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 month 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.
Impact noise monitoring will be conducted weekly in the reporting period between 0700-1900
hours on normal weekdays. No construction works were carried out during 1900-0700 hours in all
days or any time on Sundays or general holidays during the reporting period.
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.
3.1. IMPACT MONITORING METHODOLOGY
3.1.1. WATER QUALITY PARAMETERS
The parameters that have been selected for measurement in situ and in the laboratory are those
that were either determined in the EIA to be those with the most potential to be affected by the
construction works or are a standard check on water quality conditions. Parameters to be
measured in the baseline monitoring are listed in Table 3.1.

3.1.6. SAMPLING FREQUENCY
During periods when there are dredging works, impact monitoring should be undertaken at the
monitoring stations as shown in Figure 3.1 and Table 3.3 three days per week during the
construction phase after the commencement of marine construction works and dredging activities.
Monitoring at each station would be undertaken at both mid-ebb and mid-flood tides on the same
day. The tidal range selected for the baseline monitoring will be at least 0.5 m for both flood and
ebb tides as far as practicable. The interval between two sets of monitoring would not be less than
36 hours. The monitoring frequency would be increased in the case of exceedances of Action/Limit
Levels if considered necessary by ET. Monitoring frequency would be maintained as far as
practicable.
The monitoring location/position, time, water depth, water temperature, salinity, weather
conditions, sea conditions, tidal stage, special phenomena and work underway at the marine works
site will be recorded.
3.1.7. SAMPLING DEPTHS & REPLICATION
For baseline monitoring, each station will be sampled and measurements/ water samples will be
taken at three depths, 1 m below the sea surface, mid-depth and 1 m above the seabed. For stations
that are less than 3 m in depth, only the mid depth sample shall be taken. For stations that are less
than 6 m in depth, only the surface and seabed sample shall be taken. For in situ measurements,
duplicate readings shall be made at each water depth at each station. Duplicate water samples shall
be collected at each water depth at each station.
3.2. MONITORING PROGRAMME
The commencement of marine construction and dredging activities for the Project are scheduled in
November 2020 the earliest. The ET of the Project will conduct the baseline water monitoring
before the commencement of marine construction and dredging activities at the thirteen designated
monitoring stations and the six designated monitoring at waters near TKO in accordance with the
EM&A Manual and Contract Specification respectively. The impact water monitoring shall be
scheduled after the commencement of marine construction and dredging activities. Hence, no water
monitoring was conducted during the reporting month.
