5.1
Site inspection was carried out on a weekly basis to monitor
the timely implementation of proper environmental pollution control and
mitigation measures for the Project. In the month, four site inspections were
carried out. The summary of weekly environmental site inspections observations
and environmental site inspection checklists are attached in Appendix H.
Review of
Environmental Monitoring Procedures
5.2
The monitoring works conducted by the Environmental Team
were inspected regularly. Observations have been recorded for the monitoring
works as follows:
Air Quality
Monitoring
·
The
monitoring team recorded the observations around the monitoring stations within
and outside of the construction site.
·
The
monitoring team recorded the temperature and general weather condition on the
monitoring day.
Noise Monitoring
·
The
monitoring team recorded the observations around the monitoring stations, which
might affect the results.
·
Major
noise sources were identified and recorded.

During the weekly site inspection conducted by the
Environmental Team in the month, the following observations and recommendations
were made.
Resource Management
·
No
observations and recommendations were made during the weekly site inspections
in the month.
Material
Storage/Spillage/Leakage
·
Oil stain was found under the drip tray for a generator at TTA3. The
Contractor was reminded to clear the oil stain.
Waste Management
·
Small amount of general refuse was observed at Grid 7. The Contractor
was requested to properly collect the general refuse scattered at Grid 7 and
properly maintain the housekeeping on site.
·

2000-2200 and 2400-2600. Leaves were found on carriageway at
Water Pollution
·
Water was leaked from a hose at Grid 7 due to lack of valve control. The
Contractor was requested to install the valve control for the hose to avoid the
wastage of water.
·
Muddy water and leaves were found inside catchpits
