                                             DECEMBER  86

                    the owner/operator of an existing landfill unit which is
                    holding P006 waste, wants to remove all the waste frcrc the
                    landfill in order to stabilise it.  Once the waste is stabilized,
                    it will be put back in the same landfill and the landfill will
                    then be closed,  will this action Grange the status of the
                    landfi II £rom an existing unit to a replacement unit? If she
                    landfill was then considered a replacement unit, would it
                    have to fleet cidnijium technology requirements under §3004(u)
                    of BCRA before the stabilized waste is replaced?

                         A uedt is considered a replacement if it is taken out
                         of service and all or substantially, all waste is removed
                         from it, and then reused.  If the removal, stabilization,
                         and replacement of the waste is part of closure, and no new
                         waste is being added to the landfill/ then SPA does not consider
                         that the unit has been "reused".  Therefor*, the landfill would
                         retain its status as an existing unit and would not haw to
                         meet minimum technology standards prior to replacing the waste.
