population increases would be offset by application of control measures. This, 

 taken with a projected small growth in electrical energy demand, means there 

 would be little change in Western regional visibility conditions. Consequently, 

 there will still be perceptible man-made regional visibility impairment in all class I 

 areas nationwide. 



As I indicated earlier, the Act contains provisions to address regional 

 visibility. The timing of EPA's responsibility to address regional haze regulatory 

 requirements is keyed to the final report of the Grand Canyon Visibility Transport 

 Commission. Required under section 169B of the amended Act, the Commission is 

 comprised of eight Western states -- Colorado, New Mexico, Utah, Nevada, 

 Oregon, Arizona, Wyoming and California -- as well as EPA, the National Park 

 Service, the U.S. Forest Service, the U.S. Fish and Wildlife Service, and the Bureau 

 of Land Management. EPA is currently working with the Commission to improve 

 representation of Native-Americans of the region on the Commission and its 

 committees. 



EPA established the Commission on November 13, 1991 and broadened its 

 scope to look at regional haze impairment for all class I areas on the Colorado 

 Plateau which is located near the Four Corners area of New Mexico, Colorado, 

 Utah and Arizona. The Commission is charged by statute with developing a report 

 to EPA by November 1 995. The Act calls for the report to include 

 recommendations to EPA on what measures should be taken under the Clean Air 

 Act to remedy adverse visibility impacts. Among other things, the Commission is 

 specifically charged with examining whether areas of the western eight-State 

 region can be defined as "clean air corridors" and whether alternative siting 

 assessments should be required for certain new sources locating in such "clean air 

 corridors." In addition, the Act specifically calls for the Commission's 

 recommendations to address long-range strategies for addressing regional haze in 

 affected class I areas. The Commission's work is managed by the Western 

 Governors' Association. The Commission has established several technical policy
