Urea Sulfate Registration Review; Draft Ecological Risk Assessment; Notice of Availability

Summary:

This notice announces the availability of EPA’s draft ecological risk assessment for the registration review of urea sulfate and opens a public comment period on this document. 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 a comprehensive draft ecological risk assessment for urea sulfate uses, including a determination that urea sulfate uses will have no effect on federally listed threatened or endangered species or their designated critical habitat. 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 before completing a proposed registration review decision for urea sulfate. 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.

I. General Information

A. Does this Action Apply to Me?

This action is directed to the public in general, and may be of interest to a wide range of stakeholders, including environmental, human health, farm worker, and agricultural advocates; the chemical industry; pesticide users; and members of the public interested in the sale, distribution, or use of pesticides. Since others also may be interested, the Agency has not attempted to describe all the specific entities that may be affected by this action. If you have any questions regarding the applicability of this action to a particular entity, consult the chemical review manager listed under FOR FURTHER INFORMATION CONTACT.

B. What Should I Consider as I Prepare My Comments for EPA?

1. Submitting CBI. Do not submit this information to EPA throughregulations.gov or e-mail. Clearly mark the part or all of the information that you claim to be CBI. For CBI information in a disk or CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM as CBI and then identify electronically within the disk or CD-ROM the specific information that is claimed as CBI. In addition to one complete version of the comment that includes information claimed as CBI, a copy of the comment that does not contain the information claimed as CBI must be submitted for inclusion in the public docket.

3. Environmental justice. EPA seeks to achieve environmental justice, the fair treatment and meaningful involvement of any group, including minority and/or low income populations, in the development, implementation, and enforcement of environmental laws, regulations, and policies. 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 pesticide(s) discussed in this document, compared to the general population.

II. Authority

EPA is conducting its registration review of urea sulfate 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 urea sulfate to ensure that it continues to satisfy the FIFRA standard for registration— that is, that urea sulfate can still be used without unreasonable adverse effects on human health or the environment. Urea sulfate is a herbicide used as a desiccant on cotton as a cotton harvest aid/defoliant. EPA has completed a comprehensive draft ecological risk assessment, including an endangered species assessment, for all urea sulfate uses and is announcing the availability of the draft ecological risk assessment.

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 ecological risk assessment for urea sulfate. Such comments and input could address, among other things, the Agency’s risk assessment methodologies and assumptions, as applied to the draft risk assessment for the registration review of urea sulfate. The Agency will consider all comments received during the public comment period and make changes, as appropriate, to the draft ecological risk assessment. 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 on urea sulfate. As described in detail in the Urea Sulfate Summary Document, see docket ID number EPA-HQ-OPP-2007-0202, the Agency believes that the human health risk assessments completed prior to registration review are adequate, and there are no dietary or occupational risks that exceed the Agency’s level of concern. Thus, no additional human health data are needed for the registration review of urea sulfate.

1. Other related information. Additional information on urea sulfate is available on the Pesticide Registration Review Status webpage for this pesticide, http://www.epa.gov/oppsrrd1/registration_review/urea_sulfate/index.htm.Information on the Agency's registration review program and its implementing regulation is available at http://www.epa.gov/oppsrrd1/registration_review.

2. Information submission requirements. Anyone may submit data or information in response to this document. To be considered during a pesticide's registration review, the submitted data or information must meet the following requirements:

• To ensure that EPA will consider data or information submitted, interested persons must submit the data or information during the comment period. The Agency may, at its discretion, consider data or information submitted at a later date.

• The data or information submitted must be presented in a legible and useable form. For example, an English translation must accompany any material that is not in English and a written transcript must accompany any information submitted as an audiographic or videographic record. Written material may be submitted in paper or electronic form.

• Submitters must clearly identify the source of any submitted data or information.

• Submitters may request the Agency to reconsider data or information that the Agency rejected in a previous review. However, submitters must explain why they believe the Agency should reconsider the data or information in the pesticide's registration review.

As provided in 40 CFR 155.58, the registration review docket for each pesticide case will remain publicly accessible through the duration of the registration review process; that is, until all actions required in the final decisionon the registration review case have been completed.
