The Clean Air Act Amendments (CAAA) of 1990 required areas designated as being in violation of the National Ambient Air Quality Standards for particle matter measuring less than or equal to 10 micrometers in aerodynamic mass median diameter (PM-10) to submit State Implementation Plans (SIPs) beginning with Base Year inventories. In recent years, PM-10 has been a subject of debate over the relative health danger posed by particulate matter. According to the U.S. Environmental Protection Agency (EPA), as of January 1996 there were approximately 82 PM-10 nonattainment areas nationwide which encompass a population of approximately 68 million people. In an effort to support the successful implementation of the CAAA and to provide support and information to the transportation community and state planning agencies, the Federal Highway Administration (FHWA) is seeking to provide an overview of PM-10 requirements and SIP contents. this document reviews U.S. EPA's PM-10 guidance documentation and the contents of 1990 Base Year PM-10 SIPS from various regions throughout the country including: Denver, CO; Boise, ID; Spokane, WA; Phoenix, AZ; and Presque Isle, ME. The report discusses the contents of PM-10 emissions estimation methodologies, PM-10 modeling techniques, and PM-10 control measures.
