ENVIRONMENTAL PROTECTION AGENCY

[EPA-HQ-OPP-2007-0588; FRL-8154-4]


Acrolein Human Health Risk Assessment; Notice of Availability

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY:  This notice announces the availability of EPA's human health 
risk assessment, and related documents for the pesticide acrolein, and 
opens a public comment period on these documents (Phase 3 of 6-Phase 
Process). 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 acrolein through a 6-
Phase public participation process that the Agency uses to involve the 
public in developing pesticide reregistration decisions. Through this 
process, EPA is ensuring that all pesticides meet current health and 
safety standards.

DATES: Comments must be received on or before January 2, 2008.

ADDRESSES: Submit your comments, identified by docket identification 
(ID) number EPA-HQ-OPP-2007-0588, 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 risk 
assessment and related documents for acrolein, an aldehyde, and 
soliciting public comment on risk management ideas or proposals. 
Acrolein is primarily used in irrigation canals and reservoirs to treat 
aquatic weeds, such as pondweed. Its secondary use is in oil fields, as 
a biocide to remove bacteria during petroleum production. EPA developed 
the human health risk assessment and risk characterization for acrolein 
as a part of its public process for making its pesticide reregistration 
eligibility decision. Through this program, EPA is ensuring that 
pesticides meet current standards under the Federal Insecticide, 
Fungicide, and Rodenticide Act (FIFRA). The ecological risk assessment 
for acrolein was posted in the docket for the Phase 3 public comment 
period on July 25, 2007. This comment period closed on September 23, 
2007. The Agency intends to review the comments for both the ecological 
and human health risk assessments, revise the risk assessments if 
appropriate from comments received, and provide an additional public 
comment period on both the ecological and human health risk assessments 
for acrolein.
    Acrolein is registered as a non-food use aquatic herbicide used 
primarily in irrigation canals. It is a non-specific biocide that 
treats aquatic weeds by breaking down their cell walls. Acrolein is 
formulated as a liquid, and is metered directly into irrigation canals 
or reservoirs.
     EPA is providing an opportunity, through this notice, for 
interested parties to provide comments and input on the Agency's human 
health risk assessment for acrolein. Such comments and input could 
address, for example, the availability of additional data to further 
refine the risk assessments, such as residue data on root and tuber 
crops, air monitoring data, and residential bystander exposure and risk 
information, 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 acrolein. Risks of concern associated 
with the use of acrolein include:
    1. Exposure to workers during application periods, and
    2. Bystanders during post-application periods.
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 acrolein, 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 acrolein the full, 6-Phase process with 2 comment 
periods and ample opportunity for public consultation seems appropriate 
in view of its large number of users in the Pacific Northwest, multiple 
incidents, complex issues, acute toxicity, and numerous affected 
stakeholders.
    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 acrolein. 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.''
