Current copies of the air pollution control regulations of all fifty states, three territories, and twelve local agencies were reviewed for the purpose of compiling information on emission standards, compliance test methods, and continuous emission monitoring, as applied to existing stationary sources. Specific pollutants of interest were opacity, SO2, NOx, and sulfur compounds other than SO2. The intent of this review was to identify the assortment of types, formats, and exemptions which prevail in existing SIP regulations for selected sources and pollutants, thereby providing guidance to EPA for writing future continuous emission monitoring regulations. This report is not to be used as an all inclusive reference document for such information. The report is organized into a separate Executive Summary and three volumes. The first volume contains an analysis of state adopted emission standards for opacity, SO2, NOx, malfunctions and scheduled maintenance, and continuous monitoring regulations for existing stationary sources. Volume II provides a tabular summary of key components of the applicable emission standards and regulations including source category, minimum source capacity, averaging time of standard, exemptions, etc. Volume III of the report contains the complete text of the regulations cited.
