Chlorflurenol Risk Assessment; Notice of Availability, and Risk 
Reduction Options

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: This notice announces the availability of EPA's risk 
assessment(s), and related documents for the herbicidal pesticide 
chlorflurenol, 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 chlorflurenol through a modified, 4-
Phase public participation process that the Agency uses to involve the 
public in developing pesticide reregistration and tolerance 
reassessment decisions. This is Phase 3 of the 4-Phase process. Through 
these programs, EPA is ensuring that all pesticides meet current health 
and safety standards.

DATES: Comments must be received on or before January 2, 2007.

ADDRESSES: Submit your comments, identified by docket identification 
(ID) number EPA-HQ-OPP-2006-0874, by one of the following methods:

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 ecological 
risk assessments and related documents for chlorflurenol and soliciting 
public comment on risk management ideas or proposals. EPA developed the 
risk assessments and risk characterization for chlorflurenol 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).
    Chlorflurenol is a nonfood use herbicide, plant growth retardant, 
and plant growth regulator used in agricultural, commercial, and 
residential settings. As an herbicide or plant growth retardant, it is 
used for the postemergent control of annual grasses, broadleaf weeds, 
trees, shrubs and vines for nonagricultural rights-of-way (e.g., 
utility lines), lawns, ornamental turf (including golf courses and 
parks), and high density forestry management areas. As a plant growth 
regulator, chlorflurenol is used in the production of pineapple 
planting material (sliplets); this use is considered to be nonfood as 
no finite residues are expected. Chlorflurenol is registered in 
emulsifiable concentrate and granular formulations.
    EPA is providing an opportunity, through this notice, for 
interested parties to provide comments and input on the Agency's risk 
assessments for chlorflurenol. Such comments and input could address, 
for example, the availability of additional data to further refine the 
risk assessments, such as worker, residential, and drinking water 
exposure data and ecological effects data, 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 chlorflurenol. Risks of concern 
associated with the use of chlorflurenol are: dermal occupational risks 
from applying liquid sprays with rights-of-way equipment at 3 to 5 lbs 
active ingredient/acre (a.i./A); post-application dermal risks for 
adults at 3 lbs a.i./A; post-application dermal risks to toddlers from 
high contact activity on lawns at 1 to 3 lbs a.i./A; and risks to 
infants from chronic exposure to drinking water using modeled ground 
water estimated concentrations. Risk could not be precluded for 
terrestrial and aquatic organisms and plants due to a lack of data; 
limited data suggest potential chronic risk to mammals. 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 chlorflurenol, 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

[[Page 64264]]

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 
chlorflurenol, a modified, 4-Phase process with one comment period and 
ample opportunity for public consultation seems appropriate in view of 
its 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 ADDRESSES, 
and must be received by EPA on or before the closing date. Comments 
will become part of the Agency Docket for chlorflurenol. 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.''
