NOISE
2.1.
MONITORING REQUIREMENTS
To ensure no adverse noise impact, noise
monitoring is recommended to be carried out within 300m radius from the nearby
noise sensitive receivers (NSRs), during construction phase. The NSRs selected
as monitoring station are (i) NSR4 - Creative Secondary
School, (ii) NSR24 - PLK Laws Foundation College, and (iii) NSR31 - School of
Continuing and Professional Studies - CUHK respectively.
In accordance with the EM&A Manual,
baseline noise level at the noise monitoring stations were established as presented
in the Baseline Monitoring Report. Impact noise monitoring will be conducted
once per week in the form of 30-minutes measurements Leq,
L10 and L90 levels recorded at each monitoring station between 0700 and 1900
hours on normal weekdays.
Referring to EM&A manual Section 4.1.2,
the impact noise monitoring should be carried out at all the designated
monitoring stations when there are project-related construction activities
undertaken within a radius of 300m from the monitoring stations.
No impact monitoring for noise impact was
conducted in the reporting period due to the overly distant monitoring station
from the works location, where they were farther than 1 km from the closet
monitoring station NSR4 to the works location.
Construction noise level measured in terms
of the A-weighted equivalent continuous sound pressure level (LAeq).
Leq 30min was used
as the monitoring parameter for the time period between 0700 and 1900 hours on normal weekdays. Table 2.1 summarizes the monitoring parameters, frequency and
duration of the impact noise monitoring.

WATER QUALITY
In accordance with the
recommendations of the EIA, water quality EM&A is required during dredging
for the submarine pipelines and, during operation phase. In addition, baseline
water quality monitoring will be required prior to the commencement of marine
construction activities. The following Section provides details of the water
quality monitoring to be undertaken by the Environmental Team (ET) to verify
the distance of sediment and brine plume dispersion and to identify whether the
potential exists for any indirect impacts to occur to ecological sensitive
receivers. The water quality monitoring programme
will be carried out to allow any deteriorating water quality to be readily
detected and timely action taken to rectify the situation. The status and
locations of water quality sensitive receivers and the marine works location
may change after issuing this Document. If required, the ET in consultation
with IEC will propose updated monitoring locations and seek
approval from EPD.
Water quality monitoring for the Project can
be divided into the following stages:
-
Dredging
activities during construction phase;
-
Discharge
of effluent from main disinfection during construction phase;
-
Operation
phase - first year upon commissioning; and,
-
Continuous
monitoring of effluent quality.
In addition, the marine
works contractor is required to complete a silt curtain efficiency test for the
combined use of floating silt curtain type and cage type silt curtain for
dredging at seawater intake to confirm the silt curtain reduction efficiency
assumptions of the assessment. The details of testing plan together with the
silt curtain deployment plan updated testing plan shall be submitted by the ET
to seek approval from the IEC and EPD.

control and mitigation measures under the Contract.
Joint site inspection with IEC was carried
out on a bi-weekly basis.
Minor deficiencies were
observed during weekly site inspection. Key observations during the site
inspections are summarized below:
-
Prevention
actions for oil/chemical spillage were not carried out properly
-
Dust
suppression mitigation measures were not implemented properly
The Contractor has rectified
the observations identified during environmental site inspections in the
reporting period.
According to the EIA Study Report,
Environmental Permit, contract documents and EM&A Manual, the mitigation
measures detailed in the documents are implemented as much as practical during
the reporting period. An updated Implementation Status of Environmental
Mitigation Measures (EMIS) is provided in Appendix C.
8. CONCLUSIONS AND RECOMMENDATIONS
This is the 2nd Quarterly
EM&A Report for the Project which summarizes the key findings of the
EM&A programme during the reporting period from 1
Jun to 31 Aug 2020, in accordance with the EM&A Manual and the requirement
under FEP-01/503/2015/A.
No noise monitoring was conducted in the
reporting period due to the over distant monitoring station from the works
location.
The baseline water monitoring had been conducted
between 12 May 2020 to 6 Jun 2020 at the thirteen designated monitoring
stations and the six designated monitoring at waters near TKO. No impact water
quality monitoring was conducted in the reporting period since the commencement of marine construction and
dredging activities for the Project are scheduled in November 2020 the
earliest.
No
project-related exceedance of the Action / Limit Level was recorded during the
reporting period.
Weekly environmental site
inspection was conducted during the reporting period. Minor deficiency was
observed during site inspection and was rectified. The environmental
performance of the project was therefore considered satisfactory.
According to the environmental site
inspections performed in the reporting period, the Contractor is reminded to
pay attention on maintaining proper materials
storage.
No
environmental complaint was received in the reporting period.
No notification of summons or prosecution
was received since commencement of the Contract.
The ET will keep track on
the construction works to confirm compliance of environmental requirements and
the proper implementation of all necessary mitigation measures.
