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 J.
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.

5.6
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
·
Accumulated construction waste was found at area B and broken tree
branches and leaves were found at gully of C66 and on carriageway at TTA32. The
Contractor was reminded to improve housekeeping on site.
·
Oil seepage was observed from a generator and a few oil drums. The
Contractor was reminded to clean up the oil spillage as soon as possible.
·
Water
was observed accumulated in drip trays with generator and oil drums. The
Contractor was reminded to remove them as soon as possible.
·
Oil seepage was observed from a generator set on deck at Grid 6. The
Contractor was reminded to clear the oil stain and dispose of as chemical
waste.
Waste Management
·
Sand was found on carriageway at TTA12 and TTA3. General refuse was
found at F17, deadleaves were found at C545 behind
the temple and untidy condition was found at C143. The Contractor was reminded
to improve housekeeping at the locations.
Water Pollution
·
Blockage of catchpits were found at TTA3, C66
(outfall BB & EE) and C6. The Contractor was reminded to properly maintain
the drainage system to prevent flooding.
·
Deadleaves were found inside u-channel at TTA58-S2. The
Contractor was reminded to properly maintain the drainage system.
·

C6/C66 and gullies at F16 were found blocked. The Contractor was reminded to
properly maintain the drainage system.
·
Deadleaves were found inside u-channel at TTA3. The
Contractor was reminded to properly maintain the drainage system.
Air Emissions
·
Mud trail was found at the site entrance of F17. The Contractor was
reminded to provide wheel-washing at site exits to prevent dust emission.
Noise/Vibration
·
No

observations and recommendations were made during the weekly site inspections
in the month.
Miscellaneous
·
Stagnant water was found at Grid 9 site entrance. The Contractor was
reminded to clear the stagnant water or level the ground to prevent mosquitoes
breeding.
·
Stagnant water was found in the refuse collection bin at Grid 6, inside cachpit at F16 and in the excavated trench at TTA58-S2. The
