Ethylene Oxide; Preliminary Determination to Terminate Special 
Review

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: This notice announces EPA's preliminary determination to 
terminate the Special Review of ethylene oxide (ETO). On January 27, 
1978, EPA initiated Special Review based on developmental toxicity, 
mutagenicity, and neurotoxic effects in workers (43 FR 3801). In the 
early 1980s, the carcinogenicity of ETO became of concern and was added 
to the Special Review. Since the initiation of the Special Review, 
additional data and more comprehensive reviews of potential risks 
associated with ETO exposure have been completed, including those 
described in the 2006 Tolerance Reassessment and Risk Management 
Decision (TRED) (http://www.epa.gov/oppsrrd1/REDs/ethylene_oxide_
tred.pdf) and the 2008 Reregistration Eligibility Decision (RED) 
(http://www.epa.gov/oppsrrd1//REDs/ethylene-oxide-red.pdf) for ETO. In 
the 2008 RED, the Agency addressed occupational risk concerns that were 
the focus of the Special Review. During the reregistration process EPA 
conducted a public, intensive review of ETO risks and benefits to 
determine whether or not ETO registrations meet the Federal 
Insecticide, Fungicide, Rodenticide Act (FIFRA) standard for 
registration. The Agency determined that the benefits of ETO use 
outweigh the occupational risks associated with its use provided that 
the risk mitigation measures outlined in the RED are adopted and label 
amendments are made to reflect those measures. Because the risks that 
were the basis of the Special Review have been evaluated and the Agency 
has made a determination under FIFRA, as outlined above, the Agency is 
proposing to terminate the Special Review of ETO.

II. Background

A. What Action is the Agency Taking?

    On January 27, 1978, EPA initiated Special Review based on 
developmental toxicity, mutagenicity, and neurotoxic effects in workers 
(43 FR 3801). In the early 1980s, the carcinogenicity of ETO became of 
concern and was added to the Special Review. Since the initiation of 
the Special Review, additional data and more comprehensive reviews of 
potential risks associated with ETO exposure have been completed, 
including those described in the 2006 TRED (http://www.epa.gov/
oppsrrd1/REDs/ethylene_oxide_tred.pdf) and the 2008 RED (http://
www.epa.gov/oppsrrd1//REDs/ethylene-oxide-red.pdf) for ETO. In the 2008 
RED, the Agency addressed occupational risk concerns that were the 
focus of the Special Review. During the reregistration process EPA 
conducted a public, intensive review of ETO risks and benefits to 
determine whether or not ETO registrations meet the FIFRA standard for 
registration. The Agency determined that the benefits of ETO use 
outweigh the occupational risks associated with its use provided that 
the risk mitigation measures outlined in the RED are adopted and label 
amendments are made to reflect those measures. The final risk 
management decision regarding the risk to workers exposed to ETO was 
completed with the 2008 RED. A detailed description of the rationale 
and supporting documents can be found in http://www.regulations.gov 
under EPA-HQ-OPP-2005-0203. As described above and in the 2008 RED, 
concerns were addressed under FIFRA and no further action is required 
at this time. Because the risks that were the basis of the Special 
Review have been evaluated and the Agency has made a determination 
under FIFRA, as outlined above, the Agency is proposing to terminate 
the Special Review of ETO.

B. What is the Agency's Authority for Taking this Action?

    A pesticide product may be sold or distributed in the United States 
only if it is registered or exempt from registration under the Federal 
Insecticide, Fungicide and Rodenticide Act (FIFRA) as amended (7 U.S.C. 
136 et seq.). Before a product can be registered it must be shown, 
among other things, that it can be used without causing ``unreasonable 
adverse effects on the environment,'' FIFRA section 3(c)(5). The term 
unreasonable adverse effects on the environment means:
    (1) Any unreasonable risk to man or the environment, taking into 
account the economic, social, and environmental costs and benefits of 
the use of any pesticide; or
    (2) A human dietary risk from residues that result from a use of a 
pesticide in or on any food inconsistent with the standard under 
section 408 of the Federal Food, Drug and Cosmetic Act FIFRA section 
2(bb).
    The burden of proving that a pesticide meets this standard for 
registration is, at all times, on the proponent of initial or continued 
registration. If at any time the Agency determines that a pesticide no 
longer meets this standard, the Administrator may cancel this 
registration under section 6 of FIFRA.
    The Special Review process provides a mechanism to permit public 
participation in EPA's deliberations prior to issuance of any Notice of 
Final Determination pursuant to a Special Review describing the 
regulatory action which the Administrator has selected. The Special 
Review process, which was previously called the Rebuttable Presumption 
Against Registration (RPAR) process, is set forth in 40 CFR part 154, 
published in the Federal Register of November 27, 1985 (50 FR 49015). 
The purpose of this process is to help the Agency determine whether to 
initiate procedures to cancel, deny, or

[[Page 64320]]

reclassify registration of a pesticide product because uses of that 
product may cause unreasonable adverse effects on the environment, in 
accordance with FIFRA.
    Prior to formal initiation of a Special Review, a preliminary 
notification is sent to registrants and applicants for registration 
pursuant to 40 CFR 154.21 announcing that the Administrator may 
initiate a Special Review of a pesticide use. Registrants and 
applicants for registration are allowed 30 days from receipt of the 
notification to comment on the Agency's preliminary notification that 
it may commence a Special Review.
    If the Agency determines, after issuance of a notification pursuant 
to 40 CFR 154.21, that it will initiate a Special Review, 40 CFR 
154.25(c) requires the Administrator to publish a Notice of Special 
Review in the Federal Register. To conclude the Special Review after a 
Special Review has been initiated, 40 CFR 154.31 requires the 
Administrator to first publish a Notice of Preliminary Determination in 
the Federal Register. This notice concerning ETO is being issued 
pursuant to 40 CFR 154.31.
    That regulation requires the Administrator to respond to all 
significant comments received on the Notice of Special Review and, 
among other things, make a preliminary determination of whether any of 
the applicable risk criteria have been satisfied. Finally, after 
receipt and evaluation of comments on the Notice of Preliminary 
Determination, 40 CFR 154.33 requires that the Administrator publish in 
the Federal Register a Notice of Final Determination, including the 
reasons for the determination.
