        The estimated  amount of polymer  removed  from  the  pipeline was  5m .
     This estimate includes polymer removed from cut-outs, separators,  and filter
     bags.  All of these  held polymer  in  different  forms,  some  loose,  some com-
     pacted, making an accurate volume estimate difficult. The amount of polymer
     removed supports the estimates generated from roughness calculations prior
     to  the  cleaning.  AGEC  will  continue  to  monitor  polymer  build-up  using
