II. Background

A. What Action is the Agency Taking?

On February 24, 1988, the Agency published a Notice of Special Review Position Document 1 (PD 1) for pesticide products containing DDVP based on concerns for cancer, cholinesterase inhibition, and liver effects (53 FR 5542). On September 28, 1995, the Agency published a Notice of Preliminary Determination to Cancel Certain Registrations and a Draft Notice of Intent to Cancel (PD 2/3) (60 FR 50337). In the 1995 PD 2/3, the Agency determined that exposure to DDVP from the registered uses posed a carcinogenic risk of concern as well as risks of concern for cholinesterase inhibition. However, with respect to liver effects, the Agency determined that this Start Printed Page 72710endpoint was no longer of regulatory concern. Since the initiation of Special Review and publication of the PD 2/3, additional data have become available. Based in part on these data, the Agency has changed its assessment of some of the risks associated with DDVP, and modified the terms and conditions of DDVP registrations, accordingly. Moreover, during the recently concluded reregistration process for DDVP, EPA conducted an intensive and public review of whether DDVP registrations meet the FIFRA standard for registration, culminating in the Agency's 2006 Reregistration Eligibility Decision (RED) for DDVP. Through the reregistration processes the Agency resolved remaining concerns regarding cancer and cholinesterase effects. Accordingly, EPA has revised its assessment of DDVP since the time when the PD 1 and the PD 2/3 were published, respectively. Based on the RED, requested label amendments, and the voluntary cancellation of uses by the registrant pursuant to section 6(f) of FIFRA, EPA has determined that the risks that were the basis of the Special Review are no longer of concern. Therefore, on September 26, 2007, EPA announced its preliminary determination to terminate the Special Review of DDVP. The Agency did not receive any comments in response to its preliminary determination. This notice announces EPA's final determination to terminate the Special Review of DDVP. To the extent that the Agency further revises its assessment of DDVP, it will do so outside of the Special Review context.

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 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” is defined in FIFRA section 2(bb) as “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.” 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 describing the regulatory action which the Administrator has selected. The Special Review process, which was previously called the Rebuttable Presumption Against Registration (RPAR), is described in 40 CFR part 154, published in the Federal Register of November 25, 1985 (50 FR 49015). The purpose of this process is to determine whether some or all registrations of a particular active ingredient or ingredients meet the FIFRA standard for registration, or whether amendment of the terms and conditions of registration or cancellation of portions or all of the registrations is appropriate.

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 Agency is considering commencing a Special Review. Registrants and applicants for registration are allowed 30 days from receipt of the notification to comment on the Agency's proposal to 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 a 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.

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. This Notice is being issued pursuant to 40 CFR 154.33.
