National Emission Standards for Hazardous Air Pollutants: Iron and Steel Foundries Major Source Residual Risk and Technology Review and Area Source Technology Review

Özet

This action finalizes the residual risk and technology review (RTR) conducted for the major source Iron and Steel Foundries source category and the technology review for the area source Iron and Steel Foundries source category regulated under national emission standards for hazardous air pollutants (NESHAP). In addition, we are taking final action to remove exemptions for periods of startup, shutdown, and malfunction (SSM) and to specify that emissions standards apply at all times. These final amendments also require electronic reporting of performance test results and compliance reports and make minor corrections and clarifications to a few other rule provisions for major sources and area sources.
