5.1
Environmental monitoring of air quality (1-hr TSP and 24-hr
TSP) for the Project was performed in March 2008. There was no
exceedance of 1-hour and 24-hour TSP monitoring recorded in the reporting month.
5.2
Environmental site inspections were conducted 4 times
in the reporting month. Due to the dry weather conditions, minor
fugitive dust was occasionally observed during dumping and manual
sorting at the non-inert stockpile at Area A. The Contractor was reminded to
provide longer water spraying time to the load at the weigh-bridge at Area B1.
The Contractor was also reminded to properly maintain the plants on site to
prevent any dark smoke emission.
5.3
No environmental complaint, non-compliance or prosecutions
or notifications of summons were received in the reporting month.
5.4
According to the environmental site inspections performed in
the reporting month, the following recommendations were provided:
Air Quality
·
Ensure the frequency of water spraying on haul roads,
unloading areas and stockpiles to be sufficient to suppress the dust sources;
·
Provide proper maintenance for the powered mechanical
equipment and barges to avoid emission of dark smoke;
·
Provide water spraying onto the truckloads during inspection
of fill material;
·
Conduct road sweeping on the public
