Breaches of all Action and Limit Levels

Exceedance of the Action Limit = Level for Depth-averaged Dissolved Oxygen (DO) was found on 4, 8, 9, 10, 11 and 12 September 2008 while exceedance<= /span> of= the Action Limit Level for Bottom DO was found on 9, 10, 11 and 12 September 2008.  Ex= ceedance of Action Level of Suspended Solids was found on 4 and 18 September 2008.  Following review of data in accord= ance with the procedures specified with the EM&A Manual, these exceedances were considered likely due to natural fluctuation from the Pearl River discharge rather than the Project Works.

1&nb= sp;            =             &nb= sp;            =       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 t= he 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 Variatio= n 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-139/20= 02/A) was granted by EPD in February 2004.

However= , the decision by 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 con= struction works were stopped following the Judgement of the Court of Final Appeal of = July 2006.  As such, in order to co= ntinue 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 rev= ised 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.

It shou= ld be noted that at the time of reporting, a further Variation to the Environment= al Permit has been approved, primarily to allow for dredging works to continue during March 2008.  As such, EP-262/2007/A has been amended to = EP-262/2007/B and issued by the EP= D on 27 February 2008.

The con= struction works and EM&A requirements resumed on 9 July 2007 following the latest= requirements of the EP-262/2007 and EM&A Manual.&nb= sp; 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.

3.2          = ;            &n= bsp;            = ;   Descripti= on of Actions Taken in Event of Non-Compliance and Deficiency Reporting

Water q= uality monitoring during dredging activities recorded exceedances= of the Action Limit Level for Depth-averaged Dissolved Oxygen (DO) on 4, 8, 9,= 10, 11 and 12 September 2008.  The= re were exceedances of the Action Limit Level for = Bottom DO on 9, 10, 11 and 12 September 2008.&nbs= p; Exceedance of the Action Level of Suspen= ded Solids was found on 4 and 18 September 2008.  Details of ex= ceedance were presented in the monitoring results as Annex G. 

Althoug= h dredging operations were undertaken during the reporting period, the exceedances were unlikely to be caused by the Project and were considered to be an isol= ated case due to the following reasons:

·         Exceedance of the Action Limit Level for depth-averaged D= O was found on 8 September when no dredging was undertaken. These values were comparable to those of days with dredging operations; and,

·         Depth-averaged Turbidity did not show the same trend of exceedances indicating no potential relationship to a sediment plume generated by dredg= ing activities.

The exceedance was hence considered to be isolated case a= nd may likely be due to the regional natural fluctuation.

As per = the requirements of the EM&A Manual= , the incident was notified to the Franchisee’s Site Representative, the Contractor and the Independent Environmental Checker upon identification of= an exceedance.

The tem= poral 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.

= Dissolved Oxygen

During = impact monitoring, depth-averaged DO and bottom DO levels at all stations are generally comparable with those levels recorded during the baseline monitoring.  It is noted that = there appeared to be a decreasing trend in both DO levels at Impact Stations betw= een 8 and 12 September, however, as this pattern was also observed in both upst= ream and control stations, it is considered unlikely that these levels are attributable to Project works. 

= Suspended Solids

During = impact monitoring on the flood tide, SS levels at all stations were found to be generally comparable with those recorded during the baseline monitoring.  An exception was noted on 4 and 18 September where maximum levels were higher than those recorded during other monitoring events.  As levels returned to levels comparable with other monitoring events the following da= y, such fluctuations are not considered to be of a concern but rather isolated= events.  Furthermore, it is noted that upst= ream Control Station C2 also recorded similar high levels on 5 September at mid = ebb, indicating potentially natural fluctuations.

Based o= n the above, it is likely that the waters in the vicinity of the works site are influenced by other factors, such as natural fluctuations of DO and SS obse= rved in the Pearl River Estuary.

5.1   &= nbsp;           &nbs= p;            &= nbsp;         Key Issue= s for the Next Reporting Period

Key iss= ues to be considered in the next one month will be:

·         Dust release and suppression;

·         Operation of dredging activities; and,

·         Water quality monitoring and dolphin monitoring during the dredging activities.

5.2   &= nbsp;           &nbs= p;            &= nbsp;         Impact Prediction for = the Next Reporting Period

Provide= d that environmental mitigation measures including good on-site practises are prop= erly implemented, it is not expected that unacceptable adverse impact will arise= .

Based o= n the water quality monitoring results recorded to date, it may be expected that further exceedances in Dissolved Oxygen and pos= sibly 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.

5.3          = ;            &n= bsp;            = ;   Works and Monitoring Schedule for the Next Reporting Period

Work pr= ogramme for the next reporting period includes jetty platform works (non-piling), site works (construction works for tank farm, operational and fire services buildings, pump platform, drainages, bund wall, security wall etc) and dred= ging operation.  Weekly site inspec= tions will be undertaken in accordance with the EM&A Manual.     

5.4          = ;            &n= bsp;            = ;   Conclusio= n

The EM&= amp;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 we= re observed during the site inspections and the Contractor implemented correct= ive action to mitigate the issues.  Overall, the site was in an orderly manner.
