10.1
The Environmental Monitoring and Audit
(EM&A) Report presents the EM&A works undertaken in August 2013 in accordance with
EM&A Manual.
10.2 No
Action/Limit Level exceedance was recorded for air
quality
and construction noise.
10.3 For
water quality monitoring, there
is one Action Level and two Limit Level exceedances
for suspended solids were recorded.
10.4 According to the investigation, no pollution
discharge from the marine works. All exceedances are
considered not due to the Contract as sediment plume due to natural fluctuation
of shallow water was observed and water quality mitigation measures such as
casing and silt curtains were properly implemented.
10.5
Dolphin
transect survey was carried out on 21st and 26th August 2013. No adverse impact on Chinese White Dolphins was noticeable from general observations.
10.6 Environmental
site inspection was conducted on 6th,
13th, 20th and 29th August 2013 by ET in the reporting month. All deficiencies identified during the site
inspection have already rectified / improved during the follow-up audit
session.
10.7 There
was no
environmental complaint, no notification
of summons and successful prosecution received.
10.8 The
ET will keep track on the EM&A programme to
ensure compliance of environmental requirements and the proper implementation
of all necessary mitigation measures.
10.9 According
to the environmental audit performed in the reporting month, the following recommendations were made:
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.
Ecology Impact
¡¤
To
implement Spill Response
Plan in the event of accidental spillage
of or other hazardous chemicals.
¡¤
To
implement Dolphin Exclusion Zone during the installation of bored pile casing located in the waters
to the west of Airport.
¡¤
To
implement Dolphin Watching
Plan after the bored piling casing is
installed.
¡¤
To
ensure the acoustically-decoupled measures were implemented for air compressors
and other noisy equipment mounted on construction vessels according to acoustic
decoupling measures plan.
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.
