II. Background

A. What Action is the Agency Taking?

    EPA is making available the human health and environmental fate and
effects risk assessments for chloropicrin. Chloropicrin is a non-
selective pre-plant soil fumigant with fungicidal, herbicidal,
insecticidal, and nematicidal properties. Chloropicrin is also used in
combination with other soil fumigants and as a warning agent for other
soil fumigants such as methyl bromide and telone (1,3-dichloropropene)
and structural fumigations using sulfuryl flouride. Chloropicrin is
primarily used for pre-plant soil uses for agricultural crops and
greenhouses. However, chloropicrin is also used for fumigations of
empty grain and storage bins, tree replant sites, and wood telephone
poles and timber. The Agency developed these risk assessments as part
of its public 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 Food Quality
Protection Act of 1996 (FQPA).
    An estimated 5-9 million pounds of chloropicrin is applied
annually. Crops on which over a million pounds are used annually
include tobacco (3.6 million pounds), tomatoes (1.7 million pounds),
and strawberries (1.4 million pounds). Strawberries (20 percent),
tobacco (15 percent), and tomatoes (10 percent) are also the crops with
the highest percentage of their overall acreage treated. Almost all of
the pre-plant soil fumigation uses of chloropicrin occur in combination
with either methyl bromide or telone.
    Plant metabolism and environmental fate studies demonstrate that
chloropicrin is degraded in both anaerobic and aerobic soil to carbon
dioxide which is subsequently taken up by the plant. Therefore, the use
of chloropicrin as a pre-plant soil fumigant is considered to be a non-
food use and food tolerances are not required.
    EPA is providing an opportunity, through this notice, for
interested parties to provide comments and input on the Agency's risk
assessments for chloropicrin. Such comments and input could address,
for example, the availability of additional data to further refine the
risk assessments, or information about specific use practices for crops
that are produced using chloropicrin. For example, the following
information would be helpful to EPA in characterizing regional and crop
differences in use practices and possible effects on potential risk.
When providing this information to the Agency, consider providing
pictures or video footage to help clarify your comments.
    1. Crop.
    2. Fumigant use.
    3. Average acres grown per enterprise.
    4. Maximum acres fumigated per day.
    5. Percent of the acres grown that are fumigated.
    6. Typical application rate (lb a.i./acre).
    7. Minimum application rate used (lb a.i./acre)(for high pest
pressure situations).
    8. Time of year that soil is fumigated.
    9. Fumigation cycle (every crop cycle, 1 time/year, 1 time/2 years).
    10. Target pests (by category or specific pests).
    11. Method of application (e.g., chemigation, soil injection,
specific equipment used, etc.).
    12. Methods or actions taken to reduce emissions (polyethylene
tarps or soil cap).
    13. Could high-density polyethylene (HDPE) or high barrier tarps be
used on this crop?
    14. Time between treatment and next production activity (e.g., time
until planting).
    15. Typical crops following the fumigated crop (only if they
benefit from the fumigation).
    16. Regulatory restrictions in your area on this fumigant or an
alternative fumigant (such as weather restrictions).
    17. Soil restrictions on this fumigant or an alternative fumigant.
    18. Any restrictions or concerns about minimum soil temperature,
hilly terrain, etc.
    19. Best available alternative (another fumigant or strategy such
as leaving land fallow, etc.).
    20. Could the use of different soil fumigants be alternated (e.g.,
metam sodium followed by (1,3-D)? Specify how.
    21. Yield or quality impacts that are likely to result from moving
to the best available alternative (i.e., change in commodity price or
grade).
    22. Would moving to the next best alternative impact key market
windows? How?
    23. Cost per acre of active ingredient.
    24. Cost per acre of other fumigation inputs (e.g., tarps and
equipment).
    25. Is there a crop budget available for your area and crop?
    26. Do you know of any other contacts or other sources of
information for this crop who could provide information on acreage,
prices, pests, etc.?
    27. Are there non-chemical alternatives that can be used in place
of fumigants? Describe use.
    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 atypical, unusually high exposure
to chloropicrin, 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.
EPA plans to review chloropicrin through the full, 6-Phase public
participation process.
    Comments should be limited to issues raised within the risk
assessment(s) 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 chloropicrin.
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) of FIFRA as amended 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,'' before calling in product
specific data on individual end-use products and either reregistering
products or taking other ``appropriate regulatory action.''
