Start Preamble

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Notice.

SUMMARY:

This notice announces the availability of EPA's draft human health and ecological risk assessments for the registration review of clethodim, hydrogen cyanamide, flutolanil, fosetyl-aluminum, hexaflumuron, and piperalin, and opens a public comment period on these documents. 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, the pesticide can perform its intended function without unreasonable adverse effects on human health or the environment. As part of the registration review process, the Agency has completed draft risk assessments for each of the subject chemicals and is making them available for public comment. After reviewing comments received during the public comment period, EPA will issue a revised risk assessment, explain any changes to the draft risk assessment, and respond to comments and may request public input on risk mitigation. 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.

DATES:

Comments must be received on or before May 28, 2014.

To help address potential environmental justice issues, the Agency seeks information on any groups or segments of the population who, as a result of their location, cultural practices, or other factors, may have atypical or disproportionately high and adverse human health impacts or environmental effects from exposure to the pesticides discussed in this document, compared to the general population.Start Printed Page 17537

II. Authority

EPA is conducting its registration review of the pesticides identified in this document pursuant to section 3(g) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Procedural Regulations for Registration Review at 40 CFR part 155, subpart C. Section 3(g) of FIFRA provides, among other things, that the registrations of pesticides are to be reviewed every 15 years. Under FIFRA, a pesticide product may be registered or remain registered only if it meets the statutory standard for registration given in FIFRA section 3(c)(5). When used in accordance with widespread and commonly recognized practice, the pesticide product must perform its intended function without unreasonable adverse effects on the environment; that is, without any unreasonable risk to man or the environment, or a human dietary risk from residues that result from the use of a pesticide in or on food.

III. Registration Reviews

A. What action is the agency taking?

As directed by FIFRA section 3(g), EPA is reviewing the pesticide registration for clethodim, hydrogen cyanamide, flutolanil, fosetyl-aluminum, hexaflumuron, and piperalin to ensure that they continues to satisfy the FIFRA standard for registration—that is, that these pesticides can still be used without unreasonable adverse effects on human health or the environment.

Pursuant to 40 CFR 155.53(c), EPA is providing an opportunity, through this notice of availability, for interested parties to provide comments and input concerning the Agency's draft human health and ecological risk assessments for clethodim, hydrogen cyanamide, flutolanil, fosetyl-aluminum, hexaflumuron, and piperalin. Such comments and input could address, among other things, the Agency's risk assessment methodologies and assumptions, as applied to the draft risk assessments.

The Agency will consider all comments received during the public comment period and make changes, as appropriate, to the draft human health and ecological risk assessments. EPA will then issue a revised risk assessment, explain any changes to the draft risk assessment, and respond to comments. In the Federal Register notice announcing the availability of the revised risk assessment, if the revised risk assessment indicates risks of concern, the Agency may provide a comment period for the public to submit suggestions for mitigating the risk identified in the revised risk assessment before developing a proposed registration review decision. At present, EPA is releasing registration review draft risk assessments for the pesticide cases identified in the following table and further described below.
