Monitoring
3.5.11 Water
quality parameters include dissolved oxygen, water
temperature & depth, turbidity, salinity, pH and stream flow velocity shall
be measured in-situ, and suspended solids shall be analyzed by a HOKLAS-accredited
testing laboratory.
Dissolved Oxygen and Temperature Measurement
3.5.12 The dissolved oxygen (DO) measuring
instruments should be portable and weatherproof. The equipment should also
complete with cable and sensor, and DC power source. It should be capable of
measuring:
• A DO level
in the range of 0 – 20 mg/L and 0 – 200% saturation; and
• A temperature of 0 – 45 degree Celsius.
3.5.13
The
equipment should have a membrane electrode with automatic temperature
compensation complete with a cable.
3.5.14
Should
salinity compensation not be built-in to the DO equipment, in-situ salinity
should be measured to calibrate the DO measuring instruments prior to each
measurement.
Turbidity Measurement
3.5.15
The turbidity measuring instruments should be
a portable and weatherproof with DC power source. It should have a photoelectric sensor
capable of measuring turbidity level between 0–1000 NTU (for example, Hach model 2100Q or an
approved similar instrument).
Salinity Measurement
3.5.16
A portable salinometer
capable of measuring salinity in the range of 0–40 parts per thousand (ppt) should be provided for measuring salinity of the water
at each monitoring location.
pH Measurement
3.5.17
A portable pH meter capable of measuring a
range between 0.0 and 14.0 should be provided to measure pH under the specified
conditions accordingly to the APHA Standard Methods.
Water Depth Measurement
3.5.18
A portable, battery-operated echo sounder or
an approved similar instrument should be used for water depths determination at
each designated monitoring station.
Stream Flow Velocity Equipment
3.5.19
Since the EM&A Manuals do not specified instrument to use
stream flow velocity measurement, the monitoring of stream flow velocity is
therefore proposed to be conducted by using a flow probe which is a digital
water velocity meter.
Water Sampling Equipment
3.5.20
A water sampler is required for suspended
solid (SS) monitoring. A water sampler e.g. Kahlsico Water Sampler, which is a transparent PVC cylinder
with capacity not less than 2 litres, will be used
for water sampling if water depth over than 0.5m.
3.5.21
For sampling from very shallow water depths e.g. <0.5 m, water
sample will be collected from water surface below 100mm using plastic bottle to avoid
inclusion of bottom sediment or humus.
Moreover, Teflon/stainless steel bailer or self-made sampling buckets
maybe used for water sampling. The
equipment used for sampling will be depended the sampling location and depth
situations.
Sample Containers and Storage
3.5.22
Water samples for suspended solid should be
stored in high density polythene bottles with no preservative added, packed in ice
(cooled to 4°C without being frozen) and delivered to the laboratory within 24
hours of collection and be analyzed as soon as possible after collection.
3.5.23 Analysis of suspended solids should
be carried out in a HOKLAS or other accredited laboratory. Water samples of
about 1L should be collected at the monitoring stations for carrying out the

The
meteorological data during the impact monitoring days are summarized in Appendix J.
4.2.1
As
shown in Table 4-1, the monitoring results of 24-hour and 1-hour TSP monitoring in the Reporting Month were well below the Action Level. No Notification of Exceedance (NOE) of air quality monitoring criteria was issued and therefore corrective action was not required.
5.1.1
Noise impact monitoring schedule was submitted to
relevant party on 24 August 2018 and shown in Appendix G.
5.1.2
In
this Reporting
Month, 4
occasions of noise monitoring were undertaken at designated noise monitoring
location CN-1. The sound level were set in a free field situation, and therefore a façade correction of +3dB(A)
has been added according to acoustical principles and EPD guidelines. Since the distance of current construction works of Contract 1 over 300m from CN-2,
noise monitoring was not performed at that
location in this Reporting Month. The monitoring result of noise monitoring is show in Table 5-1 and the
graphical plots are shown in Appendix I.

(*) A façade correction of +3dB(A) has
been added according to acoustical principles and EPD guidelines.
5.1.3
Prior and after noise monitoring, the accuracy of the sound level meter
has been checked by
an acoustic calibrator to
ensure the measurement within acceptance range of ±0.5dB. Moreover, wind speed checked
by portable wind speed meter has
been performed before noise monitoring. No
noise measurement was performed in fog, rain, wind with a steady speed
exceeding 5 m s-1 or wind with gusts exceeding 10 m s-1.
5.2.1
As
shown in Table 5-1, no noise monitoring results exceeded the Limit Level in the Reporting Month. No Notification of Exceedance (NOE) of
construction noise criterion was issued and no corrective action was therefore required.

Water Quality
6.1.1
Water quality impact monitoring schedule was submitted to relevant
party
on 30
July 2018 and shown in
Appendix G.
6.1.2
In the Reporting
Month, impact water quality monitoring at M3 on 18 September 2018 was cancelled
since the access road was blocked by fallen trees after the attack by Super
Typhoon Mangkhut. Therefore, a
total of 12 monitoring
days were carried
out at designated monitoring station M3 for water quality impact monitoring.
The monitoring result of key parameters including Dissolved
Oxygen, Turbidity and
Suspended Solids are summarized in Table 6-1. Detailed monitoring results including
in-situ measurements and laboratory analysis data are shown in Appendix H and graphical

During the Reporting Month, field measurements at M3 showed that temperature of stream water
were within 26.6°C to 30.7°C, the salinity concentrations below 0.1ppt, pH values within 6.5
to 8.5 and the stream flow velocity
between
0.1 and 0.2 m/sec.

6.2.2
Investigation
for the cause of water quality exceedances have been undertaken by ET. Investigation results revealed that water quality
mitigation measures have been implemented to minimize the water quality impact
arising from contract works. Such as temporary bund and de-silting trench were installed
at Retaining Wall RW1 to reduce the suspended solids content in runoff. Series of sheet pile was installed at
site boundary to prevent site runoff flowing to the Conservation Area (CA). Moreover,
exposed surface were covered by tarpaulin sheet as far as practicable. It was observed that
construction of temporary drainage system was on-going and no muddy discharge was observed. Since there
were continuous rainstorms which affecting the water quality of seasonal river course and the pond
of M3 is a catchment of rainwater, it is concluded that the exceedances were related to the impact of rain and unlikely
caused by the works under the Contract 1.
6.2.3
Notifications of Exceedance (NOE) were issued to relevant parties upon confirmation of the monitoring
result. The exceedance
investigation findings are summarized in Table 6-3.

HCTYJV had implemented water quality mitigation
measures and there was no adverse water
quality impact observed during the site inspection.
Having
reviewed the baseline monitoring data at M3, Suspended
Solids of 23.5mg/L was recorded during rainy condition, therefore, the
impact monitoring results of SS are similar to baseline during rainy
condition. It is concluded that the exceedances were related
to the impact of rainstorm and unlikely caused by the
works under the Project.

HCTYJV had implemented water quality mitigation
measures and there was no adverse water
quality impact observed during the site
inspection. Having reviewed the
monitoring data, it is noted that the level of turbidity was gradually
decreased to baseline level after rainstorm happened in early September
2018. Moreover, there was no
exceedance of Suspended Solids (SS).
It is concluded that the exceedances were related
to the impact of rainstorm and unlikely caused by the
works under the Project.
|
6.2.4
Although the exceedances were concluded as not related the works under Contract 1, the
Contractor was reminded to fully implement water quality mitigation measures such as
exposed surface and area with low operation frequency should be covered by
impervious sheeting. Moreover,
temporary drainage and collection system for site runoff should be fully
accomplished as soon as possible which could highly reduce water quality impact to
the surrounding watercourse and ecosystem.
7.1.1
According
to approved EIA report (AEIAR-198/2016), habitat types within project boundary
comprise of watercourse, grassland, upland grassland, plantation, woodland and
developed area. Natural habitats were of moderate ecological value in terms of
species diversity, species rarity, species abundance, ecological linkage as
well as nursery. Moreover, 0.3ha of wet woodland on the northern side of Sandy
Ridge was deemed habitat with high ecological value. Four types of habitats were regarded as
ecologically sensitive habitats, namely wet woodland, watercourses, upland
grassland and woodland. Considering human disturbance in upcoming construction
and operation phases, ecologically sensitive habitats shall be monitored in
accordance with EM&A Manual.
7.1.2
The objective of ecologically
sensitive habitats monitoring is to evaluate the effectiveness of measures to
minimize impacts on concerned habitats from disturbance and pollution. In order
to monitor the effectiveness of the measures to the minimize impact on
ecologically sensitive habitats from disturbance and pollution, monthly
monitoring during construction and operation phases is required as specified in
EM&A Manual. Standard faunal transect and sampling surveys cover both
wetland habitats
(wet woodland and watercourse) and
non-wetland habitats (upland grassland and woodland).
7.2.1
Wetland
habitats include wet woodland and watercourses. Monitoring surveys using
standardized quantitative methodology will conduct at fixed points. For seasonal watercourse, the survey
will be conducted whenever the habitat appears. Measures to respond to
decreases in numbers of aquatic fauna using the wetland habitats and
Action/Limit levels to trigger these measures are detailed in Table
7-1.

The
detailed survey report is attached in Appendix K.
7.3.3
The tentative ecology inspection and monitoring in the next
reporting period (October 2018) is scheduled on 4th October 2018.
8.1.1
The EIA has recommended EM&A for landscape and visual
resources to be undertaken during the design, construction and operational
stages of the project. The design, implementation and maintenance of landscape
mitigation measures is a key aspect of this and should be checked to ensure
that they are fully realized and that potential conflicts between the proposed
landscape measures and any other project works let its are resolved at the
earliest possible date and without compromise to the intention of the
mitigation measures. In addition, implementation of the mitigation measures
recommended by the EIA will be monitored through the site audit programme.
8.1.2
A number of mitigation measures to ameliorate the landscape and
visual impacts of the Project implementation is
summarized in the EMIS of Appendix 13.1 of the EIA Report.
8.1.3
The landscape and visual
mitigation measures proposed should be incorporated in the landscape and
engineering design. Mitigation
measures to be implemented during construction should be adopted from the start
of construction and be in place throughout the entire construction period. Mitigation measures to be implemented
during operation should be integrated into the detailed design and built as
part of the construction works so that they are in place on commissioning of
the Project. Tree transplantation
and compensatory planting should be carried out as early as possible in the
Project with transplantation carried
out prior to construction starting in any particular area.
8.1.4
During
construction phase, Landscape & Visual Monitoring of the contractor’s operations should be conducted monthly and
reported by ET, and countersigned by IEC.

12.3.1
Key
issues to be considered in the coming month for the works of Contract 1 include:
Ÿ Implementation of control measures for
rainstorm;
Ÿ Regular clearance of stagnant water during
wet season;
Ÿ Implementation of dust suppression measures
at all times;
Ÿ Potential wastewater quality impact due to
surface runoff;
Ÿ Potential fugitive dust quality impact due
from the dry/loose/exposure soil surface/dusty material;
Ÿ Ensure dust suppression measures are
implemented properly;
Ÿ Sediment catch-pits and silt removal
facilities should be regularly maintained;
Ÿ Discharge of site effluent to the nearby
wetland is prohibited;
Ÿ Nearby wetland prohibited stockpiling
and/or disposal of materials;
Ÿ Follow-up of improvement on general waste

13.1.1
This
is the 2nd
monthly Environmental Monitoring and Audit Report presenting the
monitoring results and inspection findings for the period of 1 to 30 September 2018.
13.1.2
No
24-hour or 1-hour TSP monitoring result that triggered the Action or Limit
Levels was
recorded. No NOEs or the associated
corrective action was therefore required.
13.1.3
No
noise complaint (which is an Action Level exceedance) was received and no construction
noise measurement result that exceeded the Limit Level was recorded in this Reporting Month. No NOEs or the associated corrective actions
were therefore issued.
13.1.4
For water quality monitoring, a total of 18
Limit Level (LL) exceedances, including 12 LL exceedance of turbidity and 6 LL exceedances of
SS were recorded at designated monitoring location M3. Investigation results revealed that
water quality mitigation measures have been implemented to minimize the
water quality impact arising from contract works. Such as temporary bund and de-silting trench were
installed at Retaining Wall RW1 to reduce the suspended solids content in
runoff. Series of sheet pile was
installed at site boundary to prevent site runoff flowing to the Conservation
Area (CA). Moreover, exposed surface were covered by tarpaulin
sheet as far as practicable. It was
observed that construction of temporary drainage system
was on-going and no muddy
discharge was observed. Since there were continuous rainstorms which affecting the water quality of seasonal river
course and the pond of M3 is a catchment of rainwater, it
is concluded
that the exceedances were related to
the impact of rain and unlikely caused by the works under the
Contract 1.
13.1.5
Monthly ecological
monitoring for
sensitive habitat is undertaken on 11th September 2018. Moreover, Landscape and visual inspection was undertaken by the
RLA on 28th
September 2018.
13.1.6
In the Reporting Period, no environmental complaint, summons and prosecution was received. In addition, no complaints received and emergency events relating to
violation of environmental legislation for illegal dumping and landfilling
were received.
13.1.7
In the Reporting Period, joint site inspections to
evaluate the site environmental performance were carried out by the RE, ET and the Contractor on 6th,
13th, 20th and 27th September 2018 and IEC attended joint site inspection on 13th September 2018. No
non-compliance of environmental issue was recorded.
In general, it was reminded that
water quality mitigation measures should be fully implemented and good housekeeping practice should be
maintained.
13.2.1
The Contractors should pay special
attention on water quality mitigation measures and fully implement according
to the ISEMM of the EM&A Manual, in particular in rainy season to
prevent surface runoff with high SS content and other pollutants from flowing
to local steam and Conservation Area (CA).
13.2.2
Construction
noise would be a key environmental issue during construction phase of the Project. Noise mitigation measures such as using
quiet plants and mobile noise barriers should be implemented in accordance with
the EM&A requirement.
13.2.3
Since
construction site under the Works of Contract 1 of the Project is located near villages, HCTYJV should
fully implement air quality mitigation measures to reduce construction dust
emission.
13.2.4
Furthermore,
daily cleaning and weekly tidiness shall be properly performed and maintained.
In addition, mosquito control should be
performed to prevent mosquito breeding on site.
