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 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 DEPs 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.

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 actions were required.

Site inspections were carried out by the ET on 5, 14, 19 and 28 August 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:

Water Quality

            On 5, 14 and 19 August 2009, stagnant water pools were observed in the drip trays of machinery or round drums. Stagnant pools of water were found in the bunding around the diesel tank and generator in the workshop area on 5 and 14 August 2009, in the bunding around the diesel drum near Tank 11 on 5, 14 and 19 August 2009, and in the bunding round the air compressor and diesel tank next to the pumping station on 19 August 2009. The Contractor was reminded to cover the diesel tank and generator in the workshop area with the tarpaulin during rain storms, clear water in the bunded areas and regularly clear stagnant water.

            On 19 and 28 August 2009, a stagnant pool of water was observed underneath the de-humidifier leading into Tank 8, due to a constant drip originating from the machine. The Contractor was advised to attach a pipe to the drip to dispose of water appropriately into the drainage system and to clear the stagnant water.

            On 5 August 2009, the water being pumped out of Tank 12 was not going into the drainage system. The Contractor was asked to source a longer hose so that water was directed into the drainage system.

            On 5 and 14 August 2009, the water hose leaving the sediment tank by Tank 12 was not going directly into the drainage system. The Contractor was reminded to move the pipe so that it went into the drainage system.

            On 14 August a bund stopper and some water pipes were found to be leaking. The Contractor was reminded to reseal the join and repair the pipes to keep them all in good working order.

            On 5, 14 and 19 August 2009, a sediment plume was observed at the drainage discharge outfall at the jetty area. After investigation, it was concluded that the plume was probably due to the heavy rain during the previous night and the disrepair of the sandbags and filters. The Contractor was reminded to repair the sandbags and filters on all the open drains and check the efficiency of the sediment tanks/ silt retention measures regularly, especially after heavy rain.

            On 5 August 2009, a thin film of oil was observed on the steps going down to the water in the jetty area. The Contractor was asked to investigate the source of the problem and clear the oil sheen as soon as possible.

            On 19 August 2009, a drain by the pumping station was found to be blocked, with a pool of water above it. The Contractor was reminded to repair the drain as soon as possible and ensure the whole drainage system was in good repair.

Waste/Chemical Management

            On 14 and 19 August 2009, the cement holding the bunding in place round the diesel tank and generator in the workshop area was found to be in a state of disrepair. The Contractor was advised to re-cement the bunding round the diesel tank and generator.

            On 5, 14 and 19 August 2009, stockpiles of construction waste were found accumulated without proper receptacles on the tank circular road in the tank farm area and/or inside Tank 10. The Contractor was reminded to clear the waste or provide bins for temporary storage as soon as possible.

            On 14 August 2009, empty paint cans were found strewn in the chemical storage area. The Contractor was reminded to separate these from the chemical waste and store them in the appropriate area.

            On 28 August 2009, the chemical waste storage containers were found to be without sufficient ventilation. The Contractor was reminded to cut ventilation holes in the storage containers.

With the exception of the above observations, 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.

3.2                                      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 D.

 

4                                            Environmental Monitoring

4.1                                      Air and Noise

Air and Noise monitoring is not required for the project.

4.2                                      Water Quality

No dredging activities were scheduled from 24 January 2009 onwards. Water quality monitoring was therefore not required for the reporting month.

4.3                                      POPs Monitoring

Persistent organic pollutants (POPs) monitoring was not required since there was no dredging operation during the reporting month.

4.4                                      Waste Management

According to EP Condition 3.3, the Contractors 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 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.

4.7                                      Land Contamination, Hazard to Life and Fuel Spill Risk

The ET and IEC verified updated design audit plan was 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.

4.8                                      Ecology

Dolphin Visual Monitoring

Dolphin visual monitoring was not required as no dredging works were scheduled for the reporting period.

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 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 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

5.1                                      Key Issues for the Next Month

Key issue to be considered in the next month will be:

       dust release and suppression; and,

       backfilling of rock armour over pipelines.

5.2                                      Impact Prediction for the Next Month

Provided that environmental mitigation measures including good on-site practises are properly implemented, it is not expected that unacceptable adverse impacts will arise.

5.3                                      Works and Monitoring Schedule for the Next Month

Work programme for the next month includes:

       backfilling and placing of rock armour works;

       riser connections at Sha Chau;

       jetty platform works (non-piling);

       site works (construction works for tank farm, roof truss, operational and fire services buildings, drainages, bund wall, security wall etc); and

       pre-commission and commissioning activities for Phase 1A (the first four tanks) .

Weekly site inspections will be undertaken.
