Certain types of information will not be placed in EPA's Dockets. Information claimed as CBI and other information whose disclosure is restricted by statute, which is not included in the official public docket, will not be available for public viewing in EPA's electronic public docket. EPA's policy is that copyrighted material will not be placed in EPA's electronic public docket but will be available only in printed, paper form in the official public docket. To the extent feasible, publicly available docket materials will be made available in EPA's electronic public docket. When a document is selected from the index list in EPA Dockets, the system will identify whether the document is available for viewing in EPA's electronic public docket. Although not all docket materials may be available electronically, you may still access any of the publicly available docket materials through the docket facility identified in Unit I.B.1. EPA intends to work towards providing electronic access to all of the publicly available docket materials through EPA's electronic public docket.

For public commenters, it is important to note that EPA's policy is that public comments, whether submitted electronically or in paper, will be made available for public viewing in EPA's electronic public docket as EPA receives them and without change, unless the comment contains copyrighted material, CBI, or other information whose disclosure is restricted by statute. When EPA identifies a comment containing copyrighted material, EPA will provide a reference to that material in the version of the comment that is placed in EPA's electronic public docket. The entire printed comment, including the copyrighted material, will be available in the public docket.

Public comments submitted on computer disks that are mailed or delivered to the docket will be transferred to EPA's electronic public docket. Public comments that are mailed or delivered to the docket will be scanned and placed in EPA's electronic public docket. Where practical, physical objects will be photographed, and the photograph will be placed in EPA's electronic public docket along with a brief description written by the docket staff.

C. How and to Whom Do I Submit Comments?

You may submit comments electronically, by mail, or through hand delivery/courier. To ensure proper receipt by EPA, identify the appropriate docket ID number in the subject line on Start Printed Page 8655the first page of your comment. Please ensure that your comments are submitted within the specified comment period. Comments received after the close of the comment period will be marked “late.” EPA is not required to consider these late comments. If you wish to submit CBI or information that is otherwise protected by statute, please follow the instructions in Unit I.D. Do not use EPA Dockets or e-mail to submit CBI or information protected by statute.

1. Electronically. If you submit an electronic comment as prescribed in this unit, EPA recommends that you include your name, mailing address, and an e-mail address or other contact information in the body of your comment. Also include this contact information on the outside of any disk or CD ROM you submit, and in any cover letter accompanying the disk or CD ROM. This ensures that you can be identified as the submitter of the comment and allows EPA to contact you in case EPA cannot read your comment due to technical difficulties or needs further information on the substance of your comment. EPA's policy is that EPA will not edit your comment, and any identifying or contact information provided in the body of a comment will be included as part of the comment that is placed in the official public docket, and made available in EPA's electronic public docket. 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.

i. EPA Dockets. Your use of EPA's electronic public docket to submit comments to EPA electronically is EPA's preferred method for receiving comments.

Pytech Chemicals GmbH

PP 4F6812

EPA has received a pesticide petition (4F6812) from Pytech Chemicals GmbH, 9330 Zionsville Road, Indianapolis, IN 46268 proposing, pursuant to section 408(d) of the FFDCA, 21 U.S.C. 346a(d), to amend 40 CFR part 180 by adding gamma-cyhalothrin ((S)-α-cyano-3-phenoxybenzyl (Z)-(1R,3R)-3-(2-chloro-3,3,3-trifluoripropenyl)-2,2-dimethylcyclopropanecarboxylate) to the tolerance expression of lambda-cyhalothrin, ((S)-α-cyano-3-phenoxybenzyl-(Z)-(1R,3R)-3-(2-chloro-3,3,3-trifluoroprop-1-enyl)-2,1-dimethylcyclopropanecarboxylate and (R)-alpha-cyano-3-phenoxybenzyl-(Z)-(1S,3S)-3-(2-chloro-3,3,3-trifluoroprop-1-enyl)-2,2-dimethylcyclopropanecarboxylate). Gamma-cyhalothrin is the isolated active isomer of lambda-cyhalothrin. EPA has determined that the petition contains data or information regarding the elements set forth in section 408(d)(2) of the FFDCA; however, EPA has not fully evaluated the sufficiency of the submitted data at this time or whether the data support granting of the petition. Additional data may be needed before EPA rules on the petition.

A. Residue Chemistry

1. Plant metabolism. Gamma-cyhalothrin relies on the metabolism data conducted on lambda-cyhalothrin, which has been thoroughly tested and is adequately understood.

2. Analytical method. An adequate analytical method is available for enforcement purposes.

3. Magnitude of residues. Gamma-cyhalothrin, the isolated active isomer, will be applied at half the application rates of lambda-cyhalothrin. Comparison studies of gamma-cyhalothrin versus lambda-cyhalothrin used on the representative crops of tomatoes, sweet corn, broccoli, and cottonseed prove that the established tolerances for lambda-cyhalothrin will be sufficient to cover the potential residues of gamma-cyhalothrin.

B. Toxicological Profile

1. Acute toxicity. The acute oral lethal dose (LD)50 was >50 milligrams/kilogram body weight (mg/kg bwt) in male rats and 55 mg/kg bwt in female rats, acute dermal LD50 was >1,500 mg/kg bwt in male rats and 1,643 mg/kg bwt in female rats and the 4-hour lethal concentration (LC)50 for male rats was 40.2 milligrams/meter (mg/m3) and, for female rats, 28.2 mg/m3.

2. Genotoxicity. The following genotoxicity tests were all negative: Salmonella, E.coli reverse mutation assay, mouse bone marrow micronucleus test, in vitro chromosomal aberration in rat lymphocytes, and mouse lymphoma forward mutation assay.

3. Reproductive and developmental toxicity. A developmental toxicity study in rats given gavage doses of 0, 0.1, 0.5, and 2 mg/kg/day with no developmental toxicity observed under the conditions of the study. The developmental no observed adverse effect level (NOAEL) is greater than 2 mg/kg/day, the highest dose tested (HDT). The maternal NOAEL and lowest observed adverse effect level (LOAEL) are established at 0.5 and 2 mg/kg/day, respectively, based on reduced body weight, body weight gain, and feed consumption.

4. Subchronic toxicity. A 90-day feeding study in rats fed doses of 0, 2.5, 10, 50, and 100 parts per million (ppm) with a NOAEL of 50 ppm and a LOAEL of 100 ppm based on mortality, decreased feed consumption, decreased body weights, and increased relative liver and kidney weight at 100 ppm.

5. Chronic toxicity. Gamma-cyhalothrin, and lambda-cyhalothrin are contained within the chemical cyhalothrin. Cyhalothrin consists of four isomers, lambda-cyhalothrin consists of two of these isomers and gamma-cyhalothrin is the single active isomer contained in both. The chronic studies were conducted on cyhalothrin.

6. Metabolite toxicology. The Agency has previously determined that the metabolites of lambda-cyhalothrin are not of toxicological concern and need not be included in the tolerance expression. Given this determination, it is concluded that there is no need to discuss metabolite toxicity.

7. Endocrine disruption. No studies have been conducted to investigate the potential of gamma-cyhalothrin to induce estrogenic or other endocrine effects. However, no evidence of such effects has been noted in the battery of toxicity studies which have been conducted on cyhalothrin/lambda-cyhalothrin, and there is no reason to suspect that any such effects would be likely.

C. Aggregate Exposure

The Agency has conducted an extensive assessment of the aggregate exposure. Results are reported in the Federal Register of September 27, 2002 (FR 67 60902) (FRL-7200-1).

D. Cumulative Effects

For purposes of this request, it has been assumed that cyhalothrin (i.e., gamma-cyhalothrin, and lambda-cyhalothrin) does not have a common mechanism of toxicity with other substances.

E. Safety Determination

The Agency has conducted an extensive assessment of the aggregate exposure. Results are reported in the Federal Register of September 27, 2002.

F. International Tolerances

There are Codex maximum residue levels established or pending for residues of cyhalothrin, as the sum of all isomers, in or on the following crops and commodities.

CropMRL (mg/kg)
Apricots0.2
Cabbage, head0.2
Cherries0.2
Cotton seed0.02
Cottonseed, oil0.02
Oil seed (including rapeseed oil)0.02
Peaches0.2
Plums0.1
Pome fruit0.1
Potatoes0.02
Tree nuts (shelled and unshelled)0.05

Canadian maximum residue levels of 0.1 ppm for pome fruit, stone fruit, and canola are established in Canada for lambda-cyhalothrin based on the “negligble” residue clause of Canadian Food and Drug Act Regulations (B.15.002(1)).
