 pre-application meetings. Our knowledge of potential adverse effects 

 on National Forests significantly contributes to the review process. 

 New- Source Review works best in States or portions of States that have 

 low air pollution loadings. 



Forest Service research is making progress in the identification, 

 quantification, and mitigation of air pollution effects on 

 ecosystems. Forest Service research contributed scientific data 

 during the acid rain debate that culminated in the 1990 Clear Air Act 

 Amendments. Studies on air pollution effects continue. Additionally, 

 the Forest Service participates with EPA and State agencies in the new 

 Forest Health Monitoring initiative. 



Opportunites exist for improvement of implementation of the Clean Air 

 Act such as the incorporation of new technology in our modeling and 

 there is a need, as demonstrated by the Mt . Zirkel situation, to 

 establish regulations to protect sensitive aquatic and terrestrial 

 resources from new and existing air pollution impacts. 



All of the involved agencies appear ready to do what is necessary to 

 continue implementation and provide clean air for the country, 

 particularly in Class I areas. The availability of resources will be 

 the determining factor for the speed of conducting scientific research 

 and monitoring activities. 



This completes my testimony. I will be pleased to answer any 

 questions you may have.
