Subject:      Triple Rinsing of Containers

Summary:

     Empty containers are divided into two groups: those  which formerly con-
tained acutely hazardous wastes and all others.  For the  latter group,  there is
no specific requirement for rinsing; the regulation merely requires  that the
waste be removed in its normal manner, whether pouring, pumping, aspiring—and
that no more than 2.5 centimeters (or equivalent weight)  of residue  remain for
the container to be considered "empty."  However, for containers that  formerly
held acutely hazardous wastes, triple rinsing or its demonstrated equivalent is
required as per §261.7(b)(3).

   '  A suitable solvent for the hazardous material must be used according to
the regulation.  Such emptying, if done properly, does not constitute  treatment,
and thus a permit is not required.  However, whatever residue remains  in the
"empty" container is no longer considered to be a hazardous waste.

     RCRA is intended to be a State-operated program.  Therefore, where the
State has been given the authority by EPA, it is the State regulations  that
apply.  State rules may be more stringent than Federal rules; therefore, each
State where the rinsing process may be used must be contacted to determine its
position on empty containers.

and equipment appear to oe capaole  ot nieetin.3 this  roquiranent.

     Uhon we proposed  and then issued this regulation, we indicated
that  <»ucn enptyincj,  or triple rinsing,  did not constitute treatment,
and thus, a pormit  ig  not required.   Sinew the solvent night vary
according to tha former contents of the containers, a priori
approval  of a specific solvent/process  is not possible.  Your
equipment, if the correct solvent is  used, would accomplish the
triple  rinsing.  A3  stated in the regulations, whatever residue
remains in the "empty" container is no  longer considered to he a
hazardous waste.
