DEVELOPMENT OF CODISPOSAL FACILITY UNDER STUDY
*****
THE ENVIRONMENTAL PROTECTION DEPARTMENT, IN PLANNING FOR THE PROPER DISPOSAL OF TOXIC, HAZARDOUS AND DIFFICULT (THD) WASTES, IS WORKING ON A SCHEME TO DEVELOP JUNK BAY CONTROLLED TIP AS THE MAJOR CODISPOSAL FACILITY IN HONG KONG.
+THE DEVELOPMENT OF SUITABLE DISPOSAL FACILITIES FOR HAZARDOUS WASTES IS ESSENTIAL IF HONG KONG IS TO AVOID THE EXTENSIVE POLLUTION THAT HAS RESULTED IN OTHER COUNTRIES FROM INDISCRIMINATE DISPOSAL, SAID MR M. J. STOKOE, PRINCIPAL ENVIRONMENTAL PROTECTION OFFICER RESPONSIBLE FOR LIQUID AND SOLID WASTE CONTROL.
HE WAS COMMENTING ON A REPORT SUBMITTED BY CONSULTANTS INVESTIGATING THE DEVELOPMENT OF A CODISPOSAL FACILITY.
BINNIE AND PARTNERS (HK) WAS COMMISSIONED LAST YEAR TO CARRY OUT AN EXPERIMENTAL STUDY ON THE CODISPOSAL OF THD WASTES WITH MUNICIPAL WASTE UNDER LOCAL CONDITIONS.
THE CONSULTANTS ARE EXAMINING VARIOUS TYPES OF THD WASTES SUITABLE FOR CODISPOSAL BY SETTING UP LABORATORY SCALE AND FIELD SCALE EXPERIMENTS.
THEIR WASTE MANAGEMENT REVIEW REPORT PRESENTS INTERIM RESULTS AND RECOMMENDATIONS WHICH ARE REQUIRED FOR SETTING UP A CODISPOSAL FACILITY IN HONG KONG BASED ON EXPERIMENTAL WORK CARRIED OUT SO FAR AND ON THE EXPERIENCE OF CODISPOSAL IN OTHER COUNTRIES. THE EXPERIMENTAL WORK BEING CARRIED OUT HERE WILL ESTABLISH AN ACCURATE ASSESSMENT UPON WHICH TO PLAN CODISPOSAL LOCALLY.
AT THE SITE PLANNING AND DESIGN STAGE, SITE INVESTIGATION IS REQUIRED TO ESTABLISH THE HYDROLOGICAL-HYDROGEOLOGICAL CONDITIONS AND OFF-SITE INVESTIGATIVE BOREHOLES MIGHT BE REQUIRED FOR DETAILED SITE ASSESSMENT.
F1
THE BOREHOLES COULD BE USED FOR DEVELOPING A DATABASE ON GROUNDWATER QUALITY AND CONTINUED MONITORING OF THEM AFTER SITE OPERATION BEGINS WOULD PROVIDE DATA FOR ASSESSMENT OF ANY LIKELY GAS MIGRATION-LEACHATE CONTAMINATION PROBLEMS.
THERE ARE SPECIFIC REQUIREMENTS FOR OPERATING CODISPOSAL FACILITIES AND THESE INCLUDE A SITE LABORATORY, A WASTE RECEPTION AND SAMPLING AREA, AND A TEMPORARY STORAGE FACILITY. A CHEMIST WOULD BE REQUIRED TO UNDERTAKE THE DUTIES OF SUPERVISION OF WASTE SAMPLING AND ANALYSIS, SUPERVISION OF CODISPOSAL OPERATION, MAINTAINING PROPER SITE RECORDS, REVISION OF LOADING RATES AND ADVISING ON CODISPOSAL AREAS.
