     MEMORANDUM

     SUBJECT:  Community Relations Requirements for Operable Units

     FROM:     William N. Hedeman, Jr^Y>JL
               Director, Office of EmergenrcyandReraedial Response

     TO:       Addressees

          This memorandum presents community relations requirements
     and guidance for operable units of remedial actions.  The first
     section discusses the concept of an "operable unit" as defined in
     the proposed revisions to the National Oil and Hazardous Substances
     Pollution Contingency Plan (NCP), providing an example of how
     remedial activities at a site can be divided into operable units.
     The second section of the memorandum presents guidance and require-
     ments.  This guidance for operable units does not require major
     changes in the planning and implementation of community relations
     programs for Superfund remedial actions.  All other community
     relations requirements remain unchanged.

     BACKGROUND

          The proposed revisions to the NCP (50 PR_ 29, February 12,
     1985, PP. 5862-5932) define an "operable unit" as "a discrete
     response measure that is consistent with a permanent remedy, but
     is not the permanent remedy in and of itself."  According to the
     preamble to the revised NCP,  the proposed change "reflects EPA's
     practice of dividing complex  response actions into operable
     units."  Operable units can be conducted as removal actions, even
     though they are parts of remedial responses at NPL sites.  Operable
     units are implemented prior to selection of a final remedial
     action, provided "such measures are cost effective and consistent
     with a permanent remedy" (Section 300.68(d)).

          In practice, an operable unit is a flexible concept, applicable
     to a wide range of construction measures that result in measurable
     public health or environmental improvements at a given site.
     Operable units are not limited to short-term actions;  the terra
     should not be equated with "initial remedial measure."  Instead,
     remedial response activities  can be divided into any number of

operable units, depending on the complexity of the problems
associated with the site.  Each operable unit, however, must by
itself serve to eliminate or mitigate a release or threat of a
release.  If more than one operable unit is conducted during
remedial activities at a site, each operable unit may require a
separate remedial investigation and feasibility study (RI/PS).
The need for a separate RI/PS for each operable unit, however, is
determined on a site-specific basis.

     An example of how response actions at a site can be divided
into operable units may help in understanding the operable units
concept.  Using a hypothetical remedial action, response activities
at this particular site are divided into three operable units.
The first operable unit involves the removal of drums and other
hazardous materials located on the surface of the site.  As the
second operable unit, waste oil lagoons are drained and contaminated
soil at the site is removed.  The third operable unit involves
activities to control groundwater contamination at the site; the
extent of the groundwater contamination plume is assessed, and
measures are taken to mitigate the contamination problem.  Because
each of these operable units involves separate response measures,
it is possible that two or more of the operable units could be
conducted concurrently.  For example, the operable unit involving
the removal of drums stored on site could be started at the same
time as the operable unit involving the removal of waste oils on
site.  If appropriate, both of these operable units could be
addressed in one RI/PS.

     As the background discussion above suggests, the term "operable
unit" has a specific technical meaning; however, the meaning is
not likely to be clear at first to citizens.  In public documents,
therefore, operable units can be referred to as "segments" of the
response action.

GUIDANCE ANDREQUIREMENTS

     The community relations requirements for operable units will
enable the public to have meaningful opportunity to comment on
all remedial measures before they are implemented.  Specific
requirements are expressed as answers to the questions below.

     1)  Is a three weekpublic comment period required for each
         operable unit?

         A three-week public comment period is required for each
         operable unit including removals, unless the operable
         unit is conducted as an emergency removal action.  The
         operable unit will be initiated after the three-week
         public comment period.

         If there has been a feasibility study explicitly addressing
         the operable unit, the basis for comment will be public
         review of the draft feasibility study report.  If'there
         has not been a feasibility study explicitly addressing
         the operable unit, a. public comment period is still
         required; the basis for public comment will be the work
         plan for the operable unit, or an agency-prepared summary of
         the work plan.

     2)  If the draft feasibility study report proposes dividing
         response activities at a site into more than one operable
         unit, must a separate public comment period be held for""
         each operable unit?

         For each draft feasibility study, only one public comment
         period is necessary, regardless of how many operable
         units are proposed as part of the recommended remedial
         alternative.  In effect, the comment periods for the
         operable units are combined; the public still has the
         opportunity to comment on each operable unit.  No matter
         how many feasibility studies are conducted during the
         remedial response, however, there must be a three-week
         public comment period on each draft feasibility study
         report.

     3)  Does a community relations plan have to be prepared for
         each operable unit?

         A community relations plan does not need to be prepared
         for each operable unit provided the plan covers all
         anticipated operable units.  The community relations
         plan prepared prior to beginning the initial RI/FS
         should be revised, however, if unanticipated operable
         units are implemented, or if unanticipated HI/PS activi-
         ties are initiated for subsequent operable units, during
         later stages in the response action.
