The Western Region IR-4 is managed by the Field Office, the Quality Assurance Unit and the Analytical Lab. In addition, there is a State Liaison Representative of university extension personnel for each state in the region.
The Field Office serves as the focal point of communication between stakeholders in the region and the national program and coordinates research trials for food and ornamental crops. Personnel work with all three program areas: Food Use, Environmental Horticulture and Integrated Solutions.
The Quality Assurance unit ensures that field residue trials in the Food Use program and subsequent sample analysis are in compliance with the EPA’s Good Laboratory Practices, the study protocol and facility documents. This is accomplished by inspecting field, processing, and laboratory critical events and reviewing the generated data before it is submitted to the agency.
The Analytical Lab is responsible for the receipt, processing, analysis and long term storage of the food crop samples received from the field residue trials. Upon completion of the analytical phase, the laboratory prepares a final report for included with the submission documents sent to EPA for registration evaluation.
