This revision pertains to the Commonwealth's attainment plan for the North Reading nonattainment area (``North Reading Area'' or ``Area'') for the 2008 lead national ambient air quality standards (NAAQS), and includes a base year emissions inventory, an analysis of reasonably available control measures (RACM) (including reasonably available control technology (RACT)), a plan for reasonable further progress (RFP), a modeling demonstration of lead NAAQS attainment, and contingency measures. This action is being taken under the Clean Air Act (CAA).
