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):  Wheat (grain, straw, forage, and hay)  and barley (grain, hay, and straw)  
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:  FINAL RULE .  Acetic 
acid, [(5-chloro-8-quinolinyl) oxy]-, 1-methyl hexyl ester (Cloquintocet-mexyl); Pesticide 
Tolerance (Available in English, 9 pages)  
6. Description of content:  EPA has reviewed the data and information submitted by the 
petitioner in support of the establishment of tolerances for the combined residues of cloquintocet-mexyl and its acid metabolite (5 -chloro-8-quinolinoxyacetic acid) in or on 
wheat (grain, straw, forage, and hay) and barley  (grain, hay, and straw) as required in the 
Federal Register of 22 June 2000 ( 65 FR 38757 ; FRL-6592-4). 
The residue data show that residues are not expected to exceed 0.01 ppm in barley grain 
(LOQ) and 0.05 ppm in barley hay and straw. The Agency will establish permanent tolerances for the combined residues of cloqui ntocet-mexyl (acetic acid, [(5-chloro-8-
quniolinyl)oxy]-, 1-methylhexyl ester)(CAS Re g. No. 99607-70-2) and its acid metabolite 
(5-chloro-8-quinlinoxyacetic acid), in/on ba rley (straw, hay and grain) at 0.1 ppm. 
 
The available data indicate that no revisions to  the current tolerance levels of 0.1 ppm on 
wheat, forage and wheat, hay are needed.   EPA does not agree that grounds exist to increa se the tolerance expressions for wheat forage 
and hay because residues of cloquintocet-mexyl will not exceed 0.1 ppm.  EPA established 
tolerances for the combined residues of pinoxaden in or on barley and wheat in the Federal Register on July 27, 2005 ( 70 FR 43313 ) (FRL-7725-5). Therefore, EPA is granting the 
petition to allow the use of the safener cloquint ocet-mexyl with pinoxaden in a 1:4 ratio of 
safener to active ingredient in or on wheat (gra in, straw, forage, and hay) and barley (grain, 
hay, and straw).  
7. Objective and rationale: [ X ] food safety,  [   ] animal health,  [ X ] plant protection, 
[ X ] protect humans from animal/plant pest or disease, [   ] protect territory from 
other damage from pests   G/SPS/N/USA/1188

 8. International standard, guideline or recommendation: 
[   ] Codex Alimentarius Commission,  [   ] World Organization for Animal Health 
(OIE), [   ] International Plant Protection Convention,  [   ] None 
If an international standard, guideline or recommendation exists, give the appropriate 
reference and briefly identify deviations:  There are no Codex tolerances established for 
cloquintocet mexyl. Australia has establis hed maximum residue limits (MRLs) for 
cloquintocet-mexyl on wheat and barley at 0.1 ppm.
