(*) During
the whole reporting period, water sampling was unable to carry out at WM2B and WM2B-C due to shallow
water (water depth under 150mm)
Breaches
of Action/Limit levels
ES.03. In the
Reporting Period, no noise exceedance and
valid noise complaint was registered for construction noise. For air quality, there were
6 Action Level exceedances of 24-hour TSP monitoring results recorded. For water quality monitoring, a total of 26 Action/ Limit Level exceedance were recorded. The summary of exceedance
for the Reporting Period is shown below.

• 6
numbers of LL
exceedances which
recorded on 6,
11, 15 Dec 17 were related to the insufficient mitigation measures for
Contract 3. • Other
20 numbers of exceedances
were not project related. |
The Contractor
was reminded to implement water quality mitigation measures in accordance
with ISEMM of the EM&A Manual requirements |

ES.04. Investigation Reports for all 24-hour TSP exceedances were completed by
ET which concluded that the exceedances were not project related. According to the observation during site
audit, the Contractor had properly implemented the dust mitigation measures
such as provided water spraying on construction area and site haul road regularly. Moreover, water tanker and road sweeper
were deployed the main road on regular basis to suppress fugitive dust and
remover dirt and debris on road. It
was considered that the exceedances were likely related to the dust impact
from traffic.
ES.05. Investigation Reports for all water quality exceedances were completed by ET.
The investigation result revealed that the LL exceedances on 6, 11, 15 December
2017 were related to the insufficient water quality mitigation measures for
Contract 3 while the other exceedances was not
project-related. As remedial action,
the relevant Contractor had enhanced the water quality mitigation measures such as
covering the exposed area by tarpaulin sheet to minimize muddy runoff and no
project-related exceedance was recorded after the enhancement measures.
Environmental
Complaint
ES.06. In this Reporting Period, four (4) documented environmental complaint was received
regarding the air quality and noise issues under the EM&A Programme. Subsequent joint site inspection was carried
out for complaint investigation and investigation
reports were submitted by ET after reviewed by IEC. The IRs revealed that the Contractors
have properly implemented the mitigation measures and no breaches of EM&A programme was seen.
Further enhancement measures were included and implemented in response
to the complaint.
Notification of Summons and Successful Prosecutions
ES.07. No environmental summons or successful
prosecutions were recorded in the Reporting Period.
Reporting Changes
ES.08. No reporting
changes were made in the Reporting Period.
Future key issues
ES.09. During dry
season, special attention should be paid on the potential construction dust
impact since most of the construction sites are adjacent to villages. The
Contractor should fully implement the construction dust mitigation measures as appropriately.
ES.10. Preventive
measures for muddy water or other water pollutants from site surface flow to local
stream such as Kong Yiu Channel, Ma Wat Channel, Ping Yuen River, Kwan Tei River or public area should be
properly maintained. The
Contractors should paid special attention on water quality mitigation measures and
fully implement according ISEMM of the EM&A Manual, in particular for
working areas near Ma Wat Channel and Ping Yuen River.
ES.11. In
addition, all effluent discharge shall be ensure to fulfill Technical
Memorandum of Effluent Discharged into Drainage and Sewerage Systems, inland
and Coastal Waters criteria or discharge permits stipulation.
ES.12. Construction
noise would be a key environmental issue during construction work of the
Project. Noise mitigation measures
such as using quiet plants should be implemented in accordance with the
EM&A requirement.
