noise mitigation measures, such as use of noise barrier and additional
acoustic mat on DCM barges and vibratory hammer to further reduce noise
nuisance to nearby residents. The Contractor was reminded
to implement all relevant mitigation measures outlined in the EIA Report
and EM&A Manual and additional noise mitigation measures. The
ET will continue to check the implementation status of the mitigation
measures.
Based
on the information provided by the ER and the Contractor, the noise nuisance
and light disturbance were generated by an one-time event due to unforeseen
incident, the Contractor was reminded
to implement noise mitigation measures and review the working sequence
to reduce noise nuisance and light disturbance to nearby residents. The
ET will continue to check the implementation status of the mitigation
measures.

Portable direct reading dust
meters were used to measure 1-hour TSP levels in undertaking the air quality
monitoring for the Project. The proposed use of portable direct reading
dust meters was submitted to IEC and obtained agreement from the IEC as stated
in Section 5.5 of the Updated EM&A Manual. With the use of direct
reading dust meter, it can allow prompt and direct results for the EM&A
reporting and the implementation of the event and action plan. The
portable direct reading dust meter would be calibrated every year against High Volume Sampler
(HVS) to check
the validity and accuracy of the results measured by direct reading method.
The monitoring location and
equipment
used in the
impact air
quality monitoring programme are summarized in Table 2.2 and illustrated in Figure 2.1. Copies of the
calibration certificates for the equipment are presented in Annex D1,
which showed that the portable direct reading dust meter is capable of
providing comparable results with that provided by a HVS.

Action
|
The
exceedance was not considered as caused by the construction of the Project
due to the following reasons:
Ÿ
Areas of
reclamation related marine works undertaken under the Project were surrounded
by silt curtain, which was inspected daily by the Contractor and inspected
periodically by ER and observed overall to be in good condition and
functioning well.
Ÿ The monitoring
station is located further away from the works area when compared with
monitoring stations TCE-WQM1 and TCE-WQM4 where exceedances were not
recorded.
|
Based on the preliminary investigation
conducted for each of the monitoring day with potential action level exceedance
with the Contractor, the ER and the IEC, there is no evidence showing the
exceedance was related to the Project. Nevertheless,
the Contractor was reminded to implement all relevant mitigation measures for
the marine works, including regular checking of silt curtain integrity and
maintain good site practice. The ET will keep on checking monitoring
data, plant, equipment and Contractorˇ¦s working methods. The ET will also
conduct further investigation, including the review of water quality monitoring
data from adjacent projects, to substantiate the exceedances were not
considered as caused by the construction of the Project.
No impact
soft shore ecological monitoring at Tung Chung Bay and Tai Ho Wan was scheduled
during the reporting period. The impact soft shore ecological monitoring
at Tung Chung Bay and Tai Ho Wan is scheduled to be conducted in March 2019 in
accordance with the Updated EM&A Manual.
