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 the first page of 
your comment. Please ensure that your comments are

[[Page 41350]]

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. Go directly to EPA Dockets at http://www.epa.gov/edocket
, and follow the online instructions for submitting comments. 
Once in the system, select ``search,'' and then key in docket ID number 
OPP-2003-0230. The system is an ``anonymous access'' system, which 
means EPA will not know your identity, e-mail address, or other contact 
information unless you provide it in the body of your comment.

Attention: Docket ID number OPP-2003-0230. In contrast to EPA's 
electronic public docket, EPA's e-mail system is not an ``anonymous 
access'' system. If you send an e-mail comment directly to the docket 
without going through EPA's electronic public docket, EPA's e-mail 
system automatically captures your e-mail address. E-mail addresses 
that are automatically captured by EPA's e-mail system are included as 
part of the comment that is placed in the official public docket, and 
made available in EPA's electronic public docket.
    iii. Disk or CD ROM. You may submit comments on a disk or CD ROM 
that you mail to the mailing address identified in Unit I.C.2. These 
electronic submissions will be accepted in WordPerfect or ASCII file 
format. Avoid the use of special characters and any form of encryption.

ID Number OPP-2003-0230. Such deliveries are only accepted during the 
docket's normal hours of operation as identified in Unit I.B.1.

D. How Should I Submit CBI to the Agency?

    Do not submit information that you consider to be CBI 
electronically through EPA's electronic public docket or by e-mail. You 
may claim information that you submit to EPA as CBI by marking any part 
or all of that information as CBI (if you submit CBI on disk or CD ROM, 
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 CBI). Information so marked will not be disclosed except in 
accordance with procedures set forth in 40 CFR part 2.
    In addition to one complete version of the comment that includes 
any 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 and EPA's electronic public docket. If you submit 
the copy that does not contain CBI on disk or CD ROM, mark the outside 
of the disk or CD ROM clearly that it does not contain CBI. Information 
not marked as CBI will be included in the public docket and EPA's 
electronic public docket without prior notice. If you have any 
questions about CBI or the procedures for claiming CBI, please consult 
the person listed under FOR FURTHER INFORMATION CONTACT.

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

I. PURAC America, Inc.

PP OF6179

    EPA has received a pesticide petition (PP OF6179) from PURAC 
America, Inc., 111 Barclay Boulevard, Lincolnshire Corporate Center, 
Lincolnshire, IL 60069 proposing, pursuant to section 408(d) of FFDCA, 
21 U.S.C. 346a(d), to amend 40 CFR 180.950 to establish an exemption 
from the requirement of a tolerance for 2-ethylhexyl-L-lactate, when 
used in accordance with good agricultural or manufacturing practice. 
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. Toxicological Profile

    1. Acute toxicity. The oral LD50 of 2-ethylhexyl-L-
lactate in rats is greater than 2,000 mg/kg (per Organization for 
Economic Cooperation and Development (OECD) Guideline No. 401). In the 
acute oral study, 5 rats per sex, per group were used. The test 
substance was diluted with water (20% (w/v) and given by gavage at a 
dose of 10 milligrams/kilogram (mg/kg). Clinical observations, 
mortality, body weights and gross pathological changes were recorded 
during a 14-day observation period. Piloerection was seen for up to 4 
hours after treatment, but no gross necropsy changes were noted.
    2. Genotoxicity. Ames testing of a similar lactate, ethyl-L-lactate 
did not show any activity.
    3. Reproductive and developmental toxicity. The embryotoxicity and 
teratogenicity of aerosolized 2-ethylhexyl lactate at 200 and 600 mg/
m\3\ was studied. Only minor developmental effects, most attributable 
to the stress conditions, and no teratogenic effects were observed.
    4. Subchronic toxicity. Subacute inhalation studies have been 
conducted at concentrations up to 600 mg/m\3\. For aerosol exposure, 2-
ethylhexyl-L-lactate was noted to cause minimal damage, the vapor being 
slightly less toxic than the aerosol. Lactates do not appear to cause 
systemic toxicity, except at very high concentration (1,800 mg/m\3\ or 
higher). These systemic effects may be secondary to severe irritation 
seen at high doses.
    5. Animal metabolism. The in vitro hydrolysis of lactate esters 
(methyl, ethyl, butyl, pentyl, isoamyl, isopropyl, isobutyl, 2-
ethylhexyl) in rat olfactory epithelium homogenate has been evaluated. 
In general, of the eight lactates evaluated, the rat nasal epithelium 
showed increased capacity to hydrolyze the lactates and increased 
affinity with increasing molecular weight (increase in alcohol chain 
length). Based on the similarity of effects and kinetic parameters, it 
appears that lactic acid is most likely the cause of the lactate 
toxicity. The in vitro hydrolysis of 2-ethylhexyl lactate and di-(2-
ethylhexyl)-phthalate by homogenates of rat liver, small intestinal 
mucosa, blood, skin and caecum content was investigated. The study 
concluded that 2-ethylhexyl-lactate will be effectively hydrolysed 
before, during or rapidly after absorption. Results showed the most 
rapid hydrolysis was in the intestinal mucosa, followed in decreasing 
order by the liver, caecum, blood, and skin.
    6. Metabolite toxicology. 2-Ethylhexyl-L-lactate is rapidly 
hydrolyzed in the body and environment to lactic acid and 2-
ethylhexanol (both are listed as exempt from requirements for a 
tolerance under 40 CFR 180.1001). Lactic acid is a metabolic break down 
product of all lactates. It is a normal metabolite in humans and is 
found in or added to foods (21 CFR 172.515). Endogenous production of 
L(+) lactate in a resting human is 100-124 grams per day. Lactic acid 
oral LD50 in rats is 3,730 mg/kg. It is not active in 
mutagenic tests. It will produce skin and eye irritation at high 
concentrations. The 2-ethylhexanol has an exemption from tolerance 
under 40 CFR 180.1001 with no limit on use as a cosolvent, defoamer or 
solvent for all pesticides used before crop emerges from soil and in 
herbicides before or after crop emergence.

B. Aggregate Exposure

    Non-dietary exposure. 2-Ethylhexyl-L-lactate will be used at an 
application rate of between 0.4 and 1.7 lb/acre as part of the emulsion 
concentrate or as a solvent for herbicides, fungicides, insecticides, 
and, other pesticide formulations. The low vapor pressure would tend to 
keep airborne exposure low.
