EXECUTIVE
SUMMARY
The construction
works for the Permanent Aviation Fuel Facility resumed on 9 July 2007. This thirty-seventh
monthly Environmental Monitoring and Audit (EM&A) report presents the
EM&A work carried out during the period from 1 November to 30 November
2009 in accordance with the EM&A
Manual.
Breaches of all Action and Limit Levels
Water quality
monitoring during dredging activities recorded no exceedance of Action or Limit
Levels for bottom Dissolved Oxygen (DO).
Exceedances of Depth-averaged DO were recorded on 13, 14, 15, 17, 21 and
23 November and of Depth-averaged Suspended Solids on 15, 17, 18 and 19
November. There were no exceedances of
Limit levels for Depth-averaged Turbidity during the reporting period but on 18
November there were four exceedances of Action Levels for Depth-averaged
Turbidity. Following review of data in
accordance with the procedures specified in the EM&A Manual, all these exceedances were considered to be due to natural
fluctuation rather than the Project Works.
Complaint Log
No environmental
complaints were received during the reporting period.
Notifications of any Summons
and Successful Prosecutions
No environmental summons or prosecutions were received in this reporting
period.
Reporting Changes
There were no reporting changes in the reporting period.
Future Key Issues

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.
The decision by
the EPD to grant the above Environmental Permit was, however, 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 EP-262/2007/A and
issued by the EPD on 30 November 2007. A
further Variation to the Environmental Permit was approved to allow dredging
works to continue until March 2008. As
such, EP-262/2007/A has been amended
to EP-262/2007/B and was issued by
the EPD on 27 February 2008.
The construction
works and EM&A requirements were resumed on 9 July 2007 following the
latest requirements of the EP-262/2007/B
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 thirty-seventh EM&A Report which
summarizes the monitoring results and audit findings for the EM&A programme
during the reporting period from 1
November to 30 November 2009.
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.
Initial marine dredging operations were completed on 23 January 2009 but
due to pipeline repairs, dredging works were resumed on 13 November 2009. Table 2.2 presents the cumulative
quantity of excavated materials from September 2008 up to 30 November
2009. Daily and cumulative dredging
production rates are illustrated in Figure 2.1.

According to the EP requirements, a Community Liaison
Group (CLG) was established within three months of commencement of construction
of the Project. The major duty of the
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 period, no meetings were organised by the CLG. The details of the CLG (including Membership and its Terms of
Reference) and the minutes of previous meetings can be found on the Project
website (http://www.paffhk.com).
Water quality
monitoring during dredging activities recorded no exceedance of Action or Limit
Levels for DO Bottom. Exceedances of
Depth-averaged DO were recorded on 13, 14, 15, 17, 21 and 23 November and of
Depth-averaged Suspended Solids on 13, 15, 17, 18, 19 and 21 November. There were no exceedances of Limit levels for
Depth-averaged Turbidity during the reporting period but on 18 November there
were four exceedances of Action Levels for Depth-averaged Turbidity. A summary of the exceedances occurring during
the reporting period is shown in Table
2.4 and a description of the actions taken following these non-compliances
is discussed in Section 3.2.

*Note: Action Level but not Limit Level 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.
No environmental
complaints were received during the reporting period. A summary of environmental complaints since
project commencement is presented in Annex D.
No summons was
received in this reporting period. A
summary of legal proceeding since project commencement is presented in Annex D
As no
environmental complaints were received over the last reporting period, no
follow-up actions were required.
Site inspections
were carried out by the ET on 6, 12, 19 and 26 November 2009. 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
·
On 26 November, the air compressor near the Jetty area was found without
a label or drip tray. The air compressor
was evidently not yet in operation, but the Contractor was advised to ensure it
had the correct label and a drip tray before starting operation.
Noise
·
On 12 November, the CNP permit showing at the main site entrance showed
an expiry date of 3 November 2009. The
Contractor was advised to put up the new permit that had been obtained.
Water Quality
·
On 6, 12 and 19 November, the sediment tanks near the middle, main
entrance were left uncovered and a possible breeding ground for
mosquitoes. The Contractor was advised
to cover the sediment tanks as soon as possible.
·
On 6 November, a pipe connection on the path leading from the main to
the middle entrance was found to be leaking.
The Contractor was asked to fix the connection as soon as possible.
·
On 6 November, water was observed in the bunding around the generator in
the Workshop area and on 19 November in the drip tray of the diesel drum near
the Workshop area. The Contractor was
advised to clear this immediately.
·
On 12 November, a thin oil film was observed on the seawater by the
jetty. Water coming out of the drainage
system appeared clean and it was concluded that the oil film was probably not
resulting from the PAFF site.
·
On 19 November, dirty water was found behind the painting area by Tank
8. The Contractor was advised to clear
the water as soon as possible.
Waste/Chemical Management
·
On 6, 12 and 19 November, scattered pieces of debris were found around
the Tank Farm areas, on 12 November a stockpile of debris and construction
waste was found just inside the middle entrance to the site and on 19 November
wire debris was found behind a lorry by Tank 10. The Contractor was advised to collect all
debris and dispose of it appropriately.
·
On 6 and 12 November, black plastic bags and hosepipes were found
deposited in the chemical waster storage area by Tank 10. The Contractor was advised to clear these to
the appropriate place as soon as possible.
·
On 19 November, the Contractor was advised to check the set-up of the
paint area near Tank 8 to ensure it was safe and there was no contamination of the
surrounding area. They were also advised
to ensure that all empty paint cans were stored in the chemical waste facility.
·
On 26 November, the dredging barge was inspected and there were
insufficient waste receptacles. The
Contractor was advised to ensure rubbish bins were provided on all levels of
the barge and that they were of adequate capacity.
·
On 26 November, oil was identified in the drip tray around the generator
aboard the grab dredger and there was an open plastic bucket of oil near the
generator. The Contractor was advised to
clear the drip tray immediately and cover the plastic bucket.
General Housekeeping
·
On 26 November, the electric hazard label on the generator aboard the
grab dredger was illegible. The
Contractor was advised to arrange for a new sign to be put in place.
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 no exceedance of Action or Limit Levels for DO Bottom. Exceedances of Depth-averaged
DO were recorded on 13, 14, 15, 17, 21 and 23 November and of
Depth-averaged Suspended Solids on 13, 15, 17, 18, 19 and 21 November. There were no exceedances of Limit levels for
Depth-averaged Turbidity during the reporting period but on 18 November there
were four exceedances of Action Levels for Depth-averaged Turbidity. A summary of the exceedances recorded during
the reporting period is shown in Section 2.7, Table 2.4 and graphical representations of the
results are presented in Annex G.
Descriptions of the actions taken following identification of
non-compliance are discussed below.
Although dredging operations were undertaken during
the reporting period, on examination of the results, it was concluded that all the exceedances described above were unlikely to be caused by the
Project for the following reasons:
·
Exceedances
were found at monitoring stations upstream and downstream of dredging vessels
that were not in operation (e.g. exceedance of Action Level of depth-averaged
DO on 13 November 2009 at IMO3 and IMO4).
The values were comparable to exceedances found at stations upstream and
downstream of operational dredging vessels on the same day (eg exceedance of
Action Level of depth-averaged DO on 13 November 2009 at IMO1).
·
Not
all parameters showed same trend of exceedances (e.g. on 14 November there were
exceedances of Depth-averaged DO at various stations, but there were no
exceedances of Bottom DO, Depth-averaged Turbidity and Depth-averaged Suspended
Solid (SS) results at the same stations at the same tide)
·
There
have also been exceedances recorded from previous monitoring periods when
dredging was not undertaken (e.g. 8 September 2008 with exceedances in DO
values; 10 February 2008 with exceedances in Depth-averaged Turbidity and in
SS).
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
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 13 November 2009. 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 Bottom dissolved oxygen (DO) levels
at all Impact Stations were compliant with the Action and Limit Levels
specified in the EM&A Manual. Concentrations of Depth-averaged Turbidity were
also compliant with Action and Limit levels with the exception of 18
November. Exceedances for Depth-averaged
DO and Suspended Solids were more frequent during the reporting period with
exceedances in 13, 14, 15, 17, 21 and 23 November for Depth-averaged DO and in
13, 15, 17, 18, 19 and 21 November for Depth-averaged SS. A review of the above exceedances concluded
that they were not attributable to Project works and were likely due to natural
variation (see Section 3.2 for
further details).
Biweekly
monitoring of water samples was conducted for Persistent Organic Pollutants (POPs) analysis on 25 November. Total PCBs, PAHs and DDTs were all below
detection limits. Monitoring results
and QA/QC
reports for the available POPs testing are presented in Annex H. The remaining results will be presented in
the next Monthly Report.
According
to EP Condition 3.3, the Contractor’s
revised Waste Management Plan (Revision 5) (WMP), which has been certified by
the ET and IEC, was submitted to the EPD on 5 November 2008.
The
Watching Brief Report, verified by
the Independent Environmental Checker, was submitted to the EPD and AMO on 9
May 2008.
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 weekly site
inspections included general audits on landscape and visual issues to ensure
that the site was in an orderly and 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. In 2007, the
Contractor submitted an updated design audit plan according to the EP
requirements. These were certified and
verified by the ET and IEC respectively and submitted to the EPD on 7 November
2007.
Pursuant to Condition 3.5 of the EP, the Contractor
submitted design drawings and supporting information according to the EP
requirements. The ET certified the
documents and submitted to the IEC for verification on 24 and 25 November 2009.
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 was
undertaken during dredging activities from when they started on 13 November
2009.
During the
reporting period, a total of four dolphin sightings were recorded. Since no dolphin sightings were recorded
within the exclusion zone, no action was considered necessary according to the EM&A Manual. The sighting locations and field records are
presented in Annex I.
The EM&A Manual for the Project was updated
by the ET to include the detailed arrangements of setting up a CLG, carrying
out design audit, and monitoring of Persistent Organic Pollutants during the
dredging phase of construction of the Project.
The revised EM&A Manual,
which was verified by the IEC, was submitted to the EPD on 1 April 2009.
The Final Baseline Monitoring Report was submitted to the EPD on 20
February 2008 and placed under the EIAO register.
Key issue to be
considered in the next month will be:
·
dust
release and suppression;
·
backfilling
of rock armour over pipeline;
·
dredging
operation for the repair of pipeline; 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 Depth-averaged Dissolved Oxygen, Suspended Solids and
possibly Turbidity may be recorded.
However, as with those recorded so far, it is not expected that such
exceedances would be attributable to Project Works.
Work programme
for the next month includes:
·
backfilling
and placing of rock armour works;
·
dredging
operation for the repair of pipeline;
·
riser
connections at Sha Chau;
·
jetty
platform works (non-piling);
·
site
works (construction works for tank farm, roof truss, drainages, bund wall,
security wall and emergency vehicle access road etc); and,
·
pre-commission
and commissioning activities for Phase 1A (the first four tanks).
Weekly site inspections,
water quality and dolphin monitoring will be undertaken in accordance with the EM&A Manual.
