Abstract: The storage process of waste dyes and paints was focused on. Based on the groundwater transport and diffusion scenario and air diffusion scenario, the exemption limit values (ELVs) for the storage of paint slag, wastewater sludge, and waste ink and paint was figured out using environmental risk assessment methodology. The results showed that the exemption limit value of solid phase waste (paint slag and wastewater sludge) storage was too little for exemption management. For waste ink and paint storage, the exemption limit value was 262 kg/a under bucket package without cover, open or semi-closed storage yard, harden ground and anti-seepage scenario.
