S.6.8.1 Good site practices to minimise dust and other air

pollutants impacts during soil excavation, transportation,

loading and unloading the excavated contaminated soils

� Excavation profiles should be properly designed and executed.

� The excavation area should be limited to as small in size as possible and backfilled with clean and/or treated soil shortly after excavation work.

� The exposed excavated area shall be covered by the

tarpaulin during night time.

� The top layer soils shall be sprayed with fine misting of water immediately before the excavation.

� Stockpiling site(s) shall be lined with impermeable sheeting and bunded. Stockpiles shall be properly covered by impermeable sheeting to reduce dust and other air pollutants emission.

� Misting for the dusty material shall be carried out before being loaded into the vehicle.

� Any vehicle with an open load carrying area shall have properly fitted side and tail boards.

� Material having the potential to create dust shall not be loaded from a level higher than the side and tail boards and shall be dampened and covered by a clean tarpaulin.

� The tarpaulin shall be properly secured and shall extent at least 300 mm over the edges of the sides and tailboards. The material shall also be dampened if necessary before transportation.

� The vehicles shall be restricted to maximum speed of 10 km per hour and confined haulage and delivery vehicle to designated roadways insider the site. On-site unpaved roads shall be compacted and kept free of lose materials.

� Vehicle washing facilities should be provided at every vehicle exit point.

� The area where vehicle washing takes place and the section of the road between the washing facilities and the exit point should be paved with concrete, bituminous materials or hardcores.

� Every main haul road should be scaled with concrete and kept clear of dusty materials or sprayed with water so as to maintain the entire road surface wet.

� Every stock of more than 20 bags of cement should be covered entirely by impervious sheeting placed in an area sheltered on the top and the three sides.

� Every vehicle should be washed to remove any dusty materials from its body and wheels before leaving the construction sites.

� The solidification pit/area shall be provided with dust suppression measures.

� Handling and mixing of cement shall follow Air Pollution Control (Construction Dust) Regulation to limit cement emission.

� The bin should be covered during residence period after mixing process.

Operation of biopiling

� During the course of biopile formation, the stockpiled soils at the biopiles shall be covered by tarpaulin or low permeable sheet to avoid fugitive emissions of dust or any air pollutants from the biopiles affecting the surrounding environment and to minimise runoff from the stockpiled soils. Biopile(s) shall be covered by impermeable sheeting (such that no longer than 5m of a biopile shall be exposed to open air) to avoid fugitive emissions of dust or any pollutants from the biopile(s).

� Upon formation of a biopile, the biopile shall be covered by low permeable geotextiles to prevent dust emission and runoff.

� During the operation of biopile, the biopiles shall be fully covered to control the extraction of VOCs.

� Carbon absorber with 99% control efficiency shall be installed for the biopiling system to treat the off-gas prior to discharge and the location of the exhaust of the carbon filter should be sited as far away as possible from the nearby ASRs.

� Spent activated carbon of the carbon absorber shall be replaced regularly such that the VOC emission rate from the system is acceptable (i.e. the measured TVOC is below 20 ppm). The carbon adsorption system should also be monitored regularly to check the performance of the carbon filter.

� Gas samples at the exhaust of the carbon filter for VOCs should be monitored regularly. The biopile operation shall be terminated when unacceptable air quality is monitored at the site boundary. Resumption of biopiling will only be allowed after confirmation and implementation of appropriate mitigation measures.

S.7.8.2 Good site practices to be implemented:

� Only well-maintained plant should be operated on-site and plant should be serviced regularly during the construction program.

� Mobile plant, if any, should be sited as far away from NSRs as possible.

� Machines and plant (such as trucks) that may be in intermittent use should be shut down between works periods or should be throttled down to a minimum.

� Plant known to emit noise strongly in one direction should, wherever possible, be orientated so that the noise is directed away from the nearby NSRs.

� Material stockpiles and other structures should be effectively utilised, wherever practicable, in screening noise from on-site construction activities.

- � As no significant ecological impact on marine

habitats and associated wildlife is predicted, no necessary mitigation measure is considered as required in this assessment. The mitigation measures recommended in the water quality assessment to control water quality would serve also to protect marine ecological resources from indirect impacts and ensure no adverse impact on marine life would be resulted from the Project.
