Q

To determine hazardous waste, generators must answer the following questions:

A
  • Does the generator have knowledge that waste is hazardous under RCRA regulations?
  • Did a test define the material as RCRA waste (characteristic hazardous waste)?
  • Is the waste exempt from regulation as “hazardous” under RCRA rules?
  • Is the waste included on EPA’s hazardous waste list?
  • If hazardous or nonhazardous, what Federal, State, or local standards must be satisfied?

Q

Paint chip analysis should only be used to determine specific lead compound present if __________

A
  1. The total lead level is very low (<100 ppm), indicating that waste should not exceed the TC threshold.
  2. Total lead levels can be used in combination with total waste volume estimates to determine whether recycling for lead recovery is feasible.
