If applicable, name of local government involved:    
2. Agency responsible:  Environmental Protection Agency (EPA)

deposited with the WTO; ICS numbers should be provided in addition, where 
applicable):  Cattle

5. Title, language and number of pages of the notified document:  PROPOSED RULE.  
Methamidophos, Oxydemeton-methyl, Profenofos , and Trichlorfon; Proposed Tolerance 
Actions (available in English, 9 pages) 
6. Description of content:  There are no active registrations  for the use of the insecticide 
trichlorfon for cattle commodities in the United States. However, trichlorfon is used as a 
dermal pour-on application on cattle for import purposes.  Based on cattle metabolism data 
from dermal application of trichlorfon which showed residues of trichlorfon as high as 0.2 
ppm in muscle and less than 0.5 ppm in fat, EPA is proposing to increase the tolerances on 
cattle, meat to 0.2 ppm and cattle, fat to 0. 5 ppm.  The Agency determined that the 
increased tolerances are safe; i.e., there is a reasonable certainty that no harm will result 
from aggregate exposure to the pesticide chemi cal residue.  Dichlorvos is a degradate of 
trichlorfon.  However, non-detectable dich lorvos residues in livestock commodities are 
expected as a result of trichlorfon use, and dichlorvos was not a significant metabolite in 
the trichlorfon dermal metabolism data.  Ther efore, dietary (food) exposure to dichlorvos 
residues resulting from use of trichlorfon is c onsidered by the Agency to be negligible.
