     As  I have  indicated  in previous correspondence,  I  intend  to
issue later this summer a revised final version of the  "Procedures
for Planning and Implementing Off-site Response Actions"  (Off-site
•Policy, May 6,  1985).  At that time I intend to provide additional
guidance on determinations of ineligibility based upon  "other
environmental conditions" that affect the satisfactory operation
of the facility or that pose a significant  threat to  public
health, welfare or the environment.

     One of the key issues in interpretation of the policy
surrounds applying this standard to facilities in assessment
monitoring.  Section II.8.5. of the policy states in  part:

     "For facilities in assessment monitoring, the conditions
     which lead to required assessment monitoring, as well
     as resulting monitoring data, must be evaluated.

and

     "If a facility is in assessment monitoring, the  conditions
     which lead to assessment monitoring may constitute
     environmental conditions that adversely affect facility
     operations.  In such cases, Regions should assess  the
     conditions at the facility prior to using the facility for
     Superfund purposes",  (emphasis added).

     In applying this provision to facilities in your Region,  you
should use the following guidelines:

     *  Facilities which are in assessment monitoring should not
        automatically be deemed ineligible under the  off-site  policy,

                               -2-
     0  When a facility is required to begin assessment monitoring,
        the Waste Management Division Director should evaluate the
        data which lead to assessment monitoring and any other
        relevant information.

     0  Based on his evaluation, the Director should determine
        that the facility is ineligible if;

           there is a probable release to ground water, and
           the release is significant in that it will affect
           satisfactory operation of the facility (e.g. the
           release is from an active unit) or may pose a
           significant threat to public health and the environment.

     0  Where information available at the time a facility begins
        assessment does not support such a determination, the
        facility remains eligible.  However, the Director should
        continually reassess eligibility as more information becomes
        available through the assessment monitoring program.

     8  A determination of ineligibility may be made at any time
        prior to, during or subsequent to the assessment monitoring
        program.

     It is important to ensure smooth operation of the Superfund
program that this policy be applied fairly and uniformly.  I
urge you to be certain that any decisions of ineligibility are
made based upon careful consideration and that facilities are
promptly notified as discussed in my memorandum dated May 12,
1986.  If you have any questions about implementation of the
policy, please contact either Michael Kilpatrick (382-5324) or
Jackie Moya (382-3122) of the Office of Waste Programs
Enforcement.
