     State programs with delistlng mechanisms may receive interim authorization
if their delisting mechanisms are substantially equivalent to EPA's.  To meet
the substantially equivalent test, States' delisting methodology must be consis-
tent with their methodology for listing.  States' delisting mechanisms must not
interfere with the "nearly identical" universe of waste between the States and
EPA.  Where a State's delisting activities cause its universe to be no longer
nearly identical with EPA's, EPA could withdraw that State's interim authorisa-
tion.  The Memorandum of Agreement must make this possibility of withdrawal of
authorization clear to  the State, and must contain a promise that the State
will keep EPA informed  of any State delisting activity.

     The memo discusses the interaction between the States' delisting mechanism
and the Federal program and includes an itemlzation of the necessary showings
persons requesting delisting of waste must make in their petition to EPA.

     Can a State with an authorized hazardous .waste management
program be allowed to exempt  ("delist") hazardous waste  from
individual sites?

DISCUSSION:

     EPA has provided certain standards and procedures for
"delisting1* waste from a particular generating  facility  or storage,
treatment, or disposal facility at which a hazardous waste is
generated (see 40 CPU 260.20 and 260.22, 45 FR  33076, and preamble
discussion at 45 FR 33116).  Persons seeking such a delisting
action may petition the Administrator of EPA for an amendment to
the Federal regulations which would provide the exemption.  In the
petition, the^person must show that the waste is fundamentally
               that listed by demonstrating, as appropriate, that th
waste
     (1)  eiibit the characteristic of ignitability,
          corrosivity, reactivity, or toxicity,
     (2)  raa
-------
           (3)   contain the  hazardous  constituent of Appendix VTII
                of 40  CPR  261  (45 PR 33312)  for which it was listed,
                or, if the waste does  contain those constituents,
                show that  consideration of other factors argue against
                th*>waste  being considered a hazardous waste (see
                40---"CFR 261.11(a)(3), 45 PR 33121).  This decision
                is based on  consideration of any of approximately ten
                factors and  is a discretionary one.

        When a  State  program has been found to be substantially
   equivalent; to the  Federal program, it receives interim    x
   authorization to operate in lieu of the  Federal program; i.e.,
   Federal requirements generally no  longer apply, and the "requiremen,
   of this subtitle1*  which  are enforced under section 3008 of the
   Act are those of the State program'approved under section 3006.
   Therefore, action  by SPA to  i .ist a. waste from a particular
   generating facility (or  storage, treatment, or disposal facility
   which generates hazardous waste) in a State with interim authorization
   would not affect the State requirements  unless the State took a
   similar action.

        Som* concern  exists regarding the potential incompatibility
   inherent, in  allowing, one State to  delist., whereas another States
   may desire not to  delist.  This problem  is not unique to the
   issue of d all sting,  since the latter State program- may be viewed
   as a "more stringent"  one (because it regulates more wastes) and
   is acceptable under section 3009 of RCRA.  (See the preamble to
   40 CPR Part  123, Subparts 3 and F, 45 PR 33385.)

        The. question here is whether  a State program with interim
   authorization can  provide a delis-ting mechanism.  If so, what shape
   and form must that mechanism take  if EPA is to authorize the State-
   program as "substantially equivalent" to the Federal program?

        In the regulations  under 40 CFR Part. 123, EPA is silent on
  'the issue of State dells-ting mechanisms.  A State without such
   a mechanism is not precluded from  receiving interim authorization.
   'The universe of wastes controlled  by such a State would be subject
   to change onvtipthrough regulatory  or statutory change.
        For interia. authorization, EPA requires the States to
   control a univisrs* of hazardous waste generated,, treated/
   stored, and disposed of in the State which is nearly identical
   to that which would be controlled by the Federal program under
   40 CPR Part 261 (see 40 CPR 123.128(a), 45 PR 33481).  A State can
   dascns-crata that iis pzrcgrs^; cca-ca.^3 a dalia-iing prevision which,
   nevertheless, leaves the State universe nearly identical to EPA's.
__  On the other hand, if the State's delisting mechanism lacked explicit:


-------
 standards  and  procedures  analogous  to  those  included  in  SPA's
 delisting  mechanism,  it would be difficult for  EPA  to assure
 that  the State was providing the proper  control of  wastes.

      It is possible- that,  a  State, as a result of  its  delisting ,
 may deer ease-- its universe of wastes such that its coverage is  no
 longer nearly  identical to  the Federal universe.  For example, a
 question has arisen as to what would happen  if  an interim authorized
 State abused its discretion in delisting wastes from  individual
 sites, but EPA, operating the Federal  program in  one  or  more
 States into which those wastes were imported, refused to delist
 the wastes from those sites.  This would clearly  be a situation
 where the  State would be  subject to withdrawal  of SPA's  author izatio:
 for failure to exercise control over activities required, to be
 regulated  (40  CFR 123.136 and 40. CFR 123. 14 (a) (2)
DECISION;  State programs with delisting mechanisms may receive
Ixiterim~~authorization provided those delisting mechanisms are
substantially equivalent to SPA's.  In order to be considered
substantially equivalent, the State must demonstrate  that the
delisting methodology is consistent with its methodology for
listing.  The Memorandum of Agreement must contain a  provision
that the State will keep EPA fully informed of any State deliating
activities and should make clear the possibility of withdrawal
of authorization in the event that, due to delistlngs, the  State's
universe of wastes is no longer nearly identical to EPA1 3.
