Number of Records: 3,177
Note: The totals include only those entries matched to a parent company. The industry designation is the primary one for the parent's operations overall. The totals are adjusted to account for the fact that each parent's entries may include both agency records and settlement announcements for the same case; or else a penalty covering multiple locations may be listed in the individual records for each of the facilities. They are also adjusted to reflect cases in which federal and state or local agencies cooperated and issued separate announcements of the outcome. Duplicate or overlapping penalty amounts are marked with an asterisk in the individual records list below.
