According to
findings of the Northwest New Territories (NWNT) Traffic and Infrastructure
Review conducted by the Transport Department, Tuen Mun Road, Ting Kau Bridge, Lantau
Link and North Lantau Highway would be operating beyond capacity after 2016. This forecast has been based on the
estimated increase in cross boundary traffic, developments in the NWNT, and
possible developments in North Lantau, including the Airport developments, the
Lantau Logistics Park (LLP) and the Hong Kong ¡V Zhuhai ¡V Macao Bridge
(HZMB). In order to cope with the
anticipated traffic demand, two new road sections between NWNT and North Lantau
¡V Tuen Mun ¡V Chek Lap Kok Link (TM-CLKL) and Tuen Mun Western Bypass (TMWB) are
proposed.
An
Environmental Impact Assessment (EIA) of TM-CLKL was prepared in accordance
with the EIA Study Brief (No. ESB-175/2007) and the Technical Memorandum of the Environmental
Impact Assessment Process (EIAO-TM). The EIA Report was submitted under the
Environmental Impact Assessment Ordinance (EIAO) in August 2009. Subsequent to the approval of the EIA
Report (EIAO Register Number AEIAR-145/2009), an Environmental Permit
(EP-354/2009) for TM-CLKL was granted by the Director of Environmental
Protection (DEP) on 4 November 2009, and two applications of EP variation,
EP-354/2009/A and EP-354/2009/B, were granted on 8 December 2010 and 28 January
2014, respectively.
Pursuant to Condition
2.6 of the EP, the Detailed Coral Translocation Methodology ([1])
has been submitted on 17 October 2013 and was subsequently approved by
the DEP for this Contract. Coral
translocation was undertaken for the coral colonies at Pillar Point from 21-23
October 2012 prior to commencement of the Northern Landfall on 1 November 2013
in order to reduce the potential marine ecological impacts by translocating movable coral colonies to the receptor site
at Yam Tsai Wan. In accordance with
the Detailed Coral Translocation Methodology, the translocated
coral colonies as well as the tagged natural coral colonies at the receptor
site will be monitored once every three (3) months for a period of 12 months
after the coral translocation exercise.
The purpose of
this Third Quarterly Post-Translocation
Coral Monitoring Report is to report findings of the Third Quarterly Post-translocation
Coral Monitoring which is undertaken at the receptor site, Yam Tsai, Wan, to
monitor the updated status of translocated corals
from the donar site at Pillar Point. The results of the post-translocation
monitoring are reviewed with reference to findings of the pre-translocation
survey in order to assess any observable changes in status of the translocated coral colonies. Post-translocation monitoring results are
also evaluated against Action and Limit Levels which are based on recorded changes
in percentage of partial mortality of the corals.
The remainder
of the report is structured as follows:
Section 2: Third
Quarterly Post-Translocation Coral Monitoring ¡V Details
the methodology and results of the Third Quarterly Post-translocation Coral
Monitoring.
Section 3: Schedule
of Quarterly Post-translocation Coral Monitoring ¡V Details
the tentative schedule of the subsequent Quarterly Post-translocation Coral
Monitoring.
Section 4:
Conclusion ¡V Concludes the Third Post-translocation Coral
Monitoring results for the Contract.
Pre-translocation surveys were undertaken at the donar
site of Pillar Point and receptor site of Yam Tsai Wan to collect baseline data
on translocated coral colonies from Pillar Point and
natural coral colonies at Yam Tsai Wan during the coral translocation exercise
in October 2013. During the
pre-translocation survey, twenty-three (23) colonies of Guaiagorgia sp., twenty-four (24) colonies of Oulastrea crispate and nine (9) colonies of Balanophyllia
sp, which were successfully translocated
from Pillar Point to Yam Tsai Wan, were tagged for monitoring. In addition to the translocated
coral colonies, ten (10) colonies of Guaiagorgia sp., ten (10) colonies of Oulastrea crispata and six (6) colonies of Balanophyllia sp. were tagged at the receptor site.
Each of the tagged coral colonies was identified at least to genus
levels and photographed. The
following data were recorded for each tagged coral colonies during the pre-translocation
survey:
¡P
Genus/ Species;
¡P
Size (Maximum diameter/
height);
¡P
Mortality (%);
¡P
Bleaching (%); and,
¡P
Sediment (%).
During the
Post-translocation Coral Monitoring, the tagged coral colonies were re-visited
for monitoring using the same methodology as the pre-translocation survey. Photographic records of the translocated and natural coral colonies were taken by maintaining
the same aspect and orientation as photographs taken for the pre-translocation
surveys as far as possible. The adoption of the same monitoring method would
allow for direct comparison of baseline pre-location data with the
post-translocation monitoring data in order to determine any changes in
conditions of corals. The
general environmental conditions including weather, sea and tidal conditions of
the coral receptor site were also monitored.
The results of
the post-translocation monitoring were reviewed with reference to findings of
the pre-translocation surveys undertaken at the donar
and receptor sites. If observations
of any die-off / abnormal conditions of the translocated
corals are made during the post-translocation monitoring, the ET should inform
the Contractor, Independent Environmental Checker (IEC) / Environmental Project
Office (ENPO), and AFCD, and liaise with AFCD to investigate any mitigation measures
needed.
Post-translocation Coral Monitoring results were evaluated against
Action and Limit Levels which is based on the recorded changes in the percentage
of partial mortality of the corals (Table
2.1). If the defined Action Level
or Limit Level for coral monitoring is exceeded, the actions set out in Table 2.2 will be implemented.
Table 2.1 Action and Limit Levels
for Post-Translocation Coral Monitoring
Parameter |
Action Level Definition |
Limit Level Definition |
Mortality |
If during Impact Monitoring a 15% increase in the
percentage of partial mortality on the corals occurs at more than 20% of the translocated coral colonies that is not recorded on the
original corals at the receptor site, then the Action Level is exceeded. |
If during Impact Monitoring a 25% increase in the
percentage of partial mortality on the corals occurs at more than 20% of the translocated coral colonies that is not recorded on the
original corals at the receptor site, then the Limit Level is exceeded. |

The Third Quarterly Post-translocation Coral Monitoring was carried out at
the receptor site, Yam Tsai Wan, on 24 July 2014. The weather conditions during the survey
date are summarized in Table 2.3. Location of the survey area at the
receptor site is presented in Figure 2.1.

The species, size, mortality percentage, bleaching percentage and
percentage of sediment cover of the translocated
coral colonies and natural coral colonies recorded during the Third Quarterly
Post-translocation Coral Monitoring surveys are summarized in Tables 2.4 & 2.5. Photographic records taken during the Third
Quarterly Post-translocation Coral Monitoring are shown in Annex A.
Findings of the Third Quarterly Post-translocation Monitoring indicated
that the Action or Limit Levels for coral monitoring were not exceeded as
increase in percentage of partial mortality was not detected for both the
tagged translocated and natural coral colonies when
comparing to the pre-translocation dataset (Tables
2.4 & 2.5). As such, it is
considered not necessary to undertake any action in accordance with the Event
and Action Plan.
Overall, findings of the Third Quarterly Post-translocation Monitoring
did not appear to indicate any deterioration in the general health conditions
of the translocated and natural coral colonies at the
receptor site during this quarterly period.

The Third Quarterly Post-Translocation Coral Monitoring has been carried
out on 24 July 2014 at the receptor site, Yam Tsai Wan, as per the requirements
stipulated in the Detailed Coral
Translocation Methodology.
During the monitoring, 56 translocated coral
colonies and 26 natural coral colonies were re-visited and monitored at the
receptor site, Yam Tsai Wan. The
conditions of the translocated and natural coral
colonies during the Third Quarterly Post-Translocation Coral Monitoring are
compared with the pre-translocation conditions which were recorded during the
coral translocation exercise in October 2013.
Action and Limit Levels for the partial mortality of tagged corals were
established based on the Pre-translocation Coral Monitoring results. By evaluating against the derived Action
and Limit Levels, no exceedances of the Action and Limit Levels were identified
during the Third Quarterly Post-Translocation Coral Monitoring on 24 July
2014. It is thus did not appear to
be any deterioration in the general conditions of the translocated
and natural coral colonies at the receptor site, Yam Tsai Wan.
Overall, the coral translocation exercise is considered to be undertaken
successfully as the translocated corals did not show
any sign of deterioration in condition at the receptor site during this quarterly
survey.
Findings of future Post-Translocation Coral Monitoring survey will be
presented in the subsequent Post-Translocation Coral Monitoring Report in order
to determine any observable changes in status of the translocated
coral colonies. In the event that
deterioration in conditions of the translocated
corals is identified, monitoring would allow for implementation of appropriate
remedial actions to mitigate such changes in condition.
