The purpose of this background information document (BID) is to summarize the background information gathered and the analyses performed during the development of the proposed friction materials manufacturing national emission standard for hazardous air pollutants (NESHAP). This chapter presents the statutory basis for the NESHAP, and a discussion of the source category listing. Chapter 2 characterizes the friction materials manufacturing industry, including an industry profile, process description, characterization of organic hazardous air pollutant (HAP) emissions, and a summary of existing State regulations applicable to friction materials manufacturing facilities. Chapter 3 describes organic HAP emission control techniques that are currently being used at friction materials manufacturing facilities and discusses pollution prevention options for reducing air emissions of HAP. Chapter 4 describes the rationale for the determination of maximum achievable control technology (MACT) floors, regulatory options for specific segments of the friction materials manufacturing industry, and compliance assurance monitoring options. Chapter 5 describes the model process units developed to evaluate the effects of the various control options. Chapter 6 presents estimates of primary air impacts, secondary environmental impacts, and energy impacts for existing sources resulting from the control of HAP emissions under the proposed standards. Chapter 7 presents the cost of applying the control options and monitoring required to meet the MACT standards and to ensure continuous compliance.
