Remarks:
(1) The air quality monitoring works at AMS2 were
conducted by the ET of Contract No. HY/2013/01 from 1 Sep 2017 to 30 Sep 2018.
The air quality monitoring works for the Contract at AMS2 are covered by
Contract No. HY/2013/04 since 1 Oct 2018.
(2)
For the monitoring location
AMS3 (Ho Yu College), as proposed in the Updated EM&A Manual for HKBCF
(Version 1), approval for carrying out impact monitoring could not be obtained
from the principal of the school. Alternative monitoring location at AMS3B was
proposed. The air quality monitoring works at AMS3B were conducted by the ET of
Contract No. HY/2013/01 from 1 Sep 2017 to 19 Aug 2018.
(3)
The air quality monitoring
station at AMS3B was relocated and renamed as AMS3C. The air quality monitoring
works at AMS3C are covered by Contract No. HY/2013/04 since 20 Aug 2019.
(4)
Same baseline and Action
Level for air quality, as derived from the baseline monitoring data recorded at
AMS3 - Ho Yu College/ AMS7 - Hong Kong SkyCity
Marriott Hotel were adopted for these alternative air quality locations.
(5)
The air quality monitoring
works at AMS6 were covered by Contract No. HY/2011/03 - Hong Kong-Zhuhai-Macao
Bridge Hong Kong Link Road ¡V Section between Scenic Hill and HKBCF during the
reporting period.
(6)
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.
(7)
The air
quality monitoring works for the Contract at AMS7/AMS7A were covered by the
Contract No. HY/2010/02 from 26 Sep 2014 to 31 Aug 2017. The air quality monitoring
works at AMS7B were conduct by the ET of Contract No. HY/2013/01 from 6 Feb 2018 to 30 Sep 2018; and are covered by
Contract No. HY/2013/04 since 1 Oct 2018.
(8)
The noise
monitoring works at NMS2 were covered by Contract No. HY/2010/02 from 26 Sep
2014 to 31 Aug 2017; and were conducted by the ET of Contract No. HY/2013/01 from 1 Sep 2017 to 30 Sep 2018; and are covered by
Contract No.
HY/2013/04 since 1 Oct 2018.
(9)
The noise
monitoring works NMS3B were covered by Contract No. HY/2010/02 from 26 Sep 2014
to 31 Aug 2017; and were conducted by the ET of Contract No. HY/2013/01 from 1 Sep 2017 to 19 Aug 2018.
(10) The noise monitoring works at NMS3C are covered by
Contract No. HY/2013/04 since 20 Aug 2018.
(11) 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. |

Remarks:
^ Alternative water quality monitoring stations at SR3,
SR10A and SR10B(N) were justified by the ET Leader on 8 November 2017 and
verified by IEC on 13 November 2017; and submitted to EPD on 29 November 2017
and it was approved by EPD on 22 December 2017.
*Only mid-depth of DO were monitored at SR3 during
mid-ebb tide during baseline monitoring.
(1) The impact mean of dissolved oxygen levels from
1 September 2017 to 30 September 2018 are calculated using monitoring data in
