regulatory action to improve and protect visibility," some 

 members of the commission's working committees continue to argue 

 that scientific information is insufficient to recommend 

 regulatory actions. Such intentional efforts to delay or avoid 

 decisions are likely to succeed if agencies are unable to provide 

 the leadership and technical expertise to complete the work. 



Finally, there are many good reasons why the EPA should be 

 encouraged to move forward in promulgating much-delayed 

 regulations to control regional haze in the Grand Canyon region. 

 Nonetheless, the Grand Canyon Trust recommends that such 

 regulations be deferred until the GCVTC makes its 

 recommendations, assuming that the commission is sufficiently 

 funded to complete its process. The potential to achieve a 

 broadly-supported and effective long-term strategy to protect the 

 region from visibility impairment offers sufficient reason to 

 give the process mandated by the 1990 CAAA a chance to succeed. 

 If it does not, EPA can still apply its broad discretionary 

 authority to ensure the long-term protection of the crystal clear 

 vistas of the Colorado Plateau. 



Thank you. I would be happy to respond to any of your questions.
