12. Visibility Requirements Section 169A of CAAA of 1977 requires “as a national goal the prevention of any future, and the remedying of any existing, impairment of visibility in Class I areas which impairment results from manmade air pollution.” Visibility regulations (July 1, 1999) require “reasonable progress” to achieving natural conditions by the year 2064
