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, five 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.
Advice on Waste Management Status
5.3
The actual quantities of uncontaminated sediment,
contaminated sediment, inert C&D materials and C&D wastes generated by
activities of the Project in the month are provided in Table 5.1. Trip ticket
system was implemented for all offsite waste disposal.

in the month.
Material
Storage/Spillage/Leakage
·
One oil drum was found without drip tray on deck at Grid 8. The
Contractor was reminded to provide drip tray to all chemical drums on site.
·
Oil seepage was observed from a drip tray holding an oil drum at Grid 6
(WB) and oil stain was noted underneath a drip tray holding a generator at Grid
6 (EB). The Contractor was requested to clear the seeped oil / oil stain.
·
The Contractor was requested to provide drip tray to an oil drum at Grid
6 (WB).
·
The Contractor was requested to clear the oil left inside the drip tray
at Grid 6 (WB & EB) and handle the cleared oil as chemical waste.
·
Two oil containers were found placed on bareground
without drip tray at Gate 2. The Contractor was reminded to properly store the
chemicals.
