10.1
The Environmental Monitoring
and Audit (EM&A) Report presents the EM&A works undertaken in October 2014 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 are twelve Action Level and ten
Limit Level exceedances for suspended solids were recorded. In addition, no Action/Limit
Level exceedance for dissolved oxygen and turbidity were recorded.
10.4
According to the investigation, the exceedances are considered not due
to the Contract due to the following reasons:
1)
No pollution discharge was observed from the site;
2)
Sediment plume due to natural fluctuation of shallow water and movement
of vessel;
3)
Sediment plume discharging to the monitoring stations from the area
outside the site boundary;
4)
No marine construction works were conducted in vicinity of monitoring
station in which exceedance was recorded; and
5)
The exceeded results were similar or within the ranges baseline
monitoring results.
10.5
Dolphin
transect survey was carried out on 8th and 22th October 2014. No adverse impact on Chinese White Dolphins was noticeable from general
observations.
10.6
Two days of additional Land-based Dolphin
Behaviour and Movement Monitoring were conducted on 20th and 27th October 2014.
10.7
Environmental site inspection was
conducted on 7th, 14th, 21st and 31st October
2014 by ET in the reporting month. All deficiencies identified during the site inspection have already
rectified / improved during the follow-up audit session.
10.8
No inspection to the Sha Lo Wan (West) Archaeological
Site was conducted in the reporting month.
10.9
There were no environmental
complaint, one notification of summons and successful prosecution
received.
10.10 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.
10.11 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.
