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 and Limit
Level exceedance was recorded for water quality in the reporting period.
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
No Action / Limit
exceedance was noted for the ecological monitoring of birds during the
reporting period.
8.1.5
12 environmental
site inspections and 12 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
No environmental
complaint, notification of summons and successful prosecution was recorded 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 monitoring 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
·
The Contractor is reminded to increase watering for dust suppression
during the demolition of sediment tank.
Construction Noise Impact
·
No specific observation was identified in the reporting period.
Water Quality Impact
·

·
Mitigation measure should be provided to prevent direct discharge of
runoff near the main entrance.
·
The Contractor is reminded to de-silt the gullies near the main entrance.
·
