Here is an example(we used this to characterize shotblast dust)
1) Is this or will this become a solid waste(see 40 CFR 261.2)?
Yes-plan to dispose of material.
2) Is this excluded from the hazardous waste regulations(see 40 CFR 261.4)?
No.
3) Is this a listed hazardous waste(see 40 CFR 261, subpart D)?
No.
Is this a characterized hazardous waste(see 40 CFR 261 subpart C)?
Complete the following by either (1) Testing the waste according to the methods set forth in Subpart C of 40 CFR part 261, or (2) Applying knowledge of the hazard characteristic of the waste in light of the materials or process used.
Ignitability (40 CFR 261.21) - No, the MSDSs for steel shot and structural steel show no evidence of iginitability.
Corrosivity (40 CFR 261.22) - No, the MSDSs for steel shot and structural steel show no evidence of corrosivity.
Reactivity (40 CFR 261.23) - No, the MSDSs for steel shot and structural steel show no evidence of reactivity.
Toxicity (40 CFR 261.24) - No, the MSDSs for steel shot and structural steel shows the presence of potential tixic metals. The shot blast dust has been tested for TCLP metals and found not hazardous.
5) Is this a hazardous waste mixture(see40 CFR 261.3(a)(iii) and (iv))?
No the material is not mixed with hazardous waste.
6) Is this derived from a hazardous waste(see 40 CFR 261.3(c) and (d))?
No, the material is dust collected from steel shot blasting.
Hope this helps you characterize this waste.
