The Toxic Substances Control Act (TSCA) is the legislation used by the U.S. Environmental Protection Agency to regulate releases of genetically engineered microorganisms. The rule defining the scope of the notification requirements for releases of microbial products of biotechnology was published in April 1997. The Environmental Protection Agency (EPA) had some latitude regarding the extent to which various categories of microorganisms would be regulated, but the agency was constrained by requirements of TSCA and an interagency agreement about how to regulate products of biotechnology. This paper investigates the extent to which the scope of oversight is based on risk. A risk-based rule is defined as one where the reporting requirements are based on potential for exposure or expected adverse effects. The evolution of the rule is described, and risk-based components are discussed. In conclusion, the scope of oversight of microbial releases is determined to be based on risk to the extent that legislation and institutional constraints permit.

In September 2015, VW had admitted to United States regulators that it had deliberately installed “defeat devices” in many of its diesel cars, which enabled the cars to cheat on federal and state emissions tests, making them able to pass the tests and hit ambitious mileage and performance targets while actually emitting up to 40 times more hazardous gases into the atmosphere than legally allowed. The discovery had prompted the U.S. Environmental Protection Agency (EPA) to halt final certification of VW’s 2016 diesel models, and VW itself had halted sales of its 2015 models. As fallout from the defeat devices developed, VW posted its first quarterly loss in more than 15 years, and its stock plummeted. Top executives were replaced, and VW abandoned its goal of becoming the world’s largest automaker. Stakeholders around the world had been asking since the scandal broke: “How could this have happened at Volkswagen?”
