trucks and drum mixers and similar equipment should be recycled wherever
practicable. To prevent pollution
from wastewater overflow, the pump sump of any wastewater recycling system
will be provided with a standby pump of adequate capacity. Under normal circumstances, surplus wastewater from
the concrete batching will be treated in silt removal and pH adjustment
facilities before it is discharged into foul sewers. Discharge of this wastewater into
storm drains will require more elaborate treatment and regular testing
checks. Surface run-off will be
separated from the concrete batching plant as to the extent practical and
diverted to the stormwater drainage system. Surface run-off contaminated by
materials in the concrete batching plant will be adequately treated before
disposal into stormwater drains. |

exclusion zone within a radius of 250 m from the pipeline dredging vessel will

be scanned around the dredger for at least 30 minutes prior to the start of
dredging. If cetaceans are
observed in the exclusion zone for a continuous period of 30 minutes,
dredging will be delayed until they have left the area. As per previous practice in Hong Kong,
should cetaceans move into the dredging area during dredging, it is
considered that cetaceans will have acclimatised
themselves to the works therefore cessation of dredging is not required. Except the pipeline section along Urmston Road (waters of busy marine traffic), dredging
works will be restricted to a daily maximum of 12 hours with daylight

technically feasible to reduce the visibility of the terminal. In addition to the landscape mitigation plantings
proposed in the EIA report, appropriate new plantings will be installed where
possible, to help integrate the new structures into the surrounding
landscape. Security lighting of the site boundary - These will
generally be spot lights mounted on the external fencing and will have the
beams directed towards the ground. General access lighting - This will provide safe
access and operational lighting conditions around the site. Baffles will be fitted where possible to reducing
