This report features two topics: (1) the current evaluation of all State Implementation Plans (SIPs) to determine by July 1, 1976, those that are 'substantially inadequate' and need revisions to attain and maintain the National Ambient Air Quality Standards (NAAQS); and (2) an overview of EPA's carbon monoxide/oxidant control strategies, with an emphasis on control of transportation-related sources of these pollutants. Also included in this report are summaries of SIP-related actions published in the Federal Register during this reporting period, ambient air quality and trend data for 1974, and stationary source compliance information. Since the last report in this series (EPA-450/2-75-008, September 1975), the number of major sources identified has increased by 2,463 to 21,823; 84 percent of these are now in compliance with an emission standard or on an acceptable compliance schedule.
