(a)
The in-situ water
quality parameters, viz. dissolved oxygen, temperature, salinity, turbidity and
pH, were measured by multi-parameter meters (i.e. Model YSI 6820 CE-C-M-Y) and
pH meter (i.e. Thermo Orion 230A+) respectively.
(a)
Digital Differential Global Positioning
Systems (DGPS) were used to ensure that the correct
location was selected prior to sample collection.
(b)
Portable,
battery-operated echo sounders were used for the determination of water depth
at each designated monitoring station.
(c)
All in-situ
measurements were taken at 3 water depths, 1 m below water surface, mid-depth and
1 m above sea bed, except where the water depth was less than 6 m, in which
case the mid-depth station was omitted. Should the water depth be less
than 3 m, only the mid-depth station was monitored.
(d)
At each
measurement/sampling depth, two consecutive in-situ monitoring (DO
concentration and saturation, temperature, turbidity, pH, salinity) and water
sample for SS. The probes were retrieved out of the water after the first
measurement and then re-deployed for the second measurement. Where the
difference in the value between the first and second readings of DO or
turbidity parameters was more than 25% of the value of the first reading, the
reading was discarded and further readings were taken.
(e)
Duplicate samples
from each independent sampling event were collected for SS measurement. Water
samples were collected using the water samplers and the samples were stored in
high-density polythene bottles. Water samples collected were well-mixed in the
water sampler prior to pre-rinsing and transferring to sample bottles. Sample
bottles were pre-rinsed with the same water samples. The sample bottles were
then be packed in cool-boxes (cooled at 4oC without being frozen),
and delivered to ALS Technichem (HK) Pty Ltd. for the analysis of suspended solids
concentrations. The laboratory determination work would be started within 24
hours after collection of the water samples. ALS Technichem (HK) Pty Ltd.
is a HOKLAS accredited laboratory and has comprehensive quality assurance and
quality control programmes. For QA/QC procedures, one duplicate samples of
every batch of 20 samples was analyzed.
(f)
The analysis
method and reporting and detection limit for SS is shown in Table 4.4.

Other relevant
data were recorded, including monitoring location / position, time, water depth,
tidal stages, weather conditions and any special phenomena or work underway at
the construction site in the field log sheet for information.
(a)
All in situ
monitoring instruments would be calibrated and calibrated by ALS Technichem
(HK) Pty Ltd. before use and at 3-monthly intervals throughout all stages of
the water quality monitoring programme. Calibration details are provided in Appendix E.
(b)
The dissolved
oxygen probe of YSI 6820 was calibrated by wet bulb method. Before the
calibration routine, the sensor for dissolved oxygen was thermally equilibrated
in water-saturated air. Calibration cup is served as a calibration chamber and
it was loosened from airtight condition before it is used for the calibration.
Calibration at ALS Technichem (HK) Pty Ltd. was carried out once every three
months in a water sample with a known concentration of dissolved oxygen. The
sensor was immersed in the water and after thermal equilibration, the known
mg/L value was keyed in and the calibration was carried out automatically.
(c)
The turbidity
probe of YSI 6820 is calibrated two times a month. A zero check in distilled
water was performed with the turbidity probe of YSI 6820 once per monitoring
day. The probe will be calibrated with a solution of known NTU at ALS
Technichem (HK) Pty Ltd. once every three months.

Air Quality
Impact
l
All working plants
and vessels on site should be regularly inspected and properly maintained to
avoid dark smoke emission.
l All
vehicles should be washed to remove any dusty materials before leaving the
site.
l Haul roads
should be sufficiently dampened to minimize fugitive dust generation.
l Wheel
washing facilities should be properly maintained and reviewed to ensure
properly functioning.
l Temporary
exposed slopes and open stockpiles should be properly covered.
l Enclosure
should be erected for cement debagging, batching and mixing operations.
l
Water
spraying should be provided to suppress fugitive dust for any dusty
construction activity.
l Regular
review and provide maintenance to dust control measures such as sprinkler
system.
Construction
Noise Impact
l Quieter powered mechanical equipment should
be used as far as possible.
l Noisy operations should be oriented to a
direction away from sensitive receivers as far as possible.
l Proper and effective noise control measures
for operating equipment and machinery on-site should be provided, such as
erection of movable noise barriers, enclosure for noisy plants or enhancement
works to provide sufficient acoustic decoupling measure(s). Closely check
and replace the sound insulation materials regularly
l Vessels and equipment operating should be
checked regularly and properly maintained.
l Noise Emission Label (NEL) shall be affixed
to the air compressor and hand-held breaker operating within works area.
l Acoustic decoupling measures should be
properly implemented for all existing and incoming construction vessels with
continuous and regularly checking to ensure effective implementation of
acoustic decoupling measures.
Water
Quality Impact
l
Regular review and
maintenance of silt curtain systems, drainage systems and desilting facilities
in order to make sure they are functioning effectively.
l
Construction of
seawall should be completed as early as possible.
l
Regular inspect and
review the loading process from barges to avoid splashing of material.
l
Silt, debris and
leaves accumulated at public drains, wheel washing bays and perimeter
u-channels and desilting facilities should be cleaned up regularly.
l
Silty effluent
should be treated/ desilted before discharged. Untreated effluent should be
prevented from entering public drain channel.
l
Proper drainage
channels/bunds should be provided at the site boundaries to collect/intercept
the surface run-off from works areas.
l Exposed slopes and stockpiles should be covered up properly during
rainstorm.
Chemical and
Waste Management
l

[1] A noteworthy observation is
to show that either the conduct of the surveys themselves is affected, i.e.,
the noted vessel or works impedes the progress or view of the survey platform.
In addition, the vessel or construction works may be different or additional to
that observed previously and further, are of such a nature that they are a
likely to create an impact on the movement or behaviour of the subject of the
impact survey, in this case, the dolphins.
