                          *•
           Me have received numerous inquiries regarding the applicability
      of the RSWA-imposed minimum technological requirementa for liners
      and leachate collection aystems at hatardoua waete landfllla,
      surface iepoundnent«f and vaate  pi lee*  Thia neaoraadm outlines
      the aoat or itice1 factors for determining the applicability of
      the •laiausi technological requirement a.  The guidance contained
      herein will be incorporated into an upcoming veraion of the
      Xeauthoriaation Statutory Interpretation (RSI) for the minimua
      technological requirementa*  Other important applicability
      iaauea, aueh aa definition of the ten •replacement unit**
      will be addreaeed in the RSI*
i/i

^          Aa you know* the nev vinimua technological requireaenta
CM     are contained in sections 3004(o) and 3015 of RCRA*  Among
^     other things, these sections require that (a) nev landfill and
£     aurface impoundment units and lateral expansions and replacementa
«»     of existing landfill and surface impoundment units must have
£     two or more liners and a leachate collection system above (in
^     the case of a landfill) and between the liners) and (b) new
«     interim status waste pile units and lateral expanaione and
12     replacements of existing interim status waste pile units
§     must meet the current regulations for new, permitted waste piles.
3t     RCRA Subtitle C permita issued after Sovember 8, 1984, must
e     include these provisions, and interim status facilitiea must
••     meet the requirements with respect to waste received after
H     Hay 8, 1985.
