BELLE, Mo. -

Osage County deputies busted what Sheriff Michael Dixon called one of the largest operating anhydrous ammonia meth lab he had ever seen.

It happened around 10:30 p.m. Friday night on County Road 739 in Belle.

Baumgartner was been charged and was being held without bond Saturday night.

He was charged with meth manufacturing and two counts of felony possession of a controlled substance.

Deputies and the Lake Area Narcotics Enforcement Group found late Friday a bunker with ten tanks of anhydrous ammonia.

Sheriff Michael Dixon said it is unusual for an operations this size because of laws against pseudoephedrine.
