Breach of Action and Limit
(A/L) Levels
ES.03.
In the Reporting Month, no
exceedances of air quality and noise
monitoring were recorded. For water
quality, there were two (2) Limit level exceedances recorded at Location M2. Investigation
for the cause of water quality exceedances was undertaken ET which revealed that the Contractor had implemented
water quality mitigation measures and the exceedances were likely related to
the rainstorm not caused by the works under the
Project. The statistics of environmental exceedance,
NOE issued and investigation of exceedance are summarized in the following
table.

ES.010. The Contractors were further reminded to pay special attention on water quality mitigation measures and should fully implement according to the ISEMM of the EM&A Manual, in particular to prevent
surface runoff with high SS content and other pollutants from flowing to local
stream and Conservation Area (CA).
ES.011.
Moreover,
air quality and construction noise are the major environmental issues as under
the Project Works. Air quality mitigation measures such as wheel
wash facilities, watering of haul roads and covering of dusty materials with
tarpaulin sheet should be implemented as far as practicable. Construction noise
mitigation measures such as use of movable noise barriers and Quality Powered
Mechanical Equipment (QPME) should be properly provided to
reduce construction noise impact.
ES.012.
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.

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 ¡V 20 mg/L and 0 ¡V 200% saturation; and
• A temperature of 0 ¡V 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¡V1000 NTU (for example, Hach model 2100Q or an
approved similar instrument).

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¢XC 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
laboratory suspended solids determination. The SS determination work should start
within 24 hours after collection of the water samples. The SS analyses should
follow the APHA Standard Methods 2540D
with Limit of Reporting of 2 mg/L.

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 ¡Ó0.5dB. 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.
5.1.4
In the Reporting Period, there was rainy day on 3
and 14 June 2019. ET had paid
special attention on the weather condition and the noise monitoring was avoided
to be carried under heavy rain during the morning period.
5.2.1
As
shown in Tables 5-1 and
5-2, 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.
6.1.1
Water quality impact monitoring schedule was submitted to all relevant
parties which shown in Appendix G.
6.1.2
In the Reporting Month,
a total of 12 monitoring days were
carried
out for
water quality impact monitoring. The
monitoring result
of key parameters including Dissolved Oxygen, Turbidity and Suspended Solids are summarized in Tables 6-1 and 6-2. Detailed monitoring
results including in-situ measurements and laboratory analysis data are shown
in Appendix H and graphical plots for monitoring result are shown in Appendix

6.2.2
Investigation for the cause of water quality exceedances have been
undertaken by ET. Investigation results revealed that under
the impact of rainstorm, the water quality of the water course was highly
affected by the stirred up sediment and runoff from the surrounding
environment. It is considered that the exceedance was related to the rainstorm
and unlikely caused by the works under the Project. Since the exceedances were
concluded as not project-related, increase of monitoring frequency is not
required according to EM&A Manual 7.8.1.3.
6.2.3
Notifications of Exceedance (NOE) were issued to
relevant parties upon confirmation of the monitoring result. The investigation of exceedance is summarized in Table 6-5.

Turbidity and SS |
There was rainstorm in Northern
District in the morning of 28 June 2019. Under the impact of rainstorm, the
water quality of the watercourse was highly affected by the stirred up
sediment and runoff from the surrounding environment. According to the
baseline data, elevated turbidity
and SS values were recorded at M2 during and after the
event of
rainstorm. In
our investigation, the
Contractor had implemented it is concluded that the water quality mitigation
measure and concluded
that the exceedances were related to the rainstorm and unlikely
caused by the works under the Project. |
6.2.4
Although the exceedances were concluded not related
the works under Contract 2, 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.
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.

7.4.10
The tentative ecology inspection and monitoring in the next Reporting
Month (July 2019) is scheduled on 9th July 2019.
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.

12.3.2
During rainy season, 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 to prevent surface
runoff with high SS content and other pollutants from flowing to local stream and
Conservation Area (CA). The implementation of water quality mitigation
measures conducted by the Contractors is shown in Appendix O.
13.1.1
This
is the 11th Monthly Environmental Monitoring and Audit
Report presenting the monitoring results and inspection findings for the period of 1 to 30 June
2019.
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, 2 LL exceedances, including 1 exceedance of turbidity and 1 exceedance of
SS were recorded at Location M2. In our investigation, there
was rainstorm in Northern District on the exceedance
days. According
to the baseline data, elevated turbidity and SS values were recorded at M2 during and after the event of
rainstorm. In our investigation, the Contractor had implemented it is concluded
that the water quality mitigation measure and concluded
that the exceedance was related to the rainstorm and unlikely caused by the
works under the Project.
13.1.5
Monthly ecological
monitoring for
sensitive habitat for area of Contract 1 and Contract 2 were undertaken on 20th
June 2019. Moreover, Landscape and visual inspection at both Contracts were undertaken by the RLA on 20th June
