I. General Information

A. Does this Action Apply to Me?

    You may be potentially affected by this action if you are an 
agricultural producer, food manufacturer, or pesticide manufacturer. 
Potentially affected entities may include, but are not limited to:
     Crop production (NAICS code 111).
     Animal production (NAICS code 112).
     Food manufacturing (NAICS code 311).
     Pesticide manufacturing (NAICS code 32532).
    This listing is not intended to be exhaustive, but rather provides 
a guide for readers regarding entities likely to be affected by this 
action. Other types of entities not listed in this unit could also be

B. What Should I Consider as I Prepare My Comments for EPA?

     1. Submitting CBI. Do not submit this information to EPA through 
regulations.gov or e-mail. Clearly mark the part or all of the 
information that you claim to be CBI. For CBI information in a disk or 
CD ROM that you mail to EPA, mark the outside of the disk or CD ROM as 
CBI and then identify electronically within the disk or CD ROM the 
specific information that is claimed as CBI. In addition to one 
complete version of the comment that includes information claimed as 
CBI, a copy of the comment that does not contain the information 
claimed as CBI must be submitted for inclusion in the public docket. 
Information so marked will not be disclosed except in accordance with 
procedures set forth in 40 CFR part 2.
     2. Tips for preparing your comments. When submitting comments, 
remember to:
    i. Identify the document by docket ID number and other identifying 
information (subject heading, Federal Register date and page number).
    ii. Follow directions. The Agency may ask you to respond to 
specific questions or organize comments by referencing a Code of 
Federal Regulations (CFR) part or section number.
    iii. Explain why you agree or disagree; suggest alternatives and 
substitute language for your requested changes.
    iv. Describe any assumptions and provide any technical information 
and/or data that you used.
    v. If you estimate potential costs or burdens, explain how you 
arrived at your estimate in sufficient detail to allow for it to be 
    vi. Provide specific examples to illustrate your concerns and 
suggest alternatives.
    vii. Explain your views as clearly as possible, avoiding the use of 
profanity or personal threats.

II. What Action is the Agency Taking?

    EPA is printing a summary of a pesticide petition received under 
section 408 of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 
U.S.C. 346a, proposing the establishment or amendment of regulations in 
40 CFR part 180 for residues of pesticide chemicals in or on various 
food commodities. EPA has determined that this pesticide petition 
contains data or information regarding the elements set forth in FFDCA 
section 408(d)(2); however, EPA has not fully evaluated the sufficiency 
of the submitted data at this time or whether the data support granting

New Tolerance

    PP 4F6889. E. I. du Pont de Nemours & Company, Laurel Run Plaza, 
P.O. Box 80038, Wilmington, DE 19880-0038, proposes to establish a 
tolerance for residues of the herbicide thifensulfuron methyl (methyl-
yl)amino]carbonyl]amino]sulfonyl]-2-thiophene carboxylate) in or on 
grain sorghum (forage, grain, and stover); and rice (grain and straw) 
at 0.05 parts per million (ppm).
    Thifensulfuron methyl residues in grain sorghum (grain) were 
determined by an analytical method utilizing liquid chromatography/mass 
spectrometry/mass spectrometry (LC/MS/MS) analysis. The analytes were 
resolved by high pressure liquid chromatography (HPLC) and 
quantitatively analyzed by tandem mass spectrometric detection. The 
limit of quantitation (LOQ) was 0.05 ppm. Residues in rice commodities 
and in grain sorghum (forage and stover) were determined with an 
analytical method utilizing sample extraction by homogenization in a 

[[Page 40105]]

phosphate buffer solution. The extracts were cleaned up and 
concentrated by solid-phase extraction. Analysis was performed by 
reversed-phase HPLC and quantitatively analyzed by tandem mass 
spectrometric detection. The target LOQ was 0.05 ppm for these
