II. FFDCA Data Call-In Authority
In this document, EPA proposes to issue an order requiring the submission of various data to support the continuation of the fenamiphos tolerances at 40 CFR 180.349. Under section 408(f) of FFDCA, 21 U.S.C. 346a(f), EPA is authorized to require, by order, submission of data “reasonably required to support the continuation of a tolerance” when such data cannot be obtained under the Data Call-In authority of section 3(c)(2)(B) of the Federal Insecticide, Fungicide, and Rodenticide Act (“FIFRA”), 7 U.S.C. 136a(c)(2)(B), or section 4 of the Toxic Substances Control Act (“TSCA”), 15 U.S.C. 2603. A section 408(f) Data Call-In order may only be issued following notice and a comment period of not less than 60 days.
A section 408(f) Data Call-In order must contain the following elements:
EPA may by order modify or revoke the affected tolerances if any one of the following submissions is not made in a timely manner:
III. Regulatory Background for Fenamiphos
Fenamiphos is an organophosphate nematicide/insecticide. It is not currently registered under FIFRA. Fenamiphos' last FIFRA registration was canceled in 2007. However, four FFDCA tolerances remain for residues of fenamiphos on the following commodities: Pineapples, grapes, raisins, and bananas (40 CFR 180.349). Since there are currently no domestic registrations for fenamiphos, these tolerances are referred to as “import tolerances.”
Fenamiphos is a member of a family of pesticides known as the organophosphates. EPA has concluded fenamiphos and other organophosphate pesticides share a common mechanism of toxicity. As with other organophosphates, the principal toxic effects induced by fenamiphos are related to its cholinesterase-inhibiting activity. In animal laboratory studies, it produces the associated clinical signs such as tremors, unsteady gait, decreased activity, salivation, and disturbed balance in rats and rabbits, and decreased cholinesterase activity (plasma, brain) in rats and rabbits following acute, subchronic, and chronic oral exposure.
In February 2002, EPA issued an Interim Reregistration Eligibility Decision (IRED) for fenamiphos. The IRED evaluated the potential human health and ecological risks associated with all registered uses of fenamiphos. In connection with its obligation under the Food Quality Protection Act of 1996 (FQPA), the Agency also evaluated whether all fenamiphos tolerances in existence at the time of the passage of FQPA met the revised safety standard that the FQPA adopted for FFDCA section 408. In the IRED, EPA concluded that the risks of fenamiphos when evaluated in isolation from other organophosphates met the revised safety standard in FFDCA section 408. Thisconclusion was labeled “interim,” however, because EPA had not yet completed a cumulative risk assessment for the organophosphates. In July 2006, EPA completed its cumulative risk assessment for the organophosphate pesticides finding that these tolerances met the revised safety standard.
In June 2010, in response to a registrant's interest in supporting tolerances for import purposes, the Agency completed a revised human health risk assessment for fenamiphos. As there are no domestic registrations for fenamiphos products, the assessment was limited to an evaluation of the potential dietary risk from exposure to fenamiphos residues in imported food commodities. This assessment utilized updated risk assessment methodologies from those that were used for the IRED's dietary assessment. The 2010 assessment concluded that potential exposure to fenamiphos residues in or on imported food commodities exceeds the Agency's level of concern.
The 2010 assessment identified several studies that were needed to verify the accuracy of the assumptions used in the Agency's evaluation of dietary exposure to imported commodities treated with fenamiphos or that were needed to meet a new data requirement. The necessary data include: A comparative chlolinesterase assay, residue data for grape, and an immunotoxicity study. These data requirements are discussed in detail in Unit IV.
Under section 3(g) of FIFRA and implementing regulations, EPA has established a review program for pesticides registered under FIFRA. The goal of that program is for there to be a periodic review of pesticide registrations every 15 years to ensure that the registrations satisfy FIFRA standards and are based on “current scientific and other knowledge regarding the pesticide.” (40 CFR 155.40(a)). EPA is in the preliminary stages of the registration review process for organophosphate pesticides. Although fenamiphos is not registered under FIFRA, EPA will be reexamining fenamiphos with the other registered organophosphates because of the organophosphates' shared mechanism of toxicity.
IV. Data Requirements
A. Required Data and Reports
Pursuant to FFDCA section 408(f), EPA has determined that additional data are reasonably required to support the continuation of the import tolerances for fenamiphos which are codified at 40 CFR 180.349. These data cannot be obtained under FIFRA section 3(c)(2)(B) because fenamiphos is not registered under FIFRA, and the data call-in authority under that section only extends to registered pesticides. These data cannot be obtained under TSCA because pesticides are excluded from coverage under that statute. 15 U.S.C. 2602(2)(B)(ii).
Accordingly, EPA proposes to issue a final order requiring the submission of the following data:
1. Comparative Cholinesterase Assay (870.6300). A protocol and a final report are required.
Rationale: As an organophosphate pesticide (OP), inhibition of acetylcholinesterase (AChE) is the critical effect for use in human health risk assessment. Many OPs were subject to a Data Call-In for the developmental neurotoxicity study (DNT). This Data Call-In also included the requirement for AChE inhibition data to evaluate comparative sensitivity in juvenile and adult rats. These data are most often collected in a study called the comparative cholinesterase assay (CCA). Since that time, CCA studies for more than 20 OPs have been submitted. Although for some OPs no difference in sensitivity has been observed in juvenile and adult animals, for many of the OPs, juveniles have been shown to be more sensitive. At this time, OPP has determined that a CCA is required for fenamiphos to evaluate the potential for increased sensitivity in juvenile animals compared with that of adult animals. Given that the AChE data provided in the CCAs have provided more sensitive results than DNT studies for the OPs, a DNT study for fenamiphos is not required at this time.
2. Immunotoxicity study (870.7800). A final report and protocol are required.
Rationale: This is a new data requirement under 40 CFR part 158 as a part of the data requirements for registration of a pesticide (food and non-food uses) and for establishment of a tolerance.
The Immunotoxicity Test Guideline (OPPTS 870.7800) prescribes functional immunotoxicity testing and is designed to evaluate the potential of a repeated chemical exposure to produce adverse effects (i.e., suppression) on the immune system. Immunosuppression is a deficit in the ability of the immune system to respond to a challenge of bacterial or viral infections such as tuberculosis (TB), Severe Acquired Respiratory Syndrome (SARS), or neoplasia. An immunotoxicity study for fenamiphos has not been submitted.
3. Crop field trials—grapes (860.1500). A final report is required.
Rationale: Field trials are required for each commodity/commodity group under 40 CFR part 158. These data are used to establish the legal maximum residue that may remain on food and to assess the risk posed by the pesticide residue. While residue data for fenamiphos use on grape is adequate to support several application methods, the Agency has not received data to support the current foliar use of fenamiphos on grape in Mexico.
EPA guidelines recommend that crop field trials be designed to take into account where the crop is grown and how much of the crop is grown. Field trials are required for each type of formulation because the formulation can have a significant effect on the magnitude of the pesticide residue left on the crop. Residue trials also need to represent the maximum application rate on the label and have a geographic distribution representative of the commodity/commodity group. On June 1, 2000 (65 FR 35069) (FRL-6559-3), EPA published in theFederal Registera Notice which provided detailed guidance on applying current U.S. data requirements for the establishment or continuance of tolerances for pesticide residues in or on imported foods. A copy of that Notice is available in the docket of this proposed order. That Notice contains instructions for determining the number and location of field trials.
B. Persons Who Commit To Submit the Required Data
After the 60-day comment period closes, the Agency will respond to comments, if appropriate, and may issue a final order requiring the submission of various data for fenamiphos in theFederal Register. If EPA issues such an order, persons who are interested in the continuation of the fenamiphos tolerances must notify the Agency by completing and submitting the required “Section 408(f) Order Response” form (available in the docket) within 90 days after publication of the final Order in theFederal Register.
The “Section 408(f) Order Response Form” requires the identification of persons who will submit the required data and lists the options available to support the required data:
1. Develop new data.
2. Submit an existing study—submit existing data not submitted previously to the Agency by anyone.
3. Upgrade a study—submit or cite data to upgrade a study classified by EPA as partially acceptable and upgradable.
4. Cite an existing study—cite an existing study that EPA classified asacceptable or an existing study that has been submitted but not reviewed by the Agency.
C. Required Dates for Submission of Data/Reports
The following table lists the time allocated for both the completion and submission of each study. The required submission date is calculated from the date of publication in theFederal Registerof the final order.
D. Failure To Submit
If the Agency does not receive a Section 408(f) Response Form identifying a person who agrees to submit the required data within 90 days after publication of the final order in theFederal Register, EPA will proceed to revoke the fenamiphos tolerances at 40 CFR 180.349. Such revocation order is subject to the objection and hearing procedures in FFDCA section 408(g)(2), but the only material issue in such a procedure is whether a submission required by the order was made in a timely fashion.
Additional events that may be the basis for modification or revocation of fenamiphos tolerances include, but are not limited to, the following:
1. No person submits on the required schedule an acceptable proposal or final protocol when such is required to be submitted to the Agency for review.
2. No person submits on the required schedule an adequate progress report on a study as required by the order.
3. No person submits on the required schedule acceptable data as required by the final order.
4. No person submits supportable certifications as to the conditions of submitted data, where required by order and where no other cited or submitted study meets the data requirements the study was intended to fulfill.
V. Statutory and Executive Order Reviews
As required by statute, this proposal to require submission of data in support of tolerances is in the form of an order and not a rule. (21 U.S.C. 346a(f)(1)(C)). Under the Administrative Procedures Act, orders are expressly excluded from the definition of a rule. (5 U.S.C. 551(4)). Accordingly, the regulatory assessment requirements imposed on rulemaking do not, therefore, apply to this action.
