2. Hazmat Events Leading up to the NPRM A Series of accidents involving TIH Industry attempts to reach consensus on improvements AAR-driven actions and the circulars Tank Car/Chemical industry call for government action Public Meetings 2 in 2006, 1 in 2007 Dow/UP/UTLX NGRTC Project involvement

3. Hazmat The Proposal Issued April 1, 2008 Docketed in 2 locations: HM-246 FRA-2006-25169 Comments closed June 2, 2008 Two-fold approach to the problem Engineering controls Operational Controls

5. Hazmat What we propose (Car enhancements) Proposed performance standard to resist head/shell puncture or other catastrophic loss under forces at 50 mph (closing speed is ~ ½ of train speed) Apply to all cars carrying TIH materials

6. Hazmat Car Requirements 25 MPH Shell Test 30 MPH Head Test Validated: Full-scale testing Component testing Modeling/Analysis

7. Hazmat What we propose (Operations) 50 MPH Speed Restriction Interim measure— 30 mph speed restriction in dark territory based on ­Higher train mile collision risk ­Derailment risk absent broken rail detection Make exceptions for territories with PTC, SPMS, track integrity circuits, other measures?

8. Hazmat Proposed Timeline 2 years for engineering development 6 years for fleet replacement 50% completion by end of year 3 Pre-89 removal by end of year 5 Reporting to FRA on progress (5 years + 2 months)

9. Hazmat What we are NOT proposing Top-Fitting Protection

10. Hazmat Next Steps Review comments Written and Oral Consider interim measures to address transitional needs for tank cars. Awaiting joint industry submission Begin development of final rule Continue testing program and NGRTC cooperation
