NOTIFICATION  
 
1. Member to Agreement notifying:  UNITED STATES  
If applicable, name of local government involved:    
2. Agency responsible:  Environmental Protection Agency (EPA) 
3. Products covered (provide tariff item number(s) as specified in national schedules 
deposited with the WTO; ICS numbers should be provided in addition, where applicable):  Sugarcane, rye grass, corn, macadamia nut, sorghum, wheat 
4. Regions or countries likely to be affected , to the extent relevant or practicable :  Any 
US trade partners  
5. Title, language and number of pages of the notified document:  PROPOSED RULE.

Tolerance Actions (available in English, 13 pages) 
6. Description of content:  By means of this rule and on the basis of available data, the 
Agency proposes the following ch anges to existing federal regulations for the pesticide 
atrazine: 
Currently, there is only one active registration fo r use of atrazine on perennial rye grass and 
that use is restricted. Becau se the label restricts grazing a nd cutting for feed, the Agency 
has determined that the tolerance on perennial rye grass is no longer needed and should be 
revoked. Therefore, EPA is proposing to revoke the tolerances for the combined residues of 
atrazine in or on rye grass, perennial at 15 ppm. 
Because EPA no longer considers sugarcane f odder and forage to be significant livestock 
feed items their tolerances are no longer needed and therefore should be revoked. Consequently, EPA is proposing to revoke the tolerances in for sugarcane, fodder and 
sugarcane, forage.  
EPA is proposing to decrease the tolerances on "c orn, pop, stover" to 0.5 ppm; "corn, 
fodder, field" to 0.5 ppm and to revise the commodity terminology to "corn, field, stover", and "corn, sweet, stover" to 2.0 ppm. 
EPA is proposing to decrease the tolerances fro m 0.25 to 0.20 ppm for "corn, sweet, kernel 
plus cob with husks removed" a nd "corn, grain" and revise the terminology to "corn, field, 
grain" and "corn, pop, grain". 
EPA is proposing to decrease the tolerance for combined residues of atrazine in or on "nut, 
macadamia" from 0.25 to 0.20 ppm. 
EPA proposes decreasing and revising the tolera nces for the combined residues of atrazine 
in or on "sorghum, grain" at 0.25 ppm to "sorghum, grain, grain" at 0.20 ppm and 
"sorghum, fodder" at 15 ppm to 0.50 ppm. G/SPS/N/USA/1620

  EPA is proposing to decrease the tolerance on sugarcane, cane from 0.25 to 0.20 ppm. 
EPA is proposing to decrease the tolerances on wheat, grain to 0.1 ppm and wheat, straw to 
0.5 ppm. 
EPA is proposing to revoke the duplicat e tolerance on wheat, straw and establish a 
tolerance on wheat, forage at 1.5 ppm. In add ition, based on field trial data that showed 
atrazine residues of concern as high as 1.11 ppm on wheat forage and adjusting for the 
difference in dry matter between hay and fo rage (88% vs. 25%), the Agency expects 
combined residues of about 3.9 ppm on wheat hay and therefore determined that a tolerance should be established on wheat hay at 5.0 ppm. Consequently, EPA is proposing 
to establish a tolerance on wheat, hay at 5.0 ppm.
