II. Background

A. What Action is the Agency Taking?

EPA is making available the human health risk assessment for iodomethane. Iodomethane is a new chemical proposed for use as a pre-plant fumigant to control soil borne pests including weed seeds, nematodes, insects, and diseases in fields intended for commercial production of strawberries, tomatoes, peppers, turf, ornamentals (flowers grown for cutting, bulbs, and nursery plants), trees and vines. The Agency developed this risk assessment as part of the registration decision process. EPA is ensuring that all new pesticides proposed for use meet current standards under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (FQPA).

The risk assessment for iodomethane addresses exposures to workers and the general population which are expected to occur primarily via inhalation. Dermal exposure is not expected due to the high vapor pressure of iodomethane. Potential general population exposures via inhalation are those in proximity to treated fields (i.e., bystanders). These exposure scenarios are plausible considering the volatility of fumigants, in general, and the potential for fumigant off-gassing into the air and transport off-site by winds to bystanders in proximity to treated fields. Exposures to iodomethane may be acute (less than 24 hours), short-term (one to thirty days), intermediate-term (one month to six months) or long-term in duration. Acute exposures have been quantitatively assessed because this duration is the key concern due to the anticipated use pattern of iodomethane, its emission profile and the nature of its toxicity. Additionally, for these same reasons, it is believed that the human health assessment of acute exposures are protective of other durations of exposure. Iodomethane is considered a nonfood use chemical, and a dietary risk assessment was not conducted. The general population may be exposed to iodomethane through drinking water. Therefore, a qualitative drinking water risk assessment was conducted, and no risks were identified from this potential source of exposure.

EPA is providing an opportunity, through this notice, for interested parties to provide comments and input on the Agency's risk assessment for iodomethane. Such comments and input could address, for example, the availability of additional data to further refine the risk assessments, such as meteorological data for probabilistic modeling purposes and projections for product use by major use regions, frequency or application parameters, etc., or could address the Agency's risk assessment methodologies and assumptions, air dispersion models, or physiologically-based pharmacokinetic models as applied to this specific pesticide.

EPA seeks to achieve environmental justice, the fair treatment and meaningful involvement of all people, regardless of race, color, national origin, or income, 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 potentially atypical, unusually high exposure to iodomethane, compared to the general population.

Comments should be limited to issues raised within the risk assessment and associated documents or to environmental justice issues discussed above. All comments should be submitted using the methods in Unit I. of the SUPPLEMENTARY INFORMATION, and must be received by EPA on or before the closing date. Comments will become part of the Agency Docket for iodomethane. Comments received after the close of the comment period will be marked “late.” EPA is not required to consider these late comments.

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

Section 3 of FIFRA directs that “the Administrator may by regulation limit the distribution, sale, or use in any State of any pesticide that is not registered under this Act and that is not the subject of an experimental use permit under section 5 or an emergency exemption under section 18.”
