specific questions or organize comments by referencing a Code of 
Federal Regulations (CFR) part or section number.
    iii. Explain why you agree or disagree; suggest alternatives and 
substitute language for your requested changes.
    iv. Describe any assumptions and provide any technical information 
and/or data that you used.
    v. If you estimate potential costs or burdens, explain how you 
arrived at your estimate in sufficient detail to allow for it to be 
    vi. Provide specific examples to illustrate your concerns and 
suggest alternatives.
    vii. Explain your views as clearly as possible, avoiding the use of 
profanity or personal threats.
    viii. Make sure to submit your comments by the comment period 
deadline identified.

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 mevinphos 
tolerances at 40 CFR 180.157. Under section 408(f) of the Federal Food, 
Drug, and Cosmetic Act (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 
    1. A requirement that one or more persons submit to EPA a notice 
identifying the person(s) who commit to submit the data required in the 
    2. A description of the required data and the required reports 
connected to such data.
    3. An explanation of why the required data could not be obtained 
under section 3(c)(2)(B) of FIFRA or section 4 of TSCA.
    4. The required submission date for the notice identifying one or 
more interested persons who commit to submit the required data and the 
required submission dates for all the data and reports required in the 
order. (21 U.S.C. 346a(f)(1)(C)).
    EPA may by order modify or revoke the affected tolerances if any 
one of the following submissions is not made in a timely manner:
     A notice identifying one or more interested persons who 
commit to submit the data.
     The data itself.
     The reports required under a section 408(f) order are not 
submitted by the date specified in the order. (21 U.S.C. 346a(f)(2)).

III. Regulatory Background for Mevinphos

    Mevinphos is a contact/systemic insecticide-acaricide. It is not 
currently registered under FIFRA and may not be sold, distributed, or 
used in the United States. Mevinphos' FIFRA registration was canceled 
in 1994. However, 15 FFDCA tolerances remain for residues of mevinphos 
on the following commodities: Broccoli, cabbage, cauliflower, celery, 
cucumbers, grapes, lettuce, melons, peas, peppers, spinach, 
strawberries, summer squash, tomatoes, and watermelon (40 CFR 180.157). 
Since there are currently no domestic registrations for mevinphos, 
these tolerances are referred to as ``import tolerances.''
    Mevinphos is a member of a family of pesticides known as the 
organophosphates. EPA has concluded mevinphos and other organophosphate 
pesticides share a common mechanism of toxicity. As with other 
organophosphates, the principal toxic effects induced by mevinphos are 
related to its cholinesterase-inhibiting activity. It produces the 
associated clinical signs such as tremors, unsteady gait, decreased 
activity, salivation, disturbed balance in rats and rabbits, and 
decreased cholinesterase activity (plasma, brain) in rats and rabbits 
following acute, subchronic, and chronic oral exposure.
    In September 2000, EPA issued an Interim Tolerance Reassessment 
Eligibility Decision (ITRED) for mevinphos in connection with its 
obligation under the Food Quality Protection Act of 1996 (FQPA), to 
evaluate whether all 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 ITRED, EPA concluded that the risks of mevinphos 
when evaluated in isolation from other organophosphates met the revised 
safety standard in FFDCA section 408. This conclusion 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.
    The ITRED called attention to several data gaps for mevinphos 
    1. A developmental neurotoxicity (DNT) study in rats (with expanded 
protocol to extend the postnatal treatment period and to measure 
cholinesterase inhibition in offspring) as was required for all 
organophosphate pesticides.
    2. Various studies evaluating mevinphos residue levels on treated 
crops. EPA noted that it would be taking steps to require the 
submission of this data. Subsequently, the manufacturer of mevinphos 
submitted residue data for grapes and frozen storage stability data for 
broccoli, cucumbers, lettuce, tomatoes, and strawberries. However, the 
registrant has not submitted a DNT study or residue data for the 
remaining imported commodities.
    Under section 3(g) of FIFRA and implementing regulations, EPA has

[[Page 44183]]

established a review program for pesticides registered under FIFRA. The 
goal of that program is 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 mevinphos is not registered under FIFRA, EPA will be re-
examining mevinphos with the other registered organophosphates because 
of the organophosphates shared mechanism of toxicity.
    In re-examining mevinphos, EPA has identified several studies noted 
in the ITRED as data gaps for which data have not been submitted and 
one new regulatory data requirement for which a study is needed. These 
data are necessary to support the continuation of mevinphos tolerances 
and are listed below.

 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 tolerances for mevinphos which are codified at 40 CFR 180.157. 
Accordingly, EPA proposes to issue a final order requiring the 
submission of the following data:
    1. Comparative Cholinesterase Assay (Test Guideline 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 DCI 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 
to OPP. 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 mevinphos 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 
mevinphos is not required at this time.
    2. Immunotoxicity Study (Test Guideline 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).
    The Immunotoxicity Test Guideline (Harmonized Guideline 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 
    3. Directions for Use (Test Guideline 860.1200)
    Rationale. The Agency needs use directions, which appear on the 
Mexico label(s).
    4. Crop Field Trials (Test Guideline 860.1500) - (broccoli, 
cabbage, cauliflower, celery, grapes, lettuce, peas, peppers, spinach, 
strawberries, summer squash, and tomatoes.)
    Rationale. Field trials are required for each commodity/commodity 
group according to guidelines that 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 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 the Federal Register, a 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 
number and location of field trials.
    5. Processing Study (tomatoes) (Test Guideline 860.1520)
    Rationale. Processing studies are required to determine whether 
residues in raw commodities may be expected to degrade or concentrate 
during food processing. If residues concentrate in a processed 
commodity, a food or feed additive tolerance must be established. If 
residues do not concentrate in a processed commodity, the tolerance for 
the raw agricultural commodity applies to all processed food or feed 
derived from it.

B. Persons who Commit to Submit the Required Data

    After this 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 mevinphos in the Federal Register. If 
EPA issues such an order, persons who are interested in the 
continuation of the mevinphos tolerances must notify the Agency by 
completing and submitting the required ``Sec. 408(f) Order Response'' 
form (available in the docket) within 90 days after publication of the 
final order in the Federal Register.
    The ``Sec. 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:
    i. Develop new data.
    ii. Submit an Existing Study -- submit existing data not 
submitted previously to the Agency by anyone,
    iii. Upgrade a Study - submit or cite data to upgrade a study 
classified by EPA as partially acceptable and upgradable,
    iv. Cite an Existing Study - cite an existing study that EPA 
classified as acceptable or an existing study that has been 
submitted but not reviewed by the Agency.

C. Required Dates for Submission of Data/Reports

    The table below 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 the Federal Register of the 
final order.

D. Failure to Submit

    If the Agency does not receive a Sec. 408(f) Response Form 
identifying a person who agrees to submit the required data within 90 
days after publication of the final order, EPA will proceed to revoke 
the mevinphos tolerances at 40 CFR 180.157. Such revocation order is 
subject to the objection and hearing procedure 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 mevinphos tolerances include, but are not limited to the 
    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.
