                        Date Issued:  April 16, 1996
                        Date of Expiration:  July 21, 1996
                        Report due: January 21, 1997
                        File symbol: 96-NY-05

The Environmental Protection Agency hereby grants a specific exemption
under the provisions of section 18 of the Federal Insecticide, Fungicide
and Rodenticide Act, as amended, to the New York State Department of
Environmental Conservation (NYSDEC) for the use of desmedipham, formulated
as Betanex (EPA Reg. No. 45639-86), to control broadleaf weeds in New York
State.  This specific exemption is subject to the following conditions and

1.   The New York State Department of Environmental Conservation is
responsible for ensuring that all provisions of this specific exemption are
met. It is also responsible for providing information in accordance with 40
CFR 166.32. This information must be submitted to EPA Headquarters and the
EPA Regional Office.

2.   A maximum of three ground broadcast or band applications per season is
requested. The first application at 0.25 lb ai/A will occur when red beets
have 2 leaves, followed by 0.25 to O.38 and 0.25 to 0.50 lb ai/A at the 4-
and 5-leaf stages, respectively, on 2,000 acres in Genesee, Livingston,
Ontario, and Orleans counties in New York.

3.   Desmedipham is classified as a Group "E" carcinogen (no evidence of
carcinogenicity). The total residues for the use of desmedipham on red
beets are not expected to exceed 0.2 ppm in red beet roots and 15 ppm in
red beet tops. Secondary residues in meat, milk, poultry, and eggs are not
anticipated. Analytical methodology and reference standards are available.

4.   A determination as to whether the proposed work clothing and personal
protective equipment (PPE) appearing on the label were in compliance with
the Worker Protection standards (WPS) could not be made since acute data
for this formulation was not provided. Handlers of desmedipham will be
required to wear a minimum amount of personal protective equipment such as
long-sleeved shirts, long pants, protective eyewear, chemical resistant
gloves and shoes plus socks. All future requests for this use must provide
a copy of the EPA stamped approved label which contains the WPS
precautionary labeling requirements.

5.   This proposed use under an emergency exemption presents minimal or no
risk to nontarget organisms and endangered species provided the label
directions/precautions are followed.

6.   The label for this emergency exemption must state the proposed use
rates and must state that the herbicide may only be applied by ground
equipment and existing label directions followed.

7.  A report summarizing the results of this program must be submitted to
EPA Headquarters and the EPA Regional Office by January 21, 1997, or prior
to requesting this use again under section 18, whichever is sooner.

8.  This specific exemption expires on July 21, 1996.

9.  Any future correspondence in Connection with this exemption should
refer to file symbol 96-NY-05.

10.  Although this is the first year this use has been requested, you are
advised that a decision regarding any future requests for this use will be
dependent, in part, on the progress made toward securing the registration
of this use of desmedipham on red beets.  Any future requests for this use
must discuss, in detail, the progress toward section 3 registration since
this last exemption was authorized.
