabed. In view of this, a
proposal for change of EM&A programme/requirements was prepared by ET in
accordance with Condition 5.1 of EP-353/2009/K and Condition 4.1 of
EP-354/2009/D, to terminate water quality monitoring works at stations IS5,
IS(Mf)6, IS8, SR4(N), SR5(N), SR6, SR10A, SR10B(N), CS4, CSA and CS6, and
impact dolphin monitoring (line-transect vessel survey method) covering NEL and
NWL when perimeter silt curtain under the Contract is completely removed and
vessel traffic numbers average 10 per month for Contract No. HY/2010/02. A
revised proposal has been updated and sent to IEC/ENPO for their further review
on 15 August 2017 and IEC/ENPO verified the revised proposal on 16 August 2017.
The revised proposal has been sent to authority by project team for review and
approval on 21 August 2017. The authority subsequently approved the proposal on
7 September 2017.
5.1.9
After review, no floating grout production was in operation at any time
in reporting period for Contract No.HY/2010/02. Condition 3.26A of
EP-353/2009/K for Contract No.HY/2010/02 is complied with during the reporting

Recommendations on EM&A Programme
8.2.1
The impact monitoring programme for air quality, noise, water quality
and dolphin ensured that any deterioration in environmental condition was readily
detected and timely actions taken to rectify any non-compliance. Assessment and
analysis of monitoring results collected demonstrated the environmental impacts
of the Project. With implementation of recommended effective environmental
mitigation measures, the Project¡¦s environmental impacts were considered as
environmentally acceptable. The weekly environmental site inspections ensured
that all the environmental mitigation measures recommended were effectively
implemented.
8.2.2
The recommended environmental mitigation measures, as included in the
EM&A programme, effectively minimize the potential environmental impacts
from the Project. Also, the EM&A programme effectively monitored the
environmental impacts from the construction activities and ensure the proper
implementation of mitigation measures. No particular recommendation was advised
for the improvement of the programme.
8.3
Conclusions
8.3.1
The construction phase and EM&A programme of the Project commenced
on 12 March 2012.
8.3.2
For impact air quality monitoring, 1 action level exceedance of 24-Hour
TSP was recorded at AMS3B on 28 November 2017. After investigation, there is no
adequate information to conclude the recorded action level exceedances are
related to this Contract. No other 1-hour and 24-hour action and limit level
exceedances was recorded at all monitoring stations by Environmental Team of
Contract No. HY/2013/01 in the reporting period. For level of exceedance,
location and when exceedances were recorded, please refer to Appendix E of
monthly EM&A report of November 2017.
8.3.3
For construction noise, no exceedance was recorded at all monitoring
stations in the reporting quarter.
8.3.4
For water quality monitoring:
8.3.4.1
In September 2017, total of 82 action level exceedances for dissolved
oxygen and 4 limit level exceedances were recorded on 1, 6, 8, 11, 13, 15, 18,
22, 27 & 29 September 2017. 3 action level exceedances for turbidity were
recorded at IS(Mf)11 on 6 September and at IS10(N) & IS(Mf)11
on 8 September 2017 during flood tide. Total of 4 action level
exceedances for suspended solids were recorded at IS8, SR4(N) & SR6 on 6
September 2017 and at IS(Mf)11 on 8 September 2017 during flood tide, 1 limit
level exceedance was recorded on 8 September 2017 at IS10(N) during flood tide.
After investigation, it was concluded that those exceedance were unlikely
related to this Contract. No other exceedance was recorded at monitoring
stations in the reporting month. For level of exceedance, location and when
exceedances were recorded, please refer to Appendix E of monthly EM&A
report of September 2017.
8.3.4.2
In October 2017, 2 action level exceedances of suspended solids were
recorded at IS(Mf)11 and SR7 during flood tide on 20 October 2017. After
investigation, it was concluded that those exceedances were unlikely to be
contract related. No other exceedance was recorded at all monitoring stations
in the reporting month. For level of exceedance, location and when exceedances
were recorded, please refer to Appendix E of monthly EM&A report of October
2017.
8.3.4.3
In November 2017, 6 action level exceedances of suspended solids were
recorded at IS(Mf)11, IS(Mf)16 and SR7 during flood tide on 3, 6, 8 and 20
November 2017. After investigation, it was concluded that those exceedances
were unlikely to be contract related. No other exceedance was recorded at all
monitoring stations in the reporting month. For level of exceedance, location
and when exceedances were recorded, please refer to Appendix E of monthly
EM&A report November 2017.
8.3.5
For dolphin monitoring, dolphin monitoring results at all transects are
reported in the EM&A Report prepared for Contract No. HY/2013/01.
8.3.6
Environmental site inspection was carried out 14 times in the reporting
quarter. Recommendations on remedial actions were given to the Contractors for
the deficiencies identified during the site audits.
8.3.7
A complaint was forwarded to us by ENPO on 27 October 2017; the complainant
complained that yellowish muddy water was discharged into the sea from
construction site location C3 of the artificial island of the Hong
Kong-Zhuhai-Macao Bridge and this has been persist for one week. After
investigation, there is no adequate information to conclude the complaint is
related to this Contract.
8.3.8
A complaint was forwarded to us by ENPO on 23 November 2017; the
complainant complained that, on Hong Kong- Zhuhai-Macao Bridge Hong Kong
Boundary Crossing Facilities ¡V Artificial Island, due to watering was not
provided to all areas, large amount of fugitive dust was generated, especially
at the toll kiosks. After investigation, there is no adequate information to
conclude the complaint is related to this Contract.
8.3.9
No notification of summons or prosecution was received in the reporting
quarter.
8.3.10
Apart from the above mentioned monitoring, most of the recommended
mitigation measures, as included in the EM&A programme, were implemented
properly in the reporting quarter.
8.3.11
The recommended environmental mitigation measures effectively minimize
the potential environmental impacts from the Contract. The EM&A programme
effectively monitored the environmental impacts from the construction
activities and ensure the proper implementation of mitigation measures. No
particular recommendation was advised for the improvement of the programme.
