Contamination
Assessment Report
7.1.1
Risk-Based Remediation
Goals (RBRGs) for Industrial have been adopted for the “Main Storeroom &
Workshops” and the laboratory results for the sampling works (conducted between
30 June 2021 to 16 July 2021) show that there are no exceedances of the adopted
RBRGs for the “Main Storeroom & Workshops”. As no contaminated soil and
groundwater was found within the “Main Storeroom & Workshops”, no remediation
actions are required for contaminated soil and groundwater for the scheduled
land use of the “Main Storeroom & Workshops”. Their findings are summarized
in Contamination Assessment Report (CAR) and submitted to EPD on 1 November
2021.
7.1.2
Risk-Based Remediation
Goals (RBRGs) for Industrial have been adopted for the “Mechanical Workshop”
and the laboratory results for the sampling works (conducted between 23 July
2021 to 4 August 2021) show that there are no exceedances of the adopted RBRGs
for the “Mechanical Workshop”. As no contaminated soil and groundwater was
found within the “Mechanical Workshop”, no remediation actions are required for
contaminated soil and groundwater for the scheduled land use of the “Mechanical
Workshop”. Their findings are summarized in Contamination Assessment Report
(CAR) and submitted to EPD on 23 November 2021.
7.1.3
Risk-Based Remediation
Goals (RBRGs) for Industrial have been adopted for the “Waste Storage Area” and
the laboratory results for the sampling works (conducted between 24 November
2021 to 6 January 2022) show that there are no exceedances of the adopted RBRGs
for the “Waste Storage Area”. As no contaminated soil and groundwater was found
within the “Waste Storage Area”, no remediation actions are required for
contaminated soil and groundwater for the scheduled land use of the “Waste
Storage Area”. Their findings are summarized in Contamination Assessment Report
(CAR) and submitted to EPD on 29 April 2022.
7.1.4
Risk-Based Remediation
Goals (RBRGs) for Industrial have been adopted for the “SAS Thickener House-1”
and the laboratory results for the sampling works (conducted between 13 April
2022 to 16 May 2022) show that there are no exceedances of the adopted RBRGs
for the “SAS Thickener House-1”. As no contaminated soil and groundwater was
found within the “SAS Thickener House-1”, no remediation actions are required
for contaminated soil and groundwater for the scheduled land use of the “SAS
Thickener House-1”. Their findings are summarized in Contamination Assessment
Report (CAR) and submitted to EPD on 6 July 2022.
7.1.5
Risk-Based Remediation
Goals (RBRGs) for Industrial have been adopted for the “SAS Thickener House-2”
and the laboratory results for the sampling works (conducted between 15
February 2023 to 23 February 2023) show that there are no exceedances of the
adopted RBRGs for the “SAS Thickener House-2”. The laboratory results are
compared against the adopted RBRGs and soil saturation limit (Csat) for soil samples and the adopted RBRGs and the
solubility limits for groundwater samples. No exceedance of RBRG are recorded for both soil samples and groundwater samples.
Furthermore, no exceedance of the soil saturation limit are
recorded for soil samples. However, the exceedances of solubility limits for
PCRs (C9-C16) are recorded for groundwater samples collected at BH-18, BH-19,
BH-20 and BH-21; and also PCRs (C17-C35) for BH-21. As
no non-aqueous phase liquid (NAPL) was observed during sampling, no further
sampling and remediation are required. As no contaminated soil and groundwater
is found within the “SAS Thickener House-2”, no remediation actions are
required for contaminated soil and groundwater for the scheduled land use of
the “SAS Thickener House-2”. Their findings are summarized in Contamination
Assessment Report (CAR) which was certified by ET Leader and verified by IEC on
31 May 2023 and submitted to EPD on 19th June 2023.
7.1.6
Risk-Based
Remediation Goals (RBRGs) for Industrial have been adopted for the “Screening
Press House” and the laboratory results for the sampling works (conducted
between 19 August 2024 to 20 August 2024) show that there are no exceedances of
the adopted RBRGs for the “Screening Press House”. As no contaminated soil and
groundwater was found within the “Screening Press House”, no remediation
actions are required for contaminated soil and groundwater for the scheduled
land use of the “Screening Press House”. Their findings are summarized in
Contamination Assessment Report (CAR) and submitted to EPD on 29 October 2024.
