Air Quality Impact
¡¤
To
regularly maintain the quality of machinery and vehicles on site.
¡¤
To
implement dust suppression measures on all haul roads, stockpiles, dry surfaces
and excavation works.
¡¤
To provide hoarding along the entire length of that portion of the site boundary.
Noise Impact
¡¤
To
inspect the noise sources inside the site.
¡¤
To space
out noisy equipment and position the equipment as far away as possible from
sensitive receivers.
¡¤
To
provide temporary noise barriers for operations of noisy equipment near the
noise sensitive receivers, if necessary.
Water Impact
¡¤ To prevent any surface runoff discharge into any stream course and sea.
¡¤ To review and implement temporary drainage system.
¡¤ To identify any wastewater discharges from site.
¡¤ To ensure properly maintenance for de-silting facilities.
¡¤ To clear the silt and sediment in the sedimentation tanks.
¡¤ To review the capacity of de-silting facilities for discharge.
¡¤ To divert all the water generated from construction site to de-silting facilities with enough handling capacity before discharge.
¡¤ To avoid accumulation of stagnant and ponding water on site.
Waste/Chemical Management
¡¤
To check
for any accumulation of waste materials or rubbish on site.
¡¤
To ensure the performance of sorting of C&D
materials at source (during generation);
¡¤
To carry out inspection of dump truck at site exit
