the near term will involve completion of high priority feasibility 

 studies on the "original" portion of the Silver Bow Creek site, 

 screening evaluations followed by Remedial Investigation/Feas- 

 ibility Study planning and implementation for new study areas 

 of the site (Butte Addition, Clark Fork River, Warm Springs Ponds 

 to Milltown) requiring detailed investigation. Screening act- 

 ivities will define immediate public health or environmental 

 priorities which can be addressed via a fast track removal action. 

 Additionally, an "operable unit" management approach is being 

 utilized on the site which is intended to allow corrective action 

 to proceed at site subunits without requiring all site invest- 

 igations to be completed.
