SUPPLEMENTARY INFORMATION:
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
11).
Utilities (NAICS code 22).
Professional, scientific and technical (NAICS code 54).
B. How can I get copies of this document and other related
information?
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
Ave. NW., Washington, DC 20460-0001. The Public Reading Room is open

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.
IV. Tentative Topics for the Meeting
1. Development and evaluation of the Pesticide Root Zone Model
(PRZM) for estimating pesticide concentrations in groundwater.
2. Status of Drinking Water intake Watershed PCA development
exercise.
3. RQ calculations for specific listed terrestrial mammals, birds,
reptiles, and amphibians: Model Parameterization and Knowledge base
