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.
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.
