Spatial Aquatic Model Development; Notice of Public Meeting

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

[[Page 60849]]

SUMMARY: A simultaneous workshop and webinar on a regional test version 
of the Spatial Aquatic Model (SAM) will be held on October 29, 2014. 
This Notice announces the location and time for the meeting and 
provides a tentative list of topics to be covered in the meeting. With 
the development of SAM, EPA will be able to determine the magnitude, 
length, and duration of exposure to a chemical as well as where the 
exposure may occur.

DATES: The meeting will be held on October 29, 2014 from 8:30 a.m. to 1 
p.m. Requests to participate in the meeting must be received on or 
before October 20, 2014.
    To request accommodation of a disability, please contact the person 
listed under FOR FURTHER INFORMATON CONTACT, preferably at least 10 
days prior to the meeting, to give EPA as much time as possible to 
process your request.

ADDRESSES: The meeting will be held at the Environmental Protection 
Agency, Office of Pesticide Programs (OPP), One Potomac Yard (South 
Building), Fourth Floor Conference Room N4830, 2777 S. Crystal Drive, 
Arlington, VA 22202.

Environmental Fate and Effects Division, Office of Pesticide Programs, 
Environmental Protection Agency, 1200 Pennsylvania Ave. NW.,

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-2014-0686, 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), West William Jefferson Clinton Bldg., Rm. 3334, 
1301 Constitution Ave. NW., Washington, DC 20460-0001. The Public

additional information about the docket available at http://www.epa.gov/dockets.

II. Background

    EPA is developing a Spatial Aquatic Model (SAM) to address the need 
for more spatial and temporal contexts for pesticide aquatic exposure 
assessments. The model will provide a way to estimate how often, how 
long, and where adverse impacts overlap spatially with populations at 
risk. EPA plans to introduce an alpha test version of SAM at the 
workshop/Webinar to allow interested parties to evaluate and comment on 
the model.

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-
2014-0686, must be received on or before 10 days after date of 
publication in the Federal Register.

IV. Tentative Topics for the Meeting

    The workshop/Webinar will provide an overview of the Spatial 
Aquatic Model, a description of the model and data components, 
contrasts with current OPP aquatic exposure models, and preliminary 
evaluations of model performance. The workshop will include a hands-on 
demonstration of the test model so that participants will be able to 
evaluate/test the model and provide feedback that can be used to update 
and improve the model. Participants will have an opportunity to provide 
comments to the Agency and participate in a follow-up Webinar in 
January 2015.
