10.1
The Environmental Monitoring and Audit
(EM&A) Report presents the EM&A works undertaken in June 2016 in accordance with
EM&A Manual.
10.2
No
Action/Limit Level exceedance was recorded for air quality and construction
noise.
10.3
There are three Action Level and no Limit Level
exceedances were recorded for dissolved oxygen (bottom depth). No Action/Limit
Level exceedance for dissolved oxygen (surface and middle depth), turbidity and
suspended solids were recorded. According to the investigation, no pollution
discharge was observed from the site. In addition, control Station
value already exceeded either the Baseline Action or Limit Levels. Therefore, the
exceedances are considered not due to the Contract.
10.4
Dolphin
transect survey was carried out on 8th and 20th June 2016. No adverse impact on Chinese White Dolphins was noticeable from general observations.
10.5
Two
days of additional Land-based Dolphin Behaviour and Movement Monitoring were conducted on 2nd and 16th
June 2016.
10.6 Environmental
site inspection was conducted on 7th, 14th, 21st
and 28th June
2016 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 The
inspection to the Sha Lo Wan (West) Archaeological Site was conducted on 28th
June 2016. No access to Sha Lo Wan (West) Archaeological site for works areas
and storage of construction equipment was observed.
10.8 There
was no environmental
complaint, no notification
of summons and successful prosecution received in the reporting month.
10.9 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.
10.10 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.
