(EM&A) Report presents the EM&A works undertaken in March 2013 in accordance with
EM&A Manual.
10.2 No
Action/Limit Level exceedance was recorded for air
quality, construction
noise
and underwater noise.
10.3 For

for suspended solids were recorded.
10.4 According
to the investigation, no major marine construction activities were conducted
during the monitoring period between 1 and 19 March 2013. No pollution
discharge from the marine works after 19 March 2013 (casing installation works)
were observed. Therefore, all exceedances are
considered not due to the Contract.
10.5 Environmental
site inspection was conducted on 5th,

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
to ensure inert and non-inert C&D materials are properly segregated before
removing off site.
·
To avoid
any discharge or accidental spillage of
chemical waste or oil directly from the site.
·
To avoid
improper handling or storage of oil drum on site.
