# ACTION: 

Notice.

# SUMMARY: 

This notice announces the availability of EPA's proposed registration review decision for the pesticide disulfoton and opens a public comment period on the proposed decision. Registration review is EPA's periodic review of pesticide registrations to ensure that each pesticide continues to satisfy the statutory standard for registration, that is, that the pesticide can perform its intended function without unreasonable adverse effects on human health or the environment. Through this program, EPA is ensuring that each pesticide's registration is based on current scientific and other knowledge, including its effects on human health and the environment.

## II. Background

### A. What Action is the Agency Taking?

Pursuant to 40 CFR 155.58, this notice announces the availability of EPA's proposed registration review decision for the pesticide, disulfoton, case number 0102, and opens a 60-day public comment period on the proposed decision. Disulfoton is an organophosphate insecticide registered for use on asparagus, beans, broccoli, Brussels sprouts, cabbage, cauliflower, cotton, coffee beans, lettuce, radish grown for seed, Christmas trees, Easter lilies, and residential ornamentals. 

The registration review docket for a pesticide includes earlier documents related to the registration review of the case. For example, the review opened with the posting of a Summary Document, containing a Preliminary Work Plan, for public comment. A Final Work Plan was posted to the docket following public comment on the initial docket. 

                    As stated in the Disulfton Preliminary Work Plan for registration review, the Agency had intended to revise the existing risk assessments for disulfoton. However, after the publication of the Disulfton Preliminary Work Plan, pursuant to section 6(f)(1) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), as amended, the Agency announced receipt of requests to voluntarily cancel all disulfoton product                           ( print page 54806)                        registrations and then granted the voluntary cancellation requests, establishing effective cancellation dates (FRL-8437-1); (74 FR 48551) for all of the products registered for use in the United States containing the active ingredient, disulfoton. The Agency described the impact of the cancellations on the registration review of disulfoton in the Final Work Plan, which was issued on October 1, 2009. Due to the cancellation order issued affecting all disulfoton product registrations in the United States, the Agency has found that it is not necessary to conduct new risk assessments for disulfoton and is therefore issuing a proposed decision pursuant to 40 CFR 155.53(c)(2) and 40 CFR 155.58. The Agency believes that mitigation measures put into effect on product labeling through the reregistration process are adequate to protect human health and the environment until existing stocks of disulfoton are exhausted. This proposed registration review decision is described in more detail in the Disulfoton Proposed Registration Review Decision, available in the disulfoton docket.                

Following public comment, the Agency will issue a registration review final decision for products containing disulfoton.

The registration review program is being conducted under congressionally mandated time frames, and EPA recognizes the need both to make timely decisions and to involve the public. Section 3(g) of FIFRA, as amended, required EPA to establish by regulation procedures for reviewing pesticide registrations, originally with a goal of reviewing each pesticide's registration every 15 years to ensure that a pesticide continues to meet the FIFRA standard for registration. The Agency's final rule to implement this program was issued in August 2006, and became effective in October 2006, and appears at 40 CFR part 155, subpart C. The Pesticide Registration Improvement Act of 2003 (PRIA) was amended and extended in September 2007. FIFRA, as amended by PRIA in 2007, requires EPA to complete registration review decisions by October 1, 2022, for all pesticides registered as of October 1, 2007.

                    The registration review final rule at 40 CFR 155.58(a) provides for a minimum 60-day public comment period on all proposed registration review decisions. This comment period is intended to provide an opportunity for public input and a mechanism for initiating any necessary amendments to the proposed decision. All comments should be submitted using the methods in                     **ADDRESSES**                    , and must be received by EPA on or before the closing date. These comments will become part of the docket for disulfoton. Comments received after the close of the comment period will be marked “late.” EPA is not required to consider these late comments.                

The Agency will carefully consider all comments received by the closing date and will provide a “Response to Comments Memorandum” in the docket. The registration review decision will explain the effect that any comments had on the decision and provide the Agency's response to significant comments.

                    Background on the registration review program is provided at:                     *http://www.epa.gov/​oppsrrd1/​registration_​review*. A link to earlier documents related to the registration review of disulfoton is provided at:                     *http://www.epa.gov/​oppsrrd1/​registration_​review/​reg_​review_​status.htm*.                 

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

Section 3(g) of FIFRA and 40 CFR part 155, subpart C, provide authority for this action.
