Findings and actions by the IR-4 Project in response to a bushel of EPA inspections.

The IR-4 Project is dedicated to all aspects of minor crop pest management, in cooperation between USDA, universities, and other state or Federal entities. Human safety decisions made by EPA are based upon field raw data, analytical reports, and scientific review and interpretation. Quality Assurance personnel, an independent body of internal inspectors and auditors, assist both regulatory inspector and on-site field personnel during EPA site inspections. This article contains information gleaned from a large number of university and other test site inspections, which were conducted by EPA to fulfill requirements of Good Laboratory Practice regulations, 40 CFR 160.
