Remarks:
(1)
The ET of this
Contract should conduct impact air quality monitoring at the Air Monitoring
Station listed in the table as part of EM&A programme
according to the latest notification from ENPO when the monitoring station(s)
is/are no longer covered by another ET of the HZMB project.
(2)
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.
(3) The ET of this Contract should conduct impact noise
monitoring at the NMS listed in the table as part of EM&A programme according to the latest notification from ENPO
when the monitoring station(s) is/are no longer covered by another ET of the
HZMB project.
(4)
The Action
and Limit Levels for schools will be applied for this alternative monitoring
location.

Remarks: (a) * Due to the presence of deployed
silt curtain systems at the site boundaries of the Contract, some of the
transect lines shown in Figure 5.1 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)
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. (d)
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. |
