Addendum
 
 
 
The following communication, received on 24 Se ptember 2007, is being circulated at the 
request of the Delegation of the United States . 
 
_______________  
 
 Amitraz, Atrazine, Ethephon, Ferbam, Lindane, Propachlor, and Simazine; Tolerance Actions
 
 By means of this regulation:  
Tolerances are established for the combined resi dues of the herbicide simazine (2-chloro-4,6-
bis(ethylamino)-s-triazine) and its two chlorinate d degradates (2-amino-4-chloro-6-ethylamino-s-
triazine and 2,4-diamino-6-chloro-s-triazine), the total residue to be measured in or on the following 
food commodities (in ppm): Almond at 0.25; Almond, hu lls at 0.25; Apple at 0.20; Avocado at 0.20; 
Blackberry at 0.20; Blueberry at 0.20; Cattle, meat at  0.03; Cattle, meat byproducts at 0.03; Cherry at 
0.25; Corn, field, forage at 0.20; Corn, field, grain at 0.20; Corn, field, stover at 0.25; Corn, pop, grain 
at 0.20; Corn, pop, stover at 0.25; Corn, sweet, forage at 0.20; Corn, sweet, kern el plus cob with husks 
removed at 0.25; Corn, sweet, stover at 0.25; Cranberry at 0.25; Currant at 0.25; Egg at 0.03; Goat, meat at 0.03; Goat, meat byproducts at 0.03; Grape at 0.20; Grapefruit at 0.25; Hazelnut at 0.20; Horse, meat at 0.03; Horse, meat byproducts at 0.03; Lemon at 0.25; Loganberry at 0.20; Milk at 0.03; Nut, macadamia at 0.25; Olive at 0.20; Orange at 0.25; Peach at 0.20; Pear at 0.25; Pecan at 
0.20; Plum at 0.20; Raspberry at 0.20; Sheep, meat at 0.03; Sheep, meat byproducts at 0.03; 
Strawberry at 0.25; and Walnut at 0.2.  
In addition, EPA is revising the tolerance term inology from filbert to hazelnut.  The reason for 
taking this action is because such action has no pr actical impact on the use of or exposure to the 
pesticide active ingredient, simazine, in or on that  commodity and is made such that the tolerance 
terminology will conform to current Agency practice.  
This regulation is effective 19 September 2007.  Objections and requests for hearings must be 
received on or before 19 November 2007, and ma y be identified by docket number EPA-HQ-OPP-
2007-0187.

This action is subsequent to a notice published in the Federal Register 13 June 2007, in which 
the Agency announced receipt of a pesticide petiti on proposing changes to existing tolerances for G/SPS/N/USA/1617/Add.1

  residues of simazine when used on the above co mmodities.  One comment was received by EPA from 
a member of the US Geological Survey, US Department of the Interior, who inquired whether the source of simazine, such as a contaminant of atr azine, could affect the Agency's proposed tolerance 
determinations for simazine.  
Agency response is as follows:  Combined simazine residues of concern (simazine and its two 
chlorinated degradates) detectable on food commod ities are regulated by tolerances established.  
These two chlorinated degradates of simazine are al so regulated as combined atrazine residues of 
concern.  The selection of an individual tolera nce level by EPA is base d on available crop field 
residue studies designed to produce the maximum residues under the existing or proposed product 
label. Generally, the level selecte d for a tolerance is a value slightly above the maximum residue 
found in such studies, provided that the tolerance is  safe.  In addition, for a food-use pesticide to be 
sold and distributed for domestic use in the Unit ed States, the pesticide must not only have 
appropriate tolerances under the FFDCA, but also must be registered.  Under federal law, residues on 
food shall not render the food adulterated so long as it is shown to the satisfaction of the US Food and 
Drug Administration that the residue is present as the result of an application or use of the pesticide at 
a time and in a manner that was lawful, and that the residue does not exceed the level that was authorized at the time of the application or use to be present on the food under a tolerance or 
exemption from a tolerance. In establishing, modify ing, leaving in effect, or revoking a tolerance or 
exemption for a pesticide chemical residue, the Ag ency considers, among other relevant factors, 
available information such as aggregate human exposur e levels to the pesticide residue.  The tolerance 
actions finalized herein for simazine are based on the available data which EPA has reviewed during 
the simazine RED process, and which the Agency has determined meet the required standard, are 
safe, and that there is a reasonable certainty (w ith appropriate mitigation)  that no harm to any 
population subgroup will result from aggregate expos ure.  However, EPA may propose to revoke 
tolerances for residues of a pesticid e when the Agency has determined  that the existing tolerances do 
not meet requirements federal law.  Any data on pot ential contamination of atrazine with detectable 
levels of simazine will be considered by the Agency  and appropriate tolerance actions, if needed, will 
be proposed for public comment.
