EPA is releasing for public comment its human health and environmental fate and effects risk assessments and related documents for endothall, a dicarboxylic acid herbicide, and encouraging the public to suggest risk management ideas or proposals. Endothall is used as an aquatic herbicide, biocide, and a desiccant. As VerDate jul<14>2003 16:48 May 10, 2005 Jkt 205001 an aquatic herbicide, endothall is used to control submerged aquatic vegetation and algae in lakes, ponds, and irrigation canals. As a biocide, endothall is used to control mollusks in once-through cooling water systems. As a desiccant, endothall is used on cotton, hops, potatoes, clover, and alfalfa. EPA developed the risk assessments and preliminary risk reduction options for endothall through a modified version of its public process for making pesticide reregistration eligibility and tolerance reassessment decisions. Through these programs, EPA is ensuring that pesticides meet current standards under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (FQPA). Endothall is a dicarboxylic herbicide used as an aquatic herbicide, biocide, and a desiccant. Currently, three forms of endothall are registered as active ingredients in end-use-products: Endothall acid, endothall dipotassium salt, and endothall N,Ndimethylalkylamine salt. All three forms are used as aquatic herbicides, but only the N,N-dimethylalkylamine salt is used as a desiccant on hops, potatoes, cotton, clover, and alfalfa. The Agency is concerned with occupational exposures for aquatic applications. In addition, the Agency is concerned with environmental risks associated with the use of endothall, primarily the use of the N,Ndimethylalkylamine salt. At this time the Agency has limited information about the environmental fate and toxicity characteristics of this form of endothall, creating uncertainties in the risk assessment. To adequately protect the environment it may be necessary to change current use and/or application practices. Specific areas in which the Agency is requesting public input are provided in a separate document available in the endothall docket. EPA is providing an opportunity, through this notice, for interested parties to provide comments and input on the Agency’s risk assessments for endothall. Such comments and input could address, for example, the availability of additional data to further refine the risk assessments, such as worker exposure data, or could address the Agency’s risk assessment methodologies and assumptions as applied to this specific pesticide. Through this notice, EPA is providing an opportunity for interested parties to provide risk management proposals or otherwise comment on risk management. PO 00000 Frm 00020 Fmt 4703 Sfmt 4703 EPA seeks to achieve environmental justice, the fair treatment and meaningful involvement of all people, regardless of race, color, national origin, or income, 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, unusually high exposure to endothall, compared to the general population. EPA is applying the principles of public participation to all pesticides undergoing reregistration and tolerance reassessment. The Agency’s Pesticide Tolerance Reassessment and Reregistration; Public Participation Process, published in the Federal Register on May 14, 2004, (69 FR 26819) explains that in conducting these programs, the Agency is tailoring its public participation process to be commensurate with the level of risk, extent of use, complexity of the issues, and degree of public concern associated with each pesticide. For endothall, a modified, 4–Phase process with 1 comment period and ample opportunity for public consultation seems appropriate in view of its refined risk assessments, and limited use. However, if as a result of comments received during this comment period EPA finds that additional issues warranting further discussion are raised, the Agency may lengthen the process and include a second comment period, as needed. All comments should be submitted using the methods in Unit I. of the SUPPLEMENTARY INFORMATION, and must be received by EPA on or before the closing date. Comments will become part of the Agency Docket for Endothall. Comments received after the close of the comment period will be marked ‘‘late.’’ EPA is not required to consider these late comments. B. What is the Agency’s Authority for Taking this Action? Section 4(g)(2) of FIFRA as amended directs that, after submission of all data concerning a pesticide active ingredient, ‘‘the Administrator shall determine whether pesticides containing such active ingredient are eligible for reregistration,’’ before calling in product specific data on individual end-use products and either reregistering products or taking other ‘‘appropriate regulatory action.’’ Section 408(q) of the FFDCA, 21 U.S.C. 346a(q), requires EPA to review tolerances and exemptions for pesticide E:\FR\FM\11MYN1.SGM 11MYN1 Federal Register / Vol. 70, No. 90 / Wednesday, May 11, 2005 / Notices residues in effect as of August 2, 1996, to determine whether the tolerance or exemption meets the requirements of section 408(b)(2) or (c)(2) of FFDCA. This review is to be completed by August 3, 2006. List of Subjects Environmental protection, Pesticides and pests. Dated: April 28, 2005.

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 the 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. Go directly to EPA Dockets at https://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-2004-0370. 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.
    ii.  E-mail. Comments may be sent by e-mail to opp-docket@epa.gov, 
Attention: Docket ID Number OPP-2004-0370. 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.
    2.  By mail. Send your comments to: Public Information and Records 
Integrity Branch (PIRIB) (7502C), Office of Pesticide Programs (OPP), 
Environmental Protection Agency, 1200 Pennsylvania Ave., NW., 
Washington, DC 20460-0001, Attention: Docket ID Number OPP-2004-0370.
    3. By hand delivery or courier. Deliver your comments to: Public 
Information and Records Integrity Branch (PIRIB), Office of Pesticide 
Programs (OPP), Environmental Protection Agency, Rm. 119, Crystal Mall 
2, 1801 S. Bell St., Arlington, VA, Attention: Docket ID 
Number OPP-2004-0370. 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

[[Page 24784]]

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?

    You may find the following suggestions helpful for preparing your 
comments:
    1. Explain your views as clearly as possible.
    2. Describe any assumptions that you used.
    3. Provide any technical information and/or data you used that 
support your views.
    4. If you estimate potential burden or costs, explain how you 
arrived at your estimate.
    5. Provide specific examples to illustrate your concerns.
    6. Offer alternatives.
    7. Make sure to submit your comments by the comment period deadline 
identified.
    8. To ensure proper receipt by EPA, identify the appropriate docket 
ID number in the subject line on the first page of your response. It 
would also be helpful if you provided the name, date, and Federal 
Register citation related to your comments.

II. Background

A. What Action is the Agency Taking?

    EPA is releasing for public comment its human health and 
environmental fate and effects risk assessments and related documents 
for endothall, a dicarboxylic acid herbicide, and encouraging the 
public to suggest risk management ideas or proposals. Endothall is used 
as an aquatic herbicide, biocide, and a desiccant. As an aquatic 
herbicide, endothall is used to control submerged aquatic vegetation 
and algae in lakes, ponds, and irrigation canals. As a biocide, 
endothall is used to control mollusks in once-through cooling water 
systems. As a desiccant, endothall is used on cotton, hops, potatoes, 
clover, and alfalfa. EPA developed the risk assessments and preliminary 
risk reduction options for endothall through a modified version of its 
public process for making pesticide reregistration eligibility and 
tolerance reassessment decisions. Through these programs, EPA is 
ensuring that pesticides meet current standards under the Federal 
Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Federal 
Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality 
Protection Act of 1996 (FQPA).
    Endothall is a dicarboxylic herbicide used as an aquatic herbicide, 
biocide, and a desiccant. Currently, three forms of endothall are 
registered as active ingredients in end-use-products: Endothall acid, 
endothall dipotassium salt, and endothall N,N-dimethylalkylamine salt. 
All three forms are used as aquatic herbicides, but only the N,N-
dimethylalkylamine salt is used as a desiccant on hops, potatoes, 
cotton, clover, and alfalfa.
    The Agency is concerned with occupational exposures for aquatic 
applications. In addition, the Agency is concerned with environmental 
risks associated with the use of endothall, primarily the use of the 
N,N-dimethylalkylamine salt. At this time the Agency has limited 
information about the environmental fate and toxicity characteristics 
of this form of endothall, creating uncertainties in the risk 
assessment. To adequately protect the environment it may be necessary 
to change current use and/or application practices. Specific areas in 
which the Agency is requesting public input are provided in a separate 
document available in the endothall docket.
    EPA is providing an opportunity, through this notice, for 
interested parties to provide comments and input on the Agency's risk 
assessments for endothall. Such comments and input could address, for 
example, the availability of additional data to further refine the risk 
assessments, such as worker exposure data, or could address the 
Agency's risk assessment methodologies and assumptions as applied to 
this specific pesticide. Through this notice, EPA is providing an 
opportunity for interested parties to provide risk management proposals 
or otherwise comment on risk management.
    EPA seeks to achieve environmental justice, the fair treatment and 
meaningful involvement of all people, regardless of race, color, 
national origin, or income, 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, unusually high exposure to endothall, compared to the 
general population.
    EPA is applying the principles of public participation to all 
pesticides undergoing reregistration and tolerance reassessment. The 
Agency's Pesticide Tolerance Reassessment and Reregistration; Public 
Participation Process, published in the Federal Register on May 14, 
2004, (69 FR 26819) explains that in conducting these programs, the 
Agency is tailoring its public participation process to be commensurate 
with the level of risk, extent of use, complexity of the issues, and 
degree of public concern associated with each pesticide. For endothall, 
a modified, 4-Phase process with 1 comment period and ample opportunity 
for public consultation seems appropriate in view of its refined risk 
assessments, and limited use. However, if as a result of comments 
received during this comment period EPA finds that additional issues 
warranting further discussion are raised, the Agency may lengthen the 
process and include a second comment period, as needed.
    All comments should be submitted using the methods in Unit I. of 
the SUPPLEMENTARY INFORMATION, and must be received by EPA on or before 
the closing date. Comments will become part of the Agency Docket for 
Endothall. Comments received after the close of the comment period will 
be marked ``late.'' EPA is not required to consider these late 
comments.

B. What is the Agency's Authority for Taking this Action?

    Section 4(g)(2) of FIFRA as amended directs that, after submission 
of all data concerning a pesticide active ingredient, ``the 
Administrator shall determine whether pesticides containing such active 
ingredient are eligible for reregistration,'' before calling in product 
specific data on individual end-use products and either reregistering 
products or taking other ``appropriate regulatory action.''
    Section 408(q) of the FFDCA, 21 U.S.C. 346a(q), requires EPA to 
review tolerances and exemptions for pesticide

[[Page 24785]]

residues in effect as of August 2, 1996, to determine whether the 
tolerance or exemption meets the requirements of section 408(b)(2) or 
(c)(2) of FFDCA. This review is to be completed by August 3, 2006.
