Huge poultry and pig operations in Missouri would face new regulations under a bill receiving preliminary approval in the House, though debate concentrated on whether such operations undermine the state’s traditional way of farming. Those huge, confined hog and poultry farms would come under the regulation of the Clean Water Commission, rather than the Department of Natural Resources. More poultry farms would come under state regulation, while smaller hog farms would be exempt from current notification requirements. Some lawmakers oppose the large operations,such as northern Missouri’s Premium Standard Farms, altogether. Missouri has 18 of the giant factory farms, about 340 smaller versions and thousands of even smallerconfinement operations. An amendment to the bill would allow local governing bodies to impose stricter environmental control. Another favorable vote sends the bill to the Senate.
