Fenoxycarb, Sodium Tetrathiocarbonate, and Temephos; Registration Review Proposed Decisions; Notice of Availability


Environmental Protection Agency (EPA).




This notice announces the availability of EPA's proposed registration review decisions for the pesticides listed in the table in Unit II.A. and opens a public comment period on the proposed decisions. 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.


Comments must be received on or before July 5, 2011.

II. Background

A. What action is the Agency taking?

In accordance with 40 CFR 155.58, this notice announces the availability of EPA's proposed registration review decisions for the pesticides shown in the following table, and opens a 60-day public comment period on the proposed decisions.

Fenoxycarb is an O-ethyl carbamate derivative insecticide used to control fire ants and big-headed ants on turf, home lawns, agricultural areas, non-agricultural areas, horse farms, and ornamental nursery stock, among other areas. Fenoxycarb is also used to control a variety of insects in greenhouses in a total release fogger product.

Sodium tetrathiocarbonate is a soil fumigant used for the management of nematodes and phytophthora root rot, oak root fungus, and phylloxera. It is registered for use on grapes, citrus, almonds, peaches, prunes, and plums only in the states of Arizona, California, Oregon, and Washington.

Temephos is a non-systemic organophosphate insecticide which is applied to standing water, shallow ponds, lakes, woodland pools, tidal waters, marshes, swamps, waters high in organic content, highly polluted water, catch basins (and similar areas where mosquitoes may breed), stream margins, and intertidal zones of sandy beaches. Target pests include aquatic larvae of mosquitoes, midges, gnats, punkies, and sandflies.

Sodium Tetrathiocarbonate, Case No. 7009EPA-HQ-OPP-2007-1084Katherine St. Clair, (703) 347-8778,
Temephos, Case No. 0006EPA-HQ-OPP-2008-0444Katherine St. Clair, (703) 347-8778,

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 fenoxycarb, sodium tetrathiocarbonate, and temephos Preliminary Work Plans and Final Work Plans for registration review, the Agency had intended to revise the existing risk assessments. However, after the publication of the Final Work Plans, 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 fenoxycarb, sodium tetrathiocarbonate, and temephos product registrations from the registrants of these pesticides. After a 30-day comment period, the EPA granted the voluntary cancellation requests, establishing effective cancellation dates for all of the products registered for use in the United States containing the active ingredient, fenoxycarb on December 31, 2012 (December 30, 2010, 75 FR 82387) (FRL-8854-8), sodium tetrathiocarbonate on February 25, 2011 (February 25, 2011, 76 FR 10587) (FRL-8863-4), and temephos on December 31, 2015 (February 25, 2011, 76 FR 10587) (FRL-8863-4).

Following public comment, the Agency will issue final registration review decisions for products containing the pesticides listed in the table in Unit II.A.

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 the Federal Insecticide, Fungicide, and Rodenticide Act (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 inADDRESSES, and must be received by EPA on or before the closing date. These comments will become part of the docket for the pesticides included in the table in Unit II.A. 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 final 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: Links to earlier documents related to the registration review of these pesticides are provided at:

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.
