When is a solid waste a hazardous waste?




Not quite.

According to 40 CFR 261.3, a solid waste becomes a hazardous waste when it exhibits one or more of the characteristics of hazardous waste identified by the EPA in 40 CFR 261.21-261.24 and/or meets any of the listed descriptions of hazardous waste found in 40 CFR 261.31-261.33.

Also, per 40 CFR 261.3, any mixture of a solid waste with a listed hazardous waste is considered a listed hazardous waste and all listed waste codes apply to the entire mixture, which means there is that much more listed hazardous waste to manage correctly.
