LEWISTON, Minn. — Although a Danish company has withdrawn plans for a biogas plant in Winona County, other companies soon may be eyeing the area to tap massive quantities of farm manure to convert to natural gas. Such is the concern of the environmentally driven Land Stewardship Project. The organization has scheduled a program for Monday about perils of manure-digester plants. Time: 6 p.m. at the Lewiston Community Center. The speakers:
> Tim Ahrens, of Altura, a critic of digesters.
> Bethany Erck, a South Dakota farmer with a large-scale digester next door.
> Kim Dupre, an environmentalist expert on digesters.
> Vance Haugen, a Fillmore County farmer who has researched djgesters.
