      Attached you will find guidance  on  conducting  RCRA Facility
 Assessments (RFAs).  This document  replaces  the draft guidance
 (then called "PA/SI" guidance) which  was distributed in August,
 1985.   The guidance in this final document does not fundamentally
 alter the scope or approach to conducting RFAs  that was outlined
 in  the draft document.  Most revisions have  been made to clarify
 or  strengthen certain features of the guidance  to reflect what
.has been  learned from experience with conducting RFAs over the
 past  year.  Some revisions have also  been made  to reflect new
 policy developments associated with  implementing the RCRA corrective
 action program.

      I wish to make clear several important points  which have
 been  raised by Regions and others regarding  RFAs.   The RFA is
 meant to  provide the basis for decisions regarding  the necessary
 follow-on steps in implementing corrective action at facilities.
 VThile  it  is important to do a thorough RFA,  the approach and
 scope  of  an RFA will vary according  to site  specific conditions.
 Many  of the suggested steps or investigations  outlined  in the
 guidance  will be unnecessary at a given  facility.   RFA decisions
 will  often require applying professional judgment to the infor-
 mation collected during the RFA.

      It should be understood that it  will often be  necessary
 to  prioritize the releases and/or units  which will  be examined
 as  part of an RFA.  Certain releases  or  units at a  facility
 which  are of relatively lower priority may be  addressed, as
 appropriate, as part of a compliance  schedule in the order or
 permit, by requiring owner/operators  to  perform preliminary,
 RFA-type  investigations.

      In terms of the scope of RFA investigations, highest priority
 should be on assessing the discernible solid waste  management
 units at  the facility.  It may be appropriate  in some cases to
 assign a  relatively lower priority  to certain  solid waste management
 units  at  a facility, such as a solid  waste management unit which

cannot be located without substantial samplincj or other invest-
igations.  Likewise, releases or areas of facilities which are
not solid waste management units, but which are nevertheless
potentially subject to corrective action under RCRA  [e.g., §3008(h)]
or other authorities, should also be considered to be of relatively
lower priority in conducting RFAs.  A discussion of these other
types of releases, and how they may be addressed, is presented
below.

     Some guestions have been raised regarding the definition of
the term "solid waste management unit", which is relevant to
determining which units at a facility should be assessed in an
RFA.  The Final Codification Rule (July 15, 1985) identified the
types of discernible units which are considered solid waste
management units to include landfills, surface impoundments,
waste piles, land treatment units, incinerators, tanks, container
storage units, injection wells and other physical, chemical and
biological treatment units.  In addition, the Agency has inter-
preted the term to apply to areas associated with production
processes at facilities which have become contaminated as a
result of routine, systematic and deliberate releases of wastes
or constituents (a product may become a waste if it is discarded
or abandoned).  An example of this type of solid waste management
unit would be a wood preservative "kickback" area, where drippage
of preservative fluids onto soils from pressure-treated wood
is allowed to occur over time.

     Several Regions have reguested clarification regarding the
application of the concept of "solid waste management unit" to
other contaminated areas at facilities, such as one-time spills,
leakage from product storage, and releases from production areas
that are not routine, systematic and deliberate.  Such releases
are not considered to be solid waste management units.  As explained
in the Final Codification Rule, spills of wastes or constituents
are considered subject to §3004(u) corrective action only if the
spill occurred from a solid waste management unit.  A spill which
did not occur from a discernible solid waste management unit is
not of itself a solid waste management unit.  Likewise, leakage
from product storage and other types of releases associated
with production processes would not be considered solid waste
management units, unless those releases were routine, systematic
and deliberate.

     Although of relatively lower priority in conducting RFAs,
certain releases at facilities which are not related to solid waste
management units can be addressed using §3008 (h) or other enforce-
ment authorities.  In situations where an enforcement action has
been initiated at a facility to address releases that are not
related to solid waste management units, and where a permit is
subseguently issued to the facility, those actions can be continued
under the permit, under the authority of RCRA §3005(c)(3).
Likewise, at some facilities, investigators may have reason to
believe that an area that is not a solid waste management unit
is likely to be causing or have caused serious environmental
problems.  In such cases, compliance schedules may be written in
permits (under §3005(c)(3) authority) or orders to provide for

preliminary RFA-type  investigations by owner/operators  to  address
such areas.   If  releases.are subsequently identified which  require
further investigation or  action,  the permit or order can be modified
to provide for  necessary  owner/operator actions.

guidance, or  other  RFA-related issues,  please contact  Dave  Fagan
