FOREWORD 



The Old West Regional Commission wishes to express its appreciation for 

 this report to the Montana Department of Natural Resources and Conservation, 

 and more specifically to those Department staff members who participated 

 directly in the project and in preparation of various reports, to Dr. Kenneth A. 

 Blackburn of the Commission staff who coordinated the project, and to the 

 subcontractors who also participated. The Yellowstone Impact Study was one 

 of the first major projects funded by the Commission that was directed at 

 investigating the potential environmental impacts relating to energy develop- 

 ment. The Commission is pleased to have been a part of this important research.
