REVISION CHECKLIST 51

Revision Checklist 51 continues to be withheld.  Due to the settlement agreement reached on the litigation surrounding the September 1, 1988 (53 FR 33938) final rule, EPA will be promulgating amendments to this rule in the near future.  States are strongly encouraged not to adopt the provisions addressed by this final rule until these amendments have been promulgated.  Revision Checklist 51 may be moved to a later cluster due to the delay in issuing this checklist caused by the litigation and the resulting settlement agreement.
