Frequent Questions

Who must sign the generator certification on the hazardous waste manifest? Does this person have any personal liability for the hazardous waste?

The hazardous waste manifest must be signed by the generator, but does not specify who must sign the certification if the generator is not an individual. The regulations define a generator as any person, by site, whose act or process produces hazardous waste, or whose act first causes a hazardous waste to become subject to regulation. The term person includes corporations, partnerships, and other legal entities for which some individual must sign the certification. EPA did not intend this requirement to impose personal liability on the individual who actually signs the certification (51 FR 35190, 35192; October 1, 1986).
