This action finalizes the residual risk and technology review (RTR) conducted for the Rubber Tire Manufacturing source category regulated under national emission standards for hazardous air pollutants (NESHAP). In addition, we are taking final action to add electronic reporting of performance test results and reports, compliance reports, and Notification of Compliance Status (NOCS) reports and to remove the provision that exempts emissions from compliance with the standards during periods of startup, shutdown, and malfunction (SSM). These amendments are made under the authority of the Clean Air Act (CAA) and will improve effectiveness of the rule. The amendments are environmentally neutral.
