8.1 Based on the findings of the review of potential environmental issues associated with land contamination in the EIA report, it was concluded that there are two identified areas within the works area having a potential of contaminated land. Prior to the commencement of site clearance / excavation works, a sampling and analysis programme shall be prepared and implemented where contamination is suspected.
8.2 The land contamination assessment would include sampling and analysis of soil / groundwater to confirm the presence and level of contamination (if any) in the proposed potential zones for site contamination investigation (Figure 8.1). The information obtained from the assessment would be used to determine the appropriate handling and disposal requirements of the excavated materials.
8.3 The sampling and analysis of soil and groundwater should be conducted in accordance with EPD’s requirements. A Contamination Assessment Plan (CAP) should be submitted to EPD for endorsement prior to conducting the contamination assessment works at the two proposed zones as shown in Figure 8.1. Based upon an endorsed CAP, a contamination assessment should be conducted and a Contamination Assessment Report (CAR) should then be compiled for EPD’s approval. If contamination is identified during the preparation of the CAR, a Remediation Action Plan (RAP) should be submitted to EPD for approval and site clean up works should be conducted before the construction works of the Project.
