A proposed biofuel plant in Le Sueur could be headed for a public vote. Petitions with hundreds of signatures have been turned over to the Le Sueur City Council, the first step in a process to set up a referendum on the 30-million dollar plant. The idea for a facility that would convert food-processing and animal waste into energy in Le Sueur was initially proposed in 2009. Opponents of the plant say it would reduce property values for those living near it and would affect air quality. Supporters say the project would generate well-paying jobs in addition to supplying the community with 40-percent of its power needs. The plant would convert corn silage, chicken manure and potato-processing residue into energy.
