  7. 8.Mar-08 Received BM initial cost estimate for a DB Boiler 6 plant addition • $76Mfor 250 Klb/hr of capacity Houston we have a problem!

  8. Apr-08 Received BOT approval to hire Design Criteria Developer for DB Process • Lutz Daily & Brain selected • Oct-08 Received LDB revised scope cost estimates • 200 Klb/hr as plant addition - $56M • 200 Klb/hr replace boiler 1 - $49M • Feb-09 Received BOT approval for engineering design services to replace Boiler 1 with Boiler 6 • Lutz Daily & Brain selected Houston we have another problem! What about lost boiler 1 capacity during construction? Change of Plans(new ride direction)
