T/CQSES 06-2023 Recommendations for long-term regulation of soil safety after remediation

Scope

Scope: This document applies to soils with contaminant concentrations exceeding the screening values for soil pollution risk in Class I land use areas as specified in GB 36600 after remediation, and to the long-term supervision of their safe utilization upon leaving the site. Soils that have not been remediated but exceed the screening values for soil pollution risk in Class I land use areas as specified in GB 36600 may refer to this document for long-term supervision of their safe utilization upon leaving the site. This document does not apply to the long-term supervision of the safe utilization of soils containing radioactive substances and pathogenic biological contaminants after remediation. Main technical content: This document specifies the content, procedures, methods, and technical requirements for long-term supervision of the safe utilization of remediated soils. Based on the risk characteristics of remediated soils, it proposes management measures and requirements for safe utilization in the stages of transfer, temporary storage, and utilization. For three utilization methods, including backfilling utilization, greening utilization, and building material utilization, it specifies the objects, locations, cycles, and frequencies of long-term environmental monitoring of remediated soils, the content of data statistics and analysis, and institutional control measures. It also clarifies the conditions and measures for evaluating and responding to the results of long-term supervision.
