This PR Notice does not present new rules, policies, or interpretations, but rather summarizes, explains, and provides guidance regarding compliance with existing rules under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Federal Food, Drug, and Cosmetic Act (FFDCA). This PR Notice elaborates on policies described in the August 2, 2002, Federal Register Notice, Proposed Federal Actions to Update Field Test Requirements for Biotechnology Derived Plants and to Establish Early Food Safety Assessments for New Proteins Produced by Such Plants. ( http://www.ostp.gov/html/redregbio.html). The use of bioengineered plants for food production, including plants engineered to express plant-incorporated protectants, has markedly increased over the past decade. Some researchers and other users of PIPs may not be aware of their obligations regarding small-scale field studies, and because those obligations are contained in several regulations, the Agency seeks to facilitate understanding of the requirements and prevent potential violations. More information on plant-incorporated protectants is available on EPA's Web site at http://www.epa.gov/pesticides/biopesticides/pips/index.htm.
