(Richmond, IN)--There has been no information from any public agency indicating any environmental effects from the semi crash that closed I-70 Tuesday morning.  INDOT did confirm Tuesday that diesel fuel was spilled in a low-lying area with water between Chester Boulevard and Union Pike when the semi went off the road and down an embankment late Monday night.  Westbound I-70 finally reopened at around 10 o’clock Tuesday morning, ending what turned out to be a closure of more than ten hours.  There was still no word Wednesday morning on the identity or condition of the driver or what caused the crash.
