Lindane (Isotox) - Proposing to Decline Special Review 4/94

April 8, 1994

  SUBJECT:  Reregistration Notification Network

       TO:  Users of the RNN

     FROM:  Dr. Nancy N. Ragsdale
            Director, NAPIAP

  Enclosed is the latest notice of the Reregistration Notification Network
  (RNN) dated April 8, 1994.  This notification contains an extensive list of
  residue tolerances potentially affected by the new interpretation of the
  Delaney Clause.  The registered uses causing these residues may eventually
  be canceled.  We'll keep you informed of any changes in or the
  implementation of this list.

The intent of this network is to inform interested parties of recent or
impending pesticide use cancellations, tolerance revocations, and other items
of agricultural interest.  To the best of our knowledge, the uses mentioned
here, unless otherwise indicated, will not appear on any label registered by
the USEPA after those uses are canceled.  We recommend that you express any
concerns or questions you have to the contact mentioned below or to your
NAPIAP State Liaison Representative.  If you wish to contact us at USDA, our
phone number is (301) 504-8846, and our fax number is (301) 504-8063.

lindane   The USEPA has proposed to not initiate a Special Review on the
          insecticide, lindane.  The USEPA notified registrants of the
          possibility of a new Special Review on lindane in 1985 based on a
          study which showed irreversible kidney effects in male rats.  They
          have determined that the kidney effects observed are specific to
          male rats and are not relevant to humans.  This is not an
          indication that lindane has been cleared for reregistration; its
          usage is likely to be sharply curtailed once its reregistration
          review is complete.  Written comments on this notice with reference
          to OPP-30000/10H should be sent to the Public Response Branch of
          EPA by 5/17/94.
