Iron and Steel Foundry Residual Risk and Technology Review Major Source Rule
The Risk and Technology Review (RTR) is a combined effort to evaluate both risk and technology as required by the Clean Air Act (CAA) after the application of maximum achievable control technology (MACT) standards. Specifically, Section 112(f)(2) directs EPA to conduct risk assessments on each source category subject to MACT standards, and to determine if additional standards are needed to reduce residual risks. Section 112(d)(6) of the CAA requires EPA to review and revise the MACT standards, as necessary, taking into account developments in practices, processes and control technologies.
EPA has scheduled promulgation of the Iron and Steel Foundry Residual Risk and Technology NESHAP for the 2019/2020 timeframe. Additional information is provided in the following weeks.
