Monthly ecological monitoring for sensitive
habitat in both
wetland and non-wetland for area of Contract 1 and Contract 2 were undertaken areas on 3rd
September 2020. In the Reporting
Month, there was no precautionary check for the presence of nesting birds carried out for Contract 1
and Contract 2 outside the breeding season.

Landscape and visual inspection at
both Contracts were undertaken on 24th
September 2020. The Contractor was reminded
to prevent the construction material pile within Tree Protection Zone and
ensure no works is allowed within the TPZ.
ENVIRONMENTAL COMPLAINT
ES.06.
In the Reporting Month, one
(1) environmental
complaint was received from EPD regarding suspected illegal discharge from a
CEDD's construction site at the upstream leading to the accumulation of silting
at DSD's drainage channel at the downstream Nam Hang Stream. In our investigation, there
was no evident of muddy/ turbid discharge from the construction site and water
quality mitigation measures implemented in Contract 2 was general in order and
no deficiency of water quality impact was observed during weekly site
inspection. It is considered that
the complaint was not valid to the Contract. However, the Contractor was reminded to
fully follow the mitigation measures as recommended in the EM&A Manual as
far as practicable to minimize the impact and nuisance to the public. The statistics of environmental complaint
are summarized in the following table.

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 ¡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).

3.5.16
A portable salinometer capable of measuring
salinity in the range of 0¡V40 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¢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.
