The regulations require that persons who recover regulated refrigerants from salvaged items must themselves hold the appropriate certification for the type of equipment being recovered, or be directly supervised by someone who is properly certified. Persons who salvage or dismantle entire units of refrigeration equipment must register annually with the DNR (Form 4500-129), certifying that they are using approved equipment to recover any remaining refrigerants and that persons using this equipment are properly qualified. Refrigeration equipment salvagers may make arrangements for someone else to perform the refrigerant recovery, but still must register with DNR (unless that facility is already registered). The "subcontractor" must use approved recovery equipment operated by properly qualified operators, and records of recovery activities must be kept. A description of this arrangement must be included in the salvager's registration.
