For the Rv (revisions) column,
* indicates that the record contains one or more chemicals at facilities whose TRI air releases or incineration transfers for 2010 were revised downwards since 2010, and whose hazard and score have been adjusted accordingly.
** indicates one or more chemicals at facilities whose quantities were revised upwards, or both upwards and downwards. Chemicals revised upwards had their pounds adjusted, but not their score.
*** indicates that the RSEI microdata do not match the public RSEI data.
