that you include your name and other contact information in the body of 
your comment and with any disk or CD ROM you submit. If EPA cannot read 
your comment due to technical difficulties and cannot contact you for 
clarification, EPA may not be able to consider your comment. Electronic 
files should avoid the use of special characters, any form of 
encryption, and be free of any defects or viruses. For additional

SUPPLEMENTARY INFORMATION:

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).

[[Page 18743]]

     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 
affected. The North American Industrial Classification System (NAICS) 
codes have been provided to assist you and others in determining 
whether this action might apply to certain entities. If you have any 
questions regarding the applicability of this action to a particular 
entity, consult the person listed under FOR FURTHER INFORMATION 
CONTACT.

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 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 
reproduced.
    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.
    viii. Make sure to submit your comments by the comment period 
deadline identified.

II. What Action is the Agency Taking?

    EPA is printing a summary of each 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 these pesticide petitions 
contain 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 
of these pesticide petitions. Additional data may be needed before EPA 
rules on these pesticide petitions.
    Pursuant to 40 CFR 180.7(f), a summary of each petition included in 
this notice, prepared by the petitioner along with a description of the 
analytical method available for the detection and measurement of the 
pesticide chemical residues is available on EPA's Electronic Docket at 
http://www.regulations.gov. To locate this information on the home page 

of EPA's Electronic Docket, select ``Quick Search'' and type the OPP 
docket ID number. Once the search has located the docket, clicking on 
the ``Docket ID'' will bring up a list of all documents in the docket 
for the pesticide including the petition summary.

New Tolerance

    (PPs) 5E6965, 5E6966, 5E6967. Interregional Project Number 4, 681 
Highway 1 South, North Brunswick, NJ 08902-3390, proposes to establish 
tolerances for residues of the insecticide diflubenzuron, (N-[[(4-
chlorophenyl)amino]carbonyl]-2,6-difluorobenzamide) and metabolites 
convertible to p-chloroaniline expressed as diflubenzuron in or on the 
following food commodities:
     1. (PP) 5E6965 proposes to establish tolerances for barley, grain; 
oat, grain; and wheat, grain at 0.06 parts per million (ppm); barley, 
forage; oat, forage; and wheat, forage at 5.0 ppm; barley, hay; oat, 
hay; and wheat, hay at 2.0 ppm; barley, straw; oat, straw; and wheat, 
straw at 2.0 ppm; barley, aspirated barley fractions; oat, aspirated 
oat fractions, and wheat, aspirated wheat fractions at 3.0 ppm; and 
pummelo at 0.5 ppm.
     2. (PP) 5E6966 proposes to establish tolerances for brassica, 
leafy greens subgroup 5B; turnip at 8.0 ppm; eggplant at 1.0 ppm; and 
okra at 1.0 ppm.
    3. (PP) 5E6967 proposes to establish a tolerance for peanut at 0.2 
ppm.
    A practical analytical method for detecting and quantifying levels 
of diflubenzuron in or on food with a limit of detection that allows 
monitoring of the residue at or above the level set in the tolerance 
was used to determine residues in wheat and barley commodities.
    Residues of the individual analytes are detectable and quantifiable 
using three separate analytical methods. Residues of diflubenzuron are 
extracted from wheat and barley with dichloromethane and are purified 
with deactivated florisil. An aliquot of the extract is hydrolyzed with 
phosphoric acid and the diflubenzuron is partitioned into hexane. The 
resulting extract is derivatized in heptafluorobutyric anhydride 
(HFBA). Quantification of diflubenzuron is accompanied by gas 
chromatography using electron capture detection.
    The analytical method for quantitation of the 4-chlorophenylurea 
requires ethyl acetate extraction of the residue from the crop matrix. 
Column chromatography is utilized for clean-up of the extract 
immediately prior to derivitiation with HFBA. Derivatized extracts are 
analyzed by gas chromatography equipped with an electron capture 
detector.
    Analysis for the determination of PCA residues in wheat and barley 
matrices utilizes an internal standard method. Samples of matrix to be 
analyzed are fortified with an internal standard. Residues of 14C-PCA 
and the internal standard are subjected to acid and base hydrolysis. 
The final extract is passed through a florisil column for clean-up and 
derivatized with HFBA in hexane. An aliquot of the derivatized extract 
is analyzed by gas chromatography equipped with Mass Spectrometry 
detection. Recovery of PCA is determined from the combined peak areas 
for the two mass spectral ions obtained from the derivatized PCA 
relative to the response factor derived from the combined areas of the 
corresponding two mass spectral ions of the internal standard.
