Ethylene Oxide (ETO) Revised Risk Assessments; Notice of 
Availability, and Solicitation of Risk Reduction Options (Phase 5 of 6-
Phase Process)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY:  This notice announces the availability of EPA's revised risk 
assessments for the fumigant/sterilant pesticide ethylene oxide (ETO). 
In addition, this notice solicits public comment on risk reduction 
options for ETO. 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 ETO 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.

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; the medical 
industry; the spice industry; pesticide users; and members of the 
public interested in the sale, distribution, or use of pesticides. 
Since others may also 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 
http://www.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,

    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

II. Background

A. What Action is the Agency Taking?

     EPA is making available the Agency's revised risk assessments, 
initially issued for comment through a Federal Register notice 
published on August 3, 2005 (70 FR 44632) (FRL-7729-2); a response to 
comments; and related documents for ETO. EPA is also soliciting public 
comment on risk reduction options for ETO. EPA developed the risk 
assessments for ETO 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).
     ETO is a fumigant/sterilant used to sterilize medical or 
laboratory equipment, pharmaceuticals, and aseptic packaging, or to 
reduce microbial load on cosmetics, whole and ground spices or other 
seasoning materials, and artifacts, archival material or library 
objects.
     EPA is providing an opportunity, through this notice, for 
interested parties to provide risk management proposals or otherwise 
comment on risk management for ETO. Risks of concern associated with 
the use of ETO are as follows: The dietary risk assessment indicates 
that for all supported commodities, the acute dietary exposure 
estimates for ethylene chlorohydrin (a reaction product of ETO) are 
above the Agency's level of concern. In addition, the Agency's 
occupational exposure assessment for ETO's use as a sterilant for the 
spice and medical industries indicates that cancer risk are of concern 
at the current regulatory levels established by the Occupational Safety 
and Health Administration (OSHA) and recommended by the National 
Institute of Occupational Safety and Health (NIOSH). Non-cancer worker 
exposure/risk is estimated to be of concern at the OSHA permissible 
exposure limit (PEL), but not of concern at the NIOSH recommended 
exposure limit. Based on available data, the Agency anticipates the 
following spice and medical industry-related activities to result in 
potential worker exposure to ETO: Inhalation exposure to ETO during 
sterilization activities; inhalation exposure to off-gassed ETO from 
treated items during post-sterilization activities.
     A summary of these potential risks of concern as well as specific 
questions for which the Agency is requesting input, are provided in a 
separate document titled Request for Additional Information and Risk 
Management Suggestions for the Reregistration of Ethylene Oxide. In 
targeting these risks of concern, the Agency solicits

[[Page 9112]]

information on effective and practical risk reduction measures. In 
addition, a paper outlining benefits of various ETO uses is also 
included as a separate document. The Agency is interested in 
information related to these benefits.
     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 uses, risks, and other factors, ETO 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 ETO. 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 
the ETO 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.''
     Section 408(q) of the FFDCA, 21 U.S.C. 346a(q), requires EPA to 
review tolerances and exemptions for pesticide residues in effect as of 
August 2, 1996, to determine whether the tolerance or exemption meets 
the requirements of section 408(b)(2) or (c)(2) of FFDCA. This review 
is to be completed by August 3, 2006.
