1 Introduction

Leighton Contractors (Asia) Limited (LCAL) has appointed ERM-Hong Kong, Limited (ERM) as the Environmental Team (ET) to implement the Environmental Monitoring and Audit (EM&A) programme for the Permanent Aviation Fuel Facility (the Project) during construction works.

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 28 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 EPD in February 2004.

The decision by 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 EP262/2007/A and issued by the EPD on 30 November 2007. A further Variation to the Environmental Permit has been 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 issued by the EPD on 27 February 2008.

The construction works and EM&A requirements resumed on 9 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.

2.6 Community Liaison Group Meeting

According to the EP requirements, a Community Liaison Group (CLG) was established within three months after 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. Whereas previously the CLG would meet quarterly, following their last meeting on 13 September 2009, it was agreed to meet every six months. Therefore, during the reporting period, no meetings were organised by the CLG. Details of the CLG (including Membership and its Terms of Reference) and the meeting minutes can be found on the Project website (http://www.paffhk.com).

2.7 Summary of Non-Compliance with the Environmental Quality Performance Limits

Water quality monitoring during dredging activities (13 November to 11 December 2009) recorded no exceedance of Action or Limit Levels for Bottom Dissolved Oxygen (DO). There were no exceedances of Limit levels for Depth-averaged Turbidity during the reporting period but on 18 November and 3 December, there were exceedances of Action Levels at four stations for Depth-averaged Turbidity. Exceedances of Depth-averaged DO were recorded on 13, 14, 15, 17, 21 and 23 November. Exceedances of Depth-averaged Suspended Solids were recorded on 15, 17, 18 and 19 November, and 3 and 5 December.

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 detailed in Section 3.2.

3 Environmental Issues and Actions

3.1 Previous Environmental Deficiencies and Follow-up Actions

As no environmental complaints were received over the last reporting period, no follow-up action was required.

Weekly site inspections were carried out by the ET on 7, 14, 21 and 28 October, 6, 12, 19 and 26 November, and 2, 10, 18, 23 and 30 December 2009. Overall, the site was in good orderly manner and no non-compliances were found. Environmental deficiencies and follow-up actions/mitigation measures were identified during the inspections and summarised in Table 3.1.

Table 3.1 Environmental Deficiencies (Observations) from Site Inspections during Reporting Period

Reporting Month	Observation	Follow-up Action
October 2009	Much of the Tank Farm area was unpaved.	The Contractor was reminded to regularly water the unpaved areas to avoid dust generation.
Black smoke was seen being emitted from a barge sitting offshore of the Jetty area.	The Contractor was advised to inspect or service the engine as soon as possible.
The exposed slope surfaces at excavation site near the main entrance were not sufficiently covered.	The Contractor was reminded to cover exposed surfaces by tarpaulin or planting vegetation to avoid dust generation.
Water was found leaking from Tank 11.	The Contractor was reminded to ensure the water drained adequately and was not left to accumulate in stagnant pools.
A stagnant pool of water was observed underneath the dehumidifier leading into Tank 8, and the hose leading from the dripping pipe was not leading to a drain.	The Contractor was advised to fill in the stagnant water pool and to ensure the hose from the pipe led to a drain.
Mosquito larvae were observed in the sediment tanks near the middle entrance (to Phase 1a).	The Contractor was advised to cover the sediment tanks as soon as possible.
The sea water near the Jetty area was turbid, which might have been due to sediment disturbance from the propeller of the barge operating in the shallow area.	Since the operation was temporary and the disturbance was localised, no remedial action was advised.
Water was observed in the bunding around the diesel tank and the generator respectively, in the workshop area.	The Contractor was advised to clear the water immediately.
Cleaning of Tank 11 caused water to collect at its base.	The Contractor was advised to clear or backfill the water as soon as the cleaning was completed.
The paper recycling bin near the main office area was starting to overflow.	The Contractor was advised to empty the bin and put the spare, new recycling bins out around the site.
The labels on the drums in the chemical waste storage area were observed to be damaged or absent.	The Contractor was advised to renew the labels.
Painting material without proper receptacles was found near the sediment tank near the middle entrance (to Phase 1a).	The Contractor was advised to clear this into the chemical waste storage area as soon as possible.
Scattered pieces of debris were found around the Tank Farm and Jetty areas.	The Contractor was advised to collect all debris and dispose of it appropriately.
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.
No fire extinguisher was found next to the generator by Tank 10.	The Contractor was reminded to put a fire extinguisher next to the generator as soon as possible.
November 2009	The air compressor near the Jetty area was found without a label or drip tray. The air compressor was evidently not yet in operation.	The Contractor was advised to ensure the air compressor had the correct label and a drip tray before starting operation.
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.
The sediment tanks near the middle entrance (to Phase 1a) were left uncovered and a possible breeding ground for mosquitoes.	The Contractor was advised to cover the sediment tanks as soon as possible.
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.
Water was observed in the bunding around the generator in the Workshop area and in the drip tray of the diesel drum near the Workshop area.	The Contractor was advised to clear this water immediately.
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.	No action necessary.
Dirty water was found behind the painting area by Tank 8.	The Contractor was advised to clear the water as soon as possible.
Scattered pieces of debris were found around the Tank Farm areas, a stockpile of debris and construction waste were found just inside the middle entrance to the site, and wire debris was found behind a lorry by Tank 10. Black plastic bags and hosepipes were also found deposited in the chemical waster storage area by Tank 10.	The Contractor was advised to collect all debris and dispose of it appropriately.
A temporary paint area had been set up by Tank 8.	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.
The dredging barge was inspected and there were insufficient waste receptacles.	The Contractor was advised to ensure that rubbish bins were provided on all levels of the barge, and that they were of adequate capacity.
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.
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.
December 2009	A sediment plume was observed in the run-off drainage near the Jetty area.	The Contractor was advised to settle the run-off via a sediment tank before being discharged.
Water was observed in the drip tray of the diesel drum outside the workshop area and in the air compressor by Tank 11.	The Contractor was advised to clear all this water as soon as practicable.
The bunding round the generator in the workshop area was found to have a pipe leaking water from inside to outside.	The Contractor was advised to bung the pipe as soon as possible.
The drainage system was not in operation as the sediment tanks had been removed due to the construction works.	The Contractor was advised to reinstate the sediment tanks and restore the drainage system as soon as possible as there had been some rain recently and there was some surplus water onsite.
General refuse had accumulated without receptacles in the tank farm area and debris in black plastic bags was found near the Jetty Area.	The Contactor was advised to remove and store all refuse in proper containers and to place black plastic bags of debris in a skip or remove them as soon as possible.
Empty paint cans were found in the chemical waste storage area. Drums with no labels and no drip trays were also found near the office block.	The Contractor was advised to place the empty paint cans in black plastic bags and label them appropriately and to label the drums and place them in drip trays.
The painting subcontractor’s chemical waste disposal trip tickets for disposal of their empty paint cans were not available for inspection.	The Contractor was advised to follow this up with the subcontractor as soon as possible to make them available.
The chemical waste storage by Tank 8 and by the offices was found to be full, some waste was observed outside the storage facility and a dead rat was also found under the black plastic bags.

The Contractor was advised to clear the oil as soon as possible.

Two oil drums were found on the grab dredger without drip trays.

The Contractor was advised to put the drums inside a trip tray as soon as possible.

Waste receptacles on the grab dredger were found to be of inadequate capacity.

The Contractor was advised to provide larger waste receptacles as soon as possible.

A leaking diesel pump was found on the grab dredger, with a plastic bucket below it to catch the drips.

The Contractor was advised to get the pump fixed as soon as possible.

A small amount of soil was observed outside the vehicle entrance on the site access road.

The Contractor was advised to clean it as soon as possible and to implement wheel-wash procedures properly.

A water pipe connection and another hosepipe behind Tank 11 were found to be leaking and producing stagnant pools of water.

The Contractor was asked to fix the leaking water and clear/fill the stagnant water as soon as possible.

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.

3.2 Description of Actions Taken in Event of Non-Compliance and Deficiency Reporting

A summary of the exceedances recorded during the reporting period is shown in Table 2.4 of Section 2.7 and graphical representations of the results are presented in Annex F. 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:

· Not all parameters showed the same trend of exceedance results at the same stations at the same tide (eg on 3 December there were exceedances of Depth-averaged Turbidity and Suspended Solids at various stations, but there were no exceedances of Bottom or Depth-averaged DO at any station throughout the day).

· 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).

· There have been incidents in the past in this area where exceedances have occurred despite the dredger not being in operation (eg 10 Feb 2008, exceedance in SS despite no dredging work; 17 and 22 Dec 2007, 4 and 5 Jan 2008, 6 and 10 Feb 2008, exceedances in Turbidity despite no dredging work).

Although the measured levels of Suspended Solids were particularly high at MPB1 on 3 December 2009, MPB1 station was located far away from the dredging operation at the time. As mentioned previously, there have also been incidents in the past in this area where exceedances have occurred despite the dredger not being in operation, it was concluded that the exceedances were unlikely to be due to the project works.

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.

3.3 Implementation Status on Environmental Protection Requirements

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.

4 Environmental Monitoring

4.1 Air and Noise

Air and Noise monitoring is not required for the project.

4.2 Water Quality

In accordance to the EM&A Manual, water quality monitoring was carried out during dredging activities, which commenced on 13 November 2009 and were completed on 11 December 2009. QA/QC reports for Suspended Solids testing and monitoring results have been presented in 37^th and 38^th Monthly EM&A Reports. Graphical presentations of the monitored parameter during the reporting period are included in Annex F.

Results of the monitoring demonstrated that all measured Bottom Dissolved Oxygen (DO) levels were compliant with the Action and Limit Levels specified in the EM&A Manual. Concentrations of Depth-averaged Turbidity were also all compliant with Limit levels but exceeded Action Levels on two days, 18 November and 3 December, at four stations. Exceedances of Depth-averaged DO were recorded on 13, 14, 15, 17, 21 and 23 November. Exceedances of Depth-averaged Suspended Solids were recorded on 15, 17, 18 and 19 November and 3 and 5 December. A review of the above exceedances concluded that they were not attributable to the Project works and were likely due to natural variation (see Section 3.2 for further details).

4.3 POPs Monitoring

Biweekly monitoring of water samples was conducted for Persistent Organic Pollutants (POPs) analysis and during the reporting period on 25 November and 8 December. Total PCBs, PAHs and DDTs were all below detection limits. Monitoring results and QA/QC reports for POPs testing have been presented in 37^th and 38^th Monthly EM&A Reports.

4.4 Waste Management

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.

4.5 Cultural Heritage

The Watching Brief Report, verified by the Independent Environmental Checker, was submitted to the EPD and AMO on 9 May 2008.

4.6 Landscape and Visual

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 has 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 orderly and acceptable manner.

4.7 Land Contamination, Hazard to Life and Fuel Spill Risk

The ET and IEC verified updated design audit plan which was submitted to the EPD on 7 November 2007.

Weekly site inspections covered the waste management aspects which included measures to prevent land contamination by chemical wastes.

4.8 Ecology

Dolphin Visual Monitoring

In accordance to EM&A Manual, dolphin monitoring was undertaken during dredging activities from 13 November 2009 to 11 December 2009.

During the reporting period, a total of eight dolphin sightings were recorded. Four sightings were recorded outside the exclusion zone while four sightings were recorded within the zone. Five sightings occurred during dredging, but only one occurred of these occurred within the exclusion zone. No action was considered necessary should dolphins are sighted within the zone during dredging according to the EM&A Manual. The sighting locations and field records are presented in Annex G.

4.9 EM&A Manual

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 (POPs) during construction of the Project. The revised EM&A Manual, which has been verified by the IEC, was submitted to the EPD on 1 April 2009.

4.10 Baseline Water Quality Monitoring

The Final Baseline Monitoring Report was submitted to the EPD on 20 February 2008 and placed under the EIAO register.

5 Future Key Issues and Conclusion

5.1 Key Issues for the Next Reporting Period

Key issues to be considered in the next reporting period will be:

· dust release and suppression; and

· backfilling of rock armour over pipelines.

5.2 Impact Prediction for the Next Reporting Period

Provided that environmental mitigation measures including good on-site practises are properly implemented, no unacceptable adverse environmental impacts are expected.

5.3 Works and Monitoring Schedule for the Next Reporting Period

Work programme for the next reporting period includes:

· backfilling and placing of rock armour works;

· riser connections at Sha Chau;

· jetty platform works (non-piling);

· site works (construction works for tank farmdrainages, bund wall, security wall, emergency vehicle access road etc); and,

· commissioning activities for Phase 1a (the first four tanks).

Weekly site inspections will be undertaken in accordance with the EM&A Manual.

5.4 Conclusion

The EM&A works were conducted throughout the construction period and the relevant monitoring was conducted in accordance with the EP’s requirements. Mitigation measures were used to minimise the environmental impacts, where appropriate. Some environmental deficiencies were observed during the site inspections and the Contractor implemented corrective action to mitigate the issues. Overall, the site was in an orderly manner.
