This data set contains the boundary that comprises the area in East Helena, Montana that was designated nonattainment for the National Ambient Air Quality Standard (NAAQS) for lead. This area is identified in 40 CFR 81.327.
Clean Air Act Amendments give EPA the authority to develop the NAAQS for airborne pollutants that have harmful effects on public health. These amendments require states to develop air pollution control plans to protect these national standards and maintain good air quality.
Nonattainment areas are areas subject to additional air quality planning provisions.
