LANDFILLS INVESTIGATED FOR RESTORATION PLANNING
THE
NINE COMPLETED AND FOUR OPERATING LANDFILLS IN THE TERRITORY HAVE ALL BEEN INVESTIGATED TO PROVIDE THE DATA NEEDED FOR PLANNING THEIR PROPER RESTORATION, WHICH WILL ALLOW THE LAND TO BE PUT TO USE AGAIN.
THIS WAS STATED BY THE SECRETARY FOR PLANNING, ENVIRONMENT AND LANDS, MR TONY EASON, IN A WRITTEN REPLY TO A QUESTION BY THE HON FUNG CHI-WOOD IN THE LEGISLATIVE COUNCIL TODAY (WEDNESDAY).
AMONG THE LANDFILLS, THE ONE AT SAI TSO WAN HAS FACILITIES TO EXTRACT LANDFILL GAS AND SAFELY BURN IT. THE THREE NEW STRATEGIC LANDFILLS WHICH WILL BE COMMISSIONED WITHIN THE NEXT FEW YEARS WILL BE PROVIDED WITH GAS CONTROL AND COLLECTION AND DISPOSAL SYSTEMS TO THE LATEST INTERNATIONAL STANDARDS.
MR EASON SAID DURING THESE INVESTIGATIONS IT HAD BECOME CLEAR THAT, WHILE NONE OF THE SITUATIONS WAS HAZARDOUS, GAS CONTROL SYSTEMS COULD USEFULLY BE INSTALLED AT SOME SITES BEFORE FULL-SCALE RESTORATION WORKS WERE UNDERTAKEN.
DURING THE NEXT FEW MONTHS, GAS CONTROL WORKS WOULD START AT THE JORDAN VALLEY, SHUEN WAN AND GIN DRINKERS BAY (KWAI CHUNG PARK) LANDFILLS AT A COST OF AROUND $20 MILLION.
"THIS WILL ENSURE THAT THE AREAS AROUND THESE LANDFILLS SAFE FROM GAS HAZARDS.
THE
ARE
"THE PROGRAMME OF THE FULL-SCALE RESTORATION WORKS DEPENDS UPON AVAILABILITY OF FUNDS AND THE TIME TAKEN FOR EACH LANDFILL TO BE
COMPLETED.
"NEVERTHELESS, ALL THE EXISTING LANDFILLS SHOULD BE COMPLETED AND RESTORED WITHIN THE NEXT FOUR YEARS, MR EASON SAID.
T
MR EASON NOTED THAT A MIXTURE OF LANDFILL GAS AND OXYGEN COULD IGNITE UNDER CERTAIN CIRCUMSTANCES.
"HOWEVER, ENGINEERING MEASURES, SUCH AS VENTING AND FLARING, EITHER ALREADY TAKEN OR UNDER CONSIDERATION, SHOULD PREVENT THESE CIRCUMSTANCES FROM ARISING," HE SAID.
REGULAR GAS MONITORING WAS UNDERTAKEN TO ENSURE PUBLIC SAFETY ALL SITES, HE SAID, ADDING THAT THERE WAS NO CAUSE FOR CONCERN
AT DATE.
