Air Quality
5 sets of 1-hr & 24-hr TSP
construction dust measurement were carried out at each monitoring stations
during normal weekdays of the reporting period. No Action / Limit Level
exceedance for 1-hr & 24-hr TSP impact monitoring was recorded during the
period.
Noise
4 sets of 30-minute construction noise
measurement were carried out at each monitoring stations during normal weekdays
of the reporting period. No exceedance of Action and Limit Levels of
construction noise was recorded during the reporting period.
Groundwater
Site clearance of future landfilling area
is in progress. The installation of groundwater monitoring boreholes will be
installed after the site formation work of the landfilling area. The target
commencement period of groundwater monitoring will be in 2026. No groundwater
monitoring is required before the completion of site formation work of the
landfilling area.
Surface Water Quality
1 set of surface water quality measurement
were carried out at each monitoring stations during normal weekdays of the
reporting period. No exceedance of Action and Limit Levels of surface water
quality at each monitoring stations was recorded during the reporting period.
Landfill Gas
27 sets of landfill gas measurement were
carried out at the designated monitoring locations during normal weekdays of
the reporting period. No exceedance of Action and Limit Levels of landfill gas
was recorded during the reporting period.
Landscape and Visual
All the specified and affected LCAs, LRs
and VSRs have been monitored during the reporting period. No exceedance of
Action and Limit Levels of landscape and visual was recorded during the
reporting period.
Cultural Heritage
Implementation of the mitigation measures
during construction phase of the Project has been monitored through the regular
site inspection/audit.
Ecology
Implementation of the mitigation measures
during construction phase of the Project has been monitored through the regular
site inspection/audit.
Environmental Site Inspection
4 weekly environmental site inspections
were carried out during the reporting period. A joint environmental site
inspection was carried out by the representatives of the Employer's
Representative (ER), the Contractor, IEC and the ET on 19 August 2024. The
Contractor has generally implemented part of the mitigation measures as
recommended. No site inspection was conducted by Environmental Protection
Department-Regional Office (North) (EPD-RNG) during the reporting period.
3.1.1.1
In accordance with the EM&A Manual, 1-hr & 24-hr Total Suspended
Particulates (TSP) levels should be measured at the designated air quality
monitoring stations in every 6 days to ensure that any deteriorating air
quality could be readily detected, and timely action shall be undertaken to
rectify such situation. For 1-hr TSP monitoring, the sampling frequency of at
least three times in every six-days should be undertaken when the highest dust
impact occurs. The specific time to start and stop the 24- hr TSP monitoring
shall be clearly defined for each location.
3.1.2 Monitoring Parameters, Frequency and Location
3.1.2.1
According to the EM&A
Manual, three monitoring stations namely AM(D)1, AM(D)2 and AM(D)3 are selected
for the impact monitoring.
3.1.2.2 A baseline monitoring plan has been submitted to IEC and EPD on 31 May 2022 including the proposal with justification of change of monitoring locations. Due to limited access to the original monitoring locations at AM(D)1, AM(D)2 and AM(D)3, the adjusted stations at AM1, AM2 and AM3 were agreed with IEC prior to the baseline and impact monitoring. The locations of adjusted dust monitoring locations are shown in Figure 2.
3.1.2.3 The detailed monitoring schedule is shown in Appendix D. The locations of dust monitoring stations are shown in Table 3-1. The monitoring parameters, frequency and duration are shown in Table 3-2.

Remarks:
The contractor passed
correspondence including original monitoring locations specified on the Approved
EM&A Manual to the village representatives on 26 April 2022. After a
meeting with Ta Kwu Ling District Rural Committee (RC) Chairman, representative
from the RC and a few villagers on 1 May 2022, all the Village Heads of Wo Keng
Shan Tsuen, Heung Yuen Wai and Lin Ma Hang verbally refused to accept our
proposal for installation of dust and / or noise monitoring equipment within or
next to their villages, for the baseline & impact monitoring.
AM(D)1
Tung Lo Hang, AM(D)2 Heung Yuen Wai, AM(D)3 Wo Keng Shan Tsuen are the air
monitoring stations for the construction phase EM&A programme as identified
in the approved EM&A Manual for the Project. The access to Tung Lo Hang,
Heung Yuen Wai and Wo Keng Shan Tsuen were denied. A search for alternative air monitoring
locations (AM1, AM2 & AM3) was carried out during the site visit.
The
Baseline Monitoring Plan has been submitted to IEC and EPD including the
proposal of change of monitoring locations on 31 May 2022. This arrangement
was conducted between baseline and impact monitoring and has been agreed by the
Independent Environmental Checker (IEC) and no comment received from EPD.
Due
to the adjustment of the location of AM(D)1, AM(D)2 & AM(D)3to AM1, AM2
& AM3, the measured air quality levels at AM1, AM2 & AM3 would
represent the air quality levels at AM(D)1, AM(D)2 & AM(D)3.

3.1.3.1 High volume samplers (HVSs) were used for carrying out 24-hr TSP monitoring. For 1-hr TSP monitoring, direct reading dust meters were used to measure 1-hr TSP levels.
