Start Preamble

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.

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.Start Printed Page 62232

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.”
