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.

It should be noted that at the time of reporting, a further Variation to the Environmental 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 EPD on 27 February 2008.

The construction works and EM&A requirements were resumed on 9th 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 complaint was received over the last reporting period, no follow-up action was required.

Weekly site inspections were carried out by the ET on 3, 11, 17 and 25 April 2008. 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.

            During the site inspection on 25 April 2008, an open stockpile of sand was spotted adjacent to the wall of the operation building under construction. The Contractor was recommended to cover up unused piles with impervious sheets whenever possible to avoid wind erosion.

            During the site inspection on 11 April 2008, a worker was observed cutting a wooden beam with an improper equipment, resulting in the generation of excessive dust and smoke. The Contractor was recommended to use suitable tools for respective work tasks in order to minimize air quality impacts.

Noise

            No noisy activities that generated excessive noise were observed during the audit.

            All air compressors inspected 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 observed during the audits.


Waste Management

            During the site inspection on 25 April 2008, construction and general wastes were mixed and piled on the ground outside the operation building. The Contractor was recommended to segregate wastes in an orderly manner and to provide suitable waste skips for temporary waste storage in accordance to the waste management plan developed from the approved EIA.

            During the site inspection on 3 April 2008, the general waste skip outside the operation building was observed to be full. The Contractor was reminded to clear wastes regularly. Ad hoc collection should be arranged when large quantities of wastes were generated in between regular collections to avoid overfilling waste skips.

            Oil stains were observed near the main chemical waste storage in the surcharge area and on the access road in between the surcharge area and the tank farms during the site inspection on 25 April. The Contractor was recommended to implement clean up practices when oil spills were identified on site.

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.

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 1 April 2008 onwards. Water quality monitoring was therefore not required for the reporting month.

4.3                                      POPs Monitoring

No POPs monitoring was undertaken since there was no dredging operation during the reporting month. POPs results of previous monitoring month (24 March 2008) were received during the reporting month and all POPs parameters (ie total PCBs, total DDTs and total PAHs) were below detection limits, except the total PAHs of Control Station C1 during mid-flood tidal condition. As C1 is a Control Station, such levels were not considered to be attributable to works. Monitoring results and QA/QC reports for POPs testing are presented in Annex E.

4.4                                      Waste Management

The Contractors revised Waste Management Plan (Revision 4) (WMP) was submitted to the EPD on 20th September 2007.

4.5                                      Cultural Heritage

A marine archaeological Watching Brief of two sub-surface anomalies was implemented from 21st to 28th February 2008. No archaeological sites or relics were found and it was considered by the licensed Marine Archaeologist that the anomalies have no cultural heritage significance. No additional mitigation measures were thus required to be implemented by the PAFF project in regard to the anomalies SS1 and SS2.

The details and findings of this watching process are presented in the Watching Brief Report, currently under review by the Independent Environmental Checker prior to submission to EPD and AMO for review.

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 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.

4.7                                      Land Contamination, Hazard to Life and Fuel Spill Risk

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.

4.8                                      Ecology

Dolphin Visual Monitoring

In accordance with EM&A Manual, dolphin monitoring has been undertaken during dredging activities since 17 December 2007 until 31 March 2008. Dolphin visual monitoring was suspended from 1 April 2008 as no dredging works were scheduled for the reporting period. No monitoring findings are therefore available for the month of April.

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 during construction of the Project. The updated EM&A Manual was revised accordingly to the comments received from the EPD on 6 December 2007 and was submitted to the EPD on 10 December 2007. Comments were received from the EPD on 22 January 2008. The ET will update the EM&A Manual accordingly within the next reporting period.

4.10                                  Baseline Water Quality Monitoring

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 was submitted to the EPD on 20th February 2008 with no further comments received and later placed under the EIAO register.

 

5                                            Future Key Issues

5.1                                      Key Issues for the Next One Month

It should be noted that dredging activities have been suspended from 1st April onwards and are tentatively scheduled to resume in September 2008. No dredging operation will be undertaken in the next reporting period. As such, the key issue to be considered in the next one month will be:

         Dust release and suppression.

5.2                                      Impact Prediction for the Next One 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 One Month

Work programme for the next one month includes jetty platform works (non-piling) and site works (construction works for tank farm, operational and fire services buildings, drainages, bund wall, security wall etc). Weekly site inspections will be undertaken.
