sought. However, approvals for
carrying out impact monitoring works within their premises were not obtained.
Impact air quality monitoring was conducted at site boundary of the site office
area in Works Area WA2 (AMS3B) respectively. Same baseline and Action Level for
air quality, as derived from the baseline monitoring data recorded at Ho Yu
College, was adopted for this alternative air quality location.
2.1.3
For impact noise
monitoring, monitoring locations NMS2 (Seaview Crescent Tower 1) was set up at
the proposed locations in accordance with Contract Specific EM&A Manual.
However, for monitoring location NMS3 (Ho Yu College), as proposed in the
Contract Specific EM&A Manual, approval for carrying out impact monitoring
could not be obtained from the principal of the school. Permission on setting
up and carrying out impact monitoring works at nearby sensitive receivers, like
Caribbean Coast and Coastal Skyline, was also sought. However, approvals for carrying out
impact monitoring works within their premises were not obtained. Impact noise
monitoring was conducted at site boundary of the site office area in Works Area
WA2 (NMS3B) respectively. Same baseline noise level, as derived from the
baseline monitoring data recorded at Ho Yu College was adopted for this
alternative noise monitoring location. Reference is made to ET’s proposal of
relocation of air quality monitoring station (AMS7) dated on 2 February
2015, with no further comment received from IEC on 2 February 2015 and no
objection received from EPD on 5 February 2015, the impact air quality
monitoring station AMS7 (Hong Kong SkyCity Marriott Hotel) has been relocated
to AMS7A (Chu Kong Air-Sea Union Transportation Company Limited) on 3 February
2015. Action Level for air quality, as
derived from the baseline monitoring data recorded at Hong Kong SkyCity Marriott Hotel, was adopted for this alternative air quality location.
2.1.4 As informed by the premises owner of (AMS7A) - Chu Kong
Air-Sea Union Transportation Co. LTD would not grant us the permission to
install air quality monitoring equipment (High volume sampler) and conduct
1-hour TSP/24 hour TSP monitoring at the premises of Chu Kong Air-Sea Union
Transportation Co. LTD after December 2015. In order to fulfil the EM&A
requirement of this Contract, as permission to conduct impact air quality
monitoring at the premise of Hong Kong SkyCity Marriott Hotel has been granted

December 2015 was conducted before the relocation of AQM Station from AMS7A to
AMS7. The impact air quality monitoring has been conducted at AMS7 (Hong Kong
SkyCity Marriott Hotel) since 1 January 2016, Action Level for air quality, as
derived from the baseline monitoring data recorded at Hong Kong SkyCity
Marriott Hotel will be adopted for this air quality monitoring location.
2.1.5 In accordance with the Contract Specific EM&A Manual,
twenty-one stations were designated for impact water quality monitoring. The
nine Impact Stations (IS) were chosen on the basis of their proximity to the
reclamation and thus the greatest potential for water quality impacts, the
seven Sensitive Receiver Stations (SR) were chosen as they are close to the key
sensitive receives and the five Control/ Far Field Stations (CS) were chosen to
facilitate comparison of the water quality of the IS stations with less
influence by the Project/ ambient water quality conditions.
2.1.6 Due to safety concern and topographical condition of the
original locations of SR4 and SR10B, alternative impact water quality
monitoring stations, naming as SR4(N) and SR10B(N), were adopted, which are
situated in vicinity of the original impact water quality monitoring stations
(SR4 and SR10B) and could be reachable. Same baseline and Action Level for
water quality, as derived from the baseline monitoring data recorded, were
adopted for these alternative impact water quality monitoring stations.
2.1.7 The monitoring locations used during the reporting quarter
are depicted in Figures 2, 3 and 4
respectively.
2.1.8 The Contract Specific EM&A Manual also required
environmental site inspections for air quality, noise, water quality, chemical,
waste management, marine ecology and landscape and visual impact.

actions:
1: Review of the information and
provided by the complainant
2: Review the work activities
conducted by Contract HY/2010/02 HKBCF Reclamation on 16 July 2016.
3. Review site condition
7.1.2.2 Investigation
results:
- The
photo provided by the complainant was reviewed and it shows that marine litter
floating on sea near Tuen Mun Ferry Pier.
- Information provided by the
Contractor was checked, marine activities being conducted by Contract
HY/2010/02 on 16 July 2016 were accroprode/rock-fill placement for the
construction of the seawall by using a pelican with mechanical grab. In
addition, since the location of Tuen Mun Ferry Pier is approximately 5km away
from the active works contract HY/2010/02, these construction activities are
unlikely related to the floating litter on sea observed near Tuen Mun Ferry
Pier on 16 July 2016.
- Joint
site inspection was also conducted on 21 July 2016 with the Contractor, IEC, ET
and RSS. No litter was observed on sea during the inspection of the perimeter
of HKBCF reclamation works.
- As
such, it is considered the marine litter floating near the Tuen Mun Ferry Pier
is unlikely to be related to this Contract.
