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

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 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 12May 2017. (d)
Due to marine work ofthe 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. |

Remark: (^) Alternative water quality monitoring stations at SR3, SR10A
and SR10B(N) were justified and justified by the ET Leader on 8 November 2017
and the IEC verified on 13 December 2017 and it was approved by EPD on 22
December 2017.
