Scope

This standard specifies the general principles, content, procedures, methods, and technical requirements for environmental risk assessment of phosphogypsum storage facilities, and is applicable to environmental risk assessment of phosphogypsum storage facilities during operation and those that have been closed. The qualitative environmental risk assessment framework for phosphogypsum storage facilities consists of three stages: preparation for environmental risk assessment of phosphogypsum storage facilities, classification of environmental risk levels for phosphogypsum storage facilities, and characterization of environmental risks for phosphogypsum storage facilities. For phosphogypsum storage facilities requiring risk assessment, by using the analytic hierarchy process, scores are given from three aspects: environmental hazard (H) of phosphogypsum storage facilities, environmental sensitivity (S) of the surrounding environment, and reliability of management methods (M). Then, using the environmental risk level classification model, the environmental risk of phosphogypsum storage facilities can be divided into three levels: high risk, medium risk, and low risk, and the environmental risk level can be characterized according to the rules.
