Scope

Main technical content: This document is the output of the National Key Research and Development Program project "Research and Application of NQI Technical System for Identifying and Preventing Typical Heavy Metal Pollution in Metallurgical Industry Tailings Yards" (Project No.: 2020YFF0218300). To standardize the process of reusing land after remediating polluted sites in metallurgical tailings yards and prevent harm to public health and pollution of surrounding soil and groundwater during reuse, this technical specification is formulated in accordance with the provisions of the "Environmental Protection Law of the People's Republic of China", the "Notice of the State Council on Issuing the Action Plan for Soil Pollution Prevention and Control" (No. 31 of 2016), the "Trial Measures for Environmental Management of Polluted Sites", the "Guide for Environmental Investigation, Assessment, and Remediation of Industrial Enterprise Sites (Trial)", the "Technical Guidelines for Site Environmental Investigation", the "Technical Guidelines for Risk Assessment of Contaminated Sites", and the "Soil Pollution Prevention and Control Law", etc. This document takes into account the actual situation of tailings yards and formulates the overall requirements, work procedures, methods, contents, technical requirements, and risk control techniques for the safe reuse of soil after remediating polluted sites in metallurgical tailings yards and tailings ponds. This document is not applicable to environmentally sensitive areas such as water source protection areas and farmlands.
