What is the Residual Risk Program?
Under the Clean Air Act, EPA is required to develop and implement a program for assessing risks remaining (i.e., the residual risk) after facilities have implemented maximum achievable control technology (MACT) standards. If necessary, EPA is required to issue regulations to reduce any residual risks in order to protect the public health with an “ample margin of safety”. Also, if needed, EPA is required to prevent “adverse environmental effects”, taking into consideration costs, energy, safety and other relevant factors. If needed, EPA must issue risk-based regulations, within eight (or nine) years after EPA issues an air toxics standard for a given source category. On March 3, 1999, EPA issued the Residual Risk Report to Congress. The report describes the methodologies and data required for assessing if any residual risk remains from air toxics emissions from source categories for which MACT standards have been issued. This report also presents the general framework EPA will use in co
