B. What Should I Consider as I Prepare My Comments for EPA?

    1.  Submitting CBI. Do not submit this information to EPA through

[[Page 33085]]

www.regulations.gov or e-mail. Clearly mark the part or all of the 
information that you claim to be CBI. For CBI information in a disk or 
CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM as 
CBI and then identify electronically within the disk or CD-ROM the 
specific information that is claimed as CBI. In addition to one 
complete version of the comment that includes information claimed as 
CBI, a copy of the comment that does not contain the information 
claimed as CBI must be submitted for inclusion in the public docket. 
Information so marked will not be disclosed except in accordance with 
procedures set forth in 40 CFR part 2.
    2.  Tips for preparing your comments. When submitting comments, 
remember to:
    i. Identify the document by docket ID number and other identifying 
information (subject heading, Federal Register date and page number).
    ii. Follow directions. The Agency may ask you to respond to 
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 
reproduced.
    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. What Action is the Agency Taking?

    Under section 18 of the Federal Insecticide, Fungicide, and 
Rodenticide Act (FIFRA) (7 U.S.C. 136p), at the discretion of the 
Administrator, a Federal or State agency may be exempted from any 
provision of FIFRA if the Administrator determines that emergency 
conditions exist which require the exemption. U.S. Department of 
Agriculture, Animal and Plant Health Inspection Service (USDA/APHIS) 
has requested the Administrator to issue a specific exemption for the 
use of diflubenzuron on alfalfa to control grasshoppers and Mormon 
crickets. Information in accordance with 40 CFR part 166 was submitted 
as part of this request.
    As part of this request, the Applicant asserts that use 
diflubenzuron is requested to protect pollinators of Spalding's 
catchfly, a threatened plant species endemic to the proposed treatment 
area in Montana. The U.S. Fish and Wildlife Service's recovery plan for 
Spalding's catchfly recommends that grasshopper control programs avoid 
the use of broad spectrum insecticides (such as carbaryl and malathion) 
that will affect native bee species. Since diflubenzuron is not 
registered for use on alfalfa, current USDA/APHIS policy is to include 
a 500-foot buffer around these fields during application to insure no 
residues occur on alfalfa. Since the alfalfa fields are interspersed 
within the rangeland spray block, the resulting treatments will create 
several untreated areas that will allow grasshoppers to disperse from 
untreated alfalfa fields and buffer strips into previously treated 
areas and also damage untreated alfalfa hay.
    The Applicant proposes the use of diflubenzuron on 3,000 acres 
alfalfa in Montana to control grasshoppers and Mormon crickets. The 
proposed areas for treatment are alfalfa fields that are contained 
within larger application blocks of rangeland on, or adjacent to, the 
Flathead Reservation. The Flathead Reservation is located in Sanders, 
Lake, Flathead and Missoula Counties in Montana. Applications will 
occur primarily on the Flathead Nation near Irvine Flats in Sanders 
county Montana. The area is primarily rangeland with some production of 
alfalfa grown under irrigation. Aerial applications will be made using 
fixed wing aircraft making broadcast applications or by using Reduced 
Area Agent Treatments (RAAT). This method uses alternating swath 
applications to the spray block providing effective control while 
reducing environmental loading. The rate of application is 0.016 lb 
active ingredient (ai) per acre at the full rate and 0.012 lb active 
ingredient per acre using the RAAT. One application of a 22% ai product 
will be made between May and September 2008. A maximum of a 48 lb. ai 
will be applied.
    This notice does not constitute a decision by EPA on the 
application itself. The regulations governing section 18 of FIFRA 
require publication of a notice of receipt of an application for a 
specific exemption proposing a use which is supported by the IR-4 
program and has been requested in 5 or more previous years, and a 
petition for tolerance has not yet been submitted to the Agency.
    The Agency, will review and consider all comments received during 
the comment period in determining whether to issue the specific 
exemption requested by the USDA/APHIS.
