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).
Salinity Measurement
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.

According to the Contractor¡¦s work programme, there were no construction activities carried out adjacent to locations M1 and M2. The entire Sandy Ridge project was partially commenced at western side of Sandy Ridge and Lin Ma Hang Road, in view of the geographical area of Contract 2, there would be no possible discharge to the monitored channel. According to the weather information from the HKO, there was heavy rainstorm on 15 and 17 September 2020, in which Amber Rainstorm Signal was issued in the afternoon on 15 September 2020. Under the impact of rainstorm, the water quality of the watercourse was deteriorated by the stirred up sediment and runoff from the surrounding environment. Based on the above investigation, it was concluded that the exceedances were related to the impact from rainstorm and not caused by the works under the project. |

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.

7.5.2
In the Reporting period,
there was no precautionary check for the presence of nesting
birds carried out for Contract 1
and Contract 2 outside the breeding season.
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.

13.1.1 This is the 26th Monthly EM&A Report presenting the
monitoring results and inspection findings for the period of 1st to 30th September 2020.
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 2 Action Level and 8 Limit Level exceedances
were recorded In the Reporting Period.
NOE were issued to relevant parties and the investigation has been
conducted by ET. Investigation revealed that the Contractor had implemented

rainstorm and not caused by the work under the project.
13.1.5 Monthly ecological monitoring for sensitive habitat for area of
Contract 1 and Contract 2 were undertaken on 3rd September 2020. No significant reduction
in taxa diversity and abundance was observed
in the both surveys. Furthermore, as
advised by both Contractors, there were no vegetation clearance conducted within
the site in the Reporting Month and therefore precautionary check for the presence
of nesting birds was not required.
13.1.6 Landscape and
visual inspection at
both Contracts were undertaken by the RLA on 24th
September 2020. The Contractor was reminded to prevent the
construction material pile within TPZ and ensure no works is allowed within the
TPZ.
13.1.7
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.
13.1.8 No notification of summons or prosecution were
received and recorded for the project.
13.1.9 In the Reporting Month, joint site inspections for
Contract 1 to evaluate the site
environmental performance were carried out by the RE, ET and the Contractor on 3rd,
10th, 17th, 24th and 30th September 2020 and IEC attended joint site inspection on 17th September 2020. No non-compliance
was noted.

13.2.1
The Contractors are reminded to pay special
attention on water quality mitigation measures and should fully implement the
measures as recommended in the EM&A Manual, in particular to prevent
surface runoff and other pollutants from flowing to local stream and
Conservation Area.
13.2.2
Since dry season is approaching, air
quality mitigation measures such as wheel wash facilities, watering of haul roads,
loose soil construction surface and covering of dusty materials with tarpaulin
sheet should be implemented as far as practicable.
13.2.3 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.
13.2.4 Since some of the construction site under the Project is
located near villages, both
Contractors should fully implement air quality mitigation
measures to reduce construction dust emission.
13.2.5 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.
