The Massachusetts Department of Environmental Protection (MassDEP) in January 2008 submitted to the U.S. Environmental Protection Agency (EPA) State Implementation Plan (SIP) for attaining the federal 8-hour National Ambient Air Quality Standard (NAAQS) for ground-level ozone. The SIP describes the national, regional and local control measures to be implemented to reduce emissions, and uses air quality modeling and other analyses of air quality and meteorological data to demonstrate that Massachusetts is likely to attain the NAAQS for ozone by 2009.
