7 FUTURE
KEY ISSUES
Key Issues
in the Coming Three Months
7.1 The major
construction activities undertaken in the coming three months will include:
l Open cut
excavation
l Removal of
soil
l Construction
of footings
l Construction
of pile cap
l Mock up construction
l U.U. Lead
in and Pipe Duct Connection
7.2 Potential
environmental impacts arising from the above construction activities are mainly
associated with construction dust, noise, water quality, waste management and
ecology. The proactive Environmental Protection Proforma summarizing the major
site activities, potential environmental impacts and recommended mitigation
measures for the coming months could refer to relevant Monthly EM&A Report.
7.3 Dust
can be generated during construction works and exposed site area in the summer
months and windy weather in the upcoming dry season. To prevent high dust
concentrations during the summer months, the Contractor should pay attention on
the air quality mitigation measures as far as practicable to minimise the dust
impact to the villages which are located adjacent to the Project works. The
Contractor was also reminded to follow the Project Implementation Schedule in
approved EIA report / EM&A Manual to implement appropriate dust control to
reduce dust emissions from heavy construction activities (including ground
excavation, earth moving, etc.) at all active works area exposed site surfaces
and unpaved roads, particularly during dry weather and covering 80% of
stockpiling area by impervious sheets and spraying all dusty material with
water immediately prior to any loading transfer operations to keep the dusty
materials wet during material handling at the stockpile areas as well as the
relevant dust control practices as stipulated in the Air Pollution Control
(Construction Dust) Regulation so that no adverse dust impact arising from the
Project works site.
7.4 In
addition, construction noise is also one of the key environmental issues during
construction of the Project. Noise mitigation measures such as using quiet
plants and noise barriers should be in place, where applicable. In addition,
the Contractor was reminded to frequently check and maintain the acoustic
materials wrapped on noisy part of PME and ensure no gaps between noise
barriers; proactively identify any potential construction noise impact to NSRs
and provide sufficient mitigation measures if necessary; and provide
notification to nearby villagers in Kong Nga Po for potential noisy works at
works area.
7.5 All
other mitigation measures recommended in the Project Implementation Schedule in
approved EIA report / EM&A Manual should be properly implemented and
maintained as far as practicable.

environmental non-compliance was recorded.
Environmental
Complaint and Successful Prosecution
8.6 One complaint
related to water quality was received in the reporting month. No complaints
related to air quality. No notification
of summons or successful prosecutions was received in the reporting quarter.
Recommendations
8.7 The
mitigation measures recommended in the EIA report and EM&A Manual are
considered effective and efficient in minimizing environmental impacts due to
construction of the project during the reporting quarter. The EM&A
programme implemented by the ET has effectively monitored the environmental
impacts arising from the construction activities and ensure the proper
implementation of mitigation measures.
8.8 The
effectiveness and efficiency of the EM&A programme will be continuously
reviewed. The EM&A programme will be improved if deficiencies of the
existing EM&A programme are identified.
8.9 According
to the environmental audits performed in the reporting quarter, the following
recommendations were provided to remediate any potential impacts due to the
Project:
Air
Quality Impact
l To
maintain the cover for stockpile of dusty materials and exposed slope for dust
suppression;
l To enhance
the dust suppression measures including watering for the dust generation works,
exposed site area and haul road;
l To regular
check the valid NRMM labels are properly displayed on the regulated machines
and non-road vehicles; and
l To
maintain the wheel washing facilities provided at every construction site exit
where practicable are functioning properly.
Construction
Noise Impact
l To keep
inspect the noise sources inside the site;
l To keep
space out noisy equipment and position the equipment as far away as possible from
sensitive receivers; and
l To
maintain temporary noise barriers for operations of noisy equipment near the
noise sensitive receivers, if necessary.
Water
Impact
l To
maintain the cover for open stockpile of and exposed slope;
l To keep
reviewing and updating temporary drainage system;
l To
maintain the earth bunds or sand bag barriers on site to direct stormwater to
silt removal facilities;
l To
maintain and ensure the silt removal facilities are functioning properly;
l To
maintain the wheel washing facilities provided at every construction site exit
where practicable are functioning properly; and
l To divert
the muddy water at the retention pond to the wetsep for treatment before
discharging out.
Waste/Chemical
Management
l To check
for any accumulation of waste materials or rubbish on site;
l To avoid
any discharge or accidental spillage of chemical waste or oil directly from the
site;
l To
maintain the drip tray well to prevent oil and chemical leakage; and
l To avoid
improper handling, storage and dispose of oil drums or chemical containers on
site.
Ecology
l To erect
and maintain the protection fence around the retained trees / conservation
species;
l To keep
the tree protection zone large enough to protect the tress; and
l To remove
the construction materials within the tree protection zone.
Landscape and Visual
l To erect
and maintain the protection fencing and tree protection zone around the
preserved trees;
l To remove
the construction materials within the tree protection zone; and
l To keep
the tree protection zone large enough to protect the tress.
