Start Preamble

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Notice.

SUMMARY:

This notice constitutes the Agency's report on the Food Quality Protection Act (FQPA) tolerance reassessment progress and risk management decision for chlorpropham, announces the Agency's decision, and releases the human health risk assessment and related documents supporting this decision to the public. This notice of tolerance reassessment for chlorpropham starts the 30-day public comment period during which the public is invited to submit comments on the Agency's “Report of the FQPA Tolerance Reassessment Progress and Risk Management Decision (TRED)” for chlorpropham. If any comment causes the Agency to revise its decision on tolerance reassessment for chlorpropham, the Agency will publish a notice of its amendment in the Federal Register. The Agency's reassessment of dietary risk, including public exposure through food and drinking water as required by the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by FQPA, indicate that dietary risk from stored potatoes treated with chlorpropham per se, poses no risk concerns within the limits of the reassessed tolerances associated with chlorpropham use on potatoes.

DATES:

Comments must be submitted on or before October 18, 2002.

ADDRESSES:

Comments may be submitted by mail, electronically, or in person. Please follow the detailed instructions for each method as provided in Unit I. of the SUPPLEMENTARY INFORMATION.

II. Background

A. What Action is the Agency Taking?

This notice constitutes and announces the availability of the chlorpropham TRED. This decision has been developed as part of the public participation process that EPA and the U.S. Department of Agriculture (USDA) are using to involve the public in the reassessment of pesticide tolerances under FFDCA. EPA must review tolerances and tolerance exemptions that were in effect when FQPA was enacted in August 1996, to ensure that these existing pesticide residue limits for food and feed commodities meet the safety standard of the new law.

In reviewing these tolerances, the Agency must consider, among other things, aggregate risks from non-occupational sources of pesticide exposure, whether there is increased susceptibility to infants and children, and the cumulative effects of pesticides with a common mechanism of toxicity. The tolerances are considered reassessed once the safety finding has been made that aggregate risks are not of concern. A reregistration eligibility decision (RED) was completed for chlorpropham in April 1995, prior to FQPA enactment, and therefore needed an updated assessment to consider the provisions of the Act.

The FQPA requires that the Agency consider “available information” concerning the cumulative effects of a particular pesticide's residues and “other substances that have a common mechanism of toxicity.” The reason for consideration of other substances is due to the possibility that low-level exposures to multiple chemical substances that cause a common toxic effect by a common mechanism could lead to the same adverse health effect as would a higher level of exposure to any of the other substances individually. EPA did not perform a cumulative risk assessment as part of this reregistration review of chlorpropham, because the Agency has not determined if there are any other chemical substances that have a mechanism of toxicity common with that of chlorpropham. If EPA identifies other substances that share a common mechanism of toxicity with chlorpropham, then a cumulative risk assessment will be conducted that includes chlorpropham. Further, EPA is in the process of developing criteria for characterizing and testing endocrine disrupting chemicals and plans to implement an Endocrine Disruptor Start Printed Page 58797Screening Program. Chlorpropham will be reevaluated at that time and additional studies may be required.

Additionally, the Agency has evaluated the dietary risk associated with chlorpropham and has determined that provided the Special Local Need (SLN) registration for Easter lily bulb use is amended to reduce the maximum rate of application from 3.99 pounds active ingredient/acre to 2.0 pounds active ingredient/acre, as agreed upon by stakeholders, there is a reasonable certainty that no harm to any population subgroup will result from aggregate exposure to chlorpropham when considering dietary exposure and all other non-occupational sources of pesticide exposure for which there is reliable information. Therefore, with this mitigation measure in place, 15 tolerances are now considered reassessed and 9 new tolerances will be established for residues of chlorpropham in/on raw agricultural commodities under section 408(q) of the FFDCA.

All registrants of pesticide products containing the active ingredient listed in this document have been sent the appropriate TRED document, and must respond to labeling requirements within 8 months of receipt. In addition, the Agency requests a response to the generic Data Call-In (DCI) letter from technical registrants within 90 days of receipt.

The reregistration program is being conducted under Congressionally-mandated time frames, and EPA recognizes both the need to make timely reregistration decisions and to involve the public. All comments received within 30 days of publication of this Federal Register notice will be considered by the Agency. If any comment significantly impacts this TRED, the Agency will amend its decision by publishing a Federal Register notice.

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

The legal authority for this TRED falls under FIFRA, as amended in 1988 and 1996. Section 4(g)(2)(A) of FIFRA directs that, after submission of all data concerning a pesticide active ingredient, “the Administrator shall determine whether pesticides containing such active ingredient are eligible for reregistration,” and either reregistering products or taking “other appropriate regulatory action.”
