Nebraska lawmakers on Friday passed a bill that would increase fines for truckers who spill livestock manure in Omaha.

The bill sets the minimum fine of $250 for violations.  Senator Heath Mello of Omaha introduced the bill to increase the fine from its current $100. Mello says the current fine was so low that it encouraged some bad actors to dump the contents of their trucks instead of washing them.

Omaha saw 42 documented manure spills between August 2009 and October 2010, most of which were near the meatpacking plants in Mello's south Omaha district.
