LINDEN — Some residents are organizing against plans for a nearly 9,000-head hog operation in Montgomery County. The proposal submitted to the Indiana Department of Environmental Management calls for two barns each holding 4,400 finishing swine on land about a mile from Linden. Bowlder Ridge LLC, an apparent subsidiary of Linden-based Hudson Farms, has begun seeking approval to build the confined animal feeding operation near the farm’s offices. Nearby residents say they’re concerned about noise, odors and increased truck traffic on gravel roads from the proposed confined animal feeding operation and are organizing a petition drive opposing the project in the area about 25 miles south of Lafayette. IDEM is seeking public comment on the application. If the permit is granted, the project has to be approved by county commissioners before construction can begin.
