Synthetic biology startups create engineered organisms with no required environmental release monitoring

Startups engineering microbes for agriculture (nitrogen fixation), materials (spider silk), and bioremediation release engineered organisms into the environment with minimal regulatory oversight. The EPA's TSCA process for engineered microbes takes 90 days and requires only a pre-manufacture notice, not an environmental impact assessment. Once released, engineered organisms can horizontally transfer genes to wild populations through mechanisms that are poorly understood. This persists because TSCA was designed for chemical substances, not self-replicating organisms, and updating the regulatory framework for synthetic biology has stalled in Congress for a decade.
