Codes

Origin

i

The waste stream is recurrent: it was generated on-site from a production process, a service activity, or a routine cleanup (including off-specification or spent chemicals).

ii

The waste stream is non-recurrent: it is the result of a spill cleanup, equipment decommissioning, or other remedial cleanup activity.

iii

The waste stream is a residual from managing a recurrent non-dangerous waste.

iv

The waste stream is a storage/transfer: it was received from off-site and was not treated, recycled, or disposed on-site before being shipped off-site. It is considered non-recurrent because the waste comes from an off-site generator.

v

The waste stream is a residual from the management of a existing recurrent dangerous waste.
