The following communication, received on 7 Augus t 2007, is being circulated at the request 
of the Delegation of the United States .

 Bromoxynil, Diclofop-methyl, Dicofol, Diquat, Etridiazole, et al.; Tolerance Actions
 
 By means of this rule:  
EPA is revoking the tolerance for "flax, straw".  Also, EPA is removing the commodity 
tolerances for residues of bromoxynil in or on "cor n, stover" which was previously termed corn, 
fodder (dry) in the RED; "corn, fodder (green)" ; and "corn, grain" because these tolerances are no 
longer needed since their uses are covered by the ex isting tolerances for corn, field, stover and corn, 
grain, field.  Further, EPA is increasing the tolera nce on "corn, field, stover" from 0.1 ppm to 0.2 ppm 
and establishing a tolerance for residues of bromoxyn il in or on "corn, pop, stover" at 0.2 ppm. 
 EPA is revising the commodity tolerance "alfalfa , seedling" at 0.1 ppm to "alfalfa, forage", 
and "alfalfa, hay" and maintaining the tolerance on alfalfa, forage at 0.1 ppm, while increasing the 
tolerance on alfalfa, hay to 0.5 ppm. 
 
EPA is revising the commodity terminologies "canarygrass, annual, seed" and "canarygrass, 
annual, hay" (formerly grass, canary, annual, straw) to "grass, forage" and "grass, hay", respectively, 
and increasing each of their tolerances from 0.1 ppm to 3.0 ppm. 
 EPA is increasing the tolerances for residues of bromoxynil in or on "barley, straw" from 0.1 
ppm to 4.0 ppm, and "oat, straw" from 0.1 ppm to 4.0 ppm. 
 EPA is increasing the tolerances for residues of  bromoxynil in or on "rye, forage" from 0.1 
ppm to 1.0 ppm; "rye, straw" from 0.1 ppm to 2.0 ppm; "wheat, forage" from 0.1 ppm to 1.0 ppm; and "wheat, straw" from 0.1 ppm to 2.0 ppm. 
 
EPA is increasing the tolerance for residues of  bromoxynil in or on "oat, forage" from 0.1 
ppm to 0.3 ppm. 
 EPA is increasing the tolerances for residues of bromoxynil in or on "sorghum, forage" from 
0.1 ppm to 0.5 ppm and revising the commodity terminology to "sorghum, grain, forage", and 
"sorghum, grain, stover" from 0.1 ppm to 0.2 ppm.  The Agency determined that the increased G/SPS/N/USA/952/Add.1 
Page 2  
 
  tolerances are safe; i.e., there is a reasonable certainty that no harm will result from aggregate 
exposure to the pesticide chemical residue. 
 EPA is decreasing the tolerances from 0.1 ppm to 0.05 ppm, for the following:  "barley, grain" 
"oat, grain", "rye, grain", "sorghum, grain", "wheat, gr ain", and "corn, grain, field", and also revising 
the terminolgy for "corn, grain, field" to read "corn, field, grain".  Also, EPA is establishing a 
tolerance for residues of bromoxynil in or on "corn, pop, grain" at 0.05 ppm. 
 EPA is establishing a tolerance for residues of br omoxynil in or on "grain, aspirated fractions" 
at 0.3 ppm. 
 
EPA is establishing tolerances for residues of bromoxynil in or on "barley, hay" at 9.0 ppm, 
"oat, hay" at 9.0 ppm, and "wheat, hay" at 4.0 ppm. 
 EPA is establishing a tolerance for "corn, field, forage" at 0.3 ppm. 
 
EPA is revising commodity terminology in 40 CFR 180.324 to conform to current Agency 
practice as follows: "mint hay" to "peppermint, hay" and "spearmint, hay". 
 This regulation is effective 30 October 2007.  Objections and requests for hearings must be 
received on or before 1 October 2007, and may be identified by docket number EPA-HQ-OPP-2004-
0154.

This action is subsequent to a notice published in the Federa l Register 4 August 2004, in 
which the Agency announced propo sed changes to tolerances for bromoxynil, among other pesticide 
agents.  One comment was received in regards to bromoxynil from China.  After the public comment 
period extension had ended on 18 October 2004, EPA received comment from China, forwarded by 
the US Department of Commerce's National In stitute of Standards and Technology, on 
3 November 2004.  China asked for information concerning Good Agricultural Practice (GAP) basis 
data for the use of bromoxynil on garlic and onion.  
The Agency’s response is as follows:  the Agency proposed no action on the existing 
tolerances in 40 CFR 180.324 for brom oxynil on garlic or onion, dry bulb. Information on study data 
which support the bromoxynil RED are available in th e OPP public docket for the proposed rule of 4 
August 2004, and on the reregi stration status website at 
http://www.epa.gov/pesticides/reregistration/status.htm
.  The crop field trial references for garlic are 
MRIDs 42331002 and 42540602, and for onion, dr y bulb are MRIDs 42350701 and 42747601.  The 
bromoxynil residues of concern on garlic and oni on, dry bulb were below the limit of quantitation 
(LOQ) of 0.02 parts per million (ppm), which suppor t their current tolerance levels at 0.1 ppm.
