Methyl Bromide Revised Risk Assessment for Uses in Enclosures, 
Chambers and Structural Food Processing/Storage Facilities; Notice of 
Availability and Solicitation of Risk Reduction Options

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: This notice announces the availability of EPA's revised risk 
assessment for the pesticide methyl bromide's uses in enclosures, 
chambers and structural food processing/storage facilities. In 
addition, this notice solicits public comment on risk reduction options 
for methyl bromide's commodity uses. The public is encouraged to 
suggest risk management ideas or proposals to address the risks 
identified. EPA is developing a Reregistration Eligibility Decision 
(RED) for uses in enclosures, chambers and structural food processing/
storage facilities of methyl bromide (i.e. uses that result in a food 
tolerance) through the full, 6-Phase public participation process that 
the Agency uses to involve the public in developing pesticide 
reregistration and tolerance reassessment decisions. Through these 
programs, EPA is ensuring that all pesticides meet current health and 
safety standards.

II. Background

A. What Action is the Agency Taking?

    EPA is making available the Agency's revised risk assessment for 
methyl bromide use in enclosures, chambers and structural food 
processing/storage facilities, initially issued for comment through a 
Federal Register notice published on July 13, 2005, 70 FR 40336, (FRL-
7721-3) a response to comments; and related documents for methyl 
bromide. EPA also is soliciting public comment on risk reduction 
options for methyl bromide's uses in enclosures, chambers and 
structural food processing/storage facilities and EPA's initial 
assessment of the impacts of these risk reduction options. EPA 
developed the risk assessment for methyl bromide 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).
    The risk assessment includes methyl bromide uses that have 
accompaning food residue tolerances such as post-harvest fumigation of 
food commodities in chambers at ports or specialized structural 
fumigations at food processing facilities. Although some methyl bromide 
uses such as fumigation of timber, wood products, and industrial 
equipment do not require a food residue tolerance, they have been 
included in this assessment since they are performed in similar 
facilities and were assessed with similar methods.
    EPA plans to release a revised assessment (Phase 5) for all other 
uses of methyl bromide, mainly soil fumigant applications, later this 
year. The Agency is delaying the soil fumigant component of methyl 
bromide reregistration in response to stakeholder comments that the 
risks, benefits, and risk management of soil fumigation uses of methyl 
bromide and its alternatives should be considered in the same general 
time frame. Alternatives currently in the reregistration process 
include metam sodium, dazomet, and chloropicrin. In particular, 
stakeholders have noted that chloropicrin is frequently applied in 
conjunction with methyl bromide and thus commenters have asserted that 
it makes sense to consider risk management strategies jointly for these 
chemicals. The Agency agrees with this logic and thus has separated the 
assessments so that risk management decisions can be made as 
expeditiously as feasible for all uses.
    EPA estimated the methyl bromide usage in the U.S. for 2004 based 
on information from the methyl bromide critical use exemption process, 
U.S. Department of Agriculture, Animal and Plant Health Inspection 
Service, and EPA proprietary sources. Based on these sources EPA 
estimates there was a total of 23 million pounds of methyl bromide used 
in the U.S. in 2004 with 3 million pounds used on commodities, food 
processing facilities, and food quarantine uses, and 20 million pounds 
used for all other uses, mainly pre-plant soil applications.
    Application rates for commodity fumigations can range from 1 to 20 
lb ai/1000 ft3 but most are in the 1 to 9 lb ai/1000 
ft3 range. Likewise, structural fumigations are in the 1 to 
9 lb ai/1000 ft3 range. For structural, commodity and other 
types of applications, an application rate of 9 lb ai/1000 
ft3 was used as the basis for risk assessment purposes.
    EPA is providing an opportunity, through this notice, for 
interested parties to provide risk management proposals or otherwise 
comment on risk management for methyl bromide. Regarding risks to 
humans from methyl bromide commodity uses, there are no aggregate 
dietary risks of concern resulting from acute and chronic exposures 
(food and water only). Risks of concern associated with the use of 
methyl bromide commodity uses are:
    1. Occupational exposures during treatment and aeration processes 
and;
    2. Bystander exposure during treatment and aeration processes. In 
targeting these risks of concern, the Agency solicits information on 
effective and practical risk reduction measures.
    EPA's Office of Atmospheric Programs (OAP) has also estimated the 
number of UV-related skin cancer incidents and deaths due to ozone 
depletion caused by methyl bromide's uses in enclosures, chambers, and 
structural food processing/storage facilities. OAP's assessment is also 
included in the docket for public comment. The Agency believes it is 
appropriate to consider these cancer risks as part of the 
reregistration process because the risks clearly result from use of 
methyl bromide products registered for use under FIFRA.
    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

[[Page 15730]]

with each pesticide. Due to its uses, risks, and other factors, methyl 
bromide is being reviewed through the full 6-Phase public participation 
process.
    All comments should be submitted using the methods in ADDRESSES, 
and must be received by EPA on or before the closing date. Comments and 
proposals will become part of the Agency Docket for methyl bromide. 
Comments received after the close of the comment period will be marked 
``late.'' EPA is not required to consider these late comments. After 
considering comments received, EPA will develop and issue for comment 
the methyl bromide RED.

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.''
    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) or (c)(2) of FFDCA. This review 
is to be completed by August 3, 2006.
