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).
The air quality, noise, water quality and dolphin monitoring works under
Contract HY/2013/01 “HZMB HKBCF – Passenger Clearance Building were suspended
from 1 October 2018. The ET of Contract No. HY/2013/04 is required and
continues the same implementation of environmental monitoring commencing on 1
October 2018. It should be noted that the air quality monitoring station (AMS6) is covered by Contract No. HY/2011/03 Hong
Kong-Zhuhai-Macao Bridge Hong Kong Link Road – Section between Scenic Hill
and HKBCF. If the impact air quality monitoring at AMS6
is no longer covered under Contract No. HY/2011/03, it is required to continue
such monitoring at AMS6 as part of EM&A programme. However, this is subject to ENPO’s final
decision on which ET should carry out the monitoring work at these stations.

Remarks:
(1)
The original monitoring
location was at Hong Kong SkyCity Marriott Hotel
(AMS7). As the permission to carry out air quality monitoring at Hong Kong SkyCity Marriott Hotel was not granted after 31 January
2015, the monitoring location was relocated to Chu Kong Air-Sea Union
Transportation Co. Ltd. (AMS7A) from 5 February 2015 to 30 December 2015. The
alternative monitoring location at Chu Kong Air-Sea Union Transportation Co.
Ltd. was approved by EPD on 5 February 2015. However, AMS7A was relocated back
to its original location (AMS7-Hong Kong SkyCity
Marriott Hotel) on 30 December 2015. The relocation of air quality monitoring
location, AMS7A, back to AMS7 was approved by EPD on 21 December 2015. As the
permission to carry out air quality monitoring at Hong Kong SkyCity
Marriott Hotel was not granted after the end of January 2018, as such, a
proposal for the monitoring location relocated to 3RS Site Office(AMS7B) was
justified by the ET Leader for Contract No. HY/2013/01 on 22 January 2018;
verified by the IEC on 24 January 2018; and submitted to EPD on 30 January
2018, and the AQM has been carrying out at AMS7B with EPD’s consent since 6
February 2018.

Remarks: (a)
* Due to
the presence of deployed silt curtain systems at the site boundaries of the Contract, some of the transect lines could not be fully surveyed during the regular survey.
Transect 10 is reduced from 6.4km to approximately 3.6km in length due to the
HKBCF construction site. Therefore, the total transect length for both NEL
and NWL combined is reduced to approximately 108km. (b)
#
Coordinates for transect lines 1, 8,
9 and 11 have been updated in respect to the Proposal for Alteration of
Transect Line for Dolphin Monitoring approved by EPD on 19 August 2015. (c) Due to marine work of the Expansion of Hong Kong
International Airport into a Three-Runway System (3RS Project), original
transect lines of dolphin monitoring 2, 3, 4, 5, 6 and 7 are enclosed by
works boundary of 3RS Project. Alternative dolphin monitoring transect lines 2, 3, 4, 5, 6, 7 and 24 are adopted
starting from 17 May 2017 to replace the original transect lines. (d)
The
change of transect lines 2, 3, 4, 5, 6 and 7 and new vessel-based transect
line 24 for dolphin monitoring have been proposed due to the marine work of a
designated project - Expansion of Hong Kong International Airport into a
Three-Runway System (3RS Project). It was justified and verified by the ET
Leader for Contract No. HY/2010/02 and the IEC respectively on 24 March 2017
and it was approved by EPD on 12 May 2017. |
