The booked cost was $9 MM. General breakdown is as follows: Electrical Power Fuel gas Abandonment costs (Tank and line cleaning SD of Units) Miscellaneous $ 1 MM 2 MM 5 Mi 1 MM $ 9 MM Enid had 8 operating units with contiguous offsite tankage and pipelines. Corpus has 17 operating units In the East Plant, has separate offsite areas, l.e., 90-91 area. Docks 1, 2, 3 and 6, PPG dock, S.W. dock, Deep Sea Terminal, and West Plant. Due to number of units and complexity of offsites a factor of 3 times Enid costs is considered in the ball park for factoring to Corpus. CH 009324
