EM&A REQUIREMENTS
2.1.1
The Quarterly
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, noise
and the post-construction dolphin monitoring works for the Contract are covered
by Contract No. HY/2019/01 “Hong Kong-Zhuhai-Macao Bridge Hong Kong Boundary
Crossing Facilities – Phase 2 and Other Works”.
2.1.2
According to the
Contract Specific EM&A Manual, air quality monitoring at station AMS2,
AMS3C and AMS7B, and noise monitoring at station NMS2 and NMS3C are covered by
Contract No. HY/2019/01. It should be noted that the air quality monitoring at
station AMS6 is covered by Contract No. HY/2011/03. The ET of the Contract or
another ET of the HZMB project is required to conduct impact air quality
monitoring at AMS6 as part of EM&A programme if the impact air quality
monitoring work is no longer covered by Contract No. HY/2011/03 respectively.
However, this is subject to ENPO’s final decision on which ET should carry out
the monitoring work at these stations.
2.1.3
The most updated air and noise locations are
summarized in Table 2.1.
The locations of the air quality and noise monitoring stations shown in Figure 2 and Figure 3, respectively.
2.1.4
The remaining post-construction dolphin
monitoring works under Contract No. HY/2013/04 “HZMB HKBCF – Infrastructure
Works Stage II (Southern Portion)” were suspended from 1 March 2020. The ET of
Contract No. HY/2019/01 is required and continues the full implementation of
environmental monitoring commencing on 1 March 2020.
2.1.5
Currently, the role of dolphin monitoring and
data collection are still under Contract No. HY/2012/08 “Tuen
Mun-Chek Lap Kok Link –
Northern Connection Sub-sea Tunnel Section”. To avoid redundancy in the
monitoring effort, the findings of Contract No. HY/2012/08 were used for this
reporting month. The dolphin monitoring programme have adopted the standard
line-transect method (Buckland et al. 2001) to survey the pre-set and fixed
transect lines defined by AFCD in the Northeast Lantau (NEL) and Northwest
Lantau (NWL) survey areas.
