The outer limit of the cone depression from coal seam dewatering 

 remained about the same distance north of the International 

 Boundary and total pumpage increased 10 percent. 



The total estimate of seepage from the ash lagoons and polishing 

 ponds was 0.75 litre per second, well below the seepage limits 

 proposed by the International Poplar River Water Quality Board. 

 The leachate front was calculated to have advanced 8.31 metres 

 towards Cookson Reservoir since the ponds were first filled. 



Plant stack emissions did not cause or contribute to violation of 

 Montana, United States or Saskatchewan ambient air quality 

 standards .
