Comments on Overall EM&A
Programme
6.3.1 The EM&A programme requires construction phase
monitoring for air quality, construction noise and environmental site audit.
Timely implementation of mitigation measures was carried out according to the
environmental monitoring data obtained during this project.
6.3.2
According
to the email and the completion certification provided by HMJV, the major works
of Contract No. KL/2014/03 has been completed substantially on 31 December
2019. The remaining outstanding construction works are those minor ancillary
works that no Powered Mechanical Equipment (PME) will be involved. No
significant adverse environmental impacts are anticipated in the remaining
construction works. The proposal for Termination of EM&A Programme under
this Contract was certified by the ET Leader, verified by the IEC on 15
December 2020, approved by EPD on 18 March 2021.
6.3.3
The
weekly site inspections were effective to ensure the implementation and
efficiency of the mitigation measures. As a result, an environmental nuisance
to the public could be reduced to a minimum.
6.3.4
Therefore,
the overall performance of the monitoring methodology adopted and environmental
management system in the project was effective.
6.4
Overall EM&A Data
6.4.1
Impact
air quality and construction noise were conducted at the designated monitoring stations
in accordance with the Manual.
6.4.2
The
overall trends of the monitored parameters at the monitoring period were
presented in Appendix D. Due to the construction activity was increasing from
the construction site of Trunk Road T2, an increasing trends of 24hr-TSP
concentration and construction noise level were observed since August 2020.
6.4.3
Total 17
Action Level and 2 Limit Level exceedances for 24-hr TSP were recorded in the
reporting period. Total 3 Limit Level exceedance for construction noise were
recorded in the reporting period. Base on the investigation, the occasional
exceedances were non-project related. In general, the monitoring parameters
were within the range of the baseline levels.
6.4.4
Weekly environmental site inspections were carried
out in the reporting period. Recommendations on mitigation measures for air
quality, noise, water quality, waste management, landscape and visual and
permit / licenses were given to the Contractor for remediating the deficiencies
identified during the site inspections. No non-compliance was found during the
reporting period.
6.5
Conclusions and Recommendations
6.5.1 The recommended environmental mitigation measures,
as proposed in the EIA reports and EM&A Manuals 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.
6.5.2 With the success of the overall EM&A programme,
the deterioration of the environment caused by the Project was cost-effectively
identified and necessary prompt effective mitigation measures were implemented
to avoid any unacceptable impacts. In conclusion, the Project was
environmentally acceptable.
