F.
5.3.2 All the
follow-up actions requested by Contractor’s ET and IEC during the site
inspections were undertaken as reported by the Contractor and confirmed in the
following weekly site inspection conducted during each reporting month.
5.4.1 The
monitoring works conducted by the monitoring team were inspected regularly. The

Air
Quality Monitoring
l Observations
around the monitoring stations were recorded.
l Temperature
and weather conditions on the monitoring days were recorded.
Noise
Monitoring
l Observations
around the monitoring stations were recorded.
l Major noise sources
were identified and recorded. Other intrusive noise attributing to the results
were trimmed off by pausing the monitoring temporarily.
5.5.1 The
Contractor has implemented environmental mitigation measures and requirements
as stated in the EIA Reports, the EP and the EM&A Manuals.
5.5.2 The EM&A
programme was found effective in monitoring the environmental impacts of this
project. Data collection was useful in determining whether the project has caused
unacceptable impacts on the sensitive receivers. The impact monitoring data
indicated whether exceedances would occur and helped determine whether the
works' exceedances were due.
5.6.1
C&D materials and wastes sorting were
carried out on site. Receptacles were available for C&D wastes and general
refuse collection.
5.6.2
The amount of wastes generated by the site
activities in the reporting period is shown in Appendix E.
5.6.3
The Contractor is advised to properly maintain
on site C&D materials and wastes collection, sorting and recording system
and maximize reuse / recycle of C&D materials and wastes. The Contractor is
reminded to properly maintain the site tidiness and dispose of the wastes
accumulated on site regularly and properly.
5.6.4
The Contractor is reminded that chemical waste
containers should be properly treated and stored temporarily in designated
chemical waste storage area on site in accordance with the Code of Practice on
the Packaging, Labelling and Storage of Chemical Wastes.

Cumulative complaint log, summaries of complaints, notification of
summons and successful prosecutions are presented in Appendix G.
5.9.1
The environmental impacts caused by this
project during the construction phase were generally in line with the
predictions in EIA report. Although a few cases of the 24-hr TSP and noise
exceeded the EIA predictions in the reporting period, the inspections showed
all exceedances are considered is not project related.
