5.1
Environmental monitoring of air quality (1-hr TSP and 24-hr
TSP) for the Project was performed in May 2007. There was one limit level
exceedance of 24-hour TSP recorded in the reporting month. The exceedance was
considered partially due to the Project.
5.2
Environmental site inspections were conducted 5
times in the reporting month. Due to the occasional dry weather condition,
fugitive dust was occasionally observed during sorting and dumping activities
at the non-inert waste stockpile in Area A. Mud was occasionally observed
deposited along the haul road due to the raining events in the reporting moth.
5.3
No environmental complaint, prosecutions or notifications of
summons were received in May 2007.
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
road and the main haul roads outside and near the site egress by the road

Undertake water spraying on
stockpiling area by water bowers;
·
Erect adequate speed limit signs to
advise the truck drivers of the speed limit;
·
Operate mist spraying systems and automatic water sprinklers
in the temporary CWSF;
·
Implement
the dust mitigation measures for the construction activities;
·
Designate proper haul roads to ensure effective water
spraying; and
·
Ensure all vehicles to be washed before leaving the site
egress by provision, operation and maintenance of automatic wheel washing
facilities.
Construction Noise
·

channels;
·
Operate and maintain the treatment system for the site
toilet; and
·
Remove the stagnant water or provide pesticide for the

chemical containers, chemical waste storage drums and diesel operated generator
set;
·
Maintain good housekeeping at the workshop area;
·
Ensure sufficient tarpaulin sheets are provided to cover
drip trays;
·
Avoid soil being polluted during oil filling and equipment
maintenance; hence, properly remove and store the contaminated soil, if any,
and
·
Provide a proper chemical waste store.
