  1. Planning for the Past Michigan State University

  2. Farm Lane Underpass Project • Began in October 2007 • Project designed to eliminate traffic congestion and required tunneling under two rail crossing on campus • Farm Lane is major road through campus

  3. PROJECT SCOPE IN TWO PHASES

  4. FINDING SKELETONS FROM THE PAST

  5. November 2007: Michigan Department of Transportation (MDOT) discovers waste material during Phase 1 excavation. The material was identified by MSU as Coal Ash.

  6. Coal Ash discovery changes the Phase 1 approach

  7. Coal ash levels of arsenic, boron, cadmium, lithium, and mercury exceeded the Michigan Department of Environmental Quality (MDEQ) 201 clean-up criteria and were therefore reported.

  8. Coal Ash depth reaches over 18’

  9. Geoprobe borings conducted to identify extent of Coal Ash

  10. COAL ASH DEFINED DURING PHASE I

  11. Ten monitoring wells installed at various depths throughout the area

  12. NOT ALL COAL ASH IS CREATED EQUAL

  13. PHASE I OF PROJECT & COAL ASH DISPOSAL • 92,000 cubic yards removed and taken to a Class II Landfill • Cost exceeded 1.2 Million Dollars • Removal time exceeded four weeks • Some delays in project

  14. PHASE II RAIL UNDER-PASS

  15. MORE COAL ASH DISCOVERED

  16. TUNNELING UNDER NEW RAIL BRIDGES

  17. STAGING OF COAL ASH

  18. MSU EVALUATED HOW CLEAN IS CLEAN,COST AND RISK • MSU evaluated risk of leaving some coal ash on site vs. removal to clean closure • Coal ash does not leach, limited land use restriction since MSU property • Cost of transport and disposal • Jolly Road site already had similar ash material • Located in secure area • PR exposure

  19. MSU MEETS WITH MICHGIAN MDEQ

  20. MDEQ DISCUSSIONS • MSU discuss option for T.B. Simon Power Plant and surrounding property listed as MDEQ 201 Site. • MSU Staff list reasons, risk and long term site strategies • MDEQ accepts, MSU has new 201 site • MSU had stayed transparent with MDEQ during discovery of coal ash on site

  21. EXTENT OF KNOWN COAL ASH

  22. The EHS Department is often the fall guy for explaining environmental rules to others…

  23. PREPARATION OF JOLLY ROAD SITE FOR COAL ASH

  24. Coal Ash Berm- Jolly Rd.

  25. Coal Ash South End, Total volume moved to date 29,000 yards

  26. Phase II: Progress as of July 2009

  27. LONG TERM REQUIREMENTS • Monitoring wells located at Jolly Road Site • Maintain cap on berm • Maintain surface areas at power plant to prevent any coal ash exposure • Submittal of annual report to MDEQ • Adequate Insurance

  28. Coal Ash Management During Coal ModificationProject

  29. COAL ASH: THE NEVER-ENDING STORY
