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.
