II. Background

On a biannual interval, an Environmental Modeling Public Meeting 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/​.

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 Confidential Business Information (CBI). Requests to participate in the meeting, identified by docket ID number EPA-HQ-OPP-2009-0879, must be received on or before June 5, 2017.

IV. Tentative Theme for the Meeting

Subsurface Metabolism: Groundwater modeling conducted as part of the pesticide registration and re-evaluation processes typically assumes that biologically mediated metabolism does not occur at depths greater than 1 meter. The focus of this EMPM meeting concerns evidence of subsurface metabolism in groundwater, methods for measuring subsurface metabolism, and how to parameterize models to account for subsurface metabolism. As always, other timely topics beyond subsurface metabolism will be considered as time limits allow.

Authority Code: 7 U.S.C. 136 et seq.

Director, Environmental Fate and Effects Division, Office of Pesticide Programs.
