8. CONCLUSION AND RECOMMENDATION
8.1 Conclusions
8.1.1 No Action and Limit
Level exceedance was recorded for air quality monitoring and construction noise
monitoring in the reporting period.
8.1.2 No Action Level
exceedance but three (3) Limit Level exceedances were recorded for water
quality in the reporting period. It was found that these exceedances were not project-related.
8.1.3 No Action / Limit
exceedance was recorded for noise levels at stations (NMS1 and NMS2) in close proximity to the active ardeid night roosts in the
monitoring period.
8.1.4 A total of two (2)
Action Level exceedances were recorded for the ecological monitoring of birds
during the reporting period. However, these exceedances were not project-related.
8.1.5 13 environmental site
inspections and 13 landscape and visual site audits were carried out in the
reporting period. Recommendations on mitigation measures were given to the Contractor for
remediating the deficiencies identified during the site inspections.
8.1.6 Referring to the
Contractor’s information, no environmental complaint, notification of summons
and successful prosecution was received in the reporting period.
8.1.7 The EM&A
methodology has been effective in monitoring the environmental impacts of the
Project and the effectiveness of the mitigation measures. The data collected
were useful in determining whether the Project had caused unacceptable impacts
on the sensitive receivers. Analysis of all EM&A data collected throughout
the baseline and the impact periods demonstrated the environmental
acceptability of the Project.
8.2 Comment
and Recommendations
8.2.1 The recommended
environmental mitigation measures, as proposed in the EIA report and EM&A
Manual shall be effectively implemented to minimize the potential environmental
impacts from the Project. The EM&A programme would effectively monitor the
environmental impacts generated from the construction activities and ensure the
proper implementation of mitigation measures.
8.2.2 According to the
environmental site inspections performed in the reporting period, the following
recommendations were provided:
Air Quality Impact
·
Stockpiling of excavated soil should be covered with impermeable
sheeting and contained properly to prevent contaminated runoff and dust
emission at main store area where SI works of SCAP is conducting.
·
The contractor is reminded to cover the stockpiling of excavated soil
with impermeable sheeting to prevent ingress of water during rainstorms and/ or
prevent dust emission near the demolished PST.
·
The Contractor is recommended to increase watering for dust suppression
during demolition of workshop.
·
The Contractor is reminded to cover the excavated soil properly with
tarpaulin sheets to prevent dust emission for trial pit.
·
Wind blown dust is observed
when the truck is leaving at site exit. The Contractor should provide
mitigation measures to prevent dust emission from vehicle wheel & body.
·
The Contractor is required to improve the mitigation at present wheel
wash area at southern exit (e.g. provide better bedding of aggregates for
preventing muddy water).
Construction Noise Impact
·
No specific observation was identified in the reporting period.
Water Quality Impact
·
The contractor is reminded to provide mitigation measure to prevent
silty runoff getting into the storm drain near main store area.
·
Mitigation measure should be provided to prevent direct discharge of
runoff at Zone 1 area near detritor.
·
The contractor is reminded to de-silt the gullies near the main entrance
to the piling area.
·
Provide mitigation to prevent direct discharge of silt-laden water into
the storm drain near the boot cleaning basin.
·
The Contractor is reminded to provide MSDS information at WetSep.
·
Mitigation measures should be provided to intercept silty runoff from
the piling area.
Chemical and Waste Management
·
Stockpiling of excavated soil should be covered with impermeable
sheeting and contained properly to prevent contaminated runoff and dust
emission at main store area where SI works of SCAP is conducting.
·
The contractor is reminded to cover the stockpiling of excavated soil
with impermeable sheeting to prevent ingress of water during rainstorms and/ or
prevent dust emission near the demolished PST.
·
Drip tray should be provided for the chemical as mitigation to prevent
accidental spillage.
·
The Contractor is reminded to provide drip tray for the chemicals to
prevent accidental spillage.
·
The Contractor is reminded to cover the excavated soil properly with
tarpaulin sheets to prevent dust emission.
Land Contamination
·
No specific observation was identified in the reporting period.
Ecological Impact
·
The contractor is reminded to maintain and reinstate the bird curtain at
the northern site boundary.
·
The contractor is reminded to maintain and reinstate the silentup at the northern site boundary.
Landscape and Visual Impact
·
The contractor is reminded to closely monitor the three condition of
Tree T028 for open cut too close to the tree near temporary administration
building.
Hazard to Life
·
No specific observation was identified in the reporting period.
Permit/ Licenses
No specific observation was identified in the reporting period.
