The construction works for PAFF commenced in November
2005 based upon the previous EIA (EIAO
Register Number AEIAR-062-2002) conducted and the Environmental Permit EP-139/2002 granted on the 28th
August 2002. Due to minor changes to the
detailed layout of the site and the site boundary, application for Variation to
the Environmental Permit (VEP) (VEP-133/2004)
was submitted to the Director of Environmental Protection (DEP) for
approval. The variation to the EP (EP-139/2002/A) was granted by the EPD in
February 2004.
However, the
decision by the EPD to grant the above Environmental Permit was subject to a
Judicial Review. The Judicial Review
sided in the favour of the DEP, as did the subsequent Judgement from the Court
of Appeal from the High Court for Judicial Review in March 2005. However, the DEP’s decision to grant the EP
was quashed by the Judgement of the Court of Final Appeal of July 2006.
The construction
works were stopped following the Judgement of the Court of Final Appeal of July
2006. As such, in order to continue with
the construction of the project, the project went through the statutory
procedures under the EIAO again with a new design in order to obtain an
environmental permit. The revised EIA
was submitted in 2007 and the environmental permit (EP-262/2007) was granted in May 2007. EP-262/2007
has been amended to EP262/2007/A and
issued by the EPD on 30 November 2007.
The construction works and EM&A requirements were
resumed on 9th July 2007 following the latest requirements of the EP-262/2007 and EM&A Manual. Details
regarding the EM&A requirements and changes should refer to the updated EM&A Manual. For the marine works, all piling activities
were completed before the previous suspension of construction works in 2006.
This is the fourteenth
EM&A Report which summarizes the monitoring results and audit findings for
the EM&A programme during the reporting period from 1st December to 31st
December 2007.
The project area
is in Area 38 of Tuen Mun and the pipelines are located in
No air and noise
sensitive receivers were identified close to the project area. However, water sensitive receivers and ecological
sensitive receivers were identified in the EIA study, and are shown in Annex B.
A summary of the major
works undertaken in this reporting period is shown in Table 2.1.

According to the EP requirements, a Community Liaison
Group (CLG) shall be established within three months after commencement of
construction of the Project. The major
duty of CLG is to advise on and monitor the proper design, construction and
operation of the Project. The CLG
comprises representatives from Airport Authority, members of Tuen Mun community
and academics. During the reporting
month, the CLG held a meeting cum site visit on 7 December 2007.
The details of PAFF CLG
(including Membership and its Terms of Reference) and the meeting minutes can be
found on the Project website (http://www.paffhk.com).
Water quality monitoring during dredging activities recorded daily
exceedance of Action Levels of Depth-averaged Turbidity. There was exceedance of the Action Levels of
Depth-averaged Suspended Solids (SS) on the 21, 24, 25, 27, 29 and 30 December,
and exceedance of the SS Limit Levels on the 27, 29 and 30 December. A description of the actions taken following
these non-compliances is discussed in Section
3.2.
No environmental complaints were received during the reporting
period. A summary of environmental
complaints since project commencement is presented in Annex D.
No summons were
received in this reporting period. A
summary of legal proceeding since project commencement is presented in Annex D.
As no environmental
complaint was received over the last reporting period, no follow-up action was
required.
Weekly site
inspections were carried out by the ET on 5, 13, 17, and 28 December 2007. Overall, the site was in good orderly manner and
no non-compliance was found.
Environmental deficiencies and follow-up actions/mitigation measures
were identified during the inspections, as follows:
Air Quality
·
Water tankers
were used regularly to wet the road surface to minimize dust emission.
·
Site entrance was
paved and wheel-washing facility was provided to avoid dust deposit on the
public road.
·
Main access road
within the site (between site office and exit) was paved to avoid dust
emission. Other sections of the major
access road in the construction area were paved with stones.
Noise
·
No noisy
activities were conducted during the audit.
·
All air
compressors on site were operated with a valid noise label.
Water Quality
·
Site toilets were
provided on site. A soil soakaway system
with holding tanks was installed to treat the sewage from the toilets. No effluent discharge out of the site was
made.
·
The site canteen
is no longer in operation and hence no waste water is generated.
Waste Management
·
During the site inspection on 28 December
2007, water ponding was found near site entrance. The Contractor was recommended to clear the
ponding.
·
During the site inspection on 17 and 28
December 2007, stockpiles of excavated materials were found near the site
entrance. The Contractor was recommended
to cover excavated materials with tarpaulin to avoid fugitive dust
generation.
Landscape and Visual
·
The transplanted trees at the new site were
in good and healthy condition; and,
·
The berm was habilitated by vegetation.
Overall, the site
was in a good orderly manner. 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.
Water quality monitoring
during dredging activities recorded daily exceedance of Action Levels of
Depth-averaged Turbidity. There was
exceedance of the Action Levels of Depth-averaged Suspended Solids (SS) on the
21, 24, 25, 27, 29 and 30 December, and exceedance of the SS Limit Levels on
the 27, 29 and 30 December. There was
both mid-ebb and mid-flood exceedance for SS on the 24, 25 and 30 of
December. Details of exceedance were
presented in the monitoring results Annex G. A description of the actions taken followng
identification of a non-compliance are discussed in Section 3.
Although dredging
operations were undertaken during the reporting period, the exceedances were
unlikely to be caused by the Project and were considered to be an isolated case
due to the following reasons:
·
Exceedance
of Action Level of depth-averaged Turbidity was found on 17, 21, 22, 31
December (when no dredging was undertaken), whose values were comparable to
those of days with dredging operations
·
Depth-averaged
DO, bottom DO and depth-averaged SS did not show the same trend of exceedance
As per the
requirements of the EM&A Manual, incidents were notified to the
Franchisee’s Site Representative, the Contractor and the Independent
Environmental Checker upon identification of an exceedance.
The temporal and
spatial trend of the results collected during the impact monitoring have
been plotted against those collected during the baseline monitoring and are
discussed below. Results are illustrated
in Figure
G3 in Annex G.
During impact
monitoring on the ebb tide, turbidity and SS levels at all stations, with the
exception of Impact Station MP, are generally comparable with those levels
recorded during the baseline monitoring.
It is noted that there appears to be an increasing trend in both
turbidity and SS levels at Station MP between 22 and 30 December (maximum of
40.2 NTU and 37.2 mg/L respectively), however, as this station was located over
1.5 km upstream from the dredging operation, it is considered unlikely that
these levels are attributable to Project works.
It is more likely that the waters upstream of the works site are
influenced by other factors, such as natural fluctuations of turbidity and SS
observed in the Pearl River Estuary.
During impact
monitoring on the flood tide, both turbidity and SS levels at all stations, are
generally comparable with those recorded during the baseline monitoring. An exception was noted for 27 December where
maximum levels were higher than those recorded during other monitoring
events. As levels returned to levels
comparable with other monitoring events the following day, such fluctuations
are not considered to be of a concern.
It is also
important to note that the construction works were not carried out continuously
over the weeks during the impact monitoring period. On some occasions, there were no marine works
undertaken on site during the monitoring period.
Whilst it is
noted that there were no apparent spatial trends in the monitoring data, there
does appear to be an overall temporal increase in concentrations of monitoring
parameters. As this increase is noted to
be generally consistent over all monitoring stations, it is considered that
this change is likely to be reflective of natural conditions. Nevertheless, such patterns will be examined
over the remaining monitoring period to verify whether the trend continues.
In accordance with
the required procedures specified in the EM&A Manual to be taken following
the trigger of an Action Level, discussions between the Environmental Team and
the Independent Environmental Checker (IEC) have resulted in a recommendation
of an amendment to be made to the Action Level for the monitoring of Turbidity
for the Project.
It is noted that
for Dissolved Oxygen (DO) and Suspended Solids (SS) a set Action and Limit
Levels have been established taking into consideration both the baseline data
as well as the Environmental Protection Departments (EPD) routine water quality
monitoring data collected between 1998 and 2006. This value thus takes into account historical
fluctuations in ambient conditions and thereby could be considered to be more
representative of natural change.
Presently, monitoring for Turbidity does not take into account natural
spatial and temporal patterns, but is rather restricted to Action Levels that are
determined by the water quality data collected at upstream control station on
the day of monitoring. It is therefore
recommended that the Action Level of Turbidity be amended to follow the same
principle as that currently applied to DO and SS.
Steps to
potentially amend the Action Level of Turbidity are currently in discussion
with the IEC and the EPD and will be presented in the revised Baseline Water Quality Monitoring Report. The progress of these recommendations will be
document in the next Monthly Monitoring
Report.
The
implementation status of environmental mitigation measures and requirements as
stated in the EIA Report, Environmental Permits and EM&A Manual during the
reporting period is summarized in Annex
E.
Air and Noise
monitoring is not required for the project.
In accordance to
the EM&A Manual, during dredging activities, water quality monitoring
commenced on 17 December 2007. QA/QC reports for Suspended Solids testing are
presented in Annex F. Monitoring data and graphical
presentations of the results are included in Annex G.
Results of the
monitoring demonstrated that all measured dissolved oxygen levels of all Impact
Stations were compliant with the Action and Limit (AL) Levels specified in the
EM&A Manual. Concentrations of
Suspended Solids (SS) were generally below AL Levels, however, exceedances were
noted for 21, 24, 25, 27, 29, 30 December 2007.
Turbidity levels were, however, above Action Levels on a daily basis
during the reporting month. A review of
the above exceedances concluded that these were not attributable to Project
works and were likely due to natural variation (see Section 3.2 for further details).
At the time of this report, laboratory analysis of POPs was still in progress. Results of POPs monitoring will be presented
in the next Monthly Monitoring Report once
they become available.
Since dredging activity
has not reached the sediment removal of 3km (for SS) and 2km (SS2) level during
the reporting period, marine archaeological monitoring was not required.
According to the
EIA report and EM&A Manual, mitigation measures and site inspection are
required during the landscaping/planting works.
The berm/landscaping bund was habilitated by vegetation which was grown
during the project suspension period.
The transplanted trees were in good and healthy condition.
The weekly site
inspections included audits on landscape and visual issues to ensure that the
site was in orderly acceptable manner.
According to the
EIA report and EM&A Manual, mitigation measures and design phase audit are
required to minimise the risk of fuel spill and hazards. The Contractor will
submit the updated design audit plan according to the EP requirements.
Pursuant to Condition 3.5 of the EP, the Contractor
submitted three design drawings which address the specific sub-clauses on Condition 3.5a of the EP concerning the
containment systems of aviation fuel storage tank farm. The ET and the IEC have provided
certification and verification to the drawings respectively and the drawings
were submitted to the EPD on 7 November 2007.
Weekly site
inspection covered the waste management aspects which included measures to
prevent land contamination by chemical wastes.
In accordance to
EM&A Manual, dolphin monitoring has been undertaken during dredging
activities since 17 December 2007.
During the
reporting period, two dolphin sightings were recorded outside the exclusion
zone on 25 December and 28 December, with only one dolphin sighting recorded
within the exclusion zone on 21 December.
Appropriate action was taken in accordance with the EM&A
Manual. The sighting results were
presented in Table 4.1.

The EM&A Manual for the Project has been
updated by the ET to include the detailed arrangements of setting up a Community
Liaison Group, carrying out design audit, and monitoring of Persistent Organic
Pollutants during construction of the Project.
The updated EM&A Manual was revised accordingly to the comments
received from the EPD on 6th December 2007 and was submitted to the
EPD on 10th December 2007.
The ET will keep track on comments received from the EPD, if any, and
update the EM&A Manual
accordingly.
Baseline water
quality monitoring was conducted between 24 October and 30 October 2007 at six
designated monitoring stations (three impact stations and three control
stations) established for the Project in accordance with the EM&A Manual. The Final
Baseline Monitoring Report was
submitted to the EPD on 21 November and comments were received from the EPD on
6th December. A revised Final
Baseline Monitoring Report will be submitted to the EPD within the next
reporting period.
Key issues to be
considered in the next one month will include:
·
Dust
release and suppression;
·
Operation
of dredging activities; and
·
Water
quality monitoring and dolphin monitoring during the dredging activities.
Provided that
environmental mitigation measures including good on-site practises are properly
implemented, it is not expected that unacceptable adverse impacts will arise.
Based on the
water quality monitoring results recorded to date, it may be expected that
further exceedances in Turbidity and possibly Suspended Solids may be
recorded. However, as with those
recorded so far, it is not expected that such exceedances would be attributable
to Project Works. It is noted that
actions are underway to potentially revised the Action Limit Levels for
Turbidity and progress on these revisions will be summarised in the next Monthly Monitoring Report.
Work programme
for the next one month includes jetty platform works (non-piling), site works
(construction works for tank farm, operational and fire services buildings,
drainages, bund wall, security wall etc) and dredging operation. Weekly site inspections will be undertaken. Water quality, dolphin monitoring and marine
archaeological monitoring will be undertaken in accordance with the EM&A Manual.
