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).
     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 at the end of the pesticide petition 
summary of interest.

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 email. 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 
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.
    3. Environmental justice. EPA seeks to achieve environmental 
justice, the fair treatment and meaningful involvement of any group, 
including minority and/or low-income populations, in the development, 
implementation, and enforcement of environmental laws, regulations, and 
policies. To help address potential environmental justice issues, the 
Agency seeks information on any groups or segments of the population 
who, as a result of their location, cultural practices, or other 
factors, may have atypical or disproportionately high and adverse human 
health impacts or environmental effects from exposure to the pesticides 
discussed in this document, compared to the general population.

II. What action is the agency taking?

    EPA is announcing its receipt of several pesticide petitions filed 
under section 408 of the Federal Food, Drug, and Cosmetic Act (FFDCA), 
21 U.S.C. 346a, requesting the establishment or modification of 
regulations in 40 CFR part 174 or part 180 for residues of pesticide 
chemicals in or on various food commodities. The Agency is taking 
public comment on the requests before responding to the petitioners. 
EPA is not proposing any particular action at this time. EPA has 
determined that the pesticide petitions described in this document 
contain the data or information prescribed 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 the pesticide 
petitions. After considering the public comments, EPA intends to 
evaluate whether and what action may be warranted. Additional data may 
be needed before EPA can make a final determination on these pesticide 
petitions.
    Pursuant to 40 CFR 180.7(f), a summary of each of the petitions 
that are the subject of this document, prepared by the petitioner, is 
included in a docket EPA has created for each rulemaking. The docket 
for each of the petitions is available online at http://www.regulations.gov.
    As specified in FFDCA section 408(d)(3), (21 U.S.C. 346a(d)(3)), 
EPA is publishing notice of the petition so that the public has an 
opportunity to comment on this request for the establishment or 
modification of regulations for residues of pesticides in or on food 
commodities. Further information on the petition may be obtained 
through the petition summary referenced in this unit.

Cypermethrin is a pyrethroid insecticide consisting of three asymmetric 
carbon atoms, and therefore, 8 stereo-isomeric mixtures. Cypermethrin 
is also characterized as consisting of cis- and trans-configured 
diastereo-isomeric components based on orientation around its 
cyclopropane ring. Zeta-cypermethrin and alpha-cypermethrin are 
optimized stereo-isomeric mixtures of cypermethrin, each consisting of 
4 major components. These zeta-cypermethrin and alpha-cypermethrin 
components are the enriched trans- (alpha-S) and cis (cis2-R) isomeric 
orientations of cypermethrin, respectively. There is a practical 
analytical method for detecting and measuring levels of cypermethrin in 
or on food with a limit of detection (LOD) that allows monitoring of 
food with residues at or above the levels set in these tolerances GC 
with electron capture detection (GC/ECD) and liquid chromatography with 
tandem mass spectrometry (LC/MS/MS) methods are available. Contact:

tolerances in 40 CFR 180.434 for residues of the fungicide 
propiconazole, 1H-1,2,4-Triazole, 1-([2-(4-dichlorophenyl)-4-propyl-
1,3-dioxolan-2-yl]methyl)-, and its metabolites determined as 2,4-
dichlorobenzoic acid and expressed as parent compound, in or on barley, 
hay from 1.4 ppm to 30 ppm; barley, straw from 10 ppm to 20 ppm; 
barley, grain from 0.3 ppm to 3 ppm; oat, forage from 1.7 ppm to 4 ppm; 
oat, hay from 1.4 ppm to 15 ppm; oat, grain from 0.3 ppm to 3 ppm; rye, 
forage from 1.7 ppm to 9 ppm; rye, straw from 10 ppm to 9 ppm; wheat, 
forage from 1.7 ppm to 15 ppm; wheat, hay from 1.4 ppm to 30 ppm; 
wheat, straw from 10 ppm to 20 ppm; and grain, aspirated fraction from 
30 ppm to 108 ppm. Analytical methods adequate to determine parent 
propiconazole, total propiconazole as 2,4-dichlorobenzoic acid, and the 
triazole metabolites (1,2,4-Triazole, Triazole Alanine, and Triazole 
Acetic Acid) are available for enforcement purposes with LOD that allow 
monitoring of food with residues at or above the levels set in this 
tolerance. Contact: Heather Garvie, (703) 308-0034, email address:

LLC., P.O. Box 18300, Greensboro, NC 27419, requests to amend the 
tolerances in 40 CFR 180.507 for residues of the fungicide azoxystrobin 
(methyl (E)-2-(2-[6-(2-cyanophenoxy) pyrimidin-4-yloxy]phenyl)-3-
methoxyacrylate) and the Z isomer of azoxystrobin, (methyl (Z)-2-(2-[6-
(2-cyanophenoxy)pyrimidin-4-yloxy] phenyl)-3-methoxyacrylate), in or on 
animal commodities cattle, fat from 0.03 ppm to 0.3 ppm; hog, fat from 
0.010 ppm to 0.1 ppm and hog, meat from 0.01 to 0.02 ppm. An adequate 
analytical method, GC-NPD or in mobile phase by HPLC with ultra-violet 
(UV) detection (HPLC-UV), is available for enforcement purposes with a 
LOD that allows monitoring of food with residues at or above the levels 
set in these tolerances. The Analytical Chemistry section of the EPA 
concluded that the method(s) are adequate for enforcement. Analytical 
methods are also available for analyzing meat, milk, poultry and eggs 
which also underwent successful independent laboratory validations.
