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 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 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 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.

1.1                                      Purpose of the Report

This is the eleventh EM&A Report which summarizes the monitoring results and audit findings for the EM&A programme during the reporting period from 1 July to 30 September 2009.

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 3, 10, 16, 21 and 31 July 2009, 5, 14, 19 and 28 August 2009, and 2, 10, 18, 23 and 28 September 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

July 2009

Unpaved areas were not watered regularly

The Contractor was reminded to water regularly on the unpaved areas to avoid dust generation.

Stagnant water pools were observed in the drip trays of machinery, in the tank farm area, near the tanks, in the new wheelwash near the pump platform and in the bunding around diesel drums.

The Contractor was reminded to regularly clear stagnant water and check the efficiency of the drainage system,.

 

Water exiting the sedimentation tank near the temporary exit on the western side of the site was observed to be muddy which may also have lead to a muddy discharge observed in the marine area.

The Contractor was reminded to ensure the tank functions properly so that the site runoff can be settled before discharge.

A slight sediment plume was observed at the drainage discharge outfall at the jetty area.

The Contractor was reminded to check efficiency of the septic tanks regularly, especially after heavy rain.

Leaking water was found coming from the tap water system next to the workshop, a hose pipe near the jetty area and two pressure pumps.

The Contractor was reminded to maintain tap water systems in good condition, repair the leaking hose-pipe and keep the pumps in good condition, all to avoid accumulation of stagnant water.

General and construction wastes such as paper waste, aluminium cans and plastic bottles were accumulated in the tank farm area, the workshop area and near the operation building without proper receptacles.

The Contractor was reminded to clear the waste or provide bins for temporary storage as soon as possible and also to provide recycling bins where appropriate.

 

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 designated area.

Chemical waste drums were found to have accumulated without labels and the drip trays were not in good condition.

The Contractor was reminded to clear the waste drums and replace the drip trays as soon as possible.

August 2009

Stagnant water pools were observed in various areas (eg drip trays machinery (air compressor), the diesel tank and drums, and under the dehumidifier by Tank 8)

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. The contractor was also reminded to attach a pipe to the dripping pipe coming from the dehumidifier to ensure the water was disposed of properly and not left to accumulate in a stagnant pool.

Water being pumped out of Tank 12 was not going into the drainage system and the water hose leaving the sediment tank by Tank 12 was not going directly into the drainage system.

The Contractor was asked to source a longer hose so that water being pumped from Tank 12 was directed into the drainage system and ensure the pipe was directed into the drainage system.

A bund stopper and some water pipes were found to be leaking in the Tank Farm area.

The Contractor was reminded to reseal the join and repair the pipes to keep them all in good working order.

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.

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.

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.

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.

 

Empty paint cans were found strewn in the chemical storage area.

The Contractor was reminded to separate the paint cans from the chemical waste and store them in the appropriate area.

The chemical waste storage containers were found to be without sufficient ventilation.

 

The Contractor was reminded to cut ventilation holes in the storage containers and install ventilation windows.

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.

 

September 2009

Black smoke was seen regularly being emitted from the rock-filling barge.

The contractor was advised to inspect/service the engine as soon as possible..

Unpaved areas were not watered regularly

 

The Contractor was reminded to water regularly the unpaved areas to avoid dust generation

Oil sheen was observed in the bunding around the diesel tank in the Workshop area.

The Contractor was advised to clear the oily water as soon as possible and dispose of the contaminated water appropriately.

Stagnant pools of water were observed underneath the de-humidifier leading into Tank 8, due to a constant drip originating from the machine. These pools were also observed around the hose and dripping pipe.

The Contractor was advised to secure the hose to the dripping pipe, ensure the pipe led into a drain and clear the stagnant water as soon as possible.

The water hose leaving the sediment tank by Tank 10 was not going directly into the drainage system.

The Contractor was reminded to move the pipe so that it went into the drainage system

Stagnant water pools were observed in the bunding around the diesel drum near Tank 11, in the bunding round the air compressor near Tank 11, in the bunding around the generator near Tank 10 and in the Tank Farm area, some with white cooling agent in it.

The Contractor was reminded to clear water in the bunded areas and regularly clear stagnant water.

 

Water was observed pouring out of the water tank by the wheel washing facility, not leading into a drain.

The Contractor was advised to pipe the water into a drain or run it through a sediment tank.

 

Empty paint cans were found strewn next to Tank 8.

The Contractor was reminded to place the paint cans in an appropriate receptacle and dispose of them appropriately.

The chemical waste storage container by the Workshop was leaking slightly from the ceiling.

The contractor was advised to repair the leak as soon as possible.

 

The chemical waste storage containers were found to be without sufficient ventilation.

The Contractor was reminded to install ventilation windows in the storage containers.

The waste paper recycling bins were found to be overflowing and the skip by Tank 8 was found to be full.

The Contractor was advised to arrange for the collection of this waste as soon as possible.

A small container of lubricant was found in the chemical waste storage behind the Workshop area.

The Contractor was advised to pour this into the big drum of chemical waste as soon as possible.

 

Stockpiles of construction waste were found accumulated without proper receptacles near the chemical waste storage between the Workshop area and Tank 10, outside the exit from the Jetty area and outside the entrance between the main entrance and the Jetty area entrance.

The Contractor was reminded to clear the waste or provide bins for temporary storage as soon as possible
