In the mid-1980`s, decreasing visibility in the Dallas-Fort Worth area led to interest in the causes of that trend and in ways to mitigate it. Both white and brown winter hazes were identified. It was assumed that much of the white haze derived from sulfur dioxide emissions from coal-burning power plants and other industrial facilities outside the Dallas-Fort Worth Metroplex. Concerns about the haze led Texas to issue a rule in 1992 requiring some older power plants of TU Electric to reduce their emissions if that would lead to significant improvements. This three volume report describes the potential improvements in wintertime visibility in the Dallas-Fort Worth area, if the sulfur dioxide emissions from two lignite-burning power plants were to be limited. It also identifies other factors causing the hazes. Volume 1 summarizes the entire 3 year project (1993-1996); Volume 2 describes measurements and haze climatology; while Volume 3 describes how novel information and assessment methods address the problem.
