The national visibility goal was established in section 169A of the 1977 Clean Air Act (CAA) as 'the prevention of any future, and the remedying of any existing, impairment of visibility in mandatory Federal Class 1 areas which impairment results from manmade air pollution.' There are 156 mandatory Federal Class 1 areas identified for visibility protection under this provision. Section 169B of the 1990 CAA Amendments required EPA to issue a report to Congress estimating the visibility improvement expected in these 156 areas resulting from implementation of the 1990 Amendments. In October 1993, EPA issued its report entitled Effects of the 1990 Clean Air Act Amendments on Visibility in Class 1 Areas: An EPA Report to Congress (EPA 452/R-93-014). Section 169B also requires EPA to provide Congress with regular assessments of the actual progress and improvements in visibility in the mandatory Federal Class 1 areas. This document is the first report to Congress that reviews past progress. This report presents visibility trends and analyses of annual and seasonal pollutant composition based on 1994-1998 monitoring data from 46 sites.
