Environmental Protection Agency (EPA).
This notice announces the availability of EPA's cumulative risk assessment for the organophosphate group of pesticides and opens a public comment period on this document and other support documents. As required by the Food Quality Protection Act (FQPA), a cumulative risk assessment, which evaluates exposures based on a common mechanism of toxicity, was conducted to evaluate the risk from food, drinking water, residential, and other non-occupational exposures resulting from registered uses of organophosphate pesticides. The organophosphate group includes over 30 pesticides including acephate, azinphos-methyl (AZM), bensulide, chlorethoxyfos, chlorpyrifos, chlorpyriphos-methyl, diazinon, dichlorvos (DDVP), dicrotophos, dimethoate, disulfoton, ethoprop, fenamiphos, fenthion, fosthiazate, malathion, methamidophos, methidathion, methyl-parathion, mevinphos, naled, omethoate, oxydemeton-methyl, phorate, phosalone, phosmet, phostebupirim, pirimiphos-methyl, profenofos, terbufos, tetrachlorvinphos, tribufos, and trichlorfon. Several organophosphate pesticides, however, were not incorporated into the cumulative risk assessment because no dietary, drinking water, or residential human exposure to these pesticides is anticipated from any of the currently registered uses.

A. What Action is the Agency Taking?
EPA is making available the completed cumulative risk assessment for the organophosphate pesticides. The Agency developed this risk assessment as part of its ongoing process for making pesticide reregistration eligibility and tolerance reassessment decisions. Through these programs, EPA is ensuring that pesticides 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 FQPA.
Section 408(b)(2)(D)(v) of the FFDCA directs the Agency to consider available information on the cumulative risk from substances sharing a common mechanism of toxicity. The Agency determined in 1999 that the organophosphate pesticides share a common mechanism of toxicity, cholinesterase inhibition. The organophosphates have been among EPA's highest priority pesticides for review under FQPA.
In developing the organophosphate cumulative risk assessment and underlying methodologies, EPA consulted with the FIFRA Scientific Advisory Panel numerous times, seeking expert review, advice, and recommendations at each major step of the process. The Agency also met with several of its advisory committees to obtain input from a broad spectrum of stakeholders representing the pesticide industry, environmental and public interest groups, growers, academia, and others, including other federal and state regulatory agencies. EPA issued the Preliminary Organophosphate Cumulative Risk Assessment for public comment in December 2001, and presented the cumulative assessment at a Technical Briefing for the public in January 2002. The Agency released the Revised Organophosphate Cumulative Risk Assessment for public comment in June 2002. The Organophosphate Cumulative Risk Assessment (2006 update) is considered an addendum to the June 2002 assessment, and includes improvements and refinements in assessing the cumulative risks of the organophosphate pesticides. The previous versions of the Organophosphate Cumulative Assessment may be accessed on the EPA website at http://www.epa.gov/pesticides/cumulative.
EPA has concluded that the cumulative risks associated with the remaining uses of the organophosphate pesticides are below the Agency's level of concern. While completing reregistration eligibility and tolerance reassessment decisions for individual organophosphates, the Agency also evaluated the cumulative risk posed by this group. Although individual risk assessments were conducted for each of the organophosphate pesticides, several were not incorporated into the cumulative risk assessment because no dietary, drinking water, or residential human exposure is anticipated from any of the currently registered uses of these pesticides.
The Interim Reregistration Eligibility Decisions (IREDs) previously issued for a number of organophosphate pesticides are now considered final; the tolerance reassessment and reregistration eligibility process for these pesticides is complete. EPA has determined that the remaining/reassessed tolerances for these pesticides meet the FFDCA safety standard and that no further risk mitigation is necessary as a result of the organophosphate cumulative risk assessment.
EPA is providing an opportunity, through this notice, for interested parties to provide comments and input on the Agency's completed cumulative risk assessment for the organophosphates. Such comments and input could address the Agency's risk assessment methodologies and assumptions as applied to this cumulative assessment. The Agency will consider all comments received, and make changes, if appropriate, to the organophosphate cumulative risk assessment.
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 Start Printed Page 43742policies. 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, unusually high exposure to organophosphate pesticides, compared to the general population.
EPA is applying the principles of public participation to all pesticides undergoing reregistration and tolerance reassessment. The Agency's Pesticide Tolerance Reassessment and Reregistration; Public Participation Process, published in the Federal Register on May 14, 2004, (69 FR 26819) (FRL-7357-9) explains that in conducting these programs, EPA is tailoring its public participation process to be commensurate with the level of risk, extent of use, complexity of issues, and degree of public concern associated with each pesticide. The organophosphate pesticides have had extensive opportunities for public comment as part of their reregistration and tolerance reassessment process.
Comments should be limited to issues raised within the organophosphate cumulative risk assessment and associated documents. Failure to comment on any such issues as part of this opportunity will not limit a commenter's opportunity to participate in any later notice and comment processes on this matter. All comments should be submitted using the methods in ADDRESSES, and must be received by EPA on or before the closing date. Comments will become part of the Agency Docket for the organophosphate cumulative risk assessment. 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 4(g)(2)(A) of FIFRA, as amended, requires the Administrator to make “a determination as to the eligibility for reregistration (i) for all active ingredients subject to reregistration under this section for which tolerances or exemptions from tolerances are required under the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 301 et seq.), not later than the last date for tolerance reassessment established under section 408(q)(1)(C) of that Act (21 U.S.C. 346a((q)(1)(C))...”
Section 408(q) of the FFDCA, 21 U.S.C. 346a(q), requires EPA to review tolerances and exemptions for pesticide residues in effect as of August 2, 1996, to determine whether the tolerance or exemption meets the requirements of section 408(b)(2) of (c)(2) of FFDCA. This review is to be completed by August 3, 2006. A tolerance or exemption meets the requirements of section 408(b)(2) or (c)(2), respectively, if “the Administrator determines the pesticide chemical residue is safe,” i.e., “that there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue, including all anticipated dietary exposures and all other exposures for which there is reliable information.” 21 U.S.C. 346a(b)(2)(A), and (c)(2)(A). In making this safety finding, FFDCA requires the Administrator to consider, among other factors, “available information concerning the cumulative effects of such residues and other substances that have a common mechanism of toxicity...” 21 U.S.C. 346a(b)(2)(D)(v), and (c)(2)(B).Start List of Subjects
