3. SUMMARY OF REGULATORY POSITION AND RATIONALE
The Environmental Protection Agency (EPA) is proposing to
revoke the exemption from the requirement of a tolerance and
the food additive regulations for carbon tetrachloride, carbon
disulfide, ethylene dichloride, and chloroform. The tolerance
exemptions and food additive regulations are for the use of these
chemicals as grain fumigants.
This action is being taken because all products containing
CCI4, CD, EDC, or chloroform as an active ingredient for use as a
grain fumigant have been cancelled either voluntarily by the
registrants or by administrative action.
The data presently available to the Agency indicate that
carbon disulfide, ethylene dichloride, and chloroform are not
persistent and the,re is no anticipation of significant residues
resulting from the,last legal application of these chemicals, on or
before June 30, 1986. There is no need to establish action
levels to replace the existing tolerance exemptions upon their
revocat ion.
These limited data also indicate the presence of CCI4
residues in or on raw grain, intermediate grain products, and
ready-to-eat grain products. Although these data suggest that
residues of carbon tetrachloride are decreasing with time, it
would be difficult to utilize these data to establish tolerances
or action levels to replace the current tolerance exemption for
CCI4 upon its revocation. It is doubtful that the presence of
low levels of residues of this pesticide for this short-term period
would pose a risk to the public health.
EPA has discussed the appropriateness of action levels with
the Food and Drug Administration (FDA). They agree that action
levels should not be established and that FDA will not take en-
forcement action if residues are detected in grain or grain-based
consumer products after the exemptions are removed if it appears
such residues resulted from the legal use of the fumigants on or
before June 30, 1986. FDA has notifified the Agency in writing
of this position.
