      For the last four years we have had  a policy which requires
the  Regions to conduct formal biennial evaluations of NPL sites.
This was originally established because of a  concern that some
NPL  sites were being overlooked and could have  conditions which
posed immediate threats to health or the  environment.  We have
now  completed two complete cycles of the  evaluations.  During the
last one no new or unexpected concerns were identified.  Conse-
quently,  we have decided that a mandatory evaluation policy is no
longer necessary, though the Regions are  still  responsible for
having a process in place which is fully  protective.   The
attached directive revises the current policy.

      Please let me know if you have any questions.

 PURPOSE
       The purpose of this memorandum  is  to  revise the requirement
  for  biennial reviews of possible threats posed by National
  Priorities List (NPL) sites.

  BACKGROUND

       OSWER Directive 9200.2-03 established a requirement that
  Regions evaluate each NPL site at  least once every two years to
  make sure that there is no immediate threat to public health or
  the  environment.  This step was taken to eliminate the possibili-
  ty that potentially serious problems at sites with no active
  response were being overlooked.  The Regions have now been
  through two complete cycles of the evaluation process.  During
  the  last one, no new, unexpected concerns  or threats were identi-
  fied.
                                                       Recycled/Recyclable
                                                       Printed with Soy/Canola Ink on paper that
                                                       contains at least 50% recycled fiber

OBJECTIVE

     To reduce work not having a significant impact while contin-
uing to protect the public and the environment from unreasonable
risks posed by NPL sites.

IMPLEMENTATION

     Effective January 1, 1994, Regions no longer have to conduct
biennial evaluations of every NPL site.  Regions are still
responsible for seeing that no NPL site deteriorates to the point
that an immediate threat is posed, and promptly responding if a
problem is identified.  This will require good program coordi-
nation of the kind that the Superfund Accelerated Cleanup Model
(SACM) approach is intended to provide.  It is desirable that a
routine part of every Region's efforts, through its Regional
Decision Team or other appropriate mechanism, should be some
periodic review of all NPL sites to determine if response priori-
ties are correct and to see if there are opportunities for early
action.  The requirement remains that each newly proposed NPL
site receive a documented review and assessment within three
months of the date of proposal.
