WHAT DO THESE DATES HAVE IN COMMON (Sept.28/10, March 31/11, June 9/11)

These dates are the three most recent dates of illegal emissions, fires or explosions at Chemtura Canada in Elmira. I was asked weeks ago to produce a list of all the fires, explosions and emissions over the last twenty years at Chemtura in Elmira. I apologize for my tardiness and will try to get at it this weekend. The last event (yesterday) apparently was relatively minor if such a thing is possible at a chemical plant. Today's Woolwich Observer has the story "Fire brings crews to Chemtura plant".
