Land Contamination Assessment. 8.2.1 3 boreholes have been proposed at the immediate down gradient location from the petrol filling station within the boundary of the assessment area. The preliminary land contamination survey would include sampling and analysis of soil / groundwater to assess the baseline condition of the soil and groundwater within the assessment area and the potential fuel migration (if any) due to the presence of a nearby petrol filling station. The information obtained from the preliminary survey would be used to determine if a detailed site investigation is required and possible remediation options would be recommended after the SI results are obtained.
Land Contamination Assessment. Site re-appraisal is required for the identified potentially contaminated sites as well as other areas within the Project Boundary to address any change in land use that may give rise to potential land contamination issues as soon as the sites become accessible and a supplementary Contamination Assessment Plan (CAP) should be submitted and endorsed by EPD before site investigation. A Contamination Assessment Report (CAR) which includes the site investigation sampling and testing results will be prepared for EPD's agreement upon completion of the site investigation. If contamination is identified, Remediation Action Plan (RAP) shall be also prepared and submitted to EPD for agreement prior to the commencement of the remediation works. Upon completion of the remediation, a Remediation Report (RR) shall be submitted to EPD for agreement. No construction works of site should be carried out prior to the agreement of the RR.
Land Contamination Assessment. The land contamination assessment examined the potential contaminative land use within Project Boundary. The assessment involved desktop review, site surveys, the proposed environmental site investigation and their potential impacts to future land use. A total of 44 potentially contaminated sites were identified, of which over 90% of the potentially contaminated sites are currently used as vehicle repairing/dismantling workshops and open storage area. As all the sites are inaccessible, only preliminary site appraisal through peripheral site surveys was conducted. Land contamination causing insurmountable impacts would be unlikely due to the fact that potential contaminated area encroaching onto the Project boundary is small and there are proven and commonly adopted remediation methods to properly treat the contaminants potentially found in the site. Site re-appraisal is required for the identified potentially contaminated sites as well as other areas within the Project Boundary to address any change in land use that may give rise to potential land contamination issues as soon as the sites become accessible and a supplementary Contamination Assessment Plan (CAP) should be submitted and endorsed by EPD before site investigation. A Contamination Assessment Report (CAR) which includes the site investigation sampling and testing results will be prepared for EPD's agreement upon completion of the site investigation. If contamination is identified, Remediation Action Plan (RAP) shall be also prepared and submitted to EPD for agreement prior to the commencement of the remediation works. Upon completion of the remediation, a Remediation Report (RR) shall be submitted to EPD for agreement. No construction works of site should be carried out prior to the agreement of the RR.
