THE NEED TO PROTECT THE HEALTH OF LOCAL RESIDENTS FROM THE POSSIBLE EFFECT OF AERIAL EMISSIONS OF PFA DUST AND LIQUID EMISSIONS, TOGETHER WITH THE SAFEGUARDING OF LOCAL MARICULTURE AND WILD LIFE HAD BEEN OF PARTICULAR CONCERN.
IN JANUARY, MR CHAMBERS HAD INFORMED THE LEGISLATIVE COUNCIL THAT AERIAL EMISSIONS OF PFA DUST WOULD BE CONTROLLED BY THE DELIVERY OF PFA IN SLURRY FORM, MINIMISING THE AREA OF PFA EXPOSED TO THE WIND; THE PROVISION OF PERMANENT FIXED WATER SPRAYING EQUIPMENT WITH A MOBILE BACKUP SYSTEM, THE CONTINUOUS SKIMMİNG OF THE LAGOON AND THE COVERING OF DRY PFA BY INERT MATERIAL AND SUBSEQUENT HYDROSEEDING.
HE ALSO TOLD MEMBERS THAT AIR QUALITY IN THE VICINITY WOULD BE CONTINUOUSLY MONITORED BY THREE SEPARATE MONITORING STATIONS.
REGARDING LIQUID EMISSIONS, PFA WOULD BE FORMED INTO SLURRY WITH SEA WATER AND WOULD BE PUMPED ALONG ONE OF A TWIN PIPELINES
INTO THE LAGOON SITE.
INSTEAD OF DISCHARGING THE BECANTRATE – AN UPPER AQUEOUS LAYER FORMED WHEN ASH PARTICLES SETTLE RAPIDLY TO THE BOTTOM OF THE LAGOONS - DIRECTLY INTO DEEP BAY, WHICH MIGHT LEAD TO CONTAMINATION OF OYSTER BEDS, IT WOULD BE PUMPED BACK THROUGH ANOTHER PIPELINE TO THE POWER STATION AT TAP SHEK KOK, BEFORE RELEASING IT INTO THE FAST FLOWING CURRENTS OF URMSTON ROAD THROUGH AN OUTFALL.
AS A CHECK ON THE EFFECTIVENESS OF THIS MEASURE. SEVEN MONITORING STATIONS ARE ALREADY OPERATING AND WOULD CONTINUE IN OPERATION THROUGHOUT THE LIFE OF THE LAGOONS.
AT FULL OPERATING CAPACITY, THE PFA PRODUCED FROM THE POWER STATIONS COULD REACH 4 000 TONNES A DAY, AND THE LAGOONS HAVE A TOTAL CAPACITY OF 7.5 MILLION CUBIC METRES OF PFA.
MORE FIRE STATIONS COMING ON STREAM
