ENVIRONMENTAL PROTECTION AGENCY

[EPA-HQ-OPP-2007-0973; FRL-8344-4]

 
Siduron Risk Assessments; Notice of Availability, and Risk 
Reduction Options

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: This notice announces the availability of EPA's risk 
assessments, and related documents for the pesticide siduron, and opens 
a public comment period on these documents. The public is encouraged to 
suggest risk management ideas or proposals to address the risks 
identified. EPA is developing a Reregistration Eligibility Decision 
(RED) for siduron through a modified, 4-Phase public participation 
process that the Agency uses to involve the public in developing 
pesticide reregistration decisions. This is Phase 3 of a 4-Phase 
process. Through this program, EPA is ensuring that all pesticides meet 
current health and safety standards.

DATES: Comments must be received on or before February 19, 2008.

ADDRESSES: Submit your comments, identified by docket identification 
(ID) number EPA-HQ-OPP-2007-0973, by one of the following methods:
     Federal eRulemaking Portal: http://www.regulations.gov.

Docket (7502P), Environmental Protection Agency, 1200 Pennsylvania 
Ave., NW., Washington, DC 20460-0001.
     Delivery: OPP Regulatory Public Docket (7502P), 
Environmental Protection Agency, Rm. S-4400, One Potomac Yard (South

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this Action Apply to Me?

    This action is directed to the public in general, and may be of 
interest to a wide range of stakeholders including environmental, human 
health, and agricultural advocates; the chemical industry; pesticide 
users; and members of the public interested in the sale, distribution, 
or use of pesticides. Since others also may be interested, the Agency 
has not attempted to describe all the specific entities that may be 
affected by this action. 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 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.

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 siduron and soliciting public comment on risk management ideas or 
proposals. EPA developed the risk assessments and risk characterization 
for siduron 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).
    Sidruon is a selective, systemic preemergence herbicide used to 
control grassy weeds in stands of cool-season grass. It is registered 
for use on lawns, golf courses, and sod farms. Siduron is not 
registered for any food uses.
    EPA is providing an opportunity, through this notice, for 
interested parties to provide comments and input on the Agency's risk 
assessments for siduron. Such comments and input could address, for 
example, the availability of additional data to further refine the risk 
assessments, or could address the Agency's risk assessment 
methodologies and assumptions as applied to this specific pesticide.
    Through this notice, EPA also is providing an opportunity for 
interested parties to provide risk management proposals or otherwise 
comment on risk management for siduron. Risks of concern associated 
with the use of siduron are: Dermal exposure risks to residential 
handlers from loading/applying granular products with a belly-grinder; 
residential post-application dermal exposure risks for scenarios 
involving toddlers, youths, and adults; dermal exposure risks to 
occupational handlers; chronic risks to freshwater and estuarine/marine 
invertebrates; and risks to freshwater non-vascular plants. In 
targeting these risks of concern, the Agency solicits information on 
effective and practical risk reduction measures.
    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 siduron, 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) (FRL-7357-9), 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 siduron, a modified, 4-Phase process with 1 comment 
period and ample opportunity for public consultation seems appropriate 
in view of its limited use and few complex issues. 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 ADDRESSES, 
and must be received by EPA on or before the closing date. Comments 
will become part of the Agency Docket for sidruon. 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.''
