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 
from 8:30 a.m. to 4:30 p.m., Monday through Friday, excluding legal 
holidays. The telephone number for the Public Reading Room is (202) 
566-1744, and the telephone number for the OPP Docket is (703) 305-
5805. Please review the visitor instructions and additional information 
about the docket available at http://www.epa.gov/dockets.

II. Background

    On a biannual interval, an Exposure Modeling Public Meeting (EMPM) 
is held for presentation and discussion of current issues related to 
modeling pesticide fate, transport, and exposure for 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/. The EMPM scheduled for October 2013 
was canceled due to the government shutdown. As a consequence, EPA will 
use the October 2013 agenda at the March 24, 2014 meeting with the 
addition of a presentation on PRZM-GW model implementation and 
evaluation due to extensive stakeholder interest.

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 March 7, 2014.

IV. Tentative Topics for the Meeting

    1. Estimating the magnitude of pesticide effects on avian 
reproductive success: Markov chain nest productivity model (MCnest).
    2. The Surface Water Concentration Calculator.
    3. Development of a conceptual model for estimating aquatic 
exposure from the use of pesticides on rice using the Pesticide Flooded 
Application Model.
    4. Evaluation of NAFTA kinetics guidance.
    5. Comparison of multiple spray drift deposition data sets.
    6. Guidance on modeling offsite deposition of pesticides via spray 
drift.
    7. Use of the OECD ENASGIPS tool in U.S. settings.
    8. A better sorption model for predicting pesticide behavior.
    9. The significance of time-dependent sorption on leaching 
potential: A comparison of measured field results and modeled 
estimates.
    10. Evaluation of PRZM-GW using long-term ground water monitoring 
data.
