Acrolein Revised Risk Assessments; Notice of Availability and 
Solicitation of Risk Reduction Options

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: This notice announces the availability of EPA's revised risk 
assessments for the pesticide acrolein. In addition, this notice 
solicits public comment on risk reduction and alternative options for 
acrolein (Phase 5 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 the full, 6-Phase public participation 
process that the Agency uses to involve the public in developing 
pesticide reregistration and tolerance reassessment decisions. Through 
these programs, EPA is ensuring that all pesticides meet current health 
and safety standards.

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

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.

II. Background

A. What Action is the Agency Taking?

    EPA is making available the Agency's revised risk assessments for 
both ecological and human health risk, initially issued for comment 
through two Federal Register notices published on July 25, 2007 (72 FR 
40857 (FRL-8140-8) and November 2, 2007 (72 FR 62230 -) (FRL-8154-4), 
respectively; a response to comments, and related documents for 
acrolein. EPA also is soliciting public comment on risk reduction and 
alternative options for acrolein. In addition, in order to allow a more 
completed benefits assessment for identified risks of concern, the 
Agency is soliciting information to several questions referenced in 
their alternative assessment summary and uncertainties document to help 
better understand the importance of acrolein to irrigation. EPA 
developed the risk assessments for acrolein as part 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).
    Acrolein is registered as a non-food use aquatic herbicide 
Magnacide H: (EPA Registration: 10707-9) used in irrigation 
canals and holding ponds. It is a non-specific biocide that controls 
aquatic weeds by breaking down their cell walls. Acrolein is formulated 
as a liquid, and is metered directly into irrigation canals and 
reservoirs. Acrolein is also used as a bactericide Magnacide B: (EPA 
Registration : 10707-10) during the production of petroleum. 
This product is used to control bacteria that produce corrosive 
hydrogen sulfide in oil water ststems. For the bactericide use, 
acrolein is injected deep into oil field wells.
    EPA is providing an opportunity, through this notice, for 
interested parties to provide risk management proposals or otherwise 
comment on risk management for acrolein. Risks of concern that exceed 
the Agency's level of concern associated with the use of acrolein are 
exposure to bystanders during application to irrigation canals. In 
addition, the Agency has identified several ecological risks that 
exceed its level of concern following acute exposures to freshwater 
fish, invertebrates, non-target aquatic plants, and estuarine/marine 
invertebrates. In targeting these risks of concern, the Agency solicits 
information on effective and practical risk reduction measures.
    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, EPA is tailoring its public participation process to be 
commensurate with the level of risk, extent of use, complexity of 
issues, and degree of public concern associated with each pesticide. 
Due to its acute risks, multiple ecological incidents, and worker 
incidents acrolein is being reviewed through the full 6-Phase public 
participation process.
    All comments should be submitted using the methods in ADDRESSES, 
and must be received by EPA on or before the closing date. Comments and 
proposals 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.
    After considering comments received, EPA will develop and issue for 
comment the acrolein RED.

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.''
