I. General Information

A. Does this action apply to me?

    You may be potentially affected by this action if you are required 
to conduct testing of chemical substances under the Toxic Substances 
Control Act (TSCA), the Federal Food, Drug, and Cosmetic Act (FFDCA), 
or the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). 
Since other entities may also be interested, the Agency has not 
attempted to describe all the specific entities that may be affected by 
this action. The following list of North American Industrial 
Classification System (NAICS) codes is not intended to be exhaustive, 
but rather provides a guide to help readers determine whether this 
document applies to them. Potentially affected entities may include:
     Agriculture, forestry, fishing and hunting (NAICS code 
     Utilities (NAICS code 22).
     Professional, scientific and technical (NAICS code 54).

 B. How can I get copies of this document and other related 

    The docket for this action, identified by docket identification 
(ID) number EPA-HQ-OPP-2009-0879, is available at http://www.regulations.gov or at the Office of Pesticide Programs Regulatory 
Public Docket (OPP Docket) in the Environmental Protection Agency 
Docket Center (EPA/DC), EPA West Bldg., Rm. 3334, 1301 Constitution

II. Background

    On a biannual interval, an Exposure Modeling Public Meeting will be 
held for presentation and discussion of current issues related to 
modeling pesticide fate, transport, and exposure of risk assessment in 
a regulatory context. Meeting dates and abstract requests are announced 
through the ``empmlist'' forum on the LYRIS list server at https://lists.epa.gov/read/all_forums.

III. How can I request to participate in this meeting?

    You may submit a request to participate in this meeting to the 
person listed under FOR FURTHER INFORMATION CONTACT. Do not submit any 
information in your request that is considered CBI. Requests to 
participate in the meeting, identified by docket ID number EPA-HQ-OPP-
2009-0879, must be received on or before October 22, 2012.
